Association between recurrent aphthous ulcers and tobacco habits

Abstract – The study is a compilation of data on oral mucosal lesions collected among 20 333 people aged 15 yr and over. The aim was to calculate the correlation between the prevalence of recurrent aphthous ulcers and various tobacco habits. The prevalence of aphthous ulcers in the population was 17.7% including cases referring to episodes within the last 2 yr. There was a negative correlation between the prevalence of ulcers and tobacco habits. The suppression of ulcers was most evident for those groups smoking pipe or cigarettes without filter and only moderate for those using snuff. Further, heavy smokers had a lower frequency of ulcers than moderate smokers.     

差示分光光度法测定牛黄类中成药中胆红素的含量

本文利用胆红素溶液在光照下易氧化变色及其吸收光谱发生显著变化的性质,在波长453 nm处,测其光照前后的吸收度差值(△A),△A与胆红素溶液浓度呈线性关系,对含牛黄的中成药(六应丸,六神丸和牛黄消炎丸)中胆红素进行了定量,并对其它组分进行了光照试验,排除了光照对其它组分的影响,从而确定了此法的可行性。     

An experiment in police-community relations: A small group approach

To study the effectiveness of group discussion in mitigating the rising hostility between police and residents of the urban ghetto, two 15-member groups of police and ghetto residents held weekly discussions, led and observed by university researchers, for 12 weeks. Attitude scales administered at the beginning and end of the study, as well as recorded logs of the meetings, reveal increased understanding and empathy between initially hostile and defensive participants by the end of the study. With increased awareness of each others' problems came an increased faith in the power of cooperation to solve problems. Police became more interested in attempting to affect the causes of problems than in serving merely as disciplinarians, and some of the community members began to attempt to instill in their neighbors a more friendly attitude toward the police.He directed the Police-Community Relations Pilot Project, which was funded by the Office of Juvenile Delinquency and Youth Development, U.S. Department of Health, Education, and Welfare, through the institute's Training Center in Youth Development. Mrs. Steinbruner, editor and evaluator for the training center, was a member of the pilot project staff. The participation of Dr. Kenneth Benne, Dr. John Cartwright, and W. Robert McClain, of the Boston University Human Relations Center, is gratefully acknowledged.     

急性淋巴细胞白血病(上)

急性淋巴细胞白血病是淋巴前体细胞异常引起的恶性疾病,儿童与成人均可能发生。儿童发病高峰2～5岁。有效治疗的稳步进展使本病在儿童中的治愈率80％以上,同时为新的治疗方案提供了良机,新方案将保留我们在白血病无病生存病例中获得的治疗经验,同时减轻当前强化治疗方案中的毒副作用。     

急性淋巴细胞白血病(下)

5 风险评估对病人的复发风险进行评估以确保只有高危病例才被施予极强治疗.研究表明采用成人方案治疗的青少年病人,其效果要显著差于使用儿童方案治疗的同年龄组.     

冠心病患者实施健康信念模式干预效果评价研究

目的探讨冠心病（CHD）患者实施健康信念模式干预的效果。方法将140例CHD患者随机分对照组和干预组,各70例,对照组给予常规治疗和护理,干预组在对照组的基础上给予健康信念模式干预措施;比较两组的遵医行为、干预效果及生活质量评分。结果实施干预后,干预组的遵医行为备维度得分均明显好于对照组（P〈0．0.01）;干预组的各干预效果指标均明显好于对照组（P〈0．05）：干预组的生活质量各维度指标也明显好于对照组（P〈0．01）。结论CHD患者实施健康信念模式干预后,明显提高CHD患者的遵医行为和生活质量评分,干预效果明显。
