Study on the Antidepressant Effect of Zhizichi Decoction by Regulating Metabolism and Intestinal Flora.

Background: The incidence of depression is increasing year by year, and Zhizichi Decoction（ZZCD）has shown significant efficiency in the clinical treatment of mild depression, but its mechanism of action is still unclear. In this research, network pharmacology and metagenomics combined and metabolomics were used as research methods to explain the scientific connotation of the antidepressant effect of ZZCD from the aspects of the overall effect of organisms and microbial structure and function.

Methods: The rat model of depression was established by chronic unpredictable mild stress (CUMS), and the improvement of depressive symptoms was evaluated by behavioral and histopathological methods.

Detection and Characterization of the Metabolites of Ciwujianoside B in Rats Based on UPLC-Fusion Lumos Orbitrap Mass Spectrometry.

We previously conducted a systematic study on the metabolic process and products of hederasaponin B in rats. We hypothesized that the sugar chain structures play a key role in the metabolism of triterpenoid saponins. To verify this hypothesis, we conducted metabolic research on ciwujianoside B ascribed to the same sugar chains and a distinct aglycone and compared it with hederasaponin B.

A metabolism-based study of the mechanism of action of Scrophularia ningpoensis Hemsl. on nephrogenic edema.

Nephrogenic edema (NE) is a type of edema with hypoproteinemia and water and sodium retention as a result of renal injury. Traditional Chinese medicine has proved that Scrophularia ningpoensis Hemsl. has an effect on NE, but its mechanism is not clear.

[Mechanism of Huanglian Wendan Decoction in improving impaired glucose tolerance based on skeletal muscle NLRP3/caspase-1/IL-1β, IL-18 pathway].

This study investigated the mechanism of improving impaired glucose tolerance(IGT) of rats by Huanglian Wendan Decoction from the perspective of the skeletal muscle Nod-like receptor protein 3(NLRP3)/cysteinyl aspartate specific proteinase-1(caspase-1)/interleukin-1β(IL-1β), interleukin-18(IL-18) pathway. Healthy male SD rats were fed with the diet containing 45% fat for 20 weeks, accompanied by a high-temperature and high-humidity environment and an inactive lifestyle, for the establishment of the IGT rat model. The rats were divided into the blank control group, model control group, metformin hydrochloride group(positive drug group, 0.

[Effects of Scrophulariae Radix and Split Component on Isoproterenol-Induced Ventricular Remodeling in Rat].

Objective: To explore the effects and mechanism of Scrophulariae Radix and split component on experimental ventricular remodeling.

Methods: The rats were injected subcutaneously by 10,5 mg / kg ISO for 2 d and then 3 mg / kg ISO as maintenance dose for 7 d to build the the ventricular remodeling. After 21 days’ treatment,the left ventricular mass index( LVMI) and heart mass index( HMI) were measured.

[Progress in the molecular genetic mechanism of gonadoblastoma].

Gonadoblastoma (GB), a rare in situ germ cell tumor derived from sex cord and germ cells, is closely associated with gonadal dysgenesis. About 80% of GB individuals exhibit 46, XY female phenotype while the others are 45, XY and 46, XX with disorders of sex development. Moreover, 35% of GB can eventually develop into malignant tumors, such as seminoma and dysgerminoma tumors.
