血管内栓塞结合显微手术治疗颅内动脉瘤临床研究

目的应用显微手术夹闭、血管内栓塞和栓塞后手术夹闭3种治疗方法，探讨治疗颅内破裂动脉瘤的安全有效方案。方法显微手术瘤颈夹闭30个动脉瘤，栓塞34个动脉瘤，栓塞后夹闭15个动脉瘤。结果夹闭组30个完全夹闭，无复发，死亡率6％（2／30）。栓塞组完全闭塞率70．6％（24／34），复发率17．6％（6／34），死亡率11．8％（4／34）。栓塞后手术组15个完全夹闭，无复发，死亡率6．7％（1／15）。治疗结束用GOS评价，1个月后3组良好率分别为80．0％、79．4％和80．0％；半年后良好率分别为90．0％、88．2％和86．7％。结论显微手术瘤颈夹闭术仍然是治疗破裂动脉瘤的有效方法，具有1次治疗彻底和复发率低的优势，并可作为栓塞失败的补救手段。

547例垂体腺瘤延迟诊断原因及影像诊断分析

目的:提高垂体腺瘤特别是微腺瘤早期影像诊断率。方法:通过对所搜集病史资料完整,经医学影像学确诊和手术病理证实的547例垂体腺瘤(内有251例微腺瘤)延迟诊断原因的分析,找到影响垂体腺瘤早期诊断的因素。结果:296例垂体大腺瘤蝶鞍X线平片、CT、MR常规检查即可诊断。CT骨窗蝶鞍片有助于垂体微腺瘤的诊断,251例微腺瘤经高分辨力CT薄层冠状强化扫描和高场强MR薄层强化扫描得以明确诊断。结论:熟悉垂体腺瘤的首发症状,及时行CT、MR常规扫描可明确大腺瘤的诊断,CT骨窗片可发现垂体微腺瘤的佐证。高场强MR薄层强化扫描是目前诊断垂体微腺瘤的最佳方法,高分辨力CT冠状薄层强化扫描次之,结合神经内分泌学检查是提高垂体腺瘤影像学早期诊断率的主要措施。     

对诊断PADAM的游离睾酮指数的评估

目的 评价诊断中老年男子部分雄激素缺乏综合征（PADAM）的游离睾酮指数（FTI）.方法 对129例45岁以上健康男性的FTI进行年龄相关分析.以推算的游离睾酮（CFT）值为依据,对FTI进行有效性检验.结果 男子在中老年期FTI与增龄呈明显的负相关.FTI敏感性97.78%,特异性58.33%.结论 计算简单的FTI可用于PADAM病人的筛选和随访,尤其对70岁以上男子是血清FT较为有效的参数.     

2004年聊城市东昌府区2类食品卫生质量抽检结果分析

[目的]了解东昌府区糕点、面包类与饼干类食品的卫生质量状况。[方法]对2004年在东昌府区城区及周边16个乡镇采集的糕点、面包类和饼干类样品检测资料进行分析。[结果]检测样品1 180份,合格率为84.41%。其中,糕点、面包类样品合格率为83.35%,城区合格率高于乡镇,生产加工单位合格率高于销售单位(P<0.01);饼干类样品合格率为87.30%,城区与乡镇、生产加工单位与销售单位样品的差异无统计学意义(P>0.05)。不合格项目是菌落总数、大肠菌群、酸价和过氧化值。[结论]饼干类的合格率较高,糕点、面包类的合格率较低;销售单位糕点、面包类的卫生质量较差,乡镇样品的卫生问题较为突出。     

Reversal of vascular 18F-FDG uptake with plasma high-density lipoprotein elevation by atherogenic risk reduction

Vascular 18F-FDG uptake marker represents inflammation in atherosclerotic lesions, but whether inflammation can be reversed by risk-modifying interventions has not, to our knowledge, been demonstrated. In this study, we evaluated the change of vascular 18F-FDG uptake in response to lifestyle intervention on serial PET/CT scans and further assessed how the findings relate to atherogenic risk reduction. METHODS: A total of 60 healthy adults underwent 18F-FDG PET/CT scans and atherogenic risk-factor assessment at baseline and again after 17.1 +/- 8.3 mo of practicing lifestyle modification. The PET/CT images were evaluated for the presence of vascular 18F-FDG lesions, and vessel-to-blood-pool 18F-FDG ratios were measured. Indices from summed ratios of positive lesions were compared and correlated to atherogenic risk factors. RESULTS: At follow-up, significant reductions in diastolic blood pressure (P < 0.05), total cholesterol (P < 0.05), and low-density lipoprotein level (P < 0.05) and an increase in high-density lipoprotein (HDL) level (P < 0.0001) were demonstrated. On the initial PET/CT scan, 50 of 60 subjects showed 1 or more 18F-FDG-positive lesions (5.9 +/- 5.0/subject), leading to a total of 352 vascular sites. On follow-up, 18F-FDG-positive lesions were significantly reduced to 2.1 +/- 2.2 sites per subject (P < 0.0001) and a total of 124 sites (64.8% reduction). Follow-up 18F-FDG-positive rates were significantly reduced for the aorta and iliac arteries. In addition, significant reductions in the whole-body 18F-FDG index from 1.39 +/- 1.23 to 0.53 +/- 0.59 (P < 0.0001) and carotid 18F-FDG index from 0.08 +/- 0.16 to 0.03 +/- 0.06 (P = 0.01) were shown. The whole-body 18F-FDG index correlated with total cholesterol (P < 0.05) and HDL level (P < 0.05), and the magnitude of reduction in the 18F-FDG index closely correlated to the amount of increase in plasma HDL level (P = 0.005). CONCLUSION: Our study demonstrated that vascular 18F-FDG uptake is reversed in response to atherogenic risk reduction by lifestyle intervention and that the magnitude of improvement correlates to increases in plasma HDL levels. Thus, serial 18F-FDG PET/CT may be useful for monitoring improvements in the inflammatory component of atherosclerotic lesions in response to risk modification.     

化疗药物对轴型皮瓣血运影响的组织学观察

目的探讨抗癌药物动脉灌注后对局部轴型皮瓣血运影响的组织学评价。方法在猪腹部的腹壁上动脉插管灌注抗癌药物,10d后在猪腹部形成以腹壁上血管为蒂的岛状皮瓣,通过对灌注区域轴型血管供养的岛状皮瓣的成活率、光镜、透射电镜及血管铸型透明标本的组织学观察,显示其血管结构及构筑的变化。结果抗癌药物用于局部动脉灌注后,使局部轴型血管支配的血管网有损伤的表现,岛状皮瓣远端的血运显著降低。结论抗癌药物经动脉灌注后可影响局部轴型皮瓣的血运,使皮瓣血供的安全范围缩小,为提高相关修复手术的成功率提供可靠的科学依据。
