RESUMO

BACKGROUND: In the quest to manage hepatocellular carcinoma (HCC), the focus has shifted to a more holistic approach encompassing both data analytics and innovative treatments. Analyzing rich data resources, such as the cancer genome atlas (TCGA), and examining progressive therapies can potentially reshape the trajectory of HCC treatment. AIM: To elucidate the immunological genes and the underlying mechanism of the combined Kombo knife and sorafenib regimen for HCC by analyzing data from TCGA and machine learning data. METHODS: Immune attributes were evaluated via TCGA's postablation HCC RNA sequencing data. Using weighted gene coexpression network analysis and machine learning, we identified genes with high prognostic value. The therapeutic landscape and safety metrics of the integrated treatment were critically evaluated across cellular and animal models. RESULTS: Immune genes-specifically, peptidylprolyl isomerase A and solute carrier family 29 member 3-emerged as significant prognostic markers. Enhanced therapeutic outcomes, such as prolonged progression-free survival and an elevated overall response rate, characterize the combined approach, with peripheral blood mononuclear cells displaying potent effects on HCC dynamics. CONCLUSION: The combination of Kombo knife with sorafenib is an innovative HCC treatment modality anchored in immune-centric strategies.

RESUMO

This study aimed to test cinobufacini therapeutic potential for pancreatic cancer, verify its potential molecular mechanism, and evaluate the cinobufacini impact on pancreatic cancer microenvironment. First, the effect of cinobufacini-treated pancreatic stellate cells (PSCs) supernatant on the value-added ability of pancreatic cancer (PCCs) was tested. The results show that cinobufacini can effectively reduce the ability of PSCs supernatant to promote the value-added PCCs. Further results show that cinobufacini can effectively reduce the concentration of TGFß in the supernatant of PSCs. Subsequently, the impact of cinobufacini on the transcription and translation levels of key genes in the TGFß/Smads pathway was examined. The results showed that the impact of cinobufacini on the transcription levels of Smad2, Smad3, and Smad7 was in a concentration-dependent manner, while the transcriptional activity of collagen I mRNA was decreased with the increase of cinobufacini concentration. The results of protein expression showed that cinobufacini could upregulate the expression of inhibitory protein Smad7, inhibit the phosphorylation level of p-Smad2/3, and then suppress the expression of type I collagen (collagen I). On the one hand, this study shows that cinobufacini can inhibit the promotion of PSCs on the proliferation of PCCs. On the other hand, cinobufacini can upregulate the expression of the inhibitory molecule, Smad7, through the TGFß/Smads pathway and reduce the phosphorylation level of p-Smad2/3, thereby inhibiting the expression of collagen I and pancreatic fibrosis. cinobufacin can inhibit the proliferation of SW1900 cells by blocking the TGFß/Smads pathway of pancreatic stellate cells. These results provide a clinical basis for the treatment of pancreatic cancer.

RESUMO

OBJECTIVE@#To observe the effect of nuclear transcription factor-κB (NF-κB) on cerebral edema in rats with traumatic brain injury (TBI).@*METHODS@#Male SD rats with fluid percussion injury (FPI) were selected. After separation and culture, rats' astrocytes all suffered FPI. The expression of NF-κB and the water content were detected at the animal and cellular levels, while the activity of NOX was evaluated at the cellular level.@*RESULTS@#According to the results, the positive expression of NF-κB and expression of mRNA were significantly increased and the water content was increased for rats after TBI, while NF-κB inhibitor BAY11-7082 could significantly reduce the effect of TBI. 1 and 3 h after FPI of astrocytes, the activation of NF-κB was increased and BAY 11-7082 could significantly improve the injury-induced swelling of astrocytes. After the injury of astrocytes, the activity of NOX was also increased, while BAY 11-7082 could reduce the activity of NOX.@*CONCLUSIONS@#The results show that the activation of NF-κB in astrocytes is a key factor in the process of cerebral edema after TBI of rats.

RESUMO

OBJECTIVE: To observe the clinical effect of the combined therapy using argon-helium cryosurgery (Ar-He knife) and Chinese herbal medicine in treating non-small cell lung cancer (NSCLC). METHODS: Fifty-seven patients of NSCLC were treated with the combined therapy and observed. RESULTS: The treatment was successfully completed in all patients with mild adverse reactions. The effective rate was 83.8% 3 months after the operation, 79.6% 6 months after the operation, and 77.3% 12 months after the operation, with median survival of 9 months. The survival rate after 12 months was 46.67% (21/45), 34.62% (9/26) after 18 months, and 36.36% (4/11) after 24 months. CONCLUSION: Argon-helium cryosurgery therapy is superior in its assured orientation, quick tumor load deprivation and less postoperational reaction. Combined with Chinese herbal medication, Argon-helium cryosurgery therapy can prolong survival time, relieve clinical symptoms, and elevate the quality of life in NSCLC patients, and is thus worthy of promotion.

RESUMO

<p><b>OBJECTIVE</b>To explore the relationship between the patients' high follicle-stimulating hormone (FSH) azoospermia and microdeletions in Y chromosome.</p><p><b>METHODS</b>Eleven sequence tagged sites (STSs) in Yq were detected by PCR in 16 male patients' high FSH azoospermia.</p><p><b>RESULTS</b>Microdeletions were observed in 6 of 16 male patients and the deletion rate was 37.5%(6/16). Five types of microdeletions were detected: AZFc(SY152), AZFc (SY152+SY254)+AZFd (SY153), AZFc (SY152+SY254+SY255)+AZFd (SY153), AZFc (SY152+SY158+SY255)+AZFd (SY153),and AZFb (SY130)+AZFc (SY158+SY254+SY255)+AZFd (SY153) respectively.</p><p><b>CONCLUSION</b>Microdeletion of Y chromosome was one of the important reasons of the patients' high FSH azoospermia. Before the application of assisted-reproductive technology (ART) to the patients, it is necessary to detect the microdeletions, especially AZFc and AZFd.</p>
