腰椎穿刺术后头痛与卧床时间的关系

目的探讨腰椎穿刺术后平卧时间30min、2h对头痛的影响。方法对794例具有腰椎穿刺术适应证而无禁忌证并排除有关因素的患者，随机分为30min组、2h组。分别观察术后头痛发生率。结果30min组头痛发生率为（8／460）1．74％，2h组为（7／334）2.10％，两组组间比较均无显著性差异（P〉0．05）。结论本研究说明腰穿后卧床时间长短（30min～2h），对腰穿后头痛的发生率无影响，可缩短至30min，没有必要卧床2h，更没有必要卧床4～6h。     

脑卒中后抑郁症相关心理社会因素的对照研究

目的 探讨脑卒中后抑郁症相关的心理社会因素,以指导心理干预,提高生活质量。方法 30例卒中后抑郁患者为研究组,42例卒中后无抑郁患者为对照组。以医学应对问卷、社会支持评定量表(SSRS)和Barthel指数(BI)为评定工具,对两组患者分别进行评定。结果研究组面对量表分显著低于对照组(P<0.05),而屈服量表分显著高于对照组(P<0.01)。研究组SSRS评分显著低于对照组(P<0.01)。两组BI评分差异无显著性(P>0.05)。结论 有针对性的心理教育性干预并加强社会支持可能对防治卒中后抑郁起重要作用。     

The molecular and clinical impact of hepatocyte growth factor, its receptor, activators, and inhibitors in wound healing

Wound healing involves a number of cellular and molecular events, many of which are controlled by soluble growth factors. In the process of healing, hepatocyte growth factor, a cytokine known to act as mitogen, motogen, and morphogen, has been postulated to play multiple roles during several stages of this complex biological process. Produced primarily by stromal fibroblasts, hepatocyte growth factor regulates angiogenesis, vascular permeability, cell migration, matrix deposition and degradation, and other biological processes. The current article discusses recent progress in understanding the multiple roles played by this growth factor in tissue repair.     

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。     

IIEF-5与NEVA检测在阴茎勃起功能障碍诊断中的意义

目的探讨应用国际勃起功能评分5(IIEF-5)问卷表结合夜间阴茎勃起测定系统(NEVA)筛选勃起功能障碍(ED)的可行性及意义。方法148例门诊ED病人,应用IIEF-5问卷表评分,再通过NEVA测定仪监测夜间阴茎勃起情况,次日数据输入主机回放并分析。结果93例为心理性ED;在19~69岁的5个年龄组中,重度ED的比例由11.8%到55.0%,NEVA中度异常者IIEF积分(12.98±2.58)分,NEVA重度异常者IIEF积分(7.32±1.04)分。结论NEVA能有效地鉴别心理性与器质性ED,IIEF-5评分值与NEVA检测阴茎勃起时血容量变化值有相关性。IIEF-5与NEVA检测结合,能提高诊断和评估ED的可靠性。     

剖宫产术后硬膜外血肿并发脊髓损伤病人的护理

我科于2004年1月救治1例因羊水栓塞引起硬膜外血肿导致脊髓损伤的病人,针对病人存在或潜在的功能障碍和并发症采取了有效的干预。随着现代医学的发展,更多的脊髓损伤(spinal cordinjury,SCI)病人可存活下来,但绝大部分人留有重度残疾,生活质量受到严重影响[1]。因此,对SCI病人康复期存在或潜在的功能障碍和并发症采取干预性护理措施,可预防和减少脊髓功能的进一步损害,尽可能在较短时间内使病人达到生活自理,对其重返社会具有重要意义[2]。1病例介绍病人,32岁,孕40周,2004年1月10日因妊娠高血压综合征收住入院。11日03:40因胎儿宫内窘迫…     

脾脏钝伤的CT诊断

本文回顾性分析了３２例脾脏钝伤ＣＴ平扫的表现；对脾损伤进行ＣＴ分类；指出腹腔积血和脾周血块（“哨兵血块征”）在诊断脾损伤方面的作用。ＣＴ平扫诊断钝性脾脏损伤是一种敏感、可靠的方法，可帮助外科医生制订治疗方案。ＣＴ平扫诊断钝性脾损伤的灵敏度为９４％，诊断正确率为９１％     

The effect of MS-818, a pyrimidine compound,on the regeneration of peripheral nerve fibers of mice after a crush injury

One of the pyrimidine compounds, 2-piperadino-6-methyl-5-oxo-5,6-dihydro(7H)pyrrolo[3,4-d]pyrimidine (MS-818), has neurotropic effects in vitro. Therefore, we studied the effect of MS-818 on the regeneration of the peroneal nerve in C57BL/6J mice after a crush injury. Two test groups, which received a daily intraperitoneal injection of 5 mg/kg or 10 mg/kg MS-818, respectively, were compared with controls, which received daily intraperitoneal injections of physiological saline, over a 14-day period. The maximum foot-width ratio (crushed side/uncrushed side) was obtained on days 1, 8 and 14 after the crush injury, and the various morphometric parameters were evaluated at both 5 and 10 mm distal to the proximal portion of the crush site. The significant effects of MS-818 included a larger maximum foot width (P<0.04) and a greater number of unmyelinated axons per nerve at both levels (P<0.003) in both test groups than in controls. MS-818 had no significant effects on body weight, the increase of total transverse fascicular area after the crush injury, the total number of myelinated fibers with their size distributions, or the number of nuclei of Schwann cells and macrophages. Therefore, we conclude that MS-818 promotes axonal sprouting and elongation after a crush injury in mice.

脑电监测（24小时）对头痛型癫痫的诊断意义

对６０例临床疑为头痛型痛痫的患者进行２４ｈ脑电监测。结果表明：２４ｈ脑电监测对痛痫特殊类型的检出率明显高于常规ＥＥＧ。在１４例（２３．３％）有痫样放电的患者中，出现痫样放电以睡眠期多于清醒期；且睡眠周期中以ＮＲＥＭⅠ，Ⅱ期最常见。对６例（１６．２％）反复阵发出现高波幅额中线θ节律而无痫性放电的患者亦应考虑头痛型癫痫的诊断。
