To compare the effects between electroacupuncture (EA) at Chize (LU 5, the He-Sea point of the Lung Meridian) and Shangjuxu (ST 37, the lower He-Sea point of the large intestine) in rats with ulcerative colitis (UC) on the variations of mesenteric microcirculation and vasoactive intestinal peptide (VIP) in the colon, lung, and hypothalamus. The relative specificity of acupoints was also explored. A total of 28 male Wistar rats were randomized into a normal group, a model group, a Chize (LU 5) group and a Shangjuxu (ST 37) group, 7 rats in each group. The UC model was established by enema with acetic acid. Since the third day after modeling, rats in the Chize (LU 5) group and Shangjuxu (ST 37) group respectively received EA at Chize (LU 5) and Shangjuxu (ST 37), 15 min each time for successive 7 d. The variations of mesenteric microvascular calibers and blood flow status were observed by a microcirculation microscopic tester; VIP in the colon, lung and hypothalamus was measured by radioimmunoassay. Compared with the normal group, the mesenteric microvascular calibers were significantly expanded in the model group (P 0.05); compared with the model group and Chize (LU 5) group, the calibers were obviously shrunk in Shangjuxu (ST 37) group (P 0.05). The colonic VIP levels in the model group and Chize (LU 5) group were significantly higher than that in the normal group (P 0.05). The effects of Chize (LU 5) and Shangjuxu (ST 37) were different in treating UC. Shangjuxu (ST 37) showed a more significant efficacy in down-regulating VIP in the colon and regulating mesenteric microcirculation, while the effects of Chize (LU 5) were not obvious.

To explore the regularity of distribution of press-sensitive acupoints on the body surface in tinnitus patients, so as to provide evidence for selecting suitable acupuncture points in the treatment of tinnitus.Sixty-three cases of tinnitus patients (from 25 to 75 years in age) were recruited in the present study. The patient was asked to take a sitting, supine and prone position, successively, and the operator used the thumb to moderately press the subject's head, neck, back, four limbs below the knee- and elbow joints along the three Hand- and three Foot-A total of 131 press-sensitive acupoints including 41 points with an appea-rance frequency of more than 10 times were found in the 63 tinnitus patients. These 41 acupoints distributing in the top three meri-dians were the Gallbladder Meridian of Foot-Shaoyang, Tri-energizer Meridian of Hand-Shaoyang and Spleen Meridian of Foot-Taiyin, and their involved regions were those below the knee-joints, bilateral sides of the head and marginal portion of the ear, sites bellow the elbow-joints, back-waist, successively in the appearance frequency. The top ten acupoints are Wangu (GB 12), Yifeng (SJ 17), Waiguan (SJ 5), Quchi (LI 11), Sanyinjiao (SP 6), Yanglingquan (GB 34), Fengchi (GB 20), Taichong (LR 3), Shousanli (LI 10) and Zulinqi (GB 41), in sequence.The press-sensitive acupoints in tinnitus patients distribute principally in the Gallbladder Meridian of Foot-Shaoyang, and below the knee-joint, and the most sensitive acupoints are Wangu (GB 12) and Yifeng (SJ 17). These findings may provide an objective basis for clinical diagnosis and treatment of tinnitus.

Background Acupuncture is often used for primary dysmenorrhea. But there is no convincing evidence due to low methodological quality. We aim to assess immediate effect of acupuncture at specific acupoint compared with unrelated acupoint and nonacupoint on primary dysmenorrhea. Methods The Acupuncture Analgesia Effect in Primary Dysmenorrhoea-II is a multicenter controlled trial conducted in six large hospitals of China. Patients who met inclusion criteria were randomly assigned to classic acupoint (N = 167), unrelated acupoint (N = 167), or non-acupoint (N = 167) group on a 1:1:1 basis. They received three sessions with electro-acupuncture at a classic acupoint (Sanyinjiao, SP6), or an unrelated acupoint (Xuanzhong, GB39), or nonacupoint location, respectively. The primary outcome was subjective pain as measured by a 100-mm visual analog scale (VAS). Measurements were obtained at 0, 5, 10, 30, and 60 minutes following the first intervention. In addition, patients scored changes of general complaints using Cox retrospective symptom scales (RSS-Cox) and 7-point verbal rating scale (VRS) during three menstrual cycles. Secondary outcomes included VAS score for average pain, pain total time, additional in-bed time, and proportion of participants using analgesics during three menstrual cycles. Findings Five hundred and one people underwent random assignment. The primary comparison of VAS scores following the first intervention demonstrated that classic acupoint group was more effective both than unrelated acupoint (−4.0 mm, 95% CI −7.1 to −0.9, P = 0.010) and nonacupoint (−4.0 mm, 95% CI −7.0 to −0.9, P = 0.012) groups. However, no significant differences were detected among the three acupuncture groups for RSS-Cox or VRS outcomes. The per-protocol analysis showed similar pattern. No serious adverse events were noted. Conclusion Specific acupoint acupuncture produced a statistically, but not clinically, significant effect compared with unrelated acupoint and nonacupoint acupuncture in primary dysmenorrhea patients. Future studies should focus on effects of multiple points acupuncture on primary dysmenorrhea.

Background. Acupuncture is often used for primary dysmenorrhea. Objective. To assess the efficacy of a single point of acupuncture in the management of primary dysmenorrhea compared with sham acupuncture and no acupuncture. Methodology. Patients with primary dysmenorrhea were randomly assigned to acupoint group ( n = 50), unrelated acupoint group ( n = 50), nonacupoint group ( n = 46), or no acupuncture group ( n = 48). Acupuncture and sham acupuncture were administered once-daily for 3 days with electro-acupuncture at Sanyinjiao (SP6) that was specifically designed to treat primary dysmenorrhea, or an unrelated acupoint (Xuanzhong, GB39), or nonacupoint location. The primary outcome was pain intensity as measured by a 100-mm visual analog scale (VAS) at baseline; 5, 10, 30, and 60 minutes following the start of the first intervention. Cox retrospective symptom scale (RSS), verbal rating scale (VRS), pain total time, and proportion of participants using analgesics were also recorded during three menstrual cycles. Results. The primary comparison of VAS scores demonstrated that patients receiving acupuncture (−15.56 mm, 95% CI −22.16 to −8.95, P < 0.001), unrelated acupoint (−18.14 mm, 95% CI −24.81 to −11.47, P < 0.001), and nonacupoint (−10.96 mm, 95% CI −17.62 to −4.30, P = 0.001) treatment presented significant improvements compared with no acupuncture group. There were no significant differences among the four groups with respect to secondary outcomes. Conclusion. Acupuncture was better than no acupuncture for relieving the pain of dysmenorrhea following a single point of acupuncture, but no differences were detected between acupoint acupuncture and unrelated acupoint acupuncture, acupoint acupuncture and nonacupoint acupuncture.

The objective of this study was to compare immediate effect of acupuncture at SP6 on uterine arterial blood flow in primary dysmenorrhea with that of GB39.This was a prospective, randomized clinical trial.Sixty-six (66) patients with primary dysmenorrhea from the Affiliated Hospital of Shangdong University of Traditional Chinese Medicine were recruited.The SP6 group (n =32) was treated with manual acupuncture at bilateral SP6 for 5 minutes after obtaining needling sensation (de qi) during the period of menstrual pain, whereas the control group (n = 34) was needled at GB39 of both sides for 5 minutes when they suffered menstrual pain.Differences in pulsatility index (PI), resistance index (RI), and ratio of systolic peak and diastolic peak (A/B) in uterine arteries were the main outcome measures.Highly significant reductions were observed in the SP6 treatment group 5 minutes after treatment in menstrual pain scores (8.17 ± 1.90 versus 11.20 ± 2.66; p0.001), values of PI (1.75 ± 0.48 versus 2.32 ± 0.70; p0.001), RI (0.72 ± 0.11 versus 0.78 ± 0.07; p0.001), and A/B (4.33 ± 1.37 versus 5.23 ± 1.67; p0.001). Compared with the GB39 control group, patients in the SP6 treatment group showed significant reductions in 5 minutes after treatment in the changes of menstrual pain scores (3.03 ± 2.36 versus 0.00 ± 0.29; p0.001), values of PI (0.57 ± 0.42 versus -0.10 ± 0.58; p0.001), RI (0.06 ± 0.08 versus -0.03 ± 0.15; p0.01), and A/B (0.90 ± 0.87 versus 0.23 ± 1.02; p0.01). There were no significant changes in menstrual pain scores, values of PI, RI, or A/B before and after treatment in the GB39 control group (p0.05). No adverse events from treatment were reported.This study suggests that needling at SP6 can immediately improve uterine arterial blood flow of patients with primary dysmenorrhea, while GB39 does not have these effects.

Deqi, according to traditional Chinese medicine, is a specific needle sensation during the retention of needles at certain acupoints and is considered to be necessary to produce therapeutic effects from acupuncture. Although some modern researches have showed that Deqi is essential for producing acupuncture analgesia and anesthesia, the data are not enough. It is a paper of a multicenter, randomized controlled study protocol, to evaluate the influences of Deqi on acupuncture SP6 in Cold and Dampness Stagnation pattern primary dysmenorrhea patients, in terms of reducing pain and anxiety, and to find out the relationship between Deqi and the temperature changes at SP6 (Sanyinjiao) and CV4 (Guanyuan). The results of this trial will be helpful to explain the role of Deqi in acupuncture analgesia and may provide a new objective index for measuring Deqi in the future study. This trial is registered withChiCTR-TRC-13003086.

Deqisensation is believed to be important in clinical efficacy according to TCM theory. The measuring method ofDeqisensation has significant implications for the result of research trials. This study makes an investigation on acupuncture-experienced patients and expert acupuncturists in China and aims to find out the patient’s needling sensations and acupuncturist’s sensations which can be acceptable as descriptors ofDeqisensation, so as to provide foundation for more systematic and sensitive quantitative evaluation method ofDeqisensation. Results of this survey indicated that theDeqisensation noted by both patient and acupuncturist is equally important to the treatment efficacy. It is found that there are some differences between the patients’ real-life experience and the acupuncturists’ expectations on patients’Deqisensation. The “dull pain,” “aching,” “sore,” “numb,” “distended,” “heavy,” “electric,” “throbbing,” “warmness,” “coolness,” “spreading,” and “radiating” can be considered as the main manifestations ofDeqisensations. The acupuncturists believed thatDeqisensations were mainly “pulling,” “tight,” and “throbbing.” We suggest developing a questionnaire measuring theDeqisensations which includes both the sensations of the patient and acupuncturist, and this would be very important and necessary for a better understanding of the relationship betweenDeqisensation and acupuncture effects in future studies.

To observe the influence of electroacupuncture (EA) of "Chize" (LU 5, He-sea acupoint) and "Shangjuxu" (ST 37, lower He-sea acupoint) on mesenteric microcirculation, vasoactive intestinal peptide (VIP) levels in the lung, colon and hypothalamus tissues in rats with chronic obstructive pulmonary disease (COPD), so as to investigate its mechanism underlying improvement of lung derived intestinal disorders in clinical practice.Thirty-two male Wistar rats were randomly divided into normal control, model, EA-Chize (LU 5, EA-LU 5) and EA-Shangjuxu (ST 37, EA-ST 37) groups, with 8 rats being in each group. COPD model was established by intratracheal infusion of Lipopolysaccharide (LPS, 1 mg/mL, 0.2 mL/rat) and forced inhaling smoke, once daily for 28 days. EA was applied to bilateral LU 5 and ST 37 for 20 min, once every other day for 12 sessions. The state of mesenteric microcirculation was observed under microscope and divided into grade 0 (stagnation of blood flow), I (slow flowing and silt-like state), II (faster flowing with slight or obvious grainy feeling) and III (fast flowing without grainy feeling). The contents of VIP in the lung, colon and hypothalamus were detected using radioimmunoassay (RIA).Following modeling, the microvascular calibers were increased slightly in the model, EA-LU 5 and EA-ST 37 groups. Compared with the normal group, the blood flow velocity was increased significantly in model group (P0.05). In comparison with the model group, the blood flow velocity was reduced significantly in EA-LU 5 and EA-ST 37 groups (P0.01). There were no significant differences between EA-LU 5 and EA-ST 37 groups in blood flow velocity, among the four groups in VIP contents of the lung tissue (P0.05). The content of VIP in the colon was markedly higher in the model group than in the normal group, and that in the hypothalamus was obviously lower in the EA-LU 5 group than in the model group (all P0.05).EA stimulation of "Chize" (LU 5) can notably reduce hypothalamic VIP content and slow down blood flow velocity of the mesenteric microvessels in COPD rats.

To observe the relationship between the cutaneous temperature of the acupoint area and the environmental temperature and humidity in healthy female undergraduate student volunteers.Forty-nine healthy female undergraduate student volunteers experiencing menstruation were enrolled in the present study. The cutaneous temperature of the acupoint region was detected for 60 min by using a "dynamic skin temperature detector" and under room temperature of (22.15 +/- 1.47) degrees C and indoor relative humidity of (50.12 +/- 4.52)%. The detected acupoints were Xuehai (SP10), Diji (SP8), Zhongdu (LR 6), Sanyinjiao (SP 6), Taixi (KI 3), Taibai (SP 3), Taichong (LR 3) and Shuiquan (KI 5)which have been well documented in effectively regulating uterine activity, and Xuanzhong (GB 39) and non-meridian acupoint nearby GB 39. The skin temperature measurement was conducted on the first day of menstruation.The skin temperature levels of Xuehai (SP 10), Diji (SP 8), Zhongdu (LR 6), Xuanzhong (GB 39) and non-acupoint near GB 39 were apparently hig-her under higher temperature, showing a significant relevance between the acupoint skin temperature and room temperature (P0.05). No significant differences were found between skin temperature levels of Sanyinjiao (SP 6), Taixi (KI 3), Taibai (SP 3), Taichong (LR 3) and Shuiquan (KI 5) and the indoor temperature (P0.05), between the skin temperature difference of the bilateral isonym acupoints and the indoor temperature, and between the skin temperature difference and the indoor humidity (P0.05).The skin temperature of some acupoints is influenced by the environment temperature rather than the indoor humidity.

To observe the effect of electroacupuncture (EA) on plasma thromboxane B2(TXB2) and 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha) levels in dysmenorrhea rats in order to investigate its mechanism underlying relief of primary dysmenorrhea and specificity of acupoint efficacy.Female SD rats with diestrus were randomly divided into saline control (control), model, EA Sanyinjiao (SP 6), EA Xuehai (SP 10), EA Xuanzhong (GB 39) and EA non-acupoint (NAP) groups, with 10 rats in each. Dysmenorrhea model was established by subcutaneous injection of Estradiol Benzoate (0.5 mg/rat on the 1st and 10th day, and 0.2 mg/rat from the 2nd to the 9th day) and intraperitoneal injection of Oxytocin (0.2 mL/rat, 1 h after last injection of Estradiol Benzoate on the 10th day). EA was applied to bilateral SP 6, SP 10, GB 39, and non-acupoint (the mid-point between the Gallbladder and Stomach meridian at the GB 39 level) for 20 min. The latency and score of writhing were recorded for 20 min. Plasma TXB2 and 6-keto-PGF1alpha contents were detected by radioimmunoassay.Compared with the control group, the latency of writhing in the model group was shortened considerably (P0.01), and the writhing score was increased significantly (P0.01). In comparison with the model group, the writhing latency was increased significantly only in the EA-SP 6 group (P0.05), and the writhing scores in the EA-SP 6, EA-SP 10, EA-GB 39 and EA-NAP groups were reduced remarkably (P0.01). Plasma TXB2 content and the ratio of TXB2/6-keto-PGF1alpha. were significantly higher in the model group than in the control group (P0.01). Compared to the model group, plasma TXB2 levels and the ratios of TXB2/6-keto-PGF1alpha. in the EA-SP 6, EA-SP 10, EA-GB 39 and EA-NAP groups were downregulated markedly (P0.05, P0.01), while plasma 6-keto-PGF1alpha was upregulated strikingly only in the EA-SP 6 group (P0.05). No significant differences were found among the EA-SP 6, EA-SP 10, EA-GB 39 and EA-NAP groups in the writhing latency and writhing score, plasma TXB2 and 6-keto-PGF1alpha, levels (P0.05).EA can relieve pain reaction in dysmenorrhea rats, which may be closely associated with its effects in downregulating plasma TXB2, upregulating plasma 6-keto-PGF1alpha, content, and balancing plasma TXB2/6-keto-PGF1alpha. The effect of EA of SP 6 is relatively better.

To investigate the effect of preventive moxibustion at the acupoint of 'Guanyuan" (CV 4) on the stress-related hormones, proteins and genes in natural menopausal rats, and explore its protective mechanism.One hundred and twenty eight healthy female SD rats were used in this study, in which 16 rats aged 4 months were used as normal control group, the rest 10-month-old rats with disorder of estrus cycle were randomly divided into 7 groups, including 4 control groups at the age of 10, 12, 14 and 16 months, and 3 preventive moxibustion groups at the age of 12, 14 and 16 months, 16 cases in each group. The 10-month-old rats were treated with preventive moxibustion at the acupoint of "Guanyuan" (CV 4), twice a week for 8 weeks consistently, then observed on the following 12, 14 and 16 months. Its effects on the level of heat shock protein 70 (HSP 70), heat shock protein 70 mRNA (HSP 70 mRNA), corticotropin-releasing hormone (CRH), beta-endorphin (beta-EP), adrenocorticotrophic hormone (ACTH) in the different nuclei of hypothalamus were examined with radio-immunity, immunohistochemistry or in situ hybridization methods.In the control groups, the expression of HSP 70 and HSP 70 mRNA was increased in paraventricular, arcuate and supraoptic nucleus, the level of CRH, beta-EP was showed with declining trend in volatility, while the content of ACTH was increased. In comparison to the same-aged control groups, the preventive moxibustion groups were showed that the expression of HSP 70 in the 14-month-old group was lower and the expression of HSP 70 mRNA in the 12 and 16-month-old group was significantly higher in the paraventricular nucleus (all P0.05), the expression of HSP 70 in the 12 and 14-month-old groups and HSP 70 mRNA in the 12-month-old group was significantly increased in the arcuate nucleus (P0.05, P0.01), while the expression of HSP 70 in the 14-month-old group and HSP 70 mRNA in the 12 and 16-month-old group was significantly decreased in the supraoptic nucleus (all P0.05), the content of CRH and ACTH decreased significantly in 14-month group (P0.05, P0.01), but the content of beta-EP obviously went up in the 12-month-old group (P0.05).Preventive moxibustion at the acupoint of "Guanyuan" (CV 4) can regulate the expression of stress proteins, genes and hormones in the hypothalamus for the natural menopausal rats, which might be playing a protective role.

To investigate the clinical effects of electroacupuncture (EA) at Fenglong (ST 40) on blood lipids.Two hundred and four patients of hyperlipidemia were randomly divided into a Fenglong group and a Xuezhikang group, 102 cases in each group. The patients in the Fenglong group were treated with electroacupuncture at Fenglong (ST 40). After arrival of qi, the needles were connected with acupoint nerve stimulator (LH 202 H type, HANS). The primary parameters of EA: for high triglycerides (TG) type, AM 50 Hz, intensity 1 mA, needle-retained time 20 min, twice per week; for high cholesterol (CHO) type, AM 100 Hz, intensity 1 mA, needle-retained time 30 min, thrice per week; for high low-density-lipoprotein (LDL-C) type, the same parameters as the high CHO type except the tolerable and comfortable intensity; for the mixing type, corresponding methods were alternatively used. The patients in the Xuezhikang group received Xuezhikang capsule orally, 2 capsules each time and twice daily, for total 11 weeks.The total effective rates of the Fenglong group and the Xuezhi-kang group were 83.0% and 85.9%, respectively, with no significant difference between the two groups (P0.05), and there was no significant differences in the function of regulating blood lipids between the two groups (all P0.05). After one month follow-up survey, the total CHO, TG and LDL-C decreased and high-density-lipoprotein (HDL-C) increased, of which there was a significant difference in TG reduction (P0.05). There were no relapses in both groups.EA at Fenglong (ST 40) can effectively regulate blood lipids with a better after-effect, which can be applied as a safe and effective method to replace medication for regulating blood lipids.

To explore the mechanism of "preventive acupuncture and moxibustion" for regulating hypothalamic function in ovariectomy rats.Thirty female SD rats, aged 3.5 months, were randomly divided into normal group, sham operation group, ovariectomy model group, preventive acupuncture group and preventive moxibustion group. After "preventive acupuncture and moxibustion" were previously given to the preventive acupuncture group and the preventive moxibustion group for one month, respectively. At the same time, ovarietomy was made in the preventive acupuncture group, the preventive moxibustion group and the ovariectomy model group. For the sham operation group, only a little fat around the ovary was removed without ovariectomy, and nothing was not applied to the normal group. Immunohistochemical and in situs hybridization methods were used to investigate changes of expressions of ER-alpha and ER-alpha mRNA in paraventricular nucleus, supraoptic nucleus and arcuate nucleus.In the model group the expressions of ER-alpha and ER-alpha mRNA in paraventricular nucleus and the expression of ER-alpha mRNA in supraoptic nucleus increased significantly (P0.01), but the expression of ER-alpha dropped significantly in both supraoptic nucleus and arcuate nucleus (P0.01). After preconditioning with acupuncture or moxibustion, the expression of ER-alpha mRNA in paraventricular nucleus significantly reduced (P0.05), and the expression of ER-alpha had no significant change (P0.05); the expression of ER-alpha in supraoptic nucleus and arcuate nucleus significantly increased (P0.01 or P0.05), and the expression of ER-alpha mRNA in paraventricular nucleus had no significant change (P0.05)."Preventive acupuncture and moxibustion" at "Guanyuan" (CV 4) have an effect on the expressions of ER-alpha and ER-alpha mRNA in different hypothalamic nuclei in ovariectomy rats, which possibly is one of the ways for modulating the hypothalamic activity.

Acupuncture-related therapies might be an effective intervention for primary dysmenorrhea.To evaluate the effects of acupuncture-related therapies for treating primary dysmenorrhea.A specified literature search was performed of the Cochrane Library, MEDLINE, EMBASE, CNKI, and CBM databases.All clinical controlled trials pertaining to acupuncture-related therapies for primary dysmenorrhea were included, and the quality of the trials was assessed.Two independent reviewers were responsible for data extraction and assessment. The original data of each trial were analyzed with software (Revman 4.2), but a meta-analysis could not be carried out because of the heterogeneity of the trials.Thirty randomized controlled trails (RCTs) and two controlled clinical trials (CCTs) were identified. Most of the trials were of low methodologic quality (six trials were Grade B and 26 trials were Grade C). Data analysis indicated that there were conflicting results regarding whether acupuncture-related therapies were more effective than control treatments. However, there was a small, methodologic sound trial of acupuncture which suggested that acupuncture was more effective than control groups (placebo acupuncture: WMD=-0.57 and 95% CI=-0.76-0.38; standard control: WMD=-.19 and 95% CI=-0.37-0.01; visitation control: WMD=-1.04 and 95% CI=-1.28-0.80).Because of low methodologic quality and small sample size, there is no convincing evidence for acupuncture in the treatment of primary dysmenorrhea. There is an urgent need for randomized, blinded, placebo-controlled trials to assess the effects of acupuncture.

To observe the effect of preventive acupuncture and moxibustion of "Guanyuan" (CV 4) on uterus in ovariectomized (OVX) rats.A total of 80 female SD rats were randomly divided into 5 groups: normal control, sham-operation (sham), model, preventive acupuncture (PA) and preventive moxibustion (PM) groups, with 16 cases in each. PA (with the needle retained for 20 min after insertion) and PM (one moxa-cone/rat) were applied to "Guanyuan" (CV 4) separately before ovariectomy, two times a week, 4 weeks altogether. Then, ovariectomy was performed on rats of model, PA and PM groups. Uterus tissue was taken under anesthesia for homogenate (10 rats/group) or sectioning (5-6 microm, 6 rats/group). Uterus estradiol (E2), progestone (P) were detected with radioimmunoassay; superoxide dismutase (SOD), nitric oxide synthase (NOS), and malondialdehyde (MDA) were assayed with immunoturdidimetry. Partial uterus slices were stained with HE method for observing morphological changes, or stained with immunohistochemical method or with in situ hybridization method for displaying estrogen receptor (ER)-alpha and ER-alpha mRNA expression separately.After ovariectomy, the rat's uterus presented obvious squamous metaplasia, hyperplasy, and thickening of the endomembrane, decrease in glands and blood vessels and increase in fibrous connective tissue, etc; while the situation was evidently better in PA and PM groups. In comparison with normal control group, E2, P contents and SOD, NOS activities of uterus tissue in model group decreased significantly (P0.01), while MDA in model group increased evidently (P0.01). Compared with model group, uterus P content in PA and PM groups increased obviously (P0.05), while uterus MDA decreased apparently (P0.01). Compared with normal control group, the expression of ER-alpha and ER-alpha mRNA in model group was downregulated markedly (P0.01); after PA and PM, both ER-alpha and ER-alpha mRNA expression increased obviously (P0.01). No significant differences were found between PA and PM groups in the above mentioned 7 indexes (P0.05).Preventive acupuncture and moxibustion of CV4 can postpone the structural degeneration of uterus in OVX rats, which may be related to their effects in modulating the secretion of uterus E2 and P, upregulating the expression of ER-a and ER-alpha mRNA, and improving the anti-oxidative ability.

To probe into the target organ of Fenglong (ST 40) and the mechanism in resolving phlegm.Thirty SD rats were randomly divided into 3 groups, a blank control group, a model group and a Fenglong group, 10 rats in each group. The hyperlipemia rat model was prepared by feeding high fat forage. The blank control group were fed by basic forage each day, and other 2 groups were fed with high fat forage each day. After the rats were fed for 2 weeks, EA was given at "Fenglong" (ST 40) in the rats of the Fenglong group, twice each week, for 10 times. At the end of EA treatment, SOD activities and MDA contents in the spleen, lung, liver and pancreas were detected.Acupuncture at "Fenglong" (ST 40) significantly increased SOD activities in the spleen and lung, decreased MDA content in the lung, and had a tendency to decrease SOD activity and to increase MDA content in the liver, while it did not significantly influence SOD activity and MDA content in the pancreas.The target organs of "Fenglong" (ST 40) regulating SOD activity and MDA content are spleen, lung and liver, particularly, spleen and lung, with no relation with pancreas. It is indicated that the resolving phlegm function of "Fenglong" (ST 40) is related with promoting metabolism of free radiations in special organs.

To study the effects of different parameters (frequency, intensity, needle-retained time and treatment interval) of electroacupuncture at Fenglong (ST 40) for adjusting blood lipids, so as to find out the optimization parameter.Fifty-four cases meeting the criteria for hyperlipoidemia were randomly divided into 27 groups with orthogonal design L27 (3(13) ). According to the orthogonal design program they were treated with electroacupuncture at Fenglong (ST 40). Ten sessions constituted one course with a one week's interval between two course. The treatment was given for 2 courses.(1) The parameters of EA at Fenglong (ST 40) for regulating blood lipids in primary and secondary orders are: frequency, needle-retained time, interval of treatment, intensity. (2) The parameters of EA at Fenglong (ST 40) for various programs in regulating various blood lipids are: for TG, frequency AM 50 Hz, needle-retained time 20 ain, intensity 1 mA, twice each week; for TC, frequency AM 100 Hz, needle-retained time 30 min, intensity 1 mA, once every other day; for LDL-C, frequency Am 100 Hz, needle-retained time 30 min, intensity tolerable and comfortable, once every other day.
