Aims To understand the compliance, influencing factors, and action path of family cardiac rehabilitation exercise prescriptions for children after congenital heart disease surgery. Methods and results A random sampling method was used to select 200 paediatric patients and their parents from a paediatric hospital in Shanghai. Among them, 57 cases (28.5%) of children's families followed the cardiac rehabilitation exercise prescription. Path analysis showed that peak oxygen uptake exerted a negative impact on the compliance of family cardiac-rehabilitation prescriptions for patients after congenital heart disease surgery through doctor–patient trust, with a standardized path coefficient of −0.246 (P = 0.001). Disease-related knowledge exerted a positive effect on the compliance of family cardiac-rehabilitation prescriptions for children after congenital heart surgery through doctor–patient trust, with a standardized path coefficient of 0.353 (P < 0.001). The dimension of friend support in social support had a direct positive effect on the compliance of family cardiac-rehabilitation prescriptions for children after cardiac surgery, with a standardized path coefficient of 0.641 (P = 0.006). Conclusion The compliance of cardiac rehabilitation exercise prescription in children with congenital heart disease is not good and is affected by many factors, and there is a complex path relationship between various factors; the kilogram oxygen consumption of the child, the disease-related knowledge of the caregiver, and social support all play important roles in the compliance of the child's family's health prescription.

A systematic evolution-of-ligands-by-exponential-enrichment study of RNA identifies a high-affinity, high-specificity RNA ligand, F5, that inhibits the feline immunodeficiency virus reverse transcriptase (FIV RT). Ligand F5 can effectively inhibit FIV RT with respect to template-primer, but less effectively with respect to deoxyribonucleoside 5'-triphosphates, indicating that the inhibitory effect is specific for the FIV enzyme.

Single-junction, lattice-mismatched In0.69Ga0.31As thermophotovoltaic (TPV) devices each with a bandgap of 0.6 eV are grown on InP substrate by metal-organic chemical vapour deposition (MOCVD). Compositionally undulating stepgraded InAsyP1-y buffer layers with a lattice mismatch of ∼1.2% are used to mitigate the effect of lattice mismatch between the device layers and the InP substrate. With an optimized buffer thickness, the In0.69Ga0.31As active layers grown on the buffer display a high crystal quality with no measurable tetragonal distortion. High-performance single-junction devices are demonstrated, with an open-circuit voltage of 0.215 V and a photovoltaic conversion efficiency of 6.9% at a short-circuit current density of 47.6 mA/cm², which are measured under the standard solar simulator of air mass 1.5-global (AM 1.5 G).
