Effect of qi-tonifying and stasis-eliminating therapy (益气活血法) on expression of vascular endothelial growth factor and its receptors Flt-1, Flk-1 in the brain of intracerebral hemorrhagic rats
摘要
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 (补阳还五汤
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

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.
