Objective To evaluate the safety and efficacy of transcatheter arterial chemoembolization(TACE)combined with lenvatinib and camrelizumab in the treatment of advanced hepatocellular carcinoma(HCC).Methods The clinical data of a total of 63 patients with advanced HCC,who received TACE combined with lenvatinib and camrelizumab(triple therapy)or TACE combined with lenvatinib(dual therapy)at the Jingmen Municipal People's Hospital of China between April 2020 and December 2021,were retrospectively analyzed.Triple therapy group had 30 patients,and dual therapy group had 33 patients.The post-treatment tumor response,disease progression-free survival(PFS),overall survival(OS),and the incidence of adverse drug reactions were recorded.Results The median follow-up period of the two groups was 14 months(range of 4-26 months).Compared with the dual therapy group,in the triple therapy group the objective response rate(ORR)was remarkably higher(83.3%vs.57.6%,P=0.026),the disease control rate(DCR)was obviously higher(93.3%vs.69.7%,P=0.039),the median PFS was significantly longer(8.0 months vs.5.0 months,P＜0.01),and the median OS was strikingly longer(24.0 months vs.12.0 months,P=0.004).No statistically significant difference in the incidence of adverse drug reactions existed between the two groups(P＞0.05).Conclusion For the treatment of advanced HCC,TACE combined with lenvatinib and camrelizumab is clinically safe and effective.(J Intervent Radiol,2024,32:57-62)

Objective:To evaluate the diagnostic value of rapid on-site evaluation (ROSE) performed by endoscopists for solid pancreatic lesions requiring tissue for immunohistochemistry (IHC) staining with different approach of endoscopic ultrasound-guided tissue acquisition (EUS-TA).Methods:After screening 1 573 cases who underwent EUS-TA operation at the Endoscopy Center of Peking Union Medical College Hospital between August 2018 and October 2022, a total of 65 cases of solid pancreatic lesions whose diagnosis rely on IHC staining was collected and summarized with clinical data of each case. Among 65 cases, there were 46 cases of pancreatic neuroendocrine tumors (PNETs), 13 cases of pancreatic solid pseudo-papillary tumors (SPTs), and 6 cases of lymphomas and mesenchymal. Patients were categorized into ROSE group (36 cases) and non-ROSE group (29 cases) according to the presence or absence of endoscopists performed ROSE during EUS-TA operation. They were further divided into subgroups of FNA-ROSE (26 cases), FNB-ROSE (10 cases), FNA-non-ROSE (24 cases) and FNB-non-ROSE (5 cases) according to the type of EUS-TA. Diagnostic accuracy and IHC success rate were compared between different groups and subgroups. Binomial logistic multifactorial regression analysis was used to evaluate the influence of ROSE and EUS-TA type on diagnostic accuracy and IHC success rate.Results:There were no statistically significant differences between ROSE group and non-ROSE group in terms of age, gender, bilirubin level, CA19-9 level, lesion site, lesion size, composition ratio of diagnosis, and surgical rate. The differences in mean size of lesions, needle gauge, location of puncturation, and number of needle pass between subgroups were not statistically significant. The diagnostic accuracy was 88.9% in ROSE group and 79.3% in non-ROSE group, and the difference between the two groups was statistically significant ( P=0.023). The diagnostic accuracy of FNA-ROSE group was higher than that of FNA-non-ROSE group (88.5% vs 75.0%), but the difference was not statistically significant ( P>0.100). The differences in diagnostic accuracy and success rate of IHC between FNB-ROSE group and FNB-non-ROSE group were not statistically significant. Binomial logistic multifactorial regression analysis did not reveal any independent influences on diagnostic accuracy. Conclusions:ROSE performed by endoscopists improved diagnostic accuracy of EUS-TA in solid pancreatic lesions requiring IHC staining, and therefore is potentially valuable for improving the diagnostic efficiency of EUS-TA for such diseases.

Objective:To analyze clinical characteristics of primary pancreatic lymphoma (PPL) patients.Methods:Clinical features of 22 patients diagnosed as PPL admitted to Peking Union Medical College Hospital from January 2002 to May 2023 were analyzed retrospectively.Results:The median age was 56.4±13.3 years. The median time from onset to diagnosis was 1.0 (1.0, 3.0) months. The main clinical manifestations were abdominal pain (15/22), weight loss (14/22) and jaundice (10/22). Elevated lactate dehydrogenase (LDH) was observed in 15/20 (75%) patients. Only 2 (2/9, 22.2%) patients had increased CA199 levels and 2 (2/9, 22.2%) patients had increased CEA levels. The maximum tumor diameter was 5.0 (3.8, 6.9) cm. Contrast-enhanced CT mostly showed low enhancement lesions. Major pancreatic duct dilatation were rare on CT scan (4/20). Fifteen patients were confirmed by pancreatic pathology, of which 8 were obtained by surgery, 4 were obtained by CT or ultrasound-guided percutaneous biopsy, and 3 were obtained by EUS-FNA. The main pathological type was diffuse large B-cell lymphoma (14/22). 19 patients received chemotherapy, and 6 patients died with a median follow-up of 5.0 (1.5, 35.5) months.Conclusions:PPL is rare and easy to be misdiagnosed. Elevated LDH levels, normal tumor markers, and non-dilatation of main pancreatic duct are important diagnostic clues. It is important to obtain pathology by EUS-FNA and other methods for definite diagnosis.

To explore the application value of endoscopic ultrasound fine-needle aspiration (EUS-FNA) and endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis and treatment ofpatients with pancreatic cancer combined with obstructive jaundice.

Objective:To assess the efficacy of endoscopic transmural drainage, transpapillary drainage and their combination in reducing cyst recurrence in patients with disconnected pancreatic duct syndrome (DPDS).Methods:A retrospective study was conducted involving 22 patients diagnosed as having DPDS in Peking Union Medical College Hospital from January 2018 to December 2022. Patient data including clinical information, imaging characteristics, drainage technique, complications, and outcomes were extracted from the medical records and telephone follow-up.Results:There were 27 endoscopic treatments in 22 patients, which were categorized into 3 groups based on the procedural approach: transmural in 11 cases, transpapillary in 8, and the combination of both in 8. The combined drainage group exhibited a significantly higher drainage success rate (100.0%, 8/8) compared with the transpapillary group (50.0%, 4/8, P=0.012), with no significant difference compared with the transmural group [90.9% (10/11), P=0.621]. The one-year recurrence rate was significantly lower in the combined drainage group [0.0% (0/8)] than that in the transmural drainage group [55.6% (5/9), P=0.018], and transpapillary drainage alone [42.9% (3/7)] though it did not reach significance ( P=0.085). No significant differences were observed in treatment success rate [45.5% (5/11), 75.0% (6/8) and 87.5% (7/8), H=3.890, P=0.143], or complication incidence [54.5% (6/11), 75.0% (6/8) and 25.0% (2/8), H=3.909, P=0.142]. Conclusion:Transmural drainage combined with pancreatic duct stent placement results in satisfactory drainage of cystic fluid in the short term and significantly reduces one-year recurrence among patients with DPDS.

Background The risks of unhealthy working mood and physical and mental health problems are high in the workers of petrochemical enterprises. Resilience is a positive psychological factor, which can provide positive ability to manage stress and job burnout, relieve tension, depression, anxiety, and other psychological discomfort. Objective To explore the moderating or mediating effect of resilience on the association between job burnout and sleep disorders in workers of petrochemical enterprises. Methods A survey with questionnaire of general information, resilience, job burnout (including exhaustion, cynicism, and professional efficacy), and sleep disorders was conducted among 1087 workers who were selected by cluster sampling from a petrochemical enterprise in Henan Province in April 2022. Mann-Whitney U test and Kruskal-Wallis H test were used to test the differences of scores among different demographic groups. Resilience, job burnout (including exhaustion, cynicism, and professional efficacy), and sleep disorder scores were analyzed by partial correlation analysis. The moderating effect of resilience was examined by linear regression analysis, and the mediating effect of resilience by Bootstrap method. Results A total of 861 questionnaires were collected, of which 857 were effective, and the effective rate was 99.5%. The M (P₂₅, P₇₅) of job burnout score was 1.24 (0.65, 2.22) and the incidence of job burnout was 36.4% (312/857); the scores [M (P₂₅, P₇₅)] of exhaustion, cynicism, and professional efficacy were 1.40 (0.80, 3.00), 1.00 (0.20, 1.60), and 5.50 (4.00, 6.00), respectively. The M (P₂₅, P₇₅) of resilience score was 36.00 (30.00, 41.00). The M (P₂₅, P₇₅) of sleep disorder score was 11.00 (7.00, 15.00). The partial correlation analysis results showed that job burnout, exhaustion, and cynicism were negatively correlated with resilience (r=−0.387, −0.248, −0.247, P<0.01), and positively correlated with sleep disorders (r=0.455, 0.445, 0.357, P<0.01); professional efficacy was positively correlated with resilience (r=0.366, P<0.01) and negatively correlated with sleep disorders (r=−0.184, P<0.01); resilience was negatively correlated with sleep disorders (r=−0.349, P<0.01). The linear regression analysis results found that job burnout, exhaustion, and cynicism elevated the risk of sleep disorders (P<0.01), resilience lowered the risk of sleep disorders (P<0.01); but the relationship between job burnout (exhaustion, cynicism, and professional efficacy) and sleep disorders was not moderated by resilience (P＞0.05). The mediating effect test showed that resilience played a partial mediating role in the associations of job burnout, exhaustion, cynicism, and professional efficacy with sleep disorders, the mediating effects were 0.522 (95%CI: 0.283-0.777), 0.310 (95%CI: 0.188-0.453), 0.364 (95%CI: 0.228-0.524), −0.542 (95%CI: −0.741-−0.366) and the mediating effects accounted for 17.31%, 14.12%, 19.24%, and 64.72% of the total effects, respectively. Conclusion The relationship between job burnout and sleep disorders is partially mediated by resilience among workers in the selected petrochemical company, but no moderating effect is found.

Objective:To investigate the role of endoscopic ultrasonography (EUS) in differentiating between autoimmune pancreatitis (AIP) and pancreatic cancer (PC).Methods:Data of 133 patients with AIP and 113 patients with PC who underwent EUS because of obstructive jaundice at Peking Union Medical College Hospital from January 2013 to December 2018 were retrospectively analyzed in the study, and were randomly divided into either a derivation sample or a validation sample using 1∶1 allocation according to the random number. In the derivation sample, 10 EUS characteristics were used to construct a prediction model to distinguish between AIP and PC, in which predictors were identified by multivariate stepwise logistic regression analysis and predictive efficacy was evaluated by receiver operating characteristics (ROC) curve analysis. The predictive efficacy was assessed in the validation sample. In view of the subjectivity in the judgment of diffuse/focal hypoechogenicity, 2 prediction models were designed in order to avoid bias.Results:By multivariate stepwise logistic regression analysis, diffuse hypoechogenicity ( OR=591.0, 95% CI: 98.8->999.9, P<0.001) and vessel involvement ( OR=11.9, 95% CI: 1.4-260.2, P=0.023) were identified as statistically significant predictors for distinguishing AIP from PC. EUS characteristics excluding diffuse/focal hypoechogenicity were stepped by logistic regression, which showed that hyperechoic foci/strands ( OR=177.3, 95% CI: 18.7->999.9, P<0.001), pancreatic duct dilation ( OR=60.5, 95% CI: 6.2->999.9, P=0.004), bile duct wall thickening ( OR=35.4, 95% CI: 3.7->999.9, P=0.009), lymphadenopathy ( OR=16.8, 95% CI: 1.7-475.2, P=0.038) and vessel involvement ( OR=22.7, 95% CI: 2.0-725.7, P=0.028) were statistically significant predictors to distinguish the two diseases. Both prediction models were built in the derivation sample, with area under the ROC curve of 0.995 and 0.979 respectively. In the validation sample, sensitivity, specificity, accuracy, positive predictive value and negative predictive value of both prediction models were all >90% by using the optimal cutoff value. Even for discrimination between focal AIP and PC, sensitivity and accuracy of both models were >90%, and specificity, positive predictive value and negative predictive value were all >85%. Conclusion:The 2 prediction models have good differential predictive value, and EUS is a useful tool to differentiate between AIP and PC.

Objective:To investigate the clinical significance of plasma thrombin-antithrombin complex (TAT) levels in patients with sepsis-induced cardiomyopathy(SIC).Methods:One hundred and seven sepsis patients who were admitted to intensive care units (ICU) of the 908th Hospital of Chinese PLA Logistical Support Force were enrolled in the study. Patients were divided into sepsis group ( n=79) and the sepsis-induced cardiomyopathy group ( n=28) according to whether the cardiac ultrasound examination in 2 hours after admission, and the differences of each indicators between the two groups were compared including acute physiological and chronic health score (APACHEⅡ), lactate, blood routine, liver and kidney function, cardiac troponin I, N-terminal?pro-brain?natriuretic?peptide (NT-pro BNP), conventional coagulation tests and molecular markers of coagulation [tissue plasminogen activator-inhibitor complex (t-PAIC), thrombomodulin (TM), TAT, plasmin-α2-plasmin inhibitor complex (PIC)].Logistical?regression?was?used?to analyze the?risk?factors?for sepsis-induced cardiomyopathy and the receiver operating characteristic (ROC) curve was to analyze their cut-off values. The effect of low-molecular-weight heparin anticoagulation therapy on sepsis patients with TAT>8.26 ng/ml was evaluated by Kaplan-Meier analysis. Results:Compared with the cardiac troponin I[0.02(0.01, 0.09) ng/ml], NT-proBNP [1 118.09 (333.25, 2687.00) pg/ml], lactate[1.35(0.90, 2.60) mmol/L], TAT[6.50(3.94, 12.14) ng/ml], PIC[1.256 (0.668, 2.045) μg/ml] and t-PAIC[10.50 (6.70, 21.30) ng/ml] in sepsis group, the cardiac troponin I [0.75(0.01, 6.02) ng/ml], NT-proBNP[12 125.14(4 185.89, 33 611.62) pg/ml], lactate[2.35(1.43, 4.34) mmol/L], TAT[19.85 (9.08, 45.78) ng/ml], PIC[2.115 (0.878, 4.114) μg/ml] and t-PAIC [22.03(15.61,33.20) ng/ml] levels in the sepsis-induced cardiomyopathy group were significantly increased ( P<0.05). Logistical regression showed that positive NT-pro BNP and elevated TAT levels were independent risk factors for sepsis-induced cardiomyopathy. ROC curve analysis showed that the area under the curve of plasma TAT level for predicting sepsis-induced cardiomyopathy was 0.78. The sensitivity and specificity at the cut-off value of plasma TAT level with 8.26 ng/ml were 0.82 and 0.63, respectively. Conclusions:The elevated TAT level was an independent risk factor for the development of sepsis-induced cardiomyopathy. Low-molecular-weight heparin anticoagulation therapy can improve the 28-day survival rate of sepsis patients with TAT>8.26 ng/ml.

Objective:To explore the value of the static and dynamic pelvic floor MRI and diffusion tensor imaging (DTI) in evaluating the morphology and function of urethra in patients with stress urinary incontinence (SUI).Methods:From July 2020 to February 2021, a total of 28 patients with SUI and 45 age-matched healthy controls were prospectively collected at the First Affiliated Hospital of Zhengzhou University. The static and dynamic pelvic floor MRI and DTI were performed for all subjects. The thickness of internal and external sphincter of middle urethra were measured on static MRI images. The functional urethral length (FUL) was measured both on static and maximal strain phase of dynamic MRI images, then the difference of FUL was calculated. The presence of bladder neck funneling and urethra opening were observed on static and dynamic MRI. The muscle fiber bundle image of urethral sphincter complex was obtained by post-processing of DTI original images. The anisotropy fraction (FA), apparent diffusion coefficient (ADC) and three eigenvalues (λ1, λ2, λ3) of annular sphincter and central longitudinal muscle in middle urethra were measured. The independent sample t test and chi-square test were used to analyse the difference of measured parameters in MRI, parameters of DTI and imaging signs between the two groups. Results:Compared with healthy controls, the SUI patients showed that the thickness of external sphincter in middle urethral and FUL in static status and maximal strain phase were significantly decreased ( t=-3.95, -5.72, -8.41, all P<0.001), the difference of FUL between static status and maximal strain phase was significantly increased ( t=4.41, P<0.001). The positive rate of bladder neck funneling in static status and maximal strain phase, urethral opening in maximal strain phase of SUI group increased significantly (χ2=23.09 , 22.25, 26.59, all P<0.001). In SUI group, the FA value of middle urethral annular sphincter decreased significantly ( t=-3.48, P=0.001), while the ADC, λ2 and λ3 values increased significantly ( t=3.19, 2.15 , 2.06, and P=0.002, 0.038 , 0.046, respectively). There was no significant difference in DTI parameters of middle urethral longitudinal muscle between the two groups (all P>0.05). Conclusions:Static and dynamic MRI and DTI techniques can objectively evaluate the changes of urethral morphology and function of SUI patients. The thinning of the external sphincter in the middle urethra, shortening of the FUL and the destruction of the microstructure of the annular sphincter fiber bundle were the main alterations of SUI patients.
