Objective: To understand the core knowledge level and influencing factors of chronic disease prevention and control in Adults in China, and to provide a scientific basis for formulating chronic disease prevention and control measures. Methods: In this study, cross-sectional survey and quota sampling were used to recruit 173 819 permanent residents aged 18 and above from 302 counties of adult chronic diseases and nutrition surveillance in China to conduct an online questionnaire survey, including basic information and core knowledge of chronic diseases. The scores of the core knowledge of chronic disease prevention and control were described by median and interquartile range, the Wilcoxon rank sum test or the Kruskal Wallis test was used for the inter-group comparison, and the correlation factors of the total score were analyzed by the multilinear regression model. Results: A total of 172 808 participants were surveyed in 302 counties and districts, of which 42.60%(73 623) were male and 57.40%(99 185) were female; The proportion of respondents aged 18-44, 45-59, and 60 years old and above was 54.74% (94 594), 30.91% (53 423) and 14.35% (24 791), respectively. The total score of the core knowledge of chronic prevention and control in the total population was 66(13), and the scores of different characteristic groups were different, and the differences were statistically significant: the eastern region had the highest score at 67(11) (H=840.66, P<0.01), the urban 66(12) was higher than the rural 65(14) (Z=-31.35, P<0.01), and the male 66(14) was lower than female 66(12) (Z=-11.66, P<0.01), 18-24 years old 64(13) was lower than other age groups(H=115.80, P<0.01), and undergraduate degree and above had the highest score compared to other academic qualifications, with 68(9) points(H=2 547.25, P<0.01). Multivariate analysis showed that eastern (t=27.42, P<0.01), central (t=17.33, P<0.01), urban (t=5.69, P<0.01), female (t=17.81, P<0.01), high age (t=46.04, P<0.01) and high education (t=57.77, P<0.01) had higher scores of core knowledge of chronic disease prevention and control than other groups, the scores of core knowledge of chronic disease prevention and control of professional and technical personnel (t=8.63, P<0.01), state enterprises and institutions (t=38.67, P<0.01), agriculture, forestry, animal husbandry, fishery and water conservancy production (t=5.30, P<0.01), production, transportation and commercial personnel (t=24.87, P<0.01), and other workers (t=8.89, P<0.01) were higher than those of non-employed people. Conclusion: There are differences in the total scores of the core knowledge of chronic disease prevention and control in different characteristics of people in China, and in the future, health education on the prevention and treatment of chronic diseases should be strengthened for specific groups to improve the knowledge level of residents.

BACKGROUND@#The benefits of healthy lifestyles are well recognized. However, the extent to which improving unhealthy lifestyles reduces cardiovascular disease (CVD) risk needs to be discussed. We evaluated the impact of lifestyle improvement on CVD incidence using data from the China-PAR project (Prediction for Atherosclerotic Cardiovascular Disease Risk in China).@*METHODS@#A total of 12,588 participants free of CVD were followed up for three visits after the baseline examination. Changes in four lifestyle factors (LFs) (smoking, diet, physical activity, and alcohol consumption) were assessed through questionnaires from the baseline to the first follow-up visit. Cox proportional hazard models were used to estimate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs). The risk advancement periods (RAPs: the age difference between exposed and unexposed participants reaching the same incident CVD risk) and population-attributable risk percentage (PAR%) were also calculated.@*RESULTS@#A total of 909 incident CVD cases occurred over a median follow-up of 11.14 years. Compared with maintaining 0-1 healthy LFs, maintaining 3-4 healthy LFs was associated with a 40% risk reduction of incident CVD (HR = 0.60, 95% CI: 0.45-0.79) and delayed CVD risk by 6.31 years (RAP: -6.31 [-9.92, -2.70] years). The PAR% of maintaining 3-4 unhealthy LFs was 22.0% compared to maintaining 0-1 unhealthy LFs. Besides, compared with maintaining two healthy LFs, improving healthy LFs from 2 to 3-4 was associated with a 23% lower risk of CVD (HR = 0.77, 95% CI: 0.60-0.98).@*CONCLUSIONS@#Long-term sustenance of healthy lifestyles or improving unhealthy lifestyles can reduce and delay CVD risk.

Objective To evaluate the effect of serum chromium on oral cancer after adjusting the covarite between groups based on propensity score matching (PSM). Methods We performed a case-control study in 395 cases of newly diagnosed primary oral cancer from the First Affiliated Hospital of Fujian Medical University and 1 240 controls from the same community from January 2010 to February 2018. Using the PSM to select 309 controls randomly which were matched with the cases by 1 ∶1 matching. Conditional Logistic regression model was used to explore the association between chromium and oral cancer. Results The level of serum chromium was 178.91 (121.83-284.19) μg/L in the case group, which was lower than 324.27 (264.82-397.69) μg/L in control group, the difference was statistically significant (P<0.001). Dose-response analysis showed that the risk of oral cancer gradually decreased with the increase of serum chromium, which presented a negative correlation. There was a negative correlation between serum chromium level and the risk for oral cancer by conditional Logistic regression,the aOR of serum chromium in the Q2, Q3 and Q4 compared with the Q1 were 0.14 (0.08-0.26), 0.15 (0.08-0.28) and 0.10 (0.05-0.20),with significant trend (Ptrend<0.001). Stratified analysis showed the negative correlation between serum chromium and oral cancer by smoking, drinking tea, not drinking alcohol status and fish, fruits and green vegetables intake frequencies. Conclusions The high level of serum chromium is a protective factor for the incidence of oral cancer, and the higher of serum chromium, the lower risk of developing oral cancer.

Objective: To analyze the deaths attributable to alcohol use and its impact on people's life expectancy in China in 2013. Methods: The mortality data from the Disease Surveillance Points System and alcohol use data from China Chronic Disease Surveillance (2013) were used. The deaths attributed to alcohol use and its impact on the life expectancy of Chinese residents were estimated based on the principle of comparative risk assessment by calculating population attributable fraction. Results: In 2013, alcohol use resulted in 381 200 deaths, including 97 100 hemorrhagic stroke deaths, 88 200 liver cancer deaths, 61 400 liver cirrhosis deaths and 48 700 esophageal cancer deaths, and prevented 76 500 deaths, including 68 500, 4 900 and 3 100 deaths which might be caused by ischemic heart disease, hemorrhagic stroke and diabetes respectively. If risk factor of alcohol use is removed, the people's life expectancy would rise by an average of 0.43 years, especially in western China by 0.52 years, which was 0.12 years higher than that in eastern and central China, and the life expectancy of the population in rural and urban areas would rise by 0.48 years and 0.31 years respectively. Conclusions: Although alcohol has a protective effect on reducing ischemic heart disease, stroke and diabetes deaths, alcohol use is still a risk factor influencing the mortality and life expectancy of residents in China. It is necessary to take targeted measures to reduce the health problems caused by harmful use of alcohol.

RÉSUMÉ
Endophytes were isolated and purified from the roots of medicinal plant Fengdan also known as Paeonia suffruticosa from Tongling region, Anhui province, China. Morphology and molecular biology methods were applied to indentify the endophyte strains. And methods of growth rate and filtering paper were also used for studying antibacterial/antifungal effects of the strains. As a result, 129 endophyte strains were isolated. Fifty-eight endophytic fungi strains were identified as 6 species in 4 genera and the dominant genus was Fusarium. Seventy-one endophytic bacteria strains were identified as 9 species in 3 genera and the dominant genus was Bacillus. Inhibitory diameter with endophytic fermenting liquid of Pseudomonas chlororaphis, F. nematophilum and B. megaterium from P. suffruticosa against Staphyloccocus aureus, Escherichia coli and B. subtilis reached 25.0,20.2,24.0 mm respectively. The inhibition rate of endophytic fermenting liquid from F. nematophilum against Penicillium sp. and Colletotrichum dematium reached 90.6% and 83.3%, respectively. The inhibition effect of P. chlororaphis against F. oxysporum f. sp. niveum and Mucor sp. was good and the antifungal rate reached 80.0% and 84.9%, respectively. P. suffruticosa in Tongling region contains abundant endophytes. P. chlororaphis and F. nematophilum are valuable species as starting strain about microbicide.
