Objective: Clinical and genetic mutation analysis was performed on 5 infantile glycogen storage disease type II children in Chinese mainland.
Methods: Clinical data of 5 children with infantile-type glycogen storage disease type II due to the acidic α-glucosidase (GAA) gene variants diagnosed and treated at Hebei Provincial Children's Hospital from January 2018 to April 2020 were retrospectively analyzed.
Results: Among the 5 cases, 1 was female and 4 were male, and the age at first diagnosis was from 2 months to 7 months.
A bimodular material is a kind of material that presents two elastic moduli in tension and compression. In classical thermoelasticity, however, the bimodular material is rarely considered due to its complexity in analysis. In fact, almost all materials will present, more or less, bimodular characteristics, and in some cases, the mechanical properties of materials cannot be fully utilized simply by ignoring the bimodular characteristics.
