ERCP术后胰腺炎的研究进展

随着内镜诊疗技术的发展，内镜逆行胰胆管造影（ERCP）在胆管及胰腺疾病诊断和治疗中的优点已被广泛接受，作为一种侵袭性检查手段，也存在相关的并发症，ERCP术后胰腺炎（post-ERCP pancreatitis，PEP）是最常见的并发症之一，国外报道其发生率为2．0％～20．0％，国内报道其发生率为11．5％，而ERCP术后高淀粉酶血症的发生率可高达75％。目前对此研究较多。现就PEP的研究进展做一综述。     

低场磁共振三维增强血管造影应用初探

三维增强磁共振血管造影(3D CEMRA)是继时飞法和相位法2D磁共振血管成像后新近开发的MRA技术,中高场磁共振CEMRA技术应用较成熟,而在低场磁共振的应用报道较少。我院自2005年1月至2006年5月对28例颈、体部血管行CEMRA检查,对主动脉、下腔静脉、门静脉及其分支成像进行了探讨。现报告如下。1材料与方法1·1本组28例,男19例,女9例,年龄27~68岁,平均47岁。检查血管包括胸主动脉、腹主动脉、头臂动脉、下腔静脉、门静脉。1·2仪器及扫描参数采用0·35T永磁MRI扫描机(GE公司生产的Signa Ovation)。扫描序列为三维快速扰相梯度回波(SP…

裂头蚴病的流行病学调查和公共卫生学意义

裂头蚴（Sparganum）的成虫为裂头绦虫，它的生活史中需要3～4个宿主。第一中间宿主是剑水蚤，第二中间宿主主要是蛙、蛇、鸟类、人和猪等多种脊椎动物。裂头蚴具有很强的收缩和移动能力，特别是在蛙大腿或小腿的肌肉中居多，多卷曲穴居在肌肉间隙的一小囊内，或游离于皮下。蛙科动物作为重要的第二中间宿主，蛙的裂头蚴病（Spsrganpsis）在世界的一些地区，     

环戊硫酮治疗干眼的临床疗效评价

Objective To investigate anethol trithione therapic efficiency on dry eye. Methods It was a prospective random double-blind controlled study. Eighty cases diagnosed dry eye in Ocular Surface Out-patient Clinic of Xiamen University Affiliated Xiamen Eye Center from 2006 to 2008 were divided into two groups: anethol trithione group and control group, 40 cases in each group. Every group was then divided into two subgroups: weak dry eye subgroup, middle and severe dry eye subgroup. All groups had been added with 0.05% refresh drops. All patients had been detected and evaluated by subjective symptoms of dry eye, visual acuity,corneal fluorescent staining(F1), break-up time(BUT) and Schirmer Ⅰ test (SⅠT) at pre-therapy and 3,7,28 d of post-therapy. All groups had been compared and analyzed by F test and sample mean difference (SMD) or median difference (MD) comparison between pre-therapy and post-therapy. Results Except of tear and red eye, the other subjective symptoms of dry eye, F1, BUT and SⅠT of weak dry eye subgroup of both groups had been improved at 7 d after therapy. Only those of middle and severe dry eye subgroup of anethol trithione group had been improved at 7 d after therapy compared with those of pre-therapy: SMD=0.96 (visual tiredness), 1.26 (dry and unsmooth sensation), 0.82 (foreign body sensation), 1.28 (burning sensation), 1.05 (photophobia), 1.48 ( pain ) ; MD=0.30 (visual acuity), 4.00 (F1) ,5.00 (BUT), 5.00 (SⅠT) [F=15.30 (visual tiredness), 15.68 (dry and unsmooth sensation ), 13.56 (foreign body sensation), 20. 91 ( burning sensation ), 18.90 (photophobia), 27.22 ( pain ), 10.54 (visual acuity), 188.21 (F1) ,261.76 (BUT) ,269.05 (SⅠT) ;P<0. 05]. Those of middle and severe dry eye subgroup of control group hadn't significantly been improved at 28 d after therapy: SMD=0.10 (visual tiredness) ,0.16 (dry and unsmooth sensation) ,0.09 (foreign body sensation) ,0.38 ( burning sensation ), 0.24(photophobia) ,0.36 (pain) ,0.23 (red eye) ; MD=0.10 (visual acuity) ,0.50(F1) ,0.50(BUT), 0.50(SⅠT) [F=1.76 (visual tiredness), 1.61 (dry and unsmooth sensation), 1.02 (foreign body sensation),2.39 (burning sensation), 2.42 (photophobia), 2.73 ( pain ), 2.55 ( red eye ), 1.46 ( visual acuity) ,2.35 (F1) ,2.90 (BUT) ,2.76 (SⅠT) ; P>0.05]. SⅠT of anethol trithione group had been improved more significantly after therapy (F=13.77, P<0.05). Conclusion Anethol trithione could significantly improve middle and severe dry eye patients' symptoms and signs whose lacrimal gland function survival and it has clinical application value.     

医源性胆管缺血性损伤

肝外胆管的血液供应比较脆弱,有3个主要原因:其一,胆管的血供不像肝脏由动脉和门静脉双重供应,而仅由单一的动脉供给;其二,供给胆管血液的动脉均为与胆管伴行的终末支血管,口径较小;其三,这些终末支小动脉在胆管壁外的交通支较少.上述胆管供血动脉的解剖特点导致了胆管容易受到缺血性损伤.缺血性胆管损伤多为医源性,如肝移植、肝脏介入治疗、胆管和涉及胆管的胰腺手术等.
