1First observation of tropospheric nitrogen dioxide from the Environmental Trace Gases Monitoring Instrument onboard the GaoFen-5 satellite显示文摘The Environmental Trace Gases Monitoring Instrument(EMI)is the first Chinese satellite-borne UV–Vis spectrometer aiming to measure the distribution of atmospheric trace gases on a global scale.The EMI instrument onboard the GaoFen-5 satellite was launched on 9 May 2018.In this paper,we present the tropospheric nitrogen dioxide(NO2)vertical column density(VCD)retrieval algorithm dedicated to EMI measurement.We report the first successful retrieval of tropospheric NO_(2) VCD from the EMI instrument.Our retrieval improved the original EMI NO_(2) prototype algorithm by modifying the settings of the spectral fit and air mass factor calculations to account for the on-orbit instrumental performance changes.The retrieved EMI NO_(2) VCDs generally show good spatiotemporal agreement with the satellite-borne Ozone Monitoring Instrument and TROPOspheric Monitoring Instrument(correlation coefficient R of ~0.9,bias<50%).A comparison with ground-based MAX-DOAS(Multi-Axis Differential Optical Absorption Spectroscopy)observations also shows good correlation with an R of 0.82.The results indicate that the EMI NO_(2) retrieval algorithm derives reliable and precise results,and this algorithm can feasibly produce stable operational products that can contribute to global air pollution monitoring.Chengxin Zhang Cheng Liu Ka Lok Chan Qihou Hu Haoran Liu Bo Li Chengzhi Xing Wei Tan Haijin Zhou Fuqi Si Jianguo Liu 2020Light(Science & Applications)2020,9,1:11
2Emerging role of Hippo pathway in gastric and othergastrointestinal cancers显示文摘More evidence has underscored the importance of Hippo signaling pathway in gastrointestinal tissue homeostasis, whereas its deregulation induces tumorigenesis. Yes-associated protein 1(YAP1) and its close paralog TAZ, transcriptional co-activator with a PDZbinding motif, function as key effectors negatively controlled by the Hippo pathway. YAP1/TAZ exerts oncogenic activities by transcriptional regulation via physical interaction with TEAD transcription factors. In various cancers, Hippo pathway cross-talks with pro- or anti-tumorigenic pathways such as GPCR, Wnt/β-catenin, Notch and TGF-β signaling and is deregulated by multiple factors including cell density/junction and micro RNAs. As YAP1 expression is significantly associated with poor prognosis of gastric and other gastrointestinal cancers, detailed delineation of Hippo regulation in tumorigenesis provides novel insight for therapeutic intervention. In current review, we summarized the recent research progresses on the deregulation of Hippo pathway in the gastrointestinal tract including stomach and discuss the molecular consequences leading to tumorigenesis.Wei Kang Alfred SL Cheng Jun Yu Ka Fai To 2016World Journal of Gastroenterology2016,22,3:11
3Temporal Variations of the Frontal and Monsoon Storm Rainfall during the First Rainy Season in South China显示文摘The temporal variations in storm rainfall during the first rainy season (FRS) in South China (SC) are investigated in this study. The results show that the inter-annual variations in storm rainfall during the FRS in SC seem to be mainly influenced by the frequency of storm rainfall, while both frequency and intensity affect the inter-decadal variations in the total storm rainfall. Using the definitions for the beginning and ending dates of the FRS, and the onset dates of the summer monsoon in SC, the FRS is further divided into two sub-periods, i.e., the frontal and monsoon rainfall periods. The inter-annual and inter-decadal variations in storm rainfall during these two periods are investigated here. The results reveal a significant out-of-phase correlation between the frontal and monsoon storm rainfall, especially on the inter-decadal timescale, the physical mechanism for which requires further investigation.YUAN Fang WEI Ke CHEN Wen FONG Soi Kun LEONG Ka Cheng 2010Atmospheric and Oceanic Science Letters2010,3,5:10
4Does the Belt and Road Initiative Promote Bilateral Political Relations?显示文摘This paper examines the role of the Belt and Road Initiative (BRI) in enhancing political relations between China and its partner countries. We postulate that an international economic cooperation scheme such as the BRI may facilitate commercial exchanges and increase the participating countries’ economic gains. This should generate incentives for these countries to avoid political tensions that may jeopardize mutually beneficial economic exchanges, and to expand the constellation of domestic coalitions in support of cordial diplomatic and political relations. We test the effect of the BRI on bilateral political relations using data on political relations between China and 91 countries along the BRI route between 2006 and 2018. Treating the promulgation of the BRI in 2013 as a policy shock, our difference-in-difference analysis lends substantial support to our hypotheses. Further analyses of the underlying causal mechanisms suggest that the BRI bolsters political relations by strengthening economic ties with partner countries through trade and investment related to economic cooperation.Yue Lu Wei Gu Ka Zeng 2021China & World Economy2021,29,5:8
5Oral microbiome and pancreatic cancer显示文摘BACKGROUND Microbiota profiles differ between patients with pancreatic cancer and healthy people,and understanding these differences may help in early detection of pancreatic cancer.Saliva sampling is an easy and cost-effective way to determine microbiota profiles compared to fecal and tissue sample collection.AIM To investigate the saliva microbiome distribution in patients with pancreatic adenocarcinoma(PDAC)and the role of oral microbiota profiles in detection and risk prediction of pancreatic cancer.METHODS We conducted a prospective study of patients with pancreatic cancer(n=41)and healthy individuals(n=69).Bacterial taxa were identified by 16S ribosomal ribonucleic acid gene sequencing,and a linear discriminant analysis effect size algorithm was used to identify differences in taxa.Operational taxonomic unit values of all selected taxa were converted into a normalized Z-score,and logistic regressions were used to calculate risk prediction of pancreatic cancer.RESULTS Compared with the healthy control group,carriage of Streptococcus and Leptotrichina(z-score)was associated with a higher risk of PDAC[odds ratio(OR)=5.344,95%confidence interval(CI):1.282-22.282,P=0.021 and OR=6.886,95%CI:1.423-33.337,P=0.016,respectively].Veillonella and Neisseria(z-score)were considered a protective microbe that decreased the risk of PDAC(OR=0.187,95%CI:0.055-0.631,P=0.007 and OR=0.309,95%CI:0.100-0.952,P=0.041,respectively).Among the patients with PDAC,patients reporting bloating have a higher abundance of Porphyromonas(P=0.039),Fusobacterium(P=0.024),and Alloprevotella(P=0.041);while patients reporting jaundice had a higher amount of Prevotella(P=0.008);patients reporting dark brown urine had a higher amount of Veillonella(P=0.035).Patients reporting diarrhea had a lower amount of Neisseria and Campylobacter(P=0.024 and P=0.034),and patients reporting vomiting had decreased Alloprevotella(P=0.036).CONCLUSION Saliva microbiome was able to distinguish patients with pancreatic cancer and healthy individuals.Leptotrichia may be specific for patients living in Sichuan Province,southwest China.Symptomatic patients had different bacteria profiles than asymptomatic patients.Combined symptom and microbiome evaluation may help in the early detection of pancreatic cancer.Ai-Lin Wei Mao Li Guo-Qing Li Xuan Wang Wei-Ming Hu Zhen-Lu Li Jue Yuan Hong-Ying Liu Li-Li Zhou Ka Li Ang Li Mei Rosemary Fu 2020World Journal of Gastroenterology2020,26,48:4

7A murine model for human immune thrombocytopenic purpura and comparative analysis of multiple gene expression in bone marrow and spleen显示文摘Homeostasis of platelet number in human and other mammals is well maintained for prevention of minor bleeding and for other immunological functions,but the exact molecular mechanism responsible for immune thrombocytopenic purpura(ITP) has not been fully understood.In an effort to identify genetic factors involved in initiation of platelet production in response to bleeding injury or platelet destruction,we have successfully generated an animal model of human ITP via intraperitoneal injection of anti-platelet antibody into the Balb/c mouse.Platelet counts were dropped dramatically in animals that received antibody injection within 4 h,maintained at the mini-mum level for a period of 44 h,started to rebound after 48 h,and reached to the maximum at 144 h(6 days).Final homeostasis reached at approximately 408 h(17 days),following a minor cycle of platelet number fluctuation.Using semi-quantitative RT-PCR,we assessed and compared mRNA level of CD41,c-myb,c-mpl,caspase-3,caspase-9,GATA-1,and Bcl-xl in bone marrow and spleen.Alteration of mRNA expression was correlated with the change of platelet level,and an inverse relationship was found for expression of the genes between bone marrow and spleen.No transcription was detectable for any of the seven genes in bone marrow at the time when platelet number reached the maximum(144 h).In contrast,mRNA transcripts of the seven genes were found to be at the highest level in spleen tissue.This is the first study of simultaneous detection of multiple platelet related genes in a highly reproducible ITP animal model.Our results provided the supportive evidence that expression of the above seven genes are more related to negative regulation of platelet number in spleen tissue,at least in the model animals.Hong Wei Xinchun Ding Jiangong Ren Ka Liu Pingping Tan Daquan Li Runlin Z.
