多普勒组织成像技术在评价高血压左室舒张功能中的应用

目的 :应用多普勒组织成像 (DTI)技术检测二尖瓣环舒张期运动速度来评介原发性高血压左室舒张功能 ,探讨DTI的临床应用价值。方法 :2 0例原发性高血压和 2 0例年龄相似的健康者 ,应用DTI技术对二尖瓣环室间隔侧的运动速度进行测定 ,并与常规二尖瓣血流脉冲多普勒 (PW)检测结果对照分析。结果 :PW高血压组与对照组比较 ,峰值速度E、A及E/A明显低于对照组 ,差异显著 (P <0 0 1) ;DTI高血压组与对照组比较 ,峰值速度Ea、Aa及Ea/Aa明显低于对照组 ,差异非常显著 (P <0 0 0 1)。PW、DTI两组相同部位间比较 ,高血压组低于对照组。结论 :DTI技术评价高血压左室舒张功能比常规脉冲多普勒二尖瓣血流参数更敏感

顺铂聚乳酸微球的药物释放特性及肝动脉栓塞研究

对顺铂聚乳酸微球进行了体外药物释放和家犬肝动脉栓塞研究。该微球粒径范围为50～200μm,平均粒径为115.76±35.94μm,顺铂含量为37.16%(W/W);体外药物释放机制符合Higuchi方程;肝动脉栓塞后8h,肝组织顺铂浓度高达21.55±12.18μg/g,明显高于肝动脉灌注顺铂组:3.16±0.09μg/g(P<0.05);肝动脉栓塞组的顺铂血浓峰值、各取血点浓度及曲线下面积AUC皆低于肝动脉灌注顺铂组。可望达到提高栓塞部位的药物疗效,降低全身毒副反应的作用。

Integrating PET and CT information to improve diagnostic accuracy for lung nodules: A semiautomatic computer-aided method.

Our objective was to develop and evaluate 3 semiautomatic computer-aided diagnostic (CAD) schemes for distinguishing between benign and malignant pulmonary nodules by use of features extracted from CT, 18F-FDG PET, and both CT and 18F-FDG PET. METHODS: We retrospectively collected 92 consecutive cases of pulmonary nodules (<3 cm) in patients who underwent both thoracic CT and whole-body PET/CT. Forty-two of the nodules were malignant and 50 benign, as confirmed by pathologic examination and clinical follow-up. The interval between CT and PET was less than 1 mo. Four clinical parameters, including patient age, sex, smoking status, and history of previous malignancy, were used for the CAD schemes. Sixteen CT features based on size, shape, margin, and internal structure of nodules were independently rated subjectively by 2 chest radiologists. Four PET features were viewed on a PET/CT workstation. CAD schemes based on clinical parameters together with CT features, PET features, and both CT and PET features were then used to differentiate benign from malignant nodules. Finally, the output from the CAD schemes was evaluated by use of receiver-operating-characteristic analysis. RESULTS: When we used clinical parameters and CT features as input units (CAD scheme 1), the area under the receiver-operating-characteristic curve (A(z) value) of the CAD scheme was 0.83. When we used clinical parameters and PET features as input units (CAD scheme 2), the A(z) value for the computer output was 0.91. However, when we used all data as input units (CAD scheme 3), the A(z) value for the computer output was 0.95. The performance of CAD scheme 3 was better than that of CAD scheme 1 or 2. A statistically significant difference existed between the A(z) values of CAD schemes 3 and 2 (P = 0.037) and between those of CAD schemes 3 and 1 (P = 0.015). CONCLUSION: Our CAD scheme based on both PET and CT was better able to differentiate benign from malignant pulmonary nodules than were the CAD schemes based on PET alone and CT alone.     

硬膜外穿刺针外套管在腹腔镜小儿斜疝高位结扎术中的应用

目的探讨硬膜外穿刺针外套管在腹腔镜小儿斜疝疝囊高位结扎中的应用价值。方法2003年4月-2006年5月,我院对230例小儿斜疝手术应用硬膜外穿刺针外套管代替雪橇钩针实施腹腔镜疝内环口荷包高位结扎术。结果230例手术均获得成功,手术时间：单侧161例8-10 min,嵌顿疝39例15-20 min,双侧30例16-20 min;术后未见有阴囊水肿及睾血疼痛及缺血坏死。术后随访2-6个月111例,6-12个月52例,12-24个月37例,24-36个月30例,无复发。结论硬膜外刺针外套管可替代小儿疝囊结扎专用的雪橇钩针,简便,经济,适合在所有基层医院推广。     

腹腔镜、胆道镜联合治疗胆总管结石的临床研究

目的：探讨腹腔镜胆道镜胆总管探查取石的可行性、安全性及适应证。方法：对比分析腹腔镜手术组（n=20）与开腹手术组（n=20例）胆总管探查取石术的手术时间、术中出血量、术后排气时间、住院天数、术后疼痛、并发症发生率等。结果：腹腔手术组与开腹手术组手术时间分别为（133.65±16.71）min、（89.8±11.02）min,术后止痛剂使用率分别为20%、85%,术后排气时间分别为（31.15±4.98）h、（56.65±13.45）h,住院时间分别为（8.55±2.11）d、（14.95±2.96）d。以上项目两组均有统计学差异（P〈0.01）;并发症发生率分别为10%、25%,无明显差异（P〉0.05）。结论：腹腔镜联合胆道镜胆总管切开取石术安全可靠,手术创伤小,值得临床推广。
