Objective To investigate the heterogeneity and key molecular features of epithelial cells in triple-negative breast cancer (TNBC), identify prognostic biomarkers, and develop a robust survival prediction model. Methods Using TNBC single-cell transcriptomic data, epithelial cells were extracted, normalized, and subclustered to characterize their molecular signatures and functional differences. High-dimensional weighted gene co-expression network analysis (hdWGCNA) was applied to establish co-expression modules in epithelial cells. Multiple machine learning algorithms were integrated to select key prognostic genes and develop a risk-score model, whose performance was evaluated using receiver operating characteristic (ROC) curves and Kaplan-Meier (K-M) survival analysis. In addition, the immune microenvironment features and potential drug-response differences between the high- and low-risk groups were systematically assessed. Finally, PCR was performed to validate the expression differences of the key genes between tumor and normal tissues. Results We characterized the composition and molecular features of TNBC epithelial subpopulations and identified a TNBC-associated epithelial subset. By integrating hdWGCNA with machine learning approaches, 10 key genes were selected to construct a prognostic model, which effectively stratified patients into distinct survival-risk groups and demonstrated favorable predictive performance in ROC and K-M analyses. Immune profiling revealed the differences in the infiltration levels of seven immune cell types and immune function-related features between the high- and low-risk groups. Drug-sensitivity analysis suggested potential differential responses to eight agents across the risk groups. PCR validation further confirmed the differential expression of the ten signature genes between tumor and normal tissues. Conclusion This study reveals epithelial heterogeneity in TNBC at single-cell resolution and establishes a 10-gene prognostic model, which may facilitate the stratification of TNBC risk and the evaluation of immune characteristics and potential therapeutic strategies.

This study explored the pathogenesis and treatment of postoperative pulmonary nodules from the perspective of deficient qi resulting into retention of pathogens,thus to expand the approach to its diagnosis and treatment.It is believed that deficient qi resulting into retention of pathogens contributes to the key pathogenesis of pulmonary nodules.As the root cause of the disease,deficient qi usually involves the deficiency of the lung and spleen.And as the incidental manifestations,retention of pathogens refers to the accumulation of pathological products such as stagnated qi,phlegm-stasis,and turbid toxins in the lung collaterals.The pathogenesis of postoperative pulmonary nodules is characterized by the collapse of pectoral qi,aggravated deficient qi,and the lingering presence of the relieved qi stagnation,phlegm-stasis,and turbid toxins.Based on the pathogenesis of deficient qi resulting into retention of pathogens,the treatment principles for postoperative pulmonary nodules should focus on tonifying deficiency and lifting collapse,and relieving qi stagnation and unblocking obstruction.Tonifying deficiency needs to prioritize strengthening the spleen and nourishing the lung to go first,lifting collapse aims at elevating the pectoral qi,relieving qi stagnation focuses on regulating qi and harmonizing the liver,and unblocking obstruction mainly involves resolving phlegm-stasis and eliminating turbid toxins.The pathogenesis of deficient qi resulting into retention of pathogens aligns with the pathological features and syndrome evolution of postoperative pulmonary nodules,and will provide dynamic and systematic guidance for its clinical diagnosis and treatment.

Objective:To summarize the clinical characteristics, diagnostic and therapeutic approaches, and prognosis of posttransplant lymphoproliferative disease (PTLD) following kidney transplantation.Methods:A retrospective case series analysis was conducted on 7 PTLD patients after kidney transplantation treated in the Department of Transplant Oncology, Tianjin First Central Hospital between January 2018 and December 2023. Clinical features, laboratory findings, imaging and pathological characteristics, treatment modalities, and outcomes were analyzed.Results:Among 7 PTLD patients, there were 5 male and 2 females with a median age of 41 (17-65) years. The median time of onset after operation was 4 (0.5-11) years. Among them, 2 patients had early onset (<1 year post-transplantation) and 5 patients had late onset (>1 year). The clinical manifestations included abdominal mass in 4 cases, anemia in 4 cases, fever in 3 cases, lymphadenopathy in 4 cases, gastrointestinal bleeding in 1 case, abdominal pain in 2 cases, and intestinal obstruction in 2 cases. Pathological types included diffuse large B-cell lymphoma in 4 cases, Burkitt lymphoma in 1 case, marginal zone lymphoma in 1 case, and polymorphic PTLD in 1 case. Reducing the immunosuppressant level was the basal treatment plan, and rituximab, chemotherapy, surgery, radiotherapy and CD19-targeted chimeric antigen receptor therapy were given according to the pathological classification. Until the date of submission, 2 patients had died, 4 had a complete response, and 1 had a partial response. None of the patients had acute rejection, and 1 patient had chronic renal insufficiency.Conclusions:PTLD after kidney transplantation presents with nonspecific manifestations, necessitating prompt imaging and histopathological evaluation for definitive diagnosis. At the same time, a series of measures should be given to improve the prognosis, including discontinuous use of anti-metabolic drugs, dosage decline of calcitric phosphatase inhibitor by 50% or convert it to sirolimus treatment, and corresponding treatment according to the specific conditions of the recipient.

Chronic pancreatitis is a chronic inflammatory disease characterized by progre-ssive fibrosis of pancreatic tissue. Its pathological features primarily include parenchymal fibrosis, intraductal stone formation or calcification deposits, as well as segmental stenosis and dilation of the pancreatic duct. Prolonged chronic inflammatory stimulation not only leads to progressive pancreatic dysfunction but may also trigger the formation of pancreatic pseudocysts and even malignant transformation. In the comprehensive treatment of chronic pancreatitis, the core clinical goals are the removal of pancreatic duct stones, restoration of unobstructed pancreatic duct drainage, and preservation of residual pancreatic function. Traditional treatment strategies have been based on the principle of progressive intervention and early surgical management. In recent years, with advancements in extracorporeal shock wave lithotripsy, the application of new techniques such as endoscopic retrograde cholangiopancreatography combined with laser lithotripsy under direct cholan-gioscopic visualization, and improvements in pancreas-preserving surgical approaches, the debate over the superiority of progressive intervention versus early surgical treatment has intensified. Against this backdrop, the treatment mode of Xi′an Jiaotong University Pancreatic Disease Center (hereinafter referred to as "Western Pancreas") has emerged, emphasizing a personalized, multimodal treatment strategy based on different types of pancreatic duct stones. The treatment mode of "Western Pancreas" integrates lithotripsy, endoscopic treatment, and surgical interventions to optimize patient outcomes. By conducting a comprehensive analysis of domestic and international pancreatic duct stone classi-fication systems and drawing from our team′s clinical experience in managing over a thousand cases of chronic pancreatitis, the authors have further refined and proposed a classification system for pancreatic duct stones under the treatment mode of "Western Pancreas". This refinement aims to enhance the overall diagnostic and therapeutic standards for chronic pancreatitis.
