背景中国全科医生越来越期望能够识别和预防抑郁障碍,但其接受的心理健康培训有限,社区卫生服务中心(CHCs)也缺乏针对抑郁障碍的诊断和服务规范。WHO《心理健康差距干预指南》第2版(mhGAP-IG.v2)是为非心理健康专业人员提供的决策支持工具,可用于评估、管理、随访精神障碍、神经疾病及物质使用障碍患者。鉴于mhGAP-IG.v2的通用性,其在中国的应用应根据抑郁障碍在不同文化下的差异性和中国心理健康系统特点进行调整。方法开展两轮基于网络的德尔菲(Delphi)调查。邀请来自深圳市的全科医生小组对mhGAP-IG.v2中涉及抑郁障碍的199条表述进行五分制的赞同程度打分,即“如要把该表述用在深圳市,是否赞同调整其内容和结构”。如果>80%的全科医生“有些/肯定赞同”调整某表述,则视为全科医生对调整该表述达成共识;如果>80%的全科医生“有些/肯定不赞同”调整某表述,则视为全科医生对不调整该表述达成共识。结果全科医生对79%的表述达成了需要调整的共识,平均得分为4.26分,即全科医生“有些赞同”对mh GAP-IG.v2中涉及抑郁障碍的相关表述进行调整。具体调整建议包括:抑郁评估方法应考虑更广泛的抑郁症状,并考虑病情的发展阶段;增加抑郁筛查工具的使用指南;明确全科医生的作用,以及家庭参与和跨部门服务的转诊途径;药物治疗建议应与中国用药规范保持一致;指南所有章节要强调预防自杀;情境化健康教育;强调“以人为本”的服务方法。全科医生认为,应维持mhGAP-IG.v2中对经历抑郁发作的双相障碍患者的诊断和治疗建议。结论对mhGAP-IG.v2抑郁部分的调整研究反映出对指南的评估应考虑文化和国情背景,包括中国特色的初级卫生保健系统、健康优先领域、治疗可得性,以及多样化的社会心理教育需要。调整后的mhGAP-IG.v2可以给中国全科医学教育和全科医疗服务提供参考,也可以为其他国家的非精神病学专业人员开展心理健康服务提供有益借鉴。

象鸟,澳大利亚的巨型丑小鸭

作者： harry Pettit 王怡霖(选译) 不详

世界上最大的鸟有一头牛那么重,它5万年前生活在澳大利亚。不会飞的史氏雷啸鸟用两条后腿缓慢前行。它是一个灭绝的生物群mihirungs(原住民语“巨鸟”的意思)中最大的一个,这个生物群的名字来源于土著人对巨型鸟的称呼。

Objective To learn the effect of omemtum transposition to the brain of patients with Alzheimer’s disease. Methods Ten consecutive patients, aged 58-81 years old, underwent graft of their elongated pedicled omentum onto their left frontal-temperal-parietal cerebral cortex. Those patients, who had more than five years of dementia with low mini mental-state examination (MMsE) scores of 2-15, were diagnosed by a neurologist. All subjects underwent single photon evoked computer tomography (sPECT) pre- and post-operatively. sPECT results were analyzed semi-quantitatively by calculation of the left/right radioactivity counts symmetry index (si). The patients were followed up to one year. The outcome was evaluated by the neurologist with a modified scale of activities of daily living (mADL) as well as the MMsE. Results Three months following the surgery, the si of sPECT increased from (98.7±1.9)% to (103.9±2.3)% (P=0.0307). The neurological and neuropsychological testing scores increased insignificantly during the follow-up period. By the one year, the MMsE score rose from 8.7±1.4 to 10.7±1.8(P>0.05), while the mADL from 13.3±1.8 to 16.9±2.0 (P>0.05). One of the patients suffered a heart attack, two had epileptic episodes postoperatively. Conclusion We believe that omental transposition to the brain augments cerebral blood flow, which might be helpful to decelerate the processing of Alzheimer’s disease. However, it is still a potentially risky procedure for the elderly.

A new approach to model viscosity in the conservation of momentum equations is presented and discussed. Coefficient of viscosity is modeled in such a way that it reaches asymptotically to infinity at the solid boundary but still yields a finite value for the shear stress at the solid wall. Basic objective of this research is to show that certain combinations of higher order normal velocity gradients become zero at the solid boundary. Malled solutions for the Couette flow and Poiseuille flow between two parallel plates are obtained by modeling the coefficient of viscosity in a novel way. Also, viscous drag computed by our model is expected to yield higher values than the values predicted by the existing models, which matches closely to the experimental data.
