目的 探讨米非司酮对胚胎生长及蜕膜肿瘤坏死因子-α(TNF-α)和转化生长因子-β(TGF-β)表达的影响。方法 30例不同孕龄的早孕药物流产妇女(药流组),予口服米非司酮25 mg ,每日2次共3 d,72 h 后加服米索前列醇600 μg。另选取30例正常育龄人工流产妇女(人流组)做对照。采用免疫组化测定两组妇女蜕膜组织中TNF-α和TGF-β的表达程度及量化均值水平。结果 (1)人流组蜕膜组织中TNF-α和TGF-β阳性表达率分别为70.00%(21/30)和86.67%(26/30);药流组蜕膜组织中TNF-α和TGF-β阳性表达率分别为73.33%(22/30)和86.67%(26/30);两组间比较,差异无显著性(P>0.05)。(2)药流组蜕膜中TNF-α表达程度(+ +~+ + +为9例)显著高于人流组(+ +~+ + +为4例),两组间比较,差异有显著性(P<0.05);药流组蜕膜中TGF-β量化均值为0.666 7,显著低于人流组量化均值0.916 7的水平(P<0.05)。结论 口服米非司酮药物流产妇女的蜕膜组织中,出现的TNF-α升高及TGF-β的降低,可能是蜕膜组织因子网络平衡状态紊乱的表现,米非司酮可能通过抑制TGF-β的活性,刺激 TNF-α的分泌作用对胚胎发育产生不良影响。
目的 探討米非司酮對胚胎生長及蛻膜腫瘤壞死因子-α(TNF-α)和轉化生長因子-β(TGF-β)錶達的影響。方法 30例不同孕齡的早孕藥物流產婦女(藥流組),予口服米非司酮25 mg ,每日2次共3 d,72 h 後加服米索前列醇600 μg。另選取30例正常育齡人工流產婦女(人流組)做對照。採用免疫組化測定兩組婦女蛻膜組織中TNF-α和TGF-β的錶達程度及量化均值水平。結果 (1)人流組蛻膜組織中TNF-α和TGF-β暘性錶達率分彆為70.00%(21/30)和86.67%(26/30);藥流組蛻膜組織中TNF-α和TGF-β暘性錶達率分彆為73.33%(22/30)和86.67%(26/30);兩組間比較,差異無顯著性(P>0.05)。(2)藥流組蛻膜中TNF-α錶達程度(+ +~+ + +為9例)顯著高于人流組(+ +~+ + +為4例),兩組間比較,差異有顯著性(P<0.05);藥流組蛻膜中TGF-β量化均值為0.666 7,顯著低于人流組量化均值0.916 7的水平(P<0.05)。結論 口服米非司酮藥物流產婦女的蛻膜組織中,齣現的TNF-α升高及TGF-β的降低,可能是蛻膜組織因子網絡平衡狀態紊亂的錶現,米非司酮可能通過抑製TGF-β的活性,刺激 TNF-α的分泌作用對胚胎髮育產生不良影響。

Objective To investigate the effect of mifepristone on the expression of tumor necrosis factor-α(TNF-α) and transforming growth factor-β(TGF-β)in decidua of early pregnancy. Methods Thirty artificial abortion women as control and thirty drug abortion women were enrolled for study. The expressions of TNF-α and TGF-β in decidua were measured with immunohistochemical method. Results There was no significant difference of TNF-α positive expression rates between drug abortion group (73.33%) and artificial abortion group (70.00%,P>0.05). TGF-β expression rate of drug abortion group was similar to that of artificial abortion group. The highly-positive (+ + and + + +) TNF-α expression rate in drug abortion group was significantly higher than that in artificial abortion group (P<0.05). TGF-β expression degree in decidua of drug abortion group was significantly lower than that of artificial abortion group (P<0.05). The ratio of TNF-α/TGF-β in drug abortion group is higher than that in artificial abortion group. Conclusion TGF-β has great effect on regulating the embryo development of early pregnancy. The change of TNF-α may be the reason of abortion. Mifepristone may interfere with embryo growth by inhibiting the activity of TGF-β or by stimulating the secretion of TNF-α.
