Objective To observe the effect of volume resuscitation on the early grafted kidney function in opration.Methods 909 cases were divided into five groups according to the volume resuscitation in opration:group A:

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.

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

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.

Accessory navicular source flatfoot is one of the foot deformity of clinical common disease,its treatment method is more controversial, differences in clinical efficacy of different surgical methods, according to accessory navicular source flatfoot symptoms of surgical treatment,there is no uniform standard, around a pair of accessory navicular excision how to reconstruct the arch produced a series of operation methods, the clinical curative effect of different operative methods produce also different, how to develop the operation strategy, choose operation method, and after acessory navicular excision whether to rebuild posterior tibial tendon, how to rebuild, the problems such as how to rebuild is the research hotspot and difficulty, looking forward to further research.

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 compare the effect of two different treatment approaches on femoral shaft fractures in polytrauma patients.Methods One hundred and forty-eight polytrauma patients were selected as our subjects,who were hospitalized from Jan.2000 to Dec.2009.They were randomly divided into cast group and external fixation group.Patients in cast group were fixed with cast within the first 24 h after the injury and patients in external fixation group were stabilized with a unilateral external fix stent within the first 24 h after the injury.Results In cast group,71 of 75 patients were followed up and follow up periods was 26.4 months.Follow up data showed that 18 patients developed multiple organ failure (MOF) and 26 patients developed ARDS.The average healed periods was 5.9 month.Three patients developed nonunion and 4 cases developed wound infection.The average of the knee motion angle was 107 degrees (60 to 110 degrees).In external fixation group,68 patients were followed up and the follow-up period was 27.5 months.Of which,13 patients developed MOF and 12 patients developed ARDS.The average healed periods was 5.6 months.2 patients developed nonunion and 3 cases developed for.wound infection.The average of the knee motion angle was 120 degrees (60 to 140 degrees).Conclusion The damage control orthopedics surgery was proved as a safe and effective treatment approach for fractures of the shaft of the femur in selected multiply injured patients compared with cast methods.
