Bystanders or not?Microglia and lymphocytes in aging and stroke

As the average age of the world population increases,more people will face debilitating aging-associated conditions,including dementia and stroke.Not only does the incidence of these conditions increase with age,but the recovery afterward is often worse in older patients.Researchers and health professionals must unveil and understand the factors behind age-associated diseases to develop a therapy for older patients.Aging causes profound changes in the immune system including the activation of microglia in the brain.Activated microglia promote T lymphocyte transmigration leading to an increase in neuroinflammation,white matter damage,and cognitive impairment in both older humans and rodents.The presence of T and B lymphocytes is observed in the aged brain and correlates with worse stroke outcomes.Preclinical strategies in stroke target either microglia or the lymphocytes or the communications between them to promote functional recovery in aged subjects.In this review,we examine the role of the microglia and T and B lymphocytes in aging and how they contribute to cognitive impairment.Additionally,we provide an important update on the contribution of these cells and their interactions in preclinical aged stroke.

Objective:To study the effects of Rabdosia rubescens combined with neoadjuvant chemotherapy on serum CA199, CEA, CA15-3 levels and T lymphocyte subsets in patients with breast cancer.Methods: A total of 70 patients with breast cancer in our hospital were enrolled as the subjects of this study. The subjects were divided into control group (n=35) and treatment group (n=35) randomly. Patients in the control group were treated with new assistant chemotherapy, while those who were in the treatment group were treated with rabdosia rubescens combined with new assistant chemotherapy. The two groups of patients were treated for 3 periods. The serum CA199, CEA, CA15-3 levels and peripheral blood CD4+, CD8+, CD4+/CD8+ cells of the two groups before and after treatment were compared.Results:There were no significantly differences among the serum CA199, CEA, CA15-3 levels and peripheral blood CD4+, CD8+, CD4+/CD8+ cells of the two groups before treatment. The serum CA199, CEA and CA15-3 levels of the two groups after treatment were significantly lower than those before treatment, besides, the serum CA199, CEA and CA15-3 levels of the treatment group were significantly lower than those of the control group. The peripheral blood CD4+, CD4+/CD8+ cells of the control group after treatment were significantly lower than before treatment, and the peripheral blood CD4+, CD4+/CD8+ cells of the treatment group after treatment were significantly higher than those of the control group.Conclusion:Rabdosia rubescens combined with new assistant chemotherapycan can significantly reduce the serum CA199, CEA and CA15-3 levels, and improve peripheral blood CD4+, CD8+, CD4+/CD8+ levels of patients with breast cancer. It is worthy of clinical application.

GZMB在乳腺癌和乳腺良性肿物患者中的表达及与T淋巴细胞水平的关系研究

目的:探讨颗粒酶B(granzyme B,GZMB)在乳腺癌和乳腺良性肿物患者中的表达及与T淋巴细胞水平的关系。方法:选取2022年1月至2023年8月南阳市第一人民医院收治的乳腺癌患者63例为观察组,根据肿瘤分期分为T_(1)N_(0)M_(0)组、T_(2)N_(0)M_(0)组、T_(2)N_(1)M_(0)组、T_(3)N_(0)M_(0)组及T_(3)N_(1)M_(0)组;选择同期治疗的乳腺良性肿物患者9例为对照组;采用流式细胞仪测定各组GZMB及T淋巴细胞水平;对乳腺癌患者GZMB与T淋巴细胞参数完成相关性分析。结果:观察组乳腺癌患者GZMB水平高于对照组(P<0.05);CD_(3)^(+)、CD_(4)^(+)及CD_(4)^(+)/CD_(8)^(+)水平低于对照组(P<0.05);乳腺癌不同分期下CD_(8)^(+)水平无统计差异(P>0.05);乳腺癌患者中T_(3)N_(1)M_(0)组GZMB水平高于其余4组(P<0.05),CD_(3)^(+)、CD_(4)^(+)及CD_(4)^(+)/CD_(8)^(+)水平低于其余4组(P<0.05);乳腺癌患者分期越高,GZMB水平越高,CD_(3)^(+)、CD_(4)^(+)及CD_(4)^(+)/CD_(8)^(+)水平越低;Pearson相关性结果表明,乳腺癌患者GZMB水平与CD_(3)^(+)、CD_(4)^(+)及CD_(4)^(+)/CD_(8)^(+)水平呈负相关(P<0.05)。结论:GZMB在乳腺癌患者中呈高表达,其表达水平在不同分期中存在差异,且与T淋巴细胞水平存在相关性,可指导临床诊疗。

超声心动图参数及外周血T淋巴细胞亚群、NF-κB、CD64水平预测新生儿败血症预后的价值

【目的】探讨超声心动图参数及外周血T淋巴细胞亚群、核因子-κB(NF-κB)、簇分化抗原64(CD64)水平预测新生儿败血症预后的价值。【方法】选取2020年1月至2023年2月本院收治的95例新生儿败血症,根据预后情况将其分为存活组(n=80)和死亡组(n=15)。比较两组患儿超声心动图参数[左室短轴缩短率(FS)、升主动脉内径(AAO)、左室射血分数(LVEF)]、心肌损伤标志物[肌酸激酶(CK)、肌酸激酶同工酶(CK-MB)]、T淋巴细胞亚群(CD3^(+)、CD4^(+)、CD8^(+))、NF-κB、CD64水平;采用Logistic多因素回归分析新生儿败血症预后不良的相关影响因素;采用受试者工作特征(ROC)曲线分析心电图指标及实验室指标预测新生儿败血症预后的临床价值。【结果】两组患儿肌酸激酶CK、CK-MB水平比较,差异无统计学意义(P>0.05);存活组FS、AAO及LVEF高于死亡组患儿,差异有统计学意义(P<0.05)。两组患儿CD8^(+)水平比较,差异无统计学意义(P>0.05);存活组患儿CD3^(+)、CD4^(+)水平高于死亡组,NF-κB、CD64水平低于死亡组,差异有统计学意义(P<0.05)。两组患儿中性粒细胞与淋巴细胞比值(NLR)、C反应蛋白(CRP)水平比较,差异无统计学意义(P>0.05);存活组患儿白细胞计数(WBC)低于死亡组,差异有统计学意义(P<0.05)。Logistic多因素回归分析显示:FS、LVEF、CD64是影响新生儿败血症预后的相关因素(P<0.05)。FS、LVEF、CD64联合预测新生儿败血症预后的ROC曲线下面积为0.948,明显高于各指标单独预测的0.827、0.895和0.877(P<0.05)。【结论】FS、LVEF联合CD64检测对新生儿败血症预后有良好的预测价值,临床可通过密切监测上述指标及时判断新生儿败血症预后,采取相关干预措施。
