RESUMO
Objective To investigate the relationship between adiponectin /leptin ratio and metabolic index in type 2 diabetes mellitus .Methods A total of 167 cases of type 2 diabetes in our hospital endocrinology clinic 59 people from January 2013 to 2014 were enrolled in the study ,all patients were divided into three groups accordius to fasting plasma glucose(FPG)(42 people 9 .4mmol/L as Group 3) .Patients who have been excluded from treatment with insulin or insulin .Requiring patients to 10 - 12 hours of fasting ,taken fasting blood samples and samples will be sent to the hospital clinical laboratory measured by biochemical analysis way ,the patient of glycosylated hemoglobin ,fasting blood glucose ,blood lipid indexes for comprehensive testing and calculation of patient related indexes ,and carries on the analysis .Results the patient′s body mass index(BMI) ,fasting insulin (FINS) ,low‐density lipoprotein cholesterol(LDL) ,triglyceride(TG) ,leptin and adiponectin ,between the ages of no statistical significance exists ,male patients with adiponectin levels and TG ,BMI ,HDL and LDL has a relatively close relationship (positive ,P=0 .000 3) leptin levels and BMI was negatively correlated (P<0 .05) .The adi‐ponectin levels of female patients were closely related to TG ,LDL and HD (positive correlation ,P<0 .05) .Leptin levels and TG were associated with BMI (negative correlation) ,and A/L ratio was correlated with all the indexes (negative correlation) in male and female patients (P<0 .05) .Conclusion HOMA‐IR can not be used as an important indicator of insulin resistance ..A/L and it are more suitable for .
RESUMO
Objective To investigate the effects of carboxymethytl pachymaram ( CMP ) on the methylation of SOCS-1 (suppressor of cytokine signaling-1) gene and the in vitro maturation of human mono-cyte-derived dendritic cells (DCs).Methods Human DCs were induced from the peripheral blood mono-cytes in vitro with the treatment of recombined human GM-CSF and interleukin-4 ( IL-4 ) and cultured with different concentrations of CMP (10, 50, and 100 mg/L).The methylation and expression of SOCS-1 gene were analyzed by methylation-specific polymerase chain reaction (MSP) and real-time PCR, respectively. The phenotypic markers of DCs were detected by flow cytometry .Mixed lymphocyte reaction ( MLR) and ELISA were performed to measure the lymphocyte proliferation induced by DCs and IL-12 secretion by DCs . Results CMP promoted the methylation of SOCS-1 gene, but inhibited the expression of SOCS-1 gene in dendritic cells at the concentrations of 50 mg/L and 100 mg/L.The expression of phenotypic markers (CD80, CD83, CD86 and HLA-DR), IL-12 secretion and lymphocyte proliferation induced by DCs were significantly enhanced in a dose dependent manner with the treatment of CMP .Compared with control group , the levels of methylated SOCS-1 gene and IL-12 and the lymphocyte proliferation index were increased upon the stimulation with 50 mg/L and 100 mg/L of CMP (P<0.01), but the expression of SOCS-1 gene was de-creased.The expression of CD80, CD83 and HLA-DR on DCs in the presence of 100 mg/L of CMP were higher than those of control group (P<0.05).Conclusion CMP could induce the methylation of SOCS-1 gene and the maturation of DCs derived from peripheral blood monocytes .
RESUMO
Objective To produce anti-thrombomodulin antibodies.Methods Using genetic immunization: Eukaryotic expression plasmid pcDNA3.1/TM(LEO),encoding all the extracellular domain of human thrombomodulin and signal peptides but lacking the transmembrance and cytoplasmic domains was constructed, which recombinant thrombomodulin was secreted soluble product. The plasmid was isolated from large-scale bacterial cultures by treatment with alkali and SDS, purified by precipitation with polyethylene Glycol (PEG). Recombinant plasmid was injected into tibial muscle of BALB/c mice. The productions of TM and anti-TM have been detected. Results The positive of RT-PCR and expressed TM identified the function of the recombinant plasmid. The pcDNA3.1/TM(LEO) induced higher titer of anti-TM. The antibody titer peaked between the 5th and 7th injection with a titer of 1∶8 000 detected by cell-ELISA coated with EVC-304. Specificity has been identified by western blot and immunohistochemistry.Conclusion The production of antibody through genetic immunization was a feasible method due to the difficulties in obtaining and purification of natural thrombomodulin.
