■六维罗比(LWLB)颗粒是治疗糖尿病周围神经病变(DPN)的中药复方。这项研究的目的是研究LWLB颗粒对糖尿病小鼠周围神经病变的影响,并基于非靶向代谢组学方法阐明潜在的机制。
■将一百四十只db/db小鼠随机分为七个组:对照组,DPN组,牡丹(MD)颗粒组,依帕司他(Epa)组,LWLB低,中等,或高剂量(LW-l,LW-m,或LW-h)组。治疗12周后,体重,血糖,机械性痛阈,电机传导速度(MCV),感觉传导速度(SCV),测量小鼠坐骨神经和尾神经的病理组织。使用液相色谱四极杆飞行时间质谱(LC-QTOF-MS)和多变量统计收集血清样品用于非靶向代谢组学分析。通过候选生物标志物的功能富集分析筛选出疾病相关途径。
■LWLB颗粒可改善2型糖尿病小鼠周围神经传导障碍的周围神经病变,主要通过显著提高神经传导速度(P<0.05)和降低机械性痛阈(P<0.05)。总共43种代谢物被鉴定为与LWLB颗粒的治疗效果相关的潜在生物标志物。五十,在LW-1中发现了4和26;23、4和22;以及24、1和16个生物标志物,LW-m,LW-h小组在4号,6th,第12周,分别。五、三,七、五,在MD中发现了四种代谢途径,Epa,LW-l,LW-m,和LW-h组,分别。精氨酸生物合成途径是LW-1中的重叠途径,LW-m,和LW-h组。
■LWLB颗粒对糖尿病周围神经病变有明显的神经保护作用,LWLB对糖尿病db/db小鼠周围神经病变的代谢机制主要与精氨酸生物合成途径有关。
UNASSIGNED: Liu-Wei-Luo-Bi (LWLB) granules was a Chinese compound prescription for treating diabetic peripheral neuropathy (DPN). The aim of this study was to investigate the effect of LWLB granules on diabetic mice with peripheral neuropathy and to elucidate the potential mechanism based on an untargeted metabolomics approach.
UNASSIGNED: One hundred forty db/db mice were randomly divided into seven groups: the Control group, DPN group, Mudan (MD) granules group, Epalrestat (Epa) group, and the LWLB low, medium, or high dose (LW-l, LW-m, or LW-h) group. After 12 weeks of treatment, body weight, blood glucose, mechanical pain threshold, motor conduction velocity (MCV), sensory conduction velocity (SCV), and Pathological Organization of the Sciatic and Caudal Nerves in mice were measured. Serum samples were collected for untargeted metabolomics analysis using liquid chromatography quadrupole time-of-flight mass spectrometry (LC-QTOF-MS) and multivariate statistics. Disease-related pathways were screened out with function enrichment analyses of candidate biomarkers.
UNASSIGNED: LWLB granules can improve the peripheral neuropathy of type 2 diabetic mice with peripheral nerve conduction disorders, mainly through significantly improving the nerve conduction velocity (P < 0.05) and lowering the mechanical pain threshold (P < 0.05). A total of 43 metabolites were identified as potential biomarkers related to the therapeutic effect of LWLB granules. Fifty, 4, and 26; 23, 4, and 22; and 24, 1, and 16 biomarkers were discovered in the LW-l, LW-m, and LW-h groups at the 4th, 6th, and 12th weeks, respectively. Five, three, seven, five, and four metabolic pathways were found in MD, Epa, LW-l, LW-m, and LW-h groups, respectively. The arginine biosynthesis pathway is the overlapping pathway in LW-l, LW-m, and LW-h groups.
UNASSIGNED: LWLB granules have an obvious neuroprotective effect on diabetic peripheral neuropathy, and the metabolism mechanism of LWLB is mainly related to the arginine biosynthesis pathway on diabetic db/db mice with peripheral neuropathy.
