AIM: To explore the effects of axial stress regulation on healing of lengthened ca llus. METHODS: Tibiofibulars of 30 rabbits were lengthened 2 cm with t wice plane sreminobicular crib external fixator. Experimental group continues to lengthen 3 mm, and then were drawn and shortened 0.5mm once every 24 h separate ly for 10 days. Ten days later, tibiofibulars were axial short-stressed 1 mm wee kly with three times. Animals were killed 58 days after operation and X-ray, bon e density and histology tests were performed with lengthened bone. RESULTS: X-ray examination had no significant difference between two group animal when le ngthen ended, but X-ray showed lengthened callus was different on day 58. In con trol group, lengthened center had a serial callus and cortex had no formed, in experimental group, lengthened center had serial cortex and transfixial medullar y cavity expect serial callus. Bone density tests with two-energetic X-ray bone density measuring device showed bone density was higher in experimental group th an control group (P

Objective:To investigate the effect and safety of Jinweitai combined with triple therapy in the treatment of gastric ul-cer. Methods:Totally 140 cases of gastric ulcer patients were randomly divided into two groups, group A was given clarithromycin, amoxicillin, bismuth pectin and pantoprazole in Hp eradication triple therapy, while group B was additionally given 0. 3g Jinweitai oral-ly, po,tid. The treatment course was 8 weeks. The effect was observed and compared. Results:Both the total effective rate and Hp e-radication rate of group B were higher than those of group A, the rate of mild inflammation and non-neutrophils infiltration after the treatment in group B were higher than those in group A (P<0. 05). The incidence of adverse reactions in the two groups was without statistical significance (P>0. 05). Conclusion:Base on the conventional Hp eradication triple therapy, Jinweitai can increase Hp e-radication rate and promote inflammation eliminate without extra adverse reactions in the treatment of gastric ulcer.

Objective: To study the correlation between the serum chemokine CXC Ligand 16 (CXCL16) levels or the CXCL16 gene rs3744700 polymorphisms and TOAST subtypes in patients with acute cerebral infarction. Methods: A total of 248 patients with atherosclerotic cerebral infarction within 7 days after symptom onset were selected, among them 149 patients were in a large artery atherosclerotic (LAA) cerebral infarction group, and 99 patients were in a small arterial occlusive (SAO) cerebral infarction group. The polymerase chain reaction (PCR) and gene sequencing were used to detect the genotypes. An enzyme-linked immunosorbent assay was used to detect the serum CXCL16 levels. Results: Circled digit oneSerum CXCL16 level in the LAA cerebral infarction group was 2.5 ± 0.3 μm/L and in the SAO cerebral infarction group were 2.3 ± 0.6 μg/L (P<0.01). Circled digit twoAmong the 149 patients in the LAA cerebral infarction group, the GG genotype frequency at polymorphic loci of CXCL16 gene rs3744700 was 91.9% (137/149) and the G allele frequency was 96.0% (286/298). They were higher than 81.8% and 89.9% in the SAO cerebral infarction group. There were significant differences (P < 0.05). Circled digit threeThe serum CXCL16 level in patients with CG genotype was 2.5 ± 0.3 μg/L in the LAA cerebral infarction group, ant it was higher than 2.1 ± 0.3 μg/L in patients with GT + TT genotype; the serum CXCL16 level in patients with CG genotype was 2.4 ± 0.6 μg/L in the SAO cerebral infarction group, and it was higher than 2.1 ± 0.3 μg/L in patients with GT + TT 2 genotype (all P < 0.01). Among the patients with GG genotype, the serum CXCL16 level in the LAA cerebral infarction group was higher than that in the SAO cerebral infarction group (P = 0.01); there was no significant difference in patients with GT + TT genotype between both groups. Circled digit fourMultivariate Logistic regression analysis showed that the serum CXCL16 level (OR =0.37, 95% CI 0.19 -0.70) and the GG genotype at polymorphic loci of CXCL16 gene rs3744700 (OR =2.57, 95% CI 1.23 -5.36) were the independent risk factors for affecting LAA cerebral infarction. Conclusion: In the TOAST subtypes, the correlation of serum CXCL16 level and the GG genotype at polymorphic loci of CXCL16 gene rs3744700 and LAA cerebral infarction are higher than SAO cerebral infarction.

ObjectiveTo investigate the effect of hyperbric oxygen (HBO) on infarct volume and relevant mechanism after permanent focal cerebral ischemia in adult rats.MethodsRat model of focal cerebral ischemia induced by intraluminal filament occlusion of middle cerebral artery (MCA) was used. HBO(2.0 ATA) was applied to HBO group. Infarct volume, matrix metalloproteinase 2 (MMP-2) and MMP-9 were detected at 6h, 24h, 48h, 72h,120h and 10d after ischemia.ResultsThe infarct volume obviously decreased at 120h and 10d and expression of MMP-9 lowered at 48—120h in HBO groups. There was no significant change in MMP-2.Conclusion HBO can reduce infarct volume after cerebral ischemia, which may be related to downregulation of MMP-9 levels.

Objective To develop a new methodology of prenatal sonography scoring to assess and dignose clubfoot.Methods Thirty-one fetuses suspected clubfoot(50 foots) and 62 normal fetuses(124 foots) were scanned with both 2D and 3D sonography,and were divided into normal feet group and clubfeet group.Our scoring system was made according to the Pirani-scoring for children,while considering the morphology of mid-foot and hind-foot of infants.The doctors would give final diagnosis for all fetuses after delivery or induced labor,and analyse the correlations among the abnormal signs,sonographic score and the clinical outcomes.Results The curve lat border,the medial crease,the empty heel and the post crease can be observed in the 3D reconstruction images.These four abnormal signs had close correlations with the clinical results.Conclusions The new prenatal clubfeet scoring system by 3D sonography is a promising methodology with clinical values.

Objective To investigate epidemiological characteristics in hospitalized adolescents and children who suffered from traffic injuries,such as source and location of an accident,the victim's gender arid age,and the site of injury.Methods The chosen subjects were 163 hospitalized children aged 1 to 18 years old,who were admitted to general hospitals in Shanghai in the years of 2004 to 2005 as a result of traffic injuries.Descriptive statistics and analysis were used to interpret the data.Results Children of immigrant workers and suburban residents were the main victims ;the main cause of injury was the collision between the motor vehicle and the pedestrian;this type of traffic injury was the most prevalent among children between 5 to 9 years old;and the locations of the injury was most commonly found in the head,the face, and the extremities.Conclusions From this statistical evidence,it could be concluded that it would be worthwhile for the government to pay more attention to children of immigrants and suburban residents to effectively educate them about traffic safety and knowledge,tt is also advisable to improve the safety protection and post - traffic injury care of children passengers.

Objective To perform comparative proteomic analysis of human ovarian cancer cell lines for detecting platinum-resistance associated proteins.Methods The total proteins of two sensitive (SKOV3 and A2780)and four resistant(SKOV3/CDDP,SKOV3/CBP,A2780/CDDP and A2780/CBP) human ovarian cancer cell lines were separated by two-dimensional gel electrophoresis(2-DE).The differentially expressed proteins were analyzed using image analysis software,stained with Coomassie Brilliant Blue,then identified using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry(MALDI-TOF-MS)and database searching.The mRNA and protein levels of the differentially expressed protein which was most significant in all of the four resistant cell lines were validated by RT-PCR and western blotting,respectively.Results Five proteins were found to be significant in four cell lines. Annexin A3 and destrin were up-regulated and nicotinamide-adenine dinucleotide phosphate(NADP)- dependent isocitrate dehydrogenase 1 was down-regulated in all the four resistant samples.Glutathione transferase omega 1 had an increased expression in the other three resistant cell lines except for SKOV3/CBP in which its expression was not changed.However,cofilin 1 represented a different trend.In the two resistant sublines of SKOV3,eofilin 1 had a down-regulation,but it had an up-regulation in the cell lines induced from SKOV3.The expression of annexin A3 was up-regulated by 3-20 fold and the results of RT- PCR and western blotting showed complete consistency with that by 2-DE.Conclusions Proteomic techniques are useful to the identification of the resistance-associated proteins in ovarian cancer platinum- resistant cell lines and five candidates have been found.The five differential proteins might become hopeful candidate biomarkers for resistance.
