ABSTRACT

Steaming is a traditional processing method of traditional Chinese medicine (TCM). In this paper, taking the Collection of Processing Methods of TCM (Ancient Times) as a clue and checking the original herb books, the historical evolution of TCM steaming was sorted out and analyzed from four aspects, including steaming method, steaming variety, quality control method of steaming process, and steaming purpose. The results showed that the steaming method was originated from the Spring and Autumn period and the Warring States period. Afterwards, a total of 56 steaming methods were recorded. The most steamed varieties recorded in Song dynasty were 104, and the most newly added varieties in Song dynasty were 90. The steamed varieties recorded in the processing specifications of southern provinces and cities were higher than those of northern provinces and cities, including 43 in Guangdong province. The quality control of steaming process in Tang dynasty included steaming time, steaming times, softening by steaming, etc. In the Song dynasty, the steamed until aroma and sweet and steaming rotten were increased. In the Ming dynasty, the poisonous drugs steamed until no numbness of tongue and nontoxic was increased, and in the Qing dynasty, steaming and moistening was added. The main purposes of steaming in the past dynasties were recorded as enhancing the tonic effect, moderating the medicinal properties, reducing side effects, etc. In modern times, the purposes of preserving medicinal effects and facilitating storage were increased. From the perspective of the historical process of steam development, the Spring and Autumn period and the Warring States period to the Han dynasty were the embryonic period of steam development, the Southern and Northern dynasties, Tang and Song dynasties were the rapid periods of steam development, and the Ming and Qing dynasties were the prosperous periods of steam development. This paper can provide reference for the research and development of steaming technology.

ABSTRACT

The volatile oil of Curcumae Rhizoma has many active components,which are the key to the quality of Curcumae Rhizoma. Exploring the difference between volatile oil of different kinds of Curcumae Rhizoma facilitates the quality control and rational application of resources. In this study,GC-MS was applied to realize online qualitative and semi-quantitative analysis of the chemical composition spectrum of volatile oil from Curcuma wenyujin( CW),C. phaeocaulis( CP),and C. kwangsiensis( CK). Forty components were identified and their fingerprints were compared and evaluated. Hierarchical cluster analysis( HCA),principal component analysis( PCA),and orthogonal partial least squares discrimination analysis( OPLS-DA) were adopted to analyze the overall and outlier data. The results showed that the whole data could be divided into three kinds according to each analysis mode,and the volatile components of Curcumae Rhizoma vary greatly among species. PCA explored the difference between outliers and the mean value of the group and found that some volatile oils from CW may be greatly affected by the origin. By OPLS-DA,the samples from Zhejiang were able to gather,but those from Guizhou remained isolated,indicating the influence of growing environment on Curcumae Rhizoma metabolites. Based on VIP results combined with the heat map,characteristic volatile oil components of Curcumae Rhizoma from different varieties were screened out: curdione and linalool for CW; 2-undecanone for CP; humulene,γ-selinene,and zederone for CK. The GCMS method established in this study describes Curcumae Rhizoma samples comprehensively and accurately,and the characteristic components screened based on chemometrics can be used to distinguish Curcumae Rhizoma from different varieties and give them unique pharmacodynamic significance,which is fast,convenient,stable,and reliable and supports the rational application of Curcu-mae Rhizoma resources. It is found that the region of origin has great influence on CW,which is worthy of further study.

ABSTRACT

This study aimed to establish a rapid and accurate method for identification of raw and vinegar-processed rhizomes of Curcuma kwangsiensis, in order to predict the content of curcumin compounds for scientific evaluation. A complete set of bionics recognition mode was adopted. The digital odor signal of raw and vinegar-processed rhizomes of Curcuma kwangsiensis were obtained by e-nose, and analyzed by back propagation(BP) neural network algorithm, with the accuracy, the sensitivity and specificity in discriminant model, correlation coefficient as well as the mean square error in regression model as the evaluation indexes. The experimental results showed that the three indexes of the e-nose signal discrimination model established by the neural network algorithm were 100% in training set, correction set and prediction set, which were obviously better than the traditional decision tree, naive bayes, support vector machine, K nearest neighbor and boost classification, and could accurately differentiate the raw and vinegar products. Correlation coefficient and mean square error of the regression model in prediction set were 0.974 8 and 0.117 5 respectively, and could well predict curcumin compounds content in Curcuma kwangsiensis, and demonstrate the superiority of the simulation biometrics model in the analysis of traditional Chinese medicine. By BP neural network algorithm, e-nose odor fingerprint could quickly, conveniently and accurately realize the discrimination and regression, which suggested that more bionics information acquisition and identification patterns could be combined in the field of traditional Chinese medicine, so as to provide ideas and methods for the rapid evaluation and stan-dardization of the quality of traditional Chinese medicine.

ABSTRACT

Colla Corii Asini(Ejiao)is an important Chinese medicine used in China for thousands of years, and is well known for its famous tonic properties. The herbalogical study was detailed carried out based on the naming, habitat, harvesting, processing, medicinal properties and clinical efficacy. The results showed that the name of Ejiao could be traced back to Shennong's Materia Medica, and various names of Lvpi Jiao, Penfu Jiao and Fuzhi Jiao were recorded in other ancient books. In the many intervening centuries, the main materials of Ejiao had been replaced from cow leather before Tang Dynasty to donkey skin in the middle to late Tang Dynasty. This phenomenon could be probably caused by complicated social factors of various periods and different efficacy of Ejiao made by all kinds of raw materials. Ejiao was merely processed with the simple methods before Tang Dynasty, which subsequently improved avariety of methods to enhance the supplementation action. Most importantly, Ejiao has a wide clinic application along with the development of processing theories and methods, which can be found in various Classics, especially in imperial medical case record in Qing Dynasty.

ABSTRACT

As a most important Chinese materia medica, Aconiti Lateralis Radix Praeparata(Fuzi) had been widely used in China for thousands of years. This herbalogical study was systematically performed based on variation characteristics of the naming, habitat, harvesting, processing and properties. The sharp toxicity of Fuzi had been well known since the spring and autumn period in the history, which was much earlier than that its medical properties was understood and applied. Sichuan province was regarded as the geo-authentic region of Fuzi all along, where the best quality goods could be provided for clinic use. The study showed the harvesting time of Fuzi was changing in different periods, and the possible effects were of climate change and artificial planting. The perishable characteris-tics of Fuzi severely limited its storage period; therefore, different kinds of storage methods were effectively used since Tang Dynasty. For thousands of years, Fuzi had been processed with various accessories to reduce toxicity, while simultaneously the study on processing mechanism was on going all the time. Fuzi was widely used in clinical practice to cure Yang depletion syndrome, which was based on its function of enhancing Yang and removing cold. Along with the further study on quality evaluation standard, Fuzi will probably get a much wider range of applications.

ABSTRACT

Objective To detect the expression of human epithelial growth factor receptor 2 (HER-2) in advanced lung adenocarcinoma with epithelial growth factor receptor (EGFR) mutation, and to explore the potential of HER-2 as a therapeutic target for drug resistance in patients with EGFR mutations. Methods HER-2 is commonly expressed in the advanced lung adenocarcinoma with EGFR mutations, mainly in the cell membrane. Results The overexpression rate of HER-2 protein in tissues of advanced lung adenocarcinoma with EGFR mutations was 33.3%(28/84). The overexpression rate of HER-2 protein in patients>50 years of age was 40.3%(27/67), which was significantly higher than that of patients ≤50 years of age [5.9 % (1/17)], the difference was statistically significant (χ2=7.227, P=0.007). The overexpression rate of HER-2 protein in patients with high pathological differentiation [44.4 % (8/18)] was higher than that in patients with poor pathological differentiation [30.3%(20/66)], but the difference was not statistically significant (χ2=1.273, P=0.259). The overexpression of HER-2 protein in patients with EGFR 21 exon mutation [40.5 % (17/42)] was significantly higher than that of EGFR19 exon mutation [25.0%(10/40)], but the difference was not statistical significance (χ2=2.222, P=0.136). Conclusions The overexpression rate of HER-2 protein in advanced lung adenocarcinoma patients with EGFR mutation is high, which is related to the age and tumor differentiation. HER-2 is expected to be a potential therapeutic target for drug resistance patients with EGFR mutations.

ABSTRACT

The infratemporal fossa abscess is an irregularly shaped cavity, situated below and media to the zygomatic arch. It consists of masseter and nervus vascularis, etc. Comparatively speaking, the low position of the infratemporal fossa has almost freed the patient from dental, nasal,ocular and aural source of pain. So facial acupuncture is more likely to cause the infection. But it is also possible that the patient get cryptogenic infection of maxillofacial cavity, the treatment of which needs further study.
