褐藻胶对肝豆状核变性小鼠肝脏的保护作用机制研究

[摘要] 目的：研究褐藻胶对肝豆状核变性（HLD）小鼠肝脏的保护作用机制。方法：健康雄性昆明小鼠，应用铜负荷饮食法建立HLD模型。治疗组每天给予褐藻胶灌胃，对照组动物同步给予等体积的生理盐水灌胃，每日1次，连续4周。电感耦合等离子体质谱法检测尿铜含量；生化法检测血清丙氨酸氨基转移酶（ALT）和门冬氨酸氨基转移酶（AST）活性、血清总蛋白和白蛋白含量；HE染色观察肝细胞病理变化；Masson染色观察肝纤维化程度；TUNEL检测肝细胞凋亡；免疫组化检测肝细胞铜蓝蛋白（CER）表达水平。结果：经褐藻胶治疗后，高剂量组小鼠的尿铜含量较模型组显著降低（P<0.05），血清ALT、AST活性较模型组显著降低（P<0.05）。肝细胞变性指数、肝纤维化程度和凋亡细胞指数较模型组均显著减少（P<0.05），肝细胞CER表达水平较模型组显著升高（P<0.05）。结论：褐藻胶可能通过增强肝细胞CER的表达和促进Cu2+的排泄，减轻肝细胞变性凋亡和肝纤维化损害，改善HLD小鼠的肝功能。

Effect of iron deficiency without anaemia on days alive and out of hospital in patients undergoing valvular heart surgery

Comprehensive evidence regarding the treatment of non-anaemic iron deficiency in patients undergoing valvular heart surgery is lacking. This study aimed to investigate the association between non-anaemic iron deficiency and postoperative outcomes in these patients. We retrospectively analysed 321 patients of which 180 (56%) had iron deficiency (defined as serum ferritin < 100 ng.ml^-1 or < 300 ng.ml^-1 with transferrin saturation < 20%). While the iron-deficient group had lower pre-operative haemoglobin levels than the non-iron deficient group (median (IQR [range]) 134 (127–141 [120–172]) g.l^-1, 143 (133–150 [120–179]) g.l^-1, p = 0.001), there was no between-group difference in allogeneic red blood cell transfusion. Median (IQR [range]) days alive and out of hospital at postoperative day 90 was 1 day shorter in the iron-deficient group (80 (77–82 [9–85]) days vs. 81 (79–83 [0–85]) days, p = 0.026). In multivariable analysis, only cardiopulmonary bypass duration (p = 0.032) and intra-operative allogeneic red blood cell transfusion (p = 0.011) were significantly associated with reduced days alive and out of hospital at postoperative day 90. Iron deficiency did not exert any adverse influence on secondary outcomes except length of hospital stay. Our findings indicate that non-anaemic iron deficiency alone is not associated with adverse effects in patients undergoing valvular heart surgery when it does not translate into an increased risk of allogeneic transfusion.
