Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APC^min/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.

Objective To compare the dosimetric characteristics of thyroid between intensity-modulated radiotherapy (IMRT) and volumetric modulated arc therapy (VMAT) in patients with left-sided breast cancer after modified radical mastectomy. Methods Thirty patients with left-sided breast cancer who underwent adjuvant radiotherapy after modified radical mastectomy at the Huangpu Branch of the Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine, from December 2021 to May 2023, were selected as the study subjects, and IMRT and VMAT were used with a target prescription dose of 50 Gy/25 times. The target dose parameters of the two plans, including the mean dose (D_mean) and the dose-volume limit for organs at risk (V_x, x represents dose), were compared. Results The conformity index of VMAT was higher than that of IMRT (P＜0.001). Compared with VMAT, IMRT plan significantly reduced the V₅、V₁₀、D_mean of heart, the V₅ of right lung and the D_mean of right breast, while it significantly increased the V₂₀ of left lung (P＜0.001). There was no statistically significant difference in V₅ and V₁₀ of the left thyroid between IMRT and VMAT. However, the V₂₀, V₃₀, V₄₀, and D_mean of left and whole thyroid, and the V₁₀ and D_mean of right thyroid were significantly lower in IMRT than those in VMAT (P＜0.001). Conclusions Both IMRT and VMAT plans can meet the clinical dosimetric requirements, among which IMRT has lower thyroid exposure dose and is more suitable for patients with high cardiac requirements.

Osteoporosis is an emerging threat characterized by systemic damage to bone mass and microarchitecture leading to fragility fractures.Exosomes are nanosized vesicular particles secreted by cells into the extracellular compartment with biological activities similar to those of their cell of origin and play an important role in intercellular communication processes.Exosomes from multiple cell sources are involved in the regulation of bone-related cell proliferation and differentiation during bone metabolism,and have the advantages of high stability,non-immunogenicity and strong targeting ability,which make up for the shortcomings of traditional drug and stem cell therapies.Exosomes secreted from bone marrow mesenchymal stem cells(MSCs)can promote bone regeneration and improve morphology,biomechanics and histological damage,and exosomes derived from bone marrow mesenchymal stem cells(BMSCs)in the mechanical microenvironment are more effective in inducing osteogenesis,significantly enhancing the osteogenic effect of BMSCs and promoting bone regeneration.Therefore,this article provides a review on the mechano-sensitivity of MSCs,mechanical responsive functionalized exosomes of MSCs,and explores their potential role in the treatment of osteoporosis.

OBJECTIVE: To review the research progress of design of bone scaffolds with different single cell structures. METHODS: The related literature on the study of bone scaffolds with different single cell structures at home and abroad in recent years was extensively reviewed, and the research progress was summarized. RESULTS: The single cell structure of bone scaffold can be divided into regular cell structure, irregular cell structure, cell structure designed based on topology optimization theory, and cell structure designed based on triply periodic minimal surface. Different single cell structures have different structural morphology and geometric characteristics, and the selection of single cell structure directly determines the mechanical properties and biological properties of bone scaffold. It is very important to choose a reasonable cell structure for bone scaffold to replace the original bone tissue. CONCLUSION Bone scaffolds have been widely studied, but there are many kinds of bone scaffolds at present, and the optimization of single cell structure should be considered comprehensively, which is helpful to develop bone scaffolds with excellent performance and provide effective support for bone tissue.

OBJECTIVE: To summarize the influence of microstructure on performance of triply-periodic minimal surface (TPMS) bone scaffolds. METHODS: The relevant literature on the microstructure of TPMS bone scaffolds both domestically and internationally in recent years was widely reviewed, and the research progress in the imfluence of microstructure on the performance of bone scaffolds was summarized. RESULTS: The microstructure characteristics of TPMS bone scaffolds, such as pore shape, porosity, pore size, curvature, specific surface area, and tortuosity, exert a profound influence on bone scaffold performance. By finely adjusting the above parameters, it becomes feasible to substantially optimize the structural mechanical characteristics of the scaffold, thereby effectively preempting the occurrence of stress shielding phenomena. Concurrently, the manipulation of these parameters can also optimize the scaffold's biological performance, facilitating cell adhesion, proliferation, and growth, while facilitating the ingrowth and permeation of bone tissue. Ultimately, the ideal bone fusion results will obtain. CONCLUSION The microstructure significantly and substantially influences the performance of TPMS bone scaffolds. By deeply exploring the characteristics of these microstructure effects on the performance of bone scaffolds, the design of bone scaffolds can be further optimized to better match specific implantation regions.

Femoral fracture is a common type of fracture in clinical practice, and poor fracture reduction may lead to malunion and dysfunction. At present, traditional reduction with manipulation and intramedullary nailing are the mainstream treatments, but there exist problems such as X-ray exposure or poor reduction. Fracture reduction robots are of positive significance in improving the safety of surgical treatment of femur fracture, avoiding repetitive operations and poor alignment, and shortening the patients′ postoperative recovery time. Navigation algorithm is the key to achieve the function of femoral repositioning. Understanding the advantages and disadvantages that various types of navigation algorithms demonstrated in femoral reduction applications is important for giving full play to the value of fracture reduction robots in femoral reduction. Therefore, the authors reviewed the research progress in existing robot navigation algorithms applied in femoral fracture repositioning from the following four aspects, including image alignment algorithm, algorithm for establishing the target pose of femoral repositioning, algorithm for compensating the mechanical error, and algorithm for path planning, hoping to provide a reference for the application and research of navigation algorithms of fracture reduction robots.

Bone defects, often accompanied by osteomyelitis, soft tissue contusions, etc, are facing lengthy treatment process and slow healing, seriously jeopardizing the structural integrity of the human bone tissue. Currently, the main treatment for bone defects involves autologous or allogeneic bone transplant. However, autologous bone transplant poses problems, including long surgical duration, increased pain and complications such as infections. Additionally, immune rejection reactions also limit the effectiveness of allogeneic bone transplant of the same species. Bone scaffolds have become a potential alternative for bone transplant, but problems such as sharp edges of the scaffolds and poor compatibility with human tissues exist. Triply periodic minimal surface (TPMS), with an average curvature of zero has lower levels of stress concentration and the ability to be precisely expressed with mathematical formulas, compared with other structures. Its application in bone scaffolds attracts much attention, but there is currently a lack of comprehensive understanding of the impacts of different types of TPMS on the performance of bone scaffolds. With this purpose, the authors reviewed the research progress in the impacts of different types of TPMS on the performance of bone scaffolds, providing a reference for the construction of bone scaffolds.
