3Crustal P-wave velocity structure of the Longmenshan region and its tectonic implications for the 2008 Wenchuan earthquake显示文摘The P-wave velocity structure of the crust in the Longmenshan region has been imaged by seismic travel time tomography us ing local and regional first P-wave arrivals recorded from 2000 to 2008. The tomographic model provides a way to analyze the deep tectonics of the Longmenshan fault belt and the tectonic implications for the 2008 Ms8.0 Wenchuan earthquake. The P-wave velocity images indicate that the initial rupture site and focal depth of the Wenchuan earthquake, together with the di rection of rupture propagation, closely relate to the crustal structure of the Longmenshan region. The Pengguan massif to the west of the Longmenshan fault belt is characterized by high velocity anomalies, suggesting that the crust has a strong strain strength that can accumulate large stresses over a long period. The Ms8.0 Wenchuan earthquake is located at the southwestern end of the Pengguan massif and the western edge of the Sichuan Basin. The collision between the Pengguan massif and the Sichuan Basin becomes the primary reason for the occurrence of the Ms8.0 Wenchuan earthquake. To the north of Wenchuan, the occurrence and propagation of rupture benefit from low velocity anomalies along the Longmenshan fault belt; whereas to the south of Wenchuan, the brittle rupture can occur with more difficulty in relatively weak crust with low velocities. This may be one of the reasons for the absence of aftershocks to the south of Wenchuan, and the rupture induced by the Ms8.0 Wenchuan earthquake propagating from the north to the south along the Longmenshan fault belt. The deep geodynamics of the Ms8.0 Wenchuan earthquake may occur due to the discrepancy of crustal structures on the two sides of the Longmenshan fault belt. Ductile deformation and crustal flow can easily occur in the weak middle-lower crust beneath the Songpan-Garze orogenic belt. The eastward movement of the Tibetan Plateau is obstructed by the rigid lithosphere of the Sichuan Basin, and then the thick ening of the middle-lower crust and vertical deformation occur in the crust of the Longmenshan fault belt. In addition, the down-warping of the Moho and the basement thrusting onto the range front induced crustal deformation and strain accumula tion, which provided the potential energy to trigger the occurrence of the Ms8.0 Wenchuan earthquake.LI ZhaWei XU Yi HUANG RunQiu HAO TianYao XU Ya LIU JingSong LIU JianHua 2011Science China Earth Sciences2011,54,9:23
4Transcription analysis of peloric mutants of Phalaenopsis orchids derived from tissue culture显示文摘Tissue culture has been widely used for mass propagation of Phalaenopsis. However, somaclonal variation occurred during micropropagation process posed a severe problem by affecting product quality. In this study, wild type and peloric flower buds of Phalaenopsis hybrids derived from flower stalk nodal culture were used for cDNA-RAPD and cDNA suppression subtractive hybridization analyses in order to study their genetic difference in terms of expressed sequence tags. A total of 209 ESTs from normal flower buds and 230 from mutants were sequenced. These ESTs sequences can be grouped into several functional categories involved in different cellular processes including metabolism, signal transduction, transcription, cell growth and division, protein synthesis, and protein localization, and into a subcat- egory of proteins with unknown function. Cymbidium mosaic virus transcript was surprisingly found expressed fre- quently in the peloric mutant of P. Little Mary. Real-time RT-PCR analysis on selected ESTs showed that in mutant flower buds, a bZIP transcription factor (TGA1a-like protein) was down-regulated, while up-regulated genes include auxin-regulated protein kinase, cyclophilin, and TCP-like genes. A retroelement clone was also preferentially expressed in the peloric mutant flowers. On the other hand, ESTs involved in DNA methylation, chromatin remodeling and post- transcriptional regulation, such as DNA methyltransferase, histone acetyltransferase, ERECTA, and DEAD/DEAH RNA helicase, were enriched in normal flower buds than the mutants. The enriched transcripts in the wild type indicate the down regulation of these transcripts in the mutants, and vice versa. The potential roles of the analyzed transcripts in the development of Phalaenopsis flowers are discussed.Ya Huei CHEN Yi Jung TSAI Jian Zhi HUANG Fure Chyi CHEN 2005Cell Research2005,15,8:21
5The Role of Fibrocyte in the Pathogenesis of Silicosis显示文摘Exposure to free silica induces silicosis and myofibroblasts are regarded as primary effector cells.Fibrocytes can differentiate into myofibroblast.Therefore,the present study was designed to investigate whetherLI Juan YAO Wu HOU Jian Yong ZHANG Lin BAO Lei CHEN Hui Ting WANG Di YUE Zhong Zheng LI Yi Ping ZHANG Miao YU Xing Hao ZHANG Jian Hui QU Ya Qian HAO Chang Fu 2018Biomedical and Environmental Sciences2018,31,4:20

8Evaluating the Nutritional Status of Oncology Patients and Its Association with Quality of Life显示文摘Objective The primary aim of the study was to compare two nutritional status evaluation tools: the Patient-Generated Subjective Global Assessment(PG-SGA) and Nutritional Risk Screening(NRS-2002). Using the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire 30(EORTC QLQ-C30), the second aim was to provide constructive advice regarding the quality of life of patients with malignancy. Methods This study enrolled 312 oncology patients and assessed their nutritional status and quality of life using the PG-SGA, NRS-2002, and EORTC QLQ-C30. Results The data indicate that 6% of the cancer patients were well nourished. The SGA-A had a higher sensitivity(93.73%) but a poorer specificity(2.30%) than the NRS-2002(69.30% and 25.00%, respectively) after comparison with albumin. There was a low negative correlation and a high similarity between the PG-SGA and NRS-2002 for evaluating nutritional status, and there was a significant difference in the median PG-SGA scores for each of the SGA classifications(P < 0.001). The SGA-C group showed the highest PG-SGA scores and lowest body mass index. The majority of the target population received 2 points for each item in our 11-item questionnaire from the EORTC QLQ-C30. Conclusion The data indicate that the PG-SGA is more useful and suitable for evaluating nutritional status than the NRS-2002. Additionally, early nutrition monitoring can prevent malnutrition and improve the quality of life of cancer patients.ZHANG Ya Hui XIE Fang Yi CHEN Ya Wen WANG Hai Xia TIAN Wen Xia SUN Wen Guang WU Jing 2018Biomedical and Environmental Sciences2018,31,9:14
9Late Pleistocene glaciation of the Hulifang Massif of Gongwang mountains in Yunnan Province显示文摘Late Pleistocene glaciation was restricted to only a few high mountains in eastern China. The Gongwang mountainsconstitute one ofthe typicalplacesonce glaciated.Geomorphic mapping of the area and the TL dating provides evidence for at least four distinct glaciations. YJT-I glacial advance occurred about100 ka BP and two TL absolute ages(101,100 ±7780 a BP;104,000±8300 a BP)indicate thisadvance happened during the Penultimale Glaciation.The early stage glacialadvance (YJT-II advance) during the last glaciation occurred about 40,920±3400 a BP. The last glacial maximum advance (YJT-IIIadvance)about18-25 ka BP,which sustained by two TL ages(18,230 ± 1420 a BP;25,420 ±2110 a BP).The Penultimale and the early stage glaciationswere more extensive and the lastglacialmaximum (LGM )and the late-glacialperiod (YJT-IV advance,10 ka BP) were progressively less extensive. Correlated with the other mountains in eastern China, these glacial advances in the Gongwang mountains justlike the advances in the western partsuch as Diancang mountains,Yulong mountains ofYunnan Province and the glacierseries are more complete than the adjacent mid-latitude regions such as Taibai mountain and Taiwan mountains and are roughly representativeofclimatechangesduring thelastglacialcyclein Yunnan Province.ZHANG Wei CUI Zhijiu FENG Jinliag YI Chaolu YA NG Jianqiang 2005Journal of Geographical Sciences2005,15,4:13
10Serum levels of mi RNA in patients with hepatitis B virus-associated acute-on-chronic liver failure显示文摘Background: Hepatitis B virus(HBV)-associated acute-on-chronic liver failure(HBV-ACLF) is a lifethreatening condition and its exact pathophysiology and progression remain unclear. The present study aimed to assess the role of serum mi RNAs in the evaluation of HBV-ACLF and to develop a model to predict the outcomes for ACLF.Methods: Serum was collected from 41 chronic hepatitis B and 55 HBV-ACLF patients in addition to30 chronic asymptomatic HBV carriers as controls. The mi RNAs expressions were measured by real-time quantitative PCR(q-PCR). Statistical analyses were conducted to assess the ability of differentially expressed mi RNAs and other prognostic factors in identifying ACLF prognosis and to develop a new predictive model.Results: Real-time q-PCR indicated that serum miR-146 a-5 p, mi R-122-3 p and mi R-328-3 p levels were significantly upregulated in ACLF patients compared to chronic hepatitis B and chronic asymptomatic HBV carriers patients. In addition, multivariate regression analyses indicated that Na+, INR, gastrointestinal bleeding and mi R-122-3 p are all independent factors that are reliable and sensitive to the prognosis of HBV-ACLF. Therefore, we developed a new model for the prediction of HBV-ACLF disease state: Y = 0.402 × Na+-1.72 × INR-4.963 × gastrointestinal bleeding(Yes = 0; No = 1)-0.278 ×(mi R-122-3 p) + 50.449. The predictive accuracy of the model was 95.3% and the area under the receiver operating characteristic curve(AUROC) was 0.847.Conclusions: Expression levels of these mi RNAs(miR-146 a-5 p, mi R-122-3 p and mi R-328-3 p) positively correlate with the severity of liver inflammation in patients with ACLF and may be useful to predict HBV-ACLF severity.Ya Wen Shi-Fang Peng Lei Fu Xiao-Yu Fu Da-Xian Wu Bing-Jie Liu De-Ming Tan Yi Ouyang 2018Hepatobiliary & Pancreatic Diseases International2018,17,2:13

14Cadmium Activates Reactive Oxygen Species-dependent AKT/mT OR and Mitochondrial Apoptotic Pathways in Neuronal Cells显示文摘Objective To examine the role of Cd-induced reactive oxygen species(ROS)generation in the apoptosis of neuronal cells.Methods Neuronal cells(primary rat cerebral cortical neurons and PC12 cells)were incubated with or without Cd post-pretreatment with rapamycin(Rap)or N-acetyl-L-cysteine(NAC).Cell viability was determined by MTT assay,apoptosis was examined using flow cytometry and fluorescence microscopy,and the activation of phosphoinositide 3'-kinase/protein kinase B(Akt)/mammalian target of rapamycin(m TOR)and mitochondrial apoptotic pathways were measured by western blotting or immunofluorescence assays.Results Cd-induced activation of Akt/m TOR signaling,including Akt,m TOR,p70 S6 kinase(p70 S6K),and eukaryotic initiation factor 4E binding protein 1(4E-BP1).Rap,an m TOR inhibitor and NAC,a ROS scavenger,blocked Cd-induced activation of Akt/m TOR signaling and apoptosis of neuronal cells.Furthermore,NAC blocked the decrease of B-cell lymphoma 2/Bcl-2 associated X protein(Bcl-2/Bax)ratio,release of cytochrome c,cleavage of caspase-3 and poly(ADP-ribose)polymerase(PARP),and nuclear translocation of apoptosis-inducing factor(AIF)and endonuclease G(Endo G).Conclusion Cd-induced ROS generation activates Akt/m TOR and mitochondrial pathways,leading to apoptosis of neuronal cells.Our findings suggest that m TOR inhibitors or antioxidants have potential for preventing Cd-induced neurodegenerative diseases.YUAN Yan WANG Yi HU Fei Fei JIANG Chen Yang ZHANG Ya Jing YANG Jin Long ZHAO Shi Wen GU Jian Hong LIU Xue Zhong BIAN Jian Chun LIU Zong Ping 2016Biomedical and Environmental Sciences2016,29,2:8
15Association of Overlapped and Un-overlapped Comorbidities with COVID-19 Severity and Treatment Outcomes: A Retrospective Cohort Study from Nine Provinces in China显示文摘Objective Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.Methods A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients’ medical records. Multivariable logistic regression models were used to estimate the odds ratio(OR) and 95% confidence interval(95% CI) of the associations between comorbidities(cardiometabolic or non-cardiometabolic diseases), clinical severity, and treatment outcomes of COVID-19.Results Overall, 158(13.6%) patients were diagnosed with severe illness and 32(2.7%) had unfavorable outcomes. Hypertension(2.87, 1.30–6.32), type 2 diabetes(T2 DM)(3.57, 2.32–5.49),cardiovascular disease(CVD)(3.78, 1.81–7.89), fatty liver disease(7.53, 1.96–28.96), hyperlipidemia(2.15, 1.26–3.67), other lung diseases(6.00, 3.01–11.96), and electrolyte imbalance(10.40, 3.00–26.10)were independently linked to increased odds of being severely ill. T2 DM(6.07, 2.89–12.75), CVD(8.47,6.03–11.89), and electrolyte imbalance(19.44, 11.47–32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission(5.46,3.25–9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes(6.58, 1.46–29.64) within two weeks.Conclusion Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.MA Yan ZHU Dong Shan CHEN Ren Bo SHI Nan Nan LIU Si Hong FAN Yi Pin WU Gui Hui YANG Pu Ye BAI Jiang Feng CHEN Hong CHEN Li Ying FENG Qiao GUO Tuan Mao HOU Yong HU Gui Fen HU Xiao Mei HU Yun Hong HUANG Jin HUANG Qiu Hua HUANG Shao Zhen JI Liang JIN Hai Hao LEI Xiao LI Chun Yan LI Min Qing LI Qun Tang LI Xian Yong LIU Hong De LIU Jin Ping LIU Zhang MA Yu Ting MAO Ya MO Liu Fen NA Hui WANG Jing Wei SONG Fang Li SUN Sheng WANG Dong Ting WANG Ming Xuan WANG Xiao Yan WANG Yin Zhen WANG Yu Dong WU Wei WU Lan Ping XIAO Yan Hua XIE Hai Jun XU Hong Ming XU Shou Fang XUE Rui Xia YANG Chun YANG Kai Jun YUAN Sheng Li ZHANG Gong Qi ZHANG Jin Bo ZHANG Lin Song ZHAO Shu Sen ZHAO Wan Ying ZHENG Kai ZHOU Ying Chun ZHU Jun Teng ZHU Tian Qing ZHANG Hua Min WANG Yan Ping WANG Yong Yan 2020Biomedical and Environmental Sciences2020,33,12:8

18DEK43 is a P-type pentatricopeptide repeat(PPR)protein responsible for the Cis-splicing of nad4 in maize mitochondria显示文摘Mitochondria, the main energy transducers in plant cells, require the proper assembly of respiratory chain complexes Ⅰ–Ⅴ for their function. The NADH dehydrogenase4(nad4) gene encodes mitochondrial respiratory chain complex Ⅰ subunit Ⅳ, but the mechanism underlying nad4 transcript splicing is unclear. Here, we report that the P-type pentatricopeptide repeat(PPR) protein DEFECTIVE KERNEL 43(DEK43) is responsible for cis-splicing of the nad4 transcript in maize. We demonstrate that DEK43 localizes to both the nucleus and mitochondria. The mutation of Dek43 resulted in embryo-lethal and light-colored defective kernels. Among the 22 mitochondrial group Ⅱ introns, the splicing efficiency of nad4 introns 1 and 3 was reduced by up to 50% compared to the wild type. The levels of complex Ⅰ and supercomplex Ⅰ+Ⅲ2 were also reduced in dek43. Furthermore, in-gel NADH dehydrogenase assays indicated that the activities of these complexes were significantly reduced in dek43. Further, the mitochondrial ultrastructure was altered in the mutant. Together, our findings indicate that DEK43, a dual-localized PPR protein,plays an important role in maintaining mitochondrial function and maize kernel development.Ru Chang Ren Li Li Wang Lin Zhang Ya Jie Zhao Jia Wen Wu Yi Ming Wei Xian Sheng Zhang Xiang Yu Zhao 2020Journal of Integrative Plant Biology2020,62,3:6
19Kiwifruit Genome Database(KGD):a comprehensive resource for kiwifruit genomics显示文摘Kiwifruit(Actinidia spp.)plants produce economically important fruits containing abundant,balanced phytonutrients with extraordinarily high vitamin C contents.Since the release of the first kiwifruit reference genome sequence in 2013,large volumes of genome and transcriptome data have been rapidly accumulated for a handful of kiwifruit species.To efficiently store,analyze,integrate,and disseminate these large-scale datasets to the research community,we constructed the Kiwifruit Genome Database(KGD;http://kiwifruitgenome.org/).The database currently contains all publicly available genome and gene sequences,gene annotations,biochemical pathways,transcriptome profiles derived from public RNA-Seq datasets,and comparative genomic analysis results such as syntenic blocks and homologous gene pairs between different kiwifruit genome assemblies.A set of user-friendly query interfaces,analysis tools and visualization modules have been implemented in KGD to facilitate translational and applied research in kiwifruit,which include JBrowse,a popular genome browser,and the NCBI BLAST sequence search tool.Other notable tools developed within KGD include a genome synteny viewer and tools for differential gene expression analysis as well as gene ontology(GO)term and pathway enrichment analysis.Junyang Yue Jiacheng Liu Wei Tang Ya Qing Wu Xiaofeng Tang Wei Li Ying Yang Lihuan Wang Shengxiong Huang Congbing Fang Kun Zhao Zhangjun Fei Yongsheng Liu Yi Zheng 2020Horticulture Research2020,7,1:6
20V_p and V_p/V_s structures in the crust and upper mantle of the Taiwan region, China显示文摘A tomographic study of the Vp and Vp/Vs structures in the crust and upper mantle beneath the Taiwan region of China is conducted by simultaneous inversion of P and S arrival times. Compared with the previous tomographic results, the spherical finite difference technique is suitable for the strong heterogeneous velocity structure, and may improve the accuracy in the travel time and three-dimensional ray tracing calculations. The Vp and Vp/Vs structures derived from joint inversion and the relocated earthquakes can provide better constraints for analyzing the lateral heterogeneity and deep tectonic characters in the crust and upper mantle. Our tomographic results reveal significant relations between the seismic wavespeed structure and the tectonic characters. In the shallow depth, sedimentary basins and orogen show distinct wavespeed anomalies, with low Vp, high Vp/Vs in basins and high Vp, low Vp/Vs in orogen. As the suture zone of Eurasian Plate and Philippine Sea Plate, Longitudinal Valley is characterized by a significant high Vp/Vs anomaly extending to the middle-lower crust and upper mantle, which reflects the impact of rock cracking, partial melting, and the presence of fluids. In the northeast Taiwan, the Vp, Vp/Vs anomalies and relocated earthquakes depict the subducting Philippine Sea Plate under the Eurasian Plate. The high Vp of oceanic plate and the low Vp, high Vp/Vs atop the subducted oceanic plate extend to 80 km depth. Along the east-west profiles, the thickness of crust reaches 60 km at the east of Central Range with eastward dipping trend, which reveals the eastward subduction of the thickened and deformed crust of the Eurasian continental plate.LI ZhiWei XU Yi HAO TianYao XU Ya 2009Science China Earth Sciences2009,52,7:6
