Climate change in the 21st century over China is simulated using the Abdus Salam International Centre for Theoretical Physics (ICTP) Regional Climate Model version 3 (RegCM3). The model is one-way nested within the global model CCSR/NIES/FRCGC MIROC3.2_hires (Center for Climate System Research/National Institute for Environmental Studies/Frontier Research Center for Global Change/Model for Interdisciplinary Research on Climate). A 150-year (1951-2100) transient simulation is conducted at 25 km grid spacing, under the Intergovernmental Panel on Climate Change Special Report on Emissions Scenarios (IPCC SRES) A1B scenario. Simulations of present climate conditions in China by RegCM3 are compared against observations to assess model performance. Results show that RegCM3 reproduces the observed spatial structure of surface air temperature and precipitation well. Changes in mean temperature and precipitation in December-January-February (DJF) and June-July-August (JJA) during the middle and end of the 21st century are analyzed. Significant future warming is simulated by RegCM3. This warming becomes greater with time, and increased warming is simulated at high latitude and high altitude (Tibetan Plateau) areas. In the middle of the 21st century in DJF, a general increase of precipitation is found in most areas, except over the Tibetan Plateau. Precipitation changes in JJA show an increase over northwest China and a decrease over the Tibetan Plateau. There is a mixture of positive and negative changes in eastern China. The change pattern at the end of the century is generally consistent with that in mid century, except in some small areas, and the magnitude of change is usually larger. In addition, the simulation is compared with a previous simulation of the RegCM3 driven by a different global model, to address uncertainties of the projected climate change in China.

Extreme weather events such as persistent high temperatures, heavy rains or sudden cold waves in Shanxi Province in China have brought great losses and disasters to people’s production and life. It is of great practical significance to study the temporal and spatial distribution characteristics of extreme weather events and the circulation background field. We selected daily high temperature data (≥35°C), daily minimum temperature data and daily precipitation data (≥50 mm) from 109 meteorological stations in Shanxi Province, China from 1981 to 2010, then set the period in which the temperature is ≥35°C for more than 3 days as a high temperature extreme weather event, define the station in which 24 hour cumulative precipitation is ≥50 mm precipitation on a certain day (20 - 20 hours, Beijing time) as a rainstorm weather, and determine the cold air activity with daily minimum temperature dropped by more than 8°C for 24 hours, or decreased by 10°C for 48 h, and a daily minimum temperature of ≤4°C as a cold weather process. We statistically analyze the temporal and spatial characteristics and trends of high temperature, heavy rain and cold weather and the circulation background field. We count the number of extreme weather events such as persistent high temperatures, heavy rains and cold weather frosts in Shanxi, and analyze the temporal and spatial distribution characteristics, trends and general circulation background of extreme weather events. We analyze and find out the common features of the large-scale circulation background field in various extreme weather events. Through the study of the temporal and spatial distribution characteristics of extreme weather events in Shanxi, including persistent high temperature, heavy rain or sudden cold wave frost weather, we summarize the large-scale circulation characteristics of such extreme weather events. It will provide some reference for future related weather forecasting.

Bacterial infection due to coronary angiography is an uncommon but important complication of percutaneous coronary intervention (PCI) which is responsible for significant morbidity and extended hospital stay. The reasons for this symptom are still unclear. We report a case of local groin abscess two weeks after the latest procedure. The reasons responsible for the groin abscess in this case might be diabetes mellitus without being properly controlled, left ventricular (LV) systolic dysfunction, multiple operations in the same site, the usage of vascular closure device (VCD), and long time pressure after the procedure. We should pay enough attention to these risk factors in the future clinical practice to avoid this serious complication.

Demographic, clinical and pathological variables and survival data were ***： The pancreas was the most common site of involvement（63/154, 40.9%）. Tumor size varied from 0.3 to 16.0 cm（median, 1.2 cm）. The patients were followed up for a median period of 22 months（range, 1-157 months）. The estimated 3- and 5-year overall survival（OS） rates for all patients were 84.0% and 81.9%, respectively. Multivariate analysis showed that larger tumor size, lymphatic metastases and distant metastases were significant predictors for poor survival ***： Our data provide further information on the clinicopathological features of GEP-NENs in China. Additionally, we identified tumor size, lymphatic metastases and distant metastases as independent prognostic factors for long-term survival.

“坚持理论创新”是中国共产党百年奋斗的宝贵历史经验之一。从辩证唯物主义实践论来看,理论创新与实践创新之间是一个长期的互动过程,是具体的历史的动态的统一。从历史唯物主义的现实观来看,理论创新要立足于社会现实,一切从实际出发,是求真与求善的统一。从历史上来看,中国共产党的理论创新就是中华民族追求现代化与实现马克思主义中国化的统一。中国特色社会主义的百年求索之路再次确证了要始终坚持以马克思主义为指导,立足中国各个历史阶段的社会现实,实事求是地推进理论创新并取得实践成效。在习近平新时代中国特色社会主义思想的指导和引领下,中国共产党必将在第二个百年继续发挥核心作用,必将极大地推进中国社会主义现代化新实践。

在基本判断形式“S是P”中,作为系词的“是”是判断的核心,但也是最难以理解的,不同的逻辑学家对“是”进行了不同的解释,众说纷纭,莫衷一“是”。一方面,本文从辩证法-认识论-逻辑学相统一的视角探讨判断系词“是”的内涵,站在马克思主义认识论与唯物辩证法的高度俯瞰系词“是”,超出了逻辑学窠臼,拓宽了“是”的真理含义。另一方面,本文从马克思主义反映论与实践论立场,批判了黑格尔逻辑主义、逻辑经验主义、逻辑先验主义对“是”的片面的狭隘理解,论证了判断的本质及其系词“是”的辩证法含义。从矛盾律的“或是或否”发展到“又是又否”的矛盾论具有客观必然性,矛盾论才是支配整个现实现世与社会生活的根本规律。
