OBJECTIVE：Analyzing the epidemic of drug risistance bacteria with extend spectrum β-lactamase(ESBLs)in children's wards to cut off the transmitting pathway and prevent the outbreak of nosocomial infections in time.METHODS：Samples，including sputum，umbilical secretion，pus，pharyngeal swab，were collected from in-hospital child patients in Departments of Newborn，Respiratory Tract Diseases，Cardiology，Nephrology，Hematology，Pediatric Surgery and ICU，then bacterial cultures and drug susceptibility test were carried out.54 strains of ESBLs E.coli and Klebsiella pneumoniae were isolated and their plasmid profiles were analysed by agarose electrophoresis.RESULTS：The percentages of ESBLs in the above-mentioned departments were 46.3，12.9，5.6，12.9，5.6，11.1，5.6 respectively.In analysis，three types of profiles were found and strains with four types of the same profile concentrated in the Newborn Department.The others were dispersed.CONCLUSION：Nosocomial infections possibly occured in the Newborn Department to some extent.

AIM: To study the effect of genistein on c-myc mRNA expression induced by oxidized low density lipoprotein (ox-LDL) in human vascular endothelial cells (ECV304). METHODS: LDL were isolated from healthy human plasma by gradient ultracentrifugation and oxidized by CuSO4. ECV304 cells were exposed to ox-LDL 200 mg*L-1 in the presence or absence of genistein 100 μmol*L-1 for 1, 2, and 4 h in vitro. Northern blot was employed to measure c-myc mRNA levels of ECV304. RESULTS: In response to ox-LDL 200 mg*L-1, c-myc mRNA expression in ECV304 increased by 3 fold for 1h and 3.3 fold for 2 h and decreased below the control level at 4 h. Expressions of c-myc stimulated by ox-LDL in the presence of genistein 100 μmol*L-1 for 1 h and 2 h were separately 80 percent and 60 percent of that in the absence of genistein 100 μmol*L-1. CONCLUSION: Genistein can effectively inhibit c-myc mRNA expression in ECV304 induced by ox-LDL.

Human rhinoviruses (HRVs) are the causative pathogens in more than half of viral upper respiratory tract infections. Currently, no antiviral agents that are active against HRVs are available for clinical use. Because only higher primates are susceptible to HRVs, the screening of new drug is most commonly based on the cell line model. In this study, isolated rabbit airway smooth muscles (ASM) tissue model has been established, and the airway responsiveness with different treatment has been examined. Relative to control tissues, the maximal constrictor (Tmax) response to ACh increased significantly 150% in ASM inoculated with HRV, and relaxation to isoproterenol has been attenuated to 63%. And the abnormal responsiveness can be inhibited in presence of pretreatment with several new compounds which have been exhibited effective anti-HRV activity on cell lines. The results demonstrate that the established ASM model will be applied to screening the anti-HRVs drugs.

Objective:To explore the efficacy and safety of endoscopic esophageal varix ligation (EVL) combined with omeprazole and octreotide in the treatment of esophageal variceal bleeding.Methods:127 patients with cirrhosis complicated with esophageal variceal hemorrhage diagnosed and treated in our hospital from May 2014 to May 2016 were divided into the study group and the control group.The control group was treated with omeprazole and octreotide on the basis of conventional therapy,while the study group was treated with endoscopic esophageal variceal ligation (EVL) on the basis of control group.The clinical efficacy,hospitalization condition,incidence of adverse reactions and rebleeding rate after treatment of the two groups were analyzed.Results:All the patients in the study group were successfully operated.In the control group,10 patients showed hematemesis and melena,among which 1 patient wastreated with surgery.After treatment,the c lini cal effi cacy of the study group was superi or to the control group,and the di fference was stati sti cally significant (P＜0.05).During the treatment period,the hemostasis time,blood transfusion time,hospital stay and hospitalization expenses of the study gronp were significantly lower than those of the control group (P＜0.05).In the study group and the control group,10 cases and 7 cases respectively had nausea and vomiting,esophageal foreign body sensation,dizziness,palpitations,pain,bloating,increased facces frequency,fever and other adverse reactions,and the incidence of increased faeces frequency of control group was significantly higher than that of the study group (P＜0.05),but the incidence of other adverse reactions and the total incidence showed no significant difference between two groups (P＞0.05).The rate of rebl eeding was si gni fi cantly lower in the study group at 0.5,1,3,6 and 12 months after treatment than those in the control group(P＜0.05).Conclusion:Endoscopic ligation combined with omeprazole and octreotide was effective in the treatment of esophageal variceal bleeding,which could be effective,rapid hemostasis,reduce the hospital stay,hospitalization cost and rebleeding rate with high safety.

OBJECTIVE:To compare the effectiveness and safety of low-molecular-weight-heparin(LMWH)calcium and rivar-oxaban in preventing lower extremity deep venous thrombosis (DVT) in the elderly patients after surgery of replacement of frac-ture. METHODS:A total of 58 elderly patients underwent hip or artificial femoral head replacement were randomly divided into LMWH group (29 cases) and Rivaroxaban group (29 cases). All patients received basic prevention and physical prevention for DVT after surgery. Based on this,LMWH group was given Heparin calcium injection 4100 IU subcutaneously 10 h after surgery, for 10 d. Rivaroxabar group was given Rivaroxaban tablet 10 mg 10 h after surgery,once a day,for consecutive 10 d. The occur-rence of DVT and positive D-dimer were observed in 2 groups after surgery. The PT,APTT,TT,FIB and platelet counts abnormal-ity were also observed in 2 groups. RESULTS:There was no statistical significance in the incidence of DVT,the occarrence of pos-itive D-dimer,PT,APTT,TT,FIB and platelet counts abnormality 4,10 d after surgery between 2 groups(P>0.05). CONCLU-SIONS:LMWH and rivaroxaban both can be used for lower extremity DVT in the elderly patients after replacement of fracture sur-gery of and have similar therapeutic efficacy and safety.
