方法
2
通过丙戊酸钠构建孤独症谱系障碍仔鼠模型,并分为孤独症模型组、红景天苷组、红景天苷+激活剂组,每组12只;另取12只健康仔鼠为对照组。通过开放场地测试、三腔社交测试、高架十字迷宫测试和新型物体识别测试对仔鼠进行行为障碍评估。HE染色检测仔鼠海马体变化;ELISA检测仔鼠血清中炎症因子白细胞介素(IL)-10、肿瘤坏死因子-α(TNF-α)、IL-6水平;Western blot检测海马体中HMGB1和RAGE蛋白表达水平。

Objective
2
To explore the effects of salidroside on neuroinflammation and behavioral disorders in rat pups with autism spectrum disorder by regulating the high-mobility group box 1 (HMGB1)/receptor for advanced glycation end-products (RAGE) pathway.
Methods
2
Rat pups with autism spectrum disorder models were established by sodium valproate, and the rat pups were divided into the autism model group, the salidroside group, and the salidroside+activator group, with 12 pups in each group. An additional 12 healthy rat pups were taken as the control group. Open field testing, three-chamber social preference test, elevated plus maze testing, and novel object recognition testing were used to assess behavioral disorders of rat pups. HE staining was performed to detect the histological changes in rat pups hippocampal tissue. ELISA was performed to detect the serum levels of inflammatory factors, including interleukin(IL)-10, tumor necrosis factor-alpha (TNF-α), and IL-6 in rat pups. In addition, Western blot was performed to detect the HMGB1 and RAGE protein expression levels in hippocampal tissue.
Results
2
Compared with the control group, the autism model group showed reduced central area dwell time (
P
<
0.05), decreased social ability index (SI), social preference index (SPI), anxiety index (AI), discrimination index, and IL-10 level (
P
<
0.05),increased IL-6 and TNF-α levels,as well as HMGB1 and RAGE protein expression levels(
P
<
0.05),loose arrangement and necrosis of neurons. Compared with the autism model group, the salidroside group showed increased central area dwell time (
P
<
0.05), increased SI, SPI, AI, discrimination index, and IL-10 level (
P
<
0.05), and decreased IL-6 and TNF-α levels, as well as HMGB1 and RAGE protein expression levels (
P
<
0.05), attenuated neuronal atrophy. Compared with the salidroside group, the salidroside+activator group showed reduced central area dwell time (
P
<
0.05), decreased SI, SPI, AI, discrimination index, and IL-10 levels (
P
<
0.05), and increased IL-6 and TNF-α levels, as well as HMGB1 and RAGE protein expression levels (
P
<
0.05), aggravated neuronal necrosis.
Conclusion
2
Salidroside alleviates neuroinflammation and behavioral disorders in rat pups with autism spectrum disorder by inhibiting the HMGB1/RAGE pathway.
