RESUMO
OBJECTIVE To establish HPLC characteristic chro matogram of Jianpi yifei biyan prescription standard decoction ， to select the quality control index components and determine their contents. METHODS HPLC method combined with Similarity Evaluation System of TCM Chromatographic Fingerprint （2004 edition）were used to establish the characteristic chromatogram of 10 batches of Jianpi yifei biyan prescription standard decoction ；the similarity evaluation and common peaks identification were also carried out. Using common peak area of characteristic chromatogram as variables ，SPSS 26.0 software and SIMCA 14.1 software were used to perfor m cluster analysis （CA），principal component analysis （PCA） and orthogonal partial least squares-discriminant analysis （OPLS-DA）；differential components with variable important i n pro jection（VIP）value greater than 1.5 were screened；the contents of cimifugin and differential components were determined by the same method. RESULTS A total of 24 common characteristic peaks were identified ， and the similarities of 10 batches of samples were higher than 0.960；eight characteristic peaks were identified by comparison with reference substance. CA and PCA results revealed that the samples were classified into 3 categories.OPLS-DA analysis showed that 3 components with VIP value greater than 1.5， which were prim-O-glucosylcimifugin （peak 2），calycosin 7-O-β-D-glucopyranoside （peak 4） and 5-O-methylvisammioside （peak 6） in descending order. The linear ranges of prim- O- glucosylcimifugin，calycosin 7-O-β-D-glucopyranoside，cimifugin and 5-O-methylvisammioside were 0.010 7-0.213 0，0.007 8- 0.156 0，0.008 0-0.160 0，0.009 8-0.195 0 μg（r＞0.999），respectively. RSD values of precision ，repeatability and stability tests （24 h） were all less than 2％. Average recoveries were 105.98％（RSD＝1.75％，n＝6），98.06％（RSD＝3.87％，n＝6），96.38％（RSD＝ 4.03％ ，n＝6） and 104.17％（RSD＝1.27％ ，n＝6）. The contents of the above 4 components in 10 batches of samples were 12.12-18.87，3.86-6.40，3.10-4.27 and 11.17-15.79 μ g/mL，respectively. CONCLUSIONS The established HPLC characteristic chromatographic method is stable and feasible ，it can be used for the quality control of Jianpi yifei biyan prescription standard decoction. Prim- O-glucosylcimifugin，calycosin 7-O-β-D-glucopyranoside，cimifugin and 5-O-methylvisammioside can be used as the index components for quality control of the standard decoction.
RESUMO
OBJECTIVE: To systematically evaluate therapeutic efficacy and safety of Compound kushen colon-release capsule versus related chemical drugs in treatment of ulcerative colitis (UC).METHODS: Retrieved from PubMed, Embase, Cochrane library, China Journal Full-text Database (CJFD), VIP, CBM and Wanfang database, RCTs about therapeutic efficacy (response rate, TCM syndrome, therapeutic efficacy of mucosal lesion) and safety (the incidence of ADR) of Compound kushen enteric-release capsule versus related chemical drugs in the treatment of UC were collected. Meta-analysis was conducted by using Rev Man 5. 3 statistical software after data extraction and quality evaluation with Cochrane 5. 1. 0. RESULTS: A total of 9 RCTs were included, involving 649 patients. The results of Meta-analysis showed that response rate [OR=2. 16, 95％CI(1. 28, 3. 63), P=0. 004] and therapeutic efficacy of mucosal lesion [OR=2. 42, 95％ CI(1. 07, 5. 47), P=0. 03] of Compound kushen colon-release capsule were significantly higher than that of chemical drugs in the treatment of UC, with statistical significance. There was no statistical significance in therapeutic efficacy of TCM syndrome [OR=1. 70, 95％CI(0. 87, 3. 32), P=0. 12] or the incidence of ADR between 2 groups. CONCLUSIONS: Therapeutic efficacy of Compound kushen colon-release capsule is better than that of related chemical drugs in the treatment of UC with similar safety.
RESUMO
OBJECTIVE:To systematically evaluate the clinical efficacy and safety of Compound Huangbo liquid combined with chemical medicine in the treatment of ulcerative colitis (UC),and to provide evidence-based reference.METHODS:Re trieved from CBM,Wanfang Database,VIP,CJFD,PubMed,EMBase and Cochrane Library,randomized controlled trials(RCTs) about Compound Huangbo liquid combined with chemical medicine (trial group) vs.chemical medicine alone (control group) in the treatment of UC were collected.Meta-analysis was performed by using Rev Man 5.3 statistical sofetware after literature scanning,data extraction and quality evaluation according to Cochrane reviewer's handbook 5.1.0.RESULTS:A total of 8 RCTs were included,involving 737 patients.The results of Meta-analysis showed that,response rate of trial group was significantly higher than that of control group,with statistical significance [OR=4.69,95 ％ CI(3.00,7.34),P＜0.001];there was no statistical significance in the incidence of ADR between 2 groups [OR=0.94,95 ％ CI (0.48,1.84),P=0.86].CONCLUSIONS:Compound Huangbo liquid combined with chemical medicine is better than chemical medicine alone for UC,and both have similar safety.

Objective To observe the effect of Changji’an Prescription (CP) on depressing the mast cells in the irritable bowel syndrome(IBS)rats. Methods The postnatal rats aged 8～21 days were given continous inflammation stimulation inside the colon to replicate the animal model of the IBS. The number of mast cells and their degranulation were observed by modified Toluidine Blue staining method under light microscope and electron microscope.
