Association between intervertebral disc degeneration and disturbances of blood supply to the vertebrae 总被引:1,自引:0,他引:1
Low back pain is a common public health problem in western industrialized societies and the world as well.Studies indicate that the prevalence rate ranges to 35%, with around 10% of patients from 12% becoming chronically disabled. It also places an enormous economic burden on society. Although the exact cause of low back pain has yet to be defined, intervertebral disc degeneration is considered a major source of it. Since patients with degenerative discs are often asymptomatic, the mechanisms of it are still unclear. 相似文献

Epistaxis remains one of the most common otolaryngology emergencies. Severe epistaxis may be caused by internal carotid artery (ICA) pseudoaneurysm or cavernous fistula, which is clinically rare but life threatening if it is not diagnosed and treated timely. Most ICA pseudoaneurysms are mainly caused by trauma with few other causes. From January 1998 to December 2005, a total of 8 cases with non-traumatic carotid artery pseudoaneurysm were correctly diagnosed through digital subtraction angiography (DSA) in Ganzhou People's Hospital. The patients had suffered from serious nose bleeding repeatedly and had been resistant to routine treatments. 相似文献

Multifocal motor neuropathy (MMN) is a rare,.focal,inflammatory,demyelinating disease of the peripheral nerves with pure motor involvementJ MMN is clinically characterized by slowly progressive,asymmetric,distal,upper limb predominant weakness,in the absence of sensory disturbances) Weakness is usually multifocal and connected to a distinct motor nerve,such as the musculocutaneous nerve resulting in biceps weakness,the posterior interosseus nerve resulting in finger drop,the median,ulnar,or radial nerve resulting in dexterity problems or grip weakness,or the peroneal nerve resulting in a foot drop.Onset of clinical manifestations is between 20 and 50 years of age.The prevalence of MMN is reported as 1-2 per 100 000.2 MMN is three times more frequent in men as compared to women. 相似文献

“针刺临床试验干预措施报告的标准”(STandardsfor Reporting Interventions in Clinical Trials ofAcupuncture,STRICTA)为作者报告针刺临床试验提供指南。STRICTA旨在帮助临床试验的作者明晰地报告针刺临床试验中所提供的治疗的特定组成部分。我们需要从已发表的试验报告中得到有关干预措施的完整、准确而又透明的信息,从而更好地解释并严格评价其研究结果。CONSORT(Consolidated Standards of ReportingTrials,临床试验报告的统一标准)工作组已着手应对发表的临床试验报告质量低下的问题。CONSORT声明于1996年首次发表[1],之后于2001年[2]和2010年[3]作了修订,该声明为提高平行对照随机临床试验的报告质量制定了指南。最近的修订版即CONSORT2010,包括一份含25项条目的对照检查清单和一张流程图,以及对全部条目的解释和良好报告的实例[3,4]。清单中的条目5涉及干预措施的报告质量。在西医领域中,临床试验干预措施的报告存在诸多问题并已引起注意。有一项研究对这类临床试验报告作了仔细审读,发现... 相似文献

Objective To investigate the effect of iron on the growth, physiology and photosynthesis of cyanobacteria. Methods A gradient of iron concentrations was employed to investigate the growth, photo-pigments (chlorophyll A and phycocyanin), and cell chemical contents (C, N, P) of Microcystis aeruginosa in response to different iron additions. Results The specific growth rate during the exponential growth phase, as well as the cell chlorophyll A and the phycocyanin content, was limited by iron below 12.3μmol Fe.L^-1. The growth was inhibited when the iron concentration was at 24.6 μmol Fe.L^-1. The cell chlorophyll A and the phycocyanin content were saturated when the iron concentration was above 12.3μmol Fe.L^-1 and declined slightly at 24.6 μmol Fe.L^-1. At a low iron concentration (about 6.15 μmol Fe-L^-1 and less), the cell nitrogen and carbohydrate content were iron limited, and the variation of the cell phosphorus content was similar to that of the nitrogen and carbohydrate, with a transition point of 12.3 μmol Fe.L^-1. Conclusion The variation ofcynobacteria growth is synchronous with that of the photo-pigments or the cell chemical content, and there exist relationships among photosynthesis, growth and internal chemical content, which could be useful for the growth estimation from the cell characteristics. 相似文献

非条件logistic回归分析方法的主要算法是采用最大似然法对参数进行估计。最大似然法在大样本前提下进行参数估计是非常有效的,但当处理样本量小的数据,特别是按多个定性变量进行分层且每一层中样本量很小时, 相似文献
