RESUMO
Objective To study the eorrelation between the plasma cardiotrophin-1(CT-1)level and cardiac function of patients with diabetic cardiopathy.Methods Using the Biotin-StreptAvidin-enzyme-linked immunosorbent assay(BSA-ELISA),the level of plasma CT-1 jn 35 normal controls,40 patients with type 2 diabetes and 60 patients with diabetic cardiopathy was measured.The relation to heart function was observed.Results The difference of plasma CT-1 level in the three groups was significant(all P＜0.05).The level of plasma CT-1 in diabetic cardiopathy group was apparently higher than that of type 2 diabetes group and normal controls(all P＜0.01);The level in type 2 diabetes group was significantly higher than that of normal controls(P＜0.01).The level of plasma CT-1 elevated with the worsening of heart failure(NYHA classification).The level of plasma CT-1 was correlated with EF(r=0.669,P＜0.01);LAD(r=0.528,P＜0.01);PVE(r=0.502,P＜0.01);CK-MB(r=0.312,P＜0.01);TG(r=0.187,P＜0.05);DBP(r=0.158,P＜0.05)o Stepwise regression analysis revealed that EF and LAD were the most significant agents affecting the plasma CT-1.Conclusion The plasma CT-1 level could reflect the state of cardiac function of diabetic cardiopathy patient,it could help to diagnose diabetic cardiopathy earlier.
RESUMO
Objectives To investigate the epidemiological and clinical characteristics of dyslipidemia as well as its treatment and influence on accompanying diseases in impaired glucose status among inpatients. Methods A cross-sectional survey was conducted among the inpatients registered in ten university hospitals of Guangdong, China during the week before the Diabetes Day in 2004. The fasting blood glucose (FBG), lipid profiles, BMI, waist to hip ratio (WHR) and concomitant disorders of the first screen during the hospitalization period were recorded. Those who had FBG level from 5.6 to 6. 9 mmol/L and not been previously diagnosed diabetes (PDM) underwent oral glucose tolerance test (OGTF). Results Of the 8753 inpatients investigated, 1067 eases had complete medical records(CMR case) including PDM cases and previously non-diagnosed diabetes ones with FBG ≥ 5. 6 mmol/L. Of the previously non-diagnosed diabetes cases with FBG levels from 5.6 to 6.9 mmmol/L, 65.8% accepted OGTT. Of the CMR cases, 41.9% had PDM, 21.7% was newly diagnosed diabetes mellitus (NDM), 29. 1% had impaired glucose regulation (IGR) and only 7.3% had normal glucose tolerance (NGT). The TG levels in NDM and PDM group were higher than those in IGR and NGT group (P < 0.05, respectively). The HDL-C levels in IGR, NDM and PDM group were lower than those in NGT group (P < 0.05, respectively). Sixty-nine point six percent of the diabetes mellitus (DM) inpatients was accompanied with dyslipidemia and the rate was higher than those in NGT (56.4%) and IGR inpatients (52.5%, P <0.05, respectively). Only 22. 8% of the PDM inpatients underwent treatment of dyslipidaemia and just 3.4% achieved the target suggested by the guideline of ATP-Ⅲ. BMI was higher and waistline longer in the PDM and NDM inpatients than those in the NGT cases (P <0.05, respectively). Seventy-two point eight percent of the PDM inpatients was complicated with more than one type of vascular diseases. Nine point seven percent and 0. 2% of the NDM inpatients were tormented by diabetic nephropathy and diabetic retinopathy respectively. Conclusions More inpatients with accompany DM or IGR had concomitant dyslipidemia than those with NGT, which included hypertriglyccridemia, hypo-high-density lipoproteinemia and metabolic syndrome. Concomitant vascular diseases were more frequently found in PDM inpatients than in the others. Some of the NDM and IGT inpatients were complicated with microvascular diseases.
RESUMO
Magnetic motor evoked potentials (MEP) were measured in 46 patients with Graves′ disease (GD) and 50 normal controls, and its latency、amplitude and central motor conduction time (CMCT) were recorded. Prolonged latency, lowed amplitude and shortened CMCT in MEP suggest the damage of the neurons.
