Methods A total of 354 patients with subarachnoid hemorrhage who were hospitalized in our hospital from January 2017 to July 2021 were selected, and compared with 217 healthy individuals during the same period. The 4 parameters in platelet venous blood before and after surgery were analyzed: platelet count (Plt), mean platelet volume (MPV), platelet volume (PCT), and platelet distribution density (PDW). Results Before operation: Platelet count (PLT) decreased compared with the normal control group (p&lt;0.01), MPV and PDW were increased compared with the normal control group (p&lt;0.01); PLT increased after operation (p&lt;0.01), but higher than that of the normal control group. Conclusions Early surgical treatment of aneurysmal subarachnoid hemorrhage can seal the ruptured blood vessel, reduce the exposure of endothelial cells, inhibit platelet activation, and reduce the formation of microthrombi.</p> Jinglian Zhou Copyright (c) 2022 Thu, 22 Dec 2022 00:00:00 -0500 Design of Automatic Distribution System for Storage Logistics Trolley <p>In order to improve the automation of warehousing and logistics distribution, the design and development of warehousing and logistics trolley automatic distribution system is realized with the cost-effective PLC control module as the core.

With the rapid increase of the number of shore power facilities, the monitoring and management details of shore power facilities cannot meet the requirements, and the focus of the promotion of shore power is shifted to management. In order to better manage the shore power facilities and better serve the use of ship shore power, a ship shore power information management system is designed and implemented. This system is based on the Spring Boot and Vue framework, and is implemented through technologies such as front-end and back-end separation, mixed APP, and multi-level storage architecture. The application of the system effectively supports the high-quality development of ship shore power, and the data acquisition through the supervision module can scientifically guide the construction of ship shore power facilities.</p> Yujuan Zou, Peiyi Tang, Taizhi Lv Copyright (c) 2022 Thu, 22 Dec 2022 00:00:00 -0500 Research on the Promotion Path of Public Space Vitality of Traditional Villages based on GIS and Space Syntax <p>From the perspective of the three current situations of "social structure investigation - public space identification - spatial vitality status", and according to the logical idea of "element identification-analysis and evaluation-information spatialization-relationship establishment", syntactic analysis, GIS spatial distribution analysis, GIS status spatial vitality analysis are carried out, and the causes of the use of public space in the current villages are analyzed and continuously corrected, and the influence scheme of the vitality of traditional village public space is obtained in the analysis and feedback between the three plates. And propose an optimization path.</p> Jing Luo, Wei Chen, Huilin Wang, Shujing Li Copyright (c) 2022 Thu, 22 Dec 2022 00:00:00 -0500 Research on the Construction Mode of Excellent Teaching Team in Colleges and Universities <p>Starting from the role of teaching teams in colleges and universities, this paper analyzes the main problems in the construction of teaching teams in terms of team structure, cooperation mechanism, development planning, performance appraisal mechanism, and puts forward multiple construction models and operation management methods for constructing excellent teaching teams in terms of constructing three-level and six category teaching teams, constructing virtual teaching teams, and constructing double qualified teaching teams.</p> Xiaomei Hu, Hui Li, Zejiong Zhou Copyright (c) 2022 Thu, 22 Dec 2022 00:00:00 -0500 An Empirical Analysis on the Influencing Factors of Economic Growth in Shanxi Province <p>Since the reform and opening up, the national economy has entered a new stage of development. As a major energy province, Shanxi's stable economic development has also attracted attention. This paper analyzes the four aspects that affect Shanxi's economic growth, namely, labor force, material capital investment, technological progress and energy consumption. Through the establishment of double logarithm model, parameter estimation, model test and analysis are carried out to explore the influencing factors of its economic development. Based on this, the potential of Shanxi's economic development is found, and reasonable suggestions are put forward for promoting Shanxi's economic development.</p> Ruiyao He, Zejiong Zhou Copyright (c) 2022 Thu, 22 Dec 2022 00:00:00 -0500 Study on Pyrolysis Hydrocarbon Generation Kinetics and Shale Gas Formation Process of Marine Continental Transitional Rocks in Shanxi Formation, Ordos Basin <p>The marine continental transitional facies shale of Shan<sub>2</sub><sup>3</sup> sub member of Shanxi Formation in Ordos Basin was selected, and the hydrocarbon generation kinetics of Shan 23 sub member marine continental transitional facies shale was studied through open system thermal simulation experiment. The experimental results show that the pre exponential factor of Shan 23 shale is 12.92*10<sup>15</sup>/s, and the activation energy is mainly concentrated in 52~82kcal/mole. On this basis, combined with petromod basin simulation software, the burial history, thermal evolution history and hydrocarbon generation history of Shanxi Formation shale are established, and the formation process of shale gas is clarified. Finally, using the genetic method, combined with the original TOC restored by Petromod basin simulation software and the hydrocarbon generation obtained from the open system thermal simulation experiment, the resources of the study area are calculated when the hydrocarbon expulsion efficiency is 50%. The calculation results show that the shale gas resource in the study area is 12.41*10<sup>12</sup>m<sup>3</sup>, which shows a good exploration potential of sea land transitional facies shale in the study area.</p> Zhiwei Ma, Zhiming Xu, Xiaogang Li, Xiang Li, Jungang Lu, Yong Li, Qingbo He, Liping Zhao Copyright (c) 2022 Thu, 22 Dec 2022 00:00:00 -0500 Research on Land Renovation Planning Strategy based on Digital Surveying and Mapping Technology <p>With the rapid growth of new surveying and mapping technology and surveying and mapping instruments, engineering surveying has also been developed rapidly. Land survey is a foundation for the country to effectively manage and plan land. When land is used, relevant information can be found in the database established in previous land surveys, so its accurate measurement method is particularly important. On the one hand, there are more and more land surveying work, and the surveying and mapping data of land surveying units are more accurate. On the other hand, with the increasing difficulty of land surveying, surveying units have put forward higher requirements for surveying and mapping technology. Under the background of the continuous growth of China's economy and society, the level of network information technology has improved rapidly, and digital information technology is widely used in land survey, which can improve the efficiency of land survey. This paper analyzes the application of digital mapping technology in land consolidation planning, hoping to provide some reference and suggestions for the smooth growth of land consolidation planning and the improvement of the accuracy of survey results.</p> Ruiyi Murong Copyright (c) 2022 Thu, 22 Dec 2022 00:00:00 -0500
