ABSTRACT
AIM: To explore the correlation between neonatal retinal hemorrhage(RH)and changes in umbilical artery blood gas analysis.METHODS: A total of 312 full-term neonates born in our obstetrics department from January 2019 to December 2021 were selected as the study subjects. According to the RetCam III fundus examination results, 245 neonates who did not experience RH were included in the control group, while 67 cases with RH were found to be included in the RH group. In addition, neonates were grouped into I degree group(n=20), II degree group(n=29), and III degree group(n=18)based on the degree of RH. General clinical data and umbilical artery blood gas analysis indicators between the RH group and the control group were compared; the levels of umbilical artery blood gas analysis indicators in neonates with different degrees of RH, the relationship between pH and RH degree, and the influencing factors of neonatal RH were analyzed.RESULTS: There was no obvious difference in maternal age, average gestational week, fetal gender, parity, gestational diabetes, fetal birth weight, and amniotic fluid between the RH group and the control group(all P>0.05), while there were obvious differences in delivery methods, gestational hypertension, forceps assisted delivery, neonatal asphyxia, and umbilical cord around the neck(all P<0.05). The pH value, arterial blood sample partial pressure(PaO2)and base excess(BE)values of the RH group were obviously lower than those of the control group(all P<0.01), while the arterial carbon dioxide partial pressure(PaCO2)was obviously higher than that of the control group(P<0.01). There were obvious differences in umbilical artery blood gas analysis indicators among children with different degrees of RH(P<0.05), and with the increase of the degree of RH, pH value, PaO2 and BE gradually decreased(P<0.05), and PaCO2 gradually increased(P<0.05). There was a negative correlation between the degree of RH and the pH of umbilical artery blood gas analysis(rs=-0.593, P<0.05). The results of multivariate Logistic regression analysis showed that delivery method, gestational hypertension, forceps assisted delivery, neonatal asphyxia, umbilical cord entanglement, pH, PaO2, PaCO2, and BE were all influencing factors for the occurrence of neonatal RH.CONCLUSION: There is a close correlation between neonatal RH and changes in umbilical artery blood gas analysis, and umbilical artery blood gas analysis can be used for the diagnosis of neonatal RH, which can be used to guide clinical treatment.

ABSTRACT
OBJECTIVE@#To summarize clinical predictors and imaging characteristics of critically ill children infected with SARS-CoV-2 Omicron with neurological complications in Shenzhen during the peak of the first round of infections.@*METHODS@#The clinical data of 11 critically ill children with neurological complications infected with SARS-CoV-2 Omicron in Shenzhen Children's Hospital from December 12 to 31, 2022, were retrospectively collected and analyzed. Laboratory test results related to liver parenchymal injury, histiocytic injury, inflammation, and coagulation function were collected, and imaging characteristics including CT and/or magnetic resonance imaging (MRI) were analyzed. The differences in CT/MRI score, acute necrotizing encephalopathy severity scale (ANE-SS) score and total score (CT/MRI score + ANE-SS score) were compared between the two groups with different prognosis during hospitation.@*RESULTS@#Among 11 children, 7 were male and 4 were female. The age ranged from 10 months to 16 years. There were 5 cases of acute necrotizing encephalopathy (ANE) and 6 cases of acute fulminant cerebral edema (AFCE). During hospitalization, 3 patients survived and 8 patients died of multiple organ dysfunction syndrome (MODS), including 2 cases of ANE and 6 cases of AFCE. All cases had fever (> 38.5 centigrade), and 3 cases had ultra-high fever (> 41 centigrade). Within 48 hours of onset, all cases had disorders of consciousness and 9 cases had seizures. The 8 dead children had complications with multisystem involvement, including shock, respiratory failure, disseminated intravascular coagulation (DIC), liver failure, renal failure or myocardial damage, and the laboratory predictors related to hepatocellular injury [alanine aminotransferase (ALT), aspartate aminotransferase (AST)], histocyte injury [creatine kinase (CK), lactate dehydrogenase (LDH)], inflammation [procalcitonin (PCT), interleukin-6 (IL-6), serum ferritin (SF)], coagulation function (D-dimer) and blood glucose (Glu) increased in different quantities, of which PCT was specifically increased in 6 cases with AFCE, PLT was specifically decreased in 3 cases with AFCE, and ALT and LDH were significantly increased in 2 cases with ANE. Imaging analysis showed subarachnoid hemorrhage, basal ganglia and thalamus lesions in all 6 cases with AFCE, while thalamus lesions in all 5 cases with ANE. The ANE-SS score of 8 deceased children ranged from 2 to 7 (of which 6 cases were ≥ 5), and the ANE-SS score of 3 surviving children ranged from 0 to 2. Eight dead children had a CT/MRI score of 1-4 (of which 6 cases were 4), and 3 surviving children had a CT/MRI score of 1-2 (of which 2 cases were 1). The total score of 8 deceased children was 6-10 (of which 6 cases ≥ 8), and 3 surviving children was 1-4.@*CONCLUSIONS@#The neurological complications of critically ill children infected with SARS-CoV-2 Omicron in Shenzhen progressed rapidly to ANE and AFCE, with high mortality. High fever (> 40 centigrade), convulsion/disturbance of consciousness, and multiple organ failure were the most common symptoms in ANE and AFCE cases. PCT increased and PLT decreased specifically in AFCE cases. Poor prognosis (death) was more common in age < 4 years old, predictors of ALT, AST, CK, LDH, PCT, D-dimer, Glu, IL-6 increased significantly, PLT decreased significantly. The common imaging feature of ANE and AFCE is the involvement of dorsal thalamus, a new imaging sign of AFCE (subarachnoid hemorrhage) was found. The higher the ANE-SS score, CT/MRI score and total score, the greater the risk of death.

Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

ABSTRACT
Objective To investigate the clinical characteristics of invasive fungal infections(IFI) in PICU and analyze the risk factors for diagnosis and treatment earlier.Methods The clinical data of patients with IFI hospitalized in PICU from January 2013 to December 2017 were retrospectively studied.Results There were 179 cases of patients with positive fungal cultures,of which 49 cases were IFI.There were 23 males and 26 females,the mean age was (3.87 ± 2.42) years.A total of 47 cases had underlying diseases.In positive specimen,there were 36 cases of bronchoalveolar lavage fluid or sputum cultures,14 cases of blood cultures,7 cases of urinary cultures,3 cases of thoracic/ascites cultures,2 cases of bone marrow cultures,and 1 case of cerebrospinal fluid culture.There were 12 cases who had at least two sites infection at the same time.A total of 53 strains of fungal pathogens were cultivated,among which 45 cases were candida,5 cases were aspergillus,and 3 cases were penicillium marneffei,and 4 cases had two fungal infections.The presence of underlying diseases,blood transfusions,use of antibiotics/glucocorticoids/immunosuppressors,invasive procedures,and long hospital stays were risk factors (all P < 0.05).Drug susceptibility analysis showed that all strains were sensitive to antifungal drugs of amphotericin B/liposomes,azoles and echinocandins,except 1 case of Candida utilis,1 case of Saccharomyces cerevisiae and 1 case of Candida lusitaniae.There were 26 patients only treated with one antifungal drug and 23 had combined drugs.All patients had fever.Eleven patients developed multiple organ dysfunction syndrome and 6 died.Conclusion There are no specific clinical manifestations for children with IFI and with critical condition and high mortality.Candida is the most common fungal infection.The lung is the most common part of infection.The children of IFI with risk factors such as underlying diseases,blood transfusions,use of antibiotics/glucocorticoids/immunosuppressors,invasive procedures and long hospital stays,should be identified in combination with laboratory examination and use antifungal drugs rationally as early as possible.
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 discuss the influence of microRNA(miR)-155/miR-21 on toll-like receptor 4 (TLR4) in children with sepsis.Methods Fifty children with sepsis who were hospita-lized in Pediatric Intensive Care Unit,Shenzhen Children's Hospital,were enrolled in the study,and 15 healthy children at the same age were selected as healthy control group.Expression levels of TLR4 protein and human leukocyte antigen(HLA)-DR in CD14 + monocytes (MC) were detected by using flow cytometry,and sepsis patients were divided into 2 groups according to whether they exceeded the value of HLA-DR by 30% or not.Expression level of programmed cell death factor 4 (PDCDM) and inositol phosphatases 1 containing SH2 (SHIP1) were detected at the same time.MC were separated by CD14 + immune magnetic bead,and expression level of miR-155,miR-21 and tumor necrosis factor-α (TNF-α),interleukin-10 (IL-10) mRNA in CD14 + MC were detected by using real-time fluorescent quantitative PCR.Results Sepsis group consisted of 27 male and 23 female,and their ages were (2.34 ± 0.79) years old,among whom 9 patients died.There were 36 patients in the HLA-DR increase group and 14 patients in the HLA-DR decrease group.Expressions ofTLR4(2.33±0.90),miR-155[(7.19±3.75) ×10 3] and TNF-α[(21.98±14.15) ×10-2 pg/L] in CD14 + MC were higher in the HLA-DR increase group than those in the HLA-DR decrease group [1.24±0.60,(4.83 ±1.17) × 10-3,(14.18±5.45) ×10-2 μg/L] and healthy control group[1.57±0.55,(3.99 ± 1.29) × 10-3,(1.61 ± 0.84) × 10 2 pg/L],and the differences were statistically significant(F =11.943,7.583,18.538,all P <0.05),while the expressions of miR-21 (12.10 ±5.66),IL-10[(29.74 ± 12.55) × 10-4 μg/L] in CD14 + MC were lower in the HLA-DR increase group than those in the HLA-DR decrease group[4.68 ± 2.07,(12.50 ± 5.73) × 10-4 μg/L] and healthy control group [2.39 ± 0.86,(2.04 ± 0.92) × 10-4 μg/L],and the differences were statistically significant(F =41.673,54.991,all P < 0.05).The levels of SH1P1 and PDCD4 decreased in sepsis compared with healthy control group[0.70 ±0.36)vs.(1.59 ±0.48);(1.55 ±0.56) vs.(3.01 ±0.70)],and the differences were statistically significant (t =7.682,8.339,all P < 0.05),but SHIP1 decreased more significantly in the HLA-DR increase group than that in the HLA-DR decrease group [(0.60 ± 0.34) vs.(0.97 ± 0.26)],and the difference was statistically significant (F =39.214,P < 0.05).PDCD4 decreased more significantly in the HLA-DR decrease group than that in the HLA-DR increase group (0.94 ±0.19 vs.1.79 ±0.47),the difference was statistically significant(F =65.367,P < 0.05).Conclusions Regulation imbalance of miR-155/miR-21 may be one of the reasons for abnormal expression of TLR4 in children with sepsis,and it plays a role in enlarged or inhibited expression of TLR4 in the sepsis process which results in different immune status in sepsis patients.
ABSTRACT
Objective To analyze the clinical characteristics of Kawasaki disease shock syndrome ( KDSS) and to improve the diagnosis,treatment and prognosis of patients. Methods A total of 924 cases of Kawasaki disease ( KD) hospitalized from January 2013 to April 2017 in our hospital were retrospectively an-alyzed,including 16 children with KDSS. And 30 patients with KD were randomly selected as the control group. The clinical characteristics,laboratory examination and treatment of the two groups were compared and analyzed. Results There were 9 males and 7 females in KDSS group,and average age was (3. 95 ± 2. 56) years. The average time to happen shock was (4. 31 ± 0. 79) days. There were no significant differences in gender,age and duration of fever between KDSS group and KD group respectively ( P >0. 05 ) . KDSS patients were more likely to develop abdominal pain, hepatic injury ( including elevated transaminase and jaundice),proteinuria,peritoneal effusion,pneumonia,coronary aneurysm,IVIG resistance and longer hospi-talization (P<0. 05). WBC[(28. 42 ± 10. 46) × 109/L vs. (20. 34 ± 7. 57) × 109/L],the neutrophils [(89.86 ± 7.00)% vs. (73.14 ± 13.91)%],hsCRP (mg/L) [181.95(141.58,218.00) vs.94.65 (55. 33,109. 50)],PCT(ng/ml)[9. 68 (4. 85,12. 07) vs. 0. 09 (0. 04,0. 37)] and serum ferritin (ng/ml) [(388. 12 ± 241. 75) vs. (169. 86 ± 95. 14)] in the KDSS group was significantly higher than those in KD group (P<0. 05). There were no differences in ESR(mm/h) [(75. 71 ± 25. 25) vs. (79. 87 ± 22. 76)], fibrinogen (g/L) [(6. 17 ± 1. 45) vs. (6. 03 ± 1. 47)] between two groups (P>0. 05). The levels of plate-let count[ (655. 50 ± 226. 98) × 109/L vs. (549. 93 ± 119. 15) × 109/L],the albumin (g/L) [(22. 54 ±5.13)vs.(33.32±3.18)],serumsodium(mmol/L)[(130.47±2.79)vs.(134.77±2.81)]andserumpotassi-um (mmol/L) [(4. 59 ± 0. 74) vs. (4. 04 ± 0. 43)] and ejection fraction [(60. 16 ± 6. 18)% vs. (64. 81 ± 3. 71)%] in KDSS group were lower than those in KD group (P<0. 05). During the course of treatment,14 patients were accepted fluid resuscitation and the average volume of fluid was (27. 19 ± 19. 58) ml/kg. Ten patients used vasoactive drugs. Six patients were treated with hormone ( methylprednisolone ) . All patients were discharged from hospital. Conclusion KDSS is a serious form of KD,the indicators of inflammatory response increased more obviously. Organ damage occurs more frequently,and often accompanies abdominal pain. Anti-shock treatment often requires fluid resuscitation and use of vasoactive drugs.
ABSTRACT
Objective To explore the clinical features of nephrotic syndrome combined with H1N1 influenza. Methods The clinical manifestations, laboratory and image examinations, treatment, and prognosis of nephrotic syndrome combined H1N1 influenza were retrospectively analyzed in 15 children with. Results All of 15 children with nephrotic syndrome met the diagnostic criteria of H1N1 influenza. The median age of all children was 4-year-8-month old (2-year-2-month to 6-year-9-month). All children were treated with hormone alone or combined with other immunosuppressive drugs. Three cases were severe and another 5 cases were critically ill. Four cases were complicated with recurrence of nephrotic syndrome, 2 of which suffered from acute renal insufficiency. All children were given oseltamivir as antiviral treatment at admission. Four cases took oseltamivir within 48 hours of onset and showed mild symptoms. Fourteen children with H1N1I influenza were cured, their urinary proteins were significantly decreased or converted to negative, and the median hospital stay was 8 days (1 to 25 days). One child died of acute necrotizing encephalopathy and brain herniation. Conclusions Children with nephrotic syndrome are susceptible to severe or critical H1N1 influenza infections. During the epidemic of H1N1 influenza, the clinical preventive measures should be taken in children with nephrotic syndrome.

ABSTRACT
Objective To discuss the expression level of serum procalcitonin( PCT) and clinical val-ue in acute viral diarrhea patients. Methods A total of 186 patients with acute viral diarrhea treated in our hospital from September 2013 to September 2015 were retrospectively reviewed. One hundred and seven were male and 79 were female,of which 171 cases were infected by rotavirus and 15 cases infected by norovirus. The average age was ( 1. 29 ± 0. 89 ) years old. All patients′ blood and stool cultures were negative. The patients were divided into three groups according to the degree of dehydration and whether complicated with multiple organ dysfunction or not:severe group( complicated with severe dehydration,shock or multiple organ dysfunction,n=33),mild-moderate dehydration group(n=68) and no dehydration group(n=85). Thirty-five healthy children with the same age were enrolled as the control group. Serum PCT levels,high sensitivity CRP(hs CRP) and blood routine were detected. Results The serum PCT levels increased in 73 patients with acute viral diarrhea,8 cases>100 ng/ml,21 cases 5 to 100 ng/ml and 44 cases 0. 5 to 5. 0 ng/ml. PCT( ng/ml)[0. 36(0. 14,1. 67),hsCRP(mg/L)[3. 50(0. 70,14. 83)] and WBC( × 109/L)[9. 06(6. 79,12. 50)] levels increased in the diarrhea patients compared with those in the healthy group[0. 09(0. 05,0. 13);1. 00 (0.40,2.50);6.90(5.90,8.20)](all P 0. 05 ) . Conclusion PCT can increase in pediatric patients with acute viral diarrhea,especially in those with severe dehydration,shock and organ dysfunction. Continued high levels of PCT indicates critical condition and has poor prognosis. PCT can be used as a good indicator to evaluate the severity of disease and the prognosis.
ABSTRACT
<p><b>OBJECTIVE</b>Sepsis is the major cause of death in pediatric intensive care unit (PICU). The clinical manifestations of early sepsis is very similar to systemic inflammatory response syndrome (SIRS) caused by non-infectious reason. This study aimed to investigate the expression of miRNA and inflammatory cytokines in plasma in pediatric sepsis patients and its clinical significance.</p><p><b>METHOD</b>Forty children with sepsis seen in Shenzhen children's hospital PICU from April 2012 to March 2013 were enrolled in this study, the median age was 0.75 (0.52, 1.90) years; 27 were males and 13 females, of whom 16 had severe sepsis. We selected 20 postsurgical patients with SIRS and 15 healthy children as a control group. The expression levels of plasma miR-21, miR-125b, miR-132, miR-146a, miR-155 and miR-223 were detected by real-time quantitative PCR (qRT-PCR). The predictive value of miRNA, PCT and CRP for sepsis were evaluated by Receiver operating characteristic curve (ROC). TNF-α and IL-10 levels in plasma detected by Cytometric Beads Array (CBA). Quantitative data of normal distribution was compared with ANOVA among the three groups and LSD-t test between two groups. To non-normal distribution of data, multiple comparisons among three groups were conducted by Kruskal-Wallis H test and differences between two groups were assessed by Mann-Whitney U test for post hoc analysis.</p><p><b>RESULT</b>There were no significant differences between the age and gender of each group. Expression of miR-21, miR-125b, miR-132 and miR-155 in plasma had no significant difference in each group (all P > 0.05). MiR-146a and miR-223 levels in sepsis were upregulated compared with SIRS group and control group [(5.7 ± 3.5)×10(-5) vs. (2.4 ± 1.6)×10(-5) and (2.6 ± 1.2)×10(-5), (12.5 ± 7.7)×10(-4) vs. (8.3 ± 3.4)×10(-4) and (5.3 ± 2.2)×10(-4), all P < 0.01], expression levels of miR-223 in SIRS increased as compared to control group (P < 0.01). MiR-146a levels in severe sepsis were higher than those of the general sepsis [ (7.1 ± 3.3)×10(-5) vs. (4.6 ± 2.6)×10(-5), P < 0.01]. CRP and PCT levels are all higher in sepsis and SIRS groups than control group (all P < 0.01). The area under ROC curve (AUC) of miR-146a, miR-223, PCT and CRP to predict sepsis were 0.815 (95%CI: 0.708-0.922), 0.678(95%CI: 0.537-0.818), 0.706 (95%CI: 0.571-0.842) and 0.588 (95%CI: 0.427-0.748). Expression levels of IL-10 and IL-10/TNF-α in sepsis were upregulated compared with and SIRS group and the control group (all P < 0.01). There was a positive correlation between miR-146a, miR-223 and IL-10 and IL-10/TNF-α (r = 0.545, 0.305, 0.562, 0.373, all P < 0.01).</p><p><b>CONCLUSION</b>The expression levels of miR-146a and miR-223 in plasma in pediatric patients with sepsis was significantly upregulated, and had a positive correlation with IL-10 and IL-10/TNF-α, which may be used as early diagnostic markers and can reflect the severity of condition to a certain degree.</p>

ABSTRACT
Objective To evaluate the clinical effect of breast implant on congenital mammary dysplasia with mild pigeon chest deformity. Methods From January 2003 to July 2009,10 cases of female mammary dysplasia (between 20 to 31 years of age) underwent breast implant surgery. Subpectoral placement and transaxillary incision were selected. The surgeon marked the range of the operation on the skin, made a 3-4 cm incision in the armpit, separated the tissue until the pectoral lateral margin, cut the pecto-ralis fascia and bluntly created a suitable pocket under the pectoralis major for the implant. After the implant was placed in the pocket, the incision was closed. Results Ten cases of breast implant surgery did not pose the complications of local skin necrosis, infection, implant shift, heart and lungs dysfunction after one year follow-up. The appearance of anterior chest wall deformity was markedly improved. Conclusions The application of breast implant surgery in the treatment of congenital mammary dysplasia with mild pigeon chest deformity should be promoted, because of the double surgical effect of easy performing, minimal surgical damage, perfect breast shape and concealed deformity.

Objective To investigate the role of fluid therapy in treatment of septic shock in children.Methods A total of 48 pediatric patients with septic shock were enrolled.Twenty-seven patients were treated with volume expansion and 21 patients were treated with fluid resuscitation.There were no differences in use of antibiotics,inotropic and vasoactive agent in two groups.The time needed for haemodynamic stability,occurrence of pulmonary edema.length of PICU stay,and mortality were compared between two groups.Results Compared with volume expansion group,the time needed for haemodynamic stability significantly decreased in fluid resuscitation group ((216.10± 168.13) minutes vs (121.63 ± 75.59) minutes) (P 0.05) .Compared with volume expansion group,length of PICU stay significantly decreased in fluid resuscitation group ((6.188 ±3.250) days vs (3.944±2.711) days,P < 0.05).Compared with volume expansion group,mortality significantly decreased in fluid resuscitation group (40.7% vs 14.3%,P < 0.05) . Conclusions Rapid fluid resuscitation was associated with early reach of haemodynamic stability,short stay in PICU,improved survival rate and no increase in the risk of complication in pediatric patient with septic shock.
ABSTRACT
Carefully evaluation of cardiovascular function in children with septic shock is the basis of appropriate therapy.Clinical methods of cardiovascular function evaluation include clinical manifestation,hemodynamic momtoring and laboratory test of tissue oxygenation.Evaluation of cardiovascular function should combine all results from different methods and should be dynamically monitored with the development of septic shock.
ABSTRACT
Objective To further explore the pathogenesis of disturbed adaptive immune response in infants with sepsis. Methods Forty-eight infants with sepsis and 26 age-matched healthy infants were enrolled in this study. The HLA-DR expression of CD14~+ monocyte, the proportion of CD4~+ CD25~+ Foxp3~(high) Tr cells and the proportion of Thl7 cells were measured by flow cytometry. Cytokines (IL-1β, IL-6, TNF-α, IL-10, TGF-β and IL-17A) were measured by ELISA. Real-time PCR were used to evaluate the mRNA levels of Foxp3, ROR-γt in CD4-positive cells and IL-17A. Forty-eight infants with sepsis were divided into two groups according to HLA-DR expression of CD14~+ monocyte: DR-H group ( > 30% ) and DR-L group ( < 30% ). Results The ratio of IL-10/TNF-α in DR-L group was higher than that in healthy control or DR-H group(P <0.05). The proportion of CD4~+ CD25~+ Foxp3~(high) Tr cells and mRNA expression of transcription factor Foxp3 in DR-L group was found to be significantly higher than that in healthy control or DR-H group(P<0.05). The proportion of Thl7 cells, Serum concentration of IL-17A, the mRNA expression of IL-17A and transcription factor ROR-γt were significantly increased in DR-H group and DR-L group (P < 0.05) , while there is no significant difference between DR-H and DR-L group( P >0.05). Serum levels of Th17-inducing cytokine such as IL-1β, IL-6 were significantly elevated in DR-H group and DR-L group (P<0.05), while there is no significant difference between DR-H and DR-L group( P>0.05). Serum level of CD4~+ CD25~+ Foxp3~(high) Tr-inducing cytokine TGF-p in DR-L group was higher than that in DR-H or healthy control group(P<0. 05). Conclusion Over-activation of Th17 cells may be one of the factors causing aberrant increase of pro-inflammatory cytokine/chemotatic factor in infant with sepsis. The imbalance of CD4~+ CD25~+ Foxp3~(high) Tr cells/Th17 cells may be contributed to the pathogenic mechanism of mixed antagonist response syndrome ( MARS) in infant with sepsis. The changes of cytokine environment in infants with sepsis may be one of the factors causing the imbalance of CD4~+ CD25~+ Foxp3~(high) Tr cells/Th17 cells.
