Objective To evaluate total laparoscopic splenectomy combined with pericardial devascularization. Methods In this study,40 patients with portal hypertension and hypersplenism underwent total laparoscopic splenectomy combined with pericardial devascularization,in which 26 cases had a history of up-GI bleeding. Results Procedures were successful in 36 patients.There was four conversions to open surgery.The operations were completed in a mean time of (224 ± 54) min,with a mean estimated blood loss of (296 ± 209) ml and with no serious complication. Conclusion Total laparoscopic splenectomy combined with pericardial devascularization is a safe and effective available minimally invasive procedure in patients with portal hypertension and hypersplenism.

Objective To review our clinical experience on 12 patients with retroperitoneal infection who were treated with retroperitoneal laparoscopic debridement.Method This retrospective study included 12 patients with retroperitoneal infection who were treated with retroperitoneal laparoscopic dehridement and drainage.Results All the 12 patients recovered well and were finally discharged home.Conclusions Retroperitoneal laparoscopic debridement and drainage for retroperitoneal infection is a mini-invasive procedure.It was found to be safe,produced minimal bleeding and resulted in rapid postoperative recovery.It can be used as the first choice treatment in properly selected patients.

AIM:To investigate the role of danshensu on Smad signal transduction in rat hepatic stellate cells(HSCs)stimulated with transforming growth factor(TGF-?1).METHODS:The rat HSCs was isolated with collagenase by in situ-liver recirculation perfusion and cultured in vitro.MTT colorimetric assay was used to detect proliferation of HSCs treated with different concentration of danshensu.The expressions of ?-SMA and T?R I and II were observed by immunocytochemitry,indirect immunofluorescent staining and Western blotting when HSCs stimulated with TGF-?1 and with different concentrations of danshensu for 24 h.RESULTS:(1)Danshensu at the concentration from 0.0625 mmol/L to 1 mmol/L prevented the proliferation of HSCs in a dose-dependent manner(P

Objectives: To investigate the effects of adhesion and proliferation of bone mesenchymal stem cells (BMSCs) in the surface of lactic acid/glycolic acid/asparagic acid-co-polyethylene glycol PLGA-[ASP-PEG] tri-block polymer scaffolds, try to find a new biomaterial to induce seed cells in vitro for bone tissue engineering. Methods: Modified PLGA with polyethylene glycol (PEG) and asparagic acid (ASP) that has many ligands, and synthesis PLGA-[ASP-PEG] polymer material. BMSCs were cultured in PLGA-[ASP-PEG] polymer material and PLGA used as control group. Through precipitation method, MTT assay and total cellular protein detection to test the adhersion and proliferation of BMSCs. Scanning electron microscope is used to observe cells appearance. Results: BMSCs on the surface of PLGA-[ASP-PEG] polymer scaffolds are adherention to the culture flask, the number of cells is much higher than PLGA’s. The precipitation method suggest that adhesion and proliferation of BMSCs on the surface of PLGA-[ASP-PEG] is much higher than the control group(P

The viral RNA was extracted from purified cymbidium mosa ic virus (CyMV) isolated from Dendrobium orchid cultivated in Hainan island. The gene of the movement protein (MP) was amplified by means of reverse transcripti on-polymerase chain reaction (RT-PCR), and cloned into pGEM-T easy vector. Se quence analysis showed that the gene fragment contained 3 open reading frames (O RFs) which may be encoding 14 kD、12 kD and 10 kD peptides. The nucleotide seque nce of the cloned gene fragment shared 97.8% homology with the MP genes of CyMV isolated from orchids cultivated in Hawaii and Singapore.

Objective To evaluate the effect of obesity on the incidence of surgical site infection (SSI) in patients with inguinal hernia after tensionless repair and its treatment.Methods Clinical data of 628 cases with inguinal hernia undergoing tensionless repair from Sep.2008 to May.2016 were retrospectively analyzed.The 628 patients were divided into obesity group (n=150) and non-obesity group (n=478),or SSI group (n=9) and non-SSI group(n=619).The effect of obesity on SSI after inguinal hernia and its treatment was analyzed.Re sults Among the 628 patients,SSC happened to 9 patients and the incidence was 1.43％.The rate of SSI in obesity group and non-obesity group was 4.00％ (6/150) and 0.63％ (3/478),respectively (x=6.960,P=0.002).BMI was 30.92±3.03 and 26.24±3.79 respectively in SSI group and non-SSI group (t=3.686,P=0.000).The difference has statistical significance.Factors such as diabetes,age,sex,albumin levels,American society of anesthesiology (ASA),type of hernia,method and duration of operation had no significant difference between SSI group and non-SSI group (P＞0.05).Conclusion By analyzing the risk factors of SSI after tensionless hernia repair,we find that patients with obesity are more likely to have SSI.Strengthening prevention and early treatment is a key measure to prevent postoperative infection in these patients.

Objective To analyze the feasibility of body surface electrodes instead of multipair esophageal electrodes for the evaluation of neural respiratory drive in patients with COPD. Methods Diaphragm electromyo-gram(EMG)from body surface electrodes and multipair esophageal electrodes,was recorded in 29 patients with stable COPD recruited from outpatient clinic. Changes of neural respiratory drive of two kinds of electrodes during resting and maximal isocapnic ventilation (MIV) were observed before and after inhalation of bronchodilators. Results Ventilation significantly improved ,RMS-sur and RMS-eso significantly decreased after the inhalation of bronchodilators during resting and MIV. RMS-sur and RMS-eso were significantly correlated(r=0.660,P<0.01). Conclusion EMG from the surface electrodes may be a useful and noninvasive technique to evaluate neural respi-ratory drive in patients with COPD.

Objective:Under innovative use of multiple payment mode,to ensure the safety of hospitals' fund based on the optimization of hospital outpatient progress and the implementation of financial internal management.Methods:Through the research related to use,operation of other units and repeated communication among hospital departments,it comprehensively summarized the internal management of multiple payment modes and enhanced the design management control of process based on information network technique.Results:Under the multi-payment mode,the hospital fund security was controlled under the continuous optimization informarion process.Conclusion:The application of multiple payment modes put forward new requirenents for the internal control management of hospitals,and ensured the safety of hospital funds through continuous improvement of internal control management.
