Activation of CYP3A by Accelerated Blood Clearance Phenomenon Potentiates the Hepatocellular Carcinoma-Targeting Therapeutic Effects of PEGylated Anticancer Prodrug Liposomes.

Reduced enzyme activity in hepatocellular carcinoma (HCC) and poor targeting limit the application of enzyme-activating prodrugs, which is also detrimental to the effective treatment of HCC. Here, we investigated whether accelerated blood clearance (ABC) phenomenon occurs in HCC models following repeated injections of PEGylated liposomes (PEG-L), thus inducing prodrug accumulation and activation in the liver and exerting highly effective and low-toxicity therapeutic effects on HCC. First, PEGylated liposomal cyclophosphamide was prepared by solvent injection and characterized.

Absence of fluctuation and inverted circadian rhythm of blood pressure increase the risk of cognitive dysfunction in cerebral small vessel disease patients.

Background And Purpose: Cerebral small vessel disease (CSVD) is a common cause of stroke and senile vascular cognitive impairment, imposing a heavy burden on public health care systems worldwide. Hypertension and 24-hour blood pressure variability (BPV), known to be significant risk factors for cognitive dysfunction, have been found to be associated with cognitive function in CSVD patients in previous studies. However, as a derived part of BPV, there are few studies on the relationship between circadian rhythm of blood pressure and cognitive dysfunction in CSVD patients, and the relationship between them is still unclear.
