BACKGROUND:The hyperpoladzation-activated cyclic nucleotide-gated cation channel (HCN) gene is not increase the risk of induced cardiac arrhythmia,and can accept the modulation function of autonomic nervous system.Therefore,it is the first candidate gene for biological pacemakers.OBJECTIVE:To construct recombinant adenovirus vector containing human HCN4 gene and evaluate its transfection efficency in rat bone marrow mesenchymal stem cells (MSCs).DESIGN,TIME AND SETTING:The in vitro cytology-gene experiment was performed at the Lin Bai-xin Experimental Center,Second Hospital of Sun Yat-sen University from February to September 2008.MATERIALS:Ten SD rats were supplied by the experimental animal center of Sun Yat-sen University.Rlasmid pcDNA3.1-HCN4 containing target gene human HCN4,human embryo kidney 293 cells and Escherichia coll DH5α were preserved by our experimental center;Shuttle plasmid pShuttle-CMV containing green fluorescent protein gene and adenoviral backbone plasmid pAdxsi were bought from SinoGenoMax Co.,Ltd.METHODS:HCN4 cDNA segment was liberated from the cloning vector of pcDNA3.1-HCN4 via Hind Ⅲ+Xba Ⅰ,and subcloned into pShuttle-CMV,which was digested by I-Ceu Ⅰ +I-Sce Ⅰ double enzyme and subcloned into adenoviral plasmid to form recombinant adenovirus plasmid.Recombinant adenovirus plasmid was transfected into 293 cell lines by liposome,and the recombinant adenovirus AdHCN4 was packaged and transfected into rat MSCs.MAIN OUTCOME MEASURES:The identification of recombinant adenovirus plasmid vector,identification of recombinant adenovirus and its titration test;the transfection efficiency of recombinant adenovirus.RESULTS:Cloned sequence about 3.6kbp was obtained by Hind Ⅲ+Xho Ⅰ digestion after HCN4 cDNA segment was cloned into pShuttle-CMV.DNA sequencing results indicated that the clone location was correct.Recombinant adenovirus plasmid was cut into seven fragments while empty vector gained only six fragments after digested by Xho Ⅰ.The recombinant adenovirus was pathogenic to 293 cells after recombinant adenovirus plasmid was packaged in it.HCN4 cDNA (657bp) was amplified by PCR with virus titer of 2.5×10~(11) PFU/mL after transfected 293 cells with supematant.The efficiency of recombinant adenovirus infecting rat MSCs was about 90% when multiplicity of infection was 800.Rat MSCs expressed green fluorescence after transfection.CONCLUSION:The adenovirus vector with human HCN4 cDNA was established successfully,which can effectively transfect rat MSCs.

Objective To investigate the effect factors for language and memory dominance testing in propofol Wada test in refractory epilepsy patients.Methods From January 2010 to August 2013,total of 23 patients underwent propofol Wada tests for language and memory dominance evaluation.According the performance in language test and memory test,the patients were divided into two groups,respectively:succeed with test or failed in test.The relevant factors including age,duration of epilepsy,handedness,FIQ (full scale of intelligence quotient),lateralization of lesions,language dominance,dose of propofol and the adverse effects of propofol were recorded as independent variables.Logistic regression was adopted to screen the effect factors for memory dominance evaluation.All statistical analyses were processed with SPSS software.Results All 23 patients succeeded with language test,but only 13 patients succeed with memory test.The difference of success ratios between language test and memory test was significant (P=0.001).For memory test,the difference of duration of epilepsy and FIQ in success group and failed group was significantly different (duration of epilepsy:(10.57±4.68) vs (18.30±9.30),P=0.032,FIQ:(81 ±25.33) vs (64.2±10.86),P=0.046).More grade Ⅱ adverse effects of propofol occured in the patients who failed in memory test (P=0.011).Logistic regression results indicated the grade Ⅱ adverse effects of propofol were the main risk factor for memory test failure (OR=28.0,P＜0.01).Conclusions Propofol Wada test is an effective method for language dominance evaluation.However,the effect factors for memory dominance evaluation are much more than language evaluation,such as duration of epilepsy,FIQ and grade Ⅱ adverse effects of propofol,and grade Ⅱ adverse effects of propofol may be the most significant risk factor.

OBJECTIVE To understand the situation of the nosocomial infection among the hospital inpatients in a grade-A hospital in Beijing.METHODS Surveillance on nosocomial infection was performed among the hospital inpatients from Jan 2005 to Dec 2007.RESULTS From Sept 2006 to Aug 2007,803 cases were infected,the incidence was 1.99%.The lower respiratory tract ranked the first place(38.97%)and the highest infected rate was in ICU(16.16%).The species were predominated by Gram-negatives.The main pathogenic microorganisms were Pseudomonas aeruginosa,Staphylococcus aureus,Escherichia coli,Acinetobacter baumannii,Klebsiella pneumoniae and Candida albicans,etc.From 2005 to 2007,the infections caused by P.aeruginosa increased gradually,and the infections caused by C.albicans reduced gradually.CONCLUSIONS Many people should work to prevent and control the infections in hospital,such as doctors,nurses,inpatients,management workers,etc.

Objective To explore the interaction of streptococcus suis serotype 2 recombinant suilysin ( SLY ) with platelets, and provide the theoretical basis for clinic treatment of patients infected with S.suis.Methods The nickel column affinity chromatography was used to purify the recombinant SLY.The hemolytic acivity was identified by optical density before the platelets aggregation induced by a SLY was detected by a platelet aggregometer or electron microscope and the effect of aspirin on platelets aggregation was analyzed.The impact of wild type 05ZYH33 and sly-deficient mutant strainΔSLY on platelets of mice was compared to predict the interaction of the SLY with platelets in vivo.Results and Conclusion Hemolytic activity of recombinant SLY was 2000 hemolytic units( HU) and platelets aggregation was induced at 1 μg/ml.The aggregation can be inhibited by aspirin in 5 mmol/L.SLY can also increase the volume and reduce the amount of platelets in mice.
