OBJECTIVE To study the effects of bergapten in the treatment of liver fibrosis and its mechanism based on serum metabolomics. METHODS Forty mice were divided into normal control group (0.5% carboxymethyl cellulose sodium solution), model group (0.5% carboxymethyl cellulose sodium solution), and BP low-dose and high-dose groups (50, 100 mg/kg), with 10 mice in each group. Except for the normal control group, the other three groups were all treated with carbon tetrachloride to induce liver fibrosis model; they were given relevant medicine/solution intragastrically, once a day, for consecutive 8 weeks. After the last medication, the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum were detected, and liver pathological changes were observed; the expressions of α-smooth muscle actin (α-SMA) and Collagen Ⅰ were detected in liver tissue; the serum of the mice was collected for metabolomics analysis. RESULTS Compared with the model group, serum levels of ALT and AST and protein expressions of α-SMA and Collagen Ⅰ in liver tissue were decreased significantly in BP high-dose and low-dose groups (P<0.05), while liver fibrosis was improved significantly. Meanwhile, metabolomics analyses showed that there were a total of 175 serum differential metabolites in the BP high-dose group and model group, of which 18 substances were upregulated and 157 substances were downregulated; the main metabolic pathways involved in bergapten intervention were pyrimidine metabolism, butanoate metabolism, fatty acid synthesis, tyrosine metabolism, β-alanine metabolism, nicotinic acid and nicotinamide metabolism, glutathione metabolism, etc. CONCLUSIONS BP is effective in the treatment of liver fibrosis by regulating pyrimidine metabolism, butanoate metabolism, glutathione metabolism and so on in rats with liver fibrosis.

Objective To assess with machine learning the predictive value of mechanomics derived from coronary CT angiography(CCTA)for atherosclerotic plaque formation in regions proximal to myocardial bridging(MB)in the left anterior descending coronary artery(LAD).Methods This retrospective study included a cohort of patients with MB in LAD and no atherosclerotic plaque formation in LAD as confirmed by two CCTA conducted between January 2007 and April 2021 at our hospital.The interval between the two CCTA examinations was more than 3 months.The primary endpoint was the formation of atherosclerotic plaques in regions proximal to the myocardial bridging.Patient demographic characteristics and clinical risk factors were documented.Then,the patients were matched by age and sex in a 1-to-1 ratio and divided into two groups,those with plaque formation and those without plaque formation.Computational fluid dynamics analysis was performed based on CCTA.Key anatomical parameters of MB,including location,length,depth,and systolic compression index,were meticulously measured on the CCTA images.Mechanomic data were extracted from the region proximal to the MB.A multivariate Cox regression analysis was performed to identify significant features.A random forest algorithm was used to select mechanomic features for subsequent modeling and to assign scores for each patient's mechanomic features.The log-rank test and Kaplan-Meier curves were used to investigate the mechanomic model's predictive performance concerning plaque formation.Additionally,the operator characteristic curves were applied to evaluate how well the model could predict plaque formation across various myocardial bridge subgroups.Results A total of 104 patients with LAD MB were recruited.The mean age of the subjects were(54.56±10.56)years and 75.00%(78/104)of them were male.Among them,52 developed plaque formation over a median follow-up period of 3.0 years.Apart from a smoking history,which was more prevalent in the group with plaque formation than that in the group without plaque formation(21.15%vs.5.77%,P=0.04),no significant differences between the groups were observed in terms of the other clinical or anatomical characteristics(all P≤0.05).The participants were divided into a training set(n=74)and a validation set(n=30)at a 7∶3 ratio.With the mechanomics model constructed using the random forest algorithm,the patients were classified into a high-score group(≥0.46)and a low-score group(<0.46)based on a cutoff score of 0.46.The mechanomics model achieved a sensitivity of 0.87(0.58-0.98)and an accuracy of 0.63(0.44-0.79)in the validation set.The multivariate Cox regression model revealed a strong positive association between mechanomics and plaque formation(hazards ratio[HR]:10.58;95%confidence interval[CI]:3.23-34.64,P<0.001).The log-rank test showed that the high-score group in the mechanomics model was more likely to develop plaques at the proximal regions of the myocardial bridge compared to the low-score group(P<0.001).The area under the curve(AUC)for plaque formation,as predicted by the model,was 0.88(95%CI:0.82-0.95)for the entire population,0.89(95%CI:0.82-0.96)for the training set,0.86(95%CI:0.74-0.99)for the validation set,0.92(95%CI:0.86-0.97)for the superficial MB group,0.86(95%CI:0.74-0.98)for the long MB group,and 0.91(95%CI:0.83-0.98)for the short MB group.Conclusion The mechanomic assessment holds substantial potential as a predictive tool for atherosclerotic plaque formation in regions proximal to MB in LAD.

Objective:To investigate the clinicopathological features, differential diagnosis, treatment and prognosis of undifferentiated embryonal sarcoma of the liver (UESL).Methods:Five UESL cases operated on at Hunan Provincial People's Hospital from 2014 to 2021 were retrospectively analyzed. H&E and immunohistochemical staining were done for pathological observation.Results:The 5 UESL patients(two boys,three girls) were 0.5 to 15 years old, all underwent radical surgical resection. In 3 cases tumors located in right liver, 1 in left liver, 1 in both lobes. Radiographically and visually, the tumor is a large cystic solid mass, microscopically composed of myxoid stroma and undifferentiated stromal cells, with pleomorphic tumor giant cells and characteristic eosinophilic bodies. All 5 patients are now alive after surgical resection: 1 patient achieved disease-free survival of more than 91 months after surgery alone. Two patients had recurrence after surgery and received surgical resection plus chemotherapy or chemotherapy alone. They achieved survival of more than 35 and 16 months, respectively. Two patients were treated with chemotherapy or chemotherapy plus radiotherapy after surgery and survived more than 49 and 31 months without recurrence, respectively.Conclusions:UESL is a rare and highly malignant mesenchymal tumor with characteristic pathologic morphology. Radical resection is the key to the treatment for UESL, and chemotherapy and radiotherapy should be carried out after surgery.
