LncRNA DDX11-AS1 accelerates hepatocellular carcinoma progression via the miR-195-5p/MACC1 pathway.

INTRODUCTION AND AIM: Long non-coding RNA (lncRNA) has been shown to be a vital regulator of cancer progression, including hepatocellular carcinoma (HCC). However, the role of DEAD/H box protein 11 antisense RNA 1 (DDX11-AS1) in HCC remains to be further studied. MATERIAL AND METHODS: The expression levels of DDX11-AS1, miR-195-5p and metastasis-associated in colon cancer-1 (MACC1) were determined by quantitative real-time PCR (qRT-PCR). Cell counting kit-8 (CCK-8), transwell and apoptosis determination assays were used to evaluate cell proliferation, migration, invasion and apoptosis, respectively. Mice xenograft models were constructed to verify the effect of DDX11-AS1 on HCC tumor growth in vivo. Furthermore, lactate production, glucose consumption, ATP level and glucose uptake were detected to assess cell glucose metabolism. The interactions among DDX11-AS1, miR-195-5p and MACC1 were verified by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. Moreover, western blot (WB) analysis was performed to evaluate the protein levels. RESULTS: DDX11-AS1 was upregulated in HCC tissues and cells, and its silencing could inhibit HCC cell proliferation, migration, invasion and glucose metabolism, and promote apoptosis in vitro. Also, DDX11-AS1 knockdown reduced HCC tumor growth in vivo. Besides, DDX11-AS1 could interact with miR-195-5p, and miR-195-5p inhibitor reversed the inhibitory effect of silenced DDX11-AS1 on HCC cell progression. In addition, MACC1 was a target of miR-195-5p, and its overexpression reversed the suppression effect of miR-195-5p on HCC cell progression. CONCLUSION: Our data revealed that DDX11-AS1 could act as an oncogenic regulator in HCC, providing a potential therapeutic target for HCC treatment.

A comparative study on postoperative mortality prediction of SFLI scoring system and Child-Pugh classification in patients with hepatocellular carcinoma.

PURPOSE: In our previous study, we have established the clinical significance of the SFLI (scoring formula of liver injury), the purpose of this study was to compare the SFLI system and the Child-Pugh grading system in the prediction of postoperative mortality in patients with hepatocellular carcinoma (HCC). METHODS: 114 patients with HCC who underwent surgical treatment were enrolled. According to the requirement of the indicators for the Child-Pugh classification, various indices (including albumin [ALB], total bilirubin [TBIL], prothrombin time [PT], ascites, and hepatic encephalopathy) were considered in these patients before surgery, and then Child-Pugh grading was performed. Similarly, the serum biochemical markers including ALB, pre-albumin (PA), TBIL, serum creatining (SCR), international normalized ratio (INR), alanine transminase (ALT), aspartate transaminase (AST), γ-glutamyl transpeptidase (ggr;-GT), alkaline phosphatase (ALP), PT, activated partial thromboplastin time (APTT), and thrombine time (TT) were collected before surgery for SFLI analysis. The predicted postoperative mortality rates of these two scoring models and their diagnostic efficacy were analyzed and compared. RESULTS: According to the Child-Pugh grading system, in level A, B and C were 75, 35, and 4 cases respectively, and the corresponding mortality rates were 1.3% (1/75), 17.1% (6/35) and 75% (3/4). Meanwhile, according to the SLFI classification, the number of patients in the grade I, I+, II, and III were 36, 29, 28, and 21, respectively, and the corresponding mortality rates were 0, 0, 14.3% (4/28), and 28.6% (6/21), respectively. The patient mortality rate increased significantly with increasing grading (p<0.01). These two classification methods were further compared using ROC analysis, in which the area under the curve (AUC) for the Child-Pugh method was 10.2% with a 95% confidence interval (95% CI) 17-18, and the AUC of SFLI was 88.2% with a 95% CI 80-96. CONCLUSION: The SFLI scoring system is very useful in the assessment of liver function and postoperative mortality, and its grading standard is much better than the traditional Child-Pugh classification in many aspects.

Development of a predictive nomogram for in-hospital death risk in multimorbid patients with hepatocellular carcinoma undergoing Palliative Locoregional Therapy.

Patients diagnosed with hepatocellular carcinoma (HCC) often present with multimorbidity, significantly contributing to adverse outcomes, particularly in-hospital mortality. This study aimed to develop a predictive nomogram to assess the impact of comorbidities on in-hospital mortality risk in HCC patients undergoing palliative locoregional therapy. We retrospectively analyzed data from 345 hospitalized HCC patients who underwent palliative locoregional therapy between January 2015 and December 2022. The nomogram was constructed using independent risk factors such as length of stay (LOS), hepatitis B virus (HBV) infection, hypertension, chronic obstructive pulmonary disease (COPD), anemia, thrombocytopenia, liver cirrhosis, hepatic encephalopathy (HE), N stage, and microvascular invasion. The model demonstrated high predictive accuracy with an AUC of 0.908 (95% CI: 0.859-0.956) for the overall dataset, 0.926 (95% CI: 0.883-0.968) for the training set, and 0.862 (95% CI: 0.728-0.994) for the validation set. Calibration curves indicated a strong correlation between predicted and observed outcomes, validated by statistical tests. Decision curve analysis (DCA) and clinical impact curves (CIC) confirmed the model's clinical utility in predicting in-hospital mortality. This nomogram offers a practical tool for personalized risk assessment in HCC patients undergoing palliative locoregional therapy, facilitating informed clinical decision-making and improving patient management.

Primary hepatic lymphoma a case report and literature review.

RATIONALE: Primary hepatic lymphoma is a rare extranodal non-Hodgkin lymphoma that is primarily localized in the liver. It predominantly affects elderly males and presents with nonspecific laboratory findings, imaging results, and clinical symptoms, making diagnosis challenging. Histopathological examination serves as the gold standard for diagnosis, and treatment options include chemotherapy or surgical intervention combined with chemotherapy. PATIENT CONCERNS: A 50-year-old male patient came to our hospital for treatment after finding a mass in his liver. DIAGNOSES: Laboratory tests and clinical symptoms lack specificity for primary hepatic lymphoma, and imaging findings can be difficult to differentiate. Pathology is the gold standard. OUTCOMES: The patient was dead. CONCLUSION: A definitive diagnosis primarily relies on histopathological examination, and surgical resection combined with chemotherapy yields better treatment outcomes.

A nomogram for predicting risk of death during hospitalization in elderly patients with Alzheimer's disease at the time of admission.

Background and objectives: Elderly patients with Alzheimer's disease (AD) often have multiple underlying disorders that lead to frequent hospital admissions and are associated with adverse outcomes such as in-hospital mortality. The aim of our study was to develop a nomogram to be used at hospital admission for predicting the risk of death in patients with AD during hospitalization. Methods: We established a prediction model based on a dataset of 328 patients hospitalized with AD -who were admitted and discharged from January 2015 to December 2020. A multivariate logistic regression analysis method combined with a minimum absolute contraction and selection operator regression model was used to establish the prediction model. The identification, calibration, and clinical usefulness of the predictive model were evaluated using the C-index, calibration diagram, and decision curve analysis. Internal validation was evaluated using bootstrapping. Results: The independent risk factors included in our nomogram were diabetes, coronary heart disease (CHD), heart failure, hypotension, chronic obstructive pulmonary disease (COPD), cerebral infarction, chronic kidney disease (CKD), anemia, activities of daily living (ADL) and systolic blood pressure (SBP). The C-index and AUC of the model were both 0.954 (95% CI: 0.929-0.978), suggesting that the model had accurate discrimination ability and calibration. Internal validation achieved a good C-index of 0.940. Conclusion: The nomogram including the comorbidities (i.e., diabetes, CHD, heart failure, hypotension, COPD, cerebral infarction, anemia and CKD), ADL and SBP can be conveniently used to facilitate individualized identification of risk of death during hospitalization in patients with AD.

S100 family members: potential therapeutic target in patients with hepatocellular carcinoma: A STROBE study.

ABSTRACT: Proteins in S100 family exhibit different expressions patterns and perform different cytological functions, playing substantial roles in certain cancers, carcinogenesis, and disease progression. However, the expression and role of S100 family members in the prognosis of hepatocellular carcinoma (HCC) remains unclear. To investigate the effect of S100 family members for the prognosis of liver cancer, we assessed overall survival (OS) using a Kaplan-Meier plotter (KM plotter) in liver cancer patients with different situation. Our results showed that 15 members of the S100 family exhibited high levels of expression and these levels were correlated with OS in liver cancer patients. The higher expression of S100A5, S100A7, S100A7A, S100A12, S100Z, and S100G was reflected with better survival in liver cancer patients. However, worse prognosis was related to higher levels of expression of S100A2, S100A6, S100A8, S100A9, S100A10, S100A11, S10013, S100A14, and S100P. We then evaluated the prognostic values of S100 family members expression for evaluating different stages of AJCC-T, vascular invasion, alcohol consumption, and the presence of hepatitis virus in liver cancer patients. Lastly, we studied the prognostic values of S100 family members expression for patients after sorafenib treatment. In conclusion, our findings show that the proteins of S100 family members exhibit differential expression and may be useful as targets for liver cancer, facilitating novel diagnostic and therapeutic strategies in cancer.

Preoperative evaluation of the degree of liver fibrosis based on matter-element analysis using serological indicators in patients with hepatocellular carcinoma.

Evaluation of the degree of liver fibrosis is an important basis for the clinical diagnosis and treatment of patients with hepatocellular carcinoma (HCC). It is meaningful to make a preoperative evaluation with non-invasive methods. In the current study, 12 commonly used preoperative serological indicators from 161 HCC patients with different degree of liver fibrosis were collected retrospectively, and 8 of the indicators (ALB, PA, TBil, INR, AST, GGT, ALP, and PT) were ultimately used in matter-element analysis to create a formula. The relationship between those results and the histological sub-classification of the Laennec liver fibrosis scoring system was analyzed. The calculated value of R from this formula will indicate the differing degree of liver fibrosis in a patient: i) the value of 0.802 ≤ R < 1 indicates the early stage of liver cirrhosis, which corresponds to Laennec stages 0-3; ii) the value of 0.752 ≤ R < 0.802 indicates the mild stage of liver cirrhosis, which corresponds to Laennec stage 4A; iii) the value of 0.698 ≤ R < 0.752 indicates the moderate stage of liver cirrhosis, which corresponds to Laennec stage 4B; and iv) the value of 0.444 ≤ R < 0.698 indicates the severe stage of liver cirrhosis, which corresponds to Laennec stage 4C. The hope is that this formula for preoperative evaluation of the degree of liver fibrosis using non-invasive methods would be useful in the clinical diagnosis and treatment of patients with HCC in the future.

VX680 suppresses the growth of HepG2 cells and enhances the chemosensitivity to cisplatin.

VX680 is an Aurora A inhibitor. It has been reported to inhibit the growth of the HepG2 cell line in several studies. However, whether it enhances chemosensitivity to cisplatin remains unclear. In this study, the synergistic effect of VX680 and cisplatin on the proliferation of HepG2 cells was determined by MTT assay. The changes in cell apoptosis were detected by flow cytometry. Aurora A, Bcl-2 and p53 protein levels were analyzed by western blotting. This study demonstrated that VX680, cisplatin and a combination of the two inhibit the growth of HepG2 cells in a dose- and time-dependent manner. A synergistic effect was observed with the combined therapy. Moreover, the inhibitory effect of VX680 was positively correlated with the expression of Aurora A. The rate of apoptosis in the combined group was significantly higher compared with that of the VX680 and cisplatin groups. In addition, VX680 and cisplatin increased the expression of the p53 protein. Cisplatin reduced the expression of Bcl-2 protein, while VX680 did not. In the combined group, the expression of Bcl-2 and p53 changed significantly compared with the single drug group and control group. This study suggests that Aurora A may represent a valid target in hepatocellular carcinoma. We also demonstrated that the Aurora A inhibitor VX680 has a synergistic effect with cisplatin.
