RESUMO
Objective:Based on 108, 591 cases of pediatric emergency visits in a Level Ⅲ Grade A women and children′s hospital in Guangzhou area, we analyze the disease spectrum and epidemiological characteristics, and summarize the characteristics of patient flow changes.These investigations will provide an basis for scientific decision-making for manpower and material resource management of pediatric emergency and hospital workflow design.Methods:The children admitted to the Pediatric Emergency Department of the Zhujiang New Town District of Guangzhou Women and Children′s Medical Center from October 2016 to September 2018, including night emergency and inpatient observations, were analyzed according to the admission date, admission time, gender, age, initial diagnosis and etc.Results:There were more boys than girls in the emergency department, whose ratio was 1.46∶1 (64 480∶44 111 cases). The age of children ranged from 0 to 17 years old, with a median of 11 (23, 48) months.The age distribution was mainly under 5 years old, accounting for 84.14% (91 336/108 591). During the whole year, the number of children in July was the most, accounting for 10.53% (11 433/108 591), and the children in February were the least, accounting for 6.04% (6 555/108 591). The highest visit time of the whole day was 22-23 pm, accounting for 18.83% (20 443/108 591). The most of the diagnosis was respiratory disease, accounting for 53.83% (66 522/123 576). A total of 1 057 critically ill children were received, accounting for 0.97% (1 057/108 591). A total of 911 accidental injuries were received, accounting for 0.84% (911/108 591). Acute upper respiratory tract infection was the most among all diagnoses, accounting for 34.47% (42 541/123 576).Conclusion:Children in the pediatric emergency department of Guangzhou Women and Children′s Medical Center are mainly under 5 years old, and the number of children is the most in July of the year.The main disease is respiratory diseases.Medical staff can be trained according to the actual situation, and the disease spectrum can be updated in time to provide convenience for emergency rescue and improve service level.
RESUMO
Objective To investigate the optimal initial concentration of microRNA22 agomir in epilepsy model induced by lithium chloride-pilocarpine after single injection of lateral ventricle.Methods 36 rats with acute temporal lobe epilepsy were randomly divided into 6 groups:the control group and the other five groups were the experimental group.All epilepsy rats were selected for right lateral ventricle injection.The control group was given negative control reagent,while the experimental group were given 0.1 mmol/L,2.5 mmol/L,5 mmol/L,10 mmol/L,20 mmol/L different concentrations of miRNA22agomir reagent.6 rats in each group were randomly selected for acute phase experiment after 3 days of administration.The expression of P2X7 in hippocampus of epilepsy rats was determined by Western blot and quantitative real-time polymerase chain reaction (qRT-PCR).Results Compared with control group,the protein and mRNA expression of P2X7 reduced in all of the model group.The protein and mRNA expression level of P2X7 protein in hippocampus of rats injected with 2.5 mmol/L,5 mmol/L and 10 mmol/L in each experimental group were significantly lower than that in the other two groups (P ＜ 0.05).Moreover,the protein and mRNA expression level of P2X7 were the lowest at 2.5 mmol/L injection and 10 mmol/L,and there was no significant difference between the two groups (P ＞ 0.05).Conclusions The optimal onset concentration for unilateral lateral ventricle injection miRNA22 agomir treatment of temporal lobe epilepsy is 2.5 mmol/L.
RESUMO
Objective To observe the therapeutic efficacy and safety of acupuncture and epidural anesthesia during full-term labor. Method A total of 199 eligible subjects experiencing natural labor were randomized into four groups. The acupuncture group was intervened by acupuncture at acupoints; the epidural group was given epidural anesthesia;the combined analgesia group was given acupuncture at acupoints plus epidural anesthesia; the control group was not given any interventions for analgesia. The Visual Analogue Scale (VAS) was adopted to record and compare labor pain (cervix dilation 3 cm at 0 min, 30 min, and 60 min, and at full cervix dilation); meanwhile, the active period of the first stage of labor, cervix dilation speed, the second stage of labor, Caesarean section (C-section) rate, instrumental delivery rate, Apgar score, and post-labor bleeding amount (2 h) were also recorded. The contents of blood β-endorphin (β-EP) and 5-hydroxytryptamine (5-HT) were monitored during the first stage of labor. Result Compared with the control group, the VAS scores dropped in the other three groups, and the decreases were similar in the epidural group and combined analgesia group, while the decrease in the acupuncture group was the least significant. Regarding the labor-related indexes, the cervix dilation speed was higher in the acupuncture group than in the control group(P0.05). There were no significant between-group differencesin comparing the post-labor bleeding amount and Apgar score of the new-born babies(P>0.05), but compared with the epidural group, there was no use of assisted delivery. The content of blood β-EP during the first stage of labor increased in the acupuncture group and combined analgesic group(P0.05). Conclusion Acupuncture analgesia can reduce labor pain and shorten labor duration without affecting the second stage of labor and security-related indexes.

RESUMO
Objective To explore the variation of insulin like growth factor-I (IGF-I) and glucose and correlation in children with sepsis. Methods Forty-two children with sepsis in pediatric intense care unit were enrolled from January 2009 to January 2010. In the morning (2nd morning) after admission, the blood glucose, serum IGF-I, cortisol, insulin, IL-6, and IGF-binding protein-I (IGFBP-1) were detected. In the 3rd and 5th morning, the serum IGF-1 was detected again. According to the blood glucose level of the 2nd morning, the children with sepsis were divided into hyperglycemia group and normal group. Meanwhile, 60 healthy children were served as control group. The data had been compared among three groups. Results In the 2nd morning, the levels of blood glucose, serum IGF-I, cortisol, insulin, and IL-6 were signiifcantly different among three groups (all P0.05). Compared with control group, the sepsis children with hyperglycemia and with normal blood glucose all had signiifcantly higher serum levels of cortisol and IL-6, and signiifcantly lower serum level of IGF-I. In the 2nd, 3rd, and 5th morning, the serum levels of IGF-1 were not signiifcantly changed with time in sepsis children with hyperglycemia and with normal blood glucose (all P>0.05). Meanwhile, there were no signiifcant differ-ences in the serum levels of IGF-1 between sepsis children with hyperglycemia and with normal blood glucose in the 2nd, 3rd, and 5th morning (all P>0.05). In children with sepsis, the blood glucose and serum IGF-1 was not correlated in the next morning (r=0.152, P=0.267). Conclusions The serum level of IGF-I decreased but maintain stable in children with sepsis. The change of blood glucose may be not related with IGF-I.
RESUMO
Objective To investigate the relationship among serum levels of suppressors of cytokine signaling-3(SOCS-3),insulin-like growth factor binding protein-1(IGFBP-1) and hyperglycemia in critically ill children. Methods The 64 critically ill children who suffered from sepsis,after surgical repair of congenital heart dis-ease by extracorporeal circulation, and after surgery of severe traumatic from January 2009 to January 2012 in Depart-ment of Pediatric Intensive Care Unit( PICU) of Guangzhou Women and Children′s Medical Center were selected as the research object. According to the blood glucose levels on admission, the 64 children were divided into the normal glu-cose group and the hyperglycemia group. The 15 cases of healthy children in the same period in Guangzhou Women and Children′s Medical Center were selected as the healthy control group. The levels of blood glucose,insulin,SOCS-3,IG-FBP-1 and insulin resistance index( HOMA-IR) were measured and compared among groups when they were on ad-mission. Results (1) The blood glucose of the hyperglycemia group was significantly higher than those in the normal glucose group and the healthy control group[(9. 83±2. 48) mmol/L vs (4. 82±0. 76) mmol/L,(4. 49±0. 81) mmol/L] (P0. 05). (4) The blood glucose was positively correlated with the insulin and HOMA-IR(r=0. 455,0. 773,P0. 05). Con-clusions In the critically ill children,hyperglycemia was related to the insulin resistance which can not be evaluated through changes in serum levels of SOCS-3 and IGFBP-1. In addition,it cannot be excluded that the critically ill chil-dren may have insulin resistance and pancreaticβ-cell dysfunction simultaneously.
RESUMO
Objective To investigate the variation of interleukin-6 ( IL-6 ) , vascular endothelial growth factor(VEGF),E-selectin and intercellular adhesion molecule-1(ICAM-1)in children with sepsis and the clinical significance. Methods This was a prospective and control study. Thirty-two children diagnosed as sepsis in PICU from December 2008 to December 2009 served as the sepsis group. According to whether there was a shock, sepsis group were divided into shock subgroup and no shock subgroup. Fifteen healthy children served as control group. The serum levels of IL-6,VEGF,E-selectin and ICAM-1 were detected with enzyme linked immunosorbent assay. Results The serum level of IL-6 was 65. 00(30. 49~237. 14) ng/L in shock subgroup and 48. 68(30. 25~75. 00) ng/L in no shock subgroup,which were significantly higher than that in control group[0. 80(0. 60 ~1. 00) ng/L](P<0. 05). There was no significant difference between shock subgroup and no shock subgroup. The serum levels of VEGF and E-selectin showed no significant differences among the three groups. The serum level of ICAM-1 was 998. 72(666. 93~1 526. 44) ng/ml in shock subgroup,and 925. 71(683. 53~1 225. 12) ng/ml in no shok subgroup,which were significantly high-er than that in control group[660. 59(525. 48~685. 47) ng/ml]. Compared with those who survived in sep-sis group,the serum levels of VEGF and E-selectin in the died children with sepsis showed no significant difference,but IL-6 and ICAM-1 significantly increased(P<0. 05). Conclusion IL-6 and ICAM-1 increase greatly and accentuate inflammation in septic patients,the changes of which may help to determine the prog-nosis of sepsis.
RESUMO
Objective Through death analysis of critically ill children with interhospital transportation,to explore the cause of death and its influencing factors.Methods We collected the data of death cases within 24 hours who were one-way transported from primary hospital to the emergency department of Guangzhou Women and Children's Medical Center between July 2012 and May 2014.We analyzed the diseases type,physiopathologic status,and the treating measures in the process of transportation.Results There were total 1 122 cases,34 children died,the mortality was 3.0％,7 cases died before admission,27 cases died within 24 hours after admission.The first three types of diseases were respiratory system diseases(8/34,23.5％),nervous system diseases (7/34,20.6％) and accidental injury (6/34,17.6％).The physiopathologic status were analyzed according to physiological status and laboratory data at admission.Most of the children had a variety of physiopathologic status.Electrolyte disturbances were found in 22 cases(81.5 ％),metabolic acidosis and respiratory failure in 19 cases (70.4％).Most cases had intravenous channel (33/34,97 ％),intravenous infusion (32/34,94.1％)and electrocardiogram monitoring (30/34,88.2％),none of the cases received vasoactive agents in transportation.Conclusion Insufficient disease evaluation before the transportation of critically ill children,inadequate monitoring and treating measures on the way are important factors causing the death of children.
RESUMO
Abdominal aortoenteric fistula (AAEF) is a rare but life-threatening complication of abdominal aortic aneurysms, and is also an uncommon cause of gastrointestinal hemorrhage. We report a case of primary abdominal aortoduodenal fistula in a 74-year-old male patient, whose main clinical manifestations were abdominal pain, hematochezia, and hematemesis. Colonoscopy, abdominal enhanced computed tomography (CT) and three-dimensional reconstruction angiography confirmed the diagnosis. The patient recovered well after emergent surgical management.

Objective To explore the variation and clinical significance of growth hormone(GH) and insulin like growth factor-Ⅰ(IGF-Ⅰ) in children with critical disease.Methods One hundred and twenty-two cases were recruited into the study,among which 42 cases were sepsis in paediatric intensive care unit (sepsis group),20 cases had finished the cardiopulmonary bypass surgery without infection (surgery group).Sixty healthy children served as control group.Serum levels of GH and IGF-Ⅰ were deteced with immunochemiluminometric assay.Results The serum levels of GH were (6.71 ± 6.62) ng/ml in sepsis group,(8.86 ±8.06) ng/ml in surgery group,(3.87 ± 3.31) ng/ml in control group.Compared with the control group,the serum levels of GH in sepsis group and surgery group were increased significantly (P ＜ 0.05).There was no significant difference between sepsis group and surgery group.The serum IGF-Ⅰ levels were (63.72 ±54.17) ng/ml in sepsis group,(119.06 ± 102.12) ng/ml in surgery group and(154.22 ± 107.10) ng/ml in control group separately.The serum IGF-Ⅰ level of sepsis group was significantly decreased compared to the other two groups (P ＜ 0.05).There was no significant difference between surgery group and control group (P ＞0.05).In sepsis group,compared with those who died,the GH of the survival showed no significant difference,IGF-Ⅰ was significantly increased.(P ＜ 0.05).Conclusion GH playes a positive effect in patients with critical disease.IGF-Ⅰ decreases greatly in patients with serious infection.It suggests that IGF-Ⅰ could be a sensitive marker for reflecting whether there is serious infection.The sharply decreasing of IGF-Ⅰ may predict a bad outcome.
RESUMO
Objective To observe the correlation between the C-myc expression and pathologic lesions of kidney to explore the role of C-myc re-expression in children's primary nephrotic syndrome(CPNS). Methods The C-myc expression of renal tissue in 30 cases of CPNS was detected using immunohistochemical method, and the correlation between C-myc expression and renal pathological lesions was analyzed. Results There were various degrees of C-myc positive staining in the renal tissue of all patients with CPNS, while no C-myc positive expression in the renal tissue of control group. C-myc expression was mainly located in podocytes and less in endothelial cells of glomeruli. There was high level of C-myc expression in nephric tubules, especially in proximate tubules. There was no C-myc expression in the Henle's loop,tubulous matrix and vessel areas. There was no obvious difference in C-myc expression level in the podocytes and proximate tubules among the different pathological types of CPNS. The level of focal segmental glomerulosclerosis(FSGS) in proximate tubules obviously reduced compared with mesangil proliferative glomerulonephritis(MsPGN) and minimal change disease(MCD)(P
RESUMO
Objective To study the effect of dexamethasone on KGF expression in lungs of neonatal rats after hyperoxic exposure. Methods A randomized controlled study was designed in 48 Sprague-Dawley neonatal rats of 3 days old and divided into hyperoxia group, hyperoxia + dexamethasone and control groups for 7days. Histologic examination of the lung tissues were studied and radical alveoli count (RAC) were determined after HE staining. KGF expression was detected by immunohistochemistry. Results (1)The lungs of the rats in the hyperoxia group showed thinner walls of alveoli, simple alveolar structure, fewer and larger alveoli, expanded and shrinked alveoli. While those rats in the dexamethasone group showed more severe changes and some destroyed septa and walls of alveoli which lead to structure turbulence of the pulmonary tissue. The RAC in the hyperoxia and dexamethasone group was siginificanly lower than that in the control group (9.50?1.05, 10.03?3.26 vs 13.00?1.79, P
RESUMO
Objective To investigate the characteristics of stem cells marked with bromode oxyuridine (Brdu) and telomerase reverse transcriptase (TERT) in lung tissue, as well as its effects on pulmonary development and injury-repair. Methods A model of hyperoxia in neonatal rats was established by exposed to 95% O2 for 7 days. Before executing rats, Brdu was injected peritoneally, then Brdu and TERT positive cells were detected by immunohistochemistry. Results (1)The positive staining cells of Brdu with large nuclear located in septa and submucose of series bronchia, scattering in epithelium of bronchia, and the number of positive cells were less. The positive staining cells of TERT located in the septa and alveolar walls of peripulmonary tissue and the number of which was less than that of Brdu. (2)The positive cells of SPC located in septa and alveolar walls. Staining with Brdu and TERT, small number of positive cells was observed. (3) In hyperoxia and normal oxygen group, integral of expression of Brdu, TRET and SPC had no differences. But integral of expression of Brdu in whatever hyperoxia (1. 61?0. 83) or normal oxygen group (1. 43?0. 85) were higher than TRET and SPC (P
RESUMO
Objective To analyze the effect of circulatory failure on ventilation therapy of respiratory failure after resuscitation in neonates with severe asphyxia. Methods Three hundred and eighty-two neonates with mechanical ventilation following severe asphyxia were retrospectively analyzed. Two groups were divided according to the efficacy of mechanical ventilation: effective and noneffective. Results The non-effective rate was 24.1% at 1 hour after ventilation (19.4% in full term babies,34.5% in preterm babies). The degree of asphyxia in noneffective group was significantly more severe than the effective group. The incidence of persistent pulmonary hypertension of the newborns(PPHN),exsanguine shock,cardiogenic shock,DIC and cardiac failure was 84.3%、51.0%、80 4%、49.0% and 54.9% respectively in term babies,while the incidence of exsanguine shock,cardiogenic shock,DIC and cardiac failure was 65.9%、68.3%、75.0% and 58.5% respectively in preterms babies. All of them were significantly higher than the effective group. After treatment of the circulation problems,the blood gas turned to normal in 94.1% term babies and 92.7% of preterms. No difference was shown in the recovery rate in both groups. Conclusion The circulatory failure is a main cause of non-effective mechanical ventilation in asphyxia neonates. To correct the pathophysiologic changes of the circulation in time can effectively improve the prognosis.
