AIM:To report our experience of gastrointestinal stromal tumors (GISTs) during the last 29 years. METHODS:Thirty two cases of GIST referred to our Institution from the 1st January 1981 to the 10th June 2010 were reviewed. Metastases,recurrence and survival data were collected in relation to age,history,clinical presentation,location,size,resection margins and cellular features. RESULTS:Mean age was 63.7 years (range,40-90) and incidence was slightly higher in males (56%). R0 resection was performed in 90.7% of cases,R1 in 6.2% (2 cases) and R2 in 3.1% (one case). Using Fletcher’s classification 8/32 (25%) had high risk,9/32 (28%) intermediate and 15/32 (47%) low risk tumors. Follow-up varied from 1 mo to 29 years,with a median of 8 years; overall survival was 75% (24/32),disease-free survival was 72% and tumor-related mortality was 9.3%. Three patients with high risk GIST were treated with imatinib mesylate:one developed a recurrence after 36 mo,and 2 are free from disease at 41 mo. CONCLUSION:Surgical treatment remains the gold standard therapy for resectable GISTs. Pathological and biological features of the neoplasm represent the most important factors predicting the prognosis.

2020年,新冠病毒全球大流行对人类健康带来了严峻的威胁,也促使人们格外重视疫苗接种。疫情叠加、人口老龄化,更使得老年人群的疫苗接种成为公众关注的焦点话题之一。截至2019年底,我国60岁及以上的人口超过2.5亿,占总人口的18.1%,是全球老年人口最多的国家。  随着年龄的增长,老年人组织细胞和循环系统中促炎细胞因子的基线水平升高,这种现象被称为“炎症衰老”。与炎症衰老相应的是机体对致病性威胁或

疫情发生后, 人们对养生和健康有了更多的关注,网上流传的代餐食品更是大受吹捧。在某电商平台搜索“代餐”二字,瞬间就会出现100多页的推荐内容,大都标注有“无糖”“低卡”“饱腹”“减脂”等字样。  在我国,超重和肥胖的成年人比例在40%以上。这意味着,每5个成年人中就有2个需要进行体重管理。《中国超重/肥胖医学营养治疗专家共识(2016)》中提到,配合营养代餐的强化生活方式干预,比单纯的膳食支持和教

啥叫贫血  血常规检查中,红细胞(RBC)减少、血红蛋白(Hb,大家喜欢称为“血色素”)减少或血细胞比容(HCT,就是以前说的“血球压积”)减少,都称为贫血。  正常Hb值在不同性别、不同年龄、不同海拔高度居住地、不同生理状态的人,会有一些差异。比如婴儿、儿童、妊娠妇女以及血液稀释时,Hb浓度较低,久居高原地区的居民、因脱水而血液浓缩时,Hb浓度较高。  一般认为,在海平面地区,我国成年男性Hb低

消毒剂顾名思义就是指能够杀菌消毒的物质。我们生活中有各种各样的杀菌消毒剂,常用的有酒精、碘伏、84消毒液、季铵盐类等。  常用消毒剂按消毒效果分类有3种:高效消毒剂(灭菌剂)、中效消毒剂、低效消毒剂。依据使用剂型的分类有5种:气体消毒剂、泡沫消毒剂、液体消毒剂、凝胶消毒剂、固体消毒剂。按化学成分,可分为8类:醇类消毒剂、含氯消毒剂、二氧化氯消毒剂、过氧化物类消毒剂、含碘消毒剂、含溴消毒剂、酚类消毒
