ABSTRACT
【Objective:】 To construct the training index system of humanistic care for nursing students, and to provide reference for optimizing the educational model of humanistic care. 【Methods:】 Taking the quality care model as the theoretical framework, through the literature analysis, semi-structured interviews, and Delphi expert consultation, the nursing students’ humanistic care training index system was initially constructed, and the weights were determined by the analytic hierarchy process. 【Results:】 After two rounds of expert consultation, the expert authority coefficients were 0.89 and 0.91, the effective recovery rates of the questionnaires were 91.30% and 95.24%, respectively; the Kendall’s W values of expert correspondence were 0.179 and 0.118, respectively (P<0.05); The mean value of each index was 4.45~4.95, the coefficient of variation was 0.05~0.17, and the full score rate was 50%~95%. The humanistic care training index system for nursing students included 5 first-level indicators and 30 second-level indicators. 【Conclusion:】 Based on Delphi method and analytic hierarchy process, the training index system of humanistic care for nursing students has high enthusiasm, authority, concentration and coordination of experts, which is scientific, reliable and practical, and can provide reference for the development of caring education in colleges and universities.
ABSTRACT
<p><b>OBJECTIVE</b>To detect the presence of p15 antisense RNA(p15AS) in acute myeloid leukemia(AML).</p><p><b>METHODS</b>p15AS and p15 mRNA in two leukemia cell lines was detected with strand-specific primer RT-qPCR. To explore the connection between p15AS and AML, 43 patients with newly diagnosed AML and 21 patients with benign diseases (Iron deficiency anemia) as controls were enrolled. The expression level of p15AS in bone marrow cells derived from the patients and the controls were determined by strand-specific primer RT-qPCR, and its relationship with clinical features was analyzed.</p><p><b>RESULTS</b>The two AML lines displayed high p15AS and low p15 expression. Samples derived from the AML patients showed relatively increased expression of p15AS and down-regulated p15 expression in their bone cells. In contrast, the 21 controls showed high expression of p15 but relatively low expression of the p15AS. Compared with the normal controls, the expression levels of p15 protein were significantly lower among the AML patients (P<0.01). No relationships were detected between the level of p15AS and the patient's age, gender, FAB subtype, total white blood cell count, platelet count, proliferative degree of bone marrow cell and karyotype classification (P>0.05 for all comparisons).</p><p><b>CONCLUSION</b>High expression of p15 antisense RNA was frequently found among AML patients, and may play an important role in epigenetic silencing of p15.</p>

Objective To investigate the effects of trichostatin A (TSA) on Th1 and Th17 cells in the mice model of collagen induced arthritis (CIA).Methods Mice model of rheumatoid arthritis (RA) was induced in DBA/1 mice with type Ⅱ collagen.Paws were scored for histological severity of arthritis.The severity of inflammation of mice joints was evaluated by histological examination.Real time polymerase chain reaction (PCR) was used to determine mRNA of cytokines and transcriptional factors.Serum cytokine production was measured by enzyme linked immunosorbent assay (ELISA).T cell proliferation was examined by MTT method.One-way ANOVA and Student-Newman-Keuls were conducted in this study.Results The expressions of IFN-γand IL-17 mRNA of the CIA group were higher than that of the control group (8.27±0.64 vs 2.97±0.25,5.80±0.23 vs 0.70±0.26,all P＜0.01),but were inhibited significantly by TSA introduced at the onset of arthritis(6.60±0.52,2.50±0.41,all P＜0.01).Collagen specific T cell proliferation was significantly suppressed by the introduction of TSA.Increased level of IL-4 was observed in TSA treated group compared to that of CIA group(2.10±0.17 vs 1.01±0.08,P＜0.01).Conclusion Th1 and Th17 cells play crucial roles in the lesions of RA.TSA can suppress the progress of CIA by decreasing the percentage of Th1 and Th17.
ABSTRACT
AIM:To analyze circulating miR-141 in the serum as a non-invasive biomarker in the patients with prostate cancer ( PCa) and benign prostate hyperplasia ( BPH) , and healthy individuals.METHODS: A total of 75 pa-tients with PCa, 52 with BPH and 40 healthy individuals were enrolled into this study.Total RNA was isolated from the se-rum samples and the circulating levels of miR-141 were determined using quantitative real-time polymerase chain reaction. RESULTS:The serum levels of miR-141 were significantly higher in the patients with PCa compared to the patients with BPH and the healthy controls (P0.05).The serum miR-141 level was also found to be related to Gleason score, clinical stage and bone me-tastasis status of the patients with PCa (P0.05 for all comparisons).CONCLUSION: Circulating miR-141 could serve as a non-invasive biomarker for prostate cancer diagnosis, staging and prognosis prediction.
