Background:Eucommia ulmoides oliv. is a medicinal plant native to China, with its bark (Eucommiae Cortex) traditionally being used for medicinal purposes. Previous research has shown that Eucommia male flowers can exert anti-inflammatory, analgesic, antibacterial, and other pharmacological effects, including immune regulation. This study explored the anti-inflammatory effects of the 70% ethanol extract of male flowers (EF) of E. ulmoides in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and LPS-administered ***:Cytotoxicity of EF for RAW 264.7 cells was investigated using Cell Counting Kit-8. The production of proinflammatory mediators, nitric oxide (NO), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 was determined using enzyme-linked immunosorbent assays. IL-17, IL-23, and IL-10 mRNA levels were determined using quantitative real-time polymerase chain reaction. Activation of the nuclear factor (NF)-κB pathway in RAW 264.7 cells was investigated via Western blotting. In vivo antiinflammatory effects of EF were studied in an LPS-induced acute inflammation mouse model by analyzing lung tissue histopathology, serum TNF-α and IL-6 levels, and myeloperoxidase (MPO) activity in lung ***:EF showed no significant cytotoxicity at concentrations from 10 to 60 μg/mL (cell viability > 80%) in the CCK-8 cell viability assay. EF inhibited the RAW 264.7 cell proliferation (EF 60 μg/mL, 120 μg/mL, and 250 μg/mL vs. negative control: 87.31±2.39% vs. 100.00±2.50%, P=0.001;79.01±2.56 vs. 100.00±2.50%, P<0.001;and 64.83±2.50 vs. 100.00±2.50%, P<0.001), suppressed NO (EF 20 μg/mL and 30 μg/mL vs. LPS only, 288.81±38.01 vs. 447.68±19.07 μmol/L, P=0.004;and 158.80±45.14 vs. 447.68±19.07 μmol/L, P<0.001), TNF-α (LPS+EF vs. LPS only, 210.20±13.85 vs. 577.70±5.35 pg/mL, P<0.001), IL-1β (LPS+EF vs. LPS only, 193.30±10.80 vs. 411.03±42.28 pg/mL, P<0.001), and IL-6 (LPS+EF vs. LPS only, 149.67±11.60 vs. 524.80±6.24 pg/mL, P<0.001) secretion, and downregul

[Objective] This research was to study the correlation regional climatic characteristics and changing geographic distribution of Populus euphratica oliv. (Salicaceae), as well as the adaption of Populus euphratica oliv. to the climatic environment. [Method] The climatic characteristics, water source, groundwater and soil type in the distribution regions of Populus euphratica oliv. and the effect of long-term human activities were comprehensively analyzed based an overview of Populus euphratica oliv. and its distribution. [Result] Specific regional climatic characteristics and long term human activities are the principle determinants for the growth of Populus euphratica oliv. The change of leaf shape is a distinct feature of Populus euphratica oliv. in adapting to the climatic environment. Populus euphratica oliv. withstands various environmental stresses by means of in vivo synthesis, transport and conversion of secondary phenolic metabolites. Effective protection and rehabilitation measures, and ecological water transport have obvious effect on the restoration and reconstruction of damaged ecological environment of Populus euphratica oasis. [Conclusion] This study is of great significance for the restoration of ecological environment in the arid inland regions, north-west China.

目的研究杜仲及其盐制品对去卵巢大鼠骨质疏松症的治疗作用,并探讨盐制对其治疗作用的影响。方法 40只SD雌性大鼠分为伪手术组、模型对照组、杜仲生品治疗组和杜仲盐制品治疗组,除假手术组施行假手术外,其余均行手术彻底摘除卵巢,术后4周开始杜仲生品及盐制品水提液灌胃给药(4.0 g/kg·d),实验过程称体质量,连续给药12周后,颈动脉取血,测定血钙(S-Ca)、血磷(S-P)含量,ELISA试剂盒双抗体夹心法测定血清碱性磷酸酶(ALP)、骨钙素(OCN)、雌二醇(E2)含量;动物处死后剥取完整子宫称重,采用HE染色法进行子宫病理学检查,剥离双侧股骨,双能X射线衍射法测定大鼠股骨骨密度。HE染色法观察股骨骨小梁形态和成骨细胞数量,micro-CT扫描观察股骨骨小梁微体系结构。结果杜仲生品及盐制品能有效抑制去卵巢所致的大鼠体重增加,升高血清钙、雌二醇的含量,降低血磷、碱性磷酸酶和骨钙素的含量。增加大鼠股骨骨密度,改善股骨骨小梁微体系结构,增加股骨骨小梁成骨细胞数量,且长期用药对子宫无明显刺激作用。结论杜仲生品及盐制品对于大鼠去卵巢所引起的骨质疏松症有良好治疗作用,且盐制品效果优于生品。

水青树（Tetracentron sinense oliv.）扦插不易生根，但经ABT1号生根粉不同浓度处理后，生根率均有提高，以浓度200×10-6处理2h生根率最高，可达56．0％；同时生根数、根长和新梢长分别为10条、9cm和4．5cm。适宜的环境湿度和生根温度是嫩枝扦插成活的关键，全光照喷雾能满足插穗生根所需的湿度并保证充分的光照，在一定程度上保证了插穗生根所需的生长环境，因而有利于生根。
