A Correlational Test of the Relationship Between Posttraumatic Growth,Religion, and Cognitive Processing

The present study examined the degree to which event related rumination, a quest orientation to religion, and religious involvement is related to posttraumatic growth. Fifty-four young adults, selected based on prescreening for experience of a traumatic event, completed a measure of event related ruminations, the Quest Scale, an index of religious participation, and the Posttraumatic Growth Inventory. The three subscales of the Quest Scale, the two groups of rumination items (soon after event/within past two weeks), and the index of religious participation were entered in a standard multiple regression with the total score of the Posttraumatic Growth Inventory as the dependent variable. The degree of rumination soon after the event and the degree of openness to religious change were significantly related to Posttraumatic Growth. Congruent with theoretical predictions, more rumination soon after the event, and greater openness to religious change were related to more posttraumatic growth. Present findings offer some confirmation of theoretical predictions, and also offer clear direction for further research on the relationships of religion, rumination, and posttraumatic growth.

Predictive value of minor anomalies. I. Association with major malformations

We examined 4305 white newborn infants for 114 minor physical features and major malformations to evaluate the hypothesis that the presence of three or more minor anomalies is highly predictive of a major malformation. We confirmed that the infant with three or more minor anomalies is at increased risk for a major malformation. However, this risk (19.6%) was much lower than the risk of 90% popularized by Smith and based on the study of Marden et al. (J Pediatr 1964;64:357). Analysis of the findings in the two studies showed that the lower predictive value was probably related to differences in study design. Nevertheless, some minor anomalies remain essential to the early recognition of several serious malformation syndromes.     

硫酸镁对普鲁帕酮致心律失常的干预作用

目的探讨静脉滴注硫酸镁对普鲁帕酮致心律失常作用的干预效果。方法将92例心律失常患者随机分为对照组和干预组,每组46例。两组均口服普鲁帕酮,干预组同时静脉滴注硫酸镁,于治疗1周后常规心电图观察心律失常变化及致心律失常作用。结果心律失常消失率对照组为43.4%(20/46)、干预组为82.6%(39/46),致心律失常率对照组为19.6%、干预组为4.4%,两组比较有统计学意义(P<0.01)。结论普鲁帕酮抗心律失常同时有致心律失常作用,使用硫酸镁干预可降低致心律失常发生率。     

细菌快速检测试纸片法与传统方法培养结果的比较

目的比较细菌快速检测试纸片法与传统的方法在细菌检测结果上的差异。方法用试纸片法对物体表面污染菌总数和大肠杆菌进行检测,同时与传统方法作平行比较。结果检测细菌总数,用常规方法培养48 h后,细菌生长正常;而纸片法培养48 h,营养琼脂平板上无菌生长,继续培养至72 h才出现菌落。大肠菌群检测中,传统9管发酵法培养24h即有菌生长,国产大肠菌群快速检测试纸法培养36 h和日本产试纸片培养48 h才出现肉眼可见菌落。结论细菌快速检测试纸片虽能简化操作,但存在技术缺陷,且成本高。

Effect of prolonged exercise on the passage of a solid meal through the stomach and small intestine.

The effect of intermittent moderate exercise on the passage of a solid meal, labelled with radioactive Technetium sulphur colloid, through the stomach and small intestine was investigated by paired studies on seven healthy volunteers. Measurements of gastric radioactivity and breath hydrogen exertion were recorded every 10 minutes while subjects exercised in a controlled manner while seated on a bicycle ergometer. These were compared with values obtained during a separate experiment while the same subjects sat upright in a chair. Exercise significantly accelerated gastric emptying (control t 1/2 = 1.5 +/- 0.1 h; exercise t 1/2 = 1.2 +/- 0.1 h; p less than 0.02) but had no significant effect on small bowel transit time.     

Sustained, retransplantable, multilineage engraftment of highly purified adult human bone marrow stem cells in vivo

Data from many laboratory and clinical investigations indicate that CD34+ cells comprise approximately 1% of human bone marrow (BM) mononuclear cells, including the progenitor cells of all the lymphohematopoietic lineages and lymphohematopoietic stem cells (stem cells). Because stem cells are an important but rare cell type in the CD34+ cell population, investigators have subdivided the CD34+ cell population to further enrich stem cells. The CD34+/CD38- cell subset comprises less than 10% of human CD34+ adult BM cells (equivalent to < 0.1% of marrow mononuclear cells), lacks lineage (lin) antigens, contains cells with in vitro replating capacity, and is predicted to be highly enriched for stem cells. The present investigation tested whether the CD34+/CD38- subset of adult human marrow generates human hematopoiesis after transfer to preimmune fetal sheep. CD34+/ CD38- cells purified from marrow using immunomagnetic microspheres or fluorescence-activated cell sorting generated easily detectable, long- term, multilineage human hematopoiesis in the human-fetal sheep in vivo model. In contrast, transfer of CD34+/CD38+ cells to preimmune fetal sheep generated only short-term human hematopoiesis, possibly suggesting that the CD34+/CD38+ cell population contains relatively early multipotent hematopoletic progenitor cells, but not stem cells. This work extends the prior in vitro evidence that the earliest cells in fetal and adult human marrow lack CD38 expression. In summary, the CD34+/ CD38- cell population has a high capacity for long-term multilineage hematopoietic engraftment, suggesting the presence of stem cells in this minor adult human marrow cell subset.
