改革开放以来,随着城市化和工业化的进程不断加快,农民工已经与我国的经济发展和社会主义现代化建设息息相关。然而,目前我国农民工的受教育程度普遍较低,其文化水平、工作技能以及自身的素质都远远跟不上现代化建设的需要。因此,农民工的教育培训问题受到政府及社会各界人士的广泛关注和重视。不少专家学者都从不同角度对农民工教育培训问题进行了研究和探讨,并取得了许多很有价值的研究成果。本文根据时间跨度,从20世纪80年代初至亚洲金融危机、1999年至2008年新的金融危机、2008年金融危机至今这三个阶段归纳总结了我国农民工教育培训的研究现状,并给出了评价及建议。 相似文献

There may be a great potential in the use of diagnostic "markers" of osteoarthritis in synovial fluid to diagnose the disease in an earlier stage and perhaps assess the severity of the disease and monitor the effect of a treatment. In the present study, potential markers are characterized, discussed, and grouped according to the latest knowledge on the etiology, pathogenesis, and pathology of osteoarthritis. They are grouped according to their origin as either cartilage degradation products, or related to the mechanisms of cartilage degradation, or related to chron-drocytic anabolic activity during disease, or related to genetic disorders. Also potential markers that have not yet been studied clinically or experimentally are discussed. Examples of the progress that has been made in human medicine approaching reliable diagnostic markers that should also be tried in veterinary medicine are described. 相似文献

Accumulating evidence suggests that epileptic seizures originating from the temporal lobe (TL) occur in cats. Typically, affected animals have clinically focal seizures with orofacial automatisms including salivation, facial twitching, lip smacking, chewing, licking, and swallowing. Motor arrest and autonomic and behavioral signs also may occur. Many affected cats have magnetic resonance imaging (MRI) changes within the hippocampus or histopathologically confirmed hippocampal sclerosis or necrosis. From the 1950s to the 1980s, cats frequently were used as animal models for neurophysiological experiments and electrophysiological studies, from which important basic knowledge about epilepsy originated, but which has been rarely cited in clinical veterinary studies. These studies were reviewed. Experimental research on cats showed the widespread anatomical connections among TL structures. The ictal clinical signs originating from the hippocampus, amygdala, or lateral temporal cortex are similar, because of their dense interconnections. The ictal signs can be divided into autonomic, somatic, and behavioral. For research purposes, a 6‐stage system was established, reflecting the usual sequential progression from focal to generalized seizure: attention response (1), arrest (2), salivation, licking (3), facial twitching (4), head turning or nodding (5), and generalized clonic convulsions (6). Knowledge of this data may help in recognizing low‐stage (stage 1 or stage 2) epileptic seizures in clinical practice. Early experimental research data are in accordance with recent clinical observations regarding ictal clinical signs of TL epileptic seizures in cats. Furthermore, the research data supports the idea that TL epilepsy represents a unique clinical entity with a specific seizure type and origin in cats. 相似文献

Diagnosis of Disseminated Intravascular coagulation (DIC) is controversial in both human and veterinary medicine. This article reviews the available literature in human and veterinary medicine regarding the etiology, pathophysiology, and diagnosis of DIC with emphasis on the diagnosis of DIC in dogs. Controversy surrounding the diagnosis of DIC arises from the complex nature of the disease itself, in addition to the absence of a consensus strategy for laboratory testing. The available literature indicates that dogs diagnosed with DIC possessed various hemostatic function testing abnormalities, typically possessed an underlying disease that predisposed to DIC, but may or may not have had clinically identifiable hemorrhage or thrombosis. Additionally, the hemostatic function testing utilized in diagnosis is not uniform. Generalizations about the usefulness of individual assays or diagnostic strategies cannot be formulated because of the marked diversity of the types of cases studied, as well as the small number of cases reported in the literature.
