目的 探讨单光子计算机断层扫描仪(SPECT)对抑郁症的疗效评估价值。 方法 2006年5月-2007年12月，选取32例未经治疗的原发性中、重度抑郁症患者，给予氟西汀治疗10周。治疗后根据临床疗效总评量表和汉密尔顿抑郁量表(HAMD)减分率作为疗效评定指标，将患者分为有效组21例，无效组11例。对所有患者于治疗前和治疗后分别进行99m锝-双半胱乙酯(99mTc-ECD)脑灌注显像。静脉注射99mTc-ECD 1 110 MBq，30 min后行脑断层显像，对显像结果分别进行目测及半定量分析两种方法进行判断。 结果 抑郁症患者出现的脑血流灌注减低区主要集中在前额叶、扣带回，经过治疗后好转的抑郁症患者脑血流灌注明显改善。可通过脑血流灌注显像评估抗抑郁治疗的疗效，左前额叶血流灌注越低，对氟西汀治疗效果越好。 结论 SPECT显像技术可视性较好，可用于评估抗抑郁治疗的疗效。
Objective To explore effectiveness of arthroscopic Eden-Hybinette procedure with Triple-Pulley and four point anti-rotation fixation technique in the treatment of recurrent anterior dislocation of shoulder joint. Methods A clinical data of 14 patients with recurrent anterior dislocation of shoulder joint and glenoid bone defect, who were met the selective criteria and admitted between February 2021 and February 2022, was retrospectively analyzed. All patients were treated with arthroscopic Eden-Hybinette procedure and the bone blocks were fixed by using Triple-Pulley and four point anti-rotation fixation technique. There were 9 males and 5 females with an average age of 31.2 years (range, 22-40 years). Shoulder dislocation occurred 4-10 times (mean, 6.8 times). The time from the initial dislocation to the admission was 1-6 years (mean, 3.3 years). The Instability Severity Index Score (ISIS) was 7.2±0.8, the Beighton score was 2.9±2.4, and the width ratio of glenoid bone defect was 26.64%±1.86%. Pre- and post-operative visual analogue scale (VAS) score, the University of Califonia at Los Angeles (UCLA) shoulder score, Constant score, and American Association of Shoulder and Elbow Surgeons (ASES) score were used to evaluate shoulder pain and function. The position, healing, resorption, and remodeling (glenoid area) of the bone blocks were evaluated by CT of shoulder joint. ResultsAll patients underwent surgery successfully without any serious complications. All patients were followed up 11.5-13.8 months (mean, 12.0 months). The VAS scores of shoulder joint after operation decreased compared to preoperative levels, while the UCLA score, Constant score, and ASES score all increased, with significant differences (P<0.05). And with the prolongation of time, the above indicators further improved, and the differences between different time points were significant (P<0.05). Imaging reexamination showed that the bone block completely filled the glenoid defect, with good position and no significant displacement. Over time, the bone block healed and partially absorbed and remodelled. The postoperative glenoid area increased significantly compared to preoperative area (P<0.05). With the prolongation of time, the glenoid area significantly decreased, but the difference was not significant between different time points (P>0.05).Conclusion For the recurrent anterior dislocation of shoulder joint, Triple-Pulley and four point anti-rotation fixation technique in Eden-Hybinette procedure can effectively prevent bone rotation, make fixation more reliable, and easy to operate and achieve good effectiveness.
