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.

ObjectiveTo analyze the distribution characteristics of traditional Chinese medicine (TCM) syndrome elements in different risk populations of heart failure complicated with type 2 diabetes. MethodsClinical data of 675 type 2 diabetes patients were retrospectively collected. Lasso-multivariate Logistic regression was used to construct a clinical prediction nomogram model. Based on this, 441 non-heart failure patients were divided into a low-risk group (325 cases) and a high-risk group (116 cases) according to the median risk score of heart failure complicated with type 2 diabetes. TCM diagnostic information (four diagnostic methods) was collected for both groups, and factor analysis was applied to summarize the distribution of TCM syndrome elements in different risk populations. ResultsLasso-multivariate Logistic regression analysis identified age, disease duration, coronary heart disease, old myocardial infarction, arrhythmia, absolute neutrophil count, activated partial thromboplastin time, and α-hydroxybutyrate dehydrogenase as independent risk factors for heart failure complicated with type 2 diabetes. These were used as final predictive factors to construct the nomogram model. Model validation results showed that the area under the curve (AUC) of the receiver operating characteristic (ROC) curve for the modeling group and validation group were 0.934 and 0.935, respectively. The Hosmer-Lemeshow test (modeling group P = 0.996, validation group P = 0.121) indicated good model discrimination. Decision curve analysis showed that the curves for All and None crossed in the upper right corner, indicating high clinical utility. The low-risk and high-risk groups each obtained 14 common factors. Preliminary analysis revealed that the main disease elements in the low-risk group were qi deficiency (175 cases, 53.85%), dampness (118 cases, 36.31%), and heat (118 cases, 36.31%), with the primary locations in the spleen (125 cases, 38.46%) and lungs (99 cases, 30.46%). In the high-risk group, the main disease elements were yang deficiency (73 cases, 62.93%), blood stasis (68 cases, 58.62%), and heat (49 cases, 42.24%), with the primary locations in the kidney (84 cases, 72.41%) and heart (70 cases, 60.34%). ConclusionThe overall disease characteristics in different risk populations of type 2 diabetes patients with heart failure are a combination of deficiency and excess, with deficiency being predominant. Deficiency and heat are present throughout. The low-risk population mainly shows qi deficiency with dampness and heat, related to the spleen and lungs. The high-risk population shows yang deficiency with blood stasis and heat, related to the kidneys and heart.

Objective:To compare the effectiveness, safety and postoperative recurrence of percutaneous nephrolithotomy (PCNL) with Holmium laser for upper urinary calculi in Uyghur and Han pediatric patients.Methods:The data of 123 Uyghur and 71 Han pediatric patients with upper urinary calculi admitted to First People's Hospital of Kashgar, Xinjiang and Beijing Friendship Hospital, Capital Medical University respectively, from August 2018 to August 2023, were retrospectively reviewed. The gender [males 73 (59.3%) vs.46 (64.8%) ], laterality (single/bilateral: 94/29 vs. 59/12), hydronephrosis [115 (93.5%) vs. 63 (88.7%)] and anatomical abnormalities [2(1.6%) vs. 5(7.0%)] of Uyghur and Han children were not statistically significant ( P>0.05). Uyghur children were older than Han children [5 (3, 7) vs. 3 (2, 6) years old], with a higher proportion of emaciated children [27 (21.9%) vs. 6 (8.5%) cases], a larger maximum stone diameter [(2.30±0.78) vs. (1.96±1.50) cm] and a lower proportion of multiple stones [46 (37.4%) vs. 52 (73.2%) cases] (all P<0.05). All the patients were treated with Holmium laser PCNL. The channels of the procedures in this study include F12-18 small channels and visual puncture channels. The operation datas, stone-free rate (SFR), complication rate (CR) and stone recurrence rate of the two groups were compared. Meanwhile, multiple logistic regression analysis was used to explore the factors influencing these indicators. Results:The operation time for Uyghur children was significantly longer than that of Han children [75.0 (58.0, 93.0) vs. 30.0 (20.0, 48.8) min]. Additionally, a greater proportion of Uyghur children underwent PCNL with F12-18 small channels than Han children [119 (96.7%) vs. 49(69.0%) cases]. The SFR [89.4%(110/123)vs.88.7%(63/71)], and postoperative CR [31.7%(39/123)vs. 26.8%(19/71)] in Uyghur and Han patients were not significantly different (all P>0.05). The recurrence rate in Uyghur children was higher than that observed in Han children [28.1%(25/89) vs. 15.6%(10/64), P=0.033]. The multivariate logistic regression analysis results indicated that the maximum stone diameter was an independent risk factor for SFR in both groups ( OR=0.401, 95% CI 0.191-0.842, P=0.016). Similarly, maximum stone diameter ( OR=1.896, 95% CI 1.088-3.304, P=0.024) and multiple stones ( OR=3.225, 95% CI 1.409-7.384, P=0.024) were identified as independent risk factors for CR. Ethnicity was not independent risk factor for SFR( OR=0.679, 95% CI 0.215-2.140), CR( OR=1.047, 95% CI 0.495-2.215) and stone recurrence rate( OR=0.820, 95% CI 0.285-2.356, all P>0.05). Conclusions:In comparison to Han pediatric patients during the same period, Holmium laser PCNL had similar SFR and CR for treating Uyghur children with upper urinary calculi, who were older, more emaciated and had larger average stone diameters. The higher postoperative recurrence rate of Uyghur children is likely to be associated with higher stone burden. The multivariate logistic regression analysis results showed that ethnicity was not an influential factor in SFR, complication rates, and stone recurrence rates. The findings need to be further validated in larger prospective cohort studies.

There is no effective treatment for castration-resistant prostate cancer that developed from primary prostate cancer. With the deepening research of human gastrointestinal microbiota, it indicated that all kinds of tumors including castration-resistant prostate cancer might be associated with the characteristic changes of gastrointestinal flora, and it might affect the progress of the tumor through multiple ways. The gastrointestinal microbiota of patients could promote the conversion of androgen precursors to active androgens; could participate in the regulation of thymus function and change the immune activity of the body; could provide raw materials such as glutamate and phosphatidylcholine for tumor growth and metabolism. It may also cause local or systemic inflammation in the digestive tract, and then may lead to the occurrence and development of prostate cancer and the formation of castration resistance. This article reviewed the relationship between gut microbiota and the development of castration-resistant prostate cancer from several molecular mechanisms, in order to provide clues for further research in the future.
