胃镜检查诊断十二指肠钩虫病45例报告

钩虫病是小肠寄生虫病,常与上消化道病变并存,常规胃镜检查时发现十二指肠钩虫具有偶然性。本文在行胃镜检查的14 850例中检出十二指肠钩虫45例。提示医师在常规胃镜检查过程中,对十二指肠尤其降部应仔细观察,一旦发现寄生虫应及时取出化验确诊。     

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.     

外科学教学中的审美教育

医学审美教育是医学生全面素质教育不可分割的组成部分,笔者结合长期外科教学实践,阐述了在外科学教学中运用医学美学原理对外科学的美进行开发和挖掘,使医学生在熟练掌握外科学基本理论和基本技能的同时,潜移默化地接受美的教育,美的熏陶,更能激发他们对外科学的热爱和兴趣,达到全面提高医学生整体素质的目的。     

凯时治疗慢性重型肝炎患者疗效观察

目的探讨凯时即前列地尔脂微球载体制剂（Lipo-PGE1）治疗慢性重型肝炎的疗效。方法将84例慢性重型肝炎患者随机分成两组，对照组予综合治疗及对症治疗，治疗组在该基础上加用凯时10μg溶于5％葡萄糖注射液250ml中静脉缓慢滴注，1次/d，疗程为4周。结果治疗组对慢性重型肝炎的疗效优于对照组（P〈0．01），肝功能改善优于对照组（P〈0．01）。结论Lipo-PCEI是一种治疗慢性重型肝炎安全、有效的药物。     

64层CT下肢动脉成像技术研究

目的探讨64层CT下肢动脉成像强化质量的对比剂注射方式。方法前瞻性地选择60例疑诊下肢动脉病变的病人,利用64层螺旋CT行下肢动脉CT血管成像。采用不同的扫描和重建参数,应用370mgI/100ml浓度的对比剂100ml团注或采用先70ml的对比剂后50ml的0.9%生理盐水用双筒高压注射器分别以4.0ml/s的注射速度团注入肘静脉,应用对比剂追踪触发扫描方式待腹主动脉CT阈值达120HU时延迟7s开始扫描;利用MIP和VR方式重建CTA图像;对比不同参数和不同对比剂应用方式的CT血管成像图像质量。结果最佳的扫描与重建参数为准直64×0.6mm,螺距1.5,层厚1.0,重建间隔50%;最佳的对比剂应用方式为(浓度为370mgI/100ml)对比剂70ml、生理盐水50ml以4.0ml/s注射速度按先后顺序团注。结论选择合适的准直、螺距以保证适当的扫描速度,选择合适的对比剂浓度、用量和注射速度以保证血管内足够的对比剂峰值浓度及峰值持续时间,此二者是64层CT下肢动脉成像成功的关键。     

PET／CT检查的护理配合

对PET／CT检查的385例患者和169例健康体检者给予精心、科学的检查前、检查后护理，并注意自身的放射性防护。结果554例均检查顺利，医务人员近期血常规正常。     

Pulmonary Lophomonas blattarum infection in patients with kidney allograft transplantation

The aim of the study was to analyse the clinical manifestation and management of pulmonary Lophomonas blattarum infection in four allograft transplantation recipients retrospectively. Four patients with pulmonary L. blattarum infection were diagnosed by using Fiberoptic bronchoscopy (FOB) and bronchoalveolar lavage (BAL) examination. Their clinical manifestation and management are summarized. Four cases of pulmonary L. blattarum were found during the period from the second month to the third month after transplantation. Concurring infection by other pathogens was found in three of them. Common initial symptoms included fever (>38 degrees C) without cough and breathlessness. Lower lobe shadowing could be found on chest X-ray. Body temperature decreased to the normal range in three patients and to 37.5 degrees C in the other one, after intravenous injection of metronidazole and tapering immunosuppressant. Radiological examination confirmed improved health condition of the patients afterwards. Two patients received repeated FOB and only dead L. blattarum was found. Pulmonary L. blattarum infection in allograft transplant recipients carry relatively obscure initial symptoms. Possible L. blattarum infection needs to be screened in post-transplantation pulmonary infection patients with similar symptoms, especially in those who respond poorly to anti-infection treatment. Microscopic examination of BAL fluid can help to identify pulmonary L. blattarum infection and metronidazole is an ideal treatment choice.     

孕期宣教对孕妇影响的调查与分析

[目的]了解孕期宣教对孕妇在保健知识方面的需求性,孕期检查的必要性及心理健康状况、分娩方式选择方面的影响。[方法]采用自制问卷调查表对1500例孕妇进行调查,其中接受孕期宣教1000例,未接受孕期宣教500例。[结果]孕期宣教对孕妇在保健知识的需求性和孕期检查的必要性上,在心理健康状况和对分娩方式的选择上有显著影响(P<0.005)。[结论]开办孕妇学校对孕妇实施针对有效的孕期宣教和保健指导是必要的。     

腹腔镜下切口疝补片修补术的临床应用

目的 探讨腹腔镜下腹壁切口疝修补术的手术方法、安全性等问题。方法对2004年3月至2006年5月79例行腹腔镜下补片修补术治疗腹壁切口疝病人的临床资料进行分析。结果 78例（98．7％）手术成功，1例因腹腔内广泛粘连而中转开放修补。平均手术时间为88min，平均术后住院4．6d，18例（22．8％）病人术中发现有1个以上的隐匿性缺损。术后并发症：术后短期内修补区腹壁明显疼痛58例（73．4％）。腹壁缝合点较长时间疼痛6例（7．6％），浆液肿14例（17．7％），无手术死亡，1例术后出现肠瘘，经保守治疗好转，1例腰部切口疝的病人术后复发。结论 多数病人腹壁切口疝可以经腹腔镜行粘连松解及补片修补术，并可在术中发现其他隐性缺损，手术安全性较高。对腹腔内广泛粘连而影响操作器械进入及粘连分离者，应及时中转开腹手术。
