Background Two indexes have been used to describe dietary inflammatory potential: the experiment-based dietary total antioxidant capacity (TAC) and the literature-derived dietary inflammatory index (DII). How robustly each index represents dietary inflammatory potential and the risk of nonalcoholic fatty liver disease (NAFLD) has not yet been established. Objective We investigated the relationship between dietary inflammatory potential and NAFLD and compared the abilities of the TAC and DII scores to predict NAFLD among US adults. Methods Cross-sectional data from 12,410 participants aged 20 -80 years in the National Health and Nutrition Examination Survey (NHANES) from 2011 to 2018 were identified. TAC and DII scores were calculated using 2 days of 24-h dietary recall data. We examined the association between dietary index and risk of NAFLD using linear and logistic regression models. Results Higher energy-adjusted TAC (E-TAC) and inversely energy-adjusted DII (IE-DII) scores (both representing more anti-inflammatory diets) were associated with lower hepatic steatosis index (HSI) and US fatty liver index (USFLI) values after adjusting for potential covariates, and the association for each SD increase in the IE-DII was stronger than the E-TAC (beta estimates for HSI: −0.39 compared with −0.25, P-difference = 0.036). In modeling the risk of NAFLD, we observed that participants with IE-DII scores in the highest quartile had the lowest odds ratios (ORs) for NAFLD as assessed by either the HSI (OR: 0.77; 95% CI: 0.62, 0.96; P-trend = 0.023) or USFLI (OR: 0.48; 95% CI: 0.35, 0.68; P-trend < 0.0001). TAC scores were also associated with NAFLD as assessed by the USFLI. Conclusions An anti-inflammatory diet is beneficial for reducing the risk of NAFLD among US adults. The DII is a stronger predictor of hepatic measures than the TAC and we recommend that future hepatic health studies use the DII to estimate dietary inflammatory potential.

According to the economic and trade cooperation network of the stakeholders of the South China Sea, the paper built a reciprocal network game analysis model based on the reciprocal model. And the influence of national type (the degree of altruism or egoism), the belief in the goodwill of other countries, the correlation between the types of countries and their payments, the social pressure to betrayal given by network neighbors and spillover benefits generated by regional cooperation on the regional economic and trade cooperation in the South China Sea was discussed in depth, and tested with simulation method. The results show that all other factors have positive effects on cooperation, except that the influence of the correlation between the type of country and its payment has two sides. The conclusions of the study provide a reference for the formulation of China's "South China Sea Issue" response strategy.

Abstract:The scientific research is a process in which the researcher apply the scientific knowledge on the practice, and is a link between theory and practice as well. Being the main carrier, the research institutes of some scientific research institution has functions of developing science technology and servicing for society. Every institute has own administration section, which decides whether administration service level update and scientific research achievement application. In this paper, the author discusses the current administration section function based on her work experience, and on the further provides some suggestions to enhance the administration service level in scientific research institutions.
