The effect of tumor necrosis factor (TNF) in combination with thymosin and chemotherapy on advanced primary liver cancer was observed. Eighty-nine advanced primary liver cancer cases were randomized into two groups: Patients in the control group were treated only with chemotheraputic drugs, and patients in the observing group were treated with TNF, thymosin and chemotheraputic drugs. The results showed that there were higher primary tumor regression rates and statistically reduced AFP in the observing group than control group. The rate of half year survival, one year survival and two years survival improved 28.6%, 18.0% and 5.1% than those of control group, respectively. We belived that this combined therapy could effectivelly improve the patients immunity, the quality of survival, and long the patients survival period.

BACKGROUND: Studies have demonstrated that intervention material retention for a period of time in vivo causes pathogenic bacteria surface attachment, proliferation even forming biofilm to become potential source of high polymer catheter-associated infection. Inhibition of biofilm formation significantly reduces infection.OBJECTIVE: To evaluate the antimicrobial effect of anti-infective polyethylene material and its inhibiting effect to biofilm on the surface.DESIGN, TIME AND SETTING: Single sample observation was performed at the National Engineering Research Center for Engineering Plastics, Technical Institute of Physics and Chemistry, Chinese Academy of Sciences from June 2008 to May 2009, and the antimicrobial test was performed at the General Hospital of General Staff Headquarters of PLA in March 2009.MATERIALS: Organic antibacterial agent2,4,4'-trichloro-2'-hydroxydiphenyl ether; IONPURE~(R) Silver-Inorganic anti-microbialreagent; low-density polyethylene (LDPE).METHODS: LDPE was respectively blended with organic antibacterial agent and inorganic antibacterial agent, and the LDPE slice was prepared by injection molding process.MAIN OUTCOME MEASURES: The antimicrobial efficacy of anti-infective polyethylene was determined by the plate counting method. The ultrasonic-plate method and scanning electron microscopy were introduced to observe the biofilm formation.biofilm maturation. The propagation of microbe was found to be depressed remarkably on the surfaces of modified samples with organic antibacterial agent, and the formation of biofilm was prevented. The observation of SEM confirmed that no biofilm was formed on the surfaces of PE added organic antibacterial agent. The results showed that a large amount of bacteria and extracellularpolysaccharide matrix adhered on the surfaces of PE added inorganic antibacterial agent and untreated PE.CONCLUSION: Anti-infective polyethylene added organic antibacterial agent possesses excellent antimicrobial performance against S. aureus and E coli, and it can inhibit the formation of biofilm on the surfaces, which provides a promising approach to prevent catheter-related infections.

Objective To study the role of human carcinoembryonic antigen-related cellular adhesion molecule 1 (hCEACAM1)in mediating the specific adhesion of N. gonorrhoeae to its human host cells.Methods A recombinant eukaryotic expression vector pCDPGICEA1 was constructed by putting hCEACAM1 cDNA behind both hCD46 promoter and rabbit β-globulin intron 2,and with which,the COS-1 cells were transfected. Following G418 selection, the COS-1 cells expressing hCEACAM1 were sorted out with flow cytometry. The adhesion of N. gonorrhoeae to the gene transfected COS-1 cells was analyzed with bacterial binding assay. Results hCEACAM1 cDNA could be expressed effectively under the direction of hCD46 promoter and rabbit β-globulin intron 2,and N. gonorrhoeae could adhere to COS-1 cells expressing hCEACAM1. Conclusion hCEACAM1 can mediate the adhesion of N. gonorrhoeae to animal originated COS-1 cells. thus its transgenic mice may be used as a novel animal model for studying N. gonorrhoeae infection.

OBJECTIVE To study the antimicrobial activity of antimicrobial plastics and its depressing effect to biofilm on the plastics′s surface. METHODS Test tube dilution method was adopted to study the antimicrobial activity and spectrum of antimicrobial plastics. Plate live bacterial recording method and scanning electron microscope(SEM) were introduced to study the formation of biofilm. RESULTS Wide inhibiting spectrum to pathogenic microbe such as Pseudomonas aeruginosa,Staphylococcus aureus,and Escherichia coli was confirmed,and the biofilm was formed after four stages,ie deposit,adhesion,propagation and biofilm formation,and propagation of microbe was found to be inhibited greatly in the surface of antimicrobial plastics,so that the formation of biofilm in the surface of antimicrobial plastics was held back,and the observation of SEM also confirmed that no biofilm was formed in the antimicrobial plastics′s surface. CONCLUSIONS Antimicrobial plastics could inhibit pathogenic microbe remarkably with wide inhibiting spectrum,and it could also depress the formation of biofilm in the surface,which indicated that it is a promising approach to prevent catheter related infections by adopting antimicrobial catheters.
