[Analysis on epidemiological characteristics and related factors of dyslipidemia among adult residents of Xinjiang Uygur Autonomous Region during 2013-2014].

Objective: To study the epidemiological characteristics and related factors of dyslipidemia among adult residents in Xinjiang Uygur Autonomous Region (Xinjiang) in 2013-2014. Methods: A total of 4 120 adult residents consisting of Han and Uygur group aged over 18 years old were selected by using a stratified cluster random sampling method in 8 counties of Xinjiang from 2013 to 2014. The related factors of dyslipidemia were collected by questionnaire and physical measurement. The total cholesterol, triglyceride, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were detected by enzyme method. Factors associated with dyslipidemia were analyzed by chi-squared test and a multivariate unconditioned logistic regression model adjusted for gender, urban or rural area, age-group, body mass index (BMI), central obesity, smoking, drinking, education attainment, diabetes mellitus and hypertension. Results: The prevalence of dyslipidemia was 45.00% (1 854 cases). The prevalence of dyslipidemia was higher in Uygur group (47.80% (977/2 044)) than that in Han group (42.24% (877/2 076)) (χ(2)=12.84, P<0.001). The analysis showed that dyslipidemia was related with gender (OR=0.41, 95%CI: 0.33-0.51), urban area (OR=0.54, 95%CI: 0.39-0.76), BMI (overweight group (OR=1.52, 95%CI: 1.18-1.96); obesity group (OR=2.20, 95%CI: 1.64-2.96)), central obesity (OR=1.66, 95%CI: 1.29-2.14) and diabetes mellitus (OR=1.49, 95%CI: 1.06-2.11) in Uygur group. The analysis also showed that dyslipidemia was related with BMI (overweight group (OR=1.72, 95%CI: 1.32-2.25), obesity group (OR=2.60, 95%CI: 1.85-3.64)), central obesity (OR=1.45, 95%CI: 1.13-1.87), smoking (OR=1.46, 95%CI: 1.09-1.95), diabetes mellitus (OR=1.77, 95%CI: 1.38-2.25) and hypertension (OR=1.62, 95%CI: 1.31-2.00) in Han group. Conclusions: The prevalence of dyslipidemia in Xinjiang was higher than the national average prevalence. The prevalence of dyslipidemia in Uygur group was significantly higher than that in Han group. The gender, living area, BMI, central obesity and diabetes mellitus were risk factors of dyslipidemia in Uygur group, and BMI, central obesity, smoking, diabetes mellitus and hypertension were risk factors of dyslipidemia in Han group in Xinjiang.

[Prevalence of central obesity among floating population employment in 5 surveillance sites of Xinjiang Uygur Autonomous Region in 2012].

OBJECTIVE: To investigate the prevalence of central obesity among different gender and age groups of floating population employment in 5 surveillance sites of Xinjiang Uygur Autonomous Region. METHODS: 1491 floating population aged > 18 years old were selected through multistage clustering sampling method, stratified by 6 major industries in5 sites of Xinjiang Uygur Autonomous Region( Xinhe County, Yining County, Tianshan District, Hetian County and Kashi City) in 2012. Unified questionnaire( including basic information, behavioral risk factors, etc. ), designed by China CDC, were used to collect information by face-to-face interviews. Height, weight and waist circumference were measured by unified equipment. RESULTS: The average age was( 35. 73 ± 11. 61) years old. Male and female accounted for 48. 02%( 716/1491) and 51. 98%( 775/1491)each. Han, Uygur and other ethnic group accounted for 75. 59%( 1127/1491), 18. 31%( 273/1491) and 6. 10%( 91/1491). The prevalence of central obesity was 25. 62%( 382/1491) of floating population in 5 surveillance sites of Xinjiang Uygur Autonomous Region, 50-59 years age group( 45. 63%) and the obese group( 86. 15%) in BMI were the highest prevalence of central obesity. There was statistical significance on prevalence of central obesity in different age groups floating population( χ~2= 77. 295, P <0. 001), and in different BMI groups floating population( χ~2= 648. 619, P < 0. 001). CONCLUSION: Floating population aged 50-59 years old and obese in BMI of Xinjiang Uygur Autonomous Region were key groups for prevention and control of central obesity.

An Investigation of the First Case of Human Rabies Caused by a Fox in China in May 2016 / 生物医学与环境科学（英文）

This study assesses the causes and prevention measures of rabies through epidemiological investigation and analysis. A field epidemiological survey was conducted to investigate a case of rabies by fox bite. The onset of symptoms began 50 days after the bite. The patient did not receive standard treatment, rabies vaccination, or rabies immunoglobulin injection. The fox was killed on the spot. Saliva and pre-death blood samples were collected at different periods, and only blood RT-PCR tests yielded positive results. Wild fox bite is a major risk factor of rabies infection in Xinjiang Province, China.

[Study on realgar nanoparticles inhibition of adenovirus replication at the gene level].

OBJECTIVE: Modeling HAdV-3 infect Hep-2 cells in vitro. The effect of realgar nanoparticles on the expression of HAdV-3 is detected by using fluorescent quantitative PCR. METHODS: The experiment is divided into four groups: Hep-2 cells control group, HAdV-3 virus control group, realgar nanoparticle group and ribavirin group. In order to detect HAdV-3 viral load, add realgar nanoparticles and ribavirin in vitro and remain that vitro for 24 hours when HAdV-3 has infected Hep-2 cells, extract total DNA of Hep-2 cells infected by HAdV-3, and establish Real-time PCR reaction system of every experimental groups. RESULT: The Hep-2 cells group has no amplification curve, the Ct value is greater than 35, which illustrate HAdV-3 pathogen detection is negative. However, realgar nanoparticles group, ribavirin group and the HAdV-3 group have amplification curve, the Ct values are 29.30 +/- 0.08, 33.05 +/- 1.29, 26.01 +/- 0.25 respectively, which illustrate HAdV-3 pathogen detection is positive. The viral copy amount of the adenovirus group(66 699 932 +/- 23.85) is more than that of realgar nanoparticles group (912 435.44 +/- 16.57), and much greater than that of ribavirin group (459 124.84 +/- 12.82) (P < 0.05). CONCLUSION: The model of Hep-2 cell infected by HAdV-3 is reliable. The method of quantitative PCR is sensitive and specific. Realgar nanoparticles have a certain inhibition role for adenovirus nucleic acid replication.
