OBJECTIVE To investigate resistant genes encoding ?-lactamases and aminoglycoside modifying enzymes in Pseudomonas aeruginosa isolated from clinical specimens,and phylogenetic analysis was performed.METHODS Antimicrobial susceptibility test was performed by PhoenixTM-100 system.Resistant genes encoding ?-lactamases,aminoglycoside modifying enzymes and antiseptic resistance were detected by PCR amplification and verified by DNA sequencer.RESULTS The resistant rates of ?-lactams including ampicillin/sulbactam,piperacillin,piperacillin/tazobactam,cefotaxime,ceftazidime,cefepime,imipenem and meropenem in 190 strains of P.aeruginosa were 98.9%,59.5%,45.8%,77.4%,34.2%,38.4%,15.3% and 6.8%,respectively.Ciprofloxacin and levofloxacin still showed powerful activities with resistance being 15.3% and 21.0%.The positive rates of blaVEB, blaGES and blaCARB genes were 9.5%,9.5% and 57.1% in 21 isolates.Twenty strains lost oprD2 genes.However,the ?-lactamase genes of TEM,SHV,OXA,PER,IMP,VIM,SPM,GIM and DHA were not found.Three resistant genes encoding aminoglycoside-modifying enzymes were found in 21 isolates,such as aac(6′)-Ⅰ,aac(6′)-Ⅱ and ant(2″)-Ⅰ,and they accounted for 9.5%,61.9% and 66.7%,respectively.The positive rate of qacE△1-sul1 genes was 66.7% in 21 isolates.CONCLUSIONS P.aeruginosa isolated in clinic has carried many resistant genes.The loss of oprD2 gene may be the important cause of P.aeruginosa resistant to imipenem.Cluster analysis indicates that the spread of clones occurred in our hospital.

Objective To study the influence of short hairpin RNA-mediated inhibition of APRIL gene on proliferation,invasion and metastasis of human colon carcinoma SW480 ceils in vitro. Methods After treatment with shRNA, the expression level of APRIL protein in human colon carcinoma SW480 cells was detected by western blotting. And cell adhesion, cell migration and cell invasion of SW480 cells transfected with sh637 were analyzed respectively as compared with non-transfected SW480 cells and mocktransfectant. Results The expression of APRIL protein in SW480 transfected with sh637 were significantly lower than mock-plasmid groups and untransfected ones (F=42.15, P=0.00). Cell proliferation was markedly inhibited, compared with untransfected groups and negative control ones (F=24.76, P<0.05).And the average absorption of cell adhesion in transfected groups, mock-plasmid and non-transfected ones were 0.343, 0.409, 0.412, respectively. Cell adhesion decreased 39% compared with untransfected groups. Similarly, there was significant difference for cell migration (F=65.53, P<0.01) between transfected groups (The average ceil number in exposed area to migrate was 47.89±13.16) and nontransfected (98.78±23.26) as well as mock-plasmid ones (108.01±39.11). Then, in view of the average absorption of cell invasion between transfected groups(0.58±0.10) and non-transfected (0.94±0.23) as well as mock-plasmid ones(1.11±0.21), a prominently difference for cell invasion was also found between them (F=5.771, P<0.05). Conclusion The results suggest APRIL has a proliferation-inducing effect and probably be involved in cell invasion and cell metastasis of colon carcinoma and it could enhance capacity of invasion and metastasis of SW480 cells.

Purpose To study the clinicopathologic features of inflammatory myofibroblastic tumor (IMT) of long bone.Methods HE and immunohistochemistry of EnVision two-step were used to observe the clinical,radiological,histological and immunophenotype features of IMT of bone.The literatures were reviewed.Results 4 cases of IMT of bone were respectively located in the tibia (2 cases) and femur (2 cases).Histologically,the lesions were characterized by collagen-rich and spindled to plump myofibroblast-like cells and a variable admixture of inflammatory cells.Immunohistochemical study showed that the vimentin,SMA,actin,H-caldesmon and CD34 were positive.Conclusion The IMT is a rare and locally aggressive tumor.The diagnosis should combine the histological characters with immunohistochemical results and should be differentiated from the other tumors and tumor-like lesions.

Objective To investigate the influence of diabetes mellitus (DM) on left ventricular(LV) remodeling in patients with acute ST-segment elevation myocardial infarction (STEMI) treated by primary percutaneous coronary intervention (PCI) within 12 hours of symptom onset. Methods Four hundred and fifty-one consecutive patients with acute STEMI treated by primary PCI were prospectively enrolled in the current study. Baseline, angiographic and PCI features and prevalence of LV remodeling at one-week during hospitalization and 6-month clinical follow-up by two-dimensional echocardiography were compared between 93 diabetic and 358 non-diabetic patients. Results Despite similar baseline clinical and angiographic characteristics, symptom-to-door time was longer (399±106 min vs. 321±116 min, P=0.006) and prevalence of multivessel disease was higher (65.6%vs. 51.7%, P=0.02) in diabetic patients. More patients in diabetic group had LV remodeling at 6-month clinical follow-up (29.0%vs. 17.3%, P=0.01), and DM was an independent predictor of LV remodeling (RR 2.1, 95%CI 1.31-4.79, P=0.02). The rate of rehospitalization due to heart failure did not differ between diabetic and non-diabetic patients (12.9%vs. 8.1%, P=0.15), however, more adverse events occurred in patients with LV remodeling comparing to those without LV remodeling (25.8% vs. 6.6%, P < 0.001). Conclusions Diabetic patients with STEMI often have an increased risk of LV remodeling after treated by primary PCI. Thus, comprehensive therapeutic strategy for diabetic patients presented with STEMI is required considering the poor prognosis of these patients with LV remodeling.

Objective To investigate the effects of a proliferation-inducing ligand(APRIL) on migration and invasion of colorectal cancer (CRC) and matrix metalloproteinases (MMPs) expression in order to observe the role of APRIL in CRC metastasis.Methods The siRNA plasmid vector targeting APRIL gene (siRNA-APRIL) was transfected into SW480 cells and recombinant human APRIL(rhAPRIL) was used to stimulate HCT-116 cells.Tumor cell migration and invasion were measured by Transwell chambers.RT-PCR and ELISA were applied to examine the expression level of MMPs.Results Metastatic and invasive capacities of siRNA-APRIL transfected SW480 were significantly inhibited,and these capacities of APRIL stimulated HCT-116 cells were significantly enhanced compared with their respective controls( all P＜0.05 ),accompanied with the alterations of MMPs mRNA and secreted protein expression( P＜0.05).The number of invading cells of SW480 control and rhAPRIL stimulated HCT-116 was significantly decreased by a MMP inhibitor GM6001 ( P＜0.05 ).Conclusion APRIL facilitates migration and invasion of CRC via regulation of MMPs,which suggests that APRIL might be used as a new target for the intervention and treatment of CRC metastasis.

Objective To prove the remarkable inhibitive effect of multiple siRNAs targeting a proliferation-inducing ligand (APRIL) on the human colorectal cancer cell.Methods We constructed a multiple short hairpin RNA(shRNA) expression vector containing four shRNAs (pG4) as well as four single one (pGsh644,pGsh1451,pGsh1938,pGsh2231) against APRIL gene in SW480 cell,and then transfected them into the human colorectal cancer cell line by cationic liposome.Ultimately,SW480 were screened by EGFP to obtain expression cell lines.APRIL expression levels including mRNA and APRIL protein were detected after transfected with all different kinds of vectors.Results A multiple shRNA expression vector containing four shRNAs (pG4) and four single ones were successfully constructed.Four single vectors (pGsh644,pGsh1451,pGsh1938,pGsh2231) and the multiple siRNAs expression vector (pG4) all decreased the APRIL mRNA by 56.2％,49.5％ ;50.9％,49.2％ and 79.3％.And APRIL protein expression was also remarkably reduced,especially by multiple siRNAs expression vector(87.5％).Conclusion Multiple siRNAs expression vector produced a more significant knockdown effect of APRIL than the vectors containing only one APRIL shRNA.What we found suggested us using the vector containing multiple shRNA to silence the expression of APRIL might be exploited as a novel therapeutic strategy for tumors.
