1NOMA-Based UAV-Aided Networks for Emergency Communications显示文摘High spectrum efficiency(SE)requirement and massive connections are the main challenges for the fifth generation(5G)and beyond 5G(B5G)wireless networks,especially for the case when Internet of Things(IoT)devices are located in a disaster area.Non-orthogonal multiple access(NOMA)-based unmanned aerial vehicle(UAV)-aided network is emerging as a promising technique to overcome the above challenges.In this paper,an emergency communications framework of NOMA-based UAV-aided networks is established,where the disasters scenarios can be divided into three broad categories that have named emergency areas,wide areas and dense areas.First,a UAV-enabled uplink NOMA system is established to gather information from IoT devices in emergency areas.Then,a joint UAV deployment and resource allocation scheme for a multi-UAV enabled NOMA system is developed to extend the UAV coverage for IoT devices in wide areas.Furthermore,a UAV equipped with an antenna array has been considered to provide wireless service for multiple devices that are densely distributed in disaster areas.Simulation results are provided to validate the effectiveness of the above three schemes.Finally,potential research directions and challenges are also highlighted and discussed.Wanmei Feng Jie Tang Nan Zhao Yuli Fu Xiuyin Zhang Kanapathippillai Cumanan Kai-Kit Wong 2020China Communications2020,17,11:5
2Inhaled amifostine for the prevention of radiation-induced lung injury显示文摘Objective:To alleviate radiation-induced lung injury and prevent the related pneumonitis and pulmonary fibrosis by inhaled amifostine(AMI).Methods:15 Gy 60Coγ-ray irradiation was performed on the thoracic area of rats once to establish the radiation injury model.AMI was intraperitoneally(i.p.)injected or intratracheally(i.t.)administered to the rats 30 min preirradiation.The protective effects of the two AMI administration manners were compared in the aspects of hematopoietic system,lung edema,and histopathological examination,and the mechanisms were explored.Results:Compared to i.p.AMI,i.t.AMI remarkably alleviated radiation-induced lung injury and prevented consequent pneumonitis or pulmonary fibrosis.Specifically,i.t.AMI notably protected white blood cells and platelets,reduced the lung wet/dry weight ratio,and decreased collagen volume fractions compared to the model group(P<0.05),while i.p.AMI showed no significant difference with the model group(P>0.05).The high therapeutic efficiency of i.t.AMI was related to its high antioxidation and anti-inflammation effects with downregulation of pro-inflammatory cytokines,the enhanced superoxide dismutase activity,the low levels of malondialdehyde and total proteins.Conclusion:Inhaled AMI is a promising medicine for preventing radiation-induced lung injury,including pneumonitis and pulmonary fibrosis.Ting Chen Bo Zhuang Yueqi Huang Wanmei Wang Yiguang Jin 2022Radiation Medicine and Protection2022,3,2:2

12Inhaled curcumin mesoporous polydopamine nanoparticles against radiation pneumonitis显示文摘Radiation therapy is an effective method to kill cancer cells and shrink tumors using highenergy X-ray or γ-ray. Radiation pneumonitis(RP) is one of the most serious complications of radiation therapy for thoracic cancers, commonly leading to serious respiratory distress and poor prognosis. Here,we prepared curcumin-loaded mesoporous polydopamine nanoparticles(CMPN) for prevention and treatment of RP by pulmonary delivery. Mesoporous polydopamine nanoparticles(MPDA) were successfully synthesized with an emulsion-induced interface polymerization method and curcumin was loaded in MPDA via π-π stacking and hydrogen bonding interaction. MPDA owned the uniform spherical morphology with numerous mesopores that disappeared after loading curcumin. More than 80% curcumin released from CMPN in 6 h and mesopores recovered. CMPN remarkably protected BEAS-2 B cells from γ-ray radiation injury by inhibiting apoptosis. RP rat models were established after a single dose of15 Gy^(60)Co γ-ray radiation was performed on the chest area. Effective therapy of RP was achieved by intratracheal administration of CMPN due to free radical scavenging and anti-oxidation ability, and reduced proinflammatory cytokines, high superoxide dismutase, decreased malondialdehyde, and alleviated lung tissue damages were observed. Inhaled CMPN paves a new avenue for the treatment of RP.Ting Chen Bo Zhuang Yueqi Huang Yan Liu Bochuan Yuan Wanmei Wang Tianyu Yuan Lina Du Yiguang Jin 2022Acta Pharmaceutica Sinica B2022,12,5:1

17Predatory bacterial hydrogels for topical treatment of infected wounds显示文摘Wound infection is becoming a considerable healthcare crisis due to the abuse of antibiotics and the substantial production of multidrug-resistant bacteria.Seawater immersion wounds usually become a mortal trouble because of the infection of Vibrio vulnificus.Bdellovibrio bacteriovorus,one kind of natural predatory bacteria,is recognized as a promising biological therapy against intractable bacteria.Here,we prepared a B.bacteriovorus-loaded polyvinyl alcohol/alginate hydrogel for the topical treatment of the seawater immersion wounds infected by V.vulnificus.The B.bacteriovorus-loaded hydrogel(BG)owned highly microporous structures with the mean pore size of 90μm,improving the rapid release of B.bacteriovorus from BG when contacting the aqueous surroundings.BG showed high biosafety with no L929 cell toxicity or hemolysis.More importantly,BG exhibited excellent in vitro anti-V.vulnificus effect.The highly effective infected wound treatment effect of BG was evaluated on mouse models,revealing significant reduction of local V.vulnificus,accelerated wound contraction,and alleviated inflammation.Besides the high bacterial inhibition of BG,BG remarkably reduced inflammatory response,promoted collagen deposition,neovascularization and re-epithelization,contributing to wound healing.BG is a promising topical biological formulation against infected wounds.Yan Liu Bo Zhuang Bochuan Yuan Hui Zhang Jingfei Li Wanmei Wang Ruiteng Li Lina Du Pingtian Ding Yiguang Jin 2023Acta Pharmaceutica Sinica B2023,13,1:0
18Rapid alkenylation of quinoxalin-2(1H)-ones enabled by the sequential Mannich-type reaction and solar photocatalysis显示文摘Herein,a rapid alkenylation of quinoxalin-2(1H)-ones enabled by a combination of Mannich-type reaction and solar photocatalysis is demonstrated.A wide range of functional groups are compatible,affording the corresponding products in moderate-to-good yields.Control experiments illustrate that the in situ generated^(1)O_(2)plays a central role in this reaction.This green and efficient strategy provides a practical solution for the synthesis of potentially bioactive compounds that containing a 3,4-dihydroquinoxalin-2(1H)-one structure.Lin Huang Jun Xu Lei He Chenfeng Liang Yani Ouyang Yongping Yu Wanmei Li Pengfei Zhang 2021Chinese Chemical Letters2021,32,11:0
