摘要
目的探讨体重指数(BMI)、性激素及卵泡刺激素受体(FSHR)基因rs2268361和rs2349415位点的单核苷酸多态性(SNP)与多囊卵巢综合征(PCOS)发病风险的相关性。方法收集2021年3-8月山西医科大学第一医院生殖医学科门诊就诊的213例PCOS患者(PCOS组)与207名健康对照者(对照组)的外周血,随机收集PCOS组与对照组各32例卵泡液。计算PCOS组与对照组的BMI;采用免疫化学发光法检测两组外周血卵泡刺激素(FSH)、黄体生成素(LH)、雌二醇(E_(2))、睾酮(T)、孕酮(P)和泌乳素(PRL)水平;采用聚合酶链式反应(PCR)和高分辨熔解曲线(HRM)分析两组FSHR基因rs2268361和rs2349415位点多态性;采用实时定量PCR检测两组外周血及卵巢颗粒细胞FSHR mRNA表达水平。结果LH与LH/FSH呈明显正相关(r=0.88,P<0.05);PCOS组BMI、E2、LH、LH/FSH、T水平明显高于对照组(P<0.05),FSH水平明显低于对照组(P<0.001);HRM分析显示,PCOS组rs2349415位点CC、CT、TT基因型频率分别为55.9%、34.3%和9.8%,对照组分别为68.6%、23.2%和8.2%,PCOS组C、T等位基因频率分别为73.0%、27.0%,对照组分别为80.2%、19.8%,两组基因型频率及等位基因频率比较差异均有统计学意义(P<0.05);PCOS组卵巢颗粒细胞中FSHR mRNA表达水平明显高于对照组(P=0.004),其中rs2349415 TT基因型FSHR mRNA表达水平高于CC(P=0.002)和CT基因型(P=0.035)。结论高水平的BMI、LH、E2及rs2349415位点T等位基因可增加PCOS的发病风险。
Objective To investigate the association between body mass index(BMI),sex hormone and single nucleotide polymorphisms(SNPs)of follicle-stimulating hormone receptor(FSHR)gene rs2268361 and rs2349415 and its correlation with the risk of polycystic ovary syndrome(PCOS).Methods Peripheral blood was collected from 213 PCOS patients and 207 healthy controls,attending the Department of Reproductive Medicine at the First Hospital of Shanxi Medical University,and 32 follicular fluids were randomly collected from each of the PCOS and control groups from March to August 2021.Calculation of BMI of the PCOS and control groups;The levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estradiol(E_(2)),testosterone(T),progesterone(P)and prolactin(PRL)in peripheral blood of the two groups were detected by immunochemiluminescence method.Polymerase chain reaction(PCR)and high-resolution melting curve(HRM)were used to analyze the polymorphisms of rs2268361 and rs2349415 in FSHR of the two groups.Quantitative real-time PCR was used to detect the expression of FSHR gene mRNA in peripheral blood and ovarian granulosa cells.Results There was a strong positive correlation between LH and LH/FSH(r=0.88,P<0.05);The levels of BMI,E2,LH,LH/FSH and T in PCOS group were significantly higher than those in control group(P<0.05);FSH level was significantly lower than that of control group(P<0.001).HRM analysis showed the frequencies of CC,CT and TT genotypes at rs2349415 were 55.9%,34.3%and 9.8%in PCOS group and 68.6%,23.2%and 8.2%in control group,respectively.The frequencies of C and T alleles were 73.0%and 27.0%in PCOS group and 80.2%and 19.8%in control group,respectively.There were significant differences in genotype frequencies and allele frequencies between the two groups(P<0.05);The expression level of FSHR mRNA was higher in ovarian granulosa cells in PCOS group than in control group(P=0.004),the expression level of FSHR mRNA in rs2349415 TT genotype was higher than that in CC(P=0.002)and CT(P=0.035)genotype.Conclusion High le
