简介:报道1例以皮疹为首发症状的T幼稚淋巴细胞白血病(T-PLL)小细胞变异型。患者男,78岁,全身皮肤发疹2周入院。辅助检查结果回报:血常规WBC272.83×109/L,RBC3.19×1012/L,HGB106g/L,PLT46×109/L,肝功能AST56.9U/L,ALT241U/L,骨髓象:淋巴细胞异常增生,占89%,其中幼淋细胞占5.5%,其余均为成熟淋巴细胞,血片分类:淋巴细胞占99%,其中幼淋占12%。体检:肝脏肋下4.0cm,质韧,边缘钝,表面光滑,无压痛;脾脏肋下2.0cm,质韧,边缘钝,表面光滑,无压痛。确诊为:T幼稚淋巴细胞白血病(T-PLL)小细胞变异型。给予CHOP方案化疗,连续5d后病情明显缓解出院,失访。
简介:摘要目的探讨胰岛自身抗体与生化指标在T1DM和T2DM分型诊断中的价值。方法回顾分析我院近年收诊的T1DM21例及T2DM342例,均进行生化指标检测及胰岛素自身抗体检测,观察两组检测指标间的差异。结果T1DM组4种胰岛自身抗体的单独及联合检测的阳性率均显著高于T2DM组(P<0.01),两组的病发年龄、BMI差异明显,生化指标上,两组的FBG、2hPG、HbA1c、TG、HDL-C上均差异明显(P<0.05),TC及LDL-C则无明显差异(P>0.01)。结论T1DM和T2DM在生化指标和胰岛素自身抗体指标上存在着非常明显的差异,2者都具有特异性,2类指标检测对糖尿病1型和2型分型具有非常理想的诊断价值。

简介:摘要肺癌的发生、扩增、浸润、扩散及转移与机体免疫息息相关。机体对肿瘤的免疫以细胞免疫为主,其中T淋巴细胞(以下简称T细胞)直接或间接参与肿瘤发展的各个阶段,包括机体对肿瘤细胞的免疫监视、肿瘤细胞的免疫逃逸作用。本文就T淋巴细胞亚群在肺癌各型病理类型中的研究及临床治疗研究作一综述。
简介:AbstractAdult T-cell leukemia/lymphoma (ATLL) is an aggressive peripheral T-cell lymphoma caused by the human T lymphotropic virus type-1. The skin is affected in approximately half of ATLL patients, and skin lesions may be the first manifestation of the disease. The skin lesions of ATLL are polymorphous, and depend on the type of skin eruption, which makes it possible for doctors to predict the prognosis of the disease based on the characteristics of skin lesions. In this review article, we describe the clinical manifestations and histopathological patterns of skin lesions in ATLL, focus on its diagnostic and prognostic significance, and also summarize the advances in the treatment of ATLL.
简介:AbstractRespiratory viruses are major human pathogens that cause approximately 200 million pneumonia cases annually and induce various comorbidities with chronic obstructive pulmonary disease (COPD), resulting in significant health concerns and economic burdens. Clinical manifestations in respiratory viral infections and inflammations vary from asymptomatic, mild, to severe, depending on host immune cell responses to pathogens and interactions with airway epithelia. We critically review the activation, effector, and regulation of T cells in respiratory virus infections and chronic inflammations associated with COPD. Crosstalk among T cells, innate immune cells, and airway epithelial cells is discussed as essential parts of pathogenesis and protection in viral infections and COPD. We emphasize the specificity of peptide antigens and the functional heterogeneity of conventional CD4+ and CD8+ T cells to shed some light on potential cellular and molecular candidates for the future development of therapeutics and intervention against respiratory viral infections and inflammations.
简介:摘要: 目的 探讨结核感染T细胞斑点试验的临床影响因素 方法 收集2015年7月至2018年7月检测结核感染T细胞斑点试验(T-SPOT)60例诊断肺结核患者,分别从年龄、性别、基础疾病、免疫状态(CD4计数、影像学等方面分析T-SPOT的临床影响因素。结果 男性T-SPOT阳性率低于女,但是无统计学差异;而合并糖尿病患者阳性率明显低于非合并患者,有统计学差异(P<0.05)。 CD4200μl,但差异无统计学差异(P>0.05);A 孔或者 B 孔(T-SPOT数值)不同病变范围的肺结核患者之间比较差异有统计学差异(P<0.05),范围重度者T-SPOT数值明显低于轻、中度者,有统计学差异(P小于0.05)。结论 T-SPOT 受复杂的临床因素影响较小,有很好的灵敏度并且能很好的反应病情严重程度,因此可以广泛的应用于肺结核的诊断及评估。
