超声及临床特征对附睾局灶性病变的鉴别价值

目的:评价超声及临床特征在附睾局灶性病变鉴别诊断中的应用价值。方法:回顾性分析附睾局灶性病变48例,包括非特异性附睾炎、附睾结核和附睾精液囊肿。分析附睾局灶性病变大小、形态、位置、回声强度及均一性,鞘膜腔是否有积液;病灶血流的程度以及患者年龄、病程和阴囊压痛程度。结果:附睾结核病灶平均面积比非特异性附睾炎病灶大(P<0.05),并多可见钙化斑。非特异性附睾炎病灶的血流信号比附睾结核(P<0.05)及附睾精液囊肿(P<0.01)丰富;非特异性附睾炎病程比附睾结核(P<0.01)和附睾精液囊肿(P<0.01)短;非特异性附睾炎病灶的压痛比附睾结核(P<0.01)和附睾精液囊肿(P<0.01)明显。附睾局灶性病变发生位置及有无鞘膜积液无明显区别(P>0.05)。结论:超声和临床特征对附睾局灶性病变鉴别诊断具有重要的价值,为临床诊断、治疗附睾疾病及评价疗效提供客观依据。     

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.     

AngⅡ1型受体拮抗剂与动脉粥样硬化斑块稳定性的关系

近年来,人们越来越关注A ngⅡ在动脉粥祥硬化形成的病理上所扮演的重要角色,同样,它在不稳定斑块的形成中也起着重要作用。A ngⅡ1型受体拮抗剂通过抑制炎症、保护内皮、减少血流剪切力等作用起到稳定斑块的作用。     

针灸划刺法快速止痛治疗老年带状疱疹79例

带状疱疹是由水痘-带状疱疹病毒引起的机体单侧性、丘疱疹性伴有神经痛的急性神经性皮肤病.由于老年人机体抵抗力越来越差,加上各种疾病、劳累、精神、创伤、生活环境的改变等诸多因素的影响,故易患带状疱疹,而且疱疹数量多、面积大、疼痛程度重.

胰岛素受体基因多态性与脑梗死关系的研究进展

胰岛素通过与靶细胞膜上的特异受体结合发挥其生理作用，它的结构与功能决定了胰岛素对细胞的作用。胰岛素受体基因多态性是胰岛素抵抗（IR）的重要原因之一。胰岛素受体（INSR）异常引起的血糖代谢紊乱和胰岛素抵抗可导致动脉粥样硬化（AS）、高血压及微动脉损害，因而胰岛素受体基因多态性可能参与脑梗死的发生与发展。本文就胰岛索受体基因多态性与脑梗死的相互关系做一综述。     

糖皮质激素减少猪脑死亡后心功能障碍的发生

器官移植供体大约半数来自于创伤性脑损伤及继发脑死亡（BD）患者，而其中只有33％的心脏适于移植。脑死亡后多种病理改变能导致心功能障碍而不适于移植。为了减少脑死亡相关的心功能障碍，目前措施是应用甲基泼尼松龙、甲状腺激素及抗利尿激素联合复苏法，但临床效果存在争议。最近美国科研人员对单独应用糖皮质激素对猪脑死亡后心功能障碍的保护作用进行了研究。他们将杂种猪进行硬膜下气囊扩张造成脑损伤，通过检测脑灌注压及激光多普勒血流确认脑死亡，     

G蛋白耦联受体激酶结合蛋白1通过调节细胞外调节激酶1/2的活性促进成骨细胞迁移

目的探索G蛋白耦联受体激酶结合蛋白1(GITI)在成骨细胞迁移中的作用,并分析其机理。方法通过Western blot方法检测GIT1蛋白在鼠的成骨细胞内的表达；用免疫荧光染色方法确定：在血小板衍生生长因子(PDGF)不刺激和刺激的条件下,GIT1和细胞外调节激酶1/2(ERK1/2)在成骨细胞内的位置；用共同免疫沉淀的方法测定GIT1和ERK1/2相互结合,并且用免疫荧光双染的方法确定这两种蛋白相互结合的位置；用包含GIT1-RNA发夹结构的腺病毒感染成骨细胞后,用免疫荧光染色方法确定磷酸化ERK1/2(pERK1/2)在成骨细胞内的位置,用划痕愈合法检测在PDGF刺激下的迁移能力。结果在成骨细胞内,PDGF刺激导致了GIT1和ERK1/2的相互结合,并且这种结合发生在成骨细胞的局部粘附内。包含GIT1-RNA发夹结构的腺病毒明显抑制了pERK1/2招募至成骨细胞局部粘附内以及PDGF所刺激的成骨细胞的迁移。结论在PDGF刺激下,GIT1招募pERK1/2至成骨细胞的局部粘附内,从而促进成骨细胞的迁移。
