Long-term care is to be one of the issues of common concern to the older persons,with the development process of China's aging population,the older persons with disabilities will become the major groups in the number of disabled population.They need to get more attention by society as they become a class of special groups.Domestic and foreign scholars have conducted a lot of research on the longterm care,the relevant progress are summarized below.

Objective To understand the quality of care for disabled elderly persons in ethnic areas and its influencing factors.Methods A questionnaire survey was carried out using multi-stage stratified random cluster sampling method for the disabled elderly persons in ethnic minority areas,and the relevant factors affecting the quality of care were analyzed.Results The object with different regions,ethnicity,marital status,residence and social support condition,education degrees,health status,the degree of disabilities affecting their life,occupations,income showed different scores in each dimension of care quality.Multiple linear regression analysis showed that other ethnic people with disabilities,unmarried,unemployed/laidoff people with disabilities,disabilities extremely influenced the quality of life affected the total score of care quality.Conclusions To improve the financial aid for disabled elderly people in ethnic areas,attach great importance to the physical and mental care of unmarried disabled elderly people,perfect and establish effective handicapped rehabilitation mechanism,can improve the care quality of disabled elderly people.

Objective To study the schizophrenia and depression recognition rate in the mental health literacy.Methods Search and select the published questionnaire survey studies literature about mental health literacy.Those studies were analyzed by software RevMan 5.2.Results 10 researches entered accorded with the including criteria,a total of 27 275 samples,12 791 of the respondents recognized schizophrenia.10 499 respondents recognized depression.Meta-analysis results showed that the sum of people with schizophrenia recognition rate was 47％ (95％ CI 24％-69％).The sum of people with schizophrenia recognition rate was 45％ (95％CI 31％-59％).Conclusions People from different areas have a higher recognition rate than that of depression.

OBJECTIVE: To explore the role of N~6-methyladenosine(m~6A) catalytic enzymes(methyltransferases and demethylases) in cadmium-induced oxidative damage in human renal epithelial cells(HK-2 cells), and to analyze the correlation between nuclear factor-erythroid 2-related factor 2(NRF2) and m~6A catalytic enzymes. METHODS: i) HK-2 cells in logarithmic growth phase were randomly divided into control group and 6 cadmium sulfate treatment groups, then treated with 0, 2, 4, 8, 16, 32 and 64 μmol/L cadmium sulfate solution for 24 hours. The cell survival rates were detected by CCK-8 assay, and the appropriate doses of cadmium sulfate were selected for subsequent experiments. ii) HK-2 cells in logarithmic growth phase were randomly divided into control group and low-, medium-, and high-dose groups, and treated with 0, 4, 8, and 16 μmol/L cadmium sulfate solution respectively for 24 hours. Subsequently, the levels of reactive oxygen species(ROS) were detected by fluorescence probe. The mRNA expression of NRF2, the m~6A methyltransferases such as methyltransferase like proteins(METTL) 3, METTL14, METTL16 and the m~6A demethylases such as fat mass and obesity associated protein(FTO), AlkB family of nonheme Fe(Ⅱ)/α-ketoglutarate(α-KG)-dependent dioxygenases 5(ALKBH5) were determined by real-time polymerase chain reaction. RESULTS: i) The survival rate of HK-2 cells was more than 60.00% and lower than that of the control group(P<0.05) after the cells were stimulated with 16 μmol/L of cadmium sulfate. Therefore, 4, 8 and 16 μmol/L of cadmium sulfate were selected as the stimulation concentrations in the follow-up experiments. ii) The relative expression of NRF2, METTL3, METTL14 and METTL16 in HK-2 cells in low-dose group increased(all P<0.05), while the levels of ROS and the relative mRNA expression of NRF2, METTL3, METTL14, METTL16 and FTO in HK-2 cells in medium and high-dose groups increased(all P<0.05) when compared with the control group. There was no significant difference in the expression of ALKBH5 mRNA among these 4 groups(P>0.05). In the correlation analysis, NRF2 mRNA expression was positively correlated with the mRNA expression of METTL3 and METTL16 [Pearson correlation coefficient(r) = 0.61 and 0.66, respectively, all P<0.05]. There was no correlation between NRF2 mRNA expression and METTL14, FTO and ALKBH5(r=0.53, 0.48, and 0.01 respectively, all P>0.05). CONCLUSION: Cadmium sulfate may increase intracellular ROS level, up-regulate NRF2 expression and activate NRF2 signaling pathway as well as enhance the expression of METTL3 and METTL16 in HK-2 cells, thus increasing intracellular oxidative damage and decreasing the cell survival rate.
