Objective To explore the effect of TBL based on evidence-based medicine PICOS model in practice teaching of neurology. Methods Totally 47 medical undergraduates in our department were chosen and randomly divided into 2 groups during March 2016 to April 2016. 24 students in the trial group were taught with TBL based on PICOS, while other 23 students in the control group were only taught with conventional TBL method. After three times clinical practices, the test referring to disease pathogenesis, clinical manifestations, auxiliary examinations, diagnosis and treatments of related diseases was performed, and meanwhile, questionnaires were distributed to students in order to survey their satisfaction degree of teaching methods. All the evaluation results and scores of two groups were compared. Statistical data were analyzed by using t-test or Chi-square test with SPSS 17.0 software. Results The score of the theoretical test of trial group was significantly superior to the control group [(89.08±3.60) vs. (79.09±7.75), t=5.707, P=0.03 ]. Survey showed that in the experimental group , the number of students in the trial group who thought teaching method could help understand clinical thinking of neurology and could help integrate the theory into clinical practicewas significantly higher than that in the control group (P<0.05). Conclusion In the clinical teaching of neurology, the TBL based on PICOS model is more effective than conventional TBL method for medical undergraduates.

OBJECTIVE: To discuss the scoring formula and evaluate the lists equivalence of Mandarin Quick Speech-in-Noise (M-Quick SIN) test materials in mainland China, and for standardizing our research. METHOD: Double 39 subjects with normal hearing were participated in part one and part two of our experiments, respectively. 20, 18, 15, 13, 10, 8, 5, 3, 0, -2, -5, -7, -10 dB SNR were presented in part one; and 20, 15, 10, 5, 0, -5 dB SNR were presented in part two. The results were analyzed by SPSS 13.0. RESULT: SNR-50 was -2.24 dB SNR and "SNR loss = 24.5--correct words" was defined as the scoring formula. All the 13 lists had the e quivalent difficulty. CONCLUSION Defined "SNR loss = 24.5--correct words" as the scoring formula of M-Quick SIN, and the 13 lists had better difficulty equivalence, which could be used in our further clinical research.

Objective To evaluate the test -retest reliability of sentence materials, and to standardize Man_darin Speech Test Materials (MSTMs). Methods Forty normal-hearing subjects aged from 18 to 30 years old were recruited in this study. The sentence materials were tested at 9 dB HL to these subjects according to the prepare ex_periment. The retest was carried out in the same condition after an interval of 14~28 days. The difference between test and retest score was examined by t-test, and the critical difference (CD) was analyzed with 95% confidence in_terval (CI). ResuIts There was no significant difference between the test and retest scores about speech perception performance. The critical difference was 18. 93% at 95% confidence interval, and the number of the corresponding key words was 10. ConcIusion The results showed that sentence materials of MSTMs have good test-retest relia_bility except list 6. The interventions could be considered effective just when the difference of the same subject's score exceed 18. 93%, that means 10 key words are necessary to improve that the intervention is effective.

OBJECTIVE: To analyze the short monosyllabic list of Mandarin speech test materials (MSTMs) which have been evaluated the equivalence of difficulty, and to establish the performance-intensity function (P-I function) for people with normal hearing as clinical reference of hearing recovery and individuals ability to perceive and process speech. METHOD: Thirty-seven subjects (the age ranged from 18 to 26 years old) who speak Mandarin well in their daily lives with normal hearing participated in this study. Eight lists of the Short Mandarin Monosyllabic materials (20 words per list) with equal difficulty were utilized. The results were analyzed by Statistical Package for the Social Sciences (SPSS) software version 17.0. RESULT: P-I function for short monosyllabic word list was x = 98.557/(1 + 12.243 exp (-0.17(P-15, x(max) = 98.557. And the sound pressure level of speech corresponding to a 50% recognition score was 29.6 dB SPL or 9.6 dB HL. The results showed P-I function of 3.1 per dB for Mandarin materials. CONCLUSION The study established the P-I function of the Mandarin short monosyllabic word list materials with equal difficulty, which provides the normative data for identifying the normal hearing in a clinical setting.

Objective:To investigate the effect and related mechanism of TRAP1 on the invasion and migration of human bladder cancer through TGF/Smad3 signal path.Methods: Selected from BIU-87 of high expression of TRAP1 in bladder cancer cell lines through Western blot techniques.TRAP1 knockdown lentivirus (LV3-TRAP1) was used to silence the expression of TRAP1.GFP fluorescene and PCR detector was used to detected the efficiency of gene silencing and the effectiveness of gene silencing;effect of TRAP1 on the invasion and migration ability of BIU-87 were detected by Transwell matrigel invasion assays and wound healing assays,CM-H2DCFDA fluorescent staining was used to deteced the cell ROS of BIU-87 with LV3-TRAP1.Detected the level of TGF/Smad3 signal protein by Western blot.Results: LV3-TRAP1 lentivirus could effectively inhibit the expression of TRAP1 compared with LV3-NC.LV3-TRAP1 lentivirus could effectively inhibit the cell RPS of BIU-87.Knockdown the expression of TRAP1 could inhibit the invasion and migration of BIU-87.Knockdown the expression of TRAP1 in BIU-87 could reduce the protein level of TGF/Smad3.Conclusion: Silencing TRAP1 could inhibit the invasion and migration of bladder cancer cell through TGF/Smad3 signal pathway.

This paper aims to retrospectively analyze the nursing management of one-stop hybrid procedures and to sum up the clinical experience.The key point of successful implementation of nursing management of one-stop hybrid procedures lies in the layout of hybrid operation room,in the intraoperative nursing cooperation and the professional nursing personnel training,and in the establishment of a new talent training mode that contains flexible allocation mechanism of nursing human resources as well as short-term post rotation of professional nursing staff.The one-stop hybrid operation is a minimally-invasive procedure for the treatment of complex diseases.Scientific nursing management is the strong guarantee to ensure a successful “one-stop” hybrid operation.

Objective To evaluate the clinical effects of long-term domiciliary oxygen therapy (LDOT)in accompany with pummonary rehabilization program on the patients with chronic obstructive pulmonary disease (COPD).Methods Seventy two COPD cases receiving LDOT treatment were randomized into treatment group and control group.The patients in control group were given LDOT alone,while the treatment group was given pulmonary rehabilization besides LDOT.Lung functions,arterial blood gas parameters and blood rheological parameters were compared between the two groups 2 years after the observation.Results The follow-up period lasted for 1 - 2 years.The frequency of acute exageration in the treatment group ( 3.0 ± 1.3 ) was significantly lower than that of control group (4.0 ± 1.6) ( t =1.893,P ＜ 0.05 ).Compared with that of control group,the FEV1([1.59±0.08]L vs.[1.41 ±0.13]L,t =-3.966,P ＜0.01),FVC ([2.47 ±0.20]L vs.[2.27 ±0.17]L,t=-2.788,P＜0.05),FEV1％ ([2.47±0.20]％ vs.[2.27±0.17]L,t=-4.402,P＜0.01) and PaO2 ( [79.1 ± 8.9 ] kPa vs.[ 60.0 ± 6.6 ] kPa,t =- 4.622,P ＜ 0.01 ) were significantly increased,while plasma viscosity ( [ 2.14 ± 0.31] mPa · s vs.[ 2.44 ± 0.45 ] mPa · s,t =1.985,P ＜ 0.05 ),Low shear blood viscosity ( [ 13.48 ± 1.97 ] mPa · s vs.[ 14.33 ± 1.87 ] mPa · s,t =2.126,P ＜ 0.05 ),median shear whole blood viscosity( [ 6.33 ± 0.66 ] mPa · s vs.(7.92 ± 0.98 ) mPa · s,t =4.238,P ＜ 0.01 ),high shear whole blood viscosity ([4.58 ±0.59] mPa · s vs.[5.33 ±0.68]mPa · s,t =0.3890,P ＜0.01) and erythrocyte sedimentation rate ( [ 30.63 ± 5.76 ] mm/1 h vs.[ 35.63 ± 6.925 ] mm/1 h,t =2.230,P ＜ 0.05 ) was greatly decrease.Conclusion Long-term domiciliary oxygen therapy in company with pulmonary rehabilization program is helpful to improve the lung function,arterial blood gas parameters and rheological status of COPD patients.
