ObjectiveTo observe the effects of Jianpi Bushen Huoxue prescription （JPBSHX） on rat brain microvascular endothelial cells （RBMECs） based on hypoxia-inducible factor-1α （HIF-1α）/vascular endothelial growth factor （VEGF） signaling pathway， aiming to provide a theoretical basis for the treatment of ischemic stroke. MethodTwelve 8-week-old male SPF-grade SD rats were selected. Eight of them were randomly chosen and given 3.25 g·mL^-1 JPBSHX solution by gavage at a dose of 10 mL·kg^-1 for 5 consecutive days to prepare the medicated serum， which was then preserved for later use. The remaining four rats were given the same volume of normal saline. Follow-up operations were the same as those of the above eight rats. Normal rat serum was collected and stored for later use. RBMECs were revived， cultured， passaged， and randomly divided into five groups： normal group （20% normal rat serum+80% high glucose DMEM）， model group （hypoxia-reoxygenation injury） （20% normal rat serum+80% glucose-free DMEM）， medicated serum group （20% JPBSHX-medicated serum+80% glucose-free DMEM）， medicated serum+HIF-1α inhibitor group （20% JPBSHX-medicated serum+HIF-1α inhibitor 1 mg +80% glucose-free DMEM）， and medicated serum+VEGF inhibitor group （20% JPBSHX-medicated serum +VEGF inhibitor 1 mg+80% glucose-free DMEM）. The relative protein expression levels of Claudin-1 and Claudin-5 in RBMECs， the expression levels of HIF-1α and VEGF in RBMEC culture supernatants， the repair ability of RBMECs， and the number of nodes， microvessels， and their lengths after 72 h of culture were observed in each group. ResultAfter 24 h of reoxygenation， the scratch healing rate in the model group was significantly lower than in the normal group （P<0.01）. Compared with the result in the model group， the scratch healing rates significantly improved in the medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group （P<0.05）. However， the healing rates in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group were significantly lower than that in the medicated serum group （P<0.05）. The number of nodes， microvessels， and total length of microvessels in the model group were significantly lower than those in the normal group （P<0.01）. These indicators significantly improved in the medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group compared with those in the model group （P<0.05）， but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group compared with those in medicated serum group （P<0.05）. The relative expression levels of Claudin-1 and Claudin-5 proteins were significantly lower in the model group than in the normal group （P<0.01）. These levels were significantly higher in medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group than those in the model group （P<0.05）， but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group than those in the medicated serum group （P<0.05）. The expression levels of HIF-1α and VEGF in the RBMEC culture supernatants were significantly lower in the model group than those in the normal group （P<0.01）. These levels were significantly higher in the medicated serum group， medicated serum+HIF-1α inhibitor group， and medicated serum+VEGF inhibitor group than those in the model group （P<0.05）， but were significantly lower in the medicated serum+HIF-1α inhibitor group and medicated serum+VEGF inhibitor group than those in the medicated serum group （P<0.05）. ConclusionJPBSHX can promote the proliferation， migration， and angiogenesis， such as tubule formation， of RBMECs damaged by hypoxia-reoxygenation injury， and this effect may be achieved through the regulation of the HIF-1α/VEGF signaling pathway.

ObjectiveTo explore the common syndrome elements of cerebral ischemic stroke （CIS） complicated with obstructive sleep apnea-hypopnea syndrome （OSAHS）， reveal the characteristics of traditional Chinese medicine （TCM） syndromes of the disease， clarify the syndrome differentiation and syndrome types， provide evidence for clinical syndrome differentiation， and provide reference for establishing the TCM syndrome type standards of CIS complicated with OSAHS. MethodThe clinical information form of CIS complicated with OSAHS formulated by the research group was used for syndrome survey， and the four-examination information of 300 patients with CIS complicated with OSAHS was collected. The four-examination information of patients was analyzed by latent structure method and comprehensive cluster analysis， and the common syndrome elements of CIS complicated with OSAHS were extracted by combining the TCM basic theory and clinical experience. On this basis， the characteristics of TCM syndromes and the syndrome types in line with reality were summarized. ResultThe top five syndrome elements in patients with CIS and OSAHS are sleep snoring， open mouth breathing， physical obesity， night awakening and dizziness. The top five tongue and pulse manifestations are enlarged tongue， slippery pulse， slippery coating， thick and white coating and purple tongue. The disease locations are the lung， spleen， stomach， kidney， liver and brain. The nature of disease includes deficiency， depression， blood stasis， phlegm， dampness and fire. The clinical syndrome types include the syndrome of stagnation of phlegm and dampness， syndrome of phlegm-dampness blocking the mind， syndrome of spleen deficiency with dampness， syndrome of Yin deficiency leading to fire hyperactivity， syndrome of Qi depression blocking collaterals， syndrome of liver depression and blood stasis， syndrome of Qi deficiency with dampness， and syndrome of Yang deficiency induced water retention. ConclusionIn addition to the common phlegm-， dampness- and blood stasis-related syndromes in patients with CIS and OSAHS， there are also depression- and deficiency-related syndromes. The main etiology and pathogenesis is the disturbance of Qi movement. In clinical practice， attention should be paid to the specific situation of individual patients to differentiate between deficiency and excess， and the treatment should be performed by the method of soothing and reinforcing， or unblocking and clearing， or both.
