The Intervention Effect of Rosiglitozone in Ovarian Fibrosis of PCOS Rats

Objective To explore the Intervention effect of Rosiglitozone in ovarian fibrosis of PCOS rats. Methods 60 female SD rats were randomly divided into 3 groups： control group, model group and treatment group. The model and treatment groups were established by subcutaneous injection of DHEA, while the treatment group was given RGZ. The serum hormone values, pathohistology of ovarian structure of rats, ovarian ultrastructure and the expressions of TGF-β1 and CTGF were detected. Results The PCOS model was established successfully. The expression intensity of TGF-β1 and CTGF in Oocytes of the PCOS groups was 9.545±2.954 and 9.665±2.400, respectively and was significantly higher than that of the control group 6.636±2.264 and 7.036±2.133; after treatment with rosiglitazone, the expression was significantly decreased 6.980±2.421 and 6.642±2.721 as compared with that of the model group （P〈0.05, P〈0.001）. The values in serum of the PCOS groups were 3.749±2.054 and 0.265±0.129, and 1.914±1.801 and 0.096±0.088 in the control group which had statistically significant difference （P〈0.05, P〈0.O01）. After treatment with rosiglitazone, the values were 2.3100±1.825 and 0.112±0.187 and were significantly different with those of the model group （P〈0.05, P〈0.O01）. Conclusion TGF-β1 and CTGF play an important role in the development of ovary fibrosis in PCOS. However, RGZ may postpone the development of fibrosis by decreasing the levels of TGF-β1 and CTGF.

Role of TGF-β_1 in the Formation of Ovarian Interstitial Fibrosis in PCOS Rat

Objective To study the role of TGF-β1 in the formation of interstitial fibrosis and capsular thickening in the PCOS rats.Methods PCOS rat model were established by subcutaneous injection DHEA. Estradiol （E2）, testosterone （T）, follicular stimulating hormone （FSH）, luteinizing hormone （LH）, LH/FSH and fasting insulin （FINS） hormone values of the model were tested by microparticle enzyme immunoassay, the pathohistology of PCOS rat ovaries was observed by HE staining, and their ultrastructure was tested by transmission electron microscope （TEM）. The expressions of TGF-β1 in PCOS group （n =20）, and control group（n=20） were detected and evaluated by immunohistochemistry and image analysis system.Results The results of serum E2, T, LH/FSH, FINS, the ovarian pathological-histology and the ultrastructure showed that the model was established successfully. Compared with control group： there was no significant difference of TGF-β1 expression intensity in oocytes, granulosa cells of the different developing stages of follicle in PCOS （P〉0.05）. But it was markedly higher expressed in the theca cells of antral follicles （P〈0.01）, and stromal cells （P〈0.05） in PCOS group than in control group.Conclusion The abnormal expression of TGF-β1 in PCOS is the main cause of capsular thickening and interstitial fibrosis. TGF-β1 also takes part in regulating PCOS follicle development and atresia.

Change of Accessory Genital Glands Markers in the Patients with Oligoasthenospermia

Objective To evaluate the effect of the accessory gential gland on the male fertility. Methods The relevant seminal parameters of 32 normal donors and 35 patients with olioasthenospermia were measured by seminal routine analysis, sperm morphology and accessory, gentital glands markers.Results The percentage of normal spermatozoa, the function of sperm penetration through cervical mucus and the enzyme activity of neutral α-1,4-glucosidase significantly declined as compared with the control. There was a significant negative relationship between the semen volume and the sperm motility for the oligoasthenospermia （r= -0.415, P〈0.05）, and a significant positive relationship between the sperm count and the percentage of normal sperm （r=0.393, P〈0.05）.Conclusion The abnormal function of epididymis exists in patients with oligoasthenospermia. Sperm function,for the oligoasthenospermia declines with an increase of the percentage of the abnormal sperm. The poorer the spermatogenises function of the testis is, the higher the percentage of the abnormal sperm appears.
