      目的   探讨神经元型一氧化氮合酶（nNOS）在抑制剂N-硝基-左旋精氨酸甲酯（L-NAME）抑制作用下与新生鼠胃肠道疾病的相关性研究，以进一步研究婴儿肥厚性幽门狭窄（IHPS）等疾病的致病机制。方法   对40只成熟雌性wistar大鼠随机均分4组，怀孕后予怀孕母鼠灌胃，对照组给予生理盐水，低剂量组、中剂量组、高剂量组分别给予L-NAME 60、300、600 mg/（kg·d）L-NAME。新生鼠皮下注射方式，予对照组皮下注射生理盐水，在低剂量组、中剂量组、高剂量组皮下注射L-NAME 25、125、250 mg/（kg·d）L-NAME。统计分析新生鼠幽门中的nNOS表达量、体质量增长情况、胃潴留情况、幽门肌层厚度。结果 （1）低剂量组、中剂量组、高剂量组新生鼠幽门肌层厚度在出生后第1、7、14日龄高于对照组，但组间比较差异无统计学意义（P＞0.05）。（2）与对照组相比，低剂量组、中剂量组、高剂量组的新生鼠出生后第1周体质量增加量更少，胃潴留更明显（P＞0.05）；在出生后的第2周各组体质量增加量差异无统计学意义（P＞0.05）。（3）新生鼠出生后第14天，中剂量组的胃体积大于低剂量组，但低剂量组和对照组之间、中剂量组和高剂量组之间比较差异无统计学意义（P＞0.05）。（4）新生鼠生后第1天，幽门中nNOS的表达被L-NAME以剂量依赖的方式被抑制，随着新生鼠日龄的增长，这种效应逐渐消失。（5）在不同剂量L-NAME的作用下，新生鼠幽门中nNOS表达量、趋势在不同时间点不同。结论 （1）nNOS可以导致新生鼠胃潴留、幽门梗阻，与IHPS相关症状之间存在相关性，但可能不是IHPS病因的唯一分子机制。（2）在新生鼠胃、幽门组织中，nNOS的表达量可以通过负反馈调节机制调节。（3）nNOS表达量上调可能有助于幽门舒张，但可能无法完全逆转IHPS中幽门的进一步肥厚和阻塞。

目的 探讨重楼皂苷Ⅰ（PPI）对慢性髓系白血病细胞（K562）细胞的抑制作用及可能的作用机制。方法 采用CCK-8法筛选药物最适浓度,将培养时间为24 h的药物最适浓度作为后续实验的干预浓度。分组如下：（1）空白组;（2）PPI组;（3）抑制剂组;（4）PPI+抑制剂组。采用CCK-8法检测细胞增殖率;AO/EB染色观察细胞形态;流式细胞术检测凋亡率;ROS检测试剂盒检测活性氧（ROS）含量、还原型谷胱甘肽含量检测试剂盒检测谷胱甘肽（GSH）含量、细胞亚铁比色法测试盒检测细胞亚铁（Fe²⁺）含量;qRT-PCR法和蛋白免疫印迹法检测各组肿瘤蛋白53（p53）、钠氯离子依赖性氨基酸转运蛋白11（SLC7A11）、谷胱甘肽过氧化物酶4（GPX4）mRNA及蛋白表达量。结果 PPI抑制K562细胞的生长,且呈一定的剂量及时间依赖性（与同时间段的对照组0μmol/L比较,均P<0.01）。与空白组相比,PPI抑制K562细胞的增殖,提高了凋亡率,而铁死亡抑制剂（Ferrostian-1）的使用逆转了PPI对K562凋亡的促进作用（P<0.01）。与空白组相比,PPI组ROS、Fe²⁺含量升高,GSH含量下降,而铁死亡抑制剂的使用可下调ROS、Fe²⁺,上调GSH的含量（P<0.01）。PPI组较空白组p53 mRNA和蛋白表达水平升高,而SLC7A11、GPX4 mRNA和蛋白表达水平下降（P<0.05）;PPI+抑制剂组细胞较重楼皂苷组p53 mRNA和蛋白表达水平下降,而SLC7A11、GPX4 mRNA和蛋白表达水平升高（P<0.05）。结论 PPI能够有效抑制K562细胞增殖,促进K562细胞铁死亡,其分子机制可能与p53信号通路的调控有关。

Objective To investigate the inhibitory effect of polyphyllin I（PPI）on chronic myeloid leukemia cells（K562）and its possible mechanism．Methods K562 cell line was cultured in suitable environment,and the optimal concentration of the drug was screened by CCK-8 method．The optimal concentration of the drug cultured for 24 hours was used as the intervention concentration of the follow-up experiment．Cells were divided into the following groups：（1）blank group,（2）saponins group,（3）inhibitor group and（4）saponins + inhibitor group．The cell proliferation rate was detected by CCK-8 method．The cell morphology was observed by AO/EB staining．The apoptosis rate was detected by flow cytometry．The contents of reactive oxygen species（ROS）,glutathione（GSH）and ferrous（Fe²⁺）in different groups were detected,and the expression of mRNA and protein in different groups were detected by qRT- PCR and Western blot respectively．Results PPI significantly inhibited the growth of K562 cells in a dose-and time-dependent manner．Compared with the blank group,PPI significantly inhibited the proliferation of K562 cells and increased the apoptosis rate of K562 cells,while the use of ferroptosis inhibitor（Ferrostian-1）reversed the promoting effect of PPI on apoptosis of K562 cells．Compared with the blank group,the contents of reactive oxygen species（ROS）and ferrous iron（Fe²⁺）increased and the content of glutathione（GSH）decreased in the saponins group．The use of Ferrostian-1 could down-regulate the contents of ROS and Fe²⁺ and increase the content of GSH in the cells treated with the drug．Compared with the blank group,the expression of p53 mRNA and protein in the saponins group increased,while the expression of SLC7A11,GPX4 mRNA and protein decreased．The expression of p53 mRNA and protein in the saponins + inhibitor group was lower than that in the saponins group,while the expression levels of SLC7A11,GPX4 mRNA and protein increased．Conclusions PPI can effectively inhibit the proliferation of K562 cells and promote ferroptosis in K562 cells．The molecular mechanism can be related to the regulation of p53 signal pathway．
