Abstract
Diabetes mellitus (DM) and cardiovascular complications are two unmet medical emergencies that can occur together. The rising incidence of heart failure in diabetic populations, in addition to apparent coronary heart disease, ischemia, and hypertension-related complications, has created a more challenging situation. Diabetes, as a predominant cardio-renal metabolic syndrome, is related to severe vascular risk factors, and it underlies various complex pathophysiological pathways at the metabolic and molecular level that progress and converge toward the development of diabetic cardiomyopathy (DCM). DCM involves several downstream cascades that cause structural and functional alterations of the diabetic heart, such as diastolic dysfunction progressing into systolic dysfunction, cardiomyocyte hypertrophy, myocardial fibrosis, and subsequent heart failure over time. The effects of glucagon-like peptide-1 (GLP-1) analogues and sodium-glucose cotransporter-2 (SGLT-2) inhibitors on cardiovascular (CV) outcomes in diabetes have shown promising results, including improved contractile bioenergetics and significant cardiovascular benefits. The purpose of this article is to highlight the various pathophysiological, metabolic, and molecular pathways that contribute to the development of DCM and its significant effects on cardiac morphology and functioning. Additionally, this article will discuss the potential therapies that may be available in the future.

Abstract
BACKGROUND Diabetic cardiomyopathy, secondary to diabetes, is the main cause of death in patients with diabetes. In China, traditional Chinese medicine has achieved good performance in treating diabetic cardiomyopathy. However, to date, no systematic review or meta-analysis has been published on the treatment of diabetic cardiomyopathy by traditional Chinese medicine. METHODS This study strictly followed the preferred guidelines for systematic review. Two researchers searched seven databases: EMbase, PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journal Database, and WANFANG Database. The retrieval time limit ranged from the establishment of the database to August 2022. All clinical randomized controlled trials that met the inclusion and exclusion criteria were included in this study. Statistical analysis was performed using RevMan 5.3. RESULTS This study analyzed the clinical efficacy and safety of traditional Chinese medicine in the treatment of diabetic cardiomyopathy. CONCLUSION The results of this study provide evidence-based medical evidence for the clinical use of traditional Chinese medicine in the treatment of diabetic heart disease in the future.

Abstract
OBJECTIVE To investigate the regulation of adiponectin/miR-711 on TLR4/NF-κB-mediated inflammatory response and diabetic cardiomyocyte apoptosis. METHODS Diabetes models were established using rats and H9c2 cardiomyocytes. qRT-PCR was used to detect adiponectin, miR-711, and TLR4. MTT, β-galactosidase staining, and flow cytometry were utilized to assess cell viability, senescence, and apoptosis, respectively. The colorimetric method was used to measure caspase-3 activity, DCFH-DA probes to detect ROS, and western blotting to determine the protein levels of Bax, Bcl-2, TLR4, and p-NF-κB p65. ELISA was performed to measure the levels of adiponectin, ICAM-1, MCP-1, and IL-1β. Dual-luciferase reporter system examined the targeting relationship between miR-711 and TLR4. H&E and TUNEL staining revealed myocardial structure and apoptosis, respectively. RESULTS Adiponectin and miR-711 were underexpressed and TLR4/NF-κB signaling pathway was activated in high glucose-treated H9c2 cells. High glucose treatment reduced viability, provoked inflammatory response, and accelerated senescence and apoptosis in H9c2 cells. miR-711 could bind TLR4 mRNA and inactivate TLR4/NF-κB signaling. Adiponectin treatment increased miR-711 expression and blocked TLR4/NF-κB signaling. Adiponectin/miR-711 reduced myocardial inflammation and apoptosis in diabetic rats. CONCLUSION Adiponectin inhibits inflammation and alleviates high glucose-induced cardiomyocyte apoptosis by blocking TLR4/NF-κB signaling pathway through miR-711.

Abstract
Diabetes mellitus is a common disease affecting millions of people worldwide. This disease is not limited to metabolic disorders but also affects several vital organs in the body and can lead to major complications. People with diabetes mellitus are subjected to cardiovascular complications, such as cardiac myopathy, which can further result in major complications such as diabetes-induced cardiac failure. The mechanism underlying diabetes-induced cardiac failure requires further research; however, several contributing factors have been identified to function in tandem, such as reactive oxygen species production, inflammation, formation of advanced glycation end-products, altered substrate utilisation by mitochondria, activation of the renin-angiotensin-aldosterone system and lipotoxicity. Genetic factors such as microRNAs, long noncoding RNAs and circular RNAs, as well as epigenetic processes such as DNA methylation and histone modifications, also contribute to complications. These factors are potential targets for developing effective new therapies. This review article aims to facilitate in depth understanding of these contributing factors and provide insights into the correlation between diabetes mellitus and cardiovascular complications. Some alternative targets with therapeutic potential are discussed to indicate favourable targets for the management of diabetic cardiomyopathy.

Abstract
To clarify the role of TRAF3IP2 in high glucose (HG)-stimulated cardiomyocyte inflammation and apoptosis and its action mechanism. SiRNA plasmid of TRAF3IP2 was constructed and transfected into HG-stimulated cardiomyocytes to silence TRAF3IP2. The expression of TRAF3IP2 was determined by quantitative polymerase chain reaction (qPCR) and western blot. Cell viability and cytotoxicity were first observed using cell counting kit-8 and lactate dehydrogenase assays. The inflammatory injury of the cardiomyocytes was then examined by real time-qPCR (RT-qPCR) and western blot. The oxidative stress of the cardiomyocytes was evaluated using reactive oxygen species assay kit, RT-qPCR, western blot and enzyme activity assay kit. Next, cell apoptosis was detected employing TUNEL and western blot. Finally, RT-qPCR and western blot were performed to investigate the effects of inhibitors of dipeptidyl peptidase-4, including saxagliptin, empagliflozin and linagliptin, on TRAF3IP2. TRAF3IP2 expression was found to be increased in HG-stimulated cardiomyocytes. TRAF3IP2 interference inhibited HG-induced cell viability loss, cytotoxicity, inflammatory response, oxidative stress and apoptosis of the cardiomyocytes. Moreover, saxagliptin, empagliflozin and linagliptin inhibited the expression of TRAF3IP2. TRAF3IP2 interference alleviates HG-induced inflammation and apoptosis of cardiomyocytes. The result suggests that TRAF3IP2 may be a promising therapeutic target in treating diabetic cardiomyopathy.

Abstract
Excessive activation of the renin-angiotensin system (RAS) in diabetic cardiomyopathy (DCM) provokes a series of structural and functional abnormalities, and causes ventricular remodeling and heart failure in diabetes. (Pro)renin receptor (PRR) is a component of the RAS and has been reported to be up-regulated in some cardiovascular diseases. Furthermore, PRR blockade in some cardiovascular diseases, such as myocardial infarction and hypertension, has been demonstrated to reverse their pathogenesis. However, there have been few studies about the function of PRR in the pathogenesis of DCM. In this study, we hypothesized that PRR is involved in the pathogenesis of DCM and mediates myocardial injury in DCM. To explore the role of PRR in DCM, we evaluated the effects of PRR overexpression and knockdown on the DCM phenotype in vivo and in vitro The results show that PRR overexpression exacerbates myocardial injury and the inflammatory response in rats with DCM. Conversely, PRR knockdown alleviates myocardial fibrosis, apoptosis, and the inflammatory response, reversing the cardiac dysfunction in rats with DCM. In cell experiments, PRR overexpression also up-regulated the protein expression of collagen I and fibronectin, aggravated the inflammatory response, and increased the production of reactive oxygen species, whereas PRR knockdown had the opposite effect. Thus, PRR mediates myocardial injury, apoptosis, and the inflammatory response, likely through a PRR/extracellular signal-regulated kinase/reactive oxygen species pathway.

Abstract
Diabetes is a major risk factor for heart disease. Diabetic cardiomyopathy is a long-lasting process that affects the myocardium in patients who have no other cardiac conditions. The condition has a complex physiopathology which can be subdivided into processes that cause diastolic and/or systolic dysfunction. It is believed to be more common than reported, but this has not been confirmed by a large study. Diagnosis can involve imaging; biomarkers cannot be used to identify diabetic cardiomyopathy at an early stage. In people with diabetes, there should be a focus on prevention and, if diabetic cardiomyopathy develops, the objective is to delay disease progression. Further studies into identifying and managing diabetic cardiomyopathy are essential to reduce the risk of heart failure in people with diabetes.

Abstract
Ca2+/calmodulin-dependent protein kinase II (CaMKII) plays an important role in the cardiovascular system. However, the potential protective role of inhibitor 1 of protein phosphatase 1 (I1PP1), which is able to regulate CaMKII, in high glucose-induced cardiomyocytes injury remains unknown. In the present study, cardiomyocytes were transfected with I1PP1 adenovirus to inhibit protein phosphatase 1 (PP1) expression. After the cardiomyocytes were subjected to high glucose stimulation for 48 h, quantitative real-time PCR was used to detect CaMKIIδ alternative splicing. Lactate dehydrogenase (LDH) release and adenosine triphosphate (ATP) level were measured to assess cell damage and energy metabolism respectively. CaMKII activity was represented as phospholamban (PLB) phosphorylation, CaMKII phosphorylation (p-CaMKII) and oxidation (ox-CaMKII). Dihydroethidium (DHE), MitoSOX and JC-1 staining were used to assess oxidative stress and mitochondrial membrane potential. Necroptosis was evaluated by receptor interacting protein kinase 3 (RIPK3) expression, TUNEL and cleaved-caspase 3 levels. RIPK3, mixed lineage kinase domain like protein (MLKL) and dynamin-related protein 1 (DRP1) expressions were also detected. We found that high glucose disordered CaMKIIδ alternative splicing. I1PP1 over-expression suppressed PLB phosphorylation, ox-CaMKII, DRP1, RIPK3 and cleaved-caspase 3 proteins expression, decreased LDH release, attenuated necroptosis, increased ATP level, inhibited oxidative stress, and elevated mitochondrial membrane potential in high glucose-stimulated cardiomyocytes. However, there was no effect on phosphorylation of MLKL (p-MLKL), p-CaMKII, and receptor interacting protein kinase 1 (RIPK1) expression. Altogether, I1PP1 over-expression alleviated CaMKIIδ alternative splicing disorder, suppressed CaMKII oxidation, reduced reactive oxygen species (ROS) accumulation and inhibited necroptosis to attenuate high glucose-induced cardiomyocytes injury.
