Ionizing radiation produces excessive reactive oxygen species （ROS） which impose detrimental effects on biological systems. Thus, it is important to explore clinically safe and efficacious radioprotection agents to scavenge ROS and reduce the risks of radiotherapy. Recently, emerging catalytic nanomaterials such as sulfide nanomaterials have shown capability of clearing ROS in vivo by unique electron transfers between atoms, but their catalytic activities are yet suboptimal. As such, there is an unmet need to improve cat- alytic properties for stronger antioxidant activities and radiation protection. Herein, we prepared ultra- small Au-MoS2 clusters （~***） and they showed enhanced catalytic properties via gold intercalation facilitating increased active sites and synergistic effects. Electrocatalysis results revealed that the catalytic activity of Au-MoS2 towards 1-1202 was superior to ultrasmall MoS2 without Au. As a result, we found that improving the electrocatalytic property of Au-MoS2 can effectively enhance corre- sponding antioxidant activities and radioprotection effects in vivo. In addition, Au-MoS2 also showed sig- nificant radioprotection in vitro and dramatically reduced the excess of radiation-induced adverse ROS. It also rescued radiation-induced DNA damages and protected the bone marrow hematopoietic system from ionizing radiation.

China's criminal norms of juvenile delinquency suffer problems such as outdated legislative models, a lack of special provisions on convictions, an extensive criminal punishment system, and an oversimplified rights recovery system. Therefore, it is necessary to find an appropriate path to improve and strengthen the protection of special, prior rights of minors, based on updating relevant concepts. From the perspective of the law of juvenile delinquency, the law of human development reflects the decisiveness of juvenile delinquency, and the law of age-crime curve showcases the stages of juvenile delinquency. In terms of the treatment of juveniles who have committed crimes, the approach to juvenile delinquency in criminal law should shift from “commutation for children at discretion” to “child-friendly” and from social defense to individual rehabilitation. Based on conceptual updating, the criminal norms for juvenile delinquency should be improved in four aspects: first, establishing special rules to broaden the path of exculpation; second, promoting the leniency of sentencing by taking into account the perpetrator factor; third, introducing special types of punishment and methods of enforcement to strengthen preventive and educational punishments; fourth, building a multilevel rights recovery system to ensure the rehabilitation and development of juvenile offenders.

In the wake of the successful conclusion of the 20thNational Congress of the Communist Party of China(CPC), we held a seminar themed on “Deeply Studying and Implementing the Spirit of the 20thCPC National Congress and Adhering to the Chinese Path of Human Rights Development”. The event happened at the right time as it took place right after the congress and was of great significance. Here, I would like to share some of my views on how to study, promote and implement the spirit of the 20thCPC National Congress in the human rights sector.
