1Cold-chain food contamination as the possible origin of COVID-19 resurgence in Beijing显示文摘COVID-19,caused by SARS-CoV-2[1,2],has been contained in China through stringent non-pharmaceutical interventions.Border control and quarantine have effectively prevented the virus from being spread by infected travellers,but the risk of resurgence caused by other routes of introduction and transmission remains unclear,and current strategies to prevent resurgence could be flawed.Since July,SARS-CoV-2 RNA contaminations in frozen food imported from countries with ongoing epidemics have been reported in nine provinces in China[3,4].However,there is no robust evidence of COVID-19 outbreaks initiated by environmentto-human transmission.Here we add to evidence of such transmission by investigating the recent COVID-19 resurgence in Beijing.Xinghuo Pang Lili Ren Shuangsheng Wu Wentai Ma Jian Yang Lin Di Jie Li Yan Xiao Lu Kang Shichang Du Jing Du Jing Wang Gang Li Shuguang Zhai Lijuan Chen Wenxiong Zhou Shengjie Lai Lei Gao Yang Pan Quanyi Wang Mingkun Li Jianbin Wang Yanyi Huang Jianwei Wang COVID-19 Field Response Group COVID-19 Laboratory Testing Group 2020National Science Review2020,7,12:51
2Erianin,a novel dibenzyl compound in Dendrobium extract,inhibits lung cancer cell growth and migration via calcium/calmodulin-dependent ferroptosis显示文摘Ferroptosis,a novel form of programmed cell death,is characterized by iron-dependent lipid peroxidation and has been shown to be involved in multiple diseases,including cancer.Stimulating ferroptosis in cancer cells may be a potential strategy for cancer therapy.Therefore,ferroptosis-inducing drugs are attracting more attention for cancer treatment.Here,we showed that erianin,a natural product isolated from Dendrobium chrysotoxum Lindl,exerted its anticancer activity by inducing cell death and inhibiting cell migration in lung cancer cells.Subsequently,we demonstrated for the first time that erianin induced ferroptotic cell death in lung cancer cells,which was accompanied by ROS accumulation,lipid peroxidation,and GSH depletion.The ferroptosis inhibitors Fer-1 and Lip-1 but not Z-VAD-FMK,CQ,or necrostatin-1 rescued erianin-induced cell death,indicating that ferroptosis contributed to erianin-induced cell death.Furthermore,we demonstrated that Ca^(2+)/CaM signaling was a critical mediator of erianin-induced ferroptosis and that blockade of this signaling significantly rescued cell death induced by erianin treatment by suppressing ferroptosis.Taken together,our data suggest that the natural product erianin exerts its anticancer effects by inducing Ca^(2+)/CaMdependent ferroptosis and inhibiting cell migration,and erianin will hopefully serve as a prospective compound for lung cancer treatment.Peng Chen Qibiao Wu Jiao Feng Lili Yan Yitian Sun Shuiping Liu Yu Xiang Mingming Zhang Ting Pan Xiaying Chen Ting Duan Lijuan Zhai Bingtao Zhai Wengang Wang Ruonan Zhang Bi Chen Xuemeng Han Yicong Li Liuxi Chen Ying Liu Xingxing Huang Ting Jin Wenzheng Zhang Hong Luo Xiaohui Chen Yongqiang Li Qiujie Li Guohua Li Qin Zhang Lvjia Zhuo Zuyi Yang Huifen Tang Tian Xie Xiaoping Ouyang Xinbing Sui 2020Signal Transduction and Targeted Therapy2020,5,1:42
3Deep carbon cycles constrained by a large-scale mantle Mg isotope anomaly in eastern China显示文摘Although deep carbon recycling plays an important role in the atmospheric CO_2 budget and climate changes through geological time,the precise mechanisms remain poorly understood.Since recycled sedimentary carbonate through plate subduction is the main light-δ^(26)Mg reservoir within deep-Earth,Mg isotope variation in mantle-derived melts provides a novel perspective when investigating deep carbon cycling.Here,we show that the Late Cretaceous and Cenozoic continental basalts from 13 regions covering the whole of eastern China have low δ^(26)Mg isotopic compositions,while the Early Cretaceous basalts from the same area and the island arc basalts from circum-Paciic subduction zones have mantle-like or heavy Mg isotopic characteristics.hus,a large-scale mantle low δ^(26)Mg anomaly in eastern China has been delineated,suggesting the contribution of sedimentary carbonates recycled into the upper mantle,but limited into the lower mantle.his large-scale spatial and temporal variation of Mg isotopes in the mantle places severe constraints on deep carbon recycling via oceanic subduction.Shu-Guang Li Wei Yang Shah Ke Xunan Meng Hengci Tian Lijuan Xu Yongsheng He Jian Huang Xuan-Ce Wang Qunke Xia Weidong Sun Xiaoyong Yang Zhong-Yuan Ren Haiquan Wei Yongsheng Liu Fancong Meng Jun Yan 2017National Science Review2017,4,1:23
4The recommendations of Chinese Parkinson’s disease and movement disorder society consensus on therapeutic management of Parkinson’s disease显示文摘Background:Parkinson’s disease(PD)is a chronic,progressive and debilitating disease,which affects over 2.5 million people in China.PD is characterized clinically by resting tremor,muscular rigidity,bradykinesia and postural instability.As the disease progresses,additional complications can arise such as non-motor and neurobehavioral symptoms.Pharmacological treatment and surgical intervention for PD have been implemented in China.Until 10 years ago,there was lack of standardization for the management of PD in different regions and among different physicians,leading to different treatment levels in different regions and different physicians.Since then,the Chinese Parkinson’s Disease and Movement Disorder Society have published three versions of guidelines for the management of PD in China,in 2006,2009 and 2014,respectively.Correspondingly,the overall level of treatment for PD in China improved.Objectives:To update the treatment guidelines based on current foreign and domestic practice guidelines and clinical evidence,and to improve the treatment options available to physicians in the management of PD.Summary:A variety of treatment recommendations in the treatment guidelines have been proposed,including physical activity and disease-modifying medication,which should be initiated at the early-stage of the disease.The principles of dosage titration should be followed to avoid acute adverse reactions to the drugs,to achieve a satisfactory clinical effect with a low dose and to reduce the incidence of long-term motor complications.Moreover,different treatment strategies should be considered at different stages of the disease.Importantly,treatment guidelines and personalized treatments should be valued equally.A set of treatment recommendations has been developed to assist physicians to improve and optimize clinical outcomes for patients with PD in China.Shengdi Chen Piu Chan Shenggang Sun Haibo Chen Baorong Zhang Weidong Le Chunfeng Liu Guoguang Peng Beisha Tang Lijuan Wang Yan Cheng Ming Shao Zhenguo Liu Zhenfu Wang Xiaochun Chen Mingwei Wang Xinhua Wan Huifang Shang Yiming Liu Pingyi Xu Jian Wang Tao Feng Xianwen Chen Xingyue Hu Anmu Xie Qin Xiao 2016Translational Neurodegeneration2016,5,1:23
5Meeting 24-h movement guidelines: Prevalence, correlates, and the relationships with overweight and obesity among Chinese children and adolescents显示文摘Background:Meeting 24-h movement guidelines by children and adolescents has been associated with improved indicators of health,although it has been under-studied in China.Hence,this study aimed to investigate the prevalence of meeting the 24-h movement guidelines,its correlates,and its relationships with body mass index in children and adolescents in China.Methods:Cross-sectional data from the 2017 Youth Study in China of 114,072 children and adolescents(mean age=13.75 years,49.18%boys)were used.Meeting 24-h movement guidelines(60 min of daily moderate-to-vigorous physical activity,2 h of daily leisure screen time,911 h and 810 h nightly sleep duration for 613-year-olds and 1417-year-olds,respectively)and height and weight of all participants were assessed.The prevalence of meeting the 24-h movement guidelines and World Health Organization weight status categories were determined.Generalized linear models were used to determine the correlates of meeting the 24-h movement guidelines and the relationships of meeting the 24-h movement guidelines with overweight(OW)and obesity(OB).Results:Only 5.12%of Chinese children and adolescents met the 24-h movement guidelines,and 22.44%were classified as OW/OB.Older children and adolescents were less likely to meet the 24-h movement guidelines.Parental education level and family income were positively related to meeting the 24-h movement guidelines.Children and adolescents meeting the 24-h movement guidelines showed lower odds ratios for OW/OB.Compared with participants meeting the 24-h movement guidelines,boys in 4th6th grades met none of the recommendations(OR=1.22,95%CI:1.061.40),met the screen time recommendation only(OR=1.13,95%CI:1.011.28),met the nightly sleep duration recommendation only(OR=1.14,95%CI:1.031.28),and had significantly higher odds ratios for OW/OB.Similar trends were observed for girls in 4th6th grades:meeting none of the guidelines(OR=1.35,95%CI:1.141.59),meeting sleep duration guidelines only(OR=1.23,95%CI:1.081.39),and meeting moderate-to-vigorous physical activity+nightly sleep duration guidelines(OR=1.24,95%CI:1.011.54).For girls in 7th9th grades,the following trend was observed:meeting none of the guidelines(OR=1.30,95%CI:1.011.67).Conclusion:Very few Chinese children and adolescents met the 24-h movement guidelines.Age(negatively correlated),parental education level,and family income(both positively correlated)were correlates of meeting the 24-h movement guidelines.Children and adolescents meeting the 24-h movement guidelines were more likely to have lower risks for OW/OB,especially in the youngest age group(Grades 46);and girls in the middle age group(Grades 79)were also more likely to have lower risks for OW/OB.Further research studies should explore additional correlates and determinants for meeting the 24-h movement guidelines.Also,future studies should use longitudinal or interventional designs to determine the relationships between meeting the 24-h movement guidelines and OW/OB and other health indicators,while taking sex and age differences into account.Si-Tong Chen Yang Liu Mark S.Tremblay Jin-Tao Hong Yan Tang Zhen-Bo Cao Jie Zhuang Zheng Zhu Xueping Wu Lijuan Wang Yujun Cai Peijie Chen 2021Journal of Sport and Health Science2021,10,3:12
6School and community physical activity characteristics and moderate-to-vigorous physical activity among Chinese school-aged children: A multilevel path model analysis显示文摘Purpose: The purpose of this study was to examine the association between school and community physical activity(PA) characteristics and levels of moderate-to-vigorous physical activity(MVPA) among Chinese school children.Methods: Data were obtained from the 2016 Physical Activity and Fitness in China—The Youth Study project. Participants were 80,928 school children(Grades 4–12; 39,747 boys, 41,181 girls; mean age = 13 years) and 935 physical education(PE) teachers who completed a study survey.Independent variables included both school-related factors(school-level PA support, availability of and access to PA facilities, and the duration of school PE classes) and community-related factors(the frequency of sports events, sports training opportunities, availability of sports clubs and organizations, and access to PA facilities). The dependent variable was the children's self-reported participation in MVPA. The data were analyzed,in 2017, via multilevel modeling.Results: PA support from school administrators was the only school-level factor significantly related to children's participation in MVPA.Children's perceptions of the frequency of community-sponsored sports events, availability of sports clubs and organizations, and convenient access to PA facilities were associated with a high level of MVPA participation. In regard to residency in urban and rural areas, children attending urban schools who perceived high availability of PA facilities were associated with a low level of participation in MVPA.Conclusion: School support for PA and community PA resources are associated with MVPA among Chinese school children. School PA facilities appear underutilized among urban schools as evidenced by low levels of MVPA among school children.Lijuan Wang Yan Tang Jiong Luo 2017Journal of Sport and Health Science2017,6,4:11
7Transcriptomic landscape regulated by the 14 types of bone morphogenetic proteins(BMPs)in lineage commitment and differentiation of mesenchymal stem cells(MSCs)显示文摘Mesenchymal stem cells(MSCs)are ubiquitously-existing multipotent progenitors that can self-renew and differentiate into multiple lineages including osteocytes,chondrocytes,adipocytes,tenocytes and myocytes.MSCs represent one of the most commonly-used adult progenitors and serve as excellent progenitor cell models for investigating lineagespecific differentiation regulated by various cellular signaling pathways,such as bone morphogenetic proteins(BMPs).As members of TGFb superfamily,BMPs play diverse and important roles in development and adult tissues.At least 14 BMPs have been identified in mammals.Different BMPs exert distinct but overlapping biological functions.Through a comprehensive analysis of 14 BMPs in MSCs,we demonstrated that BMP9 is one of the most potent BMPs in inducing osteogenic differentiation of MSCs.Nonetheless,a global mechanistic view of BMP signaling in regulating the proliferation and differentiation of MSCs remains to be fully elucidated.Here,we conducted a comprehensive transcriptomic profiling in the MSCs stimulated by 14 types of BMPs.Hierarchical clustering analysis classifies 14 BMPs into three subclusters:an osteo/chondrogenic/adipogenic cluster,a tenogenic cluster,and BMP3 cluster.We also demonstrate that six BMPs(e.g.,BMP2,BMP3,BMP4,BMP7,BMP8,and BMP9)can induce ISmads effectively,while BMP2,BMP3,BMP4,BMP7,and BMP11 up-regulate Smad-independent MAP kinase pathway.Furthermore,we show that many BMPs can upregulate the expression of the signal mediators of Wnt,Notch and PI3K/AKT/mTOR pathways.While the reported transcriptomic changes need to be further validated,our expression profiling represents the first-of-its-kind to interrogate a comprehensive transcriptomic landscape regulated by the 14 types of BMPs in MSCs.Linghuan Zhang Qing Luo Yi Shu Zongyue Zeng Bo Huang Yixiao Feng Bo Zhang Xi Wang Yan Lei Zhenyu Ye Ling Zhao Daigui Cao Lijuan Yang Xian Chen Bin Liu William Wagstaff Russell R*Reid Hue H*Luu Rex C*Haydon Michael J*Lee Jennifer Moriatis Wolf Zhou Fu Tong-Chuan He Quan Kang 2019Genes & Diseases2019,6,3:11
8Nitric oxide alleviates aluminum-induced oxidative damage through regulating the ascorbateglutathione cycle in roots of wheat显示文摘The possible association with nitric oxide(NO) and ascorbate-glutathione(As A-GSH) cycle in regulating aluminum(Al) tolerance of wheat(Triticum aestivum L.) was investigated using two genotypes with different Al resistance. Exposure to Al inhibited root elongation, and triggered lipid peroxidation and oxidation of As A to dehydroascorbate and GSH to glutathione disulfide in wheat roots. Exogenous NO significantly increased endogenous NO levels, and subsequently alleviated Al-induced inhibition of root elongation and oxidation of As A and GSH to maintain the redox molecules in the reduced form in both wheat genotypes. Under Al stress, significantly increased activities and gene transcriptional levels of ascorbate peroxidase, glutathione reductase, and dehydroascorbate reductase,were observed in the root tips of the Al-tolerant genotype Jian-864. Nitric oxide application enhanced the activity and gene transcriptional level of these enzymes in both wheat genotypes. g-Glutamylcysteine synthetase was not significantly Researaffected by Al or NO, but NO treatments increased the activity of glutathione peroxidase and glutathione S-transferase to a greater extent than the Al-treated wheat seedlings. Proline was significantly decreased by Al, while it was not affected by NO.These results clearly suggest that NO protects wheat root against Al-induced oxidative stress, possibly through its regulation of the As A-GSH cycle.Chengliang Sun Lijuan Liu Yan Yu Wenjing Liu Lingli Lu Chongwei Jin Xianyong Lin 2015Journal of Integrative Plant Biology2015,57,6:10
9Re-Assessing Climatic Warming in China since 1900显示文摘The regional mean surface air temperature(SAT)in China has risen with a rate of 1.3–1.7℃(100 yr)^-1 since 1900,based on the recently developed homogenized observations.This estimate is larger than those[0.5–0.8℃(100 yr)^-1]adopted in the early National Reports of Climate Change in China.The present paper reviews the studies of the longterm SAT series of China,highlighting the homogenization of station observations as the key progress.The SAT series of China in early studies showed a prominent warm peak in the 1940s,mainly due to inhomogeneous records associated with site-moves of a number of stations from urban to outskirts in the early 1950s,thus leading to underestimates of the centennial warming trend.Parts of China were relatively warm around the 1940s but with differentphase interdecadal variations,while some parts were even relatively cool.This fact is supported by proxy data and could partly be explained by interdecadal changes in large-scale circulation.The effect of urbanization should have a minor contribution to the observed warming in China,although the estimates of such contributions for individual urban stations remain controversial.Further studies relevant to the present topic are discussed.Zhongwei YAN Yihui DING Panmao ZHAI Lianchun SONG Lijuan CAO Zhen LI 2020Journal of Meteorological Research2020,34,2:9

11Annual variations of black carbon over the Yangtze River Delta from 2015 to 2018显示文摘In this study,the black carbon (BC) measurements in the atmosphere of Nanjing,China were continuously conducted from 2015 to 2018 using a Model AE-33 aethalometer.By combining dataset of PM_(2.5),PM_(10),CO,NO_2,SO_2,O_3 and meteorological parameters,the temporal variations and the source apportionment of BC were given in this study.The results showed that the PM_(2.5) mass concentrations decreased in Nanjing,with an average annual rate of variation of 6.50μg/(m^3·year).Differently,the annual average concentrations of BC increased with an average annual variation rate of 214.71 ng/(m^3·year).The seasonal variations showed the pattern of BC mass concentrations in winter>autumn>spring>summer.The diurnal variations of BC mass concentrations showed a double-peak in all four seasons.The first peak occurred at approximately 7:00 in spring,summer and autumn and around 8:00 in winter.The second peak took place after 18:00.The average AAE (absorption ?ngstr?m exponent) was 1.26 with a maximum of 1.35 during wintertime and the lowest(1.12) during summertime.In addition,the AAE was smaller in the daytime than that at night,with a minimum occurring between 13:00 and 14:00.BC and visibility show a good power-function relationship at different humidity levels.The average values of the visibility thresholds of the BC mass concentrations in spring,summer,autumn and winter were 1.326,5.522,1.340 and 0.708μg/m^3,respectively.The greater the relative humidity,the smaller the visibility threshold for the BC mass concentrations was.Yue Tan Honglei Wang Shuangshuang Shi Lijuan Shen Chen Zhang Bin Zhu Song Guo zhijun Wu Ziyi Song Yan Yin Ankang Liu 2020Journal of Environmental Sciences2020,32,10:8
12Characterization of the aerosol chemical composition during the COVID-19 lockdown period in Suzhou in the Yangtze River Delta,China显示文摘To control the spread of COVID-19,rigorous restrictions have been implemented in China,resulting in a great reduction in pollutant emissions.In this study,we evaluated the air quality in the Yangtze River Delta during the COVID-19 lockdown period using satellite and ground-based data,including particle matter(PM),trace gases,water-soluble ions(WSIs) and black carbon(BC).We found that the impacts of lockdown policy on air quality cannot be accurately assessed using MODIS aerosol optical depth(AOD) data,whereas the tropospheric nitrogen dioxide(NO_(2)) vertical column density can well reflect the influences of these restrictions on human activities.Compared to the pre-COVID period,the PM_(2.5),PM_(10),NO_(2),carbon monoxide(CO),BC and WSIs during the lockdown in Suzhou were observed to decrease by 37.2%,38.3%,64.5%,26.1%,53.3% and 58.6%,respectively,while the sulfur dioxide(SO_(2)) and ozone(O_(3)) increased by 1.5% and 104.7%.The WSIs ranked in the order of NO_(3)~->NH_(4)^(+)>SO_(4)^(2-)>Cl~->Ca^(2+)>K^(+)>Mg^(2+)>Na + during the lockdown period.By comparisons with the ion concentrations during the pre-COVID period,we found that the ions NO 3-,NH 4 +,SO_(4)^(2-),Cl~-,Ca^(2+),K^(+) and Na^(+) decreased by 66.3%,48.8%,52.9%,56.9%,57.9% and 76.3%,respectively,during the lockdown,in contrast to Mg^(2+),which increased by 30.2%.The lockdown policy was found to have great impacts on the diurnal variations of Cl~-,SO_(4)^(2-),Na^(+) and Ca^(2+).Honglei Wang Qing Miao Lijuan Shen Qian Yang Yezheng Wu Heng Wei Yan Yin Tianliang Zhao Bin Zhu Wen Lu 2021Journal of Environmental Sciences2021,33,4:8

15In vitro differentiation of human adipose-derived mesenchymal stem cells into endothelial-like cells显示文摘The neovascularization of ischemic tis- sue is a crucial initial step for the functional rehabili- tation and wound healing. However, the short of seed cell candidate for the foundation of vascular network is still a big issue. Human adipose tissue derived mesenchymal stem cells (hADSCs), which possess multilineage potential, are capable of adipogenic, osteogenic, and chondrogenic differentiation. We examined whether this kind of stem cells could dif- ferentiate into endothelial-like cells and participate in blood vessel formation, and whether they could be used as an ideal cell source for therapeutic angio- genesis in ischemic diseases or vascularization of tissue constructs. The results showed that hADSCs, grown under appropriately induced conditions, dis- played characteristics similar to those of vessel en- dothelium. The differentiated cells expressed endo- thelial cell markers CD34 and vWF, and had high metabolism of acetylated low-density lipoprotein and prostacyclin. In addition, the induced cells were able to form tube-like structures when cultured on matrigel. Our data indicated that induced hADSCs could ex- hibit characteristics of endothelial cells. Therefore, these cells, as a source of human endothelial cells, may find many applications in such realms as engi- neering blood vessels, endothelial cell transplantation for myocardial regeneration, and induction of angio- genesis for treatment of regional ischemia.GUAN Lidong LI Shaoqing WANG Yunfang YUE Huimin LIU Daqing HE Lijuan BAI Cixian YAN Fang NAN Xue SHI Shuangshuang PEI Xuetao 2006Chinese Science Bulletin2006,51,15:6

17ESCRT-I Component VPS23A Sustains Salt Tolerance by Strengthening the SOS Module in Arabidopsis显示文摘The Salt-Overly-Sensitive(SOS)signaling module,comprising the sodium-transport protein SOS1 and the regulatory proteins SOS2 and SOS3,is well known as the central salt excretion system,which helps protect plants against salt stress.Here we report that VPS23A,a component of the ESCRT(endosomal sorting complex required for transport),plays an essential role in the function of the SOS module in conferring plant salt tolerance.VPS23A enhances the interaction of SOS2 and SOS3.In the presence of salt stress,VPS23A positively regulates the redistribution of SOS2 to the plasma membrane,which then activates the antiporter activity of SOS1 to reduce Na+accumulation in plant cells.Genetic evidence demonstrated that plant salt tolerance achieved by the overexpression of SOS2 and SOS3 dependeds on VPS23A.Taken together,our results revealed that VPS23A is a crucial regulator of the SOS module and affects the localization of SOS2 to the cell membrane.Moreover,the strong salt tolerance of Arabidopsis seedlings conferred by the engineered membrane-bound SOS2 revealed the significance of SOS2 sorting to the cell membrane in achieving its function,providing a potential strategy for crop salt tolerance engineering.Lijuan Lou Feifei Yu Miaomiao Tian Guangchao Liu Yaorong Wu Yujiao Wu Ran Xia Jose M.Pardo Yan Guo Qi Xie 2020Molecular Plant2020,13,8:5
18Analyzing and Forecasting Climate Change in Harbin City,Northeast China显示文摘Based on sounding data from 1975 to 2005 and TM/ETM+ remote sensing images in 1989, 2001 and 2007, the climate changes in Harbin City, Northeast China in recent 30 years were analyzed and forecasted. Results show that in the lower troposphere the meridional wind speed and mean annual wind speed decrease, and in the lower stratosphere the temperature decreases while the meridional wind speed increases significantly. In the study area, the climate is becoming warmer and wetter in the middle lower troposphere. The expansion of urban area has great effects on the surface air temperature and the wind speed, leading to the increase of the surface air temperature, the decrease of the surface wind speed, and the increase of the area of urban high temperature zone. The quantitative equations have been established among the surface air temperature, the carbon dioxide (CO2) concentration and the specific humidity (the water vapor content). It is predicted that the future increasing rate of the surface air temperature is 0.85℃/10yr if emission concentration of CO2 remains unchanged; if emission concentration of CO2 decreases to 75%, 50% and 25%, respectively, the surface air temperature will increase 0.65℃/10yr, 0.46℃/10yr and 0.27℃/10yr, respectively. The rise of the surface air temperature in the study area is higher than that of the global mean temperature forecasted by IPCC.ZHANG Lijuan LIU Dong YAN Xiaodong ZHOU Dongying ZHENG Hong SU Lianling 2011Chinese Geographical Science2011,21,1:4
19Prognostic value of interim ^(18)F-FDG PET/CT in diffuse large B-cell lymphoma显示文摘Objective: Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease. The prognostic factor currently used is not accurate enough to predict the outcomes of patients with DLBCL. The prognostic significance of interim PET/CT in DLBCL remains controversial. The aim of this study is to determine the predictive value of interim 18F-FDG PET/CT after first-line treatment in patients with DLBCL. Methods: Thirty-two patients with DLBCL underwent baseline, interim and post-treatment 18F-FDG PET/CT scans. Imaging results were analyzed for the survival of patients via software SPSS 13.0, retrospectively. Results: Thirty-one of the 32 patients were treated with R-CHOP regimen, and interim 18F-FDG PET/CT of 24 patients was performed after 2 cycles of treatment. After a median follow-up period of 16.7 months, the 2-year progression-free survival (PFS) rates were significantly different between the groups above and below SUV max cut-off value of 2.5 (P=0.039). No significant differences were found in the 2-year PFS rates if SUV max cut-off values were set as 2.0 and 3.0, respectively (P=0.360; P=0.113). Conclusions: Interim PET/CT could predict the prognosis of DLBCL patients with the SUV max cut-off value of 2.5, but more clinical data should be concluded to confirm this conclusion.Zhitao Ying Xuejuan Wang Yuqin Song Wen Zheng Xiaopei Wang Yan Xie Ningjing Lin Meifeng Tu Lingyan Ping Weiping Liu Lijuan Deng Chen Zhang Zhi Yang Jun Zhu 2013Chinese Journal of Cancer Research2013,25,1:4
20Water-driven photoluminescence reversibility in CsPbBr_(3)/PDMSPUa composite显示文摘Strong ionic character endows all-inorganic perovskite nanocrystals(NCs)with particular optoelectronic features when interacting with common polar solvents,such as water.However,the interaction mechanism of water affecting perovskite NCs is still lack of in-depth understanding.This study systematically explores the roles of water on CsPbBr_(3) nanocrystals(CNCs)by finely controlling the polymer coating degree of polydimethylsiloxane-based polyurea(PDMS-PUa).Through this coating,the effect of water on CNCs is found to experience from“fluorescence quenching”owing to irreversible crystal decomposition towards“forward fluorescence reversibility”by crystal destruction and recrystallization.With gradually enhanced coating,a phenomenon of“reverse fluorescence reversibility”is further observed in that water begins to passivate the CNCs’defect states.Finally,“fluorescent balance”can be achieved with a thick enough coating,where water can hardly contact with the CNCs.Inspired by the fluorescence reversible mechanism discovered,a new wearable intelligent sensing skin is demonstrated by using the CsPbBr_(3)/PDMS-PUa composite as raw material.Both water contact and humidity change can be perceived through photoluminescence(PL)intensity,corresponding to stimuli-responsive sensory nerves of human skin.It is expected that these findings will shed some new lights on perovskite NCs.Junhu Cai Chenhui Wang Xinpei Hu Yuanyuan Ye Lijuan Zhong Enguo Chen Yun Ye Sheng Xu Jie Sun Qun Yan Tailiang Guo 2022Nano Research2022,15,7:4
