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．

腺苷至肌苷RNA编辑（AIRE）是指转录前体RNA在腺苷酸脱氨酶的作用下,某些位点的腺苷发生脱氨反应转变成肌苷的过程,在碱基配对时,肌苷被识别作鸟苷,导致转录组重编写。随着高通量测序技术的不断进步,大量异常的AIRE被发现可导致氨基酸编码改变、RNA剪切异常以及microRNA-mRNA重定向等过程,从而参与肿瘤的发生发展。绝大部分的AIRE位点均位于基因非编码区,解析它们的生物学功能仍存在一定的挑战。本综述旨在描述AIRE的生物学机制和AIRE位点在不同肿瘤发生发展作用的进展,为AIRE与肿瘤的研究提供思路。

Adenosine-to-inosine RNA editing（AIRE）is catalysed by adenosine deaminases acting on RNA（ADARs）,which converts adenosine to inosine in nascent RNA．Since inosine is recognized as guanosine in post-transcriptional process,AIRE is functionally approximate to an A-to-G mutation and results in transcriptome recoding．With the continuous advancement of high-throughput sequencing technology,a large number of abnormal AIRE events have been found to exert different biological mechanisms such as amino acid changes,RNA splicing abnormalities and microRNA-mRNA redirection,which plays an important role in the development of human tumorigenesis．Most of AIRE sites are located in non-coding region,which brings challenges in analyzing their biological functions．This review aims to describe the biological mechanisms of AIRE and the relationship between AIRE sites and the development of different tumor types,providing ideas for the study of AIRE and tumors．

目的 探讨子宫内膜异位症（EMT）患者卵泡液来源的外泌体差异微小RNA（miRNA）对卵母细胞质量的影响。方法 收集2021年12月—2022年3月在广州市第一人民医院生殖医学中心进行体外受精-胚胎移植/卵细胞浆内单精子注射助孕的20例不孕症患者的卵泡液,分为EMT组（EMT不孕症患者10例）和对照组（单纯男性因素不孕症患者10例）。采用高通量测序对卵泡液外泌体微小RNA（miRNA）谱进行分析,选出具有组间差异的miRNAs。结果 与单纯男性因素不孕患者相比,EMT组有18个外泌体miRNAs差异有统计学意义,其中上调9个、下调9个。靶基因预测并采用GO和KEGG富集分析发现,这些靶基因主要参与磷脂酰肌醇-3-激酶/蛋白激酶B（ PI3K-Akt）、核苷酸结合寡聚结构域NOD样受体、Ras等信号通路。结论 EMT患者卵泡液来源的外泌体miRNA存在差异,差异的外泌体miRNAs可能通过多个信号通路影响EMT患者卵母细胞质量。

Objective To investigate the effect of differential microRNA（miRNA）derived from follicular fluid exosomes on oocyte quality in patients with endometriosis（EMT）. Methods Follicular fluid was collected from 20 infertile patients undergoing IVF-ET / ICSI in the Reproductive Medicine Center of Guangzhou First People's Hospital from December 2021 to March 2022,including EMT group（10 patients with EMT infertility）and control group（10 patients with simple male factor infertility）．The miRNA spectrum in follicular fluid exosomes was analyzed by high-throughput sequencing and miRNAs with differences between groups were selected. Results Compared with patients with infertility due to simple male factors,there were significant differences in 18 exosomal miRNAs in the EMT group,of which 9 were up-regulated and 9 were down-regulated．GO and KEGG enrichment analysis showed that these target genes were mainly involved in phosphatidylinositol-3-kinase / protein kinase B,Nucleotide binding oligomerization domain-like receptor and other signaling pathways. Conclusions There are differences in follicular fluid-derived exosomal miRNAs in EMT patients．Differential exosomal miRNAs may affect oocyte quality in EMT patients through multiple signaling pathways．
