为了探讨特技飞行能否使血脂及载脂蛋白发生变化从而导致冠心病早发以及能否损伤心肌细胞，我们使用Ｂｅｃｋｍａｎ系列分析仪及试剂对２０例健康男性飞行员进行复杂特技飞行前（６Ａ．Ｍ，空腹）、飞行后即刻（１０Ａ．Ｍ）、６Ｈ（４Ｐ．Ｍ）及２４ｈ（次日１０Ａ．Ｍ）血清胆固醇（ＴＣ）、甘油三脂（ＴＧ）、载脂蛋白ＡＩ（ａｐｏＡＩ）、Ｂ（ａｐｏＢ）及ＧｏＴ、ＣＰＫ、ＬＤＨ、α－ＨＢＤ检测。结果：（ｌ）飞行后即刻血糖、ＴＧ及ａｐｏＡＩ明显升高，与飞行前及飞行后６ｈ、２４ｈ比较有显著性差异（Ｐ＜０．０５），飞行后６ｈ、２４ｈ与飞行前比较，血糖、ＴＧ及ａｐｏＡ１均无显著性差异（Ｐ＞０．０５）。（２）飞行后即刻ａｐｏＡ１／ａｐｏＢ比值下降，但与飞行前及飞行后６ｈ、２４ｈ比较均无显著性差异（Ｐ＞０．０５）。（３）血清ＧＯＴ、ＣＰＫ、ＬＤＨ、α─ＨＢＤ一天内不同时间水平不一，但均在正常范围，飞行前后无有意义的变化。飞行后血清ＴＧ升高是由于特技飞行后血糖及游离脂肪酸增加所致，血中含ＴＧ丰富的ＶＬＤＬ可能有轻微的致动脉粥样硬化作用，而含ａｐｏＡＩ丰富的ＨＤＬ与冠心病的发生呈负相关。根据以上结果，我们认为复杂特技飞行不会引起冠心病早发也不会引起?
In order to investigate whether aerobatics can change blood lipids and apolipoproteins leading to early onset of coronary heart disease and whether they can damage cardiomyocytes, we used Beckman series of analyzers and reagents to test 20 healthy male pilots before complex aerobatics (Fasting), serum cholesterol (TC), triglyceride (TG), apolipoprotein AI (apoAI), B (ApoB) and GoT, CPK, LDH, α-HBD detection. Results: (1) Immediately after the blood glucose, TG and apoAI were significantly increased, compared with those before and 6h and 24h after the flight (P <0.05). After 6h and 24h after the flight, blood glucose , TG and apoA1 no significant difference (P> 0.05). (2) The ratio of apoA1 / apoB decreased immediately after the flight, but there was no significant difference between pre-flight and post-flight 6h and 24h (P> 0.05). (3) Serum GOT, CPK, LDH, α-HBD differed at different times of the day, but all were within the normal range, with no significant changes before and after flight. Elevated serum TG after flight is due to an increase in blood glucose and free fatty acids after aerobatics. TG-rich VLDL in the blood may have a slight atherogenic effect, whereas apoAI-rich HDL and coronary heart disease are negative Related. Based on the above results, we believe that complex aerobatics will not cause coronary heart disease will not cause early?
