Objective　To construct an anti-LPS single chain phage antibody library in mice for further biomedical works. Methods　Total RNA was extracted from splenic cells for reverse transcription after BALB/C mice had been immunized with pure LPS for 4 weeks. The designed primers were used to amplify the variable region genes of both heavy and light chain (VH,VL) with polymerase chain reaction. The VH and VL were then conjugated to form a single chain of variable fragment (ScFv) by a linker. The ScFv was cut by NotⅠ and SfiⅠ and then ligated into a pCANTAB5E phagemid vector which was digested with the same restriction enzymes. The ligated vector was then tranfected into the competent E.coli TG1 cells. Four TG1 clones were randomly selected to detect the exotic DNA. Results　The titer of anti-LPS in murine sera was 1∶12 800. The concentration of total RNA was 12.3813 μg/ml. The length of the fragments were 340 bp for VH, 320 bp for VL and 800 bp for ScFv respectively. 1.9×107 clones were grown after transfection and one from the four randomly selected clones was identified to contain the exotic DNA. Conclusion　A 4.75×106 murine anti-LPS single chain phage antibody library was successfully constructed.

Objective To evaluate the safety and feasibility of ketamine-propofol mixture anesthesia for 85 children with congenital heart disease undergoing cardiac catheterization.Methods Eighty-five children with congenital heart disease undergoing cardiac cathete-rization were randomly divided into ketamine group(K group,n=44)and ketamin-propofol group(KP group,n=41).K group:1 mg?kg-1 ketamine was injected intravenously and then infused at 50 ?g?kg-1?min-1 for anesthesia maintenance.KP group:anesthesia was induced with ketamine 1 mg?kg-1 and propofol 1 mg?kg-1 intravenously,and maintained by continuous infusion of ketamine(16.7 ?g?kg-1?min-1)and propofol(33.3 ?g?kg-1?min-1).Electrocardiogram,blood pressure,pluse,respiratory frequency,saturation of blood oxygen were continously monitored.Results Hemodynamic and respiratory function were stable in both 2 groups.Ketamine consumption in K group was significantly more than that in KP group[(52.1?2.8)?g?kg-1?min-1 vs(25.3?7.3)?g?kg-1?min-1],eye opening time and recovery time were also longer in K group than those in KP group [(50.2?16.5)min vs(40.4?18.3)min].Conclusion The ketamine-propofol mixture was a safe,efficacy anesthesia with excellent recovery in children with congenital heart disease undergoing cardiac catheterization.

Objective To explore an algorithm to define the threshold value for tumor contouring on 18F-fluorodexyglucose (FDG) PET imaging. Methods A National Electrical Manufacturing Association (NEMA)NU 2 1994 PET phantom with 5 spheres of different diameters were filled with 18F-FDG. Seven different sphere-to-background ratios were obtained and the phantom was scanned by Discovery LS 4. For each sphere-to-background ratio, the maximum standardized uptake value ( SUVmax ) of each sphere, the SUV of the border of each sphere ( SUVborder ), the mean SUV of a 1 cm region of background (SUVbg) and the diameter (D) of each sphere were measured. SPSS 13.0 software was used for curve fitting and regression analysis to obtain the threshold algorithm. The calculated thresholds were applied to delineate 29 pathologically confirmed lung cancer lesions on PET images and the obtained volumes were compared with the volumes contoured on CT images in lung window. Results The algorithm for defining contour threshold is TH% = 33.1% + 46.8% SUVbg/SUVmax + 13.9%/D ( r = 0.994) by phantom studies. For 29 lung cancer lesions, the average gross tumor volumes ( GTV ) delineated on PET and CT are ( 7.36 ± 1.62 ) ml and (8.31 ±2.05) ml, respectively (t = -1.26, P＞0.05). Conclusion The proposed threshold algorithm for tumor contouring on PET image could provide comparable GTV with CT.
