Crisis-related observations in competition: a case study in basketball

This study presents a unique observational approach to basketball, based on the theory of psychological performance crisis in competition. The approach used takes into account the responses of a player's actions to significant social factors such as team-mates, spectators, the coach and the referees. The contribution of this approach beyond traditional observational techniques is discussed. In our investigation, a single case design was used, in which a professional basketball player was observed during 10 home and 3 away games of the regular season. The relations between the observations and the crisis concept are discussed in detail. In addition, some relevant methodological and applied aspects are presented.     

二维彩色多普勒超声心动图诊断扩张型心肌病（附100例分析）

应用ＡＴＬ－ｕｌｔｒａｍａｒｋ超６型彩色多普勒超声诊断仪诊断扩张型心肌病１００例，并与性别、年龄相应的正常人对比分析。结果：除扩张型心肌病各组室间隔及左室后壁舒张期厚度与相应正常对照组相比无显著性差异（Ｐ＞０．０５）外，其左室舒张内径及收缩内径、左房内径明显大于正常对照组（Ｐ＜０．０１），左室射血分数及左室内径缩短分数较正常对照组明显降低（Ｐ＜０．０１），并见心腔内血流速度缓慢，颜色变淡。另在７７例病人中探及４０例瓣膜返流。提示该诊断方法对扩张型心肌病具有直观、简便、准确、迅速的优点，为本病的诊断及鉴别诊断提供了良好的手段。     

CT对眼球异物的诊断及定位

本文比较了11例眼球异物CT与X线影像，并经手术摘出异物证实，CT眼球异物检出及定位准确性均优于X线，尤其对球壁异物的定位，而且能显示断层眼球壁轮廓，具有直观效果，CT异物影像比异物明显扩大，应警惕CT伪影可能使球壁异物定位发生误差，CT目前尚不能完全取代眼球异物常规X线检查。     

抗癌药物对心脏毒性反应(附五例报告)

本文报道五例肿瘤患者在用抗癌药的治疗过程中,出现对心脏不同程度的毒性反应,并就有关几种抗癌药物的毒性作用机理及防治进行了讨论。     

军团菌肺炎的临床特点探讨

作者对１０例军团菌肺炎和１０例非军团菌肺炎患者临床资料进行分析。本组军团菌肺炎特点为：病情重、进展快、消化道症状及肌肉关节痛、低钠血症、低氧血症、代酸或呼碱发生率较高，Ｘ线胸片多见双侧或多叶肺浸润伴胸膜反应，病死率高。

Epidemiology and clinical manifestation of HIV infection in Northern Zaire

1275 patients were evaluated for HIV-1+2 seroprevalence and its association with clinical symptoms of HIV infection. Of 667 apparently healthy subjects, 8.2% had anti-HIV-1 antibodies. In 465 patients with clinical signs of AIDS, 39.4% were seropositive. 143 patients with miscellaneous symptoms had positive predictive values for HIV infection between 67% (vaginal ulcerations) and 20% (profound pyogenic abscesses). The WHO definition for AIDS had a specificity of 78.3%, a sensitivity of 72.2% and a predictive value of 61.6%.     

经食道心房调搏测定窦房结功能

对27例病窦综合征患者和42例正常对照组,经食道心房调搏,测定窦房结功能。发现病窦患者,窦房结恢复时间>1450ms;校正窦房结恢复时间≥550ms;窦房结传异时间>191ms;固有心率均明显低于正常对照组(R<0.01)。用阿托品,心得安进行功能性植物阻滞前、后观察,发现阻滞后各次参数在正常对照组中有明显降低,而病窦组则无明显差异。实验证明,经食道心房调搏方法是无创性窦房结功能检查的有效方法。     

18例胸骨后甲状腺肿瘤的外科治疗

目的 探讨胸骨后甲状腺肿瘤切除手术入路及方法。方法 对18例胸骨后甲状腺肿瘤患采用手术治疗．其中15例采用颈部低领切口入路切除肿瘤．3例颈部低领入路 正中劈胸切除肿瘤。并观察术后有无并发症发生。结果 全部患手术均获成功。术后伤口出血2例(占11％)。结论 颈部低领切口入路切除胸骨后甲状腺肿瘤是可行的，该手术操作简单，安全可靠，又具有损伤小、并发症少等优点，值得临床进一步探讨。
