移植人羊膜细胞对大鼠创伤性脑损伤的实验研究

目的 探究大鼠TBI后脑内移植人羊膜细胞（HACs）对大鼠运动功能的影响。方法 HACs经分离、Hoechst33342标记后重悬调整细胞浓度为10^5/μl；采用改进的Feeney自由落体法打击大鼠脑皮层后肢运动区域，损伤后24h经微量注射器和立体定向仪将Hoechst33342标记的HACs 10μl分别移植于挫伤灶中心和挫伤灶边缘；在TBI后的28d内采用钉板平衡木行走测试大鼠运动功能变化，运动功能检测结束后取出脑组织行组织学检测。结果 治疗组滑落脚步数明显少于对照组（P〈0．05）；移植的HACs呈蓝色荧光；部分移植HACs可见MAP-2阳性表达。结论 移植HACs使大鼠TBI后运动功能明显改善。     

创伤性休克的液体超负荷分析

目的 探讨创伤性休克患者发生液体超负荷的原因和治疗方法。方法 总结存活时间超过24h的286例创伤性休克患者，对休克纠正后出现全身性水肿患者进行分析，比较存活与死亡患者在伤后第1～8天的液体出入量。结果 286例创伤性休克患者中，出现水肿者262例（91．6％），存活232例（88．5％），死亡30例（11．5％）。死亡组的液体入量明显多于存活组（P〈0．05），液体出量则显著少于存活组（P〈0．05或P〈0．01）。存活组在伤后第4、5天出现液体负平衡即液体出量大于液体入量600～700mL（P〈0．05），而死亡组未出现液体负平衡现象。结论 创伤性休克的抢救过程中容易造成液体超负荷，液体出量增加甚至出现液体负平衡现象，预示着病情好转，此时只要生命体征稳定即可，不宜过分强调出入量平衡而大量补充液体。     

大鼠脑损伤局部谷氨酸的异常释放对乳酸含量变化的影响

目的探讨谷氨酸(Glu)在大鼠脑损伤局部的异常释放以及其对乳酸(Lac)含量变化的影响。方法采用大鼠局部脑损伤动物模型,分为对照组、损伤组、干预组。伤前15min干预组注射Riluzole(一种Glu突触前释放抑制剂),损伤组注射等容量的生理盐水,对照组仅开骨窗不损伤脑。应用微透析技术检测各组伤后不同时间透析液中Glu含量([Glu]d)及Lac含量([Lac]d)变化。结果[Glu]d及[Lac]d在伤后15min、30min和45min干预组明显低于损伤组(P<0.05),而明显高于对照组(P<0.05);在伤后60min,损伤组仍明显高于对照组(P<0.05)。伤后不同时间[Glu]d和[Lac]d变化呈显著正相关(P<0.01)。结论脑损伤后受损脑组织细胞液中Glu水平的升高是Glu神经元末梢大量释放Glu所致,并继而引起了Lac的含量升高。     

创伤性休克病人的早期急救护理体会

目的:讨论在院前和急诊科对创伤性休克病人施行早期急救护理,对挽救病人的生命及伤情预后有重要的意义.方法:对我科1997年2月至2001年4月27例创伤性休克病人进行早期,快速,积极的补液,输血增加有效循环量,监测生命体征等综合性抢救治疗与护理措施.结果:经早期积极急救护理,26例病人收缩压维持在60mmHg以上,意识清醒,脉搏有力,转入手术室或专科治疗,1例病人伤势严重抢救无效死亡.结论:创伤性休克病人,伤势复杂,死亡率高,伤后早期院前与急诊科的有效救护,是提高抢救成功率的关键.     

Short term correlates of the Neuro Emotional Technique for cancer-related traumatic stress symptoms: A pilot case series

Introduction As many as one quarter of all cancer survivors report traumatic stress symptoms from cancer-related experiences. While the majority of these patients do not meet the criteria for posttraumatic stress disorder (PTSD), there is growing evidence that subsyndromal symptoms can significantly contribute to functional impairment and negative health outcomes. Treatment options for the hallmark symptoms of traumatic stress—unpleasant, intrusive thoughts and avoidant behaviors—have not been well investigated for the cancer survivorship population. Materials and methods Seven female cancer survivors with traumatic stress symptoms from cancer-related experiences and no other major psychopathology, were enrolled to receive three sessions of Neuro-Emotional Technique (NET), a brief, targeted treatment that combines traditional desensitization principles with complementary modalities. Results Psychological outcome measures (Impact of Event Scale (IES) and Subjective Units of Distress (SUD) and physiological measures (Heart Rate (HR) and Skin Conductance Level (SCL) demonstrated the following changes: 71% on IES, 88% SUD, 74% on HR, and 65% on SCL following the intervention. Statistically significant changes were observed for all four parameters, and effect size g for proportion improved were 0.50 each for IES, SUD, and HR, and 0.20 for SCL. Conclusions These cases suggest feasibility of the NET intervention for cancer-related traumatic stress and the potential for change in symptoms and physiological reactivity. Further investigation is needed to determine the specific and long-term effects of such an approach. Implications for cancer survivors Traumatic stress from cancer-related experiences might represent a constellation of symptoms that are amenable to brief, targeted interventions.

Mammaplasty: Shape,volume, and scar size

Recently many mammaplasty techniques have been presented with special attention paid to the resulting scar's size and its position. The surgeon should try to hid the scar, and if the inverted T incision is used, its horizontal branch should be as short as possible and kept in the breast area. Neverthelss, excessive concern about the final scar size should not interfere with the final results of the mammaplasty as far as shape, volume and lasting results are concerned. The author presents his experience in mammaplasty with respect to the volume, the shape, and the scar size interrelationships.     

1987年石家庄市结核病流行病学抽样调查

对石家市结核病的流行情况进行了随机抽样调查,共抽取24个调查点(市区8个、郊县16个)35745人。调查结果:平均患病率及菌阳患病率为0.63％和1.27％,其中郊县与市区分别为0.67％和0.54％及1.60‰和0.42‰(Ρ<0.01);15岁以下儿童有卡痕者,其结素反应阳性率年龄曲线,在7岁和12岁表现为低谷;1～3岁卡痕检出率,市区与郊县分别为90.5％与35.4％(Ρ<0.01)。通过本调查表明,我市结核病患病率高于全国1985年调查的平均数值。     

Sources of P300 attenuation after head injury: Single-trial amplitude, latency jitter, and EEG power

Single trial amplitude, latency jitter, and electroencephalographic (EEG) power were examined as sources of the group difference in averaged P300 amplitude among 15 traumatically brain injured and 20 control individuals in an auditory oddball paradigm. Mean amplitude of the individual trials was highly correlated with the amplitude of the averaged P300, with little additional unique variance attributable to latency jitter or EEG power. The group difference in P300 amplitude was also explained by the mean amplitude of the single trials. These results support the robustness of the event-related potential averaging technique within the paradigm used.     

Congenital healed cleft lip

Congenital “healed” cleft lip (CHCL) is an unusual anomaly including a paramedian “scar” of the upper lip, which appears as if a typical cleft lip has been corrected in utero. The CHCL is frequently associated with an ipsilateral notch in the vermilion, and “collapsed” nostril. Twenty-five CHCL cases are presented, eighteen of which were an isolated malformation found among the 3,950,715 births examined in two similar birth defect registries: ECEMC in Spain and ECLAMC in Latin America. Like open cleft lip, of which it seems to be a variant, CHCL is most frequently seen among males (14/18 isolated cases), it preferentially affects the left side (10/18 cases), and it segregated together with cleft lip in one family. The five CHCL cases with other congenital anomalies included: two cases with hydrocephalus, two VACTERL associations, and one atypical oblique facial cleft infant with single umbilical artery. CHCL may result from a defective fusion of the frontonasal and maxillary processes (before week 7 of embryonic life), or from a spontaneously repaired open cleft lip, later on. In either way, these cases heal with a visible scar, and the pre-occurrence of CHCL in two families suggests a familial predisposition to this phenomenon. © 1995 Wiley-Liss, Inc.
