Objective To compare the results between double-threaded compression screws and cannulated lag screws for Garden type Ⅰ/Ⅱ femoral neck fractures.Methods Data of 56 patients with Garden type Ⅰ/Ⅱ femoral neck fractures who were treated with internal fixation from July 2012 to March 2016 were retrospectively analyzed.According to different fixation,the patients were divided into two groups:double-threaded screws group (group A) including 27 cases (7 males and 20 females,with an average age of 55.5±10.0 years,14 cases Garden type Ⅰ and 13 cases Garden type Ⅱ,the proportion of osteoporosis 10/27;And lag screws group (group B) including 29 cases (8 males and 21 females,with an average age of 57.2±9.5 years,11 cases Garden type Ⅰ and 18 cases Garden type Ⅱ,the proportion of osteoporosis 15/29.The 2 groups were compared with respect to bony fusion time,nonunion,avascular necrosis of femoral head,shortening of femoral neck and Harris Hip Score.Results The average follow-up time was 20.3±8.7 m in Group A and 24.5±7.9 m in Group B.The average bony fusion time was 5.3±0.6 m in Group A and 4.1±0.8 m in Group B,and there was significant difference between the groups (t=5.758,P=0.00).1 avascular necrosis of femoral head was found in both groups.In group A,there were 3 cases of bone nonunion (11.1％,3/27).There were one bone nonunion (3.4％,1/29) case in group B,with no statistically significant difference between groups.Shortening of femoral neck occurred in both groups,the average horizontal shortening was 5.8±2.9 mm and vertical shortening 7.0±3.4 mm in Group A,which were lower than group B (8.2±3.1 mm,9.4±3.6 mm),and the differences showed statistically significant (t=-2.94,P=0.005;t=-2.48,P=0.016).In group A,the average Harris Hip score was 88.2±8.3,while that in group B was 89.9±7.2.There was no statistically significant difference between two groups.Conclusion It seems to us that in the treatment of Garden type Ⅰ/Ⅱ femoral neck fractures,doublethreaded compression screws fixation could reduce femoral neck shortening,but there is no difference on functional outcome compared to cannulated lag screws fixation.On the contrary,double-threaded compression screws fixation is not conducive to fracture healing due to lack of sliding compression.

[ ABSTRACT] AIM:In order to observe the myocardial differentiation capacity of the dedifferentiated fat ( DFAT) cells treated with vitamin C in vitro.METHODS: DFAT cells were dedifferentiated from the mature rat adipocytes with ceiling adherent culture.The DFAT cells of passage 3 were used in the study.Vitamin C and/or neonatal rat heart tissue lysate were added into the culture medium to induce myocardial differentiation for 3 weeks.The cell morphology was ob-served under microscope.The myocardial-specific markers, such as cTnT, GATA-4 and NKx2.5, were examined by the methods of immunofluorescence, PCR and Western blot.RESULTS:Mature rat adipocytes dedifferentiated into fibroblast-like DFAT cells after ceiling adherent culture.The DFAT cells spontaneously differentiated into cardiomyocyte-like cells under normal culture condition with a low incidence.After treated with neonatal rat heart cell lysate, the DFAT cells be-came cardiomyocyte-like cells that had bigger size, longer shape and myotubule-structure.The expression of cTnT, GATA-4 and NKx2.5 was remarkably increased at both mRNA and protein levels as compared with the normal cultured DFAT cells.The expression of cTnT, GATA-4 and NKx2.5 was further increased in DFAT cells after treating with vitamin C.No spontaneous beating cell was observed.CONCLUSION:Vitamin C enhances the differentiation of DFAT cells into cardio-myocyte-like cells.

0.05).Some waves(N2,P3,N3) were even absent in children with TS and mental retardation.Statistical analysis indicated that the differences were significant(all P0.05).Conclusion The functional deficit in TS was localized prominently in cerebral cortex and subcortex,and the changes of SEP were almost same marked on both sides.

Objective To analyze the incidence, clinical feature and late complications, and treatment for diabetes ketoacidosis (DKA) in children with type 1 diabetes mellitus.Methods Ninty children with type 1 diabetes mellitus within 10 years were retrospectively reviewed.The onset situation,clinical feature and long-term complication,and treatment of DKA were analized.Results High morbidity was found in 10 to 16 years old children.DKA was often caused by infection; late complications of diabetes mellitus was resulted from interrupted injection of insulin.Conclusions Emergency treatment for DKA may involve the injection of small dose insulin,correction of the disorder of water and electrolysis and regulation of acid-base.The education of patients and parents about diabetes mellitus and long-term injection of insulin are of importance in preventing the complications.
