Objective:To investigate the predictive ability of Glypican-3 (GPC3) positive hepatocellular carcinoma based on the hepatobiliary specific contrast agent gadoxetate disodium enhancement of the liver imaging reporting and data system version 2018 (LI-RADS v2018) imaging features, and to assess the relevant clinical imaging features for postoperative recurrence in GPC3 positive HCC patients.Methods:This study was a cohort study. A total of 122 hepatocellular carcinoma patients who underwent gadoxetate disodium enhanced MRI examination with hepatic tumor resection in Henan Provincial People′s Hospital from January 2017 to December 2021 were retrospectively collected, including 96 GPC3 positive and 26 GPC3 negative patients. The imaging features defined by LI-RADS v2018 of HCC lesions were analyzed. Patients were followed up for 40 months to determine recurrence free survival (RFS). The logistic regression was used to analyze the risk factors of GPC3 positivity. An imaging model, and a clinical-imaging model which combined the patient′s alpha-fetoprotein levels were constructed. The efficacy of the model for predicting GPC3 positivity was assessed using receiver operating characteristic curves. Kaplan-Meier method was used to draw the survival curve, and the log-rank test was used to compare the RFS between GPC3 positive and negative patients. Risk factors affecting the recurrence of GPC3 positive HCC were assessed by Cox regression.Results:The results of logistic multivariate regression analysis confirmed that rim enhancement ( OR=5.685, 95% CI 1.229-26.287, P=0.026) and irregular tumor margin at hepatobiliary phase ( OR=4.431, 95% CI 1.684-11.663, P=0.003) were independent risk factors for GPC3 positive HCC. The area under the curve for predicting GPC3 positivity was 0.745 (95% CI 0.636-0.854) for the imaging model and 0.776 (95% CI 0.677-0.876) for the clinical-imaging model. The mean RFS in the GPC3 positive group was 22 months, and it was 32 months in the negative group. There was a statistically significant difference in RFS between the two groups ( χ2=5.15, P=0.023). The multivariate Cox regression analysis showed that the arterial rim enhancement ( HR=5.460, 95% CI 1.966-15.162, P=0.001), microvascular invasion ( HR=2.402, 95% CI 1.210-4.769, P=0.012), portal vein tumor thrombus ( HR=3.226, 95% CI 1.114-9.344, P=0.031) were independent risk factors for recurrence after hepatic tumor resection for GPC3-positive HCC. Conclusions:A model based on the LI-RADS v2018 imaging features of hepatobiliary specific contrast agent gadoxetate disodium enhancement can effectively predict GPC3 positive HCC. The arterial rim enhancement, microvascular invasion and portal vein tumor thrombus are independent risk factors for postoperative recurrence of GPC3 positive HCC.

Objective:To explore the composition of oral microbiome in patients of long-term survival after liver transplantation, and compare the diversity and distribution of oral microbiome in liver transplant patients with or without liver cancer.Methods:This is a cross-sectional study. Clinical data of 20 patients of long-term survival after liver transplantation from Beijing Chaoyang Hospital Affiliated to Capital Medical University from July 2023 to October 2023 were continuously collected, including 13 males and 7 females, aged 55 (48, 60) years. There were eight patients with hepatocellular carcinoma (HCC) undergoing liver transplantation and 12 non-HCC liver transplant patients. Oral microbiome was analyzed by 16S rDNA gene sequencing, and the diversity analysis and LEfSe analysis were performed.Results:The top ten groups of bacteria in the HCC and non-HCC liver transplant patients were both Bacteroidota, Firmicutes, Proteobacteria, Actinobacteria, Fusobacteriota, Patescibacteria, Campylobacterota, Cyanobacteria, spirochaetota, and Aenigmarchaeota. The top ten genus levels of bacteria in the HCC and non-HCC liver transplant patients were both Haemophilus, Porphyromonas, Gemella, Fusobacterium, Actinomyces, Prevotella, Rothia, Streptococcus, Neisseria. By LEfSe analysis, we found the enrichment of Flavobacteriales, Flavobacteriaceae, Capnocytophaga, Mogibacterium_timidum, Capnocytophaga_leadbetteri, Campylobacter_showae in the HCC group, while the enrichment of Veillonella_atypica, Prevotella_histicola in the non-HCC group.Conclusion:The main microbiome was similar between HCC and non-HCC liver transplant patients, but there were also some differences in microbiome communities.

Objective:To investigate the effect of lymph node metastasis on the prognosis of patients with G2 phase stage pancreatic neuroendocrine neoplasm(pNEN).Methods:A retrospective case control study was conducted to analyze the case data of 368 patients with pancreatic neuroendocrine tumors in G2 phase stage from January 1, 2010 to December 31, 2016 in SEER database, including 174 males and 194 females. According to whether lymph nodes were metastatic, they are divided into lymph node non metastatic (N0) group ( n=272) and lymph node metastatic (N1) group ( n=96). The Kaplan-Meier method and Log-rank test were used to compare the overall survival rate (OS) of patients in the N0 and N1 groups. The COX proportional risk model was used to evaluate whether N stage was an independent risk factor affecting prognosis. Count data were expressed as cases and percentage(%), and Chi-square test was used for comparison between the groups. Results:Among all patients, the OS of patients in the N0 group was better than that of patients in the N1 group. The OS of N0 patients at 1, 3, and 5 years was 96.3%, 92.7%, and 85.6%, respectively, while the OS of N1 patients at 1, 3, and 5 years was 92.6%, 82.1%, and 82.1%, respectively ( P=0.014). Multivariate analysis showed that age ( HR=2.245, 95% CI: 1.126-4.475, P=0.022) and N stage ( HR=0.457, 95% CI: 0.237-0.883, P=0.020) were independent prognostic factors for G2 phase pNEN patients. Conclusion:Lymph node metastasis is one of the independent prognostic factors in patients with G2 phase stage pNEN.

Objective:To explore the influence of fatty liver donor on the prognosis of benign liver disease liver transplantation.Methods:The clinical data of 229 recipients and donors who underwent liver transplantation at Beijing Chaoyang Hospital affiliated to Capital Medical University from January 2015 to December 2019 due to benign liver diseases were retrospectively analyzed. According to the degree of fatty degeneration of the donor liver, the patients were divided into non-fatty liver group( n=168), mild-medium fatty liver group( n=43), and severe fatty liver group( n=18). First, the overall prognosis after liver transplantation was analyzed, the general data of the donor and recipient were compared, and the perioperative complications of the three groups were compared. Finally, survival analysis was performed to compare the long-term prognosis of the three groups. Measurement data with the normal distribution were represented as ( Mean± SD), comparisons among groups were analyzed using t test. Comparisons of counting data between groups were analyzed using chi-square test. The theoretical frequency was less than 1. Fisher exact probability method was used, and variance analysis was used for the comparison among the multiple groups. Results:The overall 1-year, 3-year, and 5-year survival rates of the patients were 86.9%, 70.7%, 70.7%, respectively, and the average survival time was 53.1 months. The general data of donors and recipients were not significantly different among the three groups. The probability of perioperative transplanted liver failure, delayed liver function recovery, and acute kidney injury in recipients with severe fatty liver was significantly higher than that of mild to moderate fatty liver group and non-fatty liver group ( P<0.05). The results of survival analysis showed that the 1-year, 3-year, and 5-year survival rates of the non-fatty liver group were 90.5%, 71.7%, 71.7%, the mild-moderate group were 88.4%, 76.7%, 64.0% and the severe fatty liver group were 61.1%, 49.4%, 49.4%, the survival rate of patients with severe fatty liver was significantly lower than that of the other two groups ( P<0.05). Conclusion:Donor weight-grade steatosis leads to a higher incidence of transplanted liver failure, delayed liver function recovery, acute kidney injury, and worse long-term prognosis.

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

Objective To analyze the application effect of non-penetrating vascular closure system in portal vein reconstruction of allogenic liver transplantation in adults. Methods Clinical data of 222 patients undergoing allogeneic liver transplantation were retrospectively analyzed. According to whether vascular closure system was used in portal vein reconstruction during operation, all patients were divided into vascular clip group (n=137) and traditional suture group (n=85). Perioperative conditions, clinical prognosis and complications were statistically compared between two groups. Results All patients successfully completed the surgery. The success rate of one-time portal vein anastomosis was 93.4% (128/137) in the vascular clip group. A total of 14 patients died during perioperative period in this study with a mortality rate of 6.3% (14/222). No portal vein-related complications occurred during perioperative period in both groups. The time of portal vein anastomosis in the vascular clip group was (5.6±1.7) min, which was significantly shorter than (10.7±3.6) min in the traditional suture group (P<0.05). The incidence and grade of perioperative complications did not significantly differ between two groups (all P>0.05). Conclusions It is safe and feasible to utilize vascular closure system to reconstruct the portal vein during liver transplantation. Compared with traditional suture, it can effectively shorten the time of portal vein anastomosis.
