Biochar as an emerging carbonaceous material has exhibited a great potential in environ-mental application for its perfect adsorption ability.However,there are abundant persistent free radicals(PFRs)in biochar,so the direct and indirect PFRs-mediated removal of organic and inorganic contaminants by biochar was widely reported.In order to comprehend deeply the formation of PFRs in biochar and their interactions with contaminants,this paper re-views the formation mechanisms of PFRs in biochar and the PFRs-mediated environmental applications of biochar in recent years.Finally,future challenges in this field are also pro-posed.This review provides a more comprehensive understanding on the emerging appli-cations of biochar from the viewpoint of the catalytic role of PFRs.

目的 探讨胫骨高位截骨结合膝关节镜下微骨折术治疗膝内侧骨关节炎的早期疗效.方法 2018年8月至2020年8月,采用胫骨高位截骨术及关节镜下微骨折术治疗膝内侧间室骨关节炎共12例,男5例,女7例,年龄49～66岁,平均(53.0±0.8)岁.术前行膝关节磁共振均提示内侧胫骨平台软骨面损伤.先采用关节镜下清理+微骨折术,再行胫骨高位截骨术(均为单侧手术).所有患者均随访半年以上,进行美国特种外科医院(hospital for special surgery,HSS)膝关节评分,测量术前、术后胫股角(femo
胫骨高位截骨(high tibial osteotomy,HTO)是治疗膝内侧骨关节炎的一种有效“保膝”方法,通过转移不良下肢力线(hip-knee-ankle angle,HKA),改善内侧间室软骨磨损情况,延缓膝骨关节炎(knee osteoarthritis,KOA)进展[1],包括内侧开放楔形截骨术和外侧闭合楔形截骨术.传统手术方式往往借助术者手术经验、C臂机下反复透视确定理想截骨方案,容易造成截骨量过多,手术时间、术中出血量增加,术后胫骨平台骨折、后倾角改变、矫正过度或矫正不足等并发症的发生,影
