Objective To observe the effect of electroacupuncture at Baihui (GV20) and Shenting (GV24) on learning-memory function and ultrastructure in hippocampal CA1 region of rats after cerebral ischmeia-reperfusion. Methods A total of 25 male Sprague-Dawley rats were randomly divided into sham group (n=6) and operation group (n=19). The operation group was occluded the left middle cerebral arter-ies with modified Longa's methods for 90 minutes and reperfused, and twelve qualified rats of them were randomly divided into model group (n=6) and electroacupuncture group (n=6), the later accepted electroacupuncture at Baihui and Shenting for seven days. They were as-sessed with Longa's scores, and tested with Barnes maze. Their cerebral infarct volume was tested with magnetic resonance imaging T2-weighted image. The ultrastructure of synapse in hippocampal CA1 region was observed with transmission electron microscope. Results Compared with the model group, the Longa's score improved (P<0.05), the infarct volume decreased (P<0.01), the average escape latency decreased (P<0.01) and the times entering the wrong hole decreased (P<0.001) in the electroacupuncture group. Under the transmission elec-tron microscope, the number of synapse decreased in the model group, with the structure damage and vesicles sparse;compared with the model group, the number of synapse increased in the electroacupuncture group, with clear and complete structure and rich vesicles. Conclu-sion Electroacupuncture at Baihui and Shenting can improve the learning-memory function in rats after cerebral ischmeia-reperfusion, which may relate to improvement of synaptic plasticity and ameliorating ultrastructure in hippocampal CA1 region.

Objective:To investigate the effect of interleukin-33 (IL-33) on lipopolysaccharide (LPS)-induced permeability of rat cardiac microvascular endothelial cells (RCMECs).Methods:RCMECs were cultured in vitro to be divided into control group, LPS group, IL-33 group and LPS+IL-33 group. The effect of IL-33 on the proliferation of RCMECs was detected by cell counting reagent (CCK8). Fluorescein isothiocyanate (FITC)-dextran assay was used to evaluate the permeability of RCMECs. The expression of vascular endothelial calmodulin, ras homologous gene family (Rho) member A (RhoA) and phosphorylated Rho-associated coiled-coil-containing protein kinase (p-ROCK2) proteins were tested by western blot. High-throughput sequencing and gene ontology (GO) were performed for gene expression in LPS and LPS+IL-33 groups.Results:No significant effect of IL-33 at 10-50 ng/ml on the proliferation of RCMECs was observed ( P>0.05). Compared with the control group, the permeability of RCMECs (permeability coefficient ratio 1.404±0.029 vs. 1.000±0.200, P<0.05) was significantly increased in LPS group and the expression of vascular endothelial calmodulin (relative gray value 0.429 5±0.012 9 vs. 0.594 9±0.014 2, P<0.05) was down-regulated, while the permeability of monolayers (permeability coefficient ratio, 0.948±0.013, P<0.01) was decreased in LPS+IL-33 group and the expression of vascular endothelial calmodulin (relative grayscale value 0.549 1±0.012 0, P<0.005) was up-regulated compared with the LPS group. High-throughput sequencing data revealed that the differential genes downregulated in the LPS and LPS+IL-33 groups were associated with cytoskeleton and Rho signaling pathway. Compared with the control group, RhoA (relative gray value 0.211 4±0.009 9 vs. 0.135 0±0.007 6, P<0.000 1) and p-ROCK (relative gray value 0.656 3±0.013 2 vs. 0.503 6±0.036 2, P<0.000 1) protein expression was upregulated in the LPS group. When compared with LPS group, RhoA (relative gray value 0.157 7±0.010 7, P=0.000 2), p-ROCK (relative gray value 0.427 7±0.003 8, P<0.000 1) protein expression was decreased in LPS+IL-33 group. Conclusion:IL-33 may improve LPS-induced hyperpermeability of RCMECs by inhibiting RhoA and p-ROCK protein expression in Rho/Rho-associated coiled-coil-containing protein kinase signaling pathway.
