To explore the regulating effect of acupuncture on pain based on the three dimensions of pain (pain sensation, pain emotion and pain cognition). The pain sensation is related to the body, the pain emotion is related to the seven emotions, the pain cognition is related to the mind of the five zang , and the three dimensions of pain interact with each other. Through the two ways of "regulating qi to treat mind" and "treating mind to regulate qi ", acupuncture comprehensively acts on pain sensation, pain emotion and pain cognition to achieve comprehensive regulation of pain.

Objective: To observe the clinical effect of single acupoint [Yaotu (extra)] electroacupuncture (EA) therapy on lumbar intervertebral disc herniation (LIDH) and its promotion and application in community medical institutions., Methods: This research adopted a three-level promotion model, and used multi-center collaboration topics as a platform. A total of 240 patients with LIDH were divided into a group A (top three hospital, 80 cases, 3 cases dropped off), a group B (secondary hospital, 80 cases, 8 cases dropped off), and a group C (community health center, 80 cases, 7 cases dropped off). All groups were treated with EA at a single acupoint [Yaotu (extra)] under the guidance of a unified experimental protocol. The EA was given 60 min each time and performed 3 times a week for a total of 2 weeks. The changes of visual analogue scale (VAS) scores of three groups before and after each treatment were compared, and the clinical efficacy was evaluated., Results: Compared with before each treatment, the VAS scores of three groups after each treatment decreased ( P <0.05). Except for the second and fifth treatments, the immediate effect in the group A was higher than that in the group B and C ( P <0.05). The total effective rate of group A, group B, and group C respectively was 90.9% (70/77), 93.1% (67/72), 86.3% (63/73), and there was no statistically significant difference among the three groups ( P >0.05)., Conclusion: The single acupoint EA therapy has a significant effect in the treatment of LIDH, can quickly relieve the pain symptoms, and has the characteristics of simple operation and easy control, suitable for promotion and application in primary hospitals.

The research progress of acupuncture analgesia in recent years is analyzed to summarize the analgesic mechanism of acupuncture on neuropathic pain. The analgesic mechanism of acupuncture on neuropathic pain is discussed from peripheral level and central level, including peripheral sensitization and immune inflammatory response, changes of ion channel, central sensitization, regulation of cell signal pathway, activation of spinal glial cells, etc. It is suggested that the focus of future research should include conducting in-vitro studies with the help of multi-omics technology to detect the changes of metabolic substances and signal pathway molecules in patients with neuropathic pain before and after acupuncture to further clarify the mechanism of acupuncture analgesia.

Objective: To observe the auxiliary analgesic effect of wrist-ankle acupuncture on patients undergoing transforaminal endoscope surgery., Methods: A total of 64 patients with lumbar disc herniation who underwent percutaneous lateral transforaminal endoscope surgery were randomly divided into an observation group and a control group, 32 cases in each group. The patients in the control group were treated with injection of 1% lidocaine for routine local infiltration anesthesia. The patients in the observation group were treated with wrist-ankle acupuncture at lower 5 area and lower 6 area for 30 min, 5 min before routine local infiltration anesthesia; immediately, 15 min, 30 min after insertion the left-right technique, up-down technique, and rotation technique were applied for six times, respectively. The mean arterial pressure (MAP), heart rate (HR), blood oxygen saturation (SpO 2 ) and pain visual analogue scale (VAS) were compared between the two groups at the time points of intraoperative puncture (T 1 ), circular saw grinding (T 2 ), and placement of working channel (T 3 ). The intention of reoperation was recorded immediately after operation and 24 h after operation. The expectation and treatment credibility scale (ETCS) was used to evaluate the relationship between patients' expectation and efficacy 5 min before operation and immediately after operation., Results: At T 2 and T 3 during the operation, the MAP and HR in the obserrvation group were lower than those in the control group, while SpO 2 was higher than that in the control group ( P <0.05). At T 1 , there was no significant difference of MAP, HR and SpO 2 between the two groups ( P >0.05). At T 2 , the peak VAS and average VAS in the observation group were lower than those in the control group ( P <0.05), but there was no significant difference at T 1 and T 3 ( P >0.05). The intention of reoperation in the observation group was higher than that in the control group both immediately after operation and 24 h after operation ( P <0.05). In the observation group, the scores of each item in ETCS immediately after operation were higher than those 5 min before operation ( P <0.05), while in the control group there was no significant difference between immediately after operation and 5 min before operation ( P >0.05). The scores of ETCS1, ETCS2 and ETCS3 immediately after operation in the observation group were higher than those in the control group ( P <0.05)., Conclusion: The wrist-ankle acupuncture has positive auxiliary analgesic effect on lumbago during transforaminal endoscope surgery, and strengthens the patients' confidence on the operation effect.

The clinical research articles relevant with Fu 's subcutaneous needling therapy (FSN) were retrieved from CNKI, WANFANG, CBM and PubMed databases till January 2018 since the establishment of database. According to the general international criteria of disease classification, the diseases involved in the articles were classified and summarized. In terms of the clinical application and research of FSN, the questions were extracted and commented through expert's consultation. As a result, 412 articles were included. The statistical results of disease spectrum indicated that FSN was adopted in 65 kinds of diseases in 11 systems. Of these diseases, the relevant somatic pain disorders in the musculoskeletal system were the most appropriate. Professor FU Zhong-hua explained that the clinical physicians of FSN should select the muscle-related disorders as the clinical research subject and treat them with normalized manipulation of FSN. The research on FSN is still at the preliminary stage. It needs more high-quality clinical and basic researches to provide the evidences for the therapeutic effects of FSN.

Objective: To observe the differences in the clinical effects on cervical spondylosis with neck pain between the grain-moxibustion combined with acupuncture and simple acupuncture., Methods: Eighty-eight cervical spondylosis patients with neck pain who met the inclusion criteria were randomly divided into an observation group and a control group, 44 cases in each one. The patients in the control group were treated with conventional acupuncture, and grain-moxibustion was applied on the basis treatment of the control group in the observation group. The treatment was given 3 times a week, once every other day, 10 times as one course, and followed up after 6 months. Northwick Park neck pain inventory (NPQ) and the McGill pain questionnaire (MPQ) of the two groups before and after treatment and 6 months follow-up were observed. The clinical efficacy was compared., Results: After one course of treatment in both groups, the effective rate was 84.1% (37/44) in the control group and 86.4% (38/44) in the observation group; after 6 months follow-up, the effective rate was 79.5% (35/44) in the control group, and 81.8% (36/44) in the observation group. There was no significant difference in overall efficacy between the two groups (both P >0.05). Compared before treatment, the NPQ scores and MPQ scores were decreased at the end of one course of treatment and after 6 months follow-up in the two groups (all P <0.05). There was no significant difference in NPQ scores and MPQ scores between the two groups after one course of treatment (both P >0.05), but the NPQ scores and MPQ scores in the observation group were significantly lower than those in the control group after 6 months follow-up (both P <0.05)., Conclusion: The immediate efficacy of grain-moxibustion combined with acupuncture for cervical spondylosis with neck pain is similar to that of simple acupuncture, however, the long-term curative effect is better.

"The opening-closing-pivoting theory" recorded in Neijing ( Internal Classic ) visualizes the qi activity of six meridians and indicates the relationship among the six meridians in physiology and pathology. Through the analysis on the classic medical works and modern literature of TCM by the modern medical masters, a specific relationship is discovered among the hand and foot meridians of the same name and among the zangfu organs. The qi is corresponded and interacted among the hand and foot meridians of the same name. Except the exterior and interior relationship among the zangfu organs, the related communication is also existing. Both meridians and zangfu organs are closely related to "the opening-closing- pivoting" theory. This discovery is the inheritance and development of "the opening-closing-pivoting theory" and plays the important role in the guidance of the acupoint selection of clinical acupuncture analgesia.

Objective: To observe the effects of conventional western medication and joss stick moxibustion combined with pricking and cupping for herpes zoster in acute stage, and to explore its analgesic mechanism., Methods: Seventy patients with acute herpes zoster were randomized into an observation group (33 cases after 2 dropping) and a control group (34 cases after 1 dropping). Patients in the observation group were treated with joss stick moxibustion combined with pricking and cupping at local ashi points for 7 times, once every other day. Oral acyclovir, vitamin B 1 and mecobalamin tablets were applied in the control group for continuous 14 days, and interferon injection was used for continuous 6 days, etc. The herpes evaluation indexes of blister stopping time, scab time and decrustation time as well as pain intensity were observed before and after treatment. Peripheral serum substance P (SP) content of herpes local situation was detected. The comprehensive effects were evaluated., Results: The blister stopping time, scab time and decrustation time in the observation group were shorter than those in the control group (all P <0.05). There was no statistical significance for pain relief degree between the two groups ( P >0.05). The pain beginning to ease time and duration time in the observation group were better than those in the control group (both P <0.05). The contents of SP in the two groups decreased after treatment (both P <0.01), and it was better in the observation group ( P <0.05). The total effective rate of the observation group after treatment was 87.9% (29/33), and that of the control group was 85.3% (29/34), which were not statistically significant ( P >0.05). The cured rate of the observation group was better than that of the control group [66.7% (22/33) vs 58.8% (20/34), P <0.05]., Conclusion: Joss stick moxibustion combined with pricking and cupping are effective for herpes zoster, which have quicker and good analgesic effects than conventional western medication. Its mechanism may be related to reducing the content of SP more fast and to a larger degree.

Objective: To observe the regulatory effects of acupoint electric stimulation on the analgesic substances and the relevant indices of nerve-immunity-endocrine system in the patients undergoing general anesthesia anorectal operation., Methods: One hundred and fifty-six patients undergoing hemorrhoids and anal fistula operation were randomized into three groups, 146 cases were included in the analysis. In the No.1 group (48 cases), the conventional intravenous general anesthesia was applied. In the No.2 group (50 cases), besides the conventional intravenous general anesthesia, the acupoint transcutaneous electric stimulation was combined at Neiguan (PC 6), Shenmen (HT 7), Shangliao (BL 31) and Ciliao (BL 32). operation in the No.2 and No.3 groups were lower apparently than that in the No.1 group ( P <0.05, P <0.01)., Conclusions: During the general anesthesia anorectal operation, the acupoint transcutaneous electric stimulation achieves analgesic anesthesia through effectively promoting the release of body analgesic substance and reducing the stress level in the operation. With the comprehensive acupoint selection as Neiguan (PC 6) and Shenmen (HT 7) and the local acupoints, the therapeutic effects are better in comparison with the simple selection of local acupoints. In the No.3 group (48 cases), besides the conventional intravenous general anesthesia, the acupoint transcutaneous electric stimulation was combined at Shangliao (BL 31) and Ciliao (BL 32). The electric stimulation was maintained till the end of operation. The patients' saliva was collected 0.5 h before operation and 1 h after operation separately. The indices that reflect the body pain regulation and nerve-immune-endocrine secretion were detected, such as opiophin protein (OPI), secretory immunoglobulin A (SIgA), saliva amylase (sAA), cortisol (Cor) and tumor necrosis factor α (TNF-α). The pain degree was observed 1 h after operation., Results: In the No.2 group, OPI after operation was higher than that before operation ( P <0.05). The difference value of OPI in the No.2 group was higher apparently than that in the No.1 group and the No.3 group (both P <0.05). SIgA after operation was higher than that before operation in the No.1 group ( P <0.05). The difference values of SIgA, sAA, Cor in the No.2 group were lower apparently than those in the No.1 group ( P <0.05, P <0.01). TNF-αbefore and after operation and its difference value among the groups were not significant statistically (all P >0.05). The pain degrees in 1 h after.

Objective: To discuss the clinical therapeutic effects of electroacupuncture at Neimadian (Extra) and Neiguan (PC 6) on the analgesic effect of thoracic perioperative stage and its effect mechanism., Methods: Sixty cases of esophageal cancer with elective radical resection under general anesthesia were divided into an observation group and a control group according to the operation sequence, 30 cases in each one. In the control group, the general anesthesia was simply applied and sufentanil was administered for patient controlled intravenous analgesia (PCIA) after operation. In the observation group, on the basis of the scheme as the control group, the electroacupuncture was used at Neimadian (Extra) and Neiguan (PC 6) 30 min before anesthesia induction and after operation, with continuous wave, tolerable intensity, lasting for 30 min. Separately, before acupuncture (T1) and 2h (T2), 12h (T3), 24h (T4) and 48h (T5) after operation, the plasma β-endorphin (β-EP), 5-hydroxytryptamine (5-HT) and prostaglandin E 2 (PGE 2 ) were determined. During operation, under the same state (from 50 to 60) of bispectrum of EEG (BIS), the intraoperative anesthetic dose was recorded. Using visual analogue scale (VAS), the pain degree was evaluated at T2, T3, T4 and T5 separately and the grade assessment of the therapeutic effects and safety were recorded at each time point., Results: ①The total dosage of sufentanil in the observation group was less than that in the control group[(1.83±0.56) mg vs (2.54±0.62) mg, P <0.05]. ②VAS scores at T2, T3 and T4 in the patients of the observation group were all lower than those in the control group (all P <0.05). ③The levels of plasma β-EP at T3, T4 and T5 in the observation group were increased significantly as compared with those in the control group (all P <0.05) and the levels of plasma 5-HT and PGE 2 at T2, T3 and T4 were reduced significantly as compared with those in the control group (all P <0.05). ④ The excellent analgesia rates 2h、12h and 24h after operation in the observation group were better than those in the control group (all P <0.05). ⑤The rate of the A grade safety in the observation group was higher than that in the control group ( P <0.05)., Conclusions: Electroacupuncture at Neimadian (Extra) and Neiguan (PC 6) provides the safe and effective postoperative anesthesia of thoracic surgery and reduces the dosage of analgesics during the operation, which is possibly related to the increase of endogenous β-EP and the inhibition on the release of 5-HT and PGE 2 .

Objective: To compare the effects for tooth extraction between acupuncture anesthesia and drug local block anesthesia., Methods: Sixty patients were randomly assigned into an acupuncture group and a drug group, 30 cases in each one. Acupuncture was applied at Hegu (LI 4), Neiting (ST 44) and the affected side Xiaguan (ST 7), and Jiache (ST 6), etc. Arrachement was used after deqi and the needles were retained for 10 min after tooth extraction in the acupuncture group. Compound articaine hydrochloride injection was used to conventional local anesthesia, after which tooth extraction was implemented in the drug group. The effects of anesthesia and analgesia were compared between the two groups with pain rating index (PRI) and visual analogue scale (VAS). Besides, the bleeding amounts and adverse reaction rates during the operation and the blood pressure, pulse, and respiration before and after operation were observed., Results: Tooth extraction was completed, and the excellent rates, PRI and VAS scores were not significantly different in the two groups (all P >0.05). The bleeding amounts and adverse reaction rates in the acupuncture group were lower than those in the drug group ( P <0.01, P <0.05).The blood pressure, pulse and respiratory during surgery remained normal without significance between the two groups (all P >0.05)., Conclusions: The effect of acupuncture anesthesia for tooth extraction is equal to that of drug anesthesia. Its analgesia is complete with stable vital signs and less adverse reactions. It is worthy of popularizing.

The acupuncture direction is closely related with the efficacy of acupuncture analgesia. In this article, the relationship between efficacy of acupuncture analgesia and factors, such as whether the needle towards disease location, whether the needle towards meridian direction, whether the needle following spinal cord direction and whether the needle following muscle direction, were analyzed. The previous clinical and literature research indicated that the needle towards disease location was superior to reverse direction, however, the efficacy of analgesia between needle following and reversing meridian, needle towards and at disease location, needles following and reversing spinal cord direction, needles following and reversing muscle direction was controversial. Therefore, the solutions to these problems will benefit the optimized acupuncture treatment plan for pain disorders.

Objective: To observe the clinical effects on analgesia, tranquilization and prevention of abortion syndrome of artificial abortion operation treated with transcutaneous electrical acupoint stimulation (TEAS) with different acupoint combination and explore the optimal acupoint combination of TEAS in artificial abortion operation., Methods: Two hundred patients intended to artificial operation were randomized into No.1 group[Sanyinjiao (SP 6) + Zusanli (ST 36)], No.2 group[Sanyinjiao (SP 6) + Diji (SP 8)], No.3 group[Sanyinjiao (SP 6) + Taichong (LR 3)], No.4 group (cervical blockage anesthesia with lidocaine) and No.5 group (blank group, without any analgesia measure applied), 40 cases in each one. In the No.1, No.2 and No.3 groups, Sanyinjiao (SP 6) was the main acupoint, combined with Zusanli (ST 36), Dijin (SP 8) and Taichong (LR 3) respectively. TEAS was given 30 min before the operation till the end of operation. Mean arterial pressure, heart rate and oxygen saturation during operation, as well as bleeding amount were observed in the five groups. The visual analogue scale (VAS) score was observed during and 30 min after operation, and Ramsay score was observed during operation. Cervical relaxation degree and the incidence of artificial abortion syndrome were recorded., Results: For VAS score during and 30 min after operation and Ramsay score during operation, the differences were significant statistically in the No. 1, No.2, No.3 and No.4 groups as compared with the No.5 group ( P <0.01, P <0.05). The results in the No.2 group were better than those in the No.1, No.3 and No.4 groups (all P <0.05). For cervical relaxationdegree, the result in the No.2 group was better than that in each of the rest groups ( P <0.01, P <0.05). For artificial abortion syndrome, the incidences in the No.2 and No.3 groups were lower than those in the No.4 and No.5 groups (all P <0.05). For bleeding amount and hemodynamic changes, the differences were not significant statistically among the five groups (all P >0.05)., Conclusions: TEAS apparently reduces pain score during and 30 min after artificial abortion operation and achieves the satisfactory tranguilization effects. The combination of Sanyinjiao (SP 6) and Diji (SP 8) achieves the optimal effect of analgesia, tranquilization, dilating cervix and preventing from artificial abortion syndrome in the operation.

Objective: To explore the anti-inflammatory and analgesia mechanism of electroacupuncture (EA) device of point injection (PI) on rats of inflammatory pain., Methods: 48 Sprague Dawley (SD) rats were randomly assigned into a control group, a model group, an EA+PI group, an EA device of PI (EAPI) group, an EA group and a PI group, eight rats in each one. The rats in the control group were subcutaneously injected with 50 μL of liquid paraffin oil solvent into the dorsum of left hindpaw, while rats in the remaining groups were treated with 50 μL of complete freund's adjuvant (CFA) at identical location to induce the model of inflammatory pain. After model establishment, the rats in the EA+PI group, EAPI group, EA group and PI group were treated with EA+PI,EA device of PI, EA and PI, respectively, once every other day (the 2nd day, 4th day and 6th day). Each treatment was given for 30 min. The mechanical withdrawal threshold, thermal withdrawal threshold and foot swelling before and 1 d to 6 d after model establishment were observed; the western blotting method was applied to measure IL-1β expression in inflammatory tissue of skin., Results: After model establishment, compared with the control group, the mechanical withdrawal threshold and thermal withdrawal threshold were reduced (all P <0.05) and the foot swelling was increased in the rest groups (all P <0.05). After treatment, the mechanical withdrawal threshold and thermal withdrawal threshold in the EAPI group were significantly increased compared with those in the EA+PI group, EA group and PI group (all P <0.05), but the foot swelling was reduced (all P <0.05). The IL-1β expression in the model group was higher than that in the control group ( P <0.05); after treatment, the IL-1β expression in the EAPI group was lower than that in the model group, EA group and PI group (all P <0.05), but no significantly different from that in the EA+PI group ( P >0.05)., Conclusions: The efficacy of EA device of PI on inflammatory pain is superior to EA combined with PI, EA alone and PI alone, which is suitable for further popularization and application.

The efficacy of acupuncture for pain diseases is significant, however, the unified understanding re garding mechanisms of acupuncture analgesia has not been fully reached. In this paper, it is believed that uncoordi nated muscle movement is one of the important causes for pain, while acupuncture could enhance the contact of nerve cells and improve the synergy of muscle movement, so as to achieve the aim of pain relief and even cure.

Objective: To study whether the dose of controlling antihypertensive drug is reduced by transcutaneous electrical acupoint stimulation (TEAS) and the anesthetics, as well as the control of blood pressure (BP) and heart rate (HR) in endoscopic endonasal surgery with general anesthesia., Methods: Sixty patients for selective endoscopic endonasal surgery with general anesthetics and controlling antihypertension involved were selected and randomized into a TEAS group, a sham-TEAS group, 30 cases in each one. The electric pads were attached to bilateral Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6) and Quchi (LI 11), stimulated with Hans-200 apparatus, 3 to 5 mA, 2 Hz/100 Hz in the TEAS group based on the patients' response to comfort. No electric stimulation was applied to the sham-TEAS group. The general anesthesia started after 30 min intervention and lasted till the end of surgery. The BP and HR were observed and recorded at the end of monitoring in operation room, 10 min after tranquilization (T0), 30 min after intervention (Tj, after induction~of general anestiesa (T2), 30 min after surgery start (T3), 60 min after surgery start (T4) and 30 min after extubation (T5). The doses of vecuronium bromide, propofol and nitroglycerin were recorded statistically in surgery, as well as the operative bleeding volume, the operative time, the resuscitation time and the visual analogue scale (VAS) score after resuscitation., Results: Compared with that at T0, the mean arterial pressure (MAP) at T2, T3, T4 and T5 in the TEAS group and at T3 and T4 in the sham-TEAS group was all reduced, indicating the significant difference (all P < 0.01). MAP at T2 and T5 in the TEAS group was lower than that in the sham-TEAS group (both P < 0.01). Compared, with that at T5, except at T2 in the TEAS group (P<0. 05), HR was not different significantly at the rest time points (all P > 0.05). HR was different at T2 to Ts in the sham-TEAS group statistically (all P < 0.01). The doses of vecuronium bromide, propofol and nitroglycerin, the operative bleeding volume, the operative time, the resuscitation time and VAS after resuscitation were not different significantly between the two groups (all P > 0.05)., Conclusion: The general anesthesia with TEAS and anesthetics involved for controlling antihypertension contributes to the control of BP and HR in the patients in endoscopic endonasal surgery. The impacts are not obvious on the doses of antihypertensive drug, the general anesthetics, the operative bleeding volume, the time of resuscitation and the postoperative analgesia.

Objective: To explore a safe and effective scheme of analgesic for labor., Methods: Eighty-four primiparas without contraindication of vaginal delivery were divided into an observation group and a control group, 42 cases in each one. In the observation group, the acupoint injection was given at Zusanli (ST 36) combined with electroacupuncture (EA) at Hegu (LI 4) and Sanyinjiao (SP 6) till the cervical opening at the end of first stage labor. In the control group, the routine respiratory instruction was applied. In 5 min, 10 min and 60 min of acupuncture (the same time points in the control group) as well as at the end of the first and second stage labor, the analgesic effect was assessed for the primiparas of the two groups. The labor stages, adverse reactions, postpartum hemorrhage, postpartum urine retention, newborn asphyxia rate and usage rate of oxytocin were compared between the two groups., Results: In the observation group, in 5 min, 10 min and 60 min of acupuncture as well as at the end of the first and second stages, the visual analogue scale (VAS) was lower apparently as compared with the control group at the corresponding time points (all P < 0.05). The differences in the time limit in the active period, the second and third stages were not significant between the two groups (all P > 0.05). The incidence of adverse reactions and the usage rate of oxytocin were lower than those in the control group [2.4% (1/42) vs 31.0% (13/42); 2.4% (1/42) vs 23.8% (10/42), both P < 0.05]. The differences in postpartum hemorrhage, postpartum urine retention and newborn asphyxia rate were not significant between the two groups (all P > 0.05)., Conclusion: The combination of acupoint injection and EA is the effective analgesic scheme for labor. This scheme effectively alleviates labor pain and has no maternal and child complications.

Objective: To observe the immediate analgesic effect of tendon acupuncture on soft tissue injury in different sites., Methods: A total of 140 cases of soft tissue injury, involving 14 injury sites, were treated with tendon acupuncture. According to the principle of "considering pain as acupoint", based on injury sites, one to three tendon acupoints were selected in each tendon, which were treated with 1 to 5 times. Totally 676 times Of treatment was given. The visual analogue scale (VAS) was used to evaluate the immediate. analgesic effect before and after the treatment., Results: After the treatment, the score of VAS was significantly reduced (4. 20+ 1. 77 vs 2. 43 ± 1. 30, P<0. 001); regardless of the total number of treatment, the score of VAS after each acupuncture was obviously reduced compared with that before acupuncture (all P<0. 001); the score of VAS at each injury sites after treatment was significantly reduced compared with that before treatment (all P<0. 001)., Conclusion: There is an immediate analgesic effect of tendon acupuncture for different sites of soft tissue injury. Also, the effect has been shown in different frequencies of treatment.

Objective: To observe the analgesic effect of electroacupuncture (EA) on collagen-induced arthritis (CIA) rats and its regulating effect on inflammation reaction and the endogenous opioid system of synovial tissues. Methods A total of 30 healthy male Wistar rats were randomly divided into a control group, a model group and an EA group, 10 rats in each one. The chronic pain model of CIA rats was made by cattle type-II collagen in the model group and EA group. Rats in the EA group were treated with EA at "Zusanli" (ST 36) and "Kunlun" (BL 60) for 30 min from 16th day after model establishment, once a day for consecutive 10 days. Rats in the control group did not receive any treatment. Rats in the model group were treated with fixation as the EA group. Threshold of pain, arthritis index, paw swelling were measured before model establishment and 16 d, 20 d, 23 d and 25 d after model establishment. The levels of beta-endorphin (β-END), met-enkephalin (met-ENK), dynorphin A (Dyn A) were measured by radioimmunoassay; the mRNA expressions of mu opioid receptor (MOR), kappa opioid receptor (KOR) and delta opioid receptor (DOR) in synovial tissues of CIA rats were detected by I quantitative polymerase chain reaction (qPCR)., Results: Compared with the control group, threshold of pain was reduced (all P<0. 01), arthritis index was increased (all P<0. 01) and paw swelling was increased (all P<0. 01) in the model group on the 16th day, 20th day, 23rd day, 25th day after model establishment. Compared with the model group, the threshold of pain was increased in the EA group (all P<0. 01), arthritis index and paw swelling were reduced (all P<0. 01) on the 23rd day and 25th day after model establishment. Compared with the control group, the level of Dyn A in synovial tissues of CIA rats was increased in the model group (P<0. 01); the mRNA expressions of MOR, KOR and DOR were down-regulated lower than 0. 5 fold of normal level. Compared with the model group, the level of β-END in synovial tissues of the knee joint was increased in the EA group (P<0. 05), and the mRNA expressions of MOR, KOR and DOR in synovial tissues of CIA rats were up-regulated more than 2 folds of normal level., Conclusion: The intervention of EA on chronic pain of CIA rats is superior, which is likely to be related with effects of EA on anti-inflammation and up-regulation of synovial tissue β-END and MOR, KOR, DOR.

Professor FU Zhonghua's unique clinical experience of Fu's subcutaneous needling (FSN) for cervical spondylosis (CS) is discussed in this paper, which is analyzed from the aspects of recognition of CS pathogenesis, treatment mechanism of FSN, advantage indications of FSN for CS and examples of medical cases. Professor FU introduced the theory of myofascial trigger points (MTrP) into the field of the management of CS. The site of neck MTrP should be carefully examined, and FSN needles for single use are used to sweep the affected area or subcutaneous layer of adjacent upper limb. This method can rapidly improve ischemia and hypoxia state of the relevant muscles and prompt the self-recovery of neck muscles. During FSN treatment, reperfusion approach is recommended to adopt to improve the qi and blood circulation and recovery of neck function.

Objective: To explore the analgesic effect and action mechanism of electroacupuncture (EA) on gastric ulcer rats with liver-depression syndrome., Methods: Through open-field experimental method, 45 qualified SPF-grade male SD rats were selected and divided into a blank group, a model group and an EA group according to random number table method, 15 rats in each group. The model of gastric ulcer rats with liver-depression syndrome was established in the model group and the EA group by using chronic unpredictable stimulation combined with acetic acid burning method. Rats in the blank group did not receive intervention. Rats in the model group were treated with fixation and immobilization for 13 days. Rats in the EA group were treated with EA at "Liangqiu" (ST 34) and "Ganshu" (BL 18); EA voltage was 2 V; disperse-dense wave was selected with 4 Hz of disperse wave and 15 Hz of dense wave, and the intensity of EA was according to the slight vibration of local skin and; muscles; the needles were retained for 20 min, once a day for consecutive 6 days; there was an interval of 1 day' and the treatment was given for 2 weeks. The general condition, open-field experimental result and gastric ulcer index were observed; the western blotting method was applied to measure the expression of vanilloid receptor subtype 1 (VR1) in hypothalamus and gastric antral mucosal, and ELISA method was applied to test the expression of 5-hydroxytryptamine (5-HT) and norepinephrine (NE) in hippocampus., Results: After model establishment, the general behavior condition in the model group was inferior to that in the blank group, which was obviously improved after EA. The range of motion in the model group was less than that in the blank group (P<0.01) while that in the EA group was higher than that in the model group (P<0.01). The ulcer inhibition rate was. 54.95%, and the ulcer index in the EA group was lower than that in the model group (P<0.01). Compared with; the blank group, the expression of VR1 in hypothalamus and gastric antral mucosal in the model group was increased (P<0.05); compared with the model group, the expression of VR1 in the EA group was reduced (P<0.05). Compared with the blank group, the expression of 5-HT an NE in hippocampus in the model group was significantly reduced (both P<0.01); compared with the model group, the expression of 5-HT and NE in the EA group was increased (both P<0.01)., Conclusion: EA at "Liangqiu" (ST 34) and "Ganshu" (BL 18) has certain analgesic effect in gastric ulcer rats with liver-depression syndrome, which is likely to be related with lowering the contents of VR1 in hypothalamus and gastric antral mucosal and increasing the content of 5-HT and NE in hippocampus.

Objective: To observe the difference in the analgesic effect on primary dysmenorrheal between acupuncture and sham acupuncture at Sanyinjiao (SP 6) during menstrual pain and evaluate the impact of psychological effect on acupuncture analgesia., Methods: Sixty subjects were randomized into an acupuncture group and a sham acupuncture group, 30 cases in each one. The conventional acupuncture and sham acupuncture were applied to Sanyinjiao (SP 6) on bilateral sides when menstrual pain began to attack and needles were retained for 30 min each time. Three menstrual cycles were required. The visual analogue scale (VAS) was adopted to determine the scores before and 0. 5 h, 1 h, 3 h, 6 h and 12 h after acupuncture during menstrual pain in each cycle separately., Results: In the acupuncture group, VAS score at each time point after acupuncture was reduced as compared with that at the previous one during menstrual pain in each menstrual cycle, indicating the significant difference (all P<0. 05). In the sham acupuncture group, the scores in 6 h and 12 h of acupuncture were reduced as compared with the previous one, indicating the significant difference (all P<0. 05). After acupuncture, VAS score at each time point in the acupuncture group was lower than that in the sham acupuncture group (all P<0. 05)., Conclusion: The conventional acupuncture at Sanyinjiao (SP 6) achieves the significant analgesic effect on primary dysmenorrheal. The psychological placebo effect of sham acupuncture has no obvious impact on acupuncture analgesia.

Objective: To explore the feasibility and safety on lung resection surgery with the combined method of microinjection acupuncture (MIA) and intravenous anesthesia instead of compound traditional acupuncture and drug anesthesia (ADA)., Methods: Ninety cases of lung resection surgery were randomized into a general anesthesia group, a MIA group and a ADA group, 30 cases in each one. In the general anesthesia group, before surgery, the intramuscular injection of atropine 0. 5 mg was used; during surgery, the anesthesia induction was followed with intravenous injection of fentanyl citrate, propofol and rocuronium bromide and the dosage was increased accordingly; after surgery, the analgesia pump was applied. In the MIA group, on the basis of general anesthesia, before anesthesia induction, the acupoint catgut embedding was applied to Jiaji (EX-B 2) of T4 , T6 and T, , Feishui (BL 13), Xinshu (BL 15) and Geshu (BL 17) on the affected side and bilateral Quchi (LI 11) and Zusanli (ST 36); after surgery, the analgesia pump was applied. In the ADA group, on the basis of general anesthesia, before! anesthesia induction, electroacupuncture (EA) was applied to Hegu (LI 4), Neiguan (PC 6) , Houxi (SI 3) and Zhigou (TE 6) for 30 min; during surgery, EA and intravenous medication were combined at the same acupoints as those before surgery; after surgery, moxibustion and the analgesia pump were applied in combination for analgesia. In each group, the biological indices were monitored during surgery at 11 time points named T. (before anesthesia I induction), T1 (intubation in general anesthesia induction), T2 (skin incision), T3 (rib exposure in muscular incision) T. (chest open), T, (lung removal), T6 (drainage tube implantation), T7 (chest closure), T (muscular stitching), T, (skin stitching) and T0 (extubation). The actual dosage of anesthetics during surgery and the, dosage of fentanyl citrate in analgesia pump were quantified after surgery. Results (1) In the MIA group and ADA group, the increased dosage of fentanyl citrate was less than that in the general anesthesia group [(1. 23±0. 28) µg . kg-1 . h-1 vs (2. 4±0. 54µg. kg-1 . h-1, (1. 1±0. 38µg . kg-1 . h-1 vs (2. 4±0. 54µg. kg-1 . h-1 , both P<0. 05]. The increased dosage of propofol and rocuronium bromide was not different during surgery among the groups (all P>0. 05). (2) In the MIA group and ADA group, after surgery, the increased dosage of fentanyl citrate was less than that in the general anesthesia group [(11. 0±1. 04)µg/kg vs (15. 4±1. 52µg/kg, (11. 5±1. 38µg/kg vs (15. 4±1. 52µg/kg, both P<0. 05], reducing by 25% in comparison. (3) The differences in heart rate and blood pressure at 11 time points during surgery were not significant among the three groups (all P>0. 05)., Conclusion: n The combined method of MIA and intravenous anesthesia significantly reduces the dosage of intravenous anesthetics during and after lung resection surgery as compared with ADA, presenting the similar analgesic effect as simple intravenous medication and the good safety. The combined method of MIA and intravenous anesthesia is much

Objective: To observe the differences in timely effectiveness of immediate analgesia on acute migraine between electroacupuncture (EA) at shaoyang meridian points and non-meridian points., Methods: The randomized controlled trial method was adopted. One hundred and ten cases of acute migraine were randomized into two groups. 55 cases in each one. In the observation group, EA was applied to Fengchi (GB 20), Waiguan (TE 5), etc. In the control group. EA was applied to non-meridian points. Only one treatment was given, and the nee dies were retained for 30 min in the two groups. Separately. at 10 time points, named before acupuncture, in 5 min, 10 min. 20 min and 30 min (at the moment of needle removal), 1 h, 2 h, 4 h, 6 h and 8 h after acupuncture, the pain intensity numerical rating scale (PI-NRS) was adopted to evaluate the pain severity and the adverse reac tion was recorded., Results: (1) The effective rate of imnmediate analgesia was 87. 3% (48/55) in the observation group. significantly higher than 52.7% (29/55) in the control group (P<0.01). (2) NRS of each group was re duced at each time point, from 5 min to 8 h after acupuncture (all P<0.01). (3) NRS score at 30 min after acu puncture in the control group was obviously lower than that in the observation group (P<0.05), but the scores in 2 h, 4 h, 6 h and 8 h after acupuncture in the observation group were lower apparently than those in the control group (all P<0. 01). The differences in the scores in 5 min, 10 min, 20 min and 1 h after acupuncture were not significant (all P>0. 05). (4) For the reducing amplitude of NRS score at the same time point after acupuncture, the results in 20 min, 30 min and 1 h in the control group were higher apparently than those in the observation group (all P<0. 05). But, in 2 h, 4 h, 6 h and 8 h, the results in the observation group were higher apparently than those in the control group (all F<0.05). The differences in 5 min and 10 min after acupuncture were not significant (both P>0. 05). (5) In 24 h after acupuncture, the recurrence rate of migraine was 12. 7% (7/55) in the observation group, which was lower obviously than 34. 5% (19/55) in the control group (P<0. 05). The adverse reaction was not found in the two groups., Conclusion: EA at the shaoyang meridian points achieves the definite immediate analgesia effect on acute migraine and presents the time effectiveness of analgesia.

Objective: To compare the efficacy difference of analgesia and detumescence on ankle sprain among acupuncture at Xiaojie point combined with tendon regulation manipulation, acupuncture at Xiaojie point and tendon regulation manipulation., Methods: Sixty cases of ankle sprain were randomized into a combined therapy group, a Xiaojie point group and a tendon-regulation manipulation group, 20 cases in each one. The combined therapy of acupuncture at Xiaojie point and tendon regulation manipulation, the acupuncture at Xiaojie point and the simple application of tendon-regulation manipulation were applied respectively in the three groups, once a day, 3 treatments were required. The symptom score such as pain, ecchymosis, swelling and motor dysfunction and the total score were observed before and after treatment in the three groups. The different values of pain and swelling scores were compared before and after treatment in the three groups. The efficacy was compared among the groups., Results: The total effective rate was 100.0% (20/20) in each group. But the curative rate was 85.0% (17/20) in the combined group, 65.0% (13/20) in the Xiaojie point tion manipulation group. After treatment, the symptom scores of pain, ecchymosis, swelling and motor dysfunction and the total score were all improved as compared with those before treatment in the three groups (P < 0.01, P < 0.05). The pain score in either the combined therapy group or Xiaojie point group was lower than that in the tendon-regulation manipulation group after treatment (0.20 -/+ 0.41, 0.15 +/- 0.37 vs 0.60 +/- 0.50, both P < 0.05). Swelling score in the Xiaojie point group was different significantly from that in the tendon-regulation manipulation 0.49 vs 06.4 vs. 20+0.41, P < 0.05). The different value of pain score in either the combined therapy group or Xiaojie point group was higher than that in the tendon-regulation manipulation group before group after treatment (0.65 bined therapy group or Xiaojie point group was higher than that in the tendon-regulation manipulation group before and after treatment (2.35 +/- 0.59, 2.45 +/- 0.51 vs 2.00 +/- 0.46, both P < 0.05). The different value of swelling score in the tendon-regulation manipulation group was higher than that in the Xiaojie point group before and after treatment (2.30 +/- 0.57 vs 1.60 +/- 0.60, P < 0.05)., Conclusion: Acupuncture at Xiaojie point combined with tendon-regulation manipulation achieve an apparent effect of analgesia and detumescence on ankle sprain.

Objective: To explore the anesthetic effect of preemptive analgesia of frequency acupoint electrical stimulation on painless-induced abortion as well as its effect on anesthetics dosage., Methods: Ninety cases of early pregnancy who selected painless-induced abortion were randomly divided into two groups, 45 cases in each group. Frequency acupoint electrical stimulation at Ciliao (BL 32) and Shenshu (BL 23), disperse-densewave, 2 Hz/100 Hz in frequency for 15 to 20 min, was applied in the group A, which was followed by intravenous anesthesia of propofol. The intravenous anesthesia of propofol was applied in the group B. The blood pressure (BP), heart rate (HR) and SpO2 before, during and after surgery, anesthetic effect and dosage, waking time and adverse events were observed in the two groups., Results: The BP and HR during and after the surgery in the group A were not statistically different from those before the surgery (all P > 0.05). The BP was reduced and HR was slowed down during the surgery in the group B, which was significantly different from those before the surgery as well as those in the group A (all P < 0.05). The dosage of propofol was (114. 3-+6. 1) mg in the group A. obviously less than (193.2 +/- 8.9) mg in the group B (P < 0.05). The waking time was (5.6 +/- 1.2) min in the group A, obviously less than (10.1 +/- 3.9) min in the group B (P < 0.05). As for anesthetic effect, the incidence of Grade I in the group A was more than the group B (P < 0.05). The adverse events, including nausea, vomiting and contractions pain in the group A were evidently less than those in the group B (all P < 0.05)., Conclusion: The preemptive analgesia of frequency acupoint electrical stimulation could significantly improve anesthetic effect of painless-induced abortion, reduce dosage of anesthetics, shorten waking time of surgery and guarantee the safety of surgery.

Objective: To explore the effectiveness and safety of transcutaneous electrical acupoint stimulation (TEAS) combined with infusion of propofol in anodynia bronchoscopy., Methods: Ninety patients who received selective bronchoscopy were randomized into a group of compound TEAS with infusion of propofol (group A), a group of compound fentanyl with propofol (group B) and a group of simple propofol (group C). In group A, the plaster electrode stimulation was applied at bilateral Hegu (LI 4), Laogong (PC 8), Neiguan (PC 6) and Waiguan (TE 5). The anesthesia was induced after 20 min of stimulation till the end of examination. In group B and group C, the electric stimulation was not adopted. In group B, before anesthesia, fentanyl 1 microg/kg was injected intravenously. Afterwards, the intravenous infusion of propofol was used in the the three groups for anesthesia. The mean arterial pressure (MAP), heart rate (HR), saturation of pulse oximetry (SpO2) and respiratory rate (RR) were recorded at different time points. The induced dosage and total dosage of propofol, examination time, the awakening time and adverse reactions were observed in the patients of each group., Results: The difference in examination time was not significant among the three groups (P > 0.05). The postoperative awakening time in group A was earlier than that in group B and group C [(220.3 +/- 110.5) s vs (285.6 +/- 109.4) s, (290.1 +/- 105.1) s, both P < 0.05]. The total dosage of propofol in group C was larger than those in group A and group B [(288.5 +/- 26.7) mg vs (225.1 +/- 30.2) mg, (230.4 +/- 29.3) mg, both P < 0.05]. The induced dosage in group C was larger than those in group A and group B [(193.7 +/- 42.3) mg vs (152.3 +/- 36.1) mg, (155.4 +/- 40.5) mg, both P < 0.05]. Every life physical sign in group A during examination was more stable as compared with that in group B and group C. The incidence of hypotension and bradycardia in group A were lower than those in group C [3.3% (1/30) vs 26.7% (8/30), 0% (0/30) vs 20.0% (6/30), both P < 0.05]. The adverse incidence of oxygen supply in group A was lower than that in group B [6.7% (2/30) vs 33.3% (10/30), P < 0.05]. Intraoperative awareness and improper memory did not happen in postoperative investigation., Conclusion: In the transcutaneous electrical acupoint stimulation combined with infusion of propofol in anodynia bronchoscopy, the physical sign of patient is stable with less adverse reactions. This method reduces anesthetic dosage and shortens the postoperative awakening time, which can be effectively applied in bronchoscopy.

Objective: To observe the impacts of different frequencies of electroacupuncture (EA) on post-operative cognitive function and the change in serum S-100beta protein under the compound anesthesia of acupuncture and drugs., Methods: One hundred and twenty-four patients of abdominal operation at selective time were randomized into a routine drug anesthesia group (group A, 24 cases), a meridian point 2 Hz group (group B, 26 cases), a me ridian point 2 Hz/100 Hz group (group C, 25 cases), a meridian point 100 Hz group (group D, 24 cases) and a transcutaneous acupoint electric stimulation 2 Hz/100 Hz group (group E, 25 cases). In group A, the endotrachea-lgeneral anesthesia was applied. In the rest groups, the acupuncture anesthesia was induced for 30 min before the endotracheal general anesthesia, at Baihui (GV 20), Yintang (GV 29) and Neiguan (PC 6), with G6805-2 electric acupuncture apparatus used. In group B, the continuous wave and 2Hz in frequency were selected. In group C, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected. In group D, the continuous wave and 100 Hz in frequency were selected. In group E, the disperse-dense wave and 2 Hz/100 Hz in frequency were selected, and the electrode pads were stick on the acupoints and connected with the electric stimulation till the end of operation. Mini-mental state examination (MMSE) was adopted to evaluate and record the changes in cognitive function 1 day before operation and on the 3rd day after operation. The conditions of post-operative cognitive dysfunction (POCD) in the patients and the changes in serum S-100beta protein were monitored before and at the end of operation., Results: The incidence rate of POCD on the 3rd day after operation was 41.7% (10/24) in group A. The incidence rates of POCD were 26.9% (7/26), 16.0% (4/25), 33.3% (8/24) and 16.0% (4/25) in group B, C, D and E separately. Compared with group A, the incidence rate of PCOD in group B, C, D and E were reduced (all P<0.05), the incidence rate in group C and E were lower than that in groups B and D (all P<0.05). At the end of operation, the level of serumS-100beta protein was (0.186 +/- 0.027) microg/L in group A, the levels were (0.165 +/- 0. 028) microg/L, (0.166 +/- 0.027) microg/L, (0.163 +/- 0.025) microg/L and (0.164 +/- 0.025) microg/L in group B, C, D and E separately. The levels of serum S-100beta protein in group B, C, D and E were lower than that in group A separately (all P<0.05)., Conclusion: The general anesthesia assisted with EA at different frequencies reduces the incidence of cognitive dysfunctionand, decreases the level of serum S-100beta protein after intestinal cancer resection. The effects of the meridian point electric stimulation at 2 Hz/100 Hz and the transcutaneous electric stimulation at 2 Hz/100 Hz are the best. Hence, these two approaches of anesthesia deserve to be recommended practically.

Objective: To explore the efficacy of electric acupoint stimulation on shivering in cesarean section., Methods: Eighty cases of parturients, under the America Society of Anesthesiologists (ASA) physical status II , were randomized into a transcutaneous electrical acupoint stimulation (TEAS) assisted anesthesia group (group A) and an anesthesia group (group B). Spinal-epidural anesthesia(CSEA) puncture was applied to both groups and 8 mg of 0. 75% bubivacaine was given by spinal injection, the block level was T4 T8. In group A, TEAS was applied before CSEA at paired acupoints-ipsilateral Hegu (LI 4)-Laogong (PC 8) and Sanyinjiao (SP 6)-Zusanli (ST 36) till ending the surgery. The 4 pair of bilateral acupoints were fixed with self-adhesive electrodes and connected with Han's acupoint and nerve stimulator (HANS, LH402H), the frequency was 2 Hz/ 15 Hz, the intensity was 10- 30 mA and the form was densedisperse wave within the patients' tolarance. The heart rate (HR), mean arterial pressure (MAP), oxyhemoglobin saturation (SPO) and shivering degree were recorded before anesthesia (To), 1 min after anesthesia puncture (Ti), 1 min after the delivery (Tz), during abdomen closure (T3) and at the end of surgery (T4)., Results: The occurrence rate of shivering was 35. 0% (14/40) in group A, which was lower to 67. 5% (27/40, P<0. 05) in group B; the degree of shivering was lighter in group A than that in group B at T2, T3 and T4 (all P<0. 01). In group A, HR was faster at T1 and T2 compared to that at To (all P<0. 05), while at T3 and T4, the HR was the same with that before anesthesia (all P>0. 05). In group B, the HR was faster at T1, T2, T3 and T4 compared to that at T0 (P<0. 05, P<0. 01). In both groups, the MAP was lower at T1, T2 (P<0.05,P<0.01) and resumed to that before anesthesia at T3 and T4 (all P>0.05); there was no statistical significance of SPO2 in both groups (all P>0.05)., Conclusion: TEAS can reduce the occurrence rate of shivering and steady the heart rate in cesarean section.

Objective: To observe the effectiveness and safety of electroacupuncture (EA) at Neimadian (Extra) and Neiguan (PC 6) for analgesia after thoracic surgery., Methods: One hundred and twenty cases of thoracic surgery were randomly divided into an electroacupuncture (EA) group (60 cases) and a medication group (60 cases). EA was applied at Neimadian (Extra) and Neiguan (PC 6) for postoperation analgesia in the EA group, while patient-controlled intravenous analgesia (PCIA) was applied in the medication group. The score of visual analogue scale (VAS), analgesia effect, safety and beta-endorphin level after the treatment in both groups were compared., Results: Compared with those before the treatment, the VAS scores in every time point after surgery were decreased (all P < 0.05), which were lower in the EA group (P < 0.01). The excellent and good rates were 96.7% (58/60) and 75.0% (45/60) seperately, the analgesia effect in the EA group (2 h after operation) was superior to that in the medication group (P < 0.01). The safety degree in EA group was higher to that in the medication group (P < 0.01). Compared with that before the treatment, the beta-endorphin level in two groups after treatment was both increased, which was higher in the EA group (P < 0.01)., Conclusion: Electroacupuncture at Neimadian (Extra) and Neiguan (PC 6) has better analgesia effect (2 h after operation) and safety than PICA on analgesia after thoracic surgery.

Objective: To observe the impacts of transcutaneous acupoint electric stimulation on hemodynamics, anesthetic and relevant complications in patients of transsphenoidal pituitary tumor resection (TPTR)., Methods: Ninety cases of the selective TPTR were randomized into a transcutaneous acupoint electric stimulation group (group T), a sham-acupoint group (group S) and a control group (group C); 30 cases in each one. In group T, the transcutaneous acupoint electric stimulation at Hegu (LI 4), Waiguan (TE 5), Jinmen (BL 63), Taichong (LR 3), Zusanli (ST 36) and Qiuxu (GB 40). In group S, the transcutaneous acupoint electric stimulation was applied to the sham-acupoints. In group C, the acupoints selected were same as those in group T, but the electrode pads were just attached on the related points with no-electric stimulation. The electric stimulation lasted from analgesic induction till the end of the operation. The endotracheal intubation was done under the induction by propofol, fentanyl and vecuronium bromide. Propofol and remifentanil were maintained till the end of operation. Blood pressure, heart rate, bispectral index (BIS) value, anesthetic and postoperative recovery situation were recorded., Results: The hemodynamics maintained stably in each group. In group T, the mean arterial pressure 1 min after intubation, after extubation and during directional force recovery was all lower than the other two groups respectively (all P<0.05). In group T, the effect-site concentration of fentaryl in the exposure saddle area and tumor removal stage was lower than the other two groups (all P<0.05). In 24 h after operation, 2 cases presented nausea and vomiting in group C. There were no relevant complications in the rest groups., Conclusion: The transcutaneous acupoint electric stimulation improves the stability of hemodynamics in perioperative stage, reduces the intraoperative opi oids dosages and improves the quality of anesthetic recovery.

Through literature retrial, the authors aimed at exploring the organ protective effects of acupuncture assisted anesthesia. Acupuncture anesthesia is invented by Chinese medical practitioners according to functions of acupuncture to relieve the pain and regulate phsyological functions of the organs. It can be applied before surgery for depressive prevention. And it can also be adopted during the operation to reduce the dosage of anesthetic drugs. It also has the post-operative effects of relieving pain, preventing nausea and vomiting, protecting the functions of the brain, cardiac muscle, lung, kidney, liver, stomach and intestines. It benefits the micro-circulation and stress rea-ction as well. Further researches should be extencled to other key problems, for example clinical prognsis of acupunctue assited anesthesia.

Objective: Through analysis of oversea published literatures on central effect mechanism of acupuncture in recent years, the general tendency in this filed is discussed so as to provide references for later studies., Methods: Pubmed database from January 2009 to May 2012 is retrieved with the key words of acupuncture and fMRI. As a result, 38 articles are included., Results and Conclusions: Healthy subjects are adopted for most of researches. And studies are carried out through three aspects of response characteristics of acupuncture analgesia, response characteristics of acupuncture specificity and duration of acupuncture effect. However, the brain activities of healthy subjects are obviously different from that of patients. Moreover, acupuncture treatment is also different from modern therapies. Therefore, it is held that patients should be adopted as study subjects in the future studies, and various bias in research designation and implementation course should be avoided.

Objective: To observe the influence of auricular point sticking on incidence of nausea and vomiting and analgesia effect after gynecological laparoscopy, and provide evidence for clinical application of auricular point sticking., Methods: One hundred and twenty cases of selective gynecological laparoscopy under general anesthesia were randomly divided into an auricular point sticking group and a placebo group, 60 cases in each group. In the auricular point sticking group, the auricular point sticking with vaccaria seeds was applied at Shenmen (TF 4), Wei (CO 4) and Jiaogan (AH 6a) before the operation and 1, 5, 9, 23 h after the operation, which were pressed 5 min each point each time. The two ears were proceeded at the same time. In the placebo group, the same point selection, sticking paste was used as the auricular point sticking group, but no sticking or pressing with vaccaria seeds was adopted. The incidence of nausea and vomiting, the usage rate of tropisetron and morphine within 24 hours of the operation, as well as the score of visual analogue scale (VAS) and other adverse reactions at 2, 6, 10, 24 h after the operation were observed respectively., Results: Compared with the placebo group, the incidence of nausea and vomiting [31.7% (19/60), 16.7% (10/60) vs 58.3% (35/60), 35.0% (21/60)], the usage rate of tropisetron [21.7% (13/60) vs 48.3% (29/60)] and morphine [18.3% (11/60) vs 38.3% (23/60)], the VAS scores at all different time points in the auricular point sticking group were all decreased (all P < 0.05), and no adverse reaction was observed., Conclusion: The auricular point sticking could significantly decrease the incidence of nausea and vomiting in patients of gynecological laparoscopy and has positive analgesic effect.

Objective: To observe the impacts on anesthetic dosage and postoperative pain under general anesthesia assisted by auricular-plaster therapy., Methods: One hundred and twenty cases of gynecological laparoscopic surgery were randomized into three groups, 40 cases in each one. In auricular point group A, the magnetic beads were stick on the auricular points which were Shenmen (TF4), Lung (fei, CO14), Spleen (pi,CO13), Stomach (wei, CO4), Large Intestine (dachang, CO7), Adrenal (shenshangxian, TG2 (P)), Endocrine (neifenmi, CO18), Uterus and Pelvic Cavity(penqiang, TF5) etc. In auricular point group B, the magnetic beads were stick on the preauricular points and the corresponding retroauricular points of the ears. In a placebo group, the plasters of the same appearance were stick on the corresponding auricular points of the ears. The anesthetic method was same in three groups and the anesthesia effect were assessed and compared among the three groups., Results: In surgery, the dosage of sufentanil, the narcotic analgesic was (22.08 +/- 7.11) microg in auricular point group A and was (20.19 +/- 7.21) microg in auricular point group B, which were reduced as compared with (26.13 +/- 9.04) microg in the placebo group (both P < 0.05). The difference in the dosage of propofol, the anesthetic was not significant statistically among three groups (P > 0.05). On the 1st day after surgery, the score of pain visual analogue scale (VAS) was (1.77 +/- 1.65) in auricular point group A and was (1.80 +/- 1.96) in auricular point group B, which were reduced as compared with (2.62 +/- 1.46) in the placebo group (both P < 0.05). Before surgery, the serum beta-endorphin (beta-EP) was (198.8 +/- 124.1) pg/mL in auricular point group A and was (207.2 +/-102.7) pg/mL in auricular point group B, which were higher apparently as compared with (143.6 +/- 87.1) pg/mL in the placebo group (both P < 0.05). The differences in the above indices were not significant statistically between the two auricular point groups., Conclusion: The auricular-plaster therapy reduces the dosage of anesthetic, alleviates postoperative pain and acts on tranquilization and analgesia. The effect is not intensified apparently in the treatment for the magnetic beads sticking on both preauricular points and the corresponding retroauricular points of the ears.

Objective: To observe the effects of transcutaneous electrical acupoint stimulation (TEAS) combined with general anesthesia or controlled hypotension on hippocampal neuronal damage and the inflammatory response in peripheral circulation and central nervous system (CNS) after surgery, and to investigate its brain protection mechanism., Methods: Eighteen healthy male beagles aged 6 - 8 months were randomly divided into a general anesthesia group (group G), a controlled hypotension group (group C) and a compound anesthesia acupuncture group (group A), 6 cases in each group. Dogs in group G was anesthetized by isoflurane inhalation, and group C was combined with intravenous infusion of sodium nitroprusside based on isoflurane inhalation to induce hypotension, and followed surgery after achieving the target blood pressure, and group A was combined with TEAS at "Quchi" (LI 11), "Hegu" (LI 4) "Zu sanli" (ST 36) and "Sanyinjiao" (SP 6) based on controlled hypotension, and then brain tissue was taken out on the 72 h after mean arterial pressure (MAP) was returned to baseline levels. The concentration of IL-1beta,TNF-alpha in serum at different time points were detected by ELISA. The expression of IL-1beta, TNF-alpha, Bcl-2, Bax and cleaved caspase-3 were measured by immunohistochemistry, and the apoptosis of hippocampus were detected by TUNEL., Results: (1) At different time points, the concentration of TNFalpha showed the trend of increase first and then decrease, while IL-1beta concentration represented a trend of decrease first and then increase in both group C and group A, but there were no significant differences in cytokine expression between the two groups (all P > 0.05). (2) The ratio of positive cells of IL-1beta, TNF-alpha and caspase-3 in CA1 and CA3 of hippocampus in both group C and A were higher than those in group G (all P < 0.01), and cytokines expression in group A were lower than those in group C (all P < 0.01), and caspase-3 in CA1 in group A was lower than that in group C (P < 0.01). The ratio of Bcl-2/Bax in both group C and A were lower than that in group G (all P < 0.01), and that in group A was higher than that in group C (P < 0.01 in CA1, P < 0.05 in CA3). (3) The apoptosis index (AI) of hippocampal neurons in both group C and A was significantly higher than that in group G (P < 0.01), while AI in CA1 in group A was lower than that in group C (P < 0.01)., Conclusion: The TEAS can regulate the expression of inflammatory factor in hippocampus in animals undergoing general anesthesia or con trolled hypotension surgery, further improving Bcl-2/Bax ratio, inhibiting the expression of caspase-3 and reducing neuron apoptosis in hippocampus so as to play a neuroprotection.

Objective: To observe the effect of electroacupuncture on supplementary analgesia and improvement of adverse reactions induced by dolantin in oocyte retrieval, and to provide scientific and effective evidence for application of electroacupuncture in oocyte retrieval., Methods: One hundred and thirty-four patients undergoing in vitro fertilization and embryo transfer (IVF-ET) were randomly divied into an observation group and a a control group, 67 cases in each group. They were all received intramuscular injection of 50 mg dolantin at 30 mn before the operation, and then the observation group was treated with acupuncture at Baihui (GV 20), pain point (Extra, right), Sanyangluo (TE 8, right), Zusanli (ST 36, right) and ear uterus point (right ear). Pain point and Sanyangluo (TE 8) were received electroacupuncture stimulation after Deqi until the oocyte retrieval operation was finished, and the oocyte retrieval operation was performed in the control group after 30 min of injection of dolantin. The pain grade and score were observed and the adverse reactions during operation or 1 h and 2 h after the operation were recorded., Results: The excellent analgesia rate was 97.0% (65/ 67) in the observation group and 92.5% (62/67) in the control group, with significant difference in the analgesia effect (P < 0.05). The pain grade and pain score in the observation group were both superior to those in the control group (both P < 0.05). There were fewer cases with the adverse reactions i.e. vertigo, sweating, nausea in the observation group than that in the control group during operation or 1 h and 2 h after the operation (all P < 0.05)., Conclusion: In the oocyte retrieval operation, under the guidance of vaginal B ultrasound, electroacupuncture has a good intraoperative supplementary analgesia effect without intraoperative and postoperative adverse reactions induced by dolantin.

Objective: To assess the clinical efficacy on adhesive ileus treated by electroacupuncture (EA) at Zhigou (TE 6) and Zusanli (ST 36), and to explore the different effects of acupoint and non-acupoint., Methods: Forty cases were randomized into an acupoint group and a non-acupoint group, 20 cases in each one. At the same time of the basic treatment, in the acupoint group, EA was applied at bilateral Zhigou (TE 6) and Zusanli (ST 36). In the non-acupoint group, EA was applied at the sites (that were neither on any meridian nor belonged to any acupoint) that were 0.5 to 1 cm lateral to Zhigou (TE 6) and Zusanli (ST 36) on both sides. Acupuncture was given twice a day, lasting for 4 days totally. The situation of abdominal pain, the time for the improvement in abdominal distention, the time of first voluntary defecation, the time of solid food intake and the others were observed., Results: In the acupoint group, the abdominal pain and distention were relieved rapidly as compared with those in the non-acupoint group. The results of the assessment face scale (AFS), the first anal exhaust time [(51.35 +/- 32.40) h vs (101.85 +/- 53.87) h], the first defecation time [(82.70 +/- 57.27) h vs (154.70 +/- 145.28) h] and the first solid food intake time [(119.65 +/- 56. 16) h vs (231.95 +/- 180.89) h] were all remarkably improved as compared with those in the non-acupoint group, presenting the statistical significance (P<0.05, P<0.01). Concerning the case number for the conversion to surgery, the death number and the number for the re-admission in 1 year follow-up visit, there was no significant difference in statistics between two groups (all P>0.05). But, the data suggested that the results were improved in tendency in the acupoint group., Conclusion: EA at Zhigou (TE 6) and Zusanli (ST 36) achieves the good clinical efficacy on adhesive ileus. This therapy can remarkably improve abdominal pain and distention and promote the intestinal peristalsis for the patients and is superior to EA at non-acupoint.

Objective: To observe influence of electroacupuncture (EA) on phosphorylation of extracellular signal-regulated kinases 1/2 (ERK1/2) in spinal cord dorsal horn (SCDH) in rats with acute inflammatory pain induced by complete Freund's adjuvant (CFA), further elucidate the immediate analgesic mechanism of EA via cellular signal transduction., Methods: Fifty-three healthy male SD rats were divided into two batches. The inflammatory pain models of the first batch of 23 rats were established by using CFA. The changes of the paw withdrawal thresholds (PWTs) of rats were observed and positive cells of p-ERK1/2 in affected SCDH were detected by using immunohistochemistry method. The second batch of 30 rats were randomly divided into a blank control group (N group), CFA group and EA group, 10 rats in each group. The rats of CFA group and EA group were induced inflammatory pain by using CFA, and the EA group was treated with EA at 5.5 h after the model establishment. The changes of PWTs and the positive cells of p-ERK1/2 in SCDH were observed., Results: The PWTs of the first batch of rats obviously decreased at 5 h, 3 d, 7 d and 14 d after CFA administration (all P< 0.01). However, the p-ERK1/2 positive cells in affected SCDH only increased at 5 h after CFA-injection and returned to normality at 3 d after the model establishment. In the second batch, compared with that of N group at the same time point, PWTs of rats in both CFA and EA group obviously decreased after the model establishment (both P<0.01). PWTs of rats in EA group which accepted EA treatment once were longer than those before EA treatment and corresponding PWTs in CFA group at the same time point (both P<0.01). Moreover, the numbers of p-ERK1/2 positive cells of affected SCDH increased significantly in CFA group at 6 h after the model establishment (P<0.01), however, which were decreased significantly in EA group (P<0.01)., Conclusion: Inhibiting ERK1/2 activation of SCDH may be one of the pivotal mechanism of cellular signal transduction of the immediate analgesic effect educed by EA.

Objective: To verify the feasibility of electroacupuncture analgesia applied to gynecologic outpatient operation., Methods: Two hundred patients were randomly divided into an electroacupuncture analgesia group and an intravenous anesthesia group, 100 cases in each group. Operation types included artificial abortion, diagnostic curettage and remove of intrauterine divice. The electroacupuncture analgesia group was treated with electroacupuncture at bilateral Hegu (LI 4) and Neiguan (PC 6), and the routine gynecologic outpatient operation was performed under patients' waking state. The intravenous anesthesia group was treated with routine gynecologic outpatient operation after intravenous injection of fentanyl and propofol., Results: The excellent rate and the effective rate of analgesia were 88.0% (88/100) and 100.0% (100/100) in the electroacupuncture analgesia group, and 94.0% (94/100) and 100.0% (100/100) in the intravenous anesthesia group, with no statistically significant differences between the two groups (all P > 0.05). There was no adverse reaction in the electroacupuncture anesthesia group, but 11 cases of adverse reactions in the intravenous anesthesia group., Conclusion: Electroacupuncture analgesia can effectively alleviate the pain during gynecologic outpatient operation and it is simple and safe without adverse reactions.

Objective: To verify the analgesic effect of acupuncture compound anesthesia in functionality nasal endoscopic sinus surgery (FNES)., Methods: Ninety patients undergoing FNES were randomly divided into three groups. Group A was treated with routine local anesthesia, and group B and C were treated with electroacupuncture at Yintang (EX-HN 3) and Yingxiang (LI 20) for 30 min before local anesthesia. Group B received routine local anesthesia, and group C received decrement local anesthesia. The dosage of narcotic, modified fingers pain scores and postoperative satisfaction scores were observed in three groups., Results: The operative dosage of decicaine was (118.33 +/- 26.21) mg in group A, (100.83 +/- 4.56) mg in group B, and (71.33 +/- 8.90) mg in group C, with significant differences among the three groups (all P < 0.01), the lowest dosage was used in group C and the highest dosage in group A. The fingers pain scores of group B and C were both lower than that of group A (both P < 0.01), and the postoperative satisfaction scores of group B and C were both higher than that of group A (both P < 0.01)., Conclusion: Acupuncture compound anesthesia can effectively alleviate the pain, decrease the dosage of local anesthetic, lower the discomfortableness and be helpful for safety of the patients during sinus surgery.

Objective: To explore different frequency electroacupuncture in acupuncture-drug compound anesthesia on analgesic effect and immune function in the pulmonary resection patients in order to recommend the best electroacupuncture frequency in acupuncture-drug compound anesthesia., Methods: One hundred and sixty-three patients scheduled for pneumonectomy were randomly divided into group A (n = 31), B (n = 34), C (n = 32), D (n = 34) and E (n = 32). Houxi (SI 3), Zhigou (TE 6), Neiguan (PC 6) and Hegu (LI 4) were selected in the five groups. Group A was treated with sham acupuncture by pasting needles without needle bodies at acupoints and electroacupuncture at the needle handle, and group B with 2 Hz electroacupuncture, and group C with 2 Hz/ 100 Hz electroacupuncture, and group D with 100 Hz electroacupuncture, and group E with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation, and general anesthesia was produced in all the groups followed by 30 min electrical stimulation and the stimulation was lasted till the end of operation. The dosages of the anesthetics and the changes of surface antigen of leukomonocyte (CD3+ , CD4+ , CD8+ and CD4+/CD8+) and natural killer (NK) cell were observed at 1 day before surgery, intraoperative and 1 day after surgery., Results: In comparison with group A, the dosages of Propofol in group B and D were decreased, Fentanyl in group B, D and E were decreased. CD3+ and CD4+ in 5 groups increased at first and then decreased over time (all P < 0.01), and group E and C could inhibit the decrease of CD3+ and CD4+ in postoperation in comparison with that in the other three groups (all P < 0.05). CD8+ in 5 groups has no change in different times (all P > 0.05), and group E and D could inhibit the decrease of CD8+ in postoperation in comparison with that in the other three groups (all P < 0.05). CD4+/CD8+ in 5 groups has no change in different times (all P > 0.05), and group E and C could inhibit the decrease of CD4+/CD8+ in postoperation in comparison with that in the other three groups (all P < 0.05). NK cells of 5 groups were increased gradually in different times (all P < 0.01), with the similar regulation of NK cells (all P > 0.05)., Conclusion: Acupuncture-drug compound anesthesia with 2 Hz and 100 Hz electroacupuncture together with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation have the best analgesic effect, and 2 Hz/100 Hz transcetaneous acupoints electrical stimulation and 2 Hz/100 Hz electroacupuncture have the best regulation of immune function. Acupuncture-drug compound anesthesia with 2 Hz/100 Hz transcetaneous acupoints electrical stimulation is recommended for that it can not only decrease the dosages of the anesthetics, but also significantly improve the immunosuppression in patients undergoing pneumonectomy.

Objective: To observe the influence of acupuncture-drug compound anesthesia with different frequency electroacupuncture on cytokine expression in patients with pneumonectomy in order to provide evidence for selection of electroacupuncture frequency in acupuncture-drug compound anesthesia., Methods: Fifty-six patients scheduled for pneumonectomy were randomly divided into groups I (n=22), II (n=16) and III (n=18). General anesthesia was produced in all the groups. The patients in group II and III were treated with electroacupuncture at Houxi (SI 3), Zhigou (TE 6), Neiguan (PC 6) and Hegu (LI 4), 30 min before general anesthesia. The 2 Hz continuous wave was produced in group II, and the 2 Hz/100 Hz was produced in group III till the operation finished. The serum content of interleukin 1 (IL-1) and 6 (IL-6) was detected by double antibody sandwich enzyme linked immunosorbent assay (ELISA) at the time of 24 hours before operation, 10 minutes after incision and 24 hours after operation., Results: The contents of IL-6 in all the three groups at the time of 10 minutes after incision were all higher than those before operation (all P < 0.01), and the content of IL-1 had no obvious change (all P > 0.05). In comparison with 10 minutes after incision, the contents of IL-1 in group I and III were both significantly increased at the time of 24 hours after operation (both P < 0.01), and there was no obvious change in group II (P > 0.05). The contents of IL-6 in all the three groups at the time of 24 hours after operation were more significantly increased than those at the time of 10 minutes after incision (all P < 0.01)., Conclusion: Acupuncture-drug compound anesthesia with 2 Hz frequency can partly regulate the expression of inflammatory factors so as to alleviate the stress reaction in perioperative patients and protect organs function.

In view of the characteristics of different analgesic methods applied to nasal operation, the principle of point selection in acupuncture anesthesia, the frequency of electroacupuncture and the assessment of operation, it was stated that the compound acupuncture anesthesia not only prevented from incomplete analgesia of local anesthesia, but also avoided the adverse reactions of general anesthesia in this paper. Moreover, by reducing the dose of narcotics, the unique advantage of acupuncture anesthesia could be displayed. At present, it was initially believed that a satisfactory analgesia could be achieved by acupuncture at Yingxiang (LI 2) and Yintang (EX-HN 3), with 30 Hz, continuous wave. But there were not many clinical reports on the application of acupuncture anesthesia in nasal endoscopic operation and the operation was not normalized enough. It was expected to optimize the operation procedure of nasal operation under acupuncture anesthesia and promote the clinical practice of it.

Objective: To explore the best acupoint combination of acupuncture-assisted anesthesia in gynecologic laparoscopy operation., Methods: Ninety patients, with American Society of Anesthesiologists (ASA) physical status I - II, and scheduled for elective gynecologic laparoscopy operation, were randomly divided into 3 groups, 30 cases in each group. Group I received only general anesthesia, group II and group III received general anesthesia after Han's acupoint nerve stimulator (HANS) administered for 30 min, bilateral Zusanli (ST 36) and Sanyinjiao (SP 6) were selected for group II, and bilateral Hegu (LI 4) and Taichong (LR 3) were selected for group III. During operation, the concentration of Seveflurine was adjusted to maintain NTS at D1-D2. The change of ETsev value was recorded, the heart rate (HR) and blood pressure (BP) were observed, and the time from the end of operation to extubation, awake time were recorded adverse events such as restlessness, shivering, postoperative pain, nausea and vomiting, cases of respiratory depression, the analepsia quality, the time of first anus exhaust, the awaking of patient in operation and satisfactory of patients after surgery were recorded so as to evaluate the effect of acupuncture anesthesia., Results: Compared with group I, the ETsev in group II was decreased 35% (P < 0.05), group ifi was decreased 25% (P < 0.05), with a significant difference between group II and group III (P < 0.05). BP and HR had more stability in group II and group III, the best in group II. As for the time from the end of operation to extubation and the time from the end of operation to open the eye on command, group I was the longest (all P < 0.05), group III was longer, group II was the shortest. The score of restlessness, postoperative pain, vomiting and in analepsia were the highest in group I (all P < 0.05), higher in group III and the lowest in group II. Consciousness score was lowest in group I (P < 0.05). As for the satisfactory of patient after operation, it was higher in group II and group IIII (both P < 0.05 ) than group I. The time of first anus exhaust in group II and group III were significantly shorter than that in group I (both P < 0.05)., Conclusion: Han's acupoint nerve stimulator has a certain adjuvant action for general anesthesia and analgesia and acupuncture point combination with both Zusanli (ST 36)and Sanyinjiao (SP 6) have the best effect in gynecologic laparoscopy operation. It can decrease the dosage of anaesthetic, has a stable effect on HR and BP during the surgery and has a better quality of analepsia.

Objective: To investigate therapeutic effects of balance acupuncture on scapulohumeral periarthritis (SP)and the mechanisms., Methods: Thirty male New Zealand rabbits were randomly divided into a blank group (group B), a model group (group M) and a balance acupuncture group (group BA) with 10 rabbits in each group. SP model was established by using persistent mechanical strain and ice compress. Balance acupuncture at "Jiantong" point was applied in the animals in group BA, but not in the rabbits of the other two groups. Joint movement and pathological changes in tissues around the affected shoulder joint were observed, and interleukin-1beta (IL-1beta), 5-hydroxytryptamine (5-HT) in plasma and the affected surrounding tissues, and DNA contents in tendon of supraspinatus muscle were measured., Results: The content of plasma 5-HT in group BA [(18.16 +/- 4.44) ng/mL] was significantly lower than that in group M [(23.28 +/- 5.89) ng/mL] (P < 0.05), but without obvious difference in IL-1beta content between the two groups (P > 0.05). Compared with group M, the contents of IL-1beta, 5-HT in affected surrounding tissues, and DNA expression in tendon of supraspinatus muscle were significantly lowered to va rious extent in group BA (P < 0.01, P < 0.05)., Conclusion: Balance acupuncture can effectively improve local and systemic pathological situation induced by SP by way of reducing pain-producing factors, inflammatory factors and DNA expression to alleviate local organization and adhesions in rabbits with experimental SP.
