Objective To analyze the effects of dengue virus 2 ( DENV-2 ) infection on the ex-pression of IL-29 in primary human umbilical vein endothelial cells ( HUVECs) cultured on hydrogel sub-strates .Methods Primary HUVECs were isolated and cultured on hydrogel substrates .DENV-2 stains were used to infect the primary HUVECs at a multiplicity of infection( MOI) of 10.Flow cytometry analysis was performed to detect the apoptosis and infection rate of HUVECs after 48 hours of culturing .The gene chip profiling was performed to analyze mRNA expression .The expression of IL-29 at mRNA and protein levels were measured by real-time fluorescent quantitative PCR analysis and double antibody sandwich ELISA as -say, respectively.Results Compared with 96.36%of baby hamster kidney (BHK) cells that were infected with DENV-2 stains, only 4.71%primary HUVECs cultured on hydrogel substrates were infected .The pri-mary HUVECs cultured on hydrogel substrates with or without DENV-2 infection showed no significant differ-ences with the rates of cell apoptosis and infection (P>0.05).A significant difference was observed with the expression of IL-29 at mRNA level between primary HUVECs cultured on hydrogel substrates and the cells cultured in plastic bottles (P<0.05).The results of the real-time quantitative PCR analysis and ELISA as-say showed that IL-29 was highly expressed in DENV-2 infected primary HUVECs cultured on hydrogel sub-strates as compared with those in control groups (P<0.05).Conclusion The expression of IL-29 was de-tected in DENV-2 infected primary HUVECs cultured on hydrogel substrates , which was significantly differ-ent from that in DENV-2 infected primary HUVECs cultured in plastic bottles .The successful establishment of hydrogel substrates as the model of vascular basement membranes might provide a new way for the investi -gation of the pathogenesis of DENV infection .

Objective To investigate the effects of substrate stiffness on the proliferation of human umbilical vein endothelial cells ( HUVEC) during dengue virus infection.Methods Polyacrylamide gels were prepared for cell culture [(0±4) kPa].The proliferation of HUVEC cultured on substrates with differ-ent stiffness was determined by using 3-(4,5-diethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfo-phenyl)-2H-etrazolium,inner salt ( MTS) assay.The cycle and apoptosis of HUVEC were determined by flow cytometry analysis.Dengue virus serotype 2 (DENV-2) strains were propagated and identified by con-ventional assays.The HUVEC were infected with DENV-2 strains at a MOI of 10 and cultured on traditional plastic and hydrogel substrates, respectively.The levels of nitric oxide (NO) and endothelin-1 (ET-1) were detected by nitric acid reductase assay and double antibody sandwich ELISA.Results Young′s modulus E value of the hydrogels was (3030 ±0.44) Pa.The proliferation of HUVEC and the expression of NO and ET-1 were enhanced along the increased substrate stiffness.However, no significant differences with the cell cycle and apoptosis were observed between cells cultured on different substrates.Conclusion The stiffness of substrates affected not only the proliferation of HUVEC, but also the release of cytokines during DENV-2 infection.The development of dengue fever was associated with the decreased secretion of vascular active substances as a result of blood vessel injury.The establishment of hydrogel substrates as the model of vascu-lar basement membranes might provide a new way for the in vitro investigation of the pathogenesis of DENV infection.

Objective: To study the fluid distribution abnormalities in patients on hemodialysis and fluid shift between intracellular and extracellular compartment during hemodialysis (HD).Methods: Eighty stable end stage renal disease patients on maintenance hemodialysis were selected. Conventional low flux dialyses at dialysate sodium concentration of 138 mmoL/L were performed for all of the patients. Fresenius polysulphons or Gambro hemophon dialyzers were used. All of the patients showed no clinical signs of over ultrafiltration during HD sessions and dry body weights were considered adequate. Intracellular water (ICW), extracellular water (ECW) and total body water (TBW) were measured and standardized by body weight (nICW, nECW, nTBW) before and after HD sessions. Sixty-seven cases of sex, age and body weight matched normal individuals were used as controls. Bio-impedance spectrum (BIS) analysis (Xitron, Technolo gies, San Diego, CA, USA) was used in body fluid measurement. Pre and post HD nICW, nECW, and nTBW were compared with these of the controls.Results: There were no differences in age, post-dialysis body weight and body mass index between patients on hemodialysis and the controls. Patients on hemodialysis had less nICW [male (0.28?0.05) vs (0.33?0.04), P

Objective:To propose a method to evaluate the total body water (TBW) of patients on hemodialysis with urea kinetic model (UKM), and compare it with body surface bio-impedance spectrum (BIS) analysis. Methods:We enrolled 24 adult patients with end stage renal disease (ESRD) without hyper-catabolism in our dialysis center. All of them had been on hemodialysis for more than 3 months. TBW was measured with BIS analysis immediately before and after dialysis session, and one hour after hemodialysis session. Spent dialysate was collected; blood samples were taken before and one hour after hemodialysis session, TBW before hemodialysis session were calculated by UKM. Results:Patients were 6 men and 18 women, the average age was (51.2?13.5) years and the average time on dialysis was (33.2?36.7) months. Causes of ESRD included chronic glomerulonephritis (8 patients), diabetic nephropathy (1 patients), hypertensive renal damage (1 patients), interstitial nephritis(two patients), chronic pyelonephritis (two patients). The average ultrafiltration volume was (2.7?1.0) L (0.5-4.4 L) . Plasma urea concentrations were (23.06?5.76) mmol/L and (8.15?2.06) mmol/L before and one hour after hemodialysis session, respectively. There was no significant difference between TBW measured immediately after and one hour after hemodialysis session with BIS analysis [(29.9?8.8) L and (29.8?8.6) L, respectively; average difference was (0.1?0.9)L, P=0.70]. These two measurements correlated very well (Pearson r=0.99, P

Objective:To explore the application and nursing of protein A immunosorbent in patients with neuromyelitis optica spectrum diseases.Methods:Ten patients with neuromyelitis optica spectrum diseases were treated with protein A immunoadsorption therapy. Psychological nursing was emphasized. Comprehensive evaluation was conducted before adsorption to determine the prescription of adsorption therapy. During adsorption therapy, hypotension, membrane rupture and hemolysis of plasma separator, shivering and other adverse reactions were accurately prevented and treated. After treatment, attention should be paid to the prevention of nosocomial infection, regeneration and preservation of adsorption column.Results:After immunoadsorption therapy, the serum IgG level, antibody and EDSS score of 10 patients decreased to varying degrees. The serum IgG decreased from (6.04±2.77)g/L to (2.23±1.74)g/L. No serious complications occurred, no failure of immunosorbent operation, and the patients′ condition was better than before.Conclusions:Protein A immunosorbent therapy for neuromyelitis optica spectrum diseases is safe and effective. Standardized evaluation, operation and nursing are the key to achieve good results.

Background:As postoperative intra-abdominal septic complications( IASCs)in Crohn’s disease( CD)are difficult to manage,it is of great importance to prevent this condition in CD patients after surgery. Till now,there are no large sample studies on risk factors for postoperative IASCs in CD in China. Aims:To determine the risk factors for postoperative IASCs in CD for guiding the formulation of preventive strategies. Methods:This retrospective study was based on a computerized database of CD patients who had undergone surgery for CD complications between 1999 and 2014 at Nanjing General Hospital of Nanjing Military Command,PLA. Patients were divided into IASCs group and non-IASCs group. Thirty potential variables were selected,and both univariate and multivariate( Logistic regression)analyses were performed to identify the risk factors for IASCs after surgery. Results:Seven hundred and sixteen operations were reviewed,and IASCs occurred in 41 cases(5. 7%). By univariate and multivariate analyses,IASCs were significantly associated with one stage anastomosis(OR=1. 656,95% CI:1261-3. 279),preoperative low albumin level( <30 g/L)(OR=1. 457,95% CI:1. 152-2. 368),preoperative high CRP level( >10 mg/L)(OR=8. 641,95% CI:3. 376-16. 364),preoperative steroids use ≥3 months(OR=3. 785,95% CI:1. 237-4. 671)and presence of intra-abdominal abscess or infection at the time of surgery(OR=1. 784,95% CI:1. 155-3. 826). However,enterostomy(OR =0. 125,95% CI:0. 062-0. 561)and preoperative enteral nutrition ≥ 1 month( OR =0. 147,95% CI:0. 078-0. 781 ) were found to be the independent protective factors. Conclusions:Malnutrition,active CD and preoperative long-term steroids use increase the risk of postoperative IASCs in CD. Patients with these risk factors should not receive immediate surgery. If surgery is inevitable, enterostomy instead of resection and anastomosis should be the first choice. Preoperative enteral nutrition is helpful for reducing the occurrence of IASCs after surgery.
