Objective To evaluate the clinical efficacy of China-made expanded polytetrafluoroethylene (ePTFE) in the treatment of facial defects and hollow deformities on the face. Methods Facial augmentation was performed in different sites as the forehead, temple, nose, chin, nosal base and maxilla, respectively, to correct the facial defects and hollow deformities, by using either China-made ePTFE (Experimental Group) or imported ePTFE (Control Group). Postoperative parameters between the two groups were compared. Results The Experimental Group included 16 patients (18 sites), in whom the postoperative follow-up was conducted for 6~9 months. In this group, a secondary infection (in the nose) occurred in 1 patient because the implant was placed too superficially and too close proximity to the incision, and the implant was removed out. Delayed healing of the incision (in the chin) with uncovered implant was found in 1 patient, who was cured by the change of dressing. In the rest of the patients, no obvious allergic, inflammatory or rejection reaction was seen and a good cosmetic result was achieved. The satisfactory rate of this group was 94.4%(17/18). The Control Group included 10 patients (20 sites). The implant was found bared and then removed in 1 patient (in the nose). The satisfactory rate of this group was 91.7%(11/12). There were no statistical differences between the two groups in the wound healing ( ? 2 =1 109, P =0 574), the adverse reaction ( P =1 000), and the clinical efficacy ( P =1 000). Conclusions China-made ePTFE gives histocompatibility as good as imported one. It is suitable for filling the soft tissue and can be used as a safe and economical alternative.

There was significant difference between the two groups of patients with the image noise and enhance the effect (t=-4.736, 11.927;P<0.05); Group B of coronary artery stenoses (more than 50%) and severe stenosis (more than 75%) sensitivity, specially degree and coincidence rate compared with the results of CCA showed no significant difference. Kappa consistency analysis showed that the two consistency is good(kappa=1.320,P<0.001).Conclusion: In the premise of ensuring the image quality with low tube voltage, low concentration of contrast agent volume coronary CTA examination had safety and reliability of inspection.

Objective To explore the role of health management in the treatment of rheumatoid arthritis combined with osteoporosis.Methods A total of 140 women with postmenopausal osteoporosis and rheumatoid arthritis were enrolled in this 12-month randomized controlled study and randomly assigned to receive drug therapy ( group A,n =70 ) or drug therapy + health management ( group B,n =70 ).Bone mineral density (BMD) of the forearm,lumbar spine and hip was measured by using dual-X-ray absorptiometry at baseline and 12 months after the intervention.The rates of fractures were calculated at 12months.Results BMD of the forearm,lumbar spine and hip of both groups were significantly increased at 12 months (group A:0.50 ± 0.13,0.78 ± 0.15 and 0.68 ± 0.14,respectively,all P ＜ 0.05; group B:0.54± 0.14,0.80 ± 0.12 and 0.73 ± 0.15,respectively,all P ＜ 0.05 ).The elevation of BMD and therapy compliance of group B were significantly higher than those of group A ( P ＜ 0.05 ),while the rate of fracture was relatively lower.Conclusions Health management can significantly improve patient compliance and medication efficacy.

Objective To investigate the different procedure effects in patients with modified sub-pectoral and subglandular breast augmentation. Methods Patients with modified subpectoral breast aug-mentation (10 cases) and subglandular breast augmentation (10 cases) were randomly selected, and satis-factory surveys to the procedures were conducted in the two groups of patients, including breast touch-feeling, dynamic change, as well as self-feeling and spouse-feeling. Results By the comparison of sub-glandular with subpectoral breast augmentation, touch-feeling was excellent in the former group, with breast spreading out to bilateral side in horizontal position. The breasts had different changes with differ-ent posture and natural movement. Spouse was more satisfactory to the former than the latter group. Conclusion Subglandular breast augmentation has natural shape, dynamic changes and fidelity of the re-al, especially in horizontal position, which is more conformable to the standards of patients and their spouse, and better than subpectoral breast augmentation.
