动物与临床胆道梗阻和胆道炎症时胆管组织PGI_2和TXB_2的变化

采用放射免疫法测定实验性胆道炎症兔胆系组织以及几种胆道疾患病人胆系组织中６－ｋｅｔｏ－ＰＧＦ１α与ＴＸＢ２的含量。结果显示：动物模型组与病人组的上述两指标均显著增高；ＡＯＳＣ病人的ＴＸＢ２增高更明显，而胆道梗阻病人胆管组织无此变化。提示前列腺素类及血栓素对胆道炎症的发生可能有关，ＴＸＢ２的负性作用尤为重要。     

彩色多普勒超声监测肝移植术后门静脉并发症

目的 探讨彩色多普勒超声(CDI)监测肝移植术后门静脉并发症的应用价值。方法 对107例次原位肝移植患者于术前、术后应用CDI进行连续监测，监测指标包括门静脉主干内径、血流速度、血流量、血流频谱、侧支循环及腹水量等。结果 4例受者术后出现门静脉并发症：门静脉狭窄2例，门静脉狭窄并血栓形成1例，门静脉右支闭塞1例。2例门静脉主干血流量明显减少者接受经皮腔内血管成形术治疗后，门静脉高压缓解；而CDI提示门静脉血流量末见下降的2例患者，仅接受保守治疗，存活时间均超过1年。结论 彩色多普勒超声动态检查对肝移植术后门静脉并发症较为敏感，作为无创性检查手段可用于肝移植术后门静脉并发症的监测。     

直肠后矢状纵切及心形吻合治疗先天性巨结肠

目的 提高先天性巨结肠的手术疗效。方法 回顾1992年8月至2002年8月应用直肠后矢状纵切、心形吻合技术治疗诊断明确的先天性巨结肠患儿106例，分析疗效及并发症防治。结果 106例患儿术后全部随访2个月～10年，并发小肠结肠炎5例，偶有污粪2例，便秘复发3例，无盆腔、腹腔感染及吻合口狭窄发生。结论 应用直肠后矢状纵切、心形吻合技术治疗先天性巨结肠，可提高手术疗效，减少并发症。     

Impaired colour discrimination in Huntington's disease

Colour discrimination and visual contrast perception were investigated in 18 patients with Huntington's disease (HD) and in 18 age- and sex-matched healthy volunteers using the Farnsworth-Munsell 100 Hue test (FM) and stationary contrast targets. The mean total error score (MTES) and the partial scores for the “red-green” and the “blue-yellow” axes in the FM of the patients with HD were significantly elevated as compared to controls (MTES in HD: 113.0 ± 90.8; MTES in controls: 19.2 ± 8.8). The spatial contrast sensitivity in HD patients was normal. The colour perception dysfunction indicates that the visual system is affected in HD. The visual disorder may be related to an imbalance of certain neurotransmitters in the visual system of HD patients. Possible anatomical sites of the dysfunction responsible for colour discrimination abnormalities could be the retinal cone system and/or impaired parvocellular central visual pathways in HD.     

肺部三种疾病模糊数学鉴别诊断的探讨

本文对肺部三种疾病１５３６例患者的病历资料，按病种作了统计归类。运用模糊数学原理建立了征候一疾病间的模糊关系矩阵，用参量加权模糊综合评判模型，对肺部三种疾病鉴别诊断的符合率达８２．９１％以上，因此认为文中建立的模型，对肺部三种疾病鉴别诊断具有参考价值。     

Evoked potentials in patients with non-neurological Wilson's disease

Summary In Wilson's disease neurological manifestations result from the damage in the basal ganglia, even if a widespread degeneration of the brain occurs. The few studies performed using evoked potentials with the aim of identifying subclinical dysfunction in the three major sensory pathways have never shown abnormalities in patients without neurological manifestations. To verify this observation we studied 12 patients suffering from Wilson's disease in a pre-neurological stage by using pattern visual evoked potentials (VEPs), somatosensory evoked potentials (SEPs) to median nerve stimulation and brainstem auditory evoked potentials (BAEPs). Four of these patients had not yet been treated with penicillamine or trientine (triethylenetetramine dihydrochloride), while the remaining 8 patients were on treatment for at least 1 year. In 3 patients of this second group and in 1 patient of the first group we observed a significant (3 SD over the mean) increase in P100 wave latency, while SEPs and BAEPs were found to be abnormal in only 1 patient, respectively.     

性传播疾病危险人群乙型肝炎和丙型肝炎病毒感染的血清流行病学调查

通过对４３１名卖淫妇女和１０９名正常妇女ＨＢＶ和ＨＣＶ感染的血清学指标的检测、性传播有关因素的调查，发现卖淫妇女ＨＢＶ和ＨＣＶ感染中的抗－Ｈｋｃ为４３．１５％，抗－ＨＢｓ为３６．８９％，ＨＢｓＡｇ为１０．４４％，抗－ＨＣＶ为９．５１％，明显高于正常妇女；有性传播疾病者ＨＢＶ和ＨＣＶ的各项感染指标也明显高于正常妇女。卖淫妇女的抗－ＨＣＶ感染率有随年龄增长而增高的趋势，与卖淫时限长、卖淫次数多有明显差别，这表明卖淫妇女中有较严重的ＨＢＶ和ＨＣＶ感染。     

Carcinoid tumors and inflammatory bowel disease.

Three cases are described in which carcinoid tumors arose in previously established inflammatory bowel disease: two were in the ileum in cases of Crohn's disease, and one was in the rectum in a case of ulcerative colitis. Review of this association in the literature suggests that it may be more than fortuitous.
