Objective To study the molecular pathogenesis of non -syndromic deafness in a Chinese family . Methods Clinical materials and DNA sample were obtained from the non -syndromic family with autosomal reces‐sive deafness .The exons and the flanking splicing sites of GJB2 and SLC26A4 were tested in all family members by PCR and direct sequencing .Results There were four deafness patients in the family ,and three of them had the same clinical phenotypes ,including prelingual profound sensorineural hearing loss and enlarged vestibular ,while the re‐mained one only presented to be prelingual profound sensorineural hearing loss without malformation of temporal bone .One type of GJB2 mutation and 3 different types of SLC26A4 mutations were identified in the family .The proband(Ⅲ -1) ,her sister(Ⅲ -2) ,her mother(Ⅱ -4) and her father(Ⅱ -3) carried different biallelic mutations which were SLC26A4 c .919 -2A > G/p .H723R ,p .Q413R/c .919 -2A > G ,p .Q413R/p .H723R and GJB2 c . 235delC/c .235delC ,respectively .Conclusion Different from most reported deafness families with the same molecu‐lar etiology in each one ,interestingly ,the pathogenies were different among all affected members in this family . They were caused by different biallelic mutations of SLC26A4 or GJB2 .

OBJECTIVE:Comparing the components in decoctions of raw Fructus Viticis and its processed products.METHODS:The methods of UV - spectrophotometry,TLC, etc. were used for the qualitative and quantitative analysis of decoctions of raw Fructus Viticis and its processed products.RESULTS:The content of total flavone in the steamed Fructus Viticis decoction was the highest and that in the carbonated Fructus Viticis decoction was the lowest;the amount of water extract substances of honey- processed Fructus Viticis was the highest and that of carbonated Fructus Viticis was the lowest .CONCLUSION: It is suggested that there exist significant differences in intrinsic quality among various processed products of Fructus Viticis.

Treatment by way of pasting TCM on acupoints has a long history and the clinical efficacy is determined. In this article, based on the concept of TCM wholism and meridian theory, the mechanism of acupoint pasting therapy was expounded from the aspects of medicine effects on local stimulation of the body, meridian conduction, medicine transdermal absorption. Combining with the research hot spots of modern medicine transdermal delivery system, metabolomics, and efficacy material, this article proposed a new study mode of systems biology of TCM.

At present, the disjointing situation is generally present between "systemic"and "local", "macro" and "micro", " process" and "activity evaluation" in the study of traditional Chinese medicine (TCM). An urgent task for the modernization of TCM is to establish new strategies and methods which can reflect the overall characteristics of TCM. The introduction of integrative pharmacology provided a feasible approach to solve the problem of the fragmentation of TCM. Internet-based computation platform method was adopted in this study to explore the active molecular mechanism of Mylabris in the treatment of colorectal cancer. Based on the analysis of the functional integration of internet-based computation platform V1.0 version software, the "core components-key target- main pathway" multidimensional network of Mylabris in treatment of colorectal cancer disease was constructed to explore the potential molecular mechanism of Mylabris in treatment of colorectal cancer from multiple perspectives. The results showed that Mylabris can treat the colorectal cancer and the mechanism might be associated with amino acid metabolism, NF-κB signaling pathway, immune system, endocrine system, nervous system, and chemokine signal transduction pathway, epithelial cell signaling in helicobacter pylori infection, T cell receptor signaling pathway, B cell receptor signaling pathway and so on.
