       目的 探究1990—2023年中国人群下背痛（LBP）疾病负担，并预测2024—2040年LBP疾病负担发展趋势，为公共卫生政策制定提供数据支撑。方法 基于GBD2023数据库，采用Joinpoint模型、分解分析（decomposition analysis）量化我国LBP负担变化趋势，最后通过ARIMA（autoregressive integrated moving average model）模型预测未来趋势。结果 2023年我国LBP患病人数达9 532.40万人，发病人数为4 138.36万人，伤残调整生命年（DALYs），虽然患病人数、发病人数及DALYs绝对数较1990年显著增长，但年龄标准化率（ASR）均呈显著下降趋势（AAPC依次为-0.90%、-0.84%、-0.89%）。分解分析表明，人口年龄结构是我国LBP疾病负担增长的主要正向驱动因素，流行病学趋势变化对患病率和DALYs起关键抑制作用，且存在明显性别差异。ARIMA模型预测显示，2024—2040年男性和女性LBP相关ASR将持续下降，但我国女性LBP负担仍高于男性。结论 我国LBP负担沉重，受人口结构、性别差异、行为与职业等多方面因素影响，未来需通过分人群、分职业精准干预及多部门协同，持续降低疾病负担。

     Objective To explore the characteristics of disease burden of low back pain（LBP） in the Chinese population from 1990 to 2023，and predict its development trend from 2024 to 2040，so as to provide data support for the formulation of public health policies．Methods Based on the Global Burden of Disease Study 2023（GBD 2023） database，the Joinpoint model and decomposition analysis were adopted to quantify the changing trend of LBP burden in China．The autoregressive integrated moving average（ARIMA） model was used to predict the future trend，with the data for prediction stratified by gender and age group．Results In 2023，the number of LBP patients in China reached 95.3240 million，the number of incident cases was 41.3836 million，and the disability-adjusted life years（DALYs） were 10.6359 million person-years．Although the absolute numbers of prevalent cases，incident cases，and DALYs increased significantly compared with 1990，the age-standardized rates（ASRs） all showed a significant downward trend（average annual percentage changes were -0.90%，-0.84%，and -0.89%，respectively）．Decomposition analysis revealed that population age structure was the primary positive driving factor for the growth of LBP disease burden in China，while changes in epidemiological trends played a key inhibitory role in prevalence and DALYs，with significant gender differences．ARIMA model prediction indicated that the LBP-related ASRs would continue to decrease in both males and females from 2024 to 2040，but the LBP burden in females would remain higher than that in males in China．Conclusions The baseline burden of LBP in China is heavy，affected by multiple factors such as population structure，gender differences，behavioral and occupational factors．In the future，targeted interventions for specific populations and occupations，as well as multi-sectoral collaboration，are needed to continuously reduce the disease burden．

       目的 探究右美托咪定对腋路臂丛神经阻滞联合肩胛上神经阻滞患者术后反弹性疼痛的影响。方法 收录2024年9月—2025年10月期间我院接受肩关节镜手术治疗的患者，合计收录样本量为150例，将患者随机分为两组（n=150）：常规腋路臂丛神经阻滞联合肩胛上神经阻滞组（N组，n=75）、复合右美托咪定的腋路臂丛神经阻滞联合肩胛上神经阻滞组（D组，n=75）；评价组间反弹性疼痛、术后恢复情况及应急指标差异。结果 术后2 h、6 h、12 h、24 h疼痛视觉模拟量表（VAS）评分D组较N组更低（P＜0.05）。反弹性疼痛发生率D组（5.33%）较N组（20.00%）更低，首次发作时间D组较N组更迟，持续时间D组较N组更短（P＜0.05）。术后补救镇痛次数、阿片类药物用量、非甾体药物使用率D组较N组更低（P＜0.05）。术后首次下床时间和住院时长D组较N组更短，满意度评分D组较N组更高（P＜0.05）。不良反应发生率D组与N组比较，差异无统计学意义（P＞0.05）。术前组间应激反应指标未见明显差异，术后24 h两组均有不同程度的指标变化，但相较N组而言，D组心率、平均动脉压、收缩压、舒张压变化幅度更小（P＜0.05）。结论 右美托咪定用于腋路臂丛神经阻滞联合肩胛上神经阻滞患者，在降低术后疼痛程度及反弹性疼痛发生率、促进术后康复进程有显著价值，对术后不良反应发生率及应激反应的影响较小。

       Objective To explore the effect of dexmedetomidine on postoperative rebound pain in patients with axillary brachial plexus block combined with suprascapular nerve block．Methods From September 2024 to October 2025，150 patients who underwent arthroscopic surgery in our hospital were randomly divided into two groups（n=150）：conventional axillary brachial plexus block combined with suprascapular nerve block group（N group，n=75） and axillary brachial plexus block combined with dexmedetomidine group（D group，n=75）．The differences of rebound pain，postoperative recovery and emergency indicators between groups were evaluated．Results The pain scores at 2 hours，6 hours，12 hours and 24 hours after operation in group D were lower than those in group N（P＜0.05）．The incidence of rebound pain in group D（5.33%） was lower than that in group N（20.00%），the first attack time in group D was later and the duration in group D was shorter than those in group N（P＜0.05）．The times of postoperative salvage analgesia，the dosage of opioids and the utilization rate of non-steroidal drugs in group D were lower than those in group N（P＜0.05）．The time of getting out of bed for the first time and the length of hospitalization in group D were shorter than those in group N，and the satisfaction score in group D was higher than that in group N（P＜0.05）．There was no significant difference in the incidence of adverse reactions between group D and group N（P＞0.05）．There was no significant difference in stress response indexes between groups before operation，and the indexes of both groups changed in different degrees 24 hours after operation，but compared with group N，the changes of heart rate，mean arterial pressure，systolic pressure and diastolic pressure in group D were smaller（P＜0.05）．Conclusions Dexmedetomidine used in axillary brachial plexus block combined with suprascapular nerve block has significant value in reducing postoperative pain and incidence of rebound pain，promoting postoperative rehabilitation process，and has little effect on postoperative adverse reactions and stress response．
