原发性肝癌寄生性供血与介入治疗

目的探讨原发性肝癌寄生性供血情况,提高TACE治疗肝癌的疗效。方法本组30例原发性肝癌患者行常规腹腔动脉造影及寄生血管探查,并对其行超选择插管及化疗栓塞治疗（TACE）。结果30例患者共见32条肝外寄生血管,其中膈下动脉（10/32）,肠系膜上动脉（8/32）,胃十二指肠动脉及胃网膜动脉（6/32）,胃左动脉（4/32）占多数。5条寄生性血管因细小迂曲未能成功行超选择插管只给予化疗灌注治疗,其余27条寄生血管均行超选择插管和化疗栓塞治疗,一月后复查,CT示肿瘤缩小,碘油沉积致密完全。结论原发性肝癌寄生性供血较为常见和多变,认识原发性肝癌寄生性供血的特点及规律并进行双重血管栓塞,能进一步提高原发性肝癌TACE治疗效果。     

Rickettsia felis: from a rare disease in the USA to a common cause of fever in sub-Saharan Africa

Rickettsia felis is a spotted fever group rickettsia that has been definitely described in 2002. Within the last 20 years, there have been a growing number of reports implicating R. felis as a human pathogen, parallel to the fast-growing reports of the worldwide detection of R. felis in arthropod hosts, mainly the cat flea Ctenocephalides felis felis. R. felis is now known as the agent of the so-called flea-borne spotted fever, with more than 70 cases documented in the literature. Recently, two studies respectively conducted in Senegal and Kenya, have challenged the importance of R. felis infection in patients with unexplained fever in sub-Saharan Africa. We focus here on the epidemiological and clinical aspects of R. felis infection. More studies are needed, including the study of other arthropod vectors, but it can be speculated that R. felis infection might be an important neglected agent of fever in sub-Saharan Africa.     

温度对豫南罗索线虫寄生前期幼虫存活力和感染力的影响

应用定量的方法，对豫南罗索线虫寄生前期幼虫在不同温度下的存活力和感染力进行系统观测。结果：在一２℃～２℃下，９０％以上的幼虫可存活８天，并保持相当强的感染力。在２６℃～２８℃和１６℃～１８℃下，９０％的存活时间分别为２４小时和４８小时。结果表明，一２℃～２℃低温贮存的方法可延长该幼虫的寿命，并保持其感染力。
