ABSTRACT
Objective To explore the mechanism of Jiawei Bazhen Yimu Capsule on premature ovarian failure rats from the perspective of metabolomics.Methods Female SD rats were randomly divided into sham operation group,model group and Jiawei Bazhen Yimu Capsule low,medium and high dose groups,with 10 rats in each group.The model of premature ovarian failure was replicated by removing bilateral ovaries of rats and administered intragastrically once a day for 21 days.The serum samples of rats in each group were analyzed by ultra-high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry(UPLC-Q-TOF-MS).Combined with multivariate statistical analysis,the effects of Jiawei Bazhen Yimu Capsule on differential metabolites in rats with premature ovarian failure were investigated.The differential metabolites identified by MELIN database or KEGG database were imported into Metaboanalyst 5.0 online platform for metabolic pathway analysis.Results A total of 18 potential differential metabolites were screened and identified.Most of the differential metabolites showed a good callback trend after intragastric administration of Jiawei Bazhen Yimu Capsule.These 18 differential metabolites were enriched into 2 metabolic pathways(Pathway Impact>0.1),which were glycerophospholipid metabolism and arachidonic acid metabolism pathways.Conclusion The therapeutic effect of Jiawei Bazhen Yimu Capsule on premature ovarian failure may be related to improving the level of differential metabolites in serum and restoring normal metabolic activities in rats.
ABSTRACT
Objective:To explore the prognostic value of the serum concentration of human soluble stromelysin-2(sST2)combined with ultrasonic left ventricular diastolic function parameters for elderly patients with septic shock.Methods:This prospective study involved 150 elderly patients with septic shock admitted to the intensive care unit(ICU)of the First Hospital of Jiaxing between May 2019 and May 2022.Data on the following parameters were recorded on days 1, 3, 5, and 7 in the ICU: sST2 concentration, mitral early-diastolic inflow peak velocity(E), mitral late-diastolic inflow peak velocity(A), E/A ratio, early diastolic mitral annular velocity(e'), and E/e' ratio.According to the 28-day prognostic outcome obtained during follow-up, patients were divided into a survival group and a death group to compare differences in values of the above parameters between the two groups and at different time points.Logistic regression was used to analyze independent risk factors for 28-day mortality.The receiver operating characteristic(ROC)curve was used to analyze the predictive value for 28-day mortality, and further risk stratification was performed according to optimal cut-off values to compare differences in 28-day mortality under different risk stratification methods.The Kaplan-Meier survival curve was used to compare 28-day cumulative survival under different risk stratification methods and analyze the predictive value of the combination of the parameters for 28-day mortality.Results:On day 5 following ICU admission, e' was lower and E/e' and sST2 were higher in the death group than in the survival group.Univariate and multivariate Logistic regression analysis suggested that sST2(odds ratio: 1.010, P<0.001)was an independent risk factor for 28-day mortality in elderly patients with septic shock.sST2 had a sensitivity of 50.2%, a specificity of 79.1%, and an area under the curve of 0.660 for predicting 28-day mortality in patients with septic shock.The sST2 concentration was 89.3 μg/L on day 5 after ICU admission, which was the clinical cutoff point for predicting 28-day mortality.Based on the risk stratification of sST2 levels, the 28-day mortality rate was higher in the sST2>89.3 μg/L group than in the sST2≤89.3 μg/L group.Kaplan-Meier survival analysis showed that the 28-day cumulative survival rate was significantly lower in the sST2>89.3 μg/L group than in the sST2≤89.3 μg/L group(44.0% vs.66.7%, log-rank test: χ2=9.101, P=0.003).The receiver operating characteristic curve showed that the combination of sST2, e', and E/e' significantly improved the prediction efficiency of 28-day mortality in elderly patients with septic shock, with an area under the curve of 0.844, a sensitivity of 89.7%, and a specificity of 66.5%. Conclusions:sST2 is an independent risk factor for 28-day mortality in elderly patients with septic shock.When combined with e' and E/e', sST2 can more accurately evaluate the survival prognosis of these patients.
ABSTRACT
ObjectiveTo investigate the effect of Jiawei Bazhen Yimu capsule on serum sex hormones， sexual organs and estrogen signaling pathway in female rats with premature ovarian failure. MethodThe key target proteins of Jiawei Bazhen Yimu capsule in the treatment of premature ovarian failure were screened out by network pharmacology analysis. Female healthy SD rats were selected, and the rat model of premature ovarian failure was established by ovariectomy. Fifty ovariectomized rats were randomly divided into a model group, an estradiol (E2) valerate group, and Jiawei Bazhen Yimu capsule low, medium, and high-dose groups. Another 10 healthy female rats were set as a sham operation group. The sham operation group and the model group were given distilled water by gavage, and other administration groups were given corresponding doses of drugs by gavage. After 21 d, the serum hormone levels of female rats were measured, including E2, progesterone (P), follicle stimulating hormone (FSH), and luteinizing hormone (LH). Immunofluorescence staining (IF) was used to detect the protein expression levels of estrogen receptor 1 (ESR1), estrogen metabolism P4503A4 enzyme (CYP3A4), and P45019A1 enzyme (CYP19A1) in the uterine tissues of female rats. ResultAs compared with the model group, the serum E2 and P levels of female rats in the Jiawei Bazhen Yimu capsule low, medium, and high-dose groups were significantly increased. Jiawei Bazhen Yimu capsule improved the endometrial status of female rats and increased positive expression of ESR1, CYP3A4, and CYP19A1 in the uterine tissues of female rats (P<0.05). ConclusionThe mechanism of Jiawei Bazhenyimu capsule in the treatment of premature ovarian failure may be related to its hormone-like effect and activation of the estrogen signaling pathway.
