对TC18钛合金进行不同工艺的单相区热处理(温度为T_(β)+(15~35)℃,时间为0.5、1、2、4 h),获得不同晶粒尺寸的初始组织,探究晶粒尺寸对双重退火TC18钛合金棒材性能的影响,得到其组织-服役性能一致性的热处理工艺。结果表明,随平均晶粒尺寸增大,TC18钛合金的抗拉强度先升高后降低,而断后伸长率、断面收缩率和断裂韧度则呈相反趋势。为使TC18钛合金构件既具有较高的抗拉强度,又具有良好的塑性和韧性,晶粒尺寸需控制在300~430μm范围,对应的单相区温度和保温时间分别为T_β+(25~35)℃和2~4 h。

背景:大麻二酚能够有效改善机体的炎症反应,但在改善力竭运动引起的骨骼肌炎症方面,并未有明确的机制研究。目的:利用转录组学测序技术探究大麻二酚在力竭运动过程中对大鼠骨骼肌炎症的影响机制。方法:随机将36只SD大鼠分为6组:空白对照组、运动椰子油组、运动对照组、50 mg/kg大麻二酚组、60 mg/kg大麻二酚组、70 mg/kg大麻二酚组,每组6只。除空白对照组大鼠外,其余各组大鼠进行为期9 d的游泳运动制作力竭运动模型。每次游泳运动结束后,大麻二酚组大鼠给予不同浓度(50,60,70 mg/kg)脂溶性大麻二酚2 mL灌胃;运动椰子油组大鼠给予同等体积椰子油灌胃,直至第9天运动结束;空白对照组和运动对照组大鼠不做特殊处理。使用ELISA及转录组测序技术测定不同组大鼠骨骼肌中炎症因子的水平及差异基因,将得到的差异基因进行KEGG分析,并通过荧光定量PCR验证测序数据的准确性。结果与结论:(1)ELISA检测结果显示,相比于空白对照组和运动椰子油组,运动对照组中白细胞介素6(P<0.05)、肿瘤坏死因子α(P<0.01)、白细胞介素10等质量浓度均增加;经大麻二酚干预后,白细胞介素6、肿瘤坏死因子α质量浓度随大麻二酚浓度的加大而呈现依次递减的趋势;(2)通过GO和KEGG数据库的比较,对差异基因的功能特性进行分析,结果表明差异基因主要参与肿瘤坏死因子信号通路和Toll样受体信号通路;(3)RT-qPCR验证结果显示,随机选择5个差异基因的变化趋势与转录组测序结果相一致。结论:大麻二酚能够改善力竭运动引起的骨骼肌炎症反应。

To investigate the effects of recombinant human adiponectin on the metabolism of diabeticswine induced by feeding a high-fat/high-sucrose diet (HFSD),diabetic animal models were constructedby feeding swine with HFSD for 6 *** effects of recombinant adiponectin were assessed bydetecting the change of plasma glucose levels by commercially available enzymatic method test kits andevaluating the insulin sensitivity by oral glucose tolerance test (OGTT). About 1.5 g purified recombinantadiponectin was produced using a 15-liter fermenter.A single injection of purified recombinant humanadiponectin to diabetic swine led to a 2- to 3-fold elevation in circulating adiponectin,which triggered atransient decrease in basal glucose level (P<0.05).This effect on glucose was not associated with anincrease in insulin ***,after adiponectin injection,swine also showed improved insulin sensitivitycompared with the control (P<0.05).Adiponectin might have the potential to be a glucose-lowering agentfor metabolic *** as a potent insulin enhancer linking adipose tissue and glucose metabolismcould be useful to treat insulin resistance.
