| 1 | Blends of hydrophobic and swelling agents in the swelling layer in the preparation of delayed-release pellets of a hydrophilic drug with low MW: Physicochemical characterizations and in-vivo evaluations显示文摘In this study,a hydrophobic material,ethylcellulose,which was used as its aqueous suspension Surelease^(®),was combined with a swelling agent as the swelling layer to prepare delayed-release pellets for Danshensu,which is a hydrophilic drug with low MW.A rupturable,delayed-release pellet consists of a drug core,a swelling layer containing a swelling agent(cross-linked sodium carboxymethyl cellulose)with a hydrophobic agent(Surelease^(®)),and a controlled layer composed by an insoluble,water-permeable polymeric coating(aqueous ethylcellulose dispersions)was developed in a fluidised bed.Results showed that blending Surelease^(®)into the swelling layer could effectively extend the release of Danshensu from the pellets,which may be attributed to the slowed swelling rate by reduction of water penetration and improvement of mechanical integrity of the swelling layer.Drug in the delayed pellets showed sustained release in beagle dogs after oral administration with comparable in-vivo exposure to the uncoated drug pellets.In conclusion,blends of hydrophobic and swelling agents in the swelling layer in doublemembrane pellets could achieve a delayed drug-release profile in vitro,as well as delayed and sustained absorption in vivo for highly soluble,low-MW drug.The present study highlighted the potential use of a delayed-release system for other hydrophilic,low-MW drugs to meet the formulation requirements for chronopharmacological diseases. | Chang You Xuedan Liang Jiabei Sun Lin Sun Yitao Wang Tianyuan Fan Ying Zheng | 2014 | Asian Journal of Pharmaceutical Sciences2014，9，4： | 2 |

| 3 | Facile synthesis of Er^(3+)/Tm^(3+)co-doped magnetic/luminescent nanosystems for possible bioimaging and therapy applications显示文摘Manganese-zinc ferrite is a kind of very important magnetic ferrite material.The properties of wide absorption band,sensitivity to ultraviolet(UV)light and tumor H_(2)O_(2) promise it to be possibly used as a photothermal therapy(PTT),photodynamic therapy(PDT)and chemodynamic therapy(CDT)agent.Based on the unique advantages of rare-earth doped nanoparticles,an Er^(3+),Tm^(3+)co-doped upconversion-mediated nanosystem with manganese-zinc ferrite shell(named as UCNPS@M)was developed through a facile thermal co-decomposition method.The final nanosystems were surface-modified by using dopamine hydrochloride(DA)in order to warrant good biocompatibility(named as UCNPS@M@DA).Under irradiation of near-infrared(NIR)light,UCNPS emit both ultraviolet and visible light.The UV light is mostly abso rbed by manga nese-zinc ferrite shell to produce reactive oxygen species(ROS),which is essential to the potential PDT and CDT effect of nanosystems,and at the same time,Mn_(0.5)Zn_(0.5)Fe2O_(4) can further react with H_(2)O_(2) to promote the efficiency of OH-generation.It is expected that UCNPS@M@DA can act as upconversion luminescence imaging guidance due to the visible emission from UCNPS.In addition,the energy absorbed by the nanosystems can be transferred to heat to realize photothermal effect.Moreover,UCNPS@M@DA was successfully applied as a T_(1)/T_(2)-weighted magnetic resonance imaging(MRI)contrast agent due to the existence of Gd,Mn,and Fe elements.In light of the upconversion luminescence(UCL)imaging from the UCNPS as well as potential PTT,PDT,CDT effect mentioned above,this work provides a possibility to realize cancer multi-model bioimaging guided treatment by using an all-in-one diagnosis and therapy nanosystem through a simple yet powerful strategy. | Hongyu Liu Jiabei Li Pengfei Hu Songqiang Sun Liyi Shi Lining Sun | 2022 | Journal of Rare Earths2022，40，1： | 1 |

| 5 | LAL test and RPT for endotoxin detection of CPT-11/DSPE-mPEG_(2000) nanoformulation: What if traditional methods are not applicable?显示文摘Endotoxin detection is an important step in drug characterization. Herein we found that a chemotherapeutic drug nanoformulation composed of irinotecan hydrochloride(CPT-11) and an amphiphilic molecule DSPE-mPEG_(2000) can interfere with the limulus amebocyte lysate assay(LAL). Furthermore, the rabbit pyrogen test(RPT) results indicated that at a relatively high dosage, the drug irinotecan hydrochloride can induce a hypothermia effect which may render the RPT results ambiguous in determination of the safety of the drug formulation.Our findings demonstrate limitations of endotoxin detection in micellar drugs,and call for the necessity of developing reliable endotoxin detection methods that can overcome the interference of nanomaterials in order to better ensure the drug safety of patients in future pharmaceutical drug development. | Yanan Jin Juanjuan Jia Chan Li Jianqi Xue Jiabei Sun Kaiyuan Wang Yaling Gan Jing Xu Yaqin Shi Xingjie Liang | 2018 | Asian Journal of Pharmaceutical Sciences2018，13，3： | 0 |
| 6 | Global profiling of O-GlcNAcylated and/or phosphorylated proteins in hepatoblastoma显示文摘O-linked-β-N-acetylglucosamine(O-GlcNAc)glycosylation(O-GlcNAcylation)and phosphorylation are critical posttranslational modifications that are involved in regulating the functions of proteins involved in tumorigenesis and the development of various solid tumors.However,a detailed characterization of the patterns of these modifications at the peptide or protein level in hepatoblastoma(HB),a highly malignant primary hepatic tumor with an extremely low incidence in children,has not been performed.Here,we examined O-GlcNAc-modified or phospho-modified peptides and proteins in HB through quantitative proteomic analysis of HB tissues and paired normal liver tissues.Our results identified 114 O-GlcNAcylated peptides belonging to 78 proteins and 3494 phosphorylated peptides in 2088 proteins.Interestingly,41 proteins were modified by both O-GlcNAcylation and phosphorylation.These proteins are involved in multiple molecular and cellular processes,including chromatin remodeling,transcription,translation,transportation,and organelle organization.In addition,we verified the accuracy of the proteomics results and found a competitive inhibitory effect between O-GlcNAcylation and phosphorylation of HSPB1.Further,O-GlcNAcylation modification of HSPB1 promoted proliferation and enhanced the chemotherapeutic resistance of HB cell lines in vitro.Collectively,our research suggests that O-GlcNAc-modified and/or phospho-modified proteins may play a crucial role in the pathogenesis of HB. | Hang Song Ji Ma Zhixuan Bian Shuhua Chen Jiabei Zhu Jing Wang Nan Huang Minzhi Yin Fenyong Sun Min Xu Qiuhui Pan | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 0 |
| 7 | The Yin and Yang of the protein corona on the delivery journey of nanoparticles显示文摘Nanoparticles-based drug delivery systems have attracted significant attention in biomedical fields because they can deliver loaded cargoes to the target site in a controlled manner.However,tremendous challenges must still be overcome to reach the expected targeting and therapeutic efficacy in vivo.These challenges mainly arise because the interaction between nanoparticles and biological systems is complex and dynamic and is influenced by the physicochemical properties of the nanoparticles and the heterogeneity of biological systems.Importantly,once the nanoparticles are injected into the blood,a protein corona will inevitably form on the surface.The protein corona creates a new biological identity which plays a vital role in mediating the bio–nano interaction and determining the ultimate results.Thus,it is essential to understand how the protein corona affects the delivery journey of nanoparticles in vivo and what we can do to exploit the protein corona for better delivery efficiency.In this review,we first summarize the fundamental impact of the protein corona on the delivery journey of nanoparticles.Next,we emphasize the strategies that have been developed for tailoring and exploiting the protein corona to improve the transportation behavior of nanoparticles in vivo.Finally,we highlight what we need to do as a next step towards better understanding and exploitation of the protein corona.We hope these insights into the“Yin and Yang”effect of the protein corona will have profound implications for understanding the role of the protein corona in a wide range of nanoparticles. | Yi-Feng Wang Yaxin Zhou JiaBei Sun Xiaotong Wang Yaru Jia Kun Ge Yan Yan Kenneth A.Dawson Shutao Guo Jinchao Zhang Xing-Jie Liang | 2023 | Nano Research2023，16，1： | 0 |
