Objective To elucidate the efficiency lncRNA GAS5 and miR-21 as biomarkers in diabetes mellitus and diabetic nephropathy.Methods The patients were divided into three groups,diabetic nephropathy group (DN group proven by renal biopsy,n=25,14 males and 11 females),diabetes group (DM group,with normal urine albumin creatinine ratio,n=10,4 males and 6 females),and normal control group (NC group,n=9,4 males and 5 females).The expressions of lncRNA GAS5 and miR-21 in serum samples were detected by real-time quantitative PCR.The correlation between serum lncRNA GAS5 and miR-21 expressions and the clinical parameters was analyzed by T-test,Pearson,Spearman test and multivariate linear regression analysis.Differences of lncRNA GAS5 and miR-21 in different groups were analyzed by one-way analysis of variance.The ROC curve was used to analyze the diagnostic efficacy of lncRNA GAS5 and miR-21 in diabetes and diabetic nephropathy.All data were analyzed by SPSS 20.0 and GraphPad software,with P ＜ 0.05 as considered statistically significant.Results (1) The expression of serum lncRNA GAS5 was significantly down-regulated and serum miR-21 was significantly up-regulated in both diabetes mellitus and diabetic nephropathy patients compared to the NC group all (P ＜ 0.05).(2) In DN patients,the expression of serum lncRNA GAS5 was gradually up-regulated along with the increment of 24 h urinary protein.The expression of serum miR-21 was gradually up-regulated along with renal biopsy stage Ⅱb-Ⅲ of DN (P ＜ 0.05).(3)FBG and HbA1c were all negatively correlated with serum lncRNA GAS5 (P ＜ 0.05),and FBG was independently correlated with serum lncRNA GAS5 (P ＜ 0.05).Urine microalbumin,Total cholesterol (TC),Scr,Urea and SBP were all positively correlated with serum miR-21(P ＜ 0.05).Albumin (ALB)and estimated GFR (eGFR) were negatively correlated with serum miR-21(P ＜ 0.05),and ALB was independently correlated with serum miR-21 (P ＜ 0.05).(4) The diagnostic efficiency of serum lncRNA GAS5,miR-21 and lncRNA GAS5/miR-21 as "diagnostic signature" for DM were was good (P ＜ 0.05).(5) The diagnostic efficiency of serum miR-21 and lncRNA GAS5/miR-21 as "diagnostic signature" for DN were was good (P ＜ 0.05).Conclusions (1) Serum lncRNA GAS5 had good diagnostic efficiency in diabetes mellitus.The sensitivity of lncRNA GAS5/miR-21 for diagnosis of diabetes was 85.71％,and specificity was 88.89％.(2) The level of serum miR-21 can be used as a noninvasive diagnostic marker for diabetic nephropathy.

Objective To detect the serum microRNA-148b-3p level in patients with diabetes mellitus and diabetic nephropathy,and to analyze its correlation with clinical and pathological indexes.Methods The research crowd was divided into three groups (1) diabetic nephropathy group:biopsy with diabetic nephropathy (n=25,14 males,11 females);(2) type 2 diabetes mellitus group:type 2 diabetes mellitus patients with normal urinary microalbumin/urinary creatinine value (n=10,4 males,6 females);(3) normal control group:healthy subjects (n=9,3 males and 6 females).Clinical indicators included gender,age,24-hour urine protein,systolic blood pressure (SBP),diastolic blood pressure (DBP),serum creatinine (Scr),urea (Urea),cystatin-C (Cys-C),blood albumin (ALB),urine microalbumin (UMA),triacylglycerol (TG),total cholesterol (TC),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C),serum uric acid (UA),fasting blood glucose (FBG),glycated hemoglobin (HbA1c),urine microalbuminuria / urinary creatinine (UACR),and estimated glomerular filtration rate (eGFR) calculated by CKD-EPI formula.Real-time quantitative PCR was applied to verify the expression of microRNA-148b-3p in serum samples of the research crowds.The relationships between microRNA-148b-3p level and clinical features was also analyzed.Results The levels of serum microRNA-148b-3p in diabetic nephropathy group and in type 2 diabetes mellitus group were 1.82 times and 1.73 times of that in normal control group (P ＜ 0.05,respectively).The level of serum microRNA-148b-3p was significantly correlated with HDL-C (r=-0.374,P=0.013),UMA (r=0.426,P=0.004),FBG (r=0.330,P=0.046) and TG (r=0.423,P=0.005).Multiple linear regression analysis showed that UMA level was independently associated with serum microRNA-148b-3p level (β=0.338,P=0.044).The area under the receiver operating characteristic curve (ROC) of serum microRNA-148b-3p in diagnosing type 2 diabetes mellitus and diabetic nephropathy was 0.835 and 0.665,respectively.Conclusions The level of serum microRNA-148b-3p of patients with type 2 diabetes mellitus or diabetic nephropathy significantly increases.The level of UMA is independently associated with serum microRNA-148b-3p level.Serum microRNA-148b-3p is expected to be a potential biomarker for the diagnosis of diabetic nephropathy.

Objective To investigate the significance of plasma levels of insulin-like growth factor(IGF)-1 and insulin-like growth factor binding protein(IGFBP)-3 in predicting acute respiratory distress syndrome(ARDS)and prognosis in critical patients.Methods A totally of 131 critical patients in intensive care unit(ICU)of the First Affiliated Hospital of Wenzhou Medical University were reviewed.Plasma concentrations of IGF-1,IGFBP-3,blood biochemistry,procalcitonin(PCT),lactic acid(LAC)and blood albumin were measured in enrolled patients.The 60-day fatality of enrolled patients was calculated.The differences between ARDS group and control group,as well as 60-day dead group and survival group were compared.Results Plasma IGF-1 and IGFBP-3 in ARDS group were significantly lower than those in control group,while plasma PCT was higher than that in control group.Plasma levels of IGF-1 and IGFBP-3 in dead group were significantly lower than those in survival group.Multivariate Logistic regression analysis and receiver operating characteristic curve results showed that IGF-1 area under curve(AUC)was 0.770,sequential organ failure assessment(SOFA)(AUC=0.692)and PCT(AUC=0.710)were independent risk factors for ARDS in critical patients.IGF-1(AUC=0.807),IGFBP-3(AUC=0.759)and SOFA score(AUC=0.859)were independent risk factors for death in critical patients.Conclusion The plasma levels of IGF-1 and IGFBP-3 in critica patients are significantly decreased,which may be an important factor for ARDS risk and fatality in critical patients.

The number of investigator initiated research (IIR) is increasing. But the recognition and management of IIR in China is still in its infancy, and there is a lack of specific and operable guidance for the implementation process. Based on our practical experiences, previous literature reports, and current policy regulations, the authors took prospective IIR as an example to summarize the implementation process of IIR into 14 steps, which are as the following: study initiation, ethical review, study registration, study filing, case report form design, database establishment, standard operating procedure making, investigator training, informed consent, data collection, data entry, data verification, data locking and data archiving.
