Objective To investigate the efficacy of transorally inserted anvil system(OrVilTM)in esophagogastrostomy and esophagojejunostomy after laparoscopic gastrectomy.Methods The clinical data of 34 patients with gastric neoplasms who were installed OrVilTM for esophagogastrostomy or esophagojejunostomy at the Changhai Hospital from July 2009 to February 2011 were retrospectively analyzed.After radical dissection of lymph nodes and full mobilization of esophagus,the esophagus was transected and the anvil was then transorally inserted into the esophagus by using the OrVilTB system.Double-stapling esophagogastrustomy or esophagojejunostomy with a circular stapler Was performed intracorporeally under direct laparuscopic view.Results The surgery was success fully completed in all the 34 patients with no conversion to open surgery.Two patients had difficulty in placing OrVilTM system.and the condition Was alleviated by reducing tension in the cuff and tilting the head back.The mean operation time,volume of blood loss,duration of postoperative hospital stay and time to gastrointestinal function recovery were 175 minutes(range,90-240 minutes),196 ml(range,50-800 ml),7.6 days(range,5-14 days)and 3 days(range,2-6 days).No postoperative anastomotic leakage Was detected.Thirty-three patients were followed up for 2-20 months with a mean time of(10±6)months,and no tumor recurrence or metastasis occurred.Conclusion OrVilTM system changes insert direction of the anvil,which significantly reduces the difficulty of laparoscopic operation,shortens the operation time and avoids the thoracotomy.

Objective To investigate the clinical and imaging features of cerebral cortical vein thrombosis (CoVT). Methods The clinical data of 13 inpatients with CoVT were enroled from September 2010 to September 2015. The etiology, clinical symptoms, imaging features, and differential diagnosis of CoVT w ere summarized and analyzed. Results Among the patients, there w ere 7 females (53.85%) and 6 males (46.15%). Their age ranged from 18 to 59 years (mean 34.23 ±12.08). The most common clinical manifestations were headache (9 patients) and seizures (9 patients). The 13 patients had cerebral parenchymal involvement and they al received anticoagulant therapy. Conclusions The clinical symptoms of CoVT are various. Seizures and headache are the most common symptoms. Most of patients are accompanied by brain parenchymal lesions and venous sinus thrombosis. When patients have headache and seizures, and head images suggest hemorrhagic infarction, imaging examination of the improvement of the cerebral venous system thrombosis is recommended.

Multidrug resistance is a common form of drug resistance of tumors and one main reason for chemotherapy′s failure and recrudescence of acute leukemia. In recent years,substantial studies addressed the different aspects about MDR1,including MDR1 genetic polymorphism,mRNA/protein expression as well as the function of its coding protein (P-gp).This paper reviewed recent advances about the relation between MDR1 genetic polymorphism and acute leukemia prognosis with the aim to improve acute leukemia curing and chemotherapy outcome evaluating in China.

0.05). CONCLUSION:The treatment of the Tile C type pelvic fracture with the percutaneous iliosacral articulation screws and pelvis external fixation under X-ray perspective has the advantages including small wound,simple operation,reliable fixation,short operation time,quick reactivating and low operation infection rate.

Objective To investigate the effect of sevoflurane postconditioning on the myocardial oxidative stress injury in patients undergoing heart valve replacement with cardiopulmonary bypass (CPB) . Methods Thirty ASA Ⅱ or Ⅲ and NYHA class Ⅱ or ID patients, aged 30-59 yr, weighing 42-62 kg, scheduled for cardiac valve replacement with CPB, were randomly divided into 2 groups ( n = 15 each) : control group (group C) and sevoflurane postconditioning group (group S) . Anesthesia was induced with iv injection of midazolam 0.05-0.08 mg/kg, fentanyl 3-6 μg/kg, vecuronium 0.10-0.15 mg/kg and etomidate 0.1-0.2 mg/kg. The patients were tracheal intu- bated and mechanically ventilated. Anesthesia was maintained with intermittent iv boluses of fentanyl and midazolam and continuous infusion of atracurium and propofol. In group S, 2% sevoflurane was given over 15 min via the cardiopulmonary bypass machine immediately after aortic unclamping. Blood samples from the internal jugular vein were collected immediately before skin incision (T1 ) and at 30 min, 3 h and 24 h after aortic unclamping (T2-4 ) for measurement of the plasma malondialdehyde level. Myocardial tissues were taken from the left auricle before operation and after termination of CPB for determination of α-glutathione-S-transferase expression by Western blot. Results The plasma malondialdehyde concentration was significantly lower at T2, 3, while a-glutathione-S-transferase expression in myocardial tissues higher after termination of CPB in group S than in group C ( P < 0.05) . Conclusion Sevoflurane postconditioning can enhance the antioxidant capacity and attenuate the myocardial oxidative stress injury in patients undergoing cardiac valve replacement with CPB, which may be helpful to reduce myocardial ischemia-reperfusion injury.

Objective To investigate the damage mechanism of fluetuant high glucose on the INS-1 cells (pancreatic β-cell lines).Methods The cells were divided into five groups:the control groups (A group:5.5 mmol/L of glucose),the continuing high glucose group (B group:16.7 mmoL/L of glucose),the fluctuant glucose group ( C group:16.7 mmol/L of glucose for cultivation for 2 h,then the concentration changed to 5.5 mmol/L for cultivation for 3 h,which was repeated 3 times per day;the ceils were kept in the medium containing 5.5 mmol/L of glucose during night time for 9 h),the continuing high glucose plus NAC ( 1.0 mmo/L) group ( D group),the fluctuant glucose plus NAC group ( E group).The intracellular reactive oxygen species (ROS) was observed by the flow cytometry.The activity of glucose-6-phosphate dehydrogenase (G6PD) was estimated by the tetrazolium linked cytochemical method.Results 72 h after intervention,the levels of ROSwere 37.77±2.31,86.97±7.97,124.27±10.04,60.92±2.61 and 51.47±3.36,respectively,in A~E group;the activities of G6PD were 1.25±0.03,1.09±0.02,1.03±0.01,1.12±0.02 and 1.21±0.01,respectively;the levels of NADPH were (0.123±0.003) mmol/mg prot,(0.112±0.004) mmoL/mg prot,(0.099±0.002 ) mmol/mg prot,( 0.116±0.005 ) mmol/mg prot and ( 0.120±0.002) mmol/mg prot,respectively.The level of ROS in the cells of the fluctuant glucose group were significantly higher than that in the continuing high glucose group ( P < 0.01 ).The G6PD activity and NADPH was significantly lower in fluctuant high glucose group than those in the continuing high glucose group (P <0.01 ).NAC co-cultivation decreased the extent of cell's change.Conclusions Exposure of INS-1 to high glucose lead to increased oxidative stress, possible mechanism included decreased G6PD activity and subsequent imbalance between oxidation and reduction.
