Additionally,?-mysion heavy chain but not ?-mysion heavy chain expression was observed. CONCLUSION:5-azacytidine induced the differentiation from bone marrow mesenchymal stem cells into myocardial-like cells;in addition,simulated biological microenvironment in both indirect contact group and myocardial cell lysate group also induced the same differentiation. The differentiated cells were cardiac possesses which were between mature cells and cardiac progenitor cells.

Objective To evaluate the effects of ELISPOT (enzyme-link immunospot) test using different samples in diagnosing tuberculous pleurisy. Methods Using T-Spot-TB kit to detect interferon-γlevel in pleural effusion and periph?eral blood from 164 patients with tuberculous pleural effusion and 102 patients without tuberculous pleural effusion. Number of spot forming cells (SFCs) as well as the specificity and sensitivity of the tests were compared between these two methods (ELISPOT using leural effusion or peripheral blood). Results The area under the ROC curve was 0.947 in pleural effusion Elispot test while it was 0.905 in peripheral blood Elispot test. The sensitivity of pleural effusion ELISPOT test in diagnosis of tuberculous pleurisy (95.1%) was significantly higher than that of peripheral blood ELISPOT test (89.0%). What’s more, the specificity of pleural effusion ELISPOT test in diagnosis of tuberculous pleurisy (90.2%) was higher than that in diagno?sis of peripheral blood ELISPOT test (88.2%). Conclusion The pleural effusion ELISPOT test is more valuable than periph?eral blood ELISPOT in the diagnosis of tuberculous pleuritis.

Objective: To compare the advantages and disadvantages of three staining methods of HBV. Methods: Normal Liver tissue and HBV-infected, HCV-infected ,or dually infected (HBV and HCV) liver tissues were selected for this study. Formalin- fixed, paraffin-embedded sections(4 ?m) were prepared. Each of the liver tissue specimens was detected by three staining methods, including immunohistochemical methods ,Shikata’s orcein stain and Victoria blue stain,respectively. Results: In the three methods , all of six HBV -infected cases showed intense staining, and three cases with dual infection (HBV and HCV) were weakly positive. However, both normal and HCV-infected liver tissues showed no staining. HBsAg stained dark brown with Immunohistochemical stain; HBsAg containing ground-glass hepatocytes stained magenta with Shikata’s orcein stain; HBsAg stained blue with Victoria blue. Conclusion: Each of three methods has its own advantages and disadvantages: high specificity and sensitivity, but high cost for immunohistochemical methods;complicated and overelabrate procedure for preparation of solutions, lower specificity and sensitivity,but low cost, for special staining methods.

BACKGROUND:Cholesterol is closely linked to the occurrence and progression of atherosclerosis. Current approaches to study celular cholesterol dynamics have their own limitations.
OBJECTIVE: To measure the cholesterol efflux rate of RAW 264.7 mouse macrophages by BODIPY-Cholesterol labeling and to explore the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.
METHODS:RAW 264.7 cels were cultured in vitro with DMEM containing 10% fetal bovine serum, and labeled with BODIPY-Cholesterol for 1, 2, 4, 8 hours. Then, the cels were rinsed with serum-free DMEM and inoculated for 6, 12, 24, 48, 96 hours to optimize the labeling time and incubation time. We measured and compared the cholesterol efflux rates after cultured cels were treated with cholesterol, lipopolysaccharide, human sera with high cholesterol or human sera with normal cholesterol.
RESULTS AND CONCLUSION: The best labeling time for BODIPY-Cholesterol was 2-8 hours. Cholesterol efflux rates were gradualy decreased after the cels that were labeled for 2 hours were incubated with increasing concentrations of cholesterol (0.1, 0.5, 2.5 mmol/L,P< 0.01). Treating cels with lipopolysaccharide also decreased the cholesterol efflux rate (P < 0.05). Furthermore, the cholesterol efflux rate was decreased after cels were treated with human sera with high cholesterol (P< 0.05). These findings indicate that BODIPY-Cholesterol can be used to measure celular cholesterol efflux rate and to study the effects of extracelular cholesterol and lipopolysaccharide on the cholesterol efflux rate.

Objective:To explore the expressions of miRNA-17-92 (miR-17-92) cluster and mitofusin 2 (MFN2) protein in endometrial cancer (EC) and their clinical significances.Methods:A total of 72 EC tissues, 36 endometrial lesions of patients with endometrial atypical hyperplasia, and 22 normal endometrial tissues from total hysterectomy for grade Ⅲ cervical intraepithelial neoplasia in the Second Affiliated Hospital of Shandong First Medical University from January 2008 to December 2014 were collected; at the same time, all patients' paraffin-embedded tissues were collected. Real-time quantitative polymerase chain reaction was used to detect the expression level of miR-17-92 in each tissue. Immunohistochemical SP method was used to detect the localization and expression level of MFN2 protein in each paraffin-embedded tissue. The correlation of miR-17-92 and MFN2 protein with clinicopathological features of EC patients was analyzed. Kaplan-Meier method was used to draw survival curve of patients with different miR-17-92 and MFN2 levels, and log-rank test was made; Cox proportional hazard regression model was used for multivariate survival analysis.Results:The relative expression of miR-17-92 in EC, atypical hyperplasia and normal endometrial tissues were 1.49±0.46, 1.01±0.30 and 0.69±0.20, respectively. The expression of miR-17-92 in EC tissues was higher than that in the other endometrial tissues, and the differences were statistically significant (both P < 0.01). The high-expression rates of MFN2 protein in EC, atypical hyperplasia and normal endometrial tissues were 20.8% (15/72), 39.4% (13/33) and 85.0% (17/20); the high-expression rate of MFN2 protein in EC tissue was lower than that in the other endometrial tissues, and the differences were statistically significant (both P < 0.012 5). In EC patients, the relative expression of miR-17-92 in patients with histological type Ⅱ was higher than that in patients with histological type Ⅰ ( P < 0.05); the relative expression of miR-17-92 in patients with myometrial invasion depth ≥1/2 were higher than that in patients with myometrial invasion depth <1/2 ( P < 0.05). The high-expression rate of MFN2 protein in patients with histological type Ⅰ was higher than that in patients with histological type Ⅱ ( P < 0.05); the high-expression rate of MFN2 protein in patients with International Federation of Gynecology and Obstetrics (FIGO) grade Ⅰ was higher than that in patients with FIGO grade Ⅱ and Ⅲ ( P < 0.05). When the EC patients were grouped according to the median relative expression of miR-17-92 (1.421), Kaplan-Meier survival analysis showed that the median overall survival (OS) time of the miR-17-92 low-expression group (36 cases) was not reached, and the high-expression group (36 cases) was 36 months (95% CI 32-42 months), and the difference in OS between the two groups was statistically significant ( P = 0.049); the median OS time of the MFN2 high-expression group (15 cases) was not reached, and the low-expression group (57 cases) was 38 months (95% CI 33-41 months), and the difference in OS between the two groups was statistically significant ( P = 0.046). Multivariate Cox regression analysis showed that the expression levels of miR-17-92 and MFN2 were independent influencing factors for the survival of EC patients ( HR = 3.10, 95% CI 1.36-7.07, P = 0.007; HR = 0.30, 95% CI 0.09-0.99, P = 0.048). Conclusion:The high-expression of miR-17-92 and low-expression of MFN2 protein in EC tissues may be involved in the occurrence and development of EC, and they can be used as indicators for judging the prognosis of EC patients.

Objective To investigate the association between the genetic polymorphisms in GSTA1 and the clinical outcome of breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy. Methods A total of 137 breast cancer patients receiving cyclophosphamide-based adjuvant chemotherapy were recruited ( 124 cases with infiltrative ductal carcinoma, 5 cases with infiltrative lobular carcinoma and 8 cases with other histological types). PCR-LDR method was used to detect the genotypes of GSTA1. Survival curves were generated by the Kaplan-Meier method, and verified by the log-rank test. Cox proportional hazards regression analysis was used to estimate the prognostic factors in multivariate analysis. Results Of the 137 breast cancer patients, the genotypic frequencies of the GSTA1 * A/* A,* A/* B and * B/* B were 67.2% ( 92/137 ), 31.4% ( 43/137 ) and 1.5% ( 2/137 ), respectively. No significant differences were found between the genotypic frequencies and groups categorization according to age, stage, lymph node metastasis, ER or PR status (x2 = 0. 722,1. 967, 3. 303, 0. 226 and 0. 709, all P ＞0. 05 ) ;through Fisher exact test, also no significant differences were found between the genotypic frequencies and group categorization according to tumor size, histological types and grading ( all P ＞ 0. 05 ) . The recurrence rates in patients with GSTA1 * A/* A and * A/* B or * B/* B genotypes were 47. 8% (44/92) and 31.1% ( 14/45 ), respectively, and the mortality rates were 22. 8% ( 21/92 ) and 17. 8% ( 8/45 ),respectively. Patients with GSTA1 * A/* B and * B/* B genotypes were significantly associated with reduced hazard of relapse (x2 =18.723, P＜0. 01)and mortality (x2 =7.352, P＜0.01), compared to cases with the common * A/* A genotypes, according to Kaplan-Meier survival analysis and log-rank test. Moreover,Cox multivariate analysis showed that GSTA1 polymorphisms appeared to be an independent risk factor for recurrence-free survival ( OR =0. 222, 95% CI:0. 108-0. 458, P ＜0. 01 ) and overall survival ( OR =0. 362,95% CI:0. 145-0. 902, P ＜ 0. 05 ). Conclusion These data indicate that GSTA1 polymorphism may be a potential prognostic factor for recurrence-free survival and overall survival in breast cancer patients treated with cyclophosphamide-based adjuvant chemotherapy.
