Objective To explore the causes of short P R interval syndrome.Methods 15 patients of short P R interval syndrome were tested with transesophageal atrial pacing (TEAP),and then the results and the parameters of TEAP were analyzed.Results The detection rates of dual atrioventricular nodal pathways(DAVNP),L G L syndrome and latent preexcitation syndrome were 66.67%(10/15),26.67%(4/15)and 6.67%(1/15)respectively.Conclusion The most common causes of short P R interval syndrome are DAVNP and the L G L syndrome

To observe the effect of IL-2 gene modification on the character of biology and function in dendritic cells( DC) and to investigate the immune mechanism of specific anti-tumor of IL-2 gene modification in DC. Methods: DCs were prepared from mouse bone marrow and genetically modified by IL-2 adenovirus. Then observe the changes of DC morphology by scanning electro-microscopy, analyzed molecules on DC by FACS, examined the expression of IFN-? mRNA in DC by RT-PCR.The stimulatory capacity of DC to T cells detected by MLR their capacity of antigen present were measured by 3H-TdR mix into assay. Results: After IL-2 gene modification, the morphology of DC was changed, its pseudopod was more and longer. The expression of Ia, B7-1, B7-2 and CD40 molecules was more on DC surface. The IFN-7 mRNA was expressed in the DC-EL-2 and DC-rhIL-2.DC-IL-2 could stimulate allogeneic T cells more potently and IL-2 gene-modified DC could induce more potent antigen-specific autogeneic CTL. Cooclusioo: IL-2 genetic modification can promote DC growth and up regulate their expression of membrane immune molecules that are relevant for antigen presentation of DC,and enhanced the biologic activity of the DC.

Objective To study current status of health education and explore its pattern in community health-care service(CHS)in Shanghai.Methods A total of 200 health-care workers(HCWs)from five CHS centers in Shanghai were investigated by questionnaire of health education knowledge.Results Among 200 HCWs investigated,96.5%(193/200)of them have recognized importance of health education,98.0%(196/200)could undertake health education in their clinical work,only 60.5%(121/200)had receired regular training on it,and 85.5%(171/200)thought they should be further trained regularly.Correct awareness of knowledge was 94.O%.47.0%and 33.6%for health education perception,healthy life-style and health education knowledge for chronic disease.respectively in them.There was very significant difference in correct awareness of knowledge between HCWs with varied ages and districts(χ2=17.663 and 82.376,P=0.001 and 0.000,respectively),but no significant difierence was found between men and women and those with varied professional titles(χ2=0.015 and 2.406,P=0.903 and 0.300.respectively).Short of time(48.5%),lack of relevant knowledge(15.0%)in HCWs and poor compliance of patients(33.0%)were main factors influencing their implementation of health education.Conclusions HCWs in CHS have already recognized importance of health education.but have not known enough its theoretical knowledge and skills.It is necessary to set guidelines of health education intervention for HCWs in CHS,and perfect monitoring and evaluation.as well as mechanism for rewards and penalties to promote development of health education in CHS.
