Objective To study the effect of transient intensive insulin treatment on the serum free fatty acid (FFA) in newly diagnosed type 2 diabetic patients.Methods Sixty-four newly diagnosed type 2 diabetic patients were treated with transient intensive insulin.The fasting plasma glucose (FPG),2 hours post-prandial glucose (2hPG),lipid,fastin insulin (FINS),and serum FFA was examined hefore and after treatment.Results The levels of FPG,2hPG,total cholesterol (TC),triglycerides (TG),low density lipoproteins cholesterol (LDL-C),FFA and HOMA-IR after treatment were (9.68 ± 2.02) mmol/L,(12.77 ± 1.35) mmol/L,(4.26 ± 1.07) mmol/L,(1.52 ± 0.58) mmol/L,(2.50 ±0.75) mmol/L,(435.84 ± 190.94) μmol/L,0.51 ± 0.62,and they decreased obviously compared with those before treatment [(14.66 ± 3.50) mmol/L,(17.43 ±4.89) mmol/L,(5.03 ±0.94) mmol/L,(2.05 ± 1.42) mmol/L,(2.91 ±0.78) mmol/L,(586.68 ±229.45)μmol/L,0.65 ± 0.89](P＜0.05).The level of HOMA-β increased obviously (2.70 ± 0.83 vs.1.74 ± 1.04)(P＜0.05).The increase of HOMA-β and the decrease of HOMA-IR was positively correlated with the decrease of FFA.Conclusion The transient intensive insulin treatment can evidently decrease the level of FFA that can improve beta-cell function and relieve insulin resistance in newly diagnosed type 2 diabetic patients.

Objective To explore the correlation between NLR family pyrin domain containing 3 (NLRP3) and nonalcoholic fatty liver disease (NALFD).Methods A cross-sectional study was conducted in this study.Eighty four cases of health examination personnel in Shanghai University of Medicine & Health Sciences Affiliated Zhoupu Hospital were included in the study randomly,and divided into NAFLD group (27cases) and normal control group (57cases) though liver ultrasound examination.Their general data (sex,height,weight),liver function,blood lipid,and blood glucose were analyzed.The level of NLRP3 in peripheral blood was analyzed by ELISA double antibody sandwich method.The relationship between NLRP3 and NAFLD was analyzed by Logistic regression.Results The prevalence of NAFLD was 32.1 ％ (27/84).The levels of serum cholesterol,triglyceride,low density lipoprotein cholesterol,fasting blood sugar,alanine aminotransferase,creatinine and uric acid in NAFLD group were higher than those in normal control group (all P＜0.01),while the level of serum high density lipoprotein cholesterol was lower than that in normal control group (P=0.023);the concentration of serum NLRP3 in NAFLD group was (5.1±1.8) μg/L,and that in normal control group was (3.9±1.4) μg/L.There was significant difference between the two groups (t =6.221,P =0.016).Logistic regression analysis showed that NLRP3 was a risk factor for NAFLD (OR =1.537,P =0.021).Conclusion The level of NLRP3 is up-regulated in the serum of NAFLD patients,which is related to the occurrence of NAFLD.

Objective To evaluate the effect of aerobic exercise combined with resistance exercise on blood sugar and constitution in patients with type 2 diabetes mellitus.Methods Fifty eligible subjects in community type 2 diabetes database were randomly selected and a model intervention group of＂1+2+1＂ was established.The regular exercise intervention was conducted for six months by combining aerobic exercise with resistance exercise.The fasting blood sugar,blood pressure,heart rate,body mass and fat mass before and after intervention were compared by paired t test.Changes in related physical indicators.Results After 6 month of exercise therapy,fasting blood glucose of subjects reduced from (8.58±4.40) mmol／L to (6.29 ±1.72) mmol／L(P＝0.032).Body weight also reduced from (62.44±7.35) Kg to (60.70±7.54) Kg(P＝0.008). In physical quality related indexes, fat mass decreased significantly, while protein content increased significantly.There were no changes in muscle mass and fat free body weight.In addition, grip strength and flexion range of subjects significantly increased after exercise therapy.Comprehensive score of physical quality of subjects increased from (73.25± 5.65) to (75.48± 5.04) ( P＝0.010).Conclusion Exercise therapy of aerobic exercise combined with resistant exercise can effectively reduce blood glucose, body weight and fat mass,increase muscle strength,flexibility and physical quality.This also reflects that the community?led ＂health and physical integration＂ mode of work is an effective means to manage chronic diseases and enhance the physical fitness of residents.
