RESUMO
Objective:To study the relationship between the dynamic changes of angiopoietin-2 (Ang-2) and surfactant protein D (SP-D) in pediatric acute respiratory distress syndrome (pARDS) and the severity and prognosis of the disease.Methods:Using nested case-control study method, 80 children with pneumonia complicated with pARDS admitted to PICU at Fujian Maternal and Child Health Hospital from June 2018 to May 2021 were selected as pARDS group, and 19 healthy children with corresponding age were selected as control group.According to the oxygenation, the children in pARDS group were divided into three subgroups: mild group (23 cases), moderate group (32 cases) and severe group (25 cases). According to the prognosis at discharge, the children in pARDS group were divided into survival group (67 cases) and death group (13 cases). Ang-2 and SP-D were detected by enzyme-linked immunosorbent assay.The levels of Ang-2 and SP-D in children with pARDS of different severity on the first day were compared; The changes of Ang-2 and SP-D levels on the 1st, 3rd and 8th day of children in survival group and death group were compared, and the receiver operating characteristic (ROC) curve was plotted to compare the predictive value of Ang-2 and SP-D for pARDS prognosis.Results:(1) The levels of Ang-2 and SP-D on the first day in pARDS group were significantly higher than those in control group( P<0.001). (2) The levels of Ang-2 and SP-D on the first day in children with pARDS of different severity levels were significantly different ( P<0.001), and the levels of Ang-2 and SP-D increased gradually with the increase of disease severity.(3) The levels of Ang-2 and SP-D in death group were significantly higher than those in survival group on the 1st, 3rd and 8th day ( P<0.05). (4) Prognostic efficacy of Ang-2 and SP-D levels in pARDS group at different time points: when the areas under the ROC curve predicted by Ang-2 on the 1st, 3rd and 8th day for inpatient mortality in children with pARDS were 0.808, 0.981 and 0.989, respectively; the optimal cut-off values were 6 000 pg/mL, 6 971 pg/mL and 4 171 pg/mL, respectively; the sensitivity was 84.6%, 92.3% and 92.3%, respectively; and the specificity was 76.1%, 97.0% and 98.5%, respectively.The areas under the ROC curve predicted by SP-D on the 1st, 3rd and 8th day for inpatient mortality in children with pARDS were 0.689, 0.993 and 0.983, respectively; the optimal cut-off values were 13544 pg/mL, 16003 pg/mL and 12294 pg/mL, respectively; the sensitivity was 84.6%, 100.0% and 100.0%, respectively; and the specificity was 46.3%, 98.5% and 97.0%, respectively. Conclusion:Serum Ang-2 and SP-D levels in children with pARDS increase with the aggravation of the disease.The dynamic changes of Ang-2 and SP-D in children with pARDS with different prognosis are different during the course of disease, and monitoring serum Ang-2 and SP-D during the course of disease has a certain predictive value for clinical outcome.

<p><b>OBJECTIVE</b>To explore the prevalence and the different risk factors for asthma in children between urban and rural areas in Fuzhou, Fujian province.</p><p><b>METHOD</b>The epidemiological survey of asthma in 0-14 years old children was conducted from October 2009 to October 2010 between Fuzhou urban and rural areas in Fujian province. The investigation subjects were selected in urban and rural areas by phased stratified random cluster sampling. The 2010 third national epidemiological survey questionnaire of children with asthma was used for screening for possible patients. Diagnosis of asthma was confirmed by physical examination. The children with asthma were designated as the positive cases, while non asthmatic children who were age, gender, ethnic, and living environment matched with asthmatic patients were designated as negative control. Comparison of the prevalence of asthma in children between Fuzhou urban and rural areas was performed. The influencing factors of asthma were analyzed and screened by the regression equation model of two element Logistic regression.</p><p><b>RESULT</b>Totally 12 235 questionnaires of children with asthma and allergic disease screening were issued and 11 738 questionnaire were sent back (6 221 were male and 5 517 were female). The return rate was 95.9% in urban Fuzhou; 648 children were diagnosed as asthma. The prevalence of asthma in male was 6.48% and female children was 4.44% (comparison of the prevalence of gender χ(2) = 23.267, P < 0.001) in urban areas . A total of 6 000 questionnaires of children with asthma and allergic disease screening were sent out and 5 860 were responded (male children 3 228, female children 2 632). The recovery rate was 97.7% in rural Fuzhou; 135 children with asthma was diagnosed. The prevalence of asthma in male was 2.73%and female children and was 1.79%. Adding protein supplement before 6 months (OR = 1.908, 95%CI:1.233-2.959), the use of antibiotics in the treatment of asthma (OR = 14.541, 95%CI:8.920-23.705), furniture materials (non wood) (OR = 2.432, 95%CI:1.563-3.785) were the main risk factors of children with asthma in urban.

Objective To improve the understanding of pulmonary mucormycosis by analyzing the clinical manifestations,imaging features,diagnosis,treatment and prognosis of this disease.Methods The clinical data of eight patients diagnosed as pulmonary mucormycosis by histopathologic examination were retrospectively analyzed.Results Eight patients included six males and two females with age from 36 days to 66 years.Underlying conditions covered diabetes (n =4),renal transplantation (n =3),premature (n =1) and long-term corticosteroid treatment in two cases.Imaging manifestations revealed multiple irregular lumps or nodules in three cases,multiple cavities with thick wall in three cases,diffuse lung infiltrate in one case and lung opacities in one case.The diagnoses of seven patients were confirmed by percutaneous needle lung biopsy and the remaining one was diagnosed with fiberoptic bronchoscopy biopsy.Surgery combined with amphotericin B liposome(60 mg/d for three weeks)was applied to one patient who was cured with no recurrence after a 22 month follow-up.Three cases were given amphotericin B liposome (a newborn with 7mg/d for 62 days,the other two 60 mg/d for 31 days and 70 mg/d for 71 days respectively).All had achieved marked response with follow up from 8 to 29 months,but one patient relapsed and died of recurrent lung mucormycosis.The other three patients were treated with itraconazole 400-200 mg/d from 21 days to 1 year with duration of follow up from 1 month to 20 months.One patient was not evaluable due to missing.Two patients relapsed and one died.Conclusion Pulmonary mucormycosis is difficult to diagnose and treat with a high mortality.Percutaneous tranthoracic lung biopsy is a useful diagnostic method.Amphotericin B liposome or itraconazole may be active against mucus.Early control of causes is essential to improve the prognosis and reduce the recurrence in patients with pulmonary mucormycosis.
RESUMO
Objective To investigate the clinical efficacy ofβ-lactam combined with macrolides antibiotics in treatment of severe community-acquired pneumonia (CAP) in children. Methods Children with severe CAP on admission between 2012 February and 2012 April were divided into treatment group and control group. With the same symptom specific supportive treat-ment, the patients in the treatment group were treated with both cefmetazole and azithromycin, while the patients in the control group were treated with cefmetazole alone. The total effective rate, number of days of symptoms and signs disappeared and num-ber of days of hospitalization were observed. Results The total effective rate was 87.8%in the trearment group and 61.3%in the control group with significant difference (P<0.05). Compared with control group, the recovery time of temperature, time of pulmonary rale disappearing and cough retraction were reduced (P<0.05). As well as the number of days of hospitalization was decreased (P<0.05). Conclusions The treatment of severe CAP in children with combination of azithromycin and cefmetazole results in better curative effect. A combined medication ofβ-lactam and macrolides antibiotics may be rational and effective.
