糖尿病肾病内热证与肾功能及炎症因子的相关性研究

目的:观察糖尿病肾病不同分期内热证与肾功能及炎症指标的相关性。方法:收集202例糖尿病肾病患者的临床资料,采用酶联免疫吸附法检测微炎症指标,包括超敏C反应蛋白(high-sensitivity C-reactive protein,HS-CRP)、白细胞介素-6(interleukin-6,IL-6)、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α),进行统计分析。结果:与非内热证组比较,中期、晚期内热证组24小时尿蛋白定量明显升高;晚期内热证组的血清肌酐明显升高,肾小球滤过率(glomerular filtration rate,GFR)明显降低;炎症因子CRP、IL-6、TNF-α随疾病进展均呈上升趋势;晚期内热证组与非内热证组比较,IL-6、TNF-α升高;中期HS-CRP与内热积分呈正相关,晚期TNF-α与内热积分呈正相关。结论:内热病机贯穿于糖尿病肾病的始终,与糖尿病肾病肾功能以及疾病进展密切相关;同时,内热积分与炎症因子HS-CRP、TNF-α的表达存在一定的相关性,这种相关性在疾病中期、晚期表现更加明显。     

Guillain-Barré syndrome in South-West Stockholm, 1973–1991, 3. Clinicoepidemiological subgroups

Using hierarchical cluster analysis, applied to 47 cases of Guillain-Barre Syndrome (GBS) incident in South-West Stockholm (SWS) during the period from January 1973 to June 1992, we identified three major clinicoepidemiological subgroups. The first subgroup, 25.5% of the cases (26.7 ± 6.7 years), recorded a peak incidence at ages 20–29 years and presented significant differences from other subgroups, a high proportion of cases with onset at low age preceded by respiratory infection (83.3%) and with normal motor conduction velocity (50.0%). Also found, were less affected biological parameters, a rapidly progressive course and independence in gait at one month after onset. A second subgroup, 27.7% of cases, was severely affected, clinically and functionally. It consisted predominantly of young individuals (22.7 ± 11.1 years), with a high incidence (69.2% of cases) in autumn. A third subgroup, comprising 40.47; of cases, was older (61.1 ± 11.0 years) and, in general, also severely affected. The incidence of this form appeared to be invariant with time.     

335例术后全身炎症反应综合征的临床分析

【目的】了解手术创伤对术后全身炎症反应综合征 (SIRS)的影响。【方法】搜集外科重症监护室 (SICU) 335例患者的术后资料 ,分析不同手术组SIRS发病率 ;手术时间、失血量与SIRS持续时间的关系 ;SIRS持续时间与术后并发症的关系。【结果】术后SIRS发病率为 75 8% ,大手术高达 92 4 % ;无并发症患者失血量与SIRS持续时间呈正相关 (r1=0 783,P<0 0 1) ,手术时间与SIRS持续时间呈正相关 (r2 =0 398,P <0 0 1) ;随着SIRS持续时间延长 ,并发症发病率显著增高 (P<0 0 5 )。【结论】术后SIRS发生、发展与手术创伤密切相关 ;监测SIRS进程有助于及早发现并发症     

Idiopathic Spinal Cord Herniation as a Treatable Cause of Progressive Brown-Sequard Syndrome

Idiopathic spinal cord herniation is a rare spinal cord disorder caused by spinal cord prolapse through a adural defect. It is a curable disease, so early detection is of particular importance. We report a 38-year-old woman with Brown-Sequard syndrome which was caused by the thoracic spinal cord herniation. Her weakness was almost completely resolved after surgical management, which emphasizes the importance of early diagnosis and surgical management in this rare disease entity.     

特发性脊柱侧凸患者椎旁肌中神经营养素3的表达及意义

目的:研究特发性脊柱侧凸(IS)患者椎旁肌组织中神经营养素3(Neurotrophin-3,NT-3)在核酸水平(mRNA)的表达情况。方法:随机选择19例IS患者,年龄12～19岁,平均14.3岁,Cobb角42°～80°(平均54°)。手术中取顶椎(T7～T10)凸侧、凹侧椎旁肌肉组织,采用半定量RT-PCR法检测NT-3 mRNA表达水平。取4例相同年龄段的椎间盘突出患者手术切口头端非病变部位椎旁肌肉组织作为对照。结果:对照组椎旁肌中NT-3的mRNA表达阳性率50%,相对表达量为0.0237±0.0158,IS组患者椎旁肌中表达阳性率63.16%,相对表达量为0.1213±0.0939,较对照组表达量增加(P=0.051)。9例Cobb角>50°的IS患者表达阳性率为44.44%,相对表达量0.0431±0.0359,和对照组无明显差异;10例Cobb角≤50°的IS患者中表达阳性率为80%,相对表达量为0.1604±0.0895,与对照组和Cobb角>50°的IS患者比较有明显增加(P<0.01)。结论:正常椎旁肌组织中NT-3在核酸水平微量表达,特发性脊柱侧凸患者椎旁肌组织中NT-3 mRNA表达增加,尤其在小角度IS患者中增加明显,提示IS患者中存在神经营养因子表达异常。     

Structural vertebral changes in the horizontal plane in idiopathic scoliosis and the long-term corrective effect of spine instrumentation

Summary The rotation and structural changes of the apex vertebra in the horizontal plane as well as of the thoracic cage deformity were quantified by measurements on computed tomography (CT) scans from patients with right convex thoracic idiopathic scoliosis (IS). The CT scans were obtained from 12 patients with moderate scoliosis (mean Cobb angle 25.8°, r 13°–30°) and from 33 with severe scoliosis (mean Cobb angle 46.2°, r 35°–71°). In addition, CT scans of thoracic vertebrae from 15 patients without scoliosis were used as reference material. Ten of the scoliotic cases had had Cotrel-Dubousset instrumentation (CDI) and posterior fusion and had entered a longitudinal study on the effect of operative correction on the re-modelling of the apical vertebra. An increasingly asymmetrical vertebral body, transverse process angle, pedicle width and canal width were found in the groups with scoliosis as compared with the reference material. Vertebral rotation and rib hump index were significantly larger in patients with early and advanced scoliosis than in normal subjects. The modelling angle of the vertebral body, the transverse process angle index and the vertebral rotation in relation to the middle axis of the thoracic cage were significantly greater in patients with severe than with moderate scoliosis. The results of this longitudinal study suggest that the structural changes of the apical vertebra regress 2 years or more after CD instrumentation.     

蝮蛇抗栓酶与肝素抗凝治疗小儿肾病的疗效比较
