OBJECTIVETo evaluate the effect of early enteral nutrition(EEN) on immune response and clinical outcomes after esophageal cancer operation.

METHODSSixty patients with esophageal cancer undergoing radical operation between March 2010 and July 2011 were randomly divided into two groups using envelope method: EEN group(n=30, administration of water and enteral nutrition early after operation) and TPN group(n=30, administration of total parenteral nutrition). Two groups both received 7-day nutrition support. Immune indexes(CD3(+), CD4(+), CD8(+), CD4(+)/CD8(+)) and serum nutritional indexes(albumin, pre-albumin, transferrin) were measured before operation and 1-, 3-, and 7-day after operation. The time to first flatus, length of postoperative hospital stay, total hospitalization cost, and postoperative complication were recorded.

RESULTSAs compared to TPN group, the time to first flatus was significantly shorter in EEN group[(66.5±7.3) h vs. (75.1±6.8) h, P<0.01], as was hospital stay[(7.8±1.1) d vs. (9.3±1.3) d, P<0.01]. Total hospitalization cost[(36 210±3810) yuan vs. (39 731±4013) yuan, P<0.01] was lower in EEN group as compared to TPN group. There was no significant difference in postoperative complication rate between the two groups[13.3%(3/30) vs. 20.0%(6/30), P>0.05]. The levels of CD3(+), CD4(+), CD4(+)/CD8(+), albumin, prealbumin and transferrin were significantly higher in EEN group as compared to TPN group on postoperative day 3 and 7(all P<0.05), while CD8(+) was significantly lower in EEN group(P<0.05).

CONCLUSIONEEN can promote early recovery of gastrointestinal function, improve nutritional and immune function, and therefore lead to fast postoperative recovery in esophageal cancer patients.

Drinking culture has high significance in both China and the world, whether in the entertainment sector or in social occasions; according to the World Health Organization's 2018 Global Alcohol and Health Report, about 3 million people died from excessive drinking in 2016, accounting for 5.3% of the total global deaths that year. Oxidative stress and inflammation are the most common pathological phenomena caused by alcohol abuse (Snyder et al., 2017). Scutellarin, a kind of flavonoid, is one of the main active ingredients extracted from breviscapine. It exerts anti-inflammatory, antioxidant, and vasodilation effects, and has been used to treat cardiovascular diseases and alcoholic liver injury. Although scutellarin can effectively alleviate multi-target organ injury induced by different forms of stimulation, its protective effect on alcoholic brain injury has not been well-defined. Therefore, the present study established an acute alcohol mice brain injury model to explore the effect of scutellarin on acute alcoholic brain injury. The study was carried out based on the targets of oxidative stress and inflammation, which is of great significance for the targeted therapy of clinical alcohol diseases.

随着铜绿假单胞菌（铜绿）的耐药性逐年增强，铜绿感染已经成为公共医疗卫生的重点关注问题。线粒体自噬及其介导的线粒体功能障碍在多种细菌感染中已被报道，但线粒体功能障碍在宿主调控铜绿感染中的作用尚不明确。因此，本研究建立铜绿刺激小鼠巨噬细胞感染模型和小鼠急性铜绿感染模型，探讨铜绿是否通过诱导线粒体自噬改变线粒体功能，进而影响宿主免疫炎症反应和细胞毒性，并通过监测生存率和肺组织病理学变化进一步确定线粒体自噬在小鼠铜绿体内感染模型中的作用。结果表明，铜绿引起小鼠腹腔巨噬细胞线粒体功能障碍，并通过线粒体自噬途径清除铜绿刺激引起的活性氧（ROS）累积，从而抑制铜绿引起的促炎性细胞因子分泌并增强细胞毒性。体内实验进一步确认线粒体自噬在铜绿体内感染中的作用。

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.
