Objective To study the gene expression of Wnt signal transduction pathway in experimental liver fibrosis and to investigate its role in liver fibrosis. Methods Liver fibrosis model was induced with carbon tetrachloride in 8 SD rats. Another 8 healthy rats were served as control. The gene expression in liver tissues of models and controls were examined using real time PCR array. The differential gene expression was identified as either up- or down-regulated 2-fold. The expressions of smooth muscle actin (SMA), Wnt4, Frizzled2 and β-catenin in the tissues were examined by immunohistochemistry and Western blot. Results The examination confirmed that 36 genes were differentially expressed, including 25 genes up-regulated and 11 genes down-regulated. Compared with the controls, the expressions of Wnt4, Wnt5 a and W nt11 were up-regulated more than 13.9-, 16.5-and 2.17-fold respectively, while the expressions of Wntl and Wnt3 were down-regulated more than 2.32- and 2.15-fold respectively in fibrotic liver. Immunohistochemistry and Western blot showed that the expressions of SMA, Wnt4 and Frizzled2 in fibrotic liver were remarkably higher than those in normal controls. While the level of phosphorylated β-catenin was decreased. Conclusion Both canonical and noncanonical Wnt signal transduction pathway may involve in the mechanism of liver fibrogenesis.

Abstract?AlM:To evaluate the accuracy and practicability of three - dimensionally preformed Arbeitsgemeinschaft Osteosynthese AO titanium mesh plates for orbital fractures.?METHODS:Forty-seven patients with isolated blow-out orbital fractures were included in this study. Fracture locations were as follows: floor/medial wall ( n = 26, 55%), medial wall ( n = 12, 26%), and floor ( n = 9, 19%) . The floor fractures were exposed by a standard transconjunctival approach, whereas a combined transcaruncular transconjunctival approach was used in patients with medial wall fractures with temporary dissection of inferior oblique muscle. A three -dimensionally preformed AO titanium mesh plate was selected according to the size of the defect previously measured on the preoperative computed tomographic scan examination and fixed at the inferior orbital rim with 2 screws. The accuracy of plate positioning of the reconstructed orbit was assessed on the postoperative computed tomography ( CT) scan. The practicability of clinical use of AO three - dimensionally preformed titanium mesh plates was assessed on the preoperative and postoperative clinical data.?RESULTS: Postoperative orbital CT scan showed an anatomic three- dimensional placement of the orbital mesh plates in all of the patients. All patients had a successful treatment outcome without clinical complications. 40 patients ( 87%) had a successful enophthalmos correction. 25 patients ( 86%) had a successful recovery from diplopia.?CONCLUSlON: Three- dimensionally preformed AO titanium mesh plates for orbital fracture reconstruction results in an accurate anatomic restoration of the bony orbital contour with a high rate of success to correctenophthalmos and diplopia.

Objective To measure the tensile strength of the normal medial patellofemoral ligament (MPFL), and evaluate the biomechanics of different fixation methods of the hamstring tendon graft on the patella.
Methods Eight fresh cadaver knees were prepared by isolating the patella, leaving only the MPFL as its attachment to the medial condyle of femur. The MPFL was reconstructed by three different methods:four-suture fixation, anchors-single suture fixation, and anchors-double suture fixation. The tensile strength and the elongation of the normal MPFL and the tendon grafts were measured.
Results The tensile strength of the four-suture fixation group (234.86±49.02 N) was stronger than that of the normal MPFL (146.91±25.30 N, P=0.0014) and the anchors-single suture group (159.17±49.07 N, P=0.0077), while weaker than that of the anchors-double suture group (314.74±78.46 N, P=0.0052)
Conclusions With regard to the tensile strength, the four-suture fixation method is reliable for clinical use. Compared with the anchor-suture method, the four-suture fixation method which has no specific implants is more economical, convenient and efficient.
