- Current Chinese national guidelines recommend routine screening for liver cancer in patients positive for HBsAg, irrespective of fibrosis status, age, or family history of liver cancer. We aim to evaluate whether the recommended screening strategy could reduce liver-cancer-specific mortality. We conducted a liver cancer mass screening trial in Xiaolan Town, Zhongshan City, China, among residents aged 35–64 years in 2012. All volunteers were offered serological testing for hepatitis B virus surface antigen (HBsAg). We proposed biannual screening using serum alpha-fetoprotein (AFP) and ultrasonography examination for subjects positive for HBsAg. Among 17,966 participants (26.2% of 68,510 eligible residents) who were free of liver cancer at baseline in 2012, we identified 57 incident cases of liver cancer within the first 4 years of follow-up (i.e., 43 among 2,848 HBsAg-positive participants and 14 among 15,118 HBsAg-negative participants), compared with 104 cases identified in non-participants (N = 50,544). A total of 207 participants had the recommended number of ultrasonography examinations (every 6 months) during the screening period. Compared with cases identified from non-participants, the cases arising among participants were more likely to be at early stage and had better survival than those among non-participants. However, we did not observe a reduction in liver cancer-specific mortality rate among participants (relative risk = 1.04, 95% confidence interval = 0.68, 1.58, P = 0.856). Our demonstration screening study does not show a reduction in liver cancer mortality within the first 4 years of follow-up according to current guidance in China, although long-term efficacy remains to be evaluated. Targeted surveillance among high-risk individuals as recommended by international guidelines, along with measures to improve compliance, should be evaluated in the Chinese population.

- To develop and validate a midwifery-led task list in the task-shifting context.DesignAn extensive literature review followed by a two-iterative Delphi survey.SettingTwenty university hospitals, three non-university hospitals and four university colleges from nine provincial regions of China.ParticipantsPurposive non-probability sampling of a national panel of experts in maternal healthcare, obstetrics, nursing and midwifery. Experts in the panel were asked to rate each midwifery service item regarding importance, feasibility and advancement on a 5-point scale, in order to determine those best suited for midwifery-led practice in China.ResultsTwo rounds of Delphi surveys were completed before consensus was achieved, with effective response rate ranging from 96.4% (27/28) to 100% (27/27), indicating a high positive coefficient of the experts. The authority coefficient of experts was 0.882, indicating the high reliability of this study. The Kendall harmony coefficient (W) in the two rounds of consultations was 0.196 (p<0.001) and 0.324 (p<0.001), respectively. A detailed, three-level midwifery-led task list was developed, including 3 domains of midwifery practice (first-level indicators), 13 types of task (second-level indicators) and 58 midwifery service items (third-level indicators). The 3 domains of midwifery practice involved the appropriate scope of practice for Chinese midwives, including antenatal care, intrapartum care and postnatal care. The 58 service items embraced core components of caring task in the Chinese midwifery profession.ConclusionThis study outlines the first midwifery-led task list that defines clearly the Chinese midwives’ scope of practice. It will provide a foundational framework for future midwifery practice in China and abroad, and can be used to inform the design of midwifery-led task shifting interventions in various maternity settings.

- The strong genetic contribution of the major histocompatibility complex (MHC) region to rheumatoid arthritis (RA) has been generally attributed to human leukocyte antigen (HLA)-DRB1. However, due to the high polymorphisms and linkage disequilibrium within MHC, it is difficult to define novel and/or independent genetic risks using conventional HLA genotyping or chip-based microarray technology. This study aimed to identify novel RA risk variants by performing deep sequencing for MHC.MethodsWe first conducted target sequencing for the entire MHC region in 357 anticitrullinated protein antibodies (ACPA)-positive patients with RA and 1001 healthy controls, and then performed HLA typing in an independent case–control cohort consisting of 1415 samples for validation. All study subjects were Han Chinese. Genetic associations for RA susceptibility and severity were analysed. Comparative modelling was constructed to predict potential functions for the newly discovered RA association variants.ResultsHLA-DQα1:160D conferred the strongest and independent susceptibility to ACPA-positive RA (p=6.16×10−36, OR=2.29). DRβ1:37N had an independent protective effect (p=5.81×10−16, OR=0.49). As predicted by comparative modelling, the negatively charged DQα1:160D stabilises the dimer of dimers, thus may lead to an increased T cell activation. The negatively charged DRβ1:37N encoding alleles preferentially bind with epitope P9 arginine, thus may result in a decreased RA susceptibility.ConclusionsWe provide the first evidence that HLA-DQα1:160D, instead of HLA-DRB1*0405, is the strongest and independent genetic risk for ACPA-positive RA in Han Chinese. Our study also illustrates the value of deep sequencing for fine-mapping disease risk variants in the MHC region.
