2Screening for main components associated with the idiosyncratic hepatotoxicity of a tonic herb, Polygonum multiflorum显示文摘典型药用的植物的主要成分,蓼 multiflorum (用汉语的 Heshouwu ) ,那导致特质的肝损害仍然保持不清楚。我们的以前的工作证明了有 lipopolysaccharide (LPS ) 的无毒的剂量和 Heshouwu 的治疗学的剂量的 cotreatment 能在老鼠导致肝损害,而独唱治疗不能导致看得见的损害。在现在的工作,用成分大美人和敲门在里面策略,我们发现 Heshouwu 的乙醇醋酸盐(EA ) 摘录在对待 LPS 的老鼠显示了可比较的特质的 hepatotoxicity 到整个摘录。结果显示血浆丙氨酸 aminotransferase, aspartate aminotransferase,和肝 histologic 的重要举起变化,而另外的分开的部分没能导致肝损害。有另外的分开的部分的 EA 摘录的混合在对待 LPS 的老鼠导致了可比较的特质的 hepatotoxicity 到整个摘录。化学分析进一步揭示了那 2,3,5,4-tetrahydroxy trans-stilbene-2-O -- 配糖物(trans-SG ) 和它的 cis 异构体是在 EA 的二主要混合物摘录。而且,孤立的 cis- ,并且不它的 trans 异构体,显示的可比较的特质的 hepatotoxicity 到在对待 LPS 的老鼠的 EA 摘录。cis-SG 的更高的内容从与收集的将军相比与 Heshouwu 联系的实际的肝沉醉病人在 Heshouwu 白酒或准备被检测样品。另外,血浆 metabolomics 分析证明 cis-SG-disturbing 充实显著地不同于的小径在对待 LPS 的老鼠的 trans-SG。所有这些结果建议 cis-SG 仔细与 Heshouwu 的特质的 hepatotoxicity 被联系。认为 trans-SG 的 cis-trans 异构化被紫外光或日光调停,我们的调查结果为在药发现控制 photoisomerization 并且为 Heshouwu 和芪相关的药的临床的使用用作参考。Chunyu Li Ming Niu Zhaofang Bai Congen Zhang Yanling Zhao Ruiyu Li Can Tu Huifang Li Jing Jing Yakun Meng Zhijie Ma Wuwen Feng Jinfa Tang Yun Zhu Jinjie Li Xiaoya Shang Zhengsheng Zou Xiaohe Xiao Jiabo Wang 2017Frontiers of Medicine2017,11,2:41
3A putative 6-transmembrane nitrate transporter OsNRT1.1b plays a key role in rice under low nitrogen显示文摘OsNRT1.1a is a low-affinity nitrate(NO_3^-) transporter gene. In this study, another mRNA splicing product, OsNRT1.1b,putatively encoding a protein with six transmembrane domains, was identified based on the rice genomic database and bioinformatics analysis. OsNRT1.1a/OsNRT1.1b expression in Xenopus oocytes showed OsNRT1.1a-expressing oocytes accumulated ^(15)N levels to about half as compared to OsNRT1.1bexpressing oocytes. The electrophysiological recording of OsNRT1.1b-expressing oocytes treated with 0.25 mM NO_3^- confirmed ^(15)N accumulation data. More functional assays were performed to examine the function of OsNRT1.1b in rice. The expression of both OsNRT1.1a and OsNRT1.1b was abundant in roots and downregulated by nitrogen(N) deficiency. The shoot biomass of transgenic rice plants with OsNRT1.1a or OsNRT1.1b overexpression increased under various N supplies under hydroponic conditions compared to wild-type(WT). The OsNRT1.1a overexpression lines showed increased plant N accumulation compared to the WT in 1.25 mM NH_4NO_3 and 2.5 mM NO_3^- or NH_4^+ treatments, but not in 0.125 mM NH_4NO_3.However, OsNRT1.1b overexpression lines increased total N accumulation in all N treatments, including 0.125 m M NH_4NO_3,suggesting that under low N condition, OsNRT1.1b would accumulate more N in plants and improve rice growth, but also that OsNRT1.1a had no such function in rice plants.Xiaorong Fan Huimin Feng Yawen Tan Yanling Xu Qisong Miao Guohua Xu 2016Journal of Integrative Plant Biology2016,58,6:21
4Gene expression signatures for phlegm-dampness constitution of Chinese Medicine显示文摘Dear Editor,The term'individualized medicine'was first used in Biochemistry Individuality in 1956 by Williams(Williams et al.,1956).With the emergence of the post-genome era in the21st century,individualized precision medicine has attracted increasing attention.In traditional Chinese medicine(TCM),there is also concept of individualized medicine,which is known as the Chinese constitutional theory,proposed in the1970s(Wang,2012).According to this theory,theLingru Li Juan Feng Haiqiang Yao Lan Xie Yu Chen Lingling Yang Shujuan Hou Shipeng Zhao Ranran Sun Yanling Wu Tongtong Bai Yingshuai Li Ruoxi Yu Ji Wang Qi Wang 2017Science China(Life Sciences)2017,60,1:13
5Platelet-rich plasma gel in combination with Schwann cells for repair of sciatic nerve injury显示文摘Bone marrow mesenchymal stem cells were isolated from New Zealand white rabbits, culture-expanded and differentiated into Schwann cell-like cells. Autologous platelet-rich plasma and Schwann cell-like cells were mixed in suspension at a density of 1 × 10 6 cells/mL, prior to introduction into a poly (lactic-co-glycolic acid) conduit. Fabricated tissue-engineered nerves were implanted into rabbits to bridge 10 mm sciatic nerve defects (platelet-rich plasma group). Controls were established using fibrin as the seeding matrix for Schwann cell-like cells at identical density to construct tissue-engineered nerves (fibrin group). Twelve weeks after implantation, toluidine blue staining and scanning electron microscopy were used to demonstrate an increase in the number of regenerating nerve fibers and thickness of the myelin sheath in the platelet-rich plasma group compared with the fibrin group. Fluoro-gold retrograde labeling revealed that the number of Fluo-ro-gold-positive neurons in the dorsal root ganglion and the spinal cord anterior horn was greater in the platelet-rich plasma group than in the fibrin group. Electrophysiological examination confirmed that compound muscle action potential and nerve conduction velocity were superior in the plate-let-rich plasma group compared with the fibrin group. These results indicate that autologous plate-let-rich plasma gel can effectively serve as a seeding matrix for Schwann cell-like cells to construct tissue-engineered nerves to promote peripheral nerve regeneration.Fagang Ye Haiyan Li Guangxi Qiao Feng Chen Hao Tao Aiyu Ji Yanling Hu 2012Neural Regeneration Research2012,7,29:11

7Proteome analysis of hepatic non-parenchymal cells of immune liver fibrosis rats显示文摘Elucidation of the mechanisms of liver fibrogenesis is important to treat liver fibrosis.In this study,we established rat models of liver fibrosis with stages from 0–1,2,and 3–4 to 4 at 2,4,6,and 8 weeks,respectively,by injection of pig serum.Liver fibrogenesis was detected by Masson’s trichrome staining.Rat non-parenchymal cells(NPCs)were enriched 4-fold by Percoll density gradient centrifugation.Protein extracts from NPCs were prepared at 4 and 8 weeks,separated by two-dimensional electrophoresis,and then stained with Coomassie Blue G-250.At 4 weeks,we identified 18 non-redundant differentially expressed proteins of which protein disulfide-isomerase associated protein 3(PDIA3)and NDUV showed consistent expression at protein and mRNA levels from 4 to 8 weeks.PDIA3 was found to be down-regulated by Western blotting in the rat model and immunohistochemically in human liver.Our results revealed important aspects of the pathogenesis/progression of liver fibrosis and demonstrated important changes in protein expression levels of NPCs at various stages of liver fibrosis.ZHAO QianQian FENG YanLing JIA XiaoFang YIN Lin ZHENG Ye OUYANG DongSheng ZHOU HongHao ZHANG LiJun 2014Science China(Life Sciences)2014,57,3:5
8Effect of Rhizobacterium Rhodopseudomonas palustris Inoculation on Stevia rebaudiana Plant Growth and Soil Microbial Community显示文摘There is an increasing concern that the continuous use of chemical fertilizers might lead to harmful effects on soil ecosystem.Accordingly, a biocompatible approach involving inoculation of beneficial microorganisms is presented to promote plant growth and simultaneously minimize the negative effect of chemical fertilizers. In this study, Rhodopseudomonas palustris, a plant growth-promoting rhizobacterium(PGPR), was inoculated into both fertilized and unfertilized soils to assess its influence on Stevia rebaudiana plant growth and microbial community in rhizosphere soils in a 122-d field experiment. Soil enzyme assays(dehydrogenase, urease, invertase, and phosphomonoesterase), real-time quantitative polymerase chain reaction(RT-_qPCR), and a high-throughput sequencing technique were employed to determine the microbial activity and characterize the bacterial community. Results showed that the R.palustris inoculation did not significantly influence Stevia yields and root biomass in either the fertilized or unfertilized soil. Chemical fertilization had strong negative effects on soil bacterial community properties, especially on dehydrogenase and urease activities.However, R. palustris inoculation counteracted the effect of chemical fertilizer on dehydrogenase and urease activities, and increased the abundances of some bacterial lineages(including Bacteroidia, Nitrospirae, Planctomycetacia, Myxococcales, and Legionellales). In contrast, inoculation into the unfertilized soil did not significantly change the soil enzyme activities or the soil bacterial community structure. For both the fertilized and unfertilized soils, R. palustris inoculation decreased the relative abundances of some bacterial lineages possessing photosynthetic ability, such as Cyanobacteria, Rhodobacter, Sphingomonadales, and Burkholderiales. Taken together, our observations stress the potential utilization of R. palustris as PGPR in agriculture, which might further ameliorate the soil microbial properties in the long run.XU Jiangbing FENG Youzhi WANG Yanling LIN Xiangui 2018Pedosphere2018,28,5:5
9Autotoxicity of Phthalate Esters in Tobacco Root Exudates:Effects on Seed Germination and Seedling Growth显示文摘Autotoxicity is one of the major factors that impede continuous cropping.It is defined as the toxic influence of chemicals released from one plant species on the germination and growth of individuals of the same species.Here, in order to exam the autotoxicity of tobacco root exudates, root exudates were collected from tobacco plants grown both in cultural solution and on natural soil.Using ultraperformance liquid chromatography coupled with triple-quadrupole tandem mass spectrometry, main autotoxic chemical substances in the root exudates were identified.The autotoxic effects of suspected autotoxins on seed germination(including germination rate,germination potential, germination index, and vigor index) and seedling growth were analyzed.Dibutyl phthalate(or diisobutyl phthalate), dioctyl phthalate, and diisooctyl phthalate were identified in tobacco root exudates.It was observed that high concentrations(greater than 0.5 mmol L^(-1)) of each identified phthalate ester caused significant(P < 0.05) inhibition of tobacco seed germination and seedling growth.It can be concluded that phthalate esters such as dibutyl phthalate, diisobutyl phthalate, and diisooctyl phthalate in tobacco root exudates may play an important role in tobacco autotoxicity.DENG Jiajun ZHANG Yanling HU Jiwei JIAO Jiaguo HU Feng LI Huixin ZHANG Shixiang 2017Pedosphere2017,27,6:5
10Full-spectrum responsive photocatalytic activity via non-noble metal Bi decorated mulberry-like BiVO_(4)显示文摘Due to its appropriate bandgap(~2.4 e V)and efficient light absorption,bismuth vanadate(Bi VO_(4))shows promising photocatalysis activity.However,the charge carrier recombination and poor electron transmission often induce poor photocatalytic performance.Herein,we report a new method to in-situ synthesize non-noble metal Bi decorated mulberry-like Bi VO_(4)by a two-step calcination process.Comprehensive characterizations reveal that non-noble metal Bi nanoparticles grown in-situ on Bi VO_(4)result in the red-shift of the absorbance edge,greatly extending the light absorption from the ultraviolet into the near-infrared region.The surface plasmon resonance excitation of Bi nanoparticles and synergetic effects between Bi and Bi VO_(4)effectively improve the photocatalytic efficiency and promote the separation of photoinduced electron-hole pairs in mulberry-like Bi VO_(4).Density functional theory(DFT)calculation results further verify that the electrons are transferred from Bi to Bi VO_(4)and the formation of·OH radical in Bi/Bi VO_(4)is attributed to the lower simulated free energy,which supports our experimental outcomes.This work provides a novel strategy to enhance light absorption and promote efficient solar utilization of photocatalysts for practical applications.Yaxin Bi Yanling Yang Xiao-Lei Shi Lei Feng Xiaojiang Hou Xiaohui Ye Li Zhang Guoquan Suo Siyu Lu Zhi-Gang Chen 2021Journal of Materials Science & Technology2021,,24:2

12Clinical application of traditional herbal medicine in five countries and regions: Japan;South Korea;China's Mainland;Hong Kong, China;Taiwan, China显示文摘Objective:To study the characteristics of the clinical application of traditional herbal medicine in five countries and regions where traditional medicine(TM)is widely used:Japan;South Korea;China's Mainland;Hong Kong,China;Taiwan,China.And to analyze,from multiple angles,the variations in the methods of TM used in each countries and regions.Methods:Fifty commonly used traditional herbs(TOP50)from classical formulae were selected,and descriptive statistics,correlation analyses,and Friedman test were used to compare methods of clinical application and dosages in the countries and regions of interest based on a retrospective review of randomly-selected medical records.Results:There were significant differences in sequencing TOP50 among the five countries and regions(P<.01).The adherence to the classical formulae,from strong to weak was Japan;China's Mainland;Taiwan,China;Hong Kong,China;South Korea.There were also significant differences in TOP50 dosing regimens(P<.01).Overall dosages of TOP50 from high to low were:China's Mainland;Hong Kong,China;Taiwan,China;South Korea;Japan.Finally,there were significant differences in the dosage intervals(P<.01),with dosage intervals from maximum to minimum as follows:China's Mainland;Taiwan,China;Hong Kong,China;South Korea;Japan.Conclusions:The clinical dosages of traditional herbal medicine used in the China's Mainland are relatively large compared with those prescribed in the other four countries and regions,and the range of dosages in China's Mainland is more flexible.On the other hand,clinical dosages of TOP50 are the lowest in Japan,where the dosage range is also the narrowest,supporting the idea that Doctors of Kampo medicine are highly cautious and are likely to adhere strictly to classical formulae,while Hong Kong,China and Taiwan,China are in the middle.The dosage of TOP50 in South Korea is significantly lower than that used in the China's Mainland;Hong Kong,China and Taiwan,China where the adherence to the classical formulae was the lowest,albeit slightly higher than that in Japan.The methods of clinical application of traditional herbal medicine in the five countries and regions were affected by multiple factors,including history,geography,climate,and culture.Liming Chen Yanling Fu Lin Zhang Sijia Zhao Qing Feng Yihua Cheng Tosha Yanai Daji Xu Mingyu Luo Sang Woo An Woong Seok Lee Seong Hoon Cho Byung Wook Lee 2015Journal of Traditional Chinese Medical Sciences2015,2,3:1
13Efficacy and safety of single-bolus tenecteplase compared with front-loaded alteplase in Chinese patients with acute myocardial infarction显示文摘Background and Objective Previous study showed tenecteplase and alteplaxe were equovalent for 30-day mortality in the treatment of acute myocardial infarction. The purpose of this open-label,randomized,multi-center,angiographic trial was to assess the efficacy and safety of tenecteplase compared with alteplase in Chinese patients with acute myocardial infarction. Methods We recruited patients with acute ST-elevation myocardial infarction presenting within 6 hours of symptom onset from October,2002 to March,2004,in 5 hospitals in Beijing. After giving informed consent,patients were randomly assigned a single-bolus injection of tenecteplase(30-50 mg according to body weight) or front loaded alteplase(100 mg) ,and underwent coronary angiography at 90 min after starting the study drug. All patients received aspirin and heparin(target activated partial thromboplastin time 50-70 s) . The primary efficacy end point was the rate of TIMI grade 3 flow at 90 minutes. Other efficacy end points included TIMI grade 2/3 flow at 90 minutes. Safety end points included all stroke,intracranial hemorrhage(ICH) ,moderate/severe hemorrhage(except for ICH) ,all-cause mortality at 30-days,and major non-fatal cardiac events at 30 days. Results Overall 110 patients were eligible for statistical analysis,with 58 patients assigned to receive tenecteplase and 52 patients to alteplase. Tenecteplase produced a rate of TIMI grade 3 flow at 90 minutes after the start of thrombolysis(68.4%) similar to that of alteplase(66.7%,P=1.0) ;the rates of TIMI grade 2 or 3 were similar for patients treated with tenecteplase versus alteplase(89.5% versus 80.4%,respectively,P=0.278) . At 30 days,rates for all strokes were similar for the two groups(5.17% for tenecteplase and 1.92% for alteplase,P=0.62) ;rates of ICH were 3.45% and 1.92%(tenecteplase and rt-PA,P=1.00) respectively. The rate of moderate/severe hemorrhage was 8.62% with tenecteplase and 5.77% with alteplase(P=0.72) ;total mortality was almost identical in the two groups(13.8% versus 9.6%,respectively,P=0.565) while the rates of non-fatal cardiac complications were 10.35% and 11.54%(tenecteplase and alteplase,P=1.0) . Conclusions The efficacy of a single-bolus,weight-adjusted tenecteplase fibrinolytic regimen is equivalent to front-loaded alteplase in terms of the rates of TIMI grade 3 flow,and TIMI 2 or 3 flow,but the 30-day mortality and ICH in both groups was so high that the use of tenecteplase is not permitted in China. These negative safety results might be due to the high rate of percutaneous coronary intervention(PCI) and high dose of bolus heparin and suboptimal concomitant medical therapy during hospitalization,so further studies are needed to confirm the safety for tenecteplase in Chinese patients.Feng Liang Dayi Hu Xubo Shi Mingshu Gao Jiaping Wei Hong Zhao Lei Wang Sanqing Jia Hongyu Wang Ruhuai Liu Yundai Chen Yanling Lu 2007Journal of Geriatric Cardiology2007,4,3:1
14Construction of SnS2/SnO2 heterostructures with enhanced potassium storage performance显示文摘Increasing attention has been focused on potassium ion batteries(KIBs) as promising energy-sto rage system(ESS) owing to the abundance and low-cost of potassium resources.Here,SnS2/SnO2 hete rostructures were successfully fixed onto stainless steel mesh(SnS2/SnO2/SSM) through a facile two-step hydrothermal method and used as anodes for KIBs.Due to the advantages of SnS2/SnO2 heterostructures and good conductivity of SSM substrate,the SnS2/SnO2/SSM anodes display enhanced electrochemical performance.The SnS2/SnO2/SSM anodes deliver specific capacity of 394 mA h g^-1 at 50 mA g^-1 over 100 cycles,better than SnO2/SSM.Even at 500 mA g^-1 after 250 cycles,high capacity of 155 mA h g^-1 can still be obtained.Guoquan Suo Dan Li Lei Feng Xiaojiang Hou Xiaohui Ye Li Zhang Qiyao Yu Yanling Yang Wei(Alex)Wang 2020Journal of Materials Science & Technology2020,52,20:1
