Objective To investigate the clinical value of antibody D5F3 and Survivin in patients with non small cell lung cancer.Methods 200 paraffin embedded specimens of patients with non small cell lung cancer tested by RT-PCR(including EML4-ALK mutant and wild type)from October 2012 to June 2014 were selected.The gene protein expression were tested by ALK new antibody D5F3 and the sensitivity and specificity were compared by negative and positive(+～3+).ResultsTest results show(+)the coincidence rate is 15.78％,(+ +)the coincidence rate is 27.27％and(+ + +)compliance rate was 87.5％,the difference was statistically significant(P<0.05).The expression of Survivin protein in NSCLC tissues was correlated with clinicopathological features.The positive rate of Survivin protein expression was correlated with the degree of differentiation(P<0.05),but not with other clinical and pathological features,with the decrease of differentiation,the positive rate of Survivin protein expression was significantly increased.Conclusion D5F3 and Survivin antibodies are highly sensitive and specific in patients with NSCLC,with the screening value,save social resources,for the majority of patients with lung cancer services.

Objective To evaluate the therapeutic efficacy of agitating thrombolysis technique for Budd-Chiari syndrome complicated with inferior vena cava (IVC) fresh thrombus. Methods From August 2004 to March 2009, 5 patients of Budd-Chiari syndrome (four males and one female, aged 36-48 years) with IVC fresh thrombus were treated with agitating thrombolysis technique. After anpography of IVC the recanalization of IVC was performed, which was followed by agitating thrombolytic therapy. Finally,IVC was dilated with percutaneous transluminal balloon angioplasty. Clinical follow-up of IVC patency was conducted by color Doppler sonography. Results After agitating thrombolysis. The thrombi were completely disappeared in all 5 patients without single occurrence of pulmonary embolism. In all patients, IVC remained patency on color Doppler ultrasonograph after following up for a mean period of 23.8 months. Conclusion Agitating thrombolysis technique is a safe and effective treatment for Budd-Chiari syndrome complicated with IVC fresh thrombus.

Objective To elucidate the efficacy and safety of transcatheter closure of secondary atrial septal defect (ASD) with Amplatzer septal occluder (ASO) in people over 50 years of age. Methods Retrospective comparison of 41 patients (14 males, 27 females) with ASD over 50 years of age ranging from 50 to 75(mean age 55.5?7.6, elder group) was conducted with 132 patients younger than 50 years(control group). After diagnosis of ASDs and evaluation of pulmonary artery systolic pressure and right atrial and ventricular dimensions by transthoracic echocardiography (TTE), all patients underwent transesophageal echocardiography (TEE) for complete assessment of ASD size, margins and anatomic relationship of the defect before closure of ASD. Each case was treated with ASO through the percutaneous transcatheter procedure under fluoroscopy and TTE or TEE. Early follow up(3 months) by echo was taken after the intervention. Results There was no difference of mean defect diameter measured by TEE and the balloon-stretched defect diameter of the ASDs between 2 groups. Pulmonary artery pressures in elder group were higher than those in younger group(P

Objective To explore the application of high-frequency color Doppler in the diagnosis of infant intussusception and the selection of reduction mode according tO the hemodynamic situations of intussusception intestine tube and blood vessel in mesentery.Methods A total of 377 cases of doubtful intussusception infants wete checked by high-frequency color Doppler.After they had been diagnosed,the hemodynamic situations of intussuscepiton intestine tube and blood vessel in mesentery were carefully observed and the ultra-sound had 3 types and then the hydrostatic enema reduction was chosen as treatment method.Results A total of 263 cases was diagnosed by highfrequency colot Doppler with rate of coincidence of 100%.Among them are 253 successful cases reduced by hydrostatic enema.The successful rate of reduction was 96.2%and the 10 failed cases were changed to be treated bv operation.The intestinal wall of intussusception tube in failure group had serious dropsy without blood flow shown.Conclusions It is accurate that the infant intussusception is diagnosed by high-frequency color Doppler.According to the hemodynamic situations of intussusceptin intestine tube and blood vessel in mesentery,the infant intussusception can be divided into 3 types as follows:type Ⅰ:the blood signal of intestinal tube and wall is up or normal,which shall be reduced by hydrostatic enema;type Ⅱ:the blood signal of intestinal tube and wall is small with high obstruction index,which shall be reduced by hydrostatic enema as possible as it can;type Ⅲ:the intestinal wall has serious dropsy with rather high obstruction index and without blood flow shown,in which the hydrostatic enema redHetion shall bebanned and the operation shall be carried out as soon as possible.

Objective To explore the ultrasonographical characteristics of placental abruption, especially the light placental abruption that was diagnosed by color Doppler ultrasonic combining with enhancement Doppler E-flow imaging, providing diagnosis data for clinical treatment. Methods With color Doppler ultrasonic and enhancement Doppler E-flow imaging, an analysis was made on the ultrasonography and clinical result of 50 patients with heavy placental abruption and 23 patients with light placental abruption. Results The diagnosis and clinical treatment of 50 patients with heavy placental abruption who had been diagnosed by color Doppler ultrasonic combining with enhancement Doppler E-flow imaging were in conformity with the postnatal pathological diagnosis. The coincidence rate in diagnosis was 100%. Of 23 patients with light placental abruption who had been diagnosed by color Doppler ultrasonic combining with enhancement E-flow Doppler imaging, 19 cases' diagnosis and clinical treatment were in accordance with their postnatal pathological diagnosis and the coincidence rate was 83%, 4 cases were misdiagnosis and missed diagnosis. Of 73 patients with placental abruption, 60 cases were carried out caesarean birth and 13 cases performed natural labor. Conclusion The enhancement Doppler E-flow imaging combining with color Doppler ultrasonic can accurately diagnose the heavy placental abruption and also provide a new method for the diagnosis of light placental abruption and perform a dynamic monitoring for the treatment transfer result of it.

The scores of the four callu s and th e depth of the lateral callus in Group A were higher than those in Group B. Con clusion ZS has obvious effect in promoting the union of fracture.

Objective:To construct double-layered controlled release system containing SDF-1 and rhBMP-2 molecules and to study the release profile of the system in vitro.Methods:The polylactic acid/chitosan(PLA/CS)nanoparticles were prepared with “emulsification-solution evaporation method”,the preparation parameters were determined by orthogonal test design.The particle size was observed by nanoparticle size analyzer,the morphology of the nanoparticles was observed with electron microscope.Then rhBMP-2 and SDF-1 were loaded into the nanoparticles in the process of emulsification,the loading efficiency and encapsulation efficiency were calculated and in vitro release was observed.Results:The double-layer nanoparticles showed spherical geometry,smooth surface and complete separation. The average particle size of the nanoparticles was (542.33 ±14.38)nm;The drug loading and incorporation efficiency of rhBMP-2 were (82.41 ±1.05)% and (24.67 ±0.43)ng/mg,those of rhBMP-2 were (75.58 ±0.84)% and (22.63 ±0.41)ng/mg,respectively. The release time of the drug from the system sustained over at least 30 days,the release profile of both drugs showed “biphasic release”.
