Objective To observe the clinical effect of treatment of type 2 diabetes with Glargine and Novolin 30R.Methods68 patients from June 2015 to October 2016,were randomly divided into insulin glargine group and Novolin 30R each group 34 cases, According to the medical staff were given psychological counseling for patients to explain the importance of disease related knowledge and related treatment, timely eliminate/alleviate the negative emotion of patients with, to ensure that patients with a good attitude to face treatment;Follow-up and It occurred in January when the two groups were recorded hypoglycemia ratio, triglyceride (TG), total cholesterol (TC), 2h postprandial blood glucose (2hPG), glycated hemoglobin, the use of statistical methods for data analysis.ResultsThe proportion of patients with insulin glargine group hypoglycemia after treatment 2.94%, better than Novolin group 17.65%, and the difference was significant (P<0.05).②After treatment glargine group TG, TC index were (1.70±0.21) mmol/L, (5.24±0.16) mmol/L, were better than Novolin group (3.04±0.35) mmol/L,(5.58±0.22) mmol/L, and the differences were statistically significant (P<0.05).After treatment glargine group glycated hemoglobin was (7.02±0.18)%, lower than Novolin group (7.78±0.30)%, and the differences were statistically significant (P<0.05).ConclusionGlargine and Novolin 30R can effectively control blood sugar, low insulin glargine hypoglycemia event rate, the better the treatment of type 2 diabetes, is worthy of further research and application.

Objective: To investigate the causal relationship between antioxidant nutrients and pregnancy complications, so as to provide the reference for the prevention and treatment of pregnancy complications. Methods: Data of seven antioxidant nutrients including vitamin A, vitamin C, vitamin E, selenium, zinc, copper and iron were collected from genome-wide association study (GWAS) Catalog database, and data of four pregnancy complications including gestational diabetes mellitus, pre-eclampsia, spontaneous abortion and preterm birth were collected from the Finland database. Single nucleotide polymorphism (SNP) data were collected, and 27 SNPS strongly correlated with seven antioxidant nutrients were selected as instrumental variables. Mendelian randomization (MR) analyses were performed using the inverse-variance weighted (IVW) method with seven antioxidant nutrients as exposures factors and four pregnancy complications as outcome variables. The heterogeneity was assessed using the Cochran's Q test, the horizontal pleiotropy was assessed using the MR-PRESSO test and MR-Egger regression, and the robustness of the results was verified with the leave-one-out. Results: Cochran's Q test showed heterogeneity of MR results between vitamin C and gestational diabetes mellitus, preeclampsia and preterm birth, between vitamin E and iron and gestational diabetes (all P<0.05), and a random effect model was employed. There was no heterogeneity in other results (all P>0.05), and a fixed effect model was employed. MR analysis results showed that there was no causal association between seven antioxidant nutrients and the risk of four pregnancy complications (all P>0.05). MR-PRESSO test and the MR-Egger regression identified no horizontal pleiotropy of instrumental variables (both P>0.05). Conclusion This study did not find genetically predicted associations of antioxidant nutrients with pregnancy complications.

Objective:To investigate the effects of TNF-α knockout on liver and spleen neutrophil responses to Vibrio vulnificus bloodstream infection in a mouse model. Methods:(1) TNF-α-knockout (TNF-α -/-) and wild-type (WT) C57BL/6J mice aged 6-8 weeks were randomly divided into four groups with six in each group: uninfected WT group, infected WT group, uninfected TNF-α -/- group and infected TNF-α -/- group. The mouse model of bloodstream infection was constructed by intraperitoneal injection of Vibrio vulnificus CGMCC1.1758 (2×10 8 CFU/200 μl), while the mice in the uninfected groups were injected intraperitoneally with equal amount of PBS. (2) Liver immune cells and splenocytes were isolated 4 h after infection and subjected to analyze the percentages and numbers of neutrophils, and the changes in cell viability, cellular reactive oxygen species (ROS) level and phagocytosis by flow cytometry. In addition, effects of Vibrio vulnificus bloodstream infection on mTOR signaling pathway in murine neutrophils were evaluated in vivo. Results:(1)Compared with the uninfected WT group, the percentages and numbers of neutrophils in liver and spleen tissues of the infected WT group increased significantly. The percentage and number of liver neutrophils were significantly higher in the infected TNF-α -/- group than in the infected WT group, but no significant difference in spleen neutrophils was detected between the two groups. (2) Compared with the infected WT group, the phagocytosis of liver neutrophils rather than that of spleen neutrophils was enhanced in the infected TNF-α -/- group. (3) The survival rates of neutrophils in both liver and spleen were decreased, while the cellular ROS level was significantly increased in the infected WT group compared with those of the uninfected WT group. Compared with the infected WT group, the infected TNF-α -/- group had increased survival rates of both liver and spleen neutrophils, but decreased level of ROS. (4) The levels of p-AKT (S473) in liver and spleen neutrophils of the infected WT group were lower than those of the uninfected WT group. Compared with the infected WT group, the infected TNF-α -/- group had lower level of p-AKT (S473) in liver neutrophils, but higher p-AKT (S473) level in spleen neutrophils. There were no significant differences in p-4E-BP1(T37/46) levels between the uninfected WT group and the infected WT group. The p-4E-BP1 (T37/46) level in liver neutrophils was lower in the infected TNF-α -/- group than in the infected WT group, but no significant difference in p-4E-BP1 (T37/46) levels in spleen neutrophils was observed between the two groups. Conclusions:TNF-α had different effects on the neutrophils in spleen and liver tissues of mice with Vibrio vulnificus bloodstream infection. It played a critical role in regulating the recruitment, phagocytic function and mTOR signaling of liver neutrophils after Vibrio vulnificus infection in vivo.
