ObjectiveTo find the mechanism of Heshouwuyin(HSWY) in anti-aging, so as to provide theoretical and experiment evidence for the application of HSWY. Methods50 eight-week female SD rats ( SPF degree)were used in this study. The rats were randomly divided into 5 groups:normal control group, 10 rats; model group,10 rats; HSWY anti-aging group, including low, middle and high dose group,10 rats in each group. The sub-acutely aging rats were made by ip injection of D-galactose for 60 days continually. The rats in HSWY groups were administered with various doses of intragastric HSWYduring D-galactose injection. The parameters of ovary levels of SOD,GSH-PX, TAOC were detected. ResultsThe MDA in ovaries of model rats was significantly higher than that of negative control group;while the SOD, GSH-PX, TAOC of model rats were significantly lower than negative control group.The MDA content in ovaries after taking HSWY was significantly lower than that of model rats; while the SOD, GSHPX,TAOC of the taking HSWY rats was significantly higher than that of model rats. ConclusionThe HSWY could increase antioxida tive activity of rat ovaries to stay D-galactose induced consenescence.

Objective To study the expression and significance of CD10, SMA, P63 on human breast myoepithelial cells. Methods SP immunohistochemical method was used to examine the expression of CD10, SMA, P63 on human breast myoepithelial cells from 68 breast diseases samples, including breast fibroadenoma, breast fibroadenesis, breast atypical ductal hyperplasias, ductal carcinomas in situ and breast invasive carcinomas. Results 2 +/3 + circumferential CD10, SMA and P63 staining of MEC was seen in 10 patients with breast fibroadenoma, breast fibroadenoma and 13 patients with atypical ductal hyperplasias. In an analysis of total ducts by 15 patients with breast ductal carcinomas in situ, 3 + circumfenrential staining was seen in 92 of 384 ducts(23.96%) stained for CD10 versus 185 of 384 ducts (48. 18%) stained for SMA and 80 of 384 ducts(20. 83%) stained for P63. All differences among percentage positively stained of these three antibodies was significant, p-values was lower 0. 05. MECs were not found with immunohistochemistry in 170 of 384 duets (44. 27%)with anti-CD10,74 of 384 ducts(19.27%) with anti-SMA and 127 of 384 ducts(33.07%) with anti-P63. MECs were not found with CD10,SMA and P63 in 30 patients with breast invasive carcinomas. Conclusion We concluded that CDIO could be another useful marker of breast myoepithelial cells after SMA and P63. It provided more sophisticated information about presence or absence of breast myoepithelial cells in confusing breast lesions.

Between 40 to 60, especially after menopause, breast cancer have a higher incidence in women population. CA-153 ( carbohydrate antigen-153 ) is a tumor marker commonly used for monitoring breast cancer in clinic. However, CA-153 appears to have no clinical value for early diagnosis of breast cancer. Gene expression profiling technology becomes hot-spot through which some breast cancer related genes have been found. Moreover, the methods used for diagnosis of breast cancer also has certain shortcomings, and it is still uncertain that breast cancer is likely to be found at the early stage or be predicted in advance.

Objective To study the expression of P450arom(P450A)protein and mRNA in human ovarian endometriosis and normal endometrium and the relationship with its local estrogen abnormal synthesis.Methods PT-PCR was used to assess P450arom messenger RNA(mRNA)expression of 45 ovarian endometriosis and 35 normal eutopic endometrium;immunohistochemical assay was performed to locate and examin the protein expression of P450arom in the above cases.Results P450A mRNA level was higher in the ectopic endometrium than that in eutopic endometrium(P

Objective To analyse the distribution and expression of integrin alpha 6 in eutopic and ectopic endometriosis, and to approach the significance of integrin alpha 6 in this illness. Methods Endometria, focal tissues and fresh tissues were collected from patients with or without endometriosis and normal individuals, respectively. RT-PCR, immunohistochemistry, Western-blot and flow cytometry were employed to assay the distribution and expression of integrin alpha 6 in those collected samples. Results The expression of integrin alpha 6 subunit in proliferative phase and secretive phase has no statistical difference in the patients with or without endometriosis, while the expression of integrin alpha 6 subunit was down-regulated in the ectopic endometrium compared with that in the eutopic counterpart. Conclusion The pathogenesis of endometriosis involves complex regulation of both functions and expression of integrins. The down-regulated expression of integrin alpha 6 in ectopic endometrium may associated with endometriosis.

Objective To investigate the morbidity, clinical characteristics, diagnosis, the pathological classification, character and special behaviour of transformation and the tendency of development of ovarian adenofibroma and cystadenofibroma, so as to provide information for clinical work. Methods 7 patients of ovarian adenofibroma and cystadenofibroma were retrospectively analysed on their onset age, clinical manifestations, ultrasonographic findings, pelvic examination and postsurgical pathology. Results All the seven tumors were serous. The ultrasonography revealed a cystic mass in the overy or near the overy, with clear boundary, and regular in shape. Three tumors were papillary (with rich signal of circulation in the papillary wall in two cases). In one case there was rich circulatory signal in the wall of the cyst. Three tumors had neither papilla on the wall of the cyst, nor blood signal. Pathological examination showed that 4 tumors were benign, and three were borderline. Conclusion The tumor is more prevalent in women of childbearing age. Unilateral tumor is more common than bilateral. The tumor is mainly serous, most of them are benign, and malignant tumors are rare. Ultrasonograply may be helpful to defining the nature and differentiation of the tumor
