RESUMO
Objective:To evaluate the compatibility laws of effective-component compatibility of Bufei Yishen formula Ⅲ (ECC-BYFⅢ) in regulating mucus hypersecretion of chronic obstructive pulmonary disease (COPD).Methods:According to the efficacy of the original Chinese medicine, the components of ECC-BYFⅢ were divided into four categories: Buqi (Ginsenoside Rh1+Astragaloside), Bushen (Icariin), Huatan (Nobiletin), and Huoxue (Paeonol). The four categories were divided into 14 groups based on the method of mathematical permutation. ① The rats were divided into control group, model group, ECC-BYFⅢ, and different components compatibility groups according to the random number table, totaling 17 groups. COPD rat model in stable phase was established by cigarette smoke exposure combined with repeated bacterial infections. The corresponding drugs were given by gavage at the 9th week of modeling, and the samples were collected at the end of the 16th week. The levels of matrix metalloproteinase-9 (MMP-9) and tissue inhibitors of metalloproteinase 1 (TIMP-1) in serum and bronchoalveolar lavage fluid (BALF), and the levels of mucin (MUC) 5AC in lung tissue and BALF were detected by enzyme linked immunosorbent assay (ELISA). ② Human lung epithelial cells BEAS-2B were divided into blank group, model group, and different components compatibility groups. Hypoxia-induced mucus hypersecretion model of human lung epithelial cells BEAS-2B was established 4 hours after corresponding drug pretreatment. The mRNA expressions of MUC5AC, MUC5B, and MUC1 were detected by quantitative polymerase chain reaction (PCR). The mucus secretion indexes of rats and BEAS-2B cells were evaluated by Region (R) value comprehensive evaluation method.Results:① Compared with the control group, MMP-9 in serum and BALF from the model group were significantly increased, the level of TIMP-1 was significantly decreased, and MUC5AC in lung tissue and BALF were significantly increased. The results of R value comprehensive evaluation showed that except for the Buqi and Bushen groups, ECC-BYFⅢ and other components compatibility groups significantly corrected mucus hypersecretion in COPD rats, ECC-BYFⅢ, Bushen Quxie, Fuzheng Huatan, and Quxie groups were much better (R values were 2.15±0.42, 2.11±0.23, 2.16±0.23 and 2.16±0.55, respectively), compared with the model group (R value: 3.00±0.00), the differences were statistically significant (all P < 0.05). ② Compared with the blank group, the mRNA expressions of MUC5AC, MUC5B, and MUC1 increased in the model group. But different components compatibility groups had no significant effects on the mucus secretion of BEAS-2B cells. ③ The comprehensive evaluation results of R value about each in vivo and in vitro index showed that ECC-BYFⅢ, Huoxue, Quxie, Bushen Huoxue, Fuzheng Huatan, Buqi Quxie groups significantly corrected the mucus hypersecretion (R values were 2.30±0.43, 2.33±0.44, 2.12±0.68, 2.27±0.64, 2.24±0.27 and 2.29±0.47, respectively), compared with the model group (R value: 3.00±0.00), the difference was statistically significant (all P < 0.01). The order was: Quxie > Fuzheng Huatan > Bushen Huoxue > Buqi Quxie > ECC-BYFⅢ > Huoxue. Conclusions:Different components compatibility of ECC-BYFⅢ had different effects on COPD mucus secretion. The components containing Huatan (Nobiletin) or Huoxue (Paeonol) showed a better inhibitory effect on mucus secretion.
RESUMO
This experimental study was aimed to find the effect of different package and storage conditions on the content of effective components of A stragalus pieces. A stragalus pieces were stored under different storage conditions by using different packaging materials and packaging methods. Every three months, the contents of Calycosin-7-glu-coside and astragaloside were determined according to the 2010 version of Chinese Pharmacopoeia. With the extend-edstorage time, the contents of two effective components were significantly decreased. After six-monthstorage, the contents were not consistent with the standard of the pharmacopoeia standards. Room temperature had relatively big influence on the loss of content. The plastic and aluminum paperpackagingwere better than kraft paper packaging. The content ofastragaloside using non vacuum packaging method was relatively higher than the vacuum packaging. Contentunder the conditions of cool storehouse and nonvacuum plastic bags was higher than other packagingmethod. And the changes of both contents were relatively stable. It was concluded that the A stragaluspieces should be packed with non vacuum plastic bags, and stored in a cool and dry place.
