ABSTRACT
Objective:To analyze the difference of clinical characteristics and outcomes of infants with moderate and severe pediatric acute respiratory distress syndrome(PARDS)diagnosed according to baseline oxygenation index(OI) in pediatric intensive care unit(PICU).Methods:Second analysis of the data collected from the "Efficacy of pulmonary surfactant (PS) in the treatment of children with moderate and severe ARDS" program.Retrospectively compare of the differences in clinical data such as general condition, underlying diseases, OI, mechanical ventilation, PS administration and outcomes among infants with moderate and severe PARDS divided by baseline OI who admitted to PICUs at 14 participating tertiary hospitals from 2016 to December 2021.Results:Among the 101 cases, 55 cases (54.5%) were moderate and 46 cases (45.5%) were severe PARDS.The proportion of male in the severe group (50.0% vs.72.7%, P=0.019) and the pediatric critical illness score(PCIS)[72 (68, 78) vs.76 (70, 80), P=0.019] were significantly lower than those in the moderate group, while there was no significant difference regarding age, body weight, etiology of PARDS and underlying diseases.The utilization rate of high-frequency ventilator in the severe group was significantly higher than that in the moderate group (34.8% vs.10.9%, P=0.004), but there was no significant difference in PS use, fluid load and pulmonary complications.The 24 h OI improvement (0.26±0.33 vs.0.04±0.34, P=0.001) and the 72 h OI improvement[0.34 (-0.04, 0.62) vs.0.15 (-0.14, 0.42), P=0.029)]in the severe group were significantly better than those in the moderate group, but there was no significant difference regarding mortality, length of hospital stay and intubation duration after diagnosis of PARDS between the two groups. Conclusion:In moderate and severe(divided by baseline OI) PARDS infants with invasive mechanical ventilation, children in severe group have better oxygenation improvement in the early stage after PARDS identified and are more likely to receive high frequency ventilation compared to those in moderate group.Baseline OI can not sensitively distinguish the outcomes and is not an ideal index for PARDS grading of this kind of patient.
ABSTRACT
Clq/tumor necrosis factor related proteins(CTRPs)are a newly discovered superfamily of proteins with wide tissue distribution and diverse biological functions, which are involved in the regulation of glucose and lipid metabolism, vascular endothelial cell function and inflammatory response.There are few studies on the relationship between CTRP family and sepsis, and a few studies have shown that some CTRP family members are involved in the occurrence and development of sepsis.This review introduced the role of CTRP family in sepsis and related mechanism.

ABSTRACT
Hyperglycemia, hypoglycemia, and even glucose metabolism crisis and cerebral edema are common complications in critically ill children with glucose metabolism disorders.In clinical practice, blood glucose monitoring should be strengthened.When glucose is abnormal, it should be treated in time to control it within the normal range and reduce complications.This review elucidated and discussed the diagnosis of hyperglycemia and hypoglycemia, blood glucose monitoring, glycemic target and treatment scheme for abnormal glucose metabolism in critically ill children to provide suggestions for blood glucose management in pediatric intensive care unit.
ABSTRACT
Fluid overload is frequently found in critically ill patients with pediatric heart failure.Volume management is one of the important therapeutic measures for pediatric patients with heart failure, the aim of which is to achieve the best individual volume homeostasis.Assessment of volume status is the premise and foundation of volume management.The comprehensive evaluation and effective management of volume status leave clinical doctors a great challenge.In order to provide guidance and evidence for clinicians, this review elucidated the methods for assessment and management of volume status for pediatric patients with heart failure.
ABSTRACT
Blood adsorption, one of the blood purification, can be classified into hemoperfusion and immunoadsorption.In recent years, double plasma molecular adsorption, a combined adsorption, has also been widely used in clinical practice.Based on adsorption, the toxins in blood of patients can be efficiently removed by hemoadsorbents.There are two kinds of adsorbents commonly used in hemoperfusion: carbon and resin, and two types of adsorbents in immunoadsorption: biological affinity and physicochemical affinity.Adsorption has been widely applied in clinical practice, involving in sepsis, organ transplantation, systemic lupus erythematosus, liver failure, autoimmune diseases and so on.The review described the application of blood adsorption in clinical practice.
ABSTRACT
Objective:Through the establishment and preliminary application of standardized, real-time and online database of severe sepsis in children, we can realize the information about management of children with severe sepsis, providing data to support scientific research and clinical work, and building a homogeneous scientific research and clinical platform for multiple units participating in constructing the database.Methods:We designed, developed and established an online database system for children with severe sepsis, which was filled in in real time by 19 member units of Diagnosis and Treatment Collaboration Group for Sepsis in Children in Shandong Province.The basic information, treatment and prognosis of children entered in the database were preliminarily analyzed.Results:(1)A real-time online disease-specific database for severe sepsis in children was established primarily, with the classification, storage, logical retrieval, statistical analysis and map-making of the information of children with severe sepsis.(2)Further analysis was conducted on the clinical data of 602 children with severe sepsis, which had been recorded in the database.There were 341 males(56.6%)and 261 females(43.4%). The median age was 16 months.There were 230(38.2%)children younger than 1 year old, and 274 children aged from 1 to 5 years old(45.5%), 98 children(16.3%)were 6 years old and above.Three hundred and forty-three cases(57.0%)were from rural areas.One hundred and eighty-one cases(30.1%)were found to have basic diseases.The primary site of infection was the respiratory system(40.8%). The in-hospital mortality was 15.6% in children with severe sepsis.Multivariate Logistic regression analysis showed that high pediatric risk of mortality score Ⅲ score at 24 hours after admission, acute respiratory distress syndrome, acute renal injury, mechanical ventilation and vasoactive drug treatment were independent risk factors for in-hospital death in children with severe sepsis( P<0.05). Conclusion:The disease-specific database of severe sepsis in children can provide data for scientific research and clinical practice of sepsis management in children, and contribute to the formulation and improvement of clinical decision-making in the future.Simultaneously, it has also constructed a homogeneous scientific research and clinical work platform, which may contribute to the common development of the participatory units.
ABSTRACT
Objective:To understand the status of sedation and analgesia treatment and management in pediatric intensive care unit(PICU) in Shandong Province, and to provide the basis for the improvement of sedation and analgesia treatment plan.Methods:This study was a multi-center retrospective study.The PICUs of 6 tertiary hospitals in Shandong Province participated in this study.The data of 1 340 children admitted to these 6 PICUs from January 2016 to December 2018 were collected.The age, gender, the pediatric risk of mortality score Ⅲ at 24 hours after admission, whether they received mechanical ventilation, whether they received sedation and(or) analgesia, whether they were monitored sedation and(or) analgesia, and in-hospital mortality were analyzed.The children were divided into the simple sedation group( n=798), the sedation + analgesia group( n=120) and the non-sedation analgesia group( n=422) according to whether they received sedation and(or) analgesia.The diseases, proportion of mechanical ventilation, incidence of hypotension, average length of stay in PICU and in-hospital mortality were compared among the three groups. Results:The median age of the 1 340 children was (13.3±6.4) months, including 786 males(58.7%). Sedation therapy had been carried out in 6 PICUs, of which 5 PICUs had routine sedation assessment; 4 PICUs had carried out analgesic therapy, of which only 2 had routine pain assessment.A total of 918 children(68.5%)received sedation and(or) analgesia, midazolam was the most commonly used sedative drug, followed by dexmedetomidine, and 526 children(57.3%)were monitored for sedation assessment, the most commonly used assessment method was the Richmond agitation sedation score.One hundred and twenty(9.0%)cases received sedation combined with analgesia, fentanyl was the most commonly used analgesic, and 38 children(31.7%) underwent routine pain assessment.There was no significant difference in age and sex among the three groups.The proportion of surgical diseases and patients received mechanical ventilation(100.0%, 120/120) were the highest in the sedation + analgesia group.The proportion of mechanically ventilated patients was the lowest in the non-sedation analgesia group(11.4%, 48/422). The mean duration of mechanical ventilation in the sedation + analgesia group was slightly shorter than that in the simple sedation group( P>0.05). The incidence of hypotension was highest in the sedation + analgesia group, and lowest in the non-sedation analgesia group[21.7%(26/120) vs.2.1%(9/422), P<0.01]. There was no significant difference in in-hospital mortality and mean PICU stay among three groups. Conclusion:Benzodiazepines are still the main sedative drugs used in PICUs in Shandong Province.In recent years, the usage of dexmedetomidine has gradually increased, but the proportion of analgesic use is very low.At present, analgesic and sedative therapy is mainly used for children after surgery and receiving mechanical ventilation.Although analgesic and sedative therapy does not increase the in-hospital mortality and average length of stay in PICU, it increases the incidence of hypotension.The sedative and analgesic treatment and assessment in the PICU of Shandong Province are still not standardized, mainly reflected in infrequently analgesic treatment and the assessment of sedation and pain, which need to be further improved.
ABSTRACT
Objective:To analyze the epidemiological characteristics of acute paraquat(PQ)poisoning in children in southwest Shandong, and the risk factors for pulmonary interstitial fibrosis.Methods:This retrospective study was performed on the clinical data of children with acute PQ poisoning admitted from January 2013 to December 2017 in 12 hospitals in southwest Shandong.All participants were divided into pulmonary interstitial fibrosis group and no pulmonary interstitial fibrosis group on the basis of the chest CT 14 days after poisoning.The epidemiological characteristics and risk factors of pulmonary interstitial fibrosis were analyzed.Results:During the study period, a total of 307 children with acute PQ poisoning were admitted to 12 hospitals, of which 61 (19.87%) were suffering from acute PQ poisoning.Forty-nine cases with complete clinical data were analyzed, including 26 male and 23 female patients poisoned by oral.The age distribution ranged from 8 months to 14 years.Poisoning mainly occured from July to September of each year.The mortality of acute PQ poisoning was 8.2%(4/49), and the incidence of pulmonary interstitial fibrosis in survival patients was 44.4%(20/45). Statistical differences ( P<0.05) were found between the pulmonary interstitial fibrosis and no pulmonary interstitial fibrosis, with regard to the times of blood purification, the time from poison exposure to blood purification, the application rate of glucocorticoids, the concentration of PQ in urine, the pediatric critical illness score, the time from poison exposure to gastric lavage, the white blood count at admission, serum creatinine, arterial blood lactate, PaO 2, PaCO 2, and PaO 2/FiO 2; however, there was no significant difference in the proportion of blood purification treatment, the mode of blood purification treatment, alanine aminotransferase, aspartate aminotransferase, urea nitrogen, creatine kinase and troponin.Stepwise logistic regression analysis showed that the time from exposure to poison to gastric lavage( OR=0.683, 95% CI 0.210-2.222)and to blood purification( OR=0.0133, 95% CI 0.004-0.042), the times of blood purification( OR=2.862, 95% CI 1.450-5.648), concentration of PQ in urine( OR=1.435, 95% CI 1.085-1.898), and the use of glucocorticoids( OR=0.190, 95% CI 0.048-0.757) were the risk factors for pulmonary interstitial fibrosis( P<0.05). Conclusion:Early gastric lavage and blood purification, increasing the frequence of adminitrating purification appropriately, using low-dose glucocorticoids can reduce the incidence of pulmonary interstitial fibrosis of children with acute PQ poisoning.

ABSTRACT
Sepsis, a systemic inflammatory response syndrome caused by infection, is a common cause of death in ICU patients.Current studies suggest that patients with sepsis have stress-induced hyperglycemia, of which insulin resistance is a direct cause.During sepsis, many factors such as increased hormone release, excessive release of inflammatory mediators and lipogenic factors, oxidative stress, and endoplasmic reticulum stress, lead to the development of insulin resistance by hindering insulin signaling and reducing insulin sensitivity.This article elaborated the mechanism of insulin resistance in sepsis from the above aspects.

ABSTRACT
Objective@#To survey the conduction and evaluate the effectiveness of extracorporeal membrane oxygenation (ECMO) therapy in pediatric intensive care unit (PICU) in China mainland.@*Methods@#In a questionnaire-based survey, we retrospectively reviewed the application of ECMO in children's hospital and general hospital in China mainland to summarize and analyze the categories of diseases and prognosis of children treated with ECMO therapy.@*Results@#By December 31, 2017, a total of 23 hospitals using ECMO, including 22 tertiary referral hospitals and 1 secondary hospital, among which 16 were children′s hospitals and 7 were general hospitals. Thirty-seven ECMO equipment was available. A total of 518 patients treated with ECMO, within whom 323 (62.4%) successfully weaned from ECMO and 262 (50.6%) survived to discharge. Among 375 pediatric patients, 233 (62.1%) were successfully weaned from ECMO and 186 (49.6%) survived to discharge. Among 143 newborn patients, 90 (62.9%) successfully weaned from ECMO, 76 (53.1%) survived to discharge. ECMO was applied in veno-arterial (VA) mode to 501 (96.7%) patients, veno-venous (VV) mode to 14 (2.7%) patients, and VV-VA conversion mode to 3 (0.6%) patients. Sixty-nine patients required extracorporeal cardiopulmonary resuscitation (ECPR), including 20 newborn patients (29.0%) and 38 pediatric patients (71.0%), who were all with cardiovascular disease. Neonatal respiratory distress syndrome (26/61), persistent pulmonary hypertension of the newborn (PPHN) (12/61), and meconium aspiration syndrome (MAS) (11/61) are the most common pulmonary diseases in newborn patients; among whom, infants with PPHN had highest survival rate (10/12), followed by MAS (9/11). Among newborn patients with cardiovascular diseases, those who admitted were after surgery for congenital cardiac disease were the most common (54/82), while those with septic shock had the highest survival rate (2/3). In pediatric pulmonary diseases, acute respiratory distress syndrome was the most common (42/93), while plastic bronchitis was with the highest survival rate (4/4), followed by viral pneumonia (13/16). Among pediatric cardiovascular diseases, congenital cardiac defect was the most common (124/282), while fulminant myocarditis had the highest survival rate (54/77).@*Conclusion@#The application of ECMO as a rescue therapy for children with severe cardiopulmonary failure has dramatically developed in China mainland.
ABSTRACT
Objective To investigate the effects of glucocorticoid and blood purification on cellular immune function and prognosis in children with severe sepsis/septic shock. Methods Fifty-five pediatric patients with severe sepsis/septic shock admitted to PICU of Shandong Provincial Hospital between January 2015 and June 2017 were enrolled in the study and were divided into control group,hormone group and con-tinuous blood purification group according to treatment. PCIS,PICU stay,immune function,3\7\28-day mor-tality rate,the level of HLA-DR/CD14,TNF-α and IL-10 of pre-treatment,24 h and 72 h post-treatment were studied and compared among three groups. Results (1) Three-day (26. 7% vs. 20. 0% vs. 20. 0%) and 7-day mortality rates in blood purification group,hormone group,and control group were 4/15,4/20,4/20 and 5/15,5/20,5/20,respectively,which were the highest in blood purification group,but 28-day mortality rate(5/15 vs.7/20 vs.8/20)was the lowest in blood purification group. (2) PCIS,the expressions of HLA-DR/CD14,CD4 +,CD8 +and CD4 +/CD8 +increased in all groups while they increased significantly in blood purification group(P<0. 05). The levels of TNF-α and IL-10 in peripheral blood of children decreased gradually in each group,especially in blood purification group. Conclusion Comparing with hormone group, continuous blood purification therapy can remove inflammatory mediators more quickly and effectively,reduce cytokine level and improve cellular immune function in children with severe sepsis/septic shock,and reduce their 28-day mortality.
ABSTRACT
Convulsion is one of the most common pediatric emergencies.It can be caused by many factors,and the most common one is febrile convulsion.A severe or prolonged seizure can cause neurological damage,so it is necessary for timely and standardized treatment.The first step in emergency treatment is to keep the airway unobstructed,and control convulsion as soon as possible.The second step is to look for the cause of the disease,and to follow up the drug treatment for the cause of the disease.Children should be admitted to hospital for further diagnosis and treatment when necessary.
ABSTRACT
BACKGROUND:microRNA-17 is confirmed to play an important role in the development of pulmonary hypertension. Some research has shown that hypoxia-induced proliferation in human pulmonary artery smooth muscle celldepends on the induction of arginase II. There is no report about whether there is some interaction between microRNA-17 and arginase II in human pulmonary artery smooth muscle cells. OBJECTIVE:To investigate the possible interactions between microRNA-17 and arginase II in hypoxic human pulmonary artery smooth muscle cells. METHODS:Passage 4 human pulmonary artery smooth muscle cells were cultured in 21%O 2 and 5%CO 2 (normoxia) or 1%O 2 and 5%CO 2 (hypoxia), and then transfected with mimic or inhibitor of microRNA-17 or arginase II-smal interfering RNA. RNA, microRNA and protein were isolated separately. Expression of microRNA-17 and arginase II was detected with real-time quantitative PCR and western blot assay. RESULTS AND CONCLUSION:The level of microRNA-17 was significantly increased in cultured human pulmonary artery smooth muscle cells exposed to 1%O 2 hypoxia, as was arginase II mRNA and protein expression. Furthermore, inhibition of microRNA-17 expression decreased the mRNA and protein levels of arginase II in the human pulmonary artery smooth muscle cells under hypoxia. Conversely, over-expression of microRNA-17 increased the mRNA and protein levels of arginase II in the human pulmonary artery smooth muscle cells under normoxia and hypoxia. Knockdown of arginase II by siRNA abolished the hypoxia-induced up-regulation of microRNA-17 expression. These findings indicate that arginase II is a target gene of microRNA-17 and can regulate the expression of microRNA-17 in human pulmonary artery smooth muscle cells.
ABSTRACT
Objective To explore the changes and clinical value of serum insulin like growth factor-1 (IGF-1) and adiponectin in newborns with hypoxic ischemic encephalopathy (HIE). Methods Fifty-two HIE newborns were recruited in this study, including 15 severe, 20 moderate and 17 mild HIE newborns. Twenty healthy newborns were selected as controls. Serum levels of IGF-1 and adiponectin were detected 3-to-5 days (acute period) and 10-to-14 days (recovery period) after birth. Results Serum levels of IGF-1 and adiponectin in the acute period differed signiifcantly among groups of different severity (P<0.05). Serum levels of IGF-1 and adiponectin were decreased with the increase of HIE severity. The level of adiponectin in moderate and severe HIE was lower than that in mild HIE (P<0.05). In recovery period, the level of IGF-1 in severe HIE was lower than that in control (P<0.05). Serum levels of IGF-1 and adiponectin in the acute period was positivity correlated with those in umbilical cord blood of HIE newborns (r=0.531, r=0.611, P<0.01). Conclusions Decreased levels of IGF-l and adiponectin in HIE newborns are correlated with the pathological process of HIE, and can be regarded as indices for severity of HIE. IGF-l and adiponectin is of signiifcance in the clinical diagnosis and prognosis of HIE.
ABSTRACT
Objective To observe the complications in children after percutaneeus closure of atrial septal defect (ASD). Methods 192 children,who successfully received percutaneous closure of ASD in our hospital were enrolled in this study. Diameter of ASD was 8.0 ～ 33.0( 16.7± 8.0) mm, the diameter of occluder was 8.0 ～ 38.0 ( 18.9 ± 8.2) mm. The follow-up term ranges from 1 month to 4 years, with a mean of 19.0 ± 4.5 months. Standard 12-lead electrocardiography (ECG) and transthoracic echocardiography (TIE) were performed before closure, 24 including: minimal-moderate residual shunt in 3 patients ( 1.6% ), atrial-ventricle block (AVB) in 1 ( 0.5 % ), sinus There were 184 cases of single-hole ASD, with complication rate of 2.7% (5/184) , including the complication rate in diameter of siagle-hole ASD less than 10mm was 0% , that in ASD between 10 mm and 20 mm was 1.7% (2/119) ,that in ASD more than 20 mm was 5.0% (3/60) ,while there were 8 cases of two- and multi-hole ASD, clusion, including 3 cases of minimal-moderate residual shunt, 1 case of atrial-ventricle block, 1 case of sinus brady-cardia, and 1 case of device-micro-malplesition. 2 days to 2 weeks after procedure, 1 case developed pelade ( 1/192 ). completely recovered (57. 1% ), including 1 case of residul shunt, 1 case of atrial-ventricle block, sinus bradycardia and 1 case of pelade. 2 cases of minimal residual and 1 case of device-micro-malposition were not recov-ered. Conclusions Transeatheter closure of ASD is safe and effective with few complications, most of which disapp-eare completely during follow up term. Long-term follow-up is needed to evaluate the progress of some rare complica-tions.
