超声对宫角妊娠的诊断及治疗意义

目的 探讨对误诊率高，危害大的罕见特殊部位宫角妊娠的诊断和治疗。方法 对我院1991-2001年收治的宫角妊娠临床资料进行回顾性分析。结果 宫角妊娠17例中误诊宫内妊娠行人流失败4例。13例行腹部手术，3例行B超监视下人流术，1例行子宫动脉栓塞术。结论 宫角妊娠临床诊断困难，误诊率高，破裂后造成迅猛的腹腔内出血，应提高对少见部位宫角妊娠的认识，减少孕妇死亡。     

Hb F-Xin-Su or A gamma I73(E17)Asp----His: a new slow-moving fetal hemoglobin variant

A slow-moving gamma chain variant was discovered in the cord blood of an infant born to parents of the Han nationality from Jiangsu. The variant, which migrated electrophoretically at alkaline pH between Hb A and Hb D, was characterized by an Asp----His substitution at gamma 73, while residues gamma 75 and gamma 136 were occupied by Ile and Ala, respectively. As the A gamma T-chain was also present, this baby has two types of abnormal gamma-chain. The variant was named Hb F-Xin-Su.     

均一吸收体中SPECT重建多解性的探讨

通过对重建图像噪声特性的分析，间接证明ＳＰＥＣＴ的解具有多样性。分别用ＴｒｅｔｉａｋＭｅｔｚ、Ｇｕｌｂｅｒｇ、富谷武浩等推导的３种等价重建方法和Ｂｅｌｉｎｉ等推导的重建方法，经计算机模拟重建衰减均匀分布的图像，先预置相同的重建图像的空间分辨率，再比较它们的噪声特性。两种方法重建图像的噪声分布：前者近图像边缘时增大，而后者减小，从而间接证明在假定均匀衰减条件下，ＳＰＥＣＴ的重建有多解性。     

Effect of cordarone on the eye (results of long-term follow-up of the treatment and prevention of arrhythmia)

Thirty-one patients who received a prolonged maintenance therapy with cordarone to treat and prevent cardiac arrhythmias underwent an ophthalmologic examination. The treatment lasted 1.5 to 51 months. The signs of keratopathy were detected in 24 (77.4%) patients using a slit lamp biomicroscopy. There is a relationship between the severity of keratopathy and a daily dose of cordarone: in most cases signs of stage I keratopathy were detectable when the daily dose was up to 200 mg. Keratopathy appears to be reversible after the drug has been discontinued.     

Indices of the body's neurohumoral activity and hemodynamic types in hypertension

A study of neurohumoral parameters in patients with essential hypertension and different hemodynamic types demonstrated different patterns of hormonal change in patients with hyperkinetic, eukinetic and hypokinetic hypertension. Elevated blood tri-iodothyronine and thyroxine, seen in patients with hyperkinetic hemodynamic type, and increased catecholamine excretion in patients with hypokinetic hemodynamics may be indicative of the pathogenetic significance of the hormones in question for the formation of respective variants of essential hypertension.     

APPLICATION OF ACUPOINT-INJECTION THERAPY TO PAIN SYNDROME: CLINICAL ANALYSIS OF 250 CASES

In this paper,250 cases of headache,shoulder pain,lumbago and leg pain weretreated with 20％Angelicae Sinensis mixed with Vitamine B_(12) point-injection therapy.The total effective rate was 95.2％and in which the cure rate was 53.6％.Authors have found a close correlation between the effectiveness and the duration of disease.     

Binswanger's disease in the absence of chronic arterial hypertension

Summary The cerebral changes are described in a woman of 54 who suffered from Binswanger's encephalopathy: there were no signs or symptoms of chronic arterial hypertension. The disease presented as dementia of about 3 years duration. Computed tomography of the brain 2. 5 years before her death showed bilateral widespread hypodense lesions in the cerebral white matter. She died of an asthmatic attack. Autopsy disclosed extensive bilateral degeneration of the central white matter, lacunes and gliosis. Severe obliterative arteriolosclerosis occurred in the meningeal vessels and those supplying the affected parts of the brain. Light microscopy showed that the most severe lesions occurred in the arterioles. Immunohistochemistry demonstrated profound extravasation of plasma proteins chiefly albumin, indicating dysfunction of the blood-brain barrier. Thus, the lesions characteristic of Binswanger's encephalopathy may develop in the absence of chronic arterial hypertension. Additional pathogenic factors, possibly genetic predisposition to vascular injury may play a role in the development of this condition.Supported by grants from the Swedish Medical Research Council, Project No 12X-03020 and 1987 Års Stiftelse för Strokeforskning     

川芎嗪和维拉帕米对缺血性急性肾衰初期保护效应的实验研究

１８只犬切除右肾，钳夹左肾动脉６０分的肾缺血模型，再灌注５小时。将动物随机分成对照组、川芎嗪组及维拉帕米组。观察尿量、菊糖清除率、利钠指数、平均动脉压及心率；再灌注５小时取肾组织作形态学检查。结果显示川芎嗪对肾功能及形态有保护作用，维拉帕米则无此作用，提示在手术中有肾缺血时以川芎嗪作为肾保护药物优于维拉帕米。
