Objective:To explore the prognosis of patients with acute aortic syndrome (AAS) in the real world and to examine the risk factors associated with poor outcomes in AAS.Methods:This is a single-center retrospective study. Patients diagnosed with AAS at Xinqiao Hospital from January 2021 to July 2023 were included. The primary endpoints were all-cause mortality and aorta-related mortality, while the secondary endpoints included stroke, myocardial infarction, secondary interventions, and readmission for any cause. Survival analysis was performed using Kaplan-Meier curves, and risk factors for primary endpoint events were analyzed using multivariate Cox regression.Results:A total of 254 AAS patients, aged (58.9±13.2) years were included in this study. There were 178 cases of aortic dissection, 69 cases of aortic intramural hematoma, and 7 cases of aortic penetrating ulcer. The median follow-up time was 545 days. Seventy-three all-cause deaths occurred among patients with AAS, including 61 aorta-related deaths; 3 strokes, 1 myocardial infarction, 9 secondary surgeries, and 35 readmissions for any cause were observed. Kaplan-Meier curve analysis demonstrated significant differences in all-cause mortality rates based on the Stanford classification, AAS disease classification, eGFR, and albumin levels (all P<0.05), and similar results were also observed in aorta-related death (all P<0.05). Multivariate Cox regression suggested that albumin<35 g/L ( HR=2.372, 95% CI 1.337-4.210, P=0.003), eGFR<90 ml·min -1·1.73 m -2 ( HR=2.457, 95% CI 1.261-4.786, P=0.008), and Stanford type A AAS ( HR=3.420, 95% CI 1.998-5.856, P<0.001) were independent risk factors for all-cause mortality in AAS patients; albumin<35 g/L( HR=2.432, 95% CI 1.295-4.570, P=0.006), eGFR<90 ml·min -1·1.73 m -2( HR=2.523,95% CI 1.243-5.122, P=0.010), and Stanford type A AAS ( HR=3.455,95% CI 1.819-6.564, P<0.001) were independent risk factors for aorta-related mortality in AAS patients. Conclusions:In the real world, the prognosis of patients with AAS remains pessimistic. Patients with type A AAS, renal dysfunction, hypoproteinemia may have a higher risk of poor prognosis.

Objective To investigate the typing profiles of human adenovirus infection among children with severe acute respiratory infection ( SARI ) in Shanghai. Methods A total of 441 nasopharyngeal aspirates ( NPAs) were collected from hospitalized children with SARI in Shanghai Pediatrics Hospital Affiliated Fudan University from June 2013 to March 2014.Human adenovirus was detected by nested PCR followed molecular typing by sequencing.Then the phylogenetic and epidemiological analysis was conducted.Results From 441 hospitalized children with SARI, 51 of samples ( 11.6%, 95%CI:8.6%~14.6%) were detected as HAdV infection.Most of the SARI children with HAdV infection were distributed between 0.5 to 5 years old.Typing data shown that HAdV-B (17 of HAdV-3, 16 of HAdV-7) was most dominant as 64.7%(33/51),followed by HAdV-C as 27.5%(14/51);either HAdV-D (HAdV-8) or HAdV-E ( HAdV-4 ) contained only one case, and HAdV-F ( HAdV-41 ) found in two cases. Conclusion Multiple species( B-F) of HAdVs were circulated among children with SARI in Shanghai, and HAdV-B (HAdV-3, HAdV-7) was the most predominant species of circulation.

Objective To probe the pathogenesis of long bone defects and damage to epiphysis as the result of postoperative infections following fractures in the childhood of patients, and to look for ideal ways to prevent and repair the defects and damages. Methods The treatment of the infected bone defect of a tibia had been continued for one year following fracture in one four-year old patient, and the treatment of the infected bone defect of a humerus had been continued for ten years following fracture in another seven-year old patient, but all the treatments had failed. The injured limbs developed bone infection, bone defect, bone exposure, shortening, and pseudoarthrosis deformities at last. Then the lesions were completely cleaned, and the deformities of the infected bones were corrected in one stage, with reconstruction of the bone and the repair of the wounds by transplantations of fibular free flaps. Results Both fibular free flaps survived in one stage transplantation. The bones of the injured limbs healed half a year after the operations, and weight-bearing and walking functions of the injured limbs recovered as well. Conclusion Transplantation of fibular free flap was an ideal way to treat a long bone defect as a result of postoperative infection following fracture in the childhood. The early appropriate treatment of postoperative infection following fracture is very important to avoid bone and epiphysis damages.
