Risk factors for postoperative complications Clavien-Dindo classification≥gradeⅡ after lung cancer surgery / 中国胸心血管外科临床杂志

@#Objective     To investigate the risk factors for postoperative complications Clavien-Dindo classification≥grade Ⅱ after lung cancer surgery. Methods     The patients who underwent lung cancer surgery in a multicenter observational study from November 2017 to January 2020 were included. The Clavien-Dindo classification of postoperative complications was analyzed. Logistic regression was used to identify the risk factors for complications≥ gradeⅡ. Results     A total of 388 patients were enrolled, including 203 males and 185 females with a mean age of 56.14±10.36 years. The incidence of postoperative complications was 25.52% (99/388) after lung cancer surgery and the incidence of complications≥gradeⅡ was 20.10% (78/388). The five most common postoperative complications were pneumonia (6.96%), prolonged pulmonary air leak (>7 days, 5.67%), incision dehiscence (4.64%), arrhythmia (3.87%), and postoperative pleural effusion (3.35%). Multivariate analysis showed that open surgery [reference: uniportal thoracoscopic surgery, OR=2.18, 95%CI (1.01, 4.70), P=0.047], extended resection [reference: sublobar resection, OR=2.86, 95%CI (1.11, 7.19), P=0.030; reference: lobectomy, OR=2.20, 95%CI (1.10, 4.40), P=0.026] and operative time≥3 h [OR=2.07, 95%CI (1.12, 3.85), P=0.021] were independent risk factors for postoperative complications≥gradeⅡ after lung cancer surgery. Conclusion     Surgical approach, extent of resection and operative time are independent influencing factors for postoperative complications≥gradeⅡ after lung cancer surgery.

Preparation and identification of anti-TgAQP peptide antibody / 中国人兽共患病学报

In this study ,we intended to prepare anti‐Toxoplasma gondii aquaporin (TgAQP) peptide antibody which was used to the application in the detection of the aquaporin expression and its subcellular localization of Toxop lasma gondii (T .gondii) ME49 strain .The B cell peptide antigen was designed based on the TgAQP amino acids sequence .After the pep‐tide antigen was conjugated to the KLH ,the fusion antigen was injected into New Zealand rabbits to prepare polyclonal anti‐body ,followed by identification of ELISA ,Western‐blotting and immunofluorescence assays .The ELISA showed that the titer of anti‐TgAQP antibody was about 1∶40 000 .Western blotting revealed the specific affinity of the antigen to polyclonal anti‐body at 29 .9 kDa protein T .gondii .The protein detected by the indirect immunofluorescence assays was distributed in the cy‐toplasm of the parasite .Thus far ,the anti‐TgAQP polyclonal antibody was successfully prepared ,providing a useful tool for further study of biological function and metabolic characteristics of TgAQP .

Preparation and identification of rabbit polyclonal antibodies against vacuolar proton pyrophosphatase type I of Toxoplasma gondii / 南方医科大学学报

<p><b>OBJECTIVE</b>To prepare and characterize rabbit polyclonal antibodies against Toxoplasma gondii vacuolar proton pyrophosphatase type I (TgVP1).</p><p><b>METHODS AND RESULTS</b>Two synthesized peptides TgVP1-1 and TgVP1-2 as the haptens were conjugated with KLH to immunize rabbits. Indirect ELISA showed that the titers of rabbit anti-TgVP1-1 polyclonal antibody and rabbit anti-TgVP1-2 polyclonal antibody reached 1:128 000. Western blotting results revealed that both purified polyclonal antibodies could specifically bind to a purified 85 kD T. gondii protein predicted as TgVP1. The protein detected by these two polyclonal antibodies was distributed in the cytoplasm of T. gondii tachyzoite, and this distribution pattern was consistent with that of acidocalcisome.</p><p><b>CONCLUSION</b>The peptide-based method of antibody generation is efficient and the obtained TgVP1 polyclonal antibodies possess a high specificity to facilitate further study of T. gondii acidocalcisome and the diagnosis of toxoplasmosis.</p>

Standardization of Malignancies report in General Hospital promoted by combination of training and management / 中华医学科研管理杂志

Objective To explore appropriate management of cancer report for general hospital and analyze the effect.Methods Based on the requirements of cancer report for general hospital that formulated by the health administrative departments,we set the rule and process of malignancy report.We clear the responsibilities of reporting and the management,strengthen the training of malignancies report,make regular supervision and evaluation,and gradually use information live system to monitor malignancies report.Results In 2006-2010,the number of reports of malignancy in our general hospital has a upward trend.The false negative rate and delaying rate decreased year by year.The pass rate of the report card increased year by year,and the difference was statistically significant (＜0.05).With the increase of the rate of training for malignancies report,rate of timely report increased significantly.Conclusion General hospitals should use their own conditions to the development of scientific and operational report management systems and processes for malignancies.Attention should be paid to the combine of training and management and the gradual standardizing of the malignancies reporting.

The study of research ability of nurses in Peking university Shenzhen Hospital / 中华医学科研管理杂志

Objective The aim of this study was to determine the research ability,explore the reasons and point out the direction to improve the research ability of nurses in our hospital.Methods 375 cases of nurses in clinical work in our hospital were chosen with random sampling method to investigate the research ability.Results The variability of research ability score of nurses under investigation was comparatively large.The minimum of scores was 10,the maximum was 113 and the average score was 55.34±25.01.Various scores were all relatively low.The general trend is that the higher the academic and professional titles,the better the research ability.The various scores were independent of administrative rank.Conclusion General research ability of nurses in our hospital was relatively weak.It is necessary to train nurses in our hospital,especially those with lower academic and professional titles to improve the general research ability.

Study on performance assessment mode of clinical departments in modern hospital / 中华医学科研管理杂志

Objective Construct the reasonably effective performance assessment mode of clinical departments,which is suitable for the continuous development of modern hospital.Method Use of balanced scorecard (BSC) principle,using the analytic hierarchy process (AHP) and Rank sum ratio method (RSR)to establish a performance assessment system. Results Constructed the performance assessment mode of clinical departments,which can be dynamically adjusted based on management objectives strategy.The mode takes the BSC as the baseline,the strategy of hospital development as the guide,performance assessment index system as the key element. Conclusion The performance assessment mode of clinical departments,base on BSC,achieve the strategic performance management,and is conducive to the hospital for continuous improvement of medical care quality,in line with the long-term strategic needs of the hospital.

The Necessity and Feasibility for Doctors to Practice in Different Medical Institutions / 中国医学伦理学

With the economic development and the deepening of reform in China,more attention has been paid on health.Based on literature from Chinese Journal of Health Statistics in 2008,the number and ranks of practicing doctors,occupancy of hospital beds,the disease spectrums,outpatient per year were analyzed.The results hold it is better for the doctors to practice in more medical institutions.
