Objective To study the effect of aquaporin 1 on intestinal capillary endothelial barrier in rats with experimental acute necrotizing pancreatitis (ANP).Methods In this study,160 male Sprague-Dawley rats were randomly divided into five groups:Control group ( n =32),ANP group (n =32),NS group,Dexamethasone group,and Acetazolamide group.Eight rats in each group were sacrificed at 3,6,12 and 18 h after induction of experimental models.Volume of ascites and levels of serum amylases were deternined at each time point.Pathological changes in intestine tissues were observed under electron microscope after HE staining.Capillary permeeabilities in intestine tissues were detected by Evans blue (EB) extravasation experiment.The mRNA and protein expressions of AQP1 in intestine tissue were determined by real-time PCR and Western blotting,respectively.Results Serum amylase level in ANP group was significantly higher than that in control group.Amylase level in dexamethasone group was lower than that in ANP group,and amylase level in acetazolamide group was higher than that in ANP group at 12 h (P <0.05 ) ; The concentration of EB in intestine tissues at each time point in ANP group was significantly higher than those in control group,and EB in dexamethasone group was lower than those in ANP group at 6,12 and 18 h.EB in acetazolamide group was higher than that in ANP group at 3 h ( P < 0.05 ) ; The mRNA expression of AQPI in ANP group was significantly lower than that in control group.The expression of AQP1 in dexamethasone group was higher than those in ANP group at 6,12 and 18 h,and the expression of AQP1 in acetazolamide group was lower than that in ANP group at 3,6,12 h in intestine tissue ( P < 0.05 ).Protein expression of AQPI in tissues in ANP group was significantly lower than that in control group.The expression of AQP1 in dexamethasone group increased more than that in ANP group at 3,6,12 h,and the expression of AQP1 in acetazolamide group was lower than that in ANP group at 3 h,6 h ( P < 0.05 ).Conclusions The expression of AQP1 is down-regulated in intestine tissue in rats with acute necrotizing pancreatitis,and AQP1 could play an important role in the pathogenesis of capillary endothelial barrier dysfunction.

Objective To probe into the medical experience in inpatients by tracking method,in order to provide the basis for continuing quality improve.Methods The tracking group was established,the patients was tracking and selected in medicine department,surgery departments,gynecology and obstetrical departments randomly from July to December 2015,and improve continually according to the feedback questions by patients,and then compared patient′s satisfaction.Results The members of tacking group interviewed patients 180 cases totally,and the patients had 152 times asked questions which included the contents as diet, environment,education,services and facilities. After improving continually,the questions asked by patients reduced from 105 times (in the third season) to 47 times (in the fourth season);the patient′s satisfaction improve from 97.39% to 99.22% (χ2=15.34,P<0.01).Conclusions The tacking method is used to daily nursing management for improving patient′s satisfaction,which can provide evidence to improve nursing quality.
