4Transplantation of UC-MSCs on collagen scaffold activates follicles in dormant ovaries of POF patients with long history of infertility显示文摘Premature ovarian failure(POF) is a refractory disease for clinical treatment with the goal of restoring fertility. In this study,umbilical cord mesenchymal stem cells on a collagen scaffold(collagen/UC-MSCs) can activate primordial follicles in vitro via phosphorylation of FOXO3 a and FOXO1. Transplantation of collagen/UC-MSCs to the ovaries of POF patients rescued overall ovarian function, evidenced by elevated estradiol concentrations, improved follicular development, and increased number of antral follicles. Successful clinical pregnancy was achieved in women with POF after transplantation of collagen/UC-MSCs or UC-MSCs. In summary, collagen/UC-MSC transplantation may provide an effective treatment for POF.Lijun Ding Guijun Yan Bin Wang Lu Xu Yan Gu Tong Ru Xiaoying Cui Lei Lei Jingyu Liu Xiaoqiang Sheng Bin Wang Chunxue Zhang Yanjun Yang Ruiwei Jiang Jianjun Zhou Na Kong Feifei Lu Huaijun Zhou Yannan Zhao Bing Chen Yali Hu Jianwu Dai Haixiang Sun 2018Science China(Life Sciences)2018,61,12:43
5Transplantation of collagen scaffold with autologous bone marrow mononuclear cells promotes functional endometrium reconstruction via downregulating ΔNp63 expression in Asherman's syndrome显示文摘Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS.Guangfeng Zhao Yun Cao Xianghong Zhu Xiaoqiu Tang Lijun Ding Haixiang Sun Juan Li Xinan Li Chenyan Dai Tong Ru Hui Zhu Jingjie Lu Caimei Lin Jingmei Wang Guijun Yan Huiyan Wang Lei Wang Yimin Dai Bin Wang Ruotian Li Jianwu Dai Yan Zhou Yali Hu 2017Science China(Life Sciences)2017,60,4:39
6Diagnosis and treatment of polypoid lesions of the gallbladder:report of 194 cases显示文摘BACKGROUND: With the wide use of B-ultrasonography in recent years, the polypoid lesion of the gallbladde ( PLG) has been one of the most common diseases detected in biliary surgery. This study was to investigate the diag nostic method and operative indications of PLG. METHODS: The clinical and pathological data of 194 pa tients with PLG who had received operation at our hospita from January 1994 to September 2002 were analyzed retro spectively. Categorized data were analyzed by the chi square test. RESULTS: All the patients received preoperative B-ultra- sonography. 185 of the 194 PLG patients were diagnosed as having cholecystic polyp, and 9 adenomas. Among the 42 patients who received CT, 6 showed early gallbladder can cer. Pathologically, cholesterol polyps were mostly multi ple lesions (64.7%) with a mean diameter of3.86±2.2 mm in 136 patients. Of 16 patients with adenomas, 10 had a tumor diameter of more than 10 mm (62.5%). In 11 pa tients with gallbladder carcinoma, 7 were accompanied with gallbladder stone (63.6%). In addition, inflammatory polyps and adenomyomas were found in 25 and 6 patients respectively. CONCLUSIONS: B-ultrasonography is the most effective diagnostic method for detecting PLG. When large or irreg- ular lesions are found, CT should be performed in order to avoid missing of gallbladder carcinoma. Operative indica- tions for PLG include; a maximal tumor diameter of more than 10 mm; an over 50-year-old patient with a wide-base and a single polyp lesion; a wide-base lesion or a lesion showing a tendency to enlargement; co-existing gallbladder stone or cholecystitis; a patient without other diseases but obvious clinical features and failure of general ma- nagement ; big or long pedicels or polyps at the neck of the gallbladder for preventing the empty of the gallbladder and a history of biliary colic; and PLG with irregularly thick- ened local gallbladder wall.Xue-Jun Sun, Jing-Sen Shi, Yue Han, Jian-Sheng Wang and Hong Ren Xi’ an, China Department of Surgery, First Hospital of Xi’ an Jiao- tong University, Xi’ an 710061 , China 2004Hepatobiliary & Pancreatic Diseases International2004,3,4:24

10Ferroptosis is essential for diabetic cardiomyopathy and is prevented by sulforaphane via AMPK/NRF2 pathways显示文摘Herein,we define the role of ferroptosis in the pathogenesis of diabetic cardiomyopathy(DCM)by examining the expression of key regulators of ferroptosis in mice with DCM and a new ex vivo DCM model.Advanced glycation end-products(AGEs),an important pathogenic factor of DCM,were found to induce ferroptosis in engineered cardiac tissues(ECTs),as reflected through increased levels of Ptgs2 and lipid peroxides and decreased ferritin and SLC7 A11 levels.Typical morphological changes of ferroptosis in cardiomyocytes were observed using transmission electron microscopy.Inhibition of ferroptosis with ferrostatin-1 and deferoxamine prevented AGE-induced ECT remodeling and dysfunction.Ferroptosis was also evidenced in the heart of type 2 diabetic mice with DCM.Inhibition of ferroptosis by liproxstatin-1 prevented the development of diastolic dysfunction at 3 months after the onset of diabetes.Nuclear factor erythroid 2-related factor 2(NRF2)activated by sulforaphane inhibited cardiac cell ferroptosis in both AGE-treated ECTs and hearts of DCM mice by upregulating ferritin and SLC7 A11 levels.The protective effect of sulforaphane on ferroptosis was AMP-activated protein kinase(AMPK)-dependent.These findings suggest that ferroptosis plays an essential role in the pathogenesis of DCM;sulforaphane prevents ferroptosis and associated pathogenesis via AMPK-mediated NRF2 activation.This suggests a feasible therapeutic approach with sulforaphane to clinically prevent ferroptosis and DCM.Xiang Wang Xinxin Chen Wenqian Zhou Hongbo Men Terigen Bao Yike Sun Quanwei Wang Yi Tan Bradley B.Keller Qian Tong Yang Zheng Lu Cai 2022Acta Pharmaceutica Sinica B2022,12,2:20

12Effects of dietary supplementation of Artemisia argyi aqueous extract on antioxidant indexes of small intestine in broilers显示文摘The present study was conducted to investigate the effect of Artemisia argyi aqueous extract(AAE) on antioxidant indexes in the small intestine. A total of 192 Arbor Acre broiler chickens(one-day-old) were randomly divided into 4 treatments with 6 replicates of 8 chickens. These 4 diets were formulated by adding 0, 500,1,000 and 2,000 mg/kg AAE to the basal diet. The results showed as follows: 1) compared with the control, the total antioxidant capacity(T-AOC) in ileum for the 2,000 mg/kg treatment group was significantly increased at 21 days of age(P < 0.05); the T-AOC levels in jejunum and ileum were significantly increased in broilers supplemented with 500 mg/kg AAE at 42 days of age(P < 0.05), and the T-AOC levels in jejunum and ileum were significantly improved in 1,000 mg/kg treatment group(P < 0.01), 2) At 21 days of age, supplementation of 500 mg/kg AAE significantly increased the catalase(CAT) activity of small intestine, and the glutathione peroxidase(GSH-Px) activity of jejunum was improved(P < 0.01), meanwhile, the GSH-Px activity of duodenum and the total superoxide dismutase(T-SOD) activity of duodenum and jejunum were significantly higher than those of the control group(P < 0.05); supplementation of 1,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum and the GSH-Px activity of duodenum and jejunum(P < 0.05), and the ileum GSH-Px activity was significantly increased(P < 0.01); supplementation of 2,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum(P < 0.05). At 42 days of age, supplementation of 500 mg/kg AAE significantly increased the GSH-Px activity of ileum and the T-SOD activity of duodenum(P < 0.05),meanwhile, the T-SOD activity of jejunum was significantly increased(P < 0.01); supplementation of1,000 mg/kg AAE significantly increased the CAT activity of jejunum and the T-SOD activity of ileum(P < 0.01), and the GSH-Px activity of jejunum was significantly increased(P < 0.05); supplementation of2,000 mg/kg AAE significantly increased the T-SOD activity of ileum(P < 0.05), but significantly decreased the CAT activity of ileum and the GSH-Px activity of jejunum(P < 0.05). 3) The malondialdehyde(MDA) levels of 3 AAE supplementation groups were significantly decreased at 21 and 42 days of age(P < 0.05). The results suggested that dietary supplementation with AAE could improve the antioxidative capacity of small intestine in broilers.Fei Zhao Binlin Shi Dengsheng Sun Hongyan Chen Manman Tong Pengfei Zhang Xiaoyu Guo Sumei Yan 2016Animal Nutrition2016,,3:18

15Vision,application scenarios,and key technology trends for 6G mobile communications显示文摘With the global commercialization of the fifth-generation(5G)network,many countries,including China,USA,European countries,Japan,and Korea,have started exploring 6G mobile communication network,following the tradition of“planning the next while commercializing one generation”.Currently,studies on 6G networks are at the infancy stage.Research on the vision and requirements for 6G is still ongoing,and the industry is yet to clarify the key enabling technologies for 6G.However,6G will certainly build on the success of 5G.Therefore,developing high-quality 5G networks and seamlessly integrating 5G with verticals are the priorities before 2030,when 6G is projected to be commercialized.Also,global 5G standards will keep evolving to better support vertical applications.As a milestone,the Third-Generation Partnership Project(3GPP)published Release 16 in July 2020,which continuously enhanced the capabilities of mobile broadband service based on Release 15 and realized the support for low-delay and high-reliability applications,such as Internet of Vehicles and industrial Internet.Currently,3GPP is working on Releases 17 and 18,focusing on meeting the demands of medium-and high-data-rate machine communication with low-cost and high-precision positioning,which will be published in June 2022.Thus,6G networks will further expand the application fields and scope of the Internet of Things to accommodate those services and applications that are beyond the capabilities of 5G networks.Herein,we present our vision,application scenarios,and key technological trends for 6G networks.Furthermore,we propose several future research opportunities in 6G networks with regard to industrialization and standardization.Zhiqin WANG Ying DU Kejun WEI Kaifeng HAN Xiaoyan XU Guiming WEI Wen TONG Peiying ZHU Jianglei MA Jun WANG Guangjian WANG Xueqiang YAN Jiying XIANG He HUANG Ruyue LI Xinhui WANG Yingmin WANG Shaohui SUN Shiqiang SUO Qiubin GAO Xin SU 2022Science China(Information Sciences)2022,65,5:17
16A detailed Lower Triassic conodont biostratigraphy and its implications for the GSSP candidate of the Induan-Olenekian boundary in Chaohu, Anhui Province显示文摘Chaohu is located in a deep part of carbonate ramp on the Lower Yangtze Block,which belonged to the low-latitude eastern Tethyan archipelago during the Early Triassic.Fossils were very rich in the Lower Triassic of Chaohu.Bivalves,ammonoids,conodonts were very common throughout the Lower Triassic,while fish fossils were generally rich in some beds of the upper part.It is one of the most typical sections for the Early Triassic chronostratigraphy in the world.Although various fossils had been studied in the 1980s and 1990s,recent studies based upon new and more detailed collections from the Lower Triassic of Chaohu showed that the conodont zonation needs revision.We collected Lower Triassic conodont fossils from continuous sections of the West Pingdingshan,North Pingdingshan and South Majiashan,Chaohu,Anhui Province,and updated zonations were made for each section.Eight conodont zones have been dis- tinguished.They are,in ascending order,Hindeodus typicalis zone,Neogondolella krystyni zone,Neospathodus kummeli zone,Neospath- odus dieneri zone,Neospathodus waageni zone,Neospathodus pingdingshanensis zone,Neospathodus homeri zone,and Neospathodus anhuinensis zone.The first occurrence of Neospathodus waageni eowaageni of the N.w.eowaageni subzone(i.e.the base of the N.waageni zone)is suggested as the marker to define the Induan–Olenekian boundary.Laishi Zhao Jinnan Tong Zhiming Sun Michael J.

17DISLOCATION DISSOCIATIONS AND FAULTENERGIES IN Ni_3Al ALLOYS DOPED WITH PALLADIUM显示文摘Dislocation structures in polycrystalline Ni 3Al alloy doped with palladium deformed at room temperature have been investigated by transmission electron microscopy. The structure consists mainly of dislocations dissociated into a /2〈011〉 super partials bounding an anti phase boundary (APB). Dislocations dissociated into a /3〈112〉 super Shockley partials bounding a superlattice intrinsic stacking fault (SISF) are also common debris. The majority of the SISFs are truncated loops, i.e. the partials bounding the SISF are of similar Burgers vector. These faulted loops are generated from APB coupled dislocations, according to a mechanism for formation of SISFs proposed by Suzuki et al , and recently modified by Chiba et al . The APB energies for {111} and {010} slip planes are measured to be 144±20 mJ/m 2 and 102±11 mJ/m 2 respectively, and the SISF energy has been estimated to be 12 mJ/m 2 in this alloy. It is concluded that the dislocation structure in Ni 74.5 Pd 2Al 23.5 alloy deformed at room temperature is similar to that in binary Ni 3Al, and the difference in fault energies between these two alloys is small. Thus, it seems unlikely that the enhancement of ductility of Ni 74.5 Pd 2Al 23.5 results from only such a small decrease of the ordering energy of the alloy. SISF bounding dislocations also have no apparent influence on the ductilization of Ni 74.5 Pd 2Al 23.5 alloy.J. Sun *# , C. S. Lee # and J. K. L.

18Prognosis-related classifi cation and dynamic monitoring of immune status in patients with sepsis:A prospective observational study显示文摘BACKGROUND:The dynamic monitoring of immune status is crucial to the precise and individualized treatment of sepsis.In this study,we aim to introduce a model to describe and monitor the immune status of sepsis and to explore its prognostic value.METHODS:A prospective observational study was carried out in Zhongshan Hospital,Fudan University,enrolling septic patients admitted between July 2016 and December 2018.Blood samples were collected at days 1 and 3.Serum cytokine levels(e.g.,tumor necrosis factor-α[TNF-α],interleukin-10[IL-10])and CD14+monocyte human leukocyte antigen-D-related(HLA-DR)expression were measured to serve as immune markers.Classifi cation of each immune status,namely systemic inflammatory response syndrome(SIRS),compensatory anti-inflammatory response syndrome(CARS),and mixed antagonistic response syndrome(MARS),was defined based on levels of immune markers.Changes of immune status were classifi ed into four groups which were stabilization(SB),deterioration(DT),remission(RM),and non-remission(NR).RESULTS:A total of 174 septic patients were enrolled including 50 non-survivors.Multivariate analysis discovered that IL-10 and HLA-DR expression levels at day 3 were independent prognostic factors.Patients with MARS had the highest mortality rate.Immune status of 46.1%patients changed from day 1 to day 3.Among four groups of immune status changes,DT had the highest mortality rate,followed by NR,RM,and SB with mortality rates of 64.7%,42.9%,and 11.2%,respectively.CONCLUSIONS:Severe immune disorder defi ned as MARS or deterioration of immune status defi ned as DT lead to the worst outcomes.The preliminary model of the classifi cation and dynamic monitoring of immune status based on immune markers has prognostic values and is worthy of further investigation.Jun Yin Yao Chen Jun-ling Huang Lei Yan Zhong-shu Kuang Ming-ming Xue Si Sun Hao Xiang Yan-yan Hu Zhi-min Dong Chao-yang Tong Chun-xue Bai Zhen-ju Song 2021World Journal of Emergency Medicine2021,12,3:16
19The Chromosome-Based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis显示文摘The rubber tree,Hevea brasiliensis,produces natural rubber that serves as an essential industrial raw material.Here,we present a high-quality reference genome for a rubber tree cultivar GT1 using single-molecule real-time sequencing(SMRT)and Hi-C technologies to anchor the~1.47-Gb genome assembly into 18 pseudochromosomes.The chromosome-based genome analysis enabled us to establish a model of spurge chromosome evolution,since the common paleopolyploid event occurred before the split of Hevea and Manihot.We show recent and rapid bursts of the three Hevea-specific LTR-retrotransposon families during the last 10 million years,leading to the massive expansion by~65.88%(~970 Mbp)of the whole rubber tree genome since the divergence from Manihot.We identify large-scale expansion of genes associated with whole rubber biosynthesis processes,such as basal metabolic processes,ethylene biosynthesis,and the activation of polysaccharide and glycoprotein lectin,which are important properties for latex production.A map of genomic variation between the cultivated and wild rubber trees was obtained,which contains~15.7 million high-quality single-nucleotide polymorphisms.We identified hundreds of candidate domestication genes with drastically lowered genomic diversity in the cultivated but not wild rubber trees despite a relatively short domestication history of rubber tree,some of which are involved in rubber biosynthesis.This genome assembly represents key resources for future rubber tree research and breeding,providing novel targets for improving plant biotic and abiotic tolerance and rubber production.Jin Liu Cong Shi Cheng-Cheng Shi Wei Li Qun-Jie Zhang Yun Zhang Kui Li Hui-Fang Lu Chao Shi Si-Tao Zhu Zai-Yun Xiao Hong Nan Yao Yue Xun-Ge Zhu Yu Wu Xiao-Ning Hong Guang-Yi Fan Yan Tong Dan Zhang Chang-Li Mao Yun-Long Liu Shi-Jie Hao Wei-Qing Liu Mei-Qi Lv Hai-Bin Zhang Yuan Liu Ge-Ran Hu-tang Jin-Peng Wang Jia-Hao Wang Ying-Huai Sun Shu-Bang Ni Wen-Bin Chen Xing-Cai Zhang Yuan-Nian Jiao Evan E.Eichler Guo-Hua Li Xin Liu Li-Zhi Gao 2020Molecular Plant2020,13,2:15
20Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development.Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding 2020Science China Chemistry2020,63,6:15
