Guidelines on common cold for Traditional Chinese Medicine based on pattern differentiation

OBJECTIVE: To establish the guidelines on common cold treated with Traditional Chinese Medicine (TCM) in terms of pattern identification. METHODS: The guidelines were formulated by using the basic patterns of common cold in ChinaPharmacopeia integrated with findings from systematic literature review and the experts' consensus on the issue in question. RESULTS: Common cold was divided into four patterns in the guidelines. The medications were recommended respectively: Ganmaoqingre granule for wind-cold exterior syndrome,Yinqiaojiedu granule for wind-heat exterior syndrome, Huoxiangzhengqi Wan for summer-heat dampness exterior syndrome and Shensu Wan for wind-cold exterior syndrome accompanied with Qi deficiency. CONCLUSION: The guidelines were primarily derived from the practice experience of TCM and the experts' consensus. The process was not strictly evidence-based because of lacking enough clinical studies. Further refinement of the guidelines should be needed as more studies are available.

Short-Term Efficacy of Treating Hepatitis B Virus-Related Acute-on-Chronic Liver Failure Based on Cold Pattern Differentiation with Hot Herbs: A Randomized Controlled Trial

Objective： To evaluate the clinical efficacy and safety of Yinchen Zhufu Decoction（茵陈术附汤, YCZFD） in the treatment of acute-on-chronic liver failure caused by hepatitis B virus（HBV-ACLF） with cold pattern in Chinese medicine（CM）. Methods： This is a multi-center randomized controlled trial of integrative treatment of CM and Western medicine（WM） for the management of HBV-ACLF patients. A total of 200 HBV-ACLF patients with cold pattern were equally randomly assigned to receive YCZFD and WM（integrative treatment） or WM conventional therapy alone respectively for 4 weeks. The primary end point was the mortality for HBV-ACLF patients. Secondary outcome measures included Model for End-Stage Liver disease（MELD） score, liver biochemical function, coagulation function and complications. Adverse events during treatment were reported. Results： The mortality was decreased 14.28% in the integrative treatment group compared with WM group（χ^2=6.156, P=0.013）. The integrative treatment was found to significantly improve the MELD score（t=2.353, P=0.020）. There were statistically significant differences in aspartate transaminase, total bilirubin, indirect bilirubin, direct bilirubin and prothrombin time between the two groups（P〈0.05 or P〈0.01）. The complications of ascites（χ^2=9.033, P=0.003） and spontaneous bacteria peritonitis（χ^2=4.194, P=0.041） were improved significantly in the integrative treatment group. No serious adverse event was reported. Conclusions： The integrative treatment of CM and WM was effective and safe for HBV-ACLF patients with cold pattern in CM. The Chinese therapeutic principle ＂treating cold pattern with hot herbs＂ remains valuable to the clinical therapy.（Trial registration No. Chi CTR-TRC-10000766）
