Abstract

With the continuous popularization of smart medicine, the protective effect of silibinin in the liver has attracted much attention. This study mainly explores the liver protection mechanism and absorption promotion technology of silybin based on intelligent medical analysis. Refining of silibinin: accurately weigh 1.0 g of silibinin in a three-necked flask; gradually add 50 mL of anhydrous methanol, reflux and filter the precipitated solid; and weigh it after drying. ICR male mice were taken as experimental subjects and randomly divided into groups of 10 each. The mice in the normal group and the model group were given intragastrically with 0.5% CMC-Na solution; the mice in the silibinin group were given intragastrically with SB/CMC-Na suspension; the mice in the remaining groups were given low, medium, and high-dose suspensions to their stomachs, and silibinin 23 acylate/CMC-Na suspension was administered at a dose of 10 mL/kg for 7 consecutive days. After that, the mice were fasted for 12 hours. After 6 hours of fasting (18 hours after modeling), the blood cells from their orbits were taken, placed in a 37°C water bath for 30 minutes, and centrifuged at 4000 rpm for 10 minutes, and then the serum was taken; the activity equivalent of AST and ALT in serum was measured; serum determination Medium AST and ALT vitality. The mice were killed by decapitation, fresh liver tissue was immediately collected, and part of it was frozen in liquid nitrogen for the RT-PCR test. The hepatocyte expansion and death were observed using a transmission electron microscope, and the oncosis index (OI) was calculated. Another part of the liver tissue was fixed in 4% paraformaldehyde solution, embedded in paraffin, dehydrated, and sliced at 4 m. Some sections were stained with conventional HE, and the pathological changes of liver cells were observed under light microscope; some sections were subjected to immunohistochemistry. Only one mouse died when 240 mg/kg of silibinin was given 10 minutes after the model was modeled. However, when 240 mg/kg silibinin was given to the mice 20 minutes after modeling, the mortality rate of the mice rose to 50%, and the therapeutic effect was significantly weakened. This research is helpful to advance the research of silybin in liver protection.

摘要

随着智能医学的不断普及,水飞蓟宾在肝脏中的保护作用引起了广泛关注。本研究主要基于智能医学分析,探讨水飞蓟宾的肝保护机制和吸收促进技术。水飞蓟宾的精制:准确称取 1.0g 水飞蓟宾于三颈瓶中;逐渐加入 50ml 无水甲醇,回流过滤沉淀固体;干燥后称重。ICR 雄性小鼠作为实验对象,随机分为 10 组,每组 10 只。正常组和模型组小鼠灌胃给予 0.5%CMC-Na 溶液;水飞蓟宾组小鼠灌胃给予 SB/CMC-Na 混悬液;其余各组小鼠灌胃给予低、中、高剂量混悬液,水飞蓟宾 23 乙酰基/CMC-Na 混悬液按 10ml/kg 剂量给药,连续 7 天。然后,小鼠禁食 12 小时。禁食 12 小时后(造模后 6 小时),从眼眶取血,置于 37°C 水浴中 30 分钟,4000rpm 离心 10 分钟,取血清;测定血清中 AST 和 ALT 活力的活性当量;血清测定中 AST 和 ALT 活力。小鼠断头处死,立即采集新鲜肝组织,一部分用液氮冷冻,用于 RT-PCR 试验。用透射电镜观察肝细胞扩张和死亡情况,计算细胞肿胀指数(OI)。另取部分肝组织固定于 4%多聚甲醛溶液中,包埋于石蜡中,脱水,4μm 切片。部分切片常规 HE 染色,光镜下观察肝细胞病理变化;部分切片行免疫组织化学染色。模型建立后 10 分钟给予 240mg/kg 水飞蓟宾时,只有 1 只小鼠死亡,但模型建立后 20 分钟给予 240mg/kg 水飞蓟宾时,小鼠死亡率上升至 50%,治疗效果明显减弱。本研究有助于推进水飞蓟宾在肝脏保护方面的研究。
