Background Aspartate aminotransferase (AST) /alanine aminotransferase (ALT) is a novel indicator to evaluate the prognosis of acute critical illness in recent years. At present, AST/ALT has only been reported to evaluate the prognosis of hemophagocytic lymphohistiocytosis (HLH) in adults, while HLH in children has not been studied. Objective To explore the relationship between AST/ALT and clinical characteristics and its prognostic significance in children with HLH, so as to provide a theoretical basis for early clinical recognition and diagnosis of HLH in children. Methods A total of 128 hospitalized children diagnosed with HLH in the Affiliated Hospital of Zunyi Medical University from January 2013 to May 2022 were selected as the research objects, and the baseline data of children were collected through the electronic medical record system. The children were divided into the T1 group (AST/ALT≤1.57, n=43), T2 group (1.57

Objective: To investigate difference between the appearance and the bony structure in the polysyndactyly of the fifth toe fused with the fourth toe., Methods: From Jan. 2009 to Jan. 2014, 54 patients (65 feet) with polysyndactyly of the fifth toe fused with the fourth toe were treated. The appearance, X-ray and intraoperative finding were recorded and compared to classify the deformity. Then the extra toe was excised and syndactyly was separated. The malalignment and brachydactyly of the sixth toes were corrected simultaneously., Results: According to the bone and joint type, the fifth toes were neoplastic toes without joints in 17 feet, or had poor bony and joint alignment with the sixth toes in 48 feet. So the fifth toes were excised in all the cases. The patients were followed up for 1 month to 4 years. The oblique deformity of sixth toes were corrected completely with improved length., Conclusions: The polysyndactyly of the fifth toe fused with the fourth toe should be classified to design the excised toe (usually fifth toe) and correction procedure. The appearance and bony joint recovery are both important.
