Currently,XB130 as a newly discovered characterized adaptor protein ,it has been implicated as a substrate and regulator of many intracellular signal transduction ,such as FAK/SRC,PI3K/Akt and MEK-ERK signaling and so on.It has been found that XB130 is high expression in many cell lines ,for instance thyroid carcinoma,osteosarcoma,gastric cancer,esophageal cancer and breast cancer etc .The mechanism of XB130 in tumor is becoming increasingly attention .XB130 is recently attributed to be a new oncogene ,and plays important roles in cell pro -liferation,cell survival and tumorigenesis .A deeper understanding of these mechanisms may lead to the discovery of XB130 as an important mediator in tumor development and as a novel therapeutic target for cancer.

BACKGROUND: The proliferation and differentiation of mesenchymal stem cells (MSCs) lack of regulatory functions. Following combining with suitable vectors, MSCs cannot highly effectively proliferate and differentiate, which are keys to prevent MSCs entering the clinic. It is of great importance to effectively regulate the differentiation of stem cells into osteoblasts using pulse electromagnetic field.OBJECTIVE: To investigate the differentiation of mouse MSCs into osteoblasts in vitro following stimulation of pulse electromagnetic field.DESIGN, TIME AND SETTING: The cytological in vitro controlled study was conducted at the Laboratory of Department of Orthopaedics, Puai Hospital of Tongji Medical College, Huazhong University of Science and Technology from May 2004 to October 2007.MATEIRALS: Totally 20 BALB/C mice were supplied by the Experimental Animal Center of Tongji Medical College. Pulse electromagnetic field deviser was designed and made by the Department of Electric Machine, Naval University of Engineering.METHODS: Mouse bilateral femur was sterilely isolated. BMSCs were harvested by the Percoll density gradient centrifugation,and purified and proliferated by the adherent method. Cells at the third passage (2×10~7/L) were incubated in a 6-well plate, and then divided into 4 groups. Cells in the blank control group were incubated in the complete medium. Cells in the pulse electromagnetic field underwent pulse electromagnetic field radiation of 50 Hz, sinusoidal wave, and 1 mT, twice a day, once 30 minutes, with an interval of 12 hours, totally 10 days. Cells in the osteogenic induction group were incubated in the complete medium, supplemented with dexamethasone, sodium glycerophosphate and VitC. Cells in the pulse electromagnetic field + osteogenic induction group were subjected to the same pulse electromagnetic field radiation and then incubated in the complete medium.MAIN OUTCOME MEASURES: The differentiation of BMSCs was measured.RESULTS: Results of alkaline phosphatase staining showed that cells were negative in the blank control group, but weakly positive in the pulse electromagnetic field group, positive in the osteogenic induction group, and strongly positive in the pulse electromagnetic field + osteogenic induction group 10 days following intervention. Compared with the blank control group,absorbance value of type I collagen immunohistochemistry was significantly greater in the osteogenic induction group, pulse electromagnetic field + osteogenic induction group (P < 0.05, P < 0.01).CONCLUSION: Pulsed electromagnetism fields of 50 Hz, waves of sine, with the intensity of 1 mT could promote alkaline phosphatase and type I collagen expression and enhance the differentiation of mouse BMSCs into osteoblasts in vitro.

Radiation-induced lung injury (RILI) is a common complication in thoracic cancer patients through radiotherapy, which can be divided into the early-stage radiation-induced pneumonitis (RP) and late-stage radiation-induced lung fibrosis (RILF). At present, glucocorticoids are mainly adopted in the clinical treatment of RP. However, there has been no effective medical treatment for RILF. RILF patients will eventually die from respiratory failure. The exact mechanism of RILI remains unclear. Current studies have proposed that its possible pathogenesis might consist of genetic heterogeneity, oxidative stress and cell damage. In this review, studies related to the pathogenesis of RILI were summarized.

It is difficult for medical students to understand electrocardiogram theory. The sec-ond clinical medical college of Wuhan University has explored clinical pathophysiology and therapy (CPPT) pattern in electrocardiogram education. Basic medical knowledge and clinic medical knowl-edge are combined with electrocardiogram theory to reinforce students ' comprehension and attract theit interest in order to obtain better teaching effect. Drawing themselves, analyzing electrocardiogram sys-tematically and memorizing theory with figure is aimed at solving forgetful problems. In addition, the problems such as lack of conformable teaching material, professional teaching teams and objective mode of examination are raised, and the solutions are explored under CPPT pattern.

Objective To understand the epidemic situation of Hepatitis B of the children and the situation of Hepatitis B vaccine injection in Maanshan city so as to provide the basis for the development of Hepatitis B vaccination strategy or adjustment in all of the people. Methods Two-stage sampling method was designed to survey 978 children under the age of 15 in 8 villages, with 3~5 ml of venous blood brawn and HBVM detected by ELISA. Results HBsAg positive rate of the children under the age of 15 was 10.12% in 1991 and, compared with the present rate at 0.92%, there was a significant difference. The protection rate of Hepatitis B vaccination was 90.91%. HBsAb positive rate of the children under the age of 15 was 40.49%, and the distribution was balanced among regional, urban and rural areas. With the in crease in age, the trend of Hepatitis B antibody levels declined, but the 1~5 age group had lower peak. The survey rate of Hepatitis B vaccine injection of the children under the age of 15 was 91.82%, and the report rate was 87.89%. The regional difference for them was significant. With the in crease in age, the rate of Hepatitis B vaccine injection declined for the survey and the report in all of the children under the age of 15. Conclusions The effect of Hepatitis B Control for 16 years is very significant in the city. It is necessary to administer charge-free Hepatitis B vaccination for the newborns and to strengthen the Hepatitis B vaccination in flowing children.

Aim To study protective effects of Total of flacone C(TFC) against cerebral ischemia-reperfusion injury.Methods Four-vessel occlusion method was used to make acute cerebral ischemia-reperfusion model. Rats were initiated by ischemia for 30 min followed by 40 min of reperfusion.The electroencephalography(EEG) during cerebral ischemia and reperfusion was recorded.The level of intracellular calcium ion concentration([Ca~(2+)]i) in cerebral cells after ischemia was measured by using a Ca~(2+) indicator Fura-2/AM.Superoxide dismutase(SOD),Glutathione peroxidase(GSH-Px),Lactate dehydrogenase(LDH),nitric oxide Synthase(NOS) activeties and Malondialdehyde(MDA),Nitric Oxide(NO)contents in the ischemia cerebral cortex were measured.Results TFC can improved the EEG change,significantly attenuated the decrease of the intracellular calcium ion concentration([Ca~(2+)]_i), remarkly increased GSH-Px,SOD and NOS activities in the cerebrum,inhibit the decrease of LDH activity and NO,MDA contents.Conclusion TFC has protective effects on cerebral ischemia-reperfusion injury,the mechanism may be related to attenuating free radical,[Ca~(2+)]i overload and NO.

Objective To observe the protective effect of total flavone of Camellia (TFC)against cerebral ischemic injury.Methods Decapitation method and close hypoxia method were used to observe the effect of TFC on anoxic tolerance of mice and step down test was used to observe the effect of TFC on learning and memory; after ischemia, the content of malondialdehyde (MDA)and nitric oxide (NO)and the activity of lactate dehydrogenase (LDH)were detected. Rat models with acute incompletely cerebral ischemia were established by means of ligating right common carotid arteries and effect of TFC on cerebral water volume, permeability of cerebral vessels and cerebral histopathological changes were also observed.Results TFC prolonged the grasping time after decapitation and the survival time after anoxia in mice, and improve the learning and memory during the step down test. TFC decreased MDA and NO contents, counteracted the de creases of LDH activities in the mice cerebral cortex, reduced the water volume and permeability of cerebral vessels in ischemic rats and improve the cerebral hitstopathological changes. Conclusion TFC has protective effects against cerebral ischemic injury and the mechanism may be related to the inhibition of free radicals and NO production.
