Spectrum and immunophenotyping of 653 patients with B‐cell chronic lymphoproliferative disorders in China: A single‐centre analysis

The incidence of B‐cell chronic lymphoproliferative disorders (B‐CLPDs) is significantly lower in China than that in western countries. There have been studies involving small cohorts with conflicting results regarding the spectrum of B‐CLPDs in China, and the types and immunophenotyping of B‐CLPDs in China remain largely unexplored. We conducted a retrospective analysis of 653 cases of B‐CLPDs seen in our centre from 2011 to 2015. Four‐colour flow cytometry was used to determine the expression of each immunological marker, and the diagnostic values of the immunological markers were also investigated. Chronic lymphocytic leukaemia (CLL) was the most common type of B‐CLPD, which was consistent with that in west countries. However, the proportions of CLL (55.9%), follicular lymphoma (2.6%), and hairy cell leukaemia (0.2%) were lower, while the proportion of lymphoplasmacytic lymphoma/WaldenstrÖm macroglobulinaemia (5.4%) was higher in China, as compared with western countries. With respect to immunophenotypic characteristics, CD23 (31.7%) was more frequently expressed in mantle cell lymphoma (MCL) in our cohort than that in western countries. Immunophenotyping was useful in differentiating MCL from CLL or B‐cell prolymphocytic leukaemia and lymphoplasmacytic lymphoma/WaldenstrÖm macroglobulinaemia from splenic marginal zone lymphoma. CD200 was of better diagnostic performance (accuracy: 94.6%) in differentiating CLL from MCL compared with CD23 (accuracy: 93.3%). Some cases of B‐CPLDs, however, had no definite diagnoses, which were diagnosed as CD5⁺B‐CPLDs unclassified (7.7%) and CD5^?B‐CPLDs unclassified (15.8%). This is the largest study that systematically explores the spectrum and immunophenotyping of B‐CLPDs in Asia, confirming that spectrum of B‐CLPDs in China was different from that in western countries. The immunophenotypic features of B‐CLPDs were similar between China and western countries, although a few disparities exist. Cases with no definite diagnoses warrant further studies in the future.     

树突状细胞对LPAK抗人肝癌细胞的促进作用

目的观察人血树突状细胞（DC）联合LPAK细胞（L）体外抗人肝癌BEL-7402细胞（B）的杀伤效应,并对死亡细胞进行形态学分析.材料和方法LD组为DC＋L＋B,L组为L＋B,二组均采用L：B为5：1和10：1两种放靶比,应用TUNEL法及杀伤细胞检测技术,比较LD和L组的抗肿瘤效应。结果人血DC联合LPAK细胞与单用LPAK细胞的抗肿瘤活性比较,LD组＞L组（P＜0.01）,但二者均能诱导BEL-7402细胞调亡;调亡的肿瘤细胞是TUNEL阳性,在LD组较L组明显增多。结论DC能明显增强LPAK细胞对人肝癌细胞的杀伤活性,但不改变LPAK细胞诱导肿瘤细胞调亡的死亡模式。     

Gli1在鼻咽癌组织中的表达及临床意义

目的:探讨神经胶质瘤相关癌基因1(Gli1)在鼻咽癌组织中的表达及其临床意义.方法:免疫组化方法检测89例鼻咽癌组织及21例正常鼻咽组织中Gli1的表达情况,分析Gli1的表达与与鼻咽癌患者临床病理参数及预后之间的关系.结果:Gli1在鼻咽癌组织的表达水平显著高于正常鼻咽组织(P＜0.01),且Gli1的表达水平与鼻咽癌的T分期、淋巴结转移程度及临床分期显著相关(P＜0.05).此外,Gli1蛋白表达越高,患者的生存时间也明显缩短.结论:Gli1在鼻咽癌组织中呈过表达,可能在鼻咽癌的发生、发展中起重要作用,Gli1有可能成为鼻咽癌治疗的新靶点之一.
