Sentinel lymph node localization and staging with a low-dose of superparamagnetic iron oxide (SPIO) enhanced MRI and magnetometer in patients with cutaneous melanoma of the extremity - The MAGMEN feasibility study

BackgroundIn patients with melanoma, sentinel lymph node (SLN) status is pivotal for treatment decisions. Current routine for SLN detection combines Technetium^99m (Tc⁹⁹) lymphoscintigraphy and blue dye (BD). The primary aim of this study was to examine the feasibility of using a low dose of superparamagnetic iron oxide (SPIO) injected intracutaneously to detect and identify the SLN, and the secondary aim was to investigate if a low dose of SPIO would enable a preoperative MRI-evaluation of SLN status.MethodsPatients with melanoma of the extremities were eligible. Before surgery, a baseline MRI of the nodal basin was followed by an injection of a low dose (0.02–0.5 mL) of SPIO and then a second MRI (SPIO-MRI). Tc⁹⁹ and BD was used in parallel and all nodes with a superparamagnetic and/or radioactive signal were harvested and analyzed.ResultsFifteen patients were included and the SLNB procedure was successful in all patients (27 SLNs removed). All superparamagnetic SLNs were visualized by MRI corresponding to the same nodes on scintigraphy. Micrometastatic deposits were identified in four SLNs taken from three patients, and SPIO-MRI correctly predicted two of the metastases. There was an association between MRI artefacts in the lymph node and the dose SPIO given.DiscussionIt is feasible to detect SLN in patients with melanoma using a low dose of SPIO injected intracutaneously compared with the standard dual technique. A low dose of SPIO reduces the lymph node MRI artefacts, opening up for a non-invasive assessment of SLN status in patients with cancer.     

针刺京骨穴联合推拿治疗背肌筋膜炎临床研究

目的探讨针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效。方法将2016年10月—2018年10月收治的背肌筋膜炎患者86例纳入研究,采用随机数字表法分组。对照组43例予以推拿治疗,观察组43例予以针刺京骨穴联合推拿治疗。比较2组患者的治疗总有效率、VAS评分及Oswestry功能障碍指数、痊愈所用时间。结果观察组治疗总有效率为95.3%,而对照组仅为81.4%,差异有统计学意义(P<0.05);2组治疗后VAS评分、Oswestry功能障碍指数均有下降,观察组上述指标低于对照组,差异有统计学意义(P<0.05);观察组痊愈所用时间短于对照组,差异有统计学意义(P<0.05)。结论针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效突出,可缓解背部疼痛、恢复功能活动,并缩短了愈合时间,提高了生活质量,值得一定的临床推广。     

肌萎缩侧索硬化案

肌萎缩侧索硬化症(ALS)是一种常见的上、下运动神经元同时损害的一种疾病,临床常见肢体无力、肌肉萎缩等症状。属中医学“痿证”范畴,本例验案患者双上肢及左下肢活动无力伴肌肉萎缩2年余,加重半年,伴随肌张力增高、反射亢进等症状,辨证属肝肾亏虚型痿证,临床以针刺治疗为主,配合静脉注射、穴位注射以补益肝肾,养血柔筋,疗效显著。     

针药并用治疗双心疾病的应用

随着对于双心疾病研究的加深,西医疗法的弊端也开始显现。而中医因其理论架构中早就有对于“心主血脉”和“心主神明”的认识,因此在双心疾病的治疗上有着先天的优势。同时近些年中医疗法的结合应用也取得不错的成绩,本文通过对于双心疾病的病例分析,来研讨这种治疗手段的合理性和先进性。     

New and important changes in breast cancer TNM: incorporation of biologic factors into staging

Introduction: Cancer staging has historically been based solely on the anatomic extent of the tumor (T), spread to lymph nodes (N), and the presence of distant metastases (M). More recently biologic factors have been added to modify TNM stage groups to provide more accurate prognosis for patients.

Areas covered: The American Joint Committee on Cancer (AJCC) updated breast cancer staging in 2016 to include T, N, M, tumor grade and expression of estrogen and progesterone receptors and HER2. Addition of these factors changed the stage group for a large fraction of cases compared to prior TNM stage groupings. This updated ‘prognostic stage’ provides more robust and precise prognosis information.

Expert opinion: Inclusion of biological information in staging changes the meaning and the use of stage in clinical practice. This paper reviews the evidence supporting these changes, limitations affecting staging, and discusses the implications for clinical practice and the future of breast cancer staging.     

针刺配合肠炎散保留灌肠治疗肛窦炎临床研究

目的观察肛窦炎应用针刺配合肠炎散保留灌肠治疗的效果。方法选取2017年10月-2018年10月就诊的72例肛窦炎患者,采用随机数字表法分为观察组(n=36)与对照组(n=36)。对照组给予肠炎散保留灌肠治疗,观察组为针刺配合肠炎散保留灌肠治疗,比较2组症状、疗效及安全性。结果观察组症状(放射痛、指诊症状及镜检症状)少于对照组,总有效率高于对照组,差异有统计学意义(P<0.05);2组安全性相比,差异无统计学意义(P>0.05)。结论针对肛窦炎患者,予以针刺配合肠炎散保留灌肠治疗效果确切,可减少临床症状,加快疾病转归,且治疗安全性较好。     

杜元灏教授针刺治疗失眠经验

失眠是由各种原因导致的入睡困难和(或)睡眠维持困难的睡眠障碍,主要特征是睡眠感不满意,属于中医学"不得眠""不寐"范畴。传统多从心、肝、胆、脾、胃、肾论治该病,杜元灏教授认为脏腑机能失调,气血不和,阳不能入阴,阴不能涵阳,神不守舍而致失眠。重视"脑为元神之腑"的理论,且因督脉入络脑,夹脊穴为五脏六腑之气转输、流注之处,杜教授多强调从脑、督脉以及夹脊穴论治失眠,为针刺治疗失眠提供新思路。     

外科治疗ⅢA期N2非小细胞肺癌的预后分析及临床意义

目的 探讨影响ⅢA期N2非小细胞肺癌（NSCLC）预后的因素，并分析经手术治疗不同亚组病人的生存率差异。方法 分析1997年1月至2000年1月146例手术治疗的ⅢA期N2 NSCLC病人的可能影响预后因素：病理类型、肿瘤位置、肿瘤大小、手术方式、临床N2情况，N2转移组数及个数、术后辅助治疗等，并用Kaplan-Meier曲线及Logr ank检验生存率差异，Cox单因素、多因素分析各因素对生存率的影响。结果 ⅢA期N2 NSCLC病人的3年和5年生存率分别为19．86％和14．56％。单因素分析示肿瘤位置、临床N2情况、N2转移组数及个数是影响生存率的因素；多因素分析示肿瘤大小、临床N2情况，N2转移组数和肿瘤位置影响预后。右肺下叶肿瘤单组或单个N2转移，预后最好。结论 纵隔N2转移淋巴结的大小、个数和组数是影响术后生存率主要因素。手术前未发现N2转移（mN2），有1组N2转移（N2h），N2转移数少于4个者手术治疗效果好。右肺下叶肿瘤发生单组N2淋巴结转移预后好。
