Objective To investigate the effects of long-term high-fat diet and the modern lifestyle of more food and lack of exercise on insulin resistance and islet function. Methods 75 Wistar rats were feed by routine or high-fat diet for 11 months. Some of high-fat rats were induced to diabetic models by injecting 12mg/kg streptozotocin. Islet function was evaluated by intraperitoneal glucose tolerance test. Insulin sensitivity was detected by insulin tolerance test. Results Compared with control group, 2h blood glucose of high-fat group was elevated significantly. Fasting blood glucose of high-fat group was also elevated at eleventh month. Body weight of high-fat group was increased remarkably compared with control group, and the insulin sensitivity of high-fat group was decreased by 50% at forth month. Then insulin sensitivity of both groups was declined greatly. Hypoglycemic effect of 0.5 U/kg insulin at ninth month was similar to that of 0.1U/kg insulin at forth month. Furthermore, no significant difference of insulin sensitivity was observed between high-fat group and control. Conclusions Main course for insulin resistance is the modern lifestyle of more food and lack of exercise. The main effect of high-fat diet on the occurrence of diabetes is damaging islet function.

G protein coupled receptors (GPCRs) have a marked mediating effect on bodily immunoregulation. Recent years’ studies found that GPCRs plays an important role in the mechanism of the intervening effect of electroacupuncture on rheumatoid arthritis pain. Of them, adrenergic receptors, 5-hydroxytryptamine receptors, adenosine receptors, opioid peptide receptors, dopamine receptors and cannabinoid receptors separately mediate the effect of electroacupuncture on rheumatoid arthritis pain in the central and peripheral nervous systems and the inflammatory region. The exploration of the mechanism by which electroacupuncture increases GPCRs expression is our future research direction.

Objective To investigate the effect of α-keto acid combined with low protein diet on kidney function, calcium-phosphorus metabolism and adenosine deaminase activity in malnourished patients with long term peritoneal dialysis.Methods Forty-six cases malnourished patients with long term peritoneal dialysis were selected from May 2013 to August 2014 in the hospital and divided into two groups.The control group (n=23) were treated by conventional therapy, acceptable daily intake of protein 1.2 g/(kg? d).The experiment group (n=23) were treated by α-keto acid combined with low protein diet, acceptable daily intake of protein 0.8 g/(kg? d).Two groups were treated for three months.Serum calcium, phosphorus, nutritional status assessment, adenosine deaminase activity and renal function were observed and compared after treatment.ResuIts After twelve months ’ treatment, compared with control group, serum creatinine, blood urea nitrogen, serum uric acid of experiment group were lower ( P<0.05); serum calcium level was higher (P<0.05), serum phosphorus level was lower (P<0.05);ADA activity and white blood cell count were lower (P<0.05). The incidence of malnutrition rate had no significant difference between two groups(χ2 =3.136,P>0.05).ConcIusion α-keto acid combined with low protein diet could effectively increase serum calcium level, reduce serum phosphorus level, ADA activity and WBC count, and improve nutritional status in long-term peritoneal dialysis patients, which has important significance.

Objective MicroRNAs (miRNAs) are of important clinical value in various tumors.However, few studies are reported about their role in thymic epithelial tumors.This article aims to explore differential expression profile of miRNAs in type B3 thymoma and thymic carcinoma.Methods This study included the pathological data about 45 cases of type B3 thymoma and thymic carcinoma surgically treated in our hospital from January 2012 to January 2015, of which 3 cases of type B3 thymoma (control group) and another 3 cases of thymic carcinoma (case group) were subjected to miRNA microarray for determination of the differential expressions of miRNAs in the tumor tissues.The up-and down-regulated miRNAs were calculated, their target genes were predicted via online databases, and the thymus-related genes were identified.Results Totally, 32 differentially expressed miRNAs (including miR-125b-1-3p, miR-3175, and miR-4462) were up-regulated and another 19 (including miR-361-5p, miR-130a-3p, and miR-3651) down-regulated in thymic carcinoma.AKT1, C9, CD19, CDC42, LSS, and MYC were identified as the target genes of miR-377-5p, ADCYAP1R1, ASPA, CAD, and CD63 as the target genes of miR-458-5p, and AKAP12, CD28, FOXP1, and MDM4 as the target genes of miR-183-5p.Conclusion Differentially expressed miRNAs were identified in type B3 thymoma and thymic carcinoma and their target genes predicted using the prediction software, which may provide some valid evidence for further study of thymic epithelial tumors.
