子痫前期患者血清内脏脂肪素水平的变化及意义

目的 探讨子痫前期(PE)患者血清内脏脂肪素(VF)水平的变化及意义.方法 选取PE患者81例,其中轻度PE 39例(轻度PE组),重度PE 42例(重度PE组),另选择45例健康孕妇作为对照组.检测各组孕妇空腹血糖(FPG)、空腹胰岛素(FINS)、总胆固醇(TC)及三酰甘油(TG)水平,采用稳态模型评估胰岛素抵抗指数(HOMA-IR).采用ELISA法检测血清VF水平.结果 三组FPG、FINS、HOMA-IR比较差异无统计学意义(P>0.05);重度PE组TG、TC高于对照组和轻度PE组(P<0.05).重度PE组血清VF水平为(22.45±4.18)μg/L,显著高于对照组(14.52±3.25)μg/L]和轻度PE组(18.75±3.96)μg/L](P<0.05).PE患者血清VF水平与FPG、FINS水平无相关性(r=0.21、0.24,P>0.05);PE患者血清VF水平与HOMA-IR、TC及TG呈正相关(r=0.42、0.36、0.41,P<0.05).结论 PE患者血清VF水平增加,VF水平与PE的严重程度、胰岛素抵抗和脂质代谢有关.

The changes and significance of serum visfatin levels in patients with preeclampsia

Objective To explore the changes and significance of serum visfatin (VF) levels in patients with preeclampsia (PE). Methods Eighty-one cases of PE were served as observed group, 39 cases of mild PE (mild PE group) and 42 cases of severe PE(severe PE group), 45 cases of normal pregnant women as control group. Fasting plasma glucose (FPG), fasting insulin (FINS), total cholesterol (TC) and triglyceride (TG) were measured and the homeostasis model assessment insulin resistance (HOMA-IR) were evaluated in these cases. The levels of serum VF were determined by enzyme-linked immunosorbent assay. Results There were no significant difference in the levels of FPG, FINS, HOMA-IR among three groups (P > 0.05). The levels of TG, TC were significantly increased in severe PE group compared with mild PE group or control group (P < 0.05). The level of serum VF in severe PE group (22.45 ± 4.18) μ g/L]was significantly higher than that in control group (14.52 ± 3.25) μg/L]and mild PE group (18.75 ± 3.96) μ g/L](P < 0.05). The level of serum VF had no relationship with the levels of FPG, FINS (r = 0.21,0.24, P > 0.05), the positively correlation was found between the level of serum VF and HOMA-IR, TC, TG (r = 0.42,0.36,0.41, P < 0.05) in patients with PE. Conclusion VF elevates in the patients with preeclampsia and closely relates with the severity of PE, insulin resistance and lipid metabolism.
