Geraniin, a polyphenol derived from the fruit peel of Nephelium lappaceum L., has been shown to possess anti-inflammatory and antioxidant properties in the cardiovascular system. The present study explored whether geraniin could protect against an isoproterenol (ISO)-induced cardiac hypertrophy model. Mice in the ISO group received an intraperitoneal injection of ISO (5 mg/kg) once daily for 9 days, and the administration group were injected with ISO after 5 days of treatment with geraniin or spironolactone. Potential therapeutic effects and related mechanisms analysed by anatomical coefficients, histopathology, blood biochemical indices, reverse transcription-PCR and immunoblotting. Geraniin decreased the cardiac pathologic remodeling and myocardial fibrosis induced by ISO, as evidenced by the modifications to anatomical coefficients, as well as the reduction in collagen I/III á1mRNA and protein expression and cross-sectional area in hypertrophic cardiac tissue. In addition, geraniin treatment reduced ISO-induced increase in the mRNA and protein expression levels of interleukin (IL)-6, IL-1β and tumor necrosis factor-α, whereas ISO-induced IL-10 showed the opposite behaviour in hypertrophic cardiac tissue.Further analysis showed that geraniin partially reversed the ISO-induced increase in malondialdehyde and nitric oxide, and the ISO-induced decrease in glutathione, superoxide dismutase and glutathione. Furthermore, it suppressed the ISO-induced cellular apoptosis of hypertrophic cardiac tissue, as evidenced by the decrease in Bcell lymphoma-2 (Bcl-2)-associated X/caspase-3/caspase-9 expression, increase in Bcl-2 expression, and decrease in TdT-mediated dUTP nick-end labeling-positive cells.These findings suggest that geraniin can attenuate ISO-induced cardiac hypertrophy by inhibiting inflammation, oxidative stress and cellular apoptosis.

Objective: To investigate the effects of paeoniflorin (Pae) on acute kidney injury ( AKI) and mouse renal tubular epithelial cell ( mRTEC) damage induced by lansoprazole (LPZ) and cisplatin (CIS) through in vivo and in vitro experiments . Methods : The C57BL/6J mice or mRTECs were divided into four groups : normal control (NC) group , NC + LPZ group , CIS group , and CIS + LPZ group . Serum creatinine (CRE) and blood urea nitro- gen (BUN) levels in mice were measured , and kidney pathology was observed with HE staining. Western blot , im- munohistochemistry , and immunofluorescence were used to detect the expression levels of kidney injury molecule-1 (KIM-1) and receptor-interacting protein kinase (RIPK) 1 , RIPK3 , and mixed lineage kinase domain-like protein (MLKL) . Subsequently , C57BL/6J mice or mRTECs were divided into six groups : NC group , NC + Pae group , CIS + LPZ (M) group , and CIS + LPZ + Pae ( M + Pae) group . Serum CRE and BUN levels in each group were measured , kidney pathology was observed with HE staining , and ultrastructural changes in the kidney were observed with transmission electron microscopy. The KIM-1 and necroptosis-related protein expression levels were detected by Western blot , immunohistochemistry , and immunofluorescence . Results: Compared with the NC group , CRE and BUN levels were elevated in the CIS group , and these levels were further increased after LPZ in- tervention (all P < 0. 001) . Compared with the CIS group , renal tubular dilation and brush border loss were evi- dent in the CIS + LPZ group based on HE staining of kidney tissue (P < 0. 001) . Compared with the NC group , the expression levels of KIM-1 , RIPK1 , RIPK3 , and MLKL in the renal tissues of mice in the CIS group increased ( all P < 0. 001) , and compared with the CIS group , The expression levels of KIM-1 , RIPK1 , RIPK3 and MLKL in the renal tissues of mice in the CIS + LPZ group increased (all P < 0. 001) . After Pae treatment , compared with group M , the expression levels of CRE , BUN , KIM-1 , RIPK1 , RIPK3 and MLKL in each group of mice decreased significantly and in a dose-dependent manner (all P < 0. 001) . Conclusion LPZ promotes CIS-induced AKI by enhancing necroptosis in renal tubular epithelial cells , and Pae can improve CIS and LPZ-induced AKI by inhibi- ting necroptosis .

Objective: To understand the prevalence and its influencing factors of metabolic syndrome (MS) among employees in petrochemical enterprises, so as to provide insights into the prevention and control of MS among employees in petrochemical enterprises. Methods: The employees in petrochemical enterprises who underwent health examinations at the Fourth Affiliated Hospital of Gansu University of Traditional Chinese Medicine from May 2021 to December 2022 were selected as the survey subjects. Demographic information, lifestyle behaviors and occupational exposure were collected using questionnaires, and the blood biochemical indicators were measured through laboratory testing. Factors affecting MS were identified using a multivariable logistic regression model. Results: A total of 2 479 individuals were included, with a mean age of (44.84±7.87) years. There were 1 684 males (67.93%) and 795 females (32.07%). There were 905 cases of MS, with a detection rate of 36.51%. Multivariable logistic regression analysis showed that gender (male, OR=2.246, 95%CI: 1.353-3.728), age (≥40 years, OR=3.523, 95%CI: 2.003-6.194), noise exposure (OR=1.894, 95%CI: 1.272-2.821), smoking index (>0~200 cigarette-years, OR=1.907, 95%CI: 1.155-3.149; >200 cigarette-years, OR=2.257, 95%CI: 1.320-3.859), hyperuricemia (OR=3.013, 95%CI: 1.852-4.900) and γ-glutamyltransferase (abnormal, OR=2.691, 95%CI: 1.589-4.559) were the influencing factors of MS among employees in petrochemical enterprises. Conclusion The risk of MS occurrence among employees in petrochemical enterprises is related to gender, age, noise exposure, smoking index, hyperuricemia and γ-glutamyltransferase level.

Objective:To compare the diagnostic performance of multiparametric magnetic resonance imaging (mpMRI) and prostate-specific membrane antigen (PSMA) PET/CT in detecting pelvic lymph node metastasis in prostate cancer.Methods:This is a retrospective case series study. A retrospective analysis was conducted on the data of 115 prostate cancer patients who underwent both mpMRI and PSMA PET/CT before undergoing radical prostatectomy and extended pelvic lymph node dissection at the Department of Urology, Xiangya Hospital, Central South University, between March 2020 and September 2023. The age ( M(IQR)) was 67(10) years (range: 45 to 84 years), and the body mass index was 24(4) kg/m 2 (range: 18 to 30 kg/m 2). Pathological and imaging data were obtained from the patients. Lymph node pathology results were used as the gold standard to evaluate the diagnostic performance of mpMRI and PSMA PET/CT for detecting pelvic lymph node metastasis in PCa through diagnostic evaluation tests. Comparisons between groups were performed using independent samples t-test, Mann-Whitney U test, or χ2 test. Results:The positive rate for detecting pelvic lymph node metastasis was 18.3% (21/115) with mpMRI and 25.2% (29/115) with PSMA PET/CT. The pathological positive rate for lymph nodes was 28.7% (33/115). In patient-based analysis, the diagnostic sensitivity of PSMA PET/CT was significantly higher than that of mpMRI (63.6% vs. 30.3%, χ2=7.36, P=0.007). In lesion-based analysis, both the sensitivity and positive predictive value of PSMA PET/CT were significantly higher than those of mpMRI (sensitivity: 68.0% vs. 21.6%, χ2=42.20, P<0.01; positive predictive value: 50.0% vs. 23.1%, χ2=7.54, P=0.006). Conclusions:PSMA PET/CT and mpMRI both demonstrates good specificity in predicting pelvic lymph node metastasis in prostate cancer. However, PSMA PET/CT is significantly superior to mpMRI in terms of sensitivity and the detection rate of pathologically positive lymph nodes.
