Objective： To establish the diagnosis scale of blood stasis syndrome （BSS） and explore the idea and method of using scale to research the quantitative diagnosis of Chinese medicine （CM） syndrome. Methods： Combining the modern epidemiology, consulting the access of quality of life scale, and colligating multi-angle methods to make the scale. Results： The scale had relatively good reliability and validity and could be used to estimate the degree of stasis and analyse the curative effect. Conclusions： It was a reference for CM syndrome diagnosis that combines screening methods of scale entry with quantitative diagnosis to establish the quantitative diagnosis scale.
Objective： Compared with Shengmai Capsule （生脉胶囊, SM）, the study was conducted to evaluate the efficacy and safety of Xuefu Zhuyu Capsule （血府逐瘀胶囊, XFZY） on the symptoms and signs and health-related quality of life （HR-QOL） in the unstable angina （UA） patients with blood-stasis syndrome （BSS） after percutaneous coronary intervention （PCI）. Methods： A randomized, double-blinded, doubledummy, and placebo-controlled trial was applied. Ninety patients, diagnosed as UA and BSS after successful PCI, were enrolled and equally randomized into three groups, XFZY group, SM group, and placebo group, and administered with the corresponding medications respectively for four weeks. The clinical symptoms and signs （CSS）, electrocardiography （ECG）, and BSS scores were recorded and compared among groups during and after the treatment. Short-form 36 （SF-36） and Seattle Angina Questionnaire （SAQ） were applied to assess the HR-QOL in each group before and after the treatment. Safety indexes （blood routine and liver and kidney function tests） were also examined at the beginning and after the treatment. Results： Eighty-six patients completed the whole study. After the treatment, the total effective rates of the XFZY group in ameliorating CSS and ECG were 76.7% and 60.0%, respectively, which were obviously higher than those in SM （CSS： 53.3%; ECG： 36.7%） and the placebo （CSS： 43.3%; ECG： 30.0%） groups. After one week＇s treatment, BSS scores slightly decreased in each group, but no significant differences were found among three groups （P0.05）. After four weeks＇ treatment, BSS scores in the XFZY group decreased to a lower level compared with SM （P0.05） and the placebo （P0.01） groups. After the treatment, the efficacy of XFZY group in improving body pain （BP）, general health （GH）, vitality （VT）, society functioning （SF）, role emotional （RE）, angina stability （AS）, angina frequency （AF）, and treatment satisfaction
