Objective:To analyze and explore the diagnostic value of endoscopic submucosal dissection (ESD) for primary gastrointestinal lymphoma (PGIL).Methods:A retrospective analysis was conducted on the clinical and pathological data from 37 patients with suspected PGIL and admitted to Zhongshan Hospital, Fudan University and Xiamen Hospital, Zhongshan Hospital, Fudan University between January 2021 and December 2023. The diagnostic accuracy for PGIL of initial endoscopic conventional biopsies was compared with that of ESD biopsies.Results:Among these patients, 6 were diagnosed as having primary gastrointestinal lymphoma by routine endoscopic biopsy, with a diagnostic rate of 16.22% (6/37). Of the 22 patients who underwent ESD, 20 were diagnosed as having primary gastrointestinal lymphoma, achieving a diagnostic rate of 90.91% (20/22), which was significantly higher than that of initial endoscopic routine biopsies ( χ2=31.228, P<0.05). Conclusion:ESD demonstrates significant diagnostic value for PGIL.

Objective:To explore the clinical characteristics of patients with porto-sinusoidal vascular disease (PSVD) complicated with esophageal and gastric varices, and to evaluate the effect of portal vein pressure (PVP) on esophageal and gastric varices bleeding and rebleeding after endoscopic treatment.Methods:Patients who were hospitalized in the Department of Gastroenterology of the Zhongshan Hospital, Fudan University due to portal hypertension from July 2022 to October 2024, underwent liver biopsy for diagnosis of PSVD, and received direct PVP measurement were included. Their clinical manifestations, liver histopathological characteristics were analyzed, and the prognosis was followed up.Results:A total of 29 patients were included, and 19 patients had experienced rupture and bleeding of esophageal and gastric varices. Compared with the non-bleeding group, the hemoglobin level of patients in the bleeding group was lower and the international normalized ratio was higher (all P<0.05). There was no statistically significant difference between the two groups in other laboratory examination indicators, complications of portal hypertension, combined diseases, etc. (all P>0.05). The pathology of liver biopsy suggests that dilation of the hepatic sinuses and abnormalities of the central vein are common pathological changes. The direct PVP of patients in the bleeding group was significantly higher than that in the non-bleeding group [28.0(24.5-31.0)mmHg vs 18.5(10.5-23.8)mmHg, P=0.011]. However, there was no statistically significant difference in the measured values of liver wedge pressure, free pressure and hepatic venous pressure gradient (HVPG) between the two groups of patients (all P>0.05). Correlation analysis revealed that there was no significant correlation between HVPG and PVP ( R2=0.129 9, P=0.076 7). Grouped according to the median PVP value of 25 mmHg, the risk of esophageal and gastric variceal rupture and bleeding in the high PVP group (≥25 mmHg) was significantly higher than that in the low PVP group (<25 mmHg) (14/16 vs 5/13, P=0.016). The risk of rebleeding after endoscopic treatment in patients with high PVP (4/13) was higher than that in patients with low PVP (0/4). Conclusions:Patients with porto-sinusoidal vascular disease complicated with portal hypertension are often accompanied by rupture and bleeding of esophageal and gastric varices. HVPG cannot accurately reflect the portal vein pressure. The risk of rupture and bleeding of esophageal and gastric varices and rebleeding in patients with elevated portal vein pressure is significantly increased.

Objective:To explore the effect of inflammatory cell levels on the anticoagulant efficacy in patients with liver cirrhosis complicated with portal vein thrombosis (PVT).Methods:A total of 106 patients with liver cirrhosis complicated with PVT who visited the Zhongshan Hospital, Fudan University from 2017 to 2022 were prospectively included. The PVT grade and recanalization were evaluated by imaging. Cox regression was used to analyze the predictive factors of anticoagulation efficacy. The time-dependent receiver operating characteristic (ROC) curve was used to determine the optimal cutoff value of inflammatory cells for predicting anticoagulation efficacy. The Kaplan-Meier method was used to compare the 1-year PVT recanalization rate of patients with different levels of inflammatory cells.Results:Univariate analysis showed that Child-Pugh score ( HR=1.41), D-dimer ( HR=0.98), platelet ( HR=0.98), C-reactive protein to lymphocyte ratio ( HR=1.01), monocyte ( HR=0.21), lymphocyte ( HR=0.34), and prothrombin time( HR=1.32) was related to the improvement of PVT (all P<0.05). Multivariate analysis confirmed that lymphocytes ( HR: 0.41, 95% CI: 0.20-0.85, P=0.016) and prothrombin time ( HR: 1.23, 95% CI: 1.01-1.50, P=0.036) were independent predictors of anticoagulant efficacy. Grouped according to the ROC cutoff value, the 1-year recanalization rate of PVT in the high-level lymphocyte group (4.55% vs 32.84%, P=0.012) and the high-level monocyte group (5.56% vs 31.4%, P=0.028) was significantly lower than that in the low-level group. After excluding patients undergoing splenectomy, the recurrence rate in the high-level lymphocyte group was still lower than that in the low-level group (6.25% vs 33.77%, P=0.038). Conclusions:Among patients with liver cirrhosis accompanied by PVT, high levels of lymphocytes and monocytes are the key factors for the poor efficacy of anticoagulation therapy. For PVT patients with poor anticoagulation efficacy, the therapeutic strategy of anti-inflammatory combined with anticoagulation can be considered for exploration in the future.

Objective:To analyze the application of Sengstaken-Blakemore tubes combined with endoscopic intervention on the prognosis of patients with acute esophageal and gastric variceal rupture and bleeding due to portal hypertension in liver cirrhosis, and to explore the impact of Sengstaken-Blakemore tubes combined with endoscopic intervention on the prognosis of patients.Methods:A retrospective study included patients with liver cirrhosis who visited the Zhongshan Hospital, Fudan University from January 2023 to July 2024 due to acute upper gastrointestinal bleeding, had no response to drug treatment and unstable hemodynamics, and received the Sengstaken-Blakemore tubes compression hemostasis. According to whether endoscopic intervention was received or not, the patients were divided into the endoscopic intervention group and the non-endoscopic intervention group. The medication and subsequent treatment of the patients were analyzed, and the survival of the patients 28 days after bleeding was followed up. Kaplan-Meier survival analysis and Cox regression analysis were used to evaluate the effect of endoscopic intervention on the 28-day mortality rate of patients.Results:A total of 31 cases successfully had three-lumen two-cystic tubes indwelled. Among them, 8 cases further received endoscopic examination and intervention, and 23 cases did not receive endoscopic examination. During the 28-day follow-up after bleeding, a total of 20 cases died. The Kaplan-Meier survival analysis showed that the 28-day mortality rate in the endoscopic intervention group was significantly lower than that in the non-endoscopic intervention group (25.0% vs 78.3%, P=0.007). Multivariate Cox regression analysis showed that endoscopic intervention was an independent protective factor for 28-day mortality ( HR: 0.14, 95% CI: 0.03-0.63, P=0.01). In addition, the severity of bleeding and prothrombin time were also important factors affecting the prognosis of patients. Conclusions:The Sengstaken-Blakemore tubes, as an important hemostasis method for acute esophageal and gastric variceal rupture and bleeding, can buy time for subsequent endoscopic treatment, but the risk of complications is relatively high. Creating conditions for early endoscopic intervention as early as possible can significantly reduce the mortality rate of patients and improve the prognosis of patients with liver cirrhosis.

Objective:To investigate the effect of Early infarct growth rate(EIGR) on the prognosis of patients with acute large vessel occlusive ischemic stroke.Methods:A total of 164 patients with acute large vessel occlusive ischemic stroke were enrolled in the emergency department of the First Affiliated Hospital of Nanjing Medical University from January 1, 2020 to December 31, 2022.According to the change of the National Institutes of Health Stroke Scale (NIHSS) score at admission and 72 h after treatment, the patients were divided into good prognosis group and poor prognosis group. The basic clinical data of the two groups were observed and compared. The risk factors of poor prognosis were analyzed by univariate regression. The effect of EIGR on prognosis after age stratification was further analyzed.Results:Comparing the clinical data of the two groups, there was no difference in EIGR (mL/h) (7.67 vs. 8.24, P=0.211) between the two groups. The product between EIGR and age was included as the interaction term, and the result of the interaction term in the model was statistically significant ( OR=1.002, 95% CI: 1.000-1.003, P=0.032) .Moreover, the result was still statistically significant after adjusting for relevant variables (gender, history of hypertension, history of atrial fibrillation, history of diabetes, history of coronary heart disease, and history of stroke) ( OR=1.002, 95% CI:1.000-1.003, P=0.027). Subgroup analysis was performed according to the median age (71 years). In the elderly group, the proportion of poor prognosis was higher with fast core infarction growth rate defined by 25 mL/h and 15 mL/h ( P < 0.05).In the younger age group, there was no significant difference in the proportion of poor prognosis in the fast core infarction growth rate compared with the slow type ( P > 0.05). Conclusions:EIGR can predict the early clinical outcome early in elderly patients with large vessel occlusive ischemic stroke.

Objective:To explore the changes of iron metabolism in patients with hepatitis B cirrhosis and esophageal and gastric varices complicated with portal vein thrombosis.Methods:This study was a cross-sectional study. 253 patients with hepatitis B cirrhosis with esophageal and gastric varices who were hospitalized in the Zhongshan Hospital, Fudan University from January 1, 2020 to December 31, 2021 were included in this study. They were divided into portal vein thrombosis group ( n=57) and non portal vein thrombosis group ( n=196) according to the presence or absence of portal vein thrombosis. The iron metabolism characteristics of the two groups were compared, and subgroups were analyzed according to the presence or absence of ascites, platelet count level, D-dimer level, and Child grade. The factors related to portal vein thrombosis were screened through multivariate logistic regression analysis. Results:The ratio of Child pugh B/C, ascites, D-dimer and platelet count in patients with hepatitis B cirrhosis and esophageal and gastric varices complicated with portal vein thrombosis was higher (all P<0.05). Patients with portal vein thrombosis had higher levels of soluble transferrin receptor [2.4(1.8, 3.6)mg/L vs 1.8(1.3, 2.7)mg/L, P=0.006], and lower levels of ferritin [33.1(18.9, 63.3)ng/ml vs 57.7(19.4, 142.5)ng/ml, P=0.038]. Layered analysis showed that ascites, platelet count levels, D-dimer levels, and Child-pugh grade did not affect the negative correlation trend between ferritin and portal vein thrombosis, and the positive correlation trend between soluble transferrin receptors and portal vein thrombosis. Moreover, soluble transferrin receptors showed a statistically significant positive correlation with portal vein thrombosis in the absence of ascites, low D-dimer levels, and Child-pugh grade A. Multivariate analysis suggested that after weighing Child-pugh grading, platelet count, and D-dimer levels, ferritin ( OR=0.943, 95% CI: 0.904-0.983, P=0.006) and soluble transferrin receptor ( OR=1.034, 95% CI: 0.001-1.067, P=0.044) were independently associated with portal vein thrombosis. Conclusions:In patients with hepatitis B cirrhosis with esophageal and gastric varices, the characteristics of iron metabolism in patients with portal vein thrombosis are different from those in patients without thrombosis, with higher levels of soluble transferrin receptor and lower levels of ferritin.
