Establishment and initial evaluation of health scale of traditional Chinese medicine / 中国中西医结合杂志

Viewing from some TCM concepts and basic characteristics of health, assimilating the operationalization concerning thinking and procedure of modern scientific research, the pilot form of Health Scale of TCM--initial health scale of TCM (iHSTCM) based upon TCM theory was developed. From November 2002 to January 2003, the domain, facets and items of HSTCM were finally established by analyzing the data from a survey of 652 persons in Guangzhou City using iHSTCM. In conclusion, the HSTCM has its theoretical ratio-nality and is applicable. It could be further applied in TCM clinical practice.

Application of non-randomized study in the field of traditional Chinese medicine or integrated traditional Chinese and Western medicine / 中国中西医结合杂志

Non-randomized studies (NRS) have gradually attracted people's attention in the field of clinical medicine. In this paper, the importance of NRS was emphasized on the viewpoints of the coherence of scientific research, the limitation of randomized control trials (RCTs), the immanent characteristics of TCM clinical practice and the actual requirement of complex intervention in clinical practice. And two main points in evaluation and implementation of NRS differed to those in RCTs were put forward, i.e. the first, the full-scale design of the study with the professional characteristics should be described very explicitly, especially the speciality of the objects, intervention elements and indexes for effectiveness evaluation, etc.; the second, the control of bias and evaluation of effectiveness, and their influence on conclusion induction should be fully taken into consideration. At the same time, the key step in improving the quality of NRS of TCM and integrative medicine was preliminary discussed in this paper.

Exploration on establishment and application of soft index survey tools in TCM study / 中国中西医结合杂志

It was pointed out that there was broad space for application of SIST in TCM study.

How to analyze and interpret the effective values in clinical trials / 中国中西医结合杂志

The analysis of the effective value obtained in clinical trails should take account of both sides of its size and precision, for its interpretation, the general principles of: accuracy, explicitness and quantification should be complied. Criteria such as relative risk (RR), relative risk reducing rate (RRR), absolute risk reducing rate (ARR) and number needed to treat (NNT) an important clinical event, etc. are commonly used in the primary outcomes interpretation, while the methods to express the effective size and precision of surrogate outcomes and intermediary outcomes are needed to be further studied. Many problems for give expression to the outcome of TCM clinical trail still remain to be solved.

General contemplation on causality in appraising clinical efficacy of traditional Chinese medicine / 中国中西医结合杂志

This paper briefly introduced the general principles for causality in scientific researches and clinical studies, addressed the importance of population-based approaches in it, and also reviewed the developing course and presented the elementary requirements of randomized controlled trials (RCTs). The author identified with views that as compared with the research design of other types, RCTs is the most authentic one in the aspect of causality of efficacy and intervention. It is stressed that a causal inference for the efficacy assessment of traditional Chinese medicine (TCM) must meet the nomothetic criteria. The author emphasized that the scientific merits of RCTs are not only for assessing the efficacy of conventional treatments, but also for TCM intervention owing to RCTs yield stronger inferences about therapeutic intervention than other study designs, which are wildly accepted by academic communities.

Exploration on the basic framework of standard for macrocosmic diagnosis of syndrome / 中国中西医结合杂志

Starting from the thinking characteristics of TCM in the holistic approach of syndrome and process of syndrome differentiation, the problems in the criteria of syndrome diagnosis was analyzed, combining with the outcome of investigation on macrocosmic diagnosis of syndrome carried on twice by expert group nationwide in China, a concept for designing basic framework of standard for macrocosmic diagnosis of syndrome was advocated in this study. In order to recognize and master fully the standard, the following items would be the contents of the framework: give a standardized term of each syndrome; the basic clinical features of a syndrome; the qualitative parameters which could be used to distinguish the nature of a syndrome, and indexes to be used to judge the affected location of a syndrome during identifying process for a syndrome; the order of pertinent indexes with their given score, and the threshold for quantitative diagnosis. It is considered that the above framework defined the sufficient criteria which is constructed on the bases of the approaches with integrated qualitative and quantitative methods. It may enable the syndrome differentiation to access the real world of a patient to be used appropriately this framework.

Surrogate outcomes, intermediary outcomes and their application in TCM clinical efficacy evaluation / 中国中西医结合杂志

In this paper, the concepts of surrogate outcomes and intermediary outcomes, their correlation with the primary outcome, how to select surrogate outcomes and intermediary outcomes and the particular requirements for using surrogate outcomes in assessing TCM clinical efficacy were discussed and described. It is difficult to evaluate clinical efficacy objectively and thoroughly by means of a single surrogate outcome for reason of the global characteristics of TCM, therefore, to rationally select such intermediary outcomes as important clinical symptoms, combination of several syndromes, patients' subject feeling, patients' satisfaction for treatment and quality of life, should be beneficial for objectively evaluating the efficacy of TCM intervention approaches.

Preliminary study on outcome assessment system of treatment of stroke / 中国中西医结合杂志

<p><b>OBJECTIVE</b>In order to scientifically reflect the real efficacy of TCM treatment and to preliminarily establish a definitely valid and reliable assessment system of stroke treatment, with multi-dimensional outcome assessment indexes, including efficacy evaluation system of conventional western medicine, syndrome evaluation criteria in TCM and quality of life assessment system.</p><p><b>METHODS</b>An integrative approach of cross-sectional survey and prospective follow-up was adopted. Two hundred and forty-five case-episodes of stroke patients were assessed by determining such parameters as nerve functional deficit scale, grading of total status of living ability, activity of daily living (ADL), TCM stroke criteria of diagnosing-treatment, TCM syndrome related symptoms/signs, Health Survey Questionnaire (Short form 36, SF-36), and index of quality of life (QOL), and their construction and relation were analyzed by such methods as multivariate relation, partial relation, linear regression, factor analysis, Cronbach's alpha coefficients, and the responsiveness estimation.</p><p><b>RESULTS</b>The multi-dimensional assessment system of stroke treatment, containing 57 indexes with clarified constructions and classification, was created, and its validity and reliability confirmed after assessement. Various degrees of relationship were found between different TCM Syndromes and different domains of QOL.</p><p><b>CONCLUSION</b>The assessment system of stroke treatment preliminarily created has satisfied reliability and validity. It could be expected to reflect the real efficacy of TCM treatment more inclusive and accurate. TCM Syndrome indexes are considered to be the factor related to both domains of mental and physical health, particularly with the former, therefore, to improve the TCM Syndrome would imply improvement of the mental health, physical health and QOL of the patients.</p>
