Abstract
Geniposide (GEN), a medical herb, is known for its therapeutic applications in cardiovascular diseases, though its efficacy in treating myocardial ischemia/reperfusion injury (MI/RI) is yet to be fully elucidated. This study is an endeavor to explore the potential protective mechanism of GEN against MI/RI. To simulate the MI/RI condition, the left anterior descending artery was occluded for 30 min, followed by a reperfusion period of 120 min in a rat model. Three dosages (50, 100, or 150 mg/kg) of GEN were intraperitoneally injected to the Sprague-Dawley rats once a day, for seven days before the ligation of the artery. The rats were categorized into sham group, MI/RI group, and three different dosages GEN-treated groups. As the results showed, the pretreatment with GEN mitigated myocardial injury, reduced infarct volume, inhibited apoptosis, enhanced superoxide dismutase activity, and decreased malondialdehyde and myeloperoxidase activity, as well as serum creatine kinase-MB and lactate dehydrogenase levels. Moreover, GEN ameliorated MI/RI by downregulating protein expression of toll-like receptor 4, myeloid differentiation primary response 88, and p-nuclear factor-κB. In conclusion, the pretreatment of GEN may be considered as a potential therapeutic option for MI/RI.

Abstract
The increasing incidence of pregnancy complications, particularly gestational diabetes mellitus (GDM) and preeclampsia (PE), is a cause for concern, as they can result in serious health consequences for both mothers and infants. The pathogenesis of these complications is still not fully understood, although it is known that the pathologic placenta plays a crucial role. Studies have shown that PPARγ, a transcription factor involved in glucose and lipid metabolism, may have a critical role in the etiology of these complications. While PPARγ agonists are FDA-approved drugs for Type 2 Diabetes Mellitus, their safety during pregnancy is not yet established. Nevertheless, there is growing evidence for the therapeutic potential of PPARγ in the treatment of PE using mouse models and in cell cultures. This review aims to summarize the current understanding of the mechanism of PPARγ in placental pathophysiology and to explore the possibility of using PPARγ ligands as a treatment option for pregnancy complications. Overall, this topic is of great significance for improving maternal and fetal health outcomes and warrants further investigation.

Abstract
OBJECTIVE Inflammation and oxidation brought on by myocardial ischemia-reperfusion (MI/R) injury lead to cardiomyocyte apoptosis and necrosis. The receptor interacting serine/threonine kinase 2 (RIPK2) plays significant roles in oxidative stress and excessive inflammation. The purpose of this research is to examine the roles of RIPK2 in MI/R injury. METHODS The in vivo animal model was constructed by acute coronary I/R, and the in vitro cell model was established by oxygen and glucose deprivation/reperfusion (OGD/R)-stimulated cardiomyocyte injury. RIPK2 expression was examined using qRT-PCR and Western blot. CCK-8 was proposed as a method for detecting cell proliferation. ELISA was utilized to measure inflammatory cytokines (TNF-α, IL-6, and IL-1β) and myocardial injury indicators (CK-MB, Mb, cTnI, and LDH). The levels of MDA and ROS were determined by the kit and fluorescent probe. H&E was conducted to assess MI/R injury after silencing of RIPK2. RESULTS In MI/R rats and OGD/R-treated H9C2 cardiomyocytes, RIPK2 was overexpressed at both the mRNA and protein levels. RIPK2 inhibition promoted cell proliferation while inhibiting apoptosis, as evidenced by decreased TUNEL-positive cells and cleaved caspase-3. RIPK2 inhibition reduced MDA and ROS levels, as well as the contents of inflammatory factors. RIPK2 silencing reduced CK-MB, Mb, cTnI, and LDH levels in rat serum and alleviated MI/R injury. Furthermore, RIPK2 inhibition increased p-AKT while decreasing NF-B p-p65 expression. CONCLUSION Silencing of RIPK2 reduced apoptosis, proinflammatory factors, and oxidative stress in MI/R by activating AKT and suppressing NF-κB signals, suggesting a potential therapeutic strategy for MI/R injury.

Abstract
Background The various anti-inflammatory, anti-apoptotic, and antioxidant effects of Artesunate (Art) have been explored in numerous studies. This study aimed to evaluate the function of Art on myocardial necrosis in apoptotic cardiomyocytes in vivo and in vitro. Methods Sprague Dawley (SD) rats were randomly divided into groups: a control group, a myocardial ischemia reperfusion (MI/R) group, and MI/R+ Art groups. To establish a MI/R model, rats were subjected to left anterior descending artery ischemia for 45 minutes, and then reperfusion for 2 hours. Hypoxia was induced in H9C2 cells by subjecting them to hypoxic conditions at 37 °C for 4 hours, before placing them in a normoxic chamber for 2 hours. The test methods were used in this test, such as echocardiography, enzyme-linked immunosorbent assay (ELISA), HE staining, TUNEL staining, immunohistochemistry, flow cytometry, western blot, and CCK-8 assay. Results Art improved myocardial systolic function caused by MI/R injury in vivo. Simultaneously, Art reduced the levels of cardiac troponin I (cTnl), creatine kinase-MB (CK-MB) and myohemoglobin (Mb) in vivo and in vitro. Moreover, Art inhibited cardiomyocyte apoptosis in vivo and in vitro. The focal adhesion kinase (FAK)/phosphatidylinositide-3 kinases (PI3K)/AKT signaling pathway was also activated by Art in vivo and in vitro. Furthermore, after inhibitor PF573228 was added, Art inhibited apoptosis in H9C2 cells via activation of the FAK/PI3K/AKT signaling pathway in vitro. Conclusions This study confirms that Art alleviated MI/R injury and inhibited cardiomyocyte apoptosis in vivo and in vitro. Art exerted an inhibitory effect on cardiomyocyte apoptosis by activating the FAK/PI3K/AKT signaling pathway. Therefore, Art may serve as an alternative treatment for MI/R injury.

Abstract
To investigate the effect of hydrogen-rich water on myocardial tissue metabolism in a myocardial ischemia-reperfusion injury (MIRI) rat model. Twelve rats were randomly divided into a hydrogen-rich water group and a control group of size 6 each. After the heart was removed, it was fixed in the Langendorff device, and the heart was perfused with 37 °C perfusion solution pre-balanced with oxygen. The control group was perfused with Kreb's-Ringers (K-R) solution, and the hydrogen-rich water group was perfused with K-R solution + hydrogen-rich water. Liquid Chromatograph Mass Spectrometer (LC-MS) analysis platform was used for metabolomics research. Principle component analysis (PCA), partial least squares discriminant analysis (PLS-DA), orthogonal partial least squares discriminant analysis (OPLS-DA), Variable importance in projection (VIP) value of OPLS-DA model (threshold value ≥1) were employed with independent sample T Test (p < 0.05) to find differentially expressed metabolites, and screen for differential metabolic pathways. VIP (OPLS-DA) analysis was performed with T test, and the metabolites of the control group and the hydrogen-rich water group were significantly different, and the glycerophospholipid metabolism was screened. Seven myocardial ischemia-reperfusion injury (MIRI)-related signaling pathways were identified, including glycerophospholipid metabolism, glycosylphosphatidylinositol (GPI) anchored biosynthesis, and purine metabolism, as well as 10 biomarkers such as phosphatidylcholine, phosphatidylethanolamine and phosphatidylserine. Hydrogen-rich water regulates the metabolic imbalance that could change MIRI myocardial tissue metabolism, and alleviate ischemia-reperfusion injury in isolated hearts of rats through multiple signaling pathways.

Abstract
The aim of this study was to investigate whether lncRNA TUG1 could mediate the progression of ischemia-reperfusion injury following acute myocardial infraction. Mouse cardiomyocytes HL-1 cells were subjected to oxygen glucose deprivation followed by reperfusion (OGD/R) to induce myocardial I/R injury. The expression of TUG1 was detected by real-time PCR. Overexpression or down expression of TUG1 was performed in mouse HL-1 cardiomyocytes. The myocardial cell viability and apoptosis were respectively detected. In addition, the expression levels of inflammatory factors, apoptosis-related proteins and HMGB1 proteins were detected. Besides, an inhibitor of HMGB1 was used to treat cells to verify the relationship between TUG1 and HMGB1 protein. The expression of TUG1 was significantly up-regulated in OGD/R-induced myocardial HL-1 cells. The overexpression of TUG1-induced inflammation and apoptosis in OGD-R-induced myocardial HL-1 cells. Knock down of TUG1 protected OGD/R-induced myocardial I/R injury by inhibiting HMGB1 expression. Suppression of lncRNA TUG1 may prevent myocardial I/R injury following acute myocardial infarction via inhibiting HMGB1 expression.
