脑白质高信号的非传统血管危险因素研究进展 Advances in Non-traditional Vascular Risk Factors for Cerebral White Matter Hyperintensity

open access: yesZhongguo cuzhong zazhi, 2019
血管源性脑白质高信号(white matter hyperintensity,WMH)是脑小血管病的典型影像学征 象之一。临床上有一部分WMH病例无高血压、糖尿病等传统血管危险因素,却伴有偏头痛、晕厥、睡 眠呼吸暂停、睡眠障碍、直立性低血压等非传统危险因素或临床症状。本文对研究WMH与非传统血 管危险因素关系的文献进行整理和总结。对非传统血管危险因素的深入研究有助于进一步认识WMH 的潜在机制。针对非传统血管危险因素的控制和治疗可能有助于WMH的预防和治疗。 Abstract: Cerebral

首次青年缺血性卒中短期预后不良危险因素分析 Risk Factors for Short-term Poor Prognosis in Young Patients with First-ever Ischemic Stroke

open access: yesZhongguo cuzhong zazhi, 2022
目的 分析首次青年缺血性卒中患者出院、发病90d预后不良的相关危险因素。 方法 回顾性纳入18~45岁、发病72 h内的首次缺血性卒中患者,收集患者人口学信息、血管危险因素、实验室检查结果、入院和出院时NIHSS,以出院时和发病90 d mRS≥2分为预后不良,分别比较预后不良组和预后良好组危险因素的差异和病因分型特点,并采用多因素logistic回归分析出院和90 d预后不良的独立危险因素。 结果 研究共纳入691例首次青年缺血性卒中患者,出院预后不良234例(33.9%),90 ...

Calibration of the species threat abatement and restoration metric's threat abatement component in a Costa Rican landscape

open access: yesConservation Biology, Volume 40, Issue 3, June 2026.
Abstract Achieving global conservation policy goals requires the ability to set and measure progress toward science‐based targets for biodiversity. The species threat abatement and restoration (STAR) metric was developed to enable actors to set science‐based targets for species.

Hobbyist preferences for pet freshwater turtles

open access: yesConservation Biology, Volume 40, Issue 2, April 2026.
Abstract The burgeoning pet trade is a primary threat to wild freshwater turtles worldwide. Although the risks from commercial exploitation of turtles have been discussed widely, there is little empirical research on preferences for pet turtles from a hobbyists’ perspective.

脑小血管病与代谢:危险因素、治疗靶点和未来方向Cerebral Small Vessel Disease and Metabolism: Risk Factors, Therapeutic Targets, and Future Directions

open access: yesZhongguo cuzhong zazhi
明确脑小血管病(cerebral small vessel disease,CSVD)的代谢危险因素并进行及时、系统的管控至关重要。目前残余代谢危险因素与CSVD的相关性尚存争议,而靶向危险因素治疗CSVD的临床效果尚缺乏循证依据。本文综合分析炎症、肠道菌群紊乱、高同型半胱氨酸血症及高尿酸血症等残余代谢危险因素与CSVD发生、发展的相关性,进一步探讨靶向代谢危险因素的潜在治疗方案,强调代谢组学在CSVD新型代谢生物标志物发现和风险预测模型建立中的重要作用,并展望未来研究方向,为CSVD的早期诊断 ...

Spatial segregation and bycatch risk as potential drivers of population trends of wandering albatrosses at South Georgia

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Spatial segregation in at‐sea distribution is frequently observed in seabirds and can have important implications for conservation and management. Globally, many albatross and petrel populations are declining due to bycatch in fisheries. In South Georgia, the decrease in wandering albatrosses (Diomedea exulans) differs among breeding sites ...

Genetic Confirmations of Dwarf Lemurs Across Madagascar Highlights Complex Biogeographic Patterns 马达加斯加全境鼠狐猴的遗传确认揭示了复杂的生物地理模式

open access: yesIntegrative Conservation, Volume 4, Issue 4, Page 665-674, December 2025.
Using a diagnostic mitochondrial marker gene, we document the presence of furry‐eared dwarf lemurs, a species known from Madagascar's eastern montane rainforests, in several forest fragments across the island's central highlands. These findings raise new questions about when this species colonized these sites, how they tolerate these changing and ...
