368例0～5岁婴幼儿骨源性碱性磷酸酶活性测定结果分析

目的：探讨骨源性碱性磷酸酶活性测定对小儿佝偻病的诊断价值。方法：采用全血干化学和免疫浓缩技术检测血液中骨源性碱性磷酸酶活性，并与临床诊断为佝偻病的结果进行比较。结果：368例中BALP〈200U／L113例，占30．7％，（200～250）U／L120例，为32．6％，〉250U／L135例，为36．7％。3月～组与2岁～组BALP检测结果比较统计学上无差异（P〉0．05），2岁一组与4～5岁组比较统计学上有显著性差异（P〈0．05），3月～组与4～5岁组比较统计学上差异显著（P〈0．001）。根据临床表现诊断为佝偻病的92例，为36．1％，临界组与阳性组中诊断为佝偻病的结果进行比较统计学上有显著性差异（P〈0．001）。结论：BALP检测方法简单，对小儿佝偻病的早期诊断、疗效观察及预防具有现实的临床意义。     

慢性粒细胞白血病100例骨髓组织病理学Hannover分类法意义探讨

本文对100例慢性粒细胞白血病(CML)患者进行组织病理学研究,应用Hannover国际分类法进行分类,观察到骨髓组织病理学中巨核细胞增多者临床症状较重,中位生存时间较短,认为该分类法对临床及预后判断有指导意义,比既往应用的Bartl及Frisch分类法优越。     

Helping families of homicide victims: A multidimensional approach

Homicide inflicts massive injury upon the intrapsychic and interpersonal realities of the surviving kin of murder victims. A New York City pilot program of outreach and counselling to 1182 families of Brooklyn homicide victims suggests that surviving kin undergo the symptoms of traumatic stress disorder. Recovery is prolonged by knowledge that the perpetrator is usually alive and in some cases unpunished, by repetitive confrontations with the criminal justice system and by the multiple losses endured: loss of a family member, loss of illusions of safety and invulnerability, loss of a sense of trust in the surrounding community, and loss of a belief system. Effective help to survivors requires interventions that respond to all aspects of the survivors' losses.     

经皮穿刺腰椎间盘切吸术治疗腰椎间盘突出症的远期疗效

目的 观察X线电视引导下经皮穿刺腰椎间盘切吸术治疗腰椎间盘突出症的远期疗效。方法 32例经CT扫描证实的腰椎间盘突出症患者，其中，膨出型29例，游离型2例，以及突出型1例，均经X线电视引导下经皮穿刺腰椎间盘切吸术治疗，术后均经随访0.5～11.0a。结果 术后1周～3个月，32例中的24例临床症状与体征得到有效控制或明显减轻，随访5～11a观察表明，症状完全消失和明显减轻者分别见于23例和6例，总有效率90.6%，预后极好和较好者均见于膨出型腰椎间盘突出症患者。结论 游离型和突出型腰椎间盘突出症的疗效均不理想，因此，术前认真选择适应证是获得理想疗效的关键性因素。     

恶性血液病患者血清红细胞生成素的水平及其临床意义

目的 探讨恶性血液病患者血清红细胞生成素(Epo)的含量及其意义。方法 采用夹心酶联免疫法测定40例恶性血液病患者及18例健康人血清Epo，同时检测其血红蛋白及红细胞数。结果 恶性血液病中，急性白血病及多发性骨髓瘤的Epo较正常人明显增高(P＜0．001)，其血红蛋白值则明显低于正常人(P＜0．001)，慢性白血病及淋巴瘤的Epo也比正常人高(P分别为＜0．002及＜0．05)，但其血红蛋白值则与正常人无显著差异(P＞0．05)。各组病人血清Epo水平均与血红蛋白及红细胞数呈负相关。结论 恶性血液病血清Epo水平较对照组明显升高，并与血红蛋白及红细胞数呈负相关。除贫血、缺氧，导致体内Epo活性反馈，使患者Epo水平增高外，可能还和红系祖细胞利用Epo减少有关。rhEpo对Epo基础值不太高的某些恶性血液病伴发的贫血是一种有效的治疗措施。     

原发性单纯性脑干出血52例临床研究

目的研究原发性单纯性脑干出血的病因、诊断、治疗、预后及预防。方法对52例原发性单纯性脑干出血的临床资料进行回顾性分析。结果预后良好25例，优良率为48．1％；死亡21例，死亡率40．4％；出血量≤5．0ml死亡率21．9％（7／32），出血量≥5．1ml死亡率70．0％（14／20），出血量〉10.0ml 10例全部死亡。结论原发性单纯性脑干出血发病急，病情重，死亡率高，预后差；高血压为本病的主要发病原因；CT是原发性单纯性脑干出血的安全、可靠诊断方法；适时进行气管切开及亚低温治疗能有效提高疗效及降低死残率；严格控制血压是预防原发性单纯性脑干出血的重要措施。     

Aortic root dilatation may alter the dimensions of the valve leaflets

Objective: Valve-sparing surgery can be used in patients with dilated aortic roots and aortic insufficiency (AI) but has not become a common practice, in part because the spared valve may be incompetent. Our goal was to study how the dimensions of the aortic root and leaflets have changed in such patients. Methods: Fourteen patients with dilated aortic root and AI were examined by transesophageal echocardiography. The annulus diameter, sinotubular junction (STJ) diameter, sinus height, leaflet free-edge length, and leaflet height were measured. Correlations among these dimensions and with the AI grades were explored. Measurements were also made in 19 normal human aortic valves from silicone molds. Results: There was no evident change in the average diameter of the annulus between the normal valves and those in the dilated aortic roots. The STJ diameter was obviously increased in the dilated aortic roots; the aortic sinuses also appeared to be taller and the leaflets larger than normal. The leaflet free-edge length, the leaflet height, and the sinus height were found to increase with the dilated STJ diameter. The degree of AI was not found to correlate well with any of the dimensions measured. Conclusions: The dimensions of the leaflets may change parallel to aortic root dilatation with AI. Therefore, during valve sparing, it may be necessary to correct both the dilatation of the root and the leaflet free-edge length to achieve a competent valve.

Efficacy of a patient-training videotape on motor fluctuations for on-off diaries in parkinson's disease

Patient on-off diaries are used in clinical trials, but a method to assure agreement between patient and examiner has never been developed. We tested whether a patient-teaching tape increased the rate of agreement between patient diary ratings and simultaneous neurologic assessment by a trained professional. A total of 32 consecutive patients who had Parkinson's disease with motor fluctuations independently completed a 4-h on-off diary (nine ratings) at the same time as an examiner. Those with <80% agreement with the examiner (n = 20) were randomized to view either a training tape that showed motor fluctuations (experimental group) or another videotape of general patient educational material (control group). All patients then underwent the same 4-h assessment of motor fluctuations. To test for long-term retention, they returned 1 month later and, without reviewing the videotape, underwent a final 4-h correlation assessment. After the training tape, the experimental group showed significant improvement, whereas the control group showed no improvement. Furthermore, another month later, the improvement in the experimental group was retained. Based on these findings, we suggest that future clinical trials assessing motor fluctuations incorporate this tape into their basic methodology.
