In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in *** this study,a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy(SERS).The Fe3O4@Au@Ag nanoparticles(NPs)deposited graphene oxide(GO)nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid(4-MPBA)to form SERS probes(GO-Fe3O4@Au@Ag-MPBA).Furthermore,doxorubicin(DOX)is attached to SERS probes through a pH-responsive linker boronic ester(GO-Fe3O4@Au@Ag-MPBA-DOX),accompanying the 4-MPBA signal change in *** the entry into tumor,the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS ***,the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS ***,the strong T2 magnetic resonance(MR)signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy(PTT).Altogether,this GO-Fe3O4@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting,pH-sensitive drug release,SERS-traceable detection and MR imaging,endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.

The private set intersection(PSI) protocol allows two parties holding a set of integers to compute the intersection of their sets without revealing any additional information to each other. The unbalanced PSI schemes consider a specific setting where a client holds a small set of the size n and a server holds a much larger set of the size m(n ■ m). The communication overhead of state-of-the-art balanced PSI schemes is O(m + n) and the unbalanced PSI schemes are O(nlogm). In this paper, we propose a novel secure unbalanced PSI protocol based on a hash proof system. The communication complexity of our protocol grows only linearly with the size of the small set. In other words, our protocol achieves communication overhead of O(n). We test the performance on a personal computer(PC) machine with a local area network(LAN)setting for the network. The experimental results demonstrate that the client only takes 2.01 s of online computation, 4.27 MB of round trip communication to intersect 1600 pieces of 32-bit integers with 220pieces of 32-bit integers with the security parameter λ = 512. Our protocol is efficient and can be applied to resource-constrained devices, such as cell phones.

针对支承门式墩施工支架的既有线桥梁可靠性分析研究相对不足的问题,研究结合实际工程实例,建立了一种针对门式墩施工对上跨既有线桥梁进行可靠性分析的计算方法。该方法首先计算初步设计的施工支架对既有桥梁的作用力;然后对既有桥梁进行实体建模分析,主梁采用八节点六面体线性减缩积分单元(C3D8R),预应力筋采用两节点线性三维桁架单元(T3D2),并将预应力钢筋以嵌入(Embed)方式置于混凝土模型内部,网格尺寸设定为1 cm,严格依照图纸进行精细装配;此外,通过模拟降温过程以施加预应力筋的预应力;然后对混凝土的强度、变形以及开裂情况进行可靠性分析。基于分析结果对初步设计的支架结构提供了针对性的改进建议。实际工程应用显示:采用这种方法进行计算,能够切实保证门式墩施工过程的安全性,同时确保既有桥梁在施工阶段的可靠性。
