[Abstract]:Background Chinese medicine has some advantages in the treatment of pneumonia and asthma in children. Wang Chuan professor has a significant effect, high safety and less side effects in the treatment of pneumonia and asthma. Therefore, it is necessary to excavate Professor Wang in the treatment of pneumonia and asthma. Methods based on 249 cases of pneumonia and asthma in Professor Wang's outpatient clinic, by using SPSS 19 and Clementine 12 software to cluster and analyze the association rules of 29 kinds of high frequency drugs, the results of the 1. cluster analysis were divided into 4 categories:.C1:, bitter almond, Scutellaria, Polygonum cuspidatum, drapine seed, soda and front. Hu; C2: mulberry leaf, mulberry, loquat leaf, loquat leaf, Magnolia and heavy building; C3: Platycodon, Fructus aurantii, Fritillaria, Trichosanthes, Trichosanthes, garden, hundred, raw gypsum and Salvia; C4:, Radix Astragali, Rhizoma Atractylodes, Alba, calcined oysters,.2. association rules analysis: from the two drug association, the forelaus and ephedra, sago ephedra and almonds, mulberry leaves and mulberry and mulberry bark, the forelahu and Almond, soda and Sophie, Soviet and forelahu, Radix Scutellariae, Scutellaria, Scutellaria, Scutellaria, Scutellaria, cen, Dan Nan star and Cen, Dan Nan star and forelahu, mulberry and scutellaria, and other two common drug combinations; from the correlation of three drugs, the basic manifestation of the treatment of pneumonia and asthma is to declare the lung qi and heat the phlegm as the treatment of the great law. The drugs represent apricot kernel, mulberry skin, loquat leaf, arbor, Sophia, Sophia and so on. Qingfei diarrhoea represents medicine for baicaleum Scutellaria, Polygonum cuspidatum and so on. Yellow, bitter almond, mulberry leaf, mulberry leaf, Scutellaria, Polygonum cuspidatum, sophion, santian, gendahu and Hubei are the core drugs. They are compatible with Platycodon grandiflorum, trifoliate orange, Fritillaria thunbergii, Melon Wilt, aster, 100, gypsum and so on. The background pneumonia is a common respiratory system disease in pediatrics, which seriously endangers children's health. The WHO lists it as 3 of the world. It is one of the most important pediatric diseases. According to the statistics, the proportion of viral pneumonia is rising in children's acute lower respiratory tract infection. As one of the most important pathogens, respiratory syncytial virus can cause bronchiolitis, bronchopneumonia, interstitial pneumonia, and so on. Respiratory syncytial virus (respiratory syncytia). L virus, RSV) the pathogenesis of infection has not been completely clear, and the current lack of safe and effective vaccines and drugs for targeted prevention and treatment. Chinese medicine has a definite advantage in the treatment of children's respiratory virus infection because of its syndrome differentiation, soft effect and less side effects. Professor Wang has studied two children's viral pneumonia. For more than ten years, according to the characteristics of the disease and the key pathogenesis, Jinxin oral liquid was developed as an effective prescription for the treatment of viral pneumonia. It has the function of Xuan lung opening and closing, clearing heat and eliminating phlegm and relieving cough and asthma. A large number of clinical and experimental studies have shown that it can significantly resist RSV infection and regulate the immune function. The important effective component of Scutellaria baicalensis has a broad spectrum of antiviral activity. However, as with many experimental studies of traditional Chinese medicine, there may be many defects, such as single, independent and non synchronous indexes, which are difficult to fully reflect the mechanism of drug action. Therefore, it should be systematized and holistic if the therapeutic effect is discussed in depth. Metabonomics is an important part of system biology. When the organism is stimulated by various external factors, it can instantly, sensitively and truly express the response and regulation of the whole function of the organism. As a systematic research method, it takes the whole metabolism of the body as the research object and dynamic postgraduate. After an object is stimulated or disturbed, the variety and quantity of its endogenous metabolites can be found from a more comprehensive perspective to discover the real mechanism of the drug and the material basis for its function. Therefore, the research group adopts the metabonomics method to try to clarify the effect of Jinxin oral liquid and baicalein on the treatment of RSV infection. Objective to study the metabolic characteristics of RSV pneumonia BALB/c mice plasma, urine, alveolar lavage fluid, spleen tissue and cells, and then explore the intervention effect of Jinxin oral liquid and baicalein on RSV pneumonia mice and the possible metabolic regulation mechanism. Methods RSV nasal inhalation method infected BALB/C mice. Do not give the intervention of Jinxin oral liquid and baicalein, and set up normal control group, collect the mice plasma, urine, alveolar lavage fluid and spleen tissue, the pathological pathological analysis of lung tissue to observe the pathological changes of lung. After RSV infection 1.5-2h, baicalein treatment, 24h after liquid nitrogen quenching, with water methanol and chlorine Gas Chromatography-Mass Spectrometer (GC-MS) was used to analyze the overall metabolic changes in the plasma, urine, spleen tissues and cells of mice after preprocessing of the above mice and cell samples. The ultra high performance liquid chromatography ion trap mass spectrometry (Ultra Performance Liquid) was used. Chromatography-LTQ/Orbitrap-Mass Spectrometer, UPLC-LTQ/Orbitrap-MS) study the changes of metabolic spectrum in mouse alveolar lavage fluid, using the data collected by principal component analysis (principal component analysis, PCA) and orthogonal partial least squares discriminant analysis (Orthogonalpartial least squares-discriminant analysis, OPLS-DA) analysis Select potential plasma, urine, spleen, alveolar lavage fluid and biomarkers in cell, analyze related metabolic pathways, explain the possible metabolic regulation mechanism of Jinxin oral liquid and baicalein on RSV pneumonia. Results the lung tissue lesion of 1.RSV infected BALB/c mice is mainly located in the interstitial area of the lung, and the pulmonary interstitial multifocal inflammatory cells can be seen in the lungs. Infiltration (+ +), mainly monocyte, lymphocyte, alveolar wall mild hyperemia (+), and alveolar wall thickening. After the treatment of Jinxin oral liquid and baicalein, the pulmonary congestion, edema, and inflammatory infiltration of.2. Jinxin oral liquid were alleviated in different degrees (1) plasma: normal group, RSV pneumonia model group and Jinxin oral liquid treatment OPLS-DA analysis in the plasma of the mice showed that the three groups could be completely separated, without cross and overlap, the model parameters R2Y=0.934, Q2=0.889, identified and screened 6 potential biomarkers, respectively, lactic acid, urea, glutamine, 1,5- dehydrated sorbitol, glucose, peanut four eNIC acid.
