肺炎衣原体抗体效价与多发性硬化的相关性探讨

目的 探讨肺炎衣原体（Chlamydia pneumoniae）感染在多发性硬化（MS）发病和进展中的作用和致病机制。方法 选取急性期MS患者31例，缓解期MS患者28例及其他神经系统疾病患者30例，健康对照者30名，应用酶联免疫吸附试验测定患者和对照者血清及脑脊液中肺炎衣原体IgG和IgM抗体水平。结果 急性期MS组、缓解期MS组、其他神经系统疾病组和健康对照组的肺炎衣原体血清IgG分别为48．4％、35．7％、30．0％、23．3％；4组IgM抗体效价分别为12．9％、14．3％、20．0％、10．0％，总体比较差异无统计学意义（P〉0．05）；急性期MS组与其他神经系统疾病组的脑脊液IgG和IgM抗体效价分别为0、6．7％和0、0，差异无统计学意义（P〉0．05）。结论 肺炎衣原体的感染或重复感染与MS发病相关不紧密，可能仅为MS的伴随感染。     

曲安奈德PLGA微球对兔上腭部创面瘢痕形成影响的实验研究

目的:探讨曲安奈德PLGA微球对创面瘢痕愈合中瘢痕生成的抑制作用,研究局部应用曲安奈德的最佳给药途径。方法:3组共24只兔的上腭部创面模型,分别应用曲安奈德PLGA微球以及曲安奈德悬浊液,在瘢痕形成不同时间后切取瘢痕标本进行HE、VG染色及酶组织化学染色并电镜观察其组织形态学改变来分析曲安奈德不同给药途径的差异。结果:三组兔上腭创面愈合时间不同,表面颜色、质地不一样。电镜、常规染色以及免疫组织化学染色皆说明曲安奈德PLGA微球有明显的瘢痕抑制作用,且效果高于曲安奈德悬浊液。结论:曲安奈德PLGA微球能抑制瘢痕的增殖过程,使瘢痕组织纤维化过程明显减轻。合并手术一次性给药治疗瘢痕有很好的临床价值。     

手术结及打结方法的规范与进展

打结是手术的最基本技术之一，主要包括结扎打结（结扎血管、胆管、淋巴管等）、固定打结（固定引流管、引流条等）及缝合打结。手术不论大小都不能不做许多重复的打结动作，学习手术技术正是从学打结、练打结开始的。由于打结的操作太习以为常，许多手术医生对打结不够重视，对各种手术结并没有一个全面的了解和认识，甚至每日都在重复着不规范的打结操作。手术打结操作是否正确、熟练程度如何等不仅体现了手术医生的基本素质，而且直接关系到手术的效果，甚至关系到病人的安危。     

应用输尿管镜放置双J管早期治疗输尿管阴道瘘

Objective To evaluate the clinical effect of placing double J stent using a ureteroscope in early managing ureterovaginal fistula.Methods Twenty-eight patients cases with ureterovaginal fistula from 2002 to 2008 were treated early with placing double J stent using a ureteroscope and the clinical data were reviewed.Results Twenty-two of 28 cases were treated and double J stent was placed in them by a uretero-scope and 75% (21/28)of cases were cured.Four of 21 cases were treated twice by a ureteroscope and were cured finally.7 cases with failure ureterovaginal treatment underwent ureterocystostomy and were cured.The follow-up from 6 months to 33 months (average 10.1±6.4 months)showed that all of the 28 cases had been cured and had no urinary fistula.Conclusion Placing double J stent using a ureteroscope is the first choice of operative procedure for the early treatment of ureterovaginal fistula.     

血管性勃起功能障碍动物模型的建立

目的探索建立血管性勃起功能障碍(ED)动物模型。方法雄性新西兰大白兔给予胆固醇及高脂饮食,同时用球囊导管损伤双侧髂内动脉内皮。测定术后4周、8周血脂并观察阴茎勃起情况、交配情况,同时用阴茎海绵体注射盐酸罂粟碱、阴茎血管双核素检查、髂内动脉数字减影造影(DSA)等方法研究勃起功能。结果与对照组相比,术后4周、8周模型组动物出现明显高脂血症,勃起程度明显下降,交配实验的各项观察指标均显著降低(P＜0.01),动脉造影显示双侧髂内动脉管腔直径明显缩小,双核素检查动脉显像指数(PIA)及静脉显像指数(PIV)明显降低,但第4周的模型组与对照组PIV结果没有统计学差异(P＞0.05)。结论高脂、高胆固醇饮食同时用球囊导管扩张动物髂内动脉,可以加速模型的形成,从而用于血管性ED的进一步研究。     

特发性颈椎后凸畸形的手术治疗

目的 :明确颈椎前路手术治疗特发性颈椎后凸畸形的可行性和局限性。方法 :本文对 14例颈椎特发性后凸畸形患者采取手术方法进行治疗 ,所有患者均采用颈椎前路椎间盘切除减压 ,椎间隙植骨和前路钢板内固定。结果 :手术后患者临床体征明显改善 ,颈椎后凸畸形由手术前平均 -15 6°矫正为手术后平均 -6 4° ,矫正效果明显 ;手术后患者的短期随访表明颈椎矫正度数在随访中没有丢失。结论 :前路手术 ,延长颈椎前柱能够矫正颈椎的后凸畸形 ,改善临床症状和体征     

EEG source imaging: correlating source locations and extents with electrocorticography and surgical resections in epilepsy patients.

SUMMARY: It is desirable to estimate epileptogenic zones with both location and extent information from noninvasive EEG. In the present study, the authors use a subspace source localization method (FINE), combined with a local thresholding technique, to achieve such tasks. The performance of this method was evaluated in interictal spikes from three pediatric patients with medically intractable partial epilepsy. The thresholded subspace correlation, which is obtained from FINE scanning, is a favorable marker, which implies the extents of current sources associated with epileptic activities. The findings were validated by comparing the results with invasive electrocorticographic (ECoG) recordings of interictal spike activity. The surgical resections in these three patients correlated well with the epileptogenic zones identified from both EEG sources and ECoG potential distributions. The value of the proposed noninvasive technique for estimating epileptiform activity was supported by satisfactory surgery outcomes.     

成年大鼠神经元和星形胶质细胞细胞周期蛋白依赖性激酶抑制因子表达的差异研究

目的比较研究成年大鼠细胞周期蛋白依赖性激酶抑制因子在神经元和星形胶质细胞的表达差异。方法应用免疫荧光和激光扫描共聚焦显微镜观察成年大鼠生理状态下大脑皮层或海马CA1、CA3、DG区神经元和星形胶质细胞细胞周期蛋白依赖性激酶抑制因子(CDKI)p15Ink4b、p21cipl的表达。结果成年大鼠海马区和大脑皮层的神经元有p15Ink4b和p21cipl的表达,细胞核和细胞浆均有表达,且以胞核为主;星形胶质细胞也有上述细胞周期调控蛋白的表达,便细胞数目较少,并且表达这些指标的星形胶质细胞多聚集在海马区。结论成年大鼠大脑皮层和海马区的神经元和星形胶质细胞均表达p15Ink4b和p21cipl,而其在神经元的表达较星形胶质细胞更为普遍。
