Leye County was identified as a pilot for integrating green development and reform in Guangxi in 2021. The government aims to systematically explore and implement green development while advancing the development of the county. In this study, comprehensive research at a grassroots level was conducted. First, this study analyzed problems faced during the delivery of green reform in Leye County. Then, solutions that foster comprehensive green economic and social development in Leye County were summarized. The proposed solutions promote a system that integrates green development and reform in Leye County with systematic optimization and integrated thinking approaches, which will support the effective implementation of reform measures and maximize its overall effect. Specifically, these solutions take ecological advantages as a starting point and create a modern green industrial system with advanced technology, high economic benefits, low resource consumption, and low environmental pollution to promote green development. In terms of developmental policy, this study also puts forward some suggestions for strengthening the management functions of a green government, including optimizing the management of innovative green talent, boosting returns on investments, advancing green reform, initiating green industrial projects, developing clean energy, and broadening green infrastructure. This study provides suggestions for establishing a model in which government, society, enterprises, and citizens participate jointly, and proposes principles and a vision for the future green development of the county.

Objective: To investigate the relationship between serum myeloperoxidase (MPO) level and contrast-induced acute kidney injury (CI-AKI) and prognosis in patients undergoing emergency percutaneous coronary intervention (PCI) and its predictive value.Methods: 381 patients with acute myocardial infarction who underwent emergency PCI in The Second Affiliated Hospital of Anhui Medical University from March 2020 to February 2021 were selected. The clinical data were collected and the serum MPO level was detected within 12 hours before operation. According to the occurrence of CI-AKI after operation, they were divided into CI-AKI group (n=34)and non CI-AKI group (n=347). Multivariate Logistic regression was used to analyze the influencing factors of the incidence of CI-AKI in patients undergoing emergency PCI, and receiver operating characteristic (ROC) curve was used to evaluate the effectiveness of MPO in predicting CI-AKI. According to the best cutoff value, the patients were divided into high MPO group and low MPO group, and the patients were followed up for 12 months. The cumulative incidence of major adverse cardiovascular events (MACE) in high MPO group and low MPO group were analyzed by Kaplan-Meier survival curve. Results: The proportion of combined hypertension, diabetes mellitus, hyperlipidemia and smoking history proportion in CI-AKI group were higher than those in non CI-AKI group, and MPO level, creatinine level, contrast agent dosage were higher than those in non CI-AKI group (P＜0.05). Multivariate Logistic regression analysis showed that diabetes mellitus, high MPO and creatinine level were the risk factors influencing the occurrence of CI-AKI after emergency PCI (P＜0.05). ROC curve analysis showed that the area under the curve (AUC) of preoperative serum MPO level in predicting CI-AKI after emergency PCI was 0.726, and the optimal cut-off value was 491.12 μg/L, with a sensitivity of 58.80%, and specificity of 76.50%. A total of95 cases of MACE occurred one year after operation, with an incidence of 24.93%. Kaplan-Meier survival curve showed that the incidence of MACE in high MPO group was 27.37% higher than that in low MPO group 22.77% (P＜0.05). Conclusion: The serum MPO level of patients with CI-AKI after emergency PCI significantly increased, which is associated with the prognosis of patients, and it is a risk factor for CI-AKI, with high specificity, which can be an effective auxiliary indicator for predicting the occurrence of CI-AKI after emergency PCI.

Most of the main oilfields in China have entered the middle and late stage of exploitation, and its exploitation difficulty has further increased. Microbial oil recovery technology has the advantages of low cost, high efficiency, green and environmental protection, and has a wide application prospect in further enhancing oil recovery of remaining oil. Due to the lack of understanding of reservoir microbial community structure and the long selection cycle of activator formula, the field popularization and application of microbial oil displacement technology is limited. By analyzing the difference of community structure in the reservoir and the interaction between environmental factors and dominant bacteria, basic data and theoretical guidance were provided for directional activation of reservoir microorganisms. The reservoir high-throughput sequencing data were analyzed by species composition analysis, species diversity analysis, principal coordinate analysis (PCoA) analysis and redundancy analysis. The results show that the species composition difference between water injection wells and production wells in Oilfield A is large, and the species composition difference between water injection wells and production wells in Oilfield L is not obvious; In terms of species abundance, species average and species diversity, there is no obvious difference between a oilfield and l oilfield; However, in terms of species similarity between water injection wells and production wells based on genus level, oilfield a shows low similarity, while oilfield L shows high similarity. In the analysis of environmental factors, the microbial community in L oilfield is significantly correlated with salt content, while the microbial community composition in a oilfield is significantly correlated with temperature, pH and SO2- 4 concentration [ABSTRACT FROM AUTHOR]

Target detection algorithms under big data often have the problem of missed target detection and repeated detection. To solve this problem, Mask RCNNAT-NMS algorithm based on AT-NMS is proposed. Firstly, a deformable convolution module is added on the basis of ResNet to enhance the ability to extract multi-layer convolution features of the target. Secondly, the AT-NMS algorithm is used to extract the in-depth information of the candidate target area in the RPN (Regional Candidate Network) stage. Thirdly, the positioning of the target is more accurate through two quantitative processing of ROI Align. Finally, three branches are used to achieve target instance segmentation, target classification and target border regression. The experimental results on the PASCAL-VOC2012 and Indoor CVPR_09 data sets show that, compared with the mask RCNN algorithm, the Mask RCNNAT-NMS algorithm reduces the repeated detection rate and the target missed detection rate, and improves the recognition accuracy. It can be seen that Mask RCNNAT-NMS algorithm can alleviate the problem of target missing and repeated detection caused by fixed threshold, and improve the detection accuracy on this basis.
