农户生计方式不仅决定了农户的收入,还对区域环境产生了深刻的影响。不同乡村地域类型是影响农户生计资本和生计策略的重要因素。本研究通过参与式农村评估和问卷调查获取于桥水库流域512份农户生计的一手数据,构建了农户生计资本评价指标体系,依据收入结构划分农户生计策略,分析不同乡村地域类型的农户生计资本和生计策略特征,并利用多元回归方程解析生计资本对生计策略的影响。结果表明:流域内农户生计非农化成为普遍现象,纯非农型和非主农辅型生计策略占比分别为29.5%和42.6%。不同生计策略农户的生计资本存在显著差异:纯非农和非主农辅农户的总生计资本、人力资本、社会资本和金融资本显著高于纯农业和农主非辅农户,纯农业和农主非辅农户的自然资本显著高于纯非农型农户。不同乡村地域类型农户的生计资本水平和生计策略选择具有明显差异。经济作物区农户的总生计资本、自然资本显著高于其他地区,传统粮产区的金融资本最低。水库周边区生计策略主要为纯非农型,山地林木区和城镇周边区主要是非主农辅型,传统粮产区和经济作物区主要是纯非农型和非主农辅型,文化旅游区主要是非主农辅型和农主非辅型。人均耕地面积、人均林地面积、耕地破碎化程度、土壤肥力、劳动力占比、家庭人口平均年龄、交通工具和家庭人均收入等指标对农户生计策略选择具有显著影响。不同乡村地域类型生计资本和生计策略差异主要与地理区位、自然资源、社会资源和政策相关。最后,提出基于乡村地域特征的农户生计的针对性优化策略,为促进农户生计可持续发展提供参考。

糖尿病视网膜病变(Dr)是与持续高血糖相关的一种慢性、进行性、潜在危害视力的视网膜微血管疾病,若不能得到及时有效治疗,将严重损害视力,给患者生活带来极大不便。Dr的发生和发展涉及血-视网膜屏障损害、炎症、神经退行性变等多种机制。房水和玻璃体液能直接反映眼球内环境的改变,对眼内病变的进展有很好的提示作用。近年来,眼内液中多种细胞因子在Dr发病过程中的变化、对病程进展的影响及治疗后的改变已得到广泛关注。本文将针对Dr患者眼内液中多种血管生成相关细胞因子,如血管内皮生长因子、胎盘生长因子、半乳糖凝集素1、血管紧张素1(ang1)、ang2及炎症相关细胞因子,如肿瘤坏死因子α、细胞间黏附分子1、血管内皮细胞黏附分子1、单核细胞趋化蛋白1、转化生长因子β、白细胞介素(IL)-1β、IL-6、IL-8、IL-10的变化、糖尿病黄斑水肿和增生性Dr治疗前后细胞因子的变化及其意义进行综述,为探寻Dr新的、个性化的临床治疗方案提供潜在靶点,为改善Dr患者的预后提供理论依据。

目的基于生态位模型分析并预测果洛藏族自治州(果洛州)喜马拉雅旱獭适生区,为今后科学高效的鼠疫宿主监测工作提供理论依据。方法根据现场调查得到的96个喜马拉雅旱獭分布点经纬度及WorldClim网站获取的海拔及19个气候变量,通过最大熵模型(Ma.Ent)和a.cGIS 10.6软件进行建模得出喜马拉雅旱獭在果洛州的适生区,并通过受试者工作特征曲线对模型预测精度进行评价。结果根据Ma.Ent得出该模型的曲线下面积(a.C)值=0.928。排名前5位的因素贡献度从高到低依次为最干燥月份降水量(35.7%)、温度季节性变化(26.3%)、季节性降水(20.5%)、昼夜温差月均值(10.2%)、海拔(7.3%)。各因素在模型中的响应曲线分析得出,在昼夜温差月均值为14.7℃、温度季节性变化为800、最干燥月份降水量为2.4 mm、季节性降水为95、海拔为3720 m时各因素的响应曲线达到最高值。预测结果显示,果洛州喜马拉雅旱獭高适生区面积达2445.24 km^(2),中适生区面积达4240.76 km^(2),主要位于玛沁县、甘德县境内。结论最大熵模型预测结果可靠,与实际情况相符,为今后鼠疫监测工作提供了科学高效的理论依据;玛沁、甘德县喜马拉雅旱獭高、中适生区分布区域占比较高,应加强对该区域的监测。

Gra.hene oxide is a.very high ca.a.ity a.sorbent due to its functiona. groups a.d π-π intera.tions with other compounds. a.sorption ca.a.ity of gra.hene oxide, however, ca. be further enha.ced by ha.ing synergistic effects through the use of mixed-ma.rix composite. In this study, silica.decora.ed gra.hene oxide(SGO) wa. used a. a.high-efficiency a.sorbent to remove Congo red(Cr) a.d Ca.mium(Ⅱ) from a.ueous solutions. The effects of solution initia. concentra.ion(20 to 120 mg/l), solution pH(pH 2 to 7), a.sorption dura.ion(0 to 140 min) a.d tempera.ure(298 to 323 K) were mea.ured in order to optimize the a.sorption conditions using the SGO a.sorbent. Morphologica. a.a.ysis indica.ed tha. the silica.na.opa.ticles could be dispersed uniformly on the gra.hene oxide surfa.es. The ma.imum ca.a.ities of a.sorbent for effective remova. of Cd(Ⅱ) a.d Cr were 43.45 a.d 333.33 mg/g ba.ed on Freundlich a.d Langmuir isotherms, respectively. Langmuir a.d Freundlich isotherms displa.ed the highest va.ues of Q ma. for Cr a.d Cd(Ⅱ) a.sorption in this study, which indica.ed monola.er a.sorption of Cr a.d multila.er a.sorption of Cd(II) onto the SGO, respectively. Thermodyna.ic study showed tha. the entha.py( H) a.d Gibbs free energy( G) va.ues of the a.sorption process for both polluta.ts were nega.ive, suggesting tha. the process wa. sponta.eous a.d exothermic in na.ure. This study showed a.tive sites of SGO( π-π, hydroxyl, ca.boxyl, ketone, sila.e-ba.ed functiona. groups) contributed to a. enormous enha.cement in simulta.eous remova. of Cr a.d Cd(Ⅱ) from a. a.ueous solu-tion, Therefore, SGO ca. be considered a. a.promising a.sorbent for future wa.er pollution control a.d remova. of ha.a.dous ma.eria.s from a.ueous solutions.
