A magnitude of 8.0 earthquake struck on Wenchuan on May 12, 2008. Until July 1, 1393 injured persons had been admitted to Deyang People's Hospital. Of all injured persons, 32 were diagnosed with abdominal injury, including 18 men and 14 women. All the abdominal injuries were closed injury, and multiple abdominal viscera were involved in the abdominal injuries after the earthquake. Careful examination is crucial in preventing missed diagnosis. The incidences of the liver and spleen injuries were significantly higher than that of the intestine, and the reason may be that the liver and spleen are the parenchymal viscera. Diagnostic abdominocentesis can timely diagnose the parenchymal viscera with severe blood loss. Diagnostic peritoneal lavage combined with selective CT scan can timely diagnose the abdominal injuries with comparatively low cost.

[Objective]To explore the feasibility and safety of percutaneous kyphoplasty(PKP) and percutaneous vertebroplasty(PVP) treating osteolytic lesions of high thoracic vertebra with metastasis by one side extrapedicular approach,and to assess the clinical result of minimally invasive technique. [Methods]In March 2008,one patient(male,59 years old) with T1~3 vertebral metastases of lung cancer diagnozed 8 months ago was selected.The symptoms included extremely severe pain in upper thoracic spine and left should.The analgesic effect was limited for more than 6 months.There was no operative option.Domestic PKP and PVP tool systems were used in local anaesthesia.Under fluoroscopic guidance,T2 and T3 vertebral augmentation were separately completed by single side extrapedicular approach PKP and PVP.Clinical results were followed up and observed.[Results]The procedure was performed smoothly.T3 and T2 vertebrae were differently treated by PKP and PVP.T1 received no treatment because of patient`s intolerance.The operative time of T3 vertebral PKP was 57 minutes.The volume of injected bone cement was 1.9ml.The operative time of T2 vertebral PVP was 49 minutes.The volume of injected bone cement was 1.5ml.Extravertebral leakage of the polymethylmethacrylate(PMMA) into the paravertebral itssue was found without clinical symptom,because osteolysis occurred in the left pedicle of T2 vertebra.There was no other complication.The patient was discharged 5 days after operation.The preoperative,2 days and 3 months postoperative follow-up VAS scores were 10,3 and 6.The patient's markedly pain could be controlled by analgesia.[Conclusion]One side approach percutaneous kyphoplasty is a safe and effective technique for treatment of high thoracic vertebral metastasis with markedly relief of pain.

Objective To investigate the Th1/Th2 polarization of T lymphocytes in human peripheral blood stimulated by CpG-ODN2216,and the secretion of cytokines in supernatant of cultured PBMCs after stimulation of CpG-ODN2216.Methods Human PBMCs were isolated from blood of donors.The PBMCs were incubated with CpG-ODN2216 for 24 hours.Th1/Th2 subsets in the cultured PBMCs were examined by flow cytometry,and IFN-?,IL-2,IL-4 and IL-10 in the supernatant were assayed by ELISA.Results The percentage of Th1 and Tc1 increased significantly after stimulation of CpG-ODN2216 compared with control group (P0.05).Conclusion The Th1 cells and Tc1 cells in T lymphocytes of peripheral blood could be polarizated by CpG-ODN 2216.IFN-? secretion in PBMCs could be induced by CpG-ODN2216.

Objective To develop a visible detection system prepared by protein microarrays which was based on GoldMag particles-labeled technique and compare the results of detection using the protein which was labeled with GoldMag particles and colloidal gold.Methods Human IgG was printed on the glass slides modified with epoxy groups,and goat anti-human IgG conjugated with GoldMag particles and colloidal gold respectlively was then added on the slide.The glass slides were incubated,and then the black images of microarray spots were produced by immuno-gold-silver staining method and observed by naked eyes and recorded with common flatbed scanner.Results The high signal-to-noise ratio could be obtained when the optimized procedures of GoldMag particles-labeling probe were introduced to the protein chip.The conditions of optimum assay were as follows:the spotting concentration of human IgG was 0.2 mg/ml,the glass slides were incubated at 37 ℃ for 2 hour to immobilize human IgG,and the silver enhancement time was 10 min-15 min.Parallelly,the optimized conditions for colloidal gold were as follows:the spotting concentration of human IgG was 0.1 mg/ml,the slides were incubated at 37 ℃ for 1 hour to immobilize human IgG,and the silver enhancement time was 15 min-20 min.Conclusions GoldMag particles-labeled protein technique is comparable to colloidal gold in applying to protein microarrays.The method is considerably simple and practical,and the protein labeled by GoldMag particles could be quantitative.

Objective To investigate the effect of expression of pituitary tumor transforming gene(PTTG) on the expression of inhibitory of vascular endothelial growth factor(VEGF).Methods The constructed(recomibinant) vector,pcDNA3.1-PTTGas that contained full-length antisense PTTG,was transfected into the cholangiocarcinoma cell line QBC939 in different quantity.After 48h incubation,the variation of expressions of PTTG and VEGF mRNAs and proteins were observed by RT-PCP and Western-blot method.Results(After) successful transfecting the recomibinant vector into QBC939,the mRNAs and proteins of PTTG and VEGF were all inhibited.Linear correlation analysis showed positive correlation between descendent extents of PTTG and VEGF(P

Objective To summarize the 18F-FDG PET/CT findings of LCH in children,and explore its value in the diagnosis of LCH.Methods PET/CT imaging and clinical data of 13 patients (6 males,7 females;average age (3.0±2.3) years) with LCH confirmed by histology before treatment from August 2011 to December 2015 in Xin Hua Hospital were retrospectively analyzed.Results All 13 patients have different degrees of bone destruction with increased metabolism,the common lesion sites were craniofacial bone,spine,limb long bones,ribs/chest/shoulder blade and pelvic bone.Lymph node lesions which manifested lymph node enlargement with increased metabolism were found in 10 cases,and the SUVmax was 4.0±1.3.Diffuse FDG uptake in spleen was found in 10 cases.There were 4 cases with liver lesions,3 with lung lesions,1 with high metabolic nodules in muscle,1 with orbital lesions and 1 with intraspinal high metabolic nodules.Conclusion 18F-FDG PET/CT could display the distribution and activity of LCH,and plays an important role in the diagnosis and systemic evaluation of LCH.
