Objective:To investigate the prevalence and influencing factors of amnestic mild cognitive impairment of rural elderly in Guizhou province, which aims to provide scientific basis for the prevention and control of cognitive impairment in the elderly.Methods:Adopting a multi-stage cluster sampling method, a total of 1 535 rural Han and Bouyei elderly people aged 60 and above were selected from Guiyang city and Qiannan prefecture in Guizhou province as the survey subjects for the current situation survey, including demographic sociological characteristics, such as social was utilized behavior, social behavior disease history, height and weight and so on.Mini-mental state examination was utilized to measure cognitive function and SPSS 26.0 statistical software was used to perform χ 2 inspection and multivariate unconditional Logistics regression analysis to calculate odds ratio ( OR) and 95% confidence interval (95% CI). Results:A total of 242 elderly patients with aMCI were detected (15.8%). The results of univariate analysis showed that ethnicity(χ 2=4.333, P<0.05), gender(χ 2=18.367, P<0.01), marital status(χ 2=9.721, P<0.01), occupation(χ 2=7.786, P<0.01), annual family income(χ 2=28.085, P<0.01), current smoking(χ 2=11.873, P<0.01), specific hobbies(χ 2=25.968, P<0.01), physical exercise(χ 2=11.871, P<0.01), living style(χ 2=13.190, P<0.01), and activity participation(χ 2=13.004, P<0.01) all had an impact on aMCI. Multivariate Logistic regression analysis showed that Bouyei nationality( P<0.05, β=0.288, OR=1.333, 95% CI=1.002-1.775) and the women( P<0.05, β=0.516, OR=1.676, 95% CI=1.233-2.278)were risk factors for aMCI, and high annual family income( P<0.05, β=-0.839, OR=0.432, 95% CI=0.308-0.606), specific hobbies( P<0.05, β=-0.580, OR=0.560, 95% CI= 0.394-0.795), physical exercise( P<0.05, β=-0.410, OR=0.664, 95% CI=0.493-0.894), participation in activities( P<0.05, β=-0.424, OR=0.654, 95% CI=0.488-0.877), and non-living alone( P<0.05, β=-0.563, OR=0.569, 95% CI= 0.374-0.866) were the protective factors.Comparison of the prevalence of the disease between the Han and Bouyei nationalities, the detection rate of aMCI for the Bouyei elderly (18.0%) was higher than that of the Han (14.1%) (χ 2=4.333, P<0.05). After stratification according to gender, family annual income, specific hobbies, physical exercise, participation in activities and living style, the detection rate of elderly female subjects of Bouyei nationality was higher than that of Han nationality, whose difference was statistically significant (χ 2=5.562, P<0.05). The detection rate of Bouyei elderly was higher than that of Han when the annual household income was less than 30 000, and the difference was statistically significant (χ 2=8.570, P<0.01). Conclusion:The incidence of aMCI among the elderly of Bouyei nationality is higher, and the incidence of aMCI among females is higher than that of males, which should be paid more attention to.It is of vital importance to strengthen health education and publicity, guide the formation of knowledge-belief-behavior health-related behavior patterns, so as to improve the quality of life and reduce the risk of cognitive impairment.

Objective To study the 137Cs source term from the Fukushima Daiichi nuclear power plant,based on inverse modeling,so as to provide reference for accident assessment and radiation protection.Methods The 137Cs source term was estimated by means of inverse modeling of nuclear accidents based on variational data assimilation combined with truncated total least squares (TTLS-VAR).The environmental monitoring data was balanced,and the dispersion model operator and monitoring data vector were corrected,in order to reduce the influence from atmospheric dispersion model error,and then improve the accuracy of inverse modeling of source term.Results The total amount of 137Cs released was estimated to be 1.74× 1016-3.73× 1016 Bq,with the highest peak of release rates estimated appearing on March 18,2011 and the average release rate in exceed of 1.00× 1012 Bq/s.The estimated total amount of 137 Cs was close to the data published by IAEA and UNSCEAR.Also,the estimated release sequences were in good consistent with Japanese analytical results of source terms and sequence of events.The highest peak of the estimated release rate curve corresponds to the leakage incident of unit 3.Conclusions In this study,the 137Cs source term from the Fukushima Daiichi nuclear power plant is estimated by using TTLS-VAR inverse modeling,which could provide the basis for accident assessment and radiation protection.

Objective To investigate the compliance of follow-up and the associated factors of diabetic retinopathy screening among diabetes patients in Muping District,Yantai City.Methods 438 diabetes patients who received free diabetic retinopathy (DR) screening in Traditional Chinese Medicine Hospital of Muping District of Yantai City from April 2012 to June 2013 were enrolled in the cross-sectional study.The re-examination rate at five years later,as well as the possible associated factors,including age,gender,height,weight,education level,occupation,past medical history,smoking and drinking habits,diabetes process,diabetes medication history,severity of DR,glycosylated hemoglobin (HbA1 c),renal functionand blood lipid were analyzed and evaluated.Results Among 438 patients,159 returned for check up five years later,with a follow-up rate of 36.3％.Further analysis revealed that follow-up rate was related to occupation types (P =0.003) and HbAlc level (P =0.006).Other factors did not show statistical significance (P ＞ 0.05).Conclusions The compliance of DR screening visits is related to occupational type and blood glucose control.It is suggested that in the screening of DR in China,we should pay attention to the propaganda and education of diabetic patients to control blood glucose,and focus on some occupational diabetes people,such as housework workers and farmers.

Objective To evaluation the comprehensive acquired immunodeficiency syndrome (AIDS) intervention program conducting in men who have sex with men (MSM) population living in Inner Mongolia Autonomous region. Methods A comprehensive intervention program was carried out among MSM groups in Hohhot and Baotou City. Seven hundred and six and 767 MSM were enrolled for investigation through the snowball method during May 2008 and May to June 2009, respectively.At the same time, 5 mL intravenous blood sample was collected from each subject for human immunodeficiency virus (HIV) detection and intervention effect evaluation. Data were analyzed by x2test. Results After intervention, the awareness rate of HIV/AIDS knowledge increased from 70.7%(499/706) to 81.7%(627/767) (x2 =25. 004, P＜0.01 ). The rate of consistent condom use in the last six months increased from 38.0%(254/668) to 45.3% (346/764) (x2=8. 269, P＜0. 05). The percentage of subjects who had more than 5 different male sexual partner during the last 6 months significantly decreased from 42.8% to 24.6% (x2 = 55. 348, P＜0.01). The median number of sexual partners in MSM decreased from 3 in 2008 to 2 in 2009. The HIV infection rate was 1.7 % in both 2008 and 2009. Conclusion The comprehensive intervention program among MSM population shows positive influence after one year implementation, which is helpful for increasing HIV/AIDS awareness and safe sex behavior in this population.
