At the time of aorta opening in routine cardiac surgeries with ECC,the oxygen flux was changed respectively. Two millilitres blood was taken at the time of pre-operation（T0）,30 min after aorta opening（T1）,6 h (T2),24 h (T3) and 48 h after operation (T4) to measure the levels of serum cTnI were measured through ELISA method.

常规体外循环下进行手术，升主动脉开放时改变各组复灌氧流量，分别于术前（T0）、开放升主动脉后30 min（T1）、术后6 h（T2）、24 h（T3）、48 h（T4）各时间点抽取患者锁骨下静脉血2 ml，采用ELISA酶联免疫法测定血浆cTnI含量。

An enzyme linked immunosorbent assay was developed using heat stress protein 70 purified with its cDNA and pET vector system and the titer of antibody to HSP70 in plasma was determined in 40 control parachutists without parachuting for half year and 42 parachutists after parachuting.

目的：探讨HSP70抗体滴度在评价跳伞对空降兵健康效应中的影响。方法：利用cDNA和pET载体系统纯化的HSP70，建立检测HSP70抗体滴度的酶联免疫吸附鉴定方法，并调查了40名近半年来未跳伞的对照组空降兵和42名跳伞后的跳伞组空降兵血浆中HSP70抗体滴度。
