腰椎间盘突出症并神经根管狭窄的治疗

目的：探讨腰椎间盘突出症合并神经根管狭窄的临床诊断和手术治疗。方法：对1996-1999年间,因腰椎间盘突出症合并神经根管狭窄38例行手术治疗,术中均行神经根管探查并彻底松解受压神经根。结果：术后随访38例,优20例,良15例,一般2例,差1例,优良率92.11%。结论：神经根管扩大和神经根探查彻底减压是手术成功的关键。     

视神经管减压术治疗视神经挫伤20例分析

目的：报告视神经挫伤行视神经管减压术的治疗效果。方法：手术治疗限定于外伤后不超过1月且无严重颅脑损伤及无严重全身疾病者。采用局麻筛蝶窦入口法,手术前后常规用糖皮质激素及神经生长因子。结果：20例术前无光感16例,术后1周视力有光感及手动以上12例,占75％;术前视力在手动－0．04以内4例,术后视力均提高。术后随访3个月除2例外视力均有提高,最好达到0．3。结论：视神经挫伤病期不超过1月虽视力已无光感也不应放弃行视神经管减压术。

Liposomal Bupivacaine vs Ropivacaine for Adductor Canal Blocks in Total Knee Arthroplasty: A Prospective Randomized Trial

BackgroundThe purpose of this study is to determine the benefit of the analgesic liposomal bupivacaine compared to ropivacaine, by assessing pain and joint stiffness, and total oral opioid consumption by milligram morphine equivalent (MME) after total knee arthroplasty.MethodsPatients were randomized to receive either the study drug (liposomal bupivacaine admixed with bupivacaine) or the control drug (ropivacaine) in an adductor canal block. Only the anesthesiologist performing the block was aware of which arm of the study the patient was randomized to. MME, pain, Knee injury and Osteoarthritis Outcome Score Joint Replacement, and overall benefit of analgesia scores were recorded 24, 48, and 72 hours post-surgery either face-to-face or via telephone depending on patient discharge status.ResultsOne hundred patients were enrolled into the study and analyzed: 54 in the control group and 46 in the experimental group. Primary outcomes measured were pain as a numerical rating scale, MME, and length of stay in hours. Secondary outcomes were joint pain and stiffness recorded as Knee injury and Osteoarthritis Outcome Score Joint Replacement outcome and overall benefit of analgesia score. No statistically significant between-group differences were observed for any measured outcome.ConclusionWe did not find any supporting evidence that liposomal bupivacaine yields increased pain relief following total knee arthroplasty compared to the control drug, ropivacaine.     

国人男性椎管的测量与观察

本文对广西出土的113例男性干燥椎骨的椎孔,进行了矢径、横径的测量和形态观察。椎孔的矢、横径在壮族(30例),汉族(57例)间无显著差异(P>0.05)。在C_(3～6)椎骨水平,推管的矢径和形态与脊髓的外形不一致,矢径于该处形成生理性狭窄,以C_4处为最小(12.92mm)。除C_1外,椎管的形态可分为4型:Ⅰ型圆型;Ⅱ型三角型;Ⅲ型过渡型;Ⅳ型不整型。 C_(1,2)椎管的形状为圆型,向下至C_6,通过半圆形逐步过渡到三角形(C_6占81.31％);再向下至T_6,三角形通过蛤形和多边形又逐渐过渡为圆形(T_6占84.76％);再向下至L_5,又通过蛤形逐渐过渡为三角型(L_5占99％)。从L_3至L_5,三角形椎孔有逐步通过钟形向三叶形过渡的趋势。三叶形腰椎管占5.02％。本文结果支持Eisenstein的观点,认为三叶形结构是一种普通的、非病理性的现象,与年龄增长、骨赘或椎孔狭窄无关,这或许是一种正常的发育性变异。     

神经营养素-3重组腺病毒促进脊髓背根神经节的存活

目的：观察神经营养素－3（neruotrophin3,NT－3)重组腺病毒（adorsal root ganglia ,DRG）细胞存活的促进作用,方法：原代培养DRG,加入不同感染增殖率（multiplicity of infection,MOI)的Ad-NT-3,观察DRG细胞的形态,MTT法测定DRG细胞的增殖活性,结果：当加入MOI为10和50的Ad-NT－3时,形态学发现,DRG细胞数目增加,突起变长,尤其以3d后表现更为明显,DRG细胞的增殖活性显增加（P＜0．01）,当MOI为100时1d和3d,DRG细胞数目明显减少,无突起或变短,部分细胞死亡,MTT法测定DRG细胞的增殖活性均显降低（P＜0．01）,结论：NT－3基因能通过腺病毒介导表达NT－3蛋白,促进体外培养DRG细胞的生活。
