Background: Sympathetic and parasympathetic nerve remodeling play an important role in cardiac function after myocardial ischemia (MI) injury. Increasing evidence indicates that electroacupuncture (EA) can regulate cardiac function by modulating the autonomic nervous system (ANS), but little is known about its effectiveness on neural remodeling post-MI. Objectives: To investigate the role of EA in ANS remodeling post-MI. Methods: Adult male C57/BL6 mice were equally divided into the Control (Ctrl), MI and EA groups after generating the MI model by ligating the left anterior descending (LAD) coronary artery. Echocardiography and 2,3,5-triphenyltetrazolium (TTC) staining were employed to evaluate cardiac function and infarct size after EA treatment for five consecutive days. Serum norepinephrine (NE) levels were measured by ELISA to quantify sympathetic activation. Then, ANS remodeling was detected by immunohistochemistry (IHC), RT-qPCR, and Western blotting. Results: Our preliminary findings showed that EA increased ejection fraction and fractional shortening and reduced infarct area after MI injury. Serum NE levels in the EA group were significantly decreased compared with those in the MI group. IHC staining results demonstrated that the density of growth associated protein (GAP)43 and tyrosine hydroxylase (TH) positive nerve fibers in the EA group were decreased with increased choline acetyltransferase (CHAT) and vesicular acetylcholine transporter (VACHT). Meanwhile, the results verified that mRNA and protein expression of GAP43 and TH were significantly inhibited by EA treatment in the MI mice, accompanied by elevated CHAT and VACHT. Conclusions: EA treatment could improve cardiac function and reduce infarct size by modulating sympathetic and parasympathetic nerve remodeling post-MI, thus helping the cardiac ANS reach a new balance to try to protect the heart from further possible injury.

Manganese chloride (MnCl2) has been shown to inhibit the Yes-associated protein (YAP) in high-fat diet-fed ApoE−/− mice. Although YAP has been implicated in atherogenesis, there are limited data on the effects of MnCl2 on cardiac remodeling. In this study, we discovered, by electrocardiography, that hyperlipidemia led to spontaneous supraventricular arrhythmia (SVA) in ApoE−/− (KO) mice, with 3 of 9 KO + MnCl2 mice (33%) exhibiting lower incidence of spontaneous SVA than KO mice (6 of 10 mice, 60%). Echocardiography revealed that reduced systolic function in KO mice was reversed by MnCl2 treatment. Oil Red O staining of the aortas and biochemical analysis of lipid levels showed that MnCl2 inhibited plaque formation in a lipid metabolism-independent manner. MnCl2 inhibited inflammatory cell infiltration and reduced fibrosis, as evidenced by hematoxylin and eosin, immunohistochemical and Masson's trichrome staining, respectively. Our findings demonstrate that spontaneous SVA and reduced systolic function were blocked by MnCl2. Our findings show that MnCl2 was useful in delaying cardiac remodeling and reducing susceptibility to spontaneous SVA in a mouse model of hyperlipidemia.

The field of moxibustion research is expanding, with a rapid increase in publications in recent years. Moxibustion is a therapy that ignites moxa on the skin of humans, with an increase in peripheral skin temperature and localized redness. During this treatment, the recipient must remain still to prevent scalding and expose intervention sites for easy manipulation; however, maintaining a fixed posture during moxibustion is a big challenge for animals. Thus, manipulating moxibustion in small animals, such as mice, can lead to several difficulties for researchers. In addition, an uncomfortable posture for animals can lead to fear and resistance to moxibustion, increased risk of injury, diminished animal welfare, and less valid research data. An efficient, comfortable moxibustion method is needed to protect animal welfare and minimize the adverse effects on experimental results. However, moxibustion methods are highly variable and often have limited efficacy. More importantly, an uncomfortable moxibustion posture might cause a stress response, such as those observed with anxiety, fear, and anger, which could influence the research data. Therefore, strategies for animal moxibustion that inflict the least harm possible during the intervention are required. This protocol introduces a mouse tethering method for moxibustion intervention, minimizing mouse discomfort and improving study efficiency. Essential strategies for tethering mice and application of moxibustion are highlighted, and the structure of the tethering instrument is described.

A newly-developed "Mouse Forelimb Fixator" and two types of "Batch Mice Moxibustion Device" on the basis of our "Mouse Safe and Fast Fixation Board" (developed in 2012) were introduced in the present paper. The Forelimb Fixator inserted into the base part of the apparatus in tenon and mortise style is used to control the mouse's posture with the forelimbs' acupoints fully exposed, and can realize simultaneous fixation of several mice at the same time. By using the mobility of the base of the single-hole moxibustion frame and the magnet, the distance between the acupoint surface and the tip of the ignited moxa stick can be accurately controlled, and several acupoints of different meridians can be simultaneously stimulated at the same time. Utilizing the porous transparent moxibustion board, the Batch Mice Moxibustion Device can meet the requirement of moxibustion at multiple acupoints at the same time. In addition, these devices are convenient in operation, innovative in creativity, save manpower and material resources, and help improve experimental efficiency and research on moxibustion.设计一种新型的小鼠固定器及两种穴位批量艾灸装置。小鼠固定器添加前肢固定片，可使小鼠保持前肢穴位充分暴露姿势；固定器榫卯式插入底座，实现多只小鼠同时固定。运用单孔艾灸架底座和磁铁的可移动性，精准调控穴位与灸距，对小鼠不同经脉腧穴进行艾灸；运用多孔透明艾灸板，可满足多个穴位同时艾灸。此小鼠固定器和两种艾灸装置操作方便，创意新颖，节省人力物力，有助于提高实验效率，推动艾灸实验研究。.

Background The pathological process of myocardial ischemia (MI) is very complicated. Acupuncture at PC6 has been proved to be effective against MI injury, but the mechanism remains unclear. This study investigated the mechanism that underlies the effect of acupuncture on MI through full-length transcriptome. Methods Adult male C57/BL6 mice were randomly divided into control, MI, and PC6 groups. Mice in MI and PC6 group generated MI model by ligating the left anterior descending (LAD) coronary artery. The samples were collected 5 days after acupuncture treatment. Results The results showed that treatment by acupuncture improved cardiac function, decreased myocardial infraction area, and reduced the levels of cTnT and cTnI. Based on full-length transcriptome sequencing, 5083 differential expression genes (DEGs) and 324 DEGs were identified in the MI group and PC6 group, respectively. These genes regulated by acupuncture were mainly enriched in the inflammatory response pathway. Alternative splicing (AS) is a post-transcriptional action that contributes to the diversity of protein. In all samples, 8237 AS events associated with 1994 genes were found. Some differential AS-involved genes were enriched in the pathway related to heart disease. We also identified 602 new genes, 4 of which may the novel targets of acupuncture in MI. Conclusions Our findings suggest that the effect of acupuncture on MI may be based on the multi-level regulation of the transcriptome.

Aldosterone induces cardiac electrical and structural remodeling, which leads to the development of heart failure and/or atrial fibrillation (AF). However, it remains unknown whether aldosterone-induced remodeling may modulate the efficacy of anti-AF drugs. In this study, we aimed to jeopardize the structural and functional remodeling by aldosterone in rats with aorto-venocaval shunts (AVS rats) and evaluate the effect of acehytisine in this model. An AVS operation was performed on rats (n = 6, male) and it was accompanied by the intraperitoneal infusion of aldosterone (AVS + Ald) at 2.0 µg/h for 28 d. The cardiopathy was characterized by echocardiography, electrophysiologic and hemodynamic testing, and morphometric examination in comparison with sham-operated rats (n = 3), sham + Ald (n = 6), and AVS (n = 5). Aldosterone accelerated the progression from asymptomatic heart failure to overt heart failure and induced sustained AF resistant to electrical fibrillation in one out of six rats. In addition, it prolonged PR, QT interval and Wenckebach cycle length. Acehytisine failed to suppress AF in the AVS + Ald rats. In conclusion, aldosterone jeopardized electrical remodeling and blunted the electrophysiological response to acehytisine on AF.

BACKGROUND: With the continuous progression of a new generation of adjuvant chemotherapy, the survival time of breast cancer patients has also been significantly improved. Chemotherapy alone will cause a series of side effects, which will seriously affect the quality of life of breast cancer patients. Chinese medicine combined with neoadjuvant chemotherapy has a unique advantage in the treatment of breast cancer. METHODS: English databases were searched using combinations of the following search terms: “traditional Chinese medicine”, “neoadjuvant hemotherapy”, “breast cancer”, and “tumor of breast”. Publications in which traditional Chinese medicine (TCM) combined with neoadjuvant therapy was the experimental group and chemotherapy alone was the control group were screened. RESULTS: A total of 12 publications were included in the meta-analysis. The efficiency of the performance status score was used to test for heterogeneity, Chi(2)=2.95, df=5, P=0.71>0.1, I(2)=0%, Z=3.36, odds ratio (OR) =2.61, and 95% confidence interval (CI), 1.49–4.58. The results of the heterogeneity test of the effective rate of the objective curative effect were as follows: Chi(2)=1.04, df=7, P=0.99>0.1, I(2)=0%0.1, I(2)=0%

Objective. The aim of this study was to investigate the difference of efficacy between conventional moxibustion (CM) and smoke-free moxibustion (SM) for patients with osteoarthritis of the knee (KOA). Methods. This is a multicentre, randomized, single blinded, parallel-group clinical trial. Patients with KOA were randomly allocated to CM group (69) and SM group (69) in 7 hospitals of China. Moxibustion treatment in 12 sessions over 4 weeks was administrated at 3 acupuncture points (EX-LE4, ST35, and ST36). Patients completed standard questionnaires at baseline and after 2 weeks, 4 weeks, 8 weeks, and 12 weeks. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) from the baseline to 4 weeks. The secondary outcomes include Visual Analogue Scale (VAS) and Patient Global Assessment score (PGA). Results. Analyses showed that the WOMAC score improved in pain (95% CI,-0.1[-1.2 to 0.9], p=0.76), stiffness (95% CI,-0.1 [-0.5 to 0.3], p=0.71), and function (95% CI, 2.2 [-1.3 to 5.8], p=0.22) compared between the two groups at 4 weeks, as well as the VAS score (95% CI,0.1 [-0.3 to 0.6], p=0.60). Similar results presented at 8 and 12 weeks. No statistically significant difference was observed between CM and SM groups for outcome measurements. Conclusions. It suggested that smoke generated during moxibustion treatment does not affect the efficacy of moxibustion in the treatment of KOA, which should be taken into account to be removed for the sake of reducing environmental pollution or moxa smoke exposure of acupuncturists or patients. This trial is registered with Clinical Trials.gov, NCT02772055.

The aim of this study was to investigate whether contralateral moxibustion would generate a similar analgesic effect with ipsilateral moxibustion. Contra- and ipsilateral moxibustion were separately applied to Zusanli (ST36) acupoints of inflammatory pain mice. The analgesic effect was evaluated, respectively, by licking/biting time (LBT) of formalin-induced inflammatory pain and thermal withdrawal latency (TWL) of complete Freund’s adjuvant- (CFA-) induced inflammatory pain. For formalin-induced pain, compared with formalin group, the total LBT of ipsi- and contralateral moxibustion reduced in both phase I and phase II, but there was no significant difference between ipsi- and contralateral moxibustion. For CFA-induced inflammatory pain, compared with CFA group, TWL of ipsi- and contra-Moxi groups increased immediately after moxibustion intervention; however there was no obvious difference between ipsi- and contralateral moxibustion at any timepoint. It indicated that contralateral moxibustion had a similar analgesic effect with ipsilateral moxibustion in both formalin- and CFA-induced pain. These results suggest that both ipsi- and contralateral moxibustion could be applied for pain relief.

The therapeutic effect of grain-sized moxibustion (GS-Moxi) on inflammatory pain has been well recognized clinically, but the mechanism remains unclear. STIM1/ORAI1 is a sensible temperature channel, therefore; this study aimed to investigate the analgesic effect of GS-Moxi and the association with STIM1/ORAI1 expression. CFA-induced inflammatory pain model was established and was treated with GS-Moxi after 3 days of CFA injection. The behavioral test was measured after the GS-Moxi; then, serum was prepared for IL-1β, IL-6, and TNF-α, and the stimulated skin was used for measuring STIM1 and ORAI1 expression. The results indicated GS-Moxi had an analgesic effect on inflammatory pain and the heat variation was significant for the analgesia. GS-Moxi decreased the expression of IL-1β, IL-6, and TNF-α. Immunofluorescence and western blot analysis illustrated that heat change was associated with the stimulation of STIM1 and ORAI1. Suggesting that heat variation created by GS-Moxi could be crucial in this therapy and STIM1 and ORAI1 were potential enhancers in regulating analgesia of GS-Moxi.

ObjectiveThe purpose of this study was to evaluate the difference of efficacy between moxibustion (experimental group) and local diclofenac sodium gel (control group) in the treatment of knee osteoarthritis (KOA).MethodsA multicenter, double-blinded, double-placebo, randomized controlled clinical trial was conducted in this research. 144 participants with knee osteoarthritis were randomly divided into two groups according to 1:1 ratio. The participants in the experimental group were treated with active Moxibustion plus placebo gel, whereas the control group was given diclofenac sodium gel plus placebo moxibustion. Moxibustion treatment was administrated at 3 acupoints (EX-LE4, ST35, ST36) for 4 weeks in 12 sessions. The entire trial cycle lasted 13 weeks, including 1 week at baseline, 4 weeks at treatment and 8 weeks at follow-up. Diclofenac sodium gel or placebo gel at a dose of 4 g per knee were applied three times per day for 4 weeks. The primary outcome measures were the changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Secondary outcome measures included changes in other subscales of WOMAC (pain, stiffness and function), visual analogue scale (VAS) and participant overall assessment (PGA).ResultsThe analysis showed that both the experimental group and the control group at 2 weeks, 4weeks, 8weeks and 12 weeks were statistically significant compared with baseline (P 0.05). At 8 weeks, WOMAC total score (95% CI, 4.3 [0.5 to 8.1], P=0.03), pain score (95% CI, 1.0 [0.2 to 1.9], P=0.02) and functional score (95% CI, 3.0 [0.1 to 5.8], P=0.04) the control group are better than the experimental group (P < 0.05). At 12 weeks, there were no significant difference between the two groups (P > 0.05). ConclusionsDuring the treatment, moxibustion has the same therapeutic effect as local diclofenac sodium gel, which can alleviate the pain of KOA participants to different degrees, rigidity and dysfunction. The therapeutic effect of it can basically maintained until 2 months after treatment. Local diclofenac sodium gel was superior to moxibustion in relieving knee pain and knee dysfunction at 8 weeks.Trial registration number Clinical Trials.gov, NCT02769572.Date of trial registration May 2016＃These authors contributed equally to this work.

OBJECTIVE To investigate the effects of long-term exposure to moxa smoke on acupuncturists and to consider the association between physical symptoms and gender, age, secondhand smoke (SHS) exposure, and the duration of exposure. METHODS A self-report, web-based questionnaire was used to evaluate the effects of moxa smoke on acupuncturists. Logistic regression was used to analyze the relationship between physical symptoms and possible correlative factors. RESULTS A total of 858 questionnaires were analyzed. The data showed that 42.42% of acupuncturists had been exposed to moxa smoke for 5-10 years. The most frequent symptom was tearing (32.98%) and the least frequent symptom was asthma (5.24%). Logistic regression analysis showed that female acupuncturists were slightly more susceptible to cough and tearing than males (cough: OR: 1.583, 95% CI: 1.079, 2.321, P = 0.019; tearing: OR: 1.519, 95% CI: 1.094,2.108, P = 0.013). Acupuncturists aged over 25 years reported a slightly lower incidence of eye itchiness than those aged under 25 years (26-40 years: OR: 0.604, 95% CI: 0.379, 0.965, P = 0.035; over 40 years: OR: 0.330, 95% CI: 0.114, 0.958, P = 0.042). Ophthalmodynia occurred less in acupuncturists aged 26-40 years (OR: 0.591, 95% CI: 0.359,0.970, P = 0.038) than in those younger than 25 years. The only association between prevalence of symptoms and tobacco use and SHS exposure was that smokers had a lower occurrence of phlegm in the throat (OR: 0.579, 95% CI: 0.392, 0.856, P = 0.006). Shortness of breath was less frequent in participants exposed to moxa smoke for more than 5 years (5-10 years: OR: 0.400, 95% CI: 0.204, 0.785, P = 0.008; 11-20 years: OR: 0.392, 95% CI: 0.178, 0.864, P = 0.02), but a slightly higher incidence of eye itchiness was found in those with over 20 years of moxa exposure (OR: 4.200, 95% CI: 1.344, 3.128, P = 0.014). CONCLUSION The most frequent symptom of moxa smoke exposure in acupuncturists was tearing. The association of symptoms with age and duration of exposure to moxa smoke were rather complicated; hence, care should be taken in drawing conclusions about the safety of moxa smoke based solely on its potentially harmful ingredients.

To explore the epidemiologic characteristics of acupuncturists who are sensitive to stimulation of moxa smoke, which could provide further direction for safety protection of exerting moxibustion and to further verify the feasibility of internet survey.A self-made questionnaire regarding body response to moxa smoke was established, which was used to conduct a face-to-face survey among acupuncturists who had performed long-term moxibustion. The Logistic regression model was used to analyze the factors affecting the stimulation response of acupuncturists and the epidemiological characteristics of acupuncturists was obtained.A total of 733 valid data was obtained. The multivariate Logistic regression analysis showed that the history of chronic respiratory disease was the main risk factor of stimulus response including cough, phlegm in the throat, asthma, dyspnea, shortness of breath and nasal dryness after exposure to moxa smoke (The stimulus response of acupuncturist after long-term exposure to moxa smoke is related to the history of chronic respiratory disease, being female, smoking or exposure of second-hand smoke, therefore more attention should be paid to those populations. In addition, the internet survey can be used for the epidemiological investigation of safety of moxa smoke.

Background Conventional moxibustion is a representative non-drug intervention in traditional Chinese medicine, and it has been reported to produce encouraging results and benefits in relieving symptoms and improving the quality of life for patients with knee osteoarthritis (KOA) in previous clinical trials and systematic reviews. Given that increasing concerns on the safety of generated smoke from conventional moxibustion have received much attention, smoke-free moxibustion is regarded as a potential alternative. However, whether smoke-free moxibustion would display a similar efficacy to that of conventional moxibustion still remains unclear. Therefore, this randomized controlled trial attempts to investigate the difference of efficacy between conventional moxibustion and smoke-free moxibustion in patients with KOA. Methods/design This is a multicenter, randomized, single-blinded, parallel-group clinical trial. A total of 138 eligible participants with KOA will be randomly allocated to two groups (conventional moxibustion group and smoke-free moxibustion group) in seven hospitals in China. Participants will receive 12 sessions of moxibustion treatment at three acupoints (EX-LE4, ST35, and ST36) over a period of 4 weeks (3 sessions per week). A smoke-removing device is placed at the top of the moxibustion device for the smoke-free moxibustion group (n = 69), while the conventional moxibustion group (n = 69) is treated with traditional moxibustion. The primary outcome measure will be the change of the global scale of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) from the baseline to 4 weeks. Secondary outcomes include the visual analog scale VASand Patient Global Assessment scores. Follow-up measurements will be performed on the 8th and 12th weeks after random allocation. Discussion This study will contribute to providing a solid foundation for the selection of moxibustion in clinical application as well as future research in moxibustion therapy.

Background Many cancer patients experience gastrointestinal adverse reaction during chemotherapy. Pharmacological interventions are commonly used to treat chemotherapy-induced gastrointestinal side effects but have various limitations. Clinical trials have indicated that moxibustion may alleviate gastrointestinal dysfunction and improve quality of life (QoL) after chemotherapy. This study aims to assess the efficacy and safety of moxibustion for chemotherapy-induced gastrointestinal adverse reaction through a systematic review and meta-analysis. Methods All randomized controlled trials (RCTs) related to moxibution targeting chemotherapy-induced gastrointestinal adverse reaction will be searched in online databases, such as PubMed, EMBASE, the Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), the Chinese Scientific Journal Database (VIP Database) and WanFang Database from their inception to May 1, 2020. The primary outcome is the incidence and severity of chemotherapy-related gastrointestinal toxicities (nausea and vomiting, diarrhea and constipation). The secondary outcomes include the quality of life, biological parameters' alteration, and adverse events. Study selection, data extraction, and assessment of risk of bias will be performed independently by 2 researchers. The Cochrane Collaboration's Review Manager (RevMan 5.3) software will be used to conduct the direct meta-analysis. Results This study will provide a comprehensive review of the available evidence for the treatment of chemotherapy-induced gastrointestinal adverse reaction with moxibustion. Conclusion The conclusion of this study will provide evidence to judge whether moxibustion is an effective and safety therapeutic intervention for chemotherapy-induced gastrointestinal adverse reaction.

Introduction Knee osteoarthritis is a common form of arthritis in elderly patients that is characterised by pain and functional limitation. Moxibustion has been employed to relieve chronic pain as an alternative therapy for knee osteoarthritis. However, the evidence of its efficacy is equivocal due to the low methodological quality in most clinical studies. Therefore, we are performing a double-blinded, double-placebo, randomised controlled trial to evaluate the efficacy of moxibustion in participants with knee osteoarthritis. Methods and analysis This is a multicentre, double-blinded, double-placebo, randomised controlled clinical trial. 144 eligible participants with knee osteoarthritis will be randomly assigned to two different groups in a 1:1 ratio. Participants in the moxibustion group will undergo active moxibustion plus placebo gel, whereas participants in the control group will receive diclofenac sodium gel plus placebo moxibustion. Each participant will receive 12 sessions of active/placebo moxibustion at three acupoints (ST35, ST36 and EX-LE4) as well as 2 months of follow-up. Diclofenac sodium gel or placebo gel at a dose of 4 g per knee will be applied three times per day for 4 weeks. The primary outcome measure will be the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score change at the end of the intervention period from baseline. The secondary outcome measures include changes of other subscales (pain, stiffness and function) of WOMAC, visual analogue scale and patient globalassessment. The safety of moxibustion and diclofenac sodium gel will be assessed at every visit. Ethics and dissemination This trial has been approved by the Sichuan Regional Ethics Review Committee (permission number: 2015KL-014). The results of this study are expected to provide clinical evidence on the efficacy of moxibustion for pain relief and physical function improvement in patients with knee osteoarthritis. The findings will be submitted for publication in peer-reviewed medical journals and presented at relevant academic conferences. Trial registration number NCT02769572.

The aim of this study was to determine whether variation of temperature during moxibustion would generate division of analgesic effect. The moxibustion with different temperatures (37°C, 42°C, 47°C, and 52°C) was applied to ST36 acupoint for 30 minutes in chronic inflammatory or neuropathic pain mice. The analgesic effect was evaluated by thermal hyperalgesia test in chronic inflammatory pain and by mechanical allodynia in neuropathic pain, respectively. The results indicated that interventions of moxibustion with different temperature caused different analgesic effect on either chronic inflammatory induced by injection of complete Freund’s adjuvant (CFA) or neuropathic pain induced by spared nerve injury (SNI). In chronic inflammatory pain, different moxibustion temperature generated different intensity of analgesic effect: the higher the better. In chronic neuropathic pain, stronger analgesic effect was found in moxibustion with temperature 47°C or 52°C other than 37°C and 42°C. However, there is no significant difference displayed between moxibustion temperatures 47°C and 52°C or 37°C and 42°C. It implies that the temperature should be taken into account for moxibustion treatment to chronic inflammatory or neuropathic pain.

One of the fundamental factors for achieving a better clinical efficacy of acupuncture therapy is to compose an appropriate acupoint recipe or a set of acupoint recipes for an illness or a clinical condition. The present article reviews recent development of researches about acupoint combination from the methods of combination style, properties and functions (synergic or antagonistic role) of different acupoints, etc., and holds that "integrity" and "nonlinear" ideas are probably the key factors for composing reasonable acupoint prescriptions. Moreover, with reference to the achievements got in the field of complex network researches of Chinese medicine, the authors discuss the applicability of studies about acupoint combination literature, and biological data integration for acupoint compatibility. The authors point out that the current complex network analysis approach may be an effective measure for understanding the regularities and mechanisms of reasonable combination of acupoints.
