[PMID: 39022264 PMCID: PMC11250336 DOI: 10.21037/qims-23-1407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2023] [Accepted: 05/22/2024] [Indexed: 07/20/2024]
Abstract
Background Epicardial adipose tissue (EAT) is unique type of visceral adipose tissue, sharing the same microcirculation with myocardium. This study aimed to assess the imaging features of EAT in patients with acute myocarditis (AM) and explore the relationships with clinical characteristics. Methods For this retrospective case-control study, totally 38 AM patients and 52 controls were screened retrospectively from January 2019 to December 2022, and the EAT volume was measured from coronary computed tomography (CT) angiography imaging. Histogram analysis was performed to calculate parameters like the mean, standard deviation, interquartile range and percentiles of EAT attenuation. Whether EAT features change was assessed when clinical characteristics including symptoms, T wave abnormalities, pericardial effusion (PE), impairment of systolic function, and the need for intensive care presented. Results The EAT volume (75.2±22.8 mL) and mean EAT attenuation [-75.8±4.4 Hounsfield units (HU)] of the AM group was significantly larger than the control group (64.7±26.0 mL, P=0.049; -77.9±5.0 HU, P=0.044). Among the clinical characteristics, only the presence of PE was associated with changes in EAT features. Patients with PE showed significantly changes in EAT attenuation including mean attenuation [analysis of variance (ANOVA) P=0.001] and quantitative histogram parameters. The mean attenuation of patients with PE (-71.9±4.0 HU) was significantly larger than controls (-77.9±5.0 HU, Bonferroni corrected P<0.001) and patients without PE (-77.4±3.5 HU, Bonferroni corrected P=0.003). Observed in histogram, the overall increase in EAT attenuation could lead to decrease in EAT volume, which resulted in no statistically significant difference in EAT volume between the AM patients with PE and controls (64.7±26.0 vs. 72.2±28.3 mL, Bonferroni corrected P>0.99). Conclusions Compared to controls, EAT volume was significantly larger in AM, and EAT attenuation increased notably in the presence of PE. We recommend evaluating EAT volume and attenuation simultaneously when quantifying EAT using CT attenuation thresholds.

Abstract
The prevalence of obesity and associated chronic diseases continues to increase worldwide, negatively impacting on societies and economies. Whereas the association between excess body weight and increased risk for developing a multitude of diseases is well established, the initiating mechanisms by which weight gain impairs our metabolic health remain surprisingly contested. In order to better address the myriad of disease states associated with obesity, it is essential to understand adipose tissue dysfunction and develop strategies for reinforcing adipocyte health. In this Review we outline the diverse physiological functions and pathological roles of human white adipocytes, examining our current knowledge of why white adipocytes are vital for systemic metabolic control, yet poorly adapted to our current obesogenic environment.

Abstract
Background
Type 2 diabetes mellitus is a major medical condition that constitutes a significant financial burden on most healthcare systems.
Objective
The current research aimed to evaluate the antidiabetic, anti-inflammatory, and antihyperlipidemic effects of 500 mg metformin twice daily for 6 months on various adipocytokines in type 2 diabetes mellitus patients.
Patients and methods
The participants in this study were divided into three groups: the control, the untreated diabetic, and the metformin-treated diabetic groups.
Results and conclusion
Metformin treatment significantly improved the poor oral glucose tolerance and the lowered serum levels of insulin and C-peptide with subsequent better homeostatic model assessment for insulin resistance and sensitivity and β-cell function results. Moreover, metformin treatment significantly decreased the elevated serum levels of glycosylated hemoglobin, high, low, and very low-density lipoproteins, adipokines (visfatin and resistin), and retinol-binding protein-4 expression, with a significant increase in total cholesterol and triglycerides. Metformin also reduced the proinflammatory cytokine expressions (interleukin-1β, interferon-γ, and tumor-necrosis factor-α). In conclusion, metformin can alleviate adipocytokines through anti-inflammatory effects, synergizing with its antidiabetic actions.

Abstract
Type 2 Diabetes Mellitus (T2DM) has been the main category of metabolic diseases in recent years due to changes in lifestyle and environmental conditions such as diet and physical activity. On the other hand, the circadian rhythm is one of the most significant biological pathways in humans and other mammals, which is affected by light, sleep, and human activity. However, this cycle is controlled via complicated cellular pathways with feedback loops. It is widely known that changes in the circadian rhythm can alter some metabolic pathways of body cells and could affect the treatment process, particularly for metabolic diseases like T2DM. The aim of this study is to explore the importance of the circadian rhythm in the occurrence of T2DM via reviewing the metabolic pathways involved, their relationship with the circadian rhythm from two perspectives, lifestyle and molecular pathways, and their effect on T2DM pathophysiology. These impacts have been demonstrated in a variety of studies and led to the development of approaches such as time-restricted feeding, chronotherapy (time-specific therapies), and circadian molecule stabilizers.

[PMID: 34579756 PMCID: PMC8477540 DOI: 10.1186/s13020-021-00479-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Accepted: 07/28/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND The Gouqi-wentang formula (GQWTF) is a herbal formula used by Academician Xiao-lin Tong for the clinical treatment of T2DM. GQWTF is beneficial to qi, nourishes Yin, clears heat, and promotes fluid production, but the effective components and their mechanism of action remain unclear. METHODS The main components of GQWTF were detected by LC-MS, and the multi-target mechanisms of GQWTF in T2DM were elucidated using network pharmacology analysis, including target prediction, protein-protein interaction network construction and analysis, Gene Ontology (GO) terms, Kyoto Encyclopaedia of Genes and Genomes (KEGG) pathway annotation, and other network construction. Finally, the efficacy of the GQWTF was verified using biological experiments. RESULTS First, the "herb-channel tropism" network suggested that GQWTF focuses more on treating diseases by recuperating the liver, which is considered as an important insulin-sensitive organ. Subsequently, a total of 16 active ingredients in GQWTF were detected and screened, and their biological targets were predicted. Then, "compound-target" network was constructed, where enrichment analysis of GQWTF targets reflected its potential pharmacological activities. After T2DM-related target identification, 39 cross targets of GQWTF and T2DM were obtained, and 30 key targets highly responsible for the beneficial effect of GQWTF on T2DM were identified by PPI analysis. GO analysis of these key targets showed that many biological processes of GQWTF in treating T2DM are key in the occurrence and development of T2DM, including components related to inflammatory/immune response, insulin, and metabolism. KEGG analysis revealed the regulation of multiple signalling pathways, such as insulin resistance, PPAR signalling pathway, FoxO signalling pathway, Fc epsilon RI signalling pathway, and pathways that influence diabetes primarily by regulating metabolism as well as other T2DM directly related pathways. Furthermore, a "formula-compound-pathway-symptom" network was constructed to represent a global view of GQWTF in the treatment of T2DM. CONCLUSIONS This study explored the mechanism of action of GQWTF in T2DM by multi-component and multi-target multi pathways, which could provide a theoretical basis for the development and clinical application of GQWTF.

JOURNAL OF ETHNOPHARMACOLOGY 2021; 274:114056.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Fufang Zhenzhu Tiaozhi formula (FTZ) of which a patented preparation of Chinese herbal medicine has been well documented with significant clinical curative effect for hyperglycemia and hyperlipidemia. Because of the complexity of the chemical constituents of Chinese herbal formulas, the holistic pharmacological mechanism of FTZ acting on type 2 diabetes mellitus (T2DM) and nonalcoholic fatty liver disease (NAFLD) remains unclear. AIM OF THE STUDY To investigate the pharmacological efficacy and mechanism of FTZ in the treatment of T2DM accompanied by NAFLD. MATERIALS AND METHODS Network pharmacology and validation in minipigs were used in this study. First, potential bioactive compounds of FTZ were identified by the traditional Chinese medicine system pharmacology technology platform (TCMSP). Then, targets of compounds were gathered using DrugBank, SwissTargetPrediction and TCMSP, while targets for T2DM and NAFLD were collected from CTD (compounds-targets-diseases network) and GeneCards. Common targets were defined as direct therapeutic targets acting on T2DM with NAFLD. In addition, crucial targets were chosen by the protein-protein interaction (PPI) network and contribution to compound-therapeutic targets in T2DM with the NAFLD network. Furthermore, gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to analyze the metabolism-related signaling pathways affected by FTZ. Candidate patterns selected by network pharmacology were tested in the minipigs model of T2DM with NAFLD. Measurements of triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), fasting insulin (FINS) and fasting blood glucose (FBG) in the blood and the expression levels of proteins, including PI3K-AKT and HIF-1α, in the livers of the minipigs were followed by the administration of FTZ. RESULTS A total of 116 active compounds and 82 potential targets related to T2DM and NAFLD were found. Pathway and functional enrichment analysis showed that FTZ mainly regulates metabolism-related pathways, including PI3K-AKT, HIF-1α, TNFα and MAPK. Animal experiments showed that FTZ treatment significantly reduced the serum levels of TG, TC, LDL-C and FBG, increased serum levels of HDL-C, ameliorated systemic insulin resistance (IR), and attenuated liver damage in minipigs with T2DM and NAFLD. FTZ treatment has an obviously favorable influence on hepatic steatosis and liver lipid accumulation in the histopathologic features of HE, Oil red O staining, and electron microscopy. Mechanistically, FTZ improved liver metabolism by increasing the phosphorylation of PI3K-AKT and decreasing the expression of HIF-1α. CONCLUSION Network pharmacology was supported by experimental studies, which indicated that FTZ has demonstrated therapeutic benefits in T2DM and NAFLD by regulating the PI3K-AKT and HIF-1α signaling pathways.

Abstract
AIMS/HYPOTHESIS Besides serving as a traditional inflammatory marker, C-reactive protein (CRP) is closely associated with the development of obesity, diabetes and cardiovascular diseases as a metabolic and inflammatory marker. We hypothesise that CRP protein directly participates in the regulation of energy and glucose metabolism rather than just being a surrogate marker, and that genetic deficiency of CRP will lead to resistance to obesity and insulin resistance. METHODS Crp gene deletion was achieved by transcription activator-like effector nuclease (TALEN) technology in rats. The Crp knockout animals were placed on either a standard chow diet or a high-fat diet. Phenotypic changes in body weight, glucose metabolism, insulin sensitivity, energy expenditure and inflammation condition were examined. The central impact of CRP deficiency on leptin and insulin hypothalamic signalling, as well as glucose homeostasis, were examined via intracerebral ventricular delivery of leptin and CRP plus glucose clamp studies in the wild-type and Crp knockout rats. RESULTS CRP deficiency led to a significant reduction in weight gain and food intake, elevated energy expenditure and improved insulin sensitivity after exposure to high-fat diet. Glucose clamp studies revealed enhanced hepatic insulin signalling and actions. Deficiency of CRP enhanced and prolonged the weight-reducing effect of central injected leptin and promoted the central and peripheral roles of leptin. By contrast, reinstatement of CRP into the hypothalamus of the knockout rats attenuated the effects of central leptin signalling on insulin sensitivity and peripheral glucose metabolism. CONCLUSIONS/INTERPRETATION This study represents the first line of genetic evidence that CRP is not merely a surrogate blood marker for inflammation and metabolic syndromes but directly regulates energy balance, body weight, insulin sensitivity and glucose homeostasis through direct regulation of leptin's central effect and hypothalamic signalling.

Abstract
In vitro digestion of curdlan oligosaccharides (COSs), pullulan oligosaccharides (POSs), xanthan gum oligosaccharides (XGOSs) and gellan gum oligosaccharides (GGOSs) was investigated. These four oligosaccharides showed resistance to simulated saliva and gastric and small intestinal fluid. In further fermentation with faecal microbiota from healthy subjects and type 2 diabetes (T2D) patients, COS fermentation significantly increased the abundance of Bifidobacterium spp. and Lactobacillus spp. and the production of short-chain fatty acids in healthy and T2D groups. Digestion of XGOS enhanced the growth of the Clostridium leptum subgroup and significantly increased butyric acid production in healthy and T2D groups. Sole fermentation with COS, POS, XGOS and GGOS exhibited different metabolic profiles between healthy and T2D groups, and more small molecule polyols were produced in the T2D group than in the healthy group. This study provides a novel perspective on the reconstruction of gut microbiota and metabolism by POS, COS, GGOS and XGOS intervention.

Abstract
Type 2 diabetes mellitus (T2DM) is a metabolic disorder associated with insulin resistance and hyperglycemia. Chronic exposure to a T2DM microenvironment with hyperglycemia, hyperinsulinemia, oxidative stress and increased levels of proinflammatory mediators, has negative consequences to the cardiovascular system and mental health. Therefore, atherosclerotic cardiovascular diseases (CVD) and mental health issues have been strongly associated with T2DM. Lifestyle modifications, including physical exercise training, are necessary to prevent T2DM development and its associated complications. It is widely known that the regular practice of exercise provides several physiological benefits to subjects with T2DM, such as managing glycemic and blood pressure levels. Different types of exercise, from aerobic to resistance training, are effective to improve mental health and cognitive function in T2DM. Irisin is a myokine produced in response to exercise, which has been pointed as a relevant mechanism of action to explain the benefits of exercise on cardiovascular and mental health in T2DM patients. Here, we review emerging clinical and experimental evidence about exercise-linked irisin consequences to cardiovascular and mental health in T2DM.

Abstract
Psoriasis is a chronic skin immune-mediated disease with systemic pro-inflammatory activation; both genetic and lifestyles factors contribute to its pathogenesis and severity. In this context, nutrition plays a significant role, per se, in psoriasis' pathogenesis. Obesity is another important risk factor for psoriasis, and weight reduction may improve psoriasis' clinical severity. The excess body weight, particularly visceral fat mass, can affect both drug's pharmacokinetics and pharmacodynamics. Therefore, psoriasis and obesity share a certain degree of synergy, and the chronic inflammatory state represents the basis of this vicious cycle. Evidence reported that nutrition has different impact on the clinical severity of psoriasis, though some specific diets have been more investigated in clinical studies compared to others. Diets with systemic anti-inflammatory properties seem to have a higher effect on improving the clinical severity of psoriasis. Of interest, very-low-calorie ketogenic diet (VLCKD), through the production of ketone bodies, has been associated with both a significant reduction of body weight and inflammatory state. VLCKD leading to both weight loss and reduction of systemic inflammation may decrease the exacerbation of the clinical manifestations or even it may block the trigger of psoriatic disease. This dietary pattern could represent a potential first-line treatment in psoriatic patients with obesity. The review aims to summarize the current evidence regarding VLCKD and psoriasis with specific reference to antioxidant and anti-inflammatory effects of this dietary pattern.

Abstract
Global rise in obesity-associated type 2 diabetes mellitus (T2DM) has led to a major healthcare crisis. Development of efficient treatments to treat the underlying chronic inflammation in obesity-associated T2DM, is an unmet medical need. To this end, we have developed a plasmid adiponectin (pADN) based nanomedicine for the treatment of insulin resistance in type 2 diabetes mellitus. Adiponectin is a potent anti-inflammatory/anti-diabetic adipokine, which is downregulated in obesity. In this study, nanomicelles comprising chitosan conjugated to oleic acid and adipose homing peptide (AHP) were developed to deliver pADN to adipocytes. Cationic chitosan-oleic-AHP micelles were 112 nm in size, encapsulated 93% of pADN and protected gene cargo from DNase I mediated enzymatic degradation. In vitro, the nanomicellar formulation significantly increased adiponectin production compared to free plasmid as well as standard transfecting agent FuGENE®HD. Single dose subcutaneous administration of pADN-chitosan-oleic-AHP to obese-diabetic rats, resulted in improved insulin sensitivity for up to 6 weeks, which matched the glucose disposal ability of healthy rats. Serum adiponectin level in pADN-chitosan-oleic-AHP treated rats was comparable to healthy rats for up to 3 weeks post treatment. Overall, the results indicate that pADN-chitosan-oleic-AHP based therapy is a promising treatment approach for obesity-associated T2DM.
