Traditional Chinese medicine (TCM) has a good reputation for preventing or healing diseases in clinic due to its higher efficacy, minor toxicity and abundant resources. Screening bioactive components in TCMs is not only crucial for clarifying their action mechanisms, but also the basis of their safety and quality control. TCM is characterized by multiple components, multiple targets and multiple mechanisms, however the complex composition of TCM makes it difficult to study the therapeutic material basis which has become the bottleneck in the process of its modernization and internationalization. Recently, with the rapid development of modern technologies and the unceasing progress of various disciplines, multidisciplinary approach, such as analytical chemistry, chemistry of TCM, pharmacology, cell biology, systems biology and bioinformatics has been successfully applied to the study of TCM. Multidisciplinary approach realizes the communication and interaction of multi-discipline, and accelerates the research and development of TCM. This review summarizes the application of multidisciplinary approach which may have certain potential of bringing new thoughts to TCM research and provide references for screening and identification of therapeutic material basis of TCMs.

OJECTIVE: To explore the changes of serum IgE and tryptase caused by anaphylactic shock rats and discuss the relation to PMI and preservative environment of corpse and specimen. METHODS: Rats were used for establishing anaphylactic shock models and randomly divided into room temperature group, refrigeration group, frozen group, manual hemolysis group, specimen preservation group. And the control group was also established. The blood samples were collected after rats were sacrificed. The degree of hemolysis was graded according to the color of the upper layer of the serum. The mass concentration of IgE and tryptase in each group was detected by ELISA. RESULTS: The levels of serum IgE and tryptase in anaphylactic shock dead rats were higher than that of the control group. Room temperature and frozen made obviously differences on the levels of serum IgE and tryptase with various PMI. The levels of serum IgE and tryptase in refrigeration group showed relatively stable. The levels of serum tryptase and IgE were elevated with differently increasing hemolysis. The levels of serum IgE and tryptase showed no obvious changes during the specimen kept under different temperature conditions for 25 days. CONCLUSION Serum IgE and tryptase obviously increased in anaphylactic shock rats. However, the levels were influenced by PMI and environmental temperature, especially under the conditions of room temperature and frozen.

Near-infrared (NIR) was used as rapid analysis method to identify the sulfur fumigated Puerariae Lobatae Radix. NIR spectra of the cross-sectional and longitudinal selection of samples were acquired. Principal component analysis was conducted. The samples were randomly selected. The different pretreatment methods were compared. Discriminant models were established for every type of spectra to calculate the recognition rate. The orthogonal test and nonparametric test were used to test data normality. The result showed that absorbance values of different sections were different due to the different structure, and the raw spectra were analyzed by PCA method. The result founded that the cumulative contribution rate was arrived at 99.2% while the PC numbers were arrived at 3. The pretreatment method based on the MSC + 1D + Savitzky-Golay was the best to establish the model. For the 50 models constructed with cross-section and longitudinal spectra and total spectra, the recognition rate were (94.4 ± 0.66)%, (94.4 ± 0.66)%, (95.3 ± 0.65)%, respectively, and no difference was observed. The NIR method could be used to identify the sulfur fumigated Puerariae Lobatae Radix.

To obtain the caries experience and, plaque accumulation severity and pit and fissure morphology in first permanent molars in 7-8 children in Wuhan, as a reasonable prediction of caries risk and preventive attention in the future, a convenient sample of five primary schools in the vicinity of the Wuhan University School and Hospital of Stomatology was drawn. Two calibrated examiners orally examined all present grade 2 children in the classroom, using standard caries plaque and tooth morphology criteria. Dental caries was scored at enamel (D(2)) and dentine (D(3)) for tooth and surface level. Independent variables were age, gender and school. Data analysis used analysis of variance and t-test. The sample comprised 1 043 7- and 8-year-olds. The prevalence of dental caries in permanent dentition was 8.7% and in primary dentition, 68.7%. Mean Decayed, Missing, Filled Teeth/S (DMFT/S) scores were 0.11 and 0.14, respectively. Mean dmft/s scores were 2.8 and 5.0. The d-component constituted 75% of the d(3)mft index, while enamel carious lesions constituted 36% of the total number of carious lesions (d(2,3)-component). Prevalence of medium and deep pits and fissures was 84.6%. Prevalence of medium and severe plaque accumulation was 67.4%. Prevalence of dental caries in the deciduous and permanent dentitions of 7- to 8-year-old children was high. Deep pits and fissures in high caries risk children should be sealed.

Near-infrared (NIR) diffuse reflectance spectroscopy was used to analyze the impact of multi-class particle size of Chinese material medica (CMM) based on the spectral characteristics in overtone and combination region. Several types of CMM (60, 80, 100,120 mesh) were subjected to NIR spectra analysis. Spectral reproducibility was examined after sample repackage. The result showed that the effects of particle size on the NIR spectra were different according to different bands, in the combination region and first combination-overtone region. Spectroscopy intensity was proportional to the particle size and influence of particle size was greater as the wavelength increased. While in the second combination-overtone region, it was inversely proportional to particle size. To the sampling loading error, the result indicated that when the mesh number was larger than 60 mesh, the error was small. The appropriate particle size was clarified to guarantee the accuracy and reliability of NIR diffuse reflectance spectroscopy in CMM.
