利用CO_2培养箱敞开式不换液羊水细胞培养方法的改进

本文对羊水培养方法进行了改进研究,探讨了培养液 pH 值对羊水细胞生长的影响。结果表明用 CO_2培养箱敞开培养,在 CO_2浓度为5.4%时羊水细胞最容易贴壁生长,一次性加液中间不换液可保持细胞生长的微环境稳定,是羊水细胞培养成功的关键。     

白细胞介素—2胸腔灌注治疗恶性胸水24例临床分析

恶性胸腔积液能严重影响病人的呼吸循环功能,加速病人死亡。本文对24例恶性胸腔积液病人给予白细胞介素—2(IL-2)胸腔灌注治疗,取得了明显效果。其总有效率(完全缓解率 部分缓解率)较对照组有显著性差异(P<0.05),该作者认为该疗法治疗效果肯定,副作用轻,具有推广应用价值。     

肠梗阻的临床进展

将近5年来有关肠梗阻的新诊治方法作一综述，结论如下：①B超、CT和76％泛影葡胺口服造影等对肠梗阻诊断有重要临床价值。②腹腔镜小肠梗阻手术是最能体现微创技术优越性的手术之一。③EPII应以非手术疗法为主。     

Localized cerebral proton MR spectroscopy in HIV infection and AIDS.

PURPOSETo document differences in the cerebral proton MR spectra of patients with early and late stages of human immunodeficiency virus (HIV) infection.METHODWe studied the relative N-acetyl-aspartate (NAA) levels by localized proton spectroscopy of the parietooccipital region of the brain in 43 HIV-seropositive patients, including 26 with an acquired immunodeficiency syndrome (AIDS)-defining diagnosis, and in eight control subjects.RESULTSReduced relative NAA levels were shown in those HIV-1-seropositive patients: 1) with AIDS against HIV-1-seropositive patients without AIDS (P < .04); 2) with HIV-1-associated cognitive/motor complex against neurologically healthy patients (P < .007); 3) with encephalopathic changes on MR against those with normal imaging (P < .001); and 4) on follow-up against their results on initial study (P < .03).CONCLUSIONSBy clinical (Centers for Disease Control classification) and radiologic (MR evidence of white-matter disease) criteria indicating late-stage HIV infection, reduced relative levels of NAA have been demonstrated. Spectroscopic abnormalities can be quantitatively tracked with time. This paper demonstrates the clinical use of detecting NAA as a putative in vivo measure of the neuronal loss that has been demonstrated in postmortem studies of patients with AIDS. This neuronal loss, which is believed to underlie the HIV-1-associated cognitive/motor complex, is thought to be attributable directly or indirectly to the presence of HIV in the brain. Proton spectroscopy may serve as a quantitative noninvasive indicator of this aspect of cerebral involvement in HIV disease.     

不同膳食特点地区中老年人血红蛋白及其与膳食营养的关系

测定分析不同膳食特点地区975例年龄45～74岁中老年人的血红蛋白及其与膳食营养素的关系。结果牧民及城市居民贫血率低，北京及新疆托里分别为7.6％和4.6％。男性比女性血红蛋白高，血红蛋白随年龄增加而降低。相关分析结果血红蛋白与膳食热能、蛋白质、动物蛋白质与总蛋白质比值呈显著正相关。结果说明血红蛋白可用于中老年人营养状态监测。

Arthroscopic all-inside repair techniques of lateral meniscus anterior horn tear: a technical note

Although the conventional outside-in technique is especially useful for repairing tears in the anterior portion of the meniscus, it has a disadvantage of making an additional 1–2 cm sized skin incision and tying knots subcutaneously over the capsule. Therefore we devised two all-inside repair techniques of lateral meniscus anterior horn tear according to the site of meniscal tear, meniscosynovial junction or red–red zone. Because these techniques are modified methods of the outside-in meniscal repair using a spinal needle, they are as simple as conventional outside-in technique. In addition they have advantages of vertical mattress suture, which is an important characteristic of the all-inside repair, and no additional incision. We recommend these techniques as an alternative method for repairing an anterior horn tear of the lateral meniscus.     

外科围手术期糖尿病的治疗

目的:探讨外科手术病人伴发糖尿病的治疗及围手术期处理。方法:对1998年至2000年收治的125例外科手术伴发糖尿病病例进行回顾总结。结果:93例给予补液、降糖等处理无1例死亡。其他32例未进行有效的降糖处理,死亡5例。结论:外科手术病人伴发糖尿病时,围手术期要控制血糖,可以降低手术并发症及死亡率。     

臀上血管深上支的应用解剖

本文观察了52侧(男46,女6)成人尸体臀上动、静脉深上支进入髂嵴情况.臀上动、静脉深上支分为前、中、后支;本文测量了臀上动、静脉深上支的外径及各分支进入髂嵴的距离.臀上动、静脉深上支的分支在髂嵴前部及中部分布较多,前支的分支为3～8支,其中以4～6支者为多见,占78.8±5.5％;中支的分支1～4支,其中以2～3者为多见,占73.1±6.1％.因此,臀上动脉深上支作为游离髂骨移植术取髂嵴的前部和中部较宜.     

神经活素对Pc12细胞作用的初步观察

从胎脑、颌下腺、肌肉组织中制备神经活素。其性能同脑活素一样：可促进Ｐｃ１２细胞的突起生长，提高其胞浆内乳酸脱氢酶活性，电泳显示二者有相同的三条带。提示：神经活素有可能替代脑活素应用于临床。
