Objective To carry on the training of empathy ability among nursing undergraduates and understand its influence on that empathy and professional commitment. Methods Nursing undergraduates of two classes in the Chengdu University of TCM were selected as the objects in this study, who had accepted Nursing Psychology. The students in one class (52 cases) as the intervention group, while the students in the other class (61 cases )as the control group. Routine education was used in the control group, the empathy education was used in the intervention group in addition. On the basis of the Jefferson Scale of Empathy (JSE) and Nursing professional commitment Scale a survey on empathy ability among nursing undergraduates and professional commitment had done for the investigation of its influence on those two sides. Results After the training, the general professional commitment scores in the intervention group was 85.89 ± 11.86, which was significant higher than 77.53 ± 11.93 in the control group (t=3.822,P < 0.01). The final scores of commitment and empathy had significant relation with their respective latitudes (P < 0.05 or <0.01). Conclusions The training of empathy ability among nursing undergraduates affects their empathy ability and professional commitment. And students’professional commitment can be improved through some targeted trainings.

BACKGROUND:Long-term use of corticosteroids (hereinafter referred to as hormone) after renal transplantation could obviously lead to adverse reactions. Immunosuppressive regimen with less and no hormone has been a hot focus in the study of renal transplantation al over the world. However, reduction or withdrawal of hormones has a certain risk. At present, there is no unified scheme. Because urine protein can be immediately detected after tubular injury, to monitor urine protein can find the renal dysfunction after transplantation in recipients undergoing renal transplantation, which can gain time for clinical therapy. OBJECTIVE:To discuss the influence of hormone (prednisone) removal on the occurrence of urine protein in recipients undergoing renal transplantation. METHODS:A total of 35 recipients undergoing renal transplantation after removal of prednisone received immunosuppressive regimen of cyclosporine A or tacrolimus+mycophenolate mofetil bivalent. Initial dose of prednisone was 30 mg/d, and then gradual y reduced by 5 mg per week, and withdrawn at 1 month after renal transplantation. There were 16 cases in cyclosporine A group and 19 cases in tacrolimus group. Urine protein was measured and quantified at 3, 6, 12 and 24 months after renal transplantation and 3, 6 and 12 months after addition of prednisone in both groups. Simultaneously, serum creatinine, fasting glucose, body mass increases, the rate of acute rejection, infection, patient/graft survival at 2 years after renal transplantation and urine protein at 24 hours before and after adding hormone were recorded. RESULTS AND CONCLUSION:For the two groups, urineα1-microglobulin started to rise after 6 months of removal of prednisone. Urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin ascended obviously at 12 months. Urinary protein was positive in five cases of cyclosporine A group and in three cases of tacrolimus group. At 24 months, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously. Urinary protein was positive in cyclosporine A group with 11 cases and in tacrolimus group with 10 cases. 24-hour urinary protein quantity was more than 1 g in every case. On this base, we made the patients to take more prednisone for 6 months, so urineα1-microglobulin and urinary microalbumin began to descend. Each group had one case of positive urinary protein turning to negative. Twelve months after the adjustment of the prednisone, urinary microalbumin, urinaryα1-microglobulin, and urinary transferrin descended respectively. Positive urinary protein turned into negative:in cyclosporine A group with two cases and in tacrolimus group with three cases. 24-hour urinary protein quantity was around 0.7 g. Two years after renal transplantation, serum creatinine and acute rejection rates were higher in the cyclosporine A group than in the tacrolimus group (P<0.05). No significant difference in fasting glucose, body mass increase, infections, and patient/graft survival was detectable between both groups. Results suggested that removal of prednisone greatly affected urine protein in recipients undergoing renal transplantation. In particular, at 2 years after renal transplantation, urinary microalbumin, urinaryα1-microglobulin, urinary transferrin and urinary IgG ascended obviously, and the security needs further research.

Objective To better understand students' professional perception,humanistic education status quo and their preference to different humanistic education methods.Methods Questionnaire was conducted for 990 undergraduate students (2006 grade- 2010 grade) at medical school of Shanghai Jiao Tong university.SPSS 17.0 statistical software was used to analyze results of the questionnaire.Results Nearly 45％ students chose to major in clinical medicine out of personal interest.The identification of students for humanistic quality was lower than that for clinical knowledge and skills.More than 50％ students believed doctors were with high humanistic quality and there was a gap between students′ action and their understanding of the medical career identity and medical humanistic cultivation.More than 50％ students preferred activities that train medical and auxiliary skills.Nearly 67％ students also showed a shallow reading habit from regular internet surfing.Conclusion The professional perception of medical students are influenced by both social and historical factors influence.The gap between understanding and action is a consequence of current humanistic educational system.The humanistic educational methodology should conform to the psychological and s~ial characteristics of contemporary students.

Objective To observe the efficacy and adverse reaction of raltitrexed combined with irino-tecan as first-line chemotherapy for recurrent or metastatic gastric cancer.Methods From January 201 4 to March 201 5,39 patients of recurrent or metastatic gastric cancer who received treatment in the First People′s Hospital of Zhangjiagang of Jiangsu Province were collected.All patients received raltitrexed (3.0 mg/m2 , 1 5 min intravenous drip)on the first day and irinotecan (1 80.0 mg/m2 ,90 min intravenous drip)on the first day.One cycle lasted 21 days.The efficacies were evaluated every 2-cycle.Adverse reactions were evaluated every cycle.Results The efficacies and adverse reactions could be evaluated in 39 patients.The study received 0 complete remission,1 6 partial remission,1 1 stable disease,1 2 progression disease.The objective response rate was 41 .03% (1 6 /39).The disease control rate was 69.23% (27 /39).The median overall sur-vival time was 9.3 months (95%CI:8.8-1 1 .1 months).The median progression-free survival time was 6.0 months (95%CI:5.1 -6.8 months).The adverse reactions were mainly neutropenia,anemia,liver dysfunc-tion,the incidence of them were 35.90%,33.33% and 28.21 % respectively.Conlusion Raltitrexed com-bined with irinotecan as first-line chemotherapy for recurrent or metastatic gastric cancer acquires an definite efficacy,and the adverse reactions can be tolerated,which is worthy of further clinical research.

Objective To investigate the process of apoptosis in lungs and liver induced by crushing hindlimbs of rat, and study the mechanismof crush injury. Methods The rat experimental model of hindlimbs crush injury was established. The cell apoptosis in lungs and liver was detected by TUNEL assay, and the expression of Bax, Bcl-2 and caspase-3 apoptin was examined by immunohistochemistry. Results C ompared with the control group, the partial muscle injury of rat’s hindlimbs was more serious with more apoptosis observed in lungs and liver (P<0.05). The expression of Bax was up-regulated and Bcl-2 was down-regulated, whereas caspase-3 expression was activated (P<0.05). Conclusion The cell apoptosis has increased significantly in lungs and liver after crush injury of hindlimbs in rat. The corre-lation factor released during tissue injury may mediate apoptosis process.

AIM: To investigate the inhibitory effect of arsenic trioxide on human glioma cell line U251 growth, change of gene expression and intracellular calcium content. METHODS: MTT method was used to observe the growth inhibition effect. Cell cycle, positive rate of proliferation cell nuclear antigen (PCNA), apoptosis associated protein Fas and Bcl-2, and intracellular calcium ion (IECa~ 2+ ) levels were measured by flow cytometry in U251 cells treated with different doses of As_2O_3. Apoptosis was detected with annexin V-FITC+PI dual parameter. RESULTS: As_2O_3 inhibited the growth of U251 cells dramatically. There were obvious dosage-effect and time-effect correlations (P0.05). The cell cycle was arrested in G_2M phase. Apoptosis occurred in U251 cells treated with As_2O_3 by annexin V-FITC+PI dual parameter detection. CONCLUSION: As_2O_3 inhibits the growth of U251 cells in vitro dramatically and induces apoptosis. The mechanism is probably associated with the improvement of Fas expression and IECa~ 2+ levels, decrease in PCNA protein expression and cell cycle arrest.

AIM:To investigate the regulatory role of hypoxia mimic reagent cobalt chloride ( CoCl2 ) on cave-olin-1 (Cav-1) generation and the influence of Cav-1 on the abilities of migration and invasion of human lung adenocarcino-ma A549 cells.METHODS:The concentrations of Cav-1 and hypoxia-inducible factor ( HIF)-1αin pleural effusion of the patients with lung cancer ( MPE) or tuberculous pleurisy ( TBPE) were detected, and the correlation was also compared. A549 cells were treated with CoCl2 at different concentrations and time in the presence or absence of HIF-1αinhibitor YC-1.The concentrations of Cav-1 and HIF-1αin the cell supernatants were measured by ELISA.The effects of Cav-1 induced by CoCl2 on the migration and invasion of A549 cells were determined by scratch test and Transwell invasion trial, respec-tively.RESULTS:The levels of Cav-1 and HIF-1αin MPE were significantly higher than those in TBPE.There was a highly positive correlation between Cav-1 and HIF-1αlevels in the pleural effusion.CoCl2 induced the generation of Cav-1 and HIF-1αin A549 cells in a concentration-and time-dependent manner, the peak occurred at 200 μmol/L or 24 h, while the concentration over 200 μmol/L or after treated over 24 h, a concentration-or time-dependent inhibition was ob-served.HIF-1αinhibitor YC-1 concentration-dependently inhibited the generation of HIF-1αand Cav-1 induced by CoCl2 in A549 cells.CoCl2 enhanced A549 cells migration and invasion, with 200 μmol/L played the strongest role, which were down-regulated significantly in the presence of YC-1.CONCLUSION:The alteration of hypoxia-induced Cav-1 generation might be involved in the migration and invasion of A549 cells.A possible role for HIF-1αis indicated in Cav-1 generation.

Purpose To evaluate the diagnostic values of Clusterin, CXCL13, Podoplanin (D2-40), CD21 and CD35 in follcular den-dritic cell sarcoma. Methods The expression levels of 10 cases of follcular dendritic cell sarcoma ( FDCS) and 12 types of FDCS mimics (83 cases in total) were investigated by immunohistochemical methods, the latter including solitary fibrous tumor, leiomyosar-coma, gastrointestinal stromal tumor and others. The diagnostic validities of the five biomarkers were compared. Results ( 1 ) The positive rates of Clusterin, CXCL13, D2-40, CD21 and CD35 in the FDCS group were 100%, 70%, 60%, 90% and 80%, respec-tively, the corresponding rates in the control group were 30%, 4%, 11%, 2% and 0 in turn. (2) The five biomarkers could be cate-gorized into 3 groups, according to their diagnostic values in FDCS. The first group included CD21 and CD35, which had much higher sensitivities (90%, 80%), specificities (100%, 98%) and accuracies (98%, 96%), compared with the other biomarkers. The second group included CXCL13 and D2-40, which had a relatively lower sensitivities (70%, 60%), specificities (96%, 89%) and accuracies (94%, 86%), compared with CD21 and CD35. The third group included Clusterin, which had the highest sensitivity (100%), while the specificity (70%)and accuracy (73%) were inferior to the first and second groups. (3) The diagnostic values of CD21 and CD35 combination were 100%, 98%, 98%, 83% and 100%, respectively. Conclusions (1) CD21 and CD35 are the most valuable biomarkers for FDCS. The combined diagnostic effect of the two markers is generally superior to that of single marker. (2) Clusterin has the highest sensitivity for FDCS. However, the frequent expression in FDCS mimickers restricts its diagnostic values for FDCS. (3) CXCL13 and D2-40 may be used as a marker for FDCS, but are not recommended as the first selection based on their diagnostic performance. (4) On the reasons that FDCS mimickers may not uncommonly express Clusterin and D2-40, and rarely show positivity for CD21 or CXCL13, more attention should be paid to the phenomenon to avoid misdiagnosis.
