Skin is one of the most vulnerable tissues,but there is a lack of injectable bioactive hydrogel dressings,which possess high strength,antiswelling capacity,and wet tissue adhesiveness,but also a rapid gelling process to enable rapid hemostasis,sutureless wound closure,and scarless healing of infected skin wounds[1e5].A new injectable,antibacterial,and multifunctional hydrogel dressings based on poly(citric acid-co-polyethylene glycol)-g-dopamine(PCPD)and amino-terminated Pluronic F127(APF)mi-celles loaded with astragaloside IV(AS)was developed for this pur-pose,as shown in Fig.1A[6].

本试验以脂多糖(LPS)诱导的小鼠巨噬细胞RAW264.7为试验材料,研究水蔓菁总黄酮的体外抗炎活性及其机制。采用MTT法检测水蔓菁总黄酮的细胞毒性,中性红试验测定细胞吞噬能力,Griess法检测一氧化氮(NO)的生成量,酶联免疫吸附测定(ELISA)法检测白细胞介素-1β(IL-1β)、白细胞介素-6(IL-6)、肿瘤坏死因子-α(TNF-α)、前列腺素E2(PGE2)、诱导型一氧化氮合酶(iNOS)和环氧合酶-2(COX-2)的生成量,Western blot法检测核因子-κB(NF-κB)信号通路相关蛋白表达量。结果显示:质量浓度为200μg/mL的水蔓菁总黄酮对小鼠巨噬细胞RAW264.7无显著毒性(P>0.05)。不同质量浓度(25、50、100、200、300、400μg/mL)的水蔓菁总黄酮均能显著或极显著增强LPS诱导的小鼠巨噬细胞RAW264.7的吞噬能力(P<0.05或P<0.01),显著或极显著抑制NO、IL-1、IL-6、TNF-α、PGE2、iNOS和COX-2的生成量及磷酸化核因子-κB p65 (p-NF-κB p65)和磷酸化核因子-κB抑制蛋白α(p-IκBα)的蛋白表达量(P<0.05或P<0.01),并能显著或极显著增强核因子-κB抑制蛋白α(IκBα)的蛋白表达量(P<0.05或P<0.01)。综上可知,水蔓菁总黄酮能增强小鼠巨噬细胞的吞噬能力,并能够通过抑制细胞内iNOS、COX-2、NO和炎症因子的生成和调控NF-κB信号通路相关蛋白表达来发挥体外抗炎活性。

Weight gain after 35 years of age is associated with increased breast cancer risk: findings from a large prospective cohort study

Cancer Biology & Medicine 2024年第8期21卷 651-655页

Adiposity affects lifetime estrogen exposure, which is a key factor in breast carcinogenesis. However, adiposity effects,often assessed as the body mass index （BMI）, on pre-and post-menopausal breast cancer risk are paradoxical. Body weight gain may reflect body fat mass accumulation during adulthood better than the BMI, potentially representing age-related metabolic changes1.
