Occurrence of the t(2;5)(p23;q35) in non-Hodgkin's lymphoma

Primary CD30(Ki-1)-positive anaplastic large-cell lymphoma (ALCL) is considered by some to be a distinct clinicopathologic entity associated with the t(2;5) (p23;q35). However, the specificity of t(2;5) for ALCL has not been carefully studied. Therefore, we performed a detailed analysis of all cases of ALCL with abnormal cytogenetics results in the Nebraska Lymphoma Study Group registry, as well as all other cases of non-Hodgkin's lymphoma with t(2;5) in the registry. We found the t(2;5) in only five of 10 cases of ALCL, four of whom were young patients. However, we also found the t(2;5) in 11 other cases of nonanaplastic lymphoma, including eight children with typical peripheral T-cell lymphomas of various types. The t(2;5) was also found in three older adults with B-cell lymphomas of various types. Thus, the t(2;5) was not specific for CD30+ ALCL. However, t(2;5) may define a clinicopathologic entity in children and young adults characterized by variable morphologies with a T-cell or indeterminate phenotype, CD30-positivity, nodal disease with frequent extranodal involvement, advanced stage, and an excellent response to therapy, including bone marrow transplantation for relapsed disease. The clinical relevance of the t(2;5) in older patients requires further study.     

肠杆菌科新种细菌的分离鉴定及致病性研究

报告了从辽宁省部分地区腹泻和感染标本中检出的成团肠杆菌、非脱羧勒克氏菌、克吕沃尔氏菌、彭氏变形菌、霍堆氏肠杆菌的分离、鉴定，药敏试验及致病性研究结果．部分菌株可引起动物、生物模型病变，证明有致病力．与人的腹泻和感染有关．致病性研究中，溶血性阳性率最高，依次为乳鼠灌胃，ＨｅＰ—２细胞、Ｖｅｒｏ细胞病变，兔肠袢结扎．豚鼠角膜侵袭试验无阳性．药敏试验证实，５组细菌抗药谱已很广，临床可用的敏感药物不多，一旦发生感染，治疗将十分困难．

深部病原真菌菌种4453株分析

目的 分析深部病原真菌菌种分布。方法 收集1991-2003年我院门诊及住院病人6533例，对其标本按真菌培养分离鉴定步骤进行鉴定。结果 分离出白念珠菌3555株(85．44％)，克柔念珠菌309株(7．43％)，高里念珠菌239株(5．74％)；呼吸系统分离出真菌3004株(68．35％)；消化系统真菌1291株(29．37％)；泌尿生殖系统87株(1．98％)；神经系统8株(0．18％)；血液5株(0．11％)。结论 念珠菌属尤其白念珠菌是我院近13年间系统性真菌感染的重要致病菌；合理应用抗生素及早期诊断尤为重要。     

老年人肱骨近端二部分和三部分移位骨折19例临床分析

目的 探讨老年人肱骨近端二部分和三部分移位骨折的手术治疗方法。方法 回顾性分析19例老年肱骨近端二部分和三部分移位骨折患者的临床资料，其中二部分骨折13例、三部分骨折6例，采用切开复位，肱骨近端解剖钢板固定治疗。结果 二部分骨折术后优良率为76．9％，未出现骨折不愈合及肱骨头坏死；三部分骨折术后优良率为66．7％，肱骨头坏死率16．7％。结论 老年人肱骨近端二部分和三部分骨折应尽量采用有限切开复位，选择肱骨近端解剖钢板固定。
