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.     

PBL教学法在临床心肺复苏术教学中的应用分析

目的 分析重症医学科PBL教学法在临床心肺复苏术教学中的应用效果.方法 本次实验的开展基础数据选择2016年9月—2018年7月进入医院重症医学科实习学生64例,按照学生自身意愿以及学校安排将参与实验学生分为均数相同的两个小组(对照组、观察组),每组实验人数均为32例,其中对照组(n=32)采用传统教学方法 ,观察组(n=32)则应用PBL教学法教学,对比两组学生在学期结束后整体的学习质量情况和教学满意率.结果 观察组学生经过测试后理论知识和专业技能得分均对比对照组更高,教学效果更加理想,观察组学生对于教学的满意率评价更高,P<0.05.结论 重症医学科临床心肺复苏术教学中应用PBL教学法,将理论与实践进行结合,对教学方法 进行改进,全面提升学生的思维理解能力,培养良好的动手能力,促进理论教学与实践的结合,为学生以后的职业生涯提供更加理想的条件.     

AXL表达与乳腺癌预后及临床病理特征关系的Meta分析

目的 探讨受体酪氨酸激酶AXL蛋白的表达对乳腺癌患者预后及临床病理特征的意义。方法 在中国知网(CNKI)、万方医学网(Wanfang Data)、 Cochrane Library、Embase、PubMed和Medline数据库中,搜索国内外公开发表的有关AXL与乳腺癌预后关系的文献,检索时限均为从建库至2019年10月。2位研究者按纳入和排除标准独立筛选文献、提取资料和评价纳入研究的偏倚风险,并进行Meta分析。结果 共纳入7篇文献,包括933例乳腺癌患者。AXL高表达组的乳腺癌患者总生存期(overall survival,OS)明显低于低表达组(HR=2.36,95%CI 1.60~3.46,P<0.000 1),但其表达在无复发生存期(relapse free survival,RFS)和无疾病生存期(disease free survival,DFS)中差异无统计学意义,且与乳腺癌的年龄、临床分期、组织分级、淋巴结转移及受体表达的相关性分析无统计学意义。结论 AXL的阳性表达与乳腺癌患者预后不良有关,是乳腺癌个体化治疗的潜在分子标志物。
