Objective To explore the influencing factors of delayed bleeding after endoscopic gastric polypectomy in antithrombotic patients.Methods A retrospective case-control study was conducted,42 patients who experienced delayed bleeding after endoscopic gastric polypectomy during antithrombotic therapy at Dongguan Eighth People's Hospital from April 2021 to April 2024 were selected as the bleeding group,and 84 patients who underwent the same surgery during the same period without delayed postoperative bleeding were selected as the non-bleeding group.The general data,polyps and antithrombotic treatment of the two groups were compared.The influencing factors of delayed bleeding after endoscopic gastric polypectomy in patients with antithrombotic treatment were analyzed by conditional Logistic regression,and the predictive value was evaluated by the receiver operating characteristic(ROC)curve.Results The maximum polyp diameter of the bleeding group was larger than that of the non-bleeding group(P<0.05).There were significant differences in the number of antithrombotic drugs and the management of antithrombotic drugs between the two groups(P<0.05).Logistic regression analysis showed that the large maximum polyp diameter before surgery(OR=4.056,95%CI:2.116 to 7.775),the use of multiple antithrombotic drugs before surgery(OR=5.308,95%CI:1.516 to 18.583),and the withdrawal of all antithrombotic drugs but the application of renal replacement therapy(OR=7.167,95%CI:1.921 to 26.734)were the risk factors for postoperative delayed bleeding(P<0.05).ROC curve showed the area under the curve of the large maximum polyp diameter before surgery,the use of multiple antithrombotic drugs before surgery,and the withdrawal of all antithrombotic drugs but the application of renal replacement therapy for predicting postoperative delayed bleeding were 0.882(95%CI:0.812 to 0.932),0.702(95%CI:0.614 to 0.781)and 0.746(95%CI:0.661 to 0.820).Conclusion The large maximum polyp diameter before surgery,preoperative use of multiple antithrombotic drugs,and the application of renal replacement therapy are influencing factors for delayed bleeding after endoscopic gastric polypectomy in antithrombotic patients.

BACKGROUND: Perioperative treatment has become an increasingly important aspect of the management of patients with non-small cell lung cancer (NSCLC). Small-scale clinical studies performed in recent years have shown improvements in the major pathological remission rate after neoadjuvant therapy, suggesting that it will soon become an important part of NSCLC treatment. Nevertheless, neoadjuvant immunotherapy may be accompanied by serious adverse reactions that lead to delay or cancelation of surgery, additional illness, and even death, and have therefore attracted much attention. The purpose of the clinical recommendations is to form a diagnosis and treatment plan suitable for the current domestic medical situation for the immune-related adverse event (irAE). METHODS: This recommendation is composed of experts in thoracic surgery, oncologists, thoracic medicine and irAE related departments (gastroenterology, respirology, cardiology, infectious medicine, hematology, endocrinology, rheumatology, neurology, dermatology, emergency section) to jointly complete the formulation. Experts make full reference to the irAE guidelines, large-scale clinical research data published by thoracic surgery, and the clinical experience of domestic doctors and publicly published cases, and repeated discussions in multiple disciplines to form this recommendation for perioperative irAE. RESULTS: This clinical recommendation covers the whole process of prevention, evaluation, examination, treatment and monitoring related to irAE, so as to guide the clinical work comprehensively and effectively. CONCLUSIONS Perioperative irAE management is an important part of immune perioperative treatment of lung cancer. With the continuous development of immune perioperative treatment, more research is needed in the future to optimize the diagnosis and treatment of perioperative irAE.

Objective To establish the quality standard for Sanyuan Rupixiao Gel Paste. Methods Sparganii Rhizoma, Gleditsiae Sinensis Fructus, Cyperi Rhizoma and Impatientis Semen were identified by TLC method. The content of tetrahydropalmatine was determined by HPLC. Waters symmetry column was used with the mobile phase of acetonitrile-0.1% phosphatic acid in a gradient manner (pH was adjusted to 6.4 by triethylamine) (55:45) at the detection wavelength of 280 nm. The flow rate was 1.0 mL/min at the column temperature of 30 ℃. Results The spots in TLC were clear without any interference;tetrahydropalmatine showed a good linear relation in the range of 0.092–1.84 μg;the average recovery was 100.15%with RSD of 1.58%(n=6). Conclusion The method is simple and accurate with high reproducibility, which can be used for the quality control of Sanyuan Rupixiao Gel Paste.
