Objective To observe the effects of the Ossatron high-energy shock waves on bone nonunion and delayed union.Methods Between October 2004 and October 2005,18 patients with nonunion and four patients with delayed union were treated with high-energy extracorporeal shock wave therapy(Ossatron,HMT Co., Swiss).Facture lines were located with C-arm X-ray before treatment.Parameters of shock waves were decided according to fracture sites.Patients with unstable fixation received plaster or bracing for 6 to 8 weeks after treatment. After therapy,follow-up radiography was performed at 6 and 12 weeks and monthly afterwards until the fracture united. Results The mean follow-up was 6.7 months(range,3 to 12 months).There were no complications except local petechial hemorrhage and local swelling in 10 patients.Thirteen patients(59.1%)got bony union,including 12 patients(66.7% )with stable internal fixation,and the average healing time was 4.3 months(range,6 weeks to 6 months).Nine fractures(40.9%)still suffered nonunion.Conclusion High-energy shock waves are a good alternative therapy for nonunion and delayed union,with obvious advantages of being non-invasive and safe.

Objective To study the mutations of outer-membrane porin gerte (oprD) in imipenem-resistant Pseudomonas aeruginosa.Methods The PCR was applied to detect the oprD gene from the 34 clinical imipenem-resistant Pseudomonas aeruginosa.DNA sequence was proceeded to analysis the nuclentide sequence of the oprD gene and the deduced amino acid sequence.To analysis the mutation and the function of the oprD domain,those mutations were compaired with the standard Pseudomonas aeruginosa ATCC27853 and 2 clinical imipenem-susceptibility isolates.Results oprD gene mutation was wide and diverse.The rate of the mutation was 92.3% (12/13),mutations were concluded dot mutation,deletion mutation and insert mutation,those result in the amino sequence change and frame shift in L2 and L3 loops of outer membrane protein D,hampering the combine of oprD and imipenem.Some new mutations were found.They were 1 079,1 114,1 196,1 206,1 288,1 300,1 301 bases and 115,127,154,158,185,189 aminos.All above mutations were not deteced in ATCC 27853 and 2 clinical imipenem-susoeptibility isolates.Conclusions The wide and diverse mutations in oprD gene result in amino acid change and/or frame shift L2 and L3 loops,hampering the binding of IMP and oprD.Those may result in resistance to imipenem in Pseudomonas aeruginosa.

Methods A total of 189 con?secutive AMI young patients(age≤44 years)who underwent coronary angiography were retrospectively retrieved from the database.Those patients with AMI were divided into Hui group(46 cases)and Han group(143 cases). The clinical features and results of coronary angiogram were com?pared between the two group. Results Compared with Han group,Hui group are more younger than Han group,high prevalence rate of diabetes, lower smoking history and lower drinking history(P<0.05). Coronary angiography showed the incidence of three?vessel lesions was significant low?er in Han group than in Hui group(P<0.05). Both group showed single vessel was the most common lesion. Conclusion Hui nationality patients with acute myocardial infraction are more younger and are are more prone to suffering from diabetes history、lower smoking history and lower drinking history than Han nationality patients. The coronary artery lesions of Hui nationality patients with acute acute myocardial infraction are more three?branch lesions than Han nationality patients.

OBJECTIVETo screen the learning and memory mutant from N-ethyl-N-nitrosourea (ENU) mutagenic zebrafish F1, and to get the new model animal to study the mechanism of learning and memory.

METHODSZebrafish mutant was screened by inhibitory avoidance behavioral test and identified by the expression of gene c-fos with qRT-PCR.

RESULTSWe isolated a zebrafish mutant related to learning and memory, fgt. In this fgt zebrafish mutant long-term memory was much lower than that in wild-type when tested at 24 h after training. The 24 h long-term memory in about half of fgt mutant F2 (13/30) were significantly lower than those in wild-type, and the others relatively normal. Compared with the expression in wild-type fishes, the expression of immediate-early genes (IEGs) c-fos in half of fgt mutant F2 (13/30) after exploring in a novel environment increased distinctly from the basal control levels statistically, and the others relatively normal, which were in accordance with the behavioral results.

CONCLUSIONThe zebrafish mutant fgt is a dominant mutant with defect in long-term memory.

Background and purpose:Cyclooxygenase-2 (Cyclooxygenase-2,COX-2) is an important rate-limiting enzyme that is responsible for transformation of arachidonic acid into prostaglandins(PGs).Although Helicobacter pylori(Hp) infection-induced gastric over-expression of COX-2 (COX-2) is an important factor of gastric cancer,the mechanism of COX-2 expression in gastric mucosa cells infected with Hp is still not clear.Our study was to reveal the effect of Hp on expression of COX-2(cyclooxygenase-2),the impact of p38MAPK signaling pathway in human gastric epithelial cancer cells line MKN45,and to investigate the potential mechanisms of expression of COX-2. Methods:The expression of COX-2 mRNA infection by standard Hp NCTC11637 in human gastric epithelial cancer cells line MKN45 was evaluated by real-time fluorogenic quantitative polymerase chain reaction (RFQ-PCR).The effect of infection by Hp on COX-2 expression,activation of p38MAPK and its downstream of the ATF-2 was assayed by Western blot.Results:The expression of COX-2 mRNA in MKN45 cells infected by Hp compared with control group,COX-2 mRNA had 3 fold,7.2 fold,5.1 fold,4.3 fold up-regulation after 3 hrs,6 hrs,9 hrs,12 hrs,respectively. COX-2 mRNA expression in each time group was significantly higher than that in the control group(P
