Zhongguo shiyan zhenduanxue, 2007 目的研究氧化应激反应对染氟成骨细胞增殖活性的作用。方法取昆明小鼠乳鼠颅骨进行成骨细胞培养,应用生化方法检测细胞内蛋白和丙二醛（MDA）含量及超氧化物歧化酶（SOD）、谷胱甘肽过氧化物酶（GPX）活性。结果暴露于低水平氟（0.5-1mgF-/L）的成骨细胞脂质过氧化物MDA水平明显较低,但在2 mgF-/L组MDA水平明显提高;长时间（≥72 h）暴露于高水平氟的成骨细胞MDA含量显著增多。染氟24-72 h的成骨细胞GPX活性在低氟（0.5-2.0 mgF-/L）组明显升高 ...

Rare Metals, Volume 45, Issue 1, January 2026.ABSTRACT Nanozymes have attracted considerable attention in cancer therapy due to their adjustable enzyme activity and high catalytic efficiency. However, they still face a major challenge from tumor metastasis. In this work, endogenous/exogenous dual‐responsive bimetallic hollow PdRu (termed HPdRu) nanozymes were prepared.

萝卜硫素激活Nrf2通路抑制内质网应激改善博来霉素诱导的肺纤维化
Zhongguo shiyan zhenduanxue, 2023 肺纤维化是一种常见的间质性肺疾病，临床症状表现为干咳和呼吸困难，伴有限制性通气功能异常和弥散功能降低，其发病率逐年上升，且预后不佳。其病理早期表现为肺泡细胞损伤和凋亡，最终出现细胞外成纤维细胞增殖及胶原沉积。研究表明，失控的氧化应激、氧化/抗氧化平衡失调是诱导肺纤维化发生的分子学基础[1];内质网应激(ERS)通过促进肺泡上皮细胞凋亡、改变上皮细胞表型、促进成纤维细胞分化等方式也参与纤维化的发生及发展[2]。

Zhongguo shiyan zhenduanxue, 2016 一些致瘤因子可诱导细胞发生氧化应激,氧化应激是细胞内外产生活性氧（ROS）并诱导细胞毒作用的过程。生理状态下,细胞通过抗氧化系统维持ROS平衡;氧化应激时,ROS破坏生物大分子造成细胞损伤,进而产生致癌作用,并作为第二信使参与调控凋亡信号。高浓度ROS则对肿瘤产生细胞毒作用并抑制增殖。120ROS20ROS是细胞代谢过程中产生的一系列含氧物质,包括超氧阴离子（O-2）、羟自由基（OH·）和过氧化氢（H2O2）。

Biotechnology and Applied Biochemistry, Volume 72, Issue 5, Page 1385-1394, October 2025.ABSTRACT Senkyunolide I (Sen I) has a protective effect on the blood–brain barrier (BBB) in rats with sepsis‐associated encephalopathy (SAE). This study investigated whether Sen I regulates Nrf2 to ameliorate sepsis‐induced brain dysfunction (SIBD). Sixty rats were randomly assigned into Sham group, SAE group (Model group), SAE + Sen I group (72 mg/kg,
