METHODS: LPS was continuously infused through the jugular artery of male Wistar rats at the dose of 2 mg/kg per hour. Changes in mesenteric microcirculation,such as diameters of arterioles and venules,velocity of RBCs in venules,leukocyte rolling,adhesion and emigration,free radicals released from post-capillary venules,FITC- albumin leakage and mast cell degranulation,were observed through an inverted intravital microscope assisted with CCD camera and SIT camera. Meanwhile,the expression of adhesion molecules CD11b/CD18 and the production of free radical in neutrophils,and the expression of intercellular adhesion molecule 1 (ICAM-1) in human umbilical vein endothelial cells (HUVECs) were quantified by flow cytometry (FACS) in vitro. RESULTS: The continuous infusion with LPS resulted in a number of responses in microcirculation,including a significant increase in the positive region of venulestained with Monastral blue B,rolling and adhesion of leukocytes,production of oxygen radical in venular wall,albumin efflux and enhanced mast cell degranulation in vivo,all of which,except for the leukocyte rolling,were attenuated by the treatment with compound Danshen injection. Experiments performed in vitro further revealed that the expression of CD11b/CD18 and the production of oxygen free radical in neutrophils,and the expression of ICAM-1 in HUVECs were increased by exposure to LPS,and they were attenuated by compound Danshen injection. CONCLUSION: These results suggest that compound Danshen injection is an efficient drug with multi-targeting potential for improving the microcirculatory disturbance.展开更多

In another set of experiments, R1 was continuously infused (10 mg/kg per hour) from 10 min before I/R until the end of the investigation to study the influence of R1 on hepatic microcirculatory disturbance induced by gut I/R. Hepatic microcirculation was observed by inverted microscopy, and the vascular diameter, red blood cell (RBC) velocity and sinusoid perfusion were estimated. Leukocyte rolling and adhesion were observed under a laser confocal microscope. Thirty and 60 min after reperfusion, lactate dehydrogenase (LDH), alanine aminotransferase (ALT) and aspartate transaminase (AST) in peripheral blood were determined. The expression of adhesion molecules CD11b/CD18 in neutrophils and tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and monocyte chemotactic protein-1 (MCP-1) in plasma were evaluated by flow cytometry. E-selectin and intercellular adhesion molecule-1 (ICAM-1) in hepatic tissue were examined by immunofluorescence. RESULTS: After gut I/R, the diameters of terminal portal venules and central veins, RBC velocity and the number of perfused sinusoids were decreased, while the leukocyte rolling and adhesion, the expression of E-selectin in hepatic vessels and CD18 in neutrophils, IL-6, MCP-1, LDH, ALT and AST were increased. R1 treatment attenuated these alterations except for IL-6 and MCP-1.CONCLUSION: R1 prevents I/R-induced hepatic microcirculation disturbance and hepatocyte injury. The effect of R1 is related to its inhibition of leukocyte rolling and adhesion by inhibiting the expression of E-selectin in endothelium and CD18 in neutrophils.展开更多

The pathology of subarachnoid hemorrhage likely involves major morphological changes in the microcirculation. However, previous studies primarily used fixed tissue or delayed injury models. Therefore, in the present study, we used in vivo imaging to observe the dynamic changes in cerebral microcirculation after subarachnoid hemorrhage. Subarachnoid hemorrhage was induced by perforation of the bifurcation of the middle cerebral and anterior cerebral arteries in male C57/BL6 mice. The diameter of pial arterioles and venules was measured by in vivo fluorescence microscopy at different time points within 180 minutes after subarachnoid hemorrhage. Cerebral blood flow was examined and leukocyte adhesion/albumin extravasation was determined at different time points before and after subarachnoid hemorrhage. Cerebral pial microcirculation was abnormal and cerebral blood flow was reduced after subarachnoid hemorrhage. Acute vasoconstriction occurred predominantly in the arterioles instead of the venules. A progressive increase in the number of adherent leukocytes in venules and substantial albumin extravasation were observed between 10 and 180 minutes after subarachnoid hemorrhage. These results show that major changes in microcirculation occur in the early stage of subarachnoid hemorrhage. Our findings may promote the development of novel therapeutic strategies for the early treatment of subarachnoid hemorrhage.展开更多

These cardi...Acute coronary syndrome, stroke and other ischemic events continue to be the most common causes of mortality and morbidity in the world, and their incidence is rapidly increasing in the developing nations. These cardiovascular disorders clinically manifest as acute atherothrombotic events. Application of oral antiplatelet drugs is a milestone in the therapy of cardiovascular diseases. However, the limited efficacy of these drugs in the setting of arterial thrombosis, their unfavorable side effects, cost-to-benefit issues and the drug resistance phenomenon substantiate the need for the development of new and more efficacious antithrombotic drugs. In recent years, with the progress in the study of the Chinese medicine pharmacology, many Chinese herbs and formulas, as well as active constituents have been reported to possess not only effects on platelet aggregation and activation but also beneficial roles in vascular functions. Compared with currently used antithrombotic agents, herb remedies exert antithrombotic effects in a multi-pathway and multi-target manner. This paper will cover the progress in research on the ameliorating effects of herbal remedies on thrombosis, with focusing on their protection of vascular endothelial cells and inhibition of platelet activation.展开更多

Endotoximia model was conducted by continuous LPS infusion. Changes in mesenteric microcirculatory variables, including diameter of venule, velocity of red blood cells in venule, leukocyte adhesion, free radicals produced in venule and albumin leakage from venule, were observed through an inverted intravital microscope. Meanwhile, the expression of myeloperoxidase(MPO), CD18,intercellular adhesion molecule-1(ICAM-1), toll-like receptor 4(TLR4), nuclear factor-kappa B p65 subunit(NF-κB p65), activator protein-1(AP-1), and Jun N-terminal kinase(JNK) was assessed by Western blot.Results: After infusion of LPS, the number of leukocytes adherent to venular wall, the intensity of dihydrorhodamine 123(DHR)fluorescence in the venular walls, and albumin leakage from venules were significantly increased, whereas the red blood cell velocity in venule was decreased. All the manifestations were significantly reduced by pre-treatment and post-treatment with paeonol. Moreover, paeonol significantly attenuated the expression of MPO, CD18, ICAM-1, TLR4, NF-κB p65, AP-1 and JNK in rat mesentery after LPS.Conclusions: The results demonstrated that paeonol could protect from and ameliorate the microcirculation disturbance induced by LPS.展开更多

PNS(5 mg/kg/hr) was continuously administrated starting from 10 min before ischemia or 10 min after reperfusion until60 min after reperfusion via left jugular vein. Leukocytes adhesion, mast cell degranulation, endothelial peroxidation, and albumin leakage of rat mesenteric venules were observed. Serum myeloperoxidase(MPO) level, intercellular adhesion molecule-1(ICAM-1) expression and Src phosphorylation were examined.Results: PNS ameliorated leukocyte adhesion and mast cell degranulation, while with no obvious effects on endothelial peroxidation and albumin leakage. In addition, PNS inhibited serum MPO increase, intestinal ICAM-1 expression and Src phosphorylation induced by I/R.Conclusions: PNS ameliorated I/R-induced leukocyte adhesion and mast cell degranulation, the former is related to its inhibition of Src phosphorylation and ICAM-1 expression.展开更多
