3Special Section:SARS-CoV-2 Preliminary evidence from a multicenter prospective observational study of the safety and efficacy of chloroquine for the treatment of COVID-19显示文摘Effective therapies are urgently needed for the SARS-CoV-2 pandemic.Chloroquine has been proved to have antiviral effect against coronavirus in vitro.In this study,we aimed to assess the efficacy and safety of chloroquine with different doses in COVID-19.In this multicenter prospective observational study,we enrolled patients older than 18 years old with confirmed SARS-CoV-2 infection excluding critical cases from 12 hospitals in Guangdong and Hubei Provinces.Eligible patients received chloroquinephosphate s00 mg,orally,once(half dose)or twice(full dose)daily.Patients treated with non-chloroquine therapy were included as historical controls.The primary endpoint is the time to undetectable viral RNA.Secondary outcomes include the proportion of patients with undetectable viral RNA by day 10 and 14,hospitalization time,duration of fever,and adverse events.A total of 197 patients completed chloroquine treatment,and 176patients were included as historical controls.The median time to achieve an undetectable viral RNA was shorter in chloroquine than in non-chloroquine(absolute difference in medians-6.0 days;95%CI-6.0 to—4.0).The duration of fever is shorter in chloroquine(geometric mean ratio 0.6;95%CIO.5 to 0.8).No serious adverse events were observed in the chloroquine group.Patients treated with half dose experienced lower rate of adverse events than with full dose.Although randomized trials are needed for further evaluation,this study provides evidence for safety and efficacy of chloroquine in COVID-19 and suggests that chloroquine can be a cost-effective therapy for combating the COVID-19 pandemic.Mingxing Huang Man Li Fei Xiao Pengfei Pang Jiabi Liang Tiantian Tang Shaoxuan Liu Binghui Chen Jingxian Shu Yingying You Yang Li Meiwen Tang Jianhui Zhou Guanmin Jiang Jingfen Xiang Wenxin Hong Songmei He Zhaoqin Wang Jianhua Feng Changqing Lin Yinong Ye Zhilong Wu Yaocai Li Bei Zhong Ruilin Sun Zhongsi Hong Jing Liu Huili Chen Xiaohua Wang Zhonghe Li Duanqing Pei Lin Tian Jinyu Xia Shanping Jiang Nanshan Zhong Hong Shan 2020National Science Review2020,7,9:20
4Differential study of DCE-MRI parameters in spinal metastatic tumors, brucellar spondylitis and spinal tuberculosis显示文摘Objective: In the present study, spinal metastatic tumors, brucellar spondylitis and spinal tuberculosis were quantitatively analyzed using dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI) to assess the value of DCE-MRI in the differential diagnosis of these diseases.Methods: Patients with brucellar spondylitis, spinal tuberculosis or a spinal metastatic tumor(30 cases of each)received conventional MRI and DCE-MRI examination. The volume transfer constant(K^(trans)), rate constant(K_(ep)),extravascular extracellular volume fraction(V_e) and plasma volume fraction(V_p) of the diseased vertebral bodies were measured on the perfusion parameter map, and the differences in these parameters between the patients were compared.Results: For pathological vertebrae in cases of spinal metastatic tumor, brucellar spondylitis and spinal tuberculosis, respectively, the K^(trans) values(median ± quartile pitch) were 0.989±0.014, 0.720±0.011 and0.317±0.005 min^(–1); the K_(ep) values were 2.898±0.055, 1.327±0.017 and 0.748±0.006 min^(–1); the V_e values were 0.339±0.008, 0.542±0.013 and 0.428±0.018; the V_p values were 0.048±0.008, 0.035±0.004 and 0.028±0.009; the corresponding H values were 50.25(for K_(trans)), 52.47(for K_(ep)), 48.33(for V_e) and 46.56(for V_p), and all differences were statistically significant(two-sided P<0.05).Conclusions: The quantitative analysis of DCE-MRI has a certain value in the differential diagnosis of spinal metastatic tumor, brucellar spondylitis and spinal tuberculosis.Pengfei Qiao Pengfei Zhao Yang Gao Yuzhen Bai Guangming Niu 2018Chinese Journal of Cancer Research2018,30,4:16
5Unequal-thickness billet optimization in transitional region during isothermal local loading forming of Ti-alloy rib-web component using response surface method显示文摘Avoiding the folding defect and improving the die filling capability in the transitional region are desired in isothermal local loading forming of a large-scale Ti-alloy rib-web component(LTRC). To achieve a high-precision LTRC, the folding evolution and die filling process in the transitional region were investigated by 3 D finite element simulation and experiment using an equal-thickness billet(ETB). It is found that the initial volume distribution in the second-loading region can greatly affect the amount of material transferred into the first-loading region during the second-loading step, and thus lead to the folding defect. Besides, an improper initial volume distribution results in non-concurrent die filling in the cavities of ribs after the second-loading step, and then causes die underfilling. To this end, an unequal-thickness billet(UTB) was employed with the initial volume distribution optimized by the response surface method(RSM). For a certain eigenstructure, the critical value of the percentage of transferred material determined by the ETB was taken as a constraint condition for avoiding the folding defect in the UTB optimization process,and the die underfilling rate was considered as the optimization objective. Then, based on the RSM models of the percentage of transferred material and the die underfilling rate, non-folding parameter combinations and optimum die filling were achieved. Lastly, an optimized UTB was obtained and verified by the simulation and experiment.Ke WEI Mei ZHAN Xiaoguang FAN He YANG Pengfei GAO Miao MENG 2018Chinese Journal of Aeronautics2018,31,4:13
6Status and distribution changes of the endangered Green Peafowl (Pavo muticus) in China over the past three decades (1990s-2017)显示文摘Background: Understanding the changes in population dynamics, including demographics, distribution and threats, is essential for species status assessing. The endangered Green Peafowl(Pavo muticus) has experienced sharp population declines and distribution range diminishing both in China and Southeast Asia. Field population surveys have not been conducted in China since the 1990 s, which hindered conservation planning and decision-making.Methods: With interview and line transects methods, we figured out the population and distribution changes of Green Peafowl across its historical ranges over the past three decades in China during 2014-2017.Results: The Green Peafowl once habituated in 54 counties in China. Nearly 60% of the distribution counties were lost in the past three decades, with the left 22 counties distributed in central, southern and western Yunnan, SW China. Population decrease detected in all distribution areas except for Shuangbai and Xinping county where more than 60% of the total population is located. Only about 30% of the former bird population were recorded with the same interviewing method as 20 years ago. Three birds, 1 carcass, 6 calls and 12 footprints were detected along the 865 km line transects, indic-ating extremely low encounter rate of Green Peafowl in field. Sharp decreases in flock sizes were also detected, from 820 birds per flock in the 1990 s to 3-5 birds at present. Poaching and habitat conversion are two widespread and long-lasting threats, while poisoning caused mortality in the past and hydropower construction affect regional population's survival. Large flocks of 18–27 birds were discovered in the field, which increases our confidence of population recovery of this endangered pheasant in China.Conclusions: Only interviewed bird number and counts based on line transects were presented in this study, without further population estimation due to limitation of the data sets. Although the actual population of this cryptic bird must be underestimated, dramatic population declines and distribution concentrations of the endangered Green Peafowl occurred over the past 30 years in China undoubtedly.Dejun Kong Fei Wu Pengfei Shan Jianyun Gao Dao Yan Weixiong Luo Xiaojun Yang 2018Avian Research2018,9,2:12
7Targeting cancer stem cell pathways for cancer therapy显示文摘Since cancer stem cells(CSCs)were first identified in leukemia in 1994,they have been considered promising therapeutic targets for cancer therapy.These cells have self-renewal capacity and differentiation potential and contribute to multiple tumor malignancies,such as recurrence,metastasis,heterogeneity,multidrug resistance,and radiation resistance.The biological activities of CSCs are regulated by several pluripotent transcription factors,such as OCT4,Sox2,Nanog,KLF4,and MYC.In addition,many intracellular signaling pathways,such as Wnt,NF-κB(nuclear factor-κB),Notch,Hedgehog,JAK-STAT(Janus kinase/signal transducers and activators of transcription),PI3K/AKT/mTOR(phosphoinositide 3-kinase/AKT/mammalian target of rapamycin),TGF(transforming growth factor)/SMAD,and PPAR(peroxisome proliferator-activated receptor),as well as extracellular factors,such as vascular niches,hypoxia,tumor-associated macrophages,cancer-associated fibroblasts,cancer-associated mesenchymal stem cells,extracellular matrix,and exosomes,have been shown to be very important regulators of CSCs.Molecules,vaccines,antibodies,and CAR-T(chimeric antigen receptor T cell)cells have been developed to specifically target CSCs,and some of these factors are already undergoing clinical trials.This review summarizes the characterization and identification of CSCs,depicts major factors and pathways that regulate CSC development,and discusses potential targeted therapy for CSCs.Liqun Yang Pengfei Shi Gaichao Zhao Jie Xu Wen Peng Jiayi Zhang Guanghui Zhang Xiaowen Wang Zhen Dong Fei Chen Hongjuan Cui 2020Signal Transduction and Targeted Therapy2020,5,1:12
8Exosomes derived from human amniotic epithelial cells accelerate diabetic wound healing via PI3K-AKT-mTOR-mediated promotion in angiogenesis and fibroblast function显示文摘Background:Diabetic wounds are one of the most common and serious complications of diabetes mellitus,characterized by the dysfunction of wound-healing-related cells in quantity and quality.Our previous studies revealed that human amniotic epithelial cells(hAECs)could promote diabetic wound healing by paracrine action.Interestingly,numerous studies demonstrated that exosomes derived from stem cells are the critical paracrine vehicles for stem cell therapy.However,whether exosomes derived from hAECs(hAECs-Exos)mediate the effects of hAECs on diabetic wound healing remains unclear.This study aimed to investigate the biological effects of hAECs-Exos on diabetic wound healing and preliminarily elucidate the underlying mechanism.Methods:hAECs-Exos were isolated by ultracentrifugation and identified by transmission electron microscopy,dynamic light scattering and flow cytometry.A series of in vitro functional analyses were performed to assess the regulatory effects of hAECs-Exos on human fibroblasts(HFBs)and human umbilical vein endothelial cells(HUVECs)in a high-glycemic microenvironment.Highthroughput sequencing and bioinformatics analyses were conducted to speculate the related mechanisms of actions of hAECs-Exos on HFBs and HUVECs.Subsequently,the role of the candidate signaling pathway of hAECs-Exos in regulating the function of HUVECs and HFBs,as well as in diabetic wound healing,was assessed.Results:hAECs-Exos presented a cup-or sphere-shaped morphology with a mean diameter of 105.89±10.36 nm,were positive for CD63 and TSG101 and could be internalized by HFBs and HUVECs.After that,hAECs-Exos not only significantly promoted the proliferation and migration of HFBs,but also facilitated the angiogenic activity of HUVECs in vitro.High-throughput sequencing revealed enriched miRNAs of hAECs-Exos involved in wound healing.Kyoto Encyclopedia of Genes and Genomes and Gene Ontology analyses have shown that the target genes of the top 15 miRNAs were highly enriched in the PI3K-AKT pathway.Further functional studies demonstrated that the PI3K-AKT-mTOR pathway was necessary for the induced biological effects of hAECs-Exos on HFBs and HUVECs,as well as on wound healing,in diabetic mice.Conclusions:Our findings demonstrated that hAECs-Exos represent a promising,novel strategy for diabetic wound healing by promoting angiogenesis and fibroblast function via activation of the PI3K-AKT-mTOR pathway.Pei Wei Chenjian Zhong Xiaolan Yang Futing Shu Shichu Xiao Teng Gong Pengfei Luo Li Li Zhaohong Chen Yongjun Zheng Zhaofan Xia 2020Burns & Trauma2020,8,1:12

12Design and implementation of rigid-flexible coupling for a half-flexible single jack nozzle显示文摘The aerodynamic design of a rigid-flexible coupling profile is the decisive factor for the flow-field quality of a supersonic free jet wind tunnel nozzle, and its mechanic dynamic features are the key for engineering implementation of continuous Mach number regulations. To fulfill the requirements of a free jet inlet/engine compatibility test within a wide simulation envelop, both uniform flow-fields of continuous acceleration and deceleration are necessary. In this paper, the aerodynamic design methods of an expansion wall and machinery implementation plan for the halfflexible single jack nozzle were researched. The profile control in nozzle flexible plate design was studied with a rigid-flexible coupling method. Design and calculations were performed with the help of numerical simulation. The technique of axial free stretching of the flexible plate was used to improve the matching performance between the designed elasticity profile and the theoretical one, and the rigid-flexible coupling structure was calibrated by wind tunnel tests. Results indicate that the flexible plate aerodynamic design method used here is effective and feasible. Via rigidflexible coupling design, the flexible plate agrees with the rigid body very well, and continuous Mach number changes can be achieved during the tests. The nozzle's exit flow-field uniformity meets the requirements of China Military Standard(GJB).Chen Pengfei Wu Feng Xu Jinglei Feng Xudong Yang Qiao 2016Chinese Journal of Aeronautics2016,29,6:8
13The apparent contact angle of water droplet on the micro-structured hydrophobic surface显示文摘The apparent contact angle of Cassie-Baxter state water droplets can be calculated by the existing theoretical formula, but due to the defects of the micro-structured hydrophobic surface and some inevitable tiny disturbances in the experiment, Cassie-Baxter state water droplets will appear partly in Wenzel state, that is, the mixed state water droplets. In this paper, apparent contact angles of Cassie-Baxter state and mixed state water droplets on micro-structured hydrophobic surfaces are compared. The research shows that if the projected area fraction of water-solid F in the Cassie-Baxter formula is replaced by the local projected area fraction of water-solid F′, the apparent contact angles of water droplets in both Cassie-Baxter state and the mixed state can be calculated. Further experimental results indicate that the contact state of water droplets nearby the outermost three-phase contact line plays a more important role in determining the apparent contact angle. This conclusion is significant to the understanding of the apparent contact angle and wetting property.YANG ChangWei, HE Feng & HAO PengFei School of Aerospace, Tsinghua University, Beijing 100084, China 2010Science China Chemistry2010,53,4:8
14Measurement of the fluidized velocity in gas-solid fluidized beds based on AE signal analysis by wavelet packet transform显示文摘An energy distribution theory was presented based on regular evolvement of energy fraction of acous-tic signals with fluidization velocity. Wavelet packet analysis was used in processing the acoustic sig-nals originated from particle impact on the wall of a fluidized bed. A new criterion of judging incipient fluidization(Umf) velocity and minimum turbulent velocity(Umt) was proposed according to the energy distribution theory. Experiments were performed with five groups of high density polyethylene(PE) particles and one bimodal PE to acquire incipient fluidization velocity and minimum turbulent velocity by using the criterion. The feasibility of this method in obtaining characteristic fluidization parameters was further verified by comparing it to results from the pressure drop method and the empirical value from industry.WANG JingDai YANG YongRong GE PengFei SHU WeiJie HOU LinXi 2007Science China Chemistry2007,50,2:8
