RESUMO

Objective:To investigate the risk factors of diabetic nephropathy (DN) in primary type 2 diabetes mellitus (T2DM) patients and to quantitatively analyze the risk of DN by nomogram modeling.Methods:A total of 1 588 primary T2DM patients from 17 townships and streets in Zhejiang Province were enrolled from June 2018 to August 2018 in this cross-sectional study, with an average age of (56.8±10.1) years (50.06% male) and a mean disease duration of 9 years. The clinical data, biochemical test results, and fundus photographs of all T2DM patients were collected, and logistic regression analysis was used to screen the risk factors of DN. Then, a nomogram model was used to quantitatively analyze the risk of DN.Results:DN occurred in 27.71% (440/1 588 cases) primary type 2 diabetes patients. Hemoglobin A 1c (HbA 1c) ( OR=1.159, 95% CI 1.039-1.292), systolic blood pressure ( OR=1.041, 95% CI 1.031-1.051), serum creatinine (Scr) ( OR=1.011, 95% CI 1.004-1.017), serum globulin (GLOB) ( OR=1.072, 95% CI 1.039-1.105), diabetic retinopathy (DR) ( OR=1.463, 95% CI 1.073-1.996), education level of more than junior high school ( OR=2.018, 95% CI 1.466-2.777), and moderate-intensity exercise ( OR=0.751, 95% CI 0.586-0.961) were influencing factors of DN. Nomogram model analysis showed that the total score of each factor of DN ranged from 64-138 points, and the corresponding risk rate ranged from 0.1-0.9. The nomogram model also predicted a C-index value of 0.753 (95% CI 0.726-0.781) and an area under the receiver operating characteristic curve of DN of 0.753. Internal verification of the C-index reached 0.738. The model displayed medium predictive power and could be applied in clinical practice. Conclusions:HbA 1c, systolic blood pressure, Scr, GLOB, DR, and more than a junior high school education are independent risk factors of DN. Nomogram modeling can more intuitively evaluate the risk of DN in primary T2DM patients.

RESUMO

Single-cell RNA sequencing (scRNA-seq) is used for transcriptome profiling at the individual cell level, which is capable of screening in differentially gene expression that results from genetic mutation. Islet-based developmental atlas and heterogeneity characterization are currently the main applications of scRNA-seq in diabetes. scRNA-seq also can be used to mark and purify the functional β cells from resident adult stem cells in the pancreatic islets, which is expected to improve the outcome of islet β cells transplantation in type 1 diabetic patients. In addition, the technique can aid in learning diabetic β cell dedifferentiation and immunomodulatory functions. Although the study of scRNA-seq in diabetic retinopathy, nephropathy, atherosclerosis, and peripheral neuropathy is still at a nascent stage, scRNA-seq has great potential in a wide range of biomedical and clinical applications.

RESUMO

Objective:To analysis the correlation of eating speed with obesity.Methods:A total of 644 people aged 40-65 from Caihe Community in Hangzhou were enrolled to collect clinical and demographic data, undergo extensive physical examination and laboratory tests. Participants were divided into two groups according to their eating speed (non-fast and fast). Obesity-related parameters were compared between two groups. Multivariable logistic regression was conducted to explore the relationship between eating speed and obesity after adjusting confounders.Results:Body mass index, waist circumference, and visceral fat area were greater in the fast eating group than non-fast eating group(all P<0.01). After adjusting for age, gender, smoking, alcohol drinking, physical activity level per week, and principal food intake, logistic regression analysis showed that eating fast was correlated with abdominal obesity( OR=1.66, 95% CI 1.11-2.48, P=0.014) and visceral obesity( OR=1.65, 95% CI 1.14-2.39, P=0.007). After stratified by gender, in the group of men, eating fast was correlated with abdominal obesity( OR=2.04, 95% CI 1.07-4.04, P=0.032) and visceral obesity( OR=1.85, 95% CI 1.04-3.31, P=0.037); In the group of women, eating fast was correlated with overweight and obesity( OR=1.59, 95% CI 1.04-2.42, P=0.031). Conclusion:Eating fast is positively associated with obesity. Interventions for reducing eating speed may be effective for weight control.

RESUMO

Metabolic syndrome (MetS) is characterized by a cluster of metabolic disorders including obesity, dyslipidemia, hyperglycemia, and hypertension. Here, we report that 27 microRNAs were found to be expressed differently in serum and urine samples of MetS patients compared to control subjects on microarray analysis. Further qualitative real time- polymerase chain reaction analyses confirmed that circulating levels of miR-143-3p were significantly elevated in MetS patients compared with controls, both in serum and urine samples. After accounting for confounding factors, high levels of miR-143-3p remained an independent risk factor for insulin resistance. Inhibition of miR-143-3p expression in mice protected against development of obesity-associated insulin resistance. Furthermore, we demonstrated that insulin-like growth factor 2 receptor (IGF2R) was among the target genes of miR-143-3p by searching 3 widely used bioinformatics databases and preliminary validation. Our experiments suggest that knockdown of circulating miR-143-3p may protect against insulin resistance in the setting of MetS via targeting of IGF2R and activation of the insulin signaling pathway. Our results characterize the miR-143-3p-IGF2R pathway as a potential target for the treatment of obesity-associated insulin resistance.

RESUMO

Maturity onset diabetes of the young (MODY) is a monogenic autosomal dominant inherited disease. Its clinical manifestations are asymptomatic with slightly elevated fasting blood glucose and few complications. This paper reports a novel mutation W257R in glucokinase () gene from a Chinese patient with MODY. Heterozygous mutation c.769T>C (p.W257R) in exon 7 of gene (Chr744187343) was found in the proband, her father and brother. This W257R mutation was first reported in Chinese population.
