Objective　To study the diagnostic value of pleural fluid telomerase activity in distinguishing a malignant from a benign pleural effusion. Methods　Using a PCR-based assay, telomerase activity was examined in the pleural fluid cells obstained from 69 patients with pleural effusions (37 malignant, 32 benign). Results were compared with cytologic evaluation and carcinoembryonic antigen (CEA). Results　Of the 37 malignant specimens，26（70.27%）contained detectable telomerase activity. The positive rate in malignant pleural effusions was significantly higher than that in benign origin (2/32). Detection of telomerase in effusions was more sensitive than CEA level evaluation for the identification of pleural malignancy (telomerase assay: sensitivity=70.27%, specificity=93.75%; CEA: sensitivity=51.35%, specificity=96.87%). The consistant rate of telomerase with cytology was 54.05%. Conclusion　The detection of telomerase activity may be a useful adjunct to cytopathologic methods in the diagnosis of malignant pleural effusions. It may be useful in differential diagnosis of benign and malignant pleural effusions.

Objective To observe the efficacy and safety of pleural perfusion of recombinant human endostain ( endostar) combined with cisplatin ( DDP) in lung cancer patients with pleural effusion.Methods 80 patients with pleural effusion of lung cancer from January 2011 to December 2014 in our hospital were selected and randomly divided into the treatment group and the control group two groups with 40 cases in each group.Recombinant human endostain and DDP were injected into pleural cavity in the treatment group, the same dose of DDP was injected into the control group.Pleural effusion, KPS, Toxic and the exepress of vascular endothelial growth factor ( VEGF) of pleural effusion were measured before and after treatment. Results After treatment, the clinical efficacy of the observation group (RR), quality of life improvement rate and the level of VEGF in pleural effusion was significantly higher than that in the control group, the difference was statistically significant (P <0.05).The level of VEGF in Bloody pleural effusion was higher than in the non-bloody pleural effusion in the treatment group, there was significant difference (P<0.05).The observation group was higher than that of non hemorrhagic pleural effusion VEGF , the difference was statistically significant ( P <0.05 ) , both of them could lead to the decrease of VEGF level after treatmen, but there was no statistical significance between the two groups.Conclusion Clinical efficacy of intrapleural injection of recombinant human endostatin combined with cisplatin in patients with lung cancer complicated with pleural effusion, low adverse reaction, it is speculated that the recombinant human endostatin can inhibit the growth of tumor and the formation of pleural effusion by inhibiting the expression of VEGF in combination with cisplatin, it could effectively improve the quality of life of patients and prolong life.

Methods According to the admission date,the first 87 patients hospitalized in our department were assigned into the control group and another 84 into the intervention group.Then the human resources were divided based on the ABCD nursing classification and marking management for ICU.The two groups were compared in terms of adverse events.Results The incidences of pressure sores, non-planned extubation,improper clinostatism for using respirator,hypoglucycaemia during reinforced treatment with insulin, respirator-associated pulmonary pneumonia,tube-associated infection,and multidrug resistant bacteria in the intervention group were all significantly lower than those in the control group (allP<0.05).Conclusion The nursing classification and marking management for ICU nursing management can enhance the nursing quality.

Objective To study the shift handover experience of ICU clinical nurses. Method About 19 ICU nurses were enrolled in the investigation using semi-structured interviews and the results were analyzed with phenomenological analysis. Result Their shift handover experience were summarized into 6 themes, that is high recognition on the importance of shift handover, lack of standardized processes, incomplete contents of shift handover, frequent interruption, forgotten information and repeated information. Conclusions Shift handover is an important part of ICU nursing function but there are many problems in the practical operation. The nurse managers need to standard the handover process, stipulate handover contents and enhance the training on shift handover with specialist examination and positive results for the purpose of improving the quality of the shift handover.

Objective:To analyze deceleration capacity of heart rate (DC) in patients with ventricular arrhythmia , and explore its predictive value for ventricular arrhythmia .Methods :Dynamic electrocardiogram (DCG) data of outpatients and inpatients ,who were treated in our hospital from Jan 2012 to Jul 2015 ,were retrospectively ana‐lyzed .A total of 41 rehabilitation patients with ventricular tachycardia (VT) directly detected by DCG were treated as VT group ,another 37 cases with similar general data and non‐tachycardia were enrolled as non‐tachycardia group in the same period .DCG was used to measure and calculate DC in all subjects , DC indexes were compared between two groups .Results:DC<4.5 ms was regarded as abnormal and DC<2.5 ms was regarded as significantly abnor‐mal .Compared with non-tachycardia group ,DC significantly reduced [ (8.72 ± 1.78) ms vs .(4.01 ± 1.90) ms] , P<0.01 ;there were significant rise in abnormal DC rate (5.41% vs .51.22% ) and significant abnormal DC rate (0 vs .29.27% ) in VT group , P<0.01 both .Conclusion:Detection rate of abnormal DC is high in VT patients .DC measurement is helpful for predicting ventricular arrhythmia and sudden cardiac death .

Objective To investigate the effective methods for detecting the susceptibility of Staphylococcus aureus to Vancomycin. Methods An isolate of h-VRSA (heterogeneous Vancomycin-resistant Staphylococcus aureus) isolated from clinical specimen was inoculated on the increasing concentration of vancomycin agars. Varied degree of vancomycin of resistant S. aureus were obtained. The susceptibilities of these S. aureus to vancomycin were tested by agar screening test, broth microdilution method, E-test, disk diffusion method and automated methods. Results Agar screening test, broth microdilution method and E-test are effective for detection of vancomycin-intermediate S. aureus VISA, but disk diffusion and automated methods could not detect VISA. Conclusion Broth microdilution method and E-test are acceptable methods for susceptibility testing of S. aureus to vancomycin. The laboratories using automated methods and disk diffusion method as routine susceptibility test should consider adding a vancomycin agar screen plate to enhance detection of VRSA and VISA.

Objective:To detect genomic aberrations and investigate the expression and clinical significance of TBX2,CHK2, and p53 in malignant peripheral nerve sheath tumor (MPNST) tissues. Methods:We collected 63 cases of MPNST tissue samples, which were re-moved by resection and were confirmed by pathology, from January 1991 to December 2011 in Department of Bone and Sofer Tissue Tumor, Tianjin Medical University Cancer Institute and Hospital. Twelve fresh tumor samples with qualified DNA quality were selected from the above 63 cases of tissue samples. Genome abnormalities of 12 MPNST tissues were detected by next-generation sequencing. The protein expression levels of TBX2, CHK2, and p53 in 63 MPNST tissue samples were assessed by immunohistochemistry staining. Results:One case of TBX2 gene mutation was observed out of the 12 MPNST tissue samples. In 63 MPNST tissue samples, the protein expression rates of TBX2, CHK2, and p53 were 60.3%(38/63), 47.6%(30/63), and 30.2%(19/63), respectively. TBX2 expression was sig-nificantly correlated with AJCC (American Joint Committee on Cancer, AJCC) stage, recurrence, and metastasis (P<0.05). TBX2 expres-sion was directly correlated with that of CHK2 (r=0.254, P=0.045), and CHK2 expression was directly correlated with that of p53 (r=0.343, P=0.006). In terms of the disease-free survival and overall survival time, patients with high expression levels of TBX2, CHK2, and p53 had significantly worse prognosis than patients with low expression levels of TBX2, CHK2, and p53(all P<0.05). TBX2, CHK2, and p53 were independent prognostic factors of MPNST. Conclusion:TBX2 and its associated proteins may play important roles in MPNST development and progression. Detecting TBX2 expression may provide the theoretical basis for estimating the prognosis of patients with MPNST.
