ABSTRACT: To investigate the effects and mechanism of qi-tonifying and stasis-eliminating (QTSE) therapy on the expression of vascular endothelial growth factor (VEGF) and its receptors Flt-1 and Flk-1 in the brains of intracerebral hemorrhagic (model) rats. One hundred and eighty Sprague-Dawley rats were randomly divided into six groups: the normal group (n=5), the sham-operative (SO) group (n=35), the model group (n=35), the QTSE group (n=35), the QT group (n=35) and the SE group (n=35). All the rats except those in the normal group and SO group were established into an intracerebral hemorrhage(ICH) model by intracerebral injection of collagenase type VII and the latter three were orally administered with Buyang Huanwu Decoction (a classical recipe for QTSE) or with some of its components for qi-tonification and for stasis-elimination, respectively. To the other three groups, normal saline solutions were given instead. Behavioral tests were carried out in the animals randomly chosen from each group on days 1, 2, 4, 7, 14, 21 and 28 after modeling. The expressions of VEGF, Flk-1 and Flt-1 were determined by immunohistochemistry and the number of vascular segments with positive expression in the injured brain area of the rats was calculated. From day 7 onwards, the asymmetric forelimb use rate in the QTSE group recovered more significantly than that in the other model groups. In the model group, the expressions of VEGF, Flk-1 and Flt-1 appeared on day 1 and reached a peak on day 21, then weakened gradually. In the QTSE group, as compared with the other model groups, a higher level of VEGF expression was shown from day 7 (P<0.01) and a higher level of Flt-1 expression was shown from the 7th day to the 21st day (P<0.01). QTSE therapy can up-regulate the expressions of VEGF and its receptors (Flk-1 and Flt-1) and improve the recovery of kinetic function in the ICH rats, which may be correlated with its action in modulating vascular regeneration to promote the reconstruction of microvascular networks in the damaged areas.Chinese Journal of Integrative Medicine 12/2007; 13(4):285-90. · 0.80 Impact Factor

ABSTRACT: How to assess the therapeutic effectiveness of TCM is the focus of this paper, the trend of study on standard for therapeutic effectiveness assessment and application of standard for disease combined with symptom diagnosis and treatment were described. Taking the study on standard for TCM syndrome of Gan as an example, the basic principle and existing problem in standard formulation were pointed out. The possibility in establishing the therapeutic effectiveness assessment system of TCM by using the quantified scale for therapeutic effectiveness assessment as a tool, i.e., the theoretical design of the scale formation should be in accord with the theories of TCM, and followed with scientific measuring principle, based on the sample investigation to establish the database of quantified scale, to make sure the scale that having corresponding checking process and scoring criteria so as to make the scale meeting the need of reliability and validity. It was also pointed owt that the scale should be used in combination with the standard for syndrome differentiation, thus, the scientific, practical therapeutic effectiveness assessment system of TCM could be built up.Zhongguo Zhong xi yi jie he za zhi Zhongguo Zhongxiyi jiehe zazhi = Chinese journal of integrated traditional and Western medicine / Zhongguo Zhong xi yi jie he xue hui, Zhongguo Zhong yi yan jiu yuan zhu ban 02/2005; 25(1):72-5.
