摘要目的 探讨人工授精妊娠期孕酮(P)、γ-干扰素(IFN-γ)水平与妊娠结局的相关性.方法 选择因不孕症行468个人工授精治疗周期患者,术后口服地屈孕酮予以黄体支持,对妊娠的54例患者观察P、IFN-γ水平.结果 正常妊娠组P与IFN-γ水平呈负相关(r=-0.576,P＜0.05).生化妊娠组第9天开始P水平下降,与正常妊娠组比较,差异有统计学意义(t=12.319,P＜0.05).流产组P水平从第16天开始下降,与正常妊娠组差异有统计学意义(t=7.663、19.315,均P＜0.05).与正常妊娠组比较,流产组及生化妊娠组的IFN-γ水平均显著升高(P＜0.05).结论 使用黄体支持方法提高体内P水平对预防生化妊娠和自然流产有着积极的作用,人工授精后监测P、IFN-γ的水平,可以预测患者的预后.

abstractsObjective To investigate the correlation of P,IFN-γlevel of artificial insemination during pregnancy and pregnancy outcome.Methods 468 patients with infertility were done artificial insemination treatment cycles.The dydrogesterone were taken orally after surgery to luteal support.The blood P and IFN-γlevel of 54 patients with pregnant were observed.Results The correlation analysis of P,IFN-γ level of normal pregnancy group showed that the P level was negatively correlated with IFN-γlevel (r =-0.594,P ＜ 0.05).In the biochemical pregnancy group,the P level was decreased from the ninth days begin,and compared with the normal pregnancy group,the difference was significant(t =12.319,P ＜0.05).In the abortion group,the P level was decreased from the sixteenth days begin,and compared with the normal pregnancy group,the difference was significant (t =7.663,19.315,all P ＜0.05).Compared with the normal pregnancy group,the IFN-γ level of the biochemical pregnancy group and abortion group was significantly increased,the difference was significant (P ＜ 0.05).Conclusion The use of luteal support methods to raise the level of P in vivo has a positive effect on the prevention of biochemical pregnancy and spontaneous abortion,and monitoring the blood P and IFN-γlevel after artificial insemination can predict the prognosis of patients.
