In order to overcome the adaptability of electrical stimulation produced by the traditional electro acu-puncture and improve the effects of electro acupuncture, a new type of music electro acupuncture instrument has been designed based on ARM. This article put forward to choose the music as prescription whose spectral density met the 1/f fluctuation law in order to make the patients more comfortable accepting electrical stimulation. What’s more, the music prescription for insomnia had been designed. At last, a total of 23 insomniacs were randomly divid-ed into three groups to verify the therapeutic effects. Clinical tests showed that the scheme in this paper was feasible and the treatment effect was significant.

Objective: To investigate the prevalence of scoliosis among primary and middle school students in Jiaxing City, Zhejiang Province, so as to provide insights into scoliosis control among children and adolescents. Methods: Grade 4 to 6 primary school students and grade 1 to 3 junior high school students were recruited using a stratified cluster sampling method in Jiaxing City in 2019. Participants' demographic characteristics, dietary habits and nutritional status, physical activity, learning environments, reading and writing habits were collected using questionnaires. Scoliosis was screened through general examinations, forward bend test and scoliometer, and scoliosis was diagnosed with whole-spine X-ray scans in an erect position. The prevalence of scoliosis was descriptively analyzed among primary and middle school students. Results: A total of 8 026 primary and middle school students were included, 7 304 valid questionnaires were recovered, with an effective recovery rate of 91.00%. The respondents included 3 667 primary school students (50.21%) and 3 637 junior high school students (49.79%), and included 3 776 boys (51.70%) and 3 528 girls (48.30%). There were 659 participants with initial screening positive for scoliosis (9.02%), and the percentages of positive initial screening of thoracic, thoracolumbar and lumbar scoliosis were 2.93%, 4.56% and 4.56%, respectively. A higher percentage of positive initial screening of scoliosis was diagnosed among participants living in Pinghu City (10.45%), junior high school students (11.74%), girls (11.96%), students with a medical history of anemia (22.44%), students with less than 3 days of moderate-intensity physical activity in the past week (9.46%), students with less than 3 days of walking duration of over 10 minutes in the past week (10.18%), students with daily sitting duration of 5 hours and more in the past week (10.74%), students with their class seats exchanged every semester or month (10.28%), students with daily reading and writing duration of 3 hours and more after school (10.93%) and students with less than 10 cm distance from the chest at reading or writing to the edge of the table (9.67%) (all P<0.05). A total of 218 students received whole-spine X-ray scans in an erect position, 132 participants were definitively diagnosed as scoliosis (60.55%), and the estimated prevalence of scoliosis was 5.46%. Conclusion The percentage of positive initial screening of scoliosis was 9.02% among primary and middle school students in Jiaxing City. Gender, stage of learning, nutritional status, exercise frequency and habits of reading and writing may be factors affecting the development of scoliosis.

Objective To investigate the clinical outcomes of percutaneous kyphoplasty (PKP) for treatment of vertebral compression fractures in perimenpausal women.Methods A total of 53 perimenopausal patients (70 vertebrae) undergone PKP for vertebral compression fractures from January 2007 to May 2014 were analyzed retrospectively by case-control study.Thirty-six patients had single vertebral fractures and 17 two-level vertebral fractures.The fracture segments included 5 T11 vertebrae,14 T12 vertebrae,30 L1 vertebrae,12 L2 vertebrae and 9 L3 vertebrae.Ratio of vertebral compression was 10％-30％.According to treatment difference,the patients were divided into PKP group and non-operation group.In PKP group,there were 30 patients with age range of 44-54 years (mean,51.0 years),and the fracture segments included 13 T11 vertebrae,11 T12 vertebrae,17 L1 vertebrae,7 L2 vertebrae,3 L3 vertebrae.In non-operation group,there were 23 patients with age range of 44-54 years (mean,50.5 years),and the fracture segments included 2 T11 vertebrae,3 T12 vertebrae,13 L1 vertebrae,5 L2 vertebrae,6 L3 vertebrae.Visual analogue scale (VAS),Oswesty disability index (ODI),vertebral compression rate,Cobb angle and bone mineral density change were compared preoperatively,2 weeks,6 months and 3 years after operation.Results All patients were followed up for 6-36 months.VAS and ODI were improved compared with preoperative status in two groups at 2 weeks,6 months and 3 years (P ＜ 0.01).VAS and ODI in PKP group were significantly decreased at 2 weeks and 6 months compared with non-operation group (P ＜ 0.01).The Cobb angle and vertebral compression rate in non-operation group were improved at 6 months compared with those in preoperative status (P ＜ 0.05),and a consistent increase was noted at 3 years,but the difference was not statistically significant (P ＞ 0.05).The Cobb angle and vertebral compression rate in PKP group were reduced at 6 months compared with preoperative status (P ＜ 0.05),and an increase was noted at 3 years,but the difference was not statistically significant (P ＞ 0.05).The Cobb angle and vertebral compression rate in PKP group did not increase at 6 months and 3 years,but they had significant increase in non-operation group (P ＜ 0.05).The body mass index in non-operation group decreased at different degrees at 6 months and 3 years,compared with preoperative status (P ＜ 0.05),while the body mass index reduction in PKP group had no statistically significant difference (P ＞ 0.05).The body mass index reduction in PKP group was less than that in non-operation group at 3 years (P ＜0.01).The body mass index reduction in PKP group was slow and had no statistically significant difference compared with preoperative status (P ＞ 0.05).The body mass index reduction in non-operation group was fast and had significant decrease compared with preoperative status (P ＜ 0.05).Conclusion PKP can relieve pain for vertebral compression fractures in perimenopausal women in short term and long term,and PKP can also improve spinal kyphosis and prohibit the decline of bone mineral density.
