Objective:
To investigate the current status of nurses’ perceived professional benefits in 3A-level hospitals in Tianjin, and analyze its influencing factors.
Methods:
A total of 421 clinical nurses from five 3A-level hospitals in Tianjin were recruited for investigation on perceived professional benefits by Nurses’Perceived Professional Benefits Scale.
Results:
The total score of nurses’ perceived professional benefit was 110.50±14.24, the score index was 77.34%. Among five dimensions, the highest scores index was 84.80% for personal development, the lowest was 71.57% for identification by relatives and friends. Multiple linear regression analysis showed the three variables, such as department, teaching and cooperative relation between doctors and nurses entered the model, higher perceived professional benefits was observed in medical nurses, teaching nurses, and those with better cooperative relation between doctors and nurses (

PURPOSE: Several studies have shown that the oral cavity is a secondary location for Helicobacter pylori colonization and that H. pylori is associated with the severity of periodontitis. This study investigated whether H. pylori had an effect on the periodontium. We established an invasion model of a standard strain of H. pylori in human periodontal ligament fibroblasts (hPDLFs), and evaluated the effects of H. pylori on cell proliferation and cell cycle progression. METHODS: Different concentrations of H. pylori were used to infect hPDLFs, with 6 hours of co-culture. The multiplicity of infection in the low- and high-concentration groups was 10:1 and 100:1, respectively. The Cell Counting Kit-8 method and Ki-67 immunofluorescence were used to detect cell proliferation. Flow cytometry, quantitative real-time polymerase chain reaction, and western blots were used to detect cell cycle progression. In the high-concentration group, the invasion of H. pylori was observed by transmission electron microscopy. RESULTS: It was found that H. pylori invaded the fibroblasts, with cytoplasmic localization. Analyses of cell proliferation and flow cytometry showed that H. pylori inhibited the proliferation of periodontal fibroblasts by causing G2 phase arrest. The inhibition of proliferation and G2 phase arrest were more obvious in the high-concentration group. In the low-concentration group, the G2 phase regulatory factors cyclin dependent kinase 1 (CDK1) and cell division cycle 25C (Cdc25C) were upregulated, while cyclin B1 was inhibited. However, in the high-concentration group, cyclin B1 was upregulated and CDK1 was inhibited. Furthermore, the deactivated states of tyrosine phosphorylation of CDK1 (CDK1-Y15) and serine phosphorylation of Cdc25C (Cdc25C-S216) were upregulated after H. pylori infection. CONCLUSIONS: In our model, H. pylori inhibited the proliferation of hPDLFs and exerted an invasive effect, causing G2 phase arrest via the Cdc25C/CDK1/cyclin B1 signaling cascade. Its inhibitory effect on proliferation was stronger in the high-concentration group.

Objective:
To investigate effects of personal innovation behaviors, self-efficacy and colleague solidarity of nurses on career success, and to provide the basis for career planning and management of clinical nurses.
Methods:
A total of 441 registered nurses from eight grade three and first-class hospitals in Tianjin were measured with personal innovation behaviors scale, self-efficacy scale, colleague solidarity of nurses' scale and career success scale.
Results:
The total score of personal innovation behavior was (21.58±4.81). The total score of self-efficacy was (27.68±6.53). The total score of colleague solidarity of nurses was (95.12±9.42). The total score of career success was (35.75±9.27). The personal innovation behaviors, self-efficacy, colleague solidarity of nurses career success and each dimension showed positive correlation(
