目的研究微小RNA microRNA-99b-5p（miR-99b-5p）对心肌细胞肥大表型的调节作用及机制。方法实时荧光定量PCR（RT-qPCR）检测人心肌组织（包括健康对照者、心力衰竭患者心肌组织）以及横向主动脉缩窄（TAC） 手术小鼠心肌中miR-99b-5p的表达水平。血管紧张素Ⅱ（AngⅡ）处理原代乳小鼠心肌细胞（NMVCs）后，利用鬼笔环肽染色呈现心肌细胞大小，RT-qPCR检测miR-99b-5p表达水平。利用RT-qPCR及蛋白质免疫印迹法检测转染miR-99b-5p mimic对NMVCs中肥大相关基因及成纤维细胞生长因子21（Fgf21）表达的影响。双萤光素酶报告实验验证miR-99b-5p与Fgf21基因3'端非翻译区（3’UTR）的结合作用。利用腺病毒介导在NMVCs中过表达Fgf21及超氧化物歧化酶2（Sod2），并利用小干扰RNA（siRNA）敲低NMVCs中Fgf21和Sod2表达，研究Fgf21/Sod2轴是否介导miR-99b-5p对心肌细胞肥大表型的调节作用。结果MiR-99b-5p在心衰患者心肌组织、TAC术后的小鼠心肌组织及在AngⅡ处理的心肌细胞中均表达上调（ P＜0.01）。MiR-99b-5p可促进NMVCs中与肥大相关基因的表达（ P＜0.01）。双萤光素酶报告基因实验证实miR-99b-5p与Fgf21基因的3’UTR存在结合作用，并且miR-99b-5p可抑制Fgf21及其下游基因Sod2表达（ P＜0.05）。在NMVCs中过表达Fgf21或Sod2均可有效逆转miR-99b-5p的促心肌细胞肥大作用（ P＜0.05）。结论MiR-99b-5p在肥厚心肌中表达增加，并通过Fgf21/Sod2轴发挥促进心肌细胞肥大的作用。

目的探究环形RNA circ_0036176对心肌纤维化表型的调控作用。方法通过RT-qPCR检测人心肌组织（包括18例器官捐赠健康志愿者和28例心力衰竭患者）中circ_0036176及其宿主基因MYO9A的表达水平。利用血管紧张素Ⅱ（Ang-Ⅱ）处理人心房肌成纤维细胞（HAFs），RT-qPCR检测circ_0036176和MYO9A的表达水平。放线菌素D和RNase R处理，鉴定circ_0036176的典型环状结构。使用circ_0036176腺病毒在HAFs中实现充分过表达，mRNA及蛋白水平检测纤维化相关基团的表达差异。利用双萤光素酶报告基因实验和RNA反义纯化技术（RAP）筛选可与circ_0036176有效结合的miRNA。利用C57BL/6乳小鼠心肌成纤维细胞（mCFs）研究miR-218-5p是否介导circ_0036176对心肌纤维化表型的调节作用。结果Circ_0036176在心衰心肌中表达增加（ P＜0.001），但在Ang-Ⅱ诱导的HAFs纤维化细胞模型中，宿主基因及该circRNA的表达一致下调 （ P＜0.01）。放线菌素D和RNase R实验证实circ_0036176具有典型的环形RNA稳定性。在HAFs中充分过表达circ_0036176后，纤维化相关基因表达均有所下降 （ P＜0.05）。双萤光素酶报告基因实验与RAP实验证实miR-218-5p与circ_0036176间存在结合作用。mCFs中转染miR-218-5p促进了纤维化相关基团的表达，并可有效抵抗circ_0036176的纤维化抑制作用。结论Circ_0036176在心衰病人的心肌组织中表达上调，并可通过吸附 miR-218-5p的方式来抑制心肌纤维化。

Objective: To analyze the distribution of pathogenic bacteria in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) combined with ventilator-associated pneumonia (VAP), and to investigate the evaluation value of eosinophils (EOS) and red blood cell distribution width (RDW) combined with clinical pulmonary infection score (CPIS) in prognosis. Methods: 82 patients with AECOPD combined with VAP (VAP group) who were admitted to our hospital from January 2019 to January 2022 were selected, and another 55 patients with AECOPD without VAP (non-VAP group) in the same period were selected. According to the survival of the patients in the VAP group at 28 d after treatment, they were divided into death subgroup with 33 cases and survival subgroup with 49 cases. The levels of peripheral blood EOS and RDW of all patients were detected and CPIS score was calculated, the distribution of pathogenic bacteria in patients with AECOPD combined with VAP were analyzed. Multivariate Logistic regression was used to analyze the influencing factors of poor prognosis in patients with AECOPD combined with VAP. The evaluation value of peripheral blood EOS, RDW and CPIS score in patients with AECOPD combined with VAP was analyzed by receiver operating characteristic (ROC) curve. Results: A total of 89 strains of pathogenic bacteria were detected in 82 patients with AECOPD combined with VAP, and Gram-negative bacteria, Gram-positive bacteria and fungi accounted for 55.06%, 42.70% and 2.25%, respectively. Compared with non-VAP group, the levels of peripheral blood EOS, RDW and CPIS score in VAP group were higher (all p<0.05). Compared with the survival subgroup, the death subgroup had higher peripheral blood EOS, RDW levels and CPI score (all P<0.05). Multivariate Logistic regression analysis showed that the increased of age and the increased of procalcitonin, peripheral blood EOS, RDW levels and CPIS score were independent risk factors for poor prognosis in patients with AECOPD combined with VAP, and the increased of forced expiratory volume in one second to the predicted value (FEV1%) was independent protective factor (all P＜0.05). ROC curve analysis showed that the area under the curve (AUC) of peripheral blood EOS and RDW combined with CPIS score in evaluating the prognosis of patients with AECOPD combined with VAP was greater than that of peripheral blood EOS, RDW and CPIS scores alone. Conclusion: The pathogenic bacteria of patients with AECOPD combined with VAP are mainly gram-negative bacteria. The increased of peripheral blood EOS, RDW, and CPIS score are closely related to the poor prognosis of patients. The combination of the three is of high value in evaluating the prognosis of patients with AECOPD combined with VAP. [ABSTRACT FROM AUTHOR]
