Objective To study the effects of the clinical pathway on hip arthroplasty. Methods Fifty patients with hip arthroplasty were selected. Twenty-three cases in the control group were treated with traditional methods, and 27 cases in the experimental group were applied with the clinical pathway for standardized treatment. Any differences in Harris scores, hospital costs and days in postoperative care at 1 week and 3 months were compared statistically between the two groups. Results Complications, hospital costs and average length of stay in postoperative care were significantly lower in the experimental group than among the controls. The Harris scores in postoperative week 1 were significantly higher in the experimental group than among the controls. Conclusion The clinical pathway using standard diagnosis and treatment can not only decrease hospital costs and average length of stay, it can also limit postoperative complications and quickly improve joint function, giving better quality medical care.

The performance evaluation is an effective method to guide the public hospitals behavior and pro-mote their sustainable development.The introduction of disease severity could make the performance evaluation sys-tem more scientific and reasonable, and encourage the hospitals to improve their technical skills and services ability. Based on the Shanghai diagnosis related groups system, a case-mix index ( CMI) was introduced and a severity score of disease was developed after the relative weight ( RW) adjustment to evaluate different types of disease severity in hospitals.The results have shown that CMI effectively reflects the patients'disease severity and the intensity of treat-ment in those hospitals taken into consideration.Therefore, the scientific indicators should be selected and the evalu-ation system should be improved thereby establishing an effective monitoring and dynamic adjustment mechanism and further developing the diagnosis related group application.

Objective To construct,express,purify and identify the gene encodi ng major outer membrane protein of Neisseria gonorrhoeae (Porin I, or PI). Metho ds The gene encoding for PI of N.gonorrhoeae was amplified by PCR and cloned int o expression plasmid pGEX-4T-2 to form pGEX-4T-2/PI recombinants. A high lev el expression of GST-PI fusion protein was obtained in GST gene fusion system (GST:glutathione S transferase). The analysis indicated that the expressed pr otein was present predominantly in the insoluble form. Therefore, the induced pr otein was purified by SDS-PAGE, and bands corresponding to polypeptides of GST-PI fusion protein were excised and subjected to electroelution. A dot immunoch romatographic assay was employed to demonstrate whether the purified protein was gonococcal PI specific. Results The pGEX-4T-2/PI expression recombinants were constructed,expressed,purified and identified successfully. SDS-PAGE analysis and dot immunochromatographic assay suggested that the recombinant GST-PI fusio n protein was a 60 000 molecular weight protein andidentical in size to native PI and reacted with anti-PI monoclonal antibody. Conclusion Our results may lead to a potentiality for further study of diagnosti c kits and vaccine for Neisseria gonorrhoeae.

This study summarized the experiences of disease-specific performance appraisal at tertiary hospitals in Shanghai,which was launched since year 2013 by Shanghai Hospital Development Center (SHDC). 38 tertiary hospitals in Shanghai were included in the study. A disease-specific performance appraisal system centering on quality and performance, by means of case-mix model, classified surgery management and typical disease screening, and leveraging disease and surgery difficulties analysis, and inter-hospital performance appraisal of typical diseases. This reform has established appraisal criteria of disease difficulty management,coding criteria and data norms,guiding such hospitals to consolidate their functional positioning of focusing on difficult,urgent and complicated cases in the medical service delivery system.All these efforts have paved the way for the reforms to build a hierarchical medical service system, pricing per disease, payment per disease, and consolidate performance appraisal of medical workers.

Objective To prepare hepatocyte growth factor(HGF) recombinant protein and confirm its activity preliminarily according to building HGF gene prokaryotic expression vector and transforming into E.coli.Methods Clone HGF inserted into the vector pET-26b(+) to construct prokaryotic expression vector pET-26b(+)-HGF and transform into E.coli Rosseta(DE3).The transformed bacteria induced by IPTG was purified through Ni-NTA resin affinity chromatography frozen-drying after renaturation.Results HGF gene recombinant prokaryotic expression vector pET-26b(+)-HGF was constructed successfully.E.coli Rosseta(DE3) which was transformed into pET-26b(+)-HGF expresses the target protein as the form of inclusion bodies,accounting for 38% of the total bacterial proteins,and confirmed by Western blot.HGF protein which was purified by Ni-NTA resin affinity chromatography,has a purity of about 95%,and can promote proliferation,migration,and inhibition of apoptosis for human non-small cell lung cancer cell line A549 cells after interaction.Conclusion HGF gene recombinant prokaryotic expression vector pET-26b (+)-HGF was constructed and expressed in transformed E.coli Rosseta(DE3) successfully.They resumed their recombinant HGF protein structure after purification and renaturation,and had biological activity confirmed by in vitro studies.

OBJECTIVETo observe the inhibition of NK4 protein in the proliferation of human Raji lymphoma xenografts in nude mice, and to explore its molecular mechanism.
METHODSModels of human Raji lymphoma xenograft transfected with HGF gene were established by subcutaneous inoculation in nude mice. After establishment of the models, the mice received continuous NK4 protein via tail vein for 4 weeks, and the weight and tumor growth were monitored every week. After 8 weeks, the expression of HGF mRNA and c-Met mRNA of tumor tissues was measured by real-time fluorescent quantitation PCR. The apoptotic index (AI) and microvessel density (MVD) were evaluated by terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) and immunohistochemistry, respectively.
RESULTSThe models of human Raji lymphoma xenograft were successfully established. Although the animal weights of all groups declined, especially in the groups with NK4 protein injection, there was no statistical significance (P > 0.05). The tumor volume in HGF gene transfected group was larger than those of the control groups (P < 0.01), and there was no statistical significance among the control groups (P > 0.05). However, the tumor volume of the NK4 protein injection group decreased significantly (P < 0.01). Expression of HGF mRNA and c-Met mRNA in HGF gene transfected group increased significantly after injection of NK4 protein (P < 0.01). AI in HGF gene transfected group (33.5% ± 12.3%) was significantly lower than that of control groups (89.1% ± 22.3% vs. 81.9% ± 27.0%, P < 0.05), but became significantly higher (119.1% ± 18.9%) after NK4 protein injection (P < 0.01). MVD in HGF gene transfected group (28.5 ± 2.0) was higher than that of control groups (12.2 ± 1.4, 13.8 ± 1.3, P < 0.01), although declined (15.5 ± 2.5) after NK4 protein injection (P < 0.01).
CONCLUSIONSNK4 protein suppresses significantly the growth of human Raji lymphoma xenografts transfected with HGF gene. The pathogenesis may be involved in promoting tumor cell apoptosis and restraining tumor angiogenesis through competitive interrupting HGF/Met signal pathway.
