白细胞介素-8在哺乳动物生殖过程中的作用

白细胞介素-8(IL-8)作为中性粒细胞趋化因子和促血管生成因子,受到人们的重视。研究表明,IL-8促进卵细胞的发育、成熟,诱发排卵;在输卵管和子宫内膜的表达随月经周期而变化;参与胚泡着床和胚胎发育。本文综述IL-8在哺乳动物生殖过程中的重要作用。     

The distally based sural fasciomusculocutaneous flap for foot reconstruction.

Finding appropriate soft-tissue to cover a wound located over the middle or distal portion of the foot can be challenging. A distally based sural fasciomusculocutaneous flap including the sural nerve and a midline cuff of the gastrocnemius muscle can be used for this purpose. This flap is designed on the proximal third of the posterior calf and is nourished in a retrograde manner by the lower peroneal septocutaneous perforators, through the vascular axis of the sural nerve to the musculocutaneous perforators of the gastrocnemius muscle. Between October of 2002 and January of 2004, this flap was applied in nine individuals, including four diabetic patients. The skin defects all resulted from trauma, osteomyelitis or chronic ulcer, and combined with bone or tendon exposure. One flap developed distal necrosis. The other flaps survived fully and provided good contour. In our series, diabetes mellitus seemed not to compromise the vascularity of the flap. The distally based sural fasciomusculocutaneous flap is very useful for lower limb reconstruction, particularly for the foot, because of its long vascular pedicle and the availability of the skin portion of the proximal calf based on direct branches between the musculocutaneous perforators and the neurovascular axis of the sural nerve. This is an important variant of the sural neurocutaneous flap and it appears to be a good alternative to free flaps for resurfacing the foot.     

三磷酸腺苷结合盒运转体A1与颈动脉粥样硬化斑块的关系

目的 探讨三磷酸腺苷结合盒运转体A1(ATP binding cassette transporter A1,ABCA1)在人颈动脉粥样硬化斑块中的表达变化及作用机制.方法 收集24例人颈动脉粥样硬化斑块标本和10例肠系膜动脉标本(对照组),采用RT-PCR测定ABCA1 mRNA和视黄酸X受体α(RXRα)mRNA表达水平,并采用Western Blot检测ABCA1及RXRα的蛋白表达水平.24例人颈动脉粥样硬化斑块标本按病理分级,比较病理组织为Ⅲ级和Ⅰ级动脉粥样硬化组织间ABCA1 mRNA、RXRαmRNA表达水平及蛋白表达水平.结果 颈动脉粥样硬化斑块组的ABCA1 mRNA(0.79±0.04)和RXRα mRNA(0.73±0.04)表达与对照组相比上调,差异有统计学意义(P＜0.05);ABCA1 mRNA与RXRα mRNA增加水平相关(P＜0.05);颈动脉粥样硬化斑块的ABCA1蛋白表达(0.22±0.03)下调水平与对照组(0.53±0.03)相比差异有统计学意义(P＜0.05);Ⅲ级和Ⅰ级动脉硬化斑块ABCA1mRNA、RXRα mRNA及蛋白表达水平差异有统计学意义(P＜0.05).结论 ABCA1及RXRα蛋白表达水平下调可能是进展性动脉粥样硬化损害的关键因素.     

慢性阻塞性肺病患者营养与餐后低氧的关系

目的研究慢性阻塞性肺病(COPD)患者的营养状况与餐后低氧的关系.方法51例COPD急性加重期后的患者连续监测就餐前后SpO2,同时记录饮食情况并换算为各营养素的量.结果营养不良组COPD患者餐后SpO2低于餐前,降低幅度超过3%(P＜0.05),进餐时间相对延长,营养物质摄入减少.SpO2变化与单位体质量总热量的摄入呈负相关(P＜0.05).结论重度COPD患者的营养状况可能与患者进餐后发生的缺氧、低氧血症有关,在营养支持中应考虑采取适当措施干预就餐引起的相关低氧血症的发生.     

肠系膜缺血性疾病的临床诊断

早期诊断和及时治疗，对降低肠系膜缺血性疾病的并发症发生率和病死率至关重要，但由于肠系膜缺血性疾病缺乏特异的临床表现，鉴别诊断也比较困难。因此，基于临床表现的早期诊断一直是非常困难的课题。

Observations on the efficacy of combined acupuncture and medicine in Treating 50 cases of pseudobulbar paralysis

目的：观察针药结合治疗假性延髓麻痹的疗效。方法：采用完全随机抽样法分为针刺组50例，对照组48例。针刺组在西医治疗的同时，应用针刺进行综合治疗；对照组单纯接受西医药物治疗。结果：针刺组有效率为92．0％，对照组为62．5％。两组疗效差异具有非常显著性意义（P〈0．01）。结论：针药结合治疗假性延髓麻痹效果明显优于单纯西药治疗。     

自体输血在出血性手术中的应用

外科手术,特别是出血量较大的急诊手术、术中出血较多的心内直视手术、以及颅脑外科手术等用血量大,一直是医疗中棘手的问题,而随着人们对输血所带来并发症的重视,以及近年来血源不足及合理输血、血液保护等,使得自体输血成为主流。本文就自体输血在临床应用,特别是大出血性手术中的应用价值作一综述。     

Structural shielding design for a gamma ray stereotactic body radiotherapy system.

An OUR-QGD gamma ray stereotactic body radiotherapy system (body knife), made in China, is described. According to its structure and the principle of gamma radiation revolved on a focus, the energy distribution of scattered radiation in its treatment room is calculated. The structural shielding of the wall, roof, and door for a certain treatment room is calculated according to the local radiation protection law.     

The modified outside-in suture: vertical repair of the anterior horn of the meniscus after decompression of a large meniscal cyst

This article describes a modified suture technique designed for the vertical repair of the anterior horn of the meniscus after arthroscopic decompression of a large meniscal cyst. This procedure comprises of three steps: first, the meniscus was pierced vertically using a suture hook and a No. 0 PDS suture. Second, both ends of the No. 0 PDS on the femoral and tibial surfaces of the meniscus were pulled to the outside of the joint capsule using a spinal needle preloaded with suture material. Finally, a skin incision was made adjacent to the suture materials, and both ends were tied. We recommend this technique not only for the vertical repair of the anterior horn of the meniscus after decompression of large meniscal cyst, but also to repair a longitudinal tear of the meniscus.
