目的 寻找脑动脉夹层相关卒中复发的高风险影像学特征，探讨责任动脉闭塞与其复发的关系。 方法 前瞻性连续性纳入2018年1月-2022年2月在郑州大学第一附属医院住院的首发脑动脉夹层相关卒中患者，通过MRI、MRA、CTA、HR-MRI及DSA等影像学方法评估血管闭塞、长节段夹层等影像学特征，长期随访其复发情况。通过单因素、多因素COX回归分析其复发的影响因素，构建Kaplan-Meier生存曲线评估血管闭塞与脑动脉夹层相关卒中复发的关系。 结果 共纳入107例脑动脉夹层相关卒中患者，有10例（9.3%）患者复发。单因素及多因素COX回归分析提示，责任动脉闭塞是脑动脉夹层相关卒中复发患者预后不良的独立预测因子（HR 6.150，95%CI 1.227～30.810，P=0.027），出血转化也与脑动脉夹层相关卒中复发显著相关（HR 12.605，95%CI 2.373～66.949，P=0.003）。Kaplan-Meier生存曲线提示，闭塞组与非闭塞组卒中复发率差异具有统计学意义（Log-rank P=0.001）。 结论 责任动脉闭塞是脑动脉夹层相关卒中复发的危险因素，需要大样本研究进一步验证本研究结果，为二级预防提供更精准的帮助。 Abstract: Objective To investigate the relationship between culprit cerebral artery occlusion and cerebral artery dissection (CAD)-related stroke recurrence. Methods The patients with first CAD-related ischemic stroke who were admitted in the First Affiliated Hospital of Zhengzhou University from January 2018 to February 2022 were prospectively included in this study. CTA, MRA, HR-MRI, DSA and other imaging methods were used to evaluate the imaging characteristics of culprit cerebral artery occlusion and long-segment dissection; and the long-term imaging follow-up was performed to evaluate stroke recurrence. COX regression analysis was used to evaluate the risk factors of stroke recurrence, and Kaplan-Meier survival curve was constructed to evaluate the relationship between cerebral artery occlusion and CAD-related stroke recurrence. Results A total of 107 cases were included in the analysis, with stroke recurrence in 10 patients (9.7%). Cox regression analysis showed that culprit artery occlusion (HR 6.150, 95%CI 1.227-30.810, P=0.027) and hemorrhagic transformation (HR 12.605, 95%CI 2.373-66.949, P=0.003) were independent risk factors of CAD-related stroke recurrence. The Kaplan-Meier survival curve showed that there was statistical difference in stroke recurrence between artery occlusion and non-occlusion groups (Log-rank P=0.001). Conclusions Artery occlusion is a risk factor of CAD-related stroke recurrence.

[Objective] The aims of this study are to explore the response of ecosystem service value to land use change and predicting future trends, and to provide scientific reference for land use pattern planning in the arsenic sandstone area. [Methods] Based on the remote sensing images of the four phases of sandstone area from 2000 to 2020, the change characteristics of LUCC and ESV in the past 20 years were analyzed based on GIS technology and ESV evaluation methods. The response of LUCC induced by ESV was revealed. The development trend of LUCC and ESV was predicted by using Markov model. [Results] (1) In 2000- 2020, the total area of LUCC remained unchanged, and the increase of construction land was the most obvious, with a total increase of 762.73 km² and a growth rate of 4.57%. The grassland decreased by 548.79 km² in total, with a reduction rate of 3.28%. (2) The overall level of ESV showed a downward trend, from 19 949.65 million yuan to 18 997.19 million yuan, a decrease of 4.78%, of which grassland ESV changed the most, decreasing by 746.29 million yuan, accounting for 78.35% of the overall decline rate. (3) ESV was positively correlated with the changes in grassland, woodland, cultivated land, water area and construction land, and negatively correlated with unused land. (4) It is predicted that the area of cultivated land, forest land, grassland and water area will decrease to 96.69%, 98.94%, 94.27% and 99.12% of those in 2020 in the next 10 years. Construction land and unused land will increase to 150.03% and 121.61%, and the overall ESV level in sandstone area will continue to decrease to 92.81%. [Conclusion] The areas of cultivated land, forest land, grassland, and water are decreasing, while the area of construction land and unused land will increase. ESV will continue to decrease, and there is a linear relationship between ESV changes and land use changes. In the future, the area of construction land will increase, and ESV will continue to decrease. Reasonably adjusting the area of construction land is beneficial for ecological construction and vegetation restoration and reconstruction in the sandstone area of the Yellow River Basin.

The problem of mycotoxin contamination in edible and forage agricultural products has become increasingly serious due to global warming and drought. Vomitoxin, also known as deoxynivalenol (DON), is one of the most common mycotoxins, mainly produced by Fusarium spp. and others, which not only causes great economic losses, but also seriously harms the health of humans and livestock. Mycotoxin de‐ toxification methods mainly include physical, chemical and biological methods, while biological detoxification methods based on microorganisms or enzymes have received more and more attention and application due to the advantages of strong specificity, high efficiency and no secondary pollution. This paper mainly reviews the toxicity of DON and its pathogenic mechanism to animals, as well as the research progress on the application of biological detoxification technology in feeds, aiming to provide reference for the biodetoxification of DON in feeds.

The research progress on simulation and optimization of pressure swing adsorption purification technology for low concentration coal is reviewed. The adsorbent and pressure swing adsorption process are briefly and clearly introduced. From the perspective of the development trend of adsorbents, simulation and optimization can improve the performance of adsorbents and the ratio of raw materials, and improve the effectiveness of adsorbents. From the perspective of the development trend of pressure swing adsorption, simulation and optimization of pressure swing adsorption equipment can make its automation effect better and economic benefit higher. This paper summarizes and points out that simulation and optimization play an important role in this technology from both perspectives, which improves the efficiency and productivity. While bringing a lot of convenience to the technology, there are also areas for further improvement from both perspectives. From the perspective of adsorbent, the simulation and optimization of multicomponent mixtures still need to be improved; from the perspective of pressure swing adsorption, there are still limitations in the dynamic change simulation in the actual operation, and the safety optimization in the operation of the device should be considered more.

Copper (Cu) is a crucial trace metal element in human body, which plays an important role in many life processes. Meanwhile, copper is strictly regulated in the human body and its homeostasis is closely related to the physiological state. The occurrences of many diseases are often accompanied by the copper imbalance. By monitoring the subtle variation in copper homeostasis, it can more accurately identify the factors that lead to abnormal changes in human physiology, especially the impact of environmental factors on the occurrence and development of diseases. In the past two decades, with the development of analytical instruments and improvement of analytical methods, non-traditional stable isotopic analysis has been widely applied in geochemistry and archaeology. Owing to its strong traceability, non-traditional stable isotopic analysis can also provide a new perspective to reveal the mechanisms of element homeostasis imbalance. Especially, stable copper isotopic analysis has a wide application prospect in environmental health research. Because of the virtues of wide application range and high analytical accuracy, multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) has effectively promoted the process of copper isotopic analysis. In this paper, we reviewed the mechanisms of non-traditional stable isotope fractionation and analysis methods of Cu isotopes based on MC-ICP-MS, and the basic conception of mass dependent fractionation (MDF) and non-mass dependent fractionation (MIF) as well as the instrumental configuration of MC-ICP-MS. We also introduced the methods of copper isotopic analysis, and then summarized the main applications of copper isotopic analysis in environmental health research. We focused on two aspects, i.e., Cu isotopic analysis of population characteristics and research on disease indicators. In summarizing the relevant researches of Cu isotopic analysis of population characteristics, we reviewed the influence factors, such as age, gender, dietary habits, and other factors. Afterwards, the studies of copper isotopic analysis on some diseases, such as cancers, nervous diseases, disorders of copper transporters, and other diseases were summarized. Finally, we discussed the application prospects of copper isotopic analysis in environmental health research. Until now, the application of stable copper isotopic analysis in environmental health is still in the initial stage, and there still exist many difficulties and challenges. We primarily list four main difficulties and challenges in future studies, including high-throughput sample analysis, background population investigation, combination of other clinical indicators, and combination of multiple omics techniques.
