Objective: To investigate the inhibitory effects of Curcumin on A? generation in vitro and explore its potential mechanisms involing BACE1 and PPAR?.Methods: Plasmids APPswe and BACE1-mychis were transiently co-transfected into SHSY5Y cells by LipofectaminTM2000,then treated with Curcumin at 0(control Group),1.25,5.0,20.0 ?mol/L for 24 hr,or with Curcumin at 5 ?mol/L for 0,12,24 and 48 hrs for the time course assay.RT-PCR was performed to measure the endogenous levels of BACE1 mRNA and PPAR?.Western blot were used to detect the protein expression of BACE1 and PPAR?.The major cleavage product——A?40 and A?42 was detected by ?-amyloid 1-40 or 42 Colorimetric ELISA assay.Results: The mRNA level and protein level of BACE1 were decreased obviously in a dose-and time-dependent manner after treated with Curcumin in the cell line(P

Alzheimer's disease (AD) is a common progressive degenerative disease of the central nervous system. It's also a main cause for dementia in presenium and senectitude. In the past few years, the discoveries in vitro expansion of neural stem cells (NSCs) indicate a new way for recovery and replacement of damaged neurons as well as reconstruction of the neural circuit, and offer a useful future therapy for AD. There are two main promising approaches in NSCs replacement therapy. They are endogenetic approach, inducing proliferation and differentiation of endogenetic NSCs, improving self-repair of central nervous system, and exogenous approach, ransplantation of exogenous tissue and promoting proliferation of endogenous NSCs. However, it may not become truth before the mechanism of NSCs' proliferation, migration, differentiation and it's integration with the host tissues to be elucidated.

Comrade LU Zhi-jun, a famous surgeon and acupuncture expert, was a leading cadre in health field with outstanding achievements, and a leader of western medicine doctors learning traditional Chinese medicine in the Chinese Communist Party, and also he was a main establisher of The China Academy of Chinese Medical Sciences and a founder of TCM scientific researches and integrated Chinese and western medicine in new China. The present paper reviews the course of LU Zhi-jun in learning and applying acupuncture and moxibustion therapy and a part of works carried out in faithfully implementing our party's policies for uniting Chinese and Western medicine, and in development of TCM including acupuncture and moxibustion in past tens years.

Micronucleus ( MN) assay as a routine examination for genotoxicity has been widely used.The testing specimens were taken from bone marrow and extended from blood and tissues.In addition to testing genotoxicity of drugs, it is also applied in disease diagnosis for genetic mutation, evaluation of curative effectiveness and disease prevention. Moreover, MN assay is also an important safety indicator for drugs and health foods registration.This review will discuss the staining method of MN test and its application in the field of diseases and virology.

This study aimed at exploring the modeling and identification method of autoimmune POF by the ZP3 polypeptide with the provision of scientific basis for the prevention and treatment of POF.B6AF1 female mice,the hybridization of A/J male mice and C57BL/6 female mice,was immunized by zona pellucida polypeptide fragments.Then,the mice estrous cycle was detected by vaginal exfoliated cells Pasteur's staining.After the 14-day modeling,the mice model was identified on the 7th and 14th day,respectively.Ovarian tissue morphology and anti-zona pellucida antibodies immunofluorescence change were detected by H&E staining and ZP3 immunofluorescence staining.Serum hormone levels of E2 and FSH in the mice were tested by ELISA,with the combination of estrous cycle,ovarian tissue morphology and anti-zona pellucida antibodies immunofluorescence change to judge the success of the POF mice model.It was found that ZP3 polypeptide immunized mice appeared the disorder of estrous cycle after 14 days,so did the marked inflammation observed by ovarian biopsy,a clear transparent zone by ZP3 immunofluorescence staining,and the decrease of serum E2 declined and the increase of serum FSH by ELISA.However,no significant change was found on the 7th day in the modeling.In conclusion,ZP3 polypeptide induced autoimmune POF mice model was established successfully,featuring high incidence and simple method and laying a foundation for the further study of autoimmune POF.

OBJECTIVE: To discuss the challenges and opportunities for traditional pharmacies in digital network time. METHODS: Aiming at the problems occurring in the work of pharmacy and pharmaceutical care, we analyzed the meaning and deep impact of the using of network information technology in pharmacy .RESULTS: It is clear that the drug supply ori- ented pharmacies should be transformed to pharmaceutical care oriented pharmacies. It is very important to use computer high text to handle pharmaceutical information efficiently.CONCLUSION: The digital networks can extend the work of pharma- ceutical care in space and time and provide an opportunity to the development of pharmacies.
