脑淀粉样血管病发病机制的研究进展

脑淀粉样血管病（cerebral amyloid angiopathy，CAA）的主要致病物质是β淀粉样蛋白，其 产生异常、清除障碍导致异常沉积，引起管壁破坏、管腔狭窄等病理变化，最终导致CAA。目前CAA的 具体发病机制尚不清楚，涉及的成分复杂。本文介绍了β淀粉样蛋白产生及清除的三种过程及其平 衡破坏的后续效应和主要影响因素，同时从病因分类的角度阐明CAA的类型。     

Real-World Palbociclib Use in HR+/HER2− Advanced Breast Cancer in Canada: The IRIS Study

Background: Palbociclib is a selective cyclin-dependent kinase (CDK) 4/6 inhibitor used in combination with aromatase inhibitors or fulvestrant for patients with hormone receptor-positive (HR+) human epidermal growth factor receptor 2 (HER2)-negative advanced/metastatic breast cancer (ABC/MBC). Palbociclib was the first CDK 4/6 inhibitor approved for HR+/HER2− ABC/MBC treatment in Canada in combination with letrozole (P+L) as an initial endocrine-based therapy (approved March 2016), or with fulvestrant (P+F) following disease progression after prior endocrine therapy (approved May 2017). The Ibrance Real World Insights (IRIS) study ({"type":"clinical-trial","attrs":{"text":"NCT03159195","term_id":"NCT03159195"}}NCT03159195) collected real-world outcomes data for palbociclib-treated patients in several countries, including Canada. Methods: This retrospective chart review included women with HR+/HER2− ABC/MBC receiving P+L or P+F in Canada. Physicians reviewed medical records for up to 14 patients, abstracting demographic and clinical characteristics, treatment patterns, and clinical outcomes. Progression-free rates (PFRs) and survival rates (SRs) at 6, 12, 18, and 24 months were estimated via Kaplan–Meier analysis. Results: Thirty-three physicians examined medical records for 247 patients (P+L, n = 214; P+F, n = 33). Median follow-up was 8.8 months for P+L and 7.0 months for P+F. Most patients were initiated on palbociclib 125 mg/d (P+L, 90.2%; P+F, 84.8%). Doses were reduced in 16.6% of P+L and 14.3% of P+F patients initiating palbociclib at 125 mg/d. The PFR for P+L was 90.3% at 12 months and 78.2% at 18 months; corresponding SRs were 95.6% and 93.0%. For P+F, 6-month PFR was 91.0%; 12-month SR was 100.0%. Conclusions: Dose reduction rates were low and PFR and SR were high in this Canadian real-world assessment of P+L and P+F treatments, suggesting that palbociclib combinations are well tolerated and effective.     

辨体-辨病-辨证诊疗模式在慢性病防治中的应用策略

依据中国防治慢性病中长期规划（2017-2025年），按照国医大师王琦教授倡导的"辨体-辨病-辨证诊疗模式"，提出慢性病"3+4+3"防治路向：面向三类人群（一般、高危、患病人群），朝向四种状态（无病、病前、病中、病后状态），指向三辨模式（辨体-辨病-辨证诊疗模式）。进而探讨其应用策略：对于一般人群无病状态——辨体养生，固本防病；对于高危人群病前状态——辨体干预，治本救萌；针对患病人群病中状态——"三辨"施治，标本兼顾；针对患病人群病后状态——辨体调理，固本防复。文中结合案例加以佐证，具有临床指导价值。

A Review of Machine Learning Techniques for Keratoconus Detection and Refractive Surgery Screening

ABSTRACT

Various machine learning techniques have been developed for keratoconus detection and refractive surgery screening. These techniques utilize inputs from a range of corneal imaging devices and are built with automated decision trees, support vector machines, and various types of neural networks. In general, these techniques demonstrate very good differentiation of normal and keratoconic eyes, as well as good differentiation of normal and form fruste keratoconus. However, it is difficult to directly compare these studies, as keratoconus represents a wide spectrum of disease. More importantly, no public dataset exists for research purposes. Despite these challenges, machine learning in keratoconus detection and refractive surgery screening is a burgeoning field of study, with significant potential for continued advancement as imaging devices and techniques become more sophisticated.     

Challenges for Research into Military Investigations

In cases of suspected violations of rules, regulations or the law by armed forces personnel, investigations are invariably mandatory. Military investigations differ from well-researched civilian criminal investigations. Differing from civilian police detectives, most military investigators – as disciplinary supervisors and military police personnel – have a number of tasks to accomplish, which include leading in combat and ensuring military readiness. Military investigations can lead to substantive negative or positive consequences for military readiness, including mental health, unit cohesion and subjective legal certainty. This impact on unit cohesion and mental health is influenced by any prior history of distress or trauma; military investigations are often preceded by contravention of internal disciplinary acts, complaints and traumatic events. This study explores factors in the differing military and legal systems of Germany and the United Kingdom (UK) that might help military personnel to successfully conduct investigations while ensuring deployment readiness and maintaining human rights.     

冠心病从体质干预与通调阴维脉论治

冠心病西医药物治疗虽可控制发作，但有时不能延缓病情发展，非药物治疗过程中围手术期多风险，易病情反复。中医辨证治疗存在证型不统一且证候消失后难根治的问题。倪诚教授秉承王琦国医大师"体病相关""体质可调"理论，认为血瘀体质、痰湿体质、气虚体质是冠心病的发病基础，瘀阻阴维是冠心病的病机要点，祛瘀化痰、补气通维是冠心病的主要治法，临床上自创通维止痛汤，取得良好疗效。
