染色内镜和放大内镜技术是提高早期大肠癌诊治水平的重要手段

应用常规内镜技术难以发现大肠平坦型病变和凹陷型病变。近年来染色内镜和放大内镜技术已经发展成熟,在国外已获广泛应用,可以发现大肠微小病变和早期大肠癌。应用腺管开口分型方法可以预测肿瘤病变的组织学类型及肿瘤的浸润深度,据此可确定行内镜下粘膜剥离术或分片粘膜剥离术将肿瘤切除,抑或行外科手术治疗。在当前我国的胃肠内镜医疗界,应广泛开展染色内镜和放大内镜的临床应用,以早期发现大肠病变,提高我国大肠癌的内镜诊治水平。     

On the Edge: a drama‐based mental health education programme on early psychosis for schools

Aims: On the Edge is a mental health education programme designed to support early intervention by increasing knowledge and understanding of early psychosis, reducing the stigma associated with mental health issues and improving awareness of avenues of help. The target audience was young people aged 14–22 years in schools and colleges. Methods: An interactive drama programme was developed through collaborative working across psychiatry, applied drama and those with direct experience of psychosis. A national tour engaged 2500 students in 71 performances that took place in 51 schools and colleges. The programme was evaluated against its aims with data collected both during and after the tour. Results: Quantitative and qualitative evaluation found significant gains with respect to all three aims. Thirty‐one schools developed supportive links with local mental health services. Conclusions: This programme shows the value and effectiveness of delivering health education on early psychosis through the medium of applied drama, and offers a model for a programme that can be incorporated into early intervention services. Lessons learned through delivering this programme are a valuable contribution towards future developments of mental health education programmes for schools.     

217例早期胃癌扩大胃切除与淋巴结清除术的回顾分析

目的评价早期胃癌不同扩大手术的实际意义，以选择合理的胃切除和淋巴结清除范围。方法以临床病理资料完整、施行规范D2及扩大手术的217例早期胃癌患者为研究对象。分析施行不同扩大手术的原因、淋巴结清除的必要性及第Ⅱ站淋巴结转移与临床病理因素的相关性。结果胃上部癌行全胃切除术6例，No．5、6淋巴结均未见转移；联合脾、脾动脉切除2例，No．10、11p、11d淋巴结均未见转移；胃下部癌联合横结肠系膜切除3例，No．15淋巴结未见转移。以上病例术中多数误认为进展期胃癌而扩大了胃切除或淋巴结清除范围，手术时间长，术中失血较多。胃下部癌清除的第Ⅱ站淋巴结中No．11p、12a、14v均未见转移；黏膜下癌（sm癌）中，No．7、8a淋巴结转移率明显高于黏膜内癌（m癌）（P〈0．05）；淋巴管癌栓阳性者No．7淋巴结转移较阴性者明显增多（P〈0．001），No．1、13淋巴结转移仅出现在淋巴结转移高危病例（sm、癌灶大于3．0cm、凹陷型，淋巴管癌栓阳性）。结论早期胃癌不需施行淋巴结扩大清除术和联合脏器切除。早期胃上部癌不需施行全胃切除术。早期胃下部癌中No．11p、12a、14v淋巴结不需清除．但对胃下部癌淋巴结转移高危病例，应行标准D2淋巴结清除术。     

Current concept and future research directions of mild cognitive impairment

Alzheimer's disease (AD) generally begins with mild memory problems which occur in an insidious manner and progresses to the development of multiple cognitive impairments. There is a ‘gray’ area between what is classified as ‘normal’ and what is classified as ‘dementia’, currently called mild cognitive impairment (MCI). In this article, a case of MCI is described, and the diagnosis, assessment, subclassification (pre‐Alzheimer type and white matter lesion type) and future therapeutic plans for MCI are reviewed.     

The Effect of Sirolimus Therapy on Vaccine Responses in Transplant Recipients

Different immunosuppressant regimens vary in their effects on antibody responses to vaccination. The combination of prednisolone and azathioprine has only a minor effect, whereas the addition of ciclosporin attenuates protective antibody responses to influenza vaccination. The effect of sirolimus, a new immunosuppressant, on vaccine responses has been little studied. Thirty-two hepatic or renal transplant patients randomized to calcineurin inhibitor-based or sirolimus-based immunosuppression were vaccinated against influenza and pneumococcus. Following tri-valent influenza vaccination, a similar rise in antibody titer occurred in sirolimus and calcineurin inhibitor (CNI) treated patients, though sirolimus treated patients developed a 'protective' titer to more influenza antigens. The pneumococcal polysaccharide vaccine was equally effective in both groups. Hence, vaccination guidelines in place for CNI treated patients are likely to be appropriate for transplant recipients maintained on sirolimus.     

抗神经元抗体对副肿瘤综合征早期诊断的临床意义

目的 探讨抗神经元抗体抗-Hu、抗-Yo、抗-Ri抗体的检测与副肿瘤综合征早期诊断的关系。方法 采用蛋白免疫印迹分析(Western Blot)法对12例确诊为副肿瘤综合症(PNS)的患者血清及32例非PNS血清进行检测。结果 12例确诊患者血清中检测到一项或多项抗体阳性;PNS患者血清中抗-Hu、抗-Yo、抗-Ri抗体的阳性率高于非PNS对照组,差异有极显著性意义(P<0.01);正常对照组血清抗-Hu,抗-Yo,抗-Ri抗体全部为阴性。结论 抗神经元抗体抗-Hu、抗-Yo、抗-Ri抗体可作为PNS早期诊断及确诊的指标。     

Sonographic diagnosis of early recurrence after inguinal herniorrhaphy: Potential pitfalls

Three patients who presented with scrotal swelling within a few days of inguinal herniorrhaphy are reported. Ultrasonography scans performed in these patients all demonstrated features suspicious of recurrence of hernia. One patient underwent surgical exploration, which revealed only a scrotal haematoma without evidence of recurrent hernia. The other two patients were managed conservatively because clinically the swellings were regarded to be more compatible with haematoma. Both patients had subsequent resolution of the scrotal swelling with no clinical evidence of recurrence of hernia on follow‐up. It is concluded that sonographic diagnosis of recurrence of hernia shortly after inguinal herniorrhaphy can occasionally be misleading.     

Long-term effectiveness and quality of life improvement in entacapone-treated Parkinson's disease patients: the effects of an early therapeutic intervention

To evaluate the long-term effects of entacapone on both mean daily 'on' time and health-related quality of life (QoL) in patients with Parkinson's disease (PD) experiencing 'end-of-dose' motor fluctuations and the benefits of an early therapeutic intervention. A prospective, multicenter, observational, 12-month study was performed with an initial 3-month intervention phase, consisting of a phone call to half of the patients from randomly selected investigators to assess if dose adjustment was necessary. Effectiveness was determined by home diaries ('on' time), subscales II and III of the Unified Parkinson's Disease Rating Scale (UPDRS), and the Parkinson's Disease Questionnaire (PDQ-8). After 3 months of treatment, 4.0% of the intervention group patients discontinued the study, versus 18.4% in the control group ( P  < 0.01). The improvement in 'on' time was significantly increased since the 3-month visit (21%, P  < 0.0001) until the end of the study (23% at 12 months, P  < 0.0001). Entacapone also induced significant reductions in the UPDRS scores for subscales II and III and in the PDQ-8 score. 11.2% of patients experienced at least one adverse reaction. This study confirms the effectiveness of entacapone in reducing motor fluctuations by increasing 'on' time, and in improving QoL of PD patients. An early adjustment of entacapone and levodopa doses reduces the number of treatment discontinuations during the first months of treatment.
