Objective To investigate the effect and hematopoietic reconstitution as well as survival of diffierent kinds of allogeneic hematopoietic stem cell transplantation(allo-HSCT)in the treatment of leukemia.Methods allo-HSCT was used to treat 20 cases of leukemia from March 2003 to July 2006 in my hospital.Twelve of them received allo-PBSCT from HLA matched sibling donors.Four of them received HLA-mismatched unrelated umbilical cord blood transplantation.Three of them received allo-PBSCT from unrelated donors.One of them received bone marrow transplantion from unrelated donors.Results Totally 19 recipients acheived hematopoietic reconstitution.The median time of hematopoietic reconstitution after UCBT was longer than that of HLA matched sibling PBSCT.Seven patients received aGVHD after allo-HSCT,and 4 among them were Ⅰ~Ⅱ degree and 3 cases Ⅲ~Ⅳ degree.Two patients died of relapse,and 3 patients died of GVHD.One patient was puzzled by cGVHD.The others are disease-free survival now.The median time of survival is 30(1~41)months.Conclusion allo-HSCT is effective for the cure of patients with leukemia.UCBT with enough cells and 1~2 mismatched loci is safe and effective for the patients who have no HLA matched sibling donors.

BACKGROUND:As the epiphyseal plate has an important role in the growth and development of femur, the design of internal fixation should avoid the damage to the epiphyseal plate. Therefore, the positioning of pediatric femoral epiphyseal plate is particularly important.
OBJECTIVE:To investigate the biomechanical property of the new femur neck screw internal fixation in treatment of children femoral neck fracture.
METHODS:Twelve femurs were col ected from six fresh children cadavers provided by Dissecting Room of University of South China. After exclusion of bone disease with X-ray film, three new children femoral neck screws and three Kirschner wires with the diameter of 2.0 mm were used for fixation. The biomechanical tests were conducted to detect the axial compression and torsion stiffness.
RESULTS AND CONCLUSION:In the children femoral neck screw group, the axial compression stiffness and torsion stiffness under the torsional torque of maximum 3 N?m were (190.74±20.88) N/mm and (0.18±0.045) N?m/° respectively;(138.95±15.19) N/mm and (0.120±0.036) N?m/° respectively in the Kirschner wire group;there were significant differences in the axial compression stiffness and torsion stiffness between two groups (P<0.05). The results showed that the compressive strength and torsional capacity of the children femoral neck screw were strong than those of Kirschner wire. The experiment suggested that the femoral neck screw for children is a new type of ideal internal fixation device which consist with the anatomical features of children proximal femur and can meet the requirement of children femoral neck fracture with good biomechanical property.

Objective To investigate the relationship between single-nucleotide polymorphisms of IVS13-98G/T of human protection of telomeres 1 (hPOT1) genes and gastric cancer. Methods A total of 168 patients with gastric cancer (gastric cancer group) who had been admitted to Wuwei Cancer Hospital, Wuwei People's Hospital and Liangzhou District Hospital from December 2005 to July 2006 and 156 healthy people (control group) were genotyped by polymerase chain reaction (PCR) and PCR-restriction fragment length polymorphism (PCR-RFLP) method, and the relationship between the distribution of genotypes and the risk faetors of gastric cancer was analyzed. The distribution of genotypes and allele frequency between the 2 groups were compared by chi-square test. Hardy-weinberg equilibrium test was adopted to determine whether the distribution of genotypes and allele frequency were representative. Relative risk and 95% confidence interval were calculated by non-conditional Logistic regression model. Results The frequencies of genotypes GG, GT and TT of hPOT1IVS13-98 G/T were 21.4%, 41.7% and 36.9% in gastric cancer group, and 24.4%, 51.9% and 23.7% in control group. The allele frequencies of G- and T-allele were 42.3%, 57.7% in gastric cancer group, and 49.7%, 50.3% in control group. There was no significant difference in allele frequencies of G- and T-allele between the 2 groups (X~2=3.58, P>0.05). Compared with genotype TT, the relative risks for GT and GG were 0.439 (95% CI: 0.251-0.767, P < 0.05) and 0.514 (95 % CI: 0.264-0.999, P=0.05). There was no influence of different genotypes of hPOT1IVS13-98 G/T, sex, smoking history, family history of cancer on gastric cancer. Conclusion Single-nucleotide polymorphisms of IVS13-98G/T of hPOT1 may be a protective factor of gastric cancer.
