Hygroscopicity research has long been a key focus and hot topic in Chinese materia medica（CMM）. Elucidating hygroscopic mechanisms plays a vital role in formulation design， process optimization， and storage condition selection. Hygroscopic models serve as essential tools for characterizing CMM hygroscopic mechanisms， with various types available. The double exponential model is a kinetic mathematical model constructed based on the law of conservation of energy and Fick's first law of diffusion， tailored to the physical properties of CMM extracts. In recent years， this model has been extensively applied to simulate the dynamic moisture absorption behavior of CMM extracts and solid dosage forms under varying humidity conditions. It has revealed the correlation between moisture absorption kinetic parameters and material properties， offering a new perspective for characterizing the moisture uptake behavior of CMM. This paper systematically reviews the application progress of this model in the field of CMM， analyzes its advantages， disadvantages， and challenges in this domain， and explores its potential application trends in other fields. It aims to provide references for elucidating the moisture absorption mechanisms of CMM and researching moisture-proofing technologies， while also offering insights for its broader application in food and polymer materials.

Chronic mucocutaneous candidiasis (CMC) is an infectious phenotype characterized by recurrent or persistent infections caused by Candida species that affect the skin, nails, oral, and genital mucosae for a duration exceeding six months. Current research suggests that CMC is an immunodeficiency disease with a complex pathogenesis. Patients with CMC have various defects in nonspecific and/or specific immunity against Candida infection, resulting in the inability of patients to defend themselves against Candida infection. CMC can be stratified into primary CMC and secondary CMC based on etiology. Primary CMC is often associated with genetic mutations leading to immunodeficiencies in T helper cell 17 and interleukin-17, whereas secondary CMC is frequently linked to factors such as human immunodeficiency virus infection, diabetes mellitus, and immunosuppressive therapy. Primary CMC typically manifests as Candida infections, with distinct genetic mutations often correlating to varied concomitant symptoms. Secondary CMC may present with not only superficial mucosal Candida infections and manifestations of the underlying primary disease but also with invasive fungal infections. Diagnosing CMC requires an integration of medical history and clinical presentation, supplemented by the outcomes of auxiliary diagnostic procedures, including microscopic examination of fungal smear, fungal culture, immunological testing, and genetic sequencing and analysis. Furthermore, confirming primary CMC requires exclusion of the aforementioned secondary factors. At present, antifungal drugs such as triazoles, echinocandins, and polyenes are the main treatment for CMC. Moreover, immunotherapy with biologics such as Janus kinase (JAK) inhibitors provides more options for the clinical treatment of patients with CMC. Gene therapy also has potential clinical application value. In this review, we discuss the etiologies, pathogenesis, clinical manifestations, diagnosis, and treatments of CMC, aiming to provide a reference for the clinical diagnosis and treatment of CMC.

Panax quinquefolium, also known as American ginseng, is a perennial herb in the Araliaceae family. It has the effects of replenishing Qi and nourishing Yin, clearing heat and generating saliva. Additionally, it has protective effects on the nerves, improves myocardial ischemia and hypoxia, regulates metabolism, enhances the body's immunity, and is known as "green gold". However, with the development of the industry and the expansion of planting scales, P. quinquefolium faces serious disease issues that are difficult to prevent and control. Among these, root rot, often referred to as "plant cancer", is one of the most destructive plant diseases affecting the yield and quality of P. quinquefolium. P. quinquefolium root rot is caused by the fungi Fusarium(genus) and Ilyonectria(genus), which severely affect the root system and limit the production and quality of P. quinquefolium, thus restricting the development of the P. quinquefolium industry. In recent years, research on P. quinquefolium root rot has attracted significant attention and made some progress. However, the mechanisms of interaction between the root rot pathogens and the host plant remain unclear. This paper reviews the research progress on the pathogens, infection cycle, disease prevalence, pathogenesis, and biological control of P. quinquefolium root rot to provide prospects for future research, aiming to provide references for the in-depth study and effective control of root rot, and to promote the green and healthy development of the P. quinquefolium industry.

Objective:To explore the clinical application effect of belimumab in the treatment of systemic lupus erythematosus(SLE)and its influence on cluster of differentiation(CD40)and cluster of differentiation 40 ligands(CD40L)expression in the peripheral blood,and to provide a theoretical basis for the effective treatment of SLE.Methods:A retrospective analysis was conducted on the clinical data of 150 patients with SLE admitted to our hospital,and they were divided into conventional treatment group(n=78,standard treatment plan)and belimumab group(n=72,standard treatment plan+belimumab)according to the treatment methods.The therapeutic effects and adverse reactions were compared.The clinical symptoms,organ involvement,disease activities,prednisone doses,the expression levels of CD40 and CD40L mRNA in peripheral blood mononuclear cells,and the levels of immunology-related indicators before and after treatment were analyzed.Results:Compared with conventional treatment group,the total effective rate,complement C3 and complement C4 levels in the belimumab group were significantly increased after treatment(P<0.01 or P<0.001),while the proportion of renal involvement,the SLE disease activity index-2K(SLEDAI-2K)score,the dosage of prednisone,immunoglobulin G(IgG)level and the expression levels of CD40 and CD40L mRNA in peripheral blood mononuclear cells were decreased(P<0.01 or P<0.001).There was no statistically significant difference in the total incidence of adverse reactions between two groups during treatment period(P>0.05).Conclusion:Belimumab can increase the effective rate of SLE treatment,reduce disease activity,decrease the involvement of the kidneys and the dose of hormones,and has good safety;its mechanism of action may be related to down-regulating the expression of CD40 and CD40L in peripheral blood and improving the immune function.

Hospitals presently confront multiple challenges, including rapid technological advancements, escalating healthcare demands, and continuously rising healthcare costs, thereby necessitating the introduction of new quality productive forces to drive high-quality hospital development. Adopting the perspective of new quality productive forces, the authors examined the transformation trend from conventional fragmented medical services towards integrated digital healthcare systems. Through the establishment of digital infrastructure characterized by big data, cloud computing, the Internet of Things, and artificial intelligence, hospitals could realize deep integration between inpatient and outpatient care, as well as seamless online and offline service delivery. Concurrently, oriented by the healthcare needs of residents, a precise and efficient " prevention-diagnosis-treatment-rehabilitation" service mode was proposed. This mode could facilitate the extension of innovation and industrial chains originating from healthcare services, expedite the translation of research outcomes into practice, and promote scientifically meticulous hospital management. Collectively, these measures could enable hospitals to develop patient-centered, comprehensive life-cycle healthcare service systems, thereby promoting the high-quality development of hospitals.

BACKGROUND: T-cell lymphoblastic lymphoma/acute lymphoblastic leukemia (T-LBL/ALL) is an aggressive form of hematological malignancy associated with poor prognosis in adult patients. Histone deacetylases (HDACs) are aberrantly expressed in T-LBL/ALL and are considered potential therapeutic targets. Here, we investigated the antitumor effect of a novel HDAC inhibitor, chidamide, on T-LBL/ALL. METHODS: HDAC1, HDAC2 and HDAC3 levels in T-LBL/ALL cell lines and patient samples were compared with those in normal controls. Flow cytometry, transmission electron microscopy, and lactate dehydrogenase release assays were conducted in Jurkat and MOLT-4 cells to assess apoptosis and pyroptosis. A specific forkhead box O1 (FOXO1) inhibitor was used to rescue pyroptosis and upregulated gasdermin E (GSDME) expression caused by chidamide treatment. The role of the FOXO1 transcription factor was evaluated by dual-luciferase reporter and chromatin immunoprecipitation assays. The efficacy of chidamide in vivo was evaluated in a xenograft mouse. RESULTS: The expression of HDAC1, HDAC2 and HDAC3 was significantly upregulated in T-LBL/ALL. Cell viability was obviously inhibited after chidamide treatment. Pyroptosis, characterized by cell swelling, pore formation on the plasma membrane and lactate dehydrogenase leakage, was identified as a new mechanism of chidamide treatment. Chidamide triggered pyroptosis through caspase 3 activation and GSDME transcriptional upregulation. Chromatin immunoprecipitation assays confirmed that chidamide led to the increased transcription of GSDME through a more relaxed chromatin structure at the promoter and the upregulation of FOXO1 expression. Moreover, we identified the therapeutic effect of chidamide in vivo . CONCLUSIONS This study suggested that chidamide exerts an antitumor effect on T-LBL/ALL and promotes a more inflammatory form of cell death via the FOXO1/GSDME axis, which provides a novel choice of targeted therapy for patients with T-LBL/ALL.

A 59-year-old male patient with sigmoid colon cancer and liver metastasis received the treatments of cetuximab combined with FOLFIRI regimen (irinotecan, calcium folinate, and fluorouracil). His serum creatinine (Scr) was 82 μmol/L, and estimated glomerular filtration rate (eGFR) was 96 ml/(min·1.73 m 2) before the treatment. On the 11th day after finishing the 4th cycle of treatments, the patient developed nausea and vomiting. Laboratory tests showed Scr 221 μmol/L, eGFR 29 ml/(min·1.73 m 2), serum albumin 29.0 g/L, urinary protein (+++), and 24 hour urine protein quantified 8.88 g. He was diagnosed as having nephrotic syndrome complicated with acute kidney injury, which was considered to be related to cetuximab. The drug was stopped and symptomatic treatments such as anti-inflammatory, anticoagulation and kidney protection were given. After 14 days, laboratory tests showed no proteinuria, Scr 156 μmol/L, and eGFR 44 ml/(min·1.73 m 2). Prednisone acetate tablet 50 mg were orally administered once daily. Fifty-nine days later, his Scr was 142 μmol/L, and eGFR was 49 ml/(min·1.73 m 2). Chemotherapy was suspended and cetuximab was discontinued permanently.
