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 analyze the prevalence and factors of birth defect on perinatal fetuses in Hubei province.Method The prevalence of birth defect on perinatal fetuses delivered in 28 weeks or more was analyzed in Hubei surveillance hospital of birth defect during 2001-2005 year.Results The prevalence rate of birth defect on perinatal feruses from 2001 to 2005 year was 107.39 per 10 000,and increased significantly than that in 2001 year 81.07 per 10 000(?2=39.505 P

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.

With the extensive use of information technology and the development of big data technology, the traditional treatment methods for cancer are not meeting our needs.The application of medical large data has now changed our tumor treatment model profoundly, but also brings a deeply cognition to the nature of malignant tumor.Development of medical big data analysis and management technologies are driving malignancy treatment model fromindividual treatment era into the precision medicine era, which allows us to change the prediction, diagnosis, treatment and monitor of malignancy.There are also a variety of challenges to resolve.

Objective To establish a method for determination the contents of six phendic acids in Mailuoning injection by HPLC at same time. Methods Separation was performed on a Kromasil-C18 (4.6 mm? 250 mm, 5 ?m) column with mobile phase consisting of 0.1% phosphoric acid-water and Acetonitrile with gradient elute at the flow rate of 1 mL/min. The UV detection wavelength was set at 327 nm and the column temperature was set at 25 ℃. The sample size was 20 ?L. Results The standard cures of neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, caffeic acid, 3,5-Dicaffeoylquinic acid, 3,4- Dicaffeoylquinic acid were linear within the contentration range of 0.010 90～0.544 8 ?g (r=0.999 9), 0.024 06～1.203 2 ?g (r =1), 0.011 06～0.552 8 ?g (r =1), 0.015 94～0.796 8 ?g (r =1), 0.009 104～0.455 2 ?g (r =1), 0.010 37～0.518 4 ?g (r=1) respectively. And the recovery rates of them were 101.06%, 100.22%, 101.54%, 99.42%, 100.21%, 101.65% respectively. Conclusion The method appeared to be simple, reliable, accurate and can be used to determine the contents of six phendic acids in Mailuoning injection.

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.

Objective To investigate the effects of cardiopulmonary bypass (CPB) with mild hypothermia on the pharmacodynamics of rocuronium in infants undergoing cardiac surgery.Methods Fifty ASA Ⅰ or Ⅱ and NYHA class Ⅰ or Ⅱ infants,aged 6 months-3 yr,weighing6-15 kg,undergoing repair ofventricular septal defect or atrial septal defect under CPB,were randomly divided into 2 groups ( n =25 each):profound hypothermia group and mild hypothermia group.The target temperature was controlled at 28-30 ℃ during CPB in profound hypothermia group,and at 32-34 ℃ during CPB in mild hypothermia group.Neuromuscular block was assessed by TOF-stimulation of ulnar nerve using with TOF-Watch accelerometer.Anesthesia was induced with midazolam O.1 mg/kg,propofol 2 mg/kg,fentanyl 6-8 μg/kg and rocuronium 600 μg/kg,and maintained with intermittent iv boluses of fentanyl and midazolam.The patients was tracheal intubated and mechanically venti1ated when the maximal depression of T1 was achieved.PETCO2 was maintained at 30-40 mm Hg.When T1 returned to 75％ of the control twitch,rocuronium 200 μg/kg was injected intravenously.The onset time,maximal N-M block time,clinical muscle relaxation time,and recovery index were recorded before CPB,during CPB and after CPB.Results Compared with profound hypothermia group,the onset time,maximal N-M block time and clinical muscle relaxation time were significantly shortened during CBP in mild hypothermia group ( P ＜ 0.05).Conclusion Compared with profound hypothermic CBP,mild hypothermic CBP can shorten the onset time and muscle relaxation time of rocuronium in infants undergoing cardiac surgery.
