Effect of EM Bokashi application on control of secondary soil salinization

In order to ameliorate saline-alkaline soil, EM Bokashi has been applied to rice production in conjunction with subdrainage in Ningxia Autonomous Region and Zhejiang Province. The preliminary results can be summarized as follows： EM Bokashi can increase soil organic matter content, improve soil porosity and permeability, and raise the soil＇s levels of available nutrients; and EM Bokashi combined with subdrainage treatment is more effective in controlling secondary soil salinization and raising the grain yield and quality than other treatments. The results suggest that EM Bokashi can reduce the necessary amount of chemical fertilizer application, thereby improving the agricultural environment, and that the introduction of EM Bokashi into systems of secondary soil salinization control systems has resulted in significant benefits.     

BMP3 Alone and Together with TGF-β Promote the Differentiation of Human Mesenchymal Stem Cells into a Nucleus Pulposus-Like Phenotype

Human mesenchymal stem cells (MSCs) have the potential to differentiate into nucleus pulposus (NP)-like cells under specific stimulatory conditions. Thus far, the effects of bone morphogenetic protein 3 (BMP3) and the cocktail effects of BMP3 and transforming growth factor (TGF)-β on MSC proliferation and differentiation remain obscure. Therefore, this study was designed to clarify these unknowns. MSCs were cultured with various gradients of BMP3 and BMP3/TGF-β, and compared with cultures in basal and TGF-β media. Cell proliferation, glycosaminoglycan (GAG) content, gene expression, and signaling proteins were measured to assess the effects of BMP3 and BMP3/TGF-β on MSCs. Cell number and GAG content increased upon the addition of BMP3 in a dose-dependent manner. The expression of COL2A1, ACAN, SOX9, and KRT19 increased following induction with BMP3 and TGF-β, in contrast to that of COL1A1, ALP, OPN, and COMP. Smad3 phosphorylation was upregulated by BMP3 and TGF-β, but BMP3 did not affect the phosphorylation of extracellular-signal regulated kinase (ERK) 1/2 or c-Jun N-terminal kinase (JNK). Our results reveal that BMP3 enhances MSC proliferation and differentiation into NP-like cells, as indicated by increased cell numbers and specific gene expressions, and may also cooperate with TGF-β induced positive effects. These actions are likely related to the activation of TGF-β signaling pathway.     

二氢杨梅素防治磨损颗粒诱导的小鼠颅骨骨溶解的实验研究

目的: 探讨二氢杨梅素（DMY）对磨损颗粒诱导的小鼠颅骨骨溶解的作用。方法: 选用30只8周龄雄性C57BL/J6小鼠,随机分成3组,每组10只。分别为假手术组（Sham）、阳性对照组（Control）和二氢杨梅素组（DMY）。假手术组手术不加钛颗粒,阳性对照组和DMY组手术时颅骨部位注入30 mg钛颗粒构建小鼠颅骨骨溶解模型。术后DMY组每天连续予500 mg/kg DMY灌胃;假手术组和阳性对照组给予相应体积的生理盐水灌胃。14 d后取眼眶静脉血,随后处死所有实验动物并收集颅骨标本。所有标本行Micro-CT扫描、采集计算机3D重建图像并进行定量分析,随后标本脱钙后以石蜡包埋,进行病理学分析。 结果: Micro-CT扫描3D重建图像显示DMY组小鼠颅骨表面骨溶解严重程度显著低于阳性对照组;Micro-CT扫描显示DMY组小鼠颅骨骨密度明显高于阳性对照组（P<0.05）。HE染色及TRAP染色分析显示,与阳性对照组相比,DMY组小鼠颅骨骨溶解区域破骨细胞数明显减少。DMY组小鼠血清IL-1β、TNF-α、NF-κB受体激活剂配体（RANKL）水平显著低于阳性对照组（P<0.05）;骨保护素（OPG）水平显著高于阳性对照组（P<0.05）。体外细胞培养实验显示,DMY可在体外显著抑制RANKL诱导的破骨细胞分化。结论: DMY可有效抑制磨损颗粒诱导的小鼠颅骨骨溶解。
