Coxsackievirus A(CV-A)is a common virus associated with a number of serious human diseases,including menin-gitis,myocarditis,herpangina,conjunctivitis and hand,foot and mouth syndrome. In recent years,with the increase of epidemics events with CV-A as the main pathogen,the studies focusing on the CV-A infection have attracted more attention. In this paper,we comprehensively review the basic characteristics,pathogenesis and potential antiviral drugs of CV-A.

Transcatheter arterial chemoembolization (TACE) has been widely applied in palliative treatment of unresectable primary and metastatic liver cancer,and its efficiency and safety also have been widely acknowledged.However,there is a wide range of related complications,such as upper gastrointestinal hemorrhage,liver failure,pulmonary embolism,embolic cholecystitis and so on.As a serious complication of TACE,bile duct injury has been reported intermittently since the introduction of hepatic arterial embolization therapy.However,the exact pathogenesis,predisposing factors and clinical implications of the injuries remain to be clarified.As we find,by far there is no literature review about the bile duct injury after TACE for liver malignant tumors both at home and abroad.Thus the purpose of our study was to discuss such current issue of bile duct injury,and 26 articles have been included and analyzed.

The degranulation of mast cells represents a pivotal e-vent in the allergic disorders.The Src family kinases(SFKs)are as a starting signal in the activation of mast cell.Lyn,Fyn and Syk play important regulatory role in the degranulation of mast cells.Regulating SFKs can reduce the degranlation process and inhibit the allergic disorders.Therefore,SFKs inhibitors can be potential drugs in the allergy.It is necessary to study the targeted medicine of SFKs,which will be a new direction of drug develop-ment.

Objective To summarize the key points in surgical cooperation of laparoscopic left lateral segment liver resection. Methods The clinical data of 24 patients undergoing laparoscopic left lateral segment liver resection from March to September of 2013 were analyzed retrospectively to summarize the key points in surgical cooperation of preoperative preparation and intraoperative coordination.Result All the operations were successful with the operation mean time of(72.0±26.8)min,no intraoperative transfer or termination of the operations.Conclusion Sufficient preoperative preparation together skilled surgical nursing cooperation in laparoscopic left lateral segment liver resection is critical for the success of operation.

Objective To investigate the distribution and antibiotic resistance of gram-negative bacilli for better antimicrobial therapy in our hospital.Methods A retrospective analysis was conducted for the 1 060 strains of gram-negative bacilli isolated from clinical specimens during 2013.Results Of the 1 060 gram-negative bacterial strains isolated during 2013,E.coli,K . pneumoniae,P .aeruginosa and A.baumannii were the leading pathogens,accounting for 29.3%,22.8%,11.5% and 9.9%,respectively.The prevalence of extended spectrum-lactamases (ESBLs)positive strains was 63.7%,32.2% and 28.0% in E.coli,K .pneumoniae and P .mirabilis,respectively.The Enterobacteriaceae strains were highly sensitive to carbapenems.The percentage of the P .aeruginosa isolates resistant to meropenem,imipenem or amikacin was lower than 30%.The percentage of the Acinetobacter spp.(A.baumannii accounted for 70.9%)strains resistant to meropenem and imipenem were 25.0% and 26.2%.Conclusions Most of the gram-negative bacilli are resistant to multiple antimicrobial agents. We should strengthen the monitoring of the antibiotic resistance of gram-negative bacilli and optimize antimicrobial therapy.

Objective: To study the biological characteristics of tumor cells infected with recombinant adenovirus expressing hTNF-?, investigate the antitumor effect of recombinant adenovirus. Methods: Human lung adenocarcinoma cell line Anip973 was infected with recombinant adenovirus expressing hTNF-?. Cell growth assay, colone formation test, flowcytometry assay and morphology were used to observe the effects on tumor cells. The hTNF-a gene, which was transduced into cancer cells mediated by recombinant adenovirus, was detected by PCR and agarose gel electrophoresis and its products were detected by ELISA assay. The intratumoral injection of rAd-LacZ and rAd-hTNF-? was carried out to evaluate their antitumor effects. Results: The liter of rAd reached 1010 PFU/ml and more than 90% Anip973 cells could be infected by 30MOI rAd. Except the surface structure and ultrastructure of tumor cells infected with rAd had a light change, cell growth abillity assay, colone formation test, flow cytometry assay showed no significant difference compared with that of the control cells. The TNF-? gene expression at 24 h increased greatly. Antitumor study indicated that on the tumor-bearing mice treated with rAd the tumor grew slowly. Tumor volume was significantly smaller and survive time was prolonged than that of controls. Conclusion: There was no significantly changes occurred on tumoral cells after infected with recombinant adenovirus expressing hTNF-?. The intratumoral injection of rAd-LacZ and rAd-hTNF-? could inhibit the growth of solid tumor.

Objective To compare the effect of percutaneous intraluminal radiofrequency ablation ( RFA ) combined with biliary stenting and that of percutaneous transhepatic puncture combined with biliary stenting .Methods A total of 56 patients with unresectable malignant obstructive jaundice were reviewed retrospectively .Among them, 25 patients had received percutaneous intraluminal RFA combined with biliary stenting ( RFA group) while another 31 patients had been simultaneously selected for the simple biliary stent implantation ( stent group ) .The changes of the serum total bilirubin ( TB) and direct bilirubin ( DB) before and after 7-14 days of treatment , surgical complications , stent median patency and the median survival were observed.Follow-up information was obtained through telephone reviews or check-up records. Results The technical success rate was 100%.No procedure-related peritonitis or perforation occurred .There were respectively 3 cases with cholangeitis in RFA group and 3 in stent group.All the cases was controlled by effective clinical treatment.There was obvious statistically significant difference after treatment in TB and DB in the two groups (P<0.01, P<0.01).TB and DB fell by (149.05 ±110.71) and (96.93 ±69.12)μmol/L after 7-14 days in RFA group vs (151.40 ±94.47) and (94.21 ±67.36)μmol/L in stent group.The changes of the two groups were of no statistical significances .The stent patenmedian time was 122 ( 9 -550 ) and 157 ( 16 -510 ) d, while the median survival was 125(9-550) and 163 ( 16 -520 ) d.The difference was of no statistical significance .Conclusion Percutaneous intraluminal RFA combined with biliary stenting and percutaneous transhepatic puncture combined with biliary stenting are both safe and feasible therapeutic options for unresectable malignant obstructive jaundice .There is no statistically significant diffference between the two groups in the recent and long-term curative effects .
