ObjectiveTo establish two-dimensional electrophoresis profiles with high resolution and reproducibility from subcellular immortalized human endocervical cell (H8) and cervical cancer cell (Caski), and to identify the differential expressions of subcellular proteins (cytoplasmic, membranous and nuclear proteins). MethodsH8 cells and Caski cells were incubated, and subcellular proteins of H8 cells and Caski cells were extracted and separated by means of immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). Then the selected differential protein spots were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and SWISS-PROT database. ResultsWe obtained well-resolved, reproducible 2-DE patterns; 6 differentially expressed cytoplasmic proteins and 3 differentially expressed membranous proteins and 9 differentially expressed nuclear proteins were defined in 2-DE gels. ConclusionSubcellular proteins of cervical precancerous lesion and cervical cancer are separated and analyzed by means of 2-DE and MALDI-TOF-MS/MS. There are significant differences between H8 cells and Caski cells. These data may be valuable for research of cervical precancerous lesion and cervical cancer, or as diagnostic markers and therapeutic targets for cervical cancer.
ObjectiveTo investigate the health technologies on diabetes prevention and management used in rural China and the assessment results of these health technologies, and to provide references for the selection and using of health technologies on diabetes prevention and management in rural China. MethodsWe searched VIP, CNKI, CBM and WanFang Data to collect survey studies and assessment reports of health technologies on diabetes prevention and management in rural China. The search date was up to July 15th, 2014. Two reviewers independently screened literature, and then the qualitative analysis was performed for the included studies. ResultsA total of 15 studies were included. The results of qualitative analysis showed that:the targeted populations were patients and ordinary villagers who had received the service or treatment of diabetes health technology in rural, as well as the grassroots medical technical personnel and promotion staffs who had developed the health technologies. Diabetes health technology studies in rural mainly included medical personnel health technology related knowledge training. The contents of health technology assessment involved effectiveness, acceptability, economic characteristics, requirements and technical specific property. ConclusionThere was limited researches on the investigation and analysis of health technologies on diabetes prevention and management in rural China, and evaluation content remains insufficient.
