Objective To investigate the method and nursing care of early enteral nutrition through naso-jejunal feeding tube for patients with severe acute pancreatitis.Methods We retrospectively studied 37 patients with severe acute pancreatitis,who were given early enteral nutrition through naso-jejunum nutrition tube.Results Abdominal distention occurred in 5 patients,and 3 patients got mild diarrhea.No aspiration and SAP relapse occurred among 37 patients.All the patients were discharged from hospital after recovery.Conclusions Enteral nutrition through naso-jejunum nutrition tube is the main treatment and nutritional support measure for patients with severe acute pancreatitis.Daily care of the naso-jejunum nutrition tube,and prevention and treatment of complications are the critical work in SAP patients＇ nursing care.

Background and purpose:The molecular regulation mechanism of the LCRG1 gnen is unclear;The study was designed to clarify the regulatory elements of LCRG1 gene in its 5'flanking region.Methods:Bioinformatics approaches were adopted and a putative promoter region was found in 5'flank upstream fragment of LCRG1 gene,5'flank upstream regulation fragment 1.776 kb(from-1 191 bp to +585 bp)of LCRG1 gene was amplified by PCR using genomic DNA as template,construct was obtained by cloning DNA fragments into pGL3 reporter vector.The construct was then introduced into COS7 cells by Lipofectemin method for transient expression of reporter gene,and luciferase activities was measured by luciferase assay.Results:The sequence of 5'flank upstream regulation fragment 1.776 kb(from-1 191 bp to +585 bp)of LCRG1 gene was successfully cloned and proved to be correct by DNA sequencing,the activity of pGL3-1776 was about 0.16-fold higher than that of pGL3-control cotransfection with PRL-TK and 35-fold higher than that of pGL3-basic cotransfection with PRL-TK.Conclusions:5'flank upstream regulation region 1.776 kb(from-1 191 bp to +585 bp)of LCRG1 was cloned successfully,the fragment presented promoter activity.

That hospital libraries purchase books and periodicals via bidding is necessitated by social development and is characterized by the following advantages: smashing monopoly operations and adopting competitive mechanisms; reducing intermediate links and speeding up the delivery of books and periodicals; avoiding missing issues of periodicals and ensuring the completeness of periodicals; bettering preferential treatment and saving funds; standardizing market competition and reducing job-related offenses; safeguarding the legitimate rights and interests of the libraries.

Objective To investigate the influence of gonadotropin releasing hormone agonist (GnRH-a) on the expression mRNA of nerve growth factor (NGF) and its receptors (TrkA and P75NTR) in normal and eutopic endometrial stromal cells (ESC).Methods From January to April 2009,3 patients with endometriosis undergoing surgery in Peking Union Medical College Hospital were obtained eutopic endometrium as study group matched with eutopic endometrium from 3 parents with teratoma as control group.ESC were incubated with different concentration of GnRH-a (0,5 × 10-11,5 × 10-10,5 × 10-9,5 ×10-8,5 × 10-7 g/ml).The expression of mRNA of NGF,TrkA and P75NTR were measured by real-time-PCR.Results At concentration of 0 g/ml,the levels of NGF,TrkA and P75NTR mRNA in ESC were 6.32,8.55,8.08 in study group,which were significantly higher than 0.94,0.67,1.08 in control group (P ＜0.05).Treated by the following concentration of GnRH-a (5 × 10-11,5 × 10-10,5 × 10-9,5 × 10-8,5 ×10-7 g/ml),the median expression of NGF,TrkA and P75NTR mRNA was 1.00,0.96,1.05; 1.09,0.82,1.27 ; 1.04,0.52,0.81 ; 1.00,0.55,0.64; 0.78,0.49,1.02 in study group.Compared with the expressions of those untreated by GnRH-a in study group, they showed significantly lower trends (P ＜0.05).In control group,the median expression of NGF,TrkA and P75NTR mRNA was 0.98,0.37,0.92; 0.70,0.45,1.15; 1.55,0.80,1.35; 1.09,0.41,1.35; 0.90,0.82,1.18.Compared with the expressions of those untreated by GnRH-a in control group,there were no statistically differences ( P ＞0.05).And treated by the same concentration of GnRH-a,the expressions of NGF,TrkA and P75NTR mRNA did not show statistically difference between the two groups ( P ＞ 0.05 ).Conclusion The expression of NGF.TrkA and P75NTR mRNA were suppressed by GnRH-a.

Objective This study aimed to explore the relationship between the traumatic experience in childhood and onset of obsession in adulthood,and the character of family environment of obsession patients.Methods Using Y-BOCS and CAT and FES-CV to evaluate 41 cases with OCD and 36 normal subjects respectively.Baaed on these scales,an edited interview schema for a semi-structured interview was choosed with both groups for 50 minutes respectively.Results ①Tbe whole score and scores of two subscales on punishment,negative-environment in CAT were all obviously higher in patients with obsession [(50.16± 21.03),(12.03±4.24),(19.77±9.74),for punishment:P<0.05,for others:P<0.01],and there were a significant difference in the two groups[(35.35±14.78),(9.92±2.51),(12.54±8.14)].The negative environment was chosen in regress equation,and could explain 14.67% of outcome of obsession. ②The scores of 4 ubacaies like cohesion,expressiveness,intellectual-cultural orientation,active-recreational orientation [(5.13±2.28),(4.10±2.12),(2.71±1.87),(2.52±2.34)] ,were all obviously lower than the normal control in FES-CV.While the subscore of conflict (5.03±2.21) was higher than the normal control(3.50±2.40),and all these differences were significant.When two factors of active-recreational orientation and cohesion in FES-CV were put into regression equation( R2 =0.2078 ,R2 =0.2784),they contribute 27.84% and the disease,and the active-recreational orientation factor can explain 20.78%.③The result of interview found significant difference between obsession groupand control group in parental personality,own personality,childhood experience,and family environment.Condusion The traumatic experience in childhood and unhealthy family environment do have association with onset and development of obsession,also they have a close relationship with the development of personality after adulthood.

Objective To discuss effect of different kinds of dressings on complications after periph-erally inserted central catheter(PICC). Methods Patients with skin hypersensitiveness after PICC adopt-ed sterile bandage and Anshutuo IV3000 transparent dressing to carry out local dressing change respective-ly. Incidence of catheter infection,slippage and complications were compared. Results The rate of catheter infection was 19.4%( 0 cases) and catheter slippage was 6.5%(7 cases) by using sterile bandage.While the rate of catheter infection was 3.2%(1 case) and catheter slippage was 3.2%(1 case) by using Aashutuo IV3000 transparent dressing. Conclusions Using Anshutuo IV3000 transparent dressing on local dressing change solved the shortcomings of common dressings and sterile bandage,reduced the inci-dence of complications after PICC and prolonged the using time of catheter.

Measures were taken to reform the current teaching mode including establishing cur-riculum system which embodies medical characteristics,exploring probation mode suitable for local med-ical college,setting up students' autonomous learning platform,improving performance evaluation meth-ods,teaching students in accordance with their aptitude,etc. Meanwhile,new partnership between school and hospital was explored though improving teaching management system. After taking above measures, students' practical ability was significantly enhanced and quality of teaching was improved.

With the development of CT technique and clinical application of mutiple-detector helical CT,it is possible to reconstruct the structure of organs under the help of 3-dimention CT technique.The blood supply of normal liver and that of hepatic cancer come from hepatic artery and portal vein,with 25% and 75% respectively for the former and just neverse for the latter and sometimes having correlation with presure inside ,the biliary system.Therefore,a full knowledge of intrahepatic vasculo-ductal system is not only crucial for hepatic cancer diagnosis but also for treatment interventionally.(J Intervent Radiol,2007,16:280-283)
