Objective To establish an individualized nomogram model and evaluate its efficacy to provide a possible evaluation basis for the prognosis of lower third and abdominal part of oesophageal adenocarcinoma (EAC). Methods Lower third and abdominal part of EAC patients from 2010 to 2015 were chosen from the SEER Research Plus Database (17 Regs, 2022nov sub). The patients were randomly allocated to the training cohort and the internal validation cohort with a ratio of 7∶3 using bootstrap resampling. The Cox proportional hazards regression analysis was used to determine significant contributors to overall survival (OS) in EAC patients, which would be elected to construct the nomogram prediction model. C-index, calibration curve and receiver operating characteristic (ROC) curve were performed to evaluate its efficacy. Finally, the efficacy to evaluate the OS of EAC patients was compared between the nomogram prediction model and TNM staging system. Results In total, 3945 patients with lower third and abdominal part of EAC were enrolled, including 3475 males and 470 females with a median age of 65 (57-72) years. The 2761 patients were allocated to the training cohort and the remaining 1184 patients to the internal validation cohort. In the training and the internal validation cohorts, the C-index of the nomogram model was 0.705 and 0.713, respectively. Meanwhile, the calibration curve also suggested that the nomogram model had a strong capability of predicting 1-, 3-, and 5-year OS rates of EAC patients. The nomogram also had a higher efficacy than the TNM staging system in predicting 1-, 3-, and 5-year OS rates of EAC patients. Conclusion This nomogram prediction model has a high efficiency for predicting OS in the patients with lower third and abdominal part of EAC, which is higher than that of the current TNM staging system.

Methods: This retrospective study analyzed 32 consecutive IDS patients who underwent UEDD surgery. Clinical features, laboratory data (erythrocyte sedimentation rate and C-reactive protein), and treatment outcomes were analyzed. Results: Definite microorganisms were identified in 27 patients (84.3%), with 24 (88.9%) meeting cure criteria. The cure rate was significantly higher in the detected pathogen group compared to the undetected pathogen group (88.9% vs. 80%; χ²=19.36, p<0.0001). Metagenomic next generation sequencing (mNGS) provided faster diagnosis (41.72±6.81 hours) compared to tissue culture (95.74±35.47 hours, p<0.05). The predominant causative pathogen was Mycobacterium tuberculosis, followed by Staphylococcus aureus. Significant improvements were observed in Visual Analog Scale pain scores, from a mean of 7.9 preoperatively to 1.06 at 1 year postoperatively. The Oswestry Disability Index revealed a similar trend, showing significant improvement (p<0.05). Conclusions UEDD is a viable alternative to traditional open surgery for managing IDS in high-risk patients. UEDD offers a dual therapeutic-diagnostic advantage during the initial admission phase, enabling simultaneous debridement, neurological decompression, and targeted biopsy in a single intervention. Compared with traditional tissue culture, mNGS enables rapid microbiological diagnosis and extensive pathogen coverage.

AIM: To identify the primary active components and underlying mechanisms of Yijing Decoction(YJD)in treating early diabetic retinopathy(DR)based on liquid chromatography-mass spectrometry and network pharmacology.METHODS: Active components of YJD were characterized through LC-MS. Components with optimal ADME(absorption, distribution, metabolism, excretion)properties were selected as key bioactive candidates. Network pharmacology approaches were employed to predict YJD-DR therapeutic targets. Protein-protein interaction(PPI)networks, gene ontology(GO)enrichment analysis, and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analysis were subsequently conducted to predict core targets and networks. Critical targets and pathways were experimentally validated through Western blot.RESULTS: Ten core therapeutic targets were identified, including TNF, Alb, EGFR, STAT3, PTGS2, ESR1, PPAR, MMP9, TLR4, and MAPK. YJD was related to cancer-related signaling, fluid shear stress and atherosclerosis, and neurodegenerative diseases, encompassing key biological processes such as inflammatory response regulation, programmed cell death activation, and enhanced cell migration. Furthermore, Western blot analysis confirmed that YJD significantly inhibited high glucose-induced phosphorylation of STAT3(P-STAT3/STAT3)and ERK(P-ERK/ERK)in rat retinal microvascular endothelial cells.CONCLUSION: This study revealed YJD's pharmacodynamical basis and its multi-component, multi-target, and multi-paths pharmacology. YJD exerts therapeutic effects on DR by coordinately regulating critical signaling pathways and alleviating intraocular inflammation, thus preserving retinal vascular endothelial cells, maintaining blood-retinal barrier integrity, and facilitating retinal neurovascular repair.

Objective: To summarize the long-term efficacy and safety of sacral neuromodulation (SNM) in treating refractory interstitial cystitis/bladder pain syndrome (IC/BPS)，so as to provide clinical evidence for this therapeutic approach. Methods: This study retrospectively analyzed the data of 27 patients with refractory IC/BPS treated at our hospital during Jan.2015 and Dec.2021.All patients underwent SNM Ⅱ.The therapeutic effects were evaluated with Global Response Assessment (GRA).The preoperative and postoperative daily urinary frequency，nocturia frequency，functional bladder capacity，O'Leary-Sant score，pelvic pain，urgency and frequency (PUF) score，quality of life (QoL) score，and visual analogue scale (VAS) score were compared. Results: During the follow-up of (55.55±16.33) months，12 patients showed no symptom relief (GRA≤4)，while 15 experienced symptom relief (GRA>4)，resulting in an efficacy rate of 55.56% (15/27).The average daily urination frequency decreased from (28.74±13.84) to (24.74±16.33) times,the O'Leary-Sant score decreased from (30.19±5.35) to (25.63±9.34)，PUF score decreased from (25.63±5.34) to (22.04±8.29)，QoL score decreased from (5.67±0.55) to (4.33±1.57)，and VAS score decreased from (8.04±1.91) to (5.33±3.09)，the differences were statistically significant (P<0.05). No complications such as incision infections or pain at the implant site were observed. Conclusion: SNM is safe and effective for refractory IC/BPS，but there is a risk of long-term failure.Therefore，patients should be discreetly selected.

Objective To evaluate the value of postoperative radiotherapy (PORT) in patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy. Methods Patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy were chosen from the SEER Research Plus Database [17 Registries, November 2012 Submission (2000-2019)]. The patients were divided into a PORT group and a non-PORT group according to whether the PORT was used. To balance baseline characteristics between non-PORT and PORT groups, R software was used to conduct a propensity score matching (PSM) with a ratio of 1 : 1 and a matching tolerance of 0.01. Both the Cox regression analysis and Kaplan-Meier survival analysis were conducted to evaluate the value of PORT in terms of overall survival (OS) and disease-specific survival (DSS). Results In total, 2468 patients with stage ⅢA-N2 non-small cell lung cancer were enrolled, including 1078 males and 1390 females with a median age of 65 (58-71) years. There were 1336 patients in the PORT group, and 1132 patients in the non-PORT group. Cox regression analysis showed that PORT was not significantly associated with OS (multivariate analysis: HR=1.051, 95%CI 0.949-1.164, P=0.338) and DSS (multivariate analysis: HR=1.094, 95%CI 0.976-1.225, P=0.123). No statistical difference was found in the OS or DSS between non-PORT group and PORT group after PSM analysis (P＞0.05). Conclusion PORT does not have a survival benefit for patients with stage ⅢA-N2 non-small cell lung cancer who received complete resection and chemotherapy.

The WRKYs are a group of plant-specific transcription factors that play important roles in defense responses. In this study, we silenced 2 GmWRKY33B homologous genes using a bean pod mosaic virus (BPMV) vector carrying a single fragment from the conserved region of the GmWRKY33B genes. Silencing GmWRKY33B did not result in morphological changes. However, significantly reduced resistances to Pseudomonas syringae pv. glycinea (Psg) and soybean mosaic virus (SMV) were observed in the GmWRKY33B-silenced plants, indicating a positive role of the GmWRKY33B genes in disease resistance. Kinase assay showed that silencing the GmWRKY33B genes significantly reduced the activation of GmMPK6, but not GmMPK3, in response to flg22 treatment. Reverse transcriptase PCR (RT-PCR) analysis of the genes encoding prenyltransferases (PTs), which are the key enzymes in the biosynthesis of glyceollin, showed that the Psg-induced expression of these genes was significantly reduced in the GmWRKY33B-silenced plants compared with the BPMV-0 empty vector plants, which correlated with the presence of the W-boxes in the promoter regions of these genes. Taken together, our results suggest that GmWRKY33Bs are involved in soybean immunity through regulating the activation of the kinase activity of GmMPK6 as well as through regulating the expression of the key genes encoding the biosynthesis of glyceollins.

ObjectiveThis study aims to investigate the inhibitory effect of Wutoutang on pannus formation in adjuvant-induced arthritis （AIA） rats with wind-cold-dampness Bi syndrome and its potential mechanism. MethodA total of 40 male SD specific pathogen-free （SPF） rats were selected and divided into blank group， wind-cold-dampness Bi syndrome group ［Complete Freund's Adjuvant （CFA）， 200 μg］， Wutoutang group （15 g·kg^-1·d^-1）， and indometacin group （10 mg·kg^-1） according to random number table method. Except for the blank group， the other groups were given wind-cold-dampness stimulation before the CFA injection. After the rats were administered for 30 days， the basic conditions， onset time， arthritis index score， and foot swelling volume of AIA rats with wind-cold-dampness Bi syndrome were observed. Finally， peripheral arterial blood， ankle joint， and synovial tissue were taken. Enzyme-linked immunosorbent assay （ELISA） was used to detect serum hypoxia-inducible factor-1α （HIF-1α）， vascular endothelial growth factor A （VEGFA） protein content， and rheumatism， including anti-O （ASO）， C-reactive protein （CRP）， and rheumatoid factor （RF）. Hematoxylin-eosin （HE） staining revealed the changes in joint histomorphology. Immunohistochemistry was used to detect the expression of HIF-1α and VEGFA， two important proteins in the ankle pathway. Quantitative real-time polymerase chain reaction （Real-time PCR） was used to reveal mRNA levels of HIF-1α， VEGFA， angiopoietin-1 （Ang-1）， and angiopoietin-2 （Ang-2） in rat synovial tissue. ResultThe foot swelling volume and arthritis score of AIA rats with wind-cold-dampness Bi syndrome were substantially higher （P<0.01） compared with the blank group. Serum CRP， RF， and ASO levels were considerably elevated （P<0.01）. HE staining showed obvious hyperplasia of ankle synovium and synovial inflammation， angiogenesis and pannus formation， and aggravated bone destruction， indicating successful modeling. After the intervention of Wutoutang， the onset time was delayed （P<0.01）. Foot swelling volume and arthritis score were decreased （P<0.01）. Serum CRP， RF， and ASO levels were significantly decreased （P<0.01）. The inflammatory hyperplasia of synovial tissue， angiogenesis and pannus formation， and bone destruction were alleviated. The mRNA levels of HIF-1α， VEGFA， Ang-1， and Ang-2 in the synovial membrane were significantly decreased （P<0.05， P<0.01）. The expressions of HIF-1α and VEGFA in serum and ankle joints were decreased （P<0.01）. In the indomethacin group， the onset time of the disease was delayed （P<0.01）. Foot swelling volume and arthritis score were decreased （P<0.01）. Serum CRP， RF， and ASO levels were significantly decreased （P<0.01）. HIF-1α/VEGFA/Ang signaling pathway was activated， and pathological tissue injury was improved. ConclusionWutoutang can delay the onset time of AIA rats with wind-cold-dampness Bi syndrome， reduce foot swelling volume， arthritis score， rheumatic activity， and improve joint histopathology. It can inhibit pannus formation， and its mechanism may be related to down-regulating the expression of the HIF-1α/VEGFA/Ang pathway.
