摘要
目的:通过研究基质金属蛋白酶(MMP-2、MMP-9)及其组织抑制剂(TIMP-1、TIMP-2)在不同类型滋养细胞疾病中的表达,探讨基质金属蛋白酶系统与滋养细胞疾病临床病理参数的相关性,寻求可以预测滋养细胞疾病恶变和滋养细胞肿瘤转移潜能的指标,为临床早期预测滋养细胞疾病的恶变及预防性化疗提供可靠依据。
     方法:应用链霉菌抗生物素蛋白—过氧化物酶免疫组织化学方法对20例正常早孕((12周)绒毛组织、15例部分性葡萄胎、55例完全性葡萄胎、15例侵蚀性葡萄胎、8例绒毛膜癌组织中MMP-2、MMP-9、TIMP-1、TIMP-2进行检测。
     结果:
     (1) MMP-2在不同类型滋养细胞中的表达无显著性差异(X~2=0.926,P=0.921);
     (2) MMP-9在正常早孕绒毛组织、部分性葡萄胎、完全性葡萄胎、侵蚀性葡萄胎、绒毛膜癌中均100%表达,但随着滋养细胞恶性程度的增加其表达显著升高,差异具极显著性(X~2=26.421,P=0.0001);
     (3) TIMP-1在正常早孕绒毛组织均有表达,而在部分性葡萄胎、完全性葡萄胎、侵蚀性葡萄胎、绒毛膜癌中分别有表达6.67%、5.45%、6.67%、12.50%不表达,且随着肿瘤恶性程度的升高,其染色程度和染色细胞百分率减少,差异具极显著性(X~Z=9.575,P=0.048):
     (4) TIMP-2在各组织中的表达无显著性差异(X~2=1.462,P=0.833)。
     (5) 葡萄胎患者MMP-9的表达与年龄和刮宫次数有相关性,(分别为

    rs==0·262,P=0,028;rs=0.390,P=0.001)。TIMP一l的表达在卵巢黄素化囊肿
    有无、刮宫前血B一HCG值、血B一HCG转阴时间、妊娠呕吐、有无合并妊娠
    高血压综合征等病理参数中显示有差别,与刮宫次数有相关性;
     (6) MMP一9在发生恶变的葡萄胎组织中和未发生恶变的葡萄胎组织中
    的表达无显著性差异(Mann一WhitneyU=1 1 6.0,p=0.320)。而TIMp一1在发生
    恶变的葡萄胎组中的表达明显低于未发生恶变组,(Mann一whitneyu=77.00,
    P=0 .015)。
     (7)在侵蚀性葡萄胎中MMP一9、TIMP一1的表达与病理分型无相关性
     (rs=0.196,p=0.485;rs=一0.495,p=0.061),但在发生转移和未发生转移的
    病例比较中MMp一9、TIMp一l表达均有显著性差异(Mann一WhitenyU=4,
    P=0 .021;Mann一WhitenyU=5.5,p=0.01)。
     (8) MMP一9在绒癌中的表达多为(++)一(+++)级,尤其是在有转移
    瘤的病例及转移瘤个数多的病例表达增强,而TIMP一1表达多集中在(+)级。
     结论:MMP一2、MMP一9参与了正常早孕滋养细胞的侵袭的过程,而
    TIMP-1、TIMP一2使滋养层细胞以一种可控制的形式侵袭。MMP一9和TIMP一1
    可能参与了滋养细胞疾病的浸润和血管生成,随着滋养细胞肿瘤恶性程度的
    增加MMP一9表达上调而TIMP一1表达下调。MMP一9/TIMP一1比值的改变可引
    起滋养细胞疾病的恶变和转移,MMP一9/TIMP一1可望成为临床早期预测滋养
    细胞疾病的恶变及预防性化疗的指标。MMPs厅IMPs比例的改变也可能是滋
    养细胞疾病发生妊娠高血压综合征的原因之一。MMP一2、TIMP一2可能与滋
    养细胞浸润无密切关系。HCG可能影响葡萄胎TIMP一1的表达,MMP一9与葡
    萄胎患者的年龄和刮宫次数有关。
Objective: To study the expression of matrix metallopreteinases (MMP-2,9) and tissue inhibitors of metallopreteinases (TIMP-1,2) in human gestational trophoblastic disease and their correlation with clinic pathological parameters in predicting the malignant transformation and metastasis.
    Methods: Immunohistochemical streptavidin-peroxidase (S-P) method was used to detect the expression of MMP-2, MMP-9, TIMP-1, TIMP-2 in 20 cases of normal human cytotrophoblast cells, 15 cases of partial hydatidiform moles, 55 cases of complete hydatidiform moles, 15 cases of invasive moles and 8 cases of choriocarcinoma.
    Results:
    (1) No significant difference with MMP-2 expression in all cases. (X2=0.926, P=0.921)
    (2) MMP-9 expression was detected in all types of trophoblastic cells, with the development of the malignant transformation the staining was markedly increased.
    (X2=26.421, P=0.0001)
    (3) Each cases of normal human cytotrophoblast cells expression TIMP-1, but 6.67% of partial hydatidiform moles, 5.45% of complete hydatidiform moles, 6.67% of invasive moles and 12.50% of choriocarcinoma were negative. With the
    
    
    development of the malignant transformation the staining was decreased. (X2=9.575, P=0.048)
    (4) The expression of TIMP-2 in all cases has no significant difference. (X2=1.462, P=0.833)
    (5) In hydatidiform moles, the expression of MMP-9 correlated with age and times of curettage (rs=0.262 , P=0.028; rs=0.390, P=0.001) . The expression of TIMP-1 was decreased in women with the hydatidiform moles complicated theca lutein ovarian cyst, hyperemesis gravidarum, pregnancy-induced hypertension syndrome, higher -HCG serum values,and the longer time for negative-transition of HCG. TIMP-1 also assosciate with times of curettage in the hydatidiform moles.
    (6) No significant difference of MMP-9 expression in hydatidiform mole between malignant transformation and without malignant transformation. (Mann-Whitney U=116.0 , P=0.320) But much lower TIMP-1 expression in malignant transformation cases. (Mann-Whitney U=77.00, P=0.015)
    (7) In invasive moles no correlation was found among the MMP-9, TIMP-1 and the pathological types. (rs=0.196, P=0.485; rs=-0.495, P=0.061) But the expression of MMP-9 and TIMP-1 was significant difference between the malignant cases and without malignant cases. (Mann-WhitenyU=4> P=0.021 ; Mann-WhitenyU=5.5, P=0.01)
    (8) The expression of MMP-9 in choriocarcinoma was increased especially in matastasis cases,while the TIMP-1 was decreased in the same cases.
    Conclusion: MMP-2 and MMP-9 be involved in the invasion of the normal human cytotrophoblast cells, while TIMP-1 and TIMP-2 make this invasion controllable. MMP-9 and TIMP-1 probably be involved in invasion of the human gestational trophoblastic disease and angiogenesis. Upregulation of the MMP-9 and downregulation of the TIMP-1 with the malignancy degree in the
    
    
    trophoblastic disease . The invasion and metastasis may caused by the change of MMP-9/TIMP-1 .The ratio of MMP-9/ TIMP-1 can be used as indicators to reference the stage of gestational trophoblastic disease development, provide the evidence to assess the prognosis and clinical thearpy. The change of MMPs/TIMPs might be one reason of pregnancy-induced hypertension syndrome in the human gestational trophoblastic disease. MMP-2 and TIMP-2 might have no closely related to the invision of trophoblast. Human thorionic gonadotropin may play an important role in the expression of TIMP-1. The expression of MMP-9 correlated with age and times of curettage in hydatidiform moles.
