下肢动脉硬化闭塞症的外科治疗

目的:探讨外科治疗下肢动脉硬化闭塞症的临床经验。方法:从1995年7月～2002年7月共对292例(313条肢体)动脉硬化闭塞症病人进行外科治疗,其中20条患肢施行解剖外血管重建术,38条患肢施行了腔内外科治疗或合并开放性血管重建手术,255条患肢施行了开放性手术重建下肢血供。结果:手术成功者患肢的踝肱指数与术前比较显著增加(P<0.01),症状得到明显改善。平均随访时间3.1年(0.5～7年),解剖外重建组移植血管一期通畅率为56%,腔内外科组通畅率为78%,开放性手术组通畅率为72%。结论:病人的全身情况、动脉病变的范围和程度是选择下肢动脉硬化闭塞症外科治疗方法的主要依据,为取得较好的长期通畅率和临床效果需要重视围手术期处理和术后随访。     

胡塞尔现象学本质直观理论初析

胡塞尔继承了西方哲学史上的本质主义路线，严格区分事实和本质、形式本质和实质本质，提出了他的现象学本质观。本质观使我们对“本质”的了解获得了从柏拉图主义和洛克主义、实在论和唯名论非此即彼之争中挣脱出来的可能。     

低能级体外冲击波碎石治疗肾鹿角形结石

目的探讨低能级体外冲击波碎石(extracorporeal shock wave lithortripsy,ESWL)治疗肾鹿角形结石的效果. 方法对18例鹿角形结石进行体外冲击波治疗.碎石能级1～3级,冲击次数1 800～3 000次,脉冲间隔60 ～80次/min,工作电压10～12.75 kV. 若结石直径>3 cm,在碎石前预先插入双J管,防止石街形成.对直径>4 mm的残余结石,再次行ESWL,直至结石完全消失. 结果所有病人耐受良好,治疗结束能自行回家.除1例碎石失败外,余17例经ESWL治疗成功.治疗3～9次,至完全排除结石.66例次(66/77,85.7%)术后有1～2次肉眼血尿.5例出现石街,长1.9～5.2 cm,4例石街经再次碎石成功,1例输尿管镜取石. 结论低能级ESWL治疗肾鹿角形结石是一种安全、有效的方法.     

射频消融治疗肝肿瘤315例报告

目的总结1999年6月至2003年8月用射频消融（radiofrequency ablation，RFA）治疗315例肝肿瘤病人的病例资料，探索RFA治疗肝肿瘤近远期疗效。方法采用了一次定位、多点穿刺，RFA联合肝动脉栓塞（TAE）、选择性门静脉栓塞（SPVE）治疗直径5～13cm的大肝癌，及经皮经肺经膈肌RFA治疗膈顶部肝癌。结果总并发症发生率为5．1％，无一例住院期间死亡。AFP阳性的169例肝癌病人中，RFA后有124例（73．6％）明显降低，其中有95例（56．2％）转阴。半年生存率为89．5％，1年生存率为80．1％，18个月生存率为61．4％，24个月生存率为48．3％，〉36个月生存率为35．6％。结论采用TAE、SPVE及RFA一次定位多点穿刺法治疗无手术切除指征的中晚期（含大肝癌）的病人，疗效明显，总并发症发生率低。     

Voiding patterns in men and women with lower urinary tract symptoms combined with nocturia

AIM: We evaluated differences between men and women with lower urinary tract symptoms (LUTS) combined with nocturia. METHODS: A total of 71 age-matched female-male pairs (median 58, range 20-81 years) who had moderate to severe LUTS and nocturia of more than once per night were enrolled in this study. RESULTS: In the younger group (<50 years), the International Prostate Symptom Score (I-PSS) results of the sexes were not significantly different. However, although total I-PSS results in the elderly group (> or =50 years) were not significantly different, quality of life index scores for women were higher (P = 0.002). On frequency-volume (FV) charts, mean total daytime voided volume (DVV) was significantly higher in younger men than in younger women (P = 0.017), but the mean nocturnal polyuria index (NPi) for women was higher than that for men (P = 0.047). However, maximum DVV (P = 0.009), mean DVV (P < 0.0001), total DVV (P < 0.0001), and mean nocturnal urine volume (P = 0.009) were significantly higher in elderly men than in elderly women. However, numbers of daytime voids were not different. CONCLUSION: Elderly women with LUTS have lower functional bladder capacities than elderly men, as suggested by their smaller mean voided volumes. However, no significant differences were observed between numbers of daytime voids, which was probably due to the smaller total daytime voided volumes of elderly women. In addition, although NPi for younger women and nocturnal urine volume for elderly men was higher, no other differences were observed in terms of other night-time parameters.     

鼻内镜联合显微镜经鼻腔蝶窦及中颅窝手术

Pituitary abscess in a pregnant woman.

Pituitary abscess is a rare and potentially lethal condition. Pituitary abscess in a pregnant woman has not been previously described. A 38-year-old pregnant woman (34 weeks gestation) with a pituitary mass complained of a progressive headache and sudden visual impairment. She was afebrile and had no inflammatory symptoms on admission. On MRI, the preoperative diagnosis was pituitary adenoma with sphenoid sinusitis. She underwent an uncomplicated transsphenoidal procedure for removal of the pituitary mass. The next day, labor commenced and a healthy preterm baby was delivered. Pathologic examination of the intrasellar mass showed polymorphonuclear cells, debris and no tumor cells. The sellar contents were cultured and Streptococcus viridans was grown. To our knowledge this is the first case of pituitary abscess reported during pregnancy. Although the patient was pregnant, the transsphenoidal approach was safe for the mother and the fetus. Surgical drainage and antibiotic therapy are required for the definitive treatment of this condition.
