Objective To investigate the effects and mechanisms of 5-aza-2'-deoxycytidine (5-Aza-CdR) on endometrial cancer cell.Methods In vitro experiments of 5-Aza-CdR were done using human endometrial cancer cell line HEC-1B.Evaluation of cellular proliferation and apoptosis was ascertained respectively using trypan blue exclusion and flow cytometry.RT-PCR and methylation specific PCR(MSP) was done to detect the expression of RASSF1 A mRNA and methylation status of RASSF1 A promoter of HEC-1B cell line.Results (1) The status of cellular growth and apeptosis of HEC-1 B cell line:the growth inhibition effects of 5-Aza-CdR on HEC-1B cell line were both concentration-dependent (P < 0.01) and time-dependent(P <0.01),as well as the apoptosis rate of HBC-1-B cell line depended on the dose of 5-Aza-CdR obviously(P <0.01).(2)The expression of RASSF1A mRNA of HEC-1B cell line:RASSF1A mRNA was expressed in HEC-1B cell after 5-Aza-CdR treatment,but it was undetectable before the treatment.In the groups with different concentration of 5-Aza-CdR (0.05,0.1,1,5,10 nmol/ml),the expression of RASSF1A mRNA was respectively 0.074±0.004,0.105±0.004,0.167±0.006,0.334±0.005,0.484±0.007,which were remarkably different from the group without 5-Aza-CdR(the expression of RASSF1A mRNA was 0;P < 0.01).(3) The hypermethylation of RASSF1A promoter of HEC-1B cell line:the hypermethylation of RASSF1A promoter was detected in HEC-1B cell line.The status of hypermethylation was decreased after treatment with 5-Aza-CdR of 0.05,0.1,1,5 nmol/ml,meanwhile,both methylation bands and demethylation bands were observed by methylation specific PCR.After the treatment with 5-Aza-CdR of 10 nmol/ml the hypermethylation was absent absolutely.Conclusions (1) In HEC-1B cell line,5-Aza-CdR can inhibit cell proliferation and induce cell apopotosis.(2) 5-Aza-CdR can renew the expression of RASSF1A mRNA of HEC-1B cell line and reverse the hypermethylation of RASSF1A promoter.

Objective Investigate the clinicopathological characteristics of h?rthle cell tumors of the thyroid. Methods Sixteen cases of HCT were studied by the clinicopathological study and immunohistochemical and review of the literature. Results There were 13 cases of h?rthle cell adenomas, 5 h?rthle cell follicular carcinomas. Immunostains showed that almost all benign and malignant HCT expressed TG, vimentin, S-100 protein. Conclusions HCT is a potential malignant tumor with a defined pathologic feature. It should be follow up for a longer time to their biological behaviors. To distinguish between the benign and the malignant depends on traditional encapsulation, and whether there is a blood vessel invasion or metastasis.

Objective: To investigate the influence of Icarrin(ICA) on transforming growth factor ?2(TGF?2) expression by PG cells and the mechanisms of reversion of TGF?2 mediated immunosuppression by ICA.Methods: Cell proliferation and cytotoxici- ty were assayed by MTT assay. mRNA level of TGF?2 and perforin was detected by RT-PCR assay. assay.Expression of TGF?2 and IL- 2R? was analysed by folw cytometry assay. Results: ICA could inhibit the protein and mRNA expression of TGF?2 in PG cells. It could also reverse the supressed cytotoxicity of LAK, CD3AK cells by TGF?2. The IL-2R? expression on LAK and perforin gene transcription and proliferation of CD3AK inhibited by TGF?2 were also partly recovered. Conclusion: The anti-anti-tumor activity of ICA is at least partly due to its capability of inhibiting TGF?2 expression in tumor cells and restoring the cytotoxicity of immunocompetent cells inhibited by TGF?2.

Objective To study the expression and clinical significance of serum levels of transforming growth factor-31 (TGF-β1) and tumor necrosis factor-alpha(TNF-α) in patients with hypertensive disorder complicating pregnancy(HDCP).Methods The serum levels of TGF-β1 and TNF-αin 50 cases with HDCP and 30 cases of normal third trimester pregnant women(control group) were detected by ELISA.50 cases with HDCP were divided into gestational hypertension group,mild preeclampsia group and severe preeclampsia group according to the severity of HDCP.Results The serum levels of TGF-β1 and TNF-α in HDCP patients were significantly higher than the control group (t =13.283,13.607,all P < 0.05).The serum levels of TGF-β1 and TNF-α gradually increased with the aggravating of HDCP disease,the serum levels of TGF-β1 and TNF-αwere significantly different among the three subgroups of HDCP(P < 0.05).The correlation analysis showed that the serum levels of TGF-β1,TNF-α were positively correlated with the severity of HDCP (r =0.575,0.512,all P < 0.05),there was significantly positive correlation between the serum TGF-β1 and TNF-α(r =0.515,P <0.05).Conclusion The serum levels of TGF-β1 and TNF-α were high in the HDCP patients,the high levels of TGF-β1 and TNF-α can reflect the changes and development of HDCP disease.The abnormal levels of TGF-β1 and TNF-α may be associate with dysfunction of trophoblast cell.

Transition metal oxide ZnO nanoparticles as inorganic matrix was adopted in the matrix assisted laser desorption ionization time-of-flight mass spectrometry ( MALDI-TOF-MS ) analysis of small molecule compounds including sugars and stearic acid and its performances were investigated. In addition, the feasibility of metal ion selective ionization of L-arginine by using NiO and CuO nanoparticles as matrix directly was explored initially. In the experiment, the analyte and nanoparticle suspension were mixed on the sample plate. The crystal of analyte and matrix was excited by 337 nm laser after the solvent was evaporated, and then detected under reflection mode of TOF-MS. The results indicated that ZnO nanoparticles with high UV absorption could eliminate the interference of conventional matrix, simplify the mass spectra, and enhance the peak intensity of stearic acid under negative mode. Moreover, Cu+ ion selective ionization of L-arginine was achieved in comparison of CuO and NiO as matrix for MALDI-TOF-MS analysis of L-arginine.

Objective To explore the correlation between the serum levels of interferon (IFN)-γ,interleukin (IL)-18,IL-10 and recurrent spontaneous abortion (RSA).Methods Enzyme-linked immunosorbent assay was used to detect the serum levels of IFN-γ,IL-18 and IL-10.There were 40 patients with RSA (RSA group) and 40 normal early pregnant women (control group) enrolled in this study.After 2 months,those serum cytokines in two groups of non-pregnant state were detected again.Results Compared to control group,the serum levels of IFN-γ and IL-18 of RSA group were significantly higher (P <0.01),the serum level of IL-10 was significantly lower (P < 0.01).Two months after termination of pregnancy,there was no significant difference in the serum levels of IFN-γ and IL-10 between the two groups.The serum level of IL-18 maintained a high level in the RSA group after termination of pregnancy.Conclusions In patients with RSA,the serum levels of IFN-γ and IL-18 were elevated,the serum level of IL-10 was decreased.The serum levels of IFN-γ,IL-18 and IL-10 were closely related with RSA.
