Objective To investigate the prevalence and associated risk factors of type 2 diabetes mellitus in populations of Uigurs and Kazaks in Xinjiang.Methods Four-stage selected random samples aged 35 years and over were used to analyze the prevalence and associated risk factors of type 2 diabetes mellitus in populations of Uigurs and Kazaks from 6 localities(Urumqi,Kelamayi,Fukang,the Turfan Basin locality,Hetian locality,Yili Hazakh autonomous prefecture)in Xinjiang according to different nationality,age,and sex.The data were collected according to questionnaire,and physical examination and laboratory test were performed.Results A total of 8 539 Uigurs and Kazaks adults were surveyed.The prevalences of type 2 diabetes mellitus were 5.01%and 3.16%in Uigurs and Kazaks.The prevalence in male was higher than that in female(5.22%vs3.89%,P<0.01).The prevalences of type 2 diabetes mellitus were2.45%,4.92%,5.94%,7.49%,and 5.64%in 35-44,45-54,55-64,65-74,>75 yeats of age groups,respectively.Age,gender,nationality,systolic blood pressure,body weight,triglyceride,and total cholesterol were the risk factors for type2 diabetes mellitus,with the ORs being0.742,1.025,0.673,1.050,1.005,1.517,1.126,respectively.Conclusion It is important to culture healthy life style,enhance the control of hypertension and hyperlipidemia in Uigurs and Kazaks patients for preventing type 2 diabetes mellitus in Xinjiang.

Objective To study the correlation between renal function and arterial stiffness of Uighur population over 35 years old in Xinjiang area. Methods From October 2007 to March 2010, four-stage stratified random sampling method was applied to collect a total of 4312 Uighur people over 35 years old in Urumqi, Karamay, Fukang, Turpan area, Hotan prefecture, Yili Kazak autonomous prefecture and Altai prefecture. The data of these 4312 general urban and rural Uygur residents were complete. Simplified MDRD formula was used to calculate the estimate glomerular filtration rate (eGFR). Arm-ankle pulse wave velocity (b-aPWV) of both sides was measured and the average value was used in correlation analysis with eCFR, and then the associated risk factors were adjusted. Results The eGFR was negatively correlated with b-aPWV (r=-0.174, P<0.01). Multiple linear regression showed that after adjusting some risk factors such as age, sex, body mass index, systolic blood pressure, diastolic blood pressure, waist circumference, hip circumference, uric acid, fasting blood glucose, total cholesterol, triglycerides, low density lipoprotein, eGFR was still negatively correlated with b-aPWV (P=0.012). Conclusions In Uygur population over 35 years old in Xinjiang, the glomerular filtration rate is negatively correlated with arterial stiffness.

Objective: To have a profound understanding of anti-N-methyl-D-aspartic receptor (anti-NMDAR) encephalitis, through the clinical analysis of 5 cases of anti-NMDAR encephalitis, and literature review. Methods: This is a retrospective analysis. Five cases of anti-NMDA receptor encephalitis treated from May 2010 to June 2015, in the Department of Neurology, Beijing Friendship Hospital affiliated to Capital Medical University, were included in this study. The clinical data, including clinical manifestation, past history, radiological features, serum and cerebral spinal fluid examinations, treatment and prognosis, were analyzed. Results: Among the 5 cases, 3 young female and 2 middle-to old-aged male. The clinical features of the onset was mental and behavior disorder, as well as seizure and extrapyramidal features, like facial and limbic involuntary movements or tremor. Coma and hypopnea was severe in 3 young female cases, needing assistance of mechanical ventilator, while the manifestation of 2 male patients was much mild, need not assisted respiration. 1 case had teratoma of ovary, 1 case had Vogt-Koyanagi-Harada syndrome. The anti-NMDA receptor antibody was positive in cerebraospinal fluid of all 5 cases, but in serum of 3 cases, serum and CSF Epstein-Barr virus (EBV) IgM antibody was positive in 1 case, while herpes simplex I virus (HSV-1) IgM antibody positive in another case, and anti-myelin oligodendrocyte glycoprotein (MOG) antibody was seen in serum and CSF in 1 case. The time interval from the onset to treatment was 10-37 d (18.8±9.8 d). IVIG was used in all of the 5 cases, glucocoticoid in 4 cases, and plasma exchange in 3 cases. One case with Vogt-Koyanagi-Harada syndrome, having a long time before diagnosis and treatment, died, while the other 4 cases had good prognosis, and had no relapse. Conclusions Mental and behavior disturbance is common at onset of anti-NMDAR encephalitis. The radiological and lab examination may be normal. It may be accompanied with HSV-1 or EBV infection, anti-MOG antibody may be positive in this disease. Active treatment is important.

Objective: To investigate the role of lectin-like Ox-LDL receptor-1( LOX-1) in the activation and oxidative stress of cultured human umbilical vein endothelial cell(HUVEC) after human cytomegalovirus(HCMV) infection. Methods: HUVEC were divided into four groups: HCMV, Control, Carrageenan, and HCMV+ Carrageenan. After HCMV AD169 infection, the supernatant of the culture was extracted, and cells were lysed. The levels of LOX-1 mRNA, intercellular adhesion molecule-1(ICAM-1) mRNA and vascular cellular adhesion molecule-1(VCAM-1) in HUVEC were measured by real-time PCR. And the content of nitrogen monoxidum(NO) of the supernatant was detected by nitrate reductase method accordingly. Results: 24 h after infection, the mRNA expression of LOX-1, ICAM-1 and VCAM-1 in HUVEC of HCMV infected group increased obviously compared to control, and NO quantity increased accordingly. The mRNA expression of LOX-1, ICAM-1 and VCAM-1 and the quantity of NO decreased after adding the LOX-1 inhibitor carrageenan. There was significant difference between groups(P<0.05). Conclusions HCMV may increase the mRNA expression of ICAM-1 and VCAM-1 and quantity of NO by upregulating the mRNA expresion of LOX-1, which may contribute to the formation of a therosclerosis(AS).
