Objective To provide patients and medical personnel with quality, highly effcient, and reasonably priced logistical services by forming specialized entities of logistical services and following the path of specialization, intensity and market mechanisms. Methods The principles of overall planning, phase-by-phase implementation and steady promotion were adhered to and the functions of logistical management and services were separated in accordance with the ideas of separating management and operation and the goals of outsourcing logistical services. Results The traditional models of "being small but complete" and "a hospital setting up a society" were transformed and new models of logistical management and services were established. Conclusion There has emerged a new pattern of outsourcing logistical services, with both sides sharing resources and complementing each other's advantages.

ObjectiveTo investigate the difference of pathogenicity between the two genotypes of human metapneumovirus(hMPV) for the further research.MethodsAt various time after hMPV infection in BALB/c mice,viral titers of lung tissue were measured by real-time RT-PCR,pathology was assessed by a histopathological scoring system,airway responsiveness was assayed by animal lung function monitoring equipment.Pathogenicity was then measured by detailed evaluation through the results above.Results There is no significant difference in weight of mice between control group and experimental group through dynamic monitoring ; though the difference was exists in airway responsiveness and pathological changes of mice between control group and experimental group,the differences were not statistically in airway reaction,pathological changes and virus drops among the three groups of experimental group.ConclusionThere is no difference in pathogenicity between the two subtypes of hMPV in infection of BALB/c mice,viral genotype do not appear to be associated with pathogenicity.

Objective To compare WHO 2004 and WHO 1973 pathological grading methods of non-muscle invasive urothelial neoplasms. Methods The clinical pathological features of 160 non-muscle invasive urothelial neoplasms patients, treated in our hospital from February, 1998 to Decem-ber, 2008, were re-graded according to WHO 2004 and WHO 1973 classification system. To evaluate recurrence and progression of all the patients during the follow up period, we used statistical method to analyses the differences between two classification system. Results There were 160 patients, ac-cording to WHO 1973 classification methods: 5 cases of papilloma, 52 cases of grade 1 tumors, 83 ca-ses of grade 2 and 20 cases of grade 3;By WHO 2004 classification method: 7 cases of papilloma, 31 cases of low-grade malignant potential of urothelial papilloma, 99 cases of low-grade papillary urotheli-al carcinoma and 23 cases of high-grade papillary urothelial carcinoma. There was no difference in re-currence among the grades of WHO 2004 and WHO 1973 pathological grading system (both P>0.05). Regarding the progress of non-muscle invasive papillary urothelial neoplasms, no significant difference was found among grades of WHO 1973 classification system(P>0.05)while difference exis-ted among grades of WHO 2004 pathological grading system (P<0.05), especially between papillary neoplasm of low malignant potential (PNLMP) and high grade papillary urothelial carcinomas(HG-PUC) (P<0.01). Moreover, HGPUC grade had more progression rate (30.4%) than G_3 grade (15.0%). Conclusions Compare to G_3 grade, HGPUC grade was more easily to make progress in pa-tients,due to this grade include more high malignant papillary urothelial carcinomas. Therefore, it is necessary for urologists to use a more rigorously follow up and therapy method in connection with HG-PUC grade of new classification system.
