12018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
2Deformability characteristics of jointed rock masses under uniaxial compression显示文摘We investigated the combined influence of joint inclination angle and joint continuity factor on deformation behavior of jointed rock mass for gypsum specimens with a set of non-persistent open flaws in uniaxial compression.Complete axial stress-strain curves were classified into four types,i.e.,single peak,softening after multi-peak yield platform,hardening after multi-peak yield platform and multi-peak during softening.Observation of crack evolution on the specimen surface reveals that the deformation behavior is correlated to the closure of pre-existing joint,development of fractures in rock matrix and teeth shearing of the shear plane.To investigate the brittleness of the specimens,the ratio of the residual strength to the maximum peak strength as well as the first and last peak strains were studied.At the same joint inclination angle,the ratios between residual strength and the maximum peak strength and the last peak strains increased while the first peak strain decreased with the increase of joint continuity factor.At the same joint continuity factor,the curves of the three brittleness parameters vs.joint inclination angle can either be concave or convex single-peak or wave-shaped.Chen Xin Liao Zhihong Peng Xi 2012International Journal of Mining Science and Technology2012,22,2:44
3Distribution of the COVID-19 epidemic and correlation with population emigration from Wuhan,China显示文摘Background:The ongoing new coronavirus pneumonia(Corona Virus Disease 2019,COVID-19)outbreak is spreading in China,but it has not yet reached its peak.Five million people emigrated from Wuhan before lockdown,potentially representing a source of virus infection.Determining case distribution and its correlation with population emigration from Wuhan in the early stage of the epidemic is of great importance for early warning and for the prevention of future outbreaks.Methods:The official case report on the COVID-19 epidemic was collected as of January 30,2020.Time and location information on COVID-19 cases was extracted and analyzed using ArcGIS and WinBUGS software.Data on population migration from Wuhan city and Hubei province were extracted from Baidu Qianxi,and their correlation with the number of cases was analyzed.Results:The COVID-19 confirmed and death cases in Hubei province accounted for 59.91%(5806/9692)and 95.77%(204/213)of the total cases in China,respectively.Hot spot provinces included Sichuan and Yunnan,which are adjacent to Hubei.The time risk of Hubei province on the following day was 1.960 times that on the previous day.The number of cases in some cities was relatively low,but the time risk appeared to be continuously rising.The correlation coefficient between the provincial number of cases and emigration from Wuhan was up to 0.943.The lockdown of 17 cities in Hubei province and the implementation of nationwide control measures efficiently prevented an exponential growth in the number of cases.Conclusions:The population that emigrated from Wuhan was the main infection source in other cities and provinces.Some cities with a low number of cases showed a rapid increase in case load.Owing to the upcoming Spring Festival return wave,understanding the risk trends in different regions is crucial to ensure preparedness at both the individual and organization levels and to prevent new outbreaks.Ze-Liang Chen Qi Zhang Yi Lu Zhong-Min Guo Xi Zhang Wen-Jun Zhang Cheng Guo Cong-Hui Liao Qian-Lin Li Xiao-Hu Han Jia-Hai Lu 2020Chinese Medical Journal2020,,9:15

5Matrine suppresses lipopolysaccharide-induced fibrosis in human peritoneal mesothelial cells by inhibiting the epithelial-mesenchymal transition显示文摘Background: Peritoneal fibrosis is the primary reason that patients with end-stage renal disease (ESRD) have to cease peritoneal dialysis. Peritonitis caused by Gram-negative bacteria such as Escherichia coli (E. coli) were on the rise. We had previously shown that matrine inhibited the formation of biofilm by E. coli. However, the role of matrine on the epithelial-mesenchymal transition (EMT) in peritoneal mesothelial cells under chronic inflammatory conditions is still unknown. Methods: We cultured human peritoneal mesothelial cells (HPMCs) with lipopolysaccharide (LPS) to induce an environment that mimicked peritonitis and investigated whether matrine could inhibit LPS-induced EMT in these cells. In addition, we investigated the change in expression levels of the miR-29b and miR-129-5p. Results: We found that 10 jjig/ml of LPS induced EMT in HPMCs. Matrine inhibited LPS-induced EMT in HPMCs in a dose-dependent manner. We observed that treatment with matrine increased the expression of E-cadherin (F= 50.993, P< 0.01), and decreased the expression of alpha-smooth muscle actin (F= 32.913, P < 0.01). Furthermore, we found that LPS reduced the expression levels of miR- 29b and miR-129-5P in HPMCs, while matrine promoted the expression levels of miR-29b and miR-129-5P. Conclusions: Matrine could inhibit LPS-induced EMT in HPMCs and reverse LPS inhibited expressions of miR-29 b and miR-129- 5P in HPMCs, ultimately reduce peritoneal fibrosis. These findings provide a potential theoretical basis for using matrine in the prevention and treatment of peritoneal fibrosis.Yi-Zheng Li Xi Peng Yun-Hua Ma Fu-Ji Li Yun-Hua Liao 2019Chinese Medical Journal2019,,6:10
6FAST RECURSIVE LEAST SQUARES LEARNING ALGORITHM FOR PRINCIPAL COMPONENT ANALYSIS显示文摘Based on the least-square minimization a computationally efficient learning algorithm for the Principal Component Analysis(PCA) is derived. The dual learning rate parameters are adaptively introduced to make the proposed algorithm providing the capability of the fast convergence and high accuracy for extracting all the principal components. It is shown that all the information needed for PCA can be completely represented by the unnormalized weight vector which is updated based only on the corresponding neuron input-output product. The convergence performance of the proposed algorithm is briefly analyzed.The relation between Oja’s rule and the least squares learning rule is also established. Finally, a simulation example is given to illustrate the effectiveness of this algorithm for PCA.Ouyang Shan Bao Zheng Liao Guisheng(Guilin Institute of Electronic Technology, Guilin 541004)(Key Laboratory of Radar Signal Processing, Xidian Univ., Xi’an 710071) 2000Journal of Electronics(China)2000,17,3:8
7A 60-year sedimentary record of natural and anthropogenic impacts on Lake Chenghai,China显示文摘Recent sediments from Lake Chenghai,China,were investigated at high temporal resolution to trace both natural and anthropogenic effects on the lake using total organic carbon(TOC),total nitrogen(TN),total phosphorus(TP),organic phosphorus(P o),inorganic phosphorus(P i) and organic carbon and nitrogen stable isotopes(δ 13 C org and δ 15 N) in a 137 Cs-dated sediment core.The results indicated that the sedimentary record covers the last 60 years,during which the lake had undergone apparent changes in nutrient sources and productivity in response to nutrient loading.Prior to the late 1980s,the nutrient contents in sediments mainly originated from algae and lake productivity was relatively stable.Since the late 1980s,increasing TOC,TN and TP concentrations together with the change of δ 13 C org and δ 15 N suggested anthropogenic perturbations in nutrient loading and lake productivity.Endogenic nutrients derived from algae and anthropogenic inputs were two important sources of sedimentary nutrients.The anthropogenic nutrients mainly originated from the discharge of industrial wastewater and artificial cultivation of Spirulina after the middle 1980s,and domestic wastewater discharged from Yongsheng County since 1993.Fengyu Zan Shouliang Huo Beidou Xi Jingtian Zhang Haiqing Liao Yue Wang Kevin M.Yeager 2012Journal of Environmental Sciences2012,24,4:8

9Sox9 augments BMP2-induced chondrogenic differentiation by downregulating Smad7 in mesenchymal stem cells(MSCs)显示文摘Cartilage injuries caused by arthritis or trauma pose formidable challenges for effective clinical management due to the limited intrinsic proliferative capability of chondrocytes.Autologous stem cell-based therapies and transgene-enhanced cartilage tissue engineering may open new avenues for the treatment of cartilage injuries.Bone morphogenetic protein 2(BMP2)induces effective chondrogenesis of mesenchymal stem cells(MSCs)and can thus be explored as a potential therapeutic agent for cartilage defect repair.However,BMP2 also induces robust endochondral ossification.Although the precise mechanisms through which BMP2 governs the divergence of chondrogenesis and osteogenesis remain to be fully understood,blocking endochondral ossification during BMP2-induced cartilage formation may have practical significance for cartilage tissue engineering.Here,we investigate the role of Sox9-donwregulated Smad7 in BMP2-induced chondrogenic differentiation of MSCs.We find that overexpression of Sox9 leads to a decrease in BMP2-induced Smad7 expression in MSCs.Sox9 inhibits BMP2-induced expression of osteopontin while enhancing the expression of chondrogenic marker Col2a1 in MSCs.Forced expression of Sox9 in MSCs promotes BMP2-induced chondrogenesis and suppresses BMP2-induced endochondral ossification.Constitutive Smad7 expression inhibits BMP2-induced chondrogenesis in stem cell implantation assay.Mouse limb explant assay reveals that Sox9 expands BMP2-stimulated chondrocyte proliferating zone while Smad7 promotes BMP2-intitated hypertrophic zone of the growth plate.Cell cycle analysis indicates that Smad7 induces significant early apoptosis in BMP2-stimulated MSCs.Taken together,our results strongly suggest that Sox9 may facilitate BMP2-induced chondrogenesis by downregulating Smad7,which can be exploited for effective cartilage tissue engineering.Chen Zhao Wei Jiang Nian Zhou Junyi Liao Mingming Yang Ning Hu Xi Liang Wei Xu Hong Chen Wei Liu Lewis L.Shi Leonardo Oliveira Jennifer Moriatis Wolf Sherwin Ho Aravind Athiviraham H.M.Tsai Tong-Chuan He Wei Huang 2017Genes & Diseases2017,4,4:7
10Microwave-assisted Polymerization of D,L-Lactide with Stannous Octanoate as Catalyst显示文摘Poly (lactic acid) (PLA) was synthesized by microwave-assisted ring-opening poly- merization of D, L-lactide with stannous octanoate (SnOct2) as catalyst. Its weight-average molar mass (Mw) ranged from 39000 to 67000 and the polydispersity index from 1.3 to 1.7. The polymerization rate was much faster than that of the conventional thermal polymerization. A degradation of newly formed PLA in reaction mixture by microwave irradiation was observed.Li Jian LIU* Chao ZHANG, Li Qiong LIAO, Xu Li WANG, Ren Xi ZHUO Department of Polymer Science, College of Chemistry and Molecular Science, Wuhan University The Research Laboratory of SEDC of Biomedical Polymer Materials at Wuhan University, Wuhan 430072 2001Chinese Chemical Letters2001,12,8:7

13Triassic Transgressive-Regressive Sequences in Guizhou-Guangxi Region, South China显示文摘Seven third-order transgressive-regressive sequences are recognized in the Early Triassic -Early Carnian stratigraghc succession of Guizhou-Guangxi region, South China. Based on currently available ages by the correlation of conodont ammonites and bivalve faunas, these sequences range approximately from 1.0 Ma to 5.6 Ma, with the average of 3 Ma. They occur largely in the Griesbachian-Dienerian, Smithian,uppermost Smithian-lowermost Anisian, Lower Anisian, Middle Anisian, Upper Anisian-Upper Ladinian and the uppermost Ladinian-Lower Carnian respectively, and can be grouped into three second-order transgressive-regressive supersequences. A relative sea level curve is established from the sequence stratigraghic analysis. Transgressive-regressive sequences,bounded by transgressive surfaces and the correlatable unconformities, are real unconformity-bounded units of lower rank. Each sequence comprises transgressive, highstand and regressive systems tracts, and can be easily correlated with the depositional sequence.Wei Jiayong (Regional Geological Survey, Xi’an College of Geology, Xi ’an 710054) Liao Nengmao Yu Youyi (Regional Geological Surveying Institute of Guizhou, Guiyang 550005) 1996Journal of Earth Science1996,15,1:6
14800 Gbit/s transmission over 1 km single-mode fiber using a four-channel silicon photonic transmitter显示文摘We demonstrate the optical transmission of an 800 Gbit/s(4×200 Gbit/s)pulse amplitude modulation-4(PAM-4)signal and a 480 Gbit/s(4×120 Gbit/s)on–off-keying(OOK)signal by using a high-bandwidth(BW)silicon photonic(SiP)transmitter with the aid of digital signal processing(DSP).In this transmitter,a four-channel SiP modulator chip is co-packaged with a four-channel driver chip,with a measured 3 dB BW of 40 GHz.DSP is applied in both the transmitter and receiver sides for pre-/post-compensation and bit error rate(BER)calculation.Back-to-back(B2B)BERs of the PAM-4 signal and OOK signal are first measured for each channel of the transmitter with respect to a variety of data rates.Similar BER performance of four channels shows good uniformity of the transmitter between different channels.The BER penalty of the PAM-4 and OOK signals for 500 m and 1 km standard single-mode fiber(SSMF)transmission is then experimentally tested by using one channel of the transmitter.For a 200 Gbit/s PAM-4 signal,the BER is below the hard-decision forward error correction(HD-FEC)threshold for B2B and below the soft-decision FEC(SD-FEC)threshold after 1 km transmission.For a 120 Gbit/s OOK signal,the BER is below SD-FEC threshold for B2B.After 500 m and 1 km transmission,the data rate of the OOK signal shrinks to 119 Gbit/s and 118 Gbit/s with the SD-FEC threshold,respectively.Finally,the 800 Gbit/s PAM-4 signal with 1 km transmission is achieved with the BER of all four channels below the SD-FEC threshold.Hongguang Zhang Miaofeng Li Yuguang Zhang Di Zhang Qiwen Liao Jian He Shenglei Hu Bo Zhang Lei Wang Xi Xiao Nan Qi Shaohua Yu 2020Photonics Research2020,8,11:5
15Post-marketing safety surveillance and reevaluation of Motherwort injection:A clinical study of 10094 cases显示文摘OBJECTIVE:To investigate the safety profiles of Motherwort injection(MI).METHODS:A multi-center,prospective and drugderived hospital intensive monitoring method was conducted to assess the safety of MI in real world applications.This study was based on a very large population after the injection was approved and marketed in China.All patients using the injection in participating hospitals were monitored to determine the incidence,pattern,severity and outcome of associated adverse events.RESULTS:The post-marketing surveillance was performed in 10 094 female patients from April to December,2015.The incidence of adverse drug reactions(ADRs) was 0.79‰(8/10 094).Among the 8 patients,the reported adverse events mainly included systemic abnormalities,such as fever,chills and eyelid edema;skin and appendages disorders,such as pruritus and rash;gastrointestinal disorders,such as nausea,abdominal distension and pain;heart rate and rhythm disorders,such as palpitation and increased heart rate.All of these ADRs were mild in severity.CONCLUSION:In this study the ADRs incidence rate of MI is very low,which supports that it is generally safe for use in obstetric and gynecological diseases.However,the total number of 8 ADRs recorded over a relatively short time span seems limited,and the low number of reports could not represent an absolute guarantee of safety.Cao Shan Zhang Wenhao Zhao Ziwei Heng Mingli Bu Huaien Wang Hongwu Liu Xinghui Wang Zhong Cai Yan Ma Yuyan Cui Shihong Deng Jihong Ding Guifeng Ding Yajuan Dong Linhong Duan Zhentao Fan Ling Fan Yang Fu Fen He Jing Ji Shuying Jin Lin Li Hong Li Hongying Liao Tao Lu Wei Luo Xiucui Lü Zhihui Ma Fengchun Ma Dafeng Shi Tianyun Sun Juying Sun Xiaotong Teng Hong Wang Jinhua Wang Ruihua Wang Ying Wang Zhengling Xi Jie Xu Minjuan Xu Zhihong Yan Qian Yang Cuirong Yang Yimei Yin Jie Yu Jinhua Yuan Wenjun Zhang Guanli Zhang Meihua Zhao Renfeng Zhong Yonghong Zhou Jian 2018Journal of Traditional Chinese Medicine2018,38,4:4
16A Sub-Nanostructural Transformable Nanozyme for Tumor Photocatalytic Therapy显示文摘The structural change-mediated catalytic activity regulation plays a significant role in the biological functions of natural enzymes.However,there is virtually no artificial nanozyme reported that can achieve natural enzyme-like stringent spatiotemporal structure-based catalytic activity regulation.Here,we report a subnanostructural transformable gold@ceria(STGC-PEG)nanozyme that performs tunable catalytic activities via near-infrared(NIR)light-mediated sub-nanostructural transformation.The gold core in STGC-PEG can generate energetic hot electrons upon NIR irradiation,wherein an internal sub-nanostructural transformation is initiated by the conversion between CeO;and electron-rich state of CeO;-x,and active oxygen vacancies generation via the hot-electron injection.Interestingly,the sub-nanostructural transformation of STGC-PEG enhances peroxidase-like activity and unprecedentedly activates plasmon-promoted oxidase-like activity,allowing highly efficient low-power NIR light(50 m W cm;)-activated photocatalytic therapy of tumors.Our atomic-level design and fabrication provide a platform to precisely regulate the catalytic activities of nanozymes via a light-mediated sub-nanostructural transformation,approaching natural enzyme-like activity control in complex living systems.Xi Hu Nan Wang Xia Guo Zeyu Liang Heng Sun Hongwei Liao Fan Xia Yunan Guan Jiyoung Lee Daishun Ling Fangyuan Li 2022Nano-Micro Letters2022,14,6:4
17Effect of transverse static magnetic field on radial microstructure of hypereutectic aluminum alloy during directional solidification显示文摘The effect of different scales thermoelectric magnetic convection(TEMC)on the radial solidification microstructure of hypereutectic Al alloy has been investigated under transverse static magnetic field during directional solidification,focusing on the formation of freckle.Our experimental and numerical simulation results indicate that the TEMC circulation at sample scale under transverse static magnetic field leads to the enrichment of solute Al on one side of the sample.The TEMC and the solute enrichment degree increase with the increase of magnetic field when the magnetic field increases to 0.5 T.The enrichment degree of solute elements under magnetic field is affected by temperature gradient and growth rate.The non-uniform distribution of solute Al in the radial direction of the sample results in the non-uniform distribution of primary dendrite arm spacing(PDAS).Moreover,the applied magnetic field can lead to freckle formation and its number increases with the increase of magnetic field.The change of freckle is consistent with the anisotropy TEMC caused by the anisotropy of primary dendrite or primary dendrite network under magnetic field.Finally,the mechanism of synergism effect of the anisotropy TEMC,the distribution of solute Al and the PDAS on freckle formation and evolution is studied during directional solidification under magnetic field.Shaodong Hu Long Hou Kang Wang Zhongmiao Liao Wen Zhu Aihua Yi Wenfang Li Yves Fautrelle Xi Li 2021Journal of Materials Science & Technology2021,,17:4
18Circular RNA circCCNB1 inhibits the migration and invasion of nasopharyngeal carcinoma through binding and stabilizing TJP1 mRNA显示文摘Nasopharyngeal carcinoma(NPC)is a malignant tumor that usually occurs in people from Southeast Asia and Southern China.NPC is prone to migration and invasion,leading to poor prognosis.A large number of circular RNAs(circ RNAs)exacerbate the process of metastasis in NPC;however,their underlying mechanisms remain unclear.We found that the circular RNA circ CCNB1,encoded by the oncogene CCNB1,was downregulated in NPC biopsies and cell lines.In vitro assays show that circ CCNB1 inhibits NPC cell migration and invasion.Moreover,circ CCNB1 induces a protein,nuclear factor 90(NF90),to bind and prolong the half-life of tight junction protein 1(TJP1)m RNA.Upregulation of TJP1 enhances tight junctions between cancer cells and inhibits NPC cell migration and invasion.This study reveals a novel biological function of circ CCNB1 in the migration and invasion of NPC by enhancing the tight junctions of cancer cells by binding to NF90 proteins and TJP1 m RNA,and may provide a potential therapeutic target for NPC.Mengyao Zhao Yian Wang Fenghua Tan Lingyun Liu Xiangchan Hou Chunmei Fan Le Tang Yongzhen Mo Yumin Wang Qijia Yan Zhaojian Gong Zheng Li Qianjin Liao Can Guo He Huang Xi Zeng Guiyuan Li Zhaoyang Zeng Wei Xiong Fuyan Wang 2022Science China(Life Sciences)2022,65,11:4
19Atractylenolide Ⅰ protects against lipopolysaccharide-induced disseminated intravascular coagulation by anti-inflammatory and anticoagulation effect显示文摘Objective:To investigate whether atractylenolide Ⅰ(ATL-Ⅰ) has protective effect on lipopolysaccharide(LPS)-induced disseminated intravascular coagulation(DIC) in vivo and in vitro,and explore whether NF-κB signaling pathway is involved in ATL-Ⅰ treatment.Methods:New Zealand white rabbits were injected with LPS through marginal ear vein over a period of 6h at a rate of 600 μg/kg(10 mL/h).Similarly,in the treatment groups,1.0,2.0,or 5.0 mg/kg ATL-Ⅰ were given.Both survival rate and organ function were tested,including the level of alanine aminotransferase(ALT),blood urine nitrogen(BUN),and TNF-α were examined by ELISA.Also haemostatic and fibrinolytic parameters in serum were measured.RAW 264.7 macrophage cells were administered with control,LPS,LPS + ATL-Ⅰ and ATL-Ⅰ alone,and TNF-α,phosphorylation(P)-IκBα,phosphorylation(P)-NF-κB(P65) and NF-κB(P65) were determined by Western blot.Results:The administration of LPS resulted in 73.3%mortality rate,and the increase of serum TNF-α,BUN and ALT levels.When ATL-Ⅰ treatment significantly increased the survival rate of LPS-induced DIC model,also improved the function of blood coagulation.And protein analysis indicated that ATL-Ⅰ remarkably protected liver and renal as decreasing TNF-α expression.In vitro,ATL-Ⅰ obviously decreased LPS-induced TNF-αproduction and the expression of P-NF-κB(P65),with the decrease of P-IκBα.Conclusions:ATL-Ⅰ has protective effect on LPS-induced DIC,which can elevate the survival rate,reduce organ damage,improve the function of blood coagulation and suppress TNF-α expression by inhibiting the activation of NF-κB signaling pathway.Xiao-Mei Tang Zhi-Kai Liao You-Wei Huang Xi Lin Liang-Cai Wu 2017Asian Pacific Journal of Tropical Medicine2017,10,6:4
20First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region.Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu 2021Science China(Physics,Mechanics & Astronomy)2021,64,8:3
