Traditional Chinese medicine (TCM) with the characteristics of holistic view and treatment based on syndrome differentiation, has rich clinical experience thousands of years and demonstrates promising effects to cure complex disease. However, due to the features of multi-component, multi-target and synergistic effect existed in TCM, the effective substances and mechanisms of action are not clear, the qualities of TCM are out of control, and scientific and correct assess system is waiting to be established. The network pharmacology is a novel subject based on the construction of multi-layer networks of disease-phenotype-gene-drug to predict the drug targets in a holistic view, and promote efficiency of drug discovery. Methodologically, network pharmacology integrated the notions of comprehensive research and systematic assessment which agree with the characteristics of holistic view and treatment based on syndrome differentiation in Chinese medicine. Our paper reviewed the challenge and chance within the modernization of TCM, the concept and technology of network pharmacology, and its preliminary application in investigation of TCM. The theoretical system of network pharmacology is emphasized, and the potential prospect of its application in modernization in TCM is focused.

MicroRNAs (miRNAs) are small non-coding RNA molecules with 21 to 24 nucleotides in length, which can regulate post-transcriptional gene expression by interacting with the 3' untranslated regions of the target mRNAs. MiRNAs are widely expressed in eukaryotic cells and involved in a variety of biological processes, such as in the development, differentiation, proliferation, and apop-tosis of cells. They also play essential roles in cell cycle regulation, migration, and tumor development. MicroRNA expression varies in different human tumors and is considered a powerful potential biological indicator in the development, diagnosis, treatment, and progno-sis of cancers. Breast cancer is one of the most common malignancies, and miRNA expression has been found to be differentially ex-pressed in various types of breast cancer. The expression and function of some miRNAs involved in breast cancer development, metasta-sis, and treatments are briefly summarized in this review.

Aim To identify the GABA transporter subtypes and to find its new associated member at the blood brain barrier.Methods Labeled by in vitro infusion of magnetic beads through carotid arteries,the brain microvessels without intact neural cells were sorted in magnetic fields,and identified by RT PCR.The homologous primer of GAT superfamily and the tRNA from isolated brain microvessels were used in the RT PCR to amplify target DNA.The PCR products were isolated by polyacrylamide gel electrophoresis(PAGE) and cloned, sequenced rospectively.The sequences were screened in dbEST of Genbank by Blast.Results Seven DNA bands were isolated from RT PCR products of isolated brain microvessels by PAGE. B3,B5 complete sequences were highly homologous with rat partial GAT 2 and BGT 1 respectively,B7 complete sequence was highly homologous with rat partial TAUT. The other 4 EST of B1(Accession No:CF358965), B2(CD568346), B4(CF358966) and B6(CD568347) were submitted to dbEST,they were homologous with some sequences in Genbank,but were not homologous with GAT members.Conclusion GAT 2 and BGT 1 of GAT and TAUT were localized at the blood brain barrier which might be responsible for the GABA transport across the blood brain barrier.The genes and their functions of 4 EST associated with GAT need to be clarified.

In recent years,gastrointestinal microbiota and fecal microbiota transplantation(FMT)has gained rapidly development.The recent studies demonstrated that FMT has obvious clinical efficacy and safety on the treatment of clostridium difficile infection,inflammatory bowel disease and other diseases in adult.The present article will discuss the efficacy of FMT in treating digestive diseases in children.This review summarizes therapeutic advances in FMT,latest FMT therapies and presents the potential of FMT therapeutics in gastrointestinal and extra-intestinal conditions in children.

Telomerase, as a factor of tumour's happening and development, is a kind of cell element not existing or with low activity in normal cells. Moreover, the activity of telomerase is a common channel for cell's immortalization and deterioration, and is also the main factor in cloning tumour and developing malignant turnour. Therefore, the tumour gene therapy focusing on telomerase has become the new target of present study of tumor.This therapy has greater prospects on clinical application than the past tumour gene therapy simply directing at one cancer gene.

Chronic diarrhea in children is often accompanied by malnutrition,growth disorders,immune dis-function and repeated infection due to deferment diarrhea and malabsorption of nutrients, which could influence the physical and mental development of children. The etiology and pathogenesis of chronic diarrhea are complex. The causes of chronic diarrhea are different in children with different ages,different regions and countries.

The tight junction of intestinal epithelium plays an important role in maintaining the function of intestinal barrier and regulating the cell differentiation. The intestinal epithelial cells interact with neighboring cells and the extracellular matrix and then affect the epithelial barrier as well as the proliferation, polarization, and apoptosis of cells. As an important cell junction, the tight junction of intestinal epithelium participates in a series of signal transduction pathways including the classic cyclic adenosine monophosphate-protein kinase A-cyclic adenosine monophosphate response element-binding, inositol trisphosphate, Ras-mitogen-activated protein kinase, phosphatidylinositol 3-kinase, and in some special pathways including zonula occludents protein 1-associated Y-box factor,cyclin related protein, phosphorylation, and methylation. Furthermore, regulations of gene and protein expression of the tight junction are also complex, while disorders of such regulations may lead to clinical diseases, such as disruption of the intestinal barrier, refractory infection, and even cancers. This article reviews the research advances in gene expressions, related signal transduction, and self-regulation in the tight junction of intestinal epithelium.

Objectives To study the clinical characteristics and early diagnosis of infant with both alpha 1 antitrypin deficiency (α1-ATD) and biliary atresia (BA). Methods The clinical characteristics, serum biochemical parameters, gene mutations and treatment of one infant with both α1-ATD and BA was reported. Related literatures about liver disease caused by α1-ATD were reviewed and analyzed. Results The infant was characterised with neonatal cholestasis, hepatomegaly, elevated serum ALT, AST, total bilirubin (TB), direct bilirubin (DB) and γ-glutamyltransferase (γ-GT) and absence of bile secretion from the duodenal drainage tube. BA was conifrmed by laparotomy and pathological examination and Kasai′s operation was performed. Further, the infant was confirmed by SERPINA 1 gene mutation analysis, which leads to the diagnosis of α1-ATD. The case of infant with both alpha 1 ATD and BA has not yet been reported at home and abroad. According to the literatures, children with α1-ATD were characterized with cholestasis, hepatomegaly, hypoproteinemia, high serum ALT and AST, coagulation disorders caused by vitamin K 1 deifciency and hepatic dysfunction. Prognosis was poor without early diagnosis and treatment. Conclusions For infant cholestasis, a lot of auxiliary examinations should be performed to identify the etiology of cholestasis. Gene analysis could help differential diagnosis. Prompt diagnosis and early treatment are the key to improve the survival rate and prognosis.
