Chronic pancreatitis is an inflammatory disease and is difficult to manage despite advancements in medical science. This study examined the effect of water/ethanol extracts of Justicia carnea leaves on oxidative stress and glucagon expression in a mouse model of chronic pancreatitis induced by trinitrobenzenesulfonic acid (TNBS).

Twenty-five male Swiss albino mice were randomized and treated intrarectally with vehicle (the control group) or TNBS. Some TNBS-treated mice were treated orally with 200 mg/kg or 400 mg/kg J. carnea extracts, or with the positive control, 500 mg/kg sulfasalazine, every other day on three occasions. Oxidative stress markers and pancreatic glucagon expression were assessed.

Compared with the healthy control mice, treatment with TNBS significantly decreased the levels of pancreatic glutathione (0.89 µmol/g tissue vs. 7.16 µmol/g tissue in the control) and glutathione peroxidase activity, but significantly increased the levels of α-amylase and lipase activities, lipid peroxidation, total antioxidant capacity, and nitric oxide, as well as serum C-reactive protein (P < 0.05 for all), accompanied by severe inflammation and reduced glucagon expression in the pancreatic tissues. The toxic effects of TNBS were significantly mitigated by treatment with J. carnea extracts.

These findings provide evidence that treatment with J. carnea extracts inhibited oxidative stress and preserved glucagon expression in the pancreatic tissues of mice.

Acute liver failure (ALF) is a severe hepatic injury associated with high short-term mortality. Our previous study found that 1,5-anhydroglucitol (1,5AG) levels correlate with clinical outcomes in patients with liver failure. This study aimed to explore the potential effects and mechanisms of 1,5AG in ALF.

An experimental model of ALF was established using LPS and D-GalN. 1,5AG was administered to mice by gavage before modeling. Empagliflozin was then administered to reduce 1,5AG levels in mice. Peroxisome proliferator-activated receptor alpha (PPARα) agonists were also used to explore the role of 1,5AG in mice with liver failure.

1,5AG pretreatment significantly increased ALT and AST levels, aggravated histological damage and hepatocyte apoptosis, and increased mortality in ALF mice. Transcriptomic analysis and western blot validation revealed that 1,5AG significantly inhibited the PPARα signaling pathway and its downstream target, fibroblast growth factor 21. Empagliflozin treatment reduced 1,5AG levels, alleviated liver injury and hepatocyte apoptosis, and promoted the PPARα signaling pathway in ALF. PPARα agonists effectively reversed the effects of 1,5AG on ALF, thereby alleviating liver damage, pathological injury, and hepatocyte apoptosis.

1,5AG exacerbated liver injury in ALF mice by inhibiting the hepatic PPARα pathway, thereby promoting hepatocyte apoptosis.

Chronic stress-induced hypercortisolism causes diminished ovarian reserve (DOR), contributing to infertility and miscarriage. Androgen supplementation is an emerging therapeutic approach for DOR. The traditional Chinese herbal decoction modified Gengnianchun formula (MGNC) has shown clinical efficacy in treating DOR. This study aimed to compare the effectiveness of MGNC with that of androgens in a stress-induced DOR mouse model.

Sexually mature female C57 mice aged six weeks were randomly assigned to six groups (n = 10 per group, with 3 independent replicates per group), including the control, model, low-dose testosterone (LT), medium-dose testosterone (MT), high-dose testosterone (HT), and MGNC groups. This sample size and study design were determined based on preliminary experimental data. Chronic stress was induced in mice, except for the control group, by daily glucocorticoid injection, and the mice in the LT, MT, HT, and MGNC groups were treated at the same time with testosterone (low, medium, or high dose) or MGNC for six weeks. Body weight, estrous cycles, ovarian follicle counts, hormone profiles, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, and testosterone, and in vitro preantral follicle growth rates (via MGNC-enriched or androgen-treated serum) were assessed.

All groups presented stable body weights. MGNC ameliorated estrous cycle irregularities caused by stress, while testosterone exacerbated the abnormality. Moreover, MGNC outperformed LT in improving primordial/primary/antral follicle counts and corpus luteum formation, while MT and HT did not improve ovarian follicle reserve. LT was associated with the highest serum estradiol level, but none of the testosterone doses reduced FSH levels or the FSH/LH ratio, whereas MGNC lowered FSH and the FSH/LH ratio. Additionally, MGNC-enriched serum significantly enhanced the in vitro follicular growth rate in corticosterone-supplemented culture medium, and this effect was superior to that observed with testosterone-pretreated serum.

MGNC demonstrates superior efficacy over androgen therapy in treating chronic stress-induced DOR in mice, supporting further investigations into its clinical potential and mechanisms.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is an independent risk factor for cardiovascular disease (CVD). While gut bacteria have been linked to CVD, the role of intestinal fungi in subclinical coronary atherosclerosis (SCA) remains unclear. In this study, we aimed to investigate the association between the gut mycobiome and SCA in MASLD.

A cross-sectional study was conducted among 103 MASLD patients without established CVD. Fibrosis and steatosis were assessed using magnetic resonance elastography (MRE) and proton density fat fraction, respectively. SCA was defined by coronary artery calcification (CAC). Fecal fungal composition was analyzed via internal transcribed spacer sequencing.

Mean age was 60.8 ± 11.2 years; 51.5% were men; 20.4% had cirrhosis. CAC correlated with MRE (r = 0.489, p < 0.001), interleukin-6 (r = 0.407, p < 0.001), and tumor necrosis factor-α (r = 0.254, p = 0.018), but not proton density fat fraction. Cirrhosis patients had higher CAC than F0–F3 (456.9 vs. 205.9, p = 0.033). Candida albicans (C. albicans) abundance was greater in cirrhosis and correlated with CAC (r = 0.403, p < 0.001) and MRE (r = 0.212, p = 0.032). In multivariate analysis, older age, diabetes, obesity, cirrhosis, and enriched C. albicans independently predicted CAC ≥ 100 AU in MASLD.

In MASLD, cirrhosis and C. albicans enrichment are independently associated with higher SCA burden, suggesting advanced liver disease and a potential fungal contribution to CVD pathogenesis.

Thalassemia is a group of anemias that result from inherited defects in the production of the beta chain of hemoglobin. It is stabilized by gamma globin, which combines to form fetal hemoglobin. One therapeutic approach is to target histone deacetylase (HDAC), which plays an important role in controlling beta thalassemia. This study sought to identify a natural inducer for treating this disease.

Twenty-five Andrographis paniculata compounds were screened using Schrödinger Suite 2020 (Maestro 12.3) for ligand preparation, grid generation, glide extra precision docking and molecular mechanics/generalized born surface area scoring. The HDAC2 crystal structure (Protein Data Bank ID: 4LXZ) was prepared by removing crystallographic water molecules and performing restrained minimization. Top-scoring complexes were subjected to 5-ns molecular dynamics simulations in GROMACS 2019 using the optimized potentials for liquid simulations force field, three interaction site point charge solvation, and standard neutralization and equilibration protocols. Absorption, distribution, metabolism, and excretion properties were predicted using QikProp.

Among the twenty five screened compounds, SRJ09 derivative of andrographolide, ranked among the top candidates based on glide extra precision docking and molecular mechanics/generalized born surface area scores and was therefore selected for further analysis. SRJ09 showed favorable binding to the HDAC2 active site, with interactions comparable to the reference inhibitor 20Y. Absorption, distribution, metabolism, and excretion predictions indicated acceptable drug-likeness, and molecular dynamics simulations demonstrated stable SRJ09–HDAC2 complex behavior over 5 ns.

We concluded that beta thalassemia may benefit from the use of andrographolide, and SRJ 09 as prospective HDAC2 inhibitor drugs that are favourable and efficacious and that generate fetal hemoglobin. Therefore, this bioactive compound is worth further investigation using in vitro and in vivo studies.

Combined traumatic brain injury (CTBI) remains a leading cause of disability/mortality among workers, yet which routine biochemical tests that predict infectious complications remain controversial. We aimed to identify the most informative serum markers for early diagnosis and prognosis of such complications.

In this retrospective observational study, 80 acute CTBI patients (40 without vs. 40 with mainly bacterial infectious complications) and 40 healthy controls were analyzed. Serum collected at 24, 72, and 168 h was assayed for protein fractions, metabolic markers, lipid peroxidation indices, antioxidant activity, endogenous intoxication markers, acids/minerals, and relevant enzymes.

The study found that the most important prognostic indicator for infectious complications was a simultaneous increase in α1-globulins, β-globulins, diene conjugates, superoxide dismutase, medium- and low-molecular-weight substances in erythrocytes, erythrocyte oligopeptides, and lactate at 24 h after injury (p < 0.001). A significant increase in sialic acids, uronic acids, total Ca and P, and low-density lipoproteins was observed at 72 h after injury (p < 0.001). Notably, individual components from the 24-h panel demonstrated high standalone predictive value, with areas under the curve of diene conjugates (0.91), erythrocyte oligopeptides (0.87), β-globulin (0.86), α1-globulin (0.82), and superoxide dismutase (0.82), respectively. The elevation of these biomarker profiles was significantly correlated with worse clinical outcomes, including longer intensive care unit stay and ventilation duration.

This study identified a set of biochemical markers associated with infectious complications in patients with CTBI. These biochemical parameters may serve as additional diagnostic and prognostic criteria for the management of infectious complications in patients with СTBI.

Hepatocellular carcinoma (HCC) is a malignant tumor with high incidence and mortality rates worldwide, in which immune evasion mechanisms play a crucial role in its progression and treatment. Natural killer group 2D ligands (NKG2DL), as key molecules activating immune cells, significantly influence the immune evasion of liver cancer through their regulatory mechanisms. This review summarizes the regulatory mechanisms of NKG2DL expression, including genetic, signaling pathway, non-coding RNA, and stress response modulation, and discusses their expression patterns and clinical relevance in HCC. Studies have shown that the expression status of NKG2DL not only impacts patient prognosis and therapeutic response but also provides potential targets for HCC immunotherapy. Future research should focus on the molecular networks regulating their expression and their synergy with immunotherapy to provide a theoretical basis for developing more precise diagnostic and personalized treatment strategies for HCC.

Cardiorenal syndrome is associated with high morbidity and mortality and is characterized by bidirectional interactions between cardiac and renal dysfunction. The advent of sodium-glucose cotransporter 2 inhibitors (SGLT2i) and the nonsteroidal mineralocorticoid receptor antagonist finerenone has substantially changed the therapeutic landscape. Combination therapy with SGLT2i and finerenone may provide additional benefits through complementary mechanisms, representing a potential paradigm shift in the management of cardiorenal syndrome. In this review, we examine the pathophysiological pathways that characterize cardiorenal syndrome, clinical data from major randomized controlled trials, and the rationale for the concomitant use of these two drug classes. SGLT2 inhibitors significantly reduce hospitalization for heart failure, slow renal function decline, and provide benefits in both heart failure with reduced ejection fraction and heart failure with preserved ejection fraction, irrespective of diabetes status. Finerenone has been shown to reduce the risk of cardiovascular events and chronic kidney disease progression in patients with type 2 diabetes and chronic kidney disease, with a more favorable safety profile than steroidal mineralocorticoid receptor antagonists. Emerging evidence suggests that combination therapy may reduce hospitalizations for heart failure and slow renal disease progression beyond the effects of either monotherapy. However, implementation of these therapeutic options requires careful patient selection, ongoing monitoring of renal function and electrolytes, and close collaboration between cardiologists and nephrologists.
