ABSTRACT
OBJECTIVE：To provide reference for improving TCM treatment of pulmonary nodule. METHODS ：The experience of famous TCM doctors in the TCM treatment of pulmonary nodule was searched by computer ，the formulations of the cases were sorted out ，and the data were recorded into the TCMISS V 2.5 for data analysis ，and the medicine frequency was counted. Apriori algorithm and association rules were used for statistical analysis of core combination of formulations （support degree was 16，confidence degree was 0.65）. Inner core combination and new combination were extracted according to the entropy clustering method of complex system （correlation was 6，penalty was 2）. RESULTS ：A total of 25 literatures were input ，including 64 formulations in total ，166 medicinal materials. For the prescriptions of pulmonary nodule ，the frequency of single ingredient from high to low was Bolbostemma paniculatum ，Glycyrrhiza uralensis ，Astragalus membranaceus ，Prunella vulgaris ，Ostrea gigas，Angelica sinensis ，Pinellia ternate ，Ligusticum chuanxiong ，Mori Corlex ，etc. The main compatibility of the drug model is to invigorate Qi ，dissipate phlegm ，invigorate Qi and activate blood circulation ，and promote Qi and softness ，such as “G. uralensis，B. paniculatum ”“A. membranaceus ，B. paniculatum ”“A. membranaceus ，G. uralensis ”，etc；10 core combinations of the drug were found out ， such as Begonia fimbristipula-Rhodiola rosea-Bupleurum Chinense ， Cervus elaphus Clematis chinensis-Buffalo Horn，etc. There were 5 new prescriptions ，i.e. B. fimbristipula-R. rosea-B. chinense-Setaria italic ，C. elaphus-C. chinensis-Buffalo Horn-French chalk ，A. sinensis-L. chuanxiong-Morus alba- Mori Corlex -P. vulgaris-Ganoderma lucidum ，Hedyotis diffusa-Prunus persica-Trichosanthes kirilowii-Achyranthes bidentata-Eupolyphaga sinensis- Cinnamomi Ramulus ，A. bidentata-E. sinensis-Ephedra sinica-Curcuma aromatica-Curcuma longa-Concretio silicea . CONCLUSIONS ：Most modern doctors believe that the interaction of phlegm and blood stasis is the main pathogenesis of pulmonary nodule ，and the treatment is mainly based on the treatment of lung ，spleen，liver and kidney ，focus on the elimination of symptoms and phlegm ，the elimination of blood stasis and the soft and hard treatment ，pay attention to the weak body of the patient. TCM treatment of pulmonary nodule has a good prospect.
ABSTRACT
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.
ABSTRACT
Objective To observe the effect of Jianpi Buxue Decoction on the protein expression of neurokinin 1 receptor (NK1R) and CD34 in C57BL/6 mice of lung cancer after chemotherapy, and to explore the improvement of chemotherapy-induced nausea and vomiting and myelosuppression treated with Jianpi Buxue Decoction. Methods Forty C57BL/6 mice were transplanted with Lewis lung cancer cells in the armpit of left anterior limb after being fed for 7 days, and then were randomly divided into lung cancer group, model group, and high-, middle- and low-dose Chinese medicine groups. Model group and Chinese medicine groups were injected intraperitoneally with cyclophosphamide (80 mg/kg) for one day. Lung cancer group and model group were given normal saline. Chinese medicine groups were administered with high-, middle- and low-dose of Jianpi Buxue Decoction (25, 12.6, 6.25 g/kg respectively) for 14 days. After the modeling, all of the mice were sacrificed, and then the brains and spleens were sampled. Western blotting method was used to detect the protein expression of NK1R and CD34. Results Compared with lung cancer group, the protein expression of cerebral NK1R and splenic CD34 in the model group was increased significantly ( P<0.01) . Compared with the model group, the protein expression of NK1R in mice brain tissues of high-, middle- and low- dose Jianpi Buxue Decoction groups was decreased significantly (P<0.01) , while the protein expression of CD34 in spleen tissues of middle-and low-dose Jiangpi Buxue Decoction groups was increased obviously ( P<0.05) . Conclusion Jianpi Buxue Decoction has an effect on down-regulating the protein expression of NK1R in brain tissues and on up-regulating the protein expression of CD34 in spleen tissues of C57BL/6 mice with lung cancer after chemotherapy, indicating that Jianpi Buxue Decoction probably can relieve chemotherapy-induced nausea and vomiting, and can improve the myelosuppression after chemotherapy.
ABSTRACT
Clinical teaching is an important part of teaching which has a bearing on the level of medical teaching and the quality of personnel training. The clinical teaching ability of young physicians is related to the whole teaching process. So Young physicians should be a serious clinical teacher with good medical ethics, strict clinical thinking, formal clinical skills.
