ObjectiveThis study aims to elucidate the potential mechanism of Zuojinwan in improving liver fibrosis through hepatic tissue metabolomics analysis. MethodsTwenty-four mice were randomly allocated into normal group, model group , positive drug group (silymarin, 100 mg·kg-1), and Zuojinwan group (Zuojinwan solution, 2.5 g·kg-1), with per group six mice. Liver fibrosis model was induced via intraperitoneal injection of olive oil solution with 10% carbon tetrachloride (CCl4) (0.5 μL·g-1, three times weekly for 8 weeks) in all groups except the normal group. During the final 4 weeks, the silymarin group received silymarin (100 mg·kg-1) by gavage thrice weekly, while the Zuojinwan group was administered Zuojinwan solution (2.5 g·kg-1) under the same regimen. After the last administration, the levels of liver fibrosis indicators and liver injury markers in serum were detected. The pathological morphological changes of the liver tissues were observed. The levels of liver fibrosis markers α-smooth muscle actin (α-SMA) and Collagen Ⅰ(ColⅠ) were detected. Metabolomics was analyzed on mice's liver tissues. The mice's serum was collected for metabolomics analysis. ResultsCompared with the model group, Zuojinwan significantly improved indicators related to liver fibrosis and liver injury. Compared with the normal group, the model group showed significantly elevated levels of fibrosis markers such as laminin (LN), hyaluronic acid (HA), procollagen typeⅢ (PC-Ⅲ), and type Ⅳ Collagen (Ⅳ-C), while liver injury indicators such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and total bilirubin (TBIL), exhibited a marked upward trend (P<0.05). Compared with the model group, the silymarin group showed a significant decrease in the aforementioned indicators (P<0.05). Notably, compared with the model group, the Zuojinwan group exhibited a significant reduction in all these indicators (P<0.05), with efficacy comparable to that of the silymarin group. Zuojinwan reduced mRNA and protein levels of α-SMA and ColⅠ in the liver tissue. Metabolomics results revealed that compared with the model group, Zuojiinwan significantly reduced levels of glucose metabolism-related metabolites such as D-fructose 1,6-bisphosphate (FBP), nicotinamide adenine dinucleotide phosphate (NADPH), sodium beta-D-fructose 6-phosphate (F6P), dihydroxyacetone phosphate (DHAP), fumaric acid, and D-glucose 6-phosphate (G6P) (P<0.05). Serum enzyme-linked immunosorbent assay (ELISA) was used to detect glucose metabolism indicators and further validate the regulatory effect of Zuojinwan on glucose metabolism. ConclusionThese results suggest that Zuojinwan may improve liver fibrosis by regulating the dysregulated levels of glucose metabolism during the progression of liver fibrosis.

Neurodegenerative diseases (NDDs) are a group of heterogeneous neurological disorders that can cause progressive loss of neurons in the central nervous system or peripheral nervous system, resulting in a decline in motor function. Motion capture, as a high-precision and high-resolution technology for capturing human motion data, drives NDDs motor assessment to effectively extract kinematic features and thus assess the patient's motor ability or disease severity. This paper focuses on the recent research progress in motor assessment of NDDs driven by motion capture data. Based on a brief introduction of NDDs motor assessment datasets, we categorized the assessment methods into three types according to the way of feature extraction and processing: NDDs motor assessment methods based on statistical analysis, machine learning and deep learning. Then, we comparatively analyzed the technical points and characteristics of the three types of methods from the aspects of data composition, data preprocessing, assessment methods, assessment purposes and effects. Finally, we discussed and prospected the development trends of NDDs motor assessment.

OBJECTIVES:
Psoriasis is a chronic inflammatory skin disease often accompanied by comorbidities such as hyperglycemia, insulin resistance, and obesity. Acitretin, as a second-generation retinoid, is used in the treatment of psoriasis. This study aims to explore the role of acitretin on glucose and lipid metabolism in psoriasis.
METHODS:
HepG2 cells were treated with acitretin under high- or low-glucose conditions. mRNA and protein expression levels of glucose transport-related genes were evaluated using real-time reverse transcription PCR (real-time RT-PCR) and Western blotting. Glucose uptake was analyzed by flow cytometry, and intracellular lipid droplet formation was assessed via Oil Red O staining. Healthy adult female BALB/C mice were randomly divided into 3 groups: a control group, an imiquimod (IMQ)-induced psoriasis model group (IMQ group), and an acitretin treatment group. Skin lesions and inflammatory markers were examined, along with changes in body weight, plasma glucose/lipid levels, and transcription of metabolic genes. Islets were isolated from normal and psoriasis-induced mice, and the effect of acitretin on insulin secretion was evaluated in vitro.
RESULTS:
Acitretin treatment increased glucose uptake and lipid droplet synthesis of HepG2 in high-glucose environment, with elevated transcription levels of glucose transport-related genes GLUT1 and GLUT4. Transcription of gluconeogenesis-related gene G6pase decreased, while transcription levels of glycogen synthesis-related genes AKT1 and GSY2 increased (all P<0.05), while acitretin inhibits glucose uptake and promotes gluconeogenesis in low-glucose environment. In vivo experiments revealed that compared with the control group, the blood glucose level in the IMQ group was significantly decreased (P<0.05), while acitretin treatment partially restored glucose homeostasis and alleviated weight loss. Ex vivo culture of islets from psoriatic mice revealed that acitretin reduced elevated insulin secretion and downregulated PDX-1 expression, while upregulating glucose homeostasis gene SIRT1 and insulin sensitivity gene PPARγ (all P<0.05). These findings suggest that acitretin plays a critical role in improving islet function and restoring islet homeostasis.
CONCLUSIONS
Acitretin helps maintain the balance between hepatic glycogenesis and gluconeogenesis, enhances insulin sensitivity, and improves pancreatic islet function, thereby promoting systemic and cellular glucose homeostasis.

Dry eye disease (DED) is a prevalent and intractable ocular disease induced by a variety of causes. Elevated sphingomyelin (SM) levels and pro-inflammatory cytokines were detected on the ocular surface of DED patients, particularly in the meibomian glands. Sphingomyelin synthase 2 (SMS2), one of the proteins involved in SM synthesis, would light a novel way of developing a DED therapy strategy. Herein, we report the design and optimization of a series of novel thiophene carboxamide derivatives to afford 14l with an improved highly potent inhibitory activity on SM synthesis (IC50, SMS2 = 28 nmol/L). Moreover, 14l exhibited a notable protective effect of anti-inflammation and anti-apoptosis on human corneal epithelial cells (HCEC) under TNF-α-hyperosmotic stress conditions in vitro, with an acceptable ocular specific distribution (corneas and meibomian glands) and pharmacokinetics (PK) profiles (t 1/2, cornea = 1.11 h; t 1/2, meibomian glands = 4.32 h) in rats. Furthermore, 14l alleviated the dry eye symptoms including corneal fluorescein staining scores and tear secretion in a dose-dependent manner in mice. Mechanically, 14l reduced the mRNA expression of Tnf-α, Il-1β and Mmp-9 in corneas, as well as the proportion of very long chain SM in meibomian glands. Our findings provide a new strategy for DED therapy based on selective SMS2 inhibitors.

Hepatic ischemia-reperfusion injury (HIRI) has been considered as an inevitable process of liver transplantation. Hepatocyte ferroptosis is a key factor in HIRI development, yet precise mechanism and potential therapies are still unclear. Here, we demonstrated a strong correlation between hepatocyte ferroptosis and the downregulation of poly(rC)-binding protein (PCBP2), which compromised the stability of antiporter system Xc- (consisted of SL3A2/SLC7A11). Besides, inhibiting PCBP2 contributed to facilitating cofactor p300 to enhance the transcriptional activity of HIF1α, leading to the expression and secretion of HMGB1. Then, released HMGB1 from ferroptotic hepatocytes worsened M1 macrophage recruitment and immune response during HIRI. Additionally, acteoside (ACT) was shown to assist PCBP2 in stabilizing the mRNA stability of Slc3a2 and Slc7a11, as well as enhance the binding affinity of PCBP2-system Xc-. Beyond that, ACT also supported PCBP2 to limit HMGB1-induced M1 macrophage recruitment through imposing restrictions on p300 and HIF1α. Furthermore, specific knockdown of PCBP2 in hepatocytes directly interposed the therapeutic efficacy of ACT on HIRI mice. In conclusion, ACT alleviated hepatocyte ferroptosis and HIRI via promoting PCBP2 to maintain the stability of system Xc- and limit HIF1α/p300-HMGB1 signaling. These findings highlight the therapeutic benefits of ACT in treating HIRI and offer insights into innovative therapeutic strategies.

Lirispirolides A-L (1-12), twelve novel sesquiterpene-monoterpene heterodimers featuring distinctive carbon skeletons, were isolated from the branches and leaves of Chinese tulip tree [Liriodendron chinense (L. chinense)], a rare medicinal and ornamental plant endemic to China. The structural elucidation was accomplished through comprehensive spectroscopic analyses, quantum-chemical calculations, and X-ray crystallography. These heterodimers exhibit a characteristic 2-oxaspiro[4.5]decan-1-one structural motif, biosynthetically formed through intermolecular [4 + 2]-cycloaddition between a germacrane-type sesquiterpene and an ocimene-type monoterpene. The majority of the isolated compounds demonstrated significant anti-neuroinflammatory effects in lipopolysaccharide (LPS)-induced BV-2 microglial cells by reducing the production of pro-inflammatory mediators, specifically tumor necrosis factor-α (TNF-α) and nitric oxide (NO). Further investigation revealed that the lirispirolides' inhibition of NO release correlated with decreased messenger ribonucleic acid (mRNA) expression of inducible NO synthase (iNOS).

Diabetes mellitus (DM) is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells, posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs, including the eyes, heart, liver, kidneys, nerves, and feet, making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications, challenges such as high costs and adverse drug reactions remain. Thus, identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component, astragaloside Ⅳ, possesses various biological activities, including anti-inflammatory, antioxidant, and antiviral effects, as well as benefits for cardiac and cerebral function, nerve conduction, and myocardial protection. Meanwhile, the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway plays a crucial role in regulating oxidative stress, inflammatory responses, apoptosis, and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications, leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally, it highlights its protective effects on basic cardiac function, inhibition of retinal cell damage, improvement of cerebral nerve dysfunction, reduction of chronic kidney and liver damage, and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer, astragaloside Ⅳ, in the treatment of DM and its complications.
