The resection margin (RM) status and microscopic vascular invasion (MVI) are known prognostic factors for intrahepatic cholangiocarcinoma (ICC). An enhanced understanding of their impact on long-term prognosis is required to improve oncological outcomes.A total of 711 consecutive patients who underwent curative liver resection for hepatitis B virus-related ICC were retrospectively analyzed. The different impact of the RM status (narrow,1 cm, or wide, ≥1 cm) and MVI (positive, +, or negative, -) on overall survival (OS) and recurrence-free survival (RFS) were analyzed.The 1-, 3-, and 5-year OS rates were 67.6%, 42.5%, and 33.2% in wide RMMVI (-), 58.0%, 36.1%, and 26.5% in narrow RMMVI (-), 51.0%, 27.0%, and 24.3% in wide RMMVI (+), and 39.0%, 20.4% and 14.3% in narrow RMMVI (+) (Combined analysis of RM and MVI can better stratify the risks of postoperative death and recurrence in patients with HBV-related ICC, which may help subsequent adjuvant therapy and closer follow-up.

Background and Aim: The resection margin (RM) status and microscopic vascular invasion (MVI) are known prognostic factors for intrahepatic cholangiocarcinoma (ICC). An enhanced understanding of their impact on long-term prognosis is required to improve oncological outcomes.Methods: We reviewed data on 711 consecutive patients who underwent curative liver resection for hepatitis B virus–related ICC. The different impact of the RM status (narrow, Results: The 1-, 3-, and 5-year OS rates were 67.6%, 42.5% and 33.2% in wide RM & & MVI (-), 58.0%, 36.1% and 26.5% in narrow RM & MVI (-), 51.0%, 27.0% and 24.3% in wide RM & MVI (+), and 39.0%, 20.4% and 14.3% in narrow RM & MVI (+) (p < 0.001).The 1-, 3-, and 5-year RFS rates were 60.0%, 40.2% and 28.7% in wide RM & MVI (-), 45.2%, 34.3% and 24.2% in narrow RM & MVI (-), 40.0%, 18.5% and 12.3% in wide RM & MVI (+), and 28.2%, 11.5% and 9.8% in narrow RM & MVI (+) (p < 0.001). Multivariate analysis showed that RM & MVI were independent risk factors for the OS and RFS. Conclusions: Combined analysis of RM and MVI can better stratify the risks of postoperative death and recurrence in patients with HBV-related ICC, which may help subsequent adjuvant therapy and follow-up.

Pazopanib (trade name Votrient®) is a potent and selective multi-targeted tyrosine kinase inhibitor that blocks tumor growth and inhibits angiogenesis. Based on a recently reported procedure, we herein report the first synthesis of four potential process impurities generated in the production of pazopanib. The structure of these impurities were synthesized and characterized by 1H NMR, 13C NMR and HRMS data. The possible formation mechanisms of these impurities were also elucidated. These findings should be useful for the quality control of pazopanib in manufacture.

Data on the utilization of immunosuppressants and incidences of cardiovascular complications after kidney transplantation are generally lacking in China. The objectives of this systematic review and analysis were to investigate the hypothesis that tacrolimus and cyclosporine have different effects on the incidences of cardiovascular complications among Chinese patients after kidney transplantation. A comprehensive database research was performed in PubMed and CMB-disc. Random effect models and meta-regression were used for data analysis. Eleven eligible studies were retrieved (7 comparative studies and 4 conversion studies). There were 838 participants from the eligible studies. The incidences of drug-related hypertension, dyslipidemia and hyperglycemia were compared between tacrolimus and cyclosporine groups. Significant different odds ratios for dyslipidemia (40 vs. 20 %, OR 2.72) and hypertension (63 vs. 37 %, OR 2.93), but not for hyperglycemia (11 vs. 15 %, OR 0.705) were noted between patients receiving cyclosporine and tacrolimus containing regimens. The secondary analysis including comparative studies revealed a similar acute rejection rate, but significantly improved renal functions, lipid profiles and lower liver toxicity associated with tacrolimus. Significant reversal of hypertension and dyslipidemia was also noted in the analysis of the conversion studies. A significant association between immunosuppressant use and cardiovascular complications was identified among Chinese patients after kidney transplantation. Patients receiving cyclosporine-containing regimens and/or with chronic allograft nephropathy should be closely monitored for potential cardiovascular complications.

A facile synthetic route of linezolid 1 has been developed. Using commercially available ( R )-epichlorohydrin as the starting material, 1 was obtained through a sequence of cyclization, substitution, a Goldberg coupling, aminolysis and acetylation reactions. The synthetic route is easy to perform and can be scaled up.

The title compound (common name eplerenone), C24H30O6, is an aldosterone receptor antagonist. From the isopropyl acetate solution the compound crystallizes in monoclinic space group P 21 with a = 8.811(1) A, b = 11.250(1) A, c = 11.079(1) A, β = 93.822(12)°, Z = 2. The molecule contains three six membered rings, two five membered rings and one three membered ring. Both five membered rings display envelope conformation, whereas three six membered rings show different conformation: chair, half-chair and envelope. In the crystal the eplerenone molecules link to one another via intermolecular weak C–H···O hydrogen bonding to form the smaller cavity of 12.0(1) A3 between eplerenone molecules, no solvent molecule filled in this cavity. In the title molecule three six-membered rings show different conformation. Weak C–H···O hydrogen bonding links adjacent molecules to form the small cavity 12.0(1) A3, no solvent molecule filled in the cavity.

The eplerenone mol­ecule of the title compound, C24H30O6·C4H8O, contains three six-membered rings, two five-membered rings and one three-membered ring. In the crystal structure, the eplerenone mol­ecules are linked via C—H⋯O hydrogen bonds, forming a 303 A3 cavity, which is occupied by two disordered solvent THF mol­ecules.

Eplerenone [systematic name: 7α-(methoxycarbonyl)-3-oxo-9α,11-epoxy-17α-pregn-4-ene-21,17-carbolactone], an aldosterone receptor antagonist, crystallizes from ethanol as a monosolvate, C24H30O6·C2H6O. The eplerenone molecule has two five-membered rings, three six-membered rings and one three-membered ring. Both five-membered rings display envelope conformations, while the three six-membered rings assume envelope (cyclohexene), half-chair (cyclohexane sharing one edge with epoxy) and chair (other cyclohexane) conformations. The solvent molecule is disordered equally over two sites. It is linked to the eplerenone molecule by hydrogen bonds.
