| 1 | Rapid repair techniques for severely earthquake-damaged circular bridge piers with flexural failure mode显示文摘In this study, three rapid repair techniques are proposed to retrofit circular bridge piers that are severely damaged by the flexural failure mode in major earthquakes. The quasi-static tests on three 1:2.5 scaled circular pier specimens are conducted to evaluate the efficiency of the proposed repair techniques. For the purpose of rapid repair, the repair procedure for all the specimens is conducted within four days, and the behavior of the repaired specimens is evaluated and compared with the original ones. A finite element model is developed to predict the cyclic behavior of the repaired specimens and the numerical results are compared with the test data. It is found that all the repaired specimens exhibit similar or larger lateral strength and deformation capacity than the original ones. The initial lateral stiffness of all the repaired specimens is lower than that of the original ones, while they show a higher lateral stiffness at the later stage of the test. No noticeable difference is observed for the energy dissipation capacity between the original and repaired pier specimens. It is suggested that the repair technique using the early-strength concrete jacket confined by carbon fiber reinforced polymer(CFRP) sheets can be an optimal method for the rapid repair of severely earthquake-damaged circular bridge piers with flexural failure mode. | Sun Zhiguo Li Hongnan Bi Kaiming Si Bingjun Wang Dongsheng | 2017 | Earthquake Engineering and Engineering Vibration2017,16,2: | 8 |
| 2 | Rapid repair of severely earthquake-damaged bridge piers with flexural-shear failure mode显示文摘An experimental study was conducted to investigate the feasibility of a proposed rapid repair technique for severely earthquake-damaged bridge piers with flexural-shear failure mode. Six circular pier specimens were first tested to severe damage in flexural-shear mode and repaired using early-strength concrete with high-fluidity and carbon fiber reinforced polymers (CFRP). After about four days, the repaired specimens were tested to failure again. The seismic behavior of the repaired specimens was evaluated and compared to the original specimens. Test results indicate that the proposed repair technique is highly effective. Both shear strength and lateral displacement of the repaired piers increased when compared to the original specimens, and the failure mechanism of the piers shifted from flexural-shear failure to ductile flexural failure. Finally, a simple design model based on the Seible formulation for post-earthquake repair design was compared to the experimental results. It is concluded that the design equation for bridge pier strengthening before an earthquake could be applicable to seismic repairs after an earthquake if the shear strength contribution of the spiral bars in the repaired piers is disregarded and 1.5 times more FRP sheets is provided. | Sun Zhiguo Wang Dongsheng Du Xiuli Si Bingjun | 2011 | Earthquake Engineering and Engineering Vibration2011,10,4: | 7 |
| 3 | Experimental research and finite element analysis of bridge piers failed in flexure-shear modes显示文摘In recent earthquakes,a large number of reinforced concrete (RC) bridges were severely damaged due to mixed flexure-shear failure modes of the bridge piers.An integrated experimental and finite element (FE) analysis study is described in this paper to study the seismic performance of the bridge piers that failed in flexure-shear modes.In the first part,a nonlinear cyclic loading test on six RC bridge piers with circular cross sections is carried out experimentally.The damage states,ductility and energy dissipation parameters,stiffness degradation and shear strength of the piers are studied and compared with each other.The experimental results suggest that all the piers exhibit stable flexural response at displacement ductilities up to four before exhibiting brittle shear failure.The ultimate performance of the piers is dominated by shear capacity due to significant shear cracking,and in some cases,rupturing of spiral bars.In the second part,modeling approaches describing the hysteretic behavior of the piers are investigated by using ANSYS software.A set of models with different parameters is selected and evaluated through comparison with experimental results.The influences of the shear retention coefficients between concrete cracks,the Bauschinger effect in longitudinal reinforcement,the bond-slip relationship between the longitudinal reinforcement and the concrete and the concrete failure surface on the simulated hysteretic curves are discussed.Then,a modified analysis model is presented and its accuracy is verified by comparing the simulated results with experimental ones.This research uses models available in commercial FE codes and is intended for researchers and engineers interested in using ANSYS software to predict the hysteretic behavior of reinforced concrete structures. | Sun Zhiguo Si Bingjun Wang Dongsheng Guo Xun | 2008 | Earthquake Engineering and Engineering Vibration2008,7,4: | 6 |
| 4 | Soybean hairy roots produced in vitro by Agrobacterium rhizogenes-mediated transformation显示文摘Soybean is one of the world's most important oil and protein crops. Efficient transformation is a key factor for the improvement of soybean by genetic modification. We describe an optimized protocol for the Agrobacterium rhizogenes-mediated transformation of soybean and the induction of hairy root development in vitro. Cotyledons with 0.5-cm hypocotyls were cut from 5-day-old seedlings and used as explants. After infection and co-cultivation,hairy roots were produced in induction culture medium after 10–12 days. Using this method, 90%–99% of the infected explants of five different cultivars produced hairy roots within one month. Observations using reporter constructs showed that 30%–60% of the hairy roots induced were transformed. Based on high transformation efficiency and short transformation period, this method represents an efficient and rapid platform for study of soybean gene function. | Li Chen Yupeng Cai Xiujie Liu Chen Guo Shi Sun Cunxiang Wu Bingjun Jiang Tianfu Han Wensheng Hou | 2018 | The Crop Journal2018,6,2: | 4 |
| 5 | Erythrocyte membrane-camouflaged carrier-free nanoassembly of FRET photosensitizer pairs with high therapeutic efficiency and high security for programmed cancer synergistic phototherapy显示文摘Phototherapy has been intensively investigated as a non-invasive cancer treatment option.However,its clinical translation is still impeded by unsatisfactory therapeutic efficacy and severe phototoxicity.To achieve high therapeutic efficiency and high security,a nanoassembly of Forster Resonance Energy Transfer(FRET)photosensitizer pairs is developed on basis of dual-mode photosensitizer co-loading and photocaging strategy.For proof-of-concept,an erythrocyte-camouflaged FRET pair co-assembly of chlorine e6(Ce6,FRET donor)and 1,1′-dioctadecyl-3,3,3′,3′-tetramethylindotricarbocyanine iodide(DiR,FRET acceptor)is investigated for breast cancer treatment.Notably,Ce6 in the nanoassemby is quenched by DiR and could be unlocked for photodynamic therapy(PDT)only when DiR is photobleached by 808-nm laser.As a result,Ce6-caused phototoxicity could be well controlled.Under cascaded laser irradiation(808-660 nm),tumor-localizing temperature rise following laser irradiation on DiR not only induces tumor cell apoptosis but also facilitates the tumor penetration of NPs,relieves tumor hypoxia,and promotes the PDT efficacy of Ce6.Such FRET pair-based nanoassembly provides a new strategy for developing multimodal phototherapy nanomedicines with high efficiency and good security. | Xuanbo Zhang Jianchen Xiong Kaiyuan Wang Han Yu Bingjun Sun Hao Ye Zhiqiang Zhao Ning Wang Yuequan Wang Shenwu Zhang Wutong Zhao Haotian Zhang Zhonggui He Cong Luo Jin Sun | 2021 | Bioactive Materials2021,6,8: | 4 |
| 6 | Small changes in the length of diselenide bond-containing linkages exert great influences on the antitumor activity of docetaxel homodimeric prodrug nanoassemblies显示文摘Homodimeric prodrug-based self-assembled nanoparticles,with carrier-free structure and ultrahigh drug loading,is drawing more and more attentions.Homodimeric prodrugs are composed of two drug molecules and a pivotal linkage.The influence of the linkages on the self-assembly,in vivo fate and antitumor activity of homodimeric prodrugs is the focus of research.Herein,three docetaxel(DTX)homodimeric prodrugs are developed using different lengths of diselenide bond-containing linkages.Interestingly,compared with the other two linkages,the longest diselenide bond-containing linkage could facilitate the self-delivery of DTX prodrugs,thus improving the stability,circulation time and tumor targeting of prodrug nanoassemblies.Besides,the extension of linkages reduces the redox-triggered drug release and cytotoxicity of prodrug nanoassemblies in tumor cells.Although the longest diselenide bond-containing prodrug nanoassemblies possessed the lowest cytotoxicity to 4T1 cells,their stable nanostructure maintained intact during circulation and achieve the maximum accumulation of DTX in tumor cells,which finally“turned the table”.Our study illustrates the crucial role of linkages in homodimeric prodrugs,and gives valuable proposal for the development of advanced nano-DDS for cancer treatment. | Lingxiao Li Shiyi Zuo Fudan Dong Tian Liu Yanlin Gao Yinxian Yang Xin Wang Jin Sun Bingjun Sun Zhonggui He | 2021 | Asian Journal of Pharmaceutical Sciences2021,16,3: | 3 |
| 7 | Pure photosensitizer-driven nanoassembly with core-matched PEGylation for imaging-guided photodynamic therapy显示文摘Pure drug-assembled nanomedicines(PDANs)are currently under intensive investigation as promising nanoplatforms for cancer therapy.However,poor colloidal stability and less tumor-homing ability remain critical unresolved problems that impede their clinical translation.Herein,we report a core-matched nanoassembly of pyropheophorbide a(PPa)for photodynamic therapy(PDT).Pure PPa molecules are found to self-assemble into nanoparticles(NPs),and an amphiphilic PEG polymer(PPaPEG_(2K))is utilized to achieve core-matched PEGylating modification via the p-p stacking effect and hydrophobic interaction between the PPa core and the PPa-PEG_(2K) shell.Compared to PCL-PEG_(2K) with similar molecular weight,PPa-PEG_(2K) significantly increases the stability,prolongs the systemic circulation and improves the tumor-homing ability and ROS generation efficiency of PPa-nanoassembly.As a result,PPa/PPa-PEG_(2K) NPs exert potent antitumor activity in a 4T1 breast tumor-bearing BALB/c mouse xenograft model.Together,such a core-matched nanoassembly of pure photosensitizer provides a new strategy for the development of imaging-guided theragnostic nanomedicines. | Shenwu Zhang Yuequan Wang Zhiqiang Kong Xuanbo Zhang Bingjun Sun Han Yu Qin Chen Cong Luo Jin Sun Zhonggui He | 2021 | Acta Pharmaceutica Sinica B2021,11,11: | 3 |
| 8 | Spatial differences in soybean bioactive components across China and their influence by weather factors显示文摘Bioactive components are partially responsible for the nutritional and health benefits of soybeans. Four major bioactive components: isoflavones, oligosaccharides, phospholipids,and saponins, were quantified in 763 soybean samples collected from widely distributed regions across China from 2010 to 2013. A majority of the tested bioactive components showed generally declining trends from the north(high latitude) to the south(low latitude).A positive relationship between total oligosaccharides(TO) and altitude was observed. Total isoflavones(TI), phospholipids(TP) and TO were negatively correlated with cumulative temperature above or equal to 15 °C(AT15) and mean daily temperature(MDT), but positively correlated with diurnal temperature range(DTR) and hours of sunshine(HS).Total saponins(TS) were negatively correlated with MDT but positively correlated with rainfall(RF), whereas TO were negatively correlated with RF. Path-coefficient analysis showed that, besides genotype differences, temperature and HS during the reproductive period influenced TI and TP contents, while temperature and RF influenced TS and TO. The effects of weather factors on soybean bioactive components in diverse regions of China were characterized. These findings will be helpful in promoting soybean production for functional food purposes. | Wenwen Song Ruping Yang Xiushi Yang Shi Sun Srinivasa Rao Mentreddy Bingjun Jiang Tingting Wu Shiyan Tian Enoch Sapey Cunxiang Wu Wensheng Hou Guixing Ren Tianfu Han | 2018 | The Crop Journal2018,6,6: | 3 |
| 9 | Influence of anchorage length and pretension on the working resistance of rock bolt based on its tensile characteristics显示文摘In coal mining roadway support design,the working resistance of the rock bolt is the key factor affecting its maximum support load.Effective improvement of the working resistance is of great significance to roadway support.Based on the rock bolt’s tensile characteristics and the mining roadway surrounding rock deformation,a mechanical model for calculating the working resistance of the rock bolt was established and solved.Taking the mining roadway of the 17102(3)working face at the Panji No.3 Coal Mine of China as a research site,with a quadrilateral section roadway,the influence of pretension and anchorage length on the working resistance of high-strength and ordinary rock bolts in the middle and corner of the roadway is studied.The results show that when the bolt is in the elastic stage,increasing the pretension and anchorage length can effectively improve the working resistance.When the bolt is in the yield and strain-strengthening stages,increasing the pretension and anchorage length cannot effectively improve the working resistance.The influence of pretension and anchorage length on the ordinary and high-strength bolts is similar.The ordinary bolt’s working resistance is approximately 25 kN less than that of the high-strength bolt.When pretension and anchorage length are considered separately,the best pretensions of the high-strength bolt in the middle of the roadway side and the roadway corner are 41.55 and 104.26 kN,respectively,and the best anchorage lengths are 1.54 and 2.12 m,respectively.The best anchorage length of the ordinary bolt is the same as that of the high-strength bolt,and the best pretension for the ordinary bolt in the middle of the roadway side and at the roadway corner is 33.51 and 85.12 kN,respectively.The research results can provide a theoretical basis for supporting the design of quadrilateral mining roadways. | Jucai Chang Kai He Dongdong Pang Dong Li Chuanming Li Bingjun Sun | 2021 | International Journal of Coal Science & Technology2021,8,6: | 2 |
| 10 | Genomic dissection of widely planted soybean cultivars leads to a new breeding strategy of crops in the post-genomic era显示文摘Soybeans specially the widely planted cultivars have been dramatically improved in agronomic performance and is well adapted to local planting environments after long-time domestication and breeding.Uncovering the unique genomic features of popular cultivars will help to understand how soybean genomes have been modified through breeding.We re-sequenced 134 soybean cultivars that were released and most widely planted over the last century in China.Phylogenetic analyses established that these cultivars comprise two geographically distinct sub-populations:Northeast China (NE) versus the HuangHuai-Hai River Valley and South China (HS).A total of 309 selective regions were identified as being impacted by geographical origins.The HS sub-population exhibited higher genetic diversity and linkage disequilibrium decayed more rapidly compared to the NE sub-population.To study the association between phenotypic differences and geographical origins,we recorded the vegetative period under different growing conditions for two years,and found that clustering based on the phenotypic data was closely correlated with cultivar geographical origin.By iteratively calculating accumulated genetic diversity,we established a platform panel of cultivars and have proposed a novel breeding strategy named 'Potalaization'for selecting and utilizing the platform cultivars that represent the most genetically diversity and the highest available agronomic performance as the 'plateau'for accumulating elite loci and traits,breeding novel widely adapted cultivars,and upgrading breeding technology.In addition to providing new genomic information for the soybean research community,the 'Potalaization'strategy that we devised will also be practical for integrating the conventional and molecular breeding programs of crops in the post-genomic era. | Xinpeng Qi Bingjun Jiang Tingting Wu Shi Sun Caijie Wang Wenwen Song Cunxiang Wu Wensheng Hou Qijian Song Hon-Ming Lam Tianfu Han | 2021 | The Crop Journal2021,9,5: | 1 |
| 11 | Minor change in the length of carbon chain has a great influence on the antitumor effect of paclitaxel-fatty alcohol prodrug nanoassemblies:Small roles,big impacts显示文摘Prodrug-based nanoassembly emerges as a hopeful way for the efficient delivery of antitumor drugs,with carrier-free structure and ultra-high drug loading.Carbon chains are widely used to design self-assembling prodrugs.The impacts of the length of carbon chains on the self-assembly stability,drug delivery efficiency and antitumor effect of prodrugs have not been fully elucidated.Here,three paclitaxel prodrugs were synthesized by conjugating paclitaxel with octanol(C_(8)),decanol(C_(10))or dodecanol(C_(12))through disulfide bond.The three prodrugs could form homogeneous nanoparticles,with over 50%drug loading and redox dual-responsivity.Interestingly,the length extension of carbon chains ameliorates the self-assembly and the colloidal stability of prodrugs,thus improving the drug delivery efficiency.The optimal paclitaxel-dodecanol prodrug nanoassemblies exhibit better antitumor efficacy than Taxol and Abraxane.These findings are meaningful for the rational design of advanced nanomedicines in cancer therapy. | Xin Wang Lingxiao Li Danping Wang Shiyi Zuo Tian Liu Fudan Dong Xuanbo Zhang Zhonggui He Bingjun Sun Jin Sun | 2022 | Nano Research2022,15,4: | 1 |
| 12 | Impact of the amount of PEG on prodrug nanoassemblies for efficient cancer therapy显示文摘PEGylation has been widely used to improve the pharmacokinetic properties of prodrug self-assembled nanoparticles(prodrug-SANPs).However,the impacts of the amount of PEG on the self-assemble stability,cellular uptake,pharmacokinetics,and antitumor efficacy of prodrug-SANPs are still unknown.Herein,selenoether bond bridged docetaxel dimeric prodrug was synthesized as the model prodrug.Five prodrug-SANPs were designed by using different mass ratios of prodrugs to PEG(W_(prodrug)/W_(DSPE-mPEG2000)=10:0,9:1,8:2,7:3 and 6:4),and defined as Pure drug NPs,9:1NPs,8:2NPs,7:3 NPs and 6:4 NPs,respectively.Interestingly,8:2 NPs formed the most compact nanostructure,thus improving the self-assemble stability and pharmacokinetics behavior.In addition,the difference of these prodrug-SANPs in cellular uptake was investigated,and the influence of PEG on cytotoxicity and antitumor efficacy was also clarified in details.The 8:2 NPs exhibited much better antitumor efficacy than other prodrug-SANPs and even commercial product.Our findings demonstrated the pivotal role of the amount of PEG on prodrug-SANPs. | Yaqiao Li Lingxiao Li Qianhui Jin Tian Liu Jin Sun Yongjun Wang Zhijun Yang Zhonggui He Bingjun Sun | 2022 | Asian Journal of Pharmaceutical Sciences2022,17,2: | 1 |
| 13 | Integration of phospholipid-drug complex into self-nanoemulsifying drug delivery system to facilitate oral delivery of paclitaxel显示文摘Self-nanoemulsifying drug delivery system(SNEDDS) has emerged as a promising platform to improve oral absorption of drugs with poor solubility and low permeability. However,large polarity molecules with insufficient lipid solubility,such as paclitaxel(PTX),would suffer from inferior formulation of SNEDDS due to poor compatibility. Herein,phospholipid-drug complex(PLDC) and SNEDDS were integrated into one system to facilitate oral delivery of PTX. First,PTX was formulated into PLDC in response to its inferior physicochemical properties. Then,the prepared PLDC was further formulated into SNEDDS by integrating these two drug delivery technologies into one system(PLDC-SNEDDS). After PLDC-SNEDDS dispersed in aqueous medium,nanoemulsion was formed immediately with an average particle size of ~30 nm. Furthermore,the nanomulsion of PLDC-SNEDDS showed good colloidal stability in both HCl solution(0.1 mol/l,p H 1.0) and phosphate buffer solution(PBS,p H 6.8). In vivo,PTX-PLDC-SNEDDS showed distinct advantages in terms of oral absorption efficiency,with a3.42-fold and 2.13-fold higher bioavailability than PTX-PLDC and PTX solution,respectively.Our results suggest that the integration of PLDC into SNEDDS could be utilized to facilitate the oral delivery of hydrophobic drugs with large polarity. | Dawei Ding Bingjun Sun Weiping Cui Qin Chen Xuanbo Zhang Haotian Zhang Zhonggui He Jin Sun Cong Luo | 2019 | Asian Journal of Pharmaceutical Sciences2019,14,5: | 1 |
| 14 | Precisely engineering a dual-drug cooperative nanoassembly for proteasome inhibition-potentiated photodynamic therapy显示文摘Photodynamic therapy(PDT) has been widely investigated for cancer therapy. The intracellular accumulation of reactive oxygen species(ROS)-damaged protein facilitates tumor cell apoptosis. However, there is growing evidence that the ubiquitin-proteasome pathway(UPP) significantly impedes PDT by preventing the enrichment of ROS-damaged proteins in tumor cells. To tackle this challenge, we report a facile dual-drug nanoassembly based on the discovery of an interesting co-assembly of bortezomib(BTZ, a proteasome inhibitor) and pyropheophorbide a(PPa) for proteasome inhibition-mediated PDT sensitization.The precisely engineered nanoassembly with the optimal dose ratio of BTZ and PPa demonstrates multiple advantages, including simple fabrication, high drug co-loading efficiency, flexible dose adjustment,good colloidal stability, long systemic circulation, favorable tumor-specific accumulation, as well as significant enrichment of ROS-damaged proteins in tumor cells. As a result, the cooperative nanoassembly exhibits potent synergistic antitumor activity in vivo. This study provides a novel dual-drug engineering modality for multimodal cancer treatment. | Fujun Yang Qingyu Ji Rui Liao Shumeng Li Yuequan Wang Xuanbo Zhang Shenwu Zhang Haotian Zhang Qiming Kan Jin Sun Zhonggui He Bingjun Sun Cong Luo | 2022 | Chinese Chemical Letters2022,33,4: | 1 |
| 15 | Structurally defined tandem-responsive nanoassemblies composed of dipeptide-based photosensitive derivatives and hypoxia-activated camptothecin prodrugs against primary and metastatic breast tumors显示文摘Substantial progress in the use of chemo-photodynamic nano-drug delivery systems(nanoDDS) for the treatment of the malignant breast cancer has been achieved. The inability to customize precise nanostructures, however, has limited the therapeutic efficacy of the prepared nano-DDS to date. Here,we report a structurally defined tandem-responsive chemo-photosensitive co-nanoassembly to eliminate primary breast tumor and prevent lung metastasis. This both-in-one co-nanoassembly is prepared by assembling a biocompatible photosensitive derivative(pheophorbide-diphenylalanine peptide, PPADA) with a hypoxia-activated camptothecin(CPT) prodrug [(4-nitrophenyl) formate camptothecin, NCPT]. According to computational simulations, the co-assembly nanostructure is not the classical core-shell type, but consists of many small microphase regions. Upon exposure to a 660 nm laser,PPA-DA induce high levels of ROS production to effectively achieve the apoptosis of normoxic cancer cells. Subsequently, the hypoxia-activated N-CPT and CPT spatially penetrate deep into the hypoxic region of the tumor and suppress hypoxia-induced tumor metastasis. Benefiting from the rational design of the chemo-photodynamic both-in-one nano-DDS, these nanomedicines exhibit a promising potential in the inhibition of difficult-to-treat breast tumor metastasis in patients with breast cancer. | Mengchi Sun Hailun Jiang Tian Liu Xiao Tan Qikun Jiang Bingjun Sun Yulong Zheng Gang Wang Yang Wang Maosheng Cheng Zhonggui He Jin Sun | 2022 | Acta Pharmaceutica Sinica B2022,12,2: | 1 |
| 16 | Iron-doxorubicin prodrug loaded liposome nanogenerator programs multimodal ferroptosis for efficient cancer therapy显示文摘Ferroptosis is a new mode of cell death,which can be induced by Fenton reactionmediated lipid peroxidation.However,the insufficient H2O2 and high GSH in tumor cells restrict the efficiency of Fenton reaction-dependent ferroptosis.Herein,a self-supplying lipid peroxide nanoreactor was developed to co-delivery of doxorubicin(DOX),iron and unsaturated lipid for efficient ferroptosis.By leveraging the coordination effect between DOX and Fe3+,trisulfide bond-bridged DOX dimeric prodrug was actively loaded into the core of the unsaturated lipids-rich liposome via iron ion gradient method.First,Fe3+could react with the overexpressed GSH in tumor cells,inducing the GSH depletion and Fe2+generation.Second,the cleavage of trisulfide bond could also consume GSH,and the released DOX induces the generation of H2O2,which would react with the generated Fe2+in step one to induce efficient Fenton reaction-dependent ferroptosis.Third,the formed Fe3+/Fe2+couple could directly catalyze peroxidation of unsaturated lipids to boost Fenton reaction-independent ferroptosis.This iron-prodrug liposome nanoreactor precisely programs multimodal ferroptosis by integrating GSH depletion,ROS generation and lipid peroxidation,providing new sights for efficient cancer therapy. | Yinxian Yang Shiyi Zuo Linxiao Li Xiao Kuang Jinbo Li Bingjun Sun Shujun Wang Zhonggui He Jin Sun | 2021 | Asian Journal of Pharmaceutical Sciences2021,16,6: | 1 |
| 17 | Analysis of wild vascular plant resources and diversity in Taibai Mountains of Qinling area,Shaanxi Province显示文摘Taibai Mountains,located at the northern foot of the Qinling Mountains,are composed of the Yuan Taibai Mountain(also known as East Taibai Mountain),Aoshan Mountain(also known as West Taibai Mountain)and their connection part.With its complex geographical and climatic conditions,Taibai Mountains are extremely rich in wild plant resources.Based on field investigation,literature review and specimen identification,wild vascular plants resources and their diversity in Taibai Mountains were studied by the sixth Traditional Chinese Medicine(TCM)Resources Scientific Expedition Team of Shenyang Pharmaceutical University.222 species of vascular plants belonging to 163 genera and 63 families were collected during July 2012 in this area,and most of the plants are angiosperms.The families with more species are Liliaceae,Ranunculaceae,Asteraceae,Rosaceae,and Saxifragaceae,and the dominant genus are Aconitum,Sedum,Eleutherococcus,Pedicularis,Polygonatum,and Patrinia.In terms of life form,perennial herbs are the main species,accounting for 72.97%of the total species,with others being some annual(or biennial)herbs,shrubs and lianas.Among all the collected vascular plants,170 species of them are medicinal vascular plants,accounting for 76.58%of the total.Most of the medicinal parts are roots and rhizomes,followed by the whole plants.Finally,on the basis of investigation and study,some suggestions are put forward to strengthen the protection and utilization of plant resources in Taibai Mountains. | Bingjun Sun Qing Wang Minli Ruan Anhua Wang Jingming Jia | 2023 | Asian Journal of Traditional Medicines2023,18,6: | 0 |
| 18 | The effect of lengths of branched-chain fatty alcohols on the efficacy and safety of docetaxel-prodrug nanoassemblies显示文摘The self-assembly prodrugs are usually consisted of drug modules,activation modules,and assembly modules.Keeping the balance between efficacy and safety by selecting suitable modules remains a challenge for developing prodrug nanoassemblies.This study designed four docetaxel(DTX)prodrugs using disulfide bonds as activation modules and different lengths of branched-chain fatty alcohols as assembly modules(C_(16),C_(18),C_(20),and C_(24)).The lengths of the assembly modules determined the self-assembly ability of prodrugs and affected the activation modules’sensitivity.The extension of the carbon chains improved the prodrugs’self-assembly ability and pharmacokinetic behavior while reducing the cytotoxicity and increased cumulative toxicity.The use of C_(20) can balance efficacy and safety.These results provide a great reference for the rational design of prodrug nanoassemblies. | Shuo Wang Tian Liu Yuetong Huang Chaoying Du Danping Wang Xiyan Wang Qingzhi Lv Zhonggui He Yinglei Zhai Bingjun Sun Jin Sun | 2024 | Acta Pharmaceutica Sinica B2024,14,3: | 0 |
| 19 | A telomere-to-telomere genome assembly of Zhonghuang 13,a widely-grown soybean variety from the original center of Glycine max显示文摘Soybean(Glycine max)stands as a globally significant agricultural crop,and the comprehensive assembly of its genome is of paramount importance for unraveling its biological characteristics and evolutionary history.Nevertheless,previous soybean genome assemblies have harbored gaps and incompleteness,which have constrained in-depth investigations into soybean.Here,we present Telomere-to-Telomere(T2T)assembly of the Chinese soybean cultivar Zhonghuang 13(ZH13)genome,termed ZH13-T2T,utilizing PacBio Hifi and ONT ultralong reads.We employed a multi-assembler approach,integrating Hifiasm,NextDenovo,and Canu,to minimize biases and enhance assembly accuracy.The assembly spans 1,015,024,879 bp,effectively resolving all 393 gaps that previously plagued the reference genome.Our annotation efforts identified 50,564 high-confidence protein-coding genes,707 of which are novel.ZH13-T2T revealed longer chromosomes,421 not-aligned regions(NARs),112 structure variations(SVs),and a substantial expansion of repetitive element compared to earlier assemblies.Specifically,we identified 25.67 Mb of tandem repeats,an enrichment of 5S and 48S rDNAs,and characterized their genotypic diversity.In summary,we deliver the first complete Chinese soybean cultivar T2T genome.The comprehensive annotation,along with precise centromere and telomere characterization,as well as insights into structural variations,further enhance our understanding of soybean genetics and evolution. | Anqi Zhang Tangchao Kong Baiquan Sun Shizheng Qiu Jiahe Guo Shuyong Ruan Yu Guo Jirui Guo Zhishuai Zhang Yue Liu Zheng Hu Tao Jiang Yadong Liu Shuqi Cao Shi Sun Tingting Wu Huilong Hong Bingjun Jiang Maoxiang Yang Xiangyu Yao Yang Hu Bo Liu Tianfu Han Yadong Wang | 2024 | The Crop Journal2024,12,1: | 0 |
| 20 | Cancer-specific calcium nanoregulator suppressing the generation and circulation of circulating tumor cell clusters for enhanced anti-metastasis combinational chemotherapy显示文摘Tumor metastasis is responsible for chemotherapeutic failure and cancer-related death.Moreover,circulating tumor cell(CTC)clusters play a pivotal role in tumor metastasis.Herein,we develop cancer-specific calcium nanoregulators to suppress the generation and circulation of CTC clusters by cancer membrane-coated digoxin(DIG)and doxorubicin(DOX)co-encapsulated PLGA nanoparticles(CPDDs).CPDDs could precisely target the homologous primary tumor cells and CTC clusters in blood and lymphatic circulation.Intriguingly,CPDDs induce the accumulation of intracellular Ca^(2+) by inhibiting Na^(+)/K^(+)-ATPase,which help restrain cellecell junctions to disaggregate CTC clusters.Meanwhile,CPDDs suppress the epithelialemesenchymal transition(EMT)process,resulting in inhibiting tumor cells escape from the primary site.Moreover,the combination of DOX and DIG at a mass ratio of 5:1 synergistically induces the apoptosis of tumor cells.In vitro and in vivo results demonstrate that CPDDs not only effectively inhibit the generation and circulation of CTC clusters,but also precisely target and eliminate primary tumors.Our findings present a novel approach for anti-metastasis combinational chemotherapy. | Dan Li Yingli Wang Chang Li Qiu Wang Bingjun Sun Haotian Zhang Zhonggui He Jin Sun | 2021 | Acta Pharmaceutica Sinica B2021,11,10: | 0 |
