Zhongguo shiyan zhenduanxue, 2015 目的分析变应性鼻炎血清特异性IgE（sIgE）及皮肤点刺实验与临床症状的相关性。方法选择80例变应性鼻炎患者,检测sIgE,同时进行标准化皮肤点刺试验,同期对患者进行症状进行评分,分析sIgE水平与皮肤点刺试验阳性程度的相关性及其与临床症状的相关性。结果1sIgE阳性强度与皮肤点刺试验阳性强度具有相关性（Kappa=0.558,P0.05）。结论 sIgE阳性强度、皮肤点刺试验阳性强度与临床症状无相关性,但两种检查方式具有一致性,对诊断、鉴别诊断变应性鼻炎具有较高的临床价值。

Wildlife Letters, EarlyView.We used automated behavioral response systems (ABRs) to assess invasive wild pig (Sus scrofa) behavioral response to four auditory playbacks: humans, coyote vocalizations (Canis latrans), pigs in distress, and barred owl (Strix varia) calls. Wild pigs had a significant flight response to human playbacks, but 68% of pigs did not flee.

Wildlife Letters, EarlyView.The study explores how beavers (Castor spp.) affect endangered freshwater pearl mussels (Margaritifera margaritifera) in European rivers. Beaver dams can harm small, fragmented mussel populations by reducing flow, increasing sediment, and potentially limiting host fish movement, while larger populations may benefit from improved bed stability and ...

急性脑梗死体积与空腹血糖、血清胰岛素及胰岛素抵抗的相关性研究
Zhongguo shiyan zhenduanxue, 2000 目的全面系统地观察分析空腹血糖（ＦＰＧ）、血清胰岛素（ＦＩＮＳ）、胰岛素抵抗性（ＩＲ）与急性脑梗死体积的相 关性及其意义。方法同步采集急性脑梗死体积（ＣＴ多田氏法计算）、ＦＰＧ（特异性葡萄糖氧化酶法）、ＦＩＮＳ（放射免疫法）、 ＩＲ［Ｉｎ（ １／ＦＰＧ×ＦＩＮＳ）法］的数值，并与急性脑外伤组及正常对照组比较，组间两样本均数比较采用计量资料 ｔ检验，两变量 间关系采用直线相关分析。结果ＦＰＧ、ＦＩＮＳ、ＩＲ在急性脑梗死时与急性脑外伤时一样，与正常对照组相比明显升高 （ｐ＜ ０．０１ ...

Multi‐gradient warming reshapes functional traits and adaptive responses of alpine meadow plants
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant functional traits in alpine meadows are critical indicators of ecosystem responses to climate warming, yet dynamic changes in trait networks across warming gradients and their consequences for community functions remain poorly understood.

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...
