ABSTRACT
Objective To study the effect of different types of dyslipidemia on heart rate variability in patients with type 2 diabetes.Methods Cohort study was carried out at Renmin Hospital of Wuhan University during January 2014 to May 2016.Total 725 patients with type 2 diabetes were recruited,including 231 patients without dyslipidemia and 494 patients with dyslipidemia.Clinical parameters were collected from electronic medical records system.Using variance analysis,chi square test,Pearson correlation analysis and partial correlation analysis,we explored an association of different types of dyslipidemia and heart rate variability in patients with type 2 diabetes.Results TG,LDL-C,HDL-C,TG + HDL-C group significantly decreased heart rate variability compared group without dyslipidemia (P < 0.05).But the partial correlation analysis showed that only atherogenic index of plasma and Triglyceride (TG) were negatively correlated with heart rate variability,HDL cholesterol was positively correlated with heart rate variability,and the difference was statistically significant (P < 0.05).Conclusion Triglyceride (TG),atherogenic index of plasma(AIP),HDL cholesterol were related to the reduction heart rate variability in patents with type 2 diabetes.
ABSTRACT
Objective To compare the efficacy of empagliflozin and DDP4 inhibitors in the treatment of type 2 diabetes mellitus.Methods With Computer,we retrieval PubMed,Cochrane Library,EMbase,CNKI,CBM and Wanfang database to find all of the randomized controlled trials about the effectiveness and safety of empagliflozin and DDP4 inhibitors in the treatment of type 2 diabetes mellitus.The retrieval time was from the establishment of database to March,2016.References screen were performed manually.Meta-analysis was carried out using RevMan 5.2 software.Results A total of five studies included 1935 cases.The Meta analysis results showed that:HbA1c level (MD =-0.07,95% CI:-0.13--0.01,P <0.05),fasting blood glucose (MD =-16.73,95% CI:-21.02--12.43,P < 0.01),weight loss level (MD =-2.43 95% CI:-2.68--2.19,P < 0.01) in the two groups showed statistically significant differences.Empagliflozin group was better than DDP4 inhibitors group in reducing HbA1c level,fasting blood glucose,weight loss level.Safety:hypoglycemia between the two groups were similar (OR =0.86,95% CI:0.46-1.6,P > 0.05).Empagliflozin group's genital tract infection rate was statistically significant higher than that of DDP4 inhibitors.(OR =2.85,95% CI:1.71-4.76,P < 0.01).Conclusion Empagliflozin can effectively reduce the fasting blood glucose,HbAIc,and body weight,but increase the incidence of genital infection compare with DDP4 inhibitors.
ABSTRACT
Objective To explore the impacts of subclinical hypothyroidism (SCH) on chronic complications of type 2 diabetes mellitus. Methods Totally 448 patients with type 2 diabetes were divided into diabetes plus SCH group (n=148) and control group (T2DM without SCH,n=300).The patient's general information,past medical history,chronic complications of diabetes including diabetic nephropathy ( DN ), diabetic retinopathy ( DR), diabetic peripheral neuropathy ( DPN ),peripheral arterial disease (PAD),diabetic foot (DF),ancillary and laboratory test results were analyzed. Results The age,duration of diabetes,incidence of coronary heart disease and levels of fasting C-peptide,total cholesterol,triacylglycerol,lipoprotein (a),hs-CRP,LDL-C,UAER and thyroid stimulating hormone (TSH) [(6.8 ± 3.5) mIU/L vs. (2.1 ± 1.3) mlU/L], antithyroidperoxidase antibody (TPO-Ab) [(253.6 ± 287.1 ) kU/L vs. (46.2 ± 80.7)] kU/L and thyroglobulin antibodies (TG-Ab) [( 57.8 ± 83.5 ) kU/L vs. ( 39.4 ± 45.3 ) kU/L] were significantly higher,but the ankle brachial index(ABI) and E/A value were lower in diabetes plus SCH group than in control group (P<0.01 or 0.05).The prevalences of DN( 63% vs.46%,P<0.01),DR (40%vs.29%,P<0.05),DPN (34% vs.24%,P<0.05),PAD (51% vs.38%,P<0.05) and DF (22% vs.12%,P<0.01) were higher in diabetes plus SCH group than in control group.Logistic regression analysis demonstrated that high level of TSH was independent risk factor for DN(β=0.1273,OR =1.1361) and DF (β=0.1153, OR =1.1222). Conclusions Subclinical hypothyroidism is an independent risk factor for diabetic nephropathy and diabetic foot,so the elderly with longer duration of diabetes should regularly be checked in thyroid ffunction to early find hypothyroidism.
ABSTRACT
Objective To investigate the relationship between serum leptin and carotid intima-media thickness in patients with type 2 diabetes mellitus. Methods 35 patients with type 2 diabetes mellitus (DM) and 16 normal controls were studied. Fasting serum leptin, fasting glucose(FBG), HbAlc, C-peptide, lipide, systolic(SBP), diastolic blood pressure(DBP), body mass index (BMI) and waist circ-umference (WC) were measured in all subjects. The intima-media thickness (IMT) of common carotid artery was measured by high-resolu-tion ultrasound imaging. Results IMT of T2DM was positively correlated with leptin concentration. Conclusion Serum leptin concentra-tion is independently associated with the IMT of carotid artery, which suggest that leptin may be an independent risk factor of atherosclerosis.
ABSTRACT
Objective To explore the association of serum high-sensitivity C reactive protein (hs-CRP) level with leptin in patients with type 2 diabetes mellitns (T2DM). Methods 35 cases of T2DM patients were involved in the study and 16 normal subjects were taken as controls. Fasting serum leptin and CRP were measured .The relationship between them were also analyzed. Results Fasting serum hs-CRP concentration in T2DM group was higher than that in healthy control group, but serum ieptin levels is the same (P > 0.05). Partial correlation analysis demonstrated that fasting hs-CRP level was positively correlated with leptin (r =0.512 ,P =0. 018). Conclusion Fasting serum hs-CRP level is significantly raised in T2DM ,which is associated with leptin. There is chronic inflammatory reaction in T2DM patients,and leptin is possibly involved in inflammatory pathogenesis of T2DM.
ABSTRACT
BACKGROUND: The morbidity of diabetes mellitus increased recently.There are few reports about the pulmonary function status of the patients with diabetes mellitus.OBJECTIVE: To comparably observe the difference of the pulmonary function status between patients with diabetes mellitus and normal persons,and to probe into the relationship between the course of disease of diabetes mellitus and the functional change of pulmonary function.DESIGN: Case controlled observation SETTING: Renmin Hospital, Wuhan University PARTICIPANTS: Totally 90 patients with diabetes mellitus hospitalized in the Renmin Hospital, Wuhan University between January 2000 and De cember 2003 were recruited. All the patients participated in the experiment voluntarily. Totally 20 cases were of insulin dependent diabetes mellitns (IDDM) and 70 cases were of non-insulin dependent diabetes mellitus (NIDDM). Another 90 cases were divided into 2 groups with the boundary line of 10 years: group with disease course <10 years (n=40) and group with disease course >10 years (n=50). And 30 normal persons with healthy pulmonary function was set as healthy control group, all the testees were voluntary participants in the experiment.METHODS: Pulmonary function index of the participants of each group was measured: vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1%), peak expiratory flow rate(PEFR)maximal voluntary ventilation (MVV) and comparison was performed between them.Comparison of the pulmonary function status of the patients between different levels of diabetes mellitus.pulmonary function between different groups : Compared with health control group, VC , FVC and MVV of the patients with diabetes mellitus was significantly decreased (t=1.999-2.301, P < 0.05).There was no significant difference in the VC, FVC and MVV between patients with monary function between patients with different diabetes mellitus: the pulmonary function status in the group with disease course >10 years was improved less than that in the group with disease course <10 years [ VC (L):2.62±0.65 vs 3.25±1.25;FVC(L): 2.40±0.52 vs 3.21±0.98;FEV1%:75.31±2.31 vs 80.63±5.56;PEFR (L/s):4.33±0.68 vs 5.98±1.02;MVV (L/s): 76.22±6.98 vs 89.21±5.69 (t=2.012-2.350, P < 0.05)].CONCLUSION: Pulmonary function of the patients with diabetes mellitus has reduced tendency compared with the normal persons, and the pulmonary function of the patients with long course of disease decreases significantly. More attention should be paid to diabetes patients' pulmonary function changes.

ABSTRACT
AIM: To explore the change of the amount of GLUT4 protein at the plasma membrane of the rat skeletal muscle after high-fat feeding. METHODS: The animals were divided into three groups (ten for each): group I: control; group II: high-fat feeding; group III: high-fat feeding + dietary treatment. The rat model of insulin resistance (IR) was made by feeding high-fat diet for eight weeks. And then insulin-resistant rats were fed with chow diet for 4 weeks. Fasting plasma glucose and fasting serum insulin levels were measured before and after dietary treatment, respectively. Insulin treatment was achieved by intraperitoneal injection of insulin (10 unit insulin per kg body weight) 15 minutes before killing the animals. The right hindlimb skeletal muscle was rapidly dissected. Then the expression of GLUT4 protein at the plasma membrane in all the animals was assessed with Western bloting. RESULTS: The GLUT4 content at the plasma membrane in high-fat-fed rat skeletal muscle was significantly lower (about 31%) than that in controls (P
