Objective To investigate the clinical features of unintentional injuries in children,and to provide the theoretical basis for preventing and intervening the occurrence. Methods We collected the data of children aged from 0 to 14 years old and hospitalized in the First Affiliated Hospital of Guangxi Medical University from January 2013 to December 2015. Results There were 2286 cases of children including 1507 boys(65. 92%) and 779 girls(34. 08%). The high incidence age was 1 to 3 years with a total of 896 cases(39. 19%). The first five causes of unintentional injuries were burns/scalds 840 cases(36. 71%),fall/drop 464 cases(20. 30%),blunt force injury 290 cases(12. 68%),foreign bodies(in the esophagus,airway, etc) 253 cases(11. 07%),and sharp object injury 153 cases(6. 68%). The unintentional injuries of different age group were varied,for example,the common causes of 1 to 3 years old group were burns /scalds and for-eign bodies(in the esophagus,airway,etc),and the main injuries in 6 to 14 years old group were fall/drop and blunt force. Furthermore, the proportion of unintentional injuries in rural children was 1547 cases (67. 67%),and in the urban children was 739 cases(32. 33%). Unintentional injury with serious conse-quences included burns/scalds 55 cases(26. 96%),sharp object injury 45 cases(22. 06%),burns/scalds 26 cases (12. 75%),blast injury of 23 cases(11. 27%) and fall/drop 20 cases(9. 80%). Disable/sequel hap-pened in 204 cases(8. 92%). Ten cases died(0. 44%) including fall/drop in 4 cases,traffic accident in 3 cases(30%). Conclusion Young children aged 1 to 3 years are the most vulnerable to unintentional inju-ries. Burns/scalds and foreign bodies( in the esophagus,airway,etc) are the most common causes of injuries, and the boys are more common than girls. Moreover,the incidence rate of unintentional trauma in rural chil-dren was higher than that in the urban children. Unintentional injury complicated serious consequences are burns/scalds,sharp object injury,blast injury and fall/drop. Death cases in the majority are fall/drop and traf-fic accident. The key to reduce the occurrence of unintentional injuries is to strengthen propaganda of preven-tion knowledge about the children′s unintentional injuries.

Aim Toinvestigatetheroleofhyperglyce-mia in cerebral ischemia/reperfusion(I/R)injury with a middle cerebral artery occlusion(MCAO)rat model anditsmechanism.Methods EightyhealthymaleSD rats were randomly assigned into sham group, I/R group (normoglycemia),hyperglycemic I/R groupⅠ(HG1 )and hyperglycemic I/R groupⅡ(HG2 ).The cerebral I/R model was established by occluding the middle cerebral artery(MCA)in rats.Hyperglycemia was induced by intraperitoneal injection of 50% glu-cose solution.Neurological deficit was determined by Ludmila Belayev test;infarct size and brain edema were measured by TTC staining;mitophagy was ob-served by double immunofluorescent staining and elec-tron microscope.The expressions of autophagy-related proteins(LC3 and Beclin-1 )and apoptosis-related pro-teins(Cyt-C,AIF,caspase-9 and caspase-3 )were ex-aminedbyWesternblotfurtherly.Results Bloodglu-cose level was controlled at 4 mmol·L-1 (normoglyce-mia),10 mmol · L-1 (HG1 ) and 20 mmol · L-1 (HG2)respectively.There were no significant differ-ences between model group and HG1 group in neuro-logical deficit scores,infarct volume and edema size(P>0. 05 ).However,these indications in HG2 group were significantly increased compared with model group (P<0. 05 ).After 3 days of reperfusion,the level of mitophagy was significantly reduced accompanied with increased mitochondria damages in HG 2 group (P <0. 05 ),and the expressions of mitochondrial related ap-optotic proteins(Cyt-C,AIF,caspase-9 and caspase-3 ) were significantly increased accordingly compared to modelgroup.Conclusions Mildhyperglycemiacan not intensify the cerebal ischemic injury.In contrast, severe hyperglycemia significantly aggravates the brain ischemic injury by inhibiting the removal of injured mi-tochondria in a manner of mitophagy,thus amplifying the mitochondrial mediated cascade damage responses.
