RESUMO
Objective To explore the present stage newborn loss of hearing morbidity situation of Guangyang District in Langfang,in order to carry the early intervention.Methods The application distortion product ear sound launch meter 2823 newborns who the women's and children's dispensary is born to Guang Yangqu carries on the hearing to sieve looks up,initially sieves passing about 42 days duplicate not to sieve,duplicate does not deve pass ing,transfers the Langfang mother and child care center to make the ABR inspection,ABR passing has not changed over to the Beijing Colleague Hospital hearing diagnostic center further to inspect.Results Initially sieves the newborn 2823 examples,the diagnosis loss of hearing(light,medium and heavy)8 people,the loss of heating disease incidence rate 2.83‰.Conclusion Guang Yangqu the newborn loss of heating disease incidence rate 2.83‰,the specific weight loss disease incidence rate 1.06‰,through sieves looks up,the newborn loss of heating may the early time discover,the early diagnosis,carries on the early intervention,may enhance the hearing impairment spoken language growth.
RESUMO
The elasticity of the ascending aorta in healthy volunteers and hypertension patients were examined by using quantitative tissue velocity imaging (QTVI), and the age-related change in the ascending aortic elasticity was investigated. The anterior and posterior walls of the ascending aorta were imaged with tissue Doppler method in all the subjects and QTVI was performed. Stable curves were obtained from 173 hypertension patients and 185 healthy adults. The peak early diastolic velocity (V(e)), peak late diastolic velocity (V(a)) and peak systolic velocity (V(s)) were measured. The relation of age with these measures was assessed. The results showed that the elasticity of the ascending aorta was much lower in the hypertension patients than in normal controls (P<0.05), and the elasticity was decreased with age in both groups (P<0.05). Our results suggested that QTVI, a new non-invasive ultrasonic technique, is helpful for the assessment of the aortic elasticity in hypertension patients.
