摘要： ［摘要］〓
〖HTH〗目的〖HTSS〗〖KG*2〗探讨缺血性脑卒中老年患者血浆血小板活化因子乙酰水解酶(plateletactivating factoracetylhydrolase，PAFAH)与胰岛素抵抗、糖脂代谢水平的关系。
〖HTH〗方法〖HTSS〗〖KG*2〗选取100例老年缺血性脑卒中患者，根据患者血糖和血胰岛素水平计算稳态模型胰岛素抵抗指数(homeostasis model assessment insulin resistance,HOMAIR）分为IR组50例和非IR组50例，另选同期体检正常老年人30例为正常对照组；检测并对比3组空腹血糖、空腹胰岛素、HOMAIR、三酰甘油(triglycerides,TG)水平，比较各组血浆中不同结合状态的PAFAH活性并进行患者LPAFAH/HPAFAH活性比值与糖脂代谢水平和临床资料特征的相关性分析。
〖HTH〗结果〖HTSS〗〖KG*2〗IR组空腹血糖、空腹胰岛素、HOMAIR及TG水平均高于非IR组和对照组（P＜005）；IR组低密度脂蛋白胆固醇（low density lipoprotein cholesterol,LDLC）和总胆固醇（total cholesterol,TC）水平分均高于对照组（P＜005）；非IR组空腹血糖、空腹胰岛素、HOMAIR、TG、TC和LDLC水平均高于对照组（P＜005）。IR组血浆中PAFAH、LPAFAH活性和LPAFAH/HPAFAH活性比值均高于非IR组和对照组（P＜005）。经Pearson相关分析，患者血浆中平均LPAFAH/HPAFAH活性比值与HOMAIR、空腹血糖、空腹胰岛素、TG、LDLC、TC、大动脉硬化均呈正相关（r=0.654、0.597、0.532、0.442、0.612、0.336、0.466，P＜005），而与HDL-C呈负相关（r=-0.571，P＜0.05）。
〖HTH〗结论〖HTSS〗〖KG*2〗缺血性脑卒中患者血浆内PAFAH、LPAFAH及LPAFAH/HPAFAH活性比值升高可能与IR、大动脉硬化、体内慢性炎症及氧化应激状态相关，是缺血性脑卒中患者的危险因素，LPAFAH/HPAFAH活性比值有可能成为伴有IR或大动脉硬化的缺血性脑卒中患者慢性炎症状态的监测指标。

Abstract: ［Abstract］ Objective〖HTSS〗〓To investigate the relationship between plasma plateletactivating factoracetylhydrolase(PAFAH ) and insulin resistance, glucose and lipid metabolism in elderly patients with ischemic stroke.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓A total of 100 elderly patients with ischemic stroke were selected. The homeostasis model assessment insulin resistance(HOMAIR) index was calculated based on the patients′ blood glucose and insulin levels. Fifty cases were included in the IR group and 50 cases were in the nonIR group. In the same period, 30 older people with normal physical examination were selected as normal control group. Fasting blood glucose, fasting insulin, HOMAIR, and triglycerides(TG) levels were compared among the three groups. The activity of PAFAH under different binding states in each group of patients was compared. The PAFAH activity of different combinations of patients in each group was compared. The activity ratio of LPAFAH/HPAFAH activity and the characteristics of glucose lipid metabolism and clinical data were compared, and the correlation analysis was conducted.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓The average fasting blood glucose, fasting insulin, HOMAIR and TG levels in IR group were significantly higher than those in nonIR group and control group(P＜005). The levels of low density lipoprotein cholesterol(LDLC）and total cholesterol(TC) in the IR group were higher than those in the control group(P＜005). The levels of fasting blood glucose, fasting insulin, LDLC, TC and TG in nonIR group were higher than those in control group(P＜005). The plasma LPAFAH, PAFAH activity and LPAFAH/HPAFAH activity ratio in IR group were higher than those in nonIR group and control group(P＜005). The Pearson correlation analysis found that plasma LPAFAH/HPAFAH activity ratio were positively correlated with HOMAIR, fasting blood glucose, fasting insulin, TG,LDLC,TC level and aortic sclerosis in all patients(r=0.654, 0.597, 0.532, 0.442, 0.612, 0.336, 0.466, P＜005). There was a negative correlation with HDLC(r=-0.571, P＜005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The increase of plasma PAFAH, LPAFAH and LPAFAH/HPAFAH ratio in patients with ischemic stroke may be associated with IR, atherosclerosis, chronic inflammation and oxidative stress in human body, which is a risk factor for ischemic stroke patients. The LPAFAH/HPAFAH activity ratio may be a monitoring indicator of chronic inflammatory state in patients with ischemic stroke with IR or arteriosclerosis.
