Drying is the most common and fundamental procedure in the post-harvest processing which contributes to the quality and valuation of medicinal plants. However, attention to and research work on this aspect is relatively poor. In this paper, we reveal dynamic variations of concentrations of five major bioactive components, namely salvianolic acid B (SaB),(More)
Danshen, the dried roots of Salvia miltiorrhiza, is an extremely valued Traditional Chinese Medicine. Previously, we have demonstrated that salvianolic acid B (SaB), the important bioactive ingredient in this herb, was a post-harvest product. Here, we further reported that all salvianolic acids (SAs) in the roots were post-harvest products of the drying(More)
BACKGROUND The RP-HPLC resolution of two triterpenic acid isomers was unstable. OBJECTIVE To separate the oleanolic acid (OA) and ursolic acid (UA) simply within RP-HPLC. MATERIALS AND METHODS The separation ability of five stationary phases was studied with the retention effect of their carbon loads. Also the resolution effects of mobile phase(More)
OBJECTIVE To explore the characteristics and application of mismatch negativity in hyperbilirubinemia neonates. METHOD Eighty-six neonates with hyperbilirubinemia divided into low and high groups according to the bilirubin concentration of 342 micromol/L and 15 normal neonates for control group were measured with MMN and ABR. All subjects were enrolled(More)
In this study, twenty disazo reactive red dyes with J acid as coupling components were selected, and their ground state geometry were studied with BLYP functional and TZVP basis set. The UV-vis absorption spectra were calculated by time-dependent density functional theory (TDDFT) employing B3LYP and PBE0 hybrid functionals and TZVP basis set, and the(More)
We report here a case of nasal natural killer/T-cell lymphoma with metastasization into the pancreas. A 43-year-old Chinese female patient presented with right nasal obstruction and purulent rhinorrhea that lasted for the past half year and worsened gradually despite antibiotic medical treatment. Physical examination revealed a mass in the right nasal(More)
BACKGROUND Inflammation plays a critical role in the progression of atherosclerosis, and hyperglycemia is a common feature in patients with ACS. We investigated the relationship between fasting plasma glucose (FPG) levels and the levels of the inflammatory factor, myeloperoxidase (MPO), in patients with acute coronary syndrome (ACS). METHOD A total of 85(More)
BACKGROUND Anabolic steroids are known to improve body composition and muscle strength in healthy people. However, whether anabolic steroids improve the physical condition and function in patients with chronic obstructive pulmonary disease (COPD) remains undetermined. A meta-analysis was conducted to review the current evidence regarding the effects of(More)
