主动脉瘤腔内隔绝术

主动脉的扩张性疾病可分为真性动脉瘤、动脉夹层（aortic dissection，AD）和假性动脉瘤。随着这类疾病发病率和检出率逐年提高，人们对它们的关注程度也不断提高。如何治疗他们，成为摆在临床医生面前的难题。1991年，Parodi率先报告了支架-人造血管复合体（直型）在腹主动脉瘤治疗中的应用，成为腔内血管治疗历史上的一个里程碑。随着医疗器械的不断发展、技术的不断完善、经验的不断积累总结，微创、安全的腔内隔绝术在主动脉扩张性疾病中的治疗中得到广泛的认可，并在全球范围内迅速推广。     

Analysis of brain-stem auditory evoked potential and visual evoked potential in patients with Parkinson disease

INTRODUCTION The exact cause of Parkinson disease (PD) has not been known yet[1]. The overwhelming progress had been made in the treatment and pathogenesis of PD in recent 30 years, especially 10 years[2]. But it is still no way now to prevent or postpone…     

重度苯妥英钠中毒的药学监护

目的首先确定中毒药物,然后通过测定血药浓度以了解中毒程度,为重度苯妥英钠中毒患者临床抢救治疗提供依据。方法间隔一定时间采集患者静脉血,萃取血中药物,在211 nm处以反相高效液相色谱法定性,明确中毒药物并测定血药浓度。结果在苯妥英中毒患者中最高血药浓度为68.94 mg.L-1,接近治疗浓度上限的3.5倍。结论患者为重度中毒,危及生命,需临床药师与临床医师积极配合,施行全程药学监护。     

Effects of bimatoprost 0.03% on ocular hemodynamics in normal tension glaucoma.

PURPOSE: The aim of this study was to investigate the effects of bimatoprost 0.03% on ocular hemodynamics in patients with normal tension glaucoma (NTG). METHODS: Twenty-two (22) patients with NTG were consecutively recruited. After basic eye examination and diurnal intraocular pressure (IOP) measurement, color Doppler imaging was used to measure the peak systolic and end diastolic velocities and resistive index of the central retinal, lateral posterior ciliary, and medial posterior ciliary arteries. Patients received bimatoprost 0.03% for 4 weeks, and these measurements were then repeated. The worse eye of each NTG patient was used in the statistical analysis. RESULTS: Bimatoprost 0.03% significantly reduced mean IOP from 15.1 +/- 3.8 mmHg at baseline to 12.0 +/- 2.9 mmHg after treatment in our sample of NTG patients (P < 0.001). No significant changes in blood velocities or resistance indices were observed in the retrobulbar vessels after the 4-week treatment. CONCLUSIONS: Topical bimatoprost 0.03% significantly reduced IOP in our NTG patients without causing significant hemodynamic changes in the retrobulbar vessels.     

清热解毒液雾化吸入防治留置胃管致咽喉部不适的疗效观察

目的观察清热解毒液(中药制剂)雾化吸入对防治留置胃管致咽喉部疼痛、痰多等不适的效果。方法将80例需要留置胃管的胃肠减压的病人随机分为对照组和观察组各40例。对照组按常规的方法进行护理,观察组在常规护理的基础上加用20毫升清热解毒液雾化吸入,每日2次,持续到拔除胃管。结果观察组病人的咽喉部痰量明显比对照组少(χ2=9.0383,P<0.005);观察组病人咽喉部疼痛明显比对照组少而且轻(χ2=19.5267,P<0.005),时间还推后。结论清热解毒液雾化吸入能有效预防及减轻留置胃管致咽喉部的疼痛、咽燥、痰多等不适。     

应用组织芯片技术研究光暴露皮肤与非光暴露皮肤中PCNA的表达

目的:比较光暴露与非光暴露皮肤中增殖细胞抗原的表达。方法:组织芯片按文献报道方法制备,用免疫组化链霉素亲和素-生物素法(Streptavidin-Peroxidase SP法)检测,一抗为1:100鼠抗人单克隆抗体。结果:36例光暴露皮肤组织中14例(38.9%)阳性;19例非光老化皮肤中18例(94.7%)阳性(χ2=4.2,P<0.01)。结论:光暴露部位皮肤组织PCNA蛋白表达较非光暴露部位皮肤组织表达明显减少。日光对细胞增殖因子的表达起抑制作用。推测日光对皮肤组织的增生能力有阻滞作用,加速皮肤老化。
