Objective To investigate the clinical outcome before and immediately after implementation of fast track surgery protocol on patients with gastric cancer.Methods One hundred and thirty patients with gastric cancer in our hospital underwent an elective,uncomplicated,open gastric surgery before (Traditional care group,n =65) and immediately after implementing fast track surgery (Fast track surgery group,n =65).Postoperative food and fluid intake,mobilization,length of hospital stay,and clinical outcome were recorded and analysed,and a interview-based assessment was performed on days 14 and 30 postoperatively.Results Patients implemented fast track surgery were associated with a significantly earlier resumption of mobilization and oral fluids and normal diet,shorter duration of intravenous infusion compared with traditional care patients 0.3 (0-1) d vs 3.3 (2-4) d,0.2(0-1) d vs 3.5(3-4) d,3.3(3-4) d vs 5.6(5-6) d,3.4(3-4) d vs 5.2(5-6) d; P=0.000,respectively.Postoperative hospital stay was also shorter in fast track surgery group 6.6 (6-8) d vs 8.6 (8-9) d ; P =0.000.Instrumental activities of daily living decreased in both groups on day 14,but significantly more in the traditional care group,despite having a higher preoperative instrumental activities of daily living level compared with the fast track surgery group 5.0 (3-6) vs 3.0 (3-5),4.0 (3-6) vs 3.0 (3-5) ; P =0.000,respectively.Preoperative fatigue score was not different between two groups,but the fatigue score was significantly increased on day 14,and returned to normal value on day 30 in the traditional care group 2.0 (1-5) vs 3.0 (1-5),2.0(1-5) vs 2.0(1-6) ; P =0.005,P =0.065.Total length of sleep on day 14 was increased significantly in the traditional care group,but not changed in the fast track surgery group compared with preoperative value 9.0 (6-11) vs 8.0(5-10) h,8.0(5-11) vs 8.0(6-10) h; P=0.000,P=0.327.Conclusions A fast track surgery protocol can lessen postoperative stress reactions and enhance recovery for patients with gastric cancer undergoing an elective,uncomplicated,open resection.

ObjectiveToevaluatelaparoscopiccholecystectomy(LC)versusopen cholecystectomy (OC) in compensated cirrhotics and model for end-stage liver disease (MELD) score and Child-Turcotte-Pugh (CTP)classification in predicting perioperative morbidity.MethodsBetween January 1998 and June 2011,128 cirrhotic patients of symptomatic innocuous gallbladder disease at CPT class A or B liver function were prospectively and randomly divided into LC group (64 patients) and OC group (64 patients ). Data were analyzed by T test, Mann-Whitney U test and Pearson x2 test.ResultsThere was no statistical differences in operation time between the two groups ( t =1.761,P =0.081 ).The intraoperative blood loss ＞ 200 ml occurred in 15 ( 26％ ) LC patients and 35 ( 55％ ) OC patients ( x2 =4.467,P =0.035 ).LC patients had earlier up and about,earlier oral intake,short hospital stay ( t =5.424,t =8.573,t =15.634; P =0.000,respectively) and lower complication rate [ CTP:24％ (14/58) vs 38％ (24/64),x2 =4.582,P =0.032; MELD scores 21％ (12/58) vs 34％ (22/64),x2 =4.238,P =0.040] compared with OC patients.LC patients' VAS- fatigue and VAS-pain scores on first 3 days were lower than OC according to the VAS (visual analogue scale) (Mann-Whitney U =473.0,MannWhitney =6.0,Mann-Whitney =22.5,Mann-Whitney =24.0,Mann-Whitney =46.0; P =0.000,respectively),and the VRS-cosmetic score was higher in LC group than in the OC group according to the VRS ( verbal rating scale) ( Mann-Whitney =145.0,P =0.000).MELD score ＞ 14 predicted higher blood loss and complication rate regardless of LC or OC,while CPT classification did not seem to predict intraoperative bleeding volume and morbidity.ConclusionsLC can be performed safely in cirrhotic patients with CPT class A and B.LC has less,blood loss lower postoperative complication rate,and quicker postoperative recovery.MELD score system is more valuable than CPT classification system in predicting blood loss and postoperative complication rate in cirrhotics undergoing cholecystectomy.

Objective To investigate the diagnostic value of intraductal ultrasonography for the quality of biliary stricture.Methods Data of the patients who had received operation because of biliary stricture after IDUS examination from 2006 to 2010 were collected.IDUS results were compared with those of operation.Results There were 43 cases of malignant strictures and 6 benign strictures in total.The sensitivity,specificity,positive predictive value,negative predictive value and diagnostic accuracy of intraductal uhrasonography for the quality of biliary stricture were 97.7％ ( 42/43 ),83.3％ ( 5/6 ),97.7％ ( 42/43 ),83.3％ (5/6) and 95.9％ (47/49),respectively,which were significantly higher than conventional imaging like ultrasound B,CT and MRCP.Twenty one cases in 32 were diagnosed as malignant biliary stricture with cytological brushing,with the diagnostic accuracy of 65.6％.All cases had been diagnosed by IDUS.Conclusion Intraductal ultrasonography is of high diagnostic value for biliary stricture.However,cytological brushing based on IDUS is of limited diagnostic value for malignant biliary stricture.

Objective To investigate the clinical value of fetal echocardiography in prenatal diagnosis of complete vascular ring. Methods Ultrasound images of 6 cases with complete vascular ring were retrospectively analysed and summarized, all cases were confirmed by autopsy after termination of pregnancy. Results Right aortic arch and left ductus arteriosus formed U shaped comlete vascular ring coursing around the trachea in 5 cases, left aortic arch and right aortic arch formed O shaped complete vascular ring in 1 case on three-vessel trachea view. Color Dopple flow imaging aided in identifying various components of the vascular ring. Conclusions Fetal echocardiography is of great clinical value in prenatal diagnosis of complete vascular ring. Three-vessel trachea view is important for screening with particular attention to the relationship of the aortic and duct arches to the trachea.

Objective To investigate the early diagnosis and treatment of primary gastrointestinal malignant lymphoma( PGIML). Methods The clinical materials of 33 cases with PGIML from 1997 to 2005 were retrospectively studied. Results The diagnosis rate of gastroenteroscopy was 44. 4% . The most common immune phenotype was B-cell lineage (90. 9% ). Of the 33 PGIML patients, 30 were treated with operation, 2 with H. poli elimination and 1 gave up treatment. Among the operation cases and operation plus chemotherapy cases 19/21 cases (90. 5% )and 6/9 cases (66. 7% ) survived more than 2 years respectively, the other 6 cases died. Conclusion It is hard to diagnose PGIML in early stage. The effectiveness of surgery on treating PGIML should be further confirmed by profound prospective randomized trials.

The network platform was used for classroom teaching of ocular fundus disease in auxiliary , and the result showed it was helpful to breaking the time and space constraints in conventional teach-ing, expanding the teaching content, solving the difficulties in teaching, improving the students' learning initiative, and realizing the interactive teaching.

This paper was aimed to study the effectiveness and safety of TanshinoneⅡA Sulfonate Sodium Injection in the treatment of unstable angina pectoris (UAP). Keywords such as coronary atherosclerotic heart disease, coronary heart disease, unstable angina, chest impediment, cardialgia, TanshinoneⅡA Sulfonate Sodium Injection, tanshinone injection, tanshinoneⅡA sulfonate, unstable, angina, randomized controlled trial (RCT), and clinical trials were searched in CNKI, VIP, Wanfang and Pubmed from the construction of database until October 31st, 2014. The inclusion criteria were RCT with clinical data integrity, similar literature research methods, and good balance between groups. The Jadad score method was used to carry out quality assessment. Meta-analysis was conducted by RevMan5.2 software. Count data was processed by odds ratio (OR). Measurement data was processed with the weighted mean differences (WMD). The 95% confidence interval (CI) was also calculated. The heterogeneity test result of included literatures was P > 0.05. The fixed effects model was used in the meta-analysis. On the other hand, random effect model was used. For the analysis results of more than 10 papers, the funnel plot was used in the analysis of publication bias. The results showed that a total of 34 studies were included. The results of meta-analysis suggested that the total efficiency of conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP was [OR = 3.83, 95%CI (3.11, 4.71),P < 0.000 01]. The electrocardiogram improvement rate was [OR = 3.34, 95%CI (2.61,4.28),P < 0.000 01]; plasma viscosity improvement was [WMD = -0.20, 95%CI (-0.38, -0.03),P = 0.03]; high shear viscosity of whole blood improvement was [WMD = -0.67, 95%CI (-0.85, -0.50),P < 0.000 01]; C-reactive protein improvement was [WMD = -2.66, 95%CI (-3.31, -2.00),P < 0.000 01]. It was concluded that the conventional treatment plus TanshinoneⅡA Sulfonate Sodium Injection for UAP had certain clinical effect with no obvious adverse reaction. However, due to the poor quality of the existing research literatures, the results should be further verified by large amount of high quality RCTs.
