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.

Objective To analyse the clinical efficiency of endolymphatic sac surgery (ESS) in the management of Meniere’s disease (MD). Methods A retrospective analysis was conducted on 274 patients with MD who were hospitalized for treatment in Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University from January 2009 to August 2023. All patients received lifestyle management and drug treatment such as diuretics. For those whose conditions were not well controlled 3 to 6 months after the initial treatment, intratympanic glucocorticoid (ITG) or ESS treatment was carried out. Six months after the treatment, the classes of vertigo relief and hearing changes in the patients were evaluated. After adjusting the confounding factors through propensity score matching (PSM), the impact of ESS on the prognosis of MD patients was evaluated. Results Among 274 patients, 194 and 80 patients underwent ITG and ESS, respectively. Eighty patients were enrolled into each group after PSM. Before and after PSM, the rate of patients reaching vertigo relief class A in ESS group was higher than that in the ITG group (P＝0.004); there was no significant difference in hearing preservation between the two groups. Kaplan-Meier curve analysis showed that vertigo relief in the ESS group was better than that in the ITG group (P=0.029); there was no statistically significant difference in hearing preservation between the two groups. Conclusion When the initial treatment for patients with MD is ineffective, choosing ESS is more beneficial than ITG for controlling vertigo.

Purpose: Neuroendocrine prostate cancer (NEPC) represents a particularly aggressive subtype of prostate cancer with a challenging prognosis. The purpose of this investigation is to craft and confirm the reliability of nomograms that can accurately forecast the 1-, 3-, and 5-year overall survival (OS) and cancer-specific survival (CSS) rates for individuals afflicted with NEPC. Materials and Methods: Data pertaining to patients diagnosed with NEPC within the timeframe of 2010 to 2020 was meticulously gathered and examined from the Surveillance, Epidemiology, and End Results Program (SEER). To predict OS and CSS, we devised and authenticated two distinct nomograms, utilizing predictive variables pinpointed through both univariate and multivariate Cox regression analyses. Results: The study encompassed 393 of NEPC patients, who were systematically divided into training and validation cohorts at a 2:1 ratio. Key prognostic factors were isolated, verified, and integrated into the respective nomograms for OS and CSS. The performance metrics, denoted by C-indices, stood at 0.730, 0.735 for the training set, and 0.784, 0.756 for the validation set. The precision and clinical relevance of the nomograms were further corroborated by the analysis of receiver operating characteristic curves, calibration plots, and decision curve analyses. Conclusions The constructed nomograms have demonstrated impressive efficacy in forecasting the 1-, 3-, and 5-year OS and rates for patients with NEPC. Implementing these predictive tools in clinical settings is anticipated to considerably enhance the care and treatment planning for individuals diagnosed with this aggressive form of prostate cancer, thus providing tailored and more precise prognostic assessments.

Objective:To investigate any effect of aerobic exercise on the functioning of endothelial progenitor cells (EPCs) and on the Akt/eNOS signaling pathway in type 2 diabetes.Methods:Forty-five 6-week-old Sprague-Dawley rats free of specific pathogens were randomly divided into a normal control group, a diabetic model group and an exercise group. Type 2 diabetes mellitus was induced in the model and exercise groups by feeding a high-fat diet and streptozotocin injection. After successful modeling, the exercise group underwent 8 weeks of non-weight-bearing swimming training after which blood was collected from their abdominal aortas to measure EPCs, serum nitric oxide and the level of vascular endothelial growth factor (VEGF). Bone marrow-derived EPCs were isolated from the rats′ femurs and tibias for in vitro culture. The cells′ tube formation capacity was assessed using Matrigel assays, while the expression of protein kinase B (Akt) and endothelial nitric oxide synthase (eNOS) were determined using western blotting.Results:Compared with the normal group, the model group exhibited significantly reduced counts of EPCs in their peripheral blood. Serum NO and VEGF were also significantly lower, on average, and tube formation capacity was significantly impaired. p-Akt and p-eNOS protein expression were significantly downregulated. In contrast, the exercise group showed significantly increased EPC counts, elevated serum NO and VEGF levels, improved tube formation, and upregulated p-Akt and p-eNOS expression compared with the model group.Conclusions:Aerobic exercise improves EPC functioning in diabetic rats, and its mechanism may be associated with the regulation of the Akt/eNOS signaling pathway.

In order to explore the potential of nanoparticles from ethanol extracts of Euphorbia he-lioscopia L.(ZQNPs)in antibacterial application.In this study,ZQNPs were prepared by the self-assembly method using alcohol extract of Euphorbia helioscopia L.,polylysine and polyethylene glycol 1 000 as raw materials.The morphology and structure of ZQNPs were characterized by transmission electron microscopy,UV-vis spectrophotometer,and Fourier transform infrared spec-troscopy.The growth and biofilm inhibition of ZQNPs against methicillin-resistant Staphylococcus aureus(MRSA)were tested by broth microdilution,crystal violet,and checkerboard assays.The broad-spectrum antibacterial activity and antibacterial activity of ZQNPs against three clinical strains were evaluated by broth microdilution method.Finally,the antibacterial mechanism of ZQNPs was preliminarily explored by morphological observation and soluble protein detection of MRSA.The results showed that ZQNPs were self-assembled and cross-linked multi-faceted spheres with an average diameter of 67 nm.The MIC of ZQNPs against MRSA was 8 mg/L,and the antibacterial effect was much better than that of Euphorbia helioscopia L.mongolicum alcohol extract(MIC＞32 mg/L).The time killing curve again showed that ZQNPS had a good antibacteri-al effect on MRSA(8 mg/L)biofilm inhibition rate of 89％,and the antibacterial effect of ZQNPS combined with cefquinome sulfate showed additive results.The mics of ZQNPs against Gram-posi-tive bacteria(S.aureus)and gram-negative bacteria(E.coli)were 16 mg/L and 8 mg/L,respec-tively.The mics of ZQNPS against E.coli clinical strains were stable between 8 and 16 mg/L.The MIC of Salmonella clinical strains was 32-64 mg/L,and the MIC of S.aureus clinical strains was 8-64 mg/L.Preliminary antibacterial mechanism showed that ZQNPs could destroy the membrane structure of MRSA,lead to the release of intracellular substances,and affect the growth of MRSA.These results indicate that ZQNPs have a good antibacterial effect and have potential application value in antimicrobial therapy.
