Hepatic fibrosis is not only a pathological process of hepatic self-repair after chronic liver injury, but also a critical stage in the progression of chronic liver disease to liver cirrhosis. Studies have shown that as a pro-inflammatory form of programmed cell death, pyroptosis plays an important role in various diseases and is also considered a potential therapeutic target for hepatic fibrosis. This article systematically reviews the association of pyroptosis in hepatocytes, hepatic stellate cells, and hepatic macrophages with hepatic fibrosis and discusses pyroptosis-mediated therapeutic strategies targeting hepatic fibrosis.

Steroid-induced avascular necrosis of femoral head(SANFH) is a bone and joint disease caused by prolonged and excessive steroid use. Its typical pathological features involve progressive circulatory disorders in the blood supply system of femoral head, leading to osteocyte apoptosis and bone tissue necrosis. As the disease progresses, it ultimately results in structural collapse and necrotic lesions of the femoral head, severely affecting patients' limb function and quality of life. Glucocorticoids mediate pathological damage through dual mechanisms, on the one hand, they disrupt the dynamic equilibrium between bone formation and resorption by suppressing osteoblast differentiation activity and activating osteoclastogenesis, on the other hand, they induce lipid metabolism disorders, inhibit angiogenesis, and impair endothelial cell function, thereby triggering microcirculatory disorders. Epimedii Folium and its active components exhibit multidimensional regulatory effects in SANFH prevention and treatment. Literature review reveals that it is rich in multiple active ingredients, primarily including total flavonoids of Epimedii Folium, icaritin, icariin, kaempferol, icariside Ⅱ, etc. These compounds exert multiple pharmacological effects(regulating bone metabolic homeostasis, modulating angiogenesis, correcting lipid metabolism disorders, and controlling cellular autophagy processes) through multiple signaling pathways, including Wnt/β-catenin, transforming growth factor(TGF)-β/bone morphogenetic protein(BMP)/Smad, mitogen-activated protein kinase(MAPK), phosphoinositide 3-kinase/protein kinase B(PI3K/Akt), osteoprotegerin/receptor activator of nuclear transcription factor-κB ligand/receptor activator of nuclear transcription factor-κB(OPG/RANKL/RANK), etc. Based on existing research findings, this paper systematically elucidates the intervention mechanisms of active components in Epimedii Folium on key pathological processes of SANFH through the above pathways. It also deeply analyzes their regulatory roles in key nodes of different signaling pathways, aiming to provide valuable references for future clinical treatment and experimental research.

This paper comprehensively discusses on the potential neurobiological mechanisms of acupuncture in the treatment of tobacco dependence, focusing on three important aspects, including acupuncture's regulation of tobacco dependence behavior, effects of acupuncture on withdrawal syndrome, and the role of acupuncture in preventing relapse. It is found that acupuncture can inhibit drug-seeking behavior by regulating the reward pathway and related neurons, such as dopamine, thus modulating tobacco dependence behavior. It also alleviates withdrawal symptoms by improving the oral environment of smokers and reducing negative emotions after quitting. Furthermore, acupuncture can prevent relapse by decreasing brain network activity related to smoking cravings and improving cognitive brain functions like addiction memory. Currently, research on the specific neurobiological mechanism of acupuncture in treating tobacco dependence and the involved neural circuits is limited. Future research directions are proposed, including the evaluation of clinical effects, exploration of specific therapeutic mechanisms, investigation of brain pathology, and strengthening the exploration of brain functions. Additionally, combining modern technologies to clarify the neural circuits involved in acupuncture intervention will provide a basis for acupuncture treatment of tobacco addiction.

ObjectiveTo establish a rapid analytical method for identifying the differential components in Poria cocos medicinal materials based on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Orbitrap-MS), combined with mass defect filtering(MDF) and molecular network integration techniques. MethodsUPLC-Q-Orbitrap-MS was used for MS data acquisition and identification of P. cocos medicinal materials, with the help of MDF for the study of cleavage behavior and structural identification of triterpenoids. According to the similarity of MS/MS fragmentation patterns of each component, global natural product social molecular network(GNPS) was established, and Cytoscape 3.6.1 was used to screen molecular clusters with similar structures and the the structure of main compound classes were identified and confirmed. Multivariate statistical analyses such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to screen the differential components of the five P. cocos medicinal materials with the variable importance in the projection(VIP) value>1 and P<0.05 as the criteria. ResultsA total of 66 compounds were identified by database comparison, 8 compounds were newly identified by MDF, 28 compounds were newly identified by GNPS, and a total of 102 chemical compounds were identified, including 43 triterpenoids, 16 saccharides, 26 amino acids and peptides, 3 nucleosides, and 14 other compounds. Triterpenoids were predominant in Poriae Cutis and wild Fushen, amino acids and peptides were the most abundant in Poria and cultivated Fushen, carbohydrates were the most abundant in Poriae Cutis. Type Ⅰ and Ⅱ triterpenoids had higher amounts in Poria and cultivated Fushen, type Ⅲ triterpenoids were more abundant in Poriae Cutis, all four types of triterpenoids were higher in Fushenmu, and type Ⅰ, Ⅱ, and Ⅳ triterpenoids were higher in wild Fushen. A total of 12 common differential chemical constituents were screened, including serine, guanosine, gallic acid, 2-octenal, maltotriose, trametenolic acid, dehydroeburicoic acid, dehydrotrametenolic acid, poricoic acid A, poricoic acid B, poricoic acid E and G, but the relative contents of them varied significantly among different medicinal materials. ConclusionAmong the five P. cocos medicinal materials, the types of constituents are generally similar, but their relative contents differed significantly among these medicinal materials, especially in the distribution of triterpenoids. The integration of UPLC-Q-Orbitrap-MS, MDF and GNPS can provide a reference for the rapid qualitative analysis of other Chinese medicines.

ObjectiveTo explore the mechanism of Yishen Huashi granules in alleviating renal tubular epithelial cell injury and relieving diabetic kidney disease by regulating the mitogen-activated protein kinase (MAPK) signaling pathway. MethodsThe db/db mice of 12 weeks old were randomly assigned into model , dapagliflozin (1.6 mg·kg-1), and Yishen Huashi granules (4.7 g·kg-1), and db/m mice were used as the control group. The general conditions of mice were observed, and fasting blood glucose and 24-h urinary protein and albumin-to-creatinine ratio (ACR) were measured at weeks 0 and 12 of administration. After 12 weeks of treatment, the levels of serum creatinine (SCr), blood urea (UREA), triglycerides (TG), total cholesterol (TC), and low density lipoprotein (LDL) were measured. The pathological changes in the renal tissue were observed by hematoxylin-eosin (HE) staining, Periodic acid-Schiff (PAS) staining, Mallory staining, and transmission electron microscopy. Real-time PCR was employed to determine the mRNA levels of monocyte chemotactic protein-1 (MCP-1) and CC chemokine receptor-2 (CCR2) in the renal tissue of mice. The immunohistochemical assay was employed to examine the expression of p38, phospho-p38 (p-p38), MCP-1, and CCR2 in the renal tissue of mice. Western blotting was employed to measure the protein levels of p-p38, p38, MCP-1, and CCR2 in the renal tissue of mice.HK-2 cells cultured in vitro were grouped as follows: negative control, high glucose(30 mmol·L-1), Yishen Huashi granule-containing serum, and SB203580. After 48 h of cell culture in each group, RNA were extracted and the levels of MCP-1, and CCR2 mRNA were determined by Real-time PCR,proteins were extracted and the levels of p38, p-p38, MCP-1, and CCR2 were determined by Western blot. ResultsThe in vivo experiments showed that before treatment, other groups had higher body weight, blood glucose level, 24 h urinary protein, and ACR than the control group (P<0.05,P<0.01). After 12 weeks of treatment, compared with the model group, the Yishen Huashi granules group showed improved general conditions, a decreasing trend in body weight, lowered levels of blood glucose, 24-h urinary protein, and ACR (P<0.01), reduced SCr and UREA (P<0.01), and declined levels of TC, TG, and LDL (P<0.05,P<0.01). Compared with the model group, the Yishen Huashi granules group showed alleviated damage and interstitial fibrosis in the renal tissue as well as reductions in glomerular foot process fusion and basement membrane thickening. Moreover, the Yishen Huashi granules group showed down-regulated mRNA levels of MCP-1 and CCR2 (P<0.01), reduced positive expression of p-p38, MCP-1, and CCR2 (P<0.01), and down-regulated protein levels of p-p38/p38, MCP-1, and CCR2 (P<0.05) in the renal tissue. The cell experiment showed that compared with the high glucose group, the Yishen Huashi granule-containing serum group showcased down-regulated mRNA levels of MCP-1 and CCR2 (P<0.01) and down-regulated protein levels of p-p38/p38, MCP-1, and CCR2(P<0.05,P<0.01). ConclusionYishen Huashi granules can regulate glucose-lipid metabolism, reduce 24 h urinary protein and ACR, improve the renal function, alleviate the renal tubule injury caused by high glucose, and protect renal tubule epithelial cells in db/db mice by reducing MCP-1/CCR2 activation via the p38 MAPK signaling pathway.

[Objective] To explore the predictive value of HALP score for prognosis in patients with multiple myeloma (MM). [Methods] A retrospective analysis was conducted on laboratory indicators and related clinical data of newly diagnosed multiple myeloma (NDMM) patients, treated at the Affiliated Hospital of North Sichuan Medical College from January 2016 to October 2023, prior to their first treatment. The HALP score was calculated, and the optimal cutoff value for HALP was determined using X-tile software. Survival analysis was performed using Kaplan-Meier curves for high HALP and low HALP groups. Univariate and multivariate analyses were conducted using the Cox regression model, and a forest plot was generated using Graphpad Prism to illustrate factors that may impact patient prognosis. The predictive ability of HALP score combined with β2-microglobulin and ECOG score for prognosis in MM patients was evaluated using receiver operating characteristic curve (ROC) analysis. [Results] A total of 203 MM patients were included, with the optimal cutoff value for HALP score being 29.15 (P<0.05). Among them, 101 patients were in the low HALP score group, and 102 patients were in the high HALP score group. The results of univariate and multivariate analysis using the Cox regression model showed that a HALP score <29.15 was an independent risk factor for progression-free survival (PFS) and overall survival (OS) (P<0.05). ROC curve analysis indicated that the combination of HALP score with β2-microglobulin and ECOG score had a higher predictive value for prognosis in MM patients compared to using HALP score alone. [Conclusion] The HALP score is closely related to the prognosis of patients with NDMM. A low HALP score indicates a poorer prognosis, while the combination of HALP score with β2-microglobulin and ECOG score provides a higher predictive value when assessed together.
