RÉSUMÉ

Acupuncture regulating gastrointestinal motility has the characteristics of bidirectional benign regulation, acupoint specificity and immediacy. And its regulation is mainly achieved through the "neuro-endocrine-immune" network system. Acupuncture at Neiguan (PC 6) and Hegu (LI 4) to inhibit intestinal peristalsis may have good application value in colonoscopy.

RÉSUMÉ

Aim To investigate the pharmacokinetic properties and in vitro enzyme activities of D-a-to- copherol polyethylene glycol 1000 succinate-modified arginine deiminase cyclodextrin lipid nanoparticles (ACLN). Methods The diacetylmonooxime-thiosem- icarbazide colorimetric method was used to determine the ADI enzyme activity, and the double reciprocal plot method was used to determine the enzyme Michae- lis constants. After the rats were given intravenously free ADI and ACLN, rat plasma samples were taken at different time points to determine the activity of ADI, and the time-enzyme activity curve would be drawn and the pharmacokinetic data analyzed by DAS 2. 1. 1. Re¬sults The optimum temperature for ADI and ACLN was 37 °C and the optimum pH was 6. 5. The Km val¬ ues of free ADI and ACLN were 0. 87 and 0. 74 mmol • L"1, respectively. The Vmai values of free ADI and ACLN were 53.28, 62.50 fjimol • L"' • min"1, re-spectively. The V

RÉSUMÉ

2-[3-hydroxy-1-adamantyl]-2-oxoacetic acid [IV], a key intermediate of saxagliptin for type 2 diabetes mellitus [T2DM], was prepared from 1-adamantanecarboxylic acid[I] via oxidation by potassium permanganate[KMnO4] to afford 3-hydroxy-1-adamantanecarboxylic acid [II], which was treated with a one-pot method to give 1-acetyl-3-hydroxyadamantane [III] followed by oxidation. Some key steps were optimized and the overall yield was about 51%
