RESUMO
BACKGROUND AND STUDY AIM: The mechanisms underlying the progression of non-alcoholic fatty liver disease (NAFLD) into hepatocellular carcinoma (HCC) remains confusing and the therapeutics approaches are also challenging. Here, we aimed to investigate the effects of scoparone on the treatment of HCC stemmed from NAFLD and the underlying mechanisms. MATERIALS AND METHODS: A model of NAFLD-HCC was created in mice, and these mice were treated with scoparone. Biochemical assays were conducted to assess the levels of biochemical markers. Tumors were evaluated through morphological examination. Histopathological analyses were performed using oil red O, Hematoxylin and Eosin, and Masson coloration assays. Immunohistochemistry (IHC) and RT-PCR were performed to analyze protein expression and measure mRNA expression levels, respectively. RESULTS: Scoparone could ameliorate the pathological alterations observed in NAFLD-HCC mouse model. IHC analysis indicated an upregulation of NF-κB p65 expression in both NAFLD and NAFLD-HCC models, which was subsequently reverted by scoparone administration. Furthermore, scoparone treatment resulted in a reversal of the increased mRNA expression levels of NF-κB target genes, including TNF-α, MCP-1, iNOS, COX-2, NF-κB, and MMP-9, which were originally elevated in the NAFLD-HCC condition. Additionally, scoparone exhibited a capacity to counteract the activation of the MAPK/Akt signaling in the NAFLD-HCC model. CONCLUSION: These findings suggest that scoparone holds promise as a potential therapeutic agent for NAFLD-associated HCC, and its model of action may involve the regulation of inflammatory pathways governed by the MAPK/Akt/NF-κB signaling cascade.

A meta-analysis investigation to measure the relationship between vitamin D deficiency (VDD) and diabetic foot ulcer (DFU). A comprehensive literature inspection till February 2023 was applied and 1765 interrelated investigations were reviewed. The 15 chosen investigations enclosed 2648 individuals with diabetes mellitus in the chosen investigations' starting point, 1413 of them were with DFUs, and 1235 were without DFUs. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the relationship between VDD and DFU by the dichotomous and continuous approaches and a fixed or random model. Individuals with DFUs had significantly lower vitamin D levels (VDL) (MD, -7.14; 95% CI, -8.83 to -5.44, P < 0.001) compared to those without DFU individuals. Individuals with DFUs had a significantly higher number of VDD individuals (OR, 2.27; 95% CI, 1.63-3.16, P < 0.001) compared to those without DFU individuals. Individuals with DFU had significantly lower VDL and a significantly higher number of VDD individuals compared to those without DFU individuals. However, caused of the small sample sizes of several chosen investigations for this meta-analysis, care must be exercised when dealing with its values.

Objective: Liver cancer seriously threatens the health of people. Meanwhile, it has been reported that bufalin could act as an inhibitor in liver cancer. In addition, alisol B 23-acetate is a natural product derived from Alisma plantago-aquatica Linn which has an antitumor effect. In this study, we aimed to explore whether alisol B 23-acetate could increase the antitumor effect of bufalin on liver cancer. Methods: In order to detect the effect of alisol B 23-acetate in combination with bufalin on liver cancer, human liver cancer SMMC-7721 and MHCC97 cells were used as subjects. Bufalin and alisol B 23-acetate were performed on cells. Cell viability was tested by MTT assay. In addition, flow cytometry was performed to assess the cell apoptosis. Autophagy-related protein levels were tested by western blotting. Results: The data revealed that bufalin significantly decreased the viability of liver cancer cells, and the inhibitory effect was further increased by alisol B 23-acetate. In addition, alisol B 23-acetate notably enhanced the apoptotic effect of bufalin on liver cancer cells through mediation of Mcl-1, Bax, Bcl-2, and cleaved caspase-3. Meanwhile, alisol B 23-acetate in combination with bufalin induced the autophagy in liver cancer cells through mediation of Beclin-1 and p62. Furthermore, alisol B 23-acetate in combination with bufalin significantly downregulated the level of GSK-3ß and increased the expression of ß-catenin in liver cancer cells. Conclusion: In summary, these findings provide the first evidence that alisol B 23-acetate improves the anticancer activity of bufalin on liver cancer through activation of the Wnt/ß-catenin axis, and these outcomes might shed new lights on exploring the new methods against liver cancer.

OBJECTIVE: To observe the effects of navel-warming therapy on clinical efficacy in patients with yang-deficiency tympanites based on regular treatment of western medication. METHODS: One hundred and twenty cases of yang-deficiency tympanites were randomly divided into a navel-warming therapy group and a western medication group, sixty cases in each one. The regular treatment of western medicine was applied in the western medication group, including oral administration of antiviral drug and diuretics as well as intravenous drip of hepatic protector. Based on western medicine treatment, the navel-warming therapy was applied in the navel-warming group. A medical cake was laid on Shenque (CV 8), and then a medical cylinder was placed above the medical cake and ignited. The treatment was given once daily. One month was considered as a treatment session in both groups and totally one session was required. The TCM symptom score, B-ultrasound ascites and temporary use of diuretics before and after treatment were observed in both groups; also the efficacy was evaluated. RESULTS: The total effective rate was 81.7% (49/60) in the navel-warming therapy group, which was superior to 56.7% (34/60) in the western medication group (P < 0.05). After the treatment, the TCM symptom score and ascites were improved in both groups (all P < 0.05), which was more significant in the navel-warming therapy group (all P < 0.05). The temporary use of diuretics was statistically different between the two groups (P < 0.05), indicating the navel-warming therapy group could obviously reduce or stop the use of diuretics. CONCLUSION: Based on regular treatment of western medication, the navel-warming therapy could significantly improve therapeutic efficacy, effectively relieve clinical symptoms and ease ascites.

Rare earth mineral composite materials were prepared using tourmaline and cerous nitrate as raw materials. Through characterization by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, dynamic contact angle meter and tensiometer, and Fourier transform infrared spectroscopy, it was found that the composite materials had a better far infrared emitting performance than tourmaline, which depended on many factors such as material composition, microstructure, and surface free energy. Based on the results of the flue gas analyzer and the water boiling test, it was found that the rare earth mineral composite materials could accelerate the combustion of liquefied petroleum gas and diesel oil. The results showed that the addition of Ce led to the improvement of far infrared emitting performance of tourmaline due to the decrease of cell volume caused by the oxidation of more Fe2+ ions and the increase of surface free energy. The application of rare earth mineral composite materials to diesel oil led to a decrease in surface tension and flash point, and the fuel saving ratio could reach 4.5%. When applied to liquefied petroleum gas, the composite materials led to the enhanced combustion, improved fuel consumption by 6.8%, and decreased concentration of CO and O2 in exhaust gases by 59.7% and 16.2%, respectively; but the temperature inside the flue increased by 10.3%.
