RESUMO
Objective@#To learn the characteristics of road traffic injury cases caused by electric bicycles in Changshan County from 2013 to 2016,and to provide evidence for the development of preventive measures or traffic regulations.@*Methods@#The surveillance data of road traffic injuries caused by electric bicycles was collected from the hospital-based product injury monitoring system in Changshan County during 2013-2016. The descriptive epidemiologic analysis on demographic characteristics,body parts and degree of injury was conducted.@*Results@#A total of 7 078 road traffic injury cases caused by electric bicycles were reported from 2013 to 2016,accounting for 49.58% of road traffic injuries. The proportion of electric bicycle injuries was higher in females than in males(P<0.05). There were 4 893 cases aged 30-64 years,accounting for 69.13%;5 562 cases with an education level of junior high school or below,accounting for 78.58%;2 005 cases occurring from July to September,accounting for 28.33%;5 216 cases occurring from 8:00 to 19:00,accounting for 73.69%. The injury mainly lay in head,accounting for 30.77%(2 178 cases). Most injuries were flesh wounds,accounting for 74.96%(5 306 cases). Most cases went home after treatment,accounting for 76.09%(5 386 cases).@*Conclusion@#The incidence of road traffic injury caused by electric bicycles is high in Changshan County. Improving the safety awareness of women and people aged 30-64 years should be focused on.
RESUMO
Objective@#To understand the epidemiological characteristics of product-related injuries among children in Changshan County from 2011 to 2017 and to provide evidence for targeted intervention. @*Methods@#The surveillance data of product-related injuries among children aged below 18 years from 2011 to 2017 was collected from three sentinel hospitals in Changshan County. The characteristics of product-related injuries among children were analyzed,especially those injuries caused by furniture,stationery and sporting goods,commodities and toys. @*Results@#A total of 5 111 product-related injury cases among children were reported,accounting for 13.49% of product-related injury cases of all age. There were 3 138 boys and 1 973 girls,accounting for 61.40% and 38.60%. There were 2 973 cases less than 10 years old,accounting for 58.17%. The main causes of product-related injuries were road traffic injury(49.46%),blunt(16.02%),stab/cut(12.39%)and fall(10.37%). The main categories of products included transportation equipments(not including motor vehicles,36.83%),motor vehicles(17.82%),furniture(12.23%),stationery and sporting goods(8.45%),commodities(4.89%)and toys(3.25%). Stab/cut(53.01%)was the main cause of commodities related injuries;blunt was the main cause of furniture,stationery and sporting goods and toys. The stationery and sporting goods related injuries occurred mainly in schools/public places(64.57%)and sports venues(18.48%)when engaging in sports(54.13%);furniture,commodities and toys related injuries injured cases occurred at home when engaging in leisure activities. Commodities mainly resulted in sharp/bite/open wound(51.50%);furniture,stationery and sporting goods and toys mainly resulted in bruises. Most cases were injured in head,slight and allowed home after treated.@*Conclusion@#The product-related injuries among children in Changshan County are more boys. The products mainly involve transportation equipments(not including motor vehicles),motor vehicles,furniture,stationery and sporting goods,commodities and toys,with emphasis on the latter four categories in the prevention of product-related child injury.
RESUMO
Objective To compare the influence of early weight bearing exercise and plaster fixed method on postoperative function and fracture healing of unstable ankle fracture patients.Methods 50 cases of unstable ankle fracture patients who did surgical treatment in our hospital were selected as the research object,and were randomly divided into an observation group and a control group.The observation group was applied with early postoperative weight bearing exercise,while the control group patients was applied with postoperative plaster fix with 2 weeks.The postoperative function and fracture healing situation of both groups were compared.Results At postoperative 24 hours and 1 week,the perimeter difference of two groups were not statistically different (P>0.05).At postoperative 6 weeks,the perimeter difference was (0.53 ±0.31) cm in the observation group and (1.25±0.47)cm in the control group,the comparative differences was statistical significance (t=6.39,P<0.05).The total effective rate of alleviate swelling in the observation group at postoperative 6 weeks was 96.0%,which was higher than that of the control group (76.0%) with statistical difference (x2=4.15,P<0.05).At postoperative 24 hours,postoperative 1 week and postoperative 6 weeks,the pain index comparison difference between the two groups was not statistically significant (P>0.05).The Baird-Jackson score of the observation group at postoperative 3 months was not different with the control group with statistically significant (P>0.05) ; At the postoperative 6 months,the Baird-Jackson score of the observation group was (95.21 ± 8.25),which was higher than that in the control group (82.52±6.96) with statistical difference (t=5.88,P<0.05).Conclusion The early weight bearing exercise can promote haemal circumfluence,relieve swelling,and be helpful for function recovery and fracture healing of unstable ankle fracture patients.
