Objective To discuss the clinical application of medical coordination and hierarchical responsibility system in interventional nursing care which is carried out based on the “Henan Province Model”. Methods From November 2003 to April 2014 at authors’ hospital, medical coordination and hierarchical responsibility system was executed through setting up a ranking system of nursing position , optimizing shift process , dividing physician-nurse medical liability groups , strengthening medical training , implementing medical coordination service mode, etc. The clinical results were compared with those of conventional nursing care that were recorded during the period from May to Oct. of 2013. Results After implementation of medical coordination and hierarchical responsibility system, the quality of medical care, the patent’s satisfaction, the cooperation satisfaction of physicians and nurses were significantly improved. Compared with those before implementation of medical coordination and hierarchical responsibility system , the differences in the above indexes were statistically significant(P<0.01 or P<0.05). Conclusion Based on multidisciplinary joint diagnosis and treatment, and combined with coordination physician-nurse service mode, the enthusiasm of nursing staff can be motivated and the tacit understanding between physicians and nurses as well as the quality of nursing service can be improved. All of the above will promote the development of nursing discipline.

Objective To observe the protective effect of the traditional Chinese medicine prescription, Jiu Nao Yi Zhi water extract, on human neuroblastoma SH-SY5Y cell line, its effect on expression of insulin signal transduction pathway, and to explore the related mechanisms.Methods SH-SY5Y cells cultured in vitro, were divided into control group, Jiu Nao Yi Zhi No.1 prescription group and No.3 prescription group.The doses were 0.0625 mg/mL, 0.125 mg/mL, 0.25 mg/mL, 0.5 mg/mL and 1 mg/mL.The thiazolyl blue ( MTT) metabolic rate of each group was determined.The dose of 0.125 mg/mL was chosen for cell immunofluorescence analysis, and to observe the expression of insulin receptor substrates-1 ( IRS-1 ) , cAMP response element binding protein ( CREB ) , and the factors of insulin signal transduction pathway.Results Compared with the control group, MTT metabolic rates of the Jiu Nao Yi Zhi groups were significantly increased (P<0.05), and the cell morphology was much better in those groups, cell body more plump, well-adherent and neurite extensions were observed.The expressions of IRS-1 and CREB were higher than that in the control group.Conclusions The traditional Chinese medicine prescription Jiu Nao Yi Zhi water extract can protect neurons by promoting nerve cell growth, and improving the expression of IRS-1 and CREB, the factors of insulin signal transduction pathway.

5-20 wt% trimethoxysilylpropyl octadecyldimethyl ammonium chloride (QAS) was used to modify Poly (ε-caprolactone) (PCL)-gelatin hybrid to fabricate non-leaching antibacterial nanofiber membranes (PG-Q) by electrospinning. The results from scanning electron microscopy (SEM) and transmission electron microscopy (TEM) indicated that the QAS leaded to phase separation between the QAS and PCL. Hydrophilic test demonstrated that the PG-Q nanofiber membranes had hydrophobic surface, which was help for peeling off the dressing from the wound. Additionally, the physical and chemical cross-linking between the QAS/PCL and QAS/gelatin were confirmed by Fourier transform infrared (FTIR), which were good for long lasting antibacterial effect. The PG-Q membranes also showed excellent cell-biocompatibility. Furthermore, compared with pure PCL nanofiber membrane, the PG-Q nanofiber membranes, especially PG-Q15 (QAS: 15 wt%) and PG-Q20 (QAS: 20 wt%), showed a considerable increase in the bacteriostatic rate of and (more than 99% after 12 h). Therefore, electrospinning non-leaching antibacterial nanofiber membranes could be an optimal choice for antibacterial wound dressing.
