Objective: To assess the clinical evidence for and against acupuncture as a treatment for Bell's palsy. Methods: We conducted a literature search of 15 databases from their inception to December 2010 without language restrictions. We included all randomized clinical trials (RCTs) regardless of their controls. Methodological quality was evaluated using the Cochrane risk of bias assessment tool. Results: Of the 3 474 articles, only eight RCTs met our inclusion criteria. Four RCTs tested the effects of acupuncture against drug therapy on disease response rate. The meta-analysis of these data showed significant improvements in the acupuncture group [n=463, risk ratio (RR)=1.07, 95% CI: 1.02 to 1.13; P=0.006, I^2=0%]. Six RCTs tested the effects of acupuncture plus drug therapy versus drug therapy alone. The meta-analysis of this set of RCTs also showed the favorable effects of acupuncture on disease response rate (n=512, RR=1.11, 95% CI: 1.05 to 1.17; P=0.001, I^2=13%). Conclusions: The evidence supporting the effectiveness of acupuncture for treating Bell's palsy is limited. The number and quality of trials are too low to form firm conclusions. Further rigorous RCTs are warranted but need to overcome the many limitations of the current evidence. 展开更多

Objective:To assess the effectiveness of acupuncture as a treatment option for attention deficit hyperactivity disorder(ADHD).Methods:The literatures were searched using 15 databases,including MEDLINE, AMED,CINAHL,EMBASE,Psyclnfo,the Cochrane Central Register of Controlled Trials,the Cochrane Database of Systematic Reviews,six Korean medical databases and two Chinese databases without language restritions.Prospective controlled clinical studies of any type of acupuncture therapy for ADHD autistic patients were included.Trials in which acupuncture was part of a complex intervention were also included.All articles were read by two independent reviewers,who extracted data from the articles according to predefined criteria. Risk of bias was assessed using the Cochrane risk of bias tool.Results:Of 114 articles,only three randomized clinical trials(RCTs) met our inclusion criteria.One RCT found that electroacupuncture(EA) plus behavioural treatment was superior to sham EA plus behavioural treatment.Two RCTs reported a significant benefit of acupuncture or auricular acupuncture over conventional drug therapies.Conclusions:Limited evidence exists for the effectiveness of acupuncture as a symptomatic treatment of ADHD.Given that the risk of bias of the included studies was high,firm conclusions cannot be drawn. 展开更多

Objective: Tai chi has been recommended for treating type 2 diabetes mellitus. The purpose of this systematic review was to evaluate evidence from controlled clinical trials testing the effectiveness of tai chi in treating type 2 diabetes mellitus. Methods: Systematic searches were conducted on 14 electronic databases without restrictions on either population characteristics or language of publication. The outcome measures considered for inclusion were changes in fasting blood glucose (FBG), glycosylated haemoglobin A1c (HbA1c) and quality of life (QOL). Results: Eight randomised clinical trials (RCTs) and two controlled clinical trials (CCTs) met all inclusion criteria. Three RCTs from 1 trial compared the effects of tai chi with sham exercise and failed to show effectiveness of tai chi on FBG, HbA1c, or QOL. The other 3 RCTs tested the effects of tai chi compared with other types of exercise on FBG. The meta-analysis failed to show an FBG-lowering effect of tai chi [n=118, weighted mean difference (WMD): -0.14 mmol/L, 95% CI:-0.86 to 0.58,P=0.70]. Four studies (2 RCTs and 2 CCT) compared tai chi with no treatment or self-management programme and failed to report significant differences between the experimental and control groups except for QOL from 1 RCT and 1 CCT. Conclusion: The existing evidence does not suggest that tai chi is an effective therapy for type 2 diabetes. Currently, there are few high-quality trials on which to make definitive judgements. 展开更多

Objective: To study various experts’ opinions on the definition and diagnosis of blood stasis in China. Methods: We e-mailed the selected experts to explain the purpose of the study and to invite them to participate and asked them to name a time for the investigator to call them. Eight experts and five organizations were interviewed in the research community investigating blood stasis in China. Results: Six main categories emerged from the interviews:(1) blood stasis concepts;(2) blood stasis-related biomarkers;(3) methods of diagnosing blood stasis;(4) drugs for promoting blood circulation and dissipating stasis;(5) blood stasis-related diseases; and(6) blood stasis-related societies. The consensus among the interviewed experts was that the definition of blood stasis is rather complicated and that there is no gold standard marker for detecting blood stasis. Conclusion: This paper acquired experts’ opinions on the definition and diagnosis of blood stasis in order to establish a modern concept of blood stasis. This paper also developed a diagnostic tool and diagnostic indices for blood stasis and identified biological indices and pathologic mechanisms related to blood stasis, which might be of great reference value in future blood stasis standardization research. 展开更多

Objective: To evaluate the effectiveness of Chuna for the treatment of musculoskeletal pain as reported in Korean literature. Methods: We conducted an electronic literature search using seven Korean databases and manually searched six traditional Korean medicine journals. Risk of bias was assessed with the Cochrane criteria. Results: Six randomized controlled trials (RCTs) were included in the study. Compared with standard care, three RCTs suggested favorable effects of Chuna on neck pain due to a hypolordotic cervical spine, low back pain caused by traffic accidents, and low back pain. In contrast, compared with standard care, three RCTs failed to show positive effects on temporomandibular joint disorder, mandibular movement, and neck pain caused by traffic accidents. Conclusions: Currently, the evidence of the effectiveness of Chuna for the treatment of musculoskeletal pain is not convincing. Further rigorously designed trials are warranted to determine its effectiveness. 展开更多

Objective:To summarize and critically evaluate the evidence for and against the effectiveness of Eastern-Western integrative medicine(EWIM) for health care compared to Eastern medicine(EM) or Western medicine(WM) alone.Methods:Systematic searches were conducted on five Korean medical databases.Manual searches were also conducted through nine major Korean medical journals.Prospective randomized clinical trials (RCTs) were included if EWIM was tested for any type of conditions compared to EM or WM.Results:There were one hundred forty-one possibly relevant studies were identified,and seven RCTs were included.The risk of bias was high in most studies.The EWIM methods were compared with EM or WM in patients with pain conditions in four studies.These studies showed favorable effects of EWIM on pain reduction in patients with shoulder pain and chronic headache compared with EM,while the other RCTs failed to do so in traffic injury patients.Two studies tested EWIM in patients with Bell's palsy compared with EM and found acute functional improvement.An RCT comparing EWIM with WM in patients with acne showed a significant difference.Conclusion:The results of our systematic review suggest that there is limited evidence for the superiority of EWIM over EM or WM in the treatment of pain and acute symptom improvement in patients with Bell's palsy.The evidence from our analysis was limited from the low number of RCTs included and the high risk of bias.Future RCTs appear to be warranted. 展开更多
