下肢慢性静脉功能不全的病因学研究进展

下肢慢性静脉功能不全（chronic venous insufficiency,CVI）是临床上常见的周围血管外科疾病,其发病机制复杂.本文主要从三个方面综述其病因学的研究进展,其中着重介绍了白细胞激活及其诱导的炎症反应在CVI病因学中的重要作用.     

敏感性皮肤研究进展

敏感性皮肤是一种皮肤高度敏感的状态，在这种状态下皮肤极易受到外界因素影响产生皮肤不适。它作为现代社会发生率极高的皮肤问题，影响着人们的生活质量，因此受到皮肤科医生和社会大众的广泛关注。敏感性皮肤的发生原因、诊断、皮肤生理特点等成为了研究热点。     

老年贫血218例病因分析

目的 探讨老年贫血的诊断特点.方法 分析218例老年贫血病例的血常规、骨髓红系增生情况、骨髓形态学及病理学诊断、病因诊断等项目为观察指标.结果 218例老年贫血病例中,男性数量稍多于女性,中位年龄67.9岁.中重度贫血占绝大多数,形态学上以小细胞性贫血比例最高,占42.66%;其次为正细胞性贫血,占35.85%.骨髓红系增生活跃以上者占82.35%;缺铁性贫血为老年贫血最常见的病种(39.44%),其次为巨幼细胞性贫血、骨髓增生异常综合征.缺铁性贫血的病因中摄入不足最常见,占25.66%,肿瘤、溃疡及胃大部切除术后也较多见.骨髓增生异常综合征、巨幼细胞性贫血和慢性再生障碍性贫血为老年全血细胞减少病例的常见病种.结论 老年人属弱势群体,老年贫血病例中缺铁性贫血和营养不良性贫血比例高. Abstract： Objective To explore the diagnostic characteristics of anemia in the elderly. Methods To measure and analyze the eric status of bone marrow, diagnosis according to morphology and biopsy of bone marrow, and etiology of anemia(IDA) in 218 cases of anemia in the aged. Results In these 218 cases male patients were slightly more than female patients. Median age was 68.9. Ratio of cases with macrocytic anemia was the highest(42.66%), ratio of cases with active erythropoietic status was 82. 35%. Iron deficiency anemia was the most common anemia in the elderly(39. 44%), and megaloblastic anemia and myelodysplastic syndrome (MDS) were also frequent. Insufficient ingestion was the most common cause of IDA(25.66 %),and tumors,digestive ulcers and postgastrectomy were also the common causes. MDS,megaloblastic anemia and chronic aplastic anemia(CAA) were the common anemia in geriatric population with pancytopenia. Conclusions Geriatric population is the fragile group. Ratio of cases with anemia due to IDA and malnutrition is high in cases of anemia in the elderly.     

肝移植术后胆道并发症的病因及诊治进展

肝移植术后胆道并发症(BC)做为肝移植术后影响肝移植远期疗效的重要并发症业已引起临床和研究人员的重视。胆道并发症是指具有临床表现,有影像学依据,需要进行手术或介入性治疗的胆道狭窄、梗阻及胆瘘等,其发生与外科操作、缺血再灌注损伤、供肝保存性损伤等因素有关。该文对BC的病因及诊治进展予以综述,以期进一步开展BC的临床和实验研究。
