Objective To study the clinical features of neonates with enteroviral infection.Method We collected all neonates with enteroviral infection confirmed pathologically in the Department of Neonatology in the Children's Hospital of Fudan University from March 2009 to July 2016 retrospectively.The clinical data of the patients (clinical manifestation,first laboratory examinations,imaging findings,treatment procedures and outcomes) were retrieved to summarize the clinical features of neonatal enterovirus infection and to analyze the factors affecting the prognosis of neonatal enterovirus infection.Result A total of 81 neonates with enterovirus infection were included in the study.Among them,55 were full-term infants and 26 were premature infants,and the birth weight was (3 029±728)g.The median age of hospital admission was 5 (1,16) d,and multiple systemic manifestations were common in the course of the disease.Among them,19.8％(16/81)died.The factors for death are preterm birth,decreased hemoglobin,platelet count or serum albumin levels,abnormal coagulation,elevated blood lactate levels and acidosis.A scoring system was established based on high-risk factors.A score of ≥ 4 could reliably predict adverse outcomes,with a specificity of 92.3％ and a sensitivity of 93.8％.Conclusion Enteroviral infection in neonates can be highlt critical multiple system involvement.Neonates enterovirus infections with high risk factors(premature delivery,hemoglobin/ platelet/ albumin hypoplasia,coagulation dysfunction,lactic acid increase and acidosis) had higher mortality rate.There is a need to identify these neonates for intensive care and better treatment is warranted to improve the prognosis of these patients early.

Objective:To construct a classification management model of medical equipment in public hospitals based on association rules algorithm,and to analyze its application effect in hospital equipment management.Methods:Equipment classification management was performed based on Apriori algorithm(association rule analysis)and K-means algorithm(equipment abnormal information mining)in the association rules algorithm,the classification management model of medical equipment in public hospitals was constructed to mine the abnormal characteristics of equipment status.A total of 244 medical devices in clinical use in Beijing Huilongguan Hospital from 2022 to 2023 were selected.According to the application of the classification management model of medical equipment in public hospitals based on the association rule algorithm,the equipment use period from January to December 2022 was set before the application of the association rule algorithm model,and the equipment use period from January to December 2023 was set to the time after the application of the association rule algorithm model.The scores of equipment classification management,the failure rate of different types of equipment and equipment efficiency score before and after the application of association rule algorithm model were compared.Results:After the application of association rule algorithm model,the average scores of warehousing management,use management,maintenance management and scrap management were(89.65±4.65)points,(90.25±4.36)points,(87.69±3.12)points and(90.36±3.39)points,respectively,which were higher than before the application,the difference was statistically significant(t=17.866,14.671,18.128,19.479,P<0.05).After the application of association rule algorithm model,the number of medical image diagnostic and auxiliary equipment,health monitoring equipment,rehabilitation equipment and intervention and treatment equipment that failed was 2,3,2,and 3,and the failure rates were 3.33%,4.69%,2.86%and 6.00%,respectively,which were lower than those before the application,the difference was statistically significant(x2=5.925,6.117,7.937,5.316,P<0.05).After the application of association rule algorithm model,the average scores of overall utilization efficiency,quality stability efficiency and accurate diagnosis and treatment efficiency of the equipment were(96.39±3.69)points,(94.23±3.06)points and(95.47±4.36)points,respectively,which were higher than those before the application,and the difference was statistically significant(t=16.762,17.919,11.769,P<0.05).Conclusion:The application of the classification management model of medical equipment in public hospitals based on association rules algorithm can realize the classification management of medical equipment in hospitals,improve the operating efficiency and management level of equipment,and reduce the equipment failure rate.

Objective To investigate the effect of extracorporeal membrane oxygenation (ECMO) on critical patients with non-pulmonary primary disease in the emergency department. Methods The literature of English and Chinese clinical studies on the ECMO treating critical patients with non-pulmonary primary disease published before August 2017 were electronically searched on PubMed, Embase and other databases. The obtained articles were selected, their qualities were strictly evaluated, and the in-hospital survival rate, 3-month, 6-month and 1-year survival rate, as well as the average intensive care unit (ICU) and length of hospital stay were extracted. This meta-analysis were performed using RevMan software (Version 5.0, Cochrane collaboration). Results A total of 11 articles (n=3043) were enrolled including 616 cases of ECMO treatment group and 2427 cases of control group. Fitting results showed that compared with the traditional treatment, application of ECMO can improve the in-hospital survival rate[52.1％(321/616) vs. 32.1％ (780/2427); OR=2.02; 95％CI:1.11-3.67, P=0.02] and the survival rate more than 90 days[42.1％ (61/145) vs. 17.1％ (38/222); OR=3.98; 95％CI:2.30-6.89, P<0.01];and prolong the average length of hospital stay (MD=-5.35, 95％CI:-8.10--2.60, P<0.01) and ICU time(MD=-8.99, 95％CI:-8.20--1.80, P<0.01). Conclusions Meta-analysis of existing studies showed that application of ECMO can improve the short-term and long-term prognosis of critical patients with non-pulmonary primary disease. However, due to the small number of studies and the large heterogeneity of the study population, it is necessary to carry out more, large samples and high quality randomized controlled clinical trials.

Objective To comprehensively evaluate the clinical efficacy of hemoperfusion (HP) combined with continuous veno-venous hemofiltration (CVVH) on acute paraquat poisoning (APP).Methods Literatures of Chinese and English randomized controlled trials (RCTs), case control and cohort study on HP combined with CVVH in the treatment of APP from the PubMed, Embase, Wanfang, and CNKI up to November 2017 were enrolled (the subjects were > 16 years old). The obtained literatures were strictly screened and evaluated in quality, and data such as mortality, the life time of dead patients, inefficiency rate, incidence of multiple organ dysfunction syndrome (MODS) and acute respiratory distress syndrome (ARDS) were extracted. Meta-analysis was performed by RevMan 5.3. Results Twenty-one studies were included with 2222 subjects, among whom 976 subjects were in HP combined with CVVH group (experimental group) and 1246 subjects in HP group (control group). Compared with control group, the mortality in experimental group were significantly decreased [43.77％ (362/827) vs. 55.26％ (604/1093), odds ratio (OR) =0.68, 95％ confidential interval (95％CI) = 0.56-0.82,P = 0.0001], the life time of death patients was significantly prolonged [mean difference (MD) = 4.63, 95％CI = 2.60-6.66,P < 0.00001], incidence of MODS [25.93％ (70/270) vs. 55.36％ (155/280),OR = 0.26, 95％CI = 0.14-0.49,P< 0.0001], and incidence of ARDS [30.37％ (82/270) vs. 51.07％(143/280),OR = 0.42, 95％CI = 0.30-0.61,P < 0.00001], and inefficiency rate [8.72％ (13/149) vs. 34.64％ (53/153),OR=0.17, 95％CI = 0.09-0.34, P < 0.00001] were significantly reduced. Funnel chart showed that except the publication bias of mortality rate, there were less publication bias about other indicators among studies.Conclusion HP combined with CVVH can significantly reduce the mortality of patients with APP compared with HP alone on the whole, prolong the life time and reduce the occurrence of MODS and ARDS, thus improving the treatment efficiency.

Objective To observe the effects of dopamine in different doses on hemodynamics and cerebral oxygen metabolism in the early stage of post-resuscitation in rabbit with cardiac arrest.Methods Healthy adult rabbits were randomly(random number) divided into 4 groups according to the different doses of dopamine administration:control group (CG),low dose group (LG),medium dose group (MG),high dose group (HG),(n=15 in each group).Ventricular fibrillation (VF) was induced by electricity and cardiopulmonary resuscitation (CPR) was performed subsequently as the experiment designed.When 10 rabbits with restoration of spontaneous circulation (ROSC) were got each group,it was enough for experiment carried out.Cardiac output (CO),mean arterial pressure (MAP),heart rate (HR),systemic vascular resistance index (SVRI) and the cerebral local tissue blood oxygen saturation (TOI) were observed at 0 min,15 min,30 min,60 min,120 min after ROSC.The animals were sacrificed at 120 min after ROSC,brain tissues were harvested for study by using HE staining.Repeated measure analysis of variance was used to determine the statistical significance among the four groups at different intervals.Multi-group quantitative data was analyzed by one way ANOVA and then further by LSD test for multiple comparisons.Chi-square test or Fisher's exact probabilities was applied for multi-group binomial classification variable.Log-rank test was used for comparisons of survival curves in four groups.A twotailed value of P＜0.05 was considered statistically significant.Results There were no differences in the rate of ROSC among groups.Compared with CG and LG,ROSC time was shorter in MG (277±15 vs.190±12,P＜0.01;252±16 vs.190±12,P=0.016) with higher 120 min survival rate (20％ vs.90％,x2=9.899,P=0.005;30％ vs.90％,x2=7.5,P=0.02).CO was higher in MG than that in other groups at all given intervals in the early stage of post-resuscitation(P＜0.05).MAP levels were significantly higher in MG and HG compared with CG and LG at given intervals 15 min after ROSC (P＜0.05).SVRI was significantly higher in HG than that in other groups at all given intervals after ROSC (P＜0.05).Compared with other groups,the TOI levels in MG were significantly higher than that in other groups at 15 min and 30 min after ROSC (P＜0.05).The median survival time in MG and HG was significantly longer than that in CG and LG.The number of cellular necrosis in MG (28.4±1.0) was significantly fewer than that in other groups (CG 41.2±1.5;LG 41.0±2.0;HG 39.6±1.9) (P＜0.01).Conclusion The moderate dose of dopamine might maintain MAP and CO at a higher level meeting the cerebral oxygen metabolism in the early stage of post-resuscitation from cardiac arrest in rabbits.
