1Cluster analysis for syndromes of real-world coronary heartdisease with angina pectoris显示文摘Syndromes of coronary heart disease with angina pectoris were analyzed to provide guidance forclinical practice and to improve accuracy of traditional Chinese medicine (TCM) diagnoses and efficacy of TCMtreatment. A total of 860 cases with coronary heart disease with angina pectoris were selected from TCM ClinicalResearch Information Sharing System for TCM clinics and research. Syndromes were automatically extractedwith the cluster method and were analyzed to provide objective evidence for clinical studies. Final syndromeclassifications were recognized and confirmed by clinical experts. Popular syndromes included Qi and blooddeficiency, blood stasis and obstruction collaterals, liver depression and spleen deficiency, and Qi stagnation andblood stasis. Syndromes Qi and blood deficiency and blood stasis and obstruction collaterals accounted for 28.61%of total syndromes, whereas liver depression and spleen deficiency and Qi stagnation and blood stasis accountedfor 26.44%. The main syndrome elements comprised Qi deficiency, blood deficiency, blood stasis, and Qistagnation.Yufeng Zhao Xueyun Yu Xinyu Cao Lin Luo Liyun He Shusong Mao Li Ma Peijing Rong Yuxue Zhao Guozheng Li Baoyan Liu 2018Frontiers of Medicine2018,12,5:28
2Processes of initial collision and suturing between India and Asia显示文摘The initial collision between Indian and Asian continents marked the starting point for transformation of land-sea thermal contrast,uplift of the Tibet-Himalaya orogen,and climate change in Asia.In this paper,we review the published literatures from the past 30 years in order to draw consensus on the processes of initial collision and suturing that took place between the Indian and Asian plates.Following a comparison of the different methods that have been used to constrain the initial timing of collision,we propose that the tectono-sedimentary response in the peripheral foreland basin provides the most sensitive index of this event,and that paleomagnetism presents independent evidence as an alternative,reliable,and quantitative research method.In contrast to previous studies that have suggested collision between India and Asia started in Pakistan between ca.55 Ma and50 Ma and progressively closed eastwards,more recent researches have indicated that this major event first occurred in the center of the Yarlung Tsangpo suture zone(YTSZ) between ca.65 Ma and 63 Ma and then spreading both eastwards and westwards.While continental collision is a complicated process,including the processes of deformation,sedimentation,metamorphism,and magmatism,different researchers have tended to define the nature of this event based on their own understanding,an intuitive bias that has meant that its initial timing has remained controversial for decades.Here,we recommend the use of reconstructions of each geological event within the orogenic evolution sequence as this will allow interpretation of collision timing on the basis of multidisciplinary methods.DING Lin Satybaev MAKSATBEK CAI FuLong WANG HouQi SONG PeiPing JI WeiQiang XU Qiang ZHANG LiYun Qasim MUHAMMAD Baral UPENDRA 2017Science China Earth Sciences2017,60,4:23
3Comparsion analysis of data mining models applied to clinical research in Traditional Chinese Medicine显示文摘OBJECTIVE: To help researchers selecting appropriate data mining models to provide better evidence for the clinical practice of Traditional Chinese Medicine(TCM) diagnosis and therapy.METHODS: Clinical issues based on data mining models were comprehensively summarized from four significant elements of the clinical studies:symptoms, symptom patterns, herbs, and efficacy.Existing problems were further generalized to determine the relevant factors of the performance of data mining models, e.g. data type, samples, parameters, variable labels. Combining these relevant factors, the TCM clinical data features were compared with regards to statistical characters and informatics properties. Data models were compared simultaneously from the view of applied conditions and suitable scopes.RESULTS: The main application problems were the inconsistent data type and the small samples for the used data mining models, which caused the inappropriate results, even the mistake results. These features, i.e. advantages, disadvantages, satisfied data types, tasks of data mining, and the TCM issues, were summarized and compared.CONCLUSION: By aiming at the special features of different data mining models, the clinical doctors could select the suitable data mining models to resolve the TCM problem.Yufeng Zhao Qi Xie Liyun He Baoyan Liu Kun Li Xiang Zhang Wenjing Bai Lin Luo Xianghong Jing Ruili Huo 2014Journal of Traditional Chinese Medicine2014,34,5:14
4Study on the photosynthetic performances of Enteromorpha prolifera collected from the surface and bottom of the sea of Qingdao sea area显示文摘In this work, the photosynthetic performances of Enteromorpha prolifera thalli collected from the sur- face and bottom of the sea of Qingdao sea area were studied with chlorophyll fluorescence and oxy- graph technology. The samples with the highest photosynthetic activity among their kinds, the floating thalli from the sea surface of the south of the Qingdao Olympic Sailing Center and the sedimentary thalli from the mud surface of the bottom Tuandao bay, were chosen as representatives of surface thalli and bottom thalli, respectively. The results showed that the maximal PSII quantum yield of the floating thalli was significantly lower than the normal level although their photosynthetic activities were relatively high; the photosynthetic potential of the thalli form the mud surface was extremely low. Thus, it is indicated that the floating thalli are seriously stressed by their environment and the thalli from the mud surface are already dead or are dying. On the other hand, the results of the laboratory cultivation showed that the sedimentary thalli cannot regain normal photosynthetic activity even under normal illumination condi- tions. Thus, the thalli from the mud surface cannot become reproductive source of the alga even if they can reach sea surface again. Therefore, a preliminary conclusion can be reached that, up to mid-July 2008, the environmental conditions of the Qingdao sea area are not suitable for the growth of the alga E. prolifera and for this reason the biomass of E. prolifera, in the area, could be declining.LIN APeng WANG Chao QIAO HongJin PAN GuangHua WANG GuangCe SONG LiYun WANG ZhiYuan SUN Song ZHOU BaiCheng 2009Chinese Science Bulletin2009,54,3:14

6Stable isotopes of modern herbivore tooth enamel in the Tibetan Plateau: Implications for paleoelevation reconstructions显示文摘Fossil tooth enamel from herbivores is considered one of the best proxies for paleoclimate and paleoelevation reconstructions, due to its low susceptibility to diagenetic alteration. A synthesis of oxygen and carbon isotope analyses of modern tooth enamel from herbivores such as Tibetan yaks, asses and antelopes is assessed. The average δ 13C(PDB) value of herbivore tooth enamel in the Lhasa and south Qiangtang terrains is-11.3‰± 1.1‰, whereas in the north Qiangtang and Hoh Xil terrains value is-10.2‰± 1.4‰ consistent with the current C3-dominant ecotype in the Tibetan Plateau. In addition, the average δ18O(PDB) values from tooth enamel show a northward systematic increase from-11.8‰± 3.4‰ in the Gyirong Basin, to-11.1‰± 1.1‰ in the Lhasa and southern Qiangtang terrains, and then to-9.0‰± 1.1‰ in the northern Qiangtang and the Hoh Xil areas, similar to those of the local river water and precipitation variation trends. It is suggested that δ 18O(PDB) values of tooth enamel should not be used directly to evaluate the paleo-elevation of the Tibetan Plateau, because oxygen isotopic composition from tooth enamel is a com-bination of drinking water (precipitation-and river-sourced) and diet (plant-sourced). Moreover, an empirical relationship between oxygen isotope of tooth enamel and modern river water, and as well as elevation is recommended, which can be used in future studies of Tibetan Plateau paleoelevation.XU Qiang DING Lin ZHANG LiYun YANG Di CAI FuLong LAI QingZhou LIU Jing SHI RenDeng 2010Chinese Science Bulletin2010,55,1:4
7Tailoring the Meso-Structure of Gold Nanoparticles in Keratin-Based Activated Carbon Toward High-Performance Flexible Sensor显示文摘Flexible biosensors with high accuracy and reliable operation in detecting pH and uric acid levels in body fluids are fabricated using well-engineered metaldoped porous carbon as electrode material.The gold nanoparticles@N-doped carbon in situ are prepared using wool keratin as both a novel carbon precursor and a stabilizer.The conducting electrode material is fabricated at 500℃ under customized parameters,which mimics A-B type(two different repeating units) polymeric material and displays excellent deprotonation performance(pH sensitivity).The obtained pH sensor exhibits high pH sensitivity of 57 mV/pH unit and insignificant relative standard deviation of 0.088%.Conversely,the composite carbon material with sp^2 structure prepared at 700℃ is doped with nitrogen and gold nanoparticles,which exhibits good conductivity and electrocatalytic activity for uric acid oxidation.The uric acid sensor has linear response over a range of 1-150 μM and a limit of detection 0.1 μM.These results will provide new avenues where biological material will be the best start,which can be useful to target contradictory applications through molecular engineering at mesoscale.Aniruddha BPatil Zhaohui Meng Ronghui Wu Liyun Ma Zijie Xu Chenyang Shi Wu Qiu Qiang Liu Yifan Zhang Youhui Lin Naibo Lin Xiang Yang Liu 2020Nano-Micro Letters2020,12,9:3
8New evidence for microstructural evolution model of acid-activated montmorillonite显示文摘Ca-montmorillonite samples from Choushan treated at various acid concentrations were studied using chemical analysis, XRD, 29Si and 27A1 MAS NMR, to investigate the microstructure of the activated montmorillonites. With the increase of acid concentration and dissolution of cations of montmorillonite, the intensity of d(001) decreased obviously and significant changes of the microstructure of Si and Al occurred. There were two new types of structural units of Si atoms formed: (SiO)3SiOH units and Q4(0A1) units. For Al atoms, in the course of activation, the removal of one of a pair of octahedral aluminium atoms from montmorillonite removed two hydroxyl groups and left the other aluminum of the pair in the four-fold coordination. The 27A1 signal at 5 54.0 corresponding to AlIV arose from the four-coordinated Al in the octahedral sheet. This study first confirmed, by 29Si and 27A1 MAS NMR spectra, that the model of microstructural evolution for activated montmorillonite postulated by Thomas et al.

9Light amplified oxidative stress in tumor microenvironment by carbonized hemin nanoparticles for boosting photodynamic anticancer therapy显示文摘Photodynamic therapy(PDT),which utilizes light excite photosensitizers(PSs)to generate reactive oxygen species(ROS)and consequently ablate cancer cells or diseased tissue,has attracted a great deal of attention in the last decades due to its unique advantages.However,the advancement of PDT is restricted by the inherent characteristics of PS and tumor microenvironment(TME).It is urgent to explore high-performance PSs with TME regulation capability and subsequently improve the therapeutic outcomes.Herein,we reported a newly engineered PS of polymer encapsulated carbonized hemin nanoparticles(P-CHNPs)via a facile synthesis procedure for boosting photodynamic anticancer therapy.Solvothermal treatment of hemin enabled the synthesized P-CHNPs to enhance oxidative stress in TME,which could be further amplified under light irradiation.Excellent in vitro and in vivo PDT effects were achieved due to the improved ROS(hydroxyl radicals and singlet oxygen)generation efficiency,hypoxia relief,and glutathione depletion.Moreover,the superior in vitro and in vivo biocompatibility and boosted PDT effect make the P-CHNPs a potential therapeutic agent for future translational research.Liyun Lin Wen Pang Xinyan Jiang Shihui Ding Xunbin Wei Bobo Gu 2022Light(Science & Applications)2022,11,3:2

12High-Efficiency Wastewater Purification System Based on Coupled Photoelectric–Catalytic Action Provided by Triboelectric Nanogenerator显示文摘It is of great importance to explore a creative route to improve the degradation e ciency of organic pollutants in wastewater.Herein,we construct a unique hybrid system by combining self-powered triboelectric nanogenerator(TENG)with carbon dots-TiO_(2)sheets doped three-dimensional graphene oxide photocatalyst(3 DGA@CDs-TNs),which can significantly enhance the degradation e ciency of brilliant green(BG)and direct blue 5 B(DB)owing to the powerful interaction of TENG and 3 DGA@CDs-TNs photocatalyst.The power output of TENG can be applied for wastewater purification directly,which exhibits a selfpowered electrocatalytic technology.Furthermore,the results also verify that TENG can replace conventional electric catalyst to remove pollutants e ectively from wastewater without any consumption.Subsequently,the unstable fragments and the plausible removal pathways of the two pollutants are proposed.Our work sheds light on the development of e cient and sustainable TENG/photocatalyst system,opening up new opportunities and possibilities for comprehensive utilization of random energy.Shen Shen Jiajia Fu Jia Yi Liyun Ma Feifan Sheng Chengyu Li Tingting Wang Chuan Ning Hongbo Wang Kai Dong Zhong Lin Wang 2021Nano-Micro Letters2021,13,12:1
13Optimal compatible doses and effects of ephedrine and naloxone on neural plasticity in cerebral ischemia/reperfusion rats显示文摘BACKGROUND: Ephedrine promotes neural plasticity in rats following cerebral ischemia/reperfusion injury. Ephedrine has been combined with naloxone in some studies, and it has been confirmed that their combination has synergistic effects on increasing neural plasticity following cerebral ischemia/reperfusion injury. OBJECTIVE: To investigate the effects of ephedrine combined with various doses of naloxone on neural plasticity and to find an optimal dose of naloxone in rats after cerebral ischemia/reperfusion injury by analyzing growth associated protein-43 (GAP-43), synaptophysin and β-endorphin expression in the hippocampal CA3 area. DESIGN, TIME AND SETTING: This immunohistochemical, randomized, controlled, animal experiment was performed at the Chongqing Research Institute of Pediatrics, China from September 2007 to June 2008. MATERIALS: Ephedrine hydrochloride injection and naloxone hydrochloride injection were respectively purchased from Shandong Lvliang Pharmaceutical Factory, China and Sichuan Jingwei Pharmaceutical Co., Ltd., China. A total of 192 healthy adult Sprague Dawley rats were used to establish models of left middle cerebral artery occlusion using the suture occlusion method. METHODS: At 2 hours following cerebral ischemia, the rats were intraperitoneally injected with 1.5 mg/kg/d ephedrine (ephedrine group), with 0.1, 0.2, or 0.3 mg/kg/d naloxone (low, moderate and high doses of naloxone groups), with 1.5 mg/kg/d ephedrine + 0.1, 0.2, or 0.3 mg/kg/d naloxone (ephedrine + low, moderate and high doses of naloxone groups), and with 0.5 mL saline (model group), respectively. MAIN OUTCOME MEASURES: GAP-43, synaptophysin and β-endorphin expression were detected in the hippocampal CA3 area using immunohistochemistry 1-4 weeks after surgery. Sensorimotor integration in rats was assessed using the beam walking test. RESULTS: GAP-43 and synaptophysin expression was greater in the ephedrine group, and in the ephedrine + moderate and high doses of naloxone groups compared with the model group. GAP-43 and synaptophysin expression was greatest in the ephedrine + high dose of naloxone group at 2 and 3 weeks after surgery. β-endorphin expression was significantly lower in the ephedrine group, and in the ephedrine + moderate and high doses of naloxone groups compared with the model group (P < 0.05). β-endorphin expression was persistently low in the ephedrine + high dose of naloxone group. At 1–3 weeks after surgery, the beam walking test score was significantly higher in the ephedrine group and ephedrine + various doses of naloxone groups than in the model group (P < 0.05). The score was higher in the ephedrine + moderate and high doses of naloxone groups than in the ephedrine group (P < 0.05). Moreover, the score was increased as the dose of naloxone increased in the ephedrine + various doses of naloxone groups. CONCLUSION: Ephedrine promotes GAP-43 and synaptophysin expression, inhibits β-endorphin expression in the hippocampal CA3 area, and improves motor function in rats following cerebral ischemia/reperfusion injury. Naloxone does not have the above-mentioned effects. During combined treatment with ephedrine and naloxone, however, the above-described effects are enhanced with an increased dose of naloxone. The combination of ephedrine (1.5 mg/kg/d) and naloxone (0.3 mg/kg/d) can produce optimal therapeutic efficacy in treatment of cerebral ischemic injury.Yuxia Chen Nong Xiao Xiaoping Zhang Ling Liu Liyun Lin Siyuan Chen Bei XU 2008Neural Regeneration Research2008,3,12:1

19TGA factors promote plant root growth by modulating redox homeostasis or response显示文摘To identify novel regulators of stem cell renewal,we mined an existing but little explored cell typespecific transcriptome dataset for the Arabidopsis root.A member of the TGA family of transcription factors,TGA8,was found to be specifically expressed in the quiescent center(QC).Mutation in TGA8 caused a subtle root growth phenotype,suggesting functional redundancy with other TGA members.Using a promoter::HGFP transgenic approach,we showed that all TGA factors were expressed in the root,albeit at different levels and with distinct spatial patterns.Mutant analyses revealed that all TGA factors examined contribute to root growth by promoting stem cell renewal,meristem activity,and cell elongation.Combining transcriptome analyses,histochemical assays,and physiological tests,we demonstrated that functional redundancy exists among members of cladesⅡandⅤor those in cladesⅠandⅢ.These two groups of TGA factors act differently,however,as their mutants responded to oxidative stress differently and quantitative reverse transcription polymerase chain reaction assays showed they regulate different sets of genes that are involved in redox homeostasis.Our study has thus uncovered a previously unrecognized broad role and a mechanistic explanation for TGA factors in root growth and development.Xiaochen Hu Liyun Yang Mengfei Ren Lin Liu Jing Fu Hongchang Cui 2022Journal of Integrative Plant Biology2022,64,8:1
