Science is the power of improving the academic discipline in hospitals.Evaluation of research has always be the key issue for research management.Using stratification method to establish the evaluation system was constructed directly by high level research output and based on the process of scientific,which can conduct quantitative assessment for individual level.The contents included three parts:process indicators,basic achievement indicators and high level achievements indicators.The implementation effect was satisfied during last year.The evaluation system stimulates high level research output.

Objective To explore the value of IFN-γ produced or secreted by CD+4 T Lymphocytes from pleural effusion mononuclear cells for the diagnosis of tuberculous pleurisy(plTB).Methods The PEMCs of 40 patients with tuberculous pleural effusion and 30 patients with malignancy pleural effusion were selected as the tuberculosis and disease control groups, then co-cultured with the early secretory antigenic target 6 (ESAT-6) and culture filtered protein 10 (CFP-10) fusion protein (E/C).The numbers of spot forming cells(SFC) secreting IFN-γ were enumerated by ELISpot and the ratios of cells producing IFN-γ were detected by flow cytometry and intracellular cytokine staining.Moreover, the two indicators were compared between tuberculosis and disease control groups to evaluate the 2 methods detecting IFN-γ in the diagnosis of plTB.Results After E/C stimulation, the numbers of SFC were 205(125-450)SFC/5×104 PEMC in tuberculosis group and 5(2-18)SFC/5×104 PEMC in disease control group by ELISpot.The difference between two groups was statistically significant (U= 20.00, P<0.01).The proportion of IFN-γ-secreting CD+4 T lymphocytes was 3.27% (1.81%-7.34%) in tuberculosis group and 0.12% (0.06%-0.46%) in control group detected by FCM. The difference between the two groups was statistically significant (U=45.00, P<0.01).The indicators of ELISpot in detection of IFN-γ which was secreted by PEMC after co-cultured with E/C were as follows: sensitivity 92.5% (37/40), specificity 80.0% (24/30), positive predictive value 0.86, negative predictive value 0.89, positive likelihood ratio 4.63, negative likelihood ratio 0.09 and accuracy 87.1%;and for FCM, they were 87.5% (35/40), 90.0% (27/30), 0.92, 0.84, 8.75 and 0.14, respectively and accuracy 88.6%.Conclusion After E/C stimulation, the assay for IFN-γ-secreting CD+4 T lymphocytes by FCM and ELISpot is highly sensitive and specific for diagnosis of plTB as an auxiliary method.

stinguish active tuberculosis and healthy cases with tuberculosis exposure history according SFC count.

OBJECTIVE: The aim of this retrospective study was to analyze the recovery rate of sudden sensorineural hearing loss in children, and explore the prognostic factors in order to guide the clinical diagnosis and treatment. METHOD: A retrospective review was conducted for the prognosis of children with sudden sensorineural hearing loss during the past 5 years (from November 2010 to May 2015) in Chinese PLA General Hospital. This paper have a complete clinical data of 101 patients (113 ears)with sudden hearing loss, ranging from 0 to 18 years old Patients were divided into four groups according to hearing recovery and eight putative prognostic factors were analyzed. RESULT: Among 101 patients (113 ears), the ratio of male and female was 60:53. Treatment was initiated from 1 to 183 days after disease onset, with an average of (18.5 ± 22.1) d. Bilateral and unilateral hearing loss were 24 ears and 89 ears, respectively. The proportion of mild hearing loss, moderate hearing loss, severe hearing loss and profound hearing loss were 7.1%, 6.2%, 23.9% and 62.8%, respectively. Vertigo and tinnitus occurred in 54.9% and 77.9% of the patients, respectively. After the treatment, the complete recovery rate was 9.7% and the overall recovery rate was 36.3%. The degree of hearing loss, earlier treatment onset, sex and bilateral involvement were significantly associated with hearing recovery (P < 0.05). CONCLUSION Sudden sensorineural hearing loss in children was generally identified as severe and profound hearing loss, but after positive and timely treatment, it can be improved or even cured. The mild hearing loss, earlier treatment onset, unilateral hearing loss and female were positive prognostic factors. The concurrence of tinnitus or vertigo, the results of ABR and DPOAE had no significant influence on prognosis.

Objective To screen the specific cytokines of tuberculous pleural effusion(plTB)by using liquid array technique to establish a diagnostic model and discuss its application value.Methods A total of 86 patients with plTB(plTB group)were included,including 41 patients in the confirmed plTB group and 45 patients in the clinically diagnosed plTB group.There were 42 other patients with pleural effusion in the control group.Seventeen cytokines in pleural effusion were analyzed by liquid array technology.Interleukin(IL)-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-9,IL-10,gamma-interferon-induced protein 10(IP-10),IL-15,IL-17F,IL-27,tumor necrosis factor(TNF)-α,monocyte chemotactic protein-1(MCP-1),the expression levels of macrophage inflammatory protein-3a(MIP-3α),macrophage colony-stimulating factor(M-CSF)and β-interferon(IFN-β)were detected.Difference factors between the confirmed plTB group and the control group were screened,and the receiver operating characteristic(ROC)curve was drawn in the confirmed plTB patients.IP-10,IL-27 and MCP-1 with AUC>0.850 and specificity>80%were combined to diagnose plTB,and were compared with adenylate deaminase(ADA)and T-SPOT.TB in pleural effusion to evaluate the diagnostic efficacy.Results The levels of IL-2,IP-10,IL-27,TNF-α and MCP-1 were higher in the confirmed plTB group than those in the control group(P＜0.05).The sensitivity and specificity of IP-10,IL-27 and MCP-1 in the diagnosis of plTB were 87.8%and 81.0%.The sensitivity of three-factor combined diagnosis in 45 patients with plTB was still as high as 86.7%,and there was no significant difference in sensitivity compared with that in the diagnosed plTB group(P＞0.05).In the plTB group,the sensitivity of IP-10,IL-27 and MCP-1 combined detection was 87.2%,which was higher than that of T-SPOT.TB(81.4%)and ADA(54.7%).Conclusion The application of liquid array technology to the joint detection of pleural effusion IP-10,IL-27 and MCP-1 can provide help for the diagnosis of plTB.
