简介：摘要：目的 通过建立骨关节炎模型探讨整合素pI和GIT 1对软骨细胞的影响，及二者之间的调控关系。对临床上骨性关节炎的治疗起指导作用。 方法 采用约一周龄的年乳大鼠20只，用定量PCR和Western Blotting检测对照组、pcDNA3.1空载体转染组、pcDNA3.1-GIT 1过表达组、pcDNA3 . I -integrin-p1过表达组、integrin-p 1 siRNA组和NC siRNA组中，integrin-p1和GIT1的mRNA和蛋白质的表达水平，来判断integrin-p1和GIT1之间的调控关系。结论 integrin-p1可以调控GIT1的表达，GTI1可能是位于integrin-pI下游的一个关键分子。

简介：【摘 要】目的：观察5.5号头皮针在慢性病病人静脉输液中的临床效果。方法：选取2019年6月至2020年8月我院收治的100例慢性病病人作为实验样本，参照红蓝球法分为对照组（n=50）和研究组（n=50）。对照组选择7号头皮针输液，研究组选择5.5号头皮针输液，对比两组临床效果的不同。结果：研究组比对照组的一次穿刺成功率高，比其血管反应发生率、VAS评分低，两组差异明显，具有统计学意义（P＜0.05）。结论：慢性病病人采用5.5号头皮针进行静脉输液，有利于进一步提高穿刺成功率，缓解疼痛感，保护血管，值得借鉴和采纳。
