    ABSTRACT: To investigate characteristics of glucose metabolism of non-obese and obese women with polycystic ovary syndrome (PCOS). From May 2006 to April 2009, 1928 PCOS patients treated in Reproductive Medicine Center of Shandong Provincial Hospital Affiliated to Shandong University were enrolled in this study, which were divided into 901 cases [body mass index (BMI) ≥ 25 kg/m²] in obese group and 1027 cases in non-obese (BMI < 25 kg/m(2)) group. The prevalence of type 2 diabetes mellitus (T2DM), oral glucose tolerance test, impaired fasting glucose (IFG), impaired glucose tolerance (IGT) were compared between the two groups. (1) Blood glucose levels: at the time of fasting, 30, 60, 120 and 180 minutes, the levels of glucose were (5.3 ± 1.1), (9.0 ± 2.4), (9.3 ± 4.4), (7.5 ± 2.8), (5.3 ± 1.8) mmol/L in obese group and (5.0 ± 0.8), (8.4 ± 3.5), (8.0 ± 4.2), (6.5 ± 3.2), (4.9 ± 1.6) mmol/L in non-obese group, which all showed statistical difference at every time point (P < 0.01). (2)The level of insulin: at the time of fasting, 30, 60, 120 min, the level of insulin were (13 ± 7), (81 ± 51), (102 ± 65), (83 ± 63) mU/L in obese group and (8 ± 5), (57 ± 35), (62 ± 44), (46 ± 39) mU/L in non-obese group, which all showed statistical difference at every time point (P < 0.01). However, at time point of 180 minutes, the level of insulin did not exhibit significantly difference between obese and non-obese group (P > 0.05). (3) The prevalence of abnormal glucose metabolism: the rate of IFG was 4.98% (96/1928). The rate of abnormal glucose tolerance was 23.08% (445/1928). The rate of IGT were 13.05% (134/1027) in non-obese group and 24.20% (218/901) in obese group, which also showed remarkable difference (P < 0.01). The rate of T2DM were 2.53% (26/1027) in non-obese group and 7.44% (67/901) in obese group, which reached significant difference (P < 0.01). Abnormal glucose metabolism was observed more frequently in overweight or obese PCOS women.

    ABSTRACT: To determine a suitable standard of hirsutism for Chinese polycystic ovary syndrome (PCOS) patients living in Shandong region. A total of 623 unbiased women from the general population in Jinan city, 131 PCOS patients and 84 controls from outpatients in Shandong region were studied with questionnaires, physical and pelvic ultrasound examination, body hair on 11 sites were evaluated, and 9 (lip, chin, arm, thigh, chest, upperbelly, lowerbelly, upperback, lowback) of them which were called hormone Ferriman-Gallwey (F-G) score and 2 (forearm, leg) sites of indifferent hormone score were calculated according to the score system described by Ferriman and Gallwey. (1) Both body hair F-G score and indifferent hormone score distribution mode in the <or= 40 years old population were un-normal and both the 95th percentages of score were 2. (2) The hirsutism was significantly higher in PCOS patients [48.1% (63/131)] than in controls [4.8% (4/84)] by F-G score >or= 2 (chi(2) = 47.68, P < 0.01), but no statistic difference by F-G score >or= 6 criterion (chi(2) = 0.64, P = 0.42). (3) F-G scores were declined with age increase. The hair score on the lip, chest, lowerbelly in general population were positively correlated with F-G score (r = 0.712, 0.594, 0.522; P < 0.01) and in PCOS patients (r = 0.879, 0.682, 0.710; P < 0.01), and on the lip in controls (r = 0.950, P < 0.01). (4) The correlation contingency coefficient between hirsutism (F-G score >or= 2) and lip, chest, lowerbelly site in general population was 0.461, 0.420, 0.489 and was 0.560, 0.532, 0.503 in PCOS group respectively. (1) Both body hair F-G score and indifferent hormone score distribution mode are significantly different from Ferriman-Gallwey's report; according to our investigation the suitable criterion of hirsutism for Chinese women in Shandong region should be >or= 2 scores. (2) By F-G score >or= 2 standard, hirsutism is more common in PCOS than in control. (3) Lip, chest, and lowerbelly are the main sites to determine the hirsutism status of women, and the later two sites are more specific for PCOS hirsutism. Forearm and leg score can indicate hirsutism status in some degree but are not specific and sensitive for PCOS hirsutism.

    ABSTRACT: To carry out an epidemiological study of clinical characteristics of Chinese Han ethnic women with polycystic ovary syndrome (PCOS). According to Revised 2003 European Society for Human Reproduction and Embryology/American Society for Reproductive Medicine criteria, PCOS can be diagnosed with 2 manifestations out of oligo-or anovulation, clinical and/or biochemical signs of hyperandrogenism exclusion of other etiologies and polycystic ovaries. One thousand and twenty-seven women in reproductive age from one area in Jinan city were investigated and the clinical, metabolic characteristics of the PCOS patients were analyzed. (1) A total of 828 questionnaires were collected from 1027 women; the response rate was 80.62%. Eighty-five PCOS patients were diagnosed; PCOS accounted for 97.65% (83/85) in <or= 35 years old population groups; (2) Clinical manifestations were different between PCOS groups and controls in each age stage (P < 0.05); Menstruation, body hair Ferriman-Gallny (F-G) score, acne, ovarian follicle numbers decreased with aging among PCOS groups, and menstruation cycle was longer, testosterone (T), free androgen index (FAI) and ovarian follicle numbers were higher, sex hormone-binding globulin (SHBG) was lower than control groups of the same age respectively (P < 0.01); (3) Homeostasis model assessment-insulin resistance (Homa-IR) index in infertility PCOS group was higher than in fertility group (1.49 +/- 0.73 vs 1.31 +/- 0.66; t = 2.058; P < 0.05); fasting insulin, fasting blood glucose in obesity PCOS group was higher than in non-obesity group (8.50 +/- 3.46 vs 5.7 +/- 2.3, t = 2.984; P < 0.01, 5.45 +/- 0.54 vs 4.88 +/- 0.45, t = 2.891; P < 0.01), in contrast, insulin sensitivity index was lower in obesity PCOS group than in non-obesity group (0.025 +/- 0.015 vs 0.044 +/- 0.026; t = 2.292, P < 0.05). (1) PCOS mainly distributes in <or= 35 years old population; (2) clinical manifestations of oligo-ovulation, clinical and/or biochemical signs of hyperandrogenism, polycystic ovaries of PCOS change with age increase. (3) PCOS with infertility and obesity is usually associated with glucose metabolic changes, especially insulin resistance.

    ABSTRACT: To investigate the relationship of (TAAAA)n repeat polymorphism in the promoter of the sex hormone-binding globulin (SHBG) gene and SHBG serum levels to the glucose metabolic status of Chinese polycystic ovary syndrome (PCOS) patients in Shandong province. GeneScan method was used to detect and identify (TAAAA)n repeat number (alleles) and genotypes for 156 controls and 157 patients who were divided into normal glucose tolerance without hyperinsulinemia (NIR group) and with hyperinsulinemia (HI group) and abnormal glucose metabolic (AGM) group according to the results of oral glucose test and insulin resistant test; IRMA was used to measure serum SHBG for part of them. Five alleles containing (TAAAA) 6-10 repeats and 14 genotypes including 6/6, 6/7, 6/8, 6/9, 6/10, 7/7, 7/8, 7/9, 7/10, 8/8, 8/9, 8/10, 9/9, 9/10 repeats genotypes were present in the subjects. Genotype distribution of 6/10 repeats genotype is lower in PCOS than that in control, and 8/9 repeats genotype vice versa (P < 0.01); among PCOS subgroups, the eight repeat genotypes in NIR group is more frequent than that in HI group (P < 0.01), and 7/9 genotype distribution in AGM group is higher than that in NIR group and HI group(P < 0.05-0.01). The serum SHBG levels in homozygous genotype groups exhibit a sequence of 8/8 > 9/9 > 6/6, 7/7 repeats and the fall of serum SHBG trend is in reversed relation with the increase in body mass index (BMI), Homa-IR, and blood pressure. Serum SHBG levels in AGM exhibit a sequence of HI group < NIR group < control but show no statistical difference between both groups. This study reveals that the repeat number, alleles, genotypes and their distributions in Chinese women are very different from these in foreigners. Some special genotypes and low serum SHBG levels may be associated with PCOS and its glucose metabolic status; some special genotypes may influence Chinese serum SHBG and need more studies, but both SHBG gene polymorphism genotype and serum SHBG are not good indicators to find out the PCOS individual at high risk.

    ABSTRACT: To investigate the correlation of 4G and 5G genetypes distribution of plasminogen activator inhibitor-1 (PAI-1) gene polymorphism in its promoter region with polycystic ovary syndrome (PCOS). In 101 Chinese PCOS patients and 42 women as control, 4G and 5G polymorphisms of PAI-1 gene were detected with PCR-restriction fragment length polymorphism (RFLP). Pregnant history, body mass index (BMI), waist-hip ratio (WHR) were collected and Homastasis Model Assessment score for insulin resistant (Homa-IR) and insulin sensitive index (ISI) in PCOS groups were calculated. The distributions of PAI-1 gene polymorphisms 4G type (4G/4G genetype) and 5G type (5G/5G, 4G/5G genetype) were different between the PCOS group and the control. The PCOS group had higher 4G type 57% (58/101) distribution than that of the control group 38% (16/42); 5G type is vise verse (P < 0.05). PCOS patients were divided into obese and non-obese sub-groups according to BMI. There were significant lower Homa-IR and higher ISI in non-obese subgroup than that in obese group (P < 0.05; P < 0.01). 68% (36/53) 4G type distribution in the non-obese is higher than that [48% (23/48)] in obese sub-group (P < 0.05). There were higher 4G type distribution 79% (11/14) and lower 5G type distribution 21% (3/14) in spontaneous miscarriage group than that of in non-spontaneous miscarriage group 38% (5/13) and 62% (8/13) among patients who impregnated at least once (n = 27, P < 0.05). PAI-1 gene polymorphism 4G genetype may be correlated with PCOS in Chinese women, especially in PCOS patients with non-obese PCOS and spontaneous miscarriage.
