吸烟致癌,这是人人皆知的事实.对于吸烟致癌,随时间的推移认识越来越深入.吸烟不仅可致肺癌、鼻咽癌、喉癌、膀胱癌和胰腺癌,国际癌症研究协会(IARC)报告指出,烟雾中的4000多种有害物质可通过肺泡吸收,还引起或有助引起一些不常与烟草有联系的癌,这些癌包括宫颈、肝、胃、肾和鼻窦,还有髓样白血病. 相似文献

写给读者的话:我们听到了一些朋友对我们登在第一期的文章的反馈.谢谢大家的关注.我想特别强调一点,我写这一组文章的意图,是想表达作为患者和家属,我们要理智地面对疾病,了解它,研究它,积极地参与和配合医生的诊断治疗决策和实施.眼下,社会上对于医院和医生的妖魔化倾向严重,医患关系成为一个非常敏感的问题,我们看到许多对于医生的指控是以偏概全不符合事实的. 相似文献

Objective: To detect the expression of GAS7 in osteosarcoma and discuss its significance. Methods: Immunohistochemistry SABC method was applied to detect GAS7 expression in specimens of 54 osteosarcoma and 15 osteochondroma cases. Results: The positive expression rate of GAS7 was 74.7% (40/54) in the group of osteosarcoma and 0% (0/15) in the group of osteochondroma. There was a significant difference in the comparison of GAS expression in these two groups (P 〈 0.05). GAS7 was higher expressed in the samples which complicated with relapse or pulmonary metastasis than the control group (P 〈 0.05). There was no significant association between GAS7 expression and the size of tumor, the gender or the age of the patients (P 〉 0.05). Conclusion: The hyper-expression ot GAST may play an important role in the initiation and development of human osteosarcoma. 相似文献

目的探讨上海市区中老年妇女的脂肪摄入量与恶性肿瘤之间的关系.方法根据上海女性健康研究(Shanghai Women's Health Study,SWHS)队列中74 942名研究对象的基线调查资料,分析了研究对象的脂肪摄入情况,同时采用非条件logistic回归模型分析脂肪摄入量与恶性肿瘤患病之间的关系.结果研究对象脂肪日均摄入量的中位数为27.40(20.43,35.97)g,均数为(29.46±13.41)g.脂肪摄入量与所有肿瘤以及乳腺癌、胃癌、结肠癌和子宫内膜癌的患病率呈明显正相关.若与脂肪摄入量最低组相比,脂肪摄入量最高组相应的上述各部位癌症的OR分别为2.23[95%的可信区间(confidenceinterval.C1)1.83~2.70]、2.31(95% CI1.69~3.17)、3.03(95% CI,1.43~6.43)、2.14(95% CI,0.98~4.67)和3.14(95% CI1.22~8.08),具有统计学意义.脂肪摄入量与肺癌、直肠癌和甲状腺癌各组的OR无统计学意义,但趋势检验显示为具有或接近干统计学意义.结论上海市区中老年妇女的脂肪摄入量与所有肿瘤以及乳腺癌等的患病率呈正相关. 相似文献

有一个调查题目,说是有一个人背着9个包袱准备过河,由于船不能负重,他必须丢掉一个包袱.这9个包袱里,分别是财富、权力、幸福、爱情、健康、机遇、美丽、名誉、诚信等,题目问你:准备丢掉哪一个?这时被调查的人众说纷纭,有的说扔掉权力,有的说扔掉财富,有的说机遇此次扔掉将来还会碰上,甚至有人说名誉丢了还可以重建,等等.题目又问:到最后你也不肯扔掉的是什么?这时几乎众口一词地回答说到最后也不能扔健康,因为如果健康没了,那一切财富、权力、幸福、爱情等等又有什么意义呢?由此可以说明人们对健康的重视.尤其得过一场大病曾与健康失之交臂的人,更深切地体会到健康的宝贵,也更强烈地追求着健康. 相似文献

“医学倘若缺乏必要的人文关怀,就会失去应有的人性温度。”
把病人当作一个真实的人,体恤其受疾病袭击时的痛苦,面临生命危险时的悲伤以及对于爱抚和同情的渴望——是医学人文的应有之意。
数月前,笔者有过一次旁听朱军主任出诊的经历,至今,那个充满人情味的场面还刻在脑海里。他解读病情时的睿智幽默,让患者轻松起来;介绍方案时的通俗明晰,让医学不再陌生;关注病患内心冷暖,让淋巴瘤不再可怕……谈话间不时发出的笑声,弥漫在空气里,让诊室气氛温暖而愉悦。 相似文献

Objective:To study the relationship between expressions of α-,β-catenins and cyclin D1 and the occurrence,infiltration and metastasis of breast cancer.Methods:High sensitive S-P immunohistochemical method was used to detect the protein expressions of α-,β-catenins and cyclin D1 in the 60 cases of breast cancer tissues.Results:Abnormal immunoreactivities of α- and β-catenins were observed in 37(61.7%)and 42(70%)cases of breast Cancer tissues,respectively.There were 28 cases(46.7%)who showed cyclin D1 overexpression.The abnormal expression rates of α -and β-catenins in infiltrating lobular carcinoma(ILC)were significantly higher than those in infiltrating ductal Carcinoma(IDC)(P<0.05),but they had no relations to the extenl of differentiation and lymphatic metastasis of breasl Cancer(P>0.05).The overexpression rate of cyclin D1 was correlated with tumor stage and lymphatic metastasis of breast cancer(P<0.05),but not with histological type and lhe extent of differentiation(P>0.05).Cyclin D1 overexpression was observed in 57.1%(24/42)of these cases that showed abnormal staining of β-catenin,but only observed in 22.2%(4/18)of these cases with normal membranous staining of β-catenin.There was a significantly positive correlation between the abnormal expression of β-catenin and overexpression of cyclin D1(rs=0.321.P<0.05).Conclusion:The abnormal expression of β-Catenin may play an important role in the genesis of breast cancer by triggering cyclin D1 overexpression in breast cancer.The abnormal expressions of α- and β-catenins are not a key factor in malignant cell metastasis in breast cancer,but may also involve in the progress. 相似文献
