OBJECTIVE: To investigate blood pressure rhythm(BPR)in Yin deficiency syndrome of hypertension(YDSH)patients and develop a random forest model for predicting ***: Our study was consistent with technical processes and specification for developing guidelines of Evidence-based Chinese medicine clinical practice(T/CACM 1032-2017). We enrolled 234 patients who had been diagnosed with primary hypertension without antihypertensive medications prior to the enrollment. All participants were divided into Yin deficiency group(YX, n = 74) and non-Yin deficiency group(NYX, n = 160).Participants were professionally grouped by three experienced chief Traditional Chinese Medicine(TCM)physicians according to four examinations(i.e.,inspection, listening and smelling, inquiry and palpation).We collected data on 24 h ambulatory blood pressure monitoring(ABPM) and YDSH rating scale. We divided 24 h of a day into 12 two-hour periods [Chen-Shi(7:00-9:00), Si-Shi(9:00-11:00), Wu-Shi(11:00-13:00), Wei-Shi(13:00-15:00), Shen-Shi(15:00-17:00), You-Shi(17:00-19:00), xu-Shi(19:00-21:00), Hai-Shi(21:00-23:00), ZiShi(23:00-1:00), Chou-Shi(1:00-3:00), Yin-Shi(3:00-5:00), Mao-Shi(5:00-7:00)] according to the theory of “midnight-midday ebb flow”. We used random forest to build the diagnostic model of YDSH, with whether it was Yin deficiency syndrome as the outcome. RESULTS: Compared with NYX group, YX group had more female participants with older age, lower waist circumference, body mass index(BMI), diastolic blood pressure(DBP), and smoking and drinking rate(all P < 0.05). The YDSH rating scores of YX group [28.5(21.0-36.0)] were significantly higher than NYX group [13.0(8.0-22.0)](P < 0.001), and the typical symptoms of YX group included vexing heat in the chest, palms and soles, dizziness, dry eyes, string-like and fine pulse, soreness and weakness of lumbus and knees, palpitations, reddened cheeks, and tinnitus(all P < 0.05). The ratio of non-dipper hypertension in YX group was higher t

[目的]为探究紫色土区不同农林复合模式土壤入渗特征及其影响因素。[方法]通过野外调查和室内试验,分析紫色土区无作物(CK)、花生(HS)、花椒(HJ)、花生+花椒(HS+HJ)4种农林复合模式下土壤物理性质与入渗过程变化特征,评价了3种土壤入渗模型(Kostiakov、Horton、Philip)的适用性。[结果](1)HJ模式下土壤总孔隙度与CK、HS+HJ模式差异不显著,但显著高于HS模式(p<0.05);CK和HS模式的土壤抗剪强度差异不显著,但均显著高于HJ模式和HS+HJ模式(p<0.05);各模式下土壤容重、含水率、温度、斥水性、紧实度、土壤硬度差异均显著(p<0.05)。(2)4种模式土壤水分入渗过程差异较大,CK和HS下土壤水分入渗在20 min左右进入稳渗阶段,而HJ和HS+HJ模式下土壤入渗分别在70,80 min左右进入稳渗阶段。HS+HJ模式的土壤稳定入渗率分别比CK、HS、HJ模式高出162%,140%,82%(p<0.05)。(3)与Horton和Philip模型相比,Kostiakov模型拟合入渗过程的效果最佳(决定系数R^(2)=0.933~0.991);Horton模型拟合效果相对较差(R^(2)=0.849~0.979)。(4)相关性与多元线性回归分析发现,土壤总孔隙度与土壤抗剪强度是影响土壤入渗的关键因素。[结论]研究结果为紫色土区农林复合模式的优化选择提供科学依据。

为明确三峡水库汉丰湖叶绿素a(Chl.a)的主要影响因素,分析了汉丰湖2018—2021年的Chl.a、pH、水温、透明度以及氮、磷营养盐等水质指标的变化情况,探讨了Chl.a与其余水质指标的相关性,并应用结构方程模型解析了Chl.a的关键影响因素。结果表明,汉丰湖水体Chl.a浓度在0.04~68.58μg/L之间变化,水温在9.62~32.10℃之间,pH在6.75~9.81之间,总氮、溶解性氮、总磷、溶解性磷的变化范围分别为0.58~4.68、0.25~3.99、0.02~0.76、0.01~0.44 mg/L。Chl.a浓度与水温、pH、总磷和总固体悬浮物呈显著正相关,与透明度、溶解性氮、碱度、亚硝态氮、硝态氮呈极显著负相关。结构方程模型结果显示,影响Chl.a浓度的因子中理化因子的路径系数为0.68,营养物质的路径系数为0.16,这表明影响Chl.a浓度的因子以理化因子为主,营养物质的作用相对较小。同时,理化因子通过营养盐间接影响Chl.a浓度(路径系数为-0.04)。各理化因子中,水温和pH的路径系数分别为0.51和0.41,水温是理化因子的主要表征指标;在营养盐指标中,总磷和溶解性磷的路径系数分别为0.82和0.71,而总氮的路径系数为0.36,说明磷是汉丰湖的限制性营养元素。
