Effect and Safety of Acupuncture for Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis of 21 Randomised Controlled Trials / 中国结合医学杂志

OBJECTIVE@#To evaluate the effects of acupuncture on hypoglycaemic outcomes in type 2 diabetes mellitus (T2DM).@*METHODS@#PubMed, Embase, Cochrane Library, and ClinicalTrials.gov were searched from inception up to July 2020, to identify randomised controlled trials (RCTs) that enrolled patients with T2DM and compared acupuncture combined with antidiabetic drugs to antidiabetic drugs alone. The primary outcomes were haemoglobin A1c (HbA1c) and fasting blood glucose (FBG). The secondary outcomes included 2-h blood glucose (2hBG), fasting insulin (FINS), homeostatic model assessment for insulin resistance (HOMA-IR), and acupuncture-related adverse events. Mean difference (MD) and 95% confidence interval (CI) were used as the effect measure in the meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation tool.@*RESULTS@#Twenty-one RCTs (n=1,188) were included. The meta-analytic results showed that the acupuncture group had greater reductions in FBG (MD -6.46 mg/dL, 95% CI -11.95 to -0.98; moderate-quality evidence) and HOMA-IR (MD -1.23, 95% CI -2.16 to -0.31; low-quality evidence), but comparable changes in HbA1c (MD -0.39%, 95% CI -0.84 to 1.61; very-low-quality evidence), 2hBG (MD -4.99 mg/dL, 95% CI -20.74 to 10.76; low-quality evidence), and FINS (MD -1.32 µIU/mL, 95% CI -3.76 to 1.12; low-quality evidence). No data on the incidence of diabetic complications were found. All acupuncture-related adverse events reported were mild.@*CONCLUSIONS@#The current evidence suggests that acupuncture, as a complementary therapy to antidiabetic drugs, has a small but statistically significant effect on decreasing FBG and improving insulin resistance. The effects of acupuncture on HbA1c, 2hBG, and FINS remain uncertain. Acupuncture is generally safe in patients with mild diabetes. More evidence for the long-term effects of acupuncture on T2DM is needed. (Trial registration No. CRD42018115639).

Technical recommendations for pragmatic randomized controlled trials of heat-sensitive moxibustion in community (Ⅱ): organization, implementation and follow-up visits / 中国针灸

Based on the community research experience of heat-sensitive moxibustion, this study explained technical recommendations for pragmatic randomized controlled trials (pRCTs) of heat-sensitive moxibustion in community from 7 aspects: selection of community research sites, ethical approval and registration, patient recruitment, training of standard operating procedures, ensuring patient compliance, quality control of follow-up visits and patient safety, which aimed to reduce the difficulty of research execution and improve the quality of pRCTs implementation and follow-up visits of heat-sensitive moxibustion.

Technical recommendation for pragmatic randomized controlled trial of heat-sensitive moxibustion in community (Ⅰ): randomization with consideration of patient preference / 中国针灸

Heat-sensitive moxibustion is the appropriate technique of the external treatment in traditional Chinese medicine and it is widely used in community because of its "easy learning, simple operation and clear curative effect". Pragmatic randomized controlled trial is a main intervention design in the real world study, which provides a high-level evidence for the effectiveness assessment of heat-sensitive moxibustion in community management. Focusing on the key links of randomization, e.g. block randomization, stratified randomization, cluster randomization, sample size allocation, allocation concealment and blinding, the paper elaborates the advantages, disadvantages and technical details of two-stage randomization with consideration of patient preference in pragmatic randomized controlled trials of heat-sensitive moxibustion in community. It facilitates improving the quality of evidence, reproducibility and methodological homogeneity among different trials.
