妇科腹腔镜手术中转开腹22例原因分析

目的 探讨妇科腹腔镜手术中转开腹的原因及从中吸取的经验。方法 回顾分析2004年6月-2007年6月我院982例妇科腹腔镜手术中中转开腹22例的临床资料。结果 腹腔镜中转开腹率为2．24％，22例中转开腹的原因及其所占的比例依次为：盆腔粘连6例（27．27％），子宫肌瘤部位特殊3例（13．64％），并发症3例（13．64％），卵巢恶性肿瘤3例（13．64％），术中出血3例（13．64％），官角妊娠2例（9．09％），盆腔肿瘤来源于肠道者2例（9．09％）。结论 术者手术技巧是手术中转开腹原因之一，要提高手术操作技巧；明确术前诊断，充分估计手术难度，可以减少腹腔镜手术中转开腹率；遇到困难，适时开腹可以减少手术并发症。     

In vitro evaluation of ablation parameters of normal and fibrous aorta using smooth excimer laser coronary angioplasty

A modified exeimer laser energy delivery system was used to irradiate 100 segments of normal and fibrous aorta in vitro. The laser beam was scanned into 8 fiber bundles consisting of 50 fibers each resulting in a reduction of the applied pulse energy. The total repetition rate was increased to 150 Hz in order to keep the repetition rate per fiber bundle close to 20 Hz and to minimize thermal injury. The results demonstrate that effective ablation (etch rate per 8 pulses > 2.0 μm) occurred at an energy fluency of 50 mJ/mm² in both normal and fibrous aorta. Tissue damage (carbonization, tissue separation, fissures, cracks, and vacuolization) was in a range of 100 ± 28 to 152 ± 30 μm for normal aorta and in a range of 57 ± 35 to 110 ± 39 μm for fibrous aorta. We conclude that effective ablation of normal and fibrous human aorta can be achieved by the application of smooth excimer laser coronary angioplasty. This improvement of excimer laser technology may result in a reduction of shock wave- and cavitation-induced damage leading to a reduction of tissue injury. However, this awaits further in vitro and in vivo confirmation. © 1993 Wiley-Liss, Inc.     

单克隆抗体在淋巴细胞白血病中的临床应用

本实验应用二十一种抗人白细胞分化抗原的单克隆抗体。通过ABC(avidin-biotin peroxidase complex)免疫酶标方法对十二例淋巴细胞白血病病人进行了免疫表型分析。提示单克隆抗体在淋巴细胞白血病病人的临床分型、治疗及预后估计上很有意义。粒、淋双表达白血病其本质不明,因而治疗上至今还没有一个理想的方案。     

现代化医院呼唤现代服务模式

当前我们正在向建设基本现代化医院迈进,在注意硬件建设的同时,不要忽略软件建设。硬件建设需要大量投入,较易见成果;而后者无需大量财力投入,只需转变医院人的思想观念,就能使医院明显改观。     

抗性家蝇蛹期多肽的双向电泳分析

分析抗性家蝇蛹期多肽，以了解蛋白质变化情况。方法：对家蝇的抗性株、对照株和敏感株蛹体内的多肽进行了聚丙烯酸胺凝胶电泳分析。结果：抗性株具有一特异的多肽点，且有3个多肽点在量上明显多于对照株。结论：杀虫剂的作用可使抗性家蝇体内的蛋白在质和量上发生改变。     

费氏艾美尔球虫（E.ferrisi）某些生物学特性的研究

采用从自然感染球虫的小鼠粪便中分离的单卵囊接种小鼠获得成功，观察了此种球虫的卵囊形态，孢子化时间，潜隐期和寄生部位等，确定此球虫为费氏艾美尔球虫。为进行费氏艾美尔球虫病的流行病学调查和防治提供了依据。     

尿毒症患者血透中血液动力学监测

目的：观察尿毒症患者血透过程中血液动力学改变，方法：尿毒症患者20例，均在透析放血前，放血后，30min,60min,120min,180min，回血前，回因后测定血压，脉搏，中心静脉压，平均直接动脉压，结果：透析过程中血压，脉搏以及直接平均动脉压较稳定，中心静脉压放血前较正常为高，且高于血透过程中其它时间段（P＜0．05），结论：血透过程中血液动力学稳定，且中心静脉压的变化有利于心功能的改善。     

肿瘤患者医院感染的分析与预防措施

目的了解肿瘤科医院感染特点,为临床减少肿瘤患者感染提供参考信息。方法以主动监测与系统回顾相结合的方法,对2005年全年入住肿瘤科2 679例患者的临床资料进行统计、分析、评定。结果2 679例肿瘤患者发生医院感染120例次,医院例次感染率为4.47%,其中感染1次者179例、2次者31例、≥3次者10例;以呼吸道感染占首位,其中上呼吸道38例、下呼吸道36例,其次为消化道10例、血液9例、手术切口感染8例、泌尿道6例和其他部位感染13例。结论提高机体免疫力、控制内源性感染,是预防与控制肿瘤患者感染的主要措施。     

Anatomic and spiral computed tomographic study of the genial tubercles for genioglossus advancement.

OBJECTIVE: To measure and compare Chinese mandibular genial tubercles measured anatomically and with computed tomography (CT). STUDY DESIGN AND SETTING: Spiral CT scans were taken of 40 adult human skulls; the superior genial spines were measured using anatomic and CT methods. RESULTS: The height and width of the superior genial spines, mandible thickness, and distance from the menton to the inferior and superior margins of the superior genial spines were 5.82 +/- 0.71, 6.98 +/- 1.35, 11.95 +/- 1.59, 11.08 +/- 2.05, and 16.91 +/- 2.30 mm from anatomic measurements and 6.17 +/- 0.71, 7.01 +/- 1.13, 12.19 +/- 1.64, 10.41 +/- 1.55, and 15.73 +/- 2.12 mm using spiral CT, respectively. The anatomic and CT measurements were correlated. CONCLUSION: Spiral CT of the genial tubercles can help locate the osteotomy in genioglossus advancement. SIGNIFICANCE: This study acquired reference data on Chinese genial tubercles demonstrating that CT measurements of the genial tubercles reflect their anatomy, which should allow accurately locate the osteotomy.
