BACKGROUND:Hip’s anatomy structure is complex, and the traditional two-dimensional imaging, such as X-ray film or CT scan, is susceptible to image overlap and other soft tissue. As a result, there are some limitations in the diagnosis of hip disease. The digital model is built based on reverse engineering and rapid prototyping. It is comprehensive, intuitive and accurate of the stereo configuration of the hip and the spatial relations of other parts’ anatomical structures. This study has a broad application prospect. OBJECTIVE:To reconstruct the personalized three-dimensional entity model of the hip bone with computer aided technology. METHODS: The human hips were scanned with a portable three-dimensional laser scanner, and then the point cloud data of the hips were gotten. The point cloud was processed and the three-dimensional model reconstruction was carried out by using the engineering software Geomagic and the computer aided software CimatronE. Three-dimensional print of hip was completed and the model was gotten, which was consistent with the geometry of hip bone, through the rapid prototyping machine. RESULTS AND CONCLUSION:A model with good geometric similarity and biomechanical characteristics was built by digital modeling method based on reverse engineering and rapid prototyping. This way of digital modeling provided the basis for digital manufacturing of artificial hip, virtual assembly, stress analysis and surgical simulation.

Objective To investigate the efficacy and safety of low-dose prednisone combined with methotrexate (MTX) and hydroxychloroquine (HCQ) in the treatment of rheumatoid arthritis (RA).Methods In this 12-week study,150 patients with active rheumatoid arthritis were randomly divided into two groups:prednisone group (70 cases who were received prednisone 5 ～ 10 mg/d + MTX 10 mg/w +HCQ 0.2 g/d) and control group (80 cases who were treated by Meloxicam 7.5 mg/d + MTX 10 mg/w +Leflunomide (LEF) 20 mg/d).The primary end-points were tender and swollen joint counts,visual analogue scales (VAS),and global physician and patients assessments of disease.The secondary end-points were morning stiffness time,C-reactive protein,erythrocyte sedimentation rate,the Health Assessment Questionnaire (HAQ),DAS28 and ACR20,ACR50.Results After 12 weeks,in terms of primary endpoints,tender and swollen joint counts,VAS and global physician assessments in the prednisone group were improved significantly [(4.5 ± 2.5),(3.2 ± 3.36),(21 ± 15),(24.2 ± 16.4),(20.2 ± 10.4) vs (6.4 ±5.84),(6.6±5.5),(46±14),(37.9±19.7),(34.1±12.4),P ＜0.05orP ＜0.01].In terms of secondary end-points,the prednisone group produced higher response rates [HAQ score (0.93 ± 0.52),CRP(10.2 ± 5.8) mg/L,ESR(30 ± 14) mm/h,morning stiffness time (32.0 ± 32.3) min,DAS 28 score (3.1±0.9) vs (1.22 ±0.81),(16.3±10.1)mg/L,(33±29)mm/h,(54.7±45.4)min,(4.9±1.9),P ＜0.05 orP ＜0.01].The incidence of adverse events was similar between two groups (43％ vs 49％,P ＞ 0.05).Conclusions Low-dose prednisone combined with MTX and HCQ produced rapid and relevant improvements in RA signs and symptoms.
