腹腔镜肝右后叶囊肿开窗引流术35例报告

目的：探讨肝右后叶肝囊肿的腹腔镜处理方法。方法：1998年1月～2005年12月对35例有症状的肝右后叶囊肿（21例主要位于Ⅵ段，14例主要位于第Ⅶ段）采用四孔法行囊肿开窗引流术。囊肿位于肝右后叶上段者采用肝上入路，胆囊牵引钳或三叶钳推压肝脏使其向前向下，暴露肝后囊肿，囊肿开窗，修剪带蒂大网膜放入囊肿。囊肿位于肝右后叶下段者采用肝下入路，超声刀切开肝结肠韧带，右三角韧带及肝肾间疏松组织，胆囊牵引钳抬起肝脏，囊肿开窗，大网膜放入囊腔引流。结果：35例肝右后叶肝囊肿均在腹腔镜下完成肝囊肿开窗引流术，无中转开腹手术。15例采用肝上入路，20例采用肝下入路。手术时间30～95min，平均46min。无手术并发症。35例病理检查结果均为先天性肝囊肿。术后症状均消失。术后住院2～5d，平均3．8d。35例随访6～36个月，平均34个月，33例无复发，2例（为肝上入路病例）囊肿未完全消失，但较术前明显缩小，无明显症状，观察半年未见增大。结论：肝下及肝上入路囊肿开窗引流是腹腔镜下处理肝右叶肝囊肿的有效方法。     

微波子宫内膜去除术与子宫切除术治疗异常子宫出血的疗效比较

目的 比较微波子宫内膜去除术(MEA)和子宫切除术(AH)治疗异常子宫出血的疗效.方法 将异常子宫出血80例分为MEA组和AH组各40例,比较两组临床疗效、手术时间、术中出血及手术前后白细胞变化. 结果 MEA和AH治疗异常子宫出血的有效率无显著差异(39/40 vs 40/40,χ2=0.000,P=1.000).MEA手术时间短[(4.8±1.2)min vs(102.5±34.6)min,t=17.848,P=0.000];术中出血少[0 ml vs(138.3±40.6)ml,t=21.544,P=0.000]. 结论 MEA是一种治疗异常子宫出血有效且微创的手术.     

Pathways from first health care seeking to diagnosis: obstacles to tuberculosis care in rural China.

OBJECTIVE: To examine health care seeking pathways for patients with tuberculosis (TB) and barriers related to these pathways in counties under the National TB Control Programme in rural China. METHODS: A cross-sectional study was conducted in two counties of east China in 2004-2005. A total of 557 TB patients were recruited and interviewed by physicians at the time of TB diagnosis. RESULTS: Of 557 participants, 13.3% had presented to a specialised county TB dispensary (CTD) directly after onset of symptoms, 31.4% had first sought care at a village health station and 51.2% had visited a township or county hospital first. The proportion of referral by a first health care provider to a CTD was highest in county level hospitals (73.5%) and lowest in village health stations (21.7%). The most prompt pathway from first health care seeking to TB diagnosis was to visit a CTD directly, with a median provider's delay of only one day. There was an increase in provider's delay when more health facilities were involved. CONCLUSION: To improve direct referral from general health care providers, especially village health care workers, to TB specialists would significantly shorten the delays in TB diagnosis in rural China.     

Late atrioventricular block after heart transplantation.

Bradyarrhythmia requiring permanent pacing after heart transplantation remains a common problem. Sinus node dysfunction is the most common indication, and late onset of atrioventricular (AV) block has rarely been reported. We report the case of a patient who developed advanced AV block at 41 months after transplantation. Right bundle branch block with progressive increase of QRS complex duration was noted in serial electrocardiograms. At the time of late AV block development, the patient did not have acute rejection and coronary angiogram was normal. The mechanism of late onset of AV block is unclear, but it may be caused by progressive conduction.     

64排螺旋CT冠状动脉造影与DSA的对照研究

目的:通过和冠脉造影对比,评价64排螺旋CT冠状动脉成像在冠状动脉狭窄中的临床应用价值。方法:28例患者同时行64排螺旋CT冠状动脉成像和有创性冠脉造影检查,依据AHA17段分段法,评价所有有效节段,并将两者进行对比。结果:冠脉造影显示阴性病例占7.1%(2例),单只病变占21.4%(6例),多支病变占71.4%(20例)。按节段分析,CT检出冠脉狭窄的敏感度,特异度,阳性预测值和阴性预测值分别为91.1%,94.6%,90.0和95.3%。结论:64排螺旋CT冠状动脉成像和传统的冠脉造影检查对检出正常冠脉节段以及狭窄节段具有很好的一致性。

本文报道青霉素配伍利多卡因后的药物动力学及生物利用度研究结果,证明利多卡因对青霉素的生物利用度无影响,且可促进青霉素的吸收,为良好的青霉素无痛溶媒,建议推广使用。     

某儿童医院10年临床报告细菌性痢疾的流行病学特征

目的探讨细菌性痢疾(以下简称菌痢)近10年流行特点。方法对10年来收集的全院各科上报的菌痢进行回顾性分析。结果1993-2002年报告菌痢10861例,占传染病报告总数的62.92%,传染科门诊量占全院门诊百分比的年变化为8.54%～4.33%;菌痢发病占传染科门诊的年比率变化为1.05%～3.45%;<1岁、1～3岁、4～6岁、7～9岁、≥10岁5个年龄组,各组之间菌痢检出率差异有统计学意义,1～3岁组检出率最高;细菌性痢疾每年4月检出率开始上升,8月达最高,11月检出率恢复到上升前水平;不同性别的儿童检出率差异有统计学意义,男童明显高于女童。结论细菌性痢疾检出年龄特点为婴幼儿最高,随年龄增长,发病逐渐减少;发病高峰季节向春秋季扩展。     

利福喷汀治疗耐利福平肺结核的疗效分析

目的分析增加利福喷汀的用药剂量对利福平耐药肺结核的疗效，以评价利福喷汀在治疗利福平耐药患者中的作用。方法根据药敏结果选取耐利福平肺结核患者101例，分为治疗1组（利福平低耐），治疗2组（利福平高耐），两组治疗方案中均含利福喷汀，对照组（利福平高耐）治疗方案中不合利福喷汀。观察治疗后3、18个月疗效。结果治疗1组在各阶段的痰菌阴转率、病灶吸收和空洞闭和情况明显优于治疗2组和对照组，两组差异有统计学意义；治疗2组的痰菌阴转率、病灶吸收和空洞闭和情况略优于对照组，两者差异无统计学意义。结论对利福平耐药的患者尤其在利福平低度耐药病例中，可以选择增加利福喷汀用药剂量的方案进行治疗，在利福平高度耐药病例中利福喷汀的作用不能确定。
