Esophageal cancer （EC） is a highly prevalent malignant tumor in China. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， as one of the key oncogenic pathways， can promote the cell cycle progression， proliferation， migration， and invasion， induce chemoresistance， and inhibit apoptosis and autophagy of EC cells. Traditional Chinese medicine （TCM）， with the advantages of targeting multiple points with multiple components to delay cancer progression， can target the PI3K/Akt signaling pathway for EC treatment. This article preliminarily discusses the molecular mechanism and role of the PI3K/Akt signaling pathway in EC and elaborates on the specific targets and efficacy of TCM in treating EC through intervention in the PI3K/Akt signaling pathway in the past five years. TCM materials and extracts inhibiting the PI3K/Akt signaling pathway in EC include Borneolum， spore powder of Ganoderma lucidum without spore coat， extract of Celastrus orbiculatus， root extract of Taraxacum， and Bruceae Fructus oil emulsion. TCM active ingredients exerting the effect include flavonoids， terpenoids， saponins， phenols， polysaccharides， alkaloids， and other compounds. TCM compound prescriptions with such effect include Qige San， Huqi San， Xuanfu Daizhetang， Tongyoutang and its decomposed prescriptions， Liujunzi Tang， and Xishenzhi Formula. In addition， TCM injections such as Compound Kushen Injection and Kang'ai injection also inhibit the PI3K/Akt signaling pathway in EC. This paper summarizes the role of the PI3K/Akt signaling pathway in EC and the TCM interventions， aiming to provide reference for the research and clinical application of new drugs for EC.

BACKGROUND: Ferroptosis-related genes play a crucial role in regulating intracellular iron homeostasis and lipid peroxidation, and they are involved in the regulation of tumor growth and drug resistance. The expression of ferroptosis-related genes in tumor tissues can be used to predict patients' future survival times, aiding doctors and patients in anticipating disease progression. Based on the sequencing data of lung adenocarcinoma (LUAD) patients from The Cancer Genome Atlas (TCGA) database, this study identified genes involved in the regulation of ferroptosis, constructed a prognostic model, and evaluated the predictive performance of the model. METHODS: A total of 1467 ferroptosis-related genes were obtained from the GeneCards database. Gene expression profiles and clinical data from 541 LUAD patients were collected from the TCGA database. The expression data of all ferroptosis-related genes were extracted, and differentially expressed genes were identified using R software. Survival analysis was performed on these genes to screen for those with prognostic value. Subsequently, a prognostic risk scoring model for ferroptosis-related genes was constructed using LASSO regression model. Each LUAD patient sample was scored, and the patients were divided into high-risk and low-risk groups based on the median score. Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC) was calculated. Kaplan-Meier survival curves were generated to assess model performance, followed by validation in an external dataset. Finally, univariate and multivariate Cox regression analyses were conducted to evaluate the independent prognostic value and clinical relevance of the model. RESULTS: Through survival analysis, 121 ferroptosis-related genes associated with prognosis were initially identified. Based on this, a LUAD prognostic risk scoring model was constructed using 12 ferroptosis-related genes (ALG3, C1QTNF6, CCT6A, GLS2, KRT6A, LDHA, NUPR1, OGFRP1, PCSK9, TRIM6, IGF2BP1 and MIR31HG). The results indicated that patients in the high-risk group had significantly shorter survival time than those in the low-risk group (P<0.001), and the model demonstrated good predictive performance in both the training set (1-yr AUC=0.721) and the external validation set (1-yr AUC=0.768). Risk scores were significantly associated with the prognosis of LUAD patients in both univariate and multivariate Cox regression analyses (P<0.001), suggesting that this score is an important prognostic factor for LUAD patients. CONCLUSIONS This study successfully established a LUAD risk scoring model composed of 12 ferroptosis-related genes. In the future, this model is expected to be used in conjunction with the tumor-node-metastasis (TNM) staging system for prognostic predictions in LUAD patients.

The disturbance of the human microbiota influences the occurrence and progression of many diseases. Live therapeutic bacteria, with their genetic manipulability, anaerobic tendencies, and immunomodulatory properties, are emerging as promising therapeutic agents. However, their clinical applications face challenges in maintaining activity and achieving precise spatiotemporal release, particularly in the harsh gastrointestinal environment. This review highlights the innovative bacterial functionalized encapsulation strategies developed through advances in physicochemical and biological techniques. We comprehensively review how bacterial encapsulation strategies can be used to provide physical barriers and enhanced adhesion properties to live microorganisms, while introducing superior material properties to live bacteria. In addition, this review outlines how bacterial surface coating can facilitate targeted delivery and precise spatiotemporal release of live bacteria. Furthermore, it elucidates their potential applications for treating different diseases, along with critical perspectives on challenges in clinical translation. This review comprehensively analyzes the connection between functionalized bacterial encapsulation and innovative biomedical applications, providing a theoretical reference for the development of next-generation bacterial therapies.

Guided by molecular networking, nine novel curvularin derivatives (1-9) and 16 known analogs (10-25) were isolated from the hydrothermal vent sediment fungus Penicillium sp. HL-50. Notably, compounds 5-7 represented a hybrid of curvularin and purine. The structures and absolute configurations of compounds 1-9 were elucidated via nuclear magnetic resonance (NMR) spectroscopy, X-ray diffraction, electronic circular dichroism (ECD) calculations, ¹³C NMR calculation, modified Mosher's method, and chemical derivatization. Investigation of anti-inflammatory activities revealed that compounds 7-9, 11, 12, 14, 15, and 18 exhibited significant suppressive effects against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in murine macrophage RAW264.7 cells, with IC₅₀ values ranging from 0.44 to 4.40 μmol·L^-1. Furthermore, these bioactive compounds were found to suppress the expression of inflammation-related proteins, including inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), NLR family pyrin domain-containing protein 3 (NLRP3), and nuclear factor kappa-B (NF-κB). Additional studies demonstrated that the novel compound 7 possessed potent anti-inflammatory activity by inhibiting the transcription of inflammation-related genes, downregulating the expression of inflammation-related proteins, and inhibiting the release of inflammatory cytokines, indicating its potential application in the treatment of inflammatory diseases.

Objective:To evaluate the safety and efficacy of tumor-treating fields (TTFields) and chemoradiation in patients with high-grade glioblastoma.Methods:Clinical data of 38 patients admitted to the Jiangsu Cancer Hospital from September 2021 to May 2023 who were diagnosed with high-grade glioblastoma (36 cases of World Health Organization grade Ⅳ and 2 cases of grade Ⅲ) were retrospectively analyzed. All patients received TTFields combined with concurrent chemoradiation after surgery. Response assessment in neuro-oncology (RANO) criteria was used to evaluate the glioma responses as tumor remission, stable or progression. Common terminology criteria for adverse events v5.0 and TTFields related skin adverse reaction (dAE) criteria were used to evaluate the adverse events. Treatment compliance was assessed by data on the NovoTTF-200A therapeutic device, calculated as a percentage of daily TTFields usage time. Survival analysis was estimated by the Kaplan-Meier method and compared by the log-rank test.Results:The median duration of treatment with TTFields in 38 patients was 20 h (rang: 2.4-22.6 h), and the median treatment compliance was 83% (range: 10%-94%). After 42 days of TTFields combined with concurrent chemoradiation, 12 patients who underwent complete tumor resection were assessed as stable according to RANO criteria. Among the 26 patients who underwent partial tumor resection, 23 (88%) were evaluated as disease remission according to RANO criteria. The 7-, 10-, 13-month progression-free survival rate was 81.0%、64.0%、49.5%, repectively. The common adverse events included grade 1 (45%) and grade 2 (8%) dAE, without grade 3-4 dAE. Typical presentations included contact dermatitis, blisters, lesions or ulcers, and abscesses. The median follow-up time was 10.0 months (range: 1.6-21.3 months). At follow-up as of July 2023, 26 of the 38 patients were stable and 12 had disease progression (8 died).Conclusion:The preliminary results show that TTFields combined with chemoradiation is effective, safe and reliable treatment for high-grade glioblastoma.

A 28-year-old woman was found to have coagulation factor Ⅷ activity (FⅧ∶C) <1% and von Willebrand factor antigen (VWF∶Ag) <1% during routine prenatal examinations. No pathogenic variation was found in the exon region of the VWF gene using next-generation sequencing. The clinical presentation of this patient does not match the clinical characteristics of type Ⅲ hemophilia [von Willebrand disease (VWD) ]; therefore, third-generation sequencing technology was used to perform whole-genome sequencing on the patient and her family members. Multiple members of the patient’s paternal family carried a heterozygous variant of VPS33B, c.869G>C. The family members carrying this variant all had varying degrees of reduced VWF levels (39% -56% ). Moreover, the proband was detected with the heterozygous variant c.1474dupA in GP1BA. The ACMG and Clinvar databases determined that this variation was associated with platelet-type pseudo VWD. The decrease in VWF levels caused by heterozygous variations in VPS33B in families is the first international report, and no previous studies have reported cases of severe decrease in plasma VWF levels caused by double heterozygous variations in VPS33B and GP1BA.

Objective:To investigate the current status of social support, readiness for discharge, and loneliness in elderly patients with diabetes mellitus type 2 (T2DM) and the relationship among them.Methods:A total of 230 elderly T2DM patients treated in the Endocrinology Department of the First Affiliated Hospital of Anhui Medical University from April to October 2022 were selected as research objects by the convenient sampling method. Patients were surveyed using a general information questionnaire, Readiness for Discharge Scale, Perceived Social Support Scale and UCLA Loneliness Scale. The Spearman correlation analysis was used to investigate the correlation between social support, loneliness and discharge readiness in elderly T2DM patients. Model 4 in SPSS Process 4.0 software was used to examine the mediating effects of discharge readiness, social support and loneliness in elderly patients with T2DM. A total of 230 questionnaires were sent out and 222 were effectively received, with effective recovery of 96.5% (222/230) .Results:The total scores of Readiness for Discharge Scale, Perceived Social Support Scale and UCLA Loneliness Scale in 222 elderly T2DM patients were 104.00 (91.00, 113.00), 65.00 (57.50, 72.00) and 36.50 (26.00, 44.25), respectively. Spearman correlation analysis showed that social support was positively correlated with discharge readiness ( r=0.448, P<0.05), and loneliness was negatively correlated with social support and readiness for discharge ( r=-0.563, -0.512, P<0.05). The mediating effect analysis showed that loneliness played a partial mediating role between social support and hospital readiness, with an effect ratio of 42.8%. Conclusions:Clinical medical staff should pay attention to the psychological state of patients, alleviate the loneliness of elderly T2DM patients, improve the level of social support, so as to improve the readiness of patients for discharge and increase the self-management ability of elderly diabetes mellitus type 2 patients after discharge.
