Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Despite the therapeutic advances in HCC in the past few decades, the mortality rate of HCC is still high. Hepatitis C (HCV) infection is one of the major etiological risk factors of HCCs. However, the underlying mechanisms of HCV-induced hepatocarcinogenesis remain largely unclear. ⋯ We believe that this study can provide novel potential therapeutic and prognostic biomarkers for HCV-positive HCC.

PCSK9 inhibitors lower low-density lipoprotein (LDL) cholesterol and are efficacious at reducing vascular disease, however questions remain about potential effects on cognitive function. ⋯ We are unable to rule out meaningful associations of PCSK9 genetic variants with cognition, emphasising the potential need for continued pharmacovigilance for patients currently treated with PCSK9 inhibitors.

Atrial fibrillation (AF) is the most common heart arrhythmia. The condition is known to increase the risk of ischemic stroke (IS). Classical risk factors for the development of AF include advanced age, hypertension, diabetes mellitus, coronary heart disease and lipid metabolism disorders. Importantly, these are also recognized risk factors for ischemic stroke. Therefore, the purpose of this study was to investigate AF risk factors in patients with IS. ⋯ Our study demonstrates a need for thorough and systematic monitoring of post-ischemic stroke patients in whom AF has not been detected and who display other important risk factors. Regardless of the stroke, these factors may be responsible for development of AF.

The incidence of hyperuricemia (HUA) at younger ages is increasing along the coastal regions of China. This study aimed to compare the frequency of dual energy CT (DECT) urate crystal deposition between symptomatic hyperuricemic children and asymptomatic hyperuricemic children. ⋯ Urate deposition can occur in children with HUA, and these deposits occur more frequently in hyperuricemic children with a history of arthritis symptoms. Also, the urate deposition in the first MTP joint and calcaneus was more prevalent than in other joints. It is important to give more attention to hyperuricemic children.

Progressive accumulation of amyloid-β (Aβ) is a pathological trait of Alzheimer's disease (AD). Amyloid-β increases free radical production in neuronal cells, leading to neuronal cell death. Hormone replacement therapy can reduce the incidence of AD, and oestrogen significantly improves the clinical signs in patients with AD. However, the long-term use of oestrogen causes a variety of diseases. Phytoestrogens have been reported to bind and activate oestrogen receptors in mammals and humans to produce oestrogen-like or anti-oestrogen-like effects. Kaempferol is a flavonoid phytoestrogen that can produce a certain protective effect in neurons. However, the molecular mechanism of kaempferol in AD is unclear. ⋯ Kaempferol protected PC-12 cells against Aβ25-35-induced cell apoptosis through the ER/ERK/MAPK signalling pathway.
