Objective@#To investigate the awareness and identify the influencing factors of sexual knowledge among primary and middle school students in Butuo County, Sichuan Province, so as to provide insights into sex education.@*Methods@#Six primary and middle schools were randomly sampled from 40 primary and middle schools in Butuo County using the cluster sampling method on March and April, 2021, and a class was randomly sampled from each of grades 4 to 6 of primary schools and grades 1 to 3 of junior high schools, with all students from the class as study subjects. Students' demographic features and awareness of sexual knowledge were investigated using self-designed questionnaires, and the factors affecting the awareness of sexual knowledge were identified among primary and middle school students using multivariable linear regression analysis.@*Results@#A total of 980 questionnaires were allocated, and 957 valid questionnaires were recovered, with an effective recovery rate of 97.65%. The respondents included 458 boys ( 47.86% ) and 499 girls ( 52.14% ), and included 908 students with Yi Ethnicity. The respondents included 802 primary school students ( 83.80% ) and 155 junior high school students ( 16.20% ). The awareness of sexual knowledge was 21.94% among the primary and middle school students, and their sexual knowledge was predominantly derived from parents ( 338 students, 35.32% ) and teachers ( 335 students, 35.01% ). The awareness of sexual knowledge was significantly lower in boys than in girls ( 17.69% vs. 25.86%; χ2=8.344, P=0.004 ), and the awareness of sexual knowledge appeared a tendency towards a rise with age ( χ2trend = 63.908, P<0.001 ). Low awareness of sexual knowledge was seen in students with fathers going out for labor ( 19.54% ), mothers going out for labor (11.24%) and living in the countryside ( 14.32% ) ( χ2=7.790, 9.224 and 34.144, all P<0.01 ). Multivariable linear regression analysis showed that students living in the countryside, students’ mothers going out for labor, ages of 12 to 14 years and ages of over 14 years were factors affecting the score of sexual knowledge ( β'=-0.072, 0.341, 0.645 and 0.843, all P<0.05 ).@*Conclusions@#The awareness of sexual knowledge is low among primary and middle school students in Butuo County. Health education of sexual knowledge should be emphasized on male students, those living in the countryside and students with mothers going out for labor.

Comparative analysis of interbody micromorselized bone graft and structure bone graft fusions for treat-ment of single-segment spinal tuberculosis / 实用医学杂志

Objective To compare the infusion outcome of the posterior interbody autogenous micromor-selized bone graft and structure bone graft ,which were used to cure single-segment spinal tuberculosis. Methods The posterior focus debridement and bone graft fusion were conducted on 35 single-segment spinal tuberculosis patients who were cured by micromorselized bone graft and structure bone graft in the hospital from January 2010 to June 2015. Sixteen patients received micromorselized bone graft cases and 19 patients received structure bone graft. According to JOA and VAS,the fusion effects were compared and analyzed in the following aspects,such as opera-tion time,blood loss volume during the operation,kyphosis distorted Cobb angles before and after the operation and fusion time. Results Follow-up visits were paid to all 35 patients and lasted for 12 to 24 months with an aver-age visit time of 18.5 months. Spinal grafted bones showed desirable fusion without invalid screws and grated bones in the spinal canal.(1)No statistical differences were observed between two groups in terms of post-operation JOA and VAS scores.(2)The operation time and blood loss amount during the operation were smaller in the micromor-selized bone graft than those in the structure bone graft ,with significant differences between 2 groups.(3)No sig-nificant differences were observed between the two groups in terms of kyphosis distortion angle ,but regarding to loss of Cobb angles in different intervals after the operation ,it′s greater in the former group than that in the latter one. (4)No significant differences between the two groups in terms of fusion time were observed. Conclusions The two fusion approaches demonstrated no prominent difference in alleviation of the clinical symptoms and the fu-sion time. The micromorselized bone grafting was superior to the structure bone graft in aspects such as operation time and blood loss amount. However ,it′s more likely for the former to lose Cobb angles in the follow-up visits. Both of the two grafting methods were effective in the single-segment spinal tuberculosis operation. All patients ex-cept those with severely unstable spines and osteoporosis and those were too old can adopt the micromorselized bone grafting approach.
