Objective To evaluate the effect of clinical pathway management on pediatric capillary bronchitis. Methods Infants with capillary bronchitis admitted to our hospital were selected. Several indices were compared between the infants with and without clinical pathway management including hospital stay, costs of hospitalization, satisfaction in parents of children, cure rate, readmission rate one week after discharge, hospital infection and variation in the process of clinical pathway manage-ment. Results A total of 204 eligible infants were divided into research group (n=96) and control group (n=108). There were no signiifcant differences in sex, age, respiratory rate, heart rate and temperature, and detection rate of respiratory syncytial virus in nasopharyngeal secretion and sputum culture (P>0.05). Compared with the infants in control group, the total drug costs, the an-tibiotics costs and the average length of stay were signiifcantly decreased in infants with clinical pathway management (P<0.05). There were no signiifcant differences in such indices as satisfaction in parents of children, cure rate, readmission rate one week after discharge and hospital infection rate between two groups (P>0.05). In research group, 49 infants (51.04%) completed the clinical pathway management. Positive variance was found in 43 infants (44.79%) and negative variance in 4 infants (4.17%). Two infants (2.08%) dropped out. Conclusions For capillary bronchitis in infants, clinical pathway management has an effect on controlling and reducing the medical expenses, and meanwhile improving the medical quality and satisfaction of patients.

Objective To investigate the relationship between the X-ray,CT findings and its pathological basis of nonossifying fibroma(NOF).Methods X-ray and CT features of NOF confirmed by surgical pathology in 17 cases,and correlative study of imaging andpathology was done.Results 17 lesions were showed as eccentric and expanded destruction located in the cortex,and the remains of bone could be found inside the tumor,the lesions projecting into marrow cavity with a thin bone between the tumor and marrow.The tumors were grey-yellow or brown tissue around by the thin bone found in operation.NOF was consisted of a lot of shuttle cell and collagen fiber under microscope,some of macrophagocyte with multiple nucleuses and foam cell dropped disseminating in them,and there was not osteogenesis in the tumor.Conclusion The pathological changes of NOF can be reflected by X-ray and CT.

Objective:To find a short, neutralizing antibody-inducible, ORF2-encoded protein by means of comparing the immunogenicity of pN472-C617 and pN477-C613 which represent amino acids 472-617 and 477-613 of HEV ORF2-encoded protein of hepatitis E virus(HEV) genotype 4, respectively.Methods:The two recombinant proteins were expressed, purified, and then used to immunize BALB/c mice. Anti-HEV titers in the immune sera were detected by ELISA. Anti-HEV neutralizing activity was tested by a PCR-based in vitro neutralization assay.Results:Both of the two recombinant proteins were efficiently expressed in E.coli in soluble forms. The purified proteins induced mice to develop high levels of anti-HEV specific antibodies. However, only the immune sera obtained from the mice immunized with pN472-C617 showed the neutralizing activity to the homologous HEV strain by preventing the virus from absorption on PLC/PRF/5 cells surfaces and replication in the cells. The immune sera against pN477-C613, which was truncated five amino acids from both N- and C-terminal of pN472-C617, had no HEV neutralizing activity.Conclusion:The pN472-C617 is the shortest neutralizing antibody-inducible ORF2-encoded protein of HEV reported in literatures so far. It may be considered as a potential candidate for a novel HEV subunit vaccine in our future study.
