RESUMO

OBJECTIVE@#To observe the incidence of malnutrition and nutritional risk in children with pneumonia on mechanical ventilation in the pediatric intensive care unit (PICU), and to explore the nutritional support effect of short-peptide enteral nutrition formula.@*METHODS@#A total of 68 children with severe pneumonia who were hospitalized in the PICU from October 2017 to October 2018 and required mechanical ventilation were enrolled for a prospective randomized controlled study. The children were randomly divided into a control group and an experimental group. Through the nasogastric feeding tube, the experimental group received the short-peptide enteral nutrition formula, and the control group received the intact-protein enteral nutrition formula. The weight-for-age Z score, STRONGkids nutritional risk score, and pediatric critical illness score of the two groups were evaluated. The serum levels of total protein, albumin, and prealbumin (PA) on admission and before discharge were measured. The gastrointestinal tolerance and clinical outcome indicators of the two groups were observed.@*RESULTS@#Among the 68 mechanically ventilated children, 26 (38%) had malnutrition, including moderate malnutrition (10 cases, 15%) and severe malnutrition (16 cases, 24%); 10 cases (15%) had malnutrition at discharge. Sixty-three children (93%) had nutritional risk, including moderate nutritional risk in 21 cases and high nutritional risk in 42 cases. The moderate and high nutritional risk rates of the critical and extreme critical groups were significantly higher than those of the non-critical group (P0.05).@*CONCLUSIONS@#The detection rates of malnutrition and nutritional risk in children with pneumonia on mechanical ventilation are relatively high. Short-peptide enteral nutrition formula can help improve their treatment outcome and are more suitable for nutritional support in critically ill children on mechanical ventilation.

RESUMO

OBJECTIVE@#To investigate the nutritional status of critically ill hospitalized children and to explore the value of nutritional risk screening tools in the nutritional risk assessment.@*METHODS@#The clinical data of 211 critically ill children who were admitted to the pediatric intensive care unit from November 2017 to April 2018 were collected to evaluate their nutritional status on admission and at discharge. Two nutritional risk screening tools, STRONGkids and PYMS, were used for nutritional risk screening in the 211 children.@*RESULTS@#Among the 211 patients, 68 (32.2%) were found to have malnutrition on admission, with 34 cases each of moderate and severe malnutrition. Moderate or high nutritional risk was found in 154 cases (73.0%) with STRONGkids and 165 cases (78.2%) with PYMS. Using weight-for-age Z-score as the gold standard to evaluate the efficacy of the two nutritional risk screening tools, the areas under the receiver operating characteristic curves of STRONGkids and PYMS were 0.822 and 0.759 respectively. Both tools had a significant clinical value in screening for malnutrition (P0.05). With the optimal cut-off value of 3 points, the sensitivities of STRONGkids and PYMS for screening of malnutrition were 92.1% and 76.2% respectively. The children with moderate or high nutritional risk on admission had a significantly poorer prognosis than those with low nutritional risk (P=0.014 and 0.001 respectively). The children with severe malnutrition had a significantly poorer prognosis than those with normal nutrition (P=0.0009).@*CONCLUSIONS@#The detection rates of malnutrition and nutritional risk are high in critically ill children. Malnutrition/high nutritional risk is related to a poor prognosis. Both STRONGkids and PYMS have a clinical value for nutritional risk screening in critically ill children, and they have similar clinical efficacy; however, STRONGkids is more sensitive.

RESUMO

<p><b>OBJECTIVE</b>To investigate the changes in the mRNA and protein expression of high-mobility group box 1 (HMGB1), Toll-like receptor 4 (TLR4), and nuclear factor-kappa B (NF-κB) in lung tissues of asthmatic mice and the interventional effect of vitamin D.</p><p><b>METHODS</b>A total of 48 BALB/c mice were randomly divided into control group, asthma group, and 1,25-(OH)Dintervention group, with 16 mice in each group. An animal model of asthma was established, and lung tissue samples were taken in each group at weeks 1 and 2 of ovalbumin challenging. Conventional hematoxylin-eosin staining was used to measure airway wall thickness. Immunohistochemical staining was used to observe the expression of HMGB1, TLR4, and NF-κB in lung tissues. Quantitative real-time PCR and Western blot were used to investigate the changes in the mRNA and protein expression of HMGB1, TLR4, and NF-κB.</p><p><b>RESULTS</b>At weeks 1 and 2 of ovalbumin challenging, compared with the control group, the asthma group had a significant increase in airway wall thickness and the intervention group had a significant reduction compared with the asthma group (P<0.05). The asthma group had significantly higher mRNA expression of HMGB1, TLR4, and NF-κB in lung tissues than the control group, and the intervention group had significantly lower mRNA expression of TLR4 and NF-κB than the asthma group (P<0.05). At week 1 of ovalbumin challenging, there was no significant difference in the mRNA expression of HMGB1 between the intervention group and the asthma group (P>0.05). At week 2, the intervention group had a significant reduction in the mRNA expression of HMGB1 compared with the asthma group (P<0.05). At weeks 1 and 2 of ovalbumin challenging, the asthma group had significantly higher protein expression of HMGB1, TLR4, and NF-κB in lung tissues than the control group, and the intervention group had significantly lower expression than the asthma group (P<0.05). Airway wall thickness was positively correlated with the mRNA expression of HMGB1, TLR4, and NF-κB in lung tissues (r=0.804, 0.895, and 0.834; P<0.05).</p><p><b>CONCLUSIONS</b>The HMGB1/TLR4/NF-κB signaling pathway plays an important role in the pathogenesis of asthma, and an appropriate amount of 1,25-(OH)Dhas a regulatory effect on this pathway and may prevent the progression of asthma. Therefore, 1,25-(OH)Dis expected to become a new choice for the treatment of asthma.</p>

RESUMO

<p><b>OBJECTIVE</b>To systematically assess the clinical efficacy of high-frequency oscillatory ventilation (HFOV) and conventional mechanical ventilation (CMV) for treating pediatric acute respiratory distress syndrome (ARDS).</p><p><b>METHODS</b>Data from randomized controlled trials comparing HFOV and CMV in the treatment of pediatric ARDS published before July 2016 were collected from the Cochrane Library, PubMed, Medline, CNKI, and Wanfang Data. Literature screening, data extraction, and quality assessment were performed by two independent reviewers according to the inclusion and exclusion criteria. The selected studies were then subjected to a Meta analysis using the RevMan 5.3 software.</p><p><b>RESULTS</b>A total of 6 studies involving 246 patients were included. The results of the Meta analysis showed that there were no significant differences between the HFOV and CMV groups in the in-hospital or 30-day mortality rate, incidence of barotrauma, mean ventilation time, and oxygenation index (P>0.05). However, compared with CMV, HFOV increased the PaO/FiOratio by 17%, 24%, and 31% at 24, 48, and 72 hours after treatment respectively, and improved oxygenation in patients.</p><p><b>CONCLUSIONS</b>Although the mortality rate is not reduced by HFOV in children with ARDS, this treatment can result in significant improvement in oxygenation compared with CMV. Further large-sample, multicenter, randomized clinical trials will be required to draw a definitive conclusion.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the effects of 1,25-(OH)(2)D(3) on airway remodeling and expression of high mobility group box 1 (HMGB1) and IL-17 in asthmatic mice.</p><p><b>METHODS</b>Fifty female mice were randomly divided into 5 groups: control, asthma, low-dose, middle-dose, and high-dose intervention groups (n=10 each). Asthma was induced by intraperitoneal injections of ovalbumin (OVA) and aerosol inhalation of OVA solution. The low-dose, middle-dose, and high-dose intervention groups were administered with 1,25-(OH)(2)D(3) solution at the dosage of 1, 4 and 10 μg/kg respectively by intraperitoneal injections before asthma challenge. The airway structural changes were assessed by hematoxylin and eosin staining. mRNA expression levels of HMGB1 and IL-17 in the lung tissues were evaluated by RT-PCR. The protein levels of HMGB1 and IL-17 in the lung tissues were observed by immunohistochemistry.</p><p><b>RESULTS</b>The airway wall thickness, protein and mRNA expression levels of HMGB1 and IL-17 were higher in the untreated asthma group than in the control group (P<0.05). The airway wall thickness, protein and mRNA expression levels of HMGB1 and IL-17 were lower in the middle-dose and low-dose intervention groups than in the untreated asthma group, and the middle-dose intervention group demonstrated lower airway wall thickness, protein and mRNA expression levels of HMGB1 and IL-17 than in the low-dose intervention group (P<0.05). However, the airway wall thickness, protein and mRNA expression levels of HMGB1 and IL-17 in the high-dose intervention group were higher than in the untreated asthma group (P<0.05).</p><p><b>CONCLUSIONS</b>HMGB1 and IL-17 may be involved in the airway remodeling process in asthmatic mice. A moderate amount of HMGB1 and IL-17 may be involved in the airway remodeling process in asthmatic mice. A moderate amount of 1,25-(OH)(2)D(3) can improve the airway remodeling, but a higher dose of 1,25-(OH)(2)D(3) may affect adversely the airway remodeling process.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the effects of 1,25-(OH)(2)D(3) on the airway remodeling and expression of high-mobility group box 1 (HMGB1) and Toll-like receptor 4 (TLR4) in the lungs among asthmatic mice.</p><p><b>METHODS</b>Thirty female mice (BALB/c strain) were randomly divided into control, asthma and 1,25-(OH)(2)D(3) intervention groups. An asthmatic mouse model was established by intraperitoneal injection and aerosol inhalation of ovalbumin. The intervention group was given 1,25-(OH)(2)D(3) by intraperitoneal injection 0.5 hour before each aerosol inhalation, while the control group used normal saline instead. The hematoxylin-eosin staining was used to observe the mouse airway structural changes. The mRNA and protein expression of HMGB1 and TLR4 was measured by RT-PCR and immunohistochemistry, respectively. Pearson correlation analysis was performed.</p><p><b>RESULTS</b>The asthma group had a significantly increased airway wall thickness compared with the control group (P<0.05); the intervention group had a significantly lower increase in airway wall thickness than the asthma group (P<0.05). The mRNA and protein expression of HMGB1 and TLR4 was significantly higher in the asthma group than in the control group (P<0.05); the mRNA and protein expression of HMGB1 and TLR4 in the intervention group was significantly lower than that in the asthma group, but still higher than that in the control group (P<0.05). A positive correlation was found between the protein expression of HMGB1 and TLR4 (P<0.01), and so was their mRNA expression (P<0.01).</p><p><b>CONCLUSIONS</b>HMGB1 and TLR4 may be involved in asthmatic airway remodeling. 1,25-(OH)(2)D(3) can reduce the airway remodeling in asthmatic mice, which may be related to the downregulation of HMGB1 and TLR4 expression in the lungs of asthmatic mice.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the regulatory role of bacterial lipopolysaccharide (LPS ) in the development of bronchial asthma by examining the effects of LPS on serum IL-4, serum IL-8 and pulmonary vascular endothelial growth factor (VEGF) expression in mice with asthma.</p><p><b>METHODS</b>Twenty-seven BALB/c mice were randomly assigned into control, asthma and LPS-treated asthma groups (n=9 each). Serum IL-4 and IL-8 concentrations were measured using ELISA. VEGF expression in lung tissues was examined using the immunohistochemical method.</p><p><b>RESULTS</b>Serum IL-4 and IL-8 concentrations in the asthma group were significantly higher than in the control group (P<0.05). LPS treatment significantly decreased serum IL-4 and IL-8 concentrations compared with the asthma group (P<0.05), although levels were significantly higher than in the control group (P<0.05). Airway VEGF expression in the asthma group was significantly higher than in the control group (P<0.05). LPS treatment significantly decreased airway VEGF expression compared with the asthma group (P<0.05), although concentrations remained higher than in the control group (P<0.05).</p><p><b>CONCLUSIONS</b>LPS can decrease serum IL-4, serum IL-8 and pulmonary VEGF expression in mice with asthma, and thus can possibly reduce both airway inflammation and airway vascular remodeling.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the value of eosinophils (EOS) and interleukin-17 (IL-17) in nasopharyngeal secretions in the evaluation of progress of wheezing in children under 5 years old.</p><p><b>METHODS</b>Fifty-three children under five years old who had recurrent wheezing were classified into two groups: wheezing group I with atopic body (n=27) and wheezing group II without atopic body (n=26). Twenty pre-surgical children with non-infectious disease were used as the control group. Nasopharyngeal secretions were collected. Inflammatory cells in nasopharyngeal secretions were counted under the microscope. IL-17 levels in supernatants were measured using ELISA.</p><p><b>RESULTS</b>EOS counts in nasopharyngeal secretions in wheezing group I were significantly higher than those in wheezing group II and the control group (p<0.05, p<0.01, respectively). There were no significant differences in EOS counts between wheezing II and the control groups. The IL-17 levels in both wheezing groups were significantly higher than those in the control group (p<0.01), and the wheezing group I had increased IL-17 levels than wheezing group II (1 474+/-974 pg/mL vs 788+/-132 pg/mL; p<0.05). The IL-17 level was positively correlated with the EOS counts in wheezing group I (r=0.62, p<0.05).</p><p><b>CONCLUSIONS</b>EOS counts and IL-17 levels in nasopharyngeal secretions may be used as indices for identifying the tendency to develop asthma in children under 5 years old with wheezing.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the expression of stromal cell derived factor-1(SDF-1) and CXC chemokine receptor 4 (CXCR4) in the airway and the effect of budesonide on their expression in mice with asthma.</p><p><b>METHODS</b>Thirty BALB/c male mices were randomly divided into three groups: placebo control, untreated asthma, and budesonide-treated asthma. The asthma group were induced by intraperitoneal injection of 10% ovalbumin (OVA ) on days 1, 8 and 15, and then from days 22 to 34, challenged by inhalation of 2% OVA aerosol every other day. The budesonide-treated asthma group received an inhalation of budesonide (1 mg ) before OVA challenge. The pathological changes of the airway were assessed by hematoxylin and eosin staining. The immunohistochemistry was used to estimate the expression of SDF-1 in the lung. RT-PCR was used to evaluate the expression of CXCR4 in the lung.</p><p><b>RESULTS</b>Compared with the control group, SDF-1 and CXCR4 expression in the lung in the untreated asthma group increased significantly (p<0.05). The budesonide-treated asthma group demonstrated significantly decreased SDF-1 (0.426+/-0.052 vs 0.361+/-0.065; p<0.05) and CXCR4 (0.829+/-0.027 vs 0.723+/-0.094; p<0.05) expression in the lung as compared with the untreated asthma group. Both SDF-1 (r=0.744, p<0.01) and CXCR4 (r=0.553, p<0.01)were positively correlated with the thickness of the airway wall.</p><p><b>CONCLUSIONS</b>SDF-1 and CXCR4 may be associated with airway remodeling in mice with asthma. Budesonide can improve airway remodeling, possibly by decreasing the expression of SDF-1 and CXCR4.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the effect of dexamethasone on airway morphology and on the expression of angiopoietin-1 (Ang-1) and its tyrosine kinase receptor Tie-2 in the airway of asthmatic rats.</p><p><b>METHODS</b>Forty-five Sprague-Dawley rats were randomly divided into control, asthmatic, and dexamethasone-treated asthmatic groups. Asthma was induced by repeated sensitization and challenge with ovalbumin in the latter two groups. The dexamethasone intervention group received an intraperitonea injection of dexamethasone (2 mg/kg) before asthma challenge. Immunohistochemistry was used to measure the expression of Ang-1 and Tie-2 in the airway. Airway thickness was estimated by a computerized digital image analyzer.</p><p><b>RESULTS</b>Airway thickness in the asthmatic group (33.9333+/-8.3791 micro m2/micro m) increased significantly compared with that in the control group (21.1333+/-2.7740 micro m2/micro m) (P<0.01). The dexamethasone intervention group also showed increased thickness of the airway (27.4000 +/- 4.6105 micro m2/micro m) compared with the control group (P<0.01), but the airway thickness in the dexamethasone intervention group was significantly reduced compared with that in the untreated asthmatic group (P<0.01). The expression of Ang-1 (103.9487+/-8.2914 vs 76.0320+/-3.7728; P<0.01) and Tie-2 (99.2307+/-8.1913 vs 75.3153+/-3.7321; P<0.01) in the airway increased significantly in the asthmatic group compared to controls. The expression of Ang-1 and Tie-2 in the airway of the dexamethasone intervention group (90.6180+/-5.2339 and 86.6633+/-3.7321, respectively) was statistically higher than that in the control group (P<0.01) but statistically lower than that in the untreated asthmatic group (P<0.01). Ang-1 and Tie-2 expression in the airway was positively correlated with the thickness of airway (r(Ang)-1=0.719r(Tie)-2=0.746P<0.01). There was also a positive correlation between Ang-1 and Tie-2 expression (r=0.742P<0.01).</p><p><b>CONCLUSIONS</b>The expression of Ang-1 and Tie-2 in the airway increased in asthmatic rats and was positively correlated with the thickness of the airway. Ang-1 and Tie-2 may participate in the process of airway remodeling in asthma. Dexamethasone can decrease the expression of Ang-1 and Tie-2 in the airway and relieve the changes of airway morphology.</p>

RESUMO

<p><b>OBJECTIVE</b>To study the risk factors for the development of fungal pneumonia in neonates.</p><p><b>METHODS</b>A total of 260 neonates with nosocomial infectious pneumonia were classified into two groups: fungal pneumonia (n=160) and bacterial pneumonia (n=100). Their medical data were retrospectively studied.</p><p><b>RESULTS</b>Eighty-seven percent of patients in the fungal pneumonia group had a duration of hospital stay of >10 days, but 30.1% of patients in the bacterial pneumonia group (p<0.01). The preterm infants in the fungal pneumonia group accounted for 49.5%, which was significantly higher than that in the bacterial pneumonia group (22.0%) (p<0.01). In the fungal pneumonia group, 59.9% of patients showed a weight of <2 500 g, but 34.0% of patients in the bacterial pneumonia group (p<0.01). The duration of the combined use of more than two broad-spectrum antibiotics (p<0.05) and the total duration of antibiotics use in the fungal pneumonia group was significantly longer than that in the bacterial pneumonia group (p<0.05). Nosocomial infectious bacterial pneumonia was common as the primary disease of fungal pneumonia (n=145).</p><p><b>CONCLUSIONS</b>Premature delivery, lower weight, longer duration of hospital stay and antibiotics use, and combined use of more than two broad-spectrum antibiotics may increase the risk of fungal pneumonia in neonates. The development of fungal pneumonia may be related to nosocomial infectious bacterial pneumonia in neonates.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the epidemiological characteristics of pathogens and their antimicrobial susceptibility in neonates with lower respiratory tract infection (LRTI).</p><p><b>METHODS</b>Sputum specimens for bacterial cultures were collected from 1173 neonates with LRTL between January 2005 and December 2006. Antibiotic susceptibility tests were performed after bacteria had been identified.</p><p><b>RESULTS</b>A total of 707 pathogenic strains (60.3%) were identified, including 521 (73.7%) Gram-negative bacilli, 106 (15.0%) Gram-positive bacilli, and 80 (11.3%) fungi. E Coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and enteric bacilli were common cultured Gram-negative bacilli. Most strains of Gram-negative bacilli were susceptible to meropenem, piperacillin/tazobactam, the fourth generation cephalosporin, cebfoperazone/sulbactam and amikacin. Staphylococcus aureus and coagula-negative staphylococci (CNS) were common in the cultured Gram-positive bacilli. Staphylococcus aureus and CNS were susceptible to vancomycin, ciprofloxacin and piperacillin/tazobactam but were resistant to Penicillin.</p><p><b>CONCLUSIONS</b>Gram-negative bacilli predominate the pathogens of LRTI in neonates. E Coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa are major pathogens.</p>

RESUMO

Objective To study the dynamic changes of cytokines including tumor necrosis factor-alpha (TNF-?),interleukin-6 (IL-6),IL-8 in serum and cerebrospinal fluid (CSF) of asphyxia neonates,and to analyze the relationship between cytokines levels and severity of brain damage and neurological outcome. Methods The concentrations of TNF-?,IL-6,IL-8 in serum and CSF were measured by radioimmunoassay in 63 asphyxia neonates. Neurological development was evaluated at 12 months by children′s developmental scale of china.Results The serum concentrations of TNF-?, IL-6,IL-8 were significantly higher in asphyxiated neonates than those in the controls,and they were correlated with the degree of encephalopathy. The level of serum TNF-? was hig-(hest) at the first day and IL-6 was highest at the third day. There was no marked dynamic changes within 5 days in serum IL-8 level. The concentrations of TNF-?,IL-8 in CSF were higher at the first and the third day.The dynamic changes of IL-6 in CSF were similar in serum and they were positively correlated. The serum concentration of IL-6 in severe brain injury group was much higher than those of normal and mild group.The CSF concentration of IL-6 in severe brain injury group was much higher than that of normal group. The CSF concentration of IL-8 in severe brain injury group was much higher than those of the normal and mild group. Conclusions The concentrations of TNF-?,IL-6 and IL-8 are increased both in serum and CSF in asphyxiated neonates which are correlated with severity of hypoxic-ischemic encephalopathy. Cytokine-mediated inflammatory reactions may participate in the mechanism of hypoxic-ischemic brain injury after asphyxiaion.The concentration of IL-6 in serum and IL-6, IL-8 in CSF are correlated with the neurological outcome.
