Secondary organizing pneumonia after infection is a pathological condition characterized by connective tissue filling and obstructing the alveoli and bronchioles, in which following an infection in the lung, the inflammatory response is not controlled in a timely and effective manner. The pathogenesis and treatment of this condition can be interpreted through the Sanjiao membranous tube theory and the concept of stagnation within the pulmonary micro-membrane. Sanjiao is conceptualized as a four-way membranous tube that internally connects with the zangfu organs and externally with the skin and muscles, enabling the circulation of energy and fluids throughout the body. It also maintains communication with the zangfu micro-membranes. Within the lungs, the pulmonary micro-membrane is distributed and connected to the upper jiao membranous tube, facilitating the movement of qi and fluids and supporting nutrient distribution. External pathogens may invade the Sanjiao membranous system through the external membranous tube, travel internally along this system, and transform into latent pathogens that settle within the pulmonary micro-membrane. These latent pathogens can subsequently transform into heat or dampness, leading to the depletion of lung qi and impairing the lung′s ability to regulate and transport body fluids. Consequently, fluids may seep into the pulmonary micro-membrane, where they are transformed into dampness, turbidity, and phlegm. The accumulation of damp-turbidity and phlegm obstructs the flow of qi and blood, resulting in blood stasis in the pulmonary collaterals. This stagnation occurring within both the pulmonary micro-membrane and its associated collaterals underlies the development of secondary organizing pneumonia after infection. In severe cases, this condition may progress to pulmonary interstitial fibrosis. The therapeutic approach emphasizes expelling latent pathogens, regulating and dredging the pulmonary micro-membrane, tonifying the healthy qi, and supporting health. Regulating and dredging the pulmonary micro-membrane is a crucial step, with a focus on promoting the flow of lung qi, resolving dampness and phlegm, and activating blood circulation to remove stasis.

The vasculature plays a critical role in homeostasis and health as well as in the development and progression of a wide range of diseases, including cancer, cardiovascular diseases, metabolic diseases (and their complications), chronic inflammatory diseases, ophthalmic diseases, and neurodegenerative diseases. As such, the growth of the vasculature mediates normal development and physiology, as well as disease, when pathologically induced vessels are morphologically and functionally altered owing to an imbalance of angiogenesis-stimulating and angiogenesis-inhibiting factors. This review offers an overview of the angiogenic process and discusses recent findings that provide additional interesting nuances to this process, including the roles of intussusception and angiovasculogenesis, which may hold promise for future therapeutic interventions. In addition, we review the methodology, including those of in vitro and in vivo assays, which has helped build the vast amount of knowledge on angiogenesis available today and identify important remaining knowledge gaps that should be bridged through future research.

Ulcerative colitis (UC) is a chronic inflammatory disorder with a complex etiology, characterized by intestinal inflammation and barrier dysfunction. Platycodon grandiflorus polysaccharides (PGP), the primary component of Platycodon grandiflorus, and hesperidin (Hesp), a prominent active component in Citrus aurantium L. (CAL), have both demonstrated anti-inflammatory properties. This study aims to elucidate the underlying mechanism of the synergistic effect of PGP combined with Hesp on UC, focusing on the coordinated interaction between the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) and Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathways. A mouse model of UC induced by dextran sulfate sodium (DSS) and a cell model using lipopolysaccharide (LPS)-induced RAW264.7/IEC6 cells were employed to investigate the in vitro and in vivo anti-inflammatory effects of PGP combined with Hesp on UC and its potential mechanism of action. The results indicated that compared to the effects of either drug alone, the combination of PGP and Hesp significantly modulated inflammatory factor levels, inhibited oxidative stress, regulated colonic mucosal immunity, suppressed apoptosis, and restored intestinal barrier function in vitro and in vivo. Further in vitro studies revealed that PGP significantly inhibited the PI3K/AKT signaling pathway, while Hesp significantly inhibited the JAK2/STAT3 signaling pathway. The use of inhibitors and activators targeting both pathways validated the synergistic effects of PGP combined with Hesp on the PI3K/AKT and JAK2/STAT3 signaling pathways. These findings suggest that PGP combined with Hesp exhibits a synergistic effect on DSS-induced colitis, potentially mediated through the phosphatase and tensin homolog (PTEN)/PI3K/AKT and interleukin-6 (IL-6)/JAK2/STAT3 signaling pathways.

Objective To analyze the characteristics of real-world adverse drug events(ADEs)of trabectedin based on the FDA Adverse Event Reporting System(FAERS)database in order to provide references for clinical drug safety management.Methods A total of 1 349 trabectedin-related reports were extracted from the FAERS database from Q1 2007 to Q4 2024.Using the MedDRA coding classification system for system organ class(SOC)and preferred term(PT),signal detection was performed through 4 proportional imbalance methods,including reporting odds ratio(ROR)and proportional reporting ratio(PRR).Subgroup analyses by gender,age,and temporal trends were also conducted.Results Hematological and lymphatic system disorders and hepatobiliary system disorders were the primary SOCs involved.High-frequency PTs included neutropenia(123 cases)and anemia(117 cases).Eight potential ADEs that have not been listed in the drug product instruction were identified.The median onset time of ADEs was 21 d,showing an early failure pattern,with differences observed by gender(females more prone to hematological toxicity)and age(elderly more susceptible to febrile neutropenia).Conclusion Trabectedin requires close attention to hematological toxicity,hepatotoxicity,and newly identified multi-system potential risks.Clinically,monitoring should be strengthened based on time windows and population characteristics to optimize drug regimens.Countermeasure It is recommended to strengthen the full cycle monitoring of anti-tumor drugs,standardize the reporting of adverse reactions,and establish a multi-departmental collaborative research platform.

Abstract: Inflammatory bowel disease (IBD), whose pathogenesis remains elusive, is a group of autoimmune diseases characterized by chronic, progressive, and lifelong inflammation of the digestive tract. The pathogenesis of IBD remains elusive. Although a number of drugs have been developed to treat IBD, their effects are merely anti-inflammatory. In addition, current treatments for IBD are easily susceptible to resistance in clinical practice. Mesenchymal stem cells (MSCs) have been reported to have the ability to migrate to the site of inflammation, with potent immunoregulatory effects, and to rebalance the immune microenvironment and restore the integrity of the epithelial barrier with significant value of application, particularly for patients who are refractory to classic medicines. In this paper, we reviewed the clinical applications, mechanisms and engineerable properties of MSC products and their exosomes to provide some reference for the use of MSCs and their exosomes in the treatment of IBD.

Objective:To understand the basic information such as age,job title,and education of rehabilita-tion therapists in the Grade Ⅲ public psychiatric hospitals in China,and provide fundamental data for the construc-tion of the mental health rehabilitation talent team.Methods:The staffing of rehabilitation therapists in 43 Grade Ⅲpublic psychiatric hospitals in eastern,central,and western regions of China were investigated.The age,education,job title,professional relevance and inter-regional differences of the rehabilitation therapists were statistically ana-lyzed.Results:There were 197 rehabilitation therapists in 43 hospitals surveyed.The age distribution was mainly in 20-30 and 30-40 years old with a bachelor's degree and junior,and more than half of the personnel had their first academy degree related to the rehabilitation profession.The differences in age,education,job title were statistically significant in the eastern,central and western regions.Conclusion:The overall quality of the rehabilitation therapists in China's Grade Ⅲ public psychiatric hospitals is relatively high,and the age structure is reasonable.However,the proportion of senior professional titles is relatively low.Therefore,it is necessary to focus on talent training and the establishment of promotion systems in the future,in order to improve the professional development space and level of the entire industry.

Objective To investigate the antioxidant activity of bamboo stem extracts and the therapeutic effect of bamboo stem water extract on oxidative inflammation induced by tert butyl hydroperoxide (t-BHP) in human colon adenocarcinoma cells (Caco-2). Methods In this study, ABTS, DPPH, and FRAP assays were used to determine the extracellular antioxidant activity of petroleum ether extract, ethyl acetate extract, n-butanol extract, 95% ethanol extract, and distilled water extract from bamboo stems. The human intestinal Caco-2 cell line was used as the model cell, and t-BHP was selected as the oxidative stress modeling agent. The CCK-8 assay was used to detect cell viability and the optimal oxidative damage concentration of t-BHP. The content of MDA, 8-OHdG, TNF-α and IL-1β were detected to assess antioxidant stress effect. Results The five extracts of bamboo all had certain antioxidant activity, among which the water extract of bamboo stem had the best comprehensive antioxidant activity with high cell viability in Caco-2 cells. The optimal modeling concentration of t-BHP was 200 μMol/L. The water extract of bamboo stem significantly reduced the content of oxidative stress related biomarkers and inflammatory factors in Caco-2 cells induced by t-BHP. Conclusion The stem extracts of bamboo in Xianning City have strong in vitro antioxidant activity. Among them, the water extract of bamboo stem has a protective effect on t-BHP induced oxidative damage in Caco-2 cells, suggesting that the water extract possesses a potential to be developed as new antioxidant products for clinical prevention and treatment of oxidative damage related diseases.

Objective To explore the factors that affect the coordinated development of blood banks and apheresis plas-ma collection banks(hereinafter referred to as plasma banks),and explore feasible measures for the coordinated develop-ment of blood banks and plasma banks.Methods The blood information management system and blood source information management system were used to retrieve related data of blood and plasma donation from 9 cities in Shandong province from 2017 to 2021.The number of blood donors and plasma donors and the intersection of them were analyzed.The data analysis was performed using chi-square test,and a questionnaire survey was conducted to investigate the policies and information status,as well as expectations for coordinated development for blood and plasma donation.Results From 2017 to 2021,the total number of blood donors in 9 cities was higher than that of plasma donors,both have been increasing year by year,and the increase in plasma donors was significantly higher than that of blood donors(131.78%vs 23.90%,P<0.05).The inter-section proportion of blood and plasma donors had increased from 0.45%in 2017 to 1.04%in 2021,with an increase of 131.11%.Among the administrative regions where the participating blood and plasma banks located,94.2%have not re-leased relevant policy to promote the coordinated development of blood and plasma donation.The majority(63%)expected blood banks and plasma banks to be set at a distance more than 50 km apart.The top four functional requirements for the in-terconnection between blood banks and plasma banks management information system were blood test results(94.61%),ID number(87.54%),blood and plasma donation records(85.51%)and health consultation/examination results(82.15%).The top four elements of coordinated development between blood and plasma banks were policy support(96.25%),informa-tion networking(92.36%),top-level design(87.44%)and cultural construction(86.58%).Conclusion The number of donors who donate both blood(mainly whole blood)and plasma has been increasing year by year,which deserves our close attention.To achieve the coordinated development of blood donation and plasma donation,policy support is the most crucial and fundamental means.Establishment of a standard system and the share of blood and plasma donation information is neces-sary for blood informatization construction.It was critical to promote the coordinated development of blood and plasma dona-tion and ensure blood safety with improving legislation,formulating policies for coordinated development,strengthening top-level design,standardizing the publicity of blood and plasma donation and establishing the idea that blood and plasma dona-tion are equally honorable.

Objective This study aims to investigate the primary target and potential mechanism of mangiferin(MF)in treating oral submucous fibrosis(OSF)through Gene Expression Omnibus(GEO)database chip mining,network pharmacology,and molecular docking techniques.Methods Potential therapeutic targets for OSF were identified using GEO chip data.The potential targets of MF were predicted,and disease-related targets for OSF were col-lected from databases.A Venn diagram was created using the EVenn platform to identify overlapping targets.The protein-protein interaction(PPI)network was constructed using the STRING database.Gene ontology(GO)and Kyoto Encyclope-dia of Genes and Genomes(KEGG)enrichment analyses were performed using the DAVID platform.Cytoscape 3.10.1 software was used to visualize a drug-target-pathway-disease network,while AutoDocktools 1.5.6 software was employed for molecular docking analysis.Results A total of 356 potential targets for MF and 360 disease-related targets for OSF were obtained from multiple databases.The top 15 key target proteins in the PPI network were selected as significant candi-dates.GO function and KEGG pathway enrichment analyses revealed that MF treatment primarily involved advanced gly-cation end products-receptor(AGE-RAGE),epidermal growth factor receptor(EGFR),and other signaling pathways associ-ated with OSF pathogenesis.Molecular docking analysis demonstrated that MF exhibited a strong binding activity toward AKT serine kinase 1(AKT1),tumor necrosis factor(TNF),and other core targets.Conclusion These findings suggest that MF may exert its therapeutic effects on OSF through a multitarget approach involving various signaling pathways.

Renal interstitial fibrosis（RIF） is the main pathological manifestation of chronic kidney disease. Due to the complexity of the mechanism， there is no specific treatment for RIF in clinical practice. The abnormal activation of the phosphatidylinositol 3-kinase （PI3K）/protein kinase B（Akt） signaling pathway and the activation of downstream target genes are key drivers of RIF induction and progression. Traditional Chinese medicine has the characteristics of precise efficacy and minimal toxic side effects， and the occurrence and development of RIF can be regulated by multiple targets and mutual coordination. This review focuses on the PI3K/Akt signaling pathway and summarizes the potential targets and regulatory mechanisms of traditional Chinese medicine in the treatment of RIF. It is found that various effective ingredients （such as sinomenine， mangiferin， coumarin derivates from Hydrangea paniculata， etc.） and formulas （such as Fushengong decoction， Qi-Bang-Yi-Shen formula， etc.） of traditional Chinese medicine can inhibit fibroblast proliferation， improve inflammation and oxidative stress， maintain mitochondrial stability， and slow down ferroptosis through this pathway， thereby delaying the occurrence and progression of RIF.
