Objective To explore the upstream signal transduction pathway of neutrophil elastase(NE)-induced mucin(MUC)5AC gene expression.Methods A549 cells were either incubated with NE alone or with DMTU,aprotinin or AG1478.The level of MUC5AC mRNA was measured with RT-PCR.The activation of epidermal growth factor receptor(EGFR) and signaling were assessed by measuring the release of epidermal growth factor(EGF) and the phosphorylation of EGFR.Results NE increased MUC5AC gene expression accompanied by an increase of EGF and phosphorylated EGFR.DMTU,aprotinin and AG1478 significantly inhibited MUC5AC gene expression.DMTU and aprotinin significantly decreased the level of EGF and phosphorylated EGFR.ConclusionNE can induce MUC5AC gene expression via EGFR signalling in A549 cells.The upper stream involves oxidants,activation of tissue kallikrein and EGF.

Objective To investigate the interrelationship among urinary albumin elimination rate(UAER),serum adiponectin(ADPN)and blood glucose level in patients with type 2 diabetic nephropathy(DN). Methods A total of 89 type 2 diabetic patients and 30 healthy people as control were enrolled in the study.According to UAER,the diabetic patients were divided into three groups:normal group(35 cases,UAER＜30 mg/24 h),microalbuminura group (32 cases,UAER 30-300 mg/24 h)and macroalbuminura group(22 cases,UAER＞300 mg/24 h).Serum adiponectin was measured by ELISA.Body mass index (BMI),waist hip radio(WHR),fasting plasma glucose(FPG),2-hour plasma glucose(2hPG),glycated haemoglobin(HbAlc),blood lipid and UAER were measured routinely.Data were compared among groups. Results Serum adiponectin level was lower in diabetic patients than that in healthy control group(P＜0.05).Among diabetic patients.serum adiponectin of macroalbuminura group was significantly higher than that of normal and microalbuminura groups[(67.74±14.89)vs(39.36±13.92),(54.38±10.14)ng/L,P＜0.051.Multiple regression analysis showed 2hPG,HbAlc,BMI,disease course,UAER and DBP were closely associated with the level of serum adiponectin. Correlation analysis indicated serum adiponectin was positively correlated with age (r=0.255), disease course (r=0.405), HDL (r=0.501)and UAER (r=0.843); while negatively with HbAlc (r=-0.479), FPG (r=-0.436), 2hPG(r=-0.418),BMI (r=-0.479) and WHR (r= -0.531), all P＜0.01. Conclusions Serum adiponectin is positively correlated with UAER and negatively correlated with FPG. Blood glucose level is one of the main factors affecting serum adiponectin. Strict controlling of blood glucose level is beneficial to higher level of ADPN.

Obiective To explore the dynamics of tidal breathing pulmonary function in infants with recurrent wheeze and its clinical signiifcance. Methods Eighty (80) infants with recurrent wheeze from October 2013 to February 2014 were enrolled and divided into asthma predictive index positive (n=25) and asthma predictive negative (n=55) groups, and another 20 healthy children were enrolled as control group. Tidal breath pulmonary function at the time of admission (acute phase), leaving hospital (remission phase), and a week after discharge (admission phase) were tested, the ratio of time taken to reach peak expiratory lfow to total expiratory time(TPTEF/TE)and ratio of peak expiratory volume to total expiratory volume(VPEF/VE) between groups were compared. Results From acute phase and remission phase to admission phase, TPTEF/TE, VPEF/VE were elevated in positive group and negative group showing signiifcant statistical difference between phases (P=0.000). In acute phase, TPTEF/TE, VPEF/VE showed no statistical difference (P>0.05) between positive group and negative group, when compared with control group, TPTEF/TE, VPEF/VE were signiifcantly lower in positive and negative groups than that in control group (P<0.05). In remission phase, TPTEF/TE, VPEF/VE in negative group were higher than that in positive group, but significantly lower than that in control group (P<0.05). In admission phase, TPTEF/TE and VPEF/VE in negative group and control group showed no statistical difference (P>0.05), but significantly higher than that in positive group (P<0.05). Conclusions Lung function impairment duration was longer in asthma predictive index positive children than in asthma predictive index negative children. The tidal breathing pulmonary function test can provide objective clinical indicators for infants with recurrent wheeze to predict asthma.
