A clinical emergency skill contest using emergency care simulator (ECS) was carried out　on May 2011.Total 30 family physicians in 10 teams from Shenzhen community health centers participated in　the contest.The performance and the scores of each item were analyzed.The overall score was 61.3 ± 11.9.The average score for general treatment was 33.0 ± 6.9 with a score rate of 66％ (33/50) ; the average　score for cardiopulmonary resuscitation was 23.2 ± 7.2 with a score rate of 57.5％ (23/40) ; the average　team score was lowest (5.0 ± 1.1 ) with a score rate of 50.0％ (5/10).The results indicate that family　physicians should strengthen clinical skill training of emergency care,particularly in on-site response and　teamwork.

Objective To investigate the effects of continuous end-eiastoloc volume index(CEDVI) adjusted by right venteicular ejection fraction(RVEF) in using for volume resuscitation of critically ill patients.Methods 51 critically ill patients who Swan-Ganz volume pulmonary artery catheters were inserted in via right internal jugular or subclavian vein underwent fluid therapy.Fluid was infused according to the relationship of RVEF and CEDVI.And the relationship of RVEF and CEDVI was that when RVEF was 0.2,0.3,0.35,0.4 and 0.5,respectively,CEDVI is 200～400ml/m~2,150～180ml/m~2,125～150ml/m~2,100～120ml/m~2,50～60ml/m~2 respectively.When RVEF is

Objective To explore the changes in serum plasminogen activator inhibitor 1(PAI-1),tissue factor(TF) and antithrombin Ⅲ(ATⅢ) in early period of severe limb injury,and their relationship with the occurrence of traumatic pre-DIC and DIC after trauma.Methods Thirty-five patients were divided into severe injury group(AIS score ≥3,20 cases),minor injury group(15 cases),and 10 healthy subjects served as control.The 35 patients with injury were divided again into pre-DIC group(10 cases),DIC group(3 cases),and others(22 cases).Fasting peripheral venous blood was collected on day 1,3,6 from the patients and healthy subjects.The changes in TF,ATⅢ and PAI-1 levels were detected and statistically analyzed.Results The PAI-1 levels were higher in minor injury group and severe injury group than that in control group on day 1(P

Objective Human bone marrow mesenchymal stem cells were transfected by Smad7 and labeled with green fluores-cent mark.BMMSCs were implanted into rabbit glaucoma operational model and observed surviving condition.Methods Through BP and LR reaction,Smad7 with green fluorescent mark was inserted into human bone marrow mesenchymal stem cells by bacterio-phage,filtered positive colony and picked out cell line.15 New Zealand white rabbits were enforced trabeculectomy with BMMSC, then following up cell survival condition.Results Smad7 expressed stable in human bone marrow mesenchymal stem cells with sat-isfactory green fluorescent mark.BMMSC survived in rabbit trabecula with stable green fluorescent and effective ocular press.Con-clusion Smad7 with green fluorescent mark could be inserted into human bone marrow mesenchymal stem cells stably,and has ef-fective results in rabbit model.

This article mainly summarise the results of the chemical compositions and their pharmacological activities of Arnebiae Radix since 1966. The chemistry components isolated from Arnebiae Radix are mainly naphthoquinone, monoterpene phenol and quinone, phenolic acids and their salts, alkaloids, aliphatic and esters. Pharmacological results showed that the chemical compositions and the extracts of Arnebiae Radix have antibacterial, anti-inflammatory, anti-viral, hepatoprotection, antioxidant, anti-tumor and immune function and other activities. This article hopefully to provide a reference for further research, development and utilization of Arnebiae Radix.

BACKGROUND: Stromal cell-derived factor 1 (SDF1), a potential inhibitor of infection by lymphophilic HIV-1 strains, can help to block the pathway of HIV-1 invasion into the human body.OBJECTIVE: Genotype and polymorphism of SDF1-3 'A allele associated with HIV-1 infection were investigated in She Ethnic Group in the south of China so as explore the possible causes of uninfection by HIV-1 strains among this population.DESIGN: Single sample study.SETTING: Department of Biochemistry and Molecular Biology, Gannan Medical College.PARTICIPANTS: Totally 186 She Ethnic subjects without HIV-1 infection collected randomly from those whose three generations belonged to She Ethnic Group, and inhabited in Qianshan County of Jiangxi Province,Ningde area of Fujian Province and Jingning She County of Zhejiang Province, from January to December 1995.METHODS: The whole blood samples from 186 She Ethnic subjects were collected randomly, and then their genomic DNA samples were extracted respectively. Allelic polymorphism was examined by the polymerase chain reaction and restriction-fragment-length polymorphisms (PCR-RFLP).MAIN OUTCOME MEASURES: The distribution of SDF1-3'A allele in She Ethnic Group in the south of China.RESULTS: The data of 186 She Ethnic subjects entered the result analysis without any loss in the midway. The frequency of SDF1-3 'A allele in She Ethnic Group samples was 19.6%, and the allelic distribution of the gene was in accordance with Hardy-Weinberg equilibrium. No difference was found between male and female individuals.CONCLUSION: The frequency of SDF1-3 'A allele of She Ethnic Group in the south of China was similar to that of Dai Nationality in Yunnan.Based on its slow-down effect on clinical course of AIDS, the mutation of SDF1-3'A is significant in the prevention and treatment of AIDS in She Ethnic Group in the south of China.

Objective To investigate the effects of silenced Racl on invasion and migration in LOVo cells.Methods The expression of Racl mRNA and protein in colorectal cancer cells(including LoVo SW480.SW620.SW1116,HT29)were detected by RT-PCR and Western blot,respectively.The changes of cytoskeleton were observed in LoVO cells after transfected with Racl-shRNA.then invasion and migration were recorded respectively in LoVo cells after transfected with Racl-N17 and Racl-L61.Results Racl mRNA and protein were overexpressed in all selected colorectal cancer cells.Deletion of Racl decreased the cross-linked actin network and pseudopodia,and inhibited the invasion and migration in LoVo cells.The migration experiment showed that the migrated cells were higher in Racl-shRNA[(75±5)cells].Racl-N17 [(93±5)cells]and Racl-L61[(267±7)cells]groups compared with control group[(214±8)cells,P＜0.01,＜O.01 and＜0.05,resprectively].The invasion experimental study revealed that the migrated cells were higher in Racl-shRNA[(35±5)cells],Racl-N17[(42±5)cells]and Racl-L61[(86±7)cells] groups compared with control group[(73±6)cells,P＜0.01,＜0.01 and＜0.05,resprectively].Condusion Deletoin of Racl can inhibit the invasion and migration in LDVo cells.

Objective To investigate the guidance role and effect of the thoracolumbar injury classification and severity score (TLICS) in the choice of anterior,posterior or combined surgery for thoracolumbar fractures.Methods Thirty-one consecutive patients with acute thoracolumbar burst fractures who were treated in an our unit were selected as our subjects who hospitalized from Oct.2006 to Sep 2010,There were 20 male and 11 female patients.The average age was 44.7 years (range from 35.0 to 56.0 of all patients 3 was injured T11,6 at T12,7 at L1,8 at L 2 and 7 at L3.The reasons of injury include motor vehicle accident (10 cases)and falling from a height (24).All patients had preoperative anteroposterior and lateral radiographs,computed tomography (CT) scan,and magnetic resonance imaging (MRI) examination to more fully assess vertebral pieces and nerve compression.According to the Classification of Maged,there were 8 cases with type A3,8 cases with B1,9 cases with B2,3 cases with C1,3 case with C2.Neurologic status based on Frankel classification showed that 4 cases were with grade A 8 with grade B,9 with grade C 6 with grade D and 4 with grade E.Of the 31 patients,11 received posterior surgeries,12 anterior surgeries,and 8 combined anterior and posterior surgeries.Results Twenty-eight cases were followed up with averaged 13.7 months (range from 12.0-17.0 months).The kyphosis angle was measured from the superior endplate to the inferior end plate of the fractured vertebral body using the Cobb technique.The mean cobb's angle was (23.7 ± 11.3) ° (range,13.0 ～ 38.0°) preoperatively,(5.8 ± 0.6°) (-4.0 ～ 6.0) ° lordotic post operatively and (11.3 ± 10.6) ° lordotic at the final observation.The average surgical time was 190 minutes (range,90-380 minutes).and blood loss was 1680 ml (range,1260-2540 ml),and hospital stay was 17.4 days (range,10-24 days).No eloosening or motion was observed in the final follow-up patients.Conclusion TLICS has facilitate treatment decision making of thoracolumbar spinal column injuries and proved to be an effective treatment for serious thoracolumbar fracture.
