Hepatocellular carcinoma （HCC） is a highly aggressive liver malignancy and the main form of liver cancer. Early diagnosis and treatment of HCC can effectively reduce mortality. Carboxylesterase （CE）-specific detection and imaging can be used for early diagnosis and image-guided surgical of HCC. However, traditional optical probes suffer from poor selectivity and low imaging signal-to-noise ratio. Here, we have constructed a series of chemiluminescent probes for carboxylesterase detection based on the strategy of enzymatic pocket-oriented steric tailoring techniques. The probes with different unique and excellent properties have been obtained through the structure-based steric hindrance adjustment on the recognition site. Here, CE-2 has been successfully used for high-throughput screening of rapid carboxylesterase inhibitors due to its extremely low detection limit (2.5×10-4U mL-1) and fast recognition ability. CE-3 has been successfully used for image-guided surgery of orthotopic hepatocellular carcinoma due to its ultra-long chemiluminescence imaging （over 12 h） of hepatocellular carcinoma. This study may promote advances in the rapid detection and screening of inhibitory drugs for CE and the field of surgical navigation in HCC.

本研究通过3个实验探索了初中生认知控制对替代性攻击行为的影响以及认知控制影响替代性攻击行为的激惹和触发情境边界条件。实验1考察了一般性认知控制对替代性攻击行为的影响,结果发现一般性认知控制不能有效降低替代性攻击行为的攻击比例。实验2探讨了特异性认知控制对替代性攻击行为的有效抑制作用,结果发现无论在高激惹情境还是低激惹情境,主动控制和反应性控制启动条件下的替代性攻击行为均显著低于基线水平。实验3则探究了特异性认知控制抑制替代性攻击行为的激惹和触发情境边界条件,结果发现特异性认知控制、激惹情境、触发情境三者的交互作用显著,激惹和触发情境能够有效调节特异性认知控制对替代性攻击行为的影响。而且,在高激惹高触发和高激惹低触发情境下,主动性控制减基线的攻击比例显著高于反应性控制减基线,但在低激惹高触发和低激惹低触发情境下主动性控制减基线的攻击比例与反应性控制减基线不存在显著差异。此外,高激惹高触发情境下主动性控制减基线的攻击比例是所有条件下最高的。以上结果说明,特异性认知控制能够有效抑制初中生的替代性攻击行为,其中主动性控制的情境边界出现在高激惹高触发情境。
