Clinical outcomes of hepatic arterial infusion chemotherapy combined with tyrosine kinase inhibitors and anti-PD-1 immunotherapy for unresectable intrahepatic cholangiocarcinoma.

Objective: To compare the treatment efficacy and safety of tyrosine kinase inhibitors (TKIs) and anti-programmed cell death 1 (PD-1) immunotherapy combined with transarterial chemoembolization (TACE) or hepatic arterial infusion chemotherapy (HAIC) for patients with unresectable intrahepatic cholangiocarcinoma (ICC).

Methods: Patients with unresectable ICC received TKIs and anti-PD-1 immunotherapy combined with HAIC (HTP group) or TACE (TTP group) were included. The clinicopathological characteristics, treatment efficacy, and adverse events (AEs) were compared between the two groups.

A general strategy to prepare different types of polysaccharide-graft-poly(aspartic acid) as degradable gene carriers.

Owing to their unique properties such as low cytotoxicity and excellent biocompatibility, poly(aspartic acid) (PAsp) and polysaccharides are good candidates for the development of new biomaterials. In order to construct better gene delivery systems by combining polysaccharides with PAsp, in this work, a general strategy is described for preparing series of polysaccharide-graft-PAsp (including cyclodextrin (CD), dextran (Dex) and chitosan (CS)) gene vectors. Such different polysaccharide-based vectors are compared systematically through a series of experiments including degradability, pDNA condensation capability, cytotoxicity and gene transfection ability.

Acetonitrile-triaqua-[3-eth-oxy-1,8-(3,6,9-trioxaundecane-1,11-diyldi-oxy)-9H-xanthen-9-one]terbium(III) tris-(perchlorate).

In the title compound, [Tb(CH(3)CN)(C(23)H(26)O(8))(H(2)O)(3)](ClO(4))(3), the Tb(3+) atom is eight-coordinated by one N atom of an acetonitrile molecule, three water O atoms and four ligand O atoms. The Tb(3+) atom is located on one side of the macrocycle and the carbonyl oxygen coordinated to the terbium [Tb1-O1= 2.210 (3) Å] is bent out of the xanthone plane by 0.
