Parkinson's disease （PD） is a common neurodegenerative disorder characterized by motor impairments， with its pathological mechanisms involving multiple processes such as the degeneration of dopaminergic neurons and the abnormal aggregation of α-synuclein. Current Western medical treatments face challenges including diminished long-term efficacy and motor complications. In recent years， Traditional Chinese Medicine （TCM） has demonstrated advantages in the prevention and treatment of PD through its systematic regulatory capabilities， featuring multi-component， multi-target， and multi-pathway approaches.This article systematically reviews the roles of seven key signaling pathways-NF-κB， AMPK/mTOR， PI3K/Akt， MAPKs， Nrf2/ARE， Wnt/β-catenin， and BDNF/TrkB-in the pathological process of PD and the regulatory mechanisms of TCM. Research indicates that active ingredients of Chinese herbs and compound formulations can synergistically modulate these pathways， exerting comprehensive effects in inhibiting neuroinflammation， alleviating oxidative stress， promoting autophagy to clear abnormal proteins， and enhancing neurotrophic support. These signaling pathways form a complex regulatory network through crosstalk among key nodal molecules， constituting an intricate regulatory system in PD pathology. The multi-target intervention characteristics of TCM align well with this network-based regulatory requirement， achieving integrated anti-inflammatory， antioxidant， autophagy-regulating， and neurorestorative effects through synergistic multi-pathway modulation. This article systematically outlines the mechanisms of TCM in the coordinated regulation of multiple pathways， providing a theoretical basis for elucidating the pathological process of PD and the intervention mechanisms of TCM， while also offering new perspectives and directions for modern research on TCM in the prevention and treatment of PD.

This paper mainly discusses the pathogenesis of psoriasis,the establishment of animal models of psoriasis, the pharmacodynamics evaluation index of psoriasis drugs, and the research progress of current drugs related to interleukin(IL)-17 antagonists, aiming to provide certain references for the development of IL-17-related drugs and the treatment of psoriasis.

Objective:The aims of this study were to compare the clinical effectiveness of an immunosuppressant(sintilimab)combined with different chemotherapy regimens(two-and three-drug regimens)in the neoadjuvant treatment of advanced gastric cancer and to explore the efficacy-associated clinical features.Methods:A retrospective analysis was conducted on patients with advanced gastric cancer who re-ceived treatment at Lanzhou University Second Hospital between August 2020 and February 2024.Overall,133 patients were included in the study and assigned into groups A(three-drug regimens)and B(two-drug regimens),according to the treatment regimen received.Recent ef-ficacy outcomes,including the pathological complete response rate(pCR),major pathological response rate(MPR),objective response rate(ORR),and disease control rate(DCR),as well as long-term efficacy outcomes,including overall survival(OS)and disease-free survival(DFS),were compared.Subgroup analyses were performed to identify clinical features associated with treatment efficacy.Results:The recent effic-acy outcomes were similar between groups A(two-drug regimen)and B(three-drug regimen),with pCRs of 18.46%and 27.94%,MPRs of 52.31%and 58.82%,ORRs of 76.92%and 76.47%,and DCRs of 87.69%and 95.59%,respectively.However,the three-drug regimen led to significantly improved OS and DFS,compared with the two-drug regimen(P<0.05).Subgroup analysis revealed that male patients and those with gastric antrum cancer,an ECOG score of 0,a T4 stage tumor,and no vascular or nerve invasion benefited more from the three-drug re-gimen.Conclusions:Sintilimab combined with the three-drug chemotherapy regimen demonstrated superior long-term efficacy in the neo-adjuvant treatment of advanced gastric cancer,compared with the combination with the two-drug regimen.Certain clinical features may predict greater benefit from the three-drug regimen.

Objective:To investigate the effect of ginsenoside octanoate(Rh2-O)on inducing immunogenic cell death in hepa-tocellular carcinoma cells and its molecular mechanism.Methods:Effects of ginsenoside caprylate(Rh2-O)and autophagy inhibitor 3-MA on the activity of hepatocellular carcinoma cells were detected by CCK-8 assay.The effect of Rh2-O on CRT membrane eversion in Hepa1-6 cells were detected by immunofluorescence assay.Rh2-O treated mouse hepatocellular carcinoma cells were used to pre-pare a tumor vaccine for in vivo vaccination experiments in mice.Extracellular ATP levels were detected in real-time.The expression of autophagy-related genes and proteins were measured by real-time fluorescence PCR and Western blot,and the mitochondrial morphol-ogy and co-localization with autophagy proteins were observed by laser confocal microscopy.Results:Rh2-O showed strong cytotoxicity to Hepa1-6 cells[cell viability:(58.54±3.56)%]at a concentration of 150 μmol/L,and a large amount of CRT was observed on the surface of the cell membrane.The tumor emergence rate was 36.36%in the vaccinated group and 100%in the control group.The tumor vaccine prepared by Rh2-O effectively protected mice from the same type of tumor attack;Rh2-O induced an increase in the level of cellular secreted ATP(P<0.05),the mRNA of autophagy-related genes ATG3,p62,LC3 expression levels and autophagy-associated proteins LC3A and LC3B expression levels were increased(P<0.05),and co-localization of mitochondria with autophagy proteins was significantly increased(P<0.05).In addition,Rh2-O action on 3-MA pretreated hepatocellular carcinoma cells resulted in a signifi-cant decrease in extracellular ATP levels(P<0.001).Conclusion:Rh2-O may induce immunogenic cell death by inducing autophagy in hepatocellular carcinoma cells.

Objective:To analyze the clinical features associated with pelvic lymph node metastasis(PLNM)in prostate cancer and to construct a preoperative prediction model for PLNM,thereby reducing unnecessary extended pelvic lymph node dissection(ePLND).Methods:Based on predefined inclusion and exclusion criteria,344 patients who underwent radical prostatectomy and ePLND at the First Affilia-ted Hospital of Zhengzhou University between 2014 and 2024 were retrospectively enrolled,among whom,77 patients(22.4％)were pathologically confirmed to have lymph node-positive disease.The clinical characteristics,MRI reports,and pathological results were collected.The data were then randomly divi-ded into a training cohort(241 cases,70％)and a validation cohort(103 cases,30％).Univariate and multivariate Logistic regression analysis were employed to construct a preoperative prediction model for PLNM.Results:Univariate Logistic regression analysis revealed that total prostate specific antigen(tPSA)(P=0.021),free prostate specific antigen(fPSA)(P=0.002),fPSA to tPSA ratio(fPSA/tPSA)(P=0.011),percentage of positive biopsy cores(P＜0.001),prostate imaging reporting and data system(PI-RADS)score(P=0.004),biopsy Gleason score ≥8(P=0.005),clinical T stage(P＜0.001),and MRI-indicated lymph node involvement(MRI-LNI)(P＜0.001)were significant predictors of PLNM.Multivariate Logistic regression analysis demonstrated that the percentage of positive biopsy cores(OR=91.24,95％CI:13.34-968.68),PI-RADS score(OR=7.64,95％ CI:1.78-138.06),and MRI-LNI(OR=4.67,95％ CI:1.74-13.24)were independent risk factors for PLNM.And a novel nomogram for predicting PLNM was developed by integrating all these three variables.Com-pared with the individual predictors:percentage of positive biopsy cores[area under curve(AUC)=0.806],PI-RADS score(AUC=0.679),and MRI-LNI(AUC=0.768),the multivariate model incor-porating all three variables demonstrated significantly superior predictive performance(AUC=0.883).Consistently,calibration curves and decision curve analyses confirmed that the multivariable model had high predictive accuracy and provided significant net clinical benefit relative to single-variable models.And using a cutoff of 6％,the multiparameter model missed only approximately 5.2％of PLNM cases(4/77),while reducing approximately 53％of ePLND procedures(139/267),demonstrating favorable predictive efficacy.Conclusion:Percentage of positive biopsy cores,PI-RADS score and MRI-LNI are independent risk factors for PLNM.The constructed multivariate model significantly improves predictive efficacy,offering a valuable tool to guide clinical decisions on ePLND.

Carotid artery perivascular adipose tissue (PVAT) can influence plaque formation and progression. Recently, carotid artery PVAT density has emerged as a novel imaging biomarker being capable of reflecting local metabolic and inflammatory states of adipose tissue. It is closely associated with vulnerable plaque characteristics, such as intraplaque hemorrhage, thinning or rupture of the fibrous cap, lipid-rich necrotic core, and calcification. Therefore, carotid artery PVAT density holds promise as a key parameter for early identification of vulnerable carotid plaques and stroke risk prediction. This article reviews the definition and pathophysiological mechanism of PVAT and application of imaging techniques in PVAT, as well as the association between carotid artery PVAT density and vulnerable characteristics of plaques, with the aim of providing references for early identification of asymptomatic high-risk plaques and individualized prevention strategies of ischemic stroke.

Antimicrobial resistance(AMR)is a growing public health crisis that requires innovative solutions.Emerging multidrug resistant(MDR)Salmonella typhimurium has raised concern for its effect on path-ogenic infection and mortality in humans caused by enteric diseases.To combat these MDR Salmonella typhimurium pathogens,highly effective and broad-spectrum antibiotics such as flufenicol(FFC)need to be evaluated for their potent antibacterial activity against Salmonella typhimurium.However,the low solubility and low oral bioavailability of flufenicol need to be addressed to better combat AMR.In this work,we develop a novel nano-formulation,flufenicol nano-micelles(FTPPM),which are based on D-α-tocopherol polyethylene glycol 1,000 succinate(TPGS)/poloxamer 188(P188),for the targeted treatment of biofilms formed by drug-resistant Salmonella typhimurium in the intestine.Herein,FTPPM were prepared via a thin film hydration method.The preparation process for the mixed micelles is simple and convenient compared with other existing nanodrug delivery systems,which can further decrease pro-duction costs.The optimized FTPPM demonstrated outstanding stability and sustained release.An evaluation of the in vivo anti-drug-resistant Salmonella typhimurium efficacy demonstrated that FTPPM showed a stronger efficacy(68.17％)than did florfenicol-loaded TPGS polymer micelles(FTPM),flufenicol active pharmaceutical ingredients(FFC-API),and flufenicol commercially available medicine(FFC-CAM),and also exhibited outstanding biocompatibility.Notably,FTPPM also inhibited drug-resistant Salmonella typhimurium from forming biofilms.More importantly,FTPPM effectively restored intestinal flora dis-orders induced by drug-resistant Salmonella typhimurium in mice.In summary,FTPPM significantly improved the solubility and oral bioavailability of florfenicol,enhancing its efficacy against drug-resistant Salmonella typhimurium both in vitro and in vivo.FTPPM represent a promising drug-resistant Salmonella typhimurium treatment for curbing bacterial resistance via oral administration.

Objective:Based on a propensity score matchied analysis, the impact of neoadjuvant therapy, namely the transcatheter arterial chemoembolization (TACE) combined with the targeted and immunotherapy, on the prognosis of patients undergoing liver resection for hepatocellular carcinoma (HCC).Methods:Clinical data of 226 patients who underwent surgical resection for HCC of China Liver Cancer (CNLC) stage Ib, IIa, IIb, and IIIa at the Second Affiliated Hospital of Anhui Medical University from February 2020 to December 2024 were retrospectively analyzed, including 201 males and 25 females, aged 64.6±9.4 years. Patients were divided into the neoadjuvant therapy group ( n=25) and the direct surgery group ( n=201). Propensity score matching was used to analyze the liver fibrosis-4 score, platelet count, prothrombin time, activated partial thromboplastin time, and tumor number of the two groups. Postoperative pathological assessment of liver resection was performed. The Kaplan-Meier method was used to analyze the prognosis, and the log-rank test was used to compare the survival rates of the two groups. Results:After propensity score 1: 3 matching, there were no statistically significant differences (all P>0.05) regarding the baseline characteristics of the two groups. Pathological assessment after hepatectomy: the complete pathological response rate was 8% (2/25), and the major pathological response rate was 36% (9/25). The recurrence-free survival rates at 1, 2, and 3 years after surgery in the direct surgery group and the neoadjuvant therapy group were 52.0%, 48.0%, and 42.7% versus 76.0%, 72.0%, and 68.0%, respectively ( χ2=4.76, P=0.029). The overall survival rates at 1, 2, and 3 years after surgery in the direct surgery group and the neoadjuvant therapy group were 80.0%, 78.7%, and 77.3% versus 100.0%, 96.0%, and 96.0%, respectively ( χ2=4.31, P=0.038). Conclusion:Neoadjuvant therapy could reduce the risk of postoperative recurrence and prolong patients survival

Cognitive impairment is the main clinical manifestation of many nervous system diseases such as stroke,multiple sclerosis,and neurodegeneration,and neuroinflammation is one of the key mechanisms for the onset of cognitive disorders.Chemokines are a class of highly conserved small-molecule secretory proteins that bind to the corresponding chemokine receptors located on cell mem-brane,activating downstream signaling pathways and playing an important role in cell migration,proliferation,differentiation,and sur-vival.In the central nervous system,chemokines and their receptors are involved in immune response and can exert a certain regulatory effect on neuroinflammation.This article reviews the research advances in chemokines and their receptors in cognitive disorders,in or-der to provide new insights and targets for the early diagnosis and treatment of related diseases.

Background The prevalence of hyperuricemia (HUA) among Chinese residents has been increasing annually, with occupational populations facing a higher risk of HUA due to shift work or obesity. Objective To investigate the impact of shift work and obesity on HUA among coal miners, and to provide scientific data for the prevention of HUA in this occupational group. Methods A cross-sectional study was conducted with 25619 workers from a coal mining group in 2023 as the study population, using a questionnaire survey and occupational health check-ups. Workers who were retired or on medical leave, as well as those who provided incomplete responses to the questionnaire or did not complete anthropometric measurements or blood tests, were excluded. A total of 23173 participants were included in the study. An unconditional logistic regression model was used to analyze the association between HUA and selected factors such as shift work status, years of shift work, daily shift work hours, body mass index (BMI), waist-to-height ratio (WHtR), and visceral adiposity index (VAI), as well as the interaction between obesity and shift work on HUA. Restricted cubic spline functions were used to analyze the dose-response relationship between years of shift work, daily shift work hours, and HUA. Results The average age of the included workers was (42.38 ± 9.82) years. A total of 6735 workers reported positive HUA, with a positive rate of 29.1%, and the prevalence was higher in men compared to women (31.8% vs. 13.9%). After adjusting for confounding factors, the restricted cubic spline model revealed a nonlinear dose-response relationship between years of shift work, daily shift work duration, and HUA: ① When the years of shift work exceeded 3.25 years, the risk of HUA in workers gradually increased with longer work duration. At 20 years of shift work, the risk increase showed a "saturation effect," meaning that the risk of HUA no longer increased with additional years of shift work. ② When daily shift work duration was below 10 h, the risk of HUA increased with the length of shift work, but after exceeding 10 h, the risk stabilized. After adjusting for confounding factors, the logistic regression model showed that, compared to non-shift workers, shift workers, those with 10-20 years and over 20 years of shift work experience, as well as those working less than 8 h and more than 8 h per day, had a higher risk of HUA, with odds ratios (OR) of 1.14 (95%CI: 1.06, 1.22), 2.42 (95%CI: 2.20, 2.67), 2.23 (95%CI: 2.00, 2.48), 1.41 (95%CI: 1.29, 1.54), and 1.90 (95%CI: 1.75, 2.06), respectively. Additionally, compared to individuals with normal obesity indices, those with overweight and obesity based on BMI, high and very high VAI and excessive WHtR had a higher risk of HUA, with ORs of 2.01 (95%CI: 1.85, 2.17), 3.51 (95%CI: 3.20, 3.84), 1.42 (95%CI: 1.32, 1.54), 2.10 (95%CI: 1.91, 2.30), and 1.82 (95%CI: 1.69, 1.97), respectively. The interaction analysis showed no interaction between shift work and obesity index (both P_s < 0.001). Conclusion Shift work, longer shift work years, and longer daily shift work hours increase the risk of HUA among coal miners. Additionally, the role of obesity in the development of HUA cannot be ignored.
