Methods Blood samples of fifty-two patients who underwe n t open heart surgery with CPB were collected from right internal jugular vein at p oints as pre-CPB, rewarming, aortic declamping, 6 hours and 24 hours after CPB. Cytokines, iNOS, S-100 and NSE were assayed accurately. In addition, its corre lation between them were also analysed.

方法于 CPB前、复温即刻、主动脉开放和 CPB后 6、2 4小时采集 5 2例心脏病患者颈内静脉血，检测 S- 10 0蛋白和 NSE的浓度，并将其与炎性细胞因子白细胞介素- 6 (IL- 6 )、白细胞介素- 8(IL- 8)、肿瘤坏死因子-α和诱导型一氧化氮合成酶的浓度变化进行相关性分析。

Methods: Twenty-four male SD rats were randomly divided into normal control (NC, n=6), protein C activator (PCA, n=6), lipopolysaccharide (LPS, n=6) and LPS+PCA group (n=6). NC group were given normal saline and PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. LPS group were administered lipopolysaccharide (10 mg/kg, 4h) by intraperitoneal injection method to make the model of septic shock rats. After the animal model was made, LPS+PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. 30 minutes after the injection, each rat was tested by Medlab biosignal analyzing system for observing mean arterial pressure and left ventricle function, the activity of LDH and iNOS in myocardium and the cuttings of myocardial tissues.

取SD雄性大鼠24只随机分成对照组、PCA组、LPS组和LPS+PCA组四组，对照组尾静脉注射生理盐水，PCA组尾静脉注射蝮蛇毒蛋白C激活物，LPS组腹腔注射LPS (10 mg/kg， 4h)的方法建立败血症休克的实验动物模型，在建立败血症的实验动物模型的基础上，尾静脉注射PCA (0.4 mg/kg)为LPS+PCA组，每只大鼠均于药后30 min时运用Medlab生物信号采集处理系统记录平均动脉压和左心室功能指标，并测定心肌中乳酸脱氢酶活性、诱导性一氧化氮合酶活性及心肌病理切片。
