RESUMEN
OBJECTIVE： To mine and analyze the formulation rules of Chinese patent medicine for cold， and to provide reference for clinical dialectical medication and R&D of new medicine for cold. METHODS： The name， dosage form， formulation， function of curing of Chinese patent medicines for cold were collected from 2015 edition of Chinese Pharmacopeia （part Ⅰ） and then input into TCM Inheritance Assistant Platform V 2.5； use frequency of TCM were counted. Apriori algorithm and association rules were used to analyze the core medicinal material combination （10％ support and 0.65 confidence）. New formulation combinations were extracted by unsupervised entropy hierarchical clustering method. RESULTS： A total of 130 kinds of Chinese patent medicine （196 Chinese patent medicine with the same prescription and different dosage forms） for treating cold were collected， including granules （47）， pills （32）， tablets （31）， mixtures （31）， etc. 264 medicinal materials were involved. The cold syndromes contained wind-heat syndrome， wind-cold syndrome， summer-dampness syndrome and Qi deficiency syndrome. Top 3 medicinal materials in the list of use frequency were Glycyrrhiza uralensis （45.38％）， Scutellaria baicalensis （32.31％） and Platycodon grandiflorus （31.54％）. There were 28 core medicinal material combinations， among which the top 3 were G. uralensis-P. grandiflorus， Mentha haplocalyx-P. grandiflorus and S. baicalensis-Forsythia suspensa. New combinations were excavated， including Nepeta cataria-P. grandiflorus-M. haplocalyx-Citrus reticulate-Folium Perillae-Citrus aurantium- Poria cocos， F. suspense-S. baicalensis-Lonicera japonica- Arctium lappa-Fermented soybean. CONCLUSIONS： This study analyzed the formulation rules of Chinese patent medicine for treating cold by using the TCM inheritance assistant platform V2.5， which can provide reference for clinical dialectical medication and R&D of new medicines for cold.
RESUMEN
Objective To investigate Yiqi Huatan Decoction(YHD), a compound recipe with the actions of tonifying Qi and resolving phlegm, on aquaporin 5(AQP5), tumor necrosis factor-alpha(TNF-α)and mucin 5AC(MUC5AC)in bronchoalveolar lavage fluid(BALF)of chronic obstructive pulmonary diseases(COPD)rats. Methods SD rats were randomized into blank control group, model group, and low-, middle- and high-dose YHD groups(in the dosage of 7.398, 36.99, 73.98 g·kg-1·d-1 respectively). The rat model of COPD was induced by cigarette smoking combined with intratracheal dripping of lipopolysaccharide(LPS). After COPD rats were treated with YHD for 30 days, the histological features of lung tissues were observed after hematoxylin-eosin (HE) staining, the expression of AQP5, TNF -α and MUC5AC in the lung tissue was detected by immunohistochemistry, the concentrations of AQP5, TNF-α and MUC5AC in BALF of rats were measured by enzyme-linked immunosorbent assay(ELISA). Results Compared with the blank control group, the concentration of AQP5 in BALF of the model group was decreased significantly(P<0.01), while the concentrations of TNF-αand MUC5AC were significantly increased(P<0.01). Compared with the model group, the pathological features of the lung tissue were relieved, and the concentration of AQP5 was increased significantly in low-, middle-, high-dose YHD groups (P<0.01), but the concentrations of TNF-α and MUC5AC were significantly decreased (P<0.01), and the effect of high-dose group was superior to low-and middle-dose groups(P<0.01). Conclusion The therapeutic mechanism of YHD for COPD is probably related with the regulation of fluid transport in aquaporin water channels of rats.

Objective To investigate the therapeutic effect of acupoint selection by heavenly stems on eosinophils(EOS) in guinea pigs with asthma.Methods Forty-eight guinea pigs were randomized into four groups: group A(timely electroacupuncture at the period of the day from 3 p.m.to 5 p.m.),group B(un-timely electroacupuncture at the period of the day from 9 a.m.to 11 a.m.),group C(model group) and group D(normal control group).Asthma was induced by chicken ovalbumin in groups A,B and C.The hematoxylin-eosin(HE) staining method and terminal-deoxynucleotidyl transferase-mediated nick end labeling(TUNEL) method were applied in the pathological and quantitative observation of eosinophils(EOS) in lung slices.Results The number of EOS was increased in model group(P
