Comparative effectiveness of herb-partitioned moxibustion plus lifestyle modification treatment for patients with simple obesity: A study protocol for a randomized controlled trial

INTRODUCTION

Obesity is a global public health issue, which results in many health complications. Moxibustion may serve as an alternative management for simple obesity, where pharmacological therapy is always difficult to be accepted by the majority of obese patients based on its safety. However, the effects of herb-partitioned moxibustion as obesity intervention have not been confirmed. This study is designed as a single-blinded, 3-dummy randomized controlled trial to evaluate the efficacy and safety of herb-partitioned moxibustion plus lifestyle modification treatment in patients with simple obesity.

METHODS AND ANALYSIS

This study will be a randomized, controlled trial conducted from April, 2019 to April, 2021 that includes 108 participants who have simple obesity and meet the eligibility criteria. The participants will be randomly divided into 3 treatment groups: heat application group, medicated plaster group, or herb-partitioned moxibustion group. Each treatment will last 4 weeks. The primary outcomes will be the clinical effectiveness. The secondary outcome measures include participants' obesity-related indicators, the IWQOL-Lite scale, and the syndrome score of Traditional Chinese Medicine. Adverse events will be recorded during the intervention period.

ETHICS AND DISSEMINATION

Ethical approval of this study was granted by the Ethics Committee of Hubei Provincial Hospital of Traditional Chinese Medicine on 15 November 2018 (Ethics Reference No: HBZY2018-C24-01). Written informed consents will be provided by all participants before they were enrolled in this study.

Effects of herb-partitioned moxibustion for diarrhoea-predominant irritable bowel syndrome: A protocol for systematic review and meta-analysis

BACKGROUND

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common functional intestinal disease characterized by abdominal pain and diarrhea. Herb-partitioned moxibustion (HPM), a characteristic external therapy, is effective in treating IBS-D. However, no systematic review has been carried out to assess the efficacy and safety of HPM for IBS-D. The aim of this study will systematically evaluate the efficacy and safety of HPM for the treatment of patients with IBS-D.

METHODS

We will perform the comprehensive literature search in both English and Chinese electronic database including PubMed, Embase, Cochrane Library, Web of Science database, Medline, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, Wanfang database, Chongqing VIP information, and SinoMed from their inception to July 2020. All randomized controlled trials of HPM for the treatment of IBS-D will be included. RevManV5. 3 will be applied to analyze the data.

RESULTS

This study will provide high-quality synthesis of current evidence of effectiveness and safety on HPM for patients with IBS-D.

CONCLUSION

The conclusion of our systematic review will provide evidence to judge whether HPM is an effective intervention for IBS-D.

Effects of herb-partitioned moxibustion for ulcerative colitis: A protocol for systematic review and meta-analysis

BACKGROUND

Ulcerative colitis (UC) is an idiopathic, chronic inflammatory disease of the colonic mucosa. Herb-partitioned moxibustion (HPM) treatment has been demonstrated to be effective in the treatment of UC. However, there is still a lack of high-quality evidence to support the effectiveness and safety of HPM on patients with UC. This study will aim to systematically explore the efficacy of HPM for the treatment of UC.

METHODS

We will search the electronic databases of Embase, MEDLINE, PubMed, Cochrane Library Central Register of Controlled Trials, China national knowledge infrastructure database (CNKI), Wan fang database, Chongqing VIP information, and SinoMed from their inception to June 2020. Randomized controlled trials (RCTs) of HPM for the treatment of UC will be included. RevMan 5.3 software (The Nordic Cochrane Center, The Cochrane Collaboration, Copenhagen, Denmark) will be applied for statistical analysis.

RESULTS

The results of this study will be published in a peer-reviewed journal.

CONCLUSION

The conclusion of our systematic review will provide more appropriate evidence-based decisions to assist clinicians during the decision-making process when dealing with UC.

Effects of herb-partitioned moxibustion for primary dysmenorrhea: A protocol for systematic review and meta-analysis

BACKGROUND

Primary dysmenorrhea (PD) is a cyclic cramp in pelvic which affects the quality of life. Herb-partitioned moxibustion (HPM), a critical component of moxibustion therapy in traditional Chinese medicine, has been used to treat PD. However, there is still a lack of high-quality evidence to support the effectiveness and safety of HPM on patients with PD. The object of this work is to evaluate the efficacy and safety of HPM in the management of PD.

METHODS

The Embase, MEDLINE, PubMed, Cochrane Library Central Register of Controlled Trials, China national knowledge infrastructure database, Wan fang database, Chongqing VIP information, and SinoMed will be searched from their inception to Jun 2020. All randomized controlled trials of HPM for the treatment of PD will be included. We will operate article retrieval, duplication removing, screening, quality evaluation, and data analyses by RevMan 5.3 (The Cochrane Collaboration, Oxford, England).

RESULTS

This study will provide a high-quality comprehensive evaluation of the efficacy and safety of HPM for the treatment of PD.

CONCLUSION

The conclusion of our systematic review will give more convincing evidence to assist clinicians during the decision-making process when dealing with PD.

[Effect of herb-partitioned moxibustion at fanwei point on plasma motilin and serum gastrin in patients of diabetic gastroparesis]

OBJECTIVE

To explore the clinical therapeutic effect of herb-partitioned moxibustion at fanwei point in patients of diabetic gastroparesis differentiated as spleen and stomach deficiency and retention of turbid dampness as well as its effect mechanism.

METHODS

A total of 134 patients with diabetic gastroparesis were randomized into an observation group and a control group, 67 cases in each one. In the observation group, herb-partitioned moxibustion at fanwei point was adopted, 40 min each time, once a day for 5 times a week. In the control group, itopride hydrochloride tablets were prescribed for oral administration, 50 mg each time, three times a day. A total of 6 weeks of treatment was required in the two groups. Before and after treatment, the gastroparesis cardinal symptom index (GCSI) scores, 4-hour gastric emptying rate, TCM symptom score, as well as the levels of plasma motilin and serum gastrin were observed in the patients of the two groups. Additionally, the clinical therapeutic effect was evaluated in the two groups.

RESULTS

After treatment, the score of every item of GCSI, TCM symptom scores and the levels of plasma motilin and serum gastrin were all reduced as compared with those before treatment in the patients of the two groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). Regarding 4-hour gastric emptying rates, which were increased as compared with those before treatment in the two group (P<0.05), and the rate in the observation group was higher remarkably than that in the control group (P<0.05). The total effective rate was 92.5% (62/67) in the observation group, higher than 74.6% (50/67) in the control group (P<0.05).

CONCLUSION

Herb-partitioned moxibustion at fanwei point relieves the clinical symptoms in the patients with diabetic gastroparesis and increases the gastric emptying rate, which is probably related to the regulation of the levels of plasma motilin and serum gastrin.

Extracellular signal-regulated kinase, substance P and neurokinin-1 are involved in the analgesic mechanism of herb-partitioned moxibustion

Herb-partitioned moxibustion can effectively mitigate visceral pain, a major symptom in inflammatory bowel disease, but the analgesic mechanism is still unclear. Moreover, extracellular signal-regulated kinase, substance P, and neurokinin-1 are involved in formation of central hyperalgesia. Thus, we postulated that the analgesic effect of herb-partitioned moxibustion may be associated with these factors. Accordingly, in this study, we established an inflammatory bowel disease visceral pain model in rat by enema with a mixed solution of 5% trinitrobenzenesulfonic acid and 50% ethanol. Bilateral Tianshu (ST25) and Qihai (CV6) points were selected for herb-partitioned moxibustion. Our results showed that herb-partitioned moxibustion improved visceral pain and down-regulated extracellular signal-regulated kinase, substance P, and neurokinin-1 protein and mRNA expression in dorsal root ganglia. These results indicate that down-regulation of extracellular signal-regulated kinase, substance P, and neurokinin-1 protein and mRNA may be a central mechanism for the analgesic effect of herb-partitioned moxibustion.
