Objective To incubate the rat neural stem cells with specific inhibitor (PD98059) of MAPKK/MEK to clarify the effect of MAPKK/MEK-MAPK/ERK signaling pathway in neural stem cells (NSC).Methods NSCs derived fiom E15-16 rats were isolated and cultured.After treated with different concentration of PD98059,they were subjected to the detection of cell proliferation,Nesn'n, BrdU and β-tubulin-Ⅲ by WTS-8 assay,immunofluorescent staining or Western Blot respectively.Results PD98059 had an effect on the survival,proliferation and differentiation of NSC at a concentration-dependent manner.The viability of the NSC was significantly decreased than the control (P＜0.05),whereas the numbers of BrdU-positive and β-tubulin-Ⅲ positive cells were notably fewer than the control (P＜0.05) after incubated with the higher concentration of PD98059.The ERK expression was blocked by PD98059 at a concentration-dependent manner.Conclusion The MAPKK/MEK-MAPK/ERK signaling pathway played a vital role in the survival, proliferation and differentiation of NSC.

Objective To observe the change of nitric oxide(NO) content and explore its cell source following brain ischemic injury. Methods We established the model of transient global brain ischemia/reperfusion (IR) in rat. The concentration of NO and its cell source were investigated by detection of NO content, NDP histochemical staining, double label technique of immunofluorescence and stereological analysis after brain ischemia. Results (1)The content of NO increased at 12 h and peaked on days 1～3 after IR. The content of NO decreased gradually on the 5th day after IR. (2)The density of NDP positive cells increased and peaked on the 1st day after IR. The positive cells distributed mainly in the temporal cortex, hippocampus and periventricular zone after IR. The positive cells were found to reduce gradually or disappear on the 14th day after IR. (3)Few NDP positive and GFAP immunofluorescence positive cells were found to coexist at the early period of IR(1～3 d). The percentage of coexisting cells was 10%～15%. Conclusion The content of NO increases at the early period after ischemic brain injury. The main cell type to produce NO is neuron.

Objective To investigate the relationship between single nucleotide polymorphism (677C→T) of methylenetetrahydrofolate reductase and Alzheimer′s disease(AD) in south China Han people. Methods By applying polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP), MTHFR 677C→T mutation was detected in 45 AD patients and 48 healthy controls. Results The frequency of MTHFR 677C→T mutation of patients showed no significant difference to that of healthy controls (P > 0.05). There is no statistic significance between AD group and controls in C, T gene frequency(P>0.05). But T gene frequency is higher in AD group than in control group. Conclusion MTHFR C 677T is not the pathogenic factor for AD, but could have some effects on AD.

Objective:To investigate the migration and odontogenesis of rat dental pulp cells transfected with adenovirus vector enco-ding cadherin-11.Methods:The dental pulp cells were cultured and transfected with pDC316-mCMV-EGFP-Cadherin-11.Cad-11 protein expression of the cells was examined by immunohistochemistry staining.The odontogenic differentiation of the cells was studied by alizarin red staining and ALP staining.The adhesion and migration of the cells were tested.Results:Transfection of pDC316-mC-MV-EGFP-Cadherin11 promoted Cad-11 protein expression and ALP activity,increased calcified nodule formation(P <0.05),adhe-sion and migration of rat dental pulp cells(P <0.05).Conclusion:Cadherin-11 may promote the odontoblast differentiation and mi-gration of rat dental pulp cells.

Objective To investigate the effect of recombinant human growth hormone on the PingPang Racket flap survival.Methods Every two PingPang Racket flaps were designed on the both sides of 40 adult SD rats's back.The pedicle size was 1.0 cm × 1.0 cm,while the flap size was 3.0 cm in diameter circular.Longitudinal axis of flap was perpendicular to the center line of the rats back,to which the distance from proximal pedicle was about 1 cm.The flaps on the left side served as Ⅰ group,and the other side served as Ⅱ group,which were subdivided into Ⅰa and Ⅰb,Ⅱa and Ⅱb,respectively.And there were 20 rats in each subgroup.On the flap surfaces in group Ⅰ,it was 6 uniform injection poinsts,subcutaneously injecting with rhGF (the dose was 0.1IU · Kg-1 · d-1) for 7 days from the beginning of operation,that were designed.It goes the same way to the group Ⅱ,while normal saline was instead of rhGF.In subgroup Ⅰa and Ⅱa,the flaps were generally observed every day.The percentage of the flap survival area was determinated 7 days after operation.In subgroup Ⅰb and Ⅱb,specimens were collected at the distal end of flap at intraoperative(before injecting rhGF)and 1 st,3rd,5th,7th day after operation.Immunohistochemistry and enzyme-linked immunosorbent were applied to examine the expression of TGF-β1 and CD34,and the microvessel density of the flaps was calculated.Results According to the 7 days' observation after the surgery,the flap survival area percentage of subgroup Ⅰa was (97.00 + 2.12) ％,which was significantly higher (P ＜ 0.05) than that of subgroup Ⅱ a,whose was (81.00 +3.43)％.On 1st,3rd,5th and 7th day postoperatively,the expression of TGF-β1,CD34 in both subgroup Ⅰb and Ⅱb were elevated and reached peak on the 5th day.Content of GF-β1 and CD34 in Ⅰb were 1571.40 ± 13.32 pg/ml and 60.40 ±0.32 pg/ml,respectively,and in Ⅱb were 691.43 ± 11.06 pg/ml and 20.43 ± 0.06 pg/ml.At the same point of time,the expression of TGF-β1,CD34 were significant higher in Ⅰb subgroup than that in Ⅱb (P ＜ 0.05).In subgroup Ⅰb and Ⅱb,the number of microvessels increased on postoperative 1 st,3rd,5th and 7th day,especially on 3rd,5th and tended to be stable at 7th day.At the same point of time,the number of microvessels in Ⅰb was always higher than that in Ⅱb (P ＜ 0.05).Conclusion Subcutaneous injection of rhGH on flaps can enhance the expression of TGF-β1,CD34,promote microvascular generation of the flap tissue directly or indirectly,and also improve the survival of PingPang Racket flaps.

As an important branch of systematic biology, metabonomics is an emerging discipline following genomics, proteomics and transcriptomics. It focuses on the quality and quantity changes of the small molecular metabolites in appointed physiological or pathological state, and provides important informa?tion for studies of diseases mechanism, clinical early diagnosis and prognosis prediction. Compared with tra?ditional clinical diagnostic method ( single index) , metabonomics method can more comprehensively analyze metabolites changes in the body. This review introduces the metabonomics and summarizes its application in thyroid diseases.
