目的观察胰高血糖素样肽1(GLP-1)受体激动剂利拉鲁肽皮下注射对肥胖雄性小鼠血清性激素水平的影响。方法取雄性C57BL/6J小鼠18只,随机分为正常组、模型组、干预组,每组各6只。正常组给予普通饲料喂养,模型组和干预组通过给予高脂饲料喂养建立肥胖模型;饲养10周后造模成功,干预组皮下注射利拉鲁肽100μg/(kg·d),正常组和模型组给予等体积生理盐水皮下注射,连续12周。每周测量小鼠体质量;给药结束后使用血糖试纸测量空腹血糖(FBG),ELISA法检测血清胰岛素(INS)、黄体生成素(LH)、促卵泡激素(FSH)、睾酮(T)、游离睾酮(FT)、雌二醇(E2)和性激素结合球蛋白(SHBG),计算胰岛素抵抗指数(HOMA-IR)。结果与正常组比较,模型组0、4、8、12周时体质量均升高(P均0.05)。给药结束后,与正常组比较,模型组血清FBG、INS、HOMA-IR升高(P均<0.01);与模型组比较,干预组血清FBG、INS、HOMA-IR降低(P均<0.01)。与正常组比较,模型组血清LH、FSH、T、FT水平降低,E2、SHBG水平升高(P均<0.05);与模型组比较,干预组血清LH、FSH、T和FT水平升高,E2和SHBG水平降低(P均<0.05)。结论肥胖雄性小鼠的性激素水平存在异常;利拉鲁肽能够改善肥胖雄性小鼠的性激素水平,其机制可能与其显著降糖及减轻体质量的作用有关。

OBJECTIVE:To observe the effects of electroacupuncture at Neiguan(PC6)at different time points on reperfusion arrhythmia(RA)after myocardial ischemia and reperfusion in rats,and to investigate the correlation of this protective effect with nerve growth factor(NGF),tyrosine kinase A(Trk A),tyrosine hydroxylase(TH),and norepinephrine(NE).METHODS:A total of 72 Sprague-Dawley male rats were randomly divided into six groups(n=12 rats/group):normal group(Norm),sham operation group(Sham),ischemia reperfusion group(I/R),pre-ischemic electroacupuncture group(EAI),pre-reperfusion electroacupuncture group(EAII),post-reperfusion electroacupuncture group(EAIII).The myocardial ischemia-reperfusion injury(MIRI)model was induced by occlusion of left anterior descending coronary artery for 20 min followed by reperfusion for 40 min in *** no intervention in the Norm group and only threading without ligation in the Sham *** pretreatment at 20 min/d for 7 d before ligation in the EAⅠgroup,20 min of electroacupuncture before reperfusion in the EAII group and 20 min of electroacupuncture after reperfusion in the EAIII *** electrocardiogram(ECG)of each group was recorded throughout the whole process,and the success of the MIRI model was determined based on the changs of J-point and T-wave in the *** arrhythmia score was used to record premature ventricular contractions,ventricular tachycardia and ventricular fibrillation during the reperfusion period to assess the reperfusion induced *** expression levels of NGF,Trk A,TH protein were measured by Western ***,the expression levels of plasma and myocardial NE levels were detected by enzyme linked immunosorbent ***:The differences between Norm group and Sham group were not statistically significant in all *** score,myocardial NGF,Trk A,TH,and NE expression were significantly higher in the I/R group compared with the Sham *** score,myocardial NGF,T

胃肠间质瘤(GIST)是胃肠道最常见的间叶源性肿瘤。随着对GIST诊疗的进步,患者生存期显著延长,疾病进入“慢性病”范畴。因此,如何对患者进行有效的全程化信息化管理是每一位GIST同仁面临的重要问题。我们认为:每一位GIST患者都有进行全程化管理的需求,这也是保障患者疗效的重要因素;信息化管理的理念、符合GIST疾病特点的管理系统以及专职的GIST疾病管理员,是实现全程化管理的保障,也是实现GIST诊治同质化的必备条件。
