In this study, the strong-acid polystyrene resin D001 was modified by impregnation with metal ions Fe 31 , Cu 21 , and Zn 21 to prepare new kinds of sorbents. The modified D001 was characterized by N 2 sorption-desorption isotherms, X-ray powder diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR). The sorption performance of the metal modified resins for removal of antibiotics tetracycline (TC) and doxycycline (DC) from aquatic environment was investigated and excellent sorption capability with more than 98% removal ratio was observed for these resins after modification. Although these modified resins also presented pH-dependent sorption, they showed much better flexibility with pH fluctuation than those of the unmodified original D001, and extremely strong sorption capability was exhibited in a wide range of pH 2-8 for both TC and DC. Pseudo-second-order kinetic equation described the sorption process more reasonably than pseudo-first-order equation. Langmuir isotherm model provided the best match to the equilibrium data with monolayer maximum sorption capacity of 417-625 mg g 21 under 288-318 K. The sorption capacity decreased with the increase of ionic strength of NaCl. The main sorption mechanism was proposed to be surface complexation, cation bridge interaction and electrostatic attraction/competition between antibiotics and metal modified resins.

Aim of the Study. This study is aimed at exploring the effects and pharmacological mechanisms of the extracts from the Heritiera littoralis fruit (EFH) on dextran sulfate sodium- (DSS-) induced ulcerative colitis (UC) in mice. Materials and Methods. The chemical compositions of EFH were identified using LC-ESI-MS. The mice with 3% DSS-induced UC were administered EFH (200, 400, and 800 mg/kg), sulfasalazine (SASP, 200 mg/kg), and azathioprine (AZA, 13 mg/kg) for 10 days via daily gavage. The colonic inflammation was evaluated by the disease activity index (DAI), colonic length, histological scores, and levels of inflammatory mediators. The gut microbiota was characterized by 16S rRNA gene sequencing and analysis. Results. LC-ESI-MS analysis showed that EFH was rich in alkaloids and flavones. The results indicated that EFH significantly improved the DAI score, relieved colon shortening, and repaired pathological colonic variations in colitis. In addition, proteins in the NF-κB pathway were significantly inhibited by EFH. Furthermore, EFH recovered the diversity and balance of the gut microbiota. Conclusions. EFH has protective effects against DSS-induced colitis by keeping the balance of the gut microbiota and suppressing the NF-κB pathway.
