RESUMO
Metabolic syndrome is a clustering of metabolic disorder with unclear molecular mechanism. Increasing studies have found that the pathogenesis and progression of metabolic syndrome are closely related to inflammation. Here, we report celastrol, a traditional Chinese medicine, can improve high fat diet-induced metabolic syndrome through suppressing resistin-induced inflammation. Mechanistically, celastrol binds to adenylyl cyclase associated protein 1 (CAP1) and inhibits the interaction between CAP1 and resistin, which restrains the cyclic adenylate monophosphate (cAMP)-protein kinase A (PKA)-nuclear factor kappa-B (NF-
RESUMO
Tyrosine phosphatase SHP2 is a promising drug target in cancer immunotherapy due to its bidirectional role in both tumor growth promotion and T-cell inactivation. Its allosteric inhibitor SHP099 is known to inhibit cancer cell growth both and . However, whether SHP099-mediated SHP2 inhibition retards tumor growth anti-tumor immunity remains elusive. To address this, a CT-26 colon cancer xenograft model was established in mice since this cell line is insensitive to SHP099. Consequently, SHP099 minimally affected CT-26 tumor growth in immuno-deficient nude mice, but significantly decreased the tumor burden in CT-26 tumor-bearing mice with intact immune system. SHP099 augmented anti-tumor immunity, as shown by the elevated proportion of CD8IFN- T cells and the upregulation of cytotoxic T-cell related genes including , which decreased the tumor load. In addition, tumor growth in mice with SHP2-deficient T-cells was markedly slowed down because of enhanced anti-tumor responses. Finally, the combination of SHP099 and anti-PD-1 antibody showed a higher therapeutic efficacy than either monotherapy in controlling tumor growth in two colon cancer xenograft models, indicating that these agents complement each other. Our study suggests that SHP2 inhibitor SHP099 is a promising candidate drug for cancer immunotherapy.
RESUMO
Objective To apply the Plan -Do -Check -Act ( PDCA ) cycle in glucose management in inpatients with diabetes , in order to decrease the incidence of hypoglycemia and related complications .Methods 517 inpatients with diabetes were divided into 4 groups according to the quarter ,the monthly incidence rates of hypo-glycemia were collected.The association of monthly incidence of hypoglycemia with age (≥65 years),longer diabetic history (≥5 years),lower C-peptide (<0.370nmol/L),receiving combined regimen (basal insulin plus 3 doses of pre-prandial short-acting insulin ) were analyzed .PDCA cycle was applied for hypoglycemia detection and etiolo-gy control in order to achieve quality improvement via effective glucose control measures .Theχ2 test was used to ana-lyze the incidence of the hypoglycemia in each group .The hypoglycemic incidence based on different characteristics , were also compared with the overall hypoglycemic incidences of all patients .Results The incidence of hypoglycemia was significantly reduced with the application of PDCA cycle in inpatients with diabetes ,from 44.09% in the first quarter to 13.04% in the fourth quarter (χ2 =32.815,P<0.001).The annual hypoglycemic incidence rate was 26.89%.The patients with low C-peptide or receiving combined regimen had significantly higher incidence rate of hypoglycemia (53.57%and 31.88%) as compared to general inpatients with diabetes (χ2 =35.721,7.105,all P<0.05).Conclusion The application of PDCA cycle can effectively decrease the incidence of hypoglycemia ,and it can be a great asset for management of inpatients with diabetes .
RESUMO
Objective To study the application of walking combined with Buerger exercise in the treatment of grade 0 diabetic foot.Methods Eighty patients with grade 0 diabetic foot were randomly divided into observation group and control group.The control group was trained by walking exercise .The observation group was trained by walking combined with Buerger exercise through 12 months of training.The changes of self-sensory symptoms,ABI and DAWV were observed.Results The self-sensory symptoms of the two groups were significantly decreased (observation group: markedly effective 15 cases,effective 19 cases;control group: markedly effective 5 cases,effective 23 cases).The effective rate of the observation group was higher than that of the control group (85% vs.70%,χ2 =7.831,P <0.05).The ABI ratio of the two groups were higher than those before treatment ,and the ABI ratio of the observation group was higher than that of the control group [(0.889 ±0.113) vs.(0.842 ±0.124),t =1.772 P <0.05].The ratio of DAWV in the observation group was higher than that in the control group [(6.772 ±0.435)cm/s vs.(6.543 ±0.552)cm/s,t =2.061,P <0.05].Conclusion Walking combined with Buerger exercise can improve the blood flow velocity and blood flow of the collateral circulation of the lower limbs of patients with grade 0 diabetic foot,and improve the self-sensory symptoms of peripheral neuropathy .

RESUMO
Objective To explore the influence of peer support on blood glucose management of type 2 diabetic patients.Methods From April 2017 to December 2017,the study subjects were selected according to the inclusion criteria from all type 2 diabetes patients who admitted in the Fourth People′s Hosipital of Ningbo.The patients in bed 1-9 were assigned into observation group,and patients in bed 10-20 were assigned into control group.All beds were assigned randomly from a random number generator.Standard diabetes education was provided to both two groups,while peer support was added to the experimental group.The average hospitalization costs and length of hospital stay were compared between the two groups using t-test.Results The average hospitalization cost of the observation group was(6218.48 ±1432.75)yuan,which of the control group was(6913.32 ±1426.34)yuan,the average hospitalization time of the observation group was(6.49 ±1.91)d,which of the control group was(7.41 ±1.99)d,the differences between the two groups were significant(t=-4.480,-4.347,all P<0.01).Conclusion Application of peer support to the glucose management in patients with type 2 diabetes can effectively enhance education effect and reduce hospitalization cost and length of hospital stay.
RESUMO
Objective To explore the relationship between homocysteine (Hcy)expression and diabetic nephropathy in patients with type 2 diabetes mellitus (T2DM).Methods 100 cases with T2DM were selected,they were divided into observation group(diabetic early nephropathy,n =50)and matched group(simple diabetes,n =50),50 healthy people were involved as control group.Hcy,BUN and Cre were detected and compared among groups. Results Hcy level in 3 groups showed a increased trend,there were significant differences among groups (F =145.007,P 0.05),the comparison between groups also had no statistical significance (P =0.936,0.097,all P >0.05 ). Conclusion Hcy may participate in the process of early type 2 diabetic nephropathy,can be used as important reference index of diagnosis of early diabetic nephropathy.
