Objective To evaluate the impact of the asthma education and management model developed by Peking University People's Hospital on the level of asthma control. Methods Trained respiratory physicians from 6 large teaching hospitals in the urban districts of Beijing conducted a successive questionnaire survey in the form of face-to-face interviews with adult asthma patients attending their respective clinics. The results were used to compare the levels of asthma control between patients who were administered "three-in-one" asthma education and management (education group) and those who were not(control group). Results Among the 100 patients in the education group, 85% showed asthma control test(ACT) values ≥20 points. This was significantly higher than that in the 427 control group patients (37%,χ2 =74.345 ,P <0.01 ). During the past 1 year, the rate of hospitalization due to exacerbation of asthma,number of emergency treatments, and missed working days were significantly lower in the education group than in the control group ( 4%, 18%, 20% vs 23%, 32%, 55%, respectively; χ2 = 19.431,7.515 and 17.853 respectively; and P < 0.01 for all). Conclusion The " three-in-one" asthma education and management model can significantly improve asthma control.

Feeding difficulty is a widespread problem with high incidence in the premature infant and small for gestational age. There are many factors to impact the feeding difficulty in premature and small for ges-tational age,including suffocation,primary disease,gestational age,milk time,pregnancy factors,environmental factors,hormone levels. In this paper,we summarize the feeding difficulties′ etiology,pathogenesis,treatment a-bout premature and small for gestational age,aimed at providing the basis of feeding difficulties′prevention and cure for premature and small for gestational age.

Laryngeal cartilage dysplasia,also known as congenital laryngeal cartilage softening or con-genital laryngeal stridor,a clinical common laryngeal disease in infant. It is often shown as airflow makes special sound through larynx or tracheal stenosis,also known as laryngeal stridor. Obstruction can be caused by airway lumen or external pressure. Airway obstruction position can be located in the nose,pharynx and larynx and tra-chea. Laryngeal stridor can be caused by many diseases,such as congenital laryngeal stridor,acute laryngeal,or acute laryngotracheobronchitis,respiratory tract foreign bodies,congenital laryngeal stenosis and laryngeal web, etc. The pathogenesis,pathology,clinical manifestation,diagnosis and treatment are reviewed.

Objective To explore the effect of ultrasound in the diagnosis and treatment of rheumatoid arthritis .Methods though early diagnose of RA by ultrasound ,DAS28 and MRI′s result to measure the accuracy of ultrasound test .then though the ul‐trasound index at different time point in the treatment of RA patients ,we knew the changes of the joint ,and provide treatment plan and prognosis .Results ultrasound had high accuracy rate in the diagnoses of RA(P< 0 .05) ,and there were correlation among ul‐trasound diagnoses accuracy and DAS28 and MRI score(r= 0 .859 ,P< 0 .05) ;at the same time ,it provided accurate changes of the joint during the treatment ,and provided basis for treatment .Conclusion Ultrasound has manifest advantageous in diagnose RA .It could be used as a method in early diagnose RA and evaluate the effect on RA′s treatment .

OBJECTIVETo study the correlation between serum insulin-like growth factor-1 (IGF-1) level and feeding difficulties in preterm infants.

METHODSA retrospective analysis was performed on 200 preterm infants born between January 2013 and January 2014. Venous blood samples were obtained within 24 hours after birth to determine the serum level of IGF-1. The correlation between IGF-1 level and feeding difficulties in preterm infants was analyzed by single-factor analysis and multivariate logistic regression analysis.

RESULTSThe serum IGF-1 level in the feeding difficulty group was significantly lower than that in the control group (28±4 ng/mL vs 63±8 ng/mL; P<0.05). Results of multivariate logistic regression analysis showed that high gestational age and birth weight were protective factors for feeding difficulties in preterm infants, whereas asphyxia, delayed initiation of feeding, use of aminophylline, perinatal infection and decreased IGF-1 level were risk factors.

CONCLUSIONSThe level of serum IGF-1 is correlated with feeding difficulties in premature infants. A reduced IGF-1 level increases the risk of feeding difficulties.

OBJECTIVETo study the pathogens, drug sensitivity and risk factors for ventilator-associated pneumonia (VAP) in neonates.

METHODSRetrospective analysis was performed on the clinical data of 401 neonates who were admitted to the neonatal intensive care unit and received mechanical ventilation for 48 hours or longer from January 2008 to February 2012. Eighty-five of the 401 neonates suffered VAP.

RESULTSThe main pathogens for VAP were Gram-negative bacteria (97%), including Klebsiella pneumoniae (51%), Acinetobacter baumannii (17%) and Escherichia coli (12%) as the three most frequent ones. The drug sensitivity test showed that these pathogens developed resistance to amoxicillin, amoxicillin/clavulanic acid, piperacillin, ceftazidime, cefazolin, and cefotaxime, with a susceptibility rate of below 15%, and demonstrated decreased sensitivity to imipenem and meropenem, with a susceptibility rate of below 75%. The independent risk factors for neonatal VAP included birth weight (OR=1.399, P<0.05), duration of mechanical ventilation (OR=1.966, P<0.01), length of hospital stay (OR=1.812, P<0.01), times of tracheal intubation (OR=2.056, P<0.01), and 1 min Apgar score (OR=2.146, P<0.01).

CONCLUSIONSThe incidence of neonatal VAP is influenced by many factors. The main pathogens for neonatal VAP are Gram-negative bacteria and antibacterial agents should be properly used according to drug sensitivity test results. Comprehensive prevention and control measures should be taken to reduce the incidence of VAP.

Objective To investigate the status on children of 3-14 years old who suffered from cerebral palsy in Liaoning province. Methods One thousand three hundred and twenty-three cases of children with cerebral palsy of 3-14 years old who received rehabilitation in city hospital, county hospital and community hospital were investigated from January 2013 to October 2016 in 14 cities in Liaoning Province. The proportion of cerebral palsy children in 3-4 years old, 4-5 years old, 8-9 years old, 5-6 years old , 6-7 years old and 7-8 years old was about 10%, and in the other age the proportion was about 7%. The proportion of men and women generally was 4:1;neonatal convulsion (252 cases, 19%), premature delivery (230 cases , 17.3%) and low birth weight infant (187 cases, 14.1%) were main risk factors and accounted for more than 10%. Spastic type cerebral palsy accounted for the highest proportion (54.35%, 719 cases)and ataxia cerebral palsy accounted for the lowest proportion (2.95%). In complications , lower intelligence accounted for the highest proportion (50.34%, 666 cases), followed by the language barrier (43.99% , 582 cases), and the other complications accounted for less than 10%.;gross motor function classification in most studied children was stageⅡ(35%) and stageⅢ(32.50%); 6.95% patients could go to school, and 84.96% patients had health insurance. Patients coming from city accounted for 69.01%, and patients coming from rural area accounted for 30.99%. Mothers′ education below primary school was 4.16% . 36.05% children received rehabilitation in comprehensive hospital, 60.09%in children′s hospital and 3.85%in maternal and child health hospital. Conclusions Spastic cerebral palsy is the main type of children with cerebral palsy in Liaoning.High risk factors include neonatal convulsions, premature birth and low birth weight infants. Most patients complicate with low intelligence and language barriers.This paper can be used as the basis of further research on prevention and treatment

The application of electronic informed consent has the advantages of speeding up the recruitment of subjects, helping the less educated to understand research and recruit groups, facilitating direct communication between subjects and researchers, minimizing human omissions and errors, and effectively improving the efficiency of clinical research. However, there are also some challenges, such as privacy, ethical censorship, hardware costs and so on. On the basis of the above discussion, this paper believed that electronic informed consent, as a new form, would provide a more powerful tool for clinical research in an era full of opportunities and challenges, with research value and potential.
