Objective To evaluate the efficacy of endovascular interventional minimally invasive techniques in treatment of acute brachial artery injury.Methods A retrospective case series study was designed to analyzed data of 16 cases (11 males and 5 females) sustaining acute brachial artery injury treated from March 2011 to August 2016.Mean age was 47.9 years (range,27-66 years).Left upper extremity vascular injury occurred in 7 cases and right upper extremity vascular injury occurred in 9.There were 13 cases of arterial intima injury and 3 of arterial pseudoaneurysm.All patients underwent endovascular therapy including stent implantation and balloon dilatation.Angiography was used to evaluate the repair of brachial artery and the operation time was recorded.Improvements of distal limb arterial pulse and limb ischemic symptoms were observed,and the patients who were followed up with stent lumen stenosis more than 50％ received endovascular treatment again.Results The procedures was successful in all patients,with operation time of 30-75 minutes (mean,45 minutes).After the insertion of a stent,recovered brachial artery blood flow and disappeared pseudoaneurysm were observed on angiography,without occurrence of stent stenosis or contrast extravasation.Symptoms of local pain and numbness were alleviated,and blood supply of the distal brachial artery was improved after operation.All patients were followed up for 3-36 months(mean,16.7 months).The false aneurysm did not recur.Two cases of stent stenosis more than 50％ had a second balloon dilation procedure and the blood flow returned to normal.Stent patency was found in 14 cases with stent stenosis of less than 50％.During the follow-up period,no ischemic necrosis,displacement of the stent or stent fracture were found.Conclusion For acute brachial artery injury,endovascular management exhibits higher technical success rate and good clinical outcome with a low incidence of complications.

The occurrence of malignant tunors is increasing annually around the world.In every year,8.2 million patients died of malignant tumors in which about 90％ patients died of malignant tumors associated multiple organs metastases.Inhibiting tumor metastasis is the key event to prolong the survival time of patients.With the further research,tumor-vessel associated extravascular tumor metastasis is playing an increasingly important role in the clinical application.This paper summarizes the new developments of tumor-vessel associated extravascular tumor metastasis to provide possible ideas for the therapy of malignant tumors.

Objective To screen the conservative,stable and specific DNA signature sequence in the plasmid of Yersinia pestis.Methods Specific validation trials and stability of the qualification test were carried out to 40 strains of Yersinia pestis,47 strains of non-Yersinia pestis of home and wild types of rodent in Yunnan,by using 32 DNA sequences derived from Yersinia pestis in the plasmid and conventional PCR technology,and Yersinia pestis vaccine strain EV76 as a positive control.Results Four pairs of relatively conservative,stable and specific DNA marker genes were screened:YPMT1.05c,YPMT1.03c,YPMT1.42 and YPMT1.04c.Conclusions The 4 pairs of Yersinia pestis DNA signature sequences can be used for rapid diagnosis of plague.

A moderately halophilic bacterium strain DF-B6 capable of degrading Tween 20 was isolated from solar saltern brine by plate method.Based on the phenotype,physiological and biochemical character-istics,and the phylogenetic analysis of 16S rDNA sequence,strain DF-B6 was identified as Idiomarina.The substrate specificity test showed that the lipolytic enzyme from strain DF-B6 was an esterase,and not a li-pase.The maximum esterase activity was observed in 8% NaCl concentration at 50?C,pH 8.0.The effect of various divalent cations was studied on the activity of esterase from Idiomarina sp.DF-B6 at the concentra-tion of 10 mmol/L,Mg2+,Ca2+ and Mn2+enhanced the esterase activity,while Zn2+,Fe3+ and Cu2+ inhibited its activity.

ObjectiveTo investigate the hemostatic effect of fibrin sealant (FS) powder on severe wound surface and find out the minimum effective dosage.Methods1 cm2 round wound surface was made on the liver of New Zealand white rabbits. Different dosages of FS powder were administrated on the wound surface. Bleeding time and bleeding volume were examined to find out optimized dosage. Hemostatic effect of FS powder was observed and compared with chitin cotton, gelfoam and normal gauze.ResultsBleeding time (0.57±0.21 min)and bleeding volume (0.35±0.29 ml)of FS 10 mg/cm2 group were obviously different from FS 8 mg/cm2 group (P<0.05), not significantly different from FS 12 mg/cm2 group. FS 10 mg/cm2 group got the shortest bleeding time and the lowest bleeding volume, which was obviously different from chitin cotton, gelfoam and gauze groups (P<0.05～0.01).ConclusionThe hemostatic effect of FS powder is better than gelfoam, chitin cotton and gauze and its optimized dosage is 10 mg/cm2.

ObjectiveTo observe the effect of Ornidazol on acute pericoronitis of wisdom tooth (PWT).Methods125 patients with PWT were randomly divided into the experiment group (63 cases, treated with Ornidazol) and control group (62 cases, treated with Metronidazole). The curative effect was observed when teeth extracted.ResultsThe effective rate of the experiment group was 95.2%, that of control group was 82.2%. There was a significant difference between two groups (P<0.05).ConclusionOrnidazol has an obvious effect on acute PWT.
