D-二聚体和中性粒细胞/淋巴细胞比值评估卵巢癌预后的临床价值

目的:研究D-二聚体（D-dimer,D-D）和中性粒细胞/淋巴细胞比值（neutrophil to lymphocyte ratio,NLR）与卵巢癌临床病理特征及预后的关系。方法:回顾性分析2012年1月至2015年12月于我院妇科行手术治疗的卵巢恶性肿瘤患者387例和卵巢良性肿瘤患者250例临床资料。比较血清D-D和外周血NLR在卵巢良、恶性肿瘤中的表达水平；确定D-D和NLR临界值，D-D+NLR=0（D-D≤0.555 mg/L和NLR≤2.792）,D-D+NLR=1（D-D>0.555 mg/L或NLR>2.792），D-D+NLR=2（D-D>0.555 mg/L和NLR>2.792），分析两者联合的评分系统与卵巢癌临床病理特征和预后的关系。结果:血清D-D和外周血NLR在卵巢良、恶性肿瘤患者中的表达水平有统计学差异（P＜0.001）。D-D高水平组与低水平组相比，患者的分期、分级、淋巴结转移、腹水、CA125水平、残余瘤大小有统计学差异（P＜0.05）。NLR高水平组与低水平组相比，患者的年龄、分期、淋巴结转移、腹水、CA125水平、残余瘤大小有统计学差异（P＜0.05）。D-D+NLR为0、1、2分的平均总生存期（OS）分别为70个月、58个月、40个月。D-D+NLR评分是影响OS的独立预后因素。结论:术前血清D-D和外周血NLR与卵巢癌临床病理特征和OS相关，D-D+NLR评分可以作为评估卵巢癌预后的指标。     

乳腺弥漫大B细胞淋巴瘤临床特点及预后分析

目的:探讨乳腺弥漫大B细胞淋巴瘤（DLBCL）患者的临床特征及预后。方法:回顾性分析2014年5月起至2018年12月我院收治的18例乳腺DLBCL患者的临床特点及预后。结果:在18例患者中，17例为女性，中位年龄为57岁，病变主要累及右侧乳腺（11/18，61.1%）。将其分为原发性乳腺DLBCL（PB-DLBCL）和继发性乳腺DLBCL（SB-DLBCL）两大类。11例（57.6%）PB-DLBCL与7例（42.4%）SB-DLBCL相比，其具有Ann Arbor分期多为Ⅰ-Ⅱ期（P＜0.01）、B症状少（P=0.013）、相对更高的白细胞计数（P=0.041）、骨髓未累及（P=0.043）、完全缓解（CR）率高（P=0.049）等特点。生存分析发现PB-DLBCL患者5年总生存期（OS）显著长于SB-DLBCL患者（P=0.013）。本研究以非生发中心B细胞型（non-GCB）居多，生发中心型（GCB）与non-GCB型之间OS无显著差异（P=0.885）。所有获得CR患者的生存期均显著延长（P=0.008）。结论:乳腺DLBCL多见于中年女性，以右侧乳腺肿块为主要临床表现，分子分型多为non-GCB型。与SB-DLBCL患者相比，PB-DLBCL患者具有Ann Arbor分期早、B症状少、相对更高的白细胞计数、骨髓未累及、CR率高等特点，并且生存期显著延长。无论是PB-DLBCL和SB-DLBCL，还是GCB型和non-GCB型，获得CR提示预后良好。     

脑血管疾病后Holmes震颤的临床、影像和电生理特点

目的 总结脑血管疾病后Holmes震颤的临床、影像和电生理特点。 方法 回顾性分析2015年8月-2019年8月就诊于首都医科大学附属北京天坛医院的4例脑血管疾病 所致Holmes震颤患者，对其临床、影像及电生理资料进行分析总结。 结果 4例患者中2例由高血压性脑出血引起，另外2例分别由脑动静脉畸形和脑海绵状血管瘤破裂 出血引起。Holmes震颤出现于原发病后1～24个月，表现为病灶对侧肢体震颤，以上肢多见。头颅MRI 检查显示2例患者病灶仅累及丘脑，2例同时累及丘脑和中脑。震颤分析显示静止、姿势、意向及持物 1000 g几种状态下震颤的峰频率均在2.6～3.8 Hz，意向状态震颤半宽功率高于静止状态。主动肌与 拮抗肌在静息时以同步收缩为主，姿势、意向和持物时以交替收缩为主。3例接受普拉克索治疗均有 不同程度缓解。 结论 Holmes震颤多由累及中脑、丘脑部位脑血管疾病引起，表现为2～4 Hz低频震颤，意向状态震 颤明显，部分患者多巴胺受体激动剂治疗有效。     

嵌顿痔不同治疗方法疗效分析

目的探讨嵌顿痔不同治疗方法的疗效。方法回顾性分析2009年8月至2012年8月迁西县人民医院确诊为嵌顿痔的160例患者的临床资料,其中采取外剥内扎法的80例患者作为A组,吻合器痔上黏膜环切术(PPH)结合外痔血栓剥除术的80例患者作为B组。对比分析两组患者的手术时间、住院时间、住院费用等指标及临床疗效,对比分析两组术后6个月并发症发生情况。结果B组患者的手术时间、住院时间显著少于A组[(15.4±1.1)min比(38.7±0.5)min,(5.3±0.6)d比(12.4±1.3)d,P<0.01];B组患者的有效率显著高于A组(88.8%比66.3%),而总体并发症发生率及复发率显著低于A组(17.5%比33.8%,5%比18.8%,P<0.05)。结论 PPH结合外痔血栓剥除术临床疗效显著。     

The Long-Term Effective Rate of Different Branches of Idiopathic Trigeminal Neuralgia After Single Radiofrequency Thermocoagulation: A Cohort Study

To evaluate the efficacy of computed tomography (CT) guided single radiofrequency thermocoagualtion (RFT) in 1137 patients with idiopathic trigeminal neuralgia after a follow-up period of 11 years, specially focused on duration of pain relief in different branches of trigeminal nerve, side effect, and complications.Retrospective study of patients with idiopathic trigeminal neuralgia treated with a single CT guided RFT procedure between January 2002 and December 2013.The mean follow-up time was 46.14 ± 30.91 months. Immediate postprocedure pain relief was 98.4%. V2 division obtained the best pain relief rate: 91%, 89%, 80%, 72%, 60%, and 54% at 1, 3, 5, 7, 9, and 11 years, respectively. No statistical difference pairwise comparison was in other groups. The complications included masseter muscle weakness, corneitis, diplopia, ptosis, hearing loss, limited mouth opening, and low pressure headache. Masticatory weakness mostly occurred in patients with V3 branch involvement, while Corneitis and Diplopia all in patients with V1 branch involvement. No mortalities observed during or after RFT.All different branches division of trigeminal neuralgia achieved comparable satisfactory curative effect; V2 obtained the best excellent pain relief, after RFT procedure. Facial numbness is inevitable after RFT, which patients who have pain in all 3 trigeminal divisions and patients who desire no facial numbness should be cautious. Masticatory weakness is mainly related with V3 injured, while Corneitis and Diplopia in patients with V1 injured by RFT.     

Next-generation sequencing through multigene panel testing for the diagnosis of hereditary epidermolysis bullosa in Chinese population

Epidermolysis bullosa (EB) is a heritable blistering disorder. We performed a next-generation sequencing-based multigene panel test and successfully predicted 100% of the EB types, including, 36 EB simplex (EBS), 13 junctional EB (JEB), 86 dystrophic EB (DEB), and 3 Kindler EB. Chinese JEB and recessive DEB (RDEB) patients have relatively mild phenotypes; for severe type separately accounts for 45.5% and 23.8%, respectively. We identified 96 novel and 49 recurrent pathogenic variants in 11 genes, although we failed to detect the second mutation in one JEB and five RDEB patients. We identified one novel p.E475K mosaic mutation in the clinically normal mother of one out of 13 EBS patients with KRT5 mutations, one recurrent p.G2034R mosaic mutation, and one novel p.G2043R mosaic mutation in the clinically normal relatives of two out of 19 dominant DEB patients. This study shows that next-generation technology could be an effective tool in diagnosing EB.
