We sought to analyze the preferred treatment modality by age and liver function in South Korea.
The Korean Liver Cancer Study Group randomly extracted the data of patients with hepatocellular carcinoma (HCC) enrolled in the Korean Central Cancer Registry from 2008 to 2014 from approximately 50 hospitals nationwide. After excluding distant and lymphatic metastases, the treatment preference for patients with a single lesion (excluding PVT (portal vein thrombosis), hepatic vessels, and bile duct invasion) and with PVT was evaluated in 7559 patients. Patients were grouped by age, and baseline liver function was divided based on the Child-Pugh class (CPC)
,
, and
.
For a single HCC, the majority of patients selected transarterial therapy as the initial treatment, followed by surgical resection and local ablative therapy. The surgical resection rate decreased significantly with age (
< 0.001), and the transarterial therapy rate significantly increased (
< 0.001). For CPC C, liver transplantation was significantly increased to 11.5%, and 36.3% of patients received no treatment. In HCC with PVT, the transarterial therapy rate was the highest, followed by the rate of abandonment of treatment. The proportion of no treatment significantly increased with age (
< 0.001). In CPC C, transarterial therapy and systemic therapy were attempted in 15.4% and 5.8% of patients, respectively.
Age and liver function have a significant impact on the therapeutic decision-making of HCC patients in Korea. In unfavorable conditions, surgical resection was less favored in patients with single tumors, and no treatment was preferred in patients with PVT.

The inclusion complexes of flavonoids with HP-β-CD was prepared by the freeze-drying method and its characterization was investigated by different analytical techniques including ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry, and X-ray diffractometry. The catechin/HP-β-CD complex exhibited the highest encapsulation efficiency (83.37%), followed by epicatechin/HP-β-CD (81.51%), morin hydrate/HP-β-CD (81.38%), and quercetin/HP-β-CD (81.16%). The inclusion complexes of HP-β-CD showed a decrease in the absorption of flavonoids with a small shift (≈2 nm) of the λmax, while similar to the characteristic absorption peak of flavonoids. However, the FT-IR spectra of the flavonoid/HP-β-CD inclusion complexes did not display any features that were like the pure flavonoids, although the spectra were very similar to that of HP-β-CD. The melting point of flavonoids disappeared, and the thermal properties of HP-β-CD were altered following formation of the inclusion complex between flavonoids and HP-β-CD, resulting in a shift in the melting peak.The objective of this study was to synthesize and characterize inclusion complexes of phenolic acids with hydroxypropyl-β-cyclodextrin (HP-β-CD). The inclusion complexes were prepared by the freeze-drying method and characterized using a variety of analytical techniques, including ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, and X-ray diffractometry. The results of all these approaches indicated that phenolic acids were able to form an inclusion complex with HP-β-CD, and the phenolic acids/HP-β-CD inclusion compounds exhibited different spectroscopic features and properties based on the phenolic acids employed. The use of the HP-β-CD matrix allowed for higher encapsulation efficiency and afforded capsules with distinct shapes.The present study was aimed to evaluate the phytochemical contents and hepatocyte protective effects of functional extracts from rice bran of indica and japonica rice cultivars, Dasan 1 and Ilpum, respectively. Tipiracil clinical trial The highest vitamin E (23.51 mg/g) and phytosterol (390.25 mg/g) content was observed in the unsaponifiable matter (USM) of Dasan 1 cultivar. However, USM of Ilpum showed the highest content of total policosanol and squalene (232.73 mg/g and 99.31 mg/g, respectively). The methanolic extract from the defatted rice bran (MEDR) of Dasan 1 showed the highest total polyphenol content, reducing power, and radical scavenging capacity, while USM of Dasan 1 showed the highest cell viability (81.3%) against oxidative stress in HepG2 cells. USM significantly increased glutathione levels and suppressed the production of reactive oxygen species in hepatocytes compared with methanolic extracts of the rice bran oils and/or MEDR. These results provide useful information on the functional extracts of rice bran from indica and japonica rice cultivars, including their antioxidant properties and cytoprotection in HepG2 cells.This study proposes the processing method that could maximize the functional properties of evening primrose seeds (EPS) and its various nutritional components. EPS can be prepared by different methods, such as being left raw, roasting, steaming, and powdering. Processing of EPS to create EPS powder (EPSP) resulted in higher levels of vitamin E, fatty acids, total phenolic contents, and antioxidant activity, compared with the other processing methods. Also, EPSP maintained lipid peroxidation inhibitory activity for 49 days. In particular, the EPSP ethyl acetate (EtOAc) fraction exhibited high antioxidant, antidiabetic, and angiotensin I-converting enzyme inhibitory activities. The EPSP ethyl acetate fraction showed a high cytoprotective effect against H2O2-induced cell damage in both RAW264.7 and EA.hy926 cells. In addition, the EtOAc fraction showed anti-inflammatory activity by the inhibitory activity of nitric oxide (NO) in RAW264.7 cells, and antihypertensive activity by the activity of NO in EA.hy926 cells.
