某职业学院大学新生的心理问题与分析

目的 了解某职业学院大学一年级新生的心理问题并进行有效的调适。方法 采用精神卫生调查表(CES—D)对广东科学技术职业学院2002级2000名专科第一学期新生进行调查，共发放问卷2000份，收回1988份，问卷收回率99．4％，有效问卷1984份，有效率99．7％。结果 在1984名大学新生中有599人存在程度不同的心理问题，占被告调查人数的30．19％。结论 大学新生的心理问题普遍，大学教育工作者应该对大学新生进行有针对性的心理干预和调适，提高大学新生的心理素质，以利于他们的健康成长。     

正常成人睾丸血流的彩色多普勒观察

为了探讨彩色多普勒血流显像技术显示正常人睾丸内血流的可行性，并探讨睾丸的血流动力学特征，我们对２０名正常人双侧睾丸进行了彩色多普勒检查。结果显示，彩色多普勒能显示所有睾丸的包膜动脉、向心动脉。正常睾丸的包膜动脉和向心动脉收缩期峰值血流速度的均值分别为９．００ｃｍ／ｓ和７．４２ｃｍ／ｓ；舒张末期血流速度均值分别为３．５０ｃｍ／ｓ和３．３８ｃｍ／３，本文对睾丸彩色血流显像和多普勒频谱特点也作了讨论。     

Suppressive effect of immature erythroid cells on the B-cell proliferation

Immature erythroid cells suppress the proliferative response of preactivated B lymphocytes to lipopolysaccharide. The same effect is observed when recombinant human interleukin-2 or culture medium conditioned by preactivated T or B cells is added to cultured cells. Suppressive nucleate erythroid cells are resistant to leucine methyl ester. Translated fromByulleten’ Eksperimental’noi Biologii i Meditsiny, Vol. 123, No. 1, pp. 66–70, January, 1997     

The significance of a rapid cold hemagglutination test for detecting mycoplasma infections in children with asthma exacerbation.

BACKGROUND AND PURPOSE: Mycoplasma pneumoniae infection is a frequent cause of community-acquired respiratory infections in children and adults. However, standardized, rapid, specific methods for its diagnosis are lacking. The relationship between M. pneumoniae infection and asthma exacerbation has been recently discussed in the literature. We investigated the accuracy of rapid detection of mycoplasma infection by cold hemagglutination test compared to conventional enzyme immunoassays. The clinical characteristics of mycoplasma infection seen during emergent visits in asthmatic children were reviewed. METHODS: We retrospectively reviewed medical records of patients with asthma exacerbation visiting the Department of Pediatric Emergency, National Taiwan University Hospital, over a 12-month period. Subjects 2-18 years of age diagnosed with asthma at our outpatient clinic were included in this study. Patients with immunodeficiency, congenital anomalies, neurological diseases and irregular follow-up were excluded. RESULTS: A total of 269 children (174 males and 95 females) with a mean (+/- standard deviation) age of 6.15 +/- 3.08 years were included. The prevalence of asthma exacerbation in regular follow-up patients was 13.4%, and as many as 19.6% of cases (74/378 person-times) required hospitalization. Asthma attacks were most prevalent during December. 126 patients had both rapid cold hemagglutination testing and mycoplasma immunoglobulin M titers determined using acute blood samples drawn in the emergency room; 46 (36.5%) of these patients demonstrated mycoplasma infection. Sensitivity and specificity of the rapid cold hemagglutination test was 78.3% and 41.3%, respectively. The positive predictive value was 43.4%. Comparison of patients with or without mycoplasma infection revealed no differences in gender, age, chest X-ray findings, and most symptoms/signs and laboratory data, except that more signs of fever and auscultatory rales were seen in the non-mycoplasma infection group. CONCLUSIONS: Mycoplasma infections could be an exacerbating factor for asthma, and the rapid cold hemagglutination test should not be a guideline for prescribing macrolides in the emergency room.

Role of glycolysis in the genesis of early postocclusion arrhythmias

Antiarrhythmic effects of phosphorylated glycolysis intermediates glucose-1-phosphate, fructose-1,6-diphosphate, and phosphoenolpyruvate in early postocclusion arrhythmias are shown in rat experiments; in contrast to these, D-glucose, sodium pyruvate, and monoiodacetate, a glycolysis inhibitor, exert no appreciable antiarrhythmic effect.
