Congenital quadricuspid aortic valve with tetralogy of Fallot and pulmonary atresia

We report the case of a 4-year-old girl who had quadricuspid aortic valve regurgitation with tetralogy of Fallot and pulmonary atresia. This combination is very uncommon. Aortic valve replacement was performed successfully due to aortic regurgitation which had progressed one year after the total repair. The dilated aortic annulus plus quadricuspid aortic valve may result in progressive aortic regurgitation for a short period.     

Outcomes of low-vision services using optometric and multidisciplinary approaches: a non-randomized comparison

Consecutive patients (n = 215) who were referred to optometric (55%) or multidisciplinary (45%) low-vision services and above 50 years of age were recruited from four hospitals in the Netherlands. They completed two vision-related quality of life questionnaires, the Vision Quality of Life Core Measure (VCM1) and the Low Vision Quality of Life Questionnaire (LVQOL), before their first visit with low-vision services and 1 year later. At follow-up, patients referred to multidisciplinary low-vision services had lower scores on the mobility subscale of the LVQOL than patients referred to optometric low-vision services [5.3 points; 95% confidence interval (CI): 0.2-10.5]. Paired sample t-tests for the two groups of patients taken together show improvement for the VCM1 (3.1 points; 95% CI: 0.6-5.6) and deterioration for the basic aspects of vision (3.5 points; 95% CI: 1.1-5.9) and the mobility (6.6 points; 95% CI: 3.7-9.5) subscales of the LVQOL. In conclusion, people referred to optometric services showed less deterioration in mobility than those referred to multidisciplinary services. No differences were observed for any of the other subscales of the LVQOL and the VCM1. Future research in this field should include randomized controlled designs comparing low-vision services with no treatment or placebo.     

慢性肺心病哮喘持续状态218例临床分析

目的探索治疗慢性肺心病哮喘持续状态的方法。方法回顾性分析1983年10月～2005年3月收治的218例慢性肺心病哮喘持续状态患者的临床资料。结果哮喘持续状态在48h以内被控制的62例（28．4％）；在72h以内控制的56例（25．7％）；在120h以内控制的25例（11．5％）；在168h以内控制的34例（15．6％）；痊愈出院177例（81．2％）；死亡41例（18．8％）。结论（1）治疗慢性肺心病哮喘持续状态．根据患者的病理变化．综合治疗．效果显著。（2）在治疗过程中．要恰当选择抗生素和平喘药；对那些血液黏滞度增高的患者．要加用血液稀释疗法。（3）测定血液黏滞度和氧饱和度．可以指导治疗、估计预后．应当列为常规检查。     

应用秩和比法研究门诊人数增长与门诊医疗质量因子的关系

目的研究医院门诊人数增长与门诊医疗质量因子的关系,找出影响门诊人数增长的主要门诊医疗质量因子。方法利用秩和比法对实例进行分析。结果影响门诊人数增长的门诊质量因子,首先是高中级职称比(χ2=32.43,P<0.05),其次是副高以上职称的坐诊工时比(χ2=31.91,P<0.05),再次是新技术项目或重大改革(χ2=28.54,P>0.05)。结论研究医院门诊人数增长与门诊医疗质量因子的关系时,秩和比法有应用推广的价值。     

粉防己碱对野百合碱致大鼠肺动脉构形重建的逆转作用

以野百合碱复制Ｗｉｓｔａｒ大鼠肺动脉高压模型，用特殊染色方法观察粉防已碱对野百合碱致大鼠肺动脉构形重建的逆转作用，结果表明粉防已碱可选择性的降低野百合碱诱导的大鼠肺动脉高压的作用，并明显地逆转肺血管及肺组织损伤，降低肺动脉高压和右心室肥大，对体循环压力无影响

Phase II trial of piroxantrone in patients with recurrent and metastatic squamous cell carcinoma of the head and neck

Summary Twenty-two patients with recurrent or metastatic squamous cell carcinoma of the head and neck were treated with piroxantrone 150 mg/m² intravenously every 21 days. There were no objective responses. The 95% upper confidence bound for response is 15%. Primary toxicity was hematologic.
