3Breast cancer incidence and mortality in women in China: temporal trends and projections to 2030显示文摘Objective:Breast cancer was the most common cancer and the fifth cause of cancer deaths among women in China in 2015.The evaluation of the long-term incidence and mortality trends and the prediction of the future burden of breast cancer could provide valuable information for developing prevention and control strategies.Methods:The burden of breast cancer in China in 2015 was estimated by using qualified data from 368 cancer registries from the National Central Cancer Registry.Incident cases and deaths in 22 cancer registries were used to assess the time trends from 2000 to 2015.A Bayesian age-period-cohort model was used to project the burden of breast cancer to 2030.Results:Approximately 303,600 new cases of breast cancer(205,100 from urban areas and 98,500 from rural areas)and 70,400 breast cancer deaths(45,100 from urban areas and 24,500 from rural areas)occurred in China in 2015.Urban regions of China had the highest incidence and mortality rates.The most common histological subtype of breast cancer was invasive ductal carcinoma,followed by invasive lobular carcinoma.The age-standardized incidence and mortality rates increased by 3.3%and 1.0%per year during 2000–2015,and were projected to increase by more than 11%until 2030.Changes in risk and demographic factors between 2015 and 2030 in cases are predicted to increase by approximately 13.3%and 22.9%,whereas deaths are predicted to increase by 13.1%and 40.9%,respectively.Conclusions:The incidence and mortality of breast cancer continue to increase in China.There are no signs that this trend will stop by 2030,particularly in rural areas.Effective breast cancer prevention strategies are therefore urgently needed in China.Shaoyuan Lei Rongshou Zheng Siwei Zhang Ru Chen Shaoming Wang Kexin Sun Hongmei Zeng Wenqiang Wei Jie He 2021Cancer Biology & Medicine2021,18,3:53
4Global patterns of breast cancer incidence and mortality:A population-based cancer registry data analysis from 2000 to 2020显示文摘Background:Breast cancer is the most commonly diagnosed cancer and leading cause of cancer death among women worldwide but has patterns and trends which vary in different countries.This study aimed to evaluate the global patterns of breast cancer incidence and mortality and analyze its temporal trends for breast cancer prevention and control.Methods:Breast cancer incidence and mortality data in 2020 were obtained from the GLOBOCAN online database.Continued data from the Cancer Incidence in Five Continents Time Trends,the International Agency for Research on cancer mortality and China National Central Cancer Registry were used to analyze the time trends from 2000 to 2015 through Joinpoint regression,and annual average percent changes of breast cancer incidence and mortality were calculated.Association between Human Development Index and breast cancer incidence and mortality were estimated by linear regression.Results:There were approximately 2.3 million new breast cancer cases and 685,000 breast cancer deaths worldwide in 2020.Its incidence and mortality varied among countries,with the age-standardized incidence ranging from the highest of 112.3 per 100,000 population in Belgium to the lowest of 35.8 per 100,000 population in Iran,and the age-standardized mortality from the highest of 41.0 per 100,000 population in Fiji to the lowest of 6.4 per 100,000 population in South Korea.The peak age of breast cancer in some Asian and African countries were over 10 years earlier than in European or American countries.As for the trends of breast cancer,the age-standardized incidence rates significantly increased in China and South Korea but decreased in the United States of America(USA)during 2000-2012.Meanwhile,the age-standardized mortality rates significantly increased in China and South Korea but decreased in the United Kingdom,the USA,and Australia during 2000 and 2015.Conclusions:The global burden of breast cancer is rising fast and varies greatly among countries.The incidence and mortality rates of breast cancer increased rapidly in China and South Korea but decreased in the USA.Increased health awareness,effective prevention strategies,and improved access to medical treatment are extremely important to curb the snowballing breast cancer burden,especially in the most affected countries.Shaoyuan Lei Rongshou Zheng Siwei Zhang Shaoming Wang Ru Chen Kexin Sun Hongmei Zeng Jiachen Zhou Wenqiang Wei 2021Cancer Communications2021,41,11:55

6LA-ICP-MS zircon U-Pb dating and phenocryst EPMA of dikes, Guocheng, Jiaodong Peninsula: Implications for North China Craton lithosphere evolution显示文摘Widespread dike swarm, including diorite-, monzonite-porphyry and lamprophyre, intruded in the al- tered breccia gold deposits along basin marginal faults, Guocheng, Jiaodong Peninsula. Petrography exhibits biotite enclaves in amphibole phenocrysts and the presence of acicular apatites in these dikes. Electron probe microanalyses (EPMA) show that the amphibole and clinopyroxene phenocryst’s mantle in diorite porphyry and lamprophyre respectively has sharply higher MgO (Mg#) and Cr2O3 contents in contrast to their cores. The plagioclase phenocryst in monzonite porphyry has reverse zoning. These results indicate that the magma mixing between mantle-derived mafic and crust-derived felsic magmas occurred in the original process of the dikes. Zircon cathodoluminescence (CL) images show well-developed magmatic oscillatory zones and the acquired LA-ICP-MS zircon U-Pb weighted mean 206Pb/238U ages are 114±2 Ma (MSDW=1.5) for monzonite porphyry (GS1) and 116±1 Ma (MSDW=0.8) for diorite porphyry (GS2), respectively. Earlier magmatic events in the northwest Jiaodong Peninsula represented by some inherited or captured zircons also occur in these dikes. Magmatic zircons from GS1 and GS2 display consistent chondrite-normalized REE patterns and Nb/Ta values, implying that they may share a similar or same source. HREE enrichment and obvious negative Eu anomalies of these zircons preclude garnet presented in their source. Our results, combined with preciously pub- lished data, indicate that dike intrusion and gold mineralization among quartz vein, altered tectonite and altered breccia gold deposits are broadly contemporaneous throughout the Jiaodong Peninsula. These also imply that the intensive crust-mantle interaction and asthenospheric underplating had oc- curred in the Early Cretaceous in the Peninsula, together with foundering of lower crust in the early Mesozoic, representing the different stages of lithosphere thinning in the North China Craton (NNC).TAN Jun WEI JunHao GUO LingLi ZHANG KeQing YAO ChunLiang LU JianPei LI HongMei 2008Science China Earth Sciences2008,51,10:23
7Annual cost of illness of stomach and esophageal cancer patientsin urban and rural areas in China: A multi-center study显示文摘Objective: Stomach and esophageal cancer are imposing huge threats to the health of Chinese people whereas there were few studies on the financial burden of the two cancers.Methods: Costs per hospitalization of all patients with stomach or esophageal cancer discharged between September 2015 and August 2016 in seven cities/counties in China were collected, together with their demographic information and clinical details. Former patients in the same hospitals were sampled to collect information on annual direct non-medical cost, indirect costs and annual number of hospitalization. Annual direct medical cost was obtained by multiplying cost per hospitalization by annual number of hospitalization. Annual cost of illness(ACI)was obtained by adding the average value of annual direct medical cost, direct non-medical cost and indirect cost,stratified by sex, age, clinical stage, therapy and pathologic type in urban and rural areas. Costs per hospitalization were itemized into eight parts to calculate the proportion of each part. All costs were converted to 2016 US dollars(1 USD=6.6423 RMB).Results: Totally 19,986 cases were included, predominately male. Mean ages of stomach cancer and urban patients were lower than that of esophageal cancer and rural patients. ACI of stomach and esophageal cancer patients were $10,449 and $13,029 in urban areas, and $2,927 and $3,504 in rural areas, respectively. Greater ACI was associated with male, non-elderly patients as well as those who were in stage I and underwent surgeries.Western medicine fee took the largest proportion of cost per hospitalization.Conclusions: The ACI of stomach and esophageal cancer was tremendous and varied substantially among the population in China. Preferential policies of medical insurance should be designed to tackle with this burden and further reduce the health care inequalities.Zhixun Yang Hongmei Zeng Ruyi Xia Qian Liu Kexin Sun Rongshou Zheng Siwei Zhang Changfa Xia He Li Shuzheng Liu Zhiyi Zhang Yuqin Liu Guizhou Guo Guohui Song Yigong Zhu Xianghong Wu Bingbing Song Xianzhen Liao Yanfang Chen Wenqiang Wei Guihua Zhuang Wanqing Chen 2018Chinese Journal of Cancer Research2018,30,4:22
8Wnt and BMP signaling crosstalk in regulating dental stem cells:Implications in dental tissue engineering显示文摘Tooth is a complex hard tissue organ and consists of multiple cell types that are regulated by important signaling pathways such as Wnt and BMP signaling.Serious injuries and/or loss of tooth or periodontal tissues may significantly impact aesthetic appearance,essential oral functions and the quality of life.Regenerative dentistry holds great promise in treating oral/dental disorders.The past decade has witnessed a rapid expansion of our understanding of the biological features of dental stem cells,along with the signaling mechanisms governing stem cell self-renewal and differentiation.In this review,we first summarize the biological characteristics of seven types of dental stem cells,including dental pulp stem cells,stem cells from apical papilla,stem cells from human exfoliated deciduous teeth,dental follicle precursor cells,periodontal ligament stem cells,alveolar bone-derived mesenchymal stem cells(MSCs),and MSCs from gingiva.We then focus on how these stem cells are regulated by bone morphogenetic protein(BMP)and/or Wnt signaling by examining the interplays between these pathways.Lastly,we analyze the current status of dental tissue engineering strategies that utilize oral/dental stem cells by harnessing the interplays between BMP and Wnt pathways.We also highlight the challenges that must be addressed before the dental stem cells may reach any clinical applications.Thus,we can expect to witness significant progresses to be made in regenerative dentistry in the coming decade.Fugui Zhang Jinlin Song Hongmei Zhang Enyi Huang Dongzhe Song Viktor Tollemar Jing Wang Jinhua Wang Maryam Mohammed Qiang Wei Jiaming Fan Junyi Liao Yulong Zou Feng Liu Xue Hu Xiangyang Qu Liqun Chen Xinyi Yu Hue H.Luu Michael J.Lee Tong-Chuan He Ping Ji 2016Genes & Diseases2016,3,4:16
9Colorectal cancer burden and trends:Comparison between China and major burden countries in the world显示文摘Objective:To summarize the colorectal cancer(CRC)burden and trend in the world,and compare the difference of CRC burden between other countries and China.Methods:Incidence and mortality data were extracted from the GLOBOCAN2018 and Cancer Incidence in Five Continents.Age-specific incidence trend was conducted by Joinpoint analysis and average annual percent changes were calculated.Results:About 1.85 million new cases and 0.88 million deaths were expected in 2018 worldwide,including 0.52 million(28.20%)new cases and 0.25 million(28.11%)deaths in China.Hungary had the highest age-standardized incidence and mortality rates in the world,while for China,the incidence and mortality rates were only half of that.CRC incidence and mortality were highly correlated with human development index(HDI).Unlike the rapid increase in Republic of Korea and the downward trend in Canada and Australia,the age-standardized incidence rates by world standard population in China and Norway were rising gradually.The age-specific incidence rate in the age group of 50-59 years in China was increasing rapidly,while in Republic of Korea and Canada,the fastest growing age group was 30-39 years.Conclusions:The variations of CRC burden reflect the difference of risk factors,as well as levels of HDI and screening(early detection activities).The burden of CRC in China is high,and the incidence of CRC continues to increase,which may lead to a sustained increase in the burden of CRC in China in the future.Screening should be expanded to control CRC,and focused on young people in China.Jiachen Zhou Rongshou Zheng Siwei Zhang Hongmei Zeng Shaoming Wang Ru Chen Kexin Sun Minjuan Li Jianhua Gu Guihua Zhuang Wenqiang Wei 2021Chinese Journal of Cancer Research2021,33,1:16
10Cancer statistics in Chinese older people,2022:current burden,time trends,and comparisons with the US,Japan,and the Republic of Korea显示文摘Largely due to population ageing,the cancer burden from older people has been rising,which imposed considerable pressure on current Chinese healthcare system.We provide comprehensive information about cancer burden of Chinese older people based on the most recent data from National Central Cancer Registry of China.The logarithmic linear regression was used to project the current cancer burden in 2022,and Joinpoint regression was used for temporal trend analysis from 2000 to 2017.We also estimated cancer statistics of older people in the US,Japan and the Republic of Korea for comparisons.It is estimated that 2.79 million cases and 1.94 million deaths occur for Chinese older people,representing 55.8%and 68.2%of cases and deaths in all population in 2022.The overall cancer incidence rate gradually increased among older women,while the mortality rates declined for both sexes.Notably,approximately 10.0%of all cases and 17.7%of all deaths are from people aged over 80 years,and cancer incidence and mortality in this age group showed upward trends for women.Lung cancer and digestive cancers are the leading cancer types for Chinese older people.Compared with other countries,China has lower incidence rates but higher mortality rates for older people.The rapidly growing burden of prostate cancer,breast cancer,colorectal cancer,and declines in esophageal cancer,stomach cancer,and liver cancer among older people indicate the cancer pattern in China is being in a transition stage to that in developed countries.Our findings imply that it should be the national health priority to meet the growing demands for cancer diagnosis,treatment and care services from the older people as the rapid population ageing in next few decades.Wen Ju Rongshou Zheng Siwei Zhang Hongmei Zeng Kexin Sun Shaoming Wang Ru Chen Li Li Wenqiang Wei Jie He 2023Science China(Life Sciences)2023,66,5:15
11Reproductive management through integration of PGD and MPS-based noninvasive prenatal screening/diagnosis for a family with GJB2-associated hearing impairment显示文摘A couple with a proband child of GJB2(encoding the gap junction protein connexin 26)-associated hearing impairment and a previous pregnancy miscarriage sought for a reproductive solution to bear a healthy child. Our study aimed to develop a customized preconception-to-neonate care trajectory to fulfill this clinical demand by integrating preimplantation genetic diagnosis(PGD), noninvasive prenatal testing(NIPT), and noninvasive prenatal diagnosis(NIPD) into the strategy. Auditory and genetic diagnosis of the proband child was carried out to identify the disease causative mutations. The couple then received in-vitro-fertilization treatment, and eight embryos were obtained for day 5 biopsy. PGD was performed by short-tandem-repeat linkage analysis and Sanger sequencing of GJB2 gene. Transfer of a GJB2 c.235del C heterozygous embryo resulted in a singleton pregnancy. At the 13 th week of gestation, genomic DNA(g DNA) from the trio family and cell-free DNA(cf DNA) from maternal plasma were obtained for assessment of fetal chromosomal aneuploidy and GJB2 mutations. NIPT and NIPD showed the absence of chromosomal aneuploidy and GJB2-associated disease in the fetus, which was later confirmed by invasive procedures and postnatal genetic/auditory diagnosis. This strategy successfully prevented the transmission of hearing impairment in the newborn, thus providing a valuable experience in reproductive management of similar cases and potentially other monogenic disorders.XIONG WenPing WANG DaYong GAO Yuan GAO Ya WANG HongYang GUAN Jing LAN Lan YAN JunHao ZONG Liang YUAN Yuan DONG Wei HUANG SeXin WU KeLiang WANG YaoShen WANG ZhiLi PENG HongMei LU YanPing XIE LinYi ZHAO Cui WANG Li ZHANG QiuJing GAO Yun LI Na YANG Ju YIN ZiFang HAN Bing WANG Wei CHEN Zi-Jiang WANG QiuJu 2015Science China(Life Sciences)2015,58,9:12
12Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
13Nitrogen-doped fluorescence carbon dots as multi-mechanism detection for iodide and curcumin in biological and food samples显示文摘Iodine ion is one of the most indispensable anions in living organisms,particularly being an important substance for the synthesis of thyroid hormones.Curcumin is a yellow-orange polyphenol compound derived from the rhizome of Curcuma longa L.,which has been commonly used as a spice and natural coloring agent,food additives,cosmetics as well as Chinese medicine.However,excess curcumin may cause DNA inactivation,lead to a decrease in intracellular ATP levels,and trigger the tissue necrosis.Therefore,quantitative detection of iodine and curcumin is of great significance in the fields of food and life sciences.Herein,we develop nitrogen-doped fluorescent carbon dots(NCDs)as a multi-mechanism detection for iodide and curcumin in actual complex biological and food samples,which was prepared by a one-step solid-phase synthesis using tartaric acid and urea as precursors without adding any other reagents.An assembled NCDs-Hg^(2+) fluorescence-enhanced sensor for the quantitative detection of I^(-) was established based on a fluorescence“turn-off-on”mechanism in a linear range of 0.3-15μM with a detection limit of 69.4 nM and successfully quantified trace amounts of I^(-) in water samples and urine sample.Meanwhile,the as-synthesized NCDs also can be used as a fluorescent quenched sensor for curcumin detection based on the synergistic internal filtration effect(IFE)and static quenching,achieving a good linear range of 0.1-20μM with a satisfactory detection limit of 29.8 nM.These results indicate that carbon dots are potential sensing materials for iodine and curcumin detection for the good of our health.Xiaodan Tang Hongmei Yu Brian Bui Lingyun Wang Christina Xing Shaoyan Wang Mingli Chen Zhizhi Hu Wei Chen 2021Bioactive Materials2021,6,6:11
14Evaluating efficacy of screening for upper gastrointestinal cancer in China:a study protocol for a randomized controlled trial显示文摘Objective: To evaluate the efficacy and feasibility of screening procedure for upper gastrointestinal cancer in both high-risk and non-high-risk areas in China.Setting: Seven cities/counties, representing three economical-geographical regions(Eastern, Central and Western) in China, were selected as screening centers: three in high-risk areas and four in non-high-risk areas.Participants: Villages/communities in these seven centers regarded as clusters were randomly assigned to either intervention group(screening by endoscopic examination) or control group(with normal community care) in a 1:1ratio stratified by each center. Eligible participants are local residents aged 40–69 years in the selected villages/communities with no history of cancer or endoscopic examination in the latest 3 years who are mentally and physically competent. Those who are not willing to take endoscopic examination or are unwilling to sign the consent form are excluded from the study. Totally 140,000 participants will be enrolled.Interventions: In high-risk areas of upper gastrointestinal cancer, all subjects in screening group will be screened by endoscopy. In non-high-risk areas, 30% of the subjects in screening group, identified through a survey,will be screened by endoscopy.Primary and secondary outcome measures: The primary outcome is the mortality caused by upper gastrointestinal cancer. The secondary outcomes include detection rate, incidence rate, survival rate, and clinical stage distribution. Additional data on quality of life and cost-effectiveness will also be collected to answer important questions regarding screening effects.Conclusions: Screening strategy evaluated in those areas with positive findings may be promoted nationally and applied to the majority of Chinese people. On the other hand, negative findings will provide scientific evidence for abandoning a test and shifting resources elsewhere.Trial registration: The study has been registered with the Protocol Registration System in Chinese Clinical Trial Registry.wanqing chen hongmei zeng ru chen ruyi xia zhixun yang changfa xia rongshou zheng wenqiang wei guihua zhuang xueqin yu jie he 2017Chinese Journal of Cancer Research2017,29,4:11
15Endogenous neurogenesis in adult mammals after spinal cord injury显示文摘During the whole life cycle of mammals,new neurons are constantly regenerated in the subgranular zone of the dentate gyrus and in the subventricular zone of the lateral ventricles.Thanks to emerging methodologies,great progress has been made in the characterization of spinal cord endogenous neural stem cells(ependymal cells) and identification of their role in adult spinal cord development.As recently evidenced,both the intrinsic and extrinsic molecular mechanisms of ependymal cells control the sequential steps of the adult spinal cord neurogenesis.This review introduces the concept of adult endogenous neurogenesis,the reaction of ependymal cells after adult spinal cord injury(SCI),the heterogeneity and markers of ependymal cells,the factors that regulate ependymal cells,and the niches that impact the activation or differentiation of ependymal cells.Hongmei Duan Wei Song Wen Zhao Yudan Gao Zhaoyang Yang Xiaoguang Li 2016Science China(Life Sciences)2016,59,12:10
16Outcomes in refractory diffuse large B-cell lymphoma:results fromamulticenter real-world study in China显示文摘Background:Diffuse large B-cell lymphoma(DLBCL)patients refractory to rituximab-based immunochemotherapy have a dismal prognosis.However,the definition of refractory DLBCL remains inconsistent and no large cohort study data is available from Asian countries.To validate the definition and outcomes of refractory DLBCL in China,we conducted a multicenter,retrospective cohort study.Methods:The REtrospective AnaLysis of Treatment REspoNse of refractory DLBCL(REAL-TREND)study was performed using real-world data from 8 centers in China.DLBCL patients with curative intent were included in the REAL-TREND dataset.Overall survival(OS)was estimated using the Kaplan-Meier method and compared by the log-rank test.Due to heterogeneity in response rates among different centers,the response rates of refractory patients were pooled using random-effect models.Multivariate survival analysis was performed using the Cox regression model.Results:A total of 2778 DLBCL patients diagnosed between January,2010 and December,2015 were enrolled to this study.After validating previous definitions,the SCHOLAR-1 study was most suitable to define refractory DLBCL.The estimated 5-year cumulative incidence of refractory patients was 20%(95% confidence Interval[CI]=18%-22%).After the determination of refractory disease,overall response rate and complete remission rate were 30%(95%CI=22%-38%)and 9%(95%CI=4%-15%),respectively.Patients with either no response to immunochemotherapy or relapse within 12 months after stem-cell transplantation had inferior survival with a median OS of 5.9 months(95%CI=5.5-7.1 months)and 2-year OS rate of 16%(95%CI=12%-20%).International prognostic index score 4-5(hazard ratio[HR]=2.22;95%CI=1.47-3.35),central nervous systemrelapse(HR=1.43;95%CI=1.04-1.97),and best response status(HR=2.68;95%CI=1.42-5.03 for partial remission.HR=5.97,95%CI=3.21-11.11 for stable disease/progressive disease)were independent unfavorable prognostic factors.Conclusions:This is the first large-scale Asian cohort study focusing on outcomes of refractory DLBCL.The definition of the SCHOLAR-1 study identifies patients with homogenously inferior survival,thus is appropriate to select refractory DLBCL.Due to poor clinical outcomes in the rituximab era,patients with refractory DLBCL may be potential candidates for novel treatment modalities.Shuo Wang Li Wang Jianda Hu Wenbin Qian Xi Zhang Yu Hu Qi Zhu Bobin Chen Depei Wu Chung-Chou H.Chang Pengpeng Xu Xiaoyun Zheng Juying Wei Yao Liu Guohui Cui Yong Tang Yan Ma Haiwen Huang Hongmei Yi Weili Zhao 2021Cancer Communications2021,41,3:10
17Outcome of multimodal MRI-guided intravenous thrombolysis in patients with stroke with unknown time of onset显示文摘Objective Intravenous tissue plasminogen activator(tPA)is the standard therapy for patients with acute ischaemic stroke(AIS)within 4.5 hours of onset.Recent trials have expanded the endovascular treatment window to 24 hours.We investigated the efficacy and safety of using multimodal MRI to guide intravenous tPA treatment for patients with AIS of unknown time of onset(UTO).Methods Data on patients with AIS with UTO and within 4.5 hours of onset were reviewed.Data elements collected and analysed included:demographics,National Institutes of Health Stroke Scale(NIHSS)score at baseline and 2 hours,24 hours,7 days after thrombolysis and before discharge,the modified Rankin Scale(mRS)score at 3 months after discharge,imaging findings and any adverse event.results Forty-two patients with UTO and 62 in control group treated within 4.5 hours of onset were treated with intravenous tPA.The NIHSS scores after thrombolysis and/or before discharge in UTO group were significantly improved compared with the baseline(p<0.05).Between the two groups,no significant differences in NIHSS score were observed(p>0.05).Utilising the non-inferiority test,to compare mRS scores(0-2)at 3 months between the two groups,the difference was 5.2%(92%CI,OR 0.196).Patients in the UTO group had mRS scores of 0-2,which were non-inferior to the control group.Their incidence of adverse events was similar.Conclusions Utilising multimodal MRI to guide intravenous only thrombolysis for patients with AIS with UTO was safe and effective.In those patients with AIS between 6 and 24 hours of time of onset but without large arterial occlusion,intravenous thrombolysis could be considered an option.Jie Zhao Hongmei Zhao Runtao Li Jiangtao Li Chang Liu Juan Lv Yanan Li Wei Liu Dongpu Ma Huaihai Hao Xinguang Xiao Junzhong Liu Yongfeng Yin Rongli Liu Qiaoyan Yu Yingjie Wei Pengyan Li Yue Wang Runqing Wang 2019Stroke & Vascular Neurology2019,4,1:8
18Preparation and characterization of microcapsule containing epoxy resin and its self-healing performance of anticorrosion covering material显示文摘Microencapsulated healing agents that possess adequate strength,long shelf-life,and excellent bonding to the host material are required for self-healing materials. The in situ encapsulation method is demonstrated over an order of magnitude size reduction for the preparation of urea-formaldehyde(UF) capsules filled with a healing agent,a mixture epoxy resin of the epoxy 711 and E-51. Capsules with diameters as small as about 100 μm are achieved under the agitation rate of 800 r min-1. The capsules possess a uniform UF shell wall(4 μm average thickness) . By using the analysis of scanning electronic microscope(SEM) ,thermal analysis(TG-DTA) and FTIR,the characteristics of the microcapsules were investigated respectively. Successful self-healing has been demonstrated for anticorrosion covering materials with microcapsules.LIAO LePing ZHANG Wei XIN Yi WANG HongMei ZHAO Yang LI WuJun 2011Chinese Science Bulletin2011,56,4:8

20Application of the sodium hyaluronate-CNTF scaffolds in repairing adult rat spinal cord injury and facilitating neural network formation显示文摘The present study aimed to explore the potential of the sodium hyaluronate-CNTF (ciliary neurotrophic factor) scaffold in activating endogenous neurogenesis and facilitating neural network re-formation after the adult rat spinal cord injury (SCI). After completely cutting and removing a 5-mm adult rat T8 segment, a sodium hyaluronate-CNTF scaffold was implanted into the lesion area. Dil tracing and immunofluorescence staining were used to observe the proliferation, differentiation and integration of neural stem cells (NSCs) after SCI. A planar multielectrode dish system (MED64) was used to test the electrophysiological characteristics of the regenerated neural network in the lesioned area. Electrophysiology and behavior evaluation were used to evaluate functional recovery of paraplegic rat hindlimbs. The Dil tracing and immunofluorescence results suggest that the sodium hyaluronate-CNTF scaffold could activate the NSCs originating from the spinal cord ependymal, and facilitate their migration to the lesion area and differentiation into mature neurons, which were capable of forming synaptic contact and receiving glutamatergic excitatory synaptic input. The MED64 results suggest that functional synapsis could be established among regenerated neurons as well as between regenerated neurons and the host tissue, which has been evidenced to be glutamatergic excitatory synapsis. The electrophysiology and behavior evaluation results indicate that the paraplegic rats’ sensory and motor functions were recovered in some degree. Collectively, this study may shed light on paraplegia treatment in clinics.Yabin Xie Wei Song Wen Zhao Yudan Gao Junkui Shang Peng Hao Zhaoyang Yang Hongmei Duan Xiaoguang Li 2018Science China(Life Sciences)2018,61,5:6
