Project description:Objective:This study evaluated the feasibility of different cervical cancer screening strategies in urban China. Methods:A Markov model was constructed to simulate a hypothetical cohort of 100,000 females aged 30-59 years in a 20-year period. Screening strategies included liquid-based cytology (LBC) every three years, human papillomavirus (HPV) DNA testing every three and five years, respectively, and a combination of HPV DNA testing and LBC (HPV+LBC) every three and five years, respectively. Model outcomes included cumulative incidence over 20 years, cumulative risk of cervical cancer, costs, life year saved (LYS), quality-adjusted life years (QALYs) and benefits. The cost-effectiveness ratios (CERs), incremental cost-effectiveness ratios (ICERs), cost-utility ratios (CURs), and benefit-cost ratios (BCRs) were used as outcomes in the health economic evaluation analysis. Univariate sensitivity analyses were performed to examine the stability of the results. Results:The cumulative incidence of the five screening strategies ranged from 833.02 to 1,158.07 cases per 100,000 females. HPV DNA testing was most effective in reducing the cumulative risk of cervical cancer, saving life years and QALYs and gaining benefits. The CERs of HPV DNA testing every three and five years, and LBC every three years were considered to be very cost-effective if they were below China's GDP per capita. The CERs of HPV+LBC were considered to be cost-effective if they were below three times GDP per capita. The incremental cost-effectiveness analysis showed that HPV DNA testing every three and five years, LBC every three years and HPV+LBC every five years were dominant strategies. Conclusions:The findings of this study indicated that HPV DNA testing every five years or LBC every three years should be recommended in urban China.

Project description:The purpose of the this study is to determine the prevalence of germline cancer susceptibility gene mutation among Chinese population, and to find best ways to screen patients with colorectal cancer in China. To accomplish this objective, the investigators will establish a large sample database of hereditary colorectal cancer related information using multigene panel testing based on Next-Generation Sequencing.

Project description:Second generation sequencing technology has enabled the design of large-scale sequencing experiments in targeted disease-related regions in thousands of cases and controls. Cost implications dictate a pooled DNA sequencing design, evaluation of allele frequency differences based on the resequenced samples and large-scale targeted follow-up in further samples. To evaluate the feasibility of this approach and to assess different study design strategies, we have carried out a pilot study which tests the feasibility of PCR-based and pull-down DNA pooling for (a) SNP discovery and (b) allele frequency comparison purposes. All samples are from the HapMap or 1958 BC. The sample composition of the pool is listed below: Pool 5: 31 HapMap Individuals (NA12249, NA12156, NA12004, NA11831, NA12716, NA11832, NA11993, NA12057, NA11995, NA12006, NA12144, NA12802, NA12146, NA12005, NA12003, NA07000, NA12043, NA12044, NA11992, NA11881, NA11994, NA07345, NA12154, NA06994, NA06985, NA12239, NA07022, NA07034, NA12155, NA07056, NA06993); 19 1958 BC Individuals (WTCCC88214, WTCCC88215, WTCCC88216, WTCCC88217, WTCCC88222, WTCCC88233, WTCCC88240, WTCCC88241, WTCCC88242, WTCCC88247, WTCCC88249, WTCCC88262, WTCCC88264, WTCCC88278, WTCCC88294, WTCCC88298, WTCCC88302, WTCCC88305, WTCCC88321) Some pools were carried out in duplicate to assess reproducibility. We focused on 10 (PD), 7(PCR) chromosomal regions, ~2(PD), ~1.6 (PCR) Mb in total.

Project description:An archaeological bone fragment from Baishiya Karst Cave, China, was identified as stemming from a hominin through ZooMS (Zooarchaeology by Mass Spectrometry). Shotgun palaeoproteomic analyses were thereafter conducted on the specimen to refine the taxonomic identification and perform phylogenetic analyses. The reconstruted proteome shows that the newly described Baishiya Karst Cave individual, Xiahe 2, is most closely related to the high-coverage published genome from a Denisovan individual.

Project description:We evaluated the expression of known human miRNAs in human hepatocellular carcinoma (HCC) and normal hepatic tissues from southeast China, and identified the differentially expressed miRNAs in HCC tissues. We use microRNA array platform from CapitalBio Corp. to access the miRNA expression profiles in HCC and non-tumor liver samples from Southeast China. There were 5 HCC samples and 3 non-tumor liver samples in our study. As the microarray platform we used was based on a older version of miRBase, we mapped the probe sequences to a newer version of miRBase before these data was applied to further analysis.

Project description:Mass spectrometry-based glycoproteomics studies now routinely report thousands of intact glycopeptides. Diverse informatics solutions aiding the challenging glycopeptide identification process have recently appeared, but their strengths and weaknesses have not been established leaving a critical knowledge gap that prevents rapid progress in the field. This interlaboratory study comprising both expert users (13 teams) and developers (9 teams) of glycoproteomics software is the first to evaluate the relative performance of current informatics solutions for accurate and comprehensive N- and O-glycopeptide identification. Two LC-MS/MS datasets of intact glycopeptides from serum proteins were shared with all teams. The relative team performance for large-scale glycopeptide analysis was systematically established through 11 orthogonal performance tests based on the assigned spectra reported by each team. This study has found that a diversity of approaches exists for comprehensive glycopeptide data analysis, has demonstrated the team-to-team (vari)ability of identifying intact glycopeptides from shared datasets, and, importantly, has revealed several high-performance informatics solutions and search strategies that will be useful to improve the challenging glycoproteomics data analysis in the immediate future.
