系统康复治疗对年轻肩关节脱位患者肩关节稳定性的作用

目的对年轻患者肩关节脱位进行系统的康复治疗,以检验系统康复疗法疗效优于单纯固定的假设。方法根据所采用的治疗方法,将43例40岁以下的急性肩关节脱位患者分成实验组23例,对照组20例。实验组患者进行包括关节活动范围锻炼、发展肩胛骨周围肌的肌力训练、发展肩袖肌的肌力、适度的外展、外旋锻炼及耐力训练在内的系统康复治疗。对照组只进行单纯固定后未经系统康复治疗。对两组患者的临床效果进行比较。结果实验组复发率为17%(4/23),对照组复发率为45%(9/20),两组复发率比较差异有显著性意义(χ2=3.866,P<0.05);随访结果显示肩关节ASES评分实验组为90.9±4.87,对照组为75.4±4.94,两组差异有非常显著性意义(t=9.94,P=2.99×10-12<0.01)。结论肩关节脱位年轻患者进行系统的康复锻炼,可以提高患肩的稳定性。     

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.

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。     

椎管扩大成形术治疗腰椎管狭窄

目的：探讨椎管扩大成形术治疗腰椎管狭窄的效果。方法：椎板减压后复位，用棘突或髂骨植于一侧开槽处扩大椎管，并进行椎板及关节突关节植骨，对54例随访病人的手术前后临床表现及X线和CT进行比较。结果：随访6—39个月，临床优良率为81．1％。随访X线片显示椎板明显后移，CT测量与术前对比显示椎管内径扩大明显。结论：椎管扩大成形术操作简单，效果满意，术后并发症少，是治疗腰椎管狭窄的又一选择。     

骨质疏松相关基因的研究进展

骨质疏松(osteoporosis,OP)在很大程度上受基因的影响。在OP的相关基因中,维生素D受体(VDR)基因、雌激素受体(ER)基因、Ⅰ型胶原基因及转化生长因子基因都是重要的候选基因。VDR基因中BB基因型者比Bb及bb基因型者的腰椎骨密度(bone mineral density,BMD)低,骨丢失率高。FokⅠ基因型与腰椎BMD降低有明显相关性,ff基因型者腰椎BMDXx基因型者>xx基因型者。Ⅰ型胶原基因与骨量呈显著相关性,COLIA1基因突变可致低骨量、骨脆性增加。转化生长因子β(TGF-β)基因对调节骨形成和骨吸收有重要作用,TGF-β基因中可发生碱基丢失,这种变异多见于OP患者。     

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。     

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.
