Objective: To explore the relationship between serum sex hormone levels and infertility in female patients with pelvic inflammatory disease( PID). Methods: Thirty women with childbearing history who received healthy physical examination in the hospital were selected as control group,seventy infertile women with PID were selected as experimental group; morning fasting blood samples were obtained in the two groups during follicular period; ELISA was used to detect the levels of luteinizing hormone( LH),follicle-stimulating hormone( FSH),estradiol,testosterone,progesterone,and prolactin( PRL). Results: There was no statistically significant difference in serum levels of estradiol and testosterone between control group and experimental group( P > 0. 05); the serum levels of LH and progesterone in experimental group increased significantly,which were statistically significantly higher than those in control group( P < 0. 01); the serum levels of FSH and PRL in experimental group decreased significantly,which were statistically significantly lower than those in control group( P <0. 01). Conclusion: PID affects serum sex hormone levels of women,which indicates than PID is closely correlated with female infertility.

The current situation of reading practice by college students is not optimistic. University and college libraries have not been used to a satisfactory extent and the services by these libraries can not meet the needs of students very well. With some universities and colleges in Xi’an as samples and by using the combination of questionnaires and interviews, this paper investigates the satisfaction of college students’ needs in reading from five aspects which include the expectation for achievements, the expectation for endeavor, the influence of social groups, the related condition and the anxiety during use. Finally it gives some suggestions for the construction of library resources and the services by libraries from the perspective of readers.

Abstract: Because of the deficiency of Chinese Capital Market,the phenomenon of Adverse Selecting and Moral Issues initiated by Principal- Agent problems and Asymmetric information is increasing quickly. So the earnings management problems are more serious. Accounting Conservation and Earnings Smoothness are two important index to measure the quality of accounting information. And the efficiency of investments is a vital factor for a corporation to exist. We use the data of Chinese IT Quoted Corporations to study the effects of the quality of accounting information on the efficiency of investments in Chinese IT quoted corporations. The results are: it is positive correlation between accounting conservation and investment efficiency,and it is negative correlation between earning smoothness. As a result,quoted corporations should improve their accounting quality to increase the investment efficiency.

Objective: To explore the expression and significance of ARHI gene in breast cancer tissue. Methods: Eighty breast cancer tissue samples,forty breast tissue samples adjacent to breast cancer,and twenty normal breast tissue samples were collected,immunohistochemical method and RT-PCR were used to detect the expression levels of ARHI gene in breast cancer tissue,breast tissue adjacent to breast cancer,and normal breast tissue. Results: The expression levels of ARHI protein and ARHI mRNA in breast cancer tissue were statistically significantly lower than those in normal breast tissue and breast tissue adjacent to breast cancer( P < 0. 01),which decreased with the increase of histopathological grades( P < 0. 05); the expression levels of ARHI protein and ARHI mRNA in breast cancer tissue with lymph node metastasis were statistically significantly lower than those in breast cancer tissue without lymph node metastasis( P < 0. 05),but there was no statistically significant difference among breast cancer tissue of different histological types( P > 0. 05). Conclusion: The down-regulation of ARHI gene expression shows that ARHI plays an important role in occurrence and development of breast cancer,which provides a basis for diagnosis and prognosis of breast cancer.

Objective: To explore the expressions of ALDH1 and CD55 protein in normal ovarian tissue,benign ovarian tumor tissue and epithelial ovarian cancer tissue and their relationships with clinicopathological characteristics.Methods: Immunohistochemical method was used to detect the expressions of ALDH1 and CD55 protein in 20 cases of normal ovarian tissue,20 cases of benign ovarian tumor tissue and 60 cases of epithelial ovarian cancer tissue.Results: The expression levels of ALDH1 and CD55 protein in epithelial ovarian cancer tissue was statistically significantly higher than those in normal ovarian tissue and benign ovarian tumor tissue(P < 0.01),which increased with pathological grades and surgical pathological stages(P < 0.05),but there was no statistically significant difference in expression levels of ALDH1 and CD55 protein among tissue of different histological types.Conclusion: The expressions of ALDH1 and CD55 protein have important roles in occurrence and development of epithelial ovarian cancer,which may become new biomarkers of epithelial ovarian cancer,judge biological behavior and predict transfer trend and prognosis of epithelial ovarian cancer.

Objective: To investigate the expressions of TBX2 and P16 protein in cervical squamous cell carcinoma and the relationship with clinical pathological characteristics of cervical cancer.Methods: Expressions of TBX2 and P16 protein in 60 cases of squamous cervical carcinoma,40 case of cervical carcinoma in situ(CINⅢ) and 20 case of adjacent normal cervical epithelium(NCE) were measured by using immunohistochemical technique,relationships between their clinical expressions and cervical squamous cell carcinoma staging, pathological type and lymph node metastasis were analyzed.Results: The positive expression of TBX2 in cervical squamous cell carcinoma, carcinoma in situ and in NCE rates were 86.67%,82.5% and 30%,P16 were 88.33%,87.5% and 0% resprectively.Compared with group NCE,positive expressions of TBX2 and P16 in squamous cell carcinoma and carcinoma in situ of were increased significantly(P < 0.001); the positive expression rates of TBX2 and P16 were relatede with clinical staging,pathological type and lymph node metastasis(P <0.01).TBX2 was positively correlated with P16 expression in cervical squamous cell carcinoma(r =0.66; P =0.039; P <0.05).Conclusion: The expressions of TBX2 and P16 in the tissues of cervical cancer,two cervical cancer,may promote the development of the factors,and to provide evidence for early diagnosis,treatment and prognosis of cervical cancer.
