高血压病患者血清单核细胞趋化因子-1的变化及其与血管紧张素Ⅱ的关系

目的　检测高血压病患者外周血中单核细胞趋化因子 - 1(MCP - 1)和血管紧张素Ⅱ (AngⅡ )的变化 ,并分析两者的相关关系。方法　分别用ELISA和放射免疫法测定 32名高血压病患者和 30名正常人外周血MCP - 1和AngⅡ的浓度。 结果　同正常人组相比 ,高血压病患者外周血MCP - 1浓度明显增高 (P<0 .0 0 1) ,但两组AngⅡ浓度差异无显著性 (P =0 .887) ,血MCP - 1浓度同血压、AngⅡ浓度无相关性。 结论　高血压病患者外周血炎症因子MCP - 1浓度增加 ,但与血压升高的程度以及外周血AngⅡ浓度无关。

脂氧素A4对心肌缺血再灌注损伤的保护作用

Objective To investigate the roles of lipoxin A4, an endegenous lipid mediator with wide anti-inflammatory fea- tures, in attenuating myocardial ischemia-reperfusion injury and the possible mechanisms. Methods Thirty male KM mice were divid- ed randomly into three groups, 10 in each: ischemia-reperfusion group (group A), lipoxin A4 (0.1 mg/kg) group (group B) and Zn- PP (Zinc protoporphyrin Ⅸ, 25 mg/kg)phus lipoxin A4 (0.1 mg/kg)group (group C). A ischemia-reperfusion heart model was de- veloped by ligating the lift anterior descending branch of the coronary artery. A dine of 10% dehydrated alcohol in 0.2 ml for group A, a dose of isochoric lipoxin A4 for group B and a dose of isochoric ZnPP + lipoxin A4 for group C was infused into the ascending aorta through a catheter, which was kpassing the right common carotid artery, 30 minutes after reperfusion. The concentration of serum TNF-α, activities of serum crestine kinase(CK) and lactate dehydrogenase (LDH), activities of myeloperoxidase (MPO) and malond- ialdehyde (MDA) and the cell apoptosis rate in the myocardial tissue were measured 5 hours after reperfusion. Pathological features of the inflammatory infiltration in the myocardium were also observated.Results As compared with group A, the inflammatoryry infiltra- tion in the ischemic and necrotic regions tithe myocardium was reduced, with group C in the intermediate range. The serum activities of CK and LDH wine significantly lower in group B and C than that in group A, and the lowest activities were detected in group B. Similar findings were observed for MPO, an indicator for neutrophil infiltration, and MDA, an indictor for cell injury caused by oxy- gen radicals, in the myocardium. The concentration of TNF-α and the rate of cadiocyte apoptosis were decreased significantly in group B(P < 0.01). ZnPP, an inhibitor of heine oxygenase (HO)-1, attenusted the above protective effects of lipoxin A4 significantly (P<0.05). Conclusion Lipoxin A4 has protective effects against myocardial ischemia-reperfusion injury, and HO-1 may have a potential role in the protectve mechanisms of lipoxin A4, probably pertly by means of reducing the production of reactive oxygen spe- cies and TNF-α, decreasing the activation and infiltration of neutrophils, alleviating inflammatory damage and avoiding apoptosis.
