To analyze the occurrence and risk factors of acute kidney injury (AKI) in patients with hematologic malignancies who experienced severe delayed excretion after high-dose methotrexate (HD-MTX) chemotherapy, and to explore dose adjustment strategies for reusing HD-MTX in these patients.
A retrospective analysis was conducted on clinical data of hematologic malignancy patients treated with HD-MTX in the hematology and oncology departments. Patients with severe delayed MTX excretion (defined as serum MTX >30 μmol·L-1 at 24 h, >3 μmol·L-1 at 48 h, >0.3 μmol·L-1 at 72 h, or prolonged low-level MTX >0.3 μmol·L-1 for >6 days) were included. Patients were divided into three groups based on AKI severity, group A was mild AKI, group B was moderate AKT, group C was severe AKI. Statistical methods were used to analyze risk factors for severe excretion delay and AKI.
Among 26 patients (28 HD-MTX cycles) with severe delayed excretion, AKI occurred in all cycles (100.00%). Group A accounted for 21.43% (6 cases/28 cases), Group B accounted for 46.43% (13 cases/28 cases), accounted for 32.14% (9 cases/28 cases). Pre-treatment albumin levels in group A, group B and group C were (42.22±4.63), (39.08±4.3) and (35.25±4.19) g·L-1. Among patients with moderate/severe AKI, 11 received 19 subsequent HD-MTX cycles at reduced doses (1/3-1× original), with no recurrence of excretion delay or AKI.
Low pre-treatment albumin levels, particularly <35 g·L-1 are strongly associated with severe MTX-related AKI. Patients with a history of MTX-induced AKI can safely reuse HD-MTX at adjusted doses (based on renal recovery and clinical indicators) without AKI recurrence.

To develop a transdermal delivery system for tetraphydrocurcumin nanoemulsion-gel (Thc@NE@gel), and to investigate its therapeutic efficacy and mechanism of action in atopic dermatitis (AD).
Thc@NE@gel was prepared using a high-energy emulsification method combined with a low-temperature swelling process. The formulation was characterized for particle size, zeta potential, drug loading, encapsulation efficiency, morphology and physicochemical properties. In vitro transdermal absorption experiments were conducted using a Franz diffusion cell. An AD mouse model was established, and successfully induced mice were randomly divided into animal control group, positive drug group (10mg·kg-1 dexamethasone gel), animal model group, Thc@NE group (Thc@NE 20 mg·kg-1) and animal Thc@NE@gel low-, medium- and high-dose experimental groups (10, 20, and 30 mg·kg-1 Thc@NE@gel), with 6 mice in each group. Body weights of mice in each group were measured and changes recorded; hematoxylin and eosin (HE) staining was performed to observe histopathological damage in skin tissue; enzyme-linked immunosorbent assay (ELISA) was used to detect serum inflammatory cytokine levels. Concurrently, an in vitro inflammatory model was established using human immortalized keratinocytes (HaCaT). Cells were divided into cell control group, cell model group (LPS 1 μg·mL-1), cell low- and high-dose Thc@NE@gel expreimental groups (10 and 30 μM Thc@NE@gel). Reactive oxygen species (ROS) were measured in each group using flow cytometry; serum inflammatory cytokine levels were detected by ELISA; Western blot analysis was performed to detect the expression of key proteins in the cyclic GMP-AMP synthase-stimulator of interferon genes (cGAS-STING) signaling pathway.
Thc@NE@gel was developed with a particle size of (195.30±5.20) nm, a zeta potential of (-24.51±1.45) mV, and a encapsulation efficiency of (72.70±0.67)%. The body weights of mice in the animal Thc@NE@gel low-, medium-, and high-dose treatment groups, the animal blank group, the animal model group, the Thc@NE group, and the positive control (dexamethasone) group on day 17 were (21.50±1.20), (22.30±1.15), (24.00±1.25), (26.20±1.30), (17.30±1.10), (18.20±1.15) and (17.50±1.05) g, respectively; immunoglobulin E(IgE) levels were (40.52±10.23), (32.84±9.65), (30.67±10.12), (21.23±3.45), (53.21±4.12), (56.45±5.89) and (64.32±12.14) ng·mL-1; IL-17 levels were (48.23±8.12), (25.43±4.67), (30.21±9.87), (23.45±5.12), (84.56±12.34), (54.12±5.67), and (47.89±6.78) pg·mL-1; IL-23 levels were (45.67±3.12), (44.23±2.98), (40.12±2.45), (25.34±7.12), (73.45±15.67), (55.23±6.78), and (24.56±1.89) pg·mL-1; when comparing the animal animal model group with the animal blank group, all of the above inflammatory markers showed statistically significant differences (all P<0.05). Compared with the animal model group, the IgE and IL-17 levels in the animal medium- and high-dose groups of Thc@NE@gel, as well as the IL-23 levels in all dose groups, showed statistically significant differences (all P<0.05); the IgE levels in the positive control group showed no statistically significant difference compared with the animal model group (P>0.05). Furthermore, the relative protein expression levels of cGAS in the low-dose and high-dose cell Thc@NE@gel experimental groups, the cell blank group, and the cell model group were 1.15±0.12, 0.82±0.08, 1.00±0, and 1.65±0.18, respectively; the relative protein expression levels of STING were 0.95±0.10, 0.60±0.06, 1.00±0.00, and 1.65±0.15, respectively. Compared with the animal blank group, all of the aforementioned indicators in the cell model group showed statistically significant differences (all P<0.001).
Thc@NE@gel enhances the anti-inflammatory effects of Thc, providing new insights for the development of skin delivery systems for natural active ingredients; furthermore, by inhibiting the cGAS-STING pathway, Thc@NE@gel improves atopic dermatitis, offering a new mechanistic perspective for its treatment.
To establish a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for determining the plasma concentration of the active component polymyxin E in patients treated with colistimethate sodium.
Polymyxin B1 was used as an internal standard, and solid phase extraction (SPE) was employed to process the samples. The chromatographic column was a Kinetex C18 (3 mm×100 mm, 2.6 μm). Mobile phase A was an aqueous solution containing 0.1% formic acid and 5 mmol·L-1 ammonium acetate, and mobile phase B was a methanol solution containing 0.1% formic acid. Gradient elution was performed at a flow rate of 0.5 mL·min-1. An electrospray ionization (ESI) source was used with positive ion multiple reaction monitoring (MRM) for detection. The ion pairs for quantitative analysis were as follows: m/z 585.6→241.1 (polymyxin E1), m/z 578.6→227.2 (polymyxin E2), and m/z 602.6→101.2 (polymyxin B1). The selectivity, standard curve, residues, precision and accuracy, extraction recovery rate, matrix effect and stability of the method were investigated, and the plasma concentrations of polymyxin E1 and E2 in patients treated with colistimethate sodium were measured.
The linear relationships of polymyxin E1 and E2 concentrations were good within the ranges of 0.02–3.86 μg·mL-1 and 0.03–5.65 μg·mL-1, respectively. The lower limits of quantification (LLOQ) for polymyxin E1 and E2 were 0.02 μg·mL-1 and 0.03 μg·mL-1, respectively. The standard curve equations for polymyxin E1 and E2 are Y=4.55×10-1X-2.92×10-2 (r=0.994 2)、Y=8.61×10-1X-1.38×10-2 (r=0.996 4), respectively. The within-day and day-to-day precision, accuracy, extraction recovery, matrix effects, and stability of polymyxin E1 and E2 all met the methodological requirements. Using this method, the AUC of polymyxin E in 26 patients receiving colistimethate sodium ranged from 28.42 to 317.51 μg·mL-1.
This method is accurate, sensitive, rapid, and stable, and can be used for the determination of the plasma concentrations of polymyxin E1 and E2 in human plasma.
To investigate the etiological factors and clinical characteristics of statin-associated myopathy in elderly patients.
A retrospective analysis was performed on elderly patients with statina-ssociated myopathy who were treated in the internal medicine department of our hospital from January 2017 to June 2024. Data including etiology, clinical manifestations, treatment process and prognosis were collected and analyzed.
A total of 21 elderly patients with statina-ssociated myopathy were enrolled, including 13 males and 8 females, with an average age of (77.33±9.61) years. Among them, 5 patients were diagnosed with rhabdomyolysis. According to the type of statin taken, patients were divided into 5 groups: atorvastatin group, rosuvastatin group, simvastatin group, pitavastatin group and Xuezhikang group. All patients received monotherapy without overlapping or combined use of different statins. The duration of statin therapy at onset ranged from 2 weeks to 10 years. Precipitating factors included infection, concomitant medications, stress and exercise. Among them, 12 cases were related to infection (9 pneumonia, 2 urinary tract infections, 1 intestinal infection), and 2 cases were associated with concomitant medications (quetiapine and cyclosporine A, respectively). Most patients had multiple comorbidities: hypertension in 90.48% (19 cases/21 cases), type 2 diabetes mellitus in 66.67% (14 cases/21 cases), coronary heart disease in 47.62% (10 cases/21 cases), and chronic kidney disease in 23.81% (5 cases/21 cases). Patients were on multiple concomitant medications, with a mean of 6 drugs used. Acute kidney injury occurred in 4 patients with myopathy and in 5 patients with rhabdomyolysis. After comprehensive treatment including statin discontinuation, fluid replacement, urine alkalinization and blood purification, all patients improved and no deaths occurred. Serum creatinine in patients with acute kidney injury returned to normal or baseline levels before onset.
Elderly patients with acute infection, concomitant medications and multiple comorbidities should be closely monitored for the risk of statinassociated myopathy or rhabdomyolysis. Acute kidney injury is common in such elderly patients. Early discontinuation of statins and comprehensive treatment including symptomatic fluid infusion and blood purification can significantly improve patient prognosis.
To analyze the role mechanism of xuesaitong injection (lyophilized) in the treatment of cerebral infarction by network pharmacology and molecular docking technology.
The intersection targets of five important active ingredients (Ginsenoside Rg1, Ginsenoside Rb1, Ginsenoside Re, Notoginsenoside R1, Ginsenoside Rd) in xuesaitong injection (lyophilized) and acute cerebral infarction were screened by database, and the target action network was constructed. Gene ontology (GO) pathway analysis and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis were performed by using digital-audio-video internet devince (DAVID) database, and molecular docking verification was performed.
A total of 61 non-redundant targets were screened for Panax notoginseng saponins, and 5 737 non-redundant targets were identified for cerebral infarction. The intersection of three databases yielded 64 common targets. After intersecting the drug targets with the disease targets, two overlapping targets were obtained: protein kinase C beta (PRKCB) and tumor necrosis factor (TNF). Intersection with the non-redundant disease targets yielded 51 overlapping targets. Based on network topology parameters and the intersection target results, caspase-3 (CASP3), TNF, nuclear factor kappa B subunit 1 (NFKB1), matrix metalloproteinase-9 (MMP9), tumor protein p53 (TP53), and PRKCB were selected for subsequent molecular docking. The results of GO functional enrichment analysis showed that in terms of biological processes, the target genes were mainly involved in the positive regulation of gene expression, the negative regulation of apoptosis process, and the positive regulation of miRNA transcription. In terms of cell components, the target genes were mainly located in extracellular space, extracellular region, blood, axon and protein complex. In terms of molecular function, the target proteins mainly had the same protein binding, protease binding, Heat shock protein 90 (HSP90) protein binding and other functions, and the enrichment results were statistically significant (all P<0.05). The results of KEGG enrichment analysis revealed that the potential targets of xuesaitong injection (lyophilized) in the treatment of cerebral infarction were enriched in advanced glycation end products-receptor for advanced glycation end products (AGE-RAGE) signaling pathway, lipid and atherosclerosis, fluid shear stress and atherosclerosis, proteoglycans in cancer, MAPK signaling pathway, thyroid hormone signaling pathway, apoptosis pathway and other signaling pathways, and the enrichment results were statistically significant (P<0.05). The results of molecular docking displayed that the main active ingredients of xuesaitong injection (lyophilized) had good binding ability with the core target protein, among which Ginsenoside Rg1 had the lowest binding energy with TNF, and CASP3, PRKCB showed strong binding with various active ingredients.
Xuesaitong injection (lyophilized) may play a multi-target comprehensive role in the treatment of cerebral infarction by regulating CASP3, TNF, NFKB1, MMP9, TP53, PRKCB and other key targets, acting on pathways such as apoptosis, inflammation and atherosclerosis.
To systematically elucidate the mechanism of action of Qizhi hypoglycemic tablets (QZT) in treating diabetic vascular complications, this study adopted the methods of network pharmacology and molecular docking.
Active ingredients and their corresponding targets of QZT were retrieved from traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP) and other databases. Disease targets related to diabetic nephropathy, retinopathy, and peripheral neuropathy were collected from The human gene database (GeneCards) and online mendelian inheritance in man (OMIM). Overlapping targets between drugs and diseases were identified, and a protein-protein interaction (PPI) network was constructed. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses were performed using the database for annotation, visualization, and integrated discovery (DAVID). Molecular docking was used to validate the binding interactions between key active components and core targets.
A total of 116 active ingredients, 2 245 disease-related targets, and 354 common targets were obtained. Core targets such as proto-oncogene tyrosine-protein kinase (SRC), signal transducer and activator of transcription 3 (STAT3), estrogen receptor 1 (ESR1), and RAC-alpha serine/threonine-protein kinase (AKT1) were identified. GO and KEGG analyses revealed that the therapeutic effects of QZT were primarily mediated through key pathways including phosphatidylinositol 3-kinase/Akt signaling pathway (PI3K-Akt) and advanced glycation end products-receptor for advanced glycation end products signaling pathway (AGE-RAGE). Molecular docking confirmed stable binding of core components including apigenin, baicalein, and 4′,7-dihydroxyflavanone (DFV) to the core targets.
This study preliminarily clarifies the multi-component, multi-target, and multi-pathway mechanism of QZT against diabetic vascular complications, providing a theoretical basis for its clinical application and further investigation.

There was no statistically significant difference in the levels of lactate dehydrogenase (LDH) and cardiac troponin Ⅰ (cTnⅠ) of L-carnitine compared with the control group (all P>0.05).
The effectiveness of levocarnitine in the treatment of myocardial damage is relatively good, and there are no obvious adverse reactions.
Gastrointestinal tumors, as clinically prevalent and highly malignant cancers, are closely associated with oxidative stress in their development. By inducing imbalances in intracellular reactive oxygen species (ROS) levels, oxidative stress promotes tumor cell proliferation, invasion, and drug resistance, making it a key target in contemporary cancer prevention and treatment research. In recent years, individual components of traditional Chinese medicine (TCM) have demonstrated significant potential in regulating oxidative stress due to their well-defined structures, diverse actions, and multi-target regulatory properties. This systematic review summarizes recent advances in how various TCM monomeric components inhibit gastrointestinal tumor cell proliferation and migration, induce apoptosis, and modulate the tumor microenvironment through antioxidant mechanisms. It focuses on analyzing key signaling pathways and molecular targets involved, such as nuclear factor E2-related factor 2 (Nrf2), mitogen-activated protein kinase (MAPK), and nuclear factor kappa-B (NF-κB). Integrating existing experimental evidence and partial clinical data, this review further reveals the potential application value of TCM monomers in the prevention and treatment of gastrointestinal tumors, while identifying current research challenges. It aims to provide theoretical foundations and directional references for basic research and new drug development in this field.
Osteoporosis (OP) is a severe skeletal system disease that endangers human physical and mental health, characterized primarily by decreased bone mineral density, impaired bone tissue quality, disrupted bone microstructure and reduced bone mechanical strength. The pathogenesis of OP involves multiple aspects, including impaired communication between osteoblasts and osteoclasts, dysregulated bone remodeling homeostasis, as well as angiogenesis disorders, chronic inflammatory responses and oxidative stress damage. Notably, the correlation between angiogenesis and osteogenesis exists throughout bone formation, the development and progression of OP, and fracture healing, serving as a key link in the regulation of bone metabolism. In recent years, traditional Chinese medicine (TCM) has demonstrated remarkable advantages and definite curative effects in the prevention and treatment of OP. Commonly used Chinese medicinal monomer in clinical practice can promote the proliferation and differentiation of osteoblasts through multiple pathways and targets, enhance the angiogenic capacity of osteogenic tissue, improve blood supply to bone tissue, and thereby increase bone mineral density, which is of great significance for the prevention and treatment of OP. This paper systematically reviews the recent research progress on Chinese medicinal monomer in the treatment of OP, aiming to explore new diagnostic and therapeutic ideas and practical approaches for the prevention and treatment of this disease with TCM.
Bone is not a static scaffold but a highly dynamic organ, whose development and homeostasis are significantly influenced by various drugs and xenobiotics. While traditional research has primarily focused on nutritional, hormonal, and genetic factors affecting bone, growing evidence highlights drugs and xenobiotics exposure as critical, non-negligible risk factors for bone health. This review systematically summarizes and analyzes the pharmacological impact of drugs (such as aromatase inhibitors, tyrosine kinase inhibitors, insulin sensitizers and antibiotics) and xenobiotics (such as heavy metals, environmental pollutants and endocrine disruptors) on bone development and metabolism. It emphasizes their roles in disrupting bone metabolic balance—through mechanisms including interference with signaling pathways, induction of oxidative stress, mimicry or antagonism of endocrine hormones, triggering of chronic inflammation, and induction of epigenetic alterations—leading to impaired bone microstructure, reduced bone strength, and increased fracture risk. Additionally, this review compiles potential bone-protective drugs and exogenous nutrients, evaluating their pharmacological actions in promoting bone health via supplemental osteogenic substrates, modulation of osteoblast/osteoclast activity, and repair of bone metabolic damage. The aim of this synthesis is to provide a pharmacological foundation for assessing risks posed by drugs and related xenobiotics to bone development and to offer new perspectives for preventing and treating bone-related disorders.
Messenger ribonucleic acid (mRNA) vaccines represent a relatively new vaccine technology and have currently been applied to vaccine development across multiple infectious disease areas. To ensure the safety of participants, the safety evaluation of mRNA vaccines remains a key focus in current vaccine clinical research. This article discusses the safety assessment of preventive mRNA vaccines, drawing on clinical safety data and evaluations from currently marketed vaccines.
To provide practical references for all participants in drug clinical trials on drug safety risk management and promote the construction of a more efficient clinical trial safety management system.
Based on the regulatory practice of 40 clinical trial safety risk control cases from the Center for Drug Evaluation in 2024, this paper uses classified statistics and correlation analysis methods to analyze the characteristics of safety risk information from multiple dimensions such as drug types and indications, and systematically sorts out the response logic of regulatory measures.
Among the 40 cases where risk management procedures were initiated, distinct risk characteristics were observed across different drug types and indications. The regulatory measures reflected the principle of matching the intensity of control with the risk characteristics.
Regulatory authorities have adopted differentiated regulatory requirements in accordance with the logic of risk classification and bottom-line thinking. The regulatory initiatives have gradually evolved into focusing on the optimization and full-chain improvement of sponsors’ risk management systems, providing crucial support for the protection of subjects’ rights and interests as well as the high-quality development of pharmaceutical innovation..

IITs registered in the Medical Research Registration and Filing Information System by the hospital from January 2020 to April 2025 were selected as the research objects. The research compliance, scientificity, and value were assessed, and then followed by statistical analysis.
Among the 124 IITs, 76% were initiated by investigators with associate senior titles or above. The median scores of the standardization and scientificity dimensions were both 8 points, while the median score of the research value dimension was 6 points. The total scores of interventional studies and observational studies were 23 and 21, respectively (P<0.01), and the total scores of multi-center studies and single-center studies were 23 and 20, respectively (P<0.001). Except for the correlation between funding support and the scientificity score, which the difference was not statistially signifccant (P>0.05), funding support showed a significant positive correlation with both the research compliance and research value dimensions (correlation coefficients ranging from 0.300 to 0.346, all P<0.001); disciplinary strength, and investigator title were significantly positively correlated with all three dimensions of research quality (correlation coefficients ranging from 0.213 to 0.380, P<0.01, P<0.001) and disciplinary strength had the greatest impact on research value.
Medical institutions still need to strengthen the standardization and scientificity of IITs, and there is great room for improvement in research value. Disciplinary strength, investigator background, and funding support are key factors affecting the research quality. From the perspective of institutional management, the quality of IITs can be effectively improved by constructing a systematical management system that integrates scientific review, methodological support and resource guarantee.
