RESUMEN
Background: The highly heterogeneous pathogenesis of depression and limited response to current antidepressants call for more objective evidence for depression subtypes. Reactive and endogenous depression are two etiologically distinct subtypes associated with different treatment responses. This study aims to explore the potential biomarkers that differentiate reactive and endogenous depressions. Methods: The clinical manifestations and biological indicators of 64 unmedicated mild-to-moderate depression patients (32 reactive depression patients and 32 endogenous depression patients) and 21 healthy subjects were observed. The 24-item Hamilton rating scale for depression (HAMD-24) was used to evaluate the severity of depression. Serum levels of depression-related biological indicators were measured by using the enzyme-linked immunosorbent assay. Results: The NLRP3 level of reactive depression was significantly lower than those of endogenous depression and healthy controls. There was a significant negative correlation between the BDNF level and the HAMD-24 total scores for patients with reactive depression. Conclusion: Our findings suggested the serum NLRP3 and BDNF levels could be potential biomarkers for detecting and evaluating the severity of reactive depression.
RESUMEN
Lotus leaf (LL) is one of the traditional Chinese herbs which can be used for both pharmaceutical and food application, and it posses lipid regulating efficacy. To observe the effect of LL on experimental nonalcoholic fatty liver disease (NAFLD) and its potential mechanism, a NAFLD model was established by feeding SD rat with high-fat and high-glucose diet. LL was administrated to rats in experiment group at the same time. AST,ALT,Cr,BUN,GLU levels in serum were determined by automatic biochemical analyser and TNF-α,IL-6,INS,ADPN,LEP and liver NF-κB,TGF-ß1 levels were determined by ELISA according to the specification of the kits. HE staining was applied for histopathological examination and RT-PCR,Western blot was applied for AdipoR2 mRNA and protein expressionï¼Results have shown that LL could significantly decrease ALT,AST,IL-6 level in serum and NF-κB,TGF-ß1 level in liver,promote adiponectin content in serum and AdipoR2 protein expression in liver and could alleviate hepatocyte lipid degeneration. These results indicating that LL has protective effect for NAFLD induced by high-fat and high-glucose diet via promoting AdipoR2 expression, improving insulin resistance and inhibiting inflammatory reaction.
