National Infrastructure of Chinese Genetic Resources is a part of National Infrastructure of Natural Resources for Science and Technology. To strengthen and standardize the collection, integration, conservation, sharing and utilization of Chinese Genetic Resources, we have been carrying out the research on standardization of trimming, integration and sharing of Chinese Genetic Resources, according the advanced experiences abroad on that and abiding by the related laws and regulations. In the paper, National Infrastructure of Chinese Genetic Resources will be introduced on the standardization of integration, database construction and sharing of Chinese Genetic Resources.

IntroductionWe comprehensively evaluate whether the Chinese Government’s goal of ensuring Universal Health Coverage for essential health services has been achieved.MethodsWe used data from the 2008, 2013 and 2018 National Health Services Survey to report on the coverage of a range of Sustainable Development Goals (SDG) indicator 3.8.1. We created per capita household income deciles for urban and rural samples separately. We report time trends in coverage and the slope index (SII) and relative index (RII).ResultsDespite much lower levels of income and education, rural populations made as much progress as their urban counterparts for most interventions. Coverage of maternal and child health interventions increased substantially in urban and rural areas, with decreasing rich-poor inequalities except for antenatal care. In rural China, one-fifth women could not access 5 or more antenatal visits. Coverage of 8 or more visits were 34% and 68%, respectively in decile D1 (the poorest) and decile D10 (the richest) (SII 35% (95% CI 22% to 48%)). More than 90% households had access to clean water, but basic sanitation was poor for rural households and the urban poorest, presenting bottom inequality. Effective coverage for non-communicable diseases was low. Medication for hypertension and diabetes were relatively high (>70%). But adequate management, counting in preventive interventions, were much lower and decreased overtime, although inequalities were small in size. Screening of cervical and breast cancer was low in both urban and rural areas, seeing no progress overtime. Cervical cancer screening was only 29% (urban) and 24% (rural) in 2018, presenting persisted top inequalities (SII 25% urban, 14% rural).ConclusionChina has made commendable progress in protecting the poorest for basic care. However, the ‘leaving no one behind’ agenda needs a strategy targeting the entire population rather than only the poorest. Blunt investing in primary healthcare facilities seems neither effective nor efficient.

The relationship between females with low glucose-6-phosphate dehydrogenase activity level (LG6PD) and HBV infection is unclear. We conducted a cross sectional study of 124 406 reproductive-age Chinese females who participated in the National Free Pre-conception Check-up Projects to investigate the risk of HBV infection among females with LG6PD and its effect on liver enzyme. Based on HBV serological test results, the participants were divided into the susceptible, immunized, and HBV infected groups. The multivariable-adjusted odds ratios (ORs) for HBV infection in LG6PD participants were 1.71 (95% confidence interval (CI): 1.45–2.01) and 1.41 (95% CI: 1.23–1.62), respectively with the susceptible and immunized participants as references, compared to those without LG6PD. Participants with HBV infection only and combined with HBV infection and LG6PD had 184% and 249% significantly higher risks of elevated alanine transaminase (ALT) (susceptible participants as reference). If the immunized participants were used as reference, significant higher odds of elevated ALT occurred (3.48 (95% CI: 3.18–3.80), 4.28 (95% CI: 2.92–6.28)). Thus, reproductive-age females with LG6PD had a higher prevalence of HBV infection, and LG6PD might exacerbate ALT elevation in HBV infected females. Our findings underscore the need to explore collaborative management approaches for these two diseases among reproductive-age females for maternal and child health.

Objectives: To explore the relationship between body mass index and varicocele, the range of body mass index that leads to increased odds of varicocele, and the association between body mass index with the position and grade of varicocele. Methods: We conducted a cross-sectional study of 211 989 Chinese males aged 18-65 years participated in the National Free Pre-conception Check-up Projects from January 2013 to December 2018. Univariate and multivariate logistic regression models were constructed to assess the association between body mass index and varicocele. Results: Overweight and obese males had 13.1% (odds ratio 0.869, 95% confidence interval 0.838-0.902) and 32.3% (odds ratio 0.677, 95% confidence interval 0.632-0.725) lower odds of varicocele than those with normal body mass index, respectively. The association between them was non-linear, and males with body mass index of 17.74 to 23.09 kg/m 2 had an increased odds of varicocele. The overweight and obese males had lower odds of left and bilateral varicocele, but the right varicocele odds was increased by 63.3% in obese males. Conclusion: Body mass index was associated with the odds of varicocele among reproductive-age males, but the odds varied by position. The effects of weight management and varicocele on fertility should be taken into account in fertility guidance.
