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.

冠心病患者颈动脉粥样硬化检测及意义

目的　探讨冠心病患者与颈动脉粥样硬化之间的发生关系。方法　主要应用彩色多普勒超声技术检测 10 2例冠心病患者的颈动脉 ,对其中 34例进行冠状动脉造影检查。结果　为各组冠心病患者颈动脉管壁内 -中膜厚度 ,斑块指数均显著增高 ,其中心肌梗死患者伴有明显的血流参数异常 ,34例患者冠状动脉造影与颈动脉超声检查符合率为 75 % ,而且冠状动脉病变越重 ,颈动脉硬化发生率越高。结论　颈动脉粥样硬化程度可间接反映冠状动脉病变程度。
