目的 通过学习1例少见的组织学特征与IgG4相关性淋巴结病类似的浆细胞型特发性多中心型Castleman病（PC-iMCD）,总结两种易误诊疾病的鉴别要点,提高病理诊断水平。方法 回顾性分析1例PC-iMCD患者临床资料,常规苏木素-伊红（HE）染色分析淋巴结组织结构及细胞形态,免疫组织化学染色及原位杂交分析免疫表型及EB病毒（EBV）感染状态,并结合文献分析讨论其与IgG4相关淋巴结病的鉴别诊断。结果 48岁女性患者,临床表现为口干、多饮、皮肤瘙痒伴全身多处淋巴结肿大。实验室检查血清IgG、IgA、IgM及IgE水平均升高,血清IgG4显著升高（14.7 g/L）,白介素- 6（IL-6）异常升高（150.84 pg/mL）。病理检查显示淋巴结生发中心萎缩,套区淋巴细胞呈“洋葱皮”样围绕生发中心排列,滤泡间区扩张,其内见大量成熟的浆细胞呈片状浸润,灶区见含铁血黄素沉积及血管增生;免疫组化染色显示IgG4阳性浆细胞数大于100/高倍视野,IgG4阳性细胞/IgG阳性细胞比值>40%,Kappa及Lambda轻链呈非限制性表达;EB病毒编码RNA原位杂交（EBER）阴性。结论 部分PC-iMCD与IgG4相关淋巴结病具有相似的组织病理学特征,单纯根据组织学及免疫表型难以将两者鉴别,正确诊断需结合IgG4相关病变诊断标准、排除性诊断标准、临床表现及实验室检查综合判断。

Objective By studying a rare case of the plasma cell type idiopathic multicentric Castleman disease（PC-iMCD）with histological characteristics similar to IgG4-related lymphadenopathy,the differential points of the two easily misdiagnosed diseases were summarized to improve the level of pathological diagnosis．Methods The clinical data of one patient with PC-iMCD were collected,the structure alteration and cell morphology were observed by hematoxylin-eosin（HE）stains．The immunophenotype of cells was marked by immunohistochemical staining and the infections status of EB virus was detected by in situ hybridization．Besides,the differential diagnosis between IgG4-RD and PC-iMCD were analyzed and discussed based on literature analysis．Results This article reported a 48-year-old female who was admitted to the hospital with dry mouth,polydipsia,skin itching and multiple lymphadenopathy．The levels of various classes of serum immunoglobulin were all increased,such as IgG,IgA,IgM and IgE．Specially,the serum IgG4 was also significantly increased（14.7 g/L）and interleukin 6（IL-6）was abnormally raised（150.84 pg/mL）．The pathological examination indicated that the lymph node germinal center was atrophied and mantle zones were expanded which were composed of concentric rings of lymphocytes in an “onion skinning” appearance．Besides,the interfollicular area was expanded in which mature plasma cells were infiltrated in sheet-like,hemosiderin was deposited as well as the vessels were proliferated．Immunohistochemistry showed that the number of IgG4-positive plasma cells was >100/HPF,IgG4/IgG-positive cells ratio was >40%,and Kappa and Lambda light chains were expressed unrestrictedly．In situ hybridization revealed that the expression of EBER was negative．Conclusions PC-iMCD and IgG4-related lymphadenopathy shares similar histopathological characteristics and it’s challenging to distinguish these two diseases by their histology and immunophenotype．In conclusion,the correct diagnosis should be combined with the diagnostic criteria,exclusion diagnostic criteria,clinical manifestations and related laboratory examinations．

目的 探索机械通气患者发生呼吸机相关性肺炎（VAP）的危险因素,为医疗机构降低VAP的发生率提供参考依据。方法 采用回顾性病例对照的方法,收集2020年1月—2021年4月入住重症医学科（ICU）接受机械通气>48 h、年龄>18岁的患者资料。根据诊断标准确定20例VAP患者作为病例组,在同期住院患者筛选性别、年龄与病例匹配的20例未发生VAP患者为对照组,并对两组间各项临床指标进行统计分析。结果 两组患者在接受机械通气前入院诊断情况、是否手术和合并慢性阻塞性肺炎、APACHEⅡ评分、置管地点比较差异均无统计学意义（P>0.05）;机械通气时白细胞、C反应蛋白、降钙素原比较差异无统计学意义（P>0.05）。与对照组相比,病例组住院总日数、住ICU天数、机械通气时间、吸痰护理次数、抗生素使用天数明显增加（均P<0.05）。其中ICU中VAP以耐碳青霉烯类鲍曼不动杆菌（占比70%）感染为主;环境卫生学监测发现,患者周围环境、护士站及使用后的消毒物品均检出鲍曼不动杆菌,说明医务人员手卫生依从性差及环境消毒不彻底也是导致院内VAP发生的原因之一。病例组住院总费用中位数为145 207元,对照组为60 745.48元,VAP造成的平均经济损失为84 461.52元/例。病例组各项医疗费用均高于对照组,比较差异有统计学意义（P<0.05）。结论 机械通气期间不适当的诊治、环境消毒不到位、手卫生依从性差可能是造成医疗机构VAP发生的主要原因。

Objective To explore the risk factors of ventilator-associated pneumonia（VAP）in patients with mechanical ventilation,and provide a reference basis for medical institutions to reduce the occurrence of VAP．Methods A retrospective case-control method was used to collect data of patients who hospitalized in intensive care unit（ICU）from January 2020 to April 2021,received mechanical ventilation > 48 h and were >18 years old．According to the diagnostic criteria,20 patients with VAP infection were enrolled as the case group．During the same period,20 non-infected patients who matched sex,age with case group patients were enrolled as the control group,and the clinical indicators between the two groups were statistically analyzed．Results There were no significant differences between the two groups in terms of admission diagnosis,surgery and chronic obstructive pulmonary disease,APACHEII score and place of intubation before mechanical ventilation（P>0.05）．There were no significant differences in white blood cell,C-reactive protein and procalctionin,CRP and PCT during the mechanical ventilation period（P>0.05）．Compared with the control group,the length of stay in hospital,the length of stay in ICU,the time of mechanical ventilation,number of sputum suction nursing,and the days of antibiotic use increased significantly（all P<0.05）．Among them,Acinetobacter baumannii resistant to carbapenem in ICU（accounting for 70%）was the main cause of VAP infection．The environmental hygiene monitoring found that Acinetobacter baumannii was detected in the patient’s surrounding environment,the nurse station and the disinfected items after use,indicating that the low hand hygiene compliance of medical staff and the incomplete disinfection of the environment were also the causes of VAP infection in the hospital．The median of total cost of hospitalization in the case group was 145 207 yuan,while that in the control group was 60 745.48 yuan．The average economic loss caused by VAP infection was 84 461.52 yuan each case．The medical expenses of the case group were higher than those of the control group,with a statistically significant difference（P<0.05）．Conclusions Improper diagnosis and treatment during the mechanical ventilation period,poor environmental disinfection,low hand hygiene compliance of medical staff are probably the main reasons for the occurrence of VAP in this institution．
