Design and Application of Intelligent Follow-up Visit Management System of Hospitals / 医学信息学杂志

Taking the First Hospital Affiliated to Traditional Chinese Medicine University of Guangzhou as an example,the paper puts forward to establish the hospital's intelligent Short Message Service (SMS) follow-up visit system based on the analysis of research conditions and existing problems of domestic and overseas follow-up visit system,introduces the follow-up visit registration process and functional modules,and summarizes the application efficiency.This system can greatly improve the follow-up visit efficiency,reduce the rate of loss to follow-up visit,and immediately update information of patients.

Altered perlecan expression in the formation of epidural scar after posterior lumbar laminectomy / 中华骨科杂志

Objective To make a research on the expression of perlecan in the formation of epidural scar after posterior lumbar laminectomy in the rat.Methods Sixty Wistar rats were randomly and evenly divided into five groups:the experimental groups including A(the first week after surgery),B(the second week),C(the fourth week),D(the sixth week)and the control group.Laminectomy was performed on lumbar vertebra in each experimental group.The hematoxylin-eosin(HE)staining was used to observe the formation of epidural scar.Immunohistochemistry was performed to detect the perlecan located in the epidural scar.Western blot and RT-PCR were made to quantify the expression of the perlecan after surgery.Results According to HE,with prolonged,the scar tissue gradually formed.Immunohistochemistry demonstrated that the perlecan was expressed in the fibroblast.Western blot and RT-PCR showed the high level expression of perlecan in the experimental groups compared to the control group(P＜0.01).Furthermore,the expression of perlecan gradually increased with the prolongation of exposure time and had significantly statistical significance (P＜0.01)between the first three experimental groups.However,compared to the fourth week group,the expression of perlecan in the sixth week decreased obviously(P＜0.01).Conclusion Perlecan was expressed in the fibroblast of the epidural scar,and which plays an important role in the formation of epidural scar.
