Objective To compare the clinical value of leukocyte-poor platelet rich plasma（LP-PRP）and leukocyte-rich platelet rich plasma（LR-PRP）combined with extracorporeal shock wave therapy（ESWT）in the treatment of chronic non -insertional Achilles tendinopathy（NIAT）．Methods Eighty patients with chronic NIAT admitted to Ganzhou People's Hospital from December 2021 to December 2023 were randomly divided into two groups using a random number table method：a control group and an observation group,with 40 patients in each group．The observation group received LP-PRP combined with ESWT treatment,while the control group received LR-PRP combined with ESWT treatment．The pain level（Visual Analog Scale[VAS]score）,degree of Achilles tendon lesion（Victorian Institute of Sports Assessment-Achilles tendinopathy questionnaire[VISA-A]）,and Achilles tendon function（Arner Lindholm Achilles tendon function score）between the two groups were compared before treatment,one month after the first treatment,and three months after treatment,as well as the incidence of complications between the two groups．Results The VAS scores of both groups decreased and the VISA-A scores increased one and three months after treatment．The VAS score of the observation group（1.05±0.31）was lower than that of the control group（1.82±0.45）three months after treatment,while the VISA-A score of the observation group（83.35±5.58）was higher than that of the control group（76.28±5.35）（interaction between group and time point F=338.478,106.663,both P<0.05）．After three months of treatment,the Achilles tendon function of the observation group（24 cases of excellent,13 cases of good,and three cases of poor）was better than that of the control group（14 cases of excellent,16 cases of good,and 10 cases of poor）,and the difference was statistically significant（Z=2.529,P=0.012）．There was no statistically significant difference in VAS score,VISA-A score,and Achilles tendon function between the two groups one month after treatment（all P>0.05）．Conclusions Compared with LR-PRP,LP-PRP combined with ESWT was more beneficial in reducing the degree of Achilles tendon pain and lesions in patients with chronic NIAT,and improving Achilles tendon function．

目的 探讨谷氨酸对HT22细胞线粒体自噬和细胞凋亡的影响,并评估虾青素预处理的保护作用及其分子机制。方法 用谷氨酸及虾青素处理HT22细胞,通过蛋白印迹及聚合酶联反应等评估其对线粒体自噬的影响。结果 谷氨酸处理显著抑制线粒体初级自噬（PINK1、Parkin、pULK1^ser555和LC3Ⅱ）和次级自噬（LAMP1和Rab7）,上调cleaved Caspase-3的表达（P<0.05）。虾青素预处理减少细胞凋亡,恢复了线粒体自噬,PINK1、Parkin、pULK1^ser555和LC3Ⅱ的表达水平上升（分别为2.3倍、2.6倍、83.3%及81.1%）（P<0.05）,该作用被自噬抑制剂BafA1阻断。此外,谷氨酸抑制Nrf2核内转移和NLRX1表达,而预处理显著促进Nrf2的核内转移并上调NLRX1,分别上调25.8%、33.2%。生物信息学分析显示NLRX1启动子区域含有3个Nrf2结合位点,提示Nrf2通过调控NLRX1转录活性发挥作用。结论 文章首次揭示虾青素通过Nrf2/NLRX1通路激活线粒体自噬,展现神经保护作用。

Objective To explore the effects of glutamate on mitophagy and apoptosis in HT22 cells and evaluate the protective effects and molecular mechanisms of astaxanthin pretreatment．Methods HT22 cells were treated with glutamate and astaxanthin．The effects on mitophagy were assessed using Western Blot and PCR．Results Glutamate treatment significantly inhibited primary mitophagy（PINK1,Parkin,pULK1^ser555 and LC3II）and secondary mitophagy（LAMP1 and Rab7）while upregulating cleaved Caspase-3 expression．Astaxanthin pretreatment notably reduced apoptosis and restored mitophagy,the expression levels of PINK1,Parkin,pULK1^Ser555 and LC3II were significantly upregulated（by 2.3-fold,2.6-fold,83.3% and 81.1% respectively,P<0.05）,but this effect was blocked by the autophagy inhibitor BafA1．Additionally,glutamate suppressed Nrf2 nuclear translocation and NLRX1 expression,whereas astaxanthin promoted Nrf2 nuclear translocation and increased NLRX1 expression by 25.8% and 33.2%,respectively．Bioinformatics analysis revealed three Nrf2 binding sites in the NLRX1 promoter region,suggesting that Nrf2 may regulate NLRX1 transcriptional activity．Conclusions The study demonstrates that astaxanthin exhibited potential neuroprotective effect by activating mitophagy through the Nrf2/NLRX1 pathway．
