| 1 | Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy. | Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen | 2021 | Cancer Communications2021，41，11： | 29 |
| 2 | Effect of hydrophilic silica nanoparticles on hydrate formation: Insight from the experimental study显示文摘Invasion of drilling fluid into natural gas hydrate deposits during drilling might damage the reservoir,induce hydrate dissociation and then cause wellbore instability and distortion of the data from well logging. Adding nanoparticles into drilling fluid is an effective method in reducing the invasion of drilling fluid and enhancing borehole stability. However, the addition of nanoparticles might also introduce hydrate formation risk in borehole because they can act as the 'seeds' for hydrate nucleation. This paper presents an experimental study of the effect of hydrophilic silica nanoparticle on gas hydrate formation in a dynamic methane/liquid-water system. In the experiment, the ultrapure water with and without1.0 wt%–6.0 wt% concentrations of silica nanoparticles, grain sizes of 20 and 50 nm, were pressurized by methane gas under varied conditions of temperature and pressure. The induction time, the gas consumption, and the average rate of gas consumption in the system were measured and compared to those in ultrapure water. The results show that a concentration of 4.0 wt% hydrophilic SiO_2 particles with a grain size of 50 nm has a relatively strong inhibition effect on hydrate formation when the initial experimental condition is 5.0 °C and 5.0 MPa. Compared to ultrapure water, the hydrophilic nano-SiO_2 fluid increases the induction time for hydrate formation by 194% and decreases the amount and average rate of hydrate formation by 10% and 17%, respectively. This inhibition effect may be attributed to the hydrophilicity,amount and aggregation of silica nanoparticle according to the results of water activity and zeta potential measurements. Our work also elucidates hydrophilic, instead of hydrophobic, nanoparticles can be added to the drilling fluid to maintain wellbore stability and to protect the hydrate reservoir from drilling mud damage, because they exhibit certain degree of hydrate inhibition which can reduce the risk of hydrate reformation and aggregation during gas hydrate or deep water drilling if their concentration can be controlled properly. | Ren Wang Tianle Liu Fulong Ning Wenjia Ou Ling Zhang Zhen Wang Li Peng Jiaxin Sun Zhichao Liu Tianshu Li Huicui Sun Guosheng Jiang | 2019 | Journal of Energy Chemistry2019，28，3： | 12 |
| 3 | Neural Mechanisms of Mental Fatigue Revisited: New Insights from the Brain Connectome显示文摘Maintaining sustained attention during a prolonged cognitive task often comes at a cost: high levels of mental fatigue. Heuristically, mental fatigue refers to a feeling of tiredness or exhaustion, and a disengagement from the task at hand;it manifests as impaired cognitive and behavioral performance. In order to effectively reduce the undesirable yet preventable consequences of mental fatigue in many real-world workspaces, a better understanding of the underlying neural mechanisms is needed, and continuous efforts have been devoted to this topic. In comparison with conventional univariate approaches, which are widely utilized in fatigue studies, convergent evidence has shown that multivariate functional connectivity analysis may lead to richer information about mental fatigue. In fact, mental fatigue is increasingly thought to be related to the deviated reorganization of functional connectivity among brain regions in recent studies. In addition, graph theoretical analysis has shed new light on quantitatively assessing the reorganization of the brain functional networks that are modulated by mental fatigue. This review article begins with a brief introduction to neuroimaging studies on mental fatigue and the brain connectome, followed by a thorough overview of connectome studies on mental fatigue. Although only a limited number of studies have been published thus far, it is believed that the brain connectome can be a useful approach not only for the elucidation of underlying neural mechanisms in the nascent field of neuroergonomics, but also for the automatic detection and classification of mental fatigue in order to address the prevention of fatigue-related human error in the near future. | Peng Qi Hua Ru Lingyun Gao Xiaobing Zhang Tianshu Zhou Yu Tian Nitish Thakor Anastasios Bezerianos Jinsong Li Yu Sun | 2019 | Engineering2019，5，2： | 5 |

| 7 | Flexible and flame-retarding phosphorylated MXene/polypropylene composites for efficient electromagnetic interference shielding显示文摘Flame-retardant composites with high electromagnetic interference(EMI)shielding performance are desirable for electronic device packaging.Despite great potential of MXene for high EMI,it still remains a great challenge to develop high-performance flame-retardant polymer/MXene composites with excellent EMI shielding effectiveness because of the poor oxidative stability of MXene.Herein,phosphorylated MXene/polypropylene(PP)composites are prepared by coating phosphorylated MXene on PP fabric followed by spraying polyethylenimine(PEI)and hot-pressing.The phosphorylated MXene proves to be more durable against oxidation than pure MXene due to the protection effect of polyphosphates.Upon hot-pressing,melted PP fibers are fused together at their contact points and thus as-prepared composites are bi-continuous with two interpenetrating phases.The composites show significantly improved thermal stability and flame retardancy relative to pure PP,with a low total heat release(THR)of 3.7 kJ/g and a heat release rate(HRR)of 50.0 W/g,which are reduced by 78%and 87%,respectively.In addition,the composites exhibit a high electrical conductivity of~36,700 S/m and an EMI shielding performance of~90 d B over the whole frequency range of 8–12 GHz with a thickness of~400μm.The as-developed PP/MXene composites hold great promise for reliable protection of next-generation electronic devices working in complex environments. | Tingting Tang Shanchi Wang Yue Jiang Zhiguang Xu Yu Chen Tianshu Peng Fawad Khan Jiabing Feng Pingan Song Yan Zhao | 2022 | Journal of Materials Science & Technology2022，，16： | 1 |

| 9 | Bone targeting antioxidative nano-iron oxide for treating postmenopausal osteoporosis显示文摘Osteoporosis is the most common degenerative orthopedic disease in the elderly.Recently,the therapeutic methods for osteoporosis have shifted towards the regulation of local immunity in bone tissues,which could provide a suitable environment for the positive regulation of bone metabolism,promoting osteogenic differentiation and inhibiting osteoclast differentiation.Our previous work demonstrated that iron oxide nanoparticles(IONPs)could positively regulate bone metabolism in vitro.In this study,we further demonstrated that daily administration of IONPs relieved estrogen deficiency-induced osteoporosis via scavenging reactive oxygen species in vivo.Meanwhile,IONPs promoted the osteogenic differentiation of bone marrow mesenchymal stem cells and inhibited the osteoclast differentiation of monocytes from IONPs treated mice.Besides,alendronate,a clinically used anti-osteoporosis bisphosphate,was employed to precisely deliver the IONPs to the bone tissues and played a synergically therapeutic role.Eventually,we verified the bone targeting ability,therapeutic efficiency,and biocompatibility of the novel bone target iron oxides in ovariectomy-induced osteoporotic mice.By applying BTNPs,the OVX-induced osteoporosis was significantly revised in mice models via the positive regulation of bone metabolism. | Liming Zheng Zaikai Zhuang Yixuan Li Tianshu Shi Kai Fu Wenjin Yan Lei Zhang Peng Wang Lan Li Qing Jiang | 2022 | Bioactive Materials2022，7，8： | 1 |

| 11 | Natural co-infection of fowl adenovirus type E-8b and avian hepatitis E virus in parental layer breeders in Hebei,China显示文摘Dear Editor,Fowl adenovirus(FAdV)and avian hepatitis E virus(aHEV)are the most important causative agents of hepatic injury,representing one of the greatest health concerns in layer chicken flocks(LCFs)in China and causes substantial economic losses.FAdVs are non-enveloped,double-stranded DNA viruses containing a genome of 43–45 kb in size and belong to the genus Aviadenovirus in the family of Adenoviridae(Hess,2000).Based on restriction enzyme digestion patterns and serum cross-neutralization tests,FAdV is currently clustered into five species(FAdV-A–FAdV-E)with 12 serotypes(FAdV-1 to-7,FAdV-8a,FAdV-8b,and FAdV-9 to-11).Different serotypes of FAdVs cause different clinical symptoms in poultry flocks.FAdV-1 can induce gizzard erosion in chickens,whereas inclusion body hepatitis(IBH)in chickens is often associated with FAdV-2,-8a,-8b,and-11.FAdV-4 causes hydropericardium hepatitis syndrome and IBH in chickens,and its infections have caused severe economic losses in the global poultry industry(Ye et al.,2016).Avian hepatitis E virus(aHEV)is a major causative agent of big liver and spleen disease(BLS),hepatitis splenomegaly syndrome,and hepatic rupture hemorrhage syndrome(HRHS)in chickens(Sun et al.,2019). | Lidan Hou Zengna Chi Yawen Zhang Qi Xue Tianshu Zhai Shuang Chang Jia Wang Peng Zhao | 2023 | Virologica Sinica2023，38，2： | 0 |
| 12 | Nicotine and its metabolite cotinine target MD2 and inhibit TLR4 signaling显示文摘Nicotine is the principal alkaloid of tobacco often manufactured into cigarettes and belongs to a highly addictive class of drugs.Nicotine attenuates the neuroinflammation induced by microglial activation.However,the molecular target(s)underlying anti-inflammatory action of nicotine has not been fully understood.Considering the psychoactive substances morphine,cocaine,and methamphetamine act as xenobiotic-associated molecular patterns and can be specifically sensed by the innate immune receptor Toll-like receptor 4(TLR4),here we sought to delineate whether nicotine and/or its metabolite cotinine may be recognized by the innate immune system via myeloid differentiation protein 2(MD2). | Hongyuan Li Yinghua Peng Cong Lin Xiaozheng Zhang Tianshu Zhang Yibo Wang Yuanpeng Li Siru Wu Hongshuang Wang Mark RHutchinson Linda RWatkins Xiaohui Wang | 2021 | The Innovation2021，2，2： | 0 |
