目的 评估内镜下切开联合丝裂霉素C注射治疗复发性食管良性狭窄的疗效和安全性。方法 对2021年6月—2022年5月在厦门大学附属中山医院消化内科接受内镜下切开联合或不联合丝裂霉素C注射的43例复发性食管良性狭窄患者进行回顾性分析,分为切开组与切开联合丝裂霉素C注射组,对比2组间狭窄缓解率、并发症及预防狭窄复发的效果。结果 2组患者均顺利完成治疗,无严重并发症发生。2组患者治疗后狭窄缓解率无显著差异（P>0.05）。随访12个月,切开联合丝裂霉素C注射组在狭窄缓解时长、狭窄复发再次扩张次数及扩张间隔均优于切开组（P<0.05）。结论 内镜下切开联合丝裂霉素C注射治疗安全、有效,虽然治疗后狭窄缓解率与单纯切开无显著差异,但可延长狭窄缓解期,改善狭窄复发后重复扩张的频率及间隔时间。

Objective To evaluate the efficacy and safety of endoscopic incision combined with mitomycin C injection in the treatment of recurrent benign esophageal stenosis．Methods A retrospective analysis was conducted on 43 patients with recurrent benign esophageal stenosis who received endoscopic incision combined with or without mitomycin C injection in the Department of Gastroenterology,Zhongshan Hospital of Xiamen University from June 2021 to May 2022．Patients were divided into incision group and incision combined with mitomycin C injection group．The stenosis remission rate,complications and preventive effect of stenosis recurrence were compared between the two groups．Results All patients in the two groups successfully completed the treatment without serious complications．There was no significant difference in the stenosis remission rate between the two groups after treatment（P>0.05）．In the follow-up 12 months after treatment,incision combined with mitomycin C injection group was better than incision group in the duration of stenosis remission,the number of stenosis recurrence and dilation interval（P<0.05）．Conclusions Endoscopic incision combined with mitomycin C injection is safe and effective．Although the remission rate of stenosis after treatment is not significantly different from that of incision alone,it can prolong the remission period of stenosis and improve the frequency and interval of repeated dilation after stenosis recurrence．

帕金森病（PD）是一种常见的与年龄相关的神经退行性疾病,其特点是黑质致密部内多巴胺能神经元的进行性丢失以及路易小体的积累。多巴胺能神经元的退化导致纹状体的多巴胺水平降低,最终出现静息性震颤、运动迟缓、肌肉僵硬和姿势不稳等运动症状,以及认知能力下降、嗅觉功能受损、精神异常和睡眠障碍等非运动症状。由于人口结构转变和全球老龄化,PD的不断增加对患者、家庭和社会构成重大负担。尽管广泛的研究已阐明了PD的病因学和潜在机制,但现有治疗主要集中在症状管理,无法阻止疾病的进展。小胶质细胞作为脑内重要的免疫细胞,对维持中枢神经系统的稳态具有关键作用。本文综述了PD研究,包括其病因学因素、分子机制和现有治疗策略。此外,审视了在PD样模型中涉及小胶质细胞的研究,深入探讨了小胶质细胞在疾病进展中的动态,并探究了小胶质细胞在促进或减轻疾病进展方面所扮演的错综角色。通过这样的探讨,本综述旨在为PD复杂的发病机制提供新的洞见和观点,激发出针对性治疗干预的创新思路。

Parkinson's disease（PD）,a prevalent age-related neurodegenerative disorder,is characterized by the progressive loss of dopaminergic neurons within the substantia nigra compacta（SNc）and the accumulation of Lewy bodies．The degeneration of dopaminergic neurons leads to diminished striatal dopamine levels,culminating in motor symptoms such as resting tremors,bradykinesia,muscle rigidity and postural instability,alongside non-motor manifestations encompassing cognitive decline,impaired olfactory function,psychological abnormalities and sleep disturbances．The escalating incidence of PD due to shifting demographics and global aging poses substantial burdens on patients,families and society．Although extensive research has elucidated the etiology and underlying mechanisms of PD,available treatments largely focus on symptom management and lack the capacity to halt disease progression．Microglia,as integral immune cells within the brain,wield pivotal influence over central nervous system homeostasis．This review presents a comprehensive synthesis of PD,encompassing its etiological factors,molecular mechanisms,and existing therapeutic strategies．Furthermore,we scrutinized research involving microglia in PD-like models,delving into the dynamics of microglia in disease progression and probing into the intricate roles that microglia assume in either fostering or mitigating disease advancement．By doing so,this review aims to furnish novel insights and perspectives that shed light on the intricate pathogenesis of PD,potentially sparking innovative concepts for targeted therapeutic interventions．

目的 探讨经尿道前列腺双极等离子电切术(bipolar plasmakinetic resection of prostate,BPRP)与经尿道前列腺钬激光剜除术(holmium laser enucleation of prostate,HoLEP)治疗大体积良性前列腺增生症的临床效果。方法 选择2018年1月—2021年1月本院收治的大体积良性前列腺增生症患者82例,以随机数字表法分为观察组(41例,HoLEP)、对照组(41例,BPRP),比较两组患者手术指标、前列腺症状、生活质量及术后并发症情况。结果 手术指标相比,观察组手术时间(P=0.020)、膀胱冲洗时间(P=0.027)、留置导尿管时间(P=0.007)、术后住院时间(P=0.033)均短于对照组;前列腺症状评分相比,观察组与对照组术前评分无差异(P=0.655),观察组术后半年评分低于对照组(P=0.001);生活质量评分相比,观察组与对照组术前评分无差异(P=0.492),观察组术后半年评分低于对照组(P=0.001);术后并发症发生率对比,观察组总发生率9.76%低于对照组31.71%(P=0.014)。结论 在大体积良性前列腺增生症患者治疗时,HoLEP与BPRP 2种术式均安全有效,但前者手术时间更短,患者预后更快,患者术后恢复时间更短,值得推广。

目的 分析经腹部浅表超声检查对急性阑尾炎患者检出率的影响。方法 选取濮阳市人民医院2018年12月—2020年6月疑似急性阑尾炎患者146例,均行腹部超声、浅表超声检查,以术后诊断为金标准,比较腹部、浅表超声单独及联合诊断效能、对不同类型急性阑尾炎检出率,分析不同类型急性阑尾炎影像学结果。结果 以术后诊断为金标准,146例疑似急性阑尾炎患者中阳性87例,阴性59例;腹部超声检出阳性80例,阴性66例;浅表超声检出阳性91例,阴性55例;腹部浅表超声检出阳性86例,阴性60例;腹部浅表超声诊断急性阑尾炎准确度99.32%(145/146)、灵敏度98.85%(86/87)、特异度100.00%(59/59)高于腹部超声[70.55%(103/146)、71.26%(62/87)、69.49%(41/59)]及浅表超声[69.86%(102/146)、77.01%(67/87)、59.32%(35/59)]单独诊断,漏诊率1.15%(1/87)、误诊率0.00%(0/59)低于腹部超声[28.74%(25/87)、30.51%(18/59)]及浅表超声[22.99%(20/87)、40.68%(24/59)]单独诊断(P＜0.05);腹部浅表超声对不同类型急性阑尾炎总检出率高于单独检查(P＜0.05)。结论 腹部浅表超声应用于急性阑尾炎诊断,可提高诊断准确度、灵敏度、特异度,降低漏诊率及误诊率,对不同类型急性阑尾炎检出率提高有积极作用,可收集患者详细声像信息,为临床治疗方案制定提供方向。

目的 对比分析胆囊癌与非胆囊癌的CT图像,探讨CT定量技术在胆囊癌临床诊断的应用价值。方法 选取就诊于我院进行胆囊手术的248名患者,分析CT征象,比较胆囊癌患者与非胆囊癌患者的相关CT征象差异,回归分析胆囊癌与这些征象的相关性和诊断方面的敏感度和特异度等。结果 在本次选取的248名患者中,胆囊病变类型、增厚类型和程度、动脉期CT值与同期肝实质的比较、是否伴有黏膜不完整和淋巴结肿大、以及临近胆囊周围肝实质的情况与胆囊癌、非胆囊癌的CT图像差异有关(P＜0.05)。经过回归分析,发现胆囊黏膜不完整、动脉期CT值高于肝实质与胆囊癌有较高的相关性,两种征象结合诊断有利于提高CT诊断胆囊癌的准确性,能够较好的分辨出胆囊癌患者与非胆囊癌患者。结论 如患者在CT图像中出现动脉期CT值高于肝实质及胆囊黏膜不完整的情况,则患者多半患有胆囊癌。

目的 探讨CT混合征和岛征及其联合征象对脑出血早期血肿扩大的临床预测价值。方法 将2018年12月—2020年12月河南宏力医院收治的脑出血患者86例作为研究对象,按照有无血肿扩大分为早期血肿扩大组(38例)和血肿未扩大组(48例)。分析CT平扫的岛征、混合征及联合征象对早期血肿扩大的影响,使用ROC曲线及曲线下面积(area under the curve,AUC)比较混合征、岛征及联合征对脑出血后血肿扩大的诊断效能。结果 混合征、岛征、联合征象诊断血肿扩大的灵敏度分别为65.79%、50.00%、84.21%,特异度分别为72.92%、83.33%、93.75%,阳性预测值分别为65.79%、70.37%、91.43%,阴性预测值分别为72.92%、67.80%、88.24%。不同影像学征象诊断血肿扩大的灵敏度、特异度、阳性预测值和阴性预测值差异均具有统计学意义(P<0.05)。ROC曲线分析中,混合征、岛征、联合征象诊断血肿扩大的AUC分别为0.690、0.656和0.811,P均小于0.05,其中联合征象的AUC最大。结论 CT征象中的混合征和岛征分别对脑出血早期血肿扩大的患者进行有效的预测,但相较于单独征象而言,二者的联合征象的诊断效能更高,对患者早期是否出现血肿扩大的现象诊断效能更具有科学性、高效性,为临床后期的治疗提供指导意义,同时也对患者疾病的恢复及预后起到积极作用。
