Objective To study the role of focal adhesion kinase in the breast carcinoma cell adhesion and migration mediated by coagulation factor Ⅶa combined with tissue factor to explore the mechanism of tissue factor promoting metastasis. Methods The count of adherent cells were detected by using colorimetric assay,cell migration was detected with modified Bodyen chamber,and the FAK and the tyrosine phosphorylation of FAK were detected by immunoprecipitation and Western blot.Results Factor Ⅶa combinaed with tissue factor induced the tyrosine phosphorylation of FAK,which took part in the cancer cell's migration.Conclusion FAK is an important message of the breast carcinoma's adhesion and migration mediated by TF.

Objective To study the Genotype of local clinical isolates of Enterobacteriaceae producing extended spectrum ? lactamases. Methods K B test, conjugative transfer test, plasmid profile analysis, PCR, PCR RFLP, and DNA sequencing were used to detect the phenotype and genotype of 33 isolates of Enterobacteriaceae producing ESBLs. Results Eighty five percent of 33 isolates was resistant to cefotaxime which was obviously higher than that to ceftazidime. blaCTX M ESBLs was detected in 28 isolates by PCR, blaTEM DNA in 24 isolates, and blaSHV DNA in 9 isolates. Mutation of E104K was only identified in one TEM ? lactamase produced by EC98A7 by PCR RFLP. No substitution of G238S occurred in 9 SHV ? lactamases. DNA sequencing and DNA alignment showed the blaCTX M DNA fragments from 4 clinical isolates of EC98A7,EB56,CFR78 and, KP9941 belonged to CTX M type 1, with highest identity to blaCTX M 3 or blaCTX M 12 respectively. Conclusions CTX M ESBLs is carried in 85% isolates of Enterobacteriaceae producing ESBLs in this city. Most of the isolates carry 2 or more ? lactamases. E. coli EC98A7 produces two ESBLs, a TEM ESBL and a CTX M ESBL.

The pediatric risk of mortality Ⅲ(PRISM Ⅲ) score and pediatric critical illness score(PCIS) are physiology-based scores for assessing the severity of illness and mortality risk in pediatric patients.The PRISM Ⅲscore was revised version of the PRISM and was first developed in 1996.It includes 17 physiologic variables subdivided into 26 ranges.It had been validated by numerous studies worldwide and is the most widely known and used at pediatrics intensive care unit(PICU).The PCIS was first developed in 1995 in China,which included 10 physiologic variables.It had been validated by numerous studies nationwide and was simple,effective and suitable to Chinese situations.The scoring systems also can be used for quality assessments,grading the severity of illness in clinical study,and(stu)-dies of ICU resource utilization and management.There were no such study for validating the PRISM Ⅲ at present,comparing the performance of the PRISM Ⅲ score and the PCIS in China.

Objective To evaluate whether patients with BI‐RADS category 3 breast lesions can be managed safely by 1‐year follow‐ups using ultrasound elastography .Methods Data from 164 patients who underwent conventional B‐mode ultrasound and ultrasound‐based elasticity examinations from September 2009 to March 2014 ,and had BI‐RADS category 3 lesions that appear to be circumscribed and oval in shape with elasticity scores of 1 -2 ,were retrospectively reviewed .Results Of 331 BI‐RADS category 3 lesions that originally appeared circumscribed and oval in shape in 164 women ,the mean follow‐up period was 21 3. months (range ,12-48 months) ,and 330 (99 7.% ) were unchanged at follow‐up and considered probably benign .One lesion was upgraded to BI‐RADS category 4a ,and a subsequent biopsy pathologically confirmed it was a fibroadenoma .Conclusions BI‐RADS category 3 lesions with elasticity scores of 2 or lower can be reclassified as BI‐RADS category 2 lesions .A 1‐year follow‐up may be adequate for women undergoing screening ultrasonography ,which are found to have BI‐RADS category 3 lesions that appear to be circumscribed and oval in shape with elasticity scores of 1-2 .
