AIM:To investigate the predictive factors of selfexpandable metallic stent patency after stent placement in patients with inoperable malignant gastroduodenal obstruction. METHODS:A total of 116 patients underwent stent placements for inoperable malignant gastroduodenal obstruction at a tertiary academic center. Clinical success was defined as acceptable decompression of the obstructive lesion within the malignant gastroduodenal neoplasm. We evaluated patient comorbidities and clinical statuses using the World Health Organization's scoring system and categorized patient responses to chemotherapy using the Response Evaluation Criteria in Solid Tumors criteria. We analyzed the relationships between possible predictive factors and stent patency. RESULTS:Self-expandable metallic stent placement was technically successful in all patients(100%),and the clinical success rate was 84.2%. In a multivariate Cox proportional hazards model,carcinoembryonic antigen(CEA) levels were correlated with a reduction in stent patency [P = 0.006; adjusted hazard ratio(a HR)= 2.92,95%CI:1.36-6.25]. Palliative chemotherapy was statistically associated with an increase in stent patency(P = 0.009; a HR = 0.27,95%CI:0.10-0.72).CONCLUSION:CEA levels can easily be measured at the time of stent placement and may help clinicians to predict stent patency and determine the appropriate stent procedure.

研究经学院伦理委员会批准并有病人知情同意书。虽然氙（Xe）通气CT已经作为显示通气区域的一种潜在方法，但由于不同扫描时肺的不同容积造成的肺X线不同密度限制了Xe增强定量的应用。本研究的目的是评估利用双能技术进行Xe通气CT的可行性。12例受试者在吸入Xe后进行了双能CT扫描。使用了双能技术后，Xe的成分可被提出而不受肺容积的影响．可显示肺区域性动态与静态的通气功能，与薄层CT影像匹配精确。

＜正＞ A numerical scheme for solving three dimensional viscoelastic flow was developed. Three dimensional finite volume method （FVM） based on non-staggered grid and semi-implicit method for pressure linked equations （SIMPLE） were adopted to solve the continuity and momentum equations. As we used non-staggered grid, momentum interpolation method （MIM） was employed to avoid the checker-board type pressure fields. Viscoelastic properties of the fluid were described by the Phan-Thien and Tanner （PTT） model, which was treated by the compressive interface capturing scheme for arbitrary meshes （CICSAM）. Elastic viscous split stress scheme （EVSS） was used to decouple the velocity and the stress fields. Algebraic equations obtained by the above schemes were handled by an iterative solver and multi-grid method was applied to accelerate the convergence. In order to verify the scheme developed in this study, Newtonian flow in a rectangular duct was studied and the resulting velocity fields were compared with the analytical flow fields. Then viscoelastic flow in a 4:1 contraction geometry, one of the most frequently used benchmarking problems, was predicted by applying fully three dimensional finite volume method.

Background: Proton-impact metallic nanoparticles, inducing low-energy electrons emission and characteristic X-rays termed as Coulomb nanoradiator effect (CNR), are known to produce therapeutic enhancement in proton treatment on experimental tumors. The purpose of this pilot study was to investigate the effect of CNR-based dose enhancement on tumor growth inhibition in an iron-oxide nanoparticle (FeONP)-loaded orthotopic rat glioma model. Methods: Proton-induced CNR was exploited to treat glioma-bearing SD rat loaded with FeONP by either fully-absorbed single pristine Bragg peak (APBP) or spread-out Bragg peak (SOBP) 45-MeV proton beam. A selected number of rats were examined by MRI before and after treatment to obtain the size and position information for adjusting irradiation field. Tumor regression assay was performed by histological analysis of residual tumor in the sacrificed rats 7 days after treatment. The results of CNR-treated groups were compared with the proton alone control. Results: Intravenous injection of FeONP (300 mg/kg) elevated the tumor concentration of iron up to 37 μg of Fe/g tissue, with a tumor-to-normal ratio of 5, 24 hours after injection. The group receiving FeONP and proton beam showed 65% - 79% smaller tumor volume dose-dependently compared with the proton alone group. The rats receiving FeONP and controlled irradiation field by MR imaging demonstrated more than 95% - 99% tumor regression compared with MRI-determined initial tumor size. Conclusions: Proton-impact FeONP produced therapeutic enhancement compared with proton alone in an orthotopic rat glioma model at a selected temporal point after treatment. Single BP proton beam could induce CNR- based dose enhancement and produce enhanced tumor regression that was comparable to SOBP treatment despite inhomogeneous tumor dose in the APBP-treated tumor. These results may suggest emergence of novel Particle Induced Radiation Therapy (PIRT) on malignant glioma.
