背景:跟腱断裂术后的再生与重塑是临床治疗的难点,组织工程水凝胶材料为促进跟腱修复提供了可能。目的:探究单宁酸改性互穿网络水凝胶对大鼠断裂跟腱组织再生与重塑的作用。方法:①通过蓝光照射及CaSO4溶液浸泡交联制备单宁酸改性互穿网络水凝胶,表征水凝胶的微观形貌、力学性能、黏附性能、体外释药性能与生物相容性。②取30只SD大鼠,采用随机数字表法分为假手术组、手术组与水凝胶组,每组10只,后2组建立右后肢跟腱断裂模型,手术组采用改良Kessler法将断裂跟腱重新缝合,水凝胶组采用相同术式缝合断裂跟腱后将单宁酸改性互穿网络水凝胶贴片完全缠绕包裹于断端接合处。术后4周,对断裂跟腱进行影像学检查、组织学评价、生物力学测试及炎症因子水平检测。结果与结论:①扫描电镜下可见单宁酸改性互穿网络水凝胶呈多孔微观结构,孔径为3-10μm,并且水凝胶具备良好的体外释药性能、黏附强度与拉伸强度;CCK-8检测与活/死染色显示,该水凝胶对大鼠骨髓间充质干细胞增殖活性无明显影响,具备良好的生物相容性。②MRI成像显示,与手术组比较,水凝胶组大鼠跟腱呈均一低信号,跟腱前后径厚度减小,与周围组织分界更为明确,表现更接近假手术组。苏木精-伊红与Masson染色显示,手术组大鼠跟腱纤维排列松散混乱,细胞密度增加且排布杂乱,伴有明显炎性细胞浸润,部分区域出现腱内骨化;水凝胶组大鼠跟腱纤维排列有序,细胞密度降低且排布规整,炎性细胞浸润明显减少。手术组大鼠跟腱的拉伸强度低于假手术组(P<0.05),水凝胶组大鼠跟腱的拉伸强度高于手术组(P<0.05)。与假手术组比较,手术组大鼠跟腱中白细胞介素1β、白细胞介素6及肿瘤坏死因子α质量浓度及mRNA表达升高(P<0.05);与手术组比较,水凝胶组3种炎症因子水平及mRNA表达降低。③结果表明,单宁酸改性互穿网络水凝胶可显著抑制局部炎症反应、促进断裂跟腱组织重塑。

This review highlights the gradient variations in the structural composition of musculoskeletal tissues and comprehensively examines recent progress in the fabrication and application of biomimetic gradient scaffolds for musculoskeletal *** challenges and prospects of gradient scaffolds for clinical application are discussed. The intricate hierarchical structure of musculoskeletal tissues, including bone and interface tissues, necessitates the use of complex scaffold designs and material structures to serve as tissue-engineered substitutes. This has led to growing interest in the development of gradient bone scaffolds with hierarchical structures mimicking the extracellular matrix of native tissues to achieve improved therapeutic outcomes. Building on the anatomical characteristics of bone and interfacial tissues, this review provides a summary of current strategies used to design and fabricate biomimetic gradient scaffolds for repairing musculoskeletal tissues, specifically focusing on methods used to construct compositional and structural gradients within the scaffolds. The latest applications of gradient scaffolds for the regeneration of bone, osteochondral, and tendon-to-bone interfaces are presented. Furthermore, the current progress of testing gradient scaffolds in physiologically relevant animal models of skeletal repair is discussed, as well as the challenges and prospects of moving these scaffolds into clinical application for treating musculoskeletal injuries.

Surveillance recommendations for gastric cancer（GC） in current guidelines focused on advanced precancerous lesions and were based on precise diagnosis of severity/extent of baseline lesions. We aimed to develop a less endoscopy-related equipment-dependent risk-stratification tool, and assessed whether mild-precursor-lesion patients can be safely exempt from surveillance. In the multicenter communitybased cohort, 75,051 participants receiving baseline endoscopy were enrolled during 2015–2017 and followed-up until 2021. Cumulative incidence rates（CIRs） of GC for precancerous-conditions were calculated by Kaplan-Meier method and compared by Log-rank tests. Mixedeffects Cox regression models were used to detect potential factors for progression towards GC. A risk score was calculated as counts of selected factors. An independent cohort, including 26,586 participants was used for external validation. During a median follow-up of 6.25 years, CIRs of GC were 0.302%, 0.436%, and 4.756% for normal group, non-neoplastic（atrophic gastritis/intestinal metaplasia） and neoplastic lesions（low-grade/high-grade dysplasia）, respectively(Ptrend<0.001). Four predictors, including male, ≥60 years, smoking, and limited vegetable consumption, were selected for risk-stratification. High-risk patients（≥3 risk factors） with non-neoplastic lesions showed higher GC risks（adjusted HR=7.73, 95%CI: 4.29–13.92）, and their four-year CIR reached the one-year CIR of neoplastic lesions. Further categorizing non-neoplastic lesions by histological grade, both patients with moderate-to-severe lesions（aHR=3.07, 95%CI: 1.67–5.64） and high-risk patients with mild lesions（aHR=7.29, 95%CI: 3.58–14.86） showed higher risks. Consistent trends were observed in validation cohort. High-risk mild-precursor-lesion patients should receive surveillance within 3–5 years after baseline screening. Our study provides evidence on supplementing current guideline recommendations.

Broadband and perfect terahertz absorber based on multilayer metamaterial with cross-ring patterned structures

引用

Optoelectronics Letters 2025年第1期21卷 1-6页

作者： WEN Jin LIU Zhanzhi WU Zhengwei PAN Yu zhang Ying School of Science Xi'an Shiyou University Shaanxi Key Laboratory of Measurement and Control Technology for Oil and Gas Wells

Broadband and perfect terahertz absorber based on multilayer metamaterial using cross-ring patterned structures is proposed and investigated. The structure of the absorber is double absorption layers consisting of a chromium cross ring and eight isosceles right triangles. The unique structure of the double absorbing layers excites the electric dipole multimode resonance, giving rise to high absorption performance. Meanwhile, the influence of construal parameters on absorber behavior is also discussed. The numerical results show that the absorption achieves over 90% ranging from 2.45 THz to 6.25 THz and 99% absorption in the range of 3.7—5.3 THz. The realization of broadband and perfect absorber is described using the impedance matching principle. It is obviously found that the absorber is insensitive to the high angle of incidence for both transverse electric(TE) and transverse magnetic(TM) polarizations. Compared with the former reports, this absorber has remarkable improved absorption efficiency and smaller period. The terahertz absorber may be found applications in the fields of energy capture and thermal detection.
