| 1 | Cell Membrane-camouflaged Multi-functional Dendritic Large Pore Mesoporous Silica Nanoparticles for Combined Photothermal Therapy and Radiotherapy of Cancer显示文摘Combining photothermal therapy and radiotherapy(PTT-RT) with reducing tumor hypoxia acts as an important antitumor modality. However, it is a great challenge to realize photothermal therapy, radiotherapy and exogenous oxygen supply in one nanosystem. To realize a combination of the three functions, we fabricated a red blood cell membrane(RBCm)-camouflaged, red blood cell content(RBCc) and the copper sulfide(CuS) co-loaded dendritic large pore mesoporous silica nanoparticle(DLMSN/CuS/RBCc/ RBCm). The cell membrane coating endowed the nanoparticles with good stability in the physiological environment, and CuS allowed the nanoparticle exhibiting good photothermal and radiosensitization properties. RBCc loaded nanoparticle DLMSN/CuS/RBCc enhanced superior anti-tumor effect than DLMSN/CuS during combined PTT-RT therapy because the introduction of RBCc increased the exogenous oxygen supply. The in vitro study further demonstrated that the combination of photothermal therapy and radiotherapy induced superior antitumor efficacy than single therapy. Our work thus presents a unique multifunctional nanoscale platform favorable for combined PTT and RT. | WU Liting XIN Yujia GUO Zhaoyang GAO Wei ZHU Yanpeng WANG Yinsong RAN Ruixue YANG Xiaoying | 2022 | Chemical Research in Chinese Universities2022，38，2： | 1 |
| 2 | Strontium-incorporated bioceramic scaffolds for enhanced osteoporosis bone regeneration显示文摘The restoration of bone defects caused by osteoporosis remains a challenge for surgeons.Strontium ranelate has been applied in preventative treatment approaches due to the biological functions of the trace element strontium(Sr).In this study,we aimed to fabricate bioactive scaffolds through Sr incorporation based on our previously developed modified amino-functional mesoporous bioactive glass(MBG)and to systematically investigate the bioactivity of the resulting scaffold in vitro and in vivo in an osteoporotic rat model.The results suggested that Sr-incorporated amino-functional MBG scaffolds possessed favorable biocompatibility.Moreover,with the incorporation of Sr,osteogenic and angiogenic capacities were upregulated in vitro.The in vivo results showed that the Sr-incorporated amino-functional MBG scaffolds achieved better bone regeneration and vessel formation.Furthermore,bioinformatics analysis indicated that the Sr-incorporated amino-functional MBG scaffolds could reduce reactive oxygen species levels in bone marrow mesenchymal stem cells in the osteoporotic model by activating the cAMP/PKA signaling pathway,thus playing an anti-osteoporosis role while promoting osteogenesis.This study demonstrated the feasibility of incorporating trace elements into scaffolds and provided new insights into biomaterial design for facilitating bone regeneration in the treatment of osteoporosis. | Qianju Wu Longwei Hu Ran Yan Junfeng Shi Hao Gu Yuwei Deng Ruixue Jiang Jin Wen Xinquan Jiang | 2022 | Bone Research2022，10，4： | 1 |
| 3 | Establishment and assessment of rodent models of medication-related osteonecrosis of the jaw(MRONJ)显示文摘Medication-related osteonecrosis of the jaw(MRONJ)is primarily associated with administering antiresorptive or antiangiogenic drugs.Despite significant research on MRONJ,its pathogenesis and effective treatments are still not fully understood.Animal models can be used to simulate the pathophysiological features of MRONJ,serving as standardized in vivo experimental platforms to explore the pathogenesis and therapies of MRONJ.Rodent models exhibit excellent effectiveness and high reproducibility in mimicking human MRONJ,but classical methods cannot achieve a complete replica of the pathogenesis of MRONJ.Modified rodent models have been reported with improvements for better mimicking of MRONJ onset in clinic.This review summarizes representative classical and modified rodent models of MRONJ created through various combinations of systemic drug induction and local stimulation and discusses their effectiveness and efficiency.Currently,there is a lack of a unified assessment system for MRONJ models,which hinders a standard definition of MRONJ-like lesions in rodents.Therefore,this review comprehensively summarizes assessment systems based on published peer-review articles,including new approaches in gross observation,histological assessments,radiographic assessments,and serological assessments.This review can serve as a reference for model establishment and evaluation in future preclinical studies on MRONJ. | Ran Yan Ruixue Jiang Longwei Hu Yuwei Deng Jin Wen Xinquan Jiang | 2022 | International Journal of Oral Science2022，14，3： | 1 |
| 4 | Development of an LC–MS/MS method for the quantitation of deoxyglycychloxazol in rat plasma and its application in pharmacokinetic study显示文摘Deoxyglycychloxazol(TY501) is a glycyrrhetinic acid derivative which exhibits high anti-inflammatory activity and reduced pseudoaldosteronism compared to glycyrrhetinic acid.In this study,a sensitive and rapid liquid chromatography–tandem mass spectrometry(LC–MS/MS) method was established for the quantitation of TY501 in rat plasma.Plasma samples were treated by precipitating protein with methanol and supernatants were separated by a Symmetry C_8 column with the mobile phase consisting of methanol and 10 m M ammonium formate(containing 0.1% of formic acid)(90:10,v/v).The selected reaction monitoring(SRM) transitions were performed at m/z 647.4-191.2 for TY501 and m/z 473.3-143.3 for astragaloside aglycone(IS) in the positive ion mode with atmospheric pressure chemical ionization(APCI) source.Calibration curve was linear over the concentration range of 5–5000 ng/m L.The lower limit of quantification was 5 ng/m L.The mean recovery was over 88%.The intra- and inter-day precisions were lower than 6.0% and 12.8%,respectively,and the accuracy was within 7 1.3%.TY501 was stable under usual storage conditions and handling procedure.The validated method has been successfully applied to a pharmacokinetic study after oral administration of TY501 to rats at a dosage of 10 mg/kg. | Rongshan Li Ruixue Ran Quansheng Li Yurong Huang Yuan Gu Duanyun Si | 2016 | Journal of Pharmaceutical Analysis2016，6，3： | 0 |
