人巨细胞病毒感染对肾移植受者血清白细胞介素－6水平的影响

应用ＰＣＲ检测ＨＣＭＶ－ＤＮＡ，ＥＬＩＳＡ检测ＨＣＭＶ－ＩｇＭ、ＩｇＧ，诊断肾移植受者ＨＣＭＶ感染，６５例受者中ＨＣＭＶ感染者３９例，非感染者２６例。应用ＭＴＴ法检测受者血清ＩＬ－６生物活性，阐明了ＨＣＭＶ感染对肾移植受者血清ＩＬ－６水平的影响。结果表明：感染与非感染组间血清ＩＬ－６水平差异无显著性（Ｐ＞０．０５）；６例原发性感染者血清ＩＬ－６水平随感染时间延长呈增高及降低双相改变，表明慢性迁延性感染者血清ＩＬ－６水平降低。临床工作中监测ＨＣＭＶ感染的肾移植受者血清ＩＬ－６水平变化具有重要意义。

The effects of hyperthyroidism on oesophageal motility.

This study, evaluating the effects of hyperthyroidism (HT) in oesophageal motility, depended on an oesophageal radionuclide transit test. A modified standard method was used to calculate: (a) total mean transit time (MTT), (b) residual fraction (RF) and (c) retrograde index (RI) in a supine position. Eighteen untreated patients with HT and 25 normal volunteers (NV) with a similar age distribution were included in this study. The results showed that oesophageal motility in patients with HT was worse than in the normal controls (P < 0.05 by Student's t-test). The correlation of MTT, RF and RI with size and function of thyroid glands in the patients with HT were calculated to explain the effects of HT in oesophageal motility. The results showed that neither the size nor the function of the thyroid glands in HT affected oesophageal motility.     

Mediating effects of social support on firefighters' sense of community and perceptions of care

This study examined the relationship between psychological sense of community, social‐support networks, and care‐giver stress and satisfaction among firefighters. No significant gender differences were obtained, but zero‐order correlates demonstrated significant relationships among all four variables. In examining the mediating effects of social‐support satisfaction, partial mediation for psychological sense of community on care‐giver satisfaction was determined, as well as full mediation for psychological sense of community on care‐giver stress. Therefore, firefighters who are satisfied with the support they receive may experience less stress with their care giving than those who experience low levels of support satisfaction. Future studies should assess these relationships more extensively in other areas of civic responsibility among public‐service employees to delineate effective support avenues. © 2004 Wiley Periodicals, Inc.

The utilization of traditional Chinese medicine and associated factors in Taiwan in 2002

Background Previous studies have noted that there is a high utilization rate of traditional Chinese medicine (TCM) services in Taiwan, China and in western countries, but few studies investigated factors associated with the utilization of TCM in Taiwan. This study analyzes the utilization rate and the factors associated with the utilization of TGM in Taiwan. Methods Data for this study were from the 2002 HPKAP Survey that conducted the face-to-face questionnaire interviews of people aged 15 years and over from October 2002 to March 2003 in Taiwan. This study analyzed the utilization of TCM outpatient services, including admission to the hospital and clinic visits. Results A total of 26 755 participants completed the survey in the six-month period. The data revealed that 10.4% of participants had utilized TCM services in the past one month while 4.2% of participants utilized TCM only (without using Western medicine outpatient services (WM) or Folk therapy (F'I')). The average visits of TCM services per patient was higher among people who had utilized TCM and FT services (2.68 visits) than among those who had utilized WM and FT services (2.15 visits) or TCM services alone (2.15 visits) during the previous one month. Younger people (odds ratio OR= 1.78, 95%C/= 1.47-2.16), women (compared with men), and people with higher education levels (OR = 1.58, 95%CI =1.25-1.98) were more likely to visit TCM than compared groups. People with self-reported poor health status (OR = 2.07,95%CI = 1.76-2.44) and people who exercise regularly (OR = 1.17, 95%CI = 1.07-1.27) had higher ORs to visit TCM service than comparison group.Conclusions There is a high utilization of TCM in Taiwan. Further studies are needed to investigate the related factors and determinants between the utilization of TCM and the utilization of FT in Taiwan.     

伽玛刀治疗高危前列腺增生症的临床应用

目的探讨伽玛刀在不适合开放手术或经尿道电切术的高危前列腺增生患者治疗中的应用。方法采用深圳奥沃公司生产的OUR-QGD型立体定向全身伽玛刀治疗20例高危前列腺增生患者。应用国际前列腺症状评分(IPSS)、前列腺重量、最大尿流率(Qmax)、残余尿量作为评价指标。观察上述数据在治疗前后的改变及其临床意义。结果术后随访6个月,IPSS评分由治疗前29分降至19.6分(P<0.01)。前列腺重量平均值均由治疗前的(56.4±4.4)g减少至(54.8±4.3)g(P>0.05)。最大尿流率平均值由治疗前的(6.7±1.8)ml/s增加至(11.5±1.7)ml/s(P<0.01),残余尿量平均值由治疗前的(85.1±27.8)ml降至(50.9±15.6)ml(P<0.01)。结论立体定位体部伽玛刀治疗高危前列腺增生症患者具有简便、安全、无创、痛苦小、并发症少、疗效好,可不需住院等优点,对不愿意接受手术或不宜手术的高危前列腺增生患者不失为一种良好的治疗方法,但费用较高。
