Hepatocellular carcinoma­cavernous hemangioma collision tumor: A case report.

Collision tumors consisting of hepatocellular carcinoma (HCC) and cavernous hemangioma (CH) are rare and the clinicopathological characteristics or cause of the tumors remain unclear. The present study reports the case of a 71-year-old male patient who was admitted to Sunshine Union Hospital (Weifang, China) due to a liver mass found during a routine physical examination. computed tomography scans showed a main lesion of ~4.0×4.2×3.5 cm in segment IV of the patient's liver and a nodule of ~2.4×2.2×1.3 cm in the lower-left part of the lesion, which was clearly demarcated from the main lesion. The capsule of the lesion was found to be intact during the operation performed to remove the tumor. The final patient diagnosis was of a HCC-CH collision tumor based on pathology. The patient underwent follow-up for 6 months after surgery and no recurrence was observed.

Safety and immunogenicity of inactivated COVID-19 vaccine CoronaVac and the RBD-dimer-based COVID-19 vaccine ZF2001 in chronic hepatitis B patients.

Background and aims: Although COVID-19 vaccination is recommended for the patients with chronic liver disease, the clinical outcomes of COVID-19 vaccinated in patients with chronic hepatitis B (CHB) has not been well characterized. The study aimed to explore the safety and specific antibody responses following COVID-19 vaccination among CHB patients. Methods: Patients with CHB were included. All patients were vaccinated with two doses of inactivated vaccine (CoronaVac) or three doses of adjuvanted protein subunit vaccine (ZF2001). The adverse events were recorded and neutralizing antibody (NAb) were determined 14 days following the whole-course vaccination. Results: A total of 200 patients with CHB were included. Specific NAb against SARS-CoV-2 were positive in 170 (84.6%) patients. The median (IQR) concentrations of NAb were 16.32 (8.44-34.10) AU/ml. Comparison of immune responses between CoronaVac and ZF2001 vaccines showed no significant differences in neither the concentrations of NAb nor the seropositive rates (84.4 vs. 85.7%). Moreover, we observed lower immunogenicity in older patients and in patients with cirrhosis or underlying comorbidities. The incidences of adverse events were 37 (18.5%) with the most common adverse event as injection side pain [25 (12.5%)], followed by fatigue [15 (7.5%)]. There were no differences in the frequencies of adverse between CoronaVac and ZF2001 (19.3% vs. 17.6%). Almost all of the adverse reactions were mild and self-resolved within a few days after vaccination. Severe adverse events were not observed. Conclusions: COVID-19 vaccines, CoronaVac and ZF2001 had a favorable safety profile and induced efficient immune response in patients with CHB.

Biomedical Analytics of Four Chinese Medicinals in Treatment of Insomnia Based on Network Pharmacology.

Aim: Our aim is to recommend the appropriate Chinese medicinals in clinical treatment of insomnia, which are suanzaorén (Semen Ziziphi Spinosae), chuanxiong (Rhizoma Chuanxiong), fúlíng (Poria), and báisháo (Radix Paeoniae Alba). Method: Based on network pharmacology, the active molecules and mechanism of these four Chinese medicinals treating insomnia were sought and analyzed. The components of the four Chinese medicinals with potential activity were collected and screened. Moreover, the recollected human disease-related targets were correlated through Cytoscape 3.8.2, and the network diagram of drug component disease targets was drawn. Based on the human protein-protein interaction database, the above network diagram was imported to establish the protein-protein interaction (PPI) and composite target pathway (C-T-P) networks. After selecting important information, the pathway analysis was carried out to show the biological process, core target, and core pathway of insomnia treatment. Result: In this study, 44 active components and 81 drug-disease common targets were obtained; 307 key targets were found in the PPI network; a core cluster composed of 14 nodes and 50 functional associations was found. Conclusion: In summary, the four Chinese medicinals' effective components and main mechanism of in the treatment of insomnia may be related to their participation in the regulation of endocrine. Compared with the existing network pharmacological analysis results of SuanZaoRénTang (Sour Jujube Decoction), which is commonly used in insomnia, they have similar effects on the immune system and HPA axis, while the focus of the four Chinese medicinals is mainly on endocrine regulation, and SuanZaoRénTang (Sour Jujube Decoction) is mainly on anti-inflammatory effect.

MiR-27a-3p Targeting GSK3ß Promotes Triple-Negative Breast Cancer Proliferation and Migration Through Wnt/ß-Catenin Pathway.

BACKGROUND: Dysregulation of microRNAs (miRNAs) was found to play crucial roles in varieties of cancers, which affect tumor proliferation and migration. MiR-27a-3p has been identified as a tumor-related miRNA in liver cancer, lung cancer, and colorectal cancer. However, the function of miR-27a-3p in triple-negative breast cancer (TNBC) and its possible molecular mechanisms have still not been elucidated. METHODS: QRT-PCR technique was used to detect the expression of miR-27a-3p in TNBC and normal breast cell lines or the effects of miR-27a-3p knockdown and overexpression in TNBC cell lines. Proliferation and migration were measured by CCK-8 method, colony formation, wound healing, and Transwell assays, respectively. Furthermore, we used a dual-luciferase reporter gene assay and Western blot analysis to identify GSK3ß as a target of miR-27a-3p. RESULTS: In this study, we found that miR-27a-3p expression was significantly elevated in TNBC cell lines. Database analysis suggested that TNBC patients with a high expression of miR-27a-3p have poorer overall survival possibilities. Overexpression of miR-27a-3p promotes TNBC cells proliferation, colony formation, and cell migration in vitro. Nevertheless, dual-luciferase reporter result showed that miR-27a-3p directly targeted the 3'-UTR regions of GSK3ß mRNA and negatively regulated its expression. Lastly, we demonstrated that miR-27a-3p inactivates Wnt/ß-catenin signaling pathway via targeting GSK3ß. CONCLUSION: These results indicate that expression of miR-27a-3p was highly expressed in TNBC and promoted tumor progression through attenuating GSK3ß and may have a potential molecular-targeted strategy for TNBC therapy.
