Background: A lack of demographic and clinical data hinders efforts of health care providers in China to support patients with type 1 diabetes mellitus (T1D). Therefore, the aim of the present retrospective study was to provide an overview of the demographic and clinical characteristics of Chinese patients with T1D. Methods: Hospital medical records of patients with T1D (diagnosed between January 2000 and December 2011) in 105 secondary and tertiary hospitals across Guangdong province were reviewed. Data were collected on patient age at diagnosis, presentations at onset, physical examination, and diabetes management. Results: In all, 3173 patients diagnosed with T1D between January 2000 and December 2011 were included in the study (46.2% female). The median age at diagnosis was 27.5years (interquartile range [IQR] 18.0-38.0) years and the median body mass index (BMI) at onset was 19.6kg/m2 (IQR 17.4-21.8kg/m2). Among adult patients, 0.9% were obese, 6.6% were overweight, 62.3% were normal weight, and 30.3 % were underweight. The prevalence of diabetic ketoacidosis (DKA) at onset was 50.1%. The proportion of patients with retinopathy, nephropathy, and neuropathy was 8.1%, 20.7 %, and 11.1%, respectively. Conclusion: The adult-onset form of T1D is not rare in China. The registry participants were characterized by older age at onset, lower BMI, and a higher prevalence of DKA at onset compared with those in regions with a high incidence of T1D, such as northern Europe. These findings contribute to a better understanding of the heterogeneity of T1D in different populations and so will help healthcare providers to develop management models that are more suitable for these patients. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Thrombin and thrombin receptor activation impact cardiomyocyte contraction and ventricular remodeling. However, there is some controversy regarding their effects in cardiac function, especially in cardiac dysfunction after acute myocardial infarction (AMI). A rat AMI model was created by left coronary artery ligation (LCA). Cardiac functional parameters, including the maximum left ventricular (LV) systolic pressure (LVSPmax), LV end-diastolic pressure (LVEDP), and the rise and fall rates in LV pressure (dp/dt max and dp/dt min, respectively), were measured. Hirudin decreased cardiac function within 120 minutes after AMI, whereas treatment with thrombin receptor-activating peptide (TRAP) reversed this hirudin-induced decrease in cardiac function. The mRNA and protein expression levels of inositol 1,4,5-trisphosphate receptor (IP3R) subtypes in infarct area tissues were analyzed by reverse transcription-polymerase chain reaction and immunoreaction. Hirudin decreased the expression levels of IP3R-1, -2, and -3 in the infarct area for up to 40 minutes after AMI, whereas TRAP treatment reversed these hirudin-induced effects. Treatment with the IP3R antagonist 2-aminoethoxydiphenyl borate (2.5 mg/kg) eliminated the effect of TRAP on the hirudin-induced decrease in cardiac function after AMI. Finally, TRAP increased the maximum binding capacity of the three IP3R subtypes, but only enhanced the affinity of IP3R-2. Thrombin and thrombin receptor activation improved cardiac function after AMI by an IP3R-mediated pathway, probably through the IP3R-2 subtype.

High triglycerides and low high density lipoprotein cholesterol are important cardiovascular risk factors. Triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) has been reported to be useful in predicting cardiovascular disease. Brachial-ankle pulse wave velocity (baPWV) is a valid and reproducible measurement by which to assess arterial stiffness and a surrogate marker of atherosclerosis. However, there is limited evidence about the relationship between them. Therefore, we tested the hypotheses that TG/HDL-C is associated with baPWV in healthy individuals.Fasting lipid profiles, baPWV and clinical data were measured in 1498 apparently healthy, medication-free subjects (926 men, 572 women) who participated in a routine health screening from 2011 to 2013. Participants were stratified into quartiles of TG/HDL-C ratio. BaPWV > 1400 cm/s was defined as abnormal baPWV, Multivariable logistic regression was used to identify associations of TG/HDL-C quartiles and baPWV, after adjusting for the presence of conventional cardiovascular risk factors.In both genders, we observed positive relationships between TG/HDL-C quartiles and BMI, systolic BP, diastolic BP, fasting glucose, total cholesterol, LDL-C, triglycerides, uric acid, and percentages of high baPWV. Multivariable logistic regression revealed that baPWV abnormality OR value of the highest TG/HDL-C quartiles was 1.91 (95% CI: 1.11-3.30, P < 0.05) and 2.91 (95% CI: 1.02-8.30, P < 0.05) in male and female after adjusting for age, systolic BP, diastolic BP, BMI, fasting plasma glucose, LDL-C, uric acid and estimated glomerular filtration rate when compared with the lowest TG/HDL-C quartiles.Increased TG/HDL-C was independently associated with baPWV abnormality in apparently healthy individuals.
