Monitoring results for the period 2009-2014 by ten standard GPS stations allowed to determine the crustal movements of seismically active region in south-eastern Kazakhstan. Maps of movement velocity were made in geocentric coordinate system and in reference system of the Eurasian continent. GPS points displacements reflect the features of modern deformation processes that are notable in the high seismic activity region. The structure of the velocity field divergence qualitatively confirms major deformation in the sublatitudinal direction which is parallel to the main ridge of the northern Tianshan Mountain. The epicenters of earthquakes are in agreement with the border areas of compression -tension, as well as the allocated areas of multidirectional rotary motion. The conclusion is that GPS monitoring of the movements of the Earth＇s crust can be used to evaluate the territory＇s stress-strain state for the purpose of seismic zoning and seismic risk assessment.

Ultra fine silicon quantum wires with the Si/SiO2 heterointerface have been fabricated successfully by using reactive ion etching, anisotropic wet chemical etching and subsequent thermal oxidation. The cross-sectional image of scanning electron microscope shows the silicon quantum wires of high quality with the linewidth down to 20nm. The present method has many remarkable advantages, which is important to the study of low-dimension quantum physics and devices.

BACKGROUND： T4 hepatocellular carcinoma （HCC） with invasion to adjacent structure（s） may require resection of not only the tumor but also the invaded structure（s）. This study aims to assess whether such combined resection for T4 HCC is justifiable. METHODS： Adult patients with T4 HCC were divided into three groups. Group 1： tumors and invaded adjacent structures were resected together if histopathologically confirmed tumor invasion; group 2： same as group 1 but histopathologically confirmed tumor adhesion; group 3： tumor resection only. Group comparisons were made. RESULTS： Totally 144 patients were included in the study. There were 71, 14 and 59 patients in groups 1, 2 and 3, respec- tively. The groups were comparable in demographics, compli- cation and survival. Ten hospital deaths occurred （5, 0 and 5 in groups 1, 2 and 3, respectively; P=0.533）. The 5-year overall survival （hospital mortality excluded） was 17.8% in group 1, 14.3% in group 2, and 28.9% in group 3 （P=0.191）. The 5-year disease-free survival was 10.4% in group 1 and 14.5% in group 3 （no data for group 2 yet）（P=0.565）. On multivariate analysis, macrovascular invasion and poor differentiation were risk factors for survival whereas combined resection did not impact patients＇ survival. CONCLUSIONS： Combined resection achieved survival outcomes similar to tumor resection only. Patients with tumor invasion and those with tumor adhesion had comparable survival after combined resection. At centers with the required expertise, combined resection should be attempted to treat T4 HCCs with clinically suspected invasion of adjacent structures.

司法行为的社会影响备受关注,但对该问题的研究缺乏充足的经验证据。从金融秩序维护的角度,利用中国裁判文书网公布的破坏金融管理秩序刑事一审判决书构建地级市层面的金融司法审判指标,探讨金融司法审判对企业ESG表现的影响。研究结果显示:企业所在地的金融司法审判效率越高、上诉率越低,企业的ESG表现越好。机制分析表明,金融司法审判主要通过降低信息不对称程度、缓解企业融资约束以及增强企业风险管理意识来提高企业的ESG表现水平。进一步分析发现,对于那些拥有较多法律背景高管的企业以及处于银行机构密集城市的企业,金融司法审判的影响更加显著;而且,金融司法审判的改善还有助于降低ESG不确定性程度,以及强化ESG对企业价值的提升效应。因此,应当持续加强金融司法审判的专业化和严格化,鼓励企业主动承担ESG责任,从而实现企业和社会的“双赢”局面。

优化人口空间布局、协同推进减污和降碳,是实现中国式现代化的重要内容。本文突破行政单元约束,以超过一定人口密度阈值的网格单元作为空间观测对象,并构建2000—2020年中国19大城市群栅格数据集,精准探讨空间密度变化对减污降碳的影响及作用机制。研究发现,网格单元空间密度对PM2.5与人均碳排放的影响均呈“倒U”型趋势,拐点值分别为3718人/km2和4128人/km2。这主要受四大作用机制影响,即城市用地变迁、生态空间演变、生产方式优化和交通设施变化。进一步分析空间密度的规模效应与结构效应表明,规模效应的主导地位造就了密度与环境的非线性关系,这为相关研究争论提供了新的解释。本文也为如何从空间布局层面推动减污降碳协同增效提供了政策启示。

Dear Editor, The current standard 12-core systematic transrectal ultrasound （TRUS）-guided biopsy in prostate cancer diagnosis has the disadvantages of overdetecting indolent tumors, while failing to identify clinically significant cancers in up to 35%.1 Advances in imaging techniques, notably the multiparametric magnetic resonance imaging （mpMRI）, allow clinically significant prostate cancers to be detected with more precise localization） Fusion of MRI and real-time TRUS enables targeted biopsy of suspicious lesions, overcoming human error, and inability of biopsy site tracking in cognitive fusion？ Multiple Western series have suggested a higher detection rate, higher specificity, and better risk stratification with fusion biopsy.

We investigated the prostate cancer detection rates upon transrectal ultrasound （TRUS）-guided biopsy in relation to digital rectal examination （DRE） and prostate-specific antigen （PSA）, and risk factors of prostate cancer detection in the Chinese population. Data from all consecutive Chinese men who underwent first TRUS-guided prostate biopsy from year 2000 to 2013 was retrieved from our database. The prostate cancer detection rates with reference to DRE finding and PSA level of 〈 4, 4-10, 10.1-20, 20.1-50 and 〉 50 ng ml^-1 were investigated. Multivariate logistic regression analyses were performed to investigate for potential risk factors of prostate cancer detection. A total of 2606 Chinese men were included. In patients with normal DRE, the cancer detection rates were 8.6%, 13.4%, 21.8%, 41.7% and 85.2% in patients with PSA 〈 4, 4-10, 10.1-20, 20.1-50 and 〉 50 ng ml^-1 respectively. In patients with abnormal DRE, the cancer detection rates were 12.4%, 30.2%, 52.7%, 80.6% and 96.4% in patients with PSA 〈 4, 4-10, 10.1-20, 20.1-50 and 〉 50 ng m1-1 respectively. Older age, smaller prostate volume, larger number of biopsy cores, presence of abnormal DRE finding and higher PSA level were associated with increased risk of prostate cancer detection upon multivariate logistic regression analyses （P 〈 0.001）. Chinese men appeared to have lower prostate cancer detection rates when compared to the Western population. Taking the different risk factors into account, an individualized approach to the decision of TRUS-guided biopsy can be adopted.
