Children aerophagia is a relatively rare functional gastrointestinal disease.Its main clinical manifestations are swallowing air,chronic bloating,belching and increased anal exhaust.Since lack of understanding of children aerophagia in pediatricians,it can be very easily missed or misdiagnosed in clinic.Understanding of the research status about children aerophagia means to pediatric clinical guidance.This review summarizes the causes,clinical manifestation,diagnosis and treatment of children aerophagia.

Objective:To evaluate the safety and efficacy of high-intensity focused ultrasound (HIFU) ablation for the VX2 liver tumor near the hepatic main blood vessels of rabbits by using dosimetry and magnetic resonance imaging (MRI) and by analyzing path-ological changes and survival. Methods:Rabbits with VX2 liver tumor adjacent to the abdominal aorta were divided into the HIFU (n=32) and control groups (n=20). MRI-guided HIFU was employed for the ablation of the liver tumor in the HIFU group. The ablation vol-ume and the energy efficiency factor (EEF) of the 32 ablated rabbits were further analyzed. MRI and pathology were used to compare the changes in the tumor before and after HIFU. The survival of the animals in the HIFU and control groups was also determined. Re-sults: Both pathology and imaging showed that the rabbit liver VX2 tumor adjacent to the abdominal aorta was completely ablated, with an EEF of (25.72±11.40) J/mm3. The survival rate was significantly higher in the HIFU group than in the control group (P<0.05). Conclusion: HIFU ablation is safe and effective in rabbit VX2 liver tumor near the abdominal aorta. This approach significantly in-creases survival.

Objective To optimize the extraction process by determing the volatile oil yield of steam distillation and supercritical CO2 extraction from flowers of Elaeagnus angustifolia L..Methods Orthogonal test was carried out to compare two extraction effects between steam distillation and supercritical CO2 extraction by detecting the extraction ratio from flowers of Elaeagnus angustifolia L..Results Steam distillation time on volatile oil extraction has the greatest impaction,and the best condition of supercritical CO2 extraction was extraction pressure of 20 MPa,extraction temperature of 40 ℃,and flux of CO2 is 10 L/h.Conclusion Compared with steam distillation,supercritical CO2 extraction spends less time,has higher efficiency and less harm to the materiel after extracting.It adapts to batch process and is convenient for subsequent extraction technology.
