Taurine attenuates activation of hepatic stellate cells by inhibiting autophagy and inducing ferroptosis.

BACKGROUND: Liver fibrosis is a compensatory response during the tissue repair process in chronic liver injury, and finally leads to liver cirrhosis or even hepatocellular carcinoma. The pathogenesis of hepatic fibrosis is associated with the progressive accumulation of activated hepatic stellate cells (HSCs), which can transdifferentiate into myofibroblasts to produce an excess of the extracellular matrix (ECM). Myofibroblasts are the main source of the excessive ECM responsible for hepatic fibrosis. Therefore, activated hepatic stellate cells (aHSCs), the principal ECM producing cells in the injured liver, are a promising therapeutic target for the treatment of hepatic fibrosis. AIM: To explore the effect of taurine on aHSC proliferation and the mechanisms involved. METHODS: Human HSCs (LX-2) were randomly divided into five groups: Normal control group, platelet-derived growth factor-BB (PDGF-BB) (20 ng/mL) treated group, and low, medium, and high dosage of taurine (10 mmol/L, 50 mmol/L, and 100 mmol/L, respectively) with PDGF-BB (20 ng/mL) treated group. Cell Counting Kit-8 method was performed to evaluate the effect of taurine on the viability of aHSCs. Enzyme-linked immunosorbent assay was used to estimate the effect of taurine on the levels of reactive oxygen species (ROS), malondialdehyde, glutathione, and iron concentration. Transmission electron microscopy was applied to observe the effect of taurine on the autophagosomes and ferroptosis features in aHSCs. Quantitative real-time polymerase chain reaction and Western blot analysis were performed to detect the effect of taurine on the expression of α-SMA, Collagen I, Fibronectin 1, LC3B, ATG5, Beclin 1, PTGS2, SLC7A11, and p62. RESULTS: Taurine promoted the death of aHSCs and reduced the deposition of the ECM. Treatment with taurine could alleviate autophagy in HSCs to inhibit their activation, by decreasing autophagosome formation, downregulating LC3B and Beclin 1 protein expression, and upregulating p62 protein expression. Meanwhile, treatment with taurine triggered ferroptosis and ferritinophagy to eliminate aHSCs characterized by iron overload, lipid ROS accumulation, glutathione depletion, and lipid peroxidation. Furthermore, bioinformatics analysis demonstrated that taurine had a direct targeting effect on nuclear receptor coactivator 4, exhibiting the best average binding affinity of -20.99 kcal/mol. CONCLUSION: Taurine exerts therapeutic effects on liver fibrosis via mechanisms that involve inhibition of autophagy and trigger of ferroptosis and ferritinophagy in HSCs to eliminate aHSCs.

Bufalin enhances the anti-proliferative effect of sorafenib on human hepatocellular carcinoma cells through downregulation of ERK.

The purpose of this study was to investigate the effect of bufalin on the anti-proliferative activity of sorafenib in the human hepatocellular carcinoma (HCC) cell lines PLC/PRF/5 and Hep G-2 and to determine the relevant molecular mechanism. Concurrent treatment with sorafenib and bufalin at a fixed ratio (25:1) for 48 h resulted in synergistic growth inhibition in HCC cell lines as determined by CCK-8 cell viability assays. Exposure of both PLC/PRF/5 and Hep G-2 cells to this combination of sorafenib (6.25 µM) and bufalin (50 nM) resulted in noticeable increases in apoptotic cell death, as evidenced by the disruption of mitochondria, compared to treatment with either agent alone. Although both sorafenib (6.25 µM) and bufalin (250 nM) alone inhibited the phosphorylation of ERK, the reduction in pERK was more pronounced in the cells treated with a combination of bufalin (50 nM) and sorafenib (250 nM). Furthermore, the inhibitory effect of bufalin on pERK was blocked by the PI3kinase inhibitor LY294002, suggesting that the reduction in pERK induced by bufalin might be mediated by AKT in these two HCC cell lines. Taken together, the results of our study suggest that bufalin enhances the anti-cancer effects of sorafenib on PLC/PRF/5 and Hep G-2 by contributing to the downregulation of ERK.

Relationship of depression and sleep quality, diseases and general characteristics.

BACKGROUND: Depression is the most common type of depressive disorder. The most common sleep disorder associated with depression is insomnia. Insomnia and depression are closely related. AIM: To investigate the relationship of designed questionnaire items and depression, and analyze the related factors with depression. METHODS: Questionnaire included Patient Health Questionnaire-9 (PHQ-9) and Pittsburgh sleep quality index (PSQI), 12 kinds of diseases, 8 general characteristics, and 20 insomnia characteristics, totally 56 items were filled out by 411 patients enrolled. RESULTS: All the 9 items of PHQ-9, 6 components of PSQI (except sleep duration), education, living situation, exercise, years of insomnia, western medicine treatment, Chinese medicine treatment, psychotherapy, kinds of insomnia, treatment expected to treat insomnia, psychological counseling, habit of 1 h before bed, habit of lunch break, diagnosed depression, coronary heart disease, mental illness showed significant difference between without and with depression group. By univariate analysis and multivariate analysis. The odds ratio of education, exercise, kinds of insomnia, habit of 1 h before bed, diagnosed depression, coronary heart disease (P = 0.01) showed significant difference. Their odds ratios were 0.71 (0.55, 0.93), 2.09 (1.32, 3.31), 0.76 (0.63, 0.91), 0.89 (0.81, 0.98), 0.32 (0.17, 0.60), 0.43 (0.23, 0.79). CONCLUSION: We demonstrated that education, exercise, kinds of insomnia, habit of 1 h before bed, diagnosed depression and coronary heart disease affect the depression.

Predictive role of the monocyte-to-lymphocyte ratio in advanced hepatocellular carcinoma patients receiving anti-PD-1 therapy.

Background: The immune checkpoint inhibitor (ICIs) therapy has been proven effective in a range of solid tumors including hepatocellular carcinoma (HCC), non-small cell lung carcinoma and metastatic melanoma. However, only a subset of approximately 20% of patients shows an objective response to anti-PD-1 therapy in HCC. Furthermore, the response to anti-PD-1 therapy is not correlated with programmed cell death 1 ligand expression in tumor tissue. Therefore, it is urgent to identify a biomarker to predict the response of anti-PD-1 therapy. Methods: This retrospective study was conducted at the Fudan University Shanghai Cancer Center from December 2019 to June 2021. The monocyte-to-lymphocyte ratio (MLR) was analyzed using a receiver operating characteristic (ROC) curve. A Cox regression model and the log-rank test were used to analyze the relationship between the MLR value and the time to progression (TTP). Results: A total of 34 advanced HCC patients were enrolled in this study. The cut-off point for the MLR at baseline was 0.35. Univariate and multivariate Cox regression models showed that the MLR at baseline was significantly correlated with the TTP (P<0.05). Consistent results were found for disease progression. The log-rank test showed that patients in the low MLR group had a longer TTP (P=0.0027). At the time of disease progression, the median TTP in the low and high MLR groups were 33 and 18 weeks, respectively (P=0.0047). Conclusions: The MLR can predict the response to anti-PD-1 therapy, and a high MLR is correlated with a short TTP in anti-PD-1-treated HCC patients.

Combined ablation-chemotherapy versus chemotherapy alone for pancreatic cancer with liver metastasis: a propensity score matching study.

Objectives: To retrospectively assess the efficacy of combined ablation-chemotherapy in comparison to that of chemotherapy alone in patients with liver metastasized pancreatic ductal adenocarcinoma (lmPDAC).Methods: In total 104 patients with hepatic oligo metastasized PDAC were identified; among them, 74 patients underwent combined thermal ablation-chemotherapy, and 30 patients underwent chemotherapy alone. Through propensity score matching, 1:1 matching of the combined ablation-chemotherapy group and chemotherapy group was achieved. The primary endpoint of this study was overall survival (OS). Clinical and tumor-related factors affecting OS were also analyzed through univariate and multivariate analyses using the Cox risk model.Results: For patients treated with combined ablation-chemotherapy, the median OS was 10.77 months, while it was 5.77 months for patients treated with chemotherapy alone (P = 0.011). The survival benefit for patients treated with combined ablation-chemotherapy was still preserved in the matched cohort, with a median OS of 8.17 months compared to 5.77 months in the chemotherapy group. Univariate and multivariate analyses in the matched population also showed treatment with combined ablation-chemotherapy was an independent prognostic factor (P < 0.05).Conclusions: For patients with liver metastases from pancreatic cancer, the combined use of thermal ablation and systemic chemotherapy offers a chance for a better survival outcome.

[Clinical observation of transarterial chemoembolization combined with sorafenib for advanced hepatocellular carcinoma].

OBJECTIVE: To observe the efficacy and side effects of transarterial chemoembolization (TACE) combined with sorafenib for advanced hepatocellular carcinoma (HCC). METHODS: Forty patients with HCC were treated with sorafenib (400 mg bid) after TACE. The efficacy was evaluated according to RECIST 1.1 criteria, and side effects were assessed by NCI CTC 3.0 criteria. RESULTS: Among the forty cases, one case achieved complete remission (CR), seven cases achieved partial remission (PR), nineteen cases achieved stable disease (SD) and thirteen cases had progressive disease (PD). The disease control rate (DCR) was 67.5%. The overall survival time was 1 - 18 months, and 1-year survival rate was 54.0%. The major adverse events were hand-foot skin reaction, diarrhea and thrombocytopenia. CONCLUSION: The combined therapy of TACE and sorafenib is effective and well tolerated for advanced HCC.

Serum lactate dehydrogenase predicts prognosis and correlates with systemic inflammatory response in patients with advanced pancreatic cancer after gemcitabine-based chemotherapy.

Serum lactate dehydrogenase (LDH) concentrations correlate with tumor progression and poor outcome. We evaluated the predictive value of serum LDH level for overall survival (OS) of patients with advanced pancreatic cancer after gemcitabine-based chemotherapy. We retrospectively enrolled 364 patients with locally advanced or metastatic pancreatic adenocarcinoma who were then allocated to training (n = 139) and validation cohorts (n = 225). We evaluated the association between serum LDH levels and OS as well as with markers of systemic inflammation, including neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and lymphocyte/monocyte ratio (LMR). Kaplan-Meier analyses revealed that low serum LDH levels in the training cohort significantly correlated with longer OS. Multivariate analysis identified the serum LDH levels as an independent prognostic predictor of OS (p = 0.005). Serum LDH levels correlated positively with NLR and PLR and correlated negatively with LMR. Similar results were obtained for the validation cohort, except that multivariate analysis identified the serum LDH level as a significant prognostic predictor and only a statistical trend for OS (p = 0.059). We conclude that serum LDH levels were associated with the systemic inflammatory response and served as a significant prognostic predictor of OS. Serum LDH levels predicted OS in patients with advanced pancreatic cancer after gemcitabine-based palliative chemotherapy.

A retrospective analysis of survival factors of high intensity focused ultrasound (HIFU) treatment for unresectable pancreatic cancer.

OBJECTIVE: To retrospectively evaluate possible impact factors of HIFU treatment outcome for unresectable pancreatic cancer patients. PATIENTS AND METHODS: A total of 689 patients with unresectable pancreatic cancer were recruited in our center from December 30, 2007 to January 30, 2015. 436 patients with unresectable pancreatic cancers received HIFU treatment; the other 253 patients received non-HIFU treatment. Among these 436 patients, 345 patients received a one-time HIFU treatment, 91 patients received HIFU treatment from 2 to 5 times in the same pancreatic mass; 89 patients received HIFU treatment alone; 347 patients received HIFU-based combined therapies. Complications and overall survivals (OS) data in each group were collected. RESULTS: The median overall survivals (mOS) in HIFU group and non-HIFU group were 7.1 vs. 5 months (P=0.005): 9.3 vs. 7.3 months (P=0.202) for patients with stage II disease, 8.3 vs. 7.3 months (P=0.783) for patients with stage III disease, and 6.4 vs. 4.2 months (P<0.0001) for patients with stage IV disease, respectively. Furthermore, there was a significant difference between repeated HIFU and one-time HIFU (mOS: 8.6 vs. 6.8 months, P=0.011). Time of HIFU treatment (P=0.0027), chemotherapy (P<0.0001), radiotherapy (P=0.0006), regional intra-arterial chemotherapy (RIAC) (P<0.0001), and stage (P<0.0001) were independent prognostic factors for the patients who received HIFU treatment. Cox analysis on the relative risk of prognostic factors showed that repeated HIFU vs. one-time HIFU (HR=0.729: 95% CI=0.576-0.924), chemotherapy vs. non-chemotherapy (HR=0.664: 95% CI=0.576-0.766), radiotherapy vs. non-radiotherapy (HR=0.580: 95% CI=0.427-0.789), RIAC vs. non-RIAC (HR=0.737: 95% CI=0.648-0.837), and stage (HR=1.386, 95% CI=1.187-1.619) were associated with significantly inferior survival. Overall, adverse events occurred in 23.2% (101/436) in the HIFU group, which included increase of serum or urinary amylase levels, incomplete intestinal obstruction, mild fever, etc. There were no severe adverse events such as skin burns or GI perforation related to HIFU therapy in any of the patients treated. CONCLUSION: This retrospective analysis revealed that the use of a multimodal treatment approach (the combined therapy of HIFU, RIAC, and chemotherapy, with or without radiotherapy) could improve survival of patients with unresectable pancreatic cancer, and repeated HIFU presented a survival benefit and did not increase risk.

Effectiveness and complications of ultrasound guided fine needle aspiration for primary liver cancer in a Chinese population with serum α-fetoprotein levels ≤200 ng/ml--a study based on 4,312 patients.

BACKGROUND: Hepatocellular carcinoma (HCC) can be diagnosed by noninvasive approaches with serum α-fetoprotein (AFP) levels >200 ng/ml and/or a radiological imaging study of tumor mass >2 cm in patients with chronic liver disease. Percutaneous fine needle aspiration (FNA) under ultrasound (US) guidance has a diagnostic specificity of 95% and is superior to radiological imaging studies. AIM: The aim of this study is to elucidate the effectiveness and complications of fine needle aspiration in a Chinese population with primary liver cancer and AFP levels ≤200 ng/ml. MATERIALS AND METHODS: A retrospective study was conducted over a period of 28 years. This selection period included patients with a suspected diagnosis of primary liver cancer whose AFP levels were ≤200 ng/ml and who underwent US-FNA. This data was then analyzed with cytomorphological features correlating with medical history, radiological imaging, AFP, and follow-up information. RESULTS: Of the 1,929 cases with AFP ≤200 mg/ml, 1,756 underwent FNA. Of these, 1,590 cases were determined malignant and the remaining 166 were determined benign. Further, 1,478 malignant cases were diagnosed by FNA alone, and of these, 1,138 were diagnosed as PLC. The sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of the diagnoses were 92.96%, 100%, 100%, 59.71%, and 93.62% respectively. There was no significant difference in the sensitivity, specificity, PPV and NPV between the subgroups with tumor size<2 cm and ≥2 cm. Major complications included implantation metastasis and hemorrhage. CONCLUSION: Patients with PLC, especially those who present with an AFP ≤200 ng/ml, should undergo FNA. If negative results are obtained by FNA, it still could be HCC and repeated FNA procedure may be needed if highly suspicious of HCC on imaging study. The superiority of FNA in overall accuracy may outweigh its potential complications, such like hemorrhage and implantation metastasis.
