ABSTRACT
As one of the common type of ocular injuries,orbital fracture can result in enophthalmos,diplopia and infraorbital nerve injury,which affects the physiological function of eyeball.Repairing surgery for orbital fracture should be treated for reconstructing the orbital anatomical structure in case of severe enophthalmos and diplopia,or infraorbital nerve injury.Meanwhile,it's crucial to identify the suitable surgery approach and implants because of the specificity and complexity of the orbit.What a clinician expected most is the ideal prognosis obtained easily with minimal operation complication.Transconjunctival approach should be applied as one of the standard approaches for repairing surgery of orbital fracture,offering good operative field with less complications.Titanium mesh and resorbable materials are the ideal implants at present,for their high level of stable quality and plasticity.More and more applications of 3D-printed rapid prototyping technique can guide the new directions of individualization and precision of repairing surgery for orbital fracture.
ABSTRACT
OBJECTIVE: To explore the correlation between serum levels of growth differentiation factor-15 (GDF-15) and Thrombolysis in Myocardial Infarction (TIMI) risk scores in patients with unstable angina pectoris (UA). METHODS: The serum levels of GDF-15 in 97 patients with UA and 30 healthy volunteers were measured using enzyme-linked immunosorbent assay (ELISA) and compared between 3 patient groups with different TIMI scores to analyze relationship between serum GDF-15 levels and TIMI risk scores. RESULTS: The serum levels of GDF-15 in UA patients were significantly higher than those in the healthy volunteers (P<0.01). GDF-15 levels also differed significantly between patients with different TIMI scores (P<0.01), and showed a significant positive correlation to TIMI risk scores. CONCLUSION: Serum levels of GDF-15 can be used as an index for evaluating the severity of UA.
