Effect of Xinjiang Uyghur Vernonia anthelmintica Willd Injection Treatment with Silicosis Fibrosis.

Objective. To observe the curative effect of VAWI on Xinjiang Uygur patients with silicosis fibrosis. Methods. After we diagnosed the 40 patients with the first phase of silicosis, we randomly divided them into two groups: the basic treatment group (group A, n = 20) and the VAWI group (group B, n = 20). At the same time, we selected the age-matched healthy patients (n = 20). We applied the combined protein chip with SELDI-TOF-MS to carry out the serum analysis. The data were analyzed throughout data preprocessing, difference in PEAK screening, hierarchical cluster analysis, and Principal Component Analysis (PCA). We built decision tree model and predict the difference between the PEAK corresponding proteins. Results. The proteins peaks corresponding to name, predicted protein, and gene name were as follows: M2001_69, amyloid beta a4 protein, APP, and M2017_02, amyloid beta a4 protein, APP. The different expression of proteins in patients with silicosis was found before and after with VAWI treatment. The predicted proteins were as follows: M1982_50, amyloid beta a4 protein, APP; M3164_50, fibrinogen alpha chain frag, FGA; M3379_28, fibrinogen alpha chain frag, FGA; and so on. Conclusion. VAWI presented curative effect on patients with silicosis fibrosis via the alternation of proteins expression in serum.

Association of rs7754840 G/C polymorphisms in CDKAL1 with type 2 diabetes: a meta-analysis of 70141 subjects.

The reported association of the CDKAL1 rs7754840 G/C gene polymorphism with T2DM susceptibility remains controversial. In this study, this association was further investigated using a meta-analysis of 33,149 patients and 36,992 controls from 32 independent studies. The random-effect models were used in order to evaluate the pooled odds ratios (ORs) and their 95% confidence intervals (CIs). A significant relationship between the CDKAL1 rs7754840 G/C gene polymorphism and T2DM was observed under allelic (OR: 1.37, 95% CI: 1.22, 1.55, P < 0.001), recessive (OR: 1.58, 95% CI: 1.20-2.08, P < 0.001), dominant (OR: 1.13, 95% CI: 1.21-1.33, P = 0.01), and homozygous (OR: 1.27, 95% CI: 1.21-1.33, P < 0.001), and heterozygous (OR: 0.83, 95% CI: 0.75-0.93, P < 0.001). Overall, the CDKAL1 rs7754840 G/C gene polymorphism was found to be significantly associated with an increased T2DM risk; the C allele of the CDKAL1 rs7754840 G/C gene polymorphism may confer susceptibility to T2DM.

Prevalence of metabolic syndrome, insulin resistance, impaired fasting blood glucose, and dyslipidemia in Uygur and Kazak populations.

This study was designed to evaluate the prevalence of the metabolic syndrome (MetS), impaired fasting blood glucose (IFG), insulin resistance (IR), hypertriglyceridemia (HTG), and low high-density lipoprotein cholesterol (HDL-C) in adult Uygur and Kazak populations. Questionnaires, blood pressure, anthropometric measurement, and fasting glucose were evaluated. The age-adjusted prevalence of MetS and IFG was 3.43- and 1.47-fold higher, respectively, in Uygurs compared with Kazaks. The prevalence of IR and HTG was 1.33- and 2.22-fold higher, respectively, in Uygurs compared with Kazaks. In addition, the prevalence of low HDL-C was 4.05-fold higher in Uygurs compared with Kazaks. These data depicted greater risk for cardiometabolic syndrome in Uygurs compared with Kazaks. In addition, all prevalence with the exception of low HDL-C was greater in men compared with women in both ethnic groups. For body mass index (BMI)<24, 24 to 28, and ≥28 kg/m2, the prevalence of MetS, HTG, and low HDL-C was higher in Uygurs than Kazaks at the same BMI level. For individuals with a BMI between 24 and 28, the prevalence of IR but not IFG was significantly greater in Uygurs than Kazaks. At BMI≥28, neither IFG nor IR was overtly different between the two ethnic groups.

The prevalence of type 2 diabetes and hypertension in Uygur and Kazak populations.

This study was designed to evaluate the epidemiology of type 2 diabetes and hypertension in Uygur and Kazak ethnic populations. A three-step stratified sampling method was used. Questionnaires, blood pressure, anthropometric measurement, and fasting blood glucose were monitored. In total, 1,571 Uygur and 2,913 Kazak subjects were randomly enrolled. The prevalence of type 2 diabetes and glucose intolerance was 5.55- and 1.90-fold higher, respectively, in Uygur than in the Kazak population (8.16 vs. 1.47%, P < 0.001 and 3.29 vs. 1.73%, P < 0.001). However, the prevalence of hypertension and obesity was significantly higher in the Kazak than in the Uygur population (hypertension: 43.52 vs. 31.98%, P < 0.001; obesity: 25.0 vs. 14.5%, P < 0.001, respectively). Our data suggest a significantly different prevalence in hypertension, hyperlipidemia, and type 2 diabetes between the two ethnic groups. The prevalence of type 2 diabetes was much lower, while the prevalence of hypertension was much higher associated with a higher incidence of obesity in the Kazak population. Individuals with a greater BMI and blood pressure were more prone to development of type 2 diabetes. Our data revealed that waist circumference of Kazak ethnics was greater than that of Uygur, even at the same BMI level. Serum fasting glucose was associated with different factors in Uygur and Kazak.
