RESUMO
The standardized training of resident doctors is the main form of medical education after graduation. The standardization training of ultrasound doctors was guided by post competence, and was explored from the aspects, such as training target, teaching management, teaching method, teaching mode, and examination means. In this study, we adhered to the tutor responsibility system, and horizontal multi-module and vertical step-by-step teaching modes, made study plans according to local conditions, and improved the assessment system, so as to build a standardized and practical training system for ultrasound residents.
RESUMO
Objective To find out the association between the indicators(pulse concussion lung function test index) of bronchial hyperresponsiveness (BHR) with fractional concentration of exhaled nitric oxide (FeNO) at different control periods among preschool asthmatic children.Methods Totally 74 asthmatic children in the pediatric department of our hospital from April 2015 to February 2017 were enrolled in this study,and 25 children undergoing the lung function and FeNO examination served as the controls,aged 3-5 years old.The cases were divided into three groups according to the standard in 2016 version of the Prevention and Treament Guide of Children Bronchial Asthma:asthma control group(n =26),asthma non-control;group(n =48) and control group (n=25).All data of FeNO,resistance of the respiratory system at 5 Hz(R5),resistance of the respiratory system at 5 Hz (R20),difference of R5 and R20(R5-20),reactance area (AX),reactance of the respiratory system at 5 Hz (X5) and resonant frequency of reactance (Fres) were collected.The FeNO,pulse concussion lung function test value and their association were analyzed.Results (1) The FeNO value of asthma the non-control group was significantly higher than that of the asthma control group and the control group,which were 34.00 ± 18.17,20.23± 11.07 and 28.00± 17.30 respectively.The AX detection value of the asthma non-control group was significantly higher than that of the control group(37.29 ± 15.27 vs.30.17 ± 9.50,P＜0.05).(2)R20 had weak correlation with FeNO in the control group(P＜0.05),while R20 had no correlation with FeNO in the non-control group and control group (P＞0.05).FeNO had no obvious correlation with R5,R520,AX,X5 and Fres in the asthma non-control group,asthma control group and control group(P＞0.05).Conclusion In preschool children with asthma,FeNO can reflect the airway eosinophilic inflammation control,and does not reflect the airway hyperresponsiveness.Thereforeit ie needed to combined with FeNO and IOS indicators (airway hyperresponsiveness index AX,etc.),which can more precisely judge whether asthma being controlled.
RESUMO
Objective To enhance the awareness of diagnose and treatment of venous thrombus in premature infants. MethodsThe clinical features, treatment and prognosis of lower limb vein thrombus in three case of premature infants were retrospectively analyzed.ResultsThree premature infants of gestational age 29-36 weeks were found thrombosis in 1-57 days after birth. One case received peripherally inserted central cathete (PICC). All of three cases had infection signs and trauma. One case received thrombolytic and anticoagulant therapy, one case received high dose thrombolytic therapy, and both of them were treated successfully without bleeding complication. However, another case was deteriorated after giving up treatment.ConclusionsCritically ill premature infants are at high risk of thrombosis. Infection, indwelling tube, thrombophilia constitution, and maternal risk factors were the high risk factors of thrombosis. Early detection, early diagnosis, and effective individualized treatment can improve the prognosis.
