BACKGROUND: Syndrome is one of the most important concepts in Chinese medicine (CM) theory. However, it was not well accounted in most of randomized controlled trials (RCTs). OBJECTIVES: To determine whether CM syndrome differentiation affects the treatment results, functional constipation (FC) was selected as a target disease, and MaZiRenWan (, MZRW), a classic CM formula commonly used for constipation with excessive heat syndrome, was selected for study. METHODS: It is an 18-week prospective double-blinded, doubledummy RCT, including 2-week run-in, 8-week treatment and 8-week post treatment follow-up. A total of 120 FC patients diagnosed as excessive heat syndrome will be recruited from the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine and the Baokang Affiliated Hospital of Tianjin University of Traditional Chinese Medicine. Patients will be randomly allocated into fixed MZRW (f_MZRW) granule group, modified MZRW (m_MZRW) granule group or bisacodyl group. For m_MZRW group, no more than two herbal granules can be added according to the syndrome differentiation for individual participants. The primary end point is the mean of complete spontaneous bowel movements (CSBMs) per week during the treatment period. Secondary end points include mean of CSBMs per week during follow-up, stool form, global symptom improvement, constipation and constipation-related symptoms assessment, CM syndrome change, and reported adverse events. DISCUSSION This trial is designed to evaluate the effectiveness of these three interventions for FC patients with the CM syndrome of excessive heat, and to determine the change of CM syndrome and the progress of disease during the treatment course. The results are important to explore whether syndrome differentiation is important for the therapeutic effect of a formula on a disease.

This systematic review aims to systematically evaluate the efficacy and safety of Chinese patent medicines with resolving hard lump function for the treatment of cyclomastopathy. We searched CNKI, WanFang, SinoMed, PubMed, EMbase, and The Cochrane Library from the inception to January 3 2018, to collect the randomized controlled trials（RCTs）on Chinese patent medicines with resolving hard lump function in treating cyclomastopathy. Two reviewers independently screened literature, extracted data and assessed the methodological quality of included studies. Then, statistical analysis was performed by using Stata 12.0 and WinBUGS 1.4.3 software. A total of 52 RCTs involving 9 605 patients were finally included. The inventions included 11 commercial Chinese patent medicines with functions of resolving hard lump, such as Rupi Sanjie Capsules, Xiaoru Sanjie Capsules, Ruhe Sanjie Pills, and Hongjin Xiaojie Capsules. The result of direct Meta-analysis showed that: as compared with the simple western medicine group, the Chinese patent medicines such as Hongjin Xiaojie Capsules, Ruhe Sanjie Pills, Rupi Sanjie Capsules, Xiaoru Sanjie Capsules and Xiakucao Oral Liquid could significantly improve the clinical efficacy. In addition, the incidence of adverse reactions of Chinese patent medicines with resolving hard lump function was lower than that in Western medicine group in gastrointestinal reactions, menstrual disorders, leucorrhea abnormalities, liver dysfunction and estrogen-like effect. The network Meta-analysis showed that: Xiaoru Sanjie Capsules, Ruhe Sanjie Pills, Yanlu Rukang Capsules, Quyu Sanjie Capsules, and Hongjin Xiaojie Capsules were the top five in terms of treatment effect. Chinese patent medicines with resolving hard lump function had better clinical efficacy. Due to the low quality of included studies， more high quality RCTs are needed to verify the above conclusion.
