The mechanism of the preventive effect of Shen'an capsule on the calcium oxalate crystal-induced early renal injury based on metabolomics.

Kidney stone disease is a worldwide metabolism-associated disorder with a high incidence of renal dysfunction. However, effective methods to prevent crystalline nephropathy are still lacking owing to the absence of aetiological research. Shen'an (SA) capsules are prepared from Chinese medicinal compounds and are considered a promising treatment for the prevention of crystal-induced renal injury. In this study, 24 mice were randomly divided into four groups: saline, oxalate, SA-treated (via preventive administration) and SA-only groups. A metabolomics analysis based on ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) was performed to explore the plasma metabolic profiles among the different groups. The amount of crystal deposition and the decline in kidney function were significantly alleviated by the use of SA capsule. A total of 24 metabolites that showed a reversal trend following SA capsule administration were identified as plasma biomarkerss of the preventive effects of SA capsules on crystal-induced renal injury. Most of these metabolites were involved in the metabolisms of lipid metabolism, energy metabolism, glutathione metabolism and vitamin metabolism. In conclusion, SA capsules exert a preventive effect in mice with crystal-induced kidney injury via the regulation of multiple metabolic pathways.

The prognostic effect of LINC00152 for cancer: a meta-analysis.

No meta-analysis has been performed to evaluate the association between LINC00152 and the survival of patients with cancers. We thus carried out this study. The online databases, such as PubMed, EMBASE, and the Cochrane controlled trials register, were searched to identify relevant articles. Dichotomous data were analyzed using the odds ratio (OR) as the summary statistic. The association between LINC00152 and survival of cancer was analyzed by pooling the hazard ratio (HR) with its corresponding 95% confidence interval (CI). Nine studies with 862 patients with cancer were included in this meta-analysis. The expression of LINC00152 was not associated with the age of patients (OR = 0.79, 95% CI = 0.55-1.14) and gender (OR = 1.08, 95% CI = 0.74-1.58). However, we found significant positive associations between LINC00152 and lymph node metastasis (OR = 2.54, 95% CI = 1.54-4.18) and TNM stage (OR = 2.32, 95% CI = 1.36-3.93). Furthermore, the expression of LINC00152 was significantly associated with tumor recurrence (OR = 3.32, 95% CI = 1.98-5.57) and shorter OS (HR = 1.94, 95% CI = 1.25-3.02). In conclusion, the results of this meta-analysis suggest that LINC00152 might be a biomarker for shorter OS and tumor recurrence in cancers.
