[Objective]To compare the effects of anatomical lateral distal tibial plate and clover plate fixation for the treatment of closed distal tibial fracture.[Method]A retrospective survey was analyzed in our hospital from May 1999-May 2008.A total of 85 cases of closed distal tibial fracture were followed up.Forty-three were fixed by the lateral distal tibial anatomy plate and 42 cases by alfalfa grass plate.The clinical effects were analyzed and compared by operative time and fracture healing time.T test and x2 test were used for statistical analysis.P

Objective:To monitor the effects of asarone injections on the expression of IL-25, IL-27 and eosinophils cationic pro-tein ( ECP) in the serum of asthma patients. Methods:Totally 100 patients with bronchial asthma were randomly divided into the ob-servation group ( 55 cases ) and the control group ( 45 cases ) . The control group was treated with the conventional symptomatic treat-ment ( oxygen inhalation, spasmolysis and anti-asthma, and anti-infection, etc) . The observation group was given asarone injections 24 mg in 250 ml 0. 9% sodium chloride infusions, once a day for 14 days on the basis of the conventional therapy. The changes in symp-toms, and pulmonary function in the patients were observed with simultaneous detection of IL-25, ECP and IL-27 levels. Results:To-tal effective rate of the observation group was 92. 7%,which was higher than that of the control group (P<0. 05). Asarone injections could decrease IL-25, ECP and IL-27 levels in the observation group compared with those in the control group with statistically signifi-cant difference (P<0. 05 or 0. 01). Conclusion:Asarone injections can decrease the levels of IL-25, IL-27and ECP in the serum of asthma patients and inhibit the formation of inflammatory cells to alleviate the symptoms of airway inflammation.

From 1970 to 1984,100 patients with esophageal cancer survived over 10 years after radiotherapy alone. In theis group 58 male, 42 female; section of upper thoracic 53, section of middle thoracic 47; medullary type 82, fungoid type 14; tumor length ≤5cm 49, 5.1～7.0cm 34, 7.1～9.0cm 17. They were teated by three or four intersecting radiation, total doses were 50～70Gy. 9 patients received second radiotherapy for local relapse. In 100 patients, 58 patients still survived , 42 patients died of local relapse 18, bleeding 6 and fistula 4. 5 patients suffered from radiation myelitis and 3 patients fracture of rib in 58 living patients. Conclusion: the result of treatment is better in group of young people. Patients with supraclavicular metastasis have received seccond radiotherapy after first raditherapy could still survive for a long time. Local relapse is the important factor for death yet. We think total dose is adapted between 50～70Gy. The spinal received dose

A review of cell traction forces (CTFs) measurement based on Biological MiCro Electromechanical Systems (BioMEMS) microposts matrix is presented.CTFs are exerted by cells and ansmitted to the underly-ing substrate through focal adhesions and close contacts.which is essential for cells movement.Cells probe the mechanicaI compliance of the exlracellular mabix (ECM) in part by locally deforming it with nanonewton-scale traction forces.Precision measurement of CTFs is significant for many researches such as call biology and tissue engineering and so on.Enabled by the advancement in BioMEMS technology,surface treated high aspeect ratio Polydimethyisiloxane(PDMS)micropos matrix devices,which serve as BioMEMS sensom for de-tecting cellular nanoforces and studying in vitro cell mechanics,have been developed.Closely spaced vartical microposts matrixes were designed to encourage cells to attach and spread across multiple microposts,and to bend the microposts like vertical cantilevers as the cells locomote on the surface.Using this dense and dis-crete matrix of microposts rather than a convanfional continuous substrate,CTFs can be directly measured and quantified by processing the microscopy images of the deformations of microposts.The resolution of the force was in tens of nN/μm scale.At first,the conventional CTFs measurement methods were concisely summa-rized.Then BioMEMS microposts matrix method was described in detail,including principle and fabfication process,Surface treatment and cell expedment results.Furthermore,high aspect ratio structure collapse prob-lem was investigated.

Objective To evaluate the video-assisted thoracoscopic surgery(VATS) in the diagnosis and treatment of open thoracic traumas. Methods From July 2003 to July 2008,video-assisted thoracoscopic surgeries,including thoracic exploration,repair of the pulmonary laceration,parietal pericardium and diaphragm,hemostasis,evacuation of the clotted hemothorax,and mini-incision thoracotomy,were carried out in 64 selected patients with open thoracic traumas. Results Via VATS,all the 64 patients were diagnosed accurately: pulmonary laceration in 43(56 lesions),pericardiac rupture in 7(one of them showed right ventricular rupture),diaphragmatic rupture in 9(5 of them were complicated with spleen rupture,1 with hepatic rupture,and 1 with gastric rupture perforation),single intercostal vessel injury in 5,and combined intercoastal vessel injury in 3.The procedures involved VATS pulmonary laceration repair in 24(combined with thoracic wall hemostasis in 2),VATS combined mini-incision thoracotomy pulmonary laceration repair with Endo-GIA in 11(silk suture was employed in 6,and pulmonary wedge resection in 2).Through VATS procedure,hemostasis and repair were completed for pericardiac repair in 3,and diaphragmatic repair in 5.Thirteen cases were converted to open thoracic surgery.The duration of VATS procedure ranged from 32 to 124 minutes with a mean of 65.8 minutes.After the procedure,6 patients developed pneumothorax,4 showed mild subcutaneous emphysema,and 9 had slight hemoptysis in 1 to 12 days after the treatment.The patients were followed up for 2 to 60 months(mean,28.5 months).Chest X-ray performed during the period showed no pleural effusion,pneumothorax or other trauma-related complications.Conclusion VATS is effective for the diagnosis and treatment of open thoracic traumas with less surgical injuries and good outcomes.

Objective To investigate the variation and clinical significance of serum levels of inflammatory cyto-kines after percutaneous coronary intervention (PCI)treatment in acute myocardial infarction (AMI)patients. Methods 118 incipient AMI patients with successful underwent PCI (Defined as treatment group,blood samples were collected from pre-operation,12 h after operation,24 h after operation,48 h after operation and 90 d postop-erative follow-up period)and 52 AMI patients with diagnostic coronary angiography (CAG)(Defined as control group,blood samples were collected prior to CAG,12 h after CAG,24 h after CAG,48 h after CAG and 90 d fol-low-up period)were enrolled in this study.Serum levels of IL-6,IL-18,hs-CRP,TNF-αand MMP-9 were detec-ted in all the subjects by enzyme-linked immune sorbent assay(ELISA)and major adverse cardiac events(MACE) occurrence rate was analyzed in 90 days followed-up cases.Results No significant differences in baseline levels of IL-6,IL-18,hs-CRP,TNF-αand MMP-9 were found in the two study groups(P >0.05).No significant differences of levels of IL-6,IL-18,hs-CRP,TNF-αand MMP-9 were found after CAG in control group (P >0.05).The serum levels of IL-6,IL-18,hs-CRP and TNF-αafter PCI were significantly increased (P <0.01 )while no significant differences were found in level of MMP-9 (P >0.05)in PCI group.There were significant differences of levels of IL-6,IL-18,hs-CRP and TNF-αbetween MACE group and without MACE group after PCI.The multivariable lo-gistic analysis showed that IL-6,IL-18,hs-CRP and TNF-αwere risk factors of MACE after 90 days follow-up. Conclusion The concentrations of serum IL-6,IL-18,hs-CRP and TNF-αare significantly increased in AMI pa-tients treated with PCI.PCI operation may induce inflammatory reaction.High serum levels of peripheral inflamma-tory cytokines IL-6,IL-18,hs-CRP and TNF-αhave an important role in major adverse cardiac events(MACE)and short-term prognosis in the first AMI patients treated with successful primary PCI.

To explore an appropriate treatment for patients with upper ureteral stone (＞ 15 mm in size) by comparing the therapeutic outcomes for those undergoing retroperitoneoscopic ureterolithotomy (RPUL) and percutaneous nephrolithotomy (PCNL).A total of 62 patients with large upper ureteral stone were divided randomly into 2 groups.RPUL was performed in group A (n =30) and PCNL in group B (n =32).No significant inter-group difference existed in age,gender,stone location and size,operative duration or surgical success rate (P ＞ 0.05).Blood loss volume,rate of postoperative analgesic usage,time of hospital stay and incidence of postoperative complications in group A were significantly lower than those of group B (P ＜ 0.05).Thus RPUL offers more advantages and better efficacies.

Objective To evaluate the safety and effectiveness of mechanical thrombectomy with Solitaire AB stent in the treatment of large intracranial artery occlusions.Methods The calinical data of 15 patients with acute stroke(more than 3.5 h intravenous thrombolysis time window) who were carried out arterial embolectomy with Solitaire AB stent in the No.264th Hospital of the Chinese People's Liberation Army were retrospective analyzed.There were 11 cases of middle cerebral artery(MCA),2 cases of internal carotid artery (ICA),1 case of vertebral artery(VA) pluse basilar artery(BA),and 1 case of anterior artery(AA).The recanalization occluded situation and surgical complications were analyzed,NIHSS score of preoperatively and at discharge were compared.Results In 15 cases,there were 14 cases of totally recanalization,1 case of partial recanalization.Two case with MCA stenosis and 1 case with VA stenosis after the recanalization were accepted stent angioplasty,2 csase died.NIHSS score of 13 cases survival patients increased from (22.85±4.75) scores on admission to (4.39 ±3.67) scores out of hospital,and the difference was statistically sinificant(t=2.752,P ＜0.01).Conclusion The mechanical thrombectomy with Solitaire AB stent can get high recanalization rate,fewer complications and good clinical outcome on patients with large intracranial artery occlusions.For more than venous or arterial thrombolysis time window,the mechanical thrombectomy can be considered within the 8 h after comprehensive evaluation.

Objective To explore the feasibility, safety and the efficacy of peroral endoscopic myotomy (POEM) for pediatric patients with achalasia.Methods A total of 21 patients (mean age 2 years, range 11 months-7 years) with AC were enrolled and underwent POEM from January 2012 to December 2014.Procedure-related complications, reflux esophagitis were observed.Eckardt score and the pressure of the lower esophageal sphincter (LES) were analysed.Results All patients underwent POEM successfully.No serious POEM-related complications were observed.During a mean follow-up period of 20.4 months (range 9-36 months), mean Eckardt score decreased from 8.1 to 0.8 after treatment (P ＜ 0.01).Mean LES treatment also decreased from 30.2 mmHg to 11.5 mmHg after the operation (1 mmHg =0.133 kPa, P ＜ 0.01).Reflux esophagitis developed in four patients (19.0％ ,4/21).Conclusion POEM is safe and effective treatment for pediatric patients with achalasia.

Objective To investigate the relevance between protein expression and methylation of MG-MT and hMSH2 in glioma patimts.Methods Immunohistochemical and methylation specific PCR were adopted respectively to test on 275 cases of glioma patients for the protein expression and methylation situation of MGMT and hMSH2.Results The negative protein expression rate of MGMT and hMSH 2 in the tissue of brain golima were 47.2% and 62.5% respectively;the occurrence of methylation in gene promoter region were accordingly 41.8% and 22.4%.Statistical analysis revealed that MGMT promoter methylation in peripheral blood gene groups was related with the protein negative expression of tumor tissue (P<0.05),while there was no relationship between the protein expression of hMSH2 and its gene promoter methylation(P>0.05).Conclusion The meth-ylation of MGMT is a common molecular situation in the generation of brain glioma ,which may be connected with that of tumor.However,hMSH2 promoter methylation might not the main reason for inactivation of hMSH 2 pro-tein,there may be other important factors affecting its expression .
