Objective:To investigate the value of clinical nursing path teaching based on core competencies in the clinical teaching of urology nursing students.Methods:A total of 100 nursing students who received nursing internship in Department of Urology, China-Japan Union Hospital of Jilin University, were selected as subjects and were divided into observation group and control group using a random number table, with 50 students in each group. The students in the control group received traditional teaching, while those in the observation group received clinical nursing path teaching based on core competencies. After the end of teaching, the core competency evaluation form for nursing students was used to evaluate core competencies, and the self-learning ability evaluation tool for nursing students was used to evaluate self-learning ability. SPSS 22.0 software was used for t test. Results:Compared with the control group, the observation group had significantly higher scores of core competencies (operation skills, theoretical knowledge, self-development ability, clinical nursing ability, interpersonal communication ability, and critical thinking ability) ( P<0.05). The observation group had a significantly higher score of self-learning ability than the control group ( P<0.05). Conclusion:In the teaching of urology nursing students, the application of the clinical nursing path based on core competencies can significantly improve the core competencies of nursing interns and the quality of teaching.

Objective: Sweet Tea (ST), derived from the leaves of Lithocarpus polystachyus, is a Chinese folk medicine with wide pharmacological activities. However, the promotive effects of ST water extract on hepatocytes proliferation and its underlying mechanism remains still unknown. In the present study, the beneficial effects of ST water extract on human hepatocytes and its possible mechanism were investigated. Methods: MTT assay was used to detect the safety range of ST; HL7702 cells were divided into four groups: control group, ST low- (50 μg/mL), medium- (200 μg/mL) and high-concentration (800 μg/mL) groups; BrdU ELISA and EDU staining were used to observe DNA content and cell proliferation; Moreover, flow cytometry was applied to analyze the distribution of cell cycle. Furthermore, the expression of cyclin D1, CDK4, HGF/c-Met, Akt, Erk1/2 were detected by Western blot. Results: It was found that ST water extract concentration-dependent promoted human hepatocytes HL7702 cell proliferation within 72 h through accumulating the cells in S phase and G2/M phase. Furthermore, ST water extract up-regulated expression of Cyclin D1 and CDK4 proteins. Moreover, ST water extract not only increased HGF expression and phosphorylation of c-Met level, but also activated the phosphorylation levels of AKT, ERK1/2. Interestingly, both of AKT inhibitor A6730 and ERK1/2 inhibitor U0126 reversed the promotive effects of ST water extract, which further confirmed that activation of AKT and ERK1/2 were involved. Conclusion: The findings reveal that ST water extract promoted HL7702 cells proliferation through the stimulation of cell cycle mediated by activating the AKT- and ERK1/2-related pathway.

[Abstract] Objective: To observe the effects of shikonin on the proliferation, apoptosis and cell cycle of human esophageal carcinoma TE-1 cells, and to explore its mechanism. Methods: TE-1 cells were treated with different concentrations of shikonin (0, 1, 5, 10 µmol/L). MTT assay was used to detect cell proliferation at different time points (24, 48 and 72 h). After treatment with shikonin for 48 h, cell apoptosis in TE-1 cells of each group was observed with Hoechst 33258 fluorescence staining. Flow cytometry was used to detect apoptosis and cell cycle. The changes in expression of TRAP1/Akt/mTOR signaling pathway related proteins were detected by Western blotting. Results: Shikonin inhibited the proliferation of TE-1 cells in a time-dose-dependent manner (P<0.05 or P<0.01). Compared with the control group, shikonin significantly promoted the apoptosis of TE-1 cells (P<0.01), induced the G0/G1 phase block of TE-1 cells (P<0.05 or P<0.01), and reduced the expression levels of TRAP1, p-Akt and p-MTOR (P<0.05 or P<0.01). The above effects were all dose-dependent. Conclusion: Shikonin can significantly inhibit the proliferation of TE-1 cells in vitro, induce G0/G1 phase arrest and promote apoptosis, which may be closely related to the inhibition of TRAP1/Akt/mTOR signaling pathway.

C-fos is a transcription factor that plays an important role in cell proliferation, differentiation and tumor formation. The aim of this study was to clone the goat c-fos gene, clarify its biological characteristics, and further reveal its regulatory role in the differentiation of goat subcutaneous adipocytes. We cloned the c-fos gene from subcutaneous adipose tissue of Jianzhou big-eared goats by reverse transcription-polymerase chain reaction (RT-PCR) and analyzed its biological characteristics. Using real-time quantitative PCR (qPCR), we detected the expression of c-fos gene in the heart, liver, spleen, lung, kidney, subcutaneous fat, longissimus dorsi and subcutaneous adipocytes of goat upon induced differentiation for 0 h to 120 h. The goat overexpression vector pEGFP-c-fos was constructed and transfected into the subcutaneous preadipocytes for induced differentiation. The morphological changes of lipid droplet accumulation were observed by oil red O staining and bodipy staining. Furthermore, qPCR was used to test the relative mRNA level of the c-fos overexpression on adipogenic differentiation marker genes. The results showed that the cloned goat c-fos gene was 1 477 bp in length, in which the coding sequence was 1 143 bp, encoding a protein of 380 amino acids. Protein structure analysis showed that goat FOS protein has a basic leucine zipper structure, and subcellular localization prediction suggested that it was mainly distributed in the nucleus. The relative expression level of c-fos was higher in the subcutaneous adipose tissue of goats (P < 0.05), and the expression level of c-fos was significantly increased upon induced differentiation of subcutaneous preadipocyte for 48 h (P < 0.01). Overexpression of c-fos significantly inhibited the lipid droplets formation in goat subcutaneous adipocytes, significantly decreased the relative expression levels of the AP2 and C/EBPβ lipogenic marker genes (P < 0.01). Moreover, AP2 and C/EBPβ promoter are predicted to have multiple binding sites. In conclusion, the results indicated that c-fos gene was a negative regulatory factor of subcutaneous adipocyte differentiation in goats, and it might regulate the expression of AP2 and C/EBPβ gene expression.
