Scientific Evaluation of TCM Clinical Outcomes Rating Scale for Heart Failure Based on Patients Report / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate the reliability, validity, and responsiveness of traditional Chinese medicine (TCM) clinical outcomes rating scale for heart failure (HF) based on patients' report.</p><p><b>METHODS</b>TCM 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.</p><p><b>RESULTS</b>(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.</p><p><b>CONCLUSION</b>TCM 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.</p>

Expert survey for Chinese medicine syndrome characteristics of different clinical types of coronary artery disease based on the Delphi method / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To carry out expert survey for traditional Chinese medicine (TCM) syndrome characteristics of different clinical types of coronary artery disease (CAD).</p><p><b>METHODS</b>By using Delphi method, we carried out two rounds of nationwide expert surveys for modern TCM characteristics of syndrome elements and syndrome types of CAD.</p><p><b>RESULTS</b>Based on expert consensus, qi deficiency, blood stasis, phlegm turbidity, qi deficiency blood stasis, and intermingled phlegm and blood stasis are common TCM syndromes for different clinical types of CAD. Of them, qi stagnation, blood stasis, phlegm turbidity, heat accumulation, cold coagulation, yang deficiency, deficiency of both qi and yang were more often seen in patients with unstable angina than in those with stable angina. Qi deficiency, yin deficiency, and deficiency of both qi and yin were less seen. We could see more excess syndrome and less deficiency syndrome (such as qi deficiency, yin deficiency, etc.) in acute ST-segment elevation myocardial infarction (STEMI) than acute non-ST-segment elevation myocardial infarction (NSTEMI). Qi deficiency, blood stasis, water retention, yang deficiency, phlegm turbidity, yin deficiency, Xin-qi deficiency, and qi deficiency blood stasis induced water retention are the most common TCM syndrome types of CAD heart failure (HF). Blood deficiency, yin deficiency, heat accumulation, deficiency of both Xin and Pi, deficiency of both qi and blood, deficiency of both qi and yin, yin deficiency and fire hyperactivity were more often seen in CAD arrhythmias.</p><p><b>CONCLUSIONS</b>TCM syndrome distributions of different clinical types of CAD have common laws and individual characteristics. Results based on the expert consensus supplied evidence and support for clinical diagnosis and treatment of CAD.</p>

Preliminary study on the combination of the analytical hierarchy process and Delphi methods in Chinese medicine clinical research / 中国中西医结合杂志

The combination of the analytical hierarchy process (AHP) and Delphi method can overcome the strong subjectivity and poor authority in the simple use of AHP, get rid of the shackles of established thinking and take fully advantages of the experiences of experts' knowledge. By a set of quantitative calculation method, we can determine the relative importance of each factor or the relative weight of the order value, thus providing the support for clinical decision making. In this article, on the basis of the combination of AHP and Delphi method, the authors explore the Chinese medicine etiology of coronary heart disease.

Contemporary treatment of Western and Chinese medicine for cardiac syndrome X / 中国结合医学杂志

Clinical reports on cardiac syndrome X (CSX) have been increasing in recent years. In general, CSX does not increase the cardiovascular mortality, but it can affect the patient's quality of life (QOL) and increase the incidence rates of cardiovascular and cerebrovascular events. Although a variety of drugs and therapies have been utilized in the clinical treatment, the management of CSX still represents a major challenge due to its unclear pathogenesis. It is necessary to explore more effective treatment programs. Many attempts have been made on trials of the Chinese medicine (CM) treatment for CSX and proved that CM has a certain advantage in efficacy to improve clinical symptoms and QOL. CM may provide a new approach for the effective treatment of CSX.

Current status of study on impacts of Chinese herbal drugs and their preparations on pharmacokinetics / 中国中西医结合杂志

Since Chinese herbal drugs and their preparations were usually applied in combining with digoxin in modern clinical practice, high attention was accordingly widely paid to their impacts on the pharmacokinetics of digoxin. The researches in the recent years dealing with this topic were reviewed in the paper, involving the Chinese herbs, including Radix Ginseng, Radix Salviae Miltiorrhizae, Venenum Bufonis, Folium Seu Cortex Nerii Indici, St John's wort, Fructus Crataegi, and Semen Ginkgo, as well as the Chinese herbal preparations including Shengmai Injection, Milkvetch Injection, Liushen Pill, Kyushin, and Di'ao Xinxuekang, etc.
