明代中晚期的礼仪之变及其社会内涵——以江南地区为考察中心

中国传统的礼仪制度是在以身份等级制为内核的社会架构中形成的，同时又对传统的社会形态起着维系的作用。然而，至明代中晚期，婚、丧、冠、寿、社交等礼仪惯制却发生了诸多变异，并在江南地区尤为典型地表现出来。考察并分析当时的礼仪之变，可以发现。婚礼的变古出新，丧礼的淆乱旧制，冠礼的废弛，寿诞礼的盛行，人际交往的尊卑失序。所反映的正是社会的震荡与变迁。     

A cross-sectional survey of patients' beliefs about stress and their help-seeking behaviour

BACKGROUND: Stress has become an increasingly common presentation in general practice. This may relate to an increase in stress in people's lives or a change in the meaning of stress and its conceptualisation as a legitimate problem for the GP. AIM: To explore patients' beliefs about stress, their association with help-seeking behaviour, and to examine differences by ethnic group. DESIGN OF STUDY: Cross-sectional survey of general practice patients attending to see their GP. SETTING: An inner-city London practice. METHOD: Consecutive general practice patients completed a questionnaire, which involved rating a series of symptoms for the extent to which they were associated with stress and describing their help-seeking behaviour. In total, 548 patients completed the questionnaire. Most patients described themselves as black Caribbean (n = 163), black African (n = 48), or white British (n = 187). RESULTS: The symptoms most frequently associated with stress were sleeping problems, feeling depressed, feeling panicky, having high blood pressure and feeling anxious; feeling ashamed, experiencing indigestion, having diarrhoea, feeling hot or cold, and suffering from constipation were least commonly associated to stress. This model of stress did not vary by ethnic group. Ethnic group differences were found for the association between the model of stress and help-seeking behaviour. Although white British patients consistently reported that the more a symptom was seen as indicative of stress, the more likely they would be to visit the doctor for that symptom, this association was not found for either black Caribbean or black African patients. CONCLUSIONS: The belief that stress-related symptoms are a legitimate problem for the GP is not universal and varies according to ethnic group. Stress is used by different patients in different ways and offers a variable pathway to the doctor.     

Is herpes zoster a marker for occult or subsequent malignancy?

BACKGROUND: It has been suggested that herpes zoster may be a marker for occult malignancy. AIM: To examine the emergence of a subsequent cancer diagnosis in patients with and without herpes zoster. DESIGN OF STUDY: Retrospective cohort study. SETTING: Results were based on the database of Intego, an ongoing Belgian general practice-based morbidity registry, covering 37 general practitioners and including about 311 000 patient years between the years 1994 and 2000. METHOD: Survival analysis comparing the emergence of malignancy in patients with and without herpes zoster. RESULTS: The number of patients below the age of 65 years with herpes zoster, cancer or both was too low to draw any sensible conclusions. Above the age of 65 years we identified a significant increase of cancer emergence in the whole group and in females (hazard ratio = 2.65, 95% confidence interval = 1.43 to 4.90), but not in males. No difference could be identified in the first year after the herpes zoster infection. CONCLUSION: Our results do not justify extensive testing for cancer in herpes zoster patients. The association we identified, however, leaves open a number of questions with respect to the physiopathology behind it.     

复方醋酸环丙孕酮和罗格列酮序贯用药对氯米芬抵抗的多囊卵巢综合征患者内分泌及生育功能的影响

目的探讨复方醋酸环丙孕酮和罗格列酮序贯用药对改善多囊卵巢综合征（PCOS）患者生育功能的临床疗效。方法30例氯米芬抵抗的PCOS胰岛素抵抗患者，口服复方醋酸环丙孕酮3个月后，罗格列酮联合氯米芬用药6个月，比较用药前后体重指数、月经周期、生殖激素水平、排卵率、妊娠率、血糖和胰岛素水平的变化。结果与用药前相比，服用复方醋酸环丙孕酮后，雄激素水平和LH／FSH值明显降低（P〈0．05），服用罗格列酮后，胰岛素抵抗指数（Homa IR）、胰岛素分泌指数（Homa β）以及β细胞功能评定指数（MBCI）均较用药前降低（P〈0．05）。结论复方醋酸环丙孕酮和罗格列酮序贯用药可有效地抑制氯米芬抵抗的PCOS患者的高雄激素血症，改善胰岛素抵抗及生育功能。
