HAIC has demonstrated significant potential in managingadvanced HCC, particularly in regions with high prevalence rates. Despite itspromise, several challenges and areas for future research remain. Clinical studieshave substantiated the efficacy of HAIC in enhancing survival outcomes forpatients with advanced hepatic carcinoma. Notably, combination therapiesinvolving immune checkpoint inhibitors, such as lenvatinib and programmeddeath-1 inhibitors, have shown substantial improvements in median overallsurvival and progression-free survival compared to systemic chemotherapy.These combination therapies have also exhibited superior response rates anddisease control, with manageable and often less severe adverse events relative tosystemic treatments. This article is based on the review by Zhou et al and aims todiscuss the current status and future directions in the treatment of HCC, emphasizingthe role of HAIC and its integration with novel therapeutic agents.展开更多

文摘Mode-pairing quantum key distribution(MP-QKD)is an excellent scheme that can exceed the repeaterless ratetransmittance bound without complex phase locking.Nevertheless,MP-QKD usually needs to ensure that the communication distances of the two channels are equal.To address the problem,the asymmetric MP-QKD protocol is proposed.In this paper,we enhance the performance of the asymmetric MP-QKD protocol based on the advantage distillation(AD)method without modifying the quantum process.The simulation results show that the AD method can extend the communication distance by about 70 km in the case of asymmetry.And we observe that as the misalignment error increases,the AD method further increases the expandable communication distance.Our work can further enhance the robustness and promote the practical application of the asymmetric MP-QKD.
