摘要:

背景:有研究表明,卵泡发育、成熟、排卵和黄体形成以及退化等卵巢的生理过程都涉及细胞外基质的形成,而基质金属蛋白酶9和结缔组织生长因子与细胞外基质的形成有着密切的关系。
目的:探讨卵巢中结缔组织生长因子及基质金属蛋白酶9的表达与多囊卵巢综合征的关系。
方法:将有规律动情周期的SD雌性大鼠随机分为2组,模型组大鼠采用来曲唑灌胃建立多囊卵巢综合征模型,对照组灌胃等量的羧甲基纤维素。当模型组大鼠动情周期固有规律不存在,连续出现间期时采集大鼠的血清和卵巢组织,对照组在其间期采集标本进行检测。
结果与结论:放射免疫分析法和免疫组织化学染色法检测显示,与对照组相比,模型组的血清促黄体生成激素、血清垂体泌乳素、窦前卵泡卵泡膜胞浆中的结缔组织生长因子、卵泡基底膜胞浆结缔组织生长因子、白膜结缔组织生长因子以及黄体中基质金属蛋白酶9表达量明显升高(P < 0.05),促卵泡激素、血清雌二醇和卵泡基底膜中的基质金属蛋白酶9表达量则明显降低(P < 0.05)。结果证实,结缔组织生长因子可能与多囊卵巢综合征中可能与小卵泡的过多生长和排卵障碍有关,基质金属蛋白酶9可能与多囊卵巢综合征中的排卵障碍有关。

Abstract:

BACKGROUND: Several studies have demonstrated that the physiological process of the ovary, including follicle development, maturity, ovulation, corpus luteum formation and regression, is related to the formation of extracellular matrix. However, matrix metalloproteinase 9 and connective tissue growth factors had a close relationship with the formation of extracellular matrix.
OBJECTIVE: To investigate the relationship between the expression of connective tissue growth factor and matrix metalloproteinase 9 and polycystic ovary syndrome.
METHODS: The female SD rats with regular estrous cycle were randomly divided into control and model groups. The rats in the model group were intragastrically with letrozole to establish the model of polycystic ovary syndrome, while the rats in the control group were intragastrically with the same amount of carboxymethyl cellulose. When the natural law of estrous cycle of rats in the model group did not exist and consecutive interval appeared, rat serum and ovarian tissues were collected. Rats in the control group were detected by collecting specimen in the interval.
RESULTS AND CONCLUSION: Radioimmunoassay and immunohistochemical staining results showed that compared with the control group, the expression of serum luteinizing hormone, serum prolactin levels, connective tissue growth factor in preantral follicles theca cytoplasm, connective tissue growth factors in follicular basement membrane cytoplasm, connective tissue growth factors in albuginea and matrix metalloproteinase 9 in corpus luteum significantly increased (P < 0.05). The contents of follicle stimulating hormone and serum estradiol, and expression of matrix metalloproteinase 9 in follicular basement membrane significantly decreased (P < 0.05). The 
results indicate that connective tissue growth factors may be related to the excessive growth of small follicles and ovulation disorders in polycystic ovary syndrome, while matrix metalloproteinase 9 may be related to ovulation disorders in polycystic ovary syndrome.
