Dyslipidemia is an important risk factor of atherosclerotic cardiovascular disease (ASCVD). Statins delay the occurrence and development of ASCVD, and reduce the risk of cardiovascular events and death. Due to safety concerns, there exist insufficient use of lipid-lowering agents and a high withdrawal rate of the agents in the elderly. To promote the prevention and treatment of ASCVD, this expert consensus is issued and focuses on the management of dyslipidemia of Chinese elderly basing on the clinical evidence of the use of lipid-lowering drugs by the elderly, and the lipid management guidelines and expert consensus recommendations at home and abroad.

Objective:To explore the expression features of cytochrome C oxidase subunit Ⅰ (MT-CO1), BCL2 interacting protein 3 (BNIP3) and interleukin (IL)-1β in the liver of MRL/lpr lupus mice.Methods:The mRNA and protein levels of MT-CO1, BNIP3, IL-1β, p16 and p21 in lupus mice and control mice were detected by polymerase chain reaction (PCR) and Western blot, the IL-1β expression site were detected by hematoxylin and eosin (HE) staining and immunohistochemical method, and themalondialdehyde (MDA) was detected by colorimetry. Hepatocytes and macrophages were stimulated with lipopolysaccharide (LPS), while hepatocytes were also cultured with supernatants obtained after macrophages stimulated with LPS, and the mRNA and protein levels of MT-CO1, BNIP3 and LC3B, as well as p16 and p21 expression, were determined by qPCR and Western blot. The expression of mitochondrial reactive oxygen species (mtROS) was detected by immunofluorescence. One way Analysis of Variance (ANOVA) was used to compare the mean of each group, and LSD method was used to compare the means of multiple samples, and Tamhane's T2 method was used to compare the means of multiple samples when the variance was uniform. Results:The results of PCR showed that the mRNA levels of MT-CO1 and BNIP3 in the liver tissue of the lupus group (0.14±0.04; 0.16±0.05) were significantly lower than those of the control group (0.11±0.04; 0.16±0.06), and the differences were statistically significant ( t=7.16, P<0.001; t=4.54, P<0.001). The expression levels of IL-1β, p16 and p21 in the lupus group (2.06±0.69; 0.37±0.14; 0.16±0.06) were significantly higher than those of the control group (0.23±0.06; 0.25±0.08; 0.11±0.04) ( t=9.58, P<0.001; t=24.35, P<0.001; t=22.36, P<0.001). The results of Western blot were consistent with those of PCR. HE staining showed lymphocyte infiltration in the liver tissue of lupus mice, and immunohistochemistry showed IL-1β in the liver tissue of lupus mice. The positive cells were mainly concentrated in the sinusoids, and the expression of hepatic parenchymal cells was not rearkable. The content of MDA in liver tissue of the lupus group (0.19±0.10) was higher than that of the control group (0.17±0.09), and the difference was statistically significant ( t=4.33, P=0.005). LPS directly stimulated AML12 hepatocytes (0.069±0.028; 0.17±0.07). The PCR results showed that compared with the control group (0.176±0.072; 0.08±0.03), the expression of MT-CO1, and BNIP3 were not significantly different ( t=1.01, P=0.337; t=0.88, P=0.399). The expression of IL-1β was significantly higher when incubated with the supernatants of LPS stimulated macrophages (0.28±0.09) compared than that of the control group (0.15±0.05) ( t=28.26, P<0.001). The results of PCR showed that the mRNA levels of MT-CO1 and BNIP3 in the LPS stimulated group (0.046±0.026; 0.17±0.05) were significantly lower than those in the control group (0.143±0.083; 0.18±0.06), and the differences were statistically significant ( t=7.52, P<0.001; t=4.24, P<0.001), The expression of p16 and p21 in LPS stimulated group (0.29±0.09; 0.27±0.09) were significantly higher than those in the control group (0.18±0.06; 0.22±0.07) ( t=13.54, P<0.001; t=8.69, P<0.001). The results of Western blot were consistent with those of PCR. Immunofluorescence showed that the fluorescence intensity of mtROS in LPS stimulated group (0.25±0.10) was higher than that in the control group (0.08±0.03), and the difference was statistically significant ( t= 4.86, P<0.001). Conclusion:Immune-mediated inflammation in the liver tissue of lupus mice can stimulate liver parenchymal cells to cause intracellular mitochondrial dysfunction. However, the mechanism of liver organ damage in lupus mice is not limited to the immune-mediated inflammation of immune active cells, but also include parenchymal cell mitochondrial dysfunction.

Objective:To understand the oral health status of urban and rural residents in China,the Fourth National Oral Health Epidemiological Survey (FNOHES) was conducted in 2015.Materials and methods:Based on the principles of multi-stage,stratified,equal capacity,and random sampling,the subjects included five groups of residents aged 3-5,12-15,35-44,55-64,and 65-74 years in all 31 provinces,municipalities,and autonomous regions except Hong Kong,Macao,and Taiwan.The total sample size was 172,425.The survey covered two areas,namely oral health status and knowledge,attitude and oral health behavior.Results:Residents in China had serious caries and poor periodontal condition.The prevalence of caries was above 50％ in all age groups,subjects without periodontal disease accounted for ＜50％,and fewer than 50％ of subjects brushed their teeth twice a day.Based on the results of the FNOHES,the following suggestions were proposed for improving the oral health in China in the future:to establish and improve the comprehensive prevention and control system for oral diseases,implement a comprehensive prevention and control strategy for priority groups,strengthen the oral health education for all people to improve oral health literacy,enhance dynamic monitoring to scientifically evaluate oral health status,and coordinate multi-party resources to establish and improve the oral health service security system.Conclusion:The oral health status of Chinese residents and their oral health behavior habits need to be improved.With the support of the administrative departments of the government and unremitting efforts of the oral health staff,all sectors of society must be coordinated to strengthen oral health education for the whole population.Furthermore,comprehensive prevention and control measures must be implemented for priority groups.

Objective To discuss the present situation and existing problems of the funded projects, especially in the gap between western region and eastern central region by analyzing the funding situation of the projects funded by the National Natural Science Foundation of China (NSFC) and the completed projects in the TCM field from 1989 to 2015. Methods The website was searched thoroughly, and data of Division Ⅹ of Health Science Department of National Natural Science Foundation of China from 1989 to 2015 (ie TCM, Chinese materia medica and integrated traditional Chinese and Western medicine) funded by the National Science Foundation for Young Scientists in China were obtained, and the projects of the National Science Foundation for Young Scientists funded by Division Ⅹ of Health Science Department of National Natural Science Foundation of China from 1989 to 2015 were included, and incomplete or inavailable items were eliminated. Relevant information according to the extracted forms was extracted. The situation of different regions and the situations of the projects have been concluded and the titles of different titles have been analyzed. Results By 2015, the number of funded projects and the amount of financing in the TCM field were increasing year by year. In the western regions, the number of funded projects and the amount of financing accounted for only 11.29% of the total number and 11.28% of the total financing. Compared with the less supporting western regions, much more were mainly in eastern and central regions. The number of SCI papers published and single cited times of the finished projects were 988 and 20.85. Compared with the developed areas in eastern and central regions, there was no statistical significance in the average number of SCI papers (P=0.493), average SCI papers cited article number (P=0.449), SCI papers in average cited frequency (P=0.589), the average CSCD papers number (P=0.579), average CSCD papers cited article number (P=0.883) and average single CSCD papers cited frequency (P=0.753) in western regions (P>0.05). Conclusion Under the stable supports of the Young Scientists Fund, scientific researches in the TCM field have achieved remarkable achievements. In addition, the ability of scientific research and innovation of the young scientific workers have been improved. The funded projects in western regions are far less than those in eastern and central regions, with great differences. However, there is no statistical significance in the research results of the items in western regions and eastern and central regions.

At present, China's AIDS testing increased rapidly, but there are still many people living with HIV do not recognize their status, thus postponing the antiviral treatment time. HIV self-testing (HST) is an effective method to expand the testing, not only simple operation, easy to get a result, effectively protect the detection privacy, expand the selection of testers, suit to the entire population, but also the premise and basis of other AIDS comprehensive prevention measures, all over the world are promoting it. Because the HST has controversies in the window period, price and before and after controversial, and our country is in the initial stage of HST, so it is not to develop related policies, but more and more countries are in accordance with their own situations are modified or developed to allow to use rapid detection of AIDS policy to regulate the field.
