A variety of novel indole-derived γ-hydroxy propiolate esters were designed, synthesized, and evaluated for their anti-inflammatory activity in-vitro and in-vivo. According to the nitric oxide (NO) inhibitory analysis, all compounds showed potent NO inhibitory ability in a dose-dependent manner, with no apparent cytotoxicity. The model compound, L-37, also exhibited significant potency in PGE inhibition. In addition, compounds L-37 and L-39 can downregulate the expression of COX-2 enzyme at 5 μM via ELISA experiment. Compound L-37 (1 μM) also inhibited the PGF production as well as the expression of COX-1, but displayed weak inhibition activity towards the Leukotrienes (LT) and Thromboxane-B2 (TXB-2) production. However, the expression of 5-LOX was significantly inhibited by compound L-39 at 5 μM. Xylene-induced ear edema model was explored for in-vivo anti-inflammatory evaluation, compound L-37 showed similar inhibitory activity compared with celecoxib, approximately 80% at 50 mg/kg dosage. Every outcome showed that the newly synthesized compounds can effectively inhibit inflammation.

Aims: Bisphenol A (BPA), xenoestrogen, is an environmental toxicant, that generates oxidative stress leading to cardiotoxicity. The oxidative stress can be neutralized by natural and synthetic antioxidants. The present study elucidates the highly selective antioxidative potential of synthetic tetra aniline polymers Es-37 and L-37 against Bisphenol A-induced cardiac cellular impairments and the role of miRNA-15a-5p in the regulation of different apoptotic proteins.

Objective: To explore the clinical effect of Li-Dan-He-Ji in the treatment of infantile cholestatic hepatic fibrosis.
Methods: Patients who met the diagnostic criteria of infantile cholestatic hepatic fibrosis in the department of integrated traditional Chinese and Western medicine and the department of gastroenterology of Wuhan Children's Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from January to December 2021 were included in the study by prospective randomized controlled trial. They were divided into the conventional treatment group and Li-Dan-He-Ji group according to the random number table.

Abnormal bone metabolism and subsequence osteoporotic fractures are common complications of chronic inflammatory diseases. No effective treatment for these bone-related complications is available at present. The chronic inflammatory state in these diseases has been considered as a key factor of bone loss.

In this work, nickel ferrite nanoparticles (NiFeO NPs) was prepared to improve hydrogen (H) production by dark fermentation. Moderate amounts (50-200 mg/L) promoted H generation, while excess NiFeO NPs (over 400 mg/L) lowered H productivity. The highest H yields of 222 and 130 mL/g glucose were obtained in the 100 mg/L (37 °C) and 200 mg/L NiFeO NPs (55 °C) groups, respectively, and the values were 38.
