2.Role of SDF-1/CXR4 axis in treatment of cerebral ischemia with endothelial progenitor cells
International Journal of Cerebrovascular Diseases 2009;17(10):792-796
Studies in recent years have demonstrated that stromal cell-derived factor-1 SDF-1/CXCR4 axis plays an important role in the process of angiogenesis. The expression of SDF-1 in ischemic tissue increases during cerebral ischemia. It binds to CXCR4 receptor on the surface of endothelial progenitor cells EPCs, and thus promotes bone marrow-derived EPC mobilization, proliferation, and migration to the ischemic areas and homing. EPCs differentiate into mature endothelial cells in the ischemic region, promote the formation of new blood vessels, and thus irrlprove the blood supply to ischemic tissue. This article reviews the effect of SDF-1/CXCR4 axis in the treatment of cerebral ischemia with EPCs.

Objective To explore the effect of combined use of schizophrenia combined with psychological intervention on benzene exposure to workers. Methods A total of 106 workers were randomly divided into observation group and control group. The 106 workers were randomly divided into observation group and control group. The workers were randomly divided into observation group and control group. 53 patients were given the observation group combined with the psychological intervention, given the control group placebo, 3 months after the intervention to compare the two groups of workers blood parameters, oxidation-antioxidant indicators and genetic damage indicators. Results The WBC and PLT were significantly increased after treatment (P<0.05 or P<0.01), while MDA and MN were significantly decreased (P<0.05). Conclusion Leucosonurn has some protective effects on blood system damage, oxidative damage and cytogenetic damage caused by exposure to benzene, and the combination of psychological intervention is beneficial to the early prevention of benzene poisoning.
5.Relationship between reduced folate carrier gene methylation and methotrexate resistance
International Journal of Pediatrics 2014;41(3):267-270
Tumor recurrence and drug resistance impact patients'therapeutic effect and prognosis seriously.In recent years,it has been found that epigenetic changes are involved in drug resistance.DNA methylation is one of the ways of epigenetic.DNA methylation of drug metabolism enzyme gene can affect gene's expression,leading to drug resistance.Methotrexate(MTX),a folic acid antagonist,is the most widely used drug in the treatment of malignant tumors,such as leukemia,osteosarcoma,head and neck cancer,and so on.Reduced folate carrier(RFC) is the main transporter cartier of MTX,and gene methylation is related to tumor cells'resistance to MTX.This paper reviews the role of RFC,relation of RFC methylation and methotrexate resistance and the factors of RFC methylation.

Objective To research the important of prenatal diagnosis and effect of intervention to fetal hydrothorax. Methods The cases of fetal hydrothorax (n=5) were obtained from the Shengjing Hospital,China Medical University between December 2014 and May 2015. All pregnancies were uncomplicated, excluded congenital organic and chromosomal abnormalities during prenatal diagnosis and with a 37 average gestational weeks. The case 1, 2, 4 were unilateral hydrothorax and the case 3, 5 were bilateral. We performed an antenatal thracocentesis to case 1, 2, 3. In case1, the hydrothorax increased rapidly after 5 days, and the patient underwent a cesarean section and ex utero intrapartum treatment (EXIT);in case 2, the fetal heart rate was decreased to 40-50 bpm suddenly during thracocentesis, and we performed an emergent cesarean section and EXIT for the patient; in case 3, the patient underwent thracocentesis and a meanwhile cesarean section and EXIT procedure. We performed a conservative management to case 4, 5, the hydrothorax resolved spontaneously during the pregnancy and after birth, both patients underwent cesarean section. Results All fetuses were survived, the neonates of case 1, 2 and 3 underwent assited mechanical ventilation, thoracic close drainage, then discharged after hydrothorax resolved and feeding tolerance;in case 4, there was no respiratory distress and hospital treatment;in case 5, the neonate underwent assited mechanical ventilation and conservative management, the hydrothorax has resolved gradually. Conclusions The prenatal diagnosis and antenatal intervention (thracocentesis) may play an important role in fetal hydrothorax treatment. In clinical, we should choose different plan according to the gestation weeks and classification of hydrothorax of the patient.
