The temporal and spatial characteristics of ecological risk are important basis for scientific management and control of ecological risk. In the past, the traditional spatio-temporal analysis method of ecological risk change did not fully consider the spatio-temporal correlation. Taking Gansu Province as an example, the ecological risk index (ERI) was calculated based on ecosystem services value (ESV) from 1980 to 2018, and the evolution characteristics of ecological risk were analyzed using Bayesian Spatio-temporal Model (BSTM). The results showed that: (1) ESV decreased first and then increased with 2000 as the boundary, and grassland and cultivated land contributed the most to ESV. (2) The overall trend of ERI was consistent with that of ESV, and the risk increase rate gradually slowed down after 2010. (3) The spatial pattern of ERI was characterized by "high in the south and low in the north, with a transition in the middle". The hot spots were mainly distributed in some regions of Longnan, Longdong and Gannan, while the cold spots were mainly concentrated in Hexi. (4) There were significant regional differences in the local variation trend of ERI. Overall, the trend of ERI increased around Jiayuguan and Lanzhou as the center, and the variation of ERI in Southern and eastern Gansu was stronger than that in Hexi. The hot spots of local variations were mainly distributed in southern and eastern Gansu. [ABSTRACT FROM AUTHOR]

Based on the time series data of Kaifeng City, Henan Province from 2017 to 2021, this paper establishes an index measurement method for human capital-industrial structure upgrading, designs a systematic coupling model of human capital and industrial structure, tests the coupling and coordination degree of the two, and studies the matching relationship between human capital and industrial structure in Kaifeng City in combination with the economic development level in the target time. Furthermore, it provides policy reference and suggestions for non-first-tier and second-tier cities with similar level to Kaifeng city and slightly inferior in economic development. In terms of human capital policy, local cities should take measures such as increasing investment in education, implementing special training programs for multi-level talents and opening channels for social talents to meet the needs of higher-level development of industrial structure and realize rationalization and upgrading of industrial structure. In terms of industrial structure policies, local cities should consider the actual basis of human capital. The industrial structure adjustment plan adopted should be coordinated with the development level of human capital. Local cities that are not first-tier or second-tier cities should learn to "group" adjustment and reasonably plan the industrial development path. [ABSTRACT FROM AUTHOR]

Crossing the middle and lower reaches of the Yellow River, Henan Province is the main body of the Central Plains Economic Zone. It plays an important role in the national economic construction and the high-quality development of Henan Province along the Yellow River economic belt is related to the ecological protection and high-quality development of the entire Yellow River Basin. In order to provide a reference for the high-quality economic development of Henan Province and its economic belt along the Yellow River and the high-quality development of the entire Yellow River Basin, the super-efficiency Super-SBM model, Malmquist index and Moran index were used to evaluate the eco-economic efficiency of Henan Province and the eight cities along the Yellow River and analyze the temporal and spatial distribution characteristics and evolutionary laws. The results show that the eco-economic efficiency of Henan Province fluctuates from 0.831 to 0.921 from 2007 to 201 7 and it has not yet reached the full efficiency stage, that is, the allocation of ecological economic resources is unreasonable and the construction of ecological economy needs to be strengthened ; the eco-economic efficiency of the eight cities along the Yellow River are quite different, with the exception of Luoyang City showing an upward trend; the total factor productivity of the ecological economy of Henan Province is on the rise and the total factor productivity of the ecological economy in the eight cities along the Yellow River in Jiyuan and Zhengzhou has changed relatively smoothly, the Malmquist index fluctuates slightly around 1.0, while the other six cities have relatively large fluctuations in the total factor productivity of the ecological economy, the Malmquist index has a large peak in 2009-2010 and 2015-201 6 respectively ; from the perspective of differences in spatial distribution, the differences in eco-economic efficiency of cities in Henan Province are gradually narrowed, the global spatial correlation is weak in 2007 and is further weakened to random distribution in 2017 and a small number of cities show agglomeration characteristics.

The purpose of tumor staging is to guide treatment, and the treatment for a certain stage should be adjusted based on the changes in disease condition, in order to facilitate better control of tumor. Therefore, the treatment of liver cancer requires follow-up and re-staging to develop better treatment regimens for patients, especially the opportunity for cure. Surgical resection is not suitable for large hepatocellular carcinoma confined to the liver, and after embolization chemotherapy combined with radiotherapy for tumor regression and downstaging, some patients may undergo surgical resection, and the incurable tumor can thus be cured. For liver cancer patients with portal vein tumor thrombus, surgical resection can be performed after tumor thrombus is reduced by neoadjuvant radiotherapy, and the patients undergoing neoadjuvant radiotherapy have a significant increase in survival time than those not undergoing neoadjuvant radiotherapy. Large hepatocellular carcinoma can be downstaged to small hepatocellular carcinoma after multimodality therapy, and then stereotactic radiotherapy or radiofrequency ablation can help to achieve radical treatment. There is an increasing number of clinical reports of radiotherapy for liver cancer downstaging, with a gradual increase in evidence-based level, and thus it holds promise for clinical application.

It has an important task on the practical personnel training in higher education, also, as an important place for the cultivation of practical talents, it got the attention from all kinds of colleges and universities during the establishment of experimental teaching center. In order to further improve the quality of the cultivation of talents, this paper takes the experimental teaching center of Harbin Engineering University, the training method and mode of virtual experiment teaching center as the breakthrough point,and systematically introduces the training mode and characteristics of innovative talents, expounds the realization process of "university computer basis education base, scientific and technological innovation base and engineering practice ability training base". The practice shows that the construction of the experimental teaching center of the trinity is heljDful to improve the practical ability of the college students and the consciousness of thinking, the combination of social needs, and improve the quality of personnel training.
