Objective To investigate photo-protective effect of NS398 on above cells damaged from UV irradiation.Methods HaCaT cell and HaCaT keratinocytes were incubated in the culture medium supplemented with different concentration of NS398 for 2h before diffierent dosages of UV irradiation.MTT assay was used to detect cell proliferation and cellular activity:Fluorospectrophotometer assay was used to measure the change of ROS level in the cells which were UV-mediated.Resuits After irradiation with UV,proliferation and cellular activity of HaCaT cells were decreased(P<0.05);NS398 reduced the generation of ROS in cells induced by UV irradiation apparently and the cell apoptotic rate was dependent on the concentration of NS398. Conclusion NS398 might play an important role in the treatment of UV irradiation injury by decreasing the generation 0f ROS in cells after UV irradiation and increasing the survival ability of HaCaT cells.

Objective To establish embryonic stem cells (ESC) that can express green fluorescent protein (CFP) and differentiate them into neurons. It would provide tagging neurons for clinical transplantation to cure neural system diseases. Methods ESC (R1) was transfeeted with a plasmid containing the GFP by electroporation. A transgeuic cell line was obtained after selection with G418. The ESCs were characterized by AKP staining. Monolayer differentiation method was used to induce neural differentiation derived from GFP-ESC and immunofluorescence method was used to identify Tuj1 positive cells. Results There was no significant difference(X2=3.14,P0.05) in transfect rates between liposome and electroporation (65% vs 79%). The AKP staining of GFP-ESC was positive. GFP-ESC could be differentiated into neural cells. Conclusions These results show that ESC expressing GFP has been estabhshed, which can be differemiated into neurons.

ABSTRACT:Objective To explore the risk factors for maternal adverse pregnancy outcomes.Methods An unmatched case-control study based on hospital was performed.Univariate and multivariate Logistic regression were used to analyze the related factors of maternal adverse pregnancy outcomes,including general condition,history of fertility,abnormal symptoms and diseases during pregnancy.Results Univariate analysis results showed that high education level of gravida might be the protective factors of adverse pregnancy outcomes.The risk factors for adverse pregnancy outcome might include advanced maternal age,intensive workload,frequent pregnancy,history of spontaneous abortion,severe morning sickness,and sickness during pregnancy or progestation.Multivariate Logistic regression analysis showed that high education level of gravida (OR=0.63,95% CI:0.50-0.80)was the protective factor of adverse pregnancy outcomes;severe morning sickness (OR=2 .1 3 ,9 5% CI:1 .6 3-2 .7 9 )and sickness during progestation (OR=2.25,95% CI:1.06-4.77)were the risk factors for maternal adverse pregnancy outcomes.Conclusion The level of maternal education should be improved.We should attach great importance to preventive education and thorough treatment of severe morning sickness. Couples should be encouraged to have physical examination before marriage and pregnancy.Corresponding pregnancy care guidance should be given to pregnant women with different physical conditions so as to effectively reduce the occurrence of adverse pregnancy outcomes.

Objective To investigate whether functional Wnt-?-catenin signaling is present in activated hepatic stellate cells (HSC),and the effect of blocking this signaling on activation of HSC. Methods?-catenin expression in HSC was examined by immunocytochemistry.Wnt signalings in HSC-T6 were assessed using a T cell factor (TCF)-dependent luciferase reporter gene (pTOP- FLASH) assay.Wnt signalings in HSC-T6 were blocked by transfecting with a dominant negative TCF (dnTCF) expression plasmid,then the expression of alpha smooth muscle actin (?-SMA) and collagen typeⅠwere examined by Western blot.Results?-catenin staining was positive in the nuclei of HSC-T6.Luciferase activity in the cells transfected with pTOPFLASH was significantly higher than that in the cells transfected with pFOPFLASH (P

Hyperthermia is a means of adjuvant therapy, which have a sensitizing effect to radiotherapy and chemotherapy. In recent years, the molecular biology, cell and animal experimental research of tumor thermochemotherapy progressed very quickly, which provide theoretical foundation and guidance for us to further develop hyperthermia combined with chemotherapy in clinical trials. In this paper, the studies with the mechanism of thermo-chemotherapy treatment of tumor, different ways of thermochemotherapy and commonly used drugs in thermochemotherapy are reviewed.

Objective To explore the influence of intestinal trefoil factor (ITF) on interleukin-6(IL-6) in neonatal rat with necrotizing enterocolitis(NEC) ,and to discuss the protective machanism of ITF on NEC.Methods Thirty-two neonatal rats were divided randomly into four groups,group A as control group,group B as NEC group,group C as NEC+NS 0.2 mL group,group D as NEC+ITF 0.2 mg group.NEC model of neonatal rats were established.On the 4th day,all the subjects were put to death.Intestinal tissue within the boundary of ileum and cecum was obtained to observe histological changes.Other intestinal tissue was treated into homogenate.After the homogenate was centrifuged,supernates were used to test the density of IL-6.Results The density of IL-6 significantly decreased in group A,D than those in group B and C (Pa0.05).The pathological lesions indicated that intestinal tissue necrosis was severe in group B and C,which was graded as 3 points,but obviously lessen in group D,which was graded as 1 point,with ITF interfering.Conclusions Intestinal inflammation is ameliorated after ITF are injected hypodermically or intraperitoneally.ITF may provide a brand-new way for the therapy of NEC in neonatal rats.
