## TL;DR

This study shows that Lulongzaisheng decoction, a traditional Chinese medicine, helps treat aplastic anemia in mice by reducing iron death and improving bone marrow function.

## Contribution

The study identifies the Jak2/Stat3/Acsl4 signaling pathway as a novel target for Lulongzaisheng decoction in treating aplastic anemia.

## Key findings

- Lulongzaisheng reduced bone marrow fat and improved hematopoiesis in AA mice.
- The decoction lowered lipid ROS and 4-HNE levels, indicating reduced iron death.
- It inhibited the Jak2/Stat3 pathway and reduced Acsl4 expression in AA mice.

## Abstract

探讨鹿龙再生汤对再生障碍性贫血（AA）模型小鼠铁死亡的影响及其对AA的潜在作用机制。

以近交系雌性BALB/c小鼠作为对照（对照组），应用IFN-γ腹腔注射联合白消安灌胃的方法建立AA小鼠模型组，并使用鹿龙再生汤对AA组连续灌胃10 d治疗，评估其对Jak2/Stat3/Acsl4信号通路的影响。胸骨组织病理学观察各组小鼠骨髓损伤程度；流式细胞术检测骨髓细胞中脂质活性氧（ROS）的产生；免疫组织化学染色观察胸骨中4-HNE的表达；Western blot法分析Jak2、p-Jak2、Stat3、p-Stat3及Acsl4的蛋白表达水平；ELISA法检测外周血IL-6水平。

与对照组相比，AA组小鼠骨髓腔内造血组织减少，脂肪化明显；AA+鹿龙再生汤组小鼠骨髓脂肪化减少。对照组、AA组、AA+鹿龙再生汤组骨髓细胞脂质ROS比例分别为（47.01±3.07）％、（53.81±1.99）％、（49.50±3.98）％（P<0.05），AA+鹿龙再生汤组的脂质ROS累积量较AA组略低。对照组、AA组、AA+鹿龙再生汤组骨髓腔内4-HNE的表达面积分别为（6.34±1.07）％、（35.26±3.68）％、（16.97±1.30）％（P<0.05），与AA组相比，AA+鹿龙再生汤组在骨髓4-HNE累积上显著减少。与对照组相比，AA组脾脏中铁死亡相关蛋白Acsl4表达升高，p-Stat3、p-Jak2表达上调；AA+鹿龙再生汤组Acsl4表达下调，p-Stat3、p-Jak2表达被抑制（P<0.05）。对照组、AA组、AA+鹿龙再生汤组外周血血浆IL-6的表达量分别为（65.60±6.01）、（166.50±3.32）、（119.37±4.29）pg/ml（P<0.05），AA+鹿龙再生汤组较AA组IL-6水平明显降低。

鹿龙再生汤通过调控铁死亡相关的基因Jak2/Stat3/Acsl4途径对AA模型小鼠具有显著的治疗效果。作用机制涉及抑制Jak2/Stat3信号通路以及调控Acsl4的表达，从而改善AA模型小鼠的造血功能。
