Parkinson's disease is a commonly encountered central nervous retrograde affection in elder persons. According to the theories of traditional Chinese medicine, Parkinson's disease is characterized by deficiency in the Ben (root) and excess in the Biao (branch). The Ben (root) is insufficiency of liver and kidney and deficiency of qi and blood; and the Biao (branch) is wind, fire, phlegm and stasis. Good therapeutic effects have been obtained by treatment based on syndrome differentiation, treatment with specific prescriptions and acupuncture. The further study on literatures, standardized criterion of symptoms differentiation and therapeutic effect determination as well as the screening and further research on the effective prescriptions and herbs should be paid more attention, meanwhile, the integration of herbs and acupuncture will be conducive to raise the therapeutic effect.

Patent documentation is a kind of high-value scientific literature, which has caught the attention of more and more scholars. In this paper, the World Traditional Medicine Patent Database (WTMPD) was used to retrieve patents of the traditional medicines used in the treatment and prevention of influenza worldwide in the past 30 years. A total of 2 423 patents were further screened by a series of processes. Finally, multi-angle analysis was carried on the dataset to form a patent analysis report on traditional anti-flu drugs. From the analysis, we found that China had a rapid increase in the number of patent applications, which was in the leading role in the world, though the number of PCT applicant from China is relatively low. A large amount of applicants from the USA, Japan, and Korea have entered into China. Pharmaceutical company is the core group of patent applicant, who had applied a lot of quality patent about their products to protect their commercial interests. Honeysuckle, licorice, isatis root, forsythia and skullcap are five kinds of herbs, which have been most frequently used in anti-influenza patents.

Synthetic biology of traditional Chinese medicine (TCM) is a new and developing subject based on the research of secondary metabolite biosynthesis for nature products. The early development of synthetic biology focused on the screening and modification of parts or devices, and establishment of standardized device libraries. Panax notoginseng (Burk.) F.H.Chen is one of the most famous medicinal plants in Panax species. Triterpene saponins have important pharmacological activities in P. notoginseng. Squalene epoxidase (SE) has been considered as a key rate-limiting enzyme in biosynthetic pathways of triterpene saponins and phytosterols. SE acts as one of necessary devices for biosynthesis of triterpene saponins and phytosterols in vitro via synthetic biology approach. Here we cloned two genes encoding squalene epoxidase (PnSE1 and PnSE2) and analyzed the predict amino acid sequences by bioinformatic analysis. Further, we detected the gene expression profiling in different organs and the expression level of SEs in leaves elicited by methyl jasmonate (MeJA) treatment in 4-year-old P notoginseng using real-time quantitative PCR (real-time PCR). The study will provide a foundation for discovery and modification of devices in previous research by TCM synthetic biology. PnSE1 and PnSE2 encoded predicted proteins of 537 and 545 amino acids, respectively. Two amino acid sequences predicted from PnSEs shared strong similarity (79%), but were highly divergent in N-terminal regions (the first 70 amino acids). The genes expression profiling detected by real-time PCR, PnSE1 mRNA abundantly accumulated in all organs, especially in flower. PnSE2 was only weakly expressed and preferentially in flower. MeJA treatment enhanced the accumulation of PnSEI mRNA expression level in leaves, while there is no obvious enhancement of PnSE2 in same condition. Results indicated that the gene expressions of PnSE1 and PnSE2 were differently transcribed in four organs, and two PnSEs differently responded to MeJA stimuli. It was strongly suggested that PnSEs play different roles in secondary metabolite biosynthesis in P. notoginseng. PnSE1 might be involved in triterpenoid biosynthesis and PnSE2 might be involved in phytosterol biosynthesis.

Background and purpose: Phosphatase and tensin homologue deleted on chromosome 10 (PTEN) gene is a kind of tumor suppressors, which has been reported to be underexpressed in endometrial carcinoma (EC) tissues by several reports. However, the biological effects and possible mechanisms of PTEN on EC have been known less. In this study, we tried to investigate the effects and possible mechanisms of PTEN on the invasion and migration of endometrial carcinoma cells and to provide a potential target for endometrial carcinoma therapy. Methods:The recombinant plasmid pIRES2-ZsGreen1-PTEN was rebuilt by gene recombination technology;The plasmid was transferred into HEC-1B cells and the cells transfected with pIRES2-ZsGreen1 plasmid were used as control;The expression of PTEN was observed by fluorescence microscope and Western blot assay;Cell migration and invasion was determined by the wound healing assay, transwell migration and invasion assays respectively;The Western blot analysis was performed to detect the expression of ATP-dependent tyrosine kinase (AKT), phosphorylated-AKT (p-AKT) and matrix metalloproteinase-2 (MMP-2). Results:The agarose gel electrophoresis showed a stripe of 1.2 kb which was same to PTEN cDNA;The sequence analysis showed the PCR products owned the same sequence with the coding region of PTEN cDNA in GenBank, suggesting the recombinant plasmid was constructed successfully;The green light of cells observed by fluorescence microscope and the Western blot analysis showed the expression of PTEN was upregulated in the cells transfected with the recombinant plasmid, suggesting the plasmid expressed successfully in HEC-1B cells;The wound healing assay as well as transwell migration assay showed ectopic expression of PTEN suppressed cell migration;The invasive capacity of HEC-1B cells was significantly decreased upon transfection with PTEN plasmid compared to control and untreated groups;Moreover, compared with the control groups, the expression of p-AKT and MMP-2 was downregulated, while there was no significant alteration of the expression of AKT. Conclusion:PTEN could suppress cell migratory and invasive ability of endometrial carcinoma cells by suppressing the phosphorylation of AKT followed by the decrease of MMP-2.
