Objective To investigate the chondrocyte proliferation and extracellular matrix biosynthesis of electrospun PCL scaffolds seeded with rabbit chondrocytes under flow perfusion culture in vitro.Methods Nonwoven PCL microfiber mats were fabricated,and contra-aperture cylindrical glass equipment as a perfusion bioreactor was designed and manufactured on our own.The experiment included peffusion culture group and static culture group.Primary chondrocytes were isolated from the knee joints of two-month-old New Zealand white rabbits and seeded into scaffolds.The scaffold-cell complexes were harvested at 3,7,and 14 days of culture for scanning electron micrograph (SEM) analysis,biochemical assay,real-time PCR and histology analysis.Results Electrospun PCL scaffolds were composed of microfibers with a diameter of 1.67±0.76 μm and pores with a diameter of 17.65±7.11 μm.SEM showed a better cell proliferation with typical morphology of chondrocytes under perfusion culture.At 7 days of culture,DNA content in perfusion culture group was higher than in static culture group.At 3,7 and 14 days of culture,compared with the static culture group,glycosaminoglycan (GAG) content and GAG/DNA ratio in perfusion culture group were higher,and the differences were statistically significant.At 14 days of culture,real-time PCR showed aggrecan and collagen type Ⅱ gene expression and collagen type Ⅱ to collagen type Ⅰ ratio were higher in perfusion culture group than in static culture group; HE and safranin O staining showed a significant cell proliferation,infiltration,as well as extracellular matrix biosynthesis in perfusion culture group.Conclusion Under flow perfusion culture,the electrospun PCL scaffolds seeded with rabbit chondrocytes can enhance chondrocyte proliferation and extracellular matrix biosynthesis,which is a promising method for cartilage tissue engineering.

Objective To investigate the clinical features of Kawasaki disease.Methods A retrospective analysis was performed in 272 children diagnosed as Kawasaki disease from 2002 to 2006.Clinical data,laboratory findings and auxiliary examination results were collected for these patients.Results The male-to-female ratio Was 2.58:1.Onset ages between 1 to 3 years accounted for 59.2%of patients.Of these patients,100%had a fever for more than 5 days,76.1%transient polymorphous exanthema,74.6% bilateral conjunctival hyperemia,47.8%flare and fissure on the oral lip,58.5%strawberry tongue,22.8% firm swelling of hands and feet as well as flushing of palms and soles,3 1.2%subacute desquamation at the junctional site between nail bed and skin,36%cervical lymphadenopathy.Laboratory findings showed a significant increase in the count of peripheral blood leukocytes and pefipheral blood platelets as well as erythrocyte sedimentation rate in 80.5%,87.5%and 96.2% of Patients,respectively.Additionally,81.6%of these patients were positive for C reactive protein and the frequency of coronary aaery involvement was 54.3%.All patients were treated with aspirin,and high-dose intravenous immunoglobulin was given to 258 patients.Fever relieved and the condition was controlled in all patients with an average hospitalization period of 8.9 days.Conclusions Kawasaki disease should be suspected in Patients with exanthematous lesions,fever lasting for more than 5 days and poor response to antibiotic therapy.Peripheral blood platelet count and cardiac ultrasound are of great value in the diagnosis of Kawasaki disease.Aspirin iS the first choice in treating Kawasaki disease,and adjunctive high-dose intravennous immunoglobulin treatment may facilitate the quick control offever.

25%) and low LI groups (positive cell rate ≤25%) of TopoⅡ? and Ki-67. However, in high LI groups, the overall survival rate was lower than those in low LI groups (P=0.002, P=0.004, Log-Rank test), the volume of recurred masses was bigger (P=0.005, P=0.000) and recurrence time was shorter (P=0.000, P=0.000) than those in low LI groups. There existed a significant linear correlation between the expressions of TopoⅡ? and Ki-67 (r=0.935 5, P=0.000). The expressions of TopoⅡ? and Ki-67 were related with pathological category and staging (P0.05). Conclusions Both TopoⅡ? and Ki-67 could be used as specific markers of cell proliferation, but the specificity of TopoⅡ? might be higher than that of Ki-67 in accurately reflecting the cell proliferation. TopoⅡ?, combined with pathological category and staging, may play an important role in prognostic prediction of uterine sarcoma.

Objective To report our usage of a combined flap which is constituted of bilateral hallux nails, skins, bones to reconstruct a finger, and to introduce the method and outcome of this way. Methods Combine two halves of halluxes harvested from both feet to reform a fabricated finger and then transplant it to the finger stump to reconstruct the defect part of the finger. Plantar flaps or some other flaps near the donor sites were transposed to cover them. From June 2003 to June 2009, a total of 20 fingers (20 cases) which had defect degrees range from I to Ⅲunderwent reconstruction surgeries in this way. Results All the 20 fingers transplanted survived completely. Follow-ups 1 to 5 years after each surgery: all the fabricated fingers had very realistic configurations. The MP joints of the reconstructed thrumbs got to the normal range of motion, and the other reconstructed fingers' total ROM were 203 degree on average. All the reconstructed fingers had the sensation function above S3,and their two-point discriminations ranged from 6mm to 10mm. Both halluxes of each case were conserved major parts of nails and had nice, symmetric appearances. All the flaps for the donor halluxes survived completely, and none of the cases showed pains, ulcers or abrasions of their feet. All the cases showed normal gaits during follow-ups. Conclusion The combined flap by bilateral hallux nails, skins, bones is an ideal alteration for finger defect reconstruction for the important advantages of realistic configuration as well as minor destructions to donor sites.
