Naive and chronically infected C57BL/6 mice were challenged percutaneously over the ear pinna with Schistosoma japonicum cercariae. After 15 hours, the number of EOS increased significantly in the skin of chronically infected mice. Inflammatory cells aggre-gated in the vicinity of schisto.somula or entrapped intact and disintegrated schistosomula, forming granulocytic micro-abscesses in both groups. Ultrastructure studies revealed that flattened EOS tightly attached to the schistosomulum surface and degranulated. Local tegument damage occurred in the area of attacbment. NEU adherence did not seem to be as intimate as EOS, and degranulation was not seen. The tegument of the attached schis-tosoniulum remained normal. The result suggested that EOS appeared to be the efficient killer cell against skin phase schistosomula of S. japonicum (Figs. 1-6).

Objective To analyze the effect and safety of budesonide combined with psychological intervention on the treatment of the children with bronchitis. Methods 60 children with capillary bronchiolitis in Enze hospital from June 2014 to May 2016 were randomLy divided into the control group and the experimental group, 30 cases in each group. The control group were received conventional treatment, such as, anti-inflammatory, antiviral, bronchodilator and oxygen inhalation. At this basis, the experimental group were given budesonide aerosol inhalation combined with psychological intervention. The clinical therapeutic effect in the two groups were compared. Results The cough stopping time, hospitalization time and the time of lung wheezing rale in the experimental group were significantly shorter than those in the control group, and the adverse reactions in the experimental group were significantly lower than those in the control group, and the difference between the 2 groups was statistically significant(P<0.05). Conclusion The children with capillary bronchiolitis patients were given budesonide inhalation combined with psychological intervention on the basis of routine therapy, which can effectively improve the clinical symptoms, improve the curative effect, low incidence of adverse reactions, shorten the treatment time, which is worthy of clinical application.

Objective To study the therapeutic effect of Fumaderm in Freund' complete adjuvant-induced arthritis (AIA) in Spraque-Dawley rats. Methods Adjuvant-induced arthritis (AIA) was established by intradermal injection of 0.1 mL of Freund' complete adjuvant (CFA) in the palmar surface of the right hindpaw and Fumaderm was delivered by oral gavage for 28 days. After CFA injection, the edema of the hindpaw was determined every two days. On 28 days after CFA injection, the lymphocyte subsets of peripheral blood and the cytokines were determined by flow cytometry, meanwhile the histopathological examination of ankle-joints of the animals was performed. Results Fumaderm had a significant therapeutic effect on AIA. The hindpaw swelling was reduced significantly in a dose-dependent manner. The ratio of peripheral blood T lymphocytes was improved obviously. Multiparameter cytokine analysis from peripheral blood CD4+ T cells showed a decrease of proinflammatory cytokines and an increase of anti-inflammatory cytokines in Fumaderm treated animals. A strongly reduced inflammatory response in the joint synovium was observed. Conclusion Fumaderm has potential anti-inflammatory effects on AIA rats. Further investigation is needed to elucidate the molecular mechanism involved in the clinical effect observed in the AIA model.

Abstract] Objective To establish an assay for the detection of porcine parvovirus ( PPV) and to verify its application for monitoring cells used for production.Methods A pair of primers and one probe were designed according to the conserved sequence encoding non-structural protein 1 (NS1).Based on the designed primers, a real-time fluorescent quantitative PCR assay for the detection of PPV was developed. Several parameters including the linearity, precision, minimum detection limit and anti-interference of the established assay were evaluated.A stock of PPV strains was prepared by infecting swine testicle ( ST) cells with PPV strains.An assay for the detection of PPV infection was developed by using ST cells as sensitive cells.A combined ST cell infection-PCR test was developed by combining the ST cell infection assay with the real-time fluorescent quantitative PCR assay.The sensitivity of ST cell infection-PCR test was analyzed.The cell samples used for production of biological products were detected by using the established assay.Results The real-time fluorescent quantitative PCR assay was specific for the detection of PPV without cross-reaction to other species of parvovirus virus, SV40 virus and other porcine viruses.The linear range of the assay was 1×109-1×104 copies/μl with a R2 value more than 0.98.The sensitivity of the real-time quantitative PCR assay was 1×104 copies/μl.Both of the intra-and inter-coefficient of variation (CV) were less than 5%in Ct values.The intra-and inter-CV in copies of detection were 5%-15% and 30%-40% respectively.The minimum detection limit of the real-time fluorescent quantitative PCR assay was 1CCID50/ml.The PPV strains were detected in cell samples with no interference.The sensitivity of ST cells infection-PCR test was 0.01CCID50/ml.All of the 22 cell samples were negative for PPV by using the real-time fluorescent quanti-tative PCR assay.Conclusion The real-time fluorescent quantitative PCR and the ST cell infection-PCR test for the detection of PPV in cells were established successfully.The application of the two assays was conducive to further enhance the safety of using cells for production and therapy.

OBJECTIVE To learn about the factors affecting the quality of the air in operating-rooms and discuss the methods of improving their air quality.METHODS The dynamic and static air bacteriology between laminar air flow operating-room and normal operating-room of a fertiary care level hospital of grade Ⅰ in Changchun were observed.RESULTS The passing rate of samples for air static bacteriology between two types of operating rooms at the begining of selective operations(T0) was without difference.At the begining of emergency operations,there was a disparity.The total number of bacteria in normal operating-room increased with the operating-time,but in the laminar flow operating-room,the total number of bacteria increased in fluctuations during the(T2) time(60 ming since operation begain),and descended dramatically during the(T3) time(90 min since operation).CONCLUSIONS The emergency and operation-time are the main factors affecting the air quality in operating-room and the cleaning air-condition could improve the air quality.
