出土文献与彭祖养生学术研究

彭祖是我国古代的"寿星",随着一系列的考古发现,如汉早期马王堆墓《十问》篇、张家山汉墓《引书》篇,尤其是上海博物馆藏竹简(三)有《彭祖》篇,改变了我们对彭祖学术的认识,不仅为证明楚国产生并流传黄老学派思想提供了佐证,而且在学术史领域提供了新的课题,进一步廓清了彭祖养生学术之源乃是古代巫术,其流是在春秋战国秦汉时期被诸子传诵,与道家等流派结合,具有神仙色彩,最终被汉末魏晋道家改造为神仙方术。     

计算机导航辅助椎弓根螺钉固定的临床研究

目的椎弓根螺钉固定是脊柱病变切除后稳定性重建的标准方法。常规术中透视监测行颈胸节段椎弓根螺钉固定具有相当挑战性,本文旨在就计算机导航辅助椎弓根螺钉固定技术进行初步分析。方法2005年1月至2006年3月在计算机导航系统辅助下,对21例患者（年龄17～63岁,平均43．4岁）共行102枚椎弓根螺钉固定。术前采用0．75mm薄层螺旋CT数据扫描并导入计算机工作站进行脊柱三维重建;术中进行工具注册和匹配后对椎弓根螺钉固定进行实时显示。术后所有病例均采用CT和X线平片随访监测效果。结果手术顺利,螺钉大小选择合适,102枚椎弓根螺钉中100枚螺钉（98%）固定位置及方向准确,2枚椎弓根螺钉突破椎弓根外壁距离小于2mm。所有操作均未发生血管和神经损伤并发症。术中透视次数及手术室人员所受X线辐射量明显减少。结论计算机导航辅助椎弓根螺钉固定是一项安全的手术,且手术精度高。     

Longitudinal Analysis of Severe Acute Respiratory Syndrome (SARS) Coronavirus-Specific Antibody in SARS Patients

The serum antibodies to severe acute respiratory syndrome (SARS) coronavirus of 18 SARS patients were checked at 1 month and every 3 months after disease onset. All of them except one, who missed blood sampling at 1 month, tested positive for the immunoglobulin G (IgG) antibody at 1 month. Fifteen out of 17 tested positive for the IgM antibody at 1 month. The serum IgM antibody of most patients became undetectable within 6 months after the onset of SARS. The IgG antibody of all 17 patients, whose serum was checked 1 year after disease onset, remained positive.

Effect of electro-acupuncture combined with early rehabilitation on motor function and expressions of CD11b/CD18 and tumor necrosis factor-α in patients with acute cerebral infarction

Objective To observe the effect of electro-acupuncture combined with early rehabilitation on the motor function and expressions of the adhesion molecules CD11b and CD18 in the polymorphonuclear leucocytes (PMN) and monocytes and serum tumor necrosis factor-α (TNF-α) levels in patients with acute cerebral infarction (ACI). Methods A total of 165 ACI patients were randomly divided into control group (group A, n=50), conventional rehabilitation group (group B, n=50) and comprehensive rehabilitation group (group C, n=65). The expressions of CD11b and CD18 in the PMN and monocytes and serum TNF-α levels were determined before and at 1, 2, and 4 weeks after the treatment. Thirty-two healthy subjects were also recruited as the normal control group (group N). The neurological function of the subjects was evaluated by modified Edinburgh-Scandinavia stroke scale (MESSS) and Fugi-Meyer Assessment (FMA), and their activity of daily living (ADL) was assessed using Barthel index (BI). Results The CD11b/CD18 expression in the PMN and MN and serum TNF-α level in groups A, B and C were significantly higher than those in group N before and 1 week after the treatment (P<0.05). CD11b/CD18 expression and serum TNF-α level were significantly lower in groups B and C than in the group A at 1 week after the treatment, and significantly lower in group C than in group B (P<0.05). At 2 weeks of treatment, CD11b/CD18 and TNF-α were significantly lower in groups B and C than in the group A, being the lowest in group C (P<0.05). The scores of mESSS in both groups B and C were lower than that in group A, and the scores were lower in group C than in group B. Group C showed higher FMA scores than group B, both having higher scores than group A. At 4 weeks of treatment, the mESSS scores were significantly lower, hut the FMA and ADL score significantly higher in groups B and C than in the control group (P<0.05), and the differences were more obvious in group C. Groups B and C had greater effective rate than group A (P<0.05), and the rate was the highest in group C (P<0.05). Conclusion Electro-acupuncture combined with early rehabilitation promotes the recovery of motor function in ACI patients probably by regulating the expressions of the adhesion molecules CD11b and CD18 on the PMN and monocytes and the serum levels of TNF-α.

The role of endotoxin in the pathogenesis of experimental multiple system organ failure: a preliminary report.

In this study, an animal model of multiple system organ failure (MSOF) in rabbits, engendered by feeding E. coli prior to severe hemorrhagic shock, was used for the purpose of investigating 1) the relationship between lipopolysaccharide (LPS) and MSOF, and 2) the effectiveness of Re-LPS antiserum in preventing MSOF. The results showed that endotoxemia occurred very early, and its degree correlated well with that of organ dysfunction. Re-LPS antiserum administration abated the toxic effects and lowered the incidence of MSOF. These results suggest that sequential analysis of circulating LPS levels may be useful for the early diagnosis of MSOF, and that gut-derived endotoxin might play an important role in the pathogenesis of experimental MSOF.     

自由基损伤和β2糖蛋白1在自身免疫疾病中的作用

目的 研究被自由基氧化修饰的β2糖蛋白1(β2GPl)在自身免疫疾病中自身抗体产生中的作用。方法 采用高氯酸沉淀，两步肝素连接的交联琼脂糖凝胶层析结合葡聚糖凝胶G—100分离纯化大鼠β2GP1；应用自由基氧化修饰大鼠β2GP1；氧化修饰的β2GP1(oxβ2GPl)、β2GPl分别加与不加心磷脂(CL)及CL免疫大鼠，ELISA方法检测免疫大鼠血清中抗β2GP1抗体和抗心磷脂抗体(ACA)。结果 两步亲和层析结合凝胶过滤层析有效地分离纯化了大鼠β2GPl，蛋白纯度达90．78％；通过碳基含量测定证实了自由基对β2GP1的氧化修饰；oxβ2GGP1加CL、β2GP1加CL、oxβ2GPl免疫组与空白对照组、实验对照组比较ACA水平有显著升高(P＜0.001)，oxβ2GP1加CL免疫组与β2GPl加CL免疫组比较ACA水平差异有显著性(P＜0.05)；oxβ2GP1免疫组与oxβ2GPl加CL免疫组比较ACA水平差异不显著(P＞0.05)；oxβ2GPl加CL、oxβ2GPl免疫组与对照组比较，抗oxβ2GP1抗体水平有显著升高(P＜0.05)。结论 两步肝素连接的交联琼脂糖凝胶层析结合葡聚糖凝胶G—100能有效地分离纯化β2GPl；oxβ2GPl诱导了ACA和抗oxβ2GPl抗体的产生；β2GPl可能是自身免疫疾病发生过程重要的辅助因子或靶抗原，而自由基对β2GP1损伤可能是自身免疫疾病发病机制中的一个重要病理过程。
