研究血液及其有形成分流动与变形规律的部分称为血液流变学,目前血液流变学在恶性肿瘤检测中的应用日益受到重视。一般认为恶性肿瘤患者存在血液高粘、高凝、血细胞高聚状态,血液流变学异常可能会促进肿瘤的发生和发展。研究恶性肿瘤血液流变学指标的变化可为当前防治恶性肿瘤提供一条新途径。我们对不同恶性肿瘤中血液流变学指标变化的研究状况进行综述。 相似文献

The aging of the American population has significantly changed medical practice over the last century. As is well known, life expectancy first began to increase dramatically in the late 19th century, but at the same time that the numbers of older people have been increasing, the social and cultural meanings of growing old have also changed. It is likely that different cohorts of older people have had different experiences with old age because of the time periods they lived through. This paper offers one way to look at some of the historical changes that have affected the public and the medical profession on the subject of old age by looking at old age through American popular literature in the first half of the 20th century in three overlapping time periods. In the first three decades of the century, the concept of old age was widely defined, and older people (rather than physicians) were the principal authorities in describing the qualities of old age. In the third and fourth decades of the century, the idea of old age was starting to acquire increasing negative connotations, but chronological age itself did not signal the beginning of old age. However, by the late 1930s and 1940s, old age became widely viewed as a specific social and medical problem to be addressed by professionals, and older people had become a recognizable population, with a variety of groups organized around their care. This paper illustrates changes in American understandings of old age within and without the medical profession and suggests ways in which popular conceptions of old age might continue to shift and affect how physicians take care of their older patients in the future. 相似文献

OBJECTIVES: To assess the prevalence of tuberculous infection and active tuberculosis (TB) in old age homes in Hong Kong and to determine whether there is institutional transmission in these homes. DESIGN: Cross-sectional. SETTING: Old age homes. PARTICIPANTS: Total of 2,243 residents, representing 84.6% of all residents in 15 old age homes; 1,698 were women, and 545 were men, with an average age of 82. MEASUREMENTS: All residents had a questionnaire-based interview, medical record review, two-stage tuberculin testing using two units purified protein derivative-RT23, and a chest x-ray. Those with radiological abnormalities had sputum examined for acid-fast bacilli. RESULTS: The estimated prevalence rate of active TB in this population was 669 per 100,000, significantly higher in men than in women (1,101 per 100,000 vs 530 per 100,000). The proportion with positive tuberculin reactivity (> or =10 mm induration) after two-stage testing was 68.6%, significantly higher in men than in women. There was no evidence of active transmission of disease in these old age homes, with restriction fragment length polymorphism (RFLP) analysis performed on five cases of active pulmonary TB in the home with the highest rate of TB showing unique RFLP patterns. CONCLUSION: The rate of active TB and TB infection in old age homes in Hong Kong is still high. Because treatment for latent TB carries a high risk for liver dysfunction in this population, clinicians and other healthcare workers need a high index of suspicion and to diagnose and treat this disease as early as possible to prevent transmission. 相似文献

AIMS: To take appropriate account of duration of follow-up in estimating age-specific associations of 'usual' blood pressure and cholesterol with death from coronary heart disease. METHODS and RESULTS: Blood pressure and cholesterol were measured in 18 841 men at entry to the Whitehall study, and coronary heart disease mortality was recorded during a 26-year period. Biennial re-measurements of these risk factors in the Framingham study were used to obtain period-specific corrections for 'regression dilution'. For coronary heart disease deaths at ages 40-64, 65-74 and 75+ years in the Whitehall study, the mean times since baseline were 9, 15, and 21 years, respectively. In uncorrected analyses of coronary heart disease risk in each age range, a 10 mmHg lower systolic blood pressure at baseline was associated with proportional risk reductions of only 19%, 14% and 10%, respectively (P<0.001 for trend with age). After period-specific correction for regression dilution, a 10 mmHg lower usual systolic blood pressure about 5 years before coronary heart disease death was associated with risk reductions of 25%, 23% and 21%, respectively (trend P=0.1). Similarly, a 1 mmol . l(-1)lower blood cholesterol was associated with proportional reductions in coronary heart disease risk of 21%, 17% and 11% (trend P<0.001) in uncorrected analyses, by contrast with proportional reductions of 27%, 26% and 21% (trend P=0.5) after period-specific correction. CONCLUSIONS: After making appropriate allowance for the longer interval between baseline measurements and death at older ages, reductions in the risk of coronary heart disease death associated with differences in usual levels of blood pressure or cholesterol at some particular fixed time prior to death were about as great in old age as in middle age. 相似文献
