Hepatic sclerosing hemangioma (HSH) is a rare benign tumor that is considered fibrosis and hyaline change caused by degenerative changes of cavernous angioma, and changes in pathological features cause the changes in imaging features, making this atypical hemangioma easily misdiagnosed as primary or metastatic malignant tumor. Although there are many studies on the imaging findings of this disease, it is still difficult to diagnose and most patients underwent resection since it is misdiagnosed as malignant tumor. There is still a low rate of confirmed diagnosis before surgery. This article elaborates on the etiology, clinical manifestations and pathological features, imaging findings, diagnosis, and treatment of HSH, in order to provide a reference for the diagnosis and treatment of this disease.

Objective: The current investigation aimed to determine the appropriate dosage form by comparing solid dispersion and liposome to achieve the purpose of improving the solubility and bioavailability of linarin. Methods: Linarin solid dispersion (LSD) and linarin liposome (LL) were developed via the solvent method and the thin film hydration method respectively. The Transwell chamber model of Caco-2 cells was established to evaluate the absorption of drug. The pharmacokinetics of linarin, LSD and LL in rats after ig administration were carried out by high performance liquid chromatography (HPLC) method. Results: The solubility of LSD and LL was severally 3.29 times and 3.09 times than that of linarin. The permeation coefficients of LSD and LL were greater than 10
