| 1 | Chinese expert consensus on conversion therapy for hepatocellular carcinoma(2021 edition)显示文摘Recent advances in systemic and locoregional treatments for patients with unresectable or advanced hepatocellular carcinoma(HCC)have resulted in improved response rates.This has provided an opportunity for selected patients with initially unresectable HCC to achieve adequate tumor downstaging to undergo surgical resection,a‘conversion therapy’strategy.However,conversion therapy is a new approach to the treatment of HCC and its practice and treatment protocols are still being developed.Review the evidence for conversion therapy in HCC and develop consensus statements to guide clinical practice.Evidence review:Many research centers in China have accumulated significant experience implementing HCC conversion therapy.Preliminary findings and data have shown that conversion therapy represents an important strategy to maximize the survival of selected patients with intermediate stage to advanced HCC;however,there are still many urgent clinical and scientific challenges for this therapeutic strategy and its related fields.In order to summarize and learn from past experience and review current challenges,the Chinese Expert Consensus on Conversion Therapy for Hepatocellular Carcinoma(2021 Edition)was developed based on a review of preliminary experience and clinical data from Chinese and non-Chinese studies in this field and combined with recommendations for clinical practice.Sixteen consensus statements on the implementation of conversion therapy for HCC were developed.The statements generated in this review are based on a review of clinical evidence and real clinical experience and will help guide future progress in conversion therapy for patients with HCC. | Hui-Chuan Sun Jian Zhou Zheng Wang Xiufeng Liu Qing Xie Weidong Jia Ming Zhao Xinyu Bi Gong Li Xueli Bai Yuan Ji Li Xu Xiao-Dong Zhu Dousheng Bai Yajin Chen Yongjun Chen Chaoliu Dai Rongping Guo Wenzhi Guo Chunyi Hao Tao Huang Zhiyong Huang Deyu Li Gang Li Tao Li Xiangcheng Li Guangming Li Xiao Liang Jingfeng Liu Fubao Liu Shichun Lu Zheng Lu Weifu Lv Yilei Mao Guoliang Shao Yinghong Shi Tianqiang Song Guang Tan Yunqiang Tang Kaishan Tao Chidan Wan Guangyi Wang Lu Wang Shunxiang Wang Tianfu Wen Baocai Xing Bangde Xiang Sheng Yan Dinghua Yang Guowen Yin Tao Yin Zhenyu Yin Zhengping Yu Bixiang Zhang Jialin Zhang Shuijun Zhang Ti Zhang Yamin Zhang Yubao Zhang Aibin Zhang Haitao Zhao Ledu Zhou Wu Zhang Zhenyu Zhu Shukui Qin Feng Shen Xiujun Cai Gaojun Teng Jianqiang Cai Minshan Chen Qiang Li Lianxin Liu Weilin Wang Tingbo Liang Jiahong Dong Xiaoping Chen Xuehao Wang Shusen Zheng Jia Fan 无 | 2022 | Hepatobiliary Surgery and Nutrition2022，11，2： | 4 |
| 2 | Proper animal experimental designs for preclinical research of biomaterials for intervertebral disc regeneration显示文摘Low back pain is a vital musculoskeletal disease that impairs life quality,leads to disability and imposes heavy economic burden on the society,while it is greatly attributed to intervertebral disc degeneration(IDD).However,the existing treatments,such as medicines,chiropractic adjustments and surgery,cannot achieve ideal disc regeneration.Therefore,advanced bioactive therapies are implemented,including stem cells delivery,bioreagents administration,and implantation of biomaterials etc.Among these researches,few reported unsatisfying regenerative outcomes.However,these advanced therapies have barely achieved successful clinical translation.The main reason for the inconsistency between satisfying preclinical results and poor clinical translation may largely rely on the animal models that cannot actually simulate the human disc degeneration.The inappropriate animal model also leads to difficulties in comparing the efficacies among biomaterials in different reaches.Therefore,animal models that better simulate the clinical charateristics of human IDD should be acknowledged.In addition,in vivo regenerative outcomes should be carefully evaluated to obtain robust results.Nevertheless,many researches neglect certain critical characteristics,such as adhesive properties for biomaterials blocking annulus fibrosus defects and hyperalgesia that is closely related to the clinical manifestations,e.g,low back pain.Herein,in this review,we summarized the animal models established for IDD,and highlighted the proper models and parameters that may result in acknowledged IDD models.Then,we discussed the existing biomaterials for disc regeneration and the characteristics that should be considered for regenerating different parts of discs.Finally,well-established assays and parameters for in vivo disc regeneration are explored. | Yizhong Peng Xiangcheng Qing Hongyang Shu Shuo Tian Wenbo Yang Songfeng Chen Hui Lin Xiao Lv Lei Zhao Xi Chen Feifei Pu Donghua Huang Xu Cao Zengwu Shao | 2021 | Biomaterials Translational2021，2，2： | 2 |
| 3 | Decellularized Disc Hydrogels for hBMSCs tissue-specific differentiation and tissue regeneration显示文摘Tissue specificity,a key factor in the decellularized tissue matrix(DTM),has shown bioactive functionalities in tuning cell fate-e.g.,the differentiation of mesenchymal stem cells.Notably,cell fate is also determined by the living microenvironment,including material composition and spatial characteristics.Herein,two neighboring tissues within intervertebral discs,the nucleus pulposus(NP)and annulus fibrosus(AF),were carefully processed into DTM hydrogels(abbreviated DNP-G and DAF-G,respectively)to determine the tissue-specific effects on stem cell fate,such as specific components and different culturing methods,as well as in vivo regeneration.Distinct differences in their protein compositions were identified by proteomic analysis.Interestingly,the fate of human bone marrow mesenchymal stem cells(hBMSCs)also responds to both culturing methods and composition.Generally,hBMSCs cultured with DNP-G(3D)differentiated into NP-like cells,while hBMSCs cultured with DAF-G(2D)underwent AF-like differentiation,indicating a close correlation with the native microenvironments of NP and AF cells,respectively.Furthermore,we found that the integrin-mediated RhoA/LATS/YAP1 signaling pathway was activated in DAF-G(2D)-induced AF-specific differentiation.Additionally,the activation of YAP1 determined the tendency of NP-or AF-specific differentiation and played opposite regulatory effects.Finally,DNP-G and DAF-G specifically promoted tissue regeneration in NP degeneration and AF defect rat models,respectively.In conclusion,DNP-G and DAF-G can specifically determine the fate of stem cells through the integrin-mediated RhoA/LATS/YAP1 signaling pathway,and this tissue specificity is both compositional and spatial,supporting the utilization of tissue-specific DTM in advanced treatments of intervertebral disc degeneration. | Yizhong Peng Xiangcheng Qing Hui Lin Donghua Huang Jinye Li Shuo Tian Sheng Liu Xiao Lv Kaige Ma Rui Li Zilong Rao Ying Bai Songfeng Chen Ming Lei Daping Quan Zengwu Shao | 2021 | Bioactive Materials2021，6，10： | 1 |
| 4 | Endogenous repair theory enriches construction strategies for orthopaedic biomaterials:a narrative review显示文摘The development of tissue engineering has led to new strategies for mitigating clinical problems;however,the design of the tissue engineering materials remains a challenge.The limited sources and inadequate function,potential risk of microbial or pathogen contamination,and high cost of cell expansion impair the efficacy and limit the application of exogenous cells in tissue engineering.However,endogenous cells in native tissues have been reported to be capable of spontaneous repair of the damaged tissue.These cells exhibit remarkable plasticity,and thus can differentiate or be reprogrammed to alter their phenotype and function after stimulation.After a comprehensive review,we found that the plasticity of these cells plays a major role in establishing the cell source in the mechanism involved in tissue regeneration.Tissue engineering materials that focus on assisting and promoting the natural self-repair function of endogenous cells may break through the limitations of exogenous seed cells and further expand the applications of tissue engineering materials in tissue repair.This review discusses the effects of endogenous cells,especially stem cells,on injured tissue repairing,and highlights the potential utilisation of endogenous repair in orthopaedic biomaterial constructions for bone,cartilage,and intervertebral disc regeneration. | Yizhong Peng Jinye Li Hui Lin Shuo Tian Sheng Liu Feifei Pu Lei Zhao Kaige Ma Xiangcheng Qing Zengwu Shao | 2021 | Biomaterials Translational2021，2，4： | 1 |
