电影对边缘性人格障碍症的抑治及电影治疗的独特价值 总被引:1,自引:0,他引:1
艺术治疗是一种独特而神奇的心理治疗方法,对精神病患者的疗效尤为显著。电影治疗是新兴的艺术治疗途径.亦为一种医学思维。临床表明,在私闭的空间,给某些特定类型的精神疾病特别是边缘性人格障碍症患者播放特选的影片,往往能促使患者受到强烈的满灌,召唤其痛苦回忆,抚慰心灵伤楚,进而促其身心稳定,甚至治愈病情。电影治疗是医学与电影学的交叉与融合,是人文科学与自然科学的前沿,通过关呼唤人性之善,前景无限。 相似文献

目的观察银丹心泰滴丸治疗冠心病心绞痛的疗效。方法将76例患者随机分为两组,对照组采用常规抗心绞痛治疗包括硝酸酯类,钙拮抗剂,β-受体阻滞剂等治疗,治疗组在对照组的基础上加用银丹心泰滴丸口服,两组疗程均为8周,观察两组治疗前后心绞痛症状、心电图及血脂变化情况。结果治疗后,心绞痛疗效有效率治疗组84.21%,对照组63.16%;心电图疗效有效率治疗组81.58%,对照组60.53%;血脂变化治疗组有明显改善,对照组无明显改善,两组差异有统计学意义(P值〈0.05)。结论银丹心泰滴丸可明显改善心肌缺血情况,缓解心绞痛症状,降低胆固醇和甘油三酯,提高患者的生活质量。 相似文献

The aim of this trial was to investigate the efficacy and toxicity of combination chemotherapy with etoposide and ifosfamide (ETI) in the management of heavily pretreated recurrent or persistent epithelial ovarian cancer (EOC). Patients with recurrent or persistent EOC who had measurable disease and at least two prior chemotherapy participating in this phase II trial were to receive etoposide at a dose of 100 mg/m2/day intravenously (IV) on days 1 to 3 in combination with ifosfamide 1 g/m2/day IV on days 1 to 5, every 21 days. Thirty-seven patients were treated; about 78% had previously received more than two separate regimens. The response rate (RR) was 18.9% and median duration of response was 7 months (range, 1-15). Treatment free interval prior to ETI (TFI) has significant correlation with RR rate (P=0.034). Patients (n=6) with TFI ≥6 months had 50% of RR, while patients (n=31) with TFI <6 months had 12.9%. Median survival was 9 months at a median follow-up of 9.2 months. Grade 3 or 4 toxicities included neutropenia in 20.1% of the 139 cycles of ETI, anemia in 7.2% and thrombocytopenia in 8.6%. The ETI produces relatively low toxicity and modest activity in heavily pretreated recurrent or persistent EOC. This is significant in patients with TFI ≥6 months. 相似文献

Clinical and personal equipoise exists when a clinician has no good basis for a choice between two or more care options or when one is truly uncertain about the overall benefit or harm offered by the treatment to his/her patient. For most manual therapy trials, equipoise does not likely exist. Because of the nature of the intervention a lack of equipoise can lead to bias and may account for a portion of the ‘effect’ that has traditionally been assigned to the intervention. Although there are methodological mechanisms to reduce the risk of bias associated with a lack of equipoise, most of the manual therapy trials to date are likely guilty of this form of bias. 相似文献

This study aims to explore the genetic and environmental contributions to autistic-like behaviors in a general population
sample of toddlers. In a classic twin study of 313 same-sex, 2-year-old twin pairs, autistic-like behaviors were assessed
via parent ratings on the pervasive developmental problems subscale of the Child Behavior Checklist and observationally using
tester ratings on the orientation/engagement subscale of the Behavior Rating Scale. Analyses show moderate, significant heritabilities
for both measures of autistic-like behaviors, as well as modest, but significant shared environmental effects. These genetic
and environmental influences overlap greatly between the two measures. Autistic-like behaviors in 2-year-old twins are largely
genetic in etiology, but are also influenced by a shared environmental component at this age. This is the first study to examine
the etiology of such behaviors in a sample of toddlers, thus providing novel information which could guide future research
on genetic and environmental factors that affect these behaviors.
