Objective To explore the efficiency of writing admissions records with the electronic medical record system. Methods 16 interns with the same educational backgrounds and residency periods were randomized into 2 groups and wrote admissions records respectively with the electronic system and by hand, the traditional method. 1 week later, the same records were again written by the two groups, now each using the other's method. The time for completing each part of the records was noted down in real time across the entire process. The time taken by the interns to complete the records was changed into marks of speed, the assessments of the records by experts were changed into marks of quality, and composite marks resulted from the two after weighting. Statistical testing was done with the two methods. Results In terms of time, the average total time taken by the electronic and traditional groups was respectively 19. 85 m and 39. 49 m; in terms of quality, the electronic group got higher marks in scores for present, past, personal, and family histories and physical examination and in the overall score; in terms of general efficiency, the electronic group got average marks of 91. 13 while the traditional group got average marks of 65. 72, the difference being statistically significant (P

Objective:To investigate the role of chemokine receptor CX3CR1 in chronic skin inflammation and its regulatory mechanism.Methods:Wild type (WT) C57BL/6 mice and Cx3 cr1 GFP/GFP mice were induced by DNFB to establish acute and chronic allergic contact dermatitis (ACD) model. Ear inflammation and swelling were observed with hematoxylin-eosin (HE) staining. Flow cytometry (FCM) was used to detect the changes in classical Langerhans cell (LC) and monocyte-derived LC (Mo-LC), as well as the expression of major histocompatibility complex Ⅱ (MHCⅡ), inducible nitric oxide synthase (iNOS) and TNF-α. Changes in epidermal LC in UV irradiation-induced dermatitis models were also analyzed. In human chronic skin inflammation, CX3CL1 expression was detected using immunohistochemistry, RT-PCR and Western blot and CD1a, CD14 and CD207 expression was observed with immunofluorescence staining. Results:In the chronic ACD model, Cx3 cr1 GFP/GFP mice showed significantly alleviated ear inflammatory and swelling as compared with WT mice, but no significant difference was found in the acute ACD model. The percentages of Mo-LC were decreased in the chronic ACD model and after three weeks of UV irradiation. Moreover, MHCⅡ, TNF-α and iNOS expressed by Mo-LC were significantly upregulated as compared with those by classical LC. CX3CL1 expression was significantly upregulated and the numbers of CD14 + monocytes and CD1a + langerin - Mo-LC were dramatically increased in human chronic skin inflammation. Conclusions:CX3CR1 might maintain inflammatory response by regulating local remodeling of Mo-LC in chronic skin inflammation.
