The in vitro cell culture experiment was conducted to study the effect of Danqi Piantan capsule (DPC) and DPC dislodge the antelope horn with artificial bezoar double (DPCBD) on nerve regeneration and blood vessel regeneration and preliminarily investigate the possibility of substituting antelope horn in DPC with artificial bezoar. In this experiment, rats were randomly divided into 5 groups: the blank serum control group, the model group, DPC groups (0.306 g x kg(-1) x d(-1), the same below), DPC remove of antelope horn (DPCRA) groups and DPCBD groups. Brain microvascular endothelial cells cultured in vitro (BMEC), astrocytes and neural stem cells (NSC) were co-cultured to simulate neurovascular unit, label neurons with microtubule associated protein III (β-tubulin III) antibody and lable astrocytes with glial fibrillary acidicprotein (GFAP). ELISA was used for the detection of the content of BMEC lactate dehydrogenase instrument method (LDH), the inverted phase contrastmicroscope was adopted to observe the formation of BMEC tube like structure, the number of leukocytes and leukocytes adherent to BMEC were counted under the microscope, the expression levels of β-tubulin III and the ratio of GFAP positive cells was detected with inimmunofluorescence, and RT-PCR method was used to detect NGF, BDNF, VEGF and VEGFr-2 mRNA. According to the result, compared with the model group, both DPC and DPCBD can reduce LDH leakage, promote the formation of BMEC tube like structure, inhibit leukocytes and their adhesion to BMEC, increase the β-tubulin III positive cell differentiation proportion (P < 0. 01), reduce the proportion of GFAP positive cells (P < 0.01), increase the expressions of co-cultured NGF, VEGF, BDNF and VEGFr-2 mRNA to a certain extent, with the most significant difference on NGF and VEGF mRNA expressions (P < 0.05) and the same efficacy in both groups. DPCRA groups showed less impact on all indexes than that of DPCBD and DPC groups. The same efficacy of DPCBD and DPC on nerve regeneration and angiogenesis suggested that antelope horn in DPC can be substituted by artificial bezoar.
