ABSTRACT
Objective To investigate the effect of Zhubei Dingchuan pill on clinical symptoms and inflammatory mediators in serum and induced sputum of patients with chronic bronchitis. Methods 80 cases of patients with chronic bronchitis treated in the Department of Respiration in our hospital from January 2016 to January 2017 were selected and were randomly divided into the control group and the observation group, with 40 cases in each group. The control group was given symptomatic support treatment and the observation group was additionally given Zhubei Dingchuan pills on the basis of the control group. The changes of inflammatory mediators levels in serum and induced sputum were measured before and after treatment between the two groups, and the clinical efficacy was observed in the two groups. Results After treatment, the levels of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and high-sensitivity C reactive protein (hs-CRP) in serum or induced sputum in the observation group were significantly lower than those in the control group (P<0.05). The effective rate of treatment in the observation group was significantly higher than that in the control group (95.0％ vs. 82.5％) (P<0.05). Conclusion Zhubei Dingchuan pill can effectively relieve the clinical symptoms in patients with chronic bronchitis, and its pharmacological mechanism is related to the decrease of levels serum and airway inflammatory mediators.
ABSTRACT
A UPLC-MS/MS method based on metabonomic skills was developed to study the serum metabolic changes of rats after acute liver injury induced by CCl4 and to evaluate the action mechanism of Si-Ni-San. The integrated data were exported for principal components analysis (PCA) by using SIMCA-P software, in order to find the potential biomarkers. It showed that clear separation of healthy control group, model group, silymarin group, Si-Ni-San group was achieved by using the PCA method. Nine significantly changed metabolites were identified as potential biomarkers of acute liver injury. Compared with the health control group, the model group rats showed higher levels of phenylalanine, tryptophan and GCDCA together with lower levels of LPC 16 : 0, LPC 18 : 0, LPC 18 : 1, LPC 16 : 1, LPC 20 : 4 and LPC 22 : 6. These changes of serum metabolites suggested that the disorders of amino acid metabolism, lipid metabolism, bile acid biosynthesis and anti-oxidative damage were related to acute liver injury induced by CCl4. Si-Ni-San might have the anti-liver injury effect on all these four metabolic pathways.
ABSTRACT
This study was aimed to establish an HPLC method to simultaneous determine 6 kinds of monoester and diester aconitum alkaloids. The content of alkaloids in aconite roots, black and white prepared lateral root of aconite and the compatibility of aconite roots with rhubarb were determined. This study provided reference for the interpreta-tion of the attenuation of processing and compatibility of medicines from chemical component aspect. The HPLC analysis was performed on a Phenomenex Gemini C18 (4.6 mm í 250 mm, 5 μm) with 40 mmol·L-1 ammonium ac-etate (adjusted to pH 9.8 with ammonia water) and acetonitrile as mobile phase, with a gradient elution at the flow rate of 1.0 mL·min-1 and a detection wavelength of 235 nm. The results showed that 6 alkaloids in aconite roots achieved favorable separation and a good linearity relationship (r > 0.999) over the studied concentration range. The extraction recoveries were ranged from 96.9% to 102.4% for the 6 alkaloids. The content of diester alkaloids de-creased markedly in processed products and the compatibility of aconite roots with rhubarb compared with the raw a-conite roots. It was concluded that this method was stable, reliable, simple and practical. It can be used for the si-multaneous determination of 6 kinds of monoester and diester aconitum alkaloids in aconite roots. This processing and compatibility can significantly reduce the content of alkaloids in aconite roots in order to reduce its toxicity.
