OBJECTIVETo analyze medication laws of Chinese medicine (CM) treatment in hypertension patients with yin deficiency yang hyperactivity syndrome.
METHODSChina National Knowledge Infrastructure (CNKI, Jan. 1979-Dec 2014), Chinese Scientific Journals Database (VIP, Jan 1989-Dec2014), Chinese Biomedical Literature Database (CBM, Jan.1978-Dec.2014), Wanfang Database (Jan 1990-Dec 2014) were retrieved by using "hypertension", "CM", "Chinese herbs", "syndrome" as keywords. Totally 149 literatures concerning CM treatment for hypertension patients with yin deficiency yanghyperactivity syndrome were included in this study. The herbs database was established by SPSS20.0,and correlation laws were analyzed by SAS9.3. With the Pajek3.1, results were presented visually withcomplex networks.
RESULTSThere were 149 literatures including 131 kinds of herbs with 1,598 frequencies. The conventional compatibility program of herbs for asthenic yin and predominant yang syndrome of hypertension were two toothed achyranthes root, tall gastrodia rhizome, Cassia obtusifolia L., eucommiabark, baikal skullcap root, and so on, about 29 kinds. Of them, core herbs were two toothed achyranthes root, tall gastrodia rhizome, Cassia obtusifolia L., poria, prepared rhizome of rehmannia, oriental water-plantain tuber, asiatic cornelian cherry fruit, Uncariae Rhynchophylla, common yam rhizome, the rootbark of the peony tree, and so on.
CONCLUSIONMedication laws of CM treatment in hypertension patientswith yin deficiency yang hyperactivity syndrome obtained by analysis of complex networks reflected thetherapeutics of nourishing yin to suppress yang, which could further provide reference for clinical studies.

OBJECTIVETo evaluate the reliability, validity, and responsiveness of traditional Chinese medicine (TCM) clinical outcomes rating scale for heart failure (HF) based on patients' report.
METHODSTCM clinical outcomes rating scale for HF (TCM-HF-PRO) were evaluated based on 340 HF patients' report from multiple centers. The completion of the investigation was recorded. Cronbach's α coefficient and split-half reliability were used for reliability analysis, and factor analysis was used to assess the construct validity of the rating scale. Pearson correlation analysis was then used for criterion validity analysis. Discriminant analysis was used to assess the responsiveness of the scale. All 340 HF patients having complete TCM-HF-PRO data were assigned to the treatment group and the control group by central randomization. The total TCM-HF-PRO scores of the two groups were compared using paired t-test to reflect the longitude responsiveness of the scale before treatment and at week 2 after treatment.
RESULTS(1) The recycling rate of the scale was 100.0%. One of them was not filled completely, which was rejected thereby. So the completion rate was 99.7%. The completion time for TCM-HF-PRO scale ranged 15 to 25 min. (2) The Cronbach's α coefficient of rating scale was 0.903, split-half reliability was 0.844 and 0.849. (3) Confirmatory factor analysis showed that 7 factors and items formed according to maximum load factor basically coincided with the construct of the rating scale, 7 factors accumulated contribution rate was 43.8%. TCM clinical outcomes rating scale for HF based on patients' report was relatively better correlated with the Minnesota living with HF questionnaire (r = 0.726, P < 0.01). (4) Discriminant analysis showed that the rating scale correctly classified more than 78.8% of case studies having confirmed initial differential diagnosis by experts. The total scale of the rating scale decreased more in the two group after treatment, with significant difference as compared with before treatment (P < 0.01.
CONCLUSIONTCM clinical outcomes rating scale for HF based on patients' report had good reliability, validity and responsiveness, hence it could be used to assess clinical efficacy for HF patients.
