ABSTRACT
Objective: To explore effect of modified Guifu Dihuang Wan (Wenshen Huoxue Fang) on life quality in patients with coronary hear disease (CHD) after percutaneous coronary intervention (PCI) and evaluate the safety of its clinical use. Method: The 147 postoperative patients with PCI in Chongqing Traditional Chinese Medicine Hospital cardiology outpatient and the inpatient departments between June 2017 to May 2018 were selected and randomly divided into the treatment group and control group by random even and odd number. The patients in control group took the basic treatment (western medicine), and the patients in the treatment group additionally received modified Guifu Dihuang Wan based on the treatment in control group, with a course of 4 weeks in both groups. Minnesota Living with Heart Failure Questionnaire (MLHFQ) total score, 6 minutes walk test (6 mWT), Seattle Angina Scale (SAQ) score, and traditional Chinese medicine(TCM) syndrome score were recorded and compared between two groups before and after treatment; their cardiac function was evaluated and adverse reactions were observed to assess the drug safety and quality of life after PCI. Result: The MLHFQ scores in treatment group after treatment were significantly lower than those before treatment and those in control groups after treatment (PPPPPConclusion: On the basis of conventional western medicine therapy, the modified Guifu Dihuang Wan can effectively improve the physical strength, mood, TCM symptoms, relieve angina pectoris, and enhance cardiac function with no adverse reactions in PCI postoperative patients. It can achieve the purpose of improving quality of life in postoperative patients, worthy of promotion.
ABSTRACT
Objective To find a new method for quality control of polysaccharides by establishing the fingerprint profiles of polysaccharides extracted from Guifu Dihuang Wan. Methods The polysaccharides extracted from Guifu Dihuang Wan were hydro-lyzed partially under appropriate hydrolysis condition with acid,and the fingerprint profiles of the hydrolyzates was obtained by HPLC. Microsoft Excel 2002 was applied for calculating the similarity of fingerprint profiles,and informatton analysis of these profiles was performed by a software for evaluating fingerprint profiles of traditional Chinese medicine. Results Fingerprint profiles of the hydroly-zates of polysaccharides from 10 of Guifu Dihuang Wan products,produced by different manufacturers,were obtained. It was observed that the similarity of eight products was greater than 0.99,while the similarity of the other two was 0.92 and 0.94,respectively. Con-clusion This method is technically feasible for the quality control of polysaccharides from Guifu Dihuang Wan.
