Objective:This work aims to detect the levels of miR-200c/141 methylation and miR-200c/141 in gastric cancer tissue and investigate the relationship between miR-200c/141 expression and clinical parameters. Methods:The methylation status of miR-200c/141 CpG island and miR-200c/141 in gastric cancer tissue specimens was evaluated by qRT-PCR or BS-MSP method. We analyzed the relationship among the methylation status of miR-200c/141 CpG island, expression level of miR-200c or miR-141, and clinical parame-ters. Results:The status of miR-200c/141 CpG island methylation in gastric cancer tissue was significantly higher compared with that in paracarcinoma tissue. MiR-200c and miR-141 were markedly decreased in gastric cancer tissue compared with those in adjacent tis-sue. MiR-200c/141 CpG island methylation was negatively related with the expression of miR-200c and miR-141 in gastric cancer speci-mens. Conclusion:The upregulation of miR-200c/141 CpG methylation inhibits miR-200c/141 expression in gastric cancer tissue.

Objective To observe the safety and effectiveness of high-dose chemotherapy(HDT) supported by autologous peripheral blood hematopoietic stem cells transplantation(APBHSCT) in the patients of terminal or relapsed malignant tumors.Methods The patients achieved CR or PR after 4 cycles of conventional salvage chemotherapy were divided into two groups randomly.26 patients in the research group were adapted APBHSC+HDC,50 patients in the control group were adapted 2～4 cycles of routine chemotherapy.Results In the research group,hematopoiesis was reconstructed in all patients,8 out of 17 patients who achieved PR after 4 cycles of conventional salvage chemotherapy turned into CR after APBHSC+HDC(CR rate 47.1%).In the control group,33 patients who achieved PR after 4 cycles of conventional salvage chemotherapy were still PR after 2～4 cycles of routine chemotherapy.The median survival period in the research group was 11 months,which was longer than the one in the control group.The survival rates of 2,3 and 4 years in the research group were evidently higher than the ones in the control group(P

Objective Survey of Guangxi Traditional Chinese Medicine hospital hand hygiene facilities at all levels was made with improvement measures proposed.Methods Hand Hygiene Norms for Medical Workers questionnaires designed by the Ministry of Health was used in a field survey on hand hygiene facilities of 89 TCM hospitals in Guangxi.Results Facilities of the non-hand-touch taps,hand sanitizer and hand disinfectants were found satisfactory at key departments at all TCM hospitals in the region,yet poor performance with the hand drying facilities.Hospitals with such departments with non-hand-touch taps,hand sanitizer and hand disinfectants accounted for 93.3％,100.0％ and 100.0％.Only 41.6％ of the hospitals were found to use dry hand towels as drying facilities.Significant difference was found at various levels of hospitals' hand hygiene facilities.Conclusion The hand hygiene facilities at such hospitals in Guangxi are receiving growing attention,yet further investment is still required for further improvement and compliance of the medical staff in hand hygiene.
