Study on genetic characteristics of Cryptosporidium isolates and first report of C. parvum IIdA24G2 subtype in dairy cattle in China.

Cryptosporidium is an important gastrointestinal parasite that can cause mild to severe diarrhea in various vertebrates, including humans and domestic animals. Infection is prevalent in dairy cattle, particularly calves, resulting in diarrhea and increased mortality with significant production losses. However, the prevalence and identity of Cryptosporidium spp. in cattle in Heilongjiang Province is still poorly known. Our study aimed to investigate the prevalence and species and subtype distribution of Cryptosporidium in cattle in the region. In addition, we evaluated the zoonotic potential of Cryptosporidium isolates and assessed possible transmission routes and health effects of this organism. We collected 909 fecal samples from five different farms in Heilongjiang Province between August and September 2022. The samples underwent Cryptosporidium detection by nested PCR and small subunit (SSU) rRNA gene sequence analysis. Four Cryptosporidium species were identified, including C. parvum, C. bovis, C. ryanae, and C. andersoni, with an overall prevalence of 4.4% (40/909). Based on sequence analysis of the 60 kDa glycoprotein gene of C. parvum and C. bovis, three subtypes of C. parvum were identified, namely two previously known subtypes (IIdA19G1 and IIdA20G1), and one novel subtype (IIdA24G2). Two distinct subtype families were identified in C. bovis (XXVId and XXVIe). The high diversity of Cryptosporidium in dairy cattle and the emergence of a novel subtype of C. parvum in Heilongjiang Province suggest that dairy cattle may serve as a significant source of zoonotic cryptosporidiosis infection in this region.

Quantitative Evaluation of Digital Economy Policy in Heilongjiang Province of China Based on the PMC-AE Index Model

The digital economy has gradually become an important support for high-quality economic development, but the speed of digital economy development is affected by policies. A reasonable digital economy policy system has practical significance for the development of the digital economy. This study takes the digital economy policy text published by Heilongjiang Province from 2015 to 2022 as the research object, uses the method of text mining and content analysis, innovatively introduces AE automatic coding technology into the PMC index model, constructs the PMC-AE index model, and quantitatively evaluates and analyzes the policy text. The study found that the digital economy policy of Heilongjiang Province is at a good level as a whole, but there is still room for improvement. The digital economy policy of Heilongjiang Province is mainly based on guiding policies. The richness of policy types, participants, and incentives is insufficient. The limitation of policy timeliness is strong, and the cooperation of the issuing agencies is not sufficient. Based on the research results, it is suggested that policymakers should pay attention to the combination of macro and micro policies, promote multi-agent participation, enrich incentive measures, develop both policy guidance and supervision, improve the timeliness and consistency of policies, and strengthen the communication between the Issuing Departments. In addition, this study puts forward policy suggestions for specific government departments from four aspects of digital industrialization, industrial digitization, digital governance, and data value. This study not only provides policy recommendations for policymakers but also expands the field of policy evaluation.

Dynamic assessment of community resilience in China: empirical surveys from three provinces.

Strengthening the construction of community resilience and reducing disaster impacts are on the agenda of the Chinese government. The COVID-19 pandemic could alter the existing community resilience. This study aims to explore the dynamic change trends of community resilience in China and analyze the primary influencing factors of community resilience in the context of COVID-19, as well as construct Community Resilience Governance System Framework in China. A community advancing resilience toolkit (CART) was used to conduct surveys in Guangdong, Sichuan, and Heilongjiang provinces in China in 2015 and 2022, with community resilience data and information on disaster risk awareness and disaster risk reduction behaviors of residents collected. The qualitative (in-depth interview) data from staffs of government agencies and communities (n = 15) were pooled to explore Community Resilience Governance System Framework in China. Descriptive statistics analysis and t-tests were used to investigate the dynamic development of community resilience in China. Hierarchical regression analysis was performed to explore the main influencing factors of residential community resilience with such socio-demographic characteristics as gender and age being controlled. The results indicate that community resilience in China has improved significantly, presenting differences with statistical significance (p < 0.05). In 2015, connection and caring achieved the highest score, while disaster management achieved the highest score in 2022, with resources and transformative potential ranking the lowest in their scores in both years. Generally, residents presented a high awareness of disaster risks. However, only a small proportion of residents that were surveyed had participated in any "community-organized epidemic prevention and control voluntary services" (34.9%). Analysis shows that core influencing factors of community resilience include: High sensitivity towards major epidemic-related information, particular attention to various kinds of epidemic prevention and control warning messages, participation in epidemic prevention and control voluntary services, and formulation of epidemic response plans. In this study, we have constructed Community Resilience Governance System Framework in China, which included community resilience risk awareness, community resilience governance bodies, community resilience mechanisms and systems. During the pandemic, community resilience in China underwent significant changes. However, community capital was, is, and will be a weak link to community resilience. It is suggested that multi-stages assessments of dynamic change trends of community resilience should be further performed to analyze acting points and core influencing factors of community resilience establishment at different stages.

Recognition and rejection of foreign eggs of different colors in Barn Swallows

Brood parasitic birds lay eggs in the nests of other birds, and the parasitized hosts can reduce the cost of raising unrelated offspring through the recognition of parasitic eggs. Hosts can adopt vision-based cognitive mechanisms to recognize foreign eggs by comparing the colors of foreign and host eggs. However, there is currently no uniform conclusion as to whether this comparison involves the single or multiple threshold decision rules. In this study, we tested both hypotheses by adding model eggs of different colors to the nests of Barn Swallows (Hirundo rustica) of two geographical populations breeding in Hainan and Heilongjiang Provinces in China. Results showed that Barn Swallows rejected more white model eggs (moderate mimetic to their own eggs) and blue model eggs (highly non-mimetic eggs with shorter reflectance spectrum) than red model eggs (highly non-mimetic eggs with longer reflectance spectrum). There was no difference in the rejection rate of model eggs between the two populations of Barn Swallows, and clutch size was not a factor affecting egg recognition. Our results are consistent with the single rejection threshold model. This study provides strong experimental evidence that the color of model eggs can has an important effect on egg recognition in Barn Swallows, opening up new avenues to uncover the evolution of cuckoo egg mimicry and explore the cognitive mechanisms underlying the visual recognition of foreign eggs by hosts.

Detection and phylogenetic classification of Neoehrlichia mikurensis in rodents from the region of Liupan Mountain, China.

Neoehrlichia mikurensis (N. mikurensis) is an emerging tick-borne pathogen that can cause neoehrlichiosis. Rodents are considered the major host for N. mikurensis. Currently, N. mikurensis has been detected in rodents in several studies from China and other countries. However, no research on N. mikurensis infection in rodents has been reported in the Liupan mountain region. The region of Liupan Mountain, located in northwestern China, is the center of the triangle formed by the cities of Xi'an, Yinchuan, and Lanzhou, with multiple tourist sites in the region. To survey whether there is N. mikurensis in hosts, rodents were captured in this region in September 2020. A nested polymerase chain reaction was used to detect the DNA of N. mikurensis, followed by nucleotide sequencing and phylogenetic analysis. In the region, among 88 rodents, 3 rodents were detected positive for N. mikurensis, a detection rate of 3.4%. Based on phylogenetic analysis of the partial groEL gene sequences, N. mikurensis from rodents in Liupan Mountain clustered in the same evolutionary branch with those found in rodents from Japan, Russia, and northeastern China, and also in ticks and clinical cases from Heilongjiang Province in northeastern China.

Identification of Heilongjiang crossbred beef cattle pedigrees and reveals functional genes related to economic traits based on whole-genome SNP data.

Introduction: To enhance the beef cattle industry, Heilongjiang Province has developed a new Crossbred beef cattle variety through crossbreeding with exotic commercial breeds. This new variety exhibits relatively excellent meat quality, and efficient reproductive performance, catering to market demands. Method: This study employed whole genome resequencing technology to analyze the genetic pedigree and diversity of 19 Heilongjiang Crossbred beef cattle, alongside 59 published genomes from East Asian, Eurasian, and European taurine cattle as controls. In addition, genes related to production traits were also searched by identifying Runs of Homozygosity (ROH) islands and important fragments from ancestors. Results: A total of 14,427,729 biallelic SNPs were discovered, with the majority located in intergenic and intron regions and a small percentage in exon regions, impacting protein function. Population genetic analyses including Principal Component Analysis (PCA), Neighbor-Joining (NJ) tree, and ADMIXTURE identified Angus, Holstein, and Mishima as the main ancestors of Crossbred beef cattle. In genetic diversity analysis, nucleotide diversity, linkage disequilibrium, and inbreeding coefficient analysis reveal that the genetic diversity of Crossbred beef cattle is at a moderate level, and a higher inbreeding coefficient indicates the need for careful breeding management. In addition, some genes related to economic traits are identified through the identification of Runs of Homozygosity (ROH) islands and important fragments from ancestors. Conclusion: This comprehensive genomic characterization supports the targeted improvement of economically important traits in Crossbred beef cattle, facilitating advanced breeding strategies.

Geochronology and geochemistry of granitoids of the Yanghuidongzi porphyry Cu deposit, Heilongjiang Province: Implications for petrogenesis and metallogenic setting during the Early Jurassic in the Northeast of China

AbstractThe Yanghuidongzi Cu deposit is a newly discovered porphyry Cu deposit in the eastern segment of the Central Asian Orogenic Belt. The Cu mineralization is associated with granodiorite porphyry and granodiorite. This paper presents new zircon U–Pb dating, Hf–O isotopes, whole‐rock major and trace elements data for this deposit, to constrain the ore‐forming age and the magma source of the granitoids. LA–ICP–MS U–Pb dating of zircons from granodiorite porphyry and granodiorite samples yielded ages of 192.8 ± 1.7 Ma, and 198.1 ± 1.4 Ma, respectively, which are interpreted as the emplacement ages of granitoids. These age data confirm that the granodiorite porphyry is associated with the porphyry Cu deposit, and both granitic intrusion and Cu mineralization were associated with the Early Jurassic magmatism in NE China. The granodiorite porphyry has high SiO2, Al2O3, and Sr contents together with low concentrations of Y and Yb. It is enriched in LILE, and depleted in HFSE, classified as adakitic. The granodiorite has high SiO2 and K2O, enriched in LILE, depleted in HFSE, and is classified as high‐K calk‐alkaline I‐type granite. The granodiorite porphyry and granodiorite have variable εHf(t) values (5.2 to 9.5), Mesoproterozoic two‐stage Hf models (TDM2) of 629–905 Ma, and δ18O values (4.26‰ to 7.50‰). These geochemical data and zircon Hf–O isotopes suggest that the granodiorite porphyry originated from the partial melting of thickened juvenile crustal materials and granodiorite derived from the partial melting of juvenile crustal materials with an additional of mantle‐derived magmas input. Combining our new data with the regional tectonic setting, the Yanghuidongzi Cu deposit and the related granitoids formed in a compressional tectonic setting associated with the subduction of the Paleo–Pacific Plate beneath the Eurasian continent.

Construction of Traditional Village Health Development Evaluation System Based on Ecological and Cultural Health Theory

Abstract Traditional villages, as spatial carriers with rich cultural resources, are important cornerstones for cultural inheritance and promotion, and their ecological and cultural symbiosis has been formed in the process of long historical development, which contains rich ecological wisdom. To comprehensively analyze the development status of traditional villages and plan and design future development, this study is guided by the theory of ecological and cultural health, selects the evaluation elements of the target level, criterion level, and indicator level, and devotes itself to constructing an evaluation system of the healthy development of traditional villages, and applies the hierarchical analysis method and the entropy weight method to determine the index weight, to establish a comprehensive evaluation model of the healthy development of traditional villages. By evaluating the healthy development of traditional villages in Ning’an City, Mudanjiang City, and Heilongjiang Province, the study verifies the feasibility of the evaluation system constructed by the study for the healthy development of traditional villages. It proposes corresponding healthy development strategies for the evaluation analysis to provide reference ideas for traditional villages’ ecological and cultural health and sustainable development.

Regional differences, distributional dynamics and convergence of multidimensional food security levels in China.

Food security is one of the important issues in the current world development process. The article takes 31 provinces (districts and cities) in China as the research object and constructs a multidimensional food security level evaluation index system from four dimensions: quantitative security, nutritional security, ecological security, and capacity security. Using the entropy method, China's food security index was calculated for the ten-year period from 2013 to 2022. Overall, China's food security level showed an upward trend during the decade, with the provinces of Shandong, Heilongjiang, and Henan having the highest level of security. The distribution dynamics of food security and its spatiotemporal evolution in the seven regions were examined using the Dagum Gini coefficient and its decomposition, and the absolute and conditional convergence of food security in the different areas was verified. The results of the study show that the provinces within East China have the largest gap in food security levels between them, and there is absolute β-convergence. Looking at China as a whole, the development of its food security level is characterized by significant convergence, which means that provinces with a low level of food security will have a faster rate of growth than those with a high level of food security, resulting in a gradual narrowing of the gap in food security levels between provinces.

Семеновы-Знаменские в Харбине. Материалы к биографии

Continuity of generations is a very serious issue for Harbin residents. Harbin residents have always tried to preserve the memory of their ancestors. Preserving the history of Russian emigration has a high relevance of the problem. The history of many Russian families is connected with Harbin, where there was the largest Russian diaspora. Nowadays this city is the administrative center of the Chinese province of Heilongjiang. We should not forget about the people who built the Chinese Eastern Railway, as well as about the Russian emigrants who lived in Harbin, but kept the image of Russia in their hearts and contributed enough to Russian culture and science. The purpose of this paper is to study the Russian emigrants life in Harbin and to restore contact with their descendants. The article uses historical and system analysis and bibliographic research method. The paper tells about the amazing life of Nikolai Nikolaevich Znamensky: his childhood in Harbin, his relatives, his move to the USSR, his admiration of nowadays China, and also focuses on the message of Nikolai Nikolaevich Znamensky to modern Harbin residents.

Православие в Китае: интерпретация работ китайских философов

The topic of Russian Orthodoxy and the history of Orthodoxy in China are being analyzed by Chinese researchers again today. The strategy of Chinese-Russian relations explains this interest. It is aimed at equal dialogue, based on understanding each other. Chinese researchers have long come to the conclusion that it is possible to understand the Russian character only when you study the culture of the peoples of Russia and the Russian mentality. They continue to study the history of the Orthodox Church in China. They use the historical-descriptive method and form the dynamics of this process. They study the history of the Orthodox Church in China through an analysis of political processes in Russia and China. Heilongjiang Province remains the most prominent focus of this study. China's ethnic culture policy is the next direction of this research. Chinese scientists in these studies study ethnic minority religions. They are researching their cultures. This direction is becoming a priority. Its necessity is associated with the formation of the concept of national culture. The purpose of this article was the following. The authors had to substantiate the approaches that were formed in Chinese philosophy and religious studies for the study of the Orthodox Church in China. The authors turned to the interpretative method, a comparative analysis of authentic sources that are not represented in the works of Russian scientists.
