Objective　The purpose of this study was to investigate the care burden and influencing factors of the primary caregivers for patients with adolescent idiopathic scoliosis ( AIS） treated conservatively, and to explore the correlation between care burden and various factors. The results were expected to provide evidence to clinicians for taking targeted measures to reduce the burden of caregivers and improve the quality of medical care. Methods A total of 56 eligible AIS patients and their primary caregivers were enrolled from West China Hospital of Sichuan University from December 2021 to July 2022. The demographic characteristics of patients and their caregivers were surveyed by self-designed questionnaires; the caregiver burden was assessed by the Caregiver Burden Scale （CBI); the self-efficacy of the caregivers was assessed by the General Self-Efficacy Scale (GSES). The Sobernheim Stress Level Questionnaire-Brace (BSSQ-Brace) and Stress Level Questionnaire-Deformity (BSSQDeformity) were used to investigate the patients’ feelings about wearing the brace and their body image. The Cobb angles of the patient’ s main curve were measured and collected. SPSS 23.0 was used for statistics analysis. Descriptive statistics were used for analysing the general information and questionnaire results, and multiple linear regression was used to explore the main influencing factors of caregiver burden. Results　After conservative treatment, the mean correction of the patient’s main curve was 7.13±5.64°；the CBI score of the primary caregiver was 26.52±10.79, and the multiple linear regression results showed that the influencing factors were GSES score and BSSQ-Brace score (R² = 0.194, F = 7.602, P < 0.01). Conclusions AIS patients have different degrees of increased burden on their primary caregivers during conservative treatment, and the influencing factors significantly related to self-efficacy of the caregivers and patients’ feelings about wearing the brace.

用多重散射团簇(MSC)理论对CO在NiO(100)面吸附的碳Is近边X射线吸收精细结构(NEXAFS)实验谱进行了定量分析，研究了该系统可能出现的吸附模型.MSC方法分析表明CO是以C原子朝下，吸附在衬底的Ni—O键桥上，R-factor（可靠性因子）计算显示C原子的吸附位置距Ni原子0.09nm, CO分子中C原子距衬底的吸附高度为0.31±0.01nm.本文讨论了在NiO表面吸附的CO分子σ键的物理本质.与CO在过渡金属Ni，Cu等表面吸附不同，σ共振对于CO键长的依赖不明显.

In order to investigate the difference transformation characteristics of coal reservoirs' physical properties in Xishan coalfield that resulted from thermal effects of high temperature magmatic intrusion causes，based on basin simulation，combing with several experimental methods including reflectance test，industrial analysis，nuclear magnetic resonance，isothermal adsorption，low temperature nitrogen adsorption，and micro fracture statistics，the coal samples，which were taken at different distances from the magmatic rock，were tested. Results show that the pore shape，pore size，and adsorption law have different characteristics as the distance from the center of magma intruded changes. As the distance from magma changes to shorter，the coal reflectivity increases obviously，volatile reduces and ash content increases，at the same time，the BET and pore volume increases and the gas adsorption capacity shows the regularity from low to high，then to low.In addition，in the dual roles of high temperature and high pressure，coal seam forms a large number of cleat，originating from igneous intrusion，which improves the permeability of coal seam. The above results indicate that the transformation from igneous intrusion to coal reservoir has dual roles for exploration and development. At last，it concludes that the reservoir physical property of Tunlan and Shi Qianfeng areas in the middle-west region of Xishan coalfield are in the best condition. They are the favorable zones for coalbed methane enrichment and high yield. [ABSTRACT FROM AUTHOR]
