Objective To analyze the X -ray, CT, and MR imaging findings in osteoid osteoma. Methods Forty-eight cases of osteoid osteoma proved by surgical pathology were collected, including 33 males and 15 females. Among the 48 cases, all patients had plane films, 32 were imaged with CT scanning, 10 with MR imaging, and 8 with all three techniques. The imaging findings of osteoid osteoma and the ability of X-ray, CT, and MRI in demonstrating the nidus and the surrounding reaction were analyzed. Results The imaging manifestations of osteoid osteoma revealed a circular or oval nidus with different bone sclerosis around the nidus. The diameters ranged from 0.4 cm to 1.7 cm, with the average of 9.7 cm. There were also soft tissue and bone morrow edema around the nidus or distinct effusion of joint on MR imaging in all 10 cases. Among 48 cases, only 37 cases showed nidus on plane film. All 32 cases with CT scanning showed nidus. The display ratios of nidus were 77% for X-ray and 100% for CT, respectively. 10 cases with MR imaging could be diagnosed correctly. But the nidus could be affirmed in only 8 cases, and the nidus was affirmed by comparing with plane film or CT in the other 2 cases. Conclusion Nidus is the key in diagnosing the osteoid osteoma correctly. Plane film is still an important checking method for osteoid osteoma. CT scan is the best method to demonstrate the nidus. MRI can demonstrate the soft tissue and bone morrow edema around the nidus sensitively, but probably lead to an incorrect diagnosis. Combining with X-ray or CT, MRI can make an accurate diagnosis.

Background:Helicobacter pylori(Hp)is an important pathogen for peptic ulcer and gastric cancer,and is reportedly associated with a variety of extragastrointestinal diseases. However,there is no body fluid detection technique for Hp infection in clinical practice. Aims:To identify Hp infection-associated differentially expressed proteins in urine with relative molecular mass more than 10 kDa and provide potential biomarkers for diagnosis of Hp infection through body fluid detection. Methods:Midstream urine was collected from volunteers in the morning,and 13 C-urea breath test was performed to determine Hp infection. Each of 15 Hp-negative and 15 Hp-positive urine samples were mixed respectively for protein extraction. Spectra data were acquired by high performance liquid chromatogram-mass spectrometry,and label-free technology was used for relative quantitative analysis. The other 26 urine samples(15 Hp-negative and 11 Hp-positive) were used for validation by full scan. IPA software was employed for bioinformatics analysis. Results:A total of 475 urinary proteins were detected by label-free quantitative analysis and 42 differentially expressed proteins were identified. Finally,11 significantly up-regulated differentially expressed proteins were confirmed by external scanning validation. Bioinformatics analysis revealed the molecular functions,biological pathways,and related diseases of these differentially expressed proteins. Conclusions:These 11 differentially expressed proteins more than 10 kDa identified in urine might be potential biomarkers for diagnosis of Hp infection and provide molecular evidence for the correlation of Hp infection with extragastrointestinal diseases.

In order to assess the cytotoxin effect of Campylobacter jejuni (C.jejuni), the whole cell lysates from 9 strains of Guillan-Barre Syndrome (GBS)- associated C.jejuni and 4 strains of diarrhea-associated C. jejuni were co-cultivated with HeLa cells at the concentration of 0.001-5.00 μg/mL in vitro. The morphologic change of HeLa cells was observed under Olympus BX51 microscope after treatment with different concentration of bacteria lysate in the following 4 days. The morphological changes including swelling, irregularity and lysis of the affected cells over 50% was selected as the cut off for positive change and C.jejuni 81-176 and Helicobacter J99 strains were chosen as the positive and negative control. It was found that the minimum concentration to induce the positive changes in 10 strains(8 GBS associated and 2 strains from diarrhea patients)was 0.1μg/mL and 1 strain with the positive change at the minimum concentration of 1 μg/mL. There was only one GBS-associated strain causing no morphologic change on HeLa cells at the concentration of 5 μg/mL. It was evident that the cytotoxic effect of C.jejuni strains on HeLa cell was strain-specific, and there was no significant difference in the cytotoxic effect on HeLa cell between GBS-associated and diarrhea associated C.jejuni strains.

BACKGROUND: There are various methods for management of allogeneic bone, xenogeneic bone and various tissue engineered materials, but there is no ideal method for treatment of insufficient bone mass following jaw defects. OBJECTIVE: To observe the repair efficiency of bone composite and biomembrane following large mandibular defect and mandibular defect combined with tooth luxation in animal studies. DESIGN, TIME AND SETTING: The controlled observational animal study was performed at the Animal Laboratory of Zhejiang University from March to July 2006. MATERIALS: The mixed proportion of Bio-oss material and autologous bone powder was 1:1. The proportion of recombinant human bone morphogenetic protein-2 freeze-dry powder dissolved in autologous fresh blood was 0.25 mg:1 mL. Bone powder mixture was moistened by blood containing human bone morphogenetic protein to stick on the medicine spoon for moulding easily. METHODS: Ten New Zealand rabbits were selected. Consecutive bone defects (15 mm×6 mm×5 mm) were made in the inferior border of bilateral mandible body. Bone composite and Bio-gide membrane were randomly implanted into one side (bone composite + Bio-gide membrane group). Another side was directly sutured as blank control group. The remaining 30 rabbits were considered bone composite + Bio-gide membrane + implantation tooth group. A bone defect (15 mm×6 mm×8 mm) was made at the upper site of inferior border of mandible, with the combination of tooth luxation. Bone composite and Bio-gide membrane were implanted, and the luxation teeth were implanted into the original site. MAIN OUTCOME MEASURES: Implantation site, composite conjugation, loose of bone formation and implanted teeth were generally observed. New bone formation at the bone defect site was observed using radiograph and histological method. RESULTS: At 12 weeks following surgery, a bone defect, which was smaller than the original bone, was found at the mandibular defect site in the blank control group. New bones were visible in the mandibular defect site in the bone composite + Bio-gide membrane group. Radiograph demonstrated that the density of defect bone site was similar to normal bone tissue. Histological method revealed that bone implant formed board-shaped bone. No significant loose was detected in implanted teeth of 17 rabbits in the bone composite + Bio-gide membrane + implantation tooth group. Radiograph demonstrated that no transparent area was found in the root tip of 13 rabbits. Histological method showed replacement resorption in 13 rabbits. CONCLUSION: Bone composite combined with Bio-gide membrane for repairing large mandibular defect obtained good efficiency. The outcome of autologous tooth implantation is acceptable in the near future.

Background and purpose: Protein kinase P1k3 could increase the transcriptional activity of p53. However, the effect of P1k3 on the transcriptional activity of p73 is still unknown. Our study was to investigate the effect of P1k3 on the transcriptional activity of p73. Methods: Luciferase reporter assay, RT-PCR and colony formation assay were adopted to study the effect of P1k3 and kinase-deficient P1k3 (K52R) on the transcriptional activity of p73 in p53-deficient human lung carcinoma H1299 cells. Results: Luciferase reporter assay showed that p73 increased the luciferase activities induced by p21~(WAF1) and Bax promoters (P<0.05). After co-transfection with p73 and P1k3, the luciferase activities induced by p21~(WAF1) and Bax promotors were significantly decreased in a dose-dependent manner as compared with the group that transfected p73 only (P<0.05). However, kinase-deficient Plk3 (K52R) had no significant effect on the luciferase activities induced by p21~(WAF1) and Bax promoters (P>0.05). RT-PCR showed that p73 increased the mRNA expressions of p21~(WAF1) and BAX (P<0.05). P1k3 decreased the expressions of p21~(WAF1) and Bax induced by p73 (P<0.05). Kinase-deficient P1k3 (K52R) had no significant effect on the expressions of p21~(WAF1) and Bax induced by p73 (P>0.05). Colony formation assay revealed that p73 decreased the colony formation of H1299 cells (P<0.05). P1k3 decreased the inhibitory effect of p73 on the colony formation of H1299 cells (P<0.05). Kinase-deficient P1k3 (K52R) had no significant effect on the inhibitory effect of p73 on the colony formation of H1299 cells (P>0.05).Conclusion: P1k3 can inhibit the transcriptional activity of p73, where as kinase-deficient P1k3 has no effect on the transcriptional activity of p73.
