TPX2(targeting protein for Xklp2)is a microtubule-associated protein in a new family of vertebrate spindle pole components.TPX2 is diffusely distributed all over the nucleus during the cell cycle phases S and G_2 and play important roles in mitotic spindle formation.TPX2 over expression was found in a variety of malignant tumors,that are asssociated with the centrosome amplification,aneuploidy,cell transfor- mation and the biological behavior of tumor.Blocking the expression of TPX2 can inhibit the growth of tumor cells.TPX2 may serve as a new candidate target for tumor therapy.The study progress of its structure and function,expression levels in cell cycle,molecular mechanism etc.was reviewed.

OBJECTIVE: To investigate the effects of Gypsum Fibrosum and Gypsum Fibrosum Preparatum in promoting granulation. METHODS: The wounds of muscle layer were produced in rats by using surgical operation. Two round wounds, with diameter about 1.5 cm, were cut at the depilatory area of two sides of the back of each rat, with an interval of 2 cm, deep to muscle layer, and the thickness of the knife wound of muscle layer was about 0.15 cm. Forty SD rats with the wounds were randomly divided into 4 groups: untreated group, beifuji-treated group, Gypsum Fibrosum-treated group and Gypsum Fibrosum Preparatum-treated group, with 10 rats in each group. Then the wounds were sprinkled with powders of Gypsum Fibrosum and Gypsum Fibrosum Preparatum, or sprayed with beifuji solution, respectively. The healing state of granulation tissues of the wounds was observed at the eighth and fourteenth day respectively. RESULTS: The number of fibroblasts, the number of capillary tubes and the area of capillary tubes in granulation tissue of wounds in the Gypsum Fibrosum Preparatum-treated group were significantly higher than those in the untreated group and Gypsum Fibrosum-treated group (P<0.01). There were no statistical differences between the Gypsum Fibrosum Preparatum-treated group and the beifuji-treated group. However, Gypsum Fibrosum-treated group showed no obvious differences compared to the untreated group (P>0.05). CONCLUSIONS: Gypsum Fibrosum Preparatum can accelerate the formation of collagenoblast and micrangium in wounds, and the proliferation of granulation tissues, thus promoting the skin wounds to healing. The effect of Gypsum Fibrosum is changed after being calcined, and Gypsum Fibrosum Preparatum has obvious effect in promoting granulation.

Objective:To study the mechanisms of neutrophil elastase (NE) induced expression of respiratory mucin MUC5AC. Methods:Using gene recombination techniques,four luciferase reporter gene plasmids containing different length of human MUC5AC gene promoter were constructed.Site-directed mutagenesis technique was used to establish mutants of Sp-l and NF-?B site in MUC5AC gene promoter; the relative luciferase activities were detected in the transfected human pulmonary A549 cells. Results:Series of luciferase reporter gene containing different sequences of human MUC5AC promotor were constructed successfully.NE could increase the expression of luciferase reporter gene plasmid containing -1300bp,-689bp and-324bp version of MUC5AC promoter in the transfected A549 cells (P

Objective: To research the effects of Zuogui Pill on the gene expression profile of regenerate hepatic tissue in MSG-liver regeneration-rat.Methods: MSG-liver regeneration-rat models were copied;therapy group were given Zuogui Pill(5g/kg) by intragastric administration.Rats were executed at the 5th day after operation,and the regenerate liver tissues were frozen by liquid nitrogen.1176 gene chips of gene expression profile correlated to cell differentiation and multiplication were adopted to observe the changes of gene expression profile in the regenerate liver tissues.Results: There were 292 differential expression genes in therapy group compared with model group(20 genes were up-regulation expressed and 272 genes were down regulation expressed).Conclusion: Zuogui Pill has significant effects on the gene expression profile of regenerate hepatic tissue in MSG-liver regeneration-rat,and most of the genes are down regulation expressed.The result hints that Zuogui Pill could influence the liver regeneration by regulating the gene expressions of MSG-live regeneration-rat.Down regulation of the gene expressions of regenerate hepatic tissue in MSG-liver regeneration-rat possibly is one of the important molecular mechanisms of Zuogui Pill in nourishing liver and kidney.

Objective To investigate the significance of serum IP-10 levels in different types of diabetic patients. Methods Serum IP-10 level in 78 cases with type 1 diabetes,49 cases with type 2 diabetes and 33 cases of healthy controls was measured with ELISA assays. Type 1 diabetic patients were divided into classic type 1 diabetes (n=39) and latent autoimmune diabetes in adults (LADA,n=39) according to their disease process,and they were also divided into autoimmune type 1 diabetes (n=58) and idiopathic type 1 diabetes (n=20).Type 2 diabetic patients,according to carotid intima-media thickness (IMT),were divided into patients with (n=24) or without atherosclerosis (n=25). Results 1) Serum IP-10 levels were not statistically different among type 1 diabetes,type 2 diabetes and healthy controls. 2) Serum IP-10 concentrations in autoimmune type 1 diabetes with positive islet autoantibody were higher than those in healthy controls(184.96?104.48pg/ml vs 146.10?74.61pg/ml,P=0.03);while there were no difference in type 1 diabetes with variable disease durations. 3) No difference in IP-10 levels was found between type 2 patients with(173.5?69.6pg/ml) and without atherosclerosis (188.5?79.7 pg/ml). Conclusions Serum IP-10 level is augmented in autoimmune type 1 diabetes.
