Streptococcus gordonii is a nonpathogenic gram-positive commensal bacterium and component of the normal microbial flora of the human oral cavity. It is suitable to be as a mucosa vaccine vector due to its special bionomics. knowing the bionomics of Streptococcus gordonii,the general expressing system,and the application of it in mucosa vaccine,will provid important reference for the further development of its mucosa vaccine.

To construct expressing vector carrying esat6 gene and express this protein in Streptococcus gor-donii GP251. esat6 gene was amplified by PCR with specific primer from genome of Mycobacterium tuber-culosis (MTB)H37Rv. Inserted esat6 into the pMD18-T vector by T/A clone to get recombinant vector pMD18-esat6. Then digested pMD18-esat6 with restriction enzyme, esat6 was cloned to vector PSMB104 and expressed in Streptococcus gordonii GP251. The expression of esat6 protein was detected by Tricine-SDS-PAGE and Western-blot, ELISA technique was also used to detect its secretory volume. Re-striction endonuclease, PCR, Tric ine-SDS-PAGE and Western-blot confirmed that esat6 gene was cloned into expressing vector successfully, and a 10 kD protein secreted in Streptococcus gordonii GP251, this pro-tein has a good immunogenicity. The expression vector of esat6 gene was constructed, and esat6 protein ex-pressed in Streptococcus gordonii1 successfully, it will be benefit for future study.
6. Na+-glucose cotransporter inhibitor for treatment of diabetes
Academic Journal of Second Military Medical University 2011;32(4):435-438
Sodium glucose co-transporter (SGLT) is one of the transporters responsible for the resorpcion of glucose, and inhibition of its activity can decrease the resorption of glucose. Human SGLT is mainly composed of SGLT1 and SGLT2. Due to the specific distribution and the high efficiency of SGLT2, SGLT2 inhibitor is a potential new strategy for treatment diabetes. Abundant animal experiments and clinical trails have found that SGLT2 inhibitor can greatly lower the blood glucose and help to lose weights. However, the current researches about SGLT2 inhibitor are still very limited both in depth and in broadness; problems concerning the safety, efficacy and indication of SGLT2 inhibitor still need to be further studied.

Ginseng and its effective components are famous for their influence to enhance human immunity, regulate endocrine and antioxidant action. However, the different effects of different components are not clear. In this study, Wistar rats were used to study the effects of main components of ginseng, including total ginsenoside, panaxadiol saponins, panaxtrol saponin and ginseng polysaccharide. The results showed that the effects of panaxadiol saponins and ginseng polysaccharide on improving animal immune organ weight, plasma interleukin 2 (IL-2), interleukin 6 (IL-6), plasma gamma-interferon (IFN-γ), tumor necrosis factor alpha (TNF-α) were better than that of the other groups. Total ginsenoside and panaxtrol saponin can effectively increase the concentration of spleen NK cells (NKC) while panaxadiol saponins and ginseng polysaccharide can significantly increase the concentrations of rat plasma adrenocorticotrophic hormone (ACTH), corticosterone (CORT) and thyroid stimulating hormone (TSH). As for the effect of increasing organization nitric oxide (NO) and superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA), total ginsenoside is better than that of other groups. In brief, different components in ginseng possess different effects on enhancing immunity, regulating endocrine and resisting oxidation. Panaxadiol saponins and ginseng polysaccharide are better in enhancing immune, and total ginsenoside shows advantages in resisting oxidation and stress.

International Eye Science 2014;(7):1356-1357
AlM: To observe the treatment efficacy of eyelid herpeszoster with external use ganciclovir ophthalmic gel.METHODS:A total of 77 patients were randomly divided into treatment group and control group. ln the treatment group, ganciclovir ophthalmic gel was topical coated on the basis of antiviral drugs, while the control group was coated with conventional acyclovir ointment and antiviral treatment.
RESULTS: The cure rate was 95% in the treatment group, and the control group was 83% after 10d treatment. The difference was significant.
CONCLUSlON: The efficacy of ganciclovir ophthalmic gel treated eyelid herpes zoster is obvious.
