The identification of eligible controlled trials for systematic reviews of complementary and alternative medicine (CAM) interventions can be difficult. To increase access to these difficult to locate trials, the Cochrane Collaboration Complementary Medicine Field (CAM Field) has established a specialized register of citations of CAM controlled trials. The objective of this study is to describe the sources and characteristics of citations included in the CAM Field specialized register.

Background: Moxibustion, acupuncture and other acupoint stimulations are commonly used for the correction of breech presentation. This systematic review aims to evaluate the efficacy and safety of moxibustion and other acupoint stimulations to treat breech presentation. Methods: We included randomized controlled trials (RCTs) and controlled clinical trials (CCTs) on moxibustion, acupuncture or any other acupoint stimulating methods for breech presentation in pregnant women. All searches in PubMed, the Cochrane Library (2008 Issue 2), China National Knowledge Information (CNKI), Chinese Scientific Journal Database (VIP) and WanFang Database ended in July 2008. Two authors extracted and analyzed the data independently. Results: Ten RCTs involving 2090 participants and seven CCTs involving 1409 participants were included in the present study. Meta-analysis showed significant differences between moxibustion and no treatment (RR 1.35, 95% CI 1.20 to 1.51; 3 RCTs). Comparison between moxibustion and knee-chest position did not show significant differences (RR 1.30, 95% CI 0.95 to 1.79; 3 RCTs). Moxibustion plus other therapeutic methods showed significant beneficial effects (RR 1.36, 95% CI 1.21 to 1.54; 2 RCTs). Laser stimulation was more effective than assuming the knee-chest position plus pelvis rotating. Moxibustion was more effective than no treatment (RR 1.29, 95% CI 1.17 to 1.42; 2 CCTs) but was not more effective than the knee-chest position treatment (RR 1.22, 95% CI 1.11 to 1.34; 2 CCTs). Laser stimulation at Zhiyin (BL67) was more effective than the knee-chest position treatment (RR 1.30, 95% CI 1.10 to 1.54; 2 CCTs,). Conclusion: Moxibustion, acupuncture and laser acupoint stimulation tend to be effective in the correction of breech presentation.

Background Evidence-based medicine promotes and relies on the use of evidence in developing clinical practice guidelines (CPGs). The Chinese healthcare system includes both traditional Chinese medicine (TCM) and Western medicine, which are expected to be equally reflected in Chinese CPGs. Objective To evaluate the inclusion of TCM-related information in Western medicine CPGs developed in China and the adoption of high level evidence. Methods All CPGs were identified from the China Guideline Clearinghouse (CGC), which is the main Chinese organisation maintaining the guidelines issued by the Ministry of Health of China, the Chinese Medical Association and the Chinese Medical Doctors’ Association. TCM-related contents were extracted from all the CPGs identified. Extracted information comprised the institution issuing the guideline, date of issue, disease, recommendations relating to TCM, evidence level of the recommended content and references supporting the recommendations. Results A total of 604 CPGs were identified, only a small number of which (74/604; 12%) recommended TCM therapy and only five guidelines (7%) had applied evidence grading. The 74 CPGs involved 13 disease systems according to the International Classification of Diseases 10th edition. TCM was mainly recommended in the treatment part of the guidelines (73/74, 99%), and more than half of the recommendations (43/74, 58%) were related to Chinese herbal medicine (single herbs or herbal treatment based on syndrome differentiation). Conclusions Few Chinese Western medicine CPGs recommend TCM therapies and very few provide evidence grading for the TCM recommendation. We suggest that future guideline development should be based on systematic searches for evidence to support CPG recommendations and involve a multidisciplinary approach including TCM expertise.

Purpose: Trial participation and adherence to interventions can directly influence the evaluation of outcomes in clinical trials for real world applications. The factors that influence trial participation and adherence to Tai Chi interventions in people with cardiovascular diseases remains unknown. This study aimed to explore participants’ perceptions of influential factors on their trial participation and adherence to a Tai Chi intervention within a trial setting. Patients and Methods: Participants had coronary heart disease and/or hypertension in a randomized controlled trial comparing Tai Chi with a waitlist control. Data were collected via face-to-face, semi-structured interviews and analyzed using thematic analysis. Results: Thirty-four participants from the Tai Chi group who completed the randomized trial were interviewed. Six dominating themes and four sub-themes are discussed under the facilitators of internal and external motivation, positive feelings, benefits of Tai Chi and future practice with an overall internal motivation to improve health. Positive feelings had three sub-themes: positive feelings toward Tai Chi, the project, and the learning experience. The Tai Chi instructor(s) was found to be a crucial element in motivating participants’ adherence to Tai Chi. Conclusion: From the perception of participants, the facilitators to their trial participation and adherence to a Tai Chi intervention included internal and external motivation, positive feelings towards Tai Chi, the project and the learning experience, and perceived benefits of Tai Chi. Perceived barriers included concerns about the safety and complexity of Tai Chi practice, lack of group atmosphere outside of class, and scheduling conflicts. Future researchers can address these factors to improve trial recruitment and implementation of Tai Chi and other mind-body interventions in research and for real world applications.

The purpose of this systematic review (SR) is to evaluate the effectiveness and safety of Tui Na therapy for insomnia. Two authors separately searched PubMed, the Cochrane Library, EMBASE, SinoMed Database, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Science Technology Journal Database, related SR and published protocols at the same time to find randomized controlled trials (RCTs), which compared Tui Na therapy with estazolam therapy for insomnia, from their inception to January^1st 2019. Screening documents, data extraction, quality assessment of methodology and quality assessment of evidence were also conducted by two authors separately at the same time. We used Cochrane Risk of Bias tool to assess the methodological quality of included RCTs. The results of meta-analysis were made via RevMan software (5.3). The quality of evidence was assessed by on-line GRADEpro. The primary outcome: Pittsburgh Sleep Quality Index (PSQI) score, the secondary outcome: clinical effectiveness rate and the safety index: adverse events. The clinical effectiveness of these included RCTs all focused on the improvement of patients' satisfaction with sleep time and sleep quality. We included 22 RCTs(1,999 participants), meeting the inclusion and exclusion criteria. The assessment of methodological quality was not satisfied, in which "high risk", "unclear risk" and "low risk" all existed. The results of meta-analysis demonstrated that (1)for primary outcome, the PSQI score of Tui Na therapy was lower than that of estazolam therapy after treatment in subgroup1(Head)(MD-2.39,95%CI[-3.79,-0.98],I² = 82%,n = 291,3 trials) and subgroup4(Abdomen)(MD-1.7,95%CI[-2.53,-0.87],I² = 0%,n = 120,2 trials);while there was no significant difference between Tui Na therapy and estazolam therapy in subgroup2(Head and trunk)(MD-1.39,95%CI[-3.03,0.24],I² = 90%,n = 200, 2 trials) and subgroup3(Head, trunk and extremities)(MD-0.51,95%CI[-1.53,0.5],I² = 30%,n = 126,2 trials).(2) for secondary outcomes(the clinical effectiveness rate and safety index),the clinical effectiveness rate of Tui Na therapy was higher than that of estazolam therapy after treatment in subgroup1(Head)(RR1.21,95%CI[1.05,1.39],I² = 26%,n = 239,3 trials), subgroup2(Head and trunk)(RR1.15,95%CI[1.08,1.23],I² = 33%,n = 1024,10 trials) and subgroup4(Abdomen)(RR1.12,95%CI[1.01,1.23],I² = 0%,n = 180,3 trials); while there was no significant difference between Tui Na therapy and estazolam therapy in subgroup3(Head, trunk and extremities)(RR1.03,95%CI[0.94,1.13],I² = 28%,n = 346,4 trials).Safety index, 5 RCTs reported adverse events. Among them, only 1 RCT reported adverse event in Tui Na therapy, which was daytime drowsiness; all 5 RCTs reported adverse events in estazolam therapy, which were dry mouth, dizziness, daytime drowsiness etc. The evidence quality was generally low to very low. Tui Na therapy appeared to be superior to estazolam therapy in treating areas(head; abdomen), while there was no significant difference between Tui Na therapy and estazolam therapy in treating areas(head and trunk; head, trunk and extremities). No serious adverse event was reported in Tui Na therapy. However the methodological quality and evidence quality were not satisfied. Therefore we could not make a convincing conclusion on the effectiveness and safety of Tui Na therapy for insomnia. Practitioners should combine their experience, evidence of our review and patients' preferences to make a proper treatment. And more high quality RCTs and well-designed protocols of Tui Na therapy for insomnia are needed in the future.
