Objective To investigate the causes and influencing factors of dead on arrival (DOA) in children.Methods The clinic data from 66 children with DOA admitted in the emergency department of Hunan Children's Hospital from Jan 2010 to Apr 2012 were analyzed retrospectively.Results All of the 66 cases had cardiac respiratory arrest when admission.Fourteen cases had arrest for 10 minutes,12 cases for 30 minutes to an hour,40 cases had no details.Forty-four (68.2％) cases were carried by parents,22(31.8％)cases were transferred by medical professionals.The main causes of DOA were severe pneumonia with respiratory failure and (or) heart failure,intracranial infection,neonatal diseases.All cases were taken to resuscitation room by triage immediately.Tracheal intubations were completed in 48 cases and intravenous access with injection of epinephrine and other resuscitative drugs were established in all cases,but all cases were dead due to breathing and heartbeat stopped for a long time.Conclusion DOA is one of the important reasons for pediatric high-risk.The key of reduction of DOA incidence and improvement of survival rate is to improve pediatric emergency medical service system,strengthen the health education for the parents,to carry out training and establish homogenization service in emergency ICU.

Objective To observe the curative effect of surgical treatment for eyelid basal cell carcinoma. Design Retrospective case series. Participants 33 cases with eyelid basal cell carcinoma. Methods 33 cases with eyelid basal cell carcinoma treated with surgery, standard excision in 17 case and Mohs micro excision in 16 cases were analyzed, postoperative appearance and function of re- eonstruetiiv eyelid, reeurence rate and survival rate were observed by follow-up survey. Main Outcome Measures Postoperative ap- pearance, function of reconstruetiiv eyelid, recurence rate and survival rate. Results After 6 month ~ 5 years follow-up survey with an average of 2.5 years, 28 of 29 cases obtained normal eyelid appearance, 1 case with lower eyelid gentle ectropium. 11 cases showed hy- perpigmentation in skin-grafting area in early stage, and became normal in half a year. Eyelid function of 29 cases were normal. Tumour relapse was seen in one case 2 years after standard resection,the cure rate was 94.12%. No tumor relapse was seen in group of mohs micro resection, the cure rate was 100%. Within five years postoperation, there was no death case caused by basal cell carcinoma re- lapse, except one dying from myocardial infarction and another dying of eerebrovaseular disease. Conclusions Operational excision is an effective approach for eyelid basal cell carcinoma. The effect of mohs micro resection is better than the one of standard resection. With dissociate skin grafting, fluctuate tarsal transmigration and dissociate skin grafting, eyelid appearance and function recover well.

Objective To investigate the use situation of sunscreen agent in the sunblock cosmetics.Methods Statistic analysis was performed in the kinds,frequencies,dosages of sunsereen agents and the mark dosage coincidence in 414 cosmetics from Sep.2004 to Aug.2007.Results Fourteen kinds of sunscreen agents including phenylbenzimidazole sulphonic acid and its potassium,sodium and triethanolamine salts,benzophenone-4,benzophenone-5,benzophenone-3,isopentyl p-methoxycirmamate, 4-methylbenzylidene camphor,ethylhexyl dimethyl PABA,butyl methoxydibenzoylmethane,octocrylene,ethylhexyl methoxycinnamate,ethylhexyl salicylate,ethylhexyl triazone,methylene bis-benzotriazolyl tetramethylbutylphenol,bis- ethylhexyloxyphenol methoxyphenyl triazine were detected in 414 cosmetics.The use frequency of ethylhexyl methoxycinnamate was above 90%,butyl methoxydibenzoylmethane was 30%,benzophenone-3 and ethylhexyl salicylate were 15% and 11% respectively,and others were less than 10%.The rate of exceed standard limit of ethylhexyl methoxycinnamate,octocrylene, ethylhexyl salicylate,4-methylbenzylidene camphor ethylhexyl dimethyl PABA were 0.24%,0.97%,1.21%,0.48% and 0.24% respectively.The mark dosage coincidence rate of 14 kinds of sunscreen agents were from 42.9% to 89.5%.Conclusion The many kinds of sunscreen agents were used in the sunblock cosmetics,so the special attention should be paid to the cosmetics safety.

Objective To investigate the levels of creatine kinase (CK-MB), brain natriuretic peptide (BNP), and neu-ropeptide Y (NPY) in severe pneumonia pediatric patients combined with heart failure (HF). Methods Pneumonia pediatric patients admitted from December 2010 to December 2014 had been enrolled and divided into pneumonia group (P) (n=32), se-vere pneumonia group (SP) (n=20) and severe pneumonia combined HF group (HF) (n=36). Twenty healthy children served as control group (C). Serum level of CK-MB was detected by enzyme rate method and were measured by ELISA. BNP and NPY were measured again during the recovery period in 18 cases in HF group. Results The serum levels of CK-MB, BNP and NPY were signiifcantly different among the four groups, (F=25.19~277.94, P<0.01). The serum levels of CK-MB, BNP and NPY were signiifcantly higher in HF group than in SP, P and C group (P<0.05). The serum level of CK-MB was signiifcantly higher in SP group than that in P and C group (P<0.05) and there was no difference between P and C group (P>0.05). The serum levels of BNP and NPY were not statistically signiifcant between SP and P and C group (all P>0.05). In HF group, the serum levels of CK-MB, BNP, and NPY were signiifcantly decreased in 18 cases after treatment. The serum level of BNP was positively correlat-ed with CK-MB and NPY (r=0.681, 0.525, all P<0.01) and the NPY and CK-MB levels were also positively correlated (r=0.545, P<0.01). Conclusions The Detection of the serum levels of CK-MB, BNP and NPY can help diagnose severe pneumonia com-bined with HF. The BNP maybe the most sensitive indicator.
