AIM to determine whether diabetes mellitus(DM) affects prognosis/recurrence after liver transplantation(Lt) for hepatitis B virus(HBV)-related hepatocellular carcinoma(HCC). METHODS A retrospective study was conducted between January 2000 and August 2013 on 1631 patients with HBV-related HCC who underwent Lt with antiviral prophylaxis. Patient data were obtained from the China Liver transplant Registry(https://***/). to compare the outcomes and tumor recurrence in the HBV-related HCC patients with or without DM, statistical analyses were conducted using χ2 tests, Mann-Whitney tests, the Kaplan-Meier method, log-rank tests and multivariate step-wise Cox regression analysis. RESULTS Univariate analysis of 1631 patients who underwent Lt found overall 1-, 3- and 5-year survival rates of 79%, 73% and 71% respectively in the DM patients, and 84%, 78% and 76% in the non-DM patients respectively. Overall survival rate differences after Lt between the two groups were significant(P = 0.041), but recurrence-free survival rates were not(P = 0.096). By stratified analysis, the overall survival rates in DM patients for age > 50 years(P = 0.002), the presence of vascular invasion(P = 0.096), tumors ≤ 3 cm(P = 0.047), two to three tumor nodules(P = 0.007), Child-Pugh grade B(P = 0.018), and preLt alanine aminotransferase levels between 40 and 80 IU/L(P = 0.017) were significantly lower than in non-DM patients. Additionally, serum α-fetoprotein level > 2000 ng/m L(P = 0.052) was associated with a significant survival difference trend between DM and non-DM patients. Multivariate analysis showed that the presence of DM(P < 0.001, HR = 1.591; 95%CI: 1.239-2.041) was an independent predictor associated with poor survival after Lt. CONCLUSION HBV-related HCC patients with DM have decreased long-term overall survival and poor Lt outcomes. Prevention strategies for HCC patients with DM are recommended.

In this review article, the progress and recent developments in the measuring and controlling of single atom trajectories are reviewed. With the development of laser cooling and trapping technology, it is possible to achieve the measurement and control of single atom trajectory experimentally. The experiment of tracking a single atom trajectory with high resolution and the endeavor of eliminating the degeneracy of the trajectories are then introduced.

在切削加工粉末高温合金过程中,严重的塑性变形导致已加工表面出现显微组织结构和力学性能的变化。在已加工表面出现的白层体现出加工表面显微结构和力学性能的变化,对高温合金加工表面质量的影响至关重要。为了揭示粉末高温合金已加工表面显微组织结构和力学性能的变化,开展了切削速度对粉末高温合金FGH95已加工表面白层形成影响的研究。研究发现随着切削速度的提高,FGH95高温合金已加工表面出现的白层厚度增大。对加工表面进行显微观察发现在表面覆盖着一层致密的、无明显组织特征的白层结构。通过对加工前后材料的XRD测试分析得出FGH95粉末高温合金基体材料以Ni基固溶体的形式存在,而加工之后表面的显微组织结构则明显与基体材料不同。这说明在切削过程中粉末高温合金已加工表面发生了Ni基固溶体组织结构的变化。对FGH95高温合金已加工表面进行晶粒度测量发现,切削速度越高晶粒细化现象越明显。对高温合金切削表面白层进行力学性能测试表明,白层的显微硬度随着切削速度的提高而增大;存在于高温合金已加工表面白层中的残余应力为拉应力,且随着切削速度的提高拉应力增大。粉末高温合金已加工表面显微结构和力学性能变化研究可以揭示高温合金表面完整性的形成机理,为已加工表面质量的预测和控制提供理论依据。

随着我国社会主义民主政治建设的发展,媒体对公安工作监督的力度、对警务活动的影响越来越大,公安工作对媒体的依赖性增强,因而公安机关必须构建与媒体的良性互动关系。警察与媒体的关系需要运用国家与社会关系理论、沟通协调理论、权利与义务关系理论以及博弈理论进行分析。在现实生活中,警察与媒体关系是多维度的:在政治上,双方是被监督与监督的关系;在法律上,双方是互有权利与义务的平等关系;在工作上,双方是既合作又冲突的关系。
