RESUMO
Objective:To summarize and analyze the clinical characteristics of different treatment in children with esophageal foreign bodies.Methods:This study collected 246 children with esophageal foreign bodies in our hospital from January 2016 to January 2020, which was divided into endoscopic group and operative group.The general and clinical data of children treated with different treatment were collected and statistical analyzed.Results:There were 222 children in endoscopic group and 24 children in operative group, respectively.The rate of surgery was 9.75%.There were no significant differences in gender and location of esophageal foreign bodies.However, the average age of operative group was(2.92±2.67) years, which significantly younger than that in endoscopic group(4.12±3.37)years( P=0.049). The residence time in operative group(median 29.10 h)was remarkable longer than that in operative group(median 11.80 h)( P<0.001). The proportion of sharpness(50.00%) and corrosive(45.83%) foreign bodies in operative group were more than those in endoscopic group[16.22% and 8.11%( P<0.001)]. Moreover, the occurrence rate of major complication in operative group was 83.33%, which was dramatically higher than that in endoscopic group(0.90%)( P<0.001). Conclusion:The younger and longer residence time of esophageal foreign bodies in children contribute to the rate of operative treatment.Additionally, the sharpness and corrosive foreign bodies increase the risk of surgery and serious complications.
RESUMO
Objective To observe the expression levels of IL-8,IL-4,TNF-α of neonatal mouse with systemic inflammatory response syndrome(SIRS) treated by different doses of dexamethasone.Methods A total of 50 neonatal mice were randomly divided into five groups:blank control group,saline control group and treatment group A,B,C.The saline control group and treatment groups were established into SIRS models,treatment group A:a single high-dose of dexamethasone (2 mg/kg),subcutaneous injection (SC) ; treatment group B:two doses of dexamethasone (1 mg/kg,q1 2 h,total 2 mg/kg,SC) ; treatment group C:four doses of dexamethasone (0.5 mg/kg,q 1 2 h,total 2 mg/kg,SC) ;saline control group:saline of the same volume (0.4 ml/kg,SC).All mice were detected IL-4,IL-8,TNF-α by ELISA 72 hours after animal models being completed.Results The levels of IL-4,IL-8,TNF-α in saline control group and treatment group A,B,C were higher than those in blank control group respectively (P ＜ 0.05,respectively).The levels of IL-4,IL-8,TNF-α in treatment group A,B,C were lower compared to those of saline control group respectively (P ＜ 0.05,respectively),levels of TNF-α,IL-8 in treatment group B and C were lower than those of treatment group A(P ＜ 0.05,respectively).There were no significant differences in the level of IL-4 among treatment group A,B,and C (P ＞ 0.05).Conclusion Dexamethasone could lower the expressions of pro-inflammatory cytokines IL-8,TNF-α and anti-inflammatory factor IL-8 of neonatal mouse with SIRS,and the effect of multiple low-doses of dexamethasone on SIRS is significantly better than a single high dose.
