ObjectiveTo investigate the safety and efficacy of puncture cyanoacrylate selective seal （PCSS） under endoscopic ultrasound in the treatment of gastroesophageal varices （GOV）. MethodsA total of 100 patients with liver cirrhosis who underwent endoscopic therapy for the secondary prevention of GOV bleeding in Beijing Ditan Hospital， Capital Medical University， from March 1 to December 31， 2023 were enrolled and randomly divided into PCSS group and traditional endoscopy group. The patients were followed up for 6 months after surgery， and the two groups were compared in terms of clinical outcome and complications. The primary outcome measure was the rate of alleviation or disappearance of GOV， and the secondary outcome measure was variceal rebleeding and death. The independent-samples t test was used for comparison of normally distributed or approximately normally distributed quantitative data between two groups， and the Wilcoxon non-parametric test was used for comparison of non-normally distributed quantitative data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of qualitative data between two groups. ResultsThere were 50 patients in the PCSS group， among whom 1 patient was lost to follow-up， and there were 50 patients in the traditional endoscopy group， among whom 3 patients were lost to follow-up. There were no significant differences between the two groups in baseline data such as age， sex， Child-Pugh class， varices grade， and GOV typing （all P>0.05）. Compared with the traditional endoscopy group， the PCSS group had significantly better results of the number of endoscopic treatment sessions （t=-15.671， P=0.001）， the total amount of tissue adhesive used （t=-2.830， P=0.006）， and the rate of alleviation or eradication of varices sclerosis （χ²=7.078， P=0.029）. Both groups had low rates of postoperative rebleeding， adverse reactions， and complications， and there were no significant differences between the two groups （all P>0.05）. ConclusionCompared with traditional endoscopy， PCSS can significantly enhance treatment outcome while maintaining safety standards.

ObjectiveTo investigate the safety and efficacy of endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips in the treatment of cirrhotic patients with gastric varices and gastric-renal shunt （GRS）. MethodsThe patients who attended Beijing Ditan Hospital， Capital Medical University， due to liver cirrhosis and gastric varices from February to June 2023 were enrolled， and all patients were confirmed to have GRS and received endoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips. The primary evaluation index was alleviation or disappearance of varicose veins after surgery， and the secondary evaluation indices were surgical completion and complications. ResultsA total of 11 patients were enrolled in this study， among whom there were 7 male patients and 4 female patients， with a median age of 55 years. Of all patients， 1 had Child class A liver function， 7 had Child class B liver function， and 3 had Child class C liver function. The maximum （median） diameter of the shunt was 8 mm， and the minimum （median） diameter of the shunt was 4 mm. The median blood flow velocity of the target vessel was 11 cm/s before treatment and 5 cm/s after occlusion with metal clips. The median amount of tissue adhesive injected was 2 mL， and the amount of lauromacrogol used was 1 mL. Disappearance of blood flow signals was observed in all patients after surgery （100%）， and the success rate of surgery was 100%. No patient experienced rebleeding after follow-up for 6 weeks. Gastroscopy at 1 month after surgery showed that gastric varices were eradicated or almost disappeared in 9 patients and were alleviated in 2 patients. ConclusionEndoscopic ultrasound-guided tissue adhesive injection with the assistance of metal clips is a feasible， safe， and effective treatment method for cirrhotic patients with gastric varices and GRS.

Background Exposure to perfluoroalkyl and polyfluoroalkyl substances (PFAS) during pregnancy might affect thyroid-related hormone levels in pregnant women. However, most previous studies focused on the effects of PFAS containing 8-10 carbon atoms, and few studies have estimated the associations between PFAS with longer carbon chain and thyroid-related hormone levels. Objective To examine the associations between PFAS exposure and thyroid-related hormones in pregnant women. Methods The present study was based on the Jiashan Birth Cohort from September 2016 to April 2018. We analyzed 13 PFAS in maternal blood samples (n=781) by high-performance liquid chromatography-tandem mass spectrometry, as well as total triiodothyronine (T3), total thyroxine (T4), free T3 (FT3), free T4 (FT4), thyroid stimulating hormone (TSH), thyroglobulin antibody (TG-Ab), and thyroid peroxidase antibody (TPOAb) by electrochemiluminescence immunoassay. PFAS were divided into three groups:low concentration, medium concentration and high concentration according to the tertile of their concentrations. We estimated the associations between PFAS concentrations and thyroid-related hormones in pregnant women by multiple linear regression. Results In the multiple linear regression models, a change in perfluorododecanoic acid (PFDoA) concentrations from the low concentration group to the high concentration group was associated with a −0.10 (95%CI: −0.20, 0) nmol·L⁻¹ change in T3, −0.15 (95%CI: −0.28, −0.02) pmol·L⁻¹ change in FT3, and −3.02 (95%CI: −5.66, −0.39) pmol·L⁻¹ change in FT4, respectively. A change in perfluorotridecanoic acid (PFTrDA) concentrations from the low concentration group to the high concentration group was associated with a −0.10 (95%CI: −0.20, 0) nmol·L⁻¹ change in T3. Compared with the low concentration group, the concentration of T4 in the medium concentration group of perfluorohexane sulfonate (PFHxS) increased by 6.10 (95%CI: 0.44, 11.75) nmol·L⁻¹. No statistically significant associations were found between PFAS and TSH concentration. The negative associations of PFAS with thyroid-related hormones were more pronounced in pregnant women with positive TG-Ab and/or TPOAb. Conclusion Exposure to PFAS during pregnancy may affect thyroid-related hormone homeostasis in pregnant women, and the effect is stronger in TG-Ab and/or TPOAb-positive pregnant women.

Objective To analyze the rebleeding rate in hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) after endoscopic treatment of esophagogastric variceal bleeding and then assessed the risk factors of the rebleeding in the patients. Methods This study retrospectively recruited 169 hepatitis B-associated HCC patients complicated with PVTT and esophagogastric variceal bleeding treated by endoscopy in Department of Gastroenterology, Beijing Ditan Hospital from September 2008 to December 2016. Among them, 47 patients had PVTT Ⅱ, 67 patients had PVTT Ⅲ, and 55 patients had PVTT Ⅳ. Their clinicopathological and follow-up data were retrieved from the medical records and statistically analyzed. Continuous data were compared among groups using ANOVA or Kruskal-Wallis H test. Categorial data were compared among groups using Chi-square test or corrected Fisher test. The Kaplan-Meier curves and Log-rank test were performed to analyze the rebleeding rate and cumulative survival rates after treatment. The univariate multivariate Cox regression analyses were used to identify the risk factors affecting the rebleeding of patients. Results Compared with PVTT Ⅱ and Ⅲ, PVTT Ⅳ patients had a higher serum level of the direct bilirubin ( Z =6.153, P =0.046). The endoscopy treatment successfully blocked esophagogastric variceal bleeding in all patients. There was no significant difference in the rebleeding rates within six months and a year after the treatment (all P > 0.05). It was also no statistically significant difference in cumulative survival rates in six months and l-, 2-, and 3-year after the treatment in PVTT Ⅱ, Ⅲ, and Ⅳ patients (all P > 0.05). Cox multivariate regression analysis showed that hepatic encephalopathy ( HR =3.643, 95% CI : 2.099-6.325, P < 0.001), γ-glutamyltransferase ( HR =1.002, 95% CI : 1.000-1.005, P =0.029), AFP ( HR =1.000, 95% CI : 1.000-1.000, P =0.002) and numbers of tumor lesions ( HR =1.647, 95% CI : 1.011-2.684, P =0.045) were all independent risk factors for 1-year rebleeding in these PVTT patients with esophagogastric variceal bleeding after endoscopic treatment. Conclusion Endoscopic hemostasis is a feasible treatment option for HCC patients with PVTT and esophagogastric variceal bleeding. However, there was no significant difference in the rebleeding and cumulative survival rates in these patients. Furthermore, hepatic encephalopathy, γ-glutamyltransferase, AFP and numbers of tumor lesions were all independent risk factors for 1-year rebleeding in these patients.

Objective To investigate the rebleeding rate after endoscopic selective variceal devascularization (ESVD) and the predictive factors for rebleeding in patients with hepatitis B cirrhosis and esophageal variceal bleeding (EVB). Methods The patients with hepatitis B cirrhosis and EVB who attended Beijing Ditan Hospital, Capital Medical University, from October 2010 to December 2019 and underwent ESVD for the first time were enrolled, and a total of 442 patients were screened out based on inclusion and exclusion criteria. Routine clinical indices, laboratory markers, imaging findings, and endoscopic findings were compared between patients, and the patients were followed up to observe rebleeding. The t -test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier method was used to describe rebleeding and survival status, and a Cox regression analysis was used to determine the independent risk factors for variceal rebleeding. Results The 1-, 2-, 3-, 4-, and 5-year cumulative rebleeding rates after first ESVD treatment were 25.11%, 33.94%, 39.82%, 42.08%, and 45.02%, respectively. The univariate analysis showed that age, systolic pressure, duration of antiviral therapy ≥1 year, ascites, white blood cell count, neutrophil, and direct bilirubin were associated with rebleeding (all P < 0.05), and the multivariate analysis showed that duration of antiviral therapy ≥1 year (hazard ratio [ HR ]=0.504, 95% confidence interval [ CI ]: 0.357-0.711, P < 0.001) and ascites ( HR =1.424, 95% CI : 1.184-1.714, P < 0.001) were independent influencing factors for variceal rebleeding. Conclusion ESVD has a low rebleeding rate in the treatment of hepatitis B cirrhosis with EVB, and presence of ascites and a short duration of antiviral therapy are independent risk factors for rebleeding after treatment.

Objective: To systematically review the barriers and facilitators affecting the implementation of clinical pathways for the clinical pathways. Methods: PubMed, Embase, CNKI, CBM, Wanfang, Cvip databases were searched to collect articles about clinical pathways implementation barriers and facilitators from inception to January 4th, 2019. The tool of confidence in the evidence from reviews of qualitative research(CERQual)was used to grade the confidence of each study. Results: A total of 43 articles from 12 countries were included.There were 8 main categories and 31 subcategories of the barriers about clinical pathways, including content of the clinical pathways, negative outcomes of clinical pathways, physicians knowledge, physicians attitude, resource availability, implementation of activities, patients factors and social factors. The first three barriers of high confidence were lacking of time, capital, equipment, staff and other resources(15 articles, 34.9%), increasing workload(14 articles, 32.6%), unrecognizing pathways(12 articles, 27.9%). There were 6 main categories and 28 subcategories of the facilitators about clinical pathways, including pathways content related, physician related, resource factor and implementation activity. The first three facilitators of high confidence were communication, education and training(25 articles, 58.1%), supporting from managers and colleagues(21 articles, 48.8%)and establishing a clinical pathway facilitation committee(17 articles, 39.5%). Conclusions The successful implementation of clinical pathways connects with its development process, aftereffect evaluation and feedback. It will be implemented effectively only by the completely and environmentally acceptable pathways design, adequate resources, effective organizational activities, continuous audit, evaluation and feedback and physicians active cooperation.
