ABSTRACT

Objective To evaluate the risks of vaccination operation in order to provide scientific basis for policy makings of vaccination operation.Methods The risk matrix and analytic hierarchy process approach were used to evaluate the risks of vaccination operation,including the possibility,severity,risk weight,and risk level.Results Seven items for the first level and thirty one items for the second level vaccination risk factors were determined.In the first level,E level risk (Extremely serious risk ) was vaccination implementation risk,and H level risk (high risk ) was the risks of pre -notification and health education and risks of vaccine and cold chain management.Vaccination implementation risk accounted the largest weight (weight coefficient=38.95%).In second level,E level risk was three inspection and seven verification before vaccination,and H level risk were personnel professional quality,personnel responsibility,pre -inspection,informed before vaccination, vaccination route, site and dose, vaccination operation, post vaccination notification and retention,and three inspection and seven verification before vaccination,accounted the largest weight (weight coefficient=10.14%).The weight of the logical consistency of the test results were satisfactory (consistency ratio<0.1 ).Conclusion The integrated application of risk matrix and analytic hierarchy process in risk assessment of vaccination operation helps to further regulate vaccination services and has application and promotion value.

ABSTRACT

BACKGROUND: Psoriasis is an autoimmune disease that is caused by a shift in the Th1/Th2 balance toward Th1-dominant immunity. It has been established as an effective treatment to counteract psoriasis by subcutaneous injection of recombinant interleukin (IL)-4, and IL-4 gene therapy by topical transdermal penetration has shown its antipsoriatic effect in mice. Retinoic acid (RA) and dimethylsulfoxide can increase the efficiency of gene transfection in the topical transdermal delivery system. OBJECTIVE: We investigated whether RA could improve anti-psoriasis efficiency using IL-4 expression plasmid pORF-mIL-4 (pIL-4) via transdermal delivery system in K14-vascular endothelial growth (K14-VEGF) factor transgenic mice. METHODS: After pretreatment with RA, plasmid pIL-4 in 10% dimethylsulfoxide was applied to the ear skin by topical transdermal penetration. Hematoxylin- eosin staining and immunohistochemistry were performed with ear samples to evaluate anti-psoriasis efficiency in mice. RESULTS: The psoriasis pathological features were relieved and psoriasis-associated factors were significantly reduced. CONCLUSION: Our results reveal that topical application of pIL-4 in dimethylsulfoxide by transdermal delivery with RA pretreatment can improve psoriasis significantly.
