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.     

养阴健脾法临床应用举隅

养阴健脾法系治疗脾阴不足证的一大法则，用于临床常获奇效。现仅援引验案几则介绍如下。     

牙冠延长术在残根残冠修复中的临床疗效

目的评价牙冠延长术在牙体缺损达龈下的残根残冠修复中的临床疗效。方法自2004年5月至2005年6月,对32例患者的36颗牙体缺损达龈下的患牙,术前按断端位于龈下最深距离分为A组(20颗患牙,距离<3.0mm)和B组(16颗患牙,3.0mm≤距离≤4.0mm),均采用牙冠延长术暴露龈下牙体断面,术后6周行桩冠修复。分别记录和比较手术前、后牙周探诊深度(PD)、菌斑指数(PLI)、龈沟出血指数(SBI)和牙齿松动度,以观察临床疗效。结果术后随访患者6个月,两组病例术后6周牙体断端均暴露较好、龈缘颜色正常,术后修复效果有效率为100%,满意率为77.78%。A组术后无松动,修复效果满意;B组术后50.00%出现Ⅰ度松动,修复效果欠佳,两组修复效果比较差异有显著意义(P<0.05)。术后各阶段两组的PD、PLI、SBI均明显优于术前(P<0.05),但两组术后牙周指数比较差异无显著意义(P>0.05)。结论牙冠延长术有利于残根残冠的保存和修复,但要注意适应证的选择。     

细胞间黏附分子-1在实验性自身免疫性脑脊髓炎大鼠中表达的动态变化及作用

目的探讨细胞间黏附分子-1(ICAM-1)在实验性自身免疫性脑脊髓炎(EAE)大鼠中表达的动态变化及其作用。方法分别取免疫后第4、6、8、10、12、14、16、18、20天EAE大鼠脑和脊髓制成石蜡切片,行HE染色和ICAM-1半定量免疫组化分析。结果免疫后第8天ICAM-1表达即出现明显上调,早于临床症状的发生;随免疫后时间的延长,ICAM-1表达呈逐渐增高后缓慢下降的变化趋势,并且与EAE大鼠病情评分呈显著正相关(r=0.57,P=0.003)。结论ICAM-1的表达上调可能在EAE发病中具重要作用。     

学习困难儿童智力及记忆力特征分析

目的探讨学习困难儿童的智力、记忆力特征。方法学习困难(LD)根据ICD-10五条诊断标准,精神发育迟滞(MR)根据国际疾病分类第10版(ICD-10)诊断标准,分为实验组LD组;对照组a.正常组,b.弱智组。采用中国韦氏儿童智力量表进行智力测验,记忆力测验采用中国科学研究院编制的临床记忆量表。结果LD组与正常对照组在语言智商、操作智商、总智商[(86.23±10.65)分,(87.44±12.59)分,(84.09±13.96)分vs(102.27±10.21)分,(103.22±11.65)分,(103.28±9.88)分]及分测验值差异均有显著性(P<0.01);LD组儿童VIQ与PIQ相距一个标准差以上的比率明显高于对照组(2=9.29,P<0.01),也较MR对照组多(2=4.29,P<0.05)。LD组记忆商(MQ)明显低于正常对照组(P<0.01)。结论LD儿童智商、记忆商水平低于正常儿童,且存在明显智力结构发展不平衡。     

围术期糖尿病与心血管病相关性研究及处理进展

糖尿病是心血管病重要的独立高危因素。糖尿病增加心肌缺血损伤的危险性，引起心肌本身和心肌内小血管病变，抑制心肌缺血预处理的作用。现就糖尿病对心血管病的影响及糖尿病病人围术期的处理进展作一综述。     

有限内固定结合外固定支架治疗胫骨远端骨折

目的探讨有限内固定结合Hybrid外固定支架治疗胫骨远端骨折的疗效。方法从2003年1月～2005年7月,使用Hybird外固定支架治疗胫骨远端骨折21例,按AO分类:A1型4例;A2型5例;A3型4例;C1型2例;C2型3例;C3型3例,其中开放性骨折8例,手术采用有限切开,骨片钉固定,Hybrid外固定支架不跨踝关节固定。结果术后21例均获随访,平均随访时间12.3个月,骨折平均愈合时间7.6个月。功能评定采用Bone的踝关节活动度进行评价,优良率达76%。结论Hybrid外固定支架设计合理并能维持骨干的轴线,骨片钉能很好的固定骨折块,同时避免了软组织的并发症,可使踝关节早期活动,防止踝关节僵硬,因而是治疗胫骨远端骨折有效的方法之一。
