AIM: Screening of phage antibodies against HBsAg from the constructed phage display library and sequencing of the positive clones.METHODS: RNAs were extracted from blood lymphocytes of a HBsAg-immunized volunteer. Then cDNAs were synthesized by RT-PCR. To construct the phage antibody display library, cDNAs of Fd fragments and ? chains of the antibodies were amplified through PCR and were inserted into vector pComb3H. Three rounds panning against coated HBsAg showed the specific enrichment of phage antibody. Positive clones were selected and sequenced.RESULTS: A phage antibody display library was constructed after amplifing of Fd fragments and ? chains of IgG1. Three Fab antibodies from the library were selected and sequenced. The result of sequencing showed that two of the three antibodies had the same Fd fragment and all of the three had the same light chain. CONCLUSION: The phage antibody display library was constructed successfully and three specific antibodies (Fab fragments) have been obtained from it.

OBJECTIVE To strengthen the management of earthquake victims with nosocomial infection,in order to prevent and control the multidrug-resistance transmission,and the nosocomial infection outbreak. METHODS All 77 earthquake victims were under real-time monitoring. RESULTS Of 77 cases,53 were infected (69.74%). From 83 samples,83 pathogenic bacteria were isolated. The Gram-positive cocci were 19 (meticillin-resistant Staphylococcus aureus 3,Meticillin-resistant S. epidermidis 7),58 were Gram-negative bacilli (Acinetobacter baumannii 21,multi-drug resistant strains 10,ESBLs positive Escherichia coli 10,Pseudomonas aeruginosa 9) and the fungi were 6 strains,The resistance rates of Gram-positive cocci to penicillin,ampicillin/sulbactam and cefazolin were 89.47%,68.42% and 89.47%; the resistance rates of Gram-negative bacillis to imipenem,cefoperazone/sulbactam,piperacillin/tazobactam,azithromycin,tobramycin,and cefoxitin were 37.93%,60.34%,48.83%,98.28%,98.28% and 70.69%,respectively. CONCLUSIONS Under the situation of higher infection rate and a serious drug resistance in earthquake area,there are no multidrug-resistance transmissionm and the spread of nosocomiol infection outbreak happened in hospital due to strictly enforced prevention meassures and access real-time monitoring and management,

Objective To examine the effect of fibronectin connecting segment-1 (CS1) peptidefacilitated blockade of inflammatory cells-fibronectin adhesion on a rat liver transplantation model of prolonged ex vivo cold ischemia.Methods A model of liver transplantation in Wistar→Wistar rat was established.The donors of the CS1 treatment group received CS1 peptides through the tail vein for 3 days before operation.Another two doses of CS1 peptides were administered into the liver intraportally during procurement and before transplantion.Recipients received an additional 3-day course of CS1 peptides after transplantation.Rats in control group received scrambled peptides.Rats were sacrificed at 6,24 and 72 h after transplantion,and plasma transaminase activity and hepatic pathological changes were studied.The inflammatory cells and liver sinusoidal endothelial cells were visualized histochemically.Real-time PCR was used to detect tumor necrosis factor-α (TNF-α),interleukin-1β (IL-1β) and vascular endothelial growth factor (VEGF) mRNA expression in the liver.Results The plasma transaminase activity and hepatic necrosis areas in CS1 treatment group were significantly lower than in control group (P＜0.05).CS1 peptides treatment significantly decreased the number of Kupffer cells after transplantation and greatly inhibited the recruitment of neutrophils to the graft liver as compared with control group (P＜0.05).After prolonged cold ischemia,only a few hepatic endothelial cells exhibited positive staining of hepatic sinusoidal endothelial cell biomarker SE-1.Lots of hepatic sinusoidal endothelial cells positive for SE-1 staining could be detected in CS1 group at 72 h after transplantation,while much less SE-1 positive cells presented in the control goup.Prolonged cold ischemia caused a significant increase of TNF-α,IL-1β and VEGF mRNA expression in the graft liver of control group after transplantation.The expression of TNF-α mRNA at 6 and 24 h and VEGF mRNA expression at 24 h were significantly lower in CS1 group than in control group (P＜0.05).Conclusion Peptide-mediated blockade of inflammatory cells-fibronectin interaction decreased the mRNA expression of inflammatory cytokines,prevented hepatic sinusoidal endothelial cells from injury and subsequently protected against severe ischemia/reperfusion injury of the graft liver after transplantation.

Objective:This study aimed to explore the Ventromedial Hypothalamic Orexin-1 and Orexin-1 Receptors in Regulation of Gastric Acid Secretion in Conscious Rats.Methods:Rats were anaesthetized and fitted with a stainless steel carmula placed just above the VMH or paracele,after random allocation orexin-A,[Pro34]-peptide YY and [CPP1-7,NPY19-23,Ala31,Aib32,Gln34] -pancreatic polypeptide were injected in the VMH;SB-334867 was intraperitoneal injection;atropine was subcutaneous injection;GR-231118 and CGP-71683 were injected in the paracele.Using pyloric ligation model,tests the effect of different drugs on rat gastric acid secretion and gastric juice volume.Results:OXA induced dose-dependent increase of gastric acid secretion;SB-334867 induced dose-dependent inhibition of gastric acid secretion.The stimulatory effect of OXA on acid secretion was inhibited by SB-334867;atropine induced dose-dependent increase of gastric acid secretion and block the effect of orexin-A on gastric acid secretion;the gastric acid secretion was inhibited by GR-231118 or CGP-71683,and GR-231118 or CGP-71683 were blocked the effect of orexin-A on gastric acid secretion;Intraventromedial hypothalamic injections of [CPP1-7,NPY19-23,Ala31,Aib32,Gln34]-pancreatic polypeptide increased gastric acid secretion.Conclusion:It is suggested that endogenous orexin-A acts on the ventromedial hypothalamus to stimulates acid secretion.This stimulatory effect is probably mediated through orexin receptor,Y1 and Y5 receptor,and the vagus nerve system.

Objective To investigate the effects of penehyclidine hydrochloride combined with ulinastatin on postoperative cognitive function in the patients undergoing thoracic surgery.Methods One hundred and twenty patients undergoing lung cancer thoracotomic radical resection were randomly divided into hydrochloride penehyclidine composite ulinastatin group(HU group),hydrochloride penehyclidine group(H group),ulinastatin group(U group)and control group(C group).The arterial blood was collected for detecting OI,TNF-α,IL-6 and IL-8.The serum levels of S-100β and NSE were detected.The MMSE scores were evaluated.Results Compared with the H group and U group,the levels of TNF-α at T3-4 in the HU group were decreased,and the levels of IL-6 and IL-8 at T2-4 were decreased,while OI was increased(P＜0.05).Compared with the H group and U group,the serum levels of S-100β and NSE at T5-8 in the HU group were decreased(P＜0.05);compared with the H group and U group,the MMSE scores at T6-7 in the HU group were increased(P＜0.05).Conclusion Penehyclidine hydrochloride combined with ulinastatin could reduce the inflammation reaction during one lung ventilation in thoractomy and improves the postoperative cognitive function.

Objective To investigate the therapeutic effect of ciprofloxacin (Cipro) conjugated with 11 poly-arginine peptide (R11) on rabbit model with bacterial cystitis (BC). Methods 50 New Zealand rabbits of 4-month old were chosen to establish the models and evenly divided into 5 groups randomly : Group A: normal control; Group B: intravesical instillation (II) of R11; Group C: II of Cipro; Group D: II of R11-Cipro; Group E: intravenous injection of Cipro. Several parameters were observed which included: urinary frequency, positive rate of urine culture, histopathological analysis of cystitis stained with hematoxylin and eosin. Results Severe inflammatory responses and massive infiltration of inflammatory cells were observed after the models were established. R11-Cipro group was better than intravenous injection of Cipro group in treating cystitis (P < 0.05). R11-Cipro group was better than the other four groups in urinary frequency and urine culture. Conclusions Intravesical instillation of R11-Cipro demonstrated significant therapeutic effect on bacterial cystitis. R11 , as an efficient vector, could deliver specific antibiotics to bladder mucosa precisely and function well locally.
