Diffuse-type tenosynovial giant cell tumor(dTGCT) is a destructive but rare benign proliferative synovial neoplasm. Although surgery is currently the main treatment modality for dTGCT, the recurrence risk is up to 50%. Therefore, there is a great need for effective drugs against dTGCT with minor side effects. The Janus kinase(JAK)/signal transducer and activator of transcription(STAT) signaling plays a central role in rheumatoid arthritis(RA), a disease with similar characteristics as dTGCT, but its function in dTGCT remains *** fibroblast-like synoviocytes(FLS) and macrophages were isolated from 10 synovial tissue samples from dTGCT patients for the screening and validation of the five clinically approved JAK inhibitors to treat RA against dTGCT. Cell viability, cell death, inflammation and the activity of the JAK family members of cultured dTGCT FLS(both 2-D and 3-D) and macrophages were investigated for the efficacy of the JAK inhibitors. Here, we found that similar to RA, JAK/STAT signaling was markedly activated in the dTGCT synovium. Of the 5 JAK inhibitors, peficitinib was shown to have the most potency in addressing some of the pathological responses of dTGCT FLS and *** potency of peficitinib was much higher than pexidartinib, which is the only FDA-approved drug for dTGCT. Mechanistically, peficitinib inhibited tyrosine kinase 2(TYK2), a JAK family member necessary for the pathological progression of dTGCT FLS and macrophages. In summary, we not only revealed JAK/STAT(especially TYK2) signaling as the major mechanism underlying dTGCT, but also identified peficitinib as a promising drug against dTGCT.

在全面从严治党向基层延伸背景下,基层小微权力的腐败问题却屡禁不止。现阶段,农村微腐败问题主要表现为腐败主体以村两委成员为主、利益目标多重复合、涉事领域众多、贪腐金额巨大,究其原因,是由于腐败机会成本低廉、村干部“边际人”心态、农村社会资本弱化、激励保障措施缺位、组织信息沟通不畅。有鉴于此,在“五治融合”视域下,应从政治引领、自治强基、依法治国、德治教化、智治赋能等五个维度有效治理“微腐败”,营造更加风清气正的农村政治生态。

A new method was used to analyze the factors affecting the precipitation of reversed austenite during tempering. The samples were kept at various tempering temperatures for 10 min and their length changes were recorded. Then, the precipitation of reversed austenite which led to the length reduction was shown by thermal expansion curves. The results show that the effects of process parameters on the precipitation of reversed austenite can be determined more accurately by this method than by X-ray diffraction. When the quenching and tempering process is adopted, both the lower quenching temperature and higher tempering temperature can promote the precipitation of reversed austenite during tempering; and when the quenching, lamellarizing, and tempering process is used, intercritical quenching is considered beneficial to the precipitation of reversed austenite in the subsequent tempering because of Ni segregation during holding at the intercritical temperature.

视觉富文档指语义结构不仅由文本内容决定,还与排版格式和表格结构等视觉元素相关的文档。现实生活中的票据理解和证件识别等应用场景,都需要对视觉富文档进行自动化的阅读、分析和处理。这一过程即为视觉富文档理解,属于自然语言处理和计算机视觉的交叉领域。近年来,视觉富文档理解领域的预训练技术在打破下游任务的训练壁垒和提升模型表现上取得了重大的进展。然而,目前对现有的预训练模型的归纳总结和深入分析仍然有所欠缺。为此,对视觉富文档理解领域预训练技术的相关研究进行了全面总结。首先,介绍了预训练技术的数据预处理阶段,包括预训练数据集和光学字符识别引擎。然后,对预训练技术的模型预训练阶段进行了阐述,提炼出单模态表示学习、多模态特征融合和预训练任务3个关键的技术模块,并基于上述模块归纳了预训练模型之间的共性和差异。此外,简要介绍了多模态大模型在视觉富文档理解领域的应用。接着,对预训练模型在下游任务上的表现进行了对比分析。最后,探讨了预训练技术面临的挑战和未来的研究方向。
