目的基于托法原则研究探索姜黄素靶向内核苷酸结合寡聚化结构域样受体家族含热蛋白结构域蛋白3(nucleotidebinding domain and leucine-rich repeat protein 3,NLRP3)/炎症小体炎症因子白细胞介素1β(recombinant human interleukin-1β...目的基于托法原则研究探索姜黄素靶向内核苷酸结合寡聚化结构域样受体家族含热蛋白结构域蛋白3(nucleotidebinding domain and leucine-rich repeat protein 3,NLRP3)/炎症小体炎症因子白细胞介素1β(recombinant human interleukin-1β,IL-1β)炎性通路对巨大肩袖撕裂中肌肉脂肪浸润的抑制作用及机制。方法构建30只大鼠肩关节慢性巨大肩袖撕裂模型,并根据姜黄素给入的剂量不同将30只大鼠模型分为3组,即普通膳食组、姜黄素混合膳食低剂量组、姜黄素混合膳食高剂量组,每组各有大鼠模型10只。对30只大鼠肩关节慢性巨大肩袖撕裂模型分别进行药物干预后,获取3组大鼠模型在第2、3、4周的肩关节固定脱钙组织切片,分别检测3组大鼠模型的脂肪浸软程度,并对大鼠巨大肩袖撕裂肌肉组织中NLRP3、IL-1β指标进行检测,探讨姜黄素对巨大肩袖撕裂中肌肉脂肪浸润的抑制作用。结果相比于普通膳食组,姜黄素混合膳食低剂量组和高剂量组的炎症因子水平均明显下降,且姜黄素混合膳食高剂量组下降的具有明显的特征性,差异有统计学意义(P<0.05)。结论根据托法理论的治疗原则,利用姜黄素治疗巨大肩袖撕裂能够有效地干预该疾病的脂肪浸润,这主要是由于姜黄素治疗能够通过对NLRP3炎症小体进行有效地抑制,减少IL-1β的生成,从而能够有效地减轻骨骼肌炎性损伤,能够通过NLRP3/IL-1β炎性通路抑制骨骼肌干细胞的脂肪分化,减少慢性过程中肌肉的脂肪浸润,从而改善肩袖肌腱肌肉的生物活力。展开更多

However, few studies have been conducted among males, perhaps due to the rarity with which they maintain friendly relationships with one another and their aggressive competition for resources. Although this is true for many primate males, Sichuan snub-nosed monkeys Rhinopithecus roxellana represent a potential exception as male cooperation has been known to occur. In this study, using postconfiict/ matched-control（PC-MC） and time-rule methods, we analyzed postconflict behavior among males and the possible occurrence of bystander affiliation or reconciliation. A total of 246 PC-MC pairs among leader males were obtained. On average, each leader male exhibited only 0.04 aggressive be- haviors per observation hour, and conciliation among leader males occurred at a low rate （2.03%） relative to other primate species. The occurrence of consolation-affiliation interactions between focal males and group members other than former opponents differed significantly between PCs and MCs, which is the first time this has been confirmed among R. roxellana males. We discuss the results in light of recent theories concerning consolation in primates. The patterns of postconflict contact demonstrated that R. roxellana may be a unique species among colobines.展开更多
