Objective To observe the interventional effect of Compound Kusanqi Capsules on the apoptosis of colonic mucosal cells in rat model of ulcerative colitis (UC).Methods The rat model of UC was established by administrating dinitrochlorbenzene (DNCB), alcohol and acetic acid. The model then was intervened by Compound Kusanqi Capsules in high dose, middle dose and low dose respectively. The curative effect was observed through detecting the expressions of modulin Bcl-2, Bax, Fas and FasL of colonic mucosal cells in the model.Results After the intervention for 15 days the expressions of Bcl-2, Bax, Fas and FasL of colonic mucosal cells were improved in varying degrees in the groups of high-dose, mid-dose and low-dose Compound Kusanqi Capsules, which had significant difference statistically compared with those in the model positive control group (P<0.01 or P<0.05).Conclusion Compound Kusanqi Capsules has the regulation effect on the apoptosis of colonic mucosal cells in rat model of UC.

Objective:To investigate the association between glutathione S-transferase pi (GSTP1) gene polymorphism and toxici-ties related to high-dose methotrexate (HD-MTX) in children with acute lymphoblastic leukemia (ALL). Methods:GSTP1 genotypes and allelic frequencies in 51 children with ALL were determined by Nest PCR, denaturing gel gradient electrophoresis (DGGE), and DNA sequencing. HD-MTX adverse reactions were analyzed using the National Cancer Institute Common Toxicity Criteria (NCICTC). Results:We identified three SNPs of GSTP1, including rs1695 (A313G), rs1138272 (G439T), and rs4891 (T555C). The wild types, het-erozygous types, and homozygous types of GSTP1 rs1695/rs4891 polymorphisms were detected in 32 cases (62.7%), 16 cases (31.4%), and 3 cases (5.9%), respectively. GSTP1 rs1695/rs4891 polymorphisms included only one heterozygous type and one homozygous type. The allele frequencies of the three SNPs were 21.6%, 2.9%, and 21.6%. The AG+GG/TC+CC genotype of GSTP1 rs1695/rs4891 was associated with decrease in the odds of peripheral hemoglobin (OR=0.25, 95%CI=0.06-1.00, P=0.049). The AG+GG/TC+CC genotype of GSTP1 rs1695/rs4891 in standard and intermediate-risk ALL children was significantly correlated with higher odds of gastrointesti-nal toxicity (OR=0.125, 95%CI=0.02-0.78, P=0.026). Conclusion:GSTP1 rs1695 (A313G)/rs4891 (T555C) gene polymorphism is as-sociated with the reduction of peripheral hemoglobin in ALL children and with the odds of gastrointestinal toxicity in standard and inter-mediate-risk ALL children who receive high-dose methotrexate.

Objective To compare the heart function and observe the clinical prognosis of dilated cardiomyopathy(DCM) in children treated with combination of prednisone and azathioprine and high dose intravenous immunoglobulin(IVIG).Methods From Jan.1998 to May 2004,20 children who met the diagnostic criteria of DCM were divided into 2 therapeutic groups(groupⅠ,groupⅡ) according to the time of hospitalization.On the basis of traditional congestive heart failure(CHF) therapy,the children in groupⅠwere treated with immunosuppressive therapy(prednisone plus azathioprine) and the children in groupⅡ were treated with high dose IVIG.The course of treatment was 6 months for all children.Heart functions in all children were evaluated and echocardiographic parameters including left auricular diameter(LA),left ventricular end diastolic diameter(LV),left ventricular ejection fraction(LVEF) and cardiac index(CI) were measured before and after therapy,respectively.All children were followed up for 1 year to observe survival rate(%).The findings were analyzed by t test and ?~2 test.Results The percentage of heart function increased from Ⅲ-Ⅳ toⅠ-Ⅱin groupⅠ,which was lower than that in groupⅡ(P

OBJECTIVETo discuss the feasibility of vascular bundle implantation combined with allogeneic bone marrow stromal cells (BMSCs) transplantation in treating rabbit femoral head osteonecrosis and bone defect, in order to explore a new method for the treatment of femoral head necrosis.

METHODSThirty-six New Zealand rabbits were randomly divided into three groups,with 12 rabbits in each group. Bilateral femoral heads of the rabbits were studied in the experiment. The models were made by liquid nitrogen frozen, and the femoral heads were drilled to cause bone defect. Group A was the control group,group B was stem cells transplantaion group of allograft marrow stromal,and group C was stem cells transplantation group of allograft marrow stromal combined with vascular bundle implantation. Three rabbits of each group were sacrificed respectively at 2, 4, 8, 12 weeks after operation. All specimens of the femoral heads were sliced for HE staining. Furthermore ,vascular density and the percentage of new bone trabecula of femoral head coronary section in defect area were measured and analyzed statistically.

RESULTSIn group C,new bone trabecula and original micrangium formed at the 2nd week after operation; new bone trabecula was lamellar and interlaced with abundant micrangium at the 8th week;at the 12th week,the broadened,coarsened bone trabecula lined up regularly,and the mature bone trabecula and new marrow were visible. At the 2nd week after operation,there was no statistical significance in the percentage of new bone trabecula of femoral head coronary section in defect area between group B and C. While at 4, 8, 12 week after operation, vascular density and the percentage of new bone trabecula of femoral head coronary section in defect area of group C was higher than that of group B.

CONCLUSIONAllogeneic bone marrow stromal cells cultured in vivo can form new bone trabecula, and can be applied to allotransplant. Vascular bundle implanted into the bone defect area of femoral head necrosis could improve blood supply, and promote the formation of bone trabecula.
