胰岛素泵治疗对不同病程2型糖尿病患者8-异前列腺素F2α的影响

8-异前列腺素F2α是细胞膜上脂化的花生四烯酸受自由基攻击后裂解而形成的前列腺素衍生物,其产生与机体氧化应激损伤关系极为密切,是评价氧化应激和脂质过氧化反应最有效的生物指标之一[1].其可以促进胰岛素抵抗及胰岛β细胞功能凋亡.2型糖尿病被证实与氧化应激及炎症密切相关,C-反应蛋白是反应炎症的重要因子.胰岛素泵强化治疗可在短期内获得理想的血糖控制,逆转高血糖的某些毒性作用,使胰岛β细胞功能得到恢复,胰岛素分泌增加,改善机体胰岛素抵抗[2].目前国内外对胰岛素泵干预对8-异前列腺素F2α及C反应蛋白的影响尚未见相关报道,本试验通过对不同病程的2型糖尿病患者胰岛素泵强化治疗,测定8-异前列腺素F2α及C反应蛋白的变化情况,探讨胰岛素泵在氧化应激及炎症中的作用.     

阿托伐他汀在急性冠状动脉综合征早期干预对8-异前列腺素F2α的影响

目的研究阿托伐他汀对急性冠状动脉综合征（ACS）患者早期干预对血浆8-异前列腺素F2α（8-iso-PGE2α）水平的影响，从而了解其对氧化应激损伤的作用。方法采用随机、双盲、对照方法将60例ACS患者分为2组。A组为阿托伐他汀治疗组（30例），B组为常规治疗组（30例）。分别在治疗前后测定血浆8-so-PGF2α和总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白胆固醇（HDL-C）、低密度脂蛋白胆固醇（LDL-C）水平。结果治疗前血浆8-iso-PGF2α B组明显高于A组（P〈0．01），且随病情加重8-iso-PGF2α升高越明显（P〈0．01）；治疗1周后，A组8-iso-PGF2α较治疗前下降42．23％。而B组仅下降4．44％。血脂水平A组较治疗前有轻度下降，TC下降3．54％，TG下降4．83％，LDL-C下降3．74％，HDL-C升高1．80％；而B组治疗前后血脂水平相比差异无显著性。A组治疗前后血浆8-iso-PGF2α下降与血脂各指标下降的幅度不平行。结论阿托伐他汀在ACS早期发挥了抗氧化应激作用，且独立于其调脂作用之外。建议只要无禁忌证，在ACS早期尽可能早地应用他汀粪药物．

Methods Radioimmunoas-say was applied to measuring plasma levels of ET, TXB2and 6-keto-PGF1αat 0,30 min, 1 day and 3 days after PTCA in 41 patients with coronary heart disease. Results The level of ET in the patients with coronary heart disease was significantly decreased in 30 minutes after PTCA (P＜0.05), but no significant difference was observed in 1 day and 3 days after PTCA (P>0.05). The level of plasma TXB2has no statistical difference after PTCA in 30minutes, 1 day and 3 days (P>0.05). The level of 6-keto-prostaglandin F1α(6-keto-PGF1α) of the patients with coronary heart disease was significantly declined in 30 minutes after PTCA (P<0.05) ,but no significant difference was observed in 1 day and 3 days after PTCA (P>0.05). Conclusion PTCA may lead to fluctuation of plasma levels of ET, TXB2and 6-keto-PGF1αThe clarification of changing regularity of these vasoactive substances contrib-utes to prevention of acute artery occlusion or restenosis after PTCA.
