Objective To analyze the current status of occupational stress among primary and secondary school teachers, and explore the dose-response relationship between weekly work hours and occupational stress. Methods A total of 1 252 teachers from 13 primary and secondary schools in three prefecture-level cities of a central province of China were selected as the research subjects by the convenience sampling method. The Core Occupational Stress Scale was used to assess occupational stress levels of the teachers. Multivariate logistic regression analysis combined with restricted cubic spline models was applied to study the dose-response relationship between weekly work hours and occupational stress. Results The average weekly work hours were (55.3±15.9) hours, with 78.6% of teachers working more than 40.0 hours per week. The total score of occupational stress was (40.3±8.2) points, and the detection rate of occupational stress was 29.8%. Multivariate logistic regression analysis combined with restricted cubic spline models revealed a linear dose-response relationship in weekly work hours and occupational stress among teachers (P for overall trend <0.05, P for nonlinearity was 0.22). Result of age-stratified analysis showed that weekly work hours had a linear dose-response relationship with occupational stress risk in teachers aged 21-<31 and 31-<46 years (P for overall trend <0.05, P for nonlinearity was 0.71 and 0.27, respectively). However, no association was found between weekly work hours and occupational stress risk among teachers aged ≥46 years (P for overall trend =0.08, P for nonlinearity was 0.09). Conclusion There is a linear dose-response relationship between weekly work hours and occupational stress among primary and secondary school teachers in the province, with younger teachers being more susceptible to suffer occupational stress due to long working hours.

: Objective To evaluate the value of rehabilitation direction for the treatment of the children with spastic cerebral palsy. Methods 116 children with spastic cerebral palsy were investigated. 56 children who accepted rehabilitation direction and training in family participated in study group and 60 children who wouldn't accept rehabilitation direction participated in control group. All the children received comprehensive rehabilitation treatment in hospital, including physical therapy, acupuncture, low frequency electrotherapy and occupational therapy. All the children were assessed with Gross Motor Function Measure-88 (GMFM) before and 3 months after treatment. Results There was a significant difference before and after treatment in scores of GMFM in each dimension and total in both groups (P<0.01), and the treatment group improved more than control group(P<0.05). Conclusion Rehabilitation direction can facilitate the recovery of spastic cerebral palsy children.

Objective To observe the effect of traditional Chinese medicine vapor bath combined with function training on children with spastic cerebral palsy(CP).Methods 84 cases with spastic CP were divided into the treatment group(39 cases treated by traditional Chinese medicine vapor bath combined with function training treatment)and control group(43 cases treated with function training treatment mainly).Results The total effect rates were 84.6% in the treatment group and 65.1% in the control group with a significant difference between two groups(P<0.05).The muscle tension of the children in the treatment group was lower than that in the control group(P<0.05).Conclusion The traditional Chinese medicine vapor bath can reduce the muscle tension of children with spastic CP.

Objective To investigate the incidence rate of auditory nerve way injury in children with cerebral palsy (CP) and the relationship with sexes, CP types and risk factors.MethodsThe clinic data of 963 children with CP were reviewed to find out the incidence rate of auditory nerve way injury in CP children and the relationship with sexes, CP types and risk factors.ResultsIn 963 CP children, the incidence rate of auditory nerve way injury was 24.5% (236/963), there was no sexes difference ( P>0.05), but there was a significant difference among different CP types ( P<0.05), athetosis and mixed CP had higher incidence rate ( P<0.01). Furthermore, pathological jaundice was high risk factor ( OR=2.0279, 95%CI:1.483～2.774).ConclusionCP children are often complicated with auditory nerve way injury, it not relate with sexes, but with CP type, athetosis and mixed CP have a higher incidence rate of auditory nerve way injury, and the pathological jaundice is a high risk factors.
