| 1 | Mesoporous silica nanoparticles for drug and gene delivery显示文摘Mesoporous silica nanoparticles(MSNs) are attracting increasing interest for potential biomedical applications. With tailored mesoporous structure, huge surface area and pore volume,selective surface functionality, as well as morphology control, MSNs exhibit high loading capacity for therapeutic agents and controlled release properties if modified with stimuli-responsive groups, polymers or proteins. In this review article, the applications of MSNs in pharmaceutics to improve drug bioavailability, reduce drug toxicity, and deliver with cellular targetability are summarized. Particularly,the exciting progress in the development of MSNs-based effective delivery systems for poorly soluble drugs, anticancer agents, and therapeutic genes are highlighted. | Yixian Zhou Guilan Quan Qiaoli Wu Xiaoxu Zhang Boyi Niua Biyuan Wu Ying Huang Xin Pan Chuanbin Wu | 2018 | Acta Pharmaceutica Sinica B2018，8，2： | 31 |
| 2 | BMP-IHH-mediated interplay between mesenchymal stem cells and osteoclasts supports calvarial bone homeostasis and repair显示文摘Calvarial bones are connected by fibrous sutures. These sutures provide a niche environment that includes mesenchymal stem cells(MSCs), osteoblasts, and osteoclasts, which help maintain calvarial bone homeostasis and repair. Abnormal function of osteogenic cells or diminished MSCs within the cranial suture can lead to skull defects, such as craniosynostosis. Despite the important function of each of these cell types within the cranial suture, we have limited knowledge about the role that crosstalk between them may play in regulating calvarial bone homeostasis and injury repair. Here we show that suture MSCs give rise to osteoprogenitors that show active bone morphogenetic protein(BMP) signalling and depend on BMP-mediated Indian hedgehog(IHH) signalling to balance osteogenesis and osteoclastogenesis activity. IHH signalling and receptor activator of nuclear factor kappa-Β ligand(RANKL) may function synergistically to promote the differentiation and resorption activity of osteoclasts. Loss of Bmpr1a in MSCs leads to downregulation of hedgehog(Hh) signalling and diminished cranial sutures. Significantly, activation of Hh signalling partially restores suture morphology in Bmpr1a mutant mice, suggesting the functional importance of BMP-mediated Hh signalling in regulating suture tissue homeostasis. Furthermore, there is an increased number of CD200+ cells in Bmpr1a mutant mice, which may also contribute to the inhibited osteoclast activity in the sutures of mutant mice. Finally, suture MSCs require BMPmediated Hh signalling during the repair of calvarial bone defects after injury. Collectively, our studies reveal the molecular and cellular mechanisms governing cell–cell interactions within the cranial suture that regulate calvarial bone homeostasis and repair. | Yuxing Guo Yuan Yuan Ling Wu Thach-Vu Ho Junjun Jing Hideki Sugii Jingyuan Li Xia Han Jifan Feng Chuanbin Guo Yang Chai | 2018 | Bone Research2018，6，4： | 12 |
| 3 | Synergistic immunoreaction of acupuncture-like dissolving microneedles containing thymopentin at acupoints in immune-suppressed rats显示文摘Dissolving microneedles carried drug molecules can effectively penetrate the stratum corneum of skin to improve the transdermal drug delivery. The traditional Chinese medicine acupuncture is based on the needle stimulation at a specific location(acupoint) to generate and transmit biochemical and physiological signals which alter the pathophysiological state of patients. However, the pain associated with conventional acupuncture needles and the requirement of highly trained professionals limit the development of acupuncture in non-Asian countries. The purpose of this study is to investigate whether the dissolving microneedles can be utilized as a self-administered painless replacement for acupuncture and locally released drug molecules can achieve expected therapeutic outcomes. Immunosuppressive rats were treated with acupuncture at Zusanli(ST36) acupoint using microneedles containing thymopentin.The immune functions and psychological mood of the immunosuppressed animals were examined. The proliferation of splenocytes was examined by CCK-8 assay. CD4 and CD8 expression patterns in spleen cells were detected by flow cytometry. The current study showed that use of either microneedles containing thymopentin or conventional acupuncture both resulted in immune cell proliferation, which was confirmed by flow cytometry. Furthermore, either conventional acupuncture or microneedles were able to effectively mitigate the anxiety caused by immune-suppression when applied on the ST36. | Qian Zhang Chuncao Xu Shiqi Lin Huanbin Zhou Gangtao Yao Hu Liu Lili Wang Xin Pan Guilan Quan Chuanbin Wu | 2018 | Acta Pharmaceutica Sinica B2018，8，3： | 9 |
| 4 | Influence of physical properties of carrier on the performance of dry powder inhalers显示文摘Dry powder inhalers(DPIs) offer distinct advantages as a means of pulmonary drug delivery and have attracted much attention in the field of pharmaceutical science. DPIs commonly contain micronized drug particles which, because of their cohesiveness and strong propensity to aggregate, have poor aerosolization performance. Thus carriers with a larger particle size are added to address this problem. However, the performance of DPIs is profoundly influenced by the physical properties of the carrier, particularly their particle size, morphology/shape and surface roughness. Because these factors are interdependent, it is difficult to completely understand how they individually influence DPI performance.The purpose of this review is to summarize and illuminate how these factors affect drug–carrier interaction and influence the performance of DPIs. | Tingting Peng Shiqi Lin Boyi Niu Xinyi Wang Ying Huang Xuejuan Zhang Ge Li Xin Pan Chuanbin Wu | 2016 | Acta Pharmaceutica Sinica B2016，6，4： | 8 |
| 5 | Bilayer dissolving microneedle array containing 5-fluorouracil and triamcinolone with biphasic release profile for hypertrophic scar therapy显示文摘Hypertrophic scar(HS)is an undesirable skin abnormality following deep burns or operations.Although intralesional multi-injection with the suspension of triamcinolone acetonide(TA)and 5-fluorouracil(5-Fu)has exhibited great promise to HS treatment in clinical,the difference of metabolic behavior between TA and 5-Fu remarkably compromised the treatment efficacy.Besides,the traditional injection with great pain is highly dependent on the skill of the experts,which results in poor compliance.Herein,a bilayer dissolving microneedle(BMN)containing TA and 5-Fu(TA-5-Fu-BMN)with biphasic release profile was designed for HS therapy.Equipped with several micro-scale needle tips,the BMN could be self-pressed into the HS with uniform drug distribution and less pain.Both in vitro permeation and in vivo HS retention tests revealed that TA and 5-Fu could coexist in the scar tissue for a sufficient time period due to the well-designed biphasic release property.Subsequently,the rabbit ear HS model was established to assess therapeutic efficacy.The histological analysis showed that TA-5-Fu-BMN could significantly reduce abnormal fibroblast proliferation and collagen fiber deposition.It was also found that the value of scar elevation index was ameliorated to a basal level,together with the downregulation of mRNA and protein expression of Collagen I(Col I)and transforming growth factor-β1(TGF-β1)after application of TA-5-Fu-BMN.In conclusion,the BMN with biphasic release profiles could serve as a potential strategy for HS treatment providing both convenient administrations as well as controlled drug release behavior. | Beibei Yang Yating Dong Yifeng Shen Ailin Hou Guilan Quan Xin Pan Chuanbin Wu | 2021 | Bioactive Materials2021，6，8： | 8 |
| 6 | Development of composite PLGA microspheres containing exenatide-encapsulated lecithin nanoparticles for sustained drug release显示文摘This study aimed to prepare poly(D, L-lactic-co-glycolic acid) microspheres(PLGA-Ms)by a modified solid-in-oil-in-water(S/O/W) multi-emulsion technique in order to achieve sustained release with reduced initial burst and maintain efficient drug concentration for a prolonged period of time. Composite PLGA microspheres containing exenatideencapsulated lecithin nanoparticles(Ex-NPs-PLGA-Ms) were obtained by initial fabrication of exenatide-loaded lecithin nanoparticles(Ex-NPs) via the alcohol injection method,followed by encapsulation of Ex-NPs into PLGA microspheres. Compared to Ms prepared by the conventional water-in-oil-in-water(W/O/W) technique(Ex-PLGA-Ms), Ex-NPs-PLGAMs showed a more uniform particle size distribution, reduced initial burst release, and sustained release for over 60 d in vitro. Cytotoxicity studies showed that Ms prepared by both techniques had superior biocompatibility without causing any detectable cytotoxicity.In pharmacokinetic studies, the effective drug concentration was maintained for over 30 d following a single subcutaneous injection of two types of Ms formulation in rats, potentially prolonging the therapeutic action of Ex. In addition, administration of Ex-NPs-PLGA-Ms resulted in a more smooth plasma concentration-time profile with a higher area under the curve(AUC) compared to that of Ex-PLGA-Ms. Overall, Ex-NPs-PLGA-Ms prepared by the novel S/O/W method could be a promising sustained drug release system with reduced initial burst release and prolonged therapeutic efficacy. | Ni Dong Chune Zhu Junhuang Jiang Di Huang Xing Li Guilan Quan Yang Liu Wen Tan Xin Pan Chuanbin Wu | 2020 | Asian Journal of Pharmaceutical Sciences2020，15，3： | 7 |
| 7 | Comparative pharmacokinetics of tetramethylpyrazine phosphate in rat plasma and extracellular fluid of brain after intranasal,intragastric and intravenous administration显示文摘The purpose of this study was to compare the pharmacokinetic profiles of tetramethylpyrazine phosphate(TMPP)in plasma and extracellular fluid of the cerebral cortex of rats via three delivery routes:intranasal(i.n.),intragastric(i.g.)and intravenous(i.v.)administration.After i.n.,i.g.and i.v.administration of a single-dose at 10 mg/kg,cerebral cortex dialysates and plasma samples drawn from the carotid artery were collected at timed intervals.The concentration of TMPP in the samples was analyzed by HPLC.The area under the concentration-time curve(AUC)and the ratio of the AUCbrain to the AUCplasma(drug targeting efficiency,DTE)was calculated to evaluate the brain targeting efficiency of the drug via these different routes of administration.After i.n.administration,TMPP was rapidly absorbed to reach its peak plasma concentration within 5 min and showed a delayed uptake into cerebral cortex(t_(max)=15 min).The ratio of the AUCbrain dialysates value between i.n.route and i.v.injection was 0.68,which was greater than that obtained after i.g.administration(0.43).The systemic bioavailability obtained with i.n.administration was greater than that obtained by the i.g.route(86.33%vs.50.39%),whereas the DTE of the nasal route was 78.89%,close to that of oral administration(85.69%).These results indicate that TMPP is rapidly absorbed from the nasal mucosa into the systemic circulation,and then crosses the blood-brain barrier(BBB)to reach the cerebral cortex.Intranasal administration of TMPP could be a promising alternative to intravenous and oral approaches. | Dongmei Meng Haoyang Lu Shanshan Huang Minyan Wei Pingtian Ding Xianglin Xiao Yuehong Xu Chuanbin Wu | 2014 | Acta Pharmaceutica Sinica B2014，4，1： | 5 |
| 8 | TPGS/hyaluronic acid dual-functionalized PLGA nanoparticles delivered through dissolving microneedles for markedly improved chemo-photothermal combined therapy of superficial tumor显示文摘Nanoparticles(NPs)have shown potential in cancer therapy,while a single administration conferring a satisfactory outcome is still unavailable.To address this issue,the dissolving microneedles(DMNs)were developed to locally deliver functionalized NPs with combined chemotherapy and photothermal therapy(PTT).α-Tocopheryl polyethylene glycol succinate(TPGS)/hyaluronic acid(HA)dualfunctionalized PLGA NPs(HD10 NPs)were fabricated to co-load paclitaxel and indocyanine green.HD10 NPs significantly enhanced the cytotoxicity of low-dose paclitaxel because of active and mitochondrial targeting by HA and TPGS,respectively.PTT could further sensitize tumor cells toward chemotherapy by promoting apoptosis into the advanced period,highly activating caspase 3 enzyme,and significantly reducing the expression of survivin and MMP-9 proteins.Further,the anti-tumor effects of HD10 NPs delivered through different administration routes were conducted on the 4 T1 tumorbearing mice.After a single administration,HD10 NPs delivered with DMNs showed the best antitumor effect when giving chemotherapy alone.As expected,the anti-tumor effect was profoundly enhanced after combined therapy,and complete tumor ablation was achieved in the mice treated with DMNs and intra-tumor injection.Moreover,DMNs showed better safety due to moderate hyperthermia.Therefore,the DMNs along with combined chemo-photothermal therapy provide a viable treatment option for superficial tumors. | Tingting Peng Yao Huang Xiaoqian Feng Chune Zhu Shi Yin Xinyi Wang Xuequn Bai Xin Pan Chuanbin Wu | 2021 | Acta Pharmaceutica Sinica B2021，11，10： | 4 |
| 9 | Synthesis of taurine-fluorescein conjugate and evaluation of its retina-targeted efficiency in vitro显示文摘In this work, retinal penetration of fluorescein was achieved in vitro by covalent attachment of taurine to fluorescein, yielding the F-Tau conjugate. Nuclear magnetic resonance (NMR) and high resolution mass spectrometry (HRMS) were used to confirm the successful synthesis of F-Tau. The cellular uptake of F-Tau in adult retinal pigment epithelial cells (ARPE-19) and human retinal microvascular endothelial cells (hRMECs) was visualized via confocal scanning microscopy. The results indicated an improvement of solubility and a reduction of logP of F-Tau compared with fluorescein. As compared with fluorescein, F-Tau showed little toxicity, and was retained longer by cells in uptake experiments. F-Tau also displayed higher transepithelial permeabilities than fluorescein in ARPE-19 and hRMECs monolayer cells (Po0.05). These results showed that taurine may be a useful ligand for targeting small-molecule hydrophobic pharmaceuticals into the retina. | Meihong Huang Jiaqi Song Bingzheng Lu Huizhi Huang Yizhen Chen Wei Yin Wenbo Zhu Xinwen Su Chuanbin Wu Haiyan Hu | 2014 | Acta Pharmaceutica Sinica B2014，4，6： | 4 |
| 10 | Impact of particle size and pH on protein corona formation of solid lipid nanoparticles:A proof-of-concept study显示文摘When nanoparticles were introduced into the biological media,the protein corona would be formed,which endowed the nanoparticles with new bio-identities.Thus,controlling protein corona formation is critical to in vivo therapeutic effect.Controlling the particle size is the most feasible method during design,and the infuence of media pH which varies with disease condition is quite important.The impact of particle size and pH on bovine serum albumin(BSA)corona formation of solid lipid nanoparticles(SLNs)was studied here.The BSA corona formation of SLNs with increasing particle size(120-480 nm)in pH 6.0 and 7.4 was investigated.Multiple techniques were employed for visualization study,conformational structure study and mechanism study,etc.'BSA corona-caused aggregation'of SLN2-3 was revealed in pH 6.0 while the dispersed state of SLNs was maintained in pH 7.4,which signifcantly affected the secondary structure of BSA and cell uptake of SLNs.The main interaction was driven by van der Waals force plus hydrogen bonding in p H 7.4,while by electrostatic attraction in pH 6.0,and size-dependent adsorption was confrmed.This study provides a systematic insight to the understanding of protein corona formation of SLNs. | Wenhao Wang Zhengwei Huang Yanbei Li Wenhua Wang Jiayu Shi Fangqin Fu Ying Huang Xin Pan Chuanbin Wu | 2021 | Acta Pharmaceutica Sinica B2021，11，4： | 3 |
| 11 | “Pincer movement”:Reversing cisplatin resistance based on simultaneous glutathione depletion and glutathione S-transferases inhibition by redox-responsive degradable organosilica hybrid nanoparticles显示文摘The therapeutic efficacy of cisplatin has been restricted by drug resistance of cancers.Intracellular glutathione(GSH)detoxification of cisplatin under the catalysis of glutathione S-transferases(GST)plays important roles in the development of cisplatin resistance.Herein,a strategy of“pincer movement”based on simultaneous GSH depletion and GST inhibition is proposed to enhance cisplatin-based chemotherapy.Specifically,a redox-responsive nanomedicine based on disulfide-bridged degradable organosilica hybrid nanoparticles is developed and loaded with cisplatin and ethacrynic acid(EA),a GST inhibitor.Responding to high level of intracellular GSH,the hybrid nanoparticles can be gradually degraded due to the break of disulfide bonds,which further promotes drug release.Meanwhile,the disulfide-mediated GSH depletion and EA-induced GST inhibition cooperatively prevent cellular detoxification of cisplatin and reverse drug resistance.Moreover,the nanomedicine is integrated into microneedles for intralesional drug delivery against cisplatin-resistant melanoma.The in vivo results show that the nanomedicine-loaded microneedles can achieve significant GSH depletion,GST inhibition,and consequent tumor growth suppression.Overall,this research provides a promising strategy for the construction of new-type nanomedicines to overcome cisplatin resistance,which extends the biomedical application of organosilica hybrid nanomaterials and enables more efficient chemotherapy against drug-resistant cancers. | Boyi Niu Yixian Zhou Kaixin Liao Ting Wen Sixian Lao Guilan Quan Xin Pan Chuanbin Wu | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 3 |
| 12 | Solid lipid dispersion of calcitriol with enhanced dissolution and stability显示文摘Solid dispersion of calcitriol with lipophilic surfactants and triglycerides was developed by melt-mixing method to modify the release and enhance stability of the drug.The solid dispersions were characterized by differential scanning calorimetry(DSC),hot stage polarized optical microscopy(HSPM),infrared spectroscopy(FTIR)and stability studies.The solid dispersion significantly enhanced the stability of calcitriol,which could be attributed to the high antioxidant activity of the solid lipid dispersion.The rapid dissolution rate from the solid dispersion was attributed to the amorphous or solid solution state of drug with improved specific surface area and wettability than the drug crystals.Therefore,solid dispersion of calcitriol with D-a-tocopheryl polyethylene glycol 1000 succinate(TPGS)offers a good approach to modify the release and enhance stability of calcitriol.The influence of lipophilic solid dispersion on drug bioavailability needs further investigation. | Ting Yuan Lingzhen Qin Zhouhua Wang Jinyuan Nie Zhefei Guo Ge Li Chuanbin Wu | 2013 | Asian Journal of Pharmaceutical Sciences2013，8，1： | 2 |
| 13 | Self-assembly nanomicelle-microneedle patches with enhanced tumor penetration for superior chemo-photothermal therapy显示文摘Nanomedicine with high specificity has been a promising tool for cancer diagnosis and therapy.However,the successful application of nanoparticle-based superficial cancer therapy is severely hindered by restricted deep tumor tissue accumulation and penetration.Herein,a self-assembly nanomicelle dissolving microneedle(DMN)patch according to the“nano in micro”strategy was conducted to co-deliver a first-line chemotherapeutic agent paclitaxel(PTX),and a photosensitizer IR780(PTX/IR780-NMs@DMNs)for chemo-photothermal synergetic melanoma therapy.Upon direct insertion into the tumor site,DMNs created a regular and multipoint three-dimensional drug depot to maximize the tumor accumulation.Accompanied by the DMN dissolution,the composition of the needle matrixes self-assembled into nanomicelles,which could efficiently penetrate deep tumor tissue.Upon laser irradiation,the nanomicelles could not only ablate tumor cells directly by photothermal conversion but also trigger PTX release to induce tumor cell apoptosis.In vivo results showed that compared with intravenous injection,IR780 delivered by PTX/IR780-NMs@DMNs was almost completely accumulated at the tumor site.The antitumor results revealed that the PTX/IR780-NMs@DMNs could effectively eliminate tumors with an 88%curable rate without any damage to normal tissues.This work provides a versatile and generalizable framework for designing self-assembly DMN-mediated combination therapy to fight against superficial cancer. | Ying Sun Minglong Chen Dan Yang Wanbing Qin Guilan Quan Chuanbin Wu Xin Pan | 2022 | Nano Research2022，15，3： | 2 |
| 14 | Optimization of a doxycycline hydroxypropyl-β-cyclodextrin inclusion complex based on computational modeling显示文摘To prepare a stable complex of doxycycline(Doxy)and hydroxypropy-β-cyclodextrin(HP-β-CD)for ophthalmic delivery,the optimum formulation and preparation conditions were investigated using response surface methodology(RSM),artificial neural network(ANN)and support vector machine(SVM)modeling.The molar ratios of HP-β-CD/Doxy and Mg^(2+)/Doxy,inclusion time and temperature were selected as independent variables (X_(1)-X_(4)) and inclusion efficiency and stability of the Doxy-HP-β-CD complex were selected as dependent(response)variables(Y_(1) and Y_(2)).The optimal formulation predicted by genetic algorithm(GA)combined with the models was characterized by microscopy and nuclear magnetic resonance spectrometry,and the stability of Doxy in the complex was evaluated.The highest values of Y_(1) and Y_(2) were obtained using an ANN model combined with GA which predicted the values of X_(1)-X_(4) to be 4,10.8,12 h and 25℃,respectively.The modeling and optimization results indicated that a feed-forward back-propagation ANN with one hidden layer and 10 hidden units showed better fitting to both responses compared to the RSM and SVM models.GA proved to be an efficient tool in multiobjective optimization of a pharmaceutical formulation. | Zhouhua Wang Zixin He Lei Zhang Haohao Zhang Meimei Zhang Xinguo Wen Guilan Quan Xintian Huang Xin Pan Chuanbin Wu | 2013 | Acta Pharmaceutica Sinica B2013，3，2： | 2 |
| 15 | Celastrol enhances transcription factor EB (TFEB)-mediated autophagy and mitigates Tau pathology:Implications for Alzheimer's disease therapy显示文摘Alzheimer's disease(AD),characterized by the accumulation of protein aggregates including phosphorylated Tau aggregates,is the most common neurodegenerative disorder with limited therapeutic agents.Autophagy plays a critical role in the degradation of phosphorylated Tau aggregates,and transcription factor EB(TFEB)is a master regulator of autophagy and lysosomal biogenesis.Thus,small-molecule autophagy enhancers targeting TFEB hold promise for AD therapy.Here,we found that celastrol,an active ingredient isolated from the root extracts of Tripterygium wilfordii(Lei Gong Teng in Chinese)enhanced TFEB-mediated autophagy and lysosomal biogenesis in vitro and in mouse brains.Importantly,celastrol reduced phosphorylated Tau aggregates and attenuated memory dysfunction and cognitive deficits in P301S Tau and 3xTg mice,two commonly used AD animal models.Mechanistical studies suggest that TFEB-mediated autophagy-lysosomal pathway is responsible for phosphorylated Tau degradation in response to celastrol.Overall,our findings indicate that Celastrol is a novel TFEB activator that promotes the degradation of phosphorylated Tau aggregates and improves memory in AD animal models.Therefore,Celastrol shows potential as a novel agent for the treatment and/or prevention of AD and other tauopathies. | Chuanbin Yang Chengfu Su Ashok Iyaswamy Senthil Kumar Krishnamoorthi Zhou Zhu Sichang Yang Benjamin Chunkit Tong Jia Liu Sravan G.Sreenivasmurthy Xinjie Guan Yuxuan Kan Aston Jiaxi Wu Alexis Shiying Huang Jieqiong Tan Kingho Cheung Juxian Song Min Li | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 2 |
| 16 | Studies on the spray dried lactose as carrier for dry powder inhalation显示文摘The purpose of this study was to investigate the spray dried lactose as carrier for dry powder inhalation(DPI).The lactose particles were prepared by spray drying,then the particle size,shape and crystal form were characterized by laser diffraction,scanning electron microscopy(SEM),X-ray diffraction(XRD)and differential scanning calorimetry(DSC).The spray dried lactose particles were spherical and amorphous,but would transfer to crystal form when storage humidity was above 32%.Thus,the humidity of the storage environment should be controlled below 30%strictly in order to maintain the amorphous nature of spray dried lactose which is a great benefit to DPI development. | Linna Wu Xu Miao Ziyun Shan Ying Huang Lu Li Xin Pan Qinghe Yao Ge Li Chuanbin Wu | 2014 | Asian Journal of Pharmaceutical Sciences2014，9，6： | 1 |

| 18 | Virus-inspired surface-nanoengineered antimicrobial liposome:A potential system to simultaneously achieve high activity and selectivity显示文摘Enveloped viruses such as SARS-CoV-2 frequently have a highly infectious nature and are considered effective natural delivery systems exhibiting high efficiency and specificity.Since simultaneously enhancing the activity and selectivity of lipopeptides is a seemingly unsolvable problem for conventional chemistry and pharmaceutical approaches,we present a biomimetic strategy to construct lipopeptide-based mimics of viral architectures and infections to enhance their antimicrobial efficacy while avoiding side effects.Herein,a surface-nanoengineered antimicrobial liposome(SNAL)is developed with the morphological features of enveloped viruses,including a moderate size range,lipid-based membrane structure,and highly lipopeptide-enriched bilayer surface.The SNAL possesses virus-like infection to bacterial cells,which can mediate high-efficiency and high-selectivity bacteria binding,rapidly attack and invade bacteria via plasma membrane fusion pathway,and induce a local“burst”release of lipopeptide to produce irreversible damage of cell membrane.Remarkably,viral mimics are effective against multiple pathogens with low minimum inhibitory concentrations(1.6-6.3μg mL1),high bactericidal efficiency of>99%within 2 h,>10-fold enhanced selectivity over free lipopeptide,99.8%reduction in skin MRSA load after a single treatment,and negligible toxicity.This bioinspired design has significant potential to enhance the therapeutic efficacy of lipopeptides and may create new opportunities for designing next-generation antimicrobials. | Yin Shi Xiaoqian Feng Liming Lin Jing Wang Jiaying Chi Biyuan Wu Guilin Zhou Feiyuan Yu Qian Xu Daojun Liu Guilan Quan Chao Lu Xin Pan Jianfeng Cai Chuanbin Wu | 2021 | Bioactive Materials2021，6，10： | 1 |

| 20 | A real-time and modular approach for quick detection and mechanism exploration of DPIs with different carrier particle sizes显示文摘Dry powder inhalers(DPIs) had been widely used in lung diseases on account of direct pulmonary delivery, good drug stability and satisfactory patient compliance. However, an indistinct understanding of pulmonary delivery processes(PDPs) hindered the development of DPIs. Most current evaluation methods explored the PDPs with over-simplified models, leading to uncompleted investigations of the whole or partial PDPs. In the present research, an innovative modular process analysis platform(MPAP) was applied to investigate the detailed mechanisms of each PDP of DPIs with different carrier particle sizes(CPS). The MPAP was composed of a laser particle size analyzer, an inhaler device,an artificial throat and a pre-separator, to investigate the fluidization and dispersion, transportation,detachment and deposition process of DPIs. The release profiles of drug, drug aggregation and carrier were monitored in real-time. The influence of CPS on PDPs and corresponding mechanisms were explored. The powder properties of the carriers were investigated by the optical profiler and Freeman Technology four powder rheometer. The next generation impactor was employed to explore the aerosolization performance of DPIs. The novel MPAP was successfully applied in exploring the comprehensive mechanism of PDPs, which had enormous potential to be used to investigate and develop DPIs. | Yingtong Cui Ying Huang Xuejuan Zhang Xiangyun Lu Jun Xue Guanlin Wang Ping Hu Xiao Yue Ziyu Zhao Xin Pan Chuanbin Wu | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 1 |
