特发性室性心动过速QRS波群电轴与成功消融关系的探讨

为探讨特发性室性心动过速（ＩＶＴ）体表心电图ＱＲＳ波群电轴与射频消融成败的关系，对２３例ＩＶＴ进行射频消融治疗，其中左室ＩＶＴ１５例、右室ＩＶＴ８例。在左室ＩＶＴ中，１０例ＱＲＳ波群电轴左偏（－８１°±９°）者均消融成功；５例电轴右偏者（＋１１０°～＋２３０°）中只有１例（＋１１０°）消融成功。电轴左偏与电轴右偏患者的消融成功率比较（１０／１５ｖｓ１／５），差异有显著性，Ｐ＜０．０５。在右室ＩＶＴ中，５例电轴正常或轻度右偏患者均消融成功；另３例电轴左偏患者均消融失败。结果提示室性心动过速（ＶＴ）时ＱＲＳ波群电轴对术前判断ＶＴ的起源部位及消融难易程度会有所帮助。

State of knowledge of helminth fauna of freshwater fishes of Poland

A total 89 fish and lamprey species has been recorded from Polish freshwater habitats. Twenty-seven of them (30.3%) have not been surveyed for parasitic helminthes. Some of the latter fishes are either rare or not easily accessible. Other live only in specific habitats in scattered localities. An important obstacle for studying parasite faunas of some fishes may be their status on an endangered species. Among the non-surveyed fishes, are those which have been relatively recently introduced to Poland or migrated there on their own. The present paper attempts to review all hitherto not studied helminthologically fish species, their habitats, localities and current protection status.     

高血压降压治疗目标的再认识

根据传统的高血压水平的定义,1993年WHO高血压治疗指南提出血压控制目标为<140/90mm Hg(1mm Hg=0.133kPa),但是并非所有患者都必须将血压降至同一水平,而应根据患者情况进行个体化治疗。Framingham进行的一项长达10～12年的心血管事件研究发现,第5年后,正常上限血压[收缩压(SBP     

Lack of correlation of degree of villous atrophy with severity of clinical presentation of coeliac disease

BACKGROUND AND AIM: Both the clinical presentation and the degree of mucosal damage in coeliac disease vary greatly. In view of conflicting information as to whether the mode of presentation correlates with the degree of villous atrophy, we reviewed a large cohort of patients with coeliac disease. PATIENTS AND METHODS: We correlated mode of presentation (classical, diarrhoea predominant or atypical/silent) with histology of duodenal biopsies and examined their trends over time. RESULTS: The cohort consisted of 499 adults, mean age 44.1 years, 68% females. The majority had silent coeliac disease (56%) and total villous atrophy (65%). There was no correlation of mode of presentation with the degree of villous atrophy (p=0.25). Sixty-eight percent of females and 58% of males had a severe villous atrophy (p=0.052). There was a significant trend over time for a greater proportion of patients presenting as atypical/silent coeliac disease and having partial villous atrophy, though the majority still had total villous atrophy. CONCLUSIONS: Among our patients the degree of villous atrophy in duodenal biopsies did not correlate with the mode of presentation, indicating that factors other than the degree of villous atrophy must account for diarrhoea in coeliac disease.
