Objective To construct a geometric skull model by using three-dimensional reconstruction, computer tomography scanning and rapid prototyping technology and evaluate its significance in treatment of complex oral and maxillofacial deformities. Methods A cranial and a goldenhar syndrome patient with complex oral and maxillofacial deformities bone received continuous volumetric scanning of skull and the data acquisition was done by an electron computed tomography, by which reconstruction was performed and the obtained images saved as STL files. Then the data were input into rapid prototyping machine to make three-dimensional geometric model. Direct measurement, designation and surgery simulation could be done on this three-dimensional model. Then the mandibular mirror physical model was manufactured using rapid prototyping according to the normal side. Results A computer-aided model according to CT data could represent the three-dimensional anatomic structures and their relationships precisely. The replica exhibited dimensional errors ranging 0.02 mm to 0.53 mm. Which provided strong basis for accurate understanding of disease status and reasonable surgical plans and helped improve the curative effect of surgery. Conclusion Rapid prototyping can help surgeons in many ways for therapy of the complex oral and maxillofacial deformities.

Objective To evaluate the clinical effects of intra-lamellar orbicularis dissecting micro-traumatic double eyelid surgery for the treatment of adolescent upper eyelid trichiasis. Methods Three cutaneous micro-incisions following intra- and sub-lamellar orbicularis dissections were performed and the deep orbieularis and suborbicularis fat pad between the intended eyelid crease and 1 mm above the eyelid margin were resected. The subcutaneous orbicularis was fixed to the exposed levator aponeurosis at the medial, center and lateral regions. For the quantitative analysis, the entire eyelid margins' eyelashes were equally divided into three sections and the eyelashes lift-up angle (LA), the body curl-up angle (BC) and the end curl-up angle (EC) were compared before and after surgery in each section, respectively. Results One hundred and fourteen eyes of 57 cases were followed up during 24-30 months. Compared to the LA before surgery and 2 years after surgery, it was changed from (26.37±9.67)° to (55.42± 10.03)° in section Ⅰ , and from (22.03±11.64)° to (50.03±10.02)° in section Ⅱ , and from (25.31±8.01)° to (64.05±8.33)° in section Ⅲ. There were no significant changes of BC and EC during following-up. Con-clusions For the adolescent upper eyelid trichiasis, the intra-lamellar orbicularis dissecting micro-trau-matic double eyelid surgery could acquire satisfactory aesthetic appearance and stable eyelashes'position at the same time.

Objective To prepare and characterize the monoclonal antibodies (McAbs) against recombinant adhesion protein 33 (AP33) of Trichomonas vaginalis. Methods The purified recombinant fusion protein AP33 was used as antigen to immunize BALB/c mice. Sp2/0 myeloma cells were fused with the splenocytes from immunized BALB/c mice. After ELISA screening and 4 times of limited dilution, 5 positive hybridoma cell lines were obtained, and the biological properties of the McAbs were identified by Western blotting. Indirect immunofluorescent antibody test (IFAT) was performed and the inhibition effect of McAbs on the cytoadherence of T.richomonas vaginalis to HeLa cell was assayed. Results Western blotting demonstrated that 5 McAbs, designated as 4A2, 4F11, 4F8, 4E7 and 4H11, specifically combined with the recombinant AP33 of T.vaginalis. The McAbs were IgG1 isotypes. Four of them (4F11, 4F8, 4E7 and 4H11) showed parasite recognition by IFAT. Parasite cytoadherence to a monolayer of HeLa cells was inhibited in vitro with a inhibition rate of 50.08%, 65.03%, 50.70% and 49.08% by the 4 McAbs under a concentration of 200, 200, 400 and 200?g/ml, respectively. Conclusions The prepared McAbs against the recombinant AP33 show a protective inhibition on cytoadherence of Trichomonas vaginalis in vitro.
