儿童胃石症9例诊治经验

目的 总结儿童胃石症的临床特点及治疗经验.方法 回顾性分析郑州大学第一附属医院2009年6月至2020年6月收治的9例胃石症患儿临床资料.结果 9例胃石症患儿均为女性,年龄为4～13岁,其中8例有异食癖,1例发病前曾大量进食柿子.7例经内镜检查确诊,1例经CT确诊,1例经消化道造影确诊.4例经内镜取石治疗,5例经外科手术治疗,最终8例确诊为毛发性胃石症,1例为植物性胃石症.随访1～2 a,9例患儿均恢复良好,胃石症未复发,贫血及营养不良状况均有不同程度改善.结论 儿童胃石症常见于女童,多伴有异食癖,一经诊断应及时治疗,首选内镜取石,内镜取出失败可考虑外科手术治疗,治疗效果及患儿预后好.     

Barrett’s esophagus: Review of natural history and comparative efficacy of endoscopic and surgical therapies

Barrett's esophagus (BE) is the precursor to esophageal adenocarcinoma (EAC). Progression to cancer typically occurs in a stepwise fashion through worsening dysplasia and ultimately, invasive neoplasia. Established EAC with deep involvement of the esophageal wall and/or metastatic disease is invariably associated with poor long-term survival rates. This guides the rationale of surveillance of Barrett’s in an attempt to treat lesions at an earlier, and potentially curative stage. The last two decades have seen a paradigm shift in management of Barrett’s with rapid expansion in the role of endoscopic eradication therapy (EET) for management of dysplastic and early neoplastic BE, and there have been substantial changes to international consensus guidelines for management of early BE based on evolving evidence. This review aims to assist the physician in the therapeutic decision-making process with patients by comprehensive review and summary of literature surrounding natural history of Barrett’s by histological stage, and the effectiveness of interventions in attenuating the risk posed by its natural history. Key findings were as follows. Non-dysplastic Barrett’s is associated with extremely low risk of progression, and interventions cannot be justified. The annual risk of cancer progression in low grade dysplasia is between 1%-3%; EET can be offered though evidence for its benefit remains confined to highly select settings. High-grade dysplasia progresses to cancer in 5%-10% per year; EET is similarly effective to and less morbid than surgery and should be routinely performed for this indication. Risk of nodal metastases in intramucosal cancer is 2%-4%, which is comparable to operative mortality rate, so EET is usually preferred. Submucosal cancer is associated with nodal metastases in 14%-41% hence surgery remains standard of care, except for select situations.     

有限元法生物力学分析在青少年特发性脊柱侧凸治疗及病因研究中的应用

青少年特发性脊柱侧凸发病率较高且病情复杂,对青少年身心健康可造成显著影响,但其因病因不明,临床尚未形成治疗共识。近年来基于患者医学影像进行仿真建模的有限元法生物力学分析在青少年特发性脊柱侧凸治疗及其病因研究中已经有了一系列的应用。本文即从非手术治疗、手术治疗、病因研究、现有局限等角度对有限元法生物力学分析在青少年特发性脊柱侧凸中的应用进行综述,以期为临床实践及相关研究提供参考。     

宫腔粘连的危害及影响因素

宫腔粘连指因宫腔操作以及感染等因素影响,造成子宫内膜基底层受损,内膜修复过程中形成的宫腔内和(或)宫颈处粘连、闭塞等。患者可出现月经量少、痛经、不孕及反复妊娠丢失等临床症状,孕期有流产、早产、胎盘植入等风险。本文就发生宫腔粘连的影响因素,该疾病对于患者生理、心理和妊娠的影响,以及相关治疗效果的影响因素三方面加以综述。旨在引起同行对宫腔粘连的重视,加强宫腔粘连的预防。

基于红外热成像技术探讨扶正温阳法对阳虚体质的影响

目的 基于红外热成像技术探讨“扶正温阳法”对阳虚质的影响，探讨阳虚质者红外热图的共性规律，分析判断“扶正温阳法”干预阳虚质人群的疗效。方法 纳入30例阳虚质患者给予益气温阳药物在大椎、肾俞（双侧）、命门等进行穴位贴敷，分别在干预前后运用红外热成像技术测定督脉、腰部、腹部、双手及双足局部温度的变化。结果 干预后阳虚体质患者的督脉、腰部、腹部、双手、双足温度均升高（P<0.05），阳虚体质局部温度得以改善。结论 本研究发现“扶正温阳法”可诱发循经热传导现象，通过调节热能代谢而起到调治阳虚体质的作用，红外热成像技术可用来辅助评价阳虚质的治疗效果，对临床指导制定阳虚质人群的干预方案疗效判定具有指导意义。
