Objective To investigate the influence of insulin pump on type 2 diabetes mellitus.Methods 51 patients were randomized into two groups: 31 cases controlled with insulin pump,20 treated with oral antidiabetic drugs.Serum level of C-peptide concentration was observed.Results There was a markedly increase in C-peptide level in both insulin treating group(P<0.001) and oral drug group(P<0.01).Half an year later,the insulin group was improved in β-cell function better than oral drug group.Conclusions Several days controlling of severe hyperglycemia with insulin pump could not eliminate the β-cell inhibition of glucose toxicity.Newly diagnosed severe type 2 diabetes(FPG≥14 mmol/L) could be treated with insulin for several months.

Objective To investigate the incidence of iron overload (liver biopsy tissue Prussian blue staining was positive)in newly diagnosed type 2 diabetic patients (T2DM) and to analyze the SLC40A1 gene (NG_009027.1) mutation in 12 newly diagnosed T2DM with iron overload.Methods 198 patients with newly diagnosed T2DM were collected in our hospital from December 2014 to December 2015.12 of them had elevated ferritin and liver biopsy tissue Prussian blue staining was positive.DNA was extracted from the paraffin section of liver tissue and the exons of SLC40A1 gene were amplified by polymerase chain reaction (PCR).The purified products were sequenced in two directions.Results The incidence of iron overload in these newly diagnosed T2DM patients was about 6%.One point mutation c.663T> C was found on the sixth exon region of SLC40A1 gene in all these 12 T2DM patients with iron overload.It's encoded amino acid did not change (221V>V),meaning a samesense mutation.Conclusion Iron overload has a certain incidence in patients with newly diagnosed T2DM.Iron overload may not due to the mutations in SLC40A1 gene,which need further investigation.

Objective To investigate the effect of berberine on glucose absorption and mRNA expression of 11 β-hydroxysteroid dehydrogenase type 1 ( 11β-HSD1 ) in insulin-resistant HepG2 cell model.Methods HepG2 cells were incubated with high-concentration insulin for 24 hours to build insulin-resistant cell model.In order to evaluate the cells for insulin resistance,the cells were cultured with different concentrations of insulin for 24 hours.The insulin-resistant cells were treated with different concentrations of berberine and insulin for 24 hours and the non insulin-resistant cells were used as a control.The glucose concentration in culture medium was detected by the method of glucose oxidase-peroxidase (GOD-POD).According to the glucose concentrations in blank medium and those in the medium of culturing cells 24 hours later,the rate of absorpting glucose by the cells was calculated.The mRNA expression of 11β-HSD1 in the insulin-resistant cells was detected by the reverse transcription polymerase chain reaction (RT-PCR).Results Incubated with 10-7mol/L insulin for 24 h,the insulin-resistant cell model had been built.The rate of glucose absorption of the model cell treated with high concentration berberine ( 10 μmol/L) was significantly improved [(42.53 ±1.99)％ vs (28.16±1.99)％,t =12.9457,P ＜0.01].High-concentration berberine showed a strong synergy with insulin on glucose absorption of the model cells.As the cells became resistant to insulin,the mRNA expression of 11β-HSD1 increased significantly compared to non insulin-resistant cells( relative expression quantity was (4.60 ±0.96 vs 0.67 ±0.42,t =4.9476,P ＜0.05 ).While the mRNA expression of 11β-HSD1 reduced in the insulin-resistant cells after treated with high-concentration berberine,and the relative expression quantity was not significantly different with non insulin-resistant cells ( 1.12 ±0.35 vs 0.67 ±0.42,P ＞0.05).However,low-concentration ( 1 μmol/L) of berberine had not the same role.Conclusions It is concluded that one of the acting mechanism of berberine improving the insulin sensitivity may be that the mRNA expression of 11β-HSD1 is downregulated in the insulin-resist-ant liver cell model depending on concentration.

The occurrence and development of type 2 diabetes mellitus(T2DM) are related to abnormal energy metabolism.L-carnitine,as one of the most important drugs to improve energy metabolism,has gradually been in a hot research in recent years.It can prevent cell lipid peroxidation,prevent oxidation by free radical scavenging,promote long-chain fatty acids into mitochondria for β-oxidation and increase lipid metabolism and improving diabetic complications.It can also decrease insulin resistance (IR),and lower fasting blood glucose (FBG).L-carnitine may have certain inhibitory effect on the development of T2DM.Early application of L-carnitine may improve the complication of T2DM diabetes,and provide a new way for the treatment of T2DM.

BACKGROUND: Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps. METHODS: A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis. RESULTS: During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed. CONCLUSIONS ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.
