Objective To explore the clinical characteristics and treatment of infective endocarditis caused by Streptococcus agalactiae．Methods Clinical data and treatment details of a patient with Streptococcus agalactiae endocarditis and acute liver failure admitted to our hospital was analyzed retrospectively．Results After strict anti-biotic therapy and plasmapheresis,the patient received the vegetative removal and valve replacement and finally successfully recovered．Conclusions The diagnosis and treatment of this case suggests that Streptococcus agalactiae infective endocarditis can cause multiple organ dysfunction such as acute heart,liver and renal failure．Optimal timing of surgery and accurate benefits-risk assessment is helpful to improve the prognosis of patients with acute and severe infective endocarditis．

目的 探讨慢性淋巴细胞白血病（CLL）合并第二肿瘤临床特征和预后。方法 回顾性分析2015年8月—2021年10月我院收治的58例CLL患者,其中有11例合并第二肿瘤,47例无合并第二肿瘤,分析两组病例的临床特征及其对预后的影响。结果 CLL合并第二肿瘤和无合并第二肿瘤患者在年龄、性别、白细胞计数、血红蛋白水平、淋巴细胞计数、血小板计数、乳酸脱氢酶（LDH）、β₂-微球蛋白（β₂-MG）水平、分期、单个基因缺失类型之间比较差异无统计学意义,但CLL合并第二肿瘤患者基因缺失个数较无合并第二肿瘤CLL患者组高（χ²=11.17,P=0.03）,且总生存期较短。结论 CLL合并第二肿瘤患者常伴有多个基因缺失,且预后差,当CLL患者伴有多个基因缺失时,在诊治过程中需警惕有无合并第二肿瘤。

Objective To investigate the prognosis and clinical characteristics of chronic lymphocytic leukemia（CLL）patients with second tumor．Methods A retrospective analysis was performed on 58 cases of CLL patients who were diagnosed in our hospital from August 2015 to October 2021．The clinical data of 11 CLL patients with second cancer and 47 CLL patients without second cancer were compared and analyzed．Results There were no significant differences in age,sex,white blood cell count,lymphocyte count,platelet count,the level of serum β₂-microglobulin and lactate dehydrogenase between two groups．However,in CLL patients with second cancer,the incidence of multiple genetic deletions was higher than those without second cancer（χ² =11.17,P =0.03）．The overall survival time was shorter in CLL patients with second primary cancer．Conclusions CLL patients with second tumor have a frequent multiple gene deletions and poor prognosis．Physicians should pay attention to second cancers when diagnosing the CLL patients with multiple gene deletions．

目的 探讨非小细胞肺癌（NSCLC）组织中转化生长因子β激活激酶1（TAK-1）与T细胞因子-4（TCF-4）在 mRNA以及蛋白水平的表达情况及其相关性,并分析两者与NSCLC患者临床病理因素的关系。方法 收集NSCLC手术标本51例,每例均包含肺癌组织及配对癌旁组织,所有患者的术后诊断均经病理结果证实,通过RT-PCR以及Western blot法检测TAK1、TCF-4在癌组织及配对癌旁组织中的表达情况,并通过SPSS进一步分析两者的相关性及其与临床病理因素的关系。结果 TAK1与TCF-4 mRNA以及蛋白水平在NSCLC患者癌组织中均高表达,其中TAK1蛋白的表达与NSCLC的TNM分期（P=0.022）、淋巴结转移（P=0.014）相关,TCF-4蛋白的表达与NSCLC的TNM分期相关（P=0.045）。TAK1在NSCLC组织中的表达与TCF-4呈正相关（r=0.427,P=0.002）。结论 TAK1 mRNA及蛋白水平在NSCLC组织中均高表达,并与TCF-4呈正相关,TAK1有可能成为NSCLC诊断及预后的一个潜在靶标,并且TAK1与TCF-4的联合应用有可能成为一种更为理想的NSCLC辅助诊断及临床治疗方法。

Objective To investigate the mRNA and protein expressions of transforming growth factor β-activated kinase 1（TAK1）and T cell factor-4（TCF-4）in non-small cell lung cancer（NSCLC）tissues and their correlation,and to analyze the relationship between TAK1/TCF-4 and clinicopathological factors in NSCLC patients．Methods Cancer tissues and matched adjacent tissues of 51 NSCLC patients in our hospital were collected．The postoperative diagnosis of all patients was confirmed by pathological results．The expression of TAK1 and TCF-4 in cancer tissues and paired adjacent tissues were detected by RT-PCR and Western blot,then SPSS was used to further analyze the correlation between TAK1 and TCF-4 and clinicopathological factors．Results TAK1 and TCF-4 mRNA and protein were highly expressed in NSCLC tissues,and TAK1 protein expression was significantly correlated with TNM stage of NSCLC（P=0.022）and lymph node metastasis（P=0.014）;TCF-4 protein expression was significantly correlated with TNM stage of NSCLC（P=0.045）．TAK1 expression in NSCLC tissues was positively correlated with TCF-4（r=0.427,P=0.002）．Conclusions TAK1 mRNA and protein were highly expressed in NSCLC tissues and positively correlated with TCF-4．TAK1 may become a potential target for the diagnosis and prognosis of NSCLC,and the combined application of TAK1 and TCF-4 may become a more ideal method for the auxiliary diagnosis and clinical treatment of NSCLC．

目的 介绍1例罕见反转型滤泡性淋巴瘤的诊断、鉴别诊断及文献复习。方法 对1例发生于儿童颈部淋巴结内淋巴瘤进行HE组织形态学、免疫组织化学、荧光原位杂交评估并复习相关文献,进行综合分析。结果 淋巴结结构消失,可见结节状靶环样结构,局灶弥漫。结节中央为非肿瘤性的生发中心（表达CD10、BCL-6,不表达BCL-2及IgD,Ki-67高表达）,紧接着为非肿瘤性套区结构（表达BCL-2及IgD,Ki-67低表达）,最外层为淡染区域,由肿瘤性中心细胞及中心母细胞组成（表达CD10、BCL-6及BCL-2）;局灶弥漫区细胞形态学及其免疫表型同结节状靶环样结构套区外淡染区域。荧光原位杂交未检测到BCL-2基因断裂。结论 本例与文献中报道的反转型滤泡性淋巴瘤（RVFL）有部分相似的特征,但又具有自身的一些特点。

目的 探讨胃癌误诊为环状胰腺并胰腺炎并十二指肠梗阻的原因和治疗。方法 对本院收治的1例由胃癌误诊为环状胰腺并胰腺炎以及十二指肠梗阻患者的临床情况加以总结,并总结复习和分析相关文献。结果 本例患者虽最终明确诊断为胃癌,但病理提示分化差,合并全身多处骨转移,疾病进展迅速,后续放化疗效果欠佳。早期诊断、早期治疗是影响胃癌患者预后的关键。结论 胃癌骨转移的发病率低,极少进行骨转移评估,易造成误诊。当出现胃十二指肠流出道梗阻时,虽患者合并环状胰腺,仍需警惕胃癌的可能,及早完善全身检查,明确诊断,采取正确的治疗措施。
