Liensinine attenuates inflammation and oxidative stress in spleen tissue in an LPS-induced mouse sepsis model / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Sepsis is a complex syndrome caused by multiple pathogens and involves multiple organ failure, particularly spleen dysfunction. In 2017, the worldwide incidence was 48.9 million sepsis cases and 11 million sepsis-related deaths were reported (Rudd et al., 2020). Inflammation, oxidative stress, and apoptosis are the most common pathologies seen in sepsis. Liensinine (LIE) is a bisbenzylisoquinoline-type alkaloid extracted from the seed embryo of Nelumbo nucifera. Lotus seed hearts have high content of LIE which mainly has antihypertensive and antiarrhythmic pharmacological effects. It can exert anti-carcinogenic activity by regulating cell, inflammation, and apoptosis signaling pathways (Manogaran et al., 2019). However, its protective effect from sepsis-induced spleen damage is unknown. In this research, we established a mouse sepsis model induced by lipopolysaccharide (LPS) and investigated the protective effects of LIE on sepsis spleen injury in terms of inflammatory response, oxidative stress, and apoptosis.

Expression and function of microRNA-218 in hepatocellular carcinoma / 国际检验医学杂志

Objective To study the expression level and function of micro RNA (microRNA)-218 in hepatocellular carcinoma (HCC) .Methods 46 cases of HCC surgery in the hepatobiliary surgery department of this hospital were selected and divided into the transfection group and nontransfection group .The expression ,proliferation and apoptosis of microRNA-218 and the expression level of B cell specific Maloney leukemia virus insertion site 1(Bmi-1) and cycling-dependented kinase 6(CDK6) in HepG2 cells were compared between the two groups .Results The expression level of microRNA-218 in HCC tissue was significantly lower than that in paracancerous tissues (P＜0 .05);the microRNA218 expression level was closely correlated with the clinicopathological characteristics such as tumor size and TNM stage(P＜0 .05);the HepG2 cell proliferation rates at 24 ,48 ,72 h after transfection in the transfection group were significantly lower than those in the nontransfection group(P＜0 .05);the HepG2 cell apoptosis rate in the transfection group was significantly higher than that in the nontransfection group(P＜0 .05);the Bim-1 and CDK6 expression levels after HepG2 cell transfection in the transfection group were significantly lower than those in nontransfection group(P＜0 .05) . Conclusion microRNA-218 can suppress the proliferation of HCC cells and promotes HCC cells apoptosis by down-regulating the Bim-1 and CDK6 expression level in potential targets .
