1Increasing the frequency of CIK cells adoptive immunotherapy may decrease risk of death in gastric cancer patients显示文摘AIM: To analyze the correlation between cytokineinduced killer (CIK) cells adoptive immunotherapy and cancer-related death in gastric cancer patients. METHODS: One hundred and fifty-six gastric cancer patients after operation at the Third Affiliated Hospital of Soochow University were enrolled in this study. Their clinical data including demographic characteristics, operation time, tumor size, pathological type and staging, tumor metastasis, outcome of chemotherapy or CIK cells adoptive immunotherapy, survival time or time of death were collected with a standard structured questionnaire. Kaplan-Meier method was used to estimate the median survival time, and the 2- and 5- year survival rates. Hazard risk (HR) and 95% confidence interval (95% CI) of CIK cells adoptive immunotherapy for gastric cancer were calculated using the two-stage time-dependent covariates Cox model. RESULTS: The survival time of gastric cancer patients was longer after CIK cells adoptive immunotherapy than after chemotherapy (χ 2 = 10.907, P = 0.001). The median survival time of gastric cancer patients was also longer after CIK cells adoptive immunotherapy than after chemotherapy (49 mo vs 27 mo, P < 0.05). The 2- and 5-year survival rates of gastric cancer patients were significantly higher after CIK cells adoptive immunotherapy than after chemotherapy (73.5% vs 52.6%, 40.4% vs 23.9%, P < 0.05). A significant difference was observed in the survival curve for patients who received CIK cells adoptive immunotherapy (0, 1-10, 11-25, and over 25 frequencies) (χ 2 = 14.534, P = 0.002). The frequencies of CIK cells adoptive immunotherapy were significantly related with the decreasing risk of death in gastric cancer patients after adjustment for sex and age of the patients, tumor stage and relapse (HR = 0.54, 95% CI: 0.36-0.80) when the first stage Cox model was used to define the subjects who remained alive beyond 36 mo as survivors. However, no correlation was observed between the frequencies of death in CIK cells adoptive immunotherapy and the risk of gastric cancer patients (HR = 1.09, 95% CI: 0.63-0.89) when the second stage Cox model was used to define the subjects who survived for more than 36 mo as survivors. CONCLUSION: The survival time of the gastric cancer patients treated with chemotherapy combined with CIK cells adoptive immunotherapy is significantly longer than that of the patients treated with chemotherapy alone and increasing the frequency of CIK cells adoptive immunotherapy seems to benefit patients more.Jing-Ting Jiang, Chang-Ping Wu, Lu-Jun Chen, Xiao Zheng, Department of Tumor Biological Treatment, Third Affiliated Hospital of Soochow University, Changzhou 213003, Jiangsu Province, China Yi-Bei Zhu, Jing Sun, Xue-Guang Zhang, Key Laboratory of Stem Cell of Jiangsu Province, Institute of Biotechnology, Key Laboratory of Clinical Immunology of Jiangsu Province, Soochow University, Suzhou 215123, Jiangsu Province, China Yue-Ping Shen, Wen-Xiang Wei, Department of Medicine, Soochow University, Suzhou 215123, Jiangsu Province, China Bin-Feng Lu, Department of Immunology, University of Pitts- burgh School of Medicine, Pittsburgh, PA 15261, United States 2010World Journal of Gastroenterology2010,16,48:82
2Liver cancer incidence and mortality in China: Temporal trends and projections to 2030显示文摘Objective: Liver cancer is one of the most common cancers and major cause of cancer deaths in China,which accounts for over 50% of new cases and deaths worldwide.The systematic liver cancer statistics including of projection through 2030 could provide valuable information for prevention and control strategies in China,and experience for other countries.Methods: The burden of liver cancer in China in 2014 was estimated using 339 cancer registries' data selected from Chinese National Cancer Center(NCC).Incident cases of 22 cancer registries were applied for temporal trends from 2000 to 2014.The burden of liver cancer through 2030 was projected using age-period-cohort model.Results: About 364,800 new cases of liver cancer(268,900 males and 95,900 females) occurred in China,and about 318,800 liver cancer deaths(233,500 males and 85,300 females) in 2014.Western regions of China had the highest incidence and mortality rates.Incidence and mortality rates decreased by about 2.3% and 2.6% per year during the period of 2000-2014,respectively,and would decrease by more than 44% between 2014 and 2030 in China.The young generation,particularly for those aged under 40 years,showed a faster down trend.Conclusions: Based on the analysis,incidence and mortality rates of liver cancer are expected to decrease through 2030,but the burden of liver cancer is still serious in China,especially in rural and western areas.Most cases of liver cancer in China can be prevented through vaccination and more prevention efforts should be focused on high risk groups.Rongshou Zheng Chunfeng Qu Siwei Zhang Hongmei Zeng Kexin Sun Xiuying Gu Changfa Xia Zhixun Yang He Li Wenqiang Wei Wanqing Chen Jie He 2018Chinese Journal of Cancer Research2018,30,6:132

4Inhibition of SARS-CoV-2 (previously 2019-nCoV) infection by a highly potent pan-coronavirus fusion inhibitor targeting its spike protein that harbors a high capacity to mediate membrane fusion显示文摘The recent outbreak of coronavirus disease(COVID-19)caused by SARS-CoV-2 infection in Wuhan,China has posed a serious threat to global public health.To develop specific anti-coronavirus therapeutics and prophylactics,the molecular mechanism that underlies viral infection must first be defined.Therefore,we herein established a SARS-CoV-2 spike(S)protein-mediated cell-cell fusion assay and found that SARS-CoV-2 showed a superior plasma membrane fusion capacity compared to that of SARS-CoV.We solved the X-ray crystal structure of six-helical bundle(6-HB)core of the HR1 and HR2 domains in the SARS-CoV-2 S protein S2 subunit revealing that several mutated amino acid residues in the HR1 domain may be associated with enhanced interactions with the HR2 domain.We previously developed a pan-coronavirus fusion inhibitor,EK1,which targeted the HR!domain and could inhibit infection by divergent human coronaviruses tested,including SARS-CoV and MERS-CoV.Here we generated a series of lipopeptides derived from EK1 and found that EK1C4 was the most potent fusion inhibitor against SARS-CoV-2 S protein-mediated membrane fusion and pseudovirus infection with IC50s of 1.3 and 15.8 nM,about 241-and 149-fold more potent than the original EK1 peptide,respectively.EK1C4 was also highly effective against membrane fusion and infection of other human coronavirus pseudoviruses tested,including SARS-CoV and MERS-CoV,as well as SARSr-CoVs,and potently inhibited the replication of 5 live human coronaviruses examined,including SARS-CoV-2.Intranasal application of EK1C4 before or after challenge with HCoV-OC43 protected mice from infection,suggesting that EK1C4 could be used for prevention and treatment of infection by the currently circulating SARS-CoV-2 and other emerging SARSr-CoVs.Shuai Xia Meiqin Liu Chao Wang Wei Xu Qiaoshuai Lan Siliang Feng Feifei Qi Linlin Bao Lanying Du Shuwen Liu Chuan Qin Fei Sun Zhengli Shi Yun Zhu Shibo Jiang Lu Lu 2020Cell Research2020,30,4:81
5A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections.

11Identification and genetic mapping of four novel genes that regulate leaf development in Arabidopsis显示文摘Molecular and genetic characterizations of mutants have led to a better understanding of many developmental processes in the model system Arabidopsis thaliana. However, the leaf development that is specific to plants has been little studied. With the aim of contributing to the genetic dissection of leaf development, we have performed a large-scare screening for mutants with abnormal leaves. Among a great number of leaf mutants we have generated by T-DNA and transposon tagging and ethylmethae sulfonate (EMS) mutagenesis, four independent mutant lines have been identified and studied genetically. Phenotypes of these mutant lines represent the defects of four novel nuclear genes designated LL1 (LOTUS LEAF 1), LL2 (LOTUS LEAF 2), URO (UPRIGHT ROSETTE), and EIL (ENVIRONT CONDITION INDUCED LESION). The phenotypic analysis indicates that these genes play important roles during leaf development. FOr the further genetic analysis of these genes and the map-based cloning of LL1 and LL2, we have mapped these genes to chromosome regions with an efficient and rapid mapping method.SUN YUE WEI ZHANG FENG LING LI YING LI GUO TIAN LEI LIU HAI HUANG 2000Cell Research2000,10,4:53

13Breast 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
14Global 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
15“Volume-Point” heat conduction constructal optimization with entransy dissipation minimization objective based on rectangular element显示文摘By taking equivalent thermal resistance, which reflects the average heat conduc- tion effect and is defined based on entransy dissipation, as optimization objective, the 'volume to point' constructal problem of how to discharge the heat generated in a fixed volume to a heat sink on the border through relatively high conductive link is re-analyzed and re-optimized in this paper. The constructal shape of the control volume with the best average heat conduction effect is deduced. For the elemental area and the first order construct assembly, when the thermal current density in the high conductive link is linear with the length, the optimized shapes of assemble based on the minimization of entransy dissipation are the same as those based on minimization of maximum temperature difference, and the mean tem- perature difference is 2/3 of the maximum temperature difference. For the second and higher order construct assemblies, the thermal current densities in the high conductive link are not linear with the length, and the optimized shapes of assem- ble based on the minimization of entransy dissipation are different from those based on minimization of maximum temperature difference. For the same parame- ters, the constructs based on minimization of entransy dissipation and the con- structs based on minimization of maximum temperature difference are compared, and the results show that the constructs based on entransy dissipation can de- crease the mean temperature difference better than the constructs based on mini- mization of maximum temperature difference. But with the increase of the number of the order, the mean temperature difference does not always decrease, and there exist some fluctuations. Because the idea of entransy describes the heat transfer ability more suitably, all of the heat conduction constructal problems may be re-optimized based on it.WEI ShuHuan, CHEN LinGen & SUN FengRui Postgraduate School, Naval University of Engineering, Wuhan 430033, China 2008Science China(Technological Sciences)2008,51,8:47

18Pancreatic microcirculatory impairment in experimental acute pancreatitis in rats显示文摘AIM: To study the feature of pancreatic microcirculatoryimpairment, especially the initial changes, in caerulein-induced experimental acute pancreatitis (AP).METHODS: The pancreatic microcirculation of caerulein-induced AP model was studied by intravital fluorescencemicroscopy with FITC-labeled erythrocytes (FITC-RBC),scanning electron microscopy of vascular corrosion casts,and light microscopy of Chinese ink-injected/cleared tissues.RESULTS: Animals in caerulein-treated group showedhyperamylemia (× 2), pancreatic oedema, infiltration ofinflammatory cells in pancreas. Constrictions of intralobulararteriolar sphincters, presence of vacuoles in all layers ofsphincter, and gross irregularity in capillary network of aciniwere found in the AP specimens. The decrease of pancreaticcapillary blood flow (0.34±0.10 nl @ min-1 vs0.910.06 nl @rain-1 of control, P<0.001), reduction of functional capillarydensity(277± 13 cm-1 vs349±8 cm-1 of control, P<0.001),and irregular intermittent perfusion were observed incaerulein-induced groups.CONCLUSION: Impairment and constriction of pancreaticintralobular arteriolar sphincter are the initial microcirculatorylesions in the early phase of acute pancreatitis, and play akey role in the pancreatic ischaemia and pancreaticmicrovascular failure in acute pancreatitis.Zong-Guang Zhou You-Dai Chen Wei Sun Zhong Chen,Ⅲ Department of General Surgery(Gastroenteric Surgery),West China Hospital,Sichuan University,Chengdu 610041,Sichuan,China 2002World Journal of Gastroenterology2002,8,5:49
19Electroacupuncture improves learning and memory functions in a rat cerebral ischemia/reperfusion injury model through PI3K/Akt signaling pathway activation显示文摘Electroacupuncture has been widely used to treat cognitive impairment after cerebral ischemia,but the underlying mechanism has not yet been fully elucidated.Studies have shown that autophagy plays an important role in the formation and development of cognitive impairment,and the phosphoinositide 3-kinase(PI3K)/Akt signaling pathway plays an important role in autophagy regulation.To investigate the role played by the PI3K/Akt signaling pathway in the electroacupuncture treatment of cerebral ischemia/reperfusion rat models,we first established a rat model of cerebral ischemia/reperfusion through the occlusion of the middle cerebral artery using the suture method.Starting at 2 hours after modeling,electroacupuncture was delivered at the Shenting(GV24)and Baihui(GV20)acupoints,with a dilatational wave(1-20 Hz frequency,2 mA intensity,6 V peak voltage),for 30 minutes/day over 8 consecutive days.Our results showed that electroacupuncture reduced the infarct volume in a rat model of cerebral ischemia/reperfusion injury,increased the mRNA expression levels of the PI3K/Akt signaling pathwayrelated factors Beclin-1,mammalian target of rapamycin(mTOR),and PI3K,increased the protein expression levels of phosphorylated Akt,Beclin-1,PI3K,and mTOR in the ischemic cerebral cortex,and simultaneously reduced p53 mRNA and protein expression levels.In the Morris water maze test,the latency to find the hidden platform was significantly shortened among rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation.In the spatial probe test,the number of times that a rat crossed the target quadrant was increased in rats subjected to electroacupuncture stimulation compared with rats without electroacupuncture stimulation.Electroacupuncture stimulation applied to the Shenting(GV24)and Baihui(GV20)acupoints activated the PI3K/Akt signaling pathway and improved rat learning and memory impairment.This study was approved by the Animal Ethics Committee of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine,China(approval No.8150150901)on March 10,2016.Hui-Ling Wang Fei-Lai Liu Rui-Qing Li Ming-Yue Wan Jie-Ying Li Jing Shi Ming-Li Wu Jun-Hua Chen Wei-Juan Sun Hong-Xia Feng Wei Zhao Jin Huang Ren-Chao Liu Wen-Xue Hao Xiao-Dong Feng 2021Neural Regeneration Research2021,16,6:48
20Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control.Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu 2021Science China(Life Sciences)2021,64,5:46
