腹腔镜在结直肠肿瘤手术中应用的回顾与思考

以腹腔镜为代表的微创外科技术迅速发展并取得了良好的临床效果。腹腔镜手术治疗结直肠癌存在较大争议,全盘否定或盲目应用都会影响腹部外科的发展。腹腔镜结直肠癌切除术都有其适应证并且对医生提出了更高的技术要求。随着腹腔镜技术的不断发展和完善,腹腔镜在结直肠癌手术的应用有广阔的发展空间。     

非小细胞肺癌放疗时机和放疗方式的临床决策

放射治疗是非小细胞肺癌的主要治疗手段之一。大约有3／4的肺癌患者在疾病的不同时期需要做放射治疗。针对不同的患者可以选择根治性放疗、姑息性放疗、术前、术后、放化疗联合治疗等不同的治疗方式。从治疗技术上还可以选择适形、调强、立体定向放疗等。临床医生需要辨证地应用循证医学证据,针对不同的患者刺定合理的个体化治疗方案,以提高疗效。     

2009年全球甲型H1N1流感流行病学特征分析

截至8月30日,全球5大洲177个国家或地区共报告甲型H1N1流感确诊病例254206例,死亡2837人,病死率1．12％。病例以青壮年为主,无性别差别,年龄中位数12岁～17岁（范围0岁～85岁）,约10％需住院治疗,37％的住院病例和80％的死亡病例有基础性疾病史或妊娠。全球甲型H1N1流感总体较温和,适时将其纳入季节性流感常规监测,掌握其流行病学和病原学变化,研制安全有效的疫苗;提高医务人员重症病例救治能力均能有效地预防控制甲型H1N1流感。     

抑郁症的概念及分类研究历史

宫颈癌的发病率居女性恶性肿瘤的第二位,只要做到早发现、早诊断、早治疗,宫颈癌是一种可以预防和治愈的疾病。认真地做好宫颈癌的普查和随诊,能够降低宫颈癌的发病率和病死率。因为宫颈液基细胞学设备简单,方法便利,阳性检出率高,目前已成为基层医疗单位开展宫颈癌普查的重要手段。提倡宫颈癌的普查是对全社会育龄妇女健康的关怀,是医学人文精神的具体体现。全社会的妇女都应享有这种人文关怀。     

谈谈我国肿瘤治疗中的人文关怀

目前,人类对肿瘤的治疗其实仍然在黑暗中摸索,国内医疗系统存在着过度治疗和无效治疗、对终末期患者的漠视、放弃和治疗不足等弊端,对肿瘤患者缺乏足够的人文关怀.针对这种现状,笔者从人文角度提出了一些看法和建议,以期更加尊重生命价值,体现医学的本质.     

Clinical intuition versus statistics: different modes of tacit knowledge in clinical epidemiology and evidence-based medicine

Despite its phenomenal success since its inception in the early nineteen-nineties, the evidence-based medicine movement has not succeeded in shaking off an epistemological critique derived from the experiential or tacit dimensions of clinical reasoning about particular individuals. This critique claims that the evidence-based medicine model does not take account of tacit knowing as developed by the philosopher Michael Polanyi. However, the epistemology of evidence-based medicine is premised on the elimination of the tacit dimension from clinical judgment. This is demonstrated through analyzing the dichotomy between clinical and statistical intuition in evidence-based medicine’s epistemology of clinical reasoning. I argue that clinical epidemiology presents a more nuanced epistemological model for the application of statistical epidemiology to the clinical context. Polanyi’s theory of tacit knowing is compatible with the model of clinical reasoning associated with clinical epidemiology, but not evidence-based medicine.

Differential disgust responding in people with cancer and implications for psychological wellbeing

Objectives: Evidence suggests that disgust responses, known to negatively affect psychological wellbeing, may differ in people with cancer. We performed the first quantitative investigation of three discrete types of disgust trait – disgust propensity, sensitivity and self-directed disgust – in people diagnosed with a broad range of cancers (versus cancer-free controls), and explored their associations with psychological wellbeing.

Design: In a cross-sectional survey design, 107 participants with heterogeneous cancer diagnoses, recruited from cancer charities and support groups, were matched with cancer-free controls by age and gender.

Outcome measures: Measures of the three disgust traits were taken alongside measures of anxiety and depression.

Results: Disgust sensitivity and physical self-disgust were significantly higher in the cancer than control sample, while disgust propensity and behavioural self-disgust were lower. The disgust traits had a different pattern of associations to psychological wellbeing across the two groups, with disgust sensitivity predicting depressive symptoms to a significantly greater extent in the cancer than control group.

Conclusions: People with cancer differ from matched controls in their disgust responses and these responses have significant predictive relationships with aspects of their psychological wellbeing. The results suggest that emotion-based interventions may be useful for improving psychological wellbeing in people with cancer.     

延长哀伤障碍的概念、流行病学和病理机制

延长哀伤障碍是一种由亲近的人去世引发的病理性哀伤反应, 即死亡发生6个月后, 个体对死者的想念影响到了生活各方面, 且社会功能受损, 其最近20年才开始受到临床心理学研究者关注和探讨。本文首先回顾了概念提出及后续发展, 并讨论了其与持续性复杂哀伤相关障碍的区别与联系。随后, 本文综述了其独立的诊断标准、评估工具和流行病学调查、以及与正常哀伤、抑郁症和创伤后应激障碍的区别。接下来, 本文对其病理机制的理论思考和实证研究进行了讨论。最后, 本文指出未来可考察诊断标准的跨文化适用性、丰富病理机制的理论与研究。     

Randomized controlled trial of mindfulness-based stress reduction (MBSR) on posttraumatic growth of Chinese breast cancer survivors

Breast cancer (BC) patients in China suffered from a variety of psychology stress such as perceived stress and anxiety, posttraumatic growth (PTG) as a positive factor could promote their psychology health and quality of life. This study aimed to investigate the efficacy of mindfulness-based stress reduction (MBSR) on promoting PTG, decreasing perceived stress and anxiety of Chinese BC patients. A randomized controlled trial of 60 BC patients (Stages I–III) was conducted. They were randomly divided to the 8-week MBSR group or usual care (UC) group. PTG inventory, Perceived Stress Scale of Chinese version (CPSS) and State Trait Anxiety Inventory (STAI) evaluated the PTG level, perceived stress and anxiety at three times(before intervention-T1, after intervention-T2 and follow up at 3 months-T3). A repeated-measures analysis of variance model was used to compare each outcome measure of two groups at the three times. There was one patient discontinued the intervention and one lose to follow up in MBSR group, finally 58 BC patients completed the research. There was no difference between two groups before the intervention. The results showed significant improvements in MBSR group comparing with the UC group that PTG level was much higher after the 8-week intervention and the follow up (F = 34.73, p < .00). At the same time, CPSS (F = 14.41, p < .00) and STAI (F = 15.24, p < .00) scores were significant decreased at T2 and T3. The results showed that MBSR promoted the level of PTG and decreased perceived stress and anxiety state of Chinese BC patients, and the results persisted at three months after intervention. The research preliminary proved that MBSR was suitable to Chinese BC patients. MBSR should be recommending to BC survivors in China.
