ABSTRACT
Objective:To study the clinical characteristics of ureaplasma urealyticum (UU) infection in preterm infants with gestational age <34 weeks.Methods:From January 2017 to December 2021, premature infants with gestational age <34 weeks admitted to neonatal department of our hospital were enrolled in this prospective cohort study. UU-DNA from respiratory tract samples were examined using quantitative fluorescence polymerase chain reaction method. The infants were assigned into UU (+) group and UU (-) group. Perinatal factors and clinical characteristics were compared between the two groups.Results:A total of 182 preterm infants were enrolled, including 59 cases (32.4%) in UU (+) group and 123 (67.6%) in UU (-) group. UU (+) group had significantly lower gestational age and birth weight and significantly higher incidences of vaginal delivery, premature rupture of membranes (PROM) >18 h and maternal chorioamnionitis than UU (-) group ( P<0.05). Compared with UU (-) group, UU (+) group had significantly higher leucocyte count, neutrophil count and interleukin-6 at 1, 24 and 72 h after birth ( P<0.05). No significant differences existed in C-reactive protein and procalcitonin between the two groups at each time point ( P>0.05). In UU (+) group, the incidences of intrauterine pulmonary infection and bronchopulmonary dysplasia (BPD) were higher and the incidence of respiratory distress syndrome was lower than UU (-) group ( P<0.05). No significant differences existed in the incidences of intraventricular hemorrhage, periventricular leukomalacia, feeding intolerance, necrotizing enterocolitis, retinopathy of prematurity between the two groups ( P>0.0 5). UU (+) group had significantly longer duration of oxygen therapy than UU (-) group ( P<0.05). No significant differences existed in the duration of invasive mechanical ventilation and hospital stay between the two groups ( P>0.05). Conclusions:Preterm infants <34 weeks with positive UU in respiratory tract secretions have higher incidences of vaginal delivery, PROM>18 h and maternal chorioamnionitis. Leukocyte and neutrophil count and interleukin -6 are higher in these infants. They need prolonged oxygen therapy and have increased risks of intrauterine pulmonary infection and BPD.
ABSTRACT
Objective To investigate the effect of Budesonide combined with Salbutamol in treatment of chil-dren with bronchial asthma.Methods 100 cases of children with asthma were randomly divided into conventional therapy group(Group A)50 cases and combined treatment group(Group B)50 cases;Conventional therapy was given to group B and Group A Was givend the conventional therapy puls Budesonide combined with salbutamol treatment,2 times a day.The course of treatment was 10d;The effect of clinical symptom score、clinical recovery and adverse reac-tions in two groups were observed.Results The total efficiency of 47 cases(94.O%) in group A were significantly higher than the B group 36 cases(72.0%)(P<0.05);The index of breathing diffculties、coushing、wheezing、wheezing sustain and sleep satisfaction after treatment were significantly decreased compared with before treatment in two groups(all P<0.01);The time of recovery of breath shortness、cough、asthma、wheezing and therapy hys in group A were less than group B(all P<0.05).Condusion Atomizing inhalation treatment of Bedesonide combined with Sallbutamol was effective to treat children with bronchial asthma.
