Background and purpose:Blood vessel metastasis often occurs after the operation of rectal cancer of stage Ⅱ and Ⅲ,angiogenesis is an important step of the procedure.Cycloxygenase-2(COX-2) and vascular endothelial growth factor(VEGF-C) are correlated to angiogenesis. The purpose of this study is to investigate the expressions of Cycloxygenase 2(COX-2) and vascular endothelial growth factor(VEGF-C) in rectal cancer of stage Ⅱ and Ⅲ,to explore the relationships between them and the tumor biological characteristics,tumor angiogenesis.Methods:The expressions of COX-2,VEGF-C and the microvessel density(MVD) were detected by immunohistochemical staining.Results:①The positive rates of COX-2 and VEGF-C expression in rectal cancer were 72.5%,higher than those in peritumoral normal tissue(P

OBJECTIVE: To evaluate the curative effect and costs of sequential therapy with cefuroxime for lower respiratory bacterial infection.METHODS: A total of 180 patients with lower respiratory bacterial infection were randomly divided into 3 groups: persistent intravenous drip group,sequential therapy group,and per os group.The therapeutic effects and the adverse drug reactions of the three groups were observed,and the data were subjected to cost-effective analysis in pharmacoeconomics.RESULTS: In persistent intravenous drip group,sequential therapy group,and per os group,the costs were(1 673.00?183.85),(1 268.10?112.25) and(994.80?102.65) yuan,respectively, the clinical effective rates were 93.33%,89.66%,and 69.35%,respectively,the cost-effectiveness were 1 792.56?196.97,1 414.34?125.20,and 1 434.46?109.79,respectively,and the incremental cost-effective ratios were in the intravenous drip group and sequential therapy group were 2 828.19?338.62 and 1 345.64?47.27,respectively as against per os group.CONCLUSION: Among the schemes,sequential therapy is the optimal one.

Objective To study the relationship between Lidocaine blood drug level and the cause of death from Lidocaine anaphylactic shock. Method Comparing and analyzing the blood drug levels by HPLC between two groups of people whose various indexes are normal before the surgery. Group 1 included 8 cases who accepted Lidocaine as anesthetic and died from Lidocaine anaphylactic shock. Group 2 included 11 cases who also took Lidocaine as anesthetic and passed the surgery smoothly. Results Lidocaine blood level of Group 1 (1.61?0. 45mg/L) is lower than that of Group 2 (2. 44 ?0. 47mg/L). Conclusion Lidocaine blood drug level has nothing to do with the cause of Lidocaine anaphylactic shock.

In this paper, the specific male sequeuce in paraffin section of various tissues with autolys is ofdifferent degrees was detected by polymerase chain reaction(PCR).The results shewed that PCR could be used for identifying sex in the tissues with low degrees ofautolysis; its positive rate was lower in high degrees with disappearance of nuclaic member and cell ou-tline,and often gave false negative results when the autolysis degree was high.

CONCLUSION:The structure for the use of narcotic analgesics in our hospital tends to be reasonable,which is basically in line with the Guiding Principle of Pain Relief Ladder for Cancer Pain.

Objective To evaluate the clinical efficacy and safety of immunosuppression of calcineurin inhibitor monotherapy (AiCNIm)after alemtuzumab induction following renal transplantation.Methods Randomized control clinical trials related to application of AiCNIm (AiCNIm group ) and conventional triple regimes (Triple group ) for immunosupression after renal transplantation,published from 1 980 to December 31 201 4,were searched online from PubMed,Embase,Web of Science,Cochrance library and China National Knowledge Infrastructure (CNKI) databases.Meta-analysis was performed by Rev Man 5.2 software.Results Five randomized control studies consisting of 421 renal transplant recipients were included.The results of follow up for 6-1 2 months revealed that compared with the Triple group, the incidence of rejection response confirmed by acute rejection or aspiration biopsy in the AiCNIm group was significantly lower [relative risk (RR) =0.59,95% confidence interval (CI):0.40-0.89 ].However,there was no significant difference in the risk of renal allograft dysfunction (RR =0.85,95%CI:0.38-1 .87),death of recipient (RR =0.89,95%CI:0.30-2.67),infection (RR =1 .03,95%CI:0.91 -1 .1 7)and new-onset diabetes after transplantation (RR =0.62, 95%CI:0.29-1 .30)between two groups (all in P >0.05).Conclusions According to the existing evidence,application of calcineurin inhibitor monotherapy after renal transplantation exerts short-term immunosuppressive effect and high safety after alemtuzumab induction.

Objective: To report on the two years outcome of Chinese multi-center study of the treatment of high risk non-calcified pure aortic regurgitation with transcatheter heart valve replacement (TAVR) using domestic made J-Valve™ system. Methods: The national multi-center clinical study of the treatment of high risk non-calcified pure aortic regurgitation with transcatheter heart valve replacement using domestic made J-Valve™ system was conducted during the period from April 2014 to July 2015. The follow-up time was up to 2 years. Forty-three cases with predominant aortic valve regurgitation were enrolled for transapical implantation of the J-Valve™ system from 3 Chinese centers, including 16 patients from Zhongshan Hospital, Fudan University, 23 patients from West China Hospital, Sichuan University, and 4 patients from Fuwai Cardiovascular Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College. There were 30 males and 13 females in this cohort. The age of the patients was (74±6) years (range: 61 to 84 years). The patiens were all sympotmatic preoperatively. All patients were considered at prohibitive or high risk for surgical valve replacement (Logistic European System for Cardiac Operative Risk Evaluation of (25.5±5.3)%, range: 20.0% to 44.4%) after evaluation by an interdisciplinary heart team. Comprehensive clinical and echocardiographic assessments were scheduled before discharge and at 30 days, 12 months, and 24 months after the procedure. Results: One patients was converted to surgical aortic valve replacement (SAVR) due to valve embolism into the arch. The other 42 cases had J-Valve™ systems implanted successfully. One patient died from multi-organ disorder due to paravalvular leak (PVL) during perioperative period. There was no acute myocardial infarction, stroke or coronary obstruction during the perioperative period. The median follow-up time was 725 days (range: 6 to 1 082 days). There were 5 patients died during the 2 years, follow-up, 2 patients had stroke, 2 patients had permanent pacemaker implanted. Three patients had valve related reinterventions: One for intraoperative valve embolism into the aortic arch followed by a conversion to SAVR which was mentioned above. One patient underwent SAVR on the postoperative day 6 due to moderate PVL and ventricular dysfunction. One patient underwent SAVR 6 months after primary procedure due to prosthesis thrombosis and severe aortic valve stenosis.Thirty-six patients with J-valve™ implanted survived to the latest echocardiogram follow-up, 25 patients had trivial or less PVL, 9 patients had mild PVL, and the transvalvular gradient after valve implantation was favorable at (9.8±5.8) mmHg (1 mmHg=0.133 kPa). Conclusions Transapical implantation of domestic made J-Valve™ transcatheter heart valve system for patients with predominant aortic regurgitation has a excellent early outcome. This novel technology is safe and effective.

Objective To survey the situation and related factors of maintenance medication treatment in schizophrenic patients re-hospitalized for relapse. Methods 362 patients re-admitted with schizophrenia and their relatives were interviewed with questionnaire which included 16 factors that might affect maintenance medication treatment. Results 63.8% patients stopped medication and 21.1% patients were on low-dose maintenance medication treatment by themselves, while 7.7% patients were on reasonable dose anti-psychotics in 2 years. The time of maintenance medication treatment related with insight (OR=2.2144, P=0.001), family care (OR=4.8842, P=0.025), outcomes of treatment (OR=2.2056, P=0.007) and negative life events (OR=0.4529, P=0.003). Conclusion Schizophrenic patients re-admitted with relapse often withdraw or reduce their medication by themselves, which risked with poor insight, poor therapeutic effect, poor care from their family, and more negative life events
