Methods A total of 120 patients with NSCLC from June 2021 to June 2023 were selected and divided into observation group and control group evenly according to the method of drawing lots,control group was treated with chemotherapy,the observation group was treated with immunotherapy combined with chemotherapy,and the clinical efficacy and adverse drug reactions were compared between the two groups．Before and after treatment,immune function（CD3⁺,CD4⁺,CD8⁺）,carbohydrate antigen 199（CA199）,carbohydrate antigen 125（CA125）,serum carcinoembryonic antigen（CEA）levels and health status questionnaire（QOL-RRB- scores）were measured．Results The total effective rate in the observation group was significantly higher than that in the control group（68.33%>41.67%,P<0.05）．After treatment,the ratios of CD3⁺ and CD4⁺ in the observation group were significantly higher than those before treatment and control group after treatment,and the ratio of CD8⁺ was significantly lower than that before and after treatment in the control group（P<0.05）．After treatment,the serum levels of CA199,CA125 and CEA in the observation group were lower than those before and after treatment in the control group（P<0.05）．The incidence of adverse drug reactions was 16.67% in the observation group and 36.67% in the control group,which was significantly lower in the observation group than in the control group（P<0.05）．After treatment,the QOL scores in the observation group were significantly higher than those in the control group and before treatment（P<0.05）．Conclusions Compared with chemotherapy alone,immunotherapy combined with chemotherapy can effectively reduce the levels of tumor markers,improve the immune indexes of patients,reduce the adverse drug reactions,and improve the efficacy and quality of life of patients with advanced NSCLC．

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．
