侗族预防医学思想初探

在实地调查搜集民族民间传统医药资料的基础上,把广泛流传于侗族民间预防疾病的方法,以及民族风情、民俗习惯中对防治疾病非常有利的内容进行综合分析归纳;对侗族预防医学思想的形成进行了初步探索,为深入系统整理侗族预防医学思想体系提供了具有一定价值的参考资料。     

列车乘务员SCL—90评定结果分析

采用ＳＣＬ—９０症状自评量表对某铁路分局４６７名列车乘务员的心理卫生状况进行了分析。结果显示总均分、阳性症状均分、阳性项目数、九组症候群因子分、达到或超过中等严重程度的发生频数均显著高于对照组。经多元逐步回归分析,仅细菌总数和二氧化碳对列车乘务员心理卫生状况有一定影响,其原因多与工作环境的不良因素和工作性质有关。     

恶性肿瘤放疗前后血清可溶性白细胞介素2受体含量变化的临床意义

目的　探讨血清可溶性白细胞介素２ 受体（ｓ Ｉ Ｌ２ Ｒ）水平与恶性肿瘤患者的病期及疗效的关系。方法　采用双抗体夹心 Ｅ Ｌ Ｉ Ｓ Ａ 法检测１５９ 例恶性肿瘤患者放疗前后血清ｓ Ｉ Ｌ２ Ｒ 水平。结果　恶性肿瘤患者放疗前血清ｓ Ｉ Ｌ２ Ｒ 水平明显高于正常对照组（ Ｐ＜ ００５）;放疗后血清ｓ Ｉ Ｌ２ Ｒ 水平明显低于放疗前（ Ｐ ＜ ０００１）;晚期患者（Ⅲ＋ Ⅳ期）不论是放疗前或放疗后 ｓ Ｉ Ｌ２ Ｒ 水平均明显高于早期患者（Ⅰ＋ Ⅱ期）（ Ｐ ＜ ００５）;各类恶性肿瘤之间血清ｓ Ｉ Ｌ２ Ｒ 水平无显著性差异（ Ｐ ＞００５）。结论　ｓ Ｉ Ｌ２ Ｒ水平在各种恶性肿瘤中的表达无特异性;检测恶性肿瘤患者ｓ Ｉ Ｌ２ Ｒ 放疗前后水平,是对病情估计和治疗疗效评价的一项参考指标。     

电化学治疗前列腺增生的体外实验研究

目的：探讨电化学在前列腺增生症治疗中的应用。方法：对８例人良性前列腺增生组织标本进行了体外实验,观察不同电极与电量设置对前列腺增生组织病理变化范围的影响。结果：不同电极设置,电极周围组织变性坏死区域半径不同。随电量增加,电极周围组织病理变化范围亦递增。导尿管同置正负极,电量为３００库仑时,正负电极周围损伤范围达半径１０ｍｍ。研究表明,导尿管同置正负极,电极周围损伤范围大,治疗后前列腺腔塑型成管状,且操作简单。结论：选用合适的电极和恰当的电量,可使前列腺组织产生有效的病理变化范围,从而取得前列腺增生症的治疗效果。     

中药颤振平治疗老年颤证临床和实验研究

观察中药颤振平胶囊治疗老年颤证 30例 ,总体临床疗效进步率 2 3.33% ,总有效率 80 .0 0 %。单纯中药组疗效与中药合西药组疗效近似。实验研究提示颤振平胶囊能增加脑干组织中单胺递质(NA、DA)的含量 ,增加利血平化小鼠的体重 ,增加正常小鼠的自主活动。小鼠口服最大耐受量未见毒性反应或死亡。     

Treatment of infected left ventricular assist device using antibiotic-impregnated beads

There is no well-established therapy for treating infections of heart-assist or artificial heart devices, a serious problem with life-threatening consequences. We used a promising new approach in which antibiotic-impregnated polymethylmethacrylate beads were placed around an implanted left ventricular assist device to control an external blood pump infection in a bridge-to-transplant patient. In this case report, we describe the potential of antimicrobial-impregnated polymethylmethacrylate beads for in situ control of infections involving external surfaces of cardiovascular devices.     

National health expenditures, 1998

In 1998, national health care expenditures reached $1.1 trillion, an increase of 5.6 percent from the previous year. This marked the fifth consecutive year of spending growth under 6 percent. Underlying the stability of the overall growth, major changes began taking place within the Nation's health care system. Public payers felt the initial effects of the Balanced Budget Act of 1997 (BBA), and private payers experienced increased health care costs and increased premium growth.     

Pooled purchasing: who are the players?

Data from the 1997 Robert Wood Johnson Foundation Employer Health Insurance Survey provide the first national estimates of the prevalence of pooled purchasing under all major arrangements. About one-quarter of all businesses participate in a pool; smaller businesses are more likely to participate, and there is substantial geographic variation in the prevalence of pool participation. Pooling appears to have modest positive effects on the availability of employee choice among plans (especially health maintenance organizations) and on the availability of information about plan quality. On the other hand, pooling as now construed does not seem to have enhanced the accessibility or affordability of insurance to employers.     

Comparing employee health benefits in the public and private sectors, 1997

Data from the 1997 Robert Wood Johnson Foundation Employer Health Insurance Survey provide new information comparing public- and private-sector employee health benefits. The federal government is ahead of other employers in adopting managed competition principles using financial incentives and consumer information to promote choosing efficient plans. Federal employees experience a $200 annual compensation gap relative to those in the private sector, but it is partly explained by advantage in purchasing power. In contrast, state and local governments make higher payments toward health insurance than private-sector employers do. Their premiums are equivalent, but they pay a greater share of the total cost.
