| 2 | Hydrophobicity mechanism of non-smooth pattern on surface of butterfly wing显示文摘Twenty-nine species (24 genera, 6 families) of butterflies typical and common in northeast China were selected to make qualitative and quantitative studies on the pattern, hydrophobicity and hydrophobicity mechanism by means of scanning electron microscopy and contact angle measuring system. The scale surface is composed of submicro-class vertical gibbosities and horizontal links. The distance of scale is 48—91 μm, length 65—150 μm, and width 35—70 μm. The distance of submicro-class vertical gib-bosities on scale is 1.06—2.74 μm, height 200—900 nm, and width 200—840 nm. The better hydropho-bicity on the surface of butterfly wing (static contact angle 136.3°—156.6°) is contributed to the co-effects of micro-class scale and submicro-class vertical gibbosities on the wing surface. The Cassie equation was revised, and new mathematical models and equations were established. | FANG Yan SUN Gang WANG TongQing CONG Qian REN LuQuan | 2007 | Chinese Science Bulletin2007,52,5: | 31 |

| 4 | Palaeogene fossil Populus leaves from Lanzhou Basin and their palaeoclimatic significance显示文摘An angiosperm compression flora is found in Palaeogene from Lanzhou Basin and the cuticular analysis of Populus davidiana Dode in the flora is carefully made. Fur-thermore, the fossil cuticles are compared with the epidermal structures of extant Populus leaves growing in different en-vironments, i.e. moist, semimoist, and semiarid to arid cli-matic regions. The present experiments indicate that mature leaves of P. davidiana show leaf size from big to small, leaf cuticles from thick to thin and anticlinal walls of epidermal cells from faintness to clarity along with the increase of lati-tudes of the plant distributions, the climatic variation from moist to arid, the annual precipitation from more to less and the annual mean temperature from high to low. The fossil P. davidiana differs from the specimens collected from Shandan in semiarid to arid climatic regions but closely resembles the Wushan leaves in a semi-moist climatic area in a lot of fea-tures. In a word, the new research may reflect that the flora lives in a semi-moist climatic environment. The present dis-covery of compression of Paleogene Populus davidiana is of great significance to studying vegetation types, climatic and environmental changes during the primal uplifting of the Qinghai-Tibet Plateau. | SUN Bainian1,2, YAN Defei1, XIE Sanping1, CONG Peiyun1, XIN Cunlin1 & YUN Fei1 1.

| 6 | Effects of Methanol on Wettability of the Non-Smooth Surface on Butterfly Wing显示文摘The contact angles of distilled water and methanol solution on the wings of butterflies were determined by a visual contact angle measuring system.The scale structures of the wings were observed using scanning electron microscopy,The influence of the scale micro-and ultra-structure on the wettability was investigated.Results show that the contact angle of distilled water on the wing surfaces varies from 134.0° to 159.2°.High hydrophobicity is found in six species with contact angles greater than 150°.The wing surfaces of some species are not only hydrophobic but also resist the wetting by methanol solution with 55% concentration.Only two species in Parnassius can not resist the wetting because the micro-structure(spindle-like shape) and ultra-structure(pinnule-like shape) of the wing scales are remarkably different from that of other species.The concentration of methanol solution for the occurrence of spreading/wetting on the wing surfaces of different species varies from 70% to 95%.After wetting by methanol solution for 10 min,the distilled water contact angle on the wing surface increases by 0.8°-2.1°,showing the promotion of capacity against wetting by distilled water. | Yan Fang Gang Sun Qian Cong Guang-hua Chen Lu-quan Ren | 2008 | Journal of Bionic Engineering2008,5,2: | 19 |
| 7 | Synergistic Effects of Chuanxiong-Chishao Herb-Pair on Promoting Angiogenesis at Network Pharmacological and Pharmacodynamic Levels显示文摘Objective: To investigate the synergistic effects of Chuanxiong-Chishao herb-pair(CCHP) on promoting angiogenesis in silico and in vivo. Methods: The mechanisms of action of an herb-pair, ChuanxiongChishao, were investigated using the network pharmacological and pharmacodynamic strategies involving computational drug target prediction and network analysis, and experimental validation. A set of network pharmacology methods were created to study the herbs in the context of targets and diseases networks, including prediction of target profiles and pharmacological actions of main active compounds in Chuanxiong and Chishao. Furthermore, the therapeutic effects and putative molecular mechanisms of Chuanxiong-Chishao actions were experimentally validated in a chemical-induced vascular insufficiency model of transgenic zebrafish in vivo. The m RNA expression of the predicted targets were further analyzed by real-time polymerase chain reaction(RT-PCR). Results: The computational prediction results found that the compounds in Chuanxiong have antithrombotic, antihypertensive, antiarrhythmic, and antiatherosclerotic activities, which were closely related to protecting against hypoxic-ischemic encephalopathy, ischemic stroke, myocardial infarction and heart failure. In addition, compounds in Chishao were found to participate in anti-inflammatory effect and analgesics. Particularly, estrogen receptor α(ESRα) and hypoxia-inducible factor 1-α(HIF-1α) were the most important potential protein targets in the predicted results. In vivo experimental validation showed that post-treatment of tetramethylpyrazine hydrochloride(TMP·HCl) and paeoniflorin(PF) promoted the regeneration of new blood vessels in zebrafish involving up-regulating ESRα m RNA expression. Co-treatment of TMP·HCl and PF could enhance the vessel sprouting in chemical-induced vascular insufficiency zebrafish at the optimal compatibility proportion of PF 10 μmol/L with TMP·HCl 1 μmol/L. Conclusions: The network pharmacological strategies combining drug target prediction and network analysis identified some putative targets of CCHP. Moreover, the transgenic zebrafish experiments demonstrated that the Chuanxiong-Chishao combination synergistically promoted angiogenic activity, probably involving ESRα signaling pathway. | WANG Yan GUO Gang YANG Bin-rui XIN Qi-qi LIAO Qi-wen LEE Simon Ming-Yuen HU Yuan-jia CHEN Ke-ji CONG Wei-hong | 2017 | Chinese Journal of Integrative Medicine2017,23,9: | 19 |

| 10 | Oral berberine improves brain dopa/dopamine levels to ameliorate Parkinson’s disease by regulating gut microbiota显示文摘The phenylalanine-tyrosine-dopa-dopamine pathway provides dopamine to the brain.Iin this process,tyrosine hydroxylase(TH)isthe rate-limiting enzyme that hydroxylates tyrosine and generates levodopa(L-dopa)with tetranydrobiopterin(BH_(4))as a coenzyme.Here,we show that oral berberine(BBR)might supply H^(·) through dihydroberberine(reduced BBR produced by bacterial nitroreductase)and promote the production of BHl from dihydrobiopterin;the increased BH,enhances TH activity,which accelerates the production of L-dopa by the gut bacteria.Oral BBR acts in a way similar to vitamins.The L-dopa produced by theintestinal bacteria enters the brain through the circulation and is transformed to dopamine.To verify the gut-brain dialog activatedby BBR's effect,Enterococcus foecalis or Enterococcus faecium was transplanted into Parkinson's disease(PD)mice.The bacteriasignificantly increased brain dopamine and ameliorated PD manifestation in mice;additionally,combination of BBR with bacteriashowed better therapeutic effect than that with bacteria alone.Moreover,2,4,6-trimethy-pyranylium tetrafluoroborate(TMP-TFB)-derivatized matrix-assisted laser desorption mass spectrometry(MALDI-MS)imaging of dopamine identihed elevated striataldopamine levels in mouse brains with oral Enterococcus,and BBR strengthened the imaging intensity of brain dopamine.Theseresults demonstrated that BBR was an agonist of TH in Enterococcus and could lead to the production of L-dopa in the gut.Furthermore,a study of 28 patients with hyperlipidemia conhrmed that oral BBR increased bloodfecal L-dopa by the intestinalbacteria.Hence,BBR might improve the brain function by upregulating the biosynthesis of-dopa in the gut microbiota through avitamin-like effect. | Yan Wang Qian Tong Shu-Rong Ma Zhen-Xiong Zhao Li-Bin Pan Lin Cong Pei Han Ran Peng Hang Yu Yuan Lin Tian-Le Gao Jia-Wen Shou Xiao-Yang Li Xian-Feng Zhang Zheng-Wei Zhang Jie Fu Bao-Ying Wen Jin-Bo Yu Xuetao Cao Jian-Dong Jiang | 2021 | Signal Transduction and Targeted Therapy2021,6,3: | 16 |

| 12 | The Chromosome-Based Rubber Tree Genome Provides New Insights into Spurge Genome Evolution and Rubber Biosynthesis显示文摘The rubber tree,Hevea brasiliensis,produces natural rubber that serves as an essential industrial raw material.Here,we present a high-quality reference genome for a rubber tree cultivar GT1 using single-molecule real-time sequencing(SMRT)and Hi-C technologies to anchor the~1.47-Gb genome assembly into 18 pseudochromosomes.The chromosome-based genome analysis enabled us to establish a model of spurge chromosome evolution,since the common paleopolyploid event occurred before the split of Hevea and Manihot.We show recent and rapid bursts of the three Hevea-specific LTR-retrotransposon families during the last 10 million years,leading to the massive expansion by~65.88%(~970 Mbp)of the whole rubber tree genome since the divergence from Manihot.We identify large-scale expansion of genes associated with whole rubber biosynthesis processes,such as basal metabolic processes,ethylene biosynthesis,and the activation of polysaccharide and glycoprotein lectin,which are important properties for latex production.A map of genomic variation between the cultivated and wild rubber trees was obtained,which contains~15.7 million high-quality single-nucleotide polymorphisms.We identified hundreds of candidate domestication genes with drastically lowered genomic diversity in the cultivated but not wild rubber trees despite a relatively short domestication history of rubber tree,some of which are involved in rubber biosynthesis.This genome assembly represents key resources for future rubber tree research and breeding,providing novel targets for improving plant biotic and abiotic tolerance and rubber production. | Jin Liu Cong Shi Cheng-Cheng Shi Wei Li Qun-Jie Zhang Yun Zhang Kui Li Hui-Fang Lu Chao Shi Si-Tao Zhu Zai-Yun Xiao Hong Nan Yao Yue Xun-Ge Zhu Yu Wu Xiao-Ning Hong Guang-Yi Fan Yan Tong Dan Zhang Chang-Li Mao Yun-Long Liu Shi-Jie Hao Wei-Qing Liu Mei-Qi Lv Hai-Bin Zhang Yuan Liu Ge-Ran Hu-tang Jin-Peng Wang Jia-Hao Wang Ying-Huai Sun Shu-Bang Ni Wen-Bin Chen Xing-Cai Zhang Yuan-Nian Jiao Evan E.Eichler Guo-Hua Li Xin Liu Li-Zhi Gao | 2020 | Molecular Plant2020,13,2: | 15 |
| 13 | Effective components of Chinese herbs reduce central nervous system function decline induced by iron overload显示文摘Abnormally increased levels of iron in the brain trigger cascade amplification in Alzheimer's disease patients,resulting in neuronal death.This study investigated whether components extracted from the Chinese herbs epimedium herb,milkvetch root and kudzuvine root could relieve the abnormal expression of iron metabolism-related protein in Alzheimer's disease patients.An APPswe/PS1ΔE9 double transgenic mouse model of Alzheimer's disease was used.The intragastric administration of compounds from epimedium herb,milkvetch root and kudzuvine root improved pathological alterations such as neuronal edema,increased the number of neurons,downregulated divalent metal transporter 1 expression,upregulated ferroportin 1 expression,and inhibited iron overload in the cerebral cortex of mice with Alzheimer's disease.These compounds reduced iron overload-induced impairment of the central nervous system,indicating a new strategy for developing novel drugs for the treatment of Alzheimer's disease. | Xian-hui Dong Jiang-tao Bai Wei-na Kong Xiao-ping He Peng Yan Tie-mei Shao Wen-guo Yu Xi-qing Chai Yan-hua Wu Cong Liu | 2015 | Neural Regeneration Research2015,10,5: | 14 |
| 14 | Radiomics approach for preoperative identification of stages Ⅰ-Ⅱand Ⅲ-Ⅳ of esophageal cancer显示文摘Objective: To predict preoperative staging using a radiomics approach based on computed tomography(CT)images of patients with esophageal squamous cell carcinoma(ESCC).Methods: This retrospective study included 154 patients(primary cohort: n=114; validation cohort: n=40) with pathologically confirmed ESCC. All patients underwent a preoperative CT scan from the neck to abdomen. High throughput and quantitative radiomics features were extracted from the CT images for each patient. A radiomics signature was constructed using the least absolute shrinkage and selection operator(Lasso). Associations between radiomics signature, tumor volume and ESCC staging were explored. Diagnostic performance of radiomics approach and tumor volume for discriminating between stages Ⅰ-Ⅱ and Ⅲ-Ⅳ was evaluated and compared using the receiver operating characteristics(ROC) curves and net reclassification improvement(NRI).Results: A total of 9,790 radiomics features were extracted. Ten features were selected to build a radiomics signature after feature dimension reduction. The radiomics signature was significantly associated with ESCC staging(P<0.001), and yielded a better performance for discrimination of early and advanced stage ESCC compared to tumor volume in both the primary [area under the receiver operating characteristic curve(AUC): 0.795 vs. 0.694,P=0.003; NRI=0.424)] and validation cohorts(AUC: 0.762 vs. 0.624, P=0.035; NRI=0.834).Conclusions: The quantitative approach has the potential to identify stage Ⅰ-Ⅱ and Ⅲ-Ⅳ ESCC before treatment. | Lei WU Cong Wang Xianzheng Tan Zixuan Cheng Ke Zhao Lifen Yan Yanli Liang Zaiyi Liu Changhong Liang | 2018 | Chinese Journal of Cancer Research2018,30,4: | 14 |
| 15 | A single Eu^(2+)-activated high-color-rendering oxychloride white-light phosphor for white-light-emitting diodes显示文摘Single-phased,high-color-rendering index(CRI)white-light phosphors are emerging as potential phosphor-converted white-light-emitting diodes(WLEDs)and as an alternative to blends of tricolor phosphors.However,it is a challenge to create a high CRI white light from a single-doped activator.Here,we present a high CRI(Ra 591)white-light phosphor,Sr_(5)(PO_(4))_(3-x)(BO_(3))_(x)Cl:Eu^(2+),composed of Sr5(PO4)3Cl as the beginning member and Sr_(5)(BO_(3))_(3)Cl as the end member.This work utilized the solid-solution method,and tunable Eu^(2+) emission was achieved.Color-tunable Eu^(2+) emissions in response to structural variation were observed in Sr_(5)(PO_(4))_(3-x)(BO_(3))_(x)Cl solid solutions.This was further confirmed using X-ray Rietveld refinement,electron paramagnetic resonance spectroscopy,and in the photoluminescence spectra.The color-tunable emissions included the white light that originated from the combination of the blue emission of Sr_(5)(PO_(4))_(3)Cl:Eu^(2+) and an induced Eu^(2+) yellow emission at approximately 550 nm in the solid solution.Importantly,the white-light phosphors showed a greater R9590.2 under excitation at 365 nm.This result has rarely been reported in the literature and is greater than that of(R9514.3)commercial Y_(3)A_(l5)O_(12):Ce^(3+)-based WLEDs.These findings demonstrate the great potential of Sr_(5)(PO_(4))_(3-x)(BO_(3))_(x)Cl:0.04Eu^(2+) as a white-light phosphor for near-UV phosphor-converted WLEDs.These results also provide a shortcut for developing a high CRI white-light phosphor from a single Eu^(2+)-doped compound. | Peng-Peng Dai Cong Li Xin-Tong Zhang Jun Xu Xi Chen Xiu-Li Wang Yan Jia Xiaojun Wang Yi-Chun Liu | 2016 | Light(Science & Applications)2016,5,1: | 14 |
| 16 | Characteristics of PM_(2.5) pollution in Beijing after the improvement of air quality显示文摘Following the implementation of the strictest clean air policies to date in Beijing,the physicochemical characteristics and sources of PM_(2.5) have changed over the past few years.To improve pollution reduction policies and subsequent air quality further,it is necessary to explore the changes in PM_(2.5) over time.In this study,over one year(2017-2018)field study based on filter sampling(TH-150C;Wuhan Tianhong,China)was conducted in Fengtai District,Beijing,revealed that the annual average PM_(2.5) concentration(64.8±43.1μg/m^3)was significantly lower than in previous years and the highest PM_(2.5) concentration occurred in spring(84.4±59.9μg/m^3).Secondary nitrate was the largest source and accounted for 25.7%of the measured PM_(2.5).Vehicular emission,the second largest source(17.6%),deserves more attention when considering the increase in the number of motor vehicles and its contribution to gaseous pollutants.In addition,the contribution from coal combustion to PM_(2.5) decreased significantly.During weekends,the contribution from EC and NO3−increased whereas the contributions from SO4^2−,OM,and trace elements decreased,compared with weekdays.During the period of residential heating,PM_(2.5) mass decreased by 23.1%,compared with non-heating period,while the contributions from coal combustion and vehicular emission,and related species increased.With the aggravation of pollution,the contribution of vehicular emission and secondary sulfate increased and then decreased,while the contribution of NO3−and secondary nitrate continued to increase,and accounted for 34.0%and 57.5%of the PM_(2.5) during the heavily polluted days,respectively. | Xiaojuan Huang Guiqian Tang Junke Zhang Baoxian Liu Chao Liu Jin Zhang Leilei Cong Mengtian Cheng Guangxuan Yan Wenkang Gao Yinghong Wang Yuesi Wang | 2021 | Journal of Environmental Sciences2021,33,2: | 14 |
| 17 | A multicenter,retrospective.epidemiologic survey of the clinical features and management of bone metastatic disease in China显示文摘Background:Bone metastases are common in patients with advanced cancer.Bisphosphonates(BPs) could prevent or delay the development of skeleton-related events(SREs).The present study aimed to identify the clinical features of and treatment strategies for Chinese patients with bone metastases.Methods:Consecutive cancer patients who had bone metastases and received BP treatment were enrolled.A questionnaire was developed to collect the patients' clinical data,as well as information on the diagnosis and management of bone metastases.Physicians' awareness of the guidelines and knowledge of the application of BP were also assessed.Results:A total of 3223 patients with lung cancer(36.5%),breast cancer(30.9%),prostate cancer(8.5%),and gastrointestinal cancer(5.7%) were included in this study.The sites of bone metastases were the thoracic spine(56.0%),lumbar spine(47.1%),ribs(32.6%),and pelvis(23.2%).The SRE frequency was the highest in patients with multiple myeloma(36.6%),followed by those with lung cancer(25.9%),breast cancer(20.2%),prostate cancer(18.2%),and gastrointestinal cancer(17.3%).Irradiation to the bone was the most frequent SRE(58%in lung cancer patients,45%in breast cancer patients,and 48%in prostate cancer patients).Our survey also showed that 45.5%of patients received BP within 3 months after their diagnosis of bone metastases,whereas the remaining 54.5%of patients did not receive BP treatment until at least 3 months after their diagnosis of bone metastases.The SRE frequency in the former group was significantly lower than that in the latter group(4.0%vs.42.3%,P < 0.05).In patients with more than 6 months of continuous BP treatment,the mean time to the first SRE was significantly longer than that in patients with less than 6 months of continuous BP treatment(7.2 vs.3.4 months,P < 0.05).In addition,12.2%of the physicians were not aware of the efficacy of BP in preventing and delaying SRE.Only half(52.3%) of the physicians agreed that the BP treatment should persist for at least 6 months unless it was intolerable.Conclusions:Our study suggested that prompt and persistent BP treatment was associated with a reduced risk of SREs.However,our survey also revealed that the proper application of BP was not as common as expected in China. | Yunpeng Yang Yuxiang Ma Jin Sheng Yan Huang Yuanyuan Zhao Wenfeng Fang Shaodong Hong Ying Tian Cong Xue Li Zhang | 2016 | Chinese Journal of Cancer2016,35,5: | 13 |

| 19 | Anisotropism of the Non-Smooth Surface of Butterfly Wing显示文摘Twenty-nine species of butterflies were collected for observation and determination of the wing surfaces using a ScanningElectron Microscope(SEM).Butterfly wing surface displays structural anisotropism in micro-,submicro- and nano-scales.Thescales on butterfly wing surface arrange like overlapping roof tiles.There are submicrometric vertical gibbosities,horizontallinks,and nano-protuberances on the scales.First-incline-then-drip method and first-drip-then-incline method were used tomeasure the Sliding Angle(SA)of droplet on butterfly wing surface by an optical Contact Angle(CA)measuring system.Relatively smaller sliding angles indicate that the butterfly wing surface has fine self-cleaning property.Significantly differentSAs in various directions indicate the anisotropic self-cleaning property of butterfly wing surface.The SAs on the butterfly wingsurface without scales are remarkably larger than those with scales,which proves the crucial role of scales in determining theself-cleaning property.Butterfly wing surface is a template for design and fabrication ofbiomimetic materials and self-cleaningsubstrates.This work may offer insights into how to design directional self-cleaning coatings and anisotropic wetting surface. | Gang Sun~(1,2), Yan Fang~(1,2), Qian Cong~1, Lu-quan Ren~11.
