Based on the experience in providing emergency medical relief during the occurrence of the disastrous “Yunna” typhoon, the paper discusses the necessity of establishing a medical emergency relief system for regional disasters and ways of perfection. It is thus necessary to set up a multi level response mechanism for medical emergency relief; enhance the overall emergency response ability of the emergency medical service systems in case of disastrous events; work out the strategic layout of networks of medical emergency relief for regional disasters; optimize and rehearse in a planned way the crash programs for medical emergency relief for disasters; reinforce the role of the government in organizing and directing medical emergency relief for disasters; make overall arrangements of emergency relief manpower; and improve relief personnels personal sense and ability of self protection.

Objective To investigate the effect of nCPAP as pre-emptive ventilatory support strategy in severe bronchiolitis. Methods A retrospective analysis was made on cases with nCPAP as pre-emptive ventilatory support strategy for severe bronchiolitis in PICU of our hospital from August 2012 to September 2014. Results Seventy-nine children received nCPAP therapy in our PICU. Overall, nCPAP was successful performed in 69 children, 10 patients required intubations. PaO2 and PaO2/FiO2 in patients received intubations were lower than those in patients received only nCPAP before treatment (P < 0.05). There were significant improvements in PaCO2, PaO2, PaO2/FiO2, respiratory rate and heart rate in the patients received only nCPAP at 12 hours and 24 hours post-treatment (P < 0.05). For the 69 patients with hypercapnia received only nCPAP, PaCO2 was significantly reduced at 2 hours, 12 hours and 24 hours post-treatment (P < 0.01). Conclusion Clinically, nCPAP could improve the oxygenation and hypercapnia of patients with severe bronchiolitis. However, these patients, who suffered from severe bronchiolitis with minor PaO2 or PaO2/FiO2, appeared to require intubation as soon as possible.

Objective To study the clinical efficacy and safety of extracorporeal membrane oxygenation (ECMO) in critically ill neonates.Method From November 2016 to September 2018,the clinical data of 5 cases who received ECMO treatment in NICU of our hospital were retrospectively analyzed.The indication of ECMO was reversible respiratory failure irresponsive to conventional therapy.The treatment mode was V-A ECMO.Oxygenation index (OI),vasoactive-inotropic score,blood lactate before and 24 h after ECMO were recorded.Complications of ECMO were also studied.Paired t-test was used to compare the pre and post treatment parameters.Result Among the 5 cases,4 cases were male and 1 case was female.3 cases were diagnosed with meconium aspiration syndrome,2 cases pulmonary hypertension.OI[(9.5 ± 1.8) vs.(60.6 ± 19.4)],vasoactive-inotropic score[(19.5 ± 12.0) points vs.(204.0 ± 143.8) points]and blood lactate [(2.8 ± 1.5) mmol/L vs.(9.6 ± 3.6) mmol/L]) were all significantly decreased at 24 h after ECMO treatment (P ＜ 0.05).During follow-up,3 cases survived,2 cases died.All the 5 cases showed thrombocytopenia,3 cases developed renal failure and received continuous renal replacement therapy,1 case got intracranial hemorrhage.2 of the 3 survived cases developed neurological impairment and need long term follow-up and rehabilitation therapy.Conclusion ECMO treatment has remarkable effects on critically ill neonates and may actually save lives,but the risk of complications are quite high.

OBJECTIVETo investigate whether or not the gamma-aminobutyric acid (GABA) receptor subtype A genes GABRA5 and GABRB3 are associated with childhood absence epilepsy (CAE).

METHODSTwo microsatellite DNA, GABRA5 and GABRB3, adjoining to chromosome 15q11.2-q12 were used as genetic markers. Both case-control study and transmission/disequilibrium test (TDT) as well as fluorescence-based semi-automated genotyping technique were used in 90 trios with CAE and 100 controls to conduct association analysis.

RESULTSThe allele frequencies of the 2 microsatellite DNA in Chinese normal population are in good agreement with Hardy-Weinberg equilibrium. The polymorphism information content of microsatellite DNA GABRA5 and GABRB3, are 0.80 and 0.66 respectively. The allele 2 frequency of microsatellite DNA GABRA5 and the allele 5 frequency of microsatellite DNA GABRB3 are significantly higher in CAE patients than those in normal controls(P<0.001).

CONCLUSIONBoth microsatellite DNA GABRA5 and GABRB3 are good genetic markers. The gamma-aminobutyric acid receptor subtype A genes GABRA5 and GABRB3 may be directly involved either in the etiology of CAE or in linkage disequilibrium with disease-predisposing sites.

Guideline or consensus for the vaccination of children with special conditions like immunocompromised children may be more suitable for pediatricians.However, the vaccination of children in China is mainly performed by general practitioners or child health care practitioners in community health service centers.They need to master the screening knowledge of contraindications and precautions for the vaccination of children, and make the decision to referral to specialists.Based on the technical guidelines for Immunization of National Health Commission of the People′s Republic of China, Best Practices Guidance of the Advisory Committee on Immunization Practices and contraindications and precautions proposed by the Immunization Action Coalition, 20 suggestions for primary screening of children with vaccination contraindications and referral recommendations for primary care providers were developed by experts from the Integration of Medicine and Prevention in Children of Health Commission of Shenzhen Municipality.
