[Objective] Rural resettlement areas are the key areas to consolidate the effective connection between poverty alleviation achievements and rural revitalization. Based on the theory of new endogenous development, the analysis of the influencing factors and extension mechanism of the evolution of the agricultural industry chain is of great significance for preventing the return to poverty and promoting rural revitalization in an all-round way. [Methods] Based on the field research data of Tuanjie Village, a typical resettlement area in Ningxia Hui Autonomous Region in 2023, this study used the random forest model to identify the key factors of the evolution of the agricultural industry chain, and further described the extension mechanism of the agricultural industry chain with the help of the actor network theory. [Results] (1) The driving role of village collective organizations, the downstream sales and services of the industrial chain, the planting income of farmers, the age of respondents, the level of education and the proportion of agricultural income had important effects on the evolution of the agricultural industrial chain. (2) The village collective was the key actor in the extension of the agricultural industry chain in Tuanjie Village, and it relied on land, technology, and other resources to recruit, mobilize, and provide feedback to human actors such as the government, farmers’ cooperatives, enterprises, and farmers, and non-human actors such as land, capital, market, and technology, to eliminate objections, forming a relatively stable heterogeneous actor network. (3) In the process of rural industrial development, guided by the reasonable flow and allocation of factors such as people-land-industry-finance between urban and rural areas, the rural economic scale was expanded and the industrial layout was optimized through the fiv drivers of policy guarantee, capacity improvement, service guarantee, capital investment, and product research and development; With agricultural resources as the base of the industrial chain, the extension mechanism of multi-force cooperation and collaboration should be built to realize the orderly extension of the rural agricultural industry chain. [Conclusion] In the process of rural industrial development in resettlement areas, a network of actors with village collective organizations as the core has formed, which provides strong support for the extension of rural agricultural industry chain and promotes the high-quality development of rural industries.

Methionine, cysteine and cystine, which were acetylated at the N‐terminus and methylated at the C‐terminus, react rapidly with the environmental nitrate radical (NO3.) with rate coefficients of 7.7×109, 3.4×109 and 2.0×109 M−1 s−1, respectively, in acetonitrile. Methionine (Ac−Met−OMe) is successively oxidized via the sulfoxide (Ac−MetO−Me) to the sulfone (Ac−MetO2−OMe), with the latter step being also extremely fast with a rate coefficient of 1.2×109 M−1 s−1. Computations predict formation of an initial charge transfer complex between NO3. and the S or SO moiety in Ac‐Met‐OMe, Ac‐MetO‐OMe and cystine (Ac−Cys(S−S)Cys‐OMe), respectively, which is followed by simultaneous S−O bond formation and NO2. expulsion. Calculations for the reaction of cysteine (Ac‐Cys‐OMe) with NO3. revealed side‐chain oxidation to give a thiyl radical or a sulfenic acid as likely pathways. These findings highlight the potential harmful impact of NO2./O3 pollution on S‐containing amino acid residues in peptides. [ABSTRACT FROM AUTHOR]

The development of gastritis is associated with an increased risk of gastric cancer. Current invasive gastritis diagnostic methods are not suitable for monitoring progress. In this work based on 78 gastritis patients and 50 healthy individuals, we observed that the variation of tongue-coating microbiota was associated with the occurrence and development of gastritis. Twenty-one microbial species were identified for differentiating tongue-coating microbiomes of gastritis and healthy individuals. Pathways such as microbial metabolism in diverse environments, biosynthesis of antibiotics and bacterial chemotaxis were up-regulated in gastritis patients. The abundance of Campylobacter concisus was found associated with the gastric precancerous cascade. Furthermore, Campylobacter concisus could be detected in tongue coating and gastric fluid in a validation cohort containing 38 gastritis patients. These observations provided biological evidence of tongue diagnosis in traditional Chinese medicine, and indicated that tongue-coating microbiome could be a potential non-invasive biomarker, which might be suitable for long-term monitoring of gastritis.

Reclamation of industrial and mining wasteland can help to address the current urgent challenge of land resource needs in China. In order to ensure well-developed reclamation planning, a large number of field surveys of industrial and mining wasteland were undertaken in Daye County, which is located in the south-east of Hubei province. Through a series of indexes, the reclamation potential of the industrial and mining wasteland was determined. Based on the surveys and evaluation, a specific reclamation plan was then produced, and it is shown on four major maps, which are the industrial and mining wasteland status map, the reclamation planning map, the reclamation potential distribution map, and the major reclamation project distribution map. The scale of the first two maps is 1:250,000, and the scale of the latter two maps is 1:300,000. The main purpose of this project is to provide a detailed planning scheme for local government, which will assist with important decision making in land-use policy, and to provide a unique perspective and experience for scholars all over the world.
