Objective To explore the effect of immunotherapy combined with chemotherapy on lymphatic immunity and quality of life of patients with advanced non-small cell lung cancer（NSCLC）,and to provide reference for further clinical treatment. 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．

N⁶-甲基腺苷(N⁶-methyladenosine, m⁶A)修饰是真核生物信使 RNA中最丰富的表观遗传修饰,其失调会导致mRNA异常生物学行为如翻译和降解紊乱,从而调控肿瘤发生发展。近期研究表明m⁶A在免疫调控过程中可发挥重要作用,其不仅可调节免疫细胞的活化,还在肿瘤微环境中免疫应答发挥重要调控作用,从而影响免疫治疗效果。越来越多的证据表明m⁶A修饰可能是肿瘤免疫治疗的重要潜在干预靶点。本文阐述了免疫细胞中m⁶A修饰调控及其在肿瘤免疫微环境中相关调节作用,并进一步探讨了靶向m⁶A调控蛋白在肿瘤免疫治疗中的干预策略及潜在治疗价值。

N⁶-methyladenosine (m⁶A) modification is the most abundant epigenetic modification in eukaryotic messenger RNA (messenger RNA). Its dysregulation drives abnormal transcription and translation processes, which promotes the occurrence and development of tumors. Studies have shown that m⁶A modification can regulate the activation of immune cells and their infiltration into the tumor microenvironment (TME), which may affect the efficiency of immunotherapy. Therefore, m⁶A modification may be a potential target for tumor immunotherapy. This paper describes the modification of m⁶A in immune cells and the antitumor immune response associated with TME, and explores the potential therapeutic value of targeting m⁶A regulators in tumor immunotherapy.

目的 探讨早期肠内营养集束治疗对重型颅脑损伤患者营养状态及体液免疫功能的影响。方法 42例重型颅脑损伤患者按病人住院号分为两组,单号延迟普通营养治疗组(PT组,21例),双号早期营养集束治疗组(JS组,21例)。于营养治疗开始的第1、7、14天观察营养相关指标、免疫功能指标和ICU住院时间,采用t检验进行统计分析。结果 ①JS组患者血清白蛋白、前白蛋白、血红蛋白与PT组比较均明显升高,有统计学意义(P＜0.05),且各营养指标较治疗前亦明显升高(P＜0.05)。②JS组患者IgG、IgM、IgA、外周淋巴细胞计数(TLC)与PT组比较均明显升高,有统计学意义(P＜0.05),并且较治疗前均有明显改善(P＜0.05)。③JS组患者在ICU的住院时间比PT组减少约1天,但两组比较无统计学意义(P＞0.05)。结论 重型颅脑损伤可出现营养不良和免疫功能下降,规范的早期肠内营养集束治疗可改善病人营养状况,提高体液免疫功能。

Objective To study the changes in the nutritional status and humoral immunity after early enteral-nutrition bundle treatment in patients with severe traumatic brain injury. Methods 42 patients with severe traumatic brain injury were randomly divided into two groups,i.e. delayed common nutrition group (PT- group,21 cases),and early bundle nutrition group(JS-group,21 cases). All cases were tested at day1, day 7,day 14 of nutrition treatment, for detecting the nutrition related index, humoral immune index and ICU monitoring time, T-test was used for datastatistical analysis. Results ①Compared with PT-group, the serum albumin,prealbumin and hemoglobin in JS-group were significantly higher(P＜0.05), also had significant increase compared with before treatment in JS-group (P＜0.05). ②The serum levels of IgG, IgM, IgA and total lymphocyte count(TLC) were significantly higher in JS-group than those in PT-group(P<0.05), and significantly improved compared with before treatment in JS-group(P＜0.05). ③The ICU monitoring time of patients in JS-group was one-day less than that in PT-group, but there was no statistical significant difference between them(P＞0.05). Conclusion There had malnutrition and immune function decline in the patients with severe traumatic brain injury, in whom early enteral-nutrition bundle treatment can improve nutritional status and enhance the humoral immune function.
