ABSTRACT
Objective@#To explore the cumulative effects of unintentional injury among children in rural area, in order to provide information for early intervention of unintentional injury.@*Methods@#Through multistage clustering sampling method, 2 109 primary caregivers of students from 8 rural primary and elementary schools of Heilongjiang Province were recruited. Strengths and Difficulties Questionnaire (SDQ), Injury Behavior Checklist (IBC), Perceptions of Risks and Hazards were used to collect as the risk factors, while Perceptions of Risks and Hazards (PSAPQ), Home Observation for Measurement of the Environment (HOME) and Knowledge, Attitude and Practice for Children Unintentional Injury (KAP) were also used as the protective factors. Risk factors index (RFI) and protective factors index (PFI) were computed in the study.@*Results@#The severity of unintentional injury were positively correlated with SDQ, IBC and perceptions of risks and hazards(r=0.15, 0.23, 0.12, P<0.01), and were negatively correlated with HOME, PSAPQ and KAP(r=-0.25, -0.14, -0.09, P<0.01). Hierarchical linear regression showed that the total scores of SDQ, IBC and environmental of HOME predicted the severity of unintentional injury which could explain 34% variant of unintentional injury. It also indicated that the severity of unintentional injury were positively correlated with RFI (β=0.21) and negatively correlated with PFI(β=-0.18), the interaction was significant(β=-0.11,R2=0.31)(P<0.01).@*Conclusion@#Both risk and protective factors of unintentional injury have cumulative effects on the severity of injury among rural children. The relationship between risk factors and injury could be mediated by protective factors.
ABSTRACT
AIM: To discuss the clinical efficacy of fresh amniotic membrane ( AM ) during the microscopic adjustable suture surgery in children's intercommunity strabismus, in order to guide clinical treatment. METHODS: With the clinical randomized control study (RCT), 60 (112 eyes) cases of patients in childhood who received microscopic strabismus surgery in our hospital were divided them into two different groups from Jan. 2010 to Oct. 2015. According to the application of AM on the basis of ophthalmology outpatient number, 30 cases (58 eyes) in group A were treated with rectus muscle recession surgery combined adjustable suture combined with AM. The other 30 cases (54 eyes) in group B were treated with rectus muscle recession surgery combined adjustable suture only. All patients in two groups were followed-up over 6mo after the strabismus surgery. RESULTS:Twenty-seven cases ( 48 eyes ) of all the strabismus patients must be adjusted after strabismus surgery, and the eye position adjustment rate was 42.9%. At 1mo after surgery, eye position of 18 cases (29 eyes) can be adjusted in all patients, and 44. 8% (16 cases, 26 eyes ) in group A with the average of adjustment lengths was 2. 56±0. 64mm, and 5. 6% ( 2 cases, 3 eyes ) in group B, with the average of adjustment lengths was 0. 52±0. 28mm, the differences of the adjustment rate and the average of adjustment amount were both high statistically significant (χ2 =22.477, P CONCLUSION: The application of fresh AM in the microscopic adjustable suture strabismus surgery is exactly effective in treatment of children's intercommunity strabismus. It can significantly extend the adjustment time and increase the adjustment amount, and it also can statistically improve the controllability and achievement ratio for children's strabismus surgery.
