摘要:

目的 分析外周血淋巴细胞形态学分类和淋巴细胞亚群的相关性,探讨其在危重型流行性感冒(简称流感)疗效判断中的价值。方法 选取2018年6月—2024年5月中国人民解放军联勤保障部队910医院收治的142例危重型流感患者(危重型组)和126例流感病毒核酸检测阴性的正常体检者(对照组)。制备血涂片,根据淋巴细胞特征分为甲、乙、丙3种类型。按B淋巴细胞计数和甲类淋巴细胞计数、T淋巴细胞计数和乙类淋巴细胞计数、自然杀伤(NK)细胞计数和丙类淋巴细胞计数分别分为A组、B组、C组。比较各组各项指标差异。采用Pearson相关分析评价外周血淋巴细胞分型的比例与流式细胞的相关性;采用多因素 Logistic回归分析评估流感危重型转化的危险因素。结果 与对照组比较,危重型组乙类淋巴细胞计数减低(P<0.05)。危重型组死亡患者病程中乙类淋巴细胞计数、T淋巴细胞计数持续偏低;危重型组恢复患者病程中乙类淋巴细胞计数、T淋巴细胞计数逐步恢复正常。A组、B组、C组呈正相关(r=0.757,P均<0.01)。T淋巴细胞计数、乙类淋巴细胞计数、B淋巴细胞计数、NK细胞计数、甲类淋巴细胞计数和丙类淋巴细胞计数降低均是危重型流感发生的危险因素(P均<0.05)。结论 淋巴细胞形态学分类和淋巴细胞亚群的相关性较好,危重型流感患者外周血中的乙类淋巴细胞计数持续增高可提示病情好转,持续处于低值则提示预后不良。

Abstract:

Objective To analyze the correlation between peripheral blood lymphocyte morphological classification and lymphocyte subsets,and to investigate its role in the curative effect judgment of critical influenza. Methods From June 2018 to May 2024,142 patients with critical influenza and 126 healthy subjects without influenza infection and with nucleic acid testing negative (control group) admitted to the 910th Hospital of the Joint Logistics Support Force of the People's Liberation Army of China were enrolled. Blood smears were prepared. According to lymphocyte characteristics,lymphocytes were classified into ClassⅠ,Ⅱ and Ⅲ. According to B lymphocyte count,ClassⅠlymphocyte count,T lymphocyte count,ClassⅡ lymphocyte count,natural killer(NK)cell count and ClassⅢ lymphocyte count,they were classified into Group A,Group B and Group C. The differences in various indicators among the groups were compared. Pearson correlation analysis was used to evaluate the correlation between the proportion of peripheral blood lymphocyte classification and flow cytometry. Multivariate Logistic regression analysis was used to assess the risk factors for the conversion of critical influenza. Results Compared with control group,ClassⅡ lymphocyte count in critical influenza group was decreased (P<0.05). ClassⅡand T lymphocyte count in death patients of critical influenza group remained low. The Class Ⅱ and T lymphocyte count in recovered patients of critical influenza group gradually returned to normal. Group A,Group B and Group C showed a positive correlation (r= 0.757,P<0.01). T lymphocyte,ClassⅡ lymphocyte,B lymphocyte,NK cell,ClassⅠlymphocyte and ClassⅢ lymphocyte counts were all risk factors for critical influenza (P<0.05). Conclusions The correlation between lymphocyte morphological classification and lymphocyte subsets is good. In patients with critical influenza,the increase of ClassⅡ lymphocyte count in peripheral blood can indicate improvement of the condition,while low values indicate poor prognosis.
