本研究目的是探讨血清N-聚糖模型在285例丙氨酸转移酶(alanine aminotransferase,ALT)水平正常(<40 U·L^(-1))的慢性乙型肝炎(慢性乙肝)患者中诊断显著肝纤维化和肝硬化的临床意义。入组患者均进行肝组织活检,并使用Ishak评分...本研究目的是探讨血清N-聚糖模型在285例丙氨酸转移酶(alanine aminotransferase,ALT)水平正常(<40 U·L^(-1))的慢性乙型肝炎(慢性乙肝)患者中诊断显著肝纤维化和肝硬化的临床意义。入组患者均进行肝组织活检,并使用Ishak评分系统评估患者肝组织纤维化程度。应用基于DNA测序仪的荧光糖电泳技术检测患者血清N-聚糖图谱,每例患者的血清样本中共鉴定出9个N-聚糖峰。利用机器学习算法,即随机森林(random forest,RF)构建更理想的血清N-聚糖模型,以诊断显著肝纤维化(≥F3)和肝硬化(≥F5),并比较血清N-聚糖模型和其他纤维化标志物的诊断效能。肝组织活检结果显示,有显著肝纤维化和肝硬化患者分别占63.86%(182/285)和16.49%(47/285),有显著炎症患者为4.91%(14/285)。血清N-聚糖RF-A模型具有很好的诊断显著肝纤维化(≥F3)的效能,其受试者工作特征曲线下面积(area under receiver operating characteristic curve,AUROC)为0.94,与肝活检的符合率为90.45%。在诊断肝硬化(≥F5)时,血清N-聚糖RF-B模型的AUROC为0.97,与肝组织活检的符合率为88.94%。血清N-聚糖模型(RF-A和RF-B)的诊断效能优于肝硬度值测量(liver stiffness measurement,LSM)、基于4因子的纤维化指数(fibrosis index based on the four factors,FIB-4)和天冬氨酸转氨酶与血小板比率指数(aspartate aminotransferase-to-platelet ratio index,APRI)。在ALT水平正常的慢性乙肝患者中,血清N-聚糖模型可作为诊断显著肝纤维化或肝硬化的潜在生物标志物。展开更多

The chest wall plays a vital role in protecting the thoracic organs, supporting the respiratory system, and maintaining the shape of the chest. Therefore, any defect or deformity of the chest wall can have significant functional and aesthetic consequences for the patient. The authors present a case report at Kenyatta National Hospital (KNH) of a dyspneic 47-year-old male patient with a right anterolateral chest wall defect post-pneumonectomy previously complicated by bronchopleural fistula. Past attempts at the chest wall reconstruction had utilized the ipsilateral latissimus dorsi muscle, pectoralis major muscle, and the omental pedicled flaps with limited success. A chimeric anterolateral thigh (ALT) perforator-free flap with vastus lateralis (VL) muscle was used to obliterate the post-pneumonectomy intrathoracic dead space and to provide a cutaneous paddle. This case report aims to show the versatility of the ALT flap for chest wall reconstruction to prevent the post-pneumonectomy syndrome associated with tracheal deviation, inspiratory stridor, and exertional dyspnea. In conclusion, chest wall reconstruction with obliteration of intrathoracic dead space post-pneumonectomy is challenging and needs careful planning and execution.展开更多
