First-line chemoimmunotherapy(with or without bevacizumab)has improved outcomes in advanced non-small cell lung cancer(NSCLC).Here,this open-label,multi-cohort phase II study(NCT05329025)was done to investigate the safety and efficacy of QL1706(a single bifunctional MabPair product against PD-1 and CTLA-4)and chemotherapy with or without bevacizumab in this population.Patients were enrolled into five different cohorts based on genotype(cohorts 1-4,epidermal growth factor receptor[EGFR]wild-type;cohort 5,EGFR-mutant and progressed on EGFR-tyrosine kinase inhibitors[TKIs]).Between June 11,2021 and December 29,2021,91 patients were enrolled.Most frequent treatment-related adverse events(TRAEs)included decreased appetite(60[65.9%]),anemia(60[65.9%]),infusion-related reactions(48[52.7%]),and pruritus(44[48.4%]).Grade≥3 TRAEs occurred in 30(33.0%)patients.Twenty-seven(45%)patients with wild-type EGFR achieved partial response(PR)(objective response rate[ORR]=45%)and had a median progression-free survival(mPFS)of 6.8 months(95%CI:5.2-9.7).For 31 patients harboring mutated EGFR,17(54.8%)achieved PR(ORR=54.8%),with an mPFS of 8.5 months(95%CI:5.72-not evaluable).Overall,QL1706 plus chemotherapy,regardless of having bevacizumab,was generally tolerable and had promising antitumor activity for EGFR wild-type advanced NSCLC in first-line setting.Moreover,QL1706 plus chemotherapy and bevacizumab showed favorable antitumor activity for patients who had EGFR mutated NSCLC but failed in TKI therapy,demonstrating a potential for treating this population.

Accurate simulation of the evolution of freak waves by the wave phase focusing method requires accurate linear and nonlinear properties,especially in deep-water conditions.In this paper,we analyze the ability to simulate deep-water focused waves of a two-layer Boussinesq-type(BT)model,which has been shown to have excellent linear and nonlinear performance.To further improve the numerical accuracy and stability,the internal wavegenerated method is introduced into the two-layer Boussinesq-type model.Firstly,the sensitivity of the numerical results to the grid resolution is analyzed to verify the convergence of the model;secondly,the focused wave propagating in two opposite directions is simulated to prove the symmetry of the numerical results and the feasibility of the internal wave-generated method;thirdly,the limiting focused wave condition is simulated to compare and analyze the wave surface and the horizontal velocity of the profile at the focusing position,which is in good agreement with the measured values.Meanwhile the simulation of focused waves in very deep waters agrees well with the measured values,which further demonstrates the capability of the two-layer BT model in simulating focused waves in deep waters.

Hepatotoxicity is a common side effect for patients treated with gefitinib,but the related pathogenesis is unclear and lacks effective predictor and management strategies.A multi-omics approach integrating pharmacometabolomics,pharmacokinetics and pharmacogenomics was employed in non-small cell lung cancer patients to identify the effective predictor for gefitinib-induced hepatotoxicity and explore optional therapy substitution.Here,we found that patients with rs4946935 AA,located in Forkhead Box O3(FOXO3)which is a well-known autophagic regulator,had a higher risk of hepatotoxicity than those with the GA or GG variant(OR=18.020,95%CI=2.473 to 459.1784,P=0.018)in a gefitinib-concentration dependent pattern.Furthermore,functional experiments identified that rs4946935_A impaired the expression of FOXO3 by inhibiting the promotor activity,increasing the threshold of autophagy initiation and inhibiting the autophagic activity which contributed to gefitinib-induced liver injury.In contrast,erlotinib-induced liver injury was independent on the variant and expression levels of FOXO3.This study reveals that FOXO3 mutation,leading to autophagic imbalance,plays important role in gefitinib-induced hepatotoxicity,especially for patients with high concentration of gefitinib.In conclusion,FOXO3 mutation is an effective predictor and erlotinib might be an appropriately and well-tolerated treatment option for patients carrying rs4946935 AA.

Anaplastic lymphoma kinase(ALK)rearrangements are present in about 5–6%of non-small cell lung cancer(NSCLC)cases and associated with increased risks of central nervous system(CNS)involvement.Envonalkib,a novel ALK inhibitor,demonstrated promising anti-tumor activity and safety in advanced ALK-positive NSCLC in the first-in-human phase I study.This phase III trial(ClinicalTrials.gov NCT04009317)investigated the efficacy and safety of first-line envonalkib in advanced ALK-positive NSCLC cases.Totally 264 participants were randomized 1:1 to receive envonalkib(n=131)or crizotinib(n=133).Median independent review committee(IRC)-assessed progression-free survival(PFS)times were 24.87(95%confidence interval[CI]:15.64–30.36)and 11.60(95%CI:8.28–13.73)months in the envonalkib and crizotinib groups,respectively(hazard ratio[HR]=0.47,95%CI:0.34–0.64,p<0.0001).IRC-assessed confirmed objective response rate(ORR)was higher(81.68%vs.70.68%,p=0.056)and duration of response was longer(median,25.79[95%CI,16.53–29.47]vs.11.14[95%CI,9.23–16.59]months,p=0.0003)in the envonalkib group compared with the crizotinib group.In participants with baseline brain target lesions,IRC-assessed CNS-ORR was improved with envonalkib compared with crizotinib(78.95%vs.23.81%).Overall survival(OS)data were immature,and median OS was not reached in either group(HR=0.84,95%CI:0.48–1.47,p=0.5741).The 12-month OS rates were 90.6%(95%CI,84.0%–94.5%)and 89.4%(95%CI,82.8%–93.6%)in the envonalkib and crizotinib groups,respectively.Grade≥3 treatment-related adverse events were observed in 55.73%and 42.86%of participants in the envonalkib and crizotinib groups,respectively.Envonalkib significantly improved PFS and delayed brain metastasis progression in advanced ALK-positive NSCLC.

Background:Bone metastases are common in patients with advanced cancer.Bisphosphonates(BPs) could prevent or delay the development of skeleton-related events(SREs).The present study aimed to identify the clinical features of and treatment strategies for Chinese patients with bone metastases.Methods:Consecutive cancer patients who had bone metastases and received BP treatment were enrolled.A questionnaire was developed to collect the patients' clinical data,as well as information on the diagnosis and management of bone metastases.Physicians' awareness of the guidelines and knowledge of the application of BP were also assessed.Results:A total of 3223 patients with lung cancer(36.5%),breast cancer(30.9%),prostate cancer(8.5%),and gastrointestinal cancer(5.7%) were included in this study.The sites of bone metastases were the thoracic spine(56.0%),lumbar spine(47.1%),ribs(32.6%),and pelvis(23.2%).The SRE frequency was the highest in patients with multiple myeloma(36.6%),followed by those with lung cancer(25.9%),breast cancer(20.2%),prostate cancer(18.2%),and gastrointestinal cancer(17.3%).Irradiation to the bone was the most frequent SRE(58%in lung cancer patients,45%in breast cancer patients,and 48%in prostate cancer patients).Our survey also showed that 45.5%of patients received BP within 3 months after their diagnosis of bone metastases,whereas the remaining 54.5%of patients did not receive BP treatment until at least 3 months after their diagnosis of bone metastases.The SRE frequency in the former group was significantly lower than that in the latter group(4.0%vs.42.3%,P < 0.05).In patients with more than 6 months of continuous BP treatment,the mean time to the first SRE was significantly longer than that in patients with less than 6 months of continuous BP treatment(7.2 vs.3.4 months,P < 0.05).In addition,12.2%of the physicians were not aware of the efficacy of BP in preventing and delaying SRE.Only half(52.3%) of the physicians agreed that the BP treatment should persist for at least 6 months unless it was intol

光催化分解水制氢,作为一种绿色、安全、高效且低成本的制氢技术,因其清洁性和巨大的发展潜力而受到广泛关注.尽管光催化分解水制氢在理论上具有显著优势,但在实际应用中仍面临捕光效率低、电荷分离难、表面反应速率慢以及光腐蚀等挑战.为解决上述问题并突破效率瓶颈,研究者们积极探索新的方法,如构建异质结、调控微观结构、引入助催化剂、掺杂和诱导缺陷等,以期提高光催化剂的性能.其中,光催化剂掺杂改性是研究热点之一.通过对光催化剂进行掺杂改性,可以有效调节其能带结构、光吸收性能以及电荷传输性能,进而提升光催化分解水制氢的效率.因此,对光催化剂掺杂在光催化分解水制氢中的作用机制和研究进展进行系统地梳理和总结,有助于深化对该领域的理解,具有重要意义.本文系统地介绍了近年来本课题组利用掺杂改性光催化剂提升光解水制氢性能的研究成果.首先,总结了光催化剂掺杂的合成方法和表征手段,并详细介绍了用于分析掺杂离子在催化剂中的分布及价态的原位表征方法.其次,以铋基复合氧化物为例,介绍了通过固溶法将稀土元素掺杂到铋基复合氧化物中,实现可见光下完全分解水,并探讨了掺杂对光催化剂能带结构的影响及作用机制.进一步,阐述了掺杂后铋基复合氧化物微观结构的变化,特别是暴露面、表面特性和缺陷态等对光生载流子分离与迁移的影响,归纳了掺杂诱导的结构变化与光催化分解水制氢性能之间的构效关系.此外,介绍了一种新颖的多局域梯度掺杂方法:利用离子扩散使预先储存掺杂离子的“纳米胶囊”持续、非均匀地释放入半导体材料中,诱导导带位置连续弯曲,从而在导带势能面内构建出多局域的势阱,从而延长了光生电子空穴对的寿命,为光生载流子提供了更多迁移至表面的通道,明显提高了光解水效率.最后,展望了光催化剂掺杂技术未来的研究方向:(1)通过对光催化分解水制氢中的析氢和析氧助催化剂进行掺杂改性,提高表面催化反应速率;(2)发展纳米催化剂上的非对称掺杂技术,在纳米颗粒内的特定区域或表面掺杂的精确调控,以提高光催化分解水制氢性能;(3)随着机器学习的进步,AI模型可以用于预测和优化掺杂条件,从而大幅减少实验量.综上,本文总结了掺杂在光催化分解水制氢研究中的研究进展,希望能为探索开发可见光光催化水分解的新型材料和提高能量转换效率提供参考和借鉴.

Background:Gefitinib,as the first epidermal growth factor receptor tyrosine kinase inhibitors(EGFR-TKI)approved for the treatment of advanced non-small cell lung cancer(NSCLC),has been proved to significantly improve the progression-free survival(PFS)in the first-line setting but suffers from resistance 7-10 months after treatment initia-tion.Apatinib(YN968D1),a potent vascular endothelial growth factor receptor(VEGFR)2-TKI,specifically binds to VEGFR2 and leads to anti-angiogenetic and anti-neoplastic effect.Concurrent inhibition of VEGFR and EGFR path-ways represents a rational approach to improve treatment responses and delay the onset of treatment resistance in EGFR-mutant NSCLC.This ACTIVE study aims to assess the combination of apatinib and gefitinib as a new treatment approach for EGFR-mutant NSCLC as a first-line setting.Methods:This multicenter,randomized,double-blind,placebo-controlled phase III study(NCT02824458)has been designed to assess the efficacy and safety of apatinib or placebo combined with gefitinib as a first-line treatment for patients with EGFR-mutant advanced NSCLC.A total of 310 patients with EGFR-mutation(19del or 21L858R),pathological stage IIIB to IV non-squamous NSCLC were to be enrolled.The primary endpoint is investigator assessment of PFS,and the secondary endpoints include independent radiological central(IRC)-confirmed PFS,overall survival(OS),objective response rate(ORR),disease control rate(DCR),time to progressive disease(TTPD),duration of response(DoR),quality of life(QoL)and safety.The patients are randomized in a 1:1 ratio to receive gefitinib(250 mg,p.o.q.d.)plus apatinib(500 mg,p.o.q.d.)or gefitinib plus placebo,given until disease progression or intolerable adverse events.Exploratory biomarker analysis will be performed.This study is being conducted across China and comprises of 30 participating centers.Enrollment commenced in August 2017 and finished in December 2018,most of the patients are in the follow-up period.Anticipated outcomes and significance:The present stud

Catalytic degradation of benzene over non-thermal plasma coupled Co-Ni binary metal oxide nanosheet catalysts

Journal of Environmental Sciences 2023年第10期132卷 1-11页

Non-thermal plasma(NTP)has been demonstrated as one of the promising technologies that can degrade volatile organic compounds(VOCs)under ambient condition.However,one of the key challenges of VOCs degradation in NTP is its relatively low mineralization rate,which needs to be addressed by introducing catalysts.Therefore,the design and optimization of catalysts have become the focus of NTP coupling catalysis research.In thiswork,a series of two-dimensional nanosheet Co-Ni metal oxides were synthesized by microwave method and investigated for the catalytic oxidation of benzene in an NTP-catalysis coupling system.Among them,Co_(2)Ni_(1)O_(x)achieves 60%carbon dioxide(CO_(2))selectivity(SCO_(2))when the benzene removal efficiency(REbenzene)reaches more than 99%,which is a significant enhancement compared with the CO_(2)selectivity obtained without any catalysts(38%)under the same input power.More intriguingly,this SCO_(2)is also significantly higher than that of single metal oxides,NiO or Co_(3)O_(4),which is only around 40%.Such improved performance of this binary metal oxide catalyst is uniquely attributed to the synergistic effects of Co and Ni in Co_(2)Ni_(1)O_(x)catalyst.The introduction of Co_(2)Ni_(1)O_(x)was found to promote the generation of acrolein significantly,one of the key intermediates found in NTP alone system reported previously,suggest the benzene ring open reaction is promoted.Compared with monometallic oxides NiO and Co_(3)O_(4),Co_(2)Ni_(1)O_(x)also shows higher active oxygen proportion,better oxygenmobility,and stronger low-temperature redox capability.The above factors result in the improved catalytic performance of Co_(2)Ni_(1)O_(x)in the NTP coupling removal of benzene.
