ObjectiveTo study the expression of telomerase of fibroblasts in the formation and development of scar,and to investgate the relationship between the telomerase activity and the formation and development of scar.MethodsExpression of telomerase was detected by immunohistochemical techniques in 18 specimens from granulation tissue,17 keloid,16 specimens from hypertrophic scar,28 specimens from mature scar,32 specimens from normal skin,and SPSS16.0 statistics software was used to analyze the relationship between telomerase and scar.Results It was shown that the positive expression rate of telomerase in the granulation tissue group was 94.4 %,that in the keloid group was 58.8 %,that in the hypertrophic scar group was 18.8 %, and that in the mature scar and in the normal skin was zero. comparisons between groups,in addition to the normal scar group and normal skin group,other groups were statistically significant differences.ConclnsionsScar formation is a process with multi-factor participation,while telomerase activation is an important factor. Detecting telomerase activity in the development process of scar formation may determine the prognosis.Through the control of telomerase activity in the pathogenesis of scar may become a new approach of scar treatment.

Objective To explore the bone marrow stromal cells,anti-late antigen-4 (VLA-4) antibody (aVLA-4),cytarabine (Ara-C) on the proliferation and apoptosis of leukemia HL-60 cells.Methods The experiment was divided into five groups:HL-60 cells were cultured alone (control group),HL-60 cells and stromal cells group (stromal cells group),HL-60 cells + stromal cells + aVLA-4 (antibody group),HL-60 cells + stromal cells + Ara-C group (drug group),HL-60 cells + stromal cells + aVLA-4 + Ara-C group (antibody +drug group).Cell proliferation or inhibition rate was detected by CCK-8 method,the HL-60 cells apoptosis was detected by flow cytometry.The expression of anti-apoptotic gene bcl-2 in HL-60 cells was determined by Western blot.Results After 24 h and 48 h,treatment,the number of the stromal cells group HL-60 cells were higher than that of the control group with significant difference cultured [(7.2±0.3)×1O5/ml vs (5.3±0.4)×105/ml,(8.4±0.2)×105/ml vs (6.8±0.3)×105/m1,P < 0.001],while the HL-60 cell proliferation inhibition rate [(24.3±2.1) %,(37.0±2.6) %,(65.6±3.8) %] and apoptosis rate [(5.7±0.6) %,(8.0±0.5) %,(10.4±0.9) %,(16.5±0.7) %] of antibody group,drug group,antibody + drug group were higher than the control group with a difference of statistically significant (P < 0.05),and the increase of antibody + drug group was most obvious.With the decreasing of the bcl-2 protein expression,which was most the decrease of antibody + drug group was most obvious.Conclusion Bone marrow stromal cells can stimulate the proliferation of leukemia cells,aVLA-4 interference the interaction between stromal cells and leukemia cells can enhance the chemosensitivity of leukemia cells to Ara-C.

Objective To observe the clinical efficacy and adverse reaction of the combination of fiudarabine,cytarabine and granulocytecolony-stimulating factor (G-CSF) (FLAG regime) therapy for refractory and relapsed acute leukemia in children. Methods From 2004 to date, a total of 9 patients with relapsed and refractory acute leukemia patients in our hospital accepted the treatment, in 9 cases 8 cases were AML,1cases were ALL; in 9 cases 5 cases were refractory acute leukemia, 4 cases were recurrent acute leukemia.Results Among the 9 cases,6 cases with 1 cycles of chemotherapy achieved complete remission (CR),CR rate was 66.7 % (6/9); partial remission (PR) rate was 22.2 % (2/9),total efficiency (CR+PR) was 88.9 %.In 6 CR patients 2 underwent hematopoietic stem cell transplantation, are disease-free survival; this regimen' s main adverse reactions were infection,bone marrow depression and gastrointestinal reaction.Conclusion The remission rate of FLAG regimen in the treatment of children with refractory and relapsed acute leukemia is relatively high, adverse reactions were tolerable; the FLAG program is a choice for the treatment of children with refractory and relapsed acute leukemia,which provides the opportunity for subsequent hematopoietic stem cell transplantation.
