In Section 2.2. 'Animal Experiments' of their article, the authors noted that: "All the animal studies were conducted in accordance with protocols approved by the Animal Ethics Committee of China Japan Friendship Hospital" (Zhang et al., 2018). Following concerns raised to the journal by a reader regarding the study's ethical approval process, the authors would like to inform readers that, due to a translation error and a misunderstanding of the process, prospective ethical approval for this study was mistakenly not sought. However, the protocols followed for this study in relation to the care and use of animals were undertaken in accordance with the animal care and use policies of the Animal Ethical and Welfare Committee (AEWC) of the Clinical Institute of China Japan Friendship Hospital.

The authors apologise for this error.

在第 2.2 节中。作者在文章的“动物实验”中指出：“所有动物研究均按照中日友好医院动物伦理委员会批准的方案进行”（Zhang et al.,  2018）。在读者就该研究的伦理批准程序向该杂志提出担忧之后，作者想通知读者，由于翻译错误和对该程序的误解，错误地没有寻求对本研究的预期伦理批准。然而，本研究遵循的有关动物护理和使用的协议是根据中日友好医院临床研究所动物伦理和福利委员会 (AEWC) 的动物护理和使用政策进行的。

作者为这个错误道歉。
