了解识别白癜风——访首都医科大学北京右安门医院白癜风治疗中心张淑珍、路淑杰教授

白癜风是一种常见的皮肤病,据有关资料报告,其发病率约占人群的5‰左右。近年来白癜风患者有逐年上升的趋势。对白癜风的发病原因,目前有遗传、精神神经与内分泌、自身免疫、微量元素铜、锌缺乏等方面的学说。白癜风这种皮肤顽症,不但影响患者美丽的容颜,更给广大患者在学习、交友、沟通等方面造成难以逾越的障碍,直接影响患者身心健康。为了让大家正确认识什么是白癜风以及它对学习、交友、沟通及身心健康的危害,特邀请我国知名皮肤病专家张淑珍、路淑杰教授为大家介绍此问题。一、何谓白癜风?张:白癜风是由于皮肤和毛囊内的黑色素细胞内酪…

细胞因子与类风湿关节炎生物治疗

类风湿关节炎（Ｒｈｅｕｍａｔｉｏｄ　Ａｒｔｈｒｉｔｉｓ，ＲＡ）是一种原因不明的自身免疫性疾病，致残率高，严重影响病人的生活质量和预期生命，因此一直是世界范围内研究热．近年来由于分子生物学及免疫学的发展，也使风湿病的研究有了很大进展 大量研究表明，细胞因子在ＲＡ免疫反应中起到了重要作用．由此而产生的细胞因子生物治疗不仅为ＲＡ的治疗开辟了新的途径同时也将成为２１世纪的发展趋势．     

Short Report： Cyclic patterns of incidence rate for skin malignant melanoma： association with heliogeophysical activity

Background: Our previous studies revealed cyclicity in the incidence rate of skin malignant melanoma (SMM; ICD9, Dx: 172) in the Czech Republic (period T=7.50～7.63 years), UK (T=11.00 years) and Bulgaria (T=12.20 years). Incidences com-pared with the sunspot index Rz (lag-period dT= 2, 4, 6, 10 or 12 years) have indicated that maximal rates are most likely to appear on descending slopes of the 11-year solar cycle, i.e., out of phase. We summarized and explored more deeply these cyclic variations and discussed their possible associations with heliogeophysical activity (HGA) components exhibiting similar cyclicity. Methods: Annual incidences of SMM from 5 countries (Czech Republic, UK, Bulgaria, USA and Canada) over various time spans during the years 1964～1992 were analyzed and their correlations with cyclic Rz (sunspot number) and aa (planetary geomagnetic activity) indices were summarized. Periodogram regression analysis with trigonometric approximation and phase-correlation analysis were applied. Results: Previous findings on SMM for the Czech Republic, UK and Bulgaria have been validated, and cyclic patterns have been revealed for USA (T=8.63 years, P<0.05) and Canada (Ontario, T=9.91 years, P<0.10). Also, various 'hypercycles' were established (T=45.5, 42.0, 48.25, 34.5 and 26.5 years, respectively) describing long-term cyclic incidence patterns. The association of SMM for USA and Canada with Rz (dT= 6 and 7 years, respectively) and aa (dT=-10 and 9 years, respectively) was described. Possible interactions of cyclic non-photic influences (UV irradiation, Schumann resonance signal, low-frequency geomagnetic fluctuations) with brain waves absorbance, neuronal calcium dynamics, neuro-endocrine axis modulation, melatonin/serotonin disbalance and skin neuro-immunity impairment as likely causal pathways in melanoma appearance, were also discussed. Conclusion: The above findings on cyclicity and temporal association of SMM with cyclic environmental factors could not only allow for better forecasting models but also lead to a better understanding of melanoma aetiology.
