Objective To investigate the effects of lipopolysaccharide(LPS) on Src-suppressed C Kinase Substrate(SSeCKS) in cultured astrocytes. Methods Purified astrocytes were randomly divided into three groups:control group,singly stressed and multiple stressed groups.The expression of SSeCKS was detected by Real time RT-PCR and Western blotting,while immunocytochemistry was used to investigate the subcellular localization of it. Results Real time RT-PCR indicated that,after 12 hours incubation,both 100 ?g/L and 1mg/L LPS were able to elevate the levels of SSeCKS mRNA compared with control group,while 1mg/L LPS did not have a stronger effect than 100 ?g/L.Western blotting analysis showed 100 ?g/L LPS significantly increased the expression of SSeCKS.In time response experiments,the levels of SSeCKS expression enhanced three hours after the stimulation,peaked at the sixth hour,coincident with its rapid phosphorylation,and remained high until the 24th hour.Immunocytochemistry suggested a perinuclear translocation of SSeCKS,while the PKC inhibitor RO-31-8220 blocked it.Conclusion In cultured astrocytes,LPS can enhance the expression of SSeCKS,increase its phosphorylation level and change its subcellular localization.These effects are correlated with the PKC pathway,which indicates SSeCKS might participate in the signal transduction of inflammation in cultured astrocytes.

BACKGROUND:Previous tudies have shown that the anti-aging effects of stem cel s with lycopene are more significant, and can also significantly improve the aging body immune function.
OBJECTIVE:To investigate the anti-aging effects of human umbilical cord mesenchymal stem cel s combined with lycopene on the aging beagles.
METHODS:Sixteen aging beagles (6-7 years old) were randomly divided into two groups:aging control group and aging treatment group;young beagles (3-4 years old) were chosen as young control group. In the aging treatment group, human umbilical cord mesenchymal stem cel s combined with lycopene was given;while in the other two group, an equal amount of DMEM/F12 cel culture medium and sunflower oil was given. Each dog's general conditions were observed regularly during the whole progress. The changes of superoxide dismutase,
malondialdehyde, glutathione peroxidase in the serum were detected at regular time of the whole process, and the structure changes of each organ were observed at 24 weeks of treatment.
RESULTS AND CONCLUSION:(1) Before treatment, the levels of superoxide dismutase and glutathione peroxidase in the aging control and treatment groups were lower than those in the young control group (P<0.05), while the malondialdehyde content was higher than that in the young control group (P<0.05). However, there was no significant statistical difference between aging control and treatment groups (P>0.05). (2) For the aging treatment group at 24 weeks of treatment:the beagle fur became clearer and smoother, motility was strengthened, appetite became better;and the activity of superoxide dismutase in serum at 8 to 24 weeks of treatment increased significantly compared with before treatment (P<0.05), the activity of glutathione peroxidase significantly increased from 6 weeks (compared with treatment before, P<0.05), the malondialdehyde content decreased significantly from 4 weeks of treatment to the completion of the experiment (compared with before treatment, P<0.05). (3) After the experiment, the microscopic observation showed that compared with the aging control group, the tissues and organ structures of the aging treatment group were al clear, had no inflammatory infiltrates, no obvious necrosis and fibrosis lesions. These results were mainly consistent with the observations of young control group. The above results show that umbilical cord mesenchymal stem cel s combined with lycopene therapy on the natural aging beagles may enhance the activities of antioxidant enzymes, reduce malondialdehyde content, and their combination also can repair tissue structures and promote the functions, which has obvious anti-aging effects.

Preoperative neoadjuvant therapy has become a hot topic in the treatment of locally advanced esophageal cancer (EC) in recent years. Accumulated evidences have demonstrated that neoadjuvant therapy combined with surgery could significantly improve the survival of patients with locally advanced EC compared with the surgery alone. The importance of neoadjuvant chemotherapy (nCT) and neoadjuvant chemoradiotherapy (nCRT) has been widely recognized and included in the guidelines. For locally advanced EC, especially for esophageal adenocarcinoma, both nCT and nCRT can significantly prolong the survival of patients than the surgery alone. Currently, whether the supplement of radiotherapy can bring more benefits to patients compared with nCT alone remains a hot topic. Besides, it is generally believed that the operation should be performed at 2-8 weeks after neoadjuvant therapy, whereas the optimal time interval remains debated. In this article, the research progress and existing problems in the preoperative neoadjuvant treatment of locally advanced EC were summarized.
