ABSTRACT

Objective:To investigate the risk factor analysis and model prediction of bleeding after endoscopic retrograde cholangiopancreatography in patients with malignant obstructive jaundice (MOJ).Methods:A retrospective analysis was performed on 302 patients with MOJ treated with ERCP who were treated in the No. 363 Hospital Affiliated to Southwest Medical University from January 2015 to June 2021. The general clinical data of the patients were collected, and the biochemical indicators of the pancreatic and bile ducts were detected. The patients were followed up after discharge, and the patients were divided into a bleeding group ( n=47) and a control group ( n=255) according to whether the follow-up patients were bleeding after ERCP. Compared the general and clinical data of the two groups of patients, including age, gender, platelet count, presence of bile duct stones, acute cholangitis, acute pancreatitis, number of stones, intraoperative bleeding, pancreatic cancer, cholangiocarcinoma, large stone diameter, stone incarceration, duodenal papillary diverticulum, and pre-surgical incision. The measurement data that obey the normal distribution were represented by the mean±standard deviation ( ± s), and the two independent sample t test was used for the comparison between groups; the data that do not conform to the normal distribution were represented by M ( Q1, Q3), and the comparison between groups was used Mann-Whitney U test. The comparison of enumeration data between groups adopted chi-square test. Logistic multivariate regression was used to analyze the independent risk factors of postoperative bleeding after ERCP, and a nomogram prediction model was established and verified according to the independent risk factors of postoperative bleeding. Results:The two groups of patients were compared in age, gender, platelet count, bile duct stones, acute cholangitis, acute pancreatitis, the number of stones, intraoperative bleeding and other aspects, the difference was not statistically significant ( P>0.05). The percentages of pancreatic cancer, cholangiocarcinoma, large stone diameter, stone incarceration, duodenal papillary diverticulum, and surgical pre-incision in the bleeding group were 12.77%, 17.02%, 19.15%, 51.06%, 59.57%, and 14.89%, respectively. , the percentages of the control group were 3.92%, 5.10%, 9.02%, 19.22%, 17.65%, and 5.88%, and the difference was statistically significant between the two groups ( P<0.05). Taking postoperative bleeding as the dependent variable, and using the indicators with statistical differences in univariate analysis as independent variables, multivariate Logistic regression analysis showed that the patient had pancreatic cancer ( OR=1.838, 95% CI: 1.524-4.613, P=0.041), cholangiocarcinoma ( OR=2.548, 95% CI: 1.870-5.116, P=0.015), stone incarceration ( OR=3.078, 95% CI: 2.374-6.012, P<0.001), duodenum Intestinal papillary diverticula ( OR=1.140, 95% CI: 1.045-1.628, P<0.001), surgical pre-incision ( OR=1.640, 95% CI: 1.321-1.928, P<0.001) were associated with postoperative bleeding in MOJ patients after ERCP independent risk factors. The predictive ability of duodenal papillary diverticulum was the highest; the predictive ability of stone incarceration and cholangiocarcinoma was the second, and there was no significant difference between them; the predictive ability of pancreatic cancer, stone diameter, and pre-incision on bleeding after ERCP in MOJ patients smaller. Pancreatic cancer, cholangiocarcinoma, large stone diameter, stone incarceration, duodenal papillary diverticulum, and pre-incision scores were 42, 63, 28, 65, 76, and 34 points respectively, and the total score was 308 points corresponding to the nomogram model. The predictive power of the nomogram was 61.6%, and overall, the nomogram had good predictive performance. Harrell concordance index analysis and ROC curve were used to evaluate the model discrimination, the C-index calculation result was 0.826 (95% CI: 0.771-0.847), the ROC curve AUC was 0.843 (95% CI: 0.801-0.884), and the ROC prediction The value and the calculation result of C-index are relatively close. The model discrimination is applied in this study and has a certain prediction effect. The nomogram model in the Calibration curve predicted the probability of postoperative bleeding after ERCP in MOJ patients with high consistency with the actual probability. Conclusion:ERCP is safe and feasible for most patients with MOJ, but for patients with pancreatic cancer, bile duct cancer, large stone diameter, stone incarceration, and duodenal papillary diverticulum, it should be performed with caution, and preoperative incision should be avoided, to reduce the risk of postoperative bleeding. In addition, the nomogram model has a strong predictive ability in predicting bleeding after ERCP in patients with MOJ, which is worthy of reference in clinical research.

ABSTRACT

ObjectiveTo evaluate the significance of CK19 mRNA monitoring in peripheral blood of breast cancer patients.MethodsPeripheral blood samples were collected from 137 breast cancer patients preoperatively,one day post-operation,7 days,1,3,6,12,18,and 24 months after operation.RTPCR was used to detect CK19 mRNA expression.The relationships were analyzed between CK19 mRNA expression and treatment result, between CK19 mRNA expression and clinicopathological parameters.ResultsThere was no significant difference between the level of CK19 mRNA as tested preoperatively,and 1,7 days postoperatively(P > 0.05 ).From one month and thereafter,CK 19 mRNA decreased significantly when compared with that immediate perioperatives ( P < 0.05 ). Postoperative peripheral CK19 mRNA expression increased in those found with recurrent or metastasized tumors ( P < 0.01 ). CK19 mRNA expression does not correlate with patient's menstrual status,estrogen receptor expression,progesterone receptor expression,HER-2 expression and Ki67 proliferation expression (P > 0.05 ). But there was statistically significant correlation between CK19 mRNA expression and tumour size,histology grading,pathological type,lymph node metastasis ( P < 0.01 ).ConclusionsIn breast cancer patients peripheral blood CK19 mRNA expression is correlated with risk clinicopathological parameters, and increases in patients with postoperative recurrence and tumor metastasis.

ABSTRACT

ObjectiveTo explore the value of virtual touch tissue quantification (VTQ) in evaluating Lauren classification of advanced gastric carcinoma.MethodsForty-one patients with gastric cancer proved by endoscopic biopsy performed preoperative VTQ examination,and the findings were compared with postoperative pathologic results via hematoxylin -eosin and Alcian Blue-Periodic Acid Schiff (AB-PAS) staining.ResultsIn 41 patients,26 cases were diagnosed as diffuse type and 15 cases as intestinal type by pathology after operation.The shear wave velocity(SWV) of diffuse type was higher than that of intestinal type [(1.72± 0.83)m/s vs (1.05± 0.66)m/s,t =2.819,P=0.008] measured by virtual touch tissue quantification (VTQ).According to the area under the ROC curve,the cut- off value of SWV in gastric cancer tissues for assessing the diffuse type was 1.045 m/s with a sensitivity of 80.8% and specificity of 73.3 % respectively.ConclusionsVTQ could be considered as a promising method to distinguish the Lauren classification in patients with advanced gastric carcinoma.

ABSTRACT

Benign biliary strictures(BBS) have different etiologies, and the most common causes are strictures secondary to iatrogenic and ischemic injury after hepatobiliary and transplantation surgery. Fibroblast proliferating activity, extracellular matrix overdeposition and scar proliferation are closely related to BBS. The mechanism of development of BBS involves a variety of cells, cytokines and extracellular matrix. In recent years, biological treatment is emerging as an effective option for BBS, but the clinical application is not yet mature and the curative effect needs to be evaluated further in the future.
