Lead halide perovskite quantum dots（LHP QDs） have been revealed to possess great potential in photocatalytic applications including CO2reduction, which however suffer from poor stability. Herein, a high crystalline hydrazine-linked three-dimensional（3D） covalent organic framework, USTB-17, was fabricated from the reaction between 12-connected building block and 4-connected 3,5,7-tetrakis（4-aldophenyl）-adamantane. Post-modification with Ni2+affords the metallic framework USTB-17（Ni）followed by sequential deposition of the CH3NH2PbI3（MAPbI3） perovskite QDs into its pores, generating the USTB-17（Ni）@MAPbI3composite. Powder X-ray diffraction analysis together with theoretical simulations and transmission electron microscopy discloses the crystalline nature of USTB-17, USTB-17（Ni）, and USTB-17（Ni）@MAPbI3with an unprecedented noninterpenetrated hpt topology. The close contact of QDs inside the COF pores with the Ni catalytic site locating at the pore surface of COF allows a rapid transfer of the photogenerated electrons in QDs to the Ni catalytic sites, enhancing the photocatalytic activity for CO2reduction. This endows USTB-17（Ni）@MAPbI3with efficient photocatalysis performance for photocatalytic CO2reduction with CO generation rate of 365 μmol g-1h-1and CO selectivity up to 96% under visible-light irradiation, 7 times higher than that of USTB-17（Ni）. After four cycles of reactions, the photocatalytic CO generation rate remains almost unchanged, demonstrating its excellent cycle stability.

目的探讨莫沙比利联合舒肝解郁胶囊治疗功能性消化不良临床疗效。方法运用随机数字表法将2007年9月～2011年9月在某院消化内科住院治疗的84例功能性消化不良患者分为对照组和莫沙比利联合舒肝解郁胶囊组,对照组患者仅使用莫沙比利进行治疗,而莫沙比利联合舒肝解郁胶囊组则在上述治疗的基础上加用舒肝解郁胶囊进行治疗,4周后对所有患者临床疗效进行比较。结果经过为期4周的治疗,莫沙比利联合舒肝解郁胶囊组患者总有效率(88.10%)明显高于对照组总有效率(69.05%)(χ2=4.525,P﹤0.05);而在治疗结束后6个月对所有患者进行随访,莫沙比利联合舒肝解郁胶囊组患者复发率(7.14%)明显低于对照组患者(28.57%)(χ2=6.574,P﹤0.05),2组患者不良反应均很轻,2组患者血常规、尿常规、肝肾功能及心电图检查均未见明显变化。结论莫沙比利联合舒肝解郁胶囊组患者临床疗效优于单用莫沙比利患者,具有复发率低、不良反应小等优点,是临床治疗功能性消化不良的一种安全有效的治疗方法,值得在临床推广。

With the development of quantum computing technology, quantum public-key cryptography is gradually becoming an alternative to the existing classical public-key cryptography. This paper designs a quantum trapdoor one-way function via EPR pairs and quantum measurements. Based on this, a new quantum public-key cryptosystem is presented, which offers forward security,and can resist the chosen-plaintext attack and chosen-ciphertext attack. Compared with the existing quantum public-key cryptos,eavesdropping can be automatically detected in this new quantum public-key cryptosystem under a necessary condition, which is also detailed in the paper.
