Objective: To explore the association between sleep duration and the risk of frailty among the elderly over 80 years old in China. Methods: Using the data from five surveys of the China Elderly Health Influencing Factors Follow-up Survey (CLHLS) (2005, 2008-2009, 2011-2012, 2014, and 2017-2018), 7 024 elderly people aged 80 years and above were selected as the study subjects. Questionnaires and physical examinations were used to collect information on sleep time, general demographic characteristics, functional status, physical signs, and illness. The frailty state was evaluated based on a frailty index that included 39 variables. The Cox proportional risk regression model was used to analyze the correlation between sleep time and the risk of frailty occurrence. A restricted cubic spline function was used to analyze the dose-response relationship between sleep time and the risk of frailty occurrence. The likelihood ratio test was used to analyze the interaction between age, gender, sleep quality, cognitive impairment, and sleep duration. Results: The age M (Q1, Q3) of 7 024 subjects was 87 (82, 92) years old, with a total of 3 435 (48.9%) patients experiencing frailty. The results of restricted cubic spline function analysis showed that there was an approximate U-shaped relationship between sleep time and the risk of frailty. When sleep time was 6.5-8.5 hours, the elderly had the lowest risk of frailty; Multivariate Cox proportional risk regression model analysis showed that compared to 6.5-8.5 hours of sleep, long sleep duration (>8.5 hours) increased the risk of frailty by 13% (HR: 1.13; 95%CI: 1.04-1.22). Conclusion: There is a nonlinear association between sleep time and the risk of frailty in the elderly.

OBJECTIVE@#To evaluate the value of high mobility group protein B1 (HMGB1) and soluble receptor for advanced glycation end products (sRAGE) in the diagnosis, efficacy monitoring and prognosis of newly diagnosed multiple myeloma (MM) patients.@*METHODS@#Fifty newly diagnosed MM patients before and after chemotherapy and 50 hematological outpatients from October 2018 to May 2020 were selected. Enzyme linked immunosorbent assay (ELISA) was used to detect the serum HMGB1 and sRAGE levels of the patients. ROC was used to further analyze the efficacy of serum HMGB1 and sRAGE levels on the diagnosis of MM. At the same time, the serum levels of HMGB1 and sRAGE before and after chemotherapy were compared, and their values in the evaluation of curative effect of MM patients were analyzed. According to the mean values of serum HMGB1 and sRAGE, all the patients were divided into different groups, the clinical characteristics and survival status of the patients were compared.@*RESULTS@#Before treatment the serum HMGB1 level of the patients in MM group was higher than that in control group, while sRAGE level was lower (t=11.363,6.127, P<0.001). The AUC of serum HMGB1 and sRAGE in the MM patients was 0.955 and 0.811, respectively. After 3 courses of chemotherapy, HMGB1 level of the patients in CR group was lower than before chemotherapy, while in PD group was higher, as well as sRAGE level of the patients in PR group (P<0.05). There were significant differences in R-ISS stage, HGB, CRP, ESR, CD56, CD117, D13S319 deletion between HMGB1 high expression group and HMGB1 low expression group (χ2=3.920, 6.522, 6.65, 4.16, 3.945, 6.65, 4.16, P<0.05), while there were significant differences in ISS stage, CRP and CD56 between sRAGE low expression group (28 cases) and sRAGE high expression group (22 cases) (χ2=4.565, 4.711, 5.547, P<0.05). Kaplan-Meier survival analysis showed that the patients in HMGB1 low expression group had better survival condition, for PFS Tlow>Thigh (χ2=9.470, P<0.05), and for OS Tlow>Thigh (χ2=7.808, P<0.05); there was no difference in the survival of sRAGE high expression group and low expression group, for PFS Tlow<Thigh (χ2=1.661, P>0.05), and for OS Tlow<Thigh (χ2=2.048, P>0.05). Cox analysis showed that LDH and HMGB1 were the factors affecting the prognosis of the patients, and both of them affected PFS (HR=2.771, 95% CI: 1.002-7.662, P=0.049; HR=6.022, 95% CI: 1.689-21.470, P=0.006), while HMGB1 also affected OS (HR=4.275, 95% CI: 1.183-15.451, P=0.027).@*CONCLUSION@#The serum HMGB1 and sRAGE have certain auxiliary value for the diagnosis and curative effect monitoring of newly diagnosed MM patients, and serum HMGB1 is expected to be an auxiliary detection index for the prognosis of MM.

Objective To study the epidemiological features of the endemic arsenism in Hohhot of Inner Mongolia in 2004-2006 in order to get scientific evidence for the control and prevention. Methods The historical data in Huhhot revealed that 51 arsenic villages in 3 counties(Tumotezuo,Tuoketuo and Helingeer) were investigated. When arsenic content in drinking water was 0.05-0.15 mg/L,the situation of endemic arsenism was investigated in the households having high arsenic contents of water. When arsenic content in drinking water was greater than 0.15 mg/L,the survey was conducted to investigate arsenic patients with census. Census rate was not lower than 90%. Patients of endemic amenism were diagnosed by The Standard of Diagnosis for Endemic Arsenism (WS/T 211-2001). Results A total 28 083 people were examined,3978 were determined to be patients with arsenism,including 1722 being suspicious, 1897 mild,329 secondary and 30 severe. The total incidence of arsenism was 14.17% (3978/28 083),while the incidence of suspicious,mild,secondary and severe disease was 6.13% (1722/28 083) ,6.75% (1897/28 083),1.17% (329/28 083) and 0.11% (30/28 083),respectively. Suspicious and mild patients were most frequently seen. The incidence of dyspigmentation,pigmentation,ketatoses,both dyspigmentation and pigmentation and all of skin disorders was 8.65% (2428/28 083),3.19% (895/28 083),6.48% (1821/28 083),2.13%(598/28 083) and 0.94%(265/28 083),respectively. The most seen skin disorders were dyspigmentation and ketatoses. The disease mostly occurred in those aged over 40 years,the incidence was 89.52% (3561/3978). The incidence of male [15.08%(2209/14 644)]was more than that of female[13.16%(1769/13 439)].Conclusions Current condition of arsenism in Hohhot is mild,arsenic disease surveillance should keep going. Prevention and control needs to be reinforced in the future.
