摘 要:目的研究促性腺激素释放激素(GnRH)类似物抑制卵巢癌裸鼠皮下移植瘤生长,同时保护化疗裸鼠卵巢功能的双重作用。方法构建卵巢癌Es一2细胞裸鼠皮下移植瘤模型,随机分为6组(每组6只):(1)生理盐水(NS)组:皮下注射NS0.1ml/d,1周后腹腔注射NS0.2mL/周;(2)顺铂(DDP)组:皮下注射NS0.1ml/d,1周后每周腹腔注射5me,/kgDDP;(3)戈舍瑞林(goserelin)组:皮下注射goserelin100斗∥d,l周后腹腔注射NS0.2ml/周;(4)goserelin+DDP组:皮下注射goserelin100μg/d,1周后每周腹腔注射5mg/kgDDP;(5)西曲瑞克(cetrorelix)组:皮下注射cetrorelix100¨g/d,1周后腹腔注射NS0.2ml/周;(6)cetrorelix+DDP组:皮下注射cetrorelix100斗g/d,1周后每周腹腔注射5mg/kgDDP。用药21d,观察29d。比较各组裸鼠体质量、移植瘤体积、移植瘤组织中细胞增殖相关核抗原Ki-67的阳性率、动情周期、卵巢各级卵泡比例、血清抗苗勒管激素(AMH)、卵泡刺激素(FSH)、雌二醇、孕酮水平的差异。结果各组裸鼠体质量无明显差异(P〉0.05),用药第29天NS组为(19.8±2.2)g,DDP组(20.5±1.4)g,gosereline组(19.6-4-0.9)g,goserelin+DDP组(19.7±1.6)g,cetrorelix组(20.7±2.2)g,cetrorelix+DDP组(19.0S-1.7)g,分别比较,差异均无统计学意义(P〉0.05)。用药第12天裸鼠移植瘤体积:NS组为(2414-179)ITIm。,DDP组(78±20)mm^3,gosereline组(78±55)mnl^3,goserelin+DDP组(64±48)mm^3,cetrorelix组(78±64)mm’,cetrorelix+DDP组(70±19)mill’,用药组均明显小于NS组,差异有统计学意义(P〈0.05);第15、19、22、26、29天各用药组移植瘤体积也均明显小于NS组(P〈0.05)。NS组Ki一67阳性率为(33-4-10)%,DDP组为3.5%,goserelin组8.8%,goserelin+DDP组1.5%,cetrorelix组�Objective To investigate the influence of gonadotropin-releasing hormone (GnRH) analogues on ovarian cancer and ovarian function in vivo. Methods ES-2 cells were cultured and xenotransplanted into 36 nude mice, which were divided into 6 groups:normal saline (NS) group:NS 0. 1 ml/day subcutaneous injection, and then NS 0. 2 ml/week peritoneal injection; cisplatin (DDP) group: NS 0.1 ml/day subcutaneous injection, and then DDP 5 mg/kg (diluted to 0.2 ml ) per week peritoneal injection; goserelin group: 100 txg goserelin (diluted to 0. 1 ml) per day subcutaneous injection, and then NS 0. 2 ml/week peritoneal injection; goserelin + DDP group:100 txg goserelin (diluted to 0. 1 ml) per day subcutaneous injection, and DDP 5 mg/kg ( diluted to 0. 2 ml) per week peritoneal injection; cetrorelix group : 100 μg cetrorelix ( diluted to 0. 1 ml) per day subcutaneous injection and NS 0. 2 ml/week peritoneal injection ; cetrorelix + DDP group : 100 μg cetrorelix ( diluted to O. 1 ml) per day subcutaneous injection and DDP 5 mg/kg ( diluted to 0. 2 ml) per week peritoneal injection. All the peritoneal injection started from subcutaneous injection one week later. To compare the weight of nude mice, the volumes of transplanted tumors, the expression of Ki-67 antigen in transplanted tumors, the estrus, the ratio of atretic follicles, the ratio of primary and preantral follicles, the levels of serum anti-Mullerian hormone (AMH), follicle- stimulating hormone (FSH), estradio (E2 ) and progesterone (P) in each group. Results There were no significant difference in the weight of nude mice among 6 groups (P 〉 0. 05), which on day 29 in NS group was ( 19. 8 ±2. 2) g, DDP group (20. 5 ± 1.4) g, gosereline group ( 19. ±60. 9) g, goserelin + DDP group ( 19. 7± 1.6) g, cetrorelix group (20. 7 + 2. 2) g, and cetrorelix + DDP group ( 19. 0± 1.7) g. The tumor volumes of different groups on the 12th day: NS group (241 + 179�
