Muscovite^(40)Ar/^(39)Ar isotopic dating of pegmatite veins in the Bieyesamas rare metal deposit in the Altay Mountain,Xinjiang,northwestern China

1.Objective The Altay Orogenic Belt in Xinjiang,China is located in the west of the Central Asian Orogenic Belt and in the transition zone between the Siberian Plate and the Kazakhstan-Junggar Plate,extending approximately 500 km in northern Xinjiang,China(Fig.1a).The Altay Orogenic Belt has undergone two-way accretion of the Paleozoic crust and the Meso-Cenozoic intracontinental orogeny,leading to the formation of large numbers of intermediate-acid intrusions.More than 100000 pegmatite veins have been discovered in the intermediate-acid intrusions,and they constitute an important rare metal metallogenic belt of China(Fig.1b).

LA-ICP-MS zircon U-Pb dating of tuffites in the Sachakou Pb-Zn mining area, Karakorum, Xinjiang and its establishment of Early Triassic strata

1.Objective In the past decade,a group of medium to giant lead-zinc deposits,represented by Huoshaoyun,Sachakou,and Yuanbaoling,have been discovered in the Aksai Chin region of Karakoram,Xinjiang.They are all located in the Mesozoic carbonate and clastic rock formations.The Sachakou leadzinc mining area is adjacent to the northwest of the Huoshaoyun lead-zinc mining area and is in the same stratigraphic layer as Huoshaoyun.Although many scholars have been arguing about the type and age of Huoshaoyun lead-zinc mineralization,few scholars have paid attention to the classification of the ore-bearing strata in the area.The stratigraphy of the Lower Permian Shenxianwan Group to the Upper Cretaceous Tielongtan Group is exposed in the Sachakou area of Karakorum,Xinjiang,however,the Late Permian-Early Triassic stratigraphy is missing(Fig.1a).Due to the harsh natural conditions in the area and the low level of work,the stratigraphic delineation is not exhaustive,and the regional lithology is dominated by carbonates and clastic rocks,which makes it difficult to identify the age of the regional lithology and causes problems for the exploration and research of lead-zinc in the area.

A new small baurioid therocephalian from the Lower Triassic Jiucaiyuan Formation, Xinjiang, China

Several therocephalian species,mainly represented by cranial material from the late Permian,have been reported from China in recent years.Here we describe a tiny new baurioid therocephalian,Jiucaiyuangnathus confusus gen.et sp.nov.,from the Jiucaiyuan Formation,Xinjiang,China.The new taxon is represented by a partial snout with occluded partial lower jaw and two postcranial skeletons.Although juvenile in stage,the new species is diagnosed by the following features:round pit in middle of lateral surface of maxilla;lacrimal contact nasal;fossa for dentary tooth on the posterior end of the premaxilla,lateral to the anterior choana;two small vertical triangular ridges extending dorsally and ventrally on the vomerine anterior portion,and bordering a thin vomerine foramen laterally;anterior projection of the lateral part of the frontal on the nasal;symphyseal region of the dentary projected anteriorly;5 upper premaxillary teeth,upper and lower canines absent,diastema between the last premaxillary upper incisor and first maxillary tooth present,no diastema separating anterior from posterior dentition in the mandible,10 maxillary teeth and 12 dentary teeth,posterior postcanine expands mesiodistally,having a main large cusps and tiny anterior and posterior accessory cusps in line;neural arches of the atlas fused by the neural spine,neural spine of the axis projected posteriorly,procoracoid foramen lies between procoracoid and scapula.Features of the dentition resembles those of the small baurioid Ericiolacerta parva from South Africa and Silphedosuchus orenburgensis from Russia.The specimens provide the rare opportunity to know in detail the postcranial skeleton of baurioids.

Spatiotemporal variation of land surface temperature and its driving factors in Xinjiang,China

Land surface temperature(LST) directly affects the energy balance of terrestrial surface systems and impacts regional resources, ecosystem evolution, and ecosystem structures. Xinjiang Uygur Autonomous Region is located at the arid Northwest China and is extremely sensitive to climate change. There is an urgent need to understand the distribution patterns of LST in this area and quantitatively measure the nature and intensity of the impacts of the major driving factors from a spatial perspective, as well as elucidate the formation mechanisms. In this study, we used the MOD11C3 LST product developed on the basis of Moderate Resolution Imaging Spectroradiometer(MODIS) to conduct regression analysis and determine the spatiotemporal variation and differentiation pattern of LST in Xinjiang from 2000 to 2020. We analyzed the driving mechanisms of spatial heterogeneity of LST in Xinjiang and the six geomorphic zones(the Altay Mountains, Junggar Basin, Tianshan Mountains, Tarim Basin, Turpan-Hami(Tuha) Basin, and Pakakuna Mountain Group) using geographical detector(Geodetector) and geographically weighted regression(GWR) models. The warming rate of LST in Xinjiang during the study period was 0.24℃/10a, and the spatial distribution pattern of LST had obvious topographic imprints, with 87.20% of the warming zone located in the Gobi desert and areas with frequent human activities, and the cooling zone mainly located in the mountainous areas. The seasonal LST in Xinjiang was at a cooling rate of 0.09℃/10a in autumn, and showed a warming trend in other seasons. Digital elevation model(DEM), latitude, wind speed, precipitation, normalized difference vegetation index(NDVI), and sunshine duration in the single-factor and interactive detections were the key factors driving the LST changes. The direction and intensity of each major driving factor on the spatial variations of LST in the study area were heterogeneous. The negative feedback effect of DEM on the spatial differentiation of LST was the strongest. Lower latitudes, lower vegetation coverage, lower levels of precipitation, and longer sunshine duration increased LST. Unused land was the main heat source landscape, water body was the most important heat sink landscape, grassland and forest land were the land use and land cover(LULC) types with the most prominent heat sink effect, and there were significant differences in different geomorphic zones due to the influences of their vegetation types, climatic conditions, soil types, and human activities. The findings will help to facilitate sustainable climate change management, analyze local climate and environmental patterns, and improve land management strategies in Xinjiang and other arid areas.

Research progress of local characteristic drugs for treatment of rheumatoid arthritis in Xinjiang

Rheumatoid arthritis(RA)is a systemic autoimmune disease characterized by synovitis.This disease tends to recur,persist,and is difficult to cure.The pathogenesis of RA is complex.Currently,the commonly used treatments for RA—non-steroidal anti-inflammatory drugs(NSAIDs),disease-modifying anti-rheumatic drugs(DMARDs),glucocorticoids,and immunosuppressants—have notable side effects with long-term use and may be ineffective for some patients.Therefore,it is crucial to find drugs with limited side effects and significant curative effects.Xinjiang's local characteristic drugs have a long history,abundant resources,and are known for their safety and effectiveness in treating RA.In recent years,many studies have reported on the mechanisms of action and therapeutic effects of Xinjiang's local characteristic drugs on RA.This article reviews the pathogenesis of RA,as well as the research progress and treatment characteristics of Xinjiang-featured drugs.

Spatial-temporal Coupling Analysis of Economic Development-Social Development-Government Governance in Xinjiang, China

High-quality development of ethnic minority areas is a key issue in China’s economic and social transformation.In order to explore the development trend and optimization path of high-quality development in ethnic minority areas,this study constructed a systematic evaluation index system of economic development,social development and government governance.The coupled coordination model was adopted to quantitatively analyze the spatio-temporal evolution characteristics of economic development,social development and government governance in Xinjiang from 2013 to 2020.The influencing factors of coupling coordination development of the three systems were identified by grey correlation analysis.The spatial-temporal pattern analysis results show that the coupling coordination degree of Xinjiang increased steadily,but the regional differences gradually expanded.The coupling coordination degree shows a stable structure with high center and low periphery,and a spatial pattern of low in southern Xinjiang and high in northern Xinjiang.The results of grey correlation analysis show that the grey correlation degree among economic development,social development and government governance in Xinjiang is above 0.78.The three systems of economic development,social development and government governance interact with each other,forming a complex system of high-quality development in ethnic minority areas.To promote highquality development in Xinjiang,it should take social stability and long-term stability as the overall goal,improve the quality of the production and living environment on the basis of economic development,enhance regional economic competitiveness,and take government governance as a means to optimize the environment for regional development.

Intellectual Property Protection and New Development Pattern Construction of Xinjiang Jujube

"Three new developments"is the guiding ideology of Chinese-style high-quality development in the new era.Jujube(Zizyphus jujube Mill.)is a plant of Zizyphus of Rhamnaceae,which originated in China and has been listed as one of the"five fruits"since ancient times.Xinjiang is the most important jujube producing area in China,and its yield has accounted for 50%of the national jujube yield.In the five prefectures and cities of southern Xinjiang,as well as the regimental farms of southern and eastern Xinjiang of Xinjiang Production and Construction Corps,the jujube industry is an advantageous characteristic industry in agriculture.This paper studied Xinjiang jujube industry and its agricultural intellectual property resources,analyzed six major issues to be further implemented,such as the"three new developments"thinking and the strategy of building an intellectual property power,and puts forward eight strategies such as coordinating the two markets and two resources to accelerate the construction of a new development pattern and dual circulation of jujube.

Japan's State Strategy vs. Anti-Terrorism

The September 11 event upset Japan’s diplomatic agenda and ushered in a strategic restructuring with the focus on anti-terrorism and the top priority given to ties with Washington. Its new diplomacy against terror stresses three aspects: policy towards Washington for ensuring strategic center

On the Conflict and Balance Between Anti-terrorism and Protection of Human Rights

With the increasingly serious global terrorism situation,all countries have continuously revised their anti-terrorism laws and related criminal laws,adopting legislation to restrict and derogate civil liberties,increased the punishment for terrorists,and adopted corresponding anti-terrorism measures to increase monitoring of suspicious persons.In this context,conflicts and contradictions in human rights protection and the fight against terrorism often arise.The Xinjiang uygur Autonomous Region is at the forefront of China’s anti-terrorism efforts.Facing the special situation of dealing simultaneously with the slowdown in economic growth,making difficult structural adjustments,and absorbing the effects of the previous economic stimulus policies,since 2014,the local government of Xinjiang has adopted a combination of measures on anti-terrorism and de-extremism work and achieved significant results under the correct guidance of the strategy of governance in Xinjiang proposed by the central government.The most important consideration of anti-terrorism lies in the analysis Chinese and Western human rights values,coordinate and balance the relationship between anti-terrorism and human rights protection within the existing legal framework.

Urban Spatial Carrying Capacity and Sustainable Urbanization in the Middle-east Section of North Slope of Kunlun Mountains in Xinjiang,China

Urban spatial carrying capacity is the comprehensive support capacity of natural resources for urban development,which is of great significance in guaranteeing the sustainable urbanization.The middle-east section of North Slope of Kunlun Mountains in Xinjiang,China,is characterized by harsh climate and sparse population,whereas it is important for the initiative of the new Silk Road Belt because of its important location.Cities in this area have begun to take shape,and the implementation of the Silk Road Belt Initiative will inevitably stimulate the urbanization in this area.The extent to which the cities in this area will be supported by natural resources and how to fulfill the requirements of sustainable socioeconomic development needs to be investigated.In view of this,the present study evaluated the urban spatial carrying capacity and discussed feasible approaches that could support the sustainable urbanization in this area.The results show that 97.59%of the study area belongs to the low and relatively low levels of spatial carrying capacity for urban construction,and the area of medium,relatively high and high levels is 1.12×104 km2,accounting for 2.41%of the total study area,mainly distributed in small clusters in the central alluvial fan oasis plains.Resource and environmental factors highly constrain urban construction,and low spatial matching of land and water resources,harsh climatic conditions and high risk of geological disasters are three major shortcomings.In addition,lagging transportation infrastructure construction and the resulting weak internal and external spatial connections also affect urban development.On this basis,the scientific arrangement of urban distribution,steady promotion of regional economic development based on local characteristics,further improvement of transportation infrastructure construction and strengthening the cooperation between the Xinjiang Production and Construction Corps and local governments are suitable approaches for sustainable urbanization in the study area.

The Relationship Between Anti-terrorism and Human Rights Protection: Perspective of International Politics

This article briefly outlines how anti-terrorism struggles became linked and their relationship thereafter with human rights issues in international political life. With equal relevance and value to human development, anti-terrorism efforts and human rights protection are themselves not mutually exclusive or contradictory. Their conflict in everyday life has sometimes resulted from the fact that they are both manipulated in the service of certain political ends. What's more, there has never been p erfect human rights protection in the world so far, which often makes human rights problems an easy charge against almost every government. No anti-terrorist activities in either the US or Europe have been really constrained by the idea of human rights no matter how beautiful their rhetoric has been. Now both human rights and anti-terrorism have been made into a tool of diplomacy and international politics. With the war in Afghanistan over, the United States is enhancing its human rights diplomacy together with its anti-terrorism diplomacy. Truly efficient, comprehensive international cooperation on anti-terrorism is still far away.

Anti-terrorism and Human Rights Protection: Africa in Perspective

The relation between Anti-terrorism and human rights Protection is rather complicated. Based on the practices in Africa, this article analyses the conflicts and contradictions between the two. While countering terrorism, governments have to take the duty of human rights protection as well. Rights are of key importance in preventing and countering terrorism. Integrating human rights construction into antiterrorism mechanism is rather helpful in eliminating various moods of dissatisfaction which are easy to breed terrorism.

Helicobacter pylori infection in Xinjiang Uyghur Autonomous Region:Prevalence and analysis of related factors

BACKGROUND^(14)C urea breath test(^(14)C UBT)and immunohistochemical staining(IHC)are widely used for detection Helicobacter pylori(H.pylori)infection with different sensitivity,and there is a difference in H.pylori infection rate in Uyghur and Han ethnic groups.Both need large cohort studies to evaluate the differences more accurately.AIM To analyze the difference between^(14)C UBT and IHC for H.pylori detection in Xinjiang Uyghur Autonomous Region and the difference between Uyghur and Han populations.METHODS There were 3944 cases of H.pylori infection detected by both IHC and^(14)C UBT at the same time(interval<1 wk,with sampling site including gastric antrum,selected from 5747 patients).We compared the sensitivity of^(14)C UBT and IHC.We also compared 555 pairs of Han/Uyghur cases(completely matched for gender and age)for their H.pylori infection rates.The overall H.pylori infection rate of all 5747 cases and the correlation with other clinicopathological data were also further analyzed.SPSS V23.0 software was used for statistical analysis.RESULTS The sensitivity was 94.9%for^(14)C UBT and 65.1%for IHC,which was a significant difference(n=3944,P<0.001).However,among those cases negative for H.pylori by^(14)C UBT(detection value≤100),4.8%were positive by IHC.Combining both methods,the overall H.pylori infection rate was 48.6%(n=5747),and differences in gender,age group,ethnicity and region of residence significantly affected the H.pylori positive rates.According to age group(Han/Uyghur),the positive rates were≤30 years(62.2%/100.0%),31-40 years(45.2%/85.7%),41-50 years(47.2%/79.2%),51-60 years(44.6%/76.1%),61-70 years(40.9%/68.2%),71-80 years(41.7%/54.1%)and≥81 years(42.9%/NA).The H.pylori infection rates of Han/Uyghur paired cases were 41.4%and 73.3%,which was a significant difference(P<0.001)(555 pairs).H.pylori positivity was significantly related to moderate-severe grade 2-3 chronic/active gastritis and intestinal metaplasia(all P<0.05).CONCLUSION The sensitivity of^(14)C UBT was significantly higher,but combined application can still increase the accuracy.The prevention H.pylori should be emphasized for Uygur and young people.
