【Abstract】 AIM: To investigate the relations between preeclamptic pathogenesis and changes of serum leptin and soluble leptin receptor in preeclampsia, and their clinical significance. METHODS: The peripheral venous blood samples of 40 preeclampsia and 43 normal pregnant women were obtained before and 7 d after operation. The level of leptin was valued by immunoradioassay, and the level of soluble leptin receptor was measured by enzymelinked immunosorbent assay(ELISA). The correlative analysis between the levels of serum leptin and soluble leptin receptor and the blood pressure was performed. RESULTS: The level of leptin before operation was higher than that after operation in all the pregnant women; The level of leptin before operation in preeclampsia was higher than that in normal pregnancy, and the level of soluble leptin receptor before operation in preeclampsia was lower than that in normal pregnancy ; The leptin before operation in preeclampsia was negatively correlated with the soluble leptin receptor, and there were positive correlations between the leptin before operation in preeclampsia and the diastolic pressure or systolic pressure; There were negative correlations between the soluble leptin receptor before operation in preeclampsia and the diastolic pressure or systolic pressure. CONCLUSION: The high level of leptin in preeclampsia may come from placenta, and it may be related to the preeclamptic pathophysiology. The level of leptin or soluble leptin receptor can be a clinical marker to reflect the degree of preeclampsia.

【摘要】 目的： 探讨子痫前期血清瘦素及可溶性瘦素受体水平与子痫前期发病之间的关系及其临床意义. 方法： 40例子痫前期孕妇及43例正常妊娠孕妇，取术前及术后7 d外周静脉血，应用放射免疫法检测瘦素水平，应用ELISA法检测可溶性瘦素受体水平，并与子痫前期的血压值进行相关分析. 结果： 子痫前期组和正常妊娠组术后瘦素水平均低于术前；子痫前期组术前瘦素水平高于正常妊娠组，可溶性瘦素受体水平低于正常妊娠组；子痫前期组术前瘦素水平与可溶性瘦素受体水平呈负相关，与收缩压和舒张压呈正相关；子痫前期组术前可溶性瘦素受体水平与收缩压和舒张压均呈负相关. 结论： 子痫前期升高的瘦素可能来源于胎盘，并可能参与子痫前期的病理生理过程. 血清中瘦素及可溶性瘦素受体水平可作为反映疾病程度的临床指标.

0引言
瘦素是肥胖（obese）基因的蛋白产物，主要是由脂肪细胞合成和分泌，参与机体的能量代谢. 但近年来研究发现，瘦素与妊娠和生殖调节也存在密切关系［1-2］. 我们观察了子痫前期患者血清瘦素及可溶性瘦素水平变化，以探讨血清瘦素及可溶性瘦素受体与子痫前期之间的关系及其临床意义.
