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.

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 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.

OBJECTIVE To investigate the effects and mechanism of Yiqi huoxue decoction （YQHX） on lumbar disc herniation in rats. METHODS Rats were randomly divided into sham operation group， model group， NF-κB inhibitor group （QNZ group， 1 mg/kg）， YQHX group （9.1 g/kg） and combination group （YQHX+QNZ group， the same dose as each single drug group）， with 10 rats in each group. Except for sham operation group， lumbar disc herniation model of rats was induced in other groups； administration groups were given QNZ intraperitoneally or/and YQHX intragastrically， once a day， for 8 consecutive weeks. The severity of intervertebral disc herniation was evaluated in each group； the pathological changes of intervertebral discs and the changes of autophagy of nucleus pulposus cells were all observed； the level of tumor necrosis factor-α （TNF-α） in serum， and the ratios of Bcl-2/adenovirus E1B interacting protein 3 （BNIP3） and Beclin-1 positive cells in intervertebral disctissues were detected； the phosphorylation of nuclear factor-κB （NF-κB） p65， the expressions of tumor necrosis factor receptor- associated factor-2 （TRAF-2）， TRAF-3， BNIP3 and LC3B protein， and mRNA expressions of NF-κB p65， LC3B， p62，BNIP3 and Beclin-1 were determined. RESULTS Compared with model group， Pfirrmann grading score decreased significantly，the pathological injury of intervertebral disc tissue was relieved in YQHX group； the number of autophagosomes in nucleus pulposus cells increased； serum level of TNF-α and mRNA expression of p62 in intervertebral disc tissue decreased significantly； the ratios of BNIP3 and Beclin-1 positive cells， the phosphorylation of NF-κB p65， the expressions of TRAF-2， TRAF-3， BNIP3 and LC3B protein as well as the mRNA expressions of NF- κB p65， LC3B， BNIP3 and Beclin-1 decreased significantly in intervertebral disc tissues （P＜0.05）. The changes of above indexes in YQHX group were reversed partly in YQHX+QNZ group. CONCLUSIONS YQHX promotes the elevation of autophagy level of intervertebral discs， slows down the inflammatory response and the progression of lumbar disc herniation by activating the NF-κB signaling pathway.

BACKGROUND: In China, lung cancer remains the cancer with the highest incidence and mortality rate. Among early-stage lung adenocarcinomas (LUAD), the micropapillary (MPP) component is prevalent and typically exhibits high aggressiveness, significantly correlating with early metastasis, lymphatic infiltration, and reduced five-year survival rates. Therefore, the study is to explore the similarities and differences between MPP and non-micropapillary (non-MPP) components in malignant pulmonary nodules characterized by GGOs in early-stage LUAD, identify unique mutational features of the MPP component and analyze the relationship between the ZNF469 gene, a member of the zinc-finger protein family, and the prognosis of early-stage LUAD, as well as its correlation with immune infiltration. METHODS: A total of 31 malignant pulmonary nodules of LUAD were collected and dissected into paired MPP and non-MPP components using microdissection. Whole-exome sequencing (WES) was performed on the components of early-stage malignant pulmonary nodules. Mutational signatures analysis was conducted using R packages such as maftools, Nonnegative Matrix Factorization (NMF), and Sigminer to unveil the genomic mutational characteristics unique to MPP components in invasive LUAD compared to other tumor tissues. Furthermore, we explored the expression of the ZNF469 gene in LUAD using The Cancer Genome Atlas (TCGA) database to investigate its potential association with the prognosis. We also investigated gene interaction networks and signaling pathways related to ZNF469 in LUAD using the GeneMANIA database and conducted Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Lastly, we analyzed the correlation between ZNF469 gene expression and levels of immune cell infiltration in LUAD using the TIMER and TISIDB databases. RESULTS: MPP components exhibited a higher number of genomic variations, particularly the 13th COSMIC (Catalogue of Somatic Mutations in Cancer) mutational signature characterized by the activity of the cytidine deaminase APOBEC family, which was unique to MPP components compared to non-MPP components in tumor tissues. This suggests the potential involvement of APOBEC in the progression of MPP components in early-stage LUAD. Additionally, MPP samples with high similarity to APOBEC signature displayed a higher tumor mutational burden (TMB), indicating that these patients may be more likely to benefit from immunotherapy. The expression of ZNF469 was significantly upregulated in LUAD compared to normal tissue, and was associated with poor prognosis in LUAD patients (P<0.05). Gene interaction network analysis and GO/KEGG enrichment analysis revealed that COL6A1, COL1A1, COL1A2, TGFB2, MMP2, COL8A2 and C2CD4C interacted with ZNF469 and were mainly involved in encoding collagen proteins and participating in the constitution of extracellular matrix. ZNF469 expression was positively correlated with immune cell infiltration in LUAD (P<0.05). CONCLUSIONS The study has unveiled distinctive mutational signatures in the MPP components of early-stage invasive LUAD in the Asian population. Furthermore, we have identified that the elevated expression of mutated ZNF469 impacts the prognosis and immune infiltration in LUAD, suggesting its potential as a diagnostic and prognostic biomarker in LUAD.

Objective:To explore the factors affecting changes of disc angle (ΔDA) during oblique lateral interbody fusion (OLIF) and establish a predictive model of ΔDA.Methods:This retrospective study included 119 patients with 174 segments undergoing OLIF procedures between July 2017 and August 2019 in Beijing Jishuitan Hospital. 45 males and 74 females with an average age of 62.1±9.8 years (33-86 years) were included. The lordotic cages were all 6 degrees. Radiographic parameters included preoperative and postoperative disc angle (DA), disc height (DH), ΔDA on flexion-extension views (ΔDA-FE), cage location and cage inclination. Pearson correlation coefficient and machine-learning techniques were utilized to identify factors related to ΔDA. Based on machine leaning techniques, ten-fold cross-validation for model training and validation were used to develop a predictive linear model for ΔDA.Results:The average ΔDA was 3.9°±4.8° with preoperative disc angle (preoperative DA) of 5.3°±5.0°. The average change of posterior DH (ΔPDH) was 3.1±2.1 mm with preoperative posterior DH of 6.6±1.9 mm. The average change of anterior DH was 6.1±3.2 mm. Pearson correlation analysis showed a significant negative correlation between ΔDA and preoperative DA ( r=-0.713, P<0.001), cage location ( r=-0.183, P=0.016), and ΔDA-FE ( r=-0.153, P=0.044). PDH changes were significantly negatively correlated with preoperative PDH ( r=-0.444, P<0.001) and positively correlated with cage location ( r=0.218, P=0.004). ΔDA was 10.8°±3.2° for negative preoperative DA (indicating kyphotic), 5.0°±3.7° for preoperative DA between 0° and 6°, and 1.0°±4.1° for preoperative DA>6°. A predictive model was developed using ten-fold cross-validation, resulting in the formula ΔDA=7.9°-0.8×preoperative DA ( R=0.707, MAE=2.837). Conclusion:Disc angle changes in OLIF primarily depend on the preoperative disc angle, secondly on cage location. The predicting model based on machine-learning techniques using preoperative disc angle facilitates preoperative planning for OLIF procedures.
