OBJECTIVE To evaluate the cost-effectiveness of cefiderocol versus best available therapy (BAT) or standard-of- care (SOC) for the treatment of confirmed or suspected carbapenem-resistant Gram-negative bacterial (CRGNB) serious infections from the perspective of the Chinese healthcare system, and to explore its reasonable pricing. METHODS A decision tree model was constructed based on data from two phase Ⅲ clinical trials (CREDIBLE-CR and GAME CHANGER) to simulate the cost- effectiveness of cefiderocol in two scenarios: salvage therapy for confirmed CRGNB infection (scenario 1) and empirical therapy for suspected CRGNB infection (scenario 2). The primary outcome measure was the incremental cost-effectiveness ratio (ICER). The willingness-to-pay (WTP) was set at 1 to 3 times China’s per capita GDP in 2024. To verify the robustness of the results, one- way and probabilistic sensitivity analyses were conducted, and based on these, a reasonable price range for cefiderocol in the Chinese market was explored. RESULTS The results for scenario 1 showed that the clinical cure rate in the cefiderocol group was higher than that in the BAT group (47.50% vs. 34.21%), but its ICER was 415 065.03 yuan per cured case, exceeding three times China’s GDP per capita. Scenario 2 revealed that the ICER for cefiderocol relative to SOC was as high as 1 362 446.16 yuan per cured case, far exceeding the WTP. Sensitivity analysis indicated that the treatment duration and price of cefiderocol were key factors affecting its cost-effectiveness. In the two scenarios described above, the unit price of cefiderocol must fall below 683.47 and 242.00 yuan/g, respectively, to be considered cost-effective. CONCLUSIONS Based on the current market price, cefiderocol lacks sufficient cost-effectiveness for treating confirmed or suspected CRGNB serious infections within China’s healthcare system. To improve its accessibility, price negotiations or a tiered medical insurance payment strategy are required.

ObjectiveTo observe the clinical efficacy of the Yiqi Yangyin Huoxue prescription (YYHP) in the treatment of cathartic colon (CC) and its effects on fecal short-chain fatty acids (SCFAs), and to explore the correlations among CC severity indicators and between these indicators and patient history. MethodsAccording to the inclusion and exclusion criteria, 98 patients meeting the diagnostic criteria of both traditional Chinese and Western medicine for CC with the syndrome of Qi-Yin deficiency complicated by blood stasis were randomly assigned to an observation group and a control group. The observation group received YYHP granules, while the control group received lactulose. Both medications were administered twice daily, one sachet each time, half an hour after breakfast and dinner, with a treatment course of 8 weeks. The primary constipation symptom score, Patient Assessment of Constipation Quality of Life (PAC-QOL) score, and TCM syndrome score were assessed before and after treatment and at the 8th week after the end of treatment. The overall clinical effective rate, as well as the efficacy attenuation index and degree, were evaluated. Fecal SCFA levels were measured using gas chromatography-mass spectrometry (GC-MS). Spearman correlation analysis was performed to explore the correlations among CC severity indicators and between these indicators and patient history. ResultsThe overall clinical effective rate in the observation group (95.83%) was higher than that in the control group (78.72%) (P<0.05). After treatment, the total scores for primary constipation symptoms, PAC-QOL, and TCM syndromes decreased in both groups (P<0.05), with more significant reductions in the observation group (P<0.05). The severity of all primary constipation symptoms was alleviated in both groups (P<0.05). In terms of "excessive straining and difficult defecation", "anal heaviness, incomplete evacuation, and bloating sensation", "abdominal distension", and "defecation frequency", the observation group showed better efficacy than the control group (P<0.05). Scores of the four PAC-QOL dimensions and the scores and severity of primary and secondary TCM symptoms were reduced in both groups (P<0.05), with more significant reductions in the observation group (P<0.05). After treatment, acetic acid, propionic acid, butyric acid, and total SCFAs in the observation group increased significantly (P<0.05). The efficacy attenuation index and degree in the observation group were lower than those in the control group (P<0.05). No severe adverse reactions occurred in either group, and there was no statistically significant difference in the incidence of adverse reactions between the two groups. Positive correlations of varying degrees were observed among the total scores of primary constipation symptoms, PAC-QOL, and TCM syndromes, as well as between these scores and the history of stimulant laxative use, disease duration, and age. ConclusionYYHP can effectively alleviate the primary constipation symptoms in CC patients, improve quality of life, and ameliorate TCM syndromes, with good safety. It also has the advantage of a lower rebound degree after drug withdrawal, and its mechanism may be related to increasing fecal SCFA levels. Long-term abuse of stimulant laxatives may aggravate the severity of CC and prolong the disease course.

ObjectiveTo evaluate and analyze the syndrome characteristics of Qi and Yin deficiency accompanied by Qi stagnation and blood stasis in a rhein-induced cathartic colon (CC) rat model. MethodsTwenty-four rats were divided into a normal group and a model group (CC group). The rats were administered equal volumes of physiological saline or 2% rhein suspension by gavage to establish the model over three cycles (approximately 118 days). The first cycle lasted 46 days, with a dosage of 12 mL·kg-1·d-1, administered every other day. The second cycle lasted 37 days, with a dosage of 12 mL·kg-1·d-1, administered for 5 consecutive days followed by 2 days of cessation. The third cycle lasted 35 days, with a dosage of 16 mL·kg-1·d-1, also administered for 5 consecutive days followed by 2 days of cessation. Each cycle ended when 80% of the rats no longer exhibited loose stools. Body mass, 24 h food intake, coat condition, and coat red (R), green (G), and blue (B) values were recorded. The open field test (OFT) was used to measure the total distance traveled to evaluate Qi deficiency. The body mass coefficient and 24 h water intake were recorded to assess Yin deficiency. The sucrose preference test (SPT) was used to determine the sucrose preference rate (SPR), and the average speed in OFT was measured to evaluate depressive status (liver depression and Qi stagnation). Tongue images and their R, G, and B values were recorded. Whole blood viscosity (WBV) and plasma viscosity (PV) were measured using an automatic hemorheological analyzer to evaluate blood stasis. A carbon ink propulsion test was performed to determine the intestinal transit rate (ITR) for disease model evaluation. Hematoxylin-eosin (HE) staining was used to observe histopathological changes in the colon. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of transient receptor potential ankyrin 1 (TRPA1) and tryptophan hydroxylase 1 (TPH1) in colon tissue. Western blot was used to detect the protein expression of TRPA1 and TPH1. ResultsIn terms of syndrome indicators, compared with the normal group, the body mass of the CC group decreased (P<0.05), while 24 h food intake increased (P<0.01). The coats of the CC group appeared withered, disheveled, and dull, and the R, G, and B values of the coat decreased (P<0.01). The total distance traveled in OFT decreased (P<0.01). The body mass coefficient decreased (P<0.01), while 24 h water intake increased (P<0.05, P<0.01). The SPR decreased (P<0.01), and the average speed in OFT slowed (P<0.01). The tongue appeared dark red, and the R, G, and B values of tongue images decreased (P<0.01). WBV and PV increased (P<0.01). Regarding disease indicators, compared with the normal group, the ITR decreased in the CC group (P<0.01). Pathologically, HE staining showed necrosis and shedding of colonic mucosal epithelial cells, disruption of mucosal continuity, and infiltration of inflammatory cells in the lamina propria in the CC group. Semi-quantitative analysis showed increased HAI scores (P<0.05) and increased inflammatory cell counts and area proportion (P<0.05). In terms of molecular biological indicators, compared with the normal group, the mRNA and protein expression levels of TRPA1 and TPH1 in colon tissue decreased in the CC group (P<0.05, P<0.01). ConclusionThe rhein-induced CC rat model conforms to the traditional Chinese medicine syndrome characteristics of Qi and Yin deficiency accompanied by Qi stagnation and blood stasis.

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.

ObjectiveTo establish a mouse model of particulate matter 2.5 (PM2.5)-induced dry eye and investigate whether Chufeng Yisuntang can ameliorate the PM2.5-induced ocular surface damage by regulating the reactive oxygen species (ROS)/p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. MethodsSixty 8-week-old male C57BL/6J mice were used. Ten were randomly selected as the control group. The remaining 50 mice received topical instillation of 1 drop (0.1 mL) of 5 g·L-1 PM2.5 suspension in both eyes, four times daily. Successfully modeled mice were randomized into four groups (n=10): Model, p38 MAPK inhibitor, Chufeng Yisuntang, and combination (Chufeng Yisuntang at 7.3 g·kg-1 + p38 MAPK inhibitor SB203580 at 5 mg·kg-1). Chufeng Yisuntang was administered via gavage, and the inhibitor group via intraperitoneal injection. The control and model groups received equal volumes of distilled water by gavage. All treatments lasted for 4 weeks. General conditions were dynamically observed. Tear secretion, tear film break-up time, and corneal fluorescein staining were assessed. After intervention for 4 weeks, hematoxylin and eosin (HE) staining was used to examine the histopathological changes. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure serum levels of ROS, malondialdehyde (MDA), superoxide dismutase (SOD) 1, and SOD2. Western blot and Real-time PCR were employed to determine the protein and gene levels, respectively, of p38 MAPK, B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), and cysteinyl aspartate-specific proteinase-3 (Caspase-3) in the corneal tissue. ResultsCompared with the control group, the model group exhibited reduced tear secretion volume and tear film breakup time, along with increased corneal fluorescein staining scores (P<0.01). Compared with the model group, the Chufeng Yisuntang group, p38 MAPK inhibitor group, and combination group demonstrated increased tear secretion volume and tear film breakup time, along with decreased corneal fluorescein staining scores (P<0.01). HE staining revealed that compared with the control group, the model group exhibited marked increases in corneal epithelial cell layers and epithelial thickness, along with reduced meibomian gland acini and intensely stained, densely packed nuclei around the acini. Compared with the model group, the Chufeng Yisuntang group, p38 MAPK inhibitor group, and combination group showed intact corneal structure, improved cell morphology, and reduced damage severity. ELISA revealed elevated ROS and MDA levels (P<0.01) and decreased SOD1 and SOD2 levels (P<0.01) in the model group compared with the control group. Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination lowered ROS and MDA levels (P<0.01), while raising SOD1 and SOD2 levels (P<0.05, P<0.01). Western blot revealed that compared with the control group, the model group exhibited increased protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01) and reduced protein level of Bcl-2 (P<0.01). Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination down-regulated the protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), while up-regulating the protein level of Bcl-2 (P<0.01). Compared with the Chufeng Yisuntang group, the combination group exhibited decreased protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01) and increased protein level of Bcl-2 (P<0.01). Real-time PCR revealed that compared with the control group, the model group exhibited upregulated mRNA levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), and downregulated mRNA level of Bcl-2 (P<0.01). Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination down-regulated the mRNA levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), while up-regulating the mRNA level of Bcl-2 (P<0.05, P<0.01). Compared with the Chufeng Yisuntang group, the combination group exhibited decreased mRNA levels of p38 MAPK, Bax, and Caspase-3 expression (P<0.05, P<0.01) and increased mRNA level of Bcl-2 (P<0.01). ConclusionChufeng Yisuntang may partially protect against PM2.5-induced corneal injury by inhibiting the ROS/p38 MAPK pathway, enhancing antioxidant defense, and reducing epithelial apoptosis.

ObjectiveThis paper aims to investigate the role of NDC80 kinetochore complex component (NUF2) and magnesium homeostasis in ovarian cancer cell apoptosis, as well as the regulatory mechanism of gypenoside L (Gyp-L) on NUF2 and magnesium homeostasis. MethodsOvarian cancer OVCAR3 cells were divided into a blank control group, a low-concentration Gyp-L group (50 µmol·L-1), a high-concentration Gyp-L group (100 µmol·L-1), and a cisplatin (15 µmol·L-1) group. The migration, proliferation, and apoptosis capabilities of OVCAR3 cells were evaluated through cell scratch assays, clonal experiments, and terminal-deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay (TUNEL) staining. Differentially expressed genes of ovarian cancer were screened by using the Gene Expression Omnibus (GEO) database. The interaction relationships of differentially expressed genes and proteins were analyzed via the Search Tool for Recurring Instances of Neighbouring Genes (STRING) database. The prognostic survival analysis was performed by using the Tumor Immune Estimation Resource (TIMER) database, and the differential expression levels of genes were validated with the Gene Expression Profiling Interactive Analysis (GEPIA) database. The mRNA expression levels of NUF2, magnesium homeostasis-related indicators, such as magnesium transporter 1 (MAGT1), non-imprinted in Prader-Willi/Angelman syndrome 1 (NIPA1), NIPA-like domain containing 1 (NIPAL1), as well as apoptosis-related indicators B cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax) in OVCAR3 cells, were detected by real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of NUF2, MAGT1, NIPA1, NIPAL1, Bcl-2, and Bax in OVCAR3 cells were quantitatively analyzed by ProteinSimple WES. A model of overexpression of NUF2 was constructed, and Gyp-L intervention was performed. The molecular mechanism by which Gyp-L induces ovarian cancer cell apoptosis by regulating NUF2 and influencing magnesium homeostasis was quantitatively analyzed and detected through cell cloning, TUNEL staining, Real-time PCR, and ProteinSimple WES. Finally, the Mg2+ content and protein synthesis efficiency were detected by immunofluorescence. ResultsGyp-L significantly inhibited the migration and proliferation capabilities of OVCAR3 cells and promoted their apoptosis (P<0.05). Overexpression of NUF2 markedly increased the expression levels of MAGT1, NIPA1, NIPAL1, and Bcl-2, while reducing the expression level of Bax (P<0.05). It also significantly elevated intracellular Mg2+ content and protein synthesis efficiency and simultaneously inhibited apoptosis (P<0.05). Gyp-L could reverse the magnesium homeostasis imbalance and apoptosis inhibition caused by the overexpression of NUF2, downregulating the expression levels of NUF2, MAGT1, NIPA1, NIPAL1, and Bcl-2 (P<0.05), while upregulating the expression level of Bax (P<0.05). ConclusionGyp-L can inhibit the occurrence of ovarian cancer, and its mechanism may involve inhibiting the expression of NUF2 to maintain magnesium homeostasis and inducing apoptosis of ovarian cancer cells.

ObjectiveTraditional Chinese medicine (TCM) constitutes a valuable cultural heritage and an important source of antitumor compounds. Poria (Poria cocos (Schw.) Wolf), the dried sclerotium of a polyporaceae fungus, was first documented in Shennong’s Classic of Materia Medica and has been used therapeutically and dietarily in China for millennia. Traditionally recognized for its diuretic, spleen-tonifying, and sedative properties, modern pharmacological studies confirm that Poria exhibits antioxidant, anti-inflammatory, antibacterial, and antitumor activities. Pachymic acid (PA; a triterpenoid with the chemical structure 3β-acetyloxy-16α-hydroxy-lanosta-8,24(31)-dien-21-oic acid), isolated from Poria, is a principal bioactive constituent. Emerging evidence indicates PA exerts antitumor effects through multiple mechanisms, though these remain incompletely characterized. Neuroblastoma (NB), a highly malignant pediatric extracranial solid tumor accounting for 15% of childhood cancer deaths, urgently requires safer therapeutics due to the limitations of current treatments. Although PA shows multi-mechanistic antitumor potential, its efficacy against NB remains uncharacterized. This study systematically investigated the potential molecular targets and mechanisms underlying the anti-NB effects of PA by integrating network pharmacology-based target prediction with experimental validation of multi-target interactions through molecular docking, dynamic simulations, and in vitro assays, aimed to establish a novel perspective on PA’s antitumor activity and explore its potential clinical implications for NB treatment by integrating computational predictions with biological assays. MethodsThis study employed network pharmacology to identify potential targets of PA in NB, followed by validation using molecular docking, molecular dynamics (MD) simulations, MM/PBSA free energy analysis, RT-qPCR and Western blot experiments. Network pharmacology analysis included target screening via TCMSP, GeneCards, DisGeNET, SwissTargetPrediction, SuperPred, and PharmMapper. Subsequently, potential targets were predicted by intersecting the results from these databases via Venn analysis. Following target prediction, topological analysis was performed to identify key targets using Cytoscape software. Molecular docking was conducted using AutoDock Vina, with the binding pocket defined based on crystal structures. MD simulations were performed for 100 ns using GROMACS, and RMSD, RMSF, SASA, and hydrogen bonding dynamics were analyzed. MM/PBSA calculations were carried out to estimate the binding free energy of each protein-ligand complex. In vitro validation included RT-qPCR and Western blot, with GAPDH used as an internal control. ResultsThe CCK-8 assay demonstrated a concentration-dependent inhibitory effect of PA on NB cell viability. GO analysis suggested that the anti-NB activity of PA might involve cellular response to chemical stress, vesicle lumen, and protein tyrosine kinase activity. KEGG pathway enrichment analysis suggested that the anti-NB activity of PA might involve the PI3K/AKT, MAPK, and Ras signaling pathways. Molecular docking and MD simulations revealed stable binding interactions between PA and the core target proteins AKT1, EGFR, SRC, and HSP90AA1. RT-qPCR and Western blot analyses further confirmed that PA treatment significantly decreased the mRNA and protein expression of AKT1, EGFR, and SRC while increasing the HSP90AA1 mRNA and protein levels. ConclusionIt was suggested that PA may exert its anti-NB effects by inhibiting AKT1, EGFR, and SRC expression, potentially modulating the PI3K/AKT signaling pathway. These findings provide crucial evidence supporting PA’s development as a therapeutic candidate for NB.

OBJECTIVE To optimize the salt-processing technology for Anemarrhena asphodeloides. METHODS Taking soaking time, stir-frying temperature, and stir-frying time as factors, Box-Behnken response surface methodology was employed to optimize the salt-processing technology of A. asphodeloides using the contents of mangiferin, neomangiferin, isomangiferin, timosaponin BⅡ, timosaponin AⅢ, timosaponin BⅢ, total flavonoids, and total saponins as evaluation indicators. The entropy weight method was applied to determine the weight of each indicator and calculate the comprehensive score. Based on the 17 sets of Box-Behnken response surface methodology results, a genetic algorithm (GA)-back propagation (BP) neural network was used to further optimize the salt-processing technology, with soaking time, stir-frying temperature, and stir-frying time as input layers and the comprehensive score as the output layer. The salt-processing parameters obtained from the two methods were validated and compared to determine the optimal salt-processing technology for A. asphodeloides. RESULTS The optimal salt-processing conditions obtained via the Box-Behnken response surface methodology were as follows: soaking time of 23 min, stir-frying temperature of 160 ℃ , and stir-frying time of 12 min, yielding a comprehensive score of 63.370 2. The GA-BP neural network optimization resulted in the following conditions: soaking time of 24 min, stir-frying temperature of 163 ℃, and stir-frying time of 12 min, with a comprehensive score of 65.163 8. The GA-BP neural network optimization outperformed the results obtained by Box-Behnken response surface methodology. CONCLUSIONS This study successfully optimized the salt-processing technology for A. asphodeloides. Specifically, the technology involves adding 15 mL of 0.1 g/mL saline solution to 50 g of the herbal slices, allowing them to moisten for 24 minutes, and then stir-frying at 163 ℃ for 12 minutes.

Objective:
To evaluate the effects of a multidisciplinary weight management intervention, so as to provide a reference for the formulation of overweight and obesity intervention measures.
Methods:
From April to September 2025, overweight and obese residents aged 18-60 years who participated in a weight loss competition at the Health Management Center of Beilun People's Hospital in Ningbo City were selected as study subjects. They were divided into a control group and an intervention group. The control group received conventional weight management, while the intervention group received the multidisciplinary integrated weight management in addition to the conventional weight management, for a total intervention period of 8 weeks. Weight, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, fasting blood glucose (FBG), triglycerides (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and blood pressure were collected before and after the intervention through physical examinations and laboratory tests. The generalized estimating equations (GEE) method was employed to analyze the differences in indicators between the two groups before and after the intervention.
Results:
The control group comprised 241 participants, including 161 females (66.80%), with a mean age of (35.66±7.80) years. The intervention group consisted of 127 participants, including 86 females (67.72%), with a mean age of (36.80±7.05) years. No statistically significant differences were observed between the two groups at baseline in terms of age, gender, weight, BMI, or waist-to-hip ratio (all P>0.05). Results from the GEE analysis indicated significant interactions between group and time for weight, BMI, waist circumference, and hip circumference (all P<0.05) with greater reductions in these parameters observed in the intervention group compared to the control group before and after the intervention. Similarly, significant interactions between group and time were observed for FBG, TG, TC, and LDL-C (all P<0.05), with the intervention group demonstrating larger decreases in these markers compared to the control group. However, no statistically significant interactions between group and time were observed for waist-to-hip ratio, HDL-C, systolic blood pressure, and diastolic blood pressure (all P>0.05). Following the intervention, a weight loss exceeding 10% was achieved by 13 participants (5.39%) in the control group and 62 participants (48.82%) in the intervention group. The proportion of individuals with a weight loss exceeding 10% was significantly higher in the intervention group compared to the control group (P<0.05).
Conclusion
Compared to conventional weight management, multidisciplinary integrated weight management demonstrated greater efficacy in improving weight-related indicators and blood glucose, blood lipids, and enhancing weight loss outcomes among overweight and obese residents.
