FFDM differential diagnosis of mastitis,benign hyperplasia and breast cancer / 实用肿瘤学杂志

Objective The aim of this study was to investigate FFDM differential diagnosis between breast mastitis,benign hyperplasia and breast cancer. Methods Fifty-nine cases of non-puerperal breast mastitis,sixty-eight cases of benign hyperpla-sia and two hundred and forty cases with non-mass type breast cancer were analyzed retrospectively,which were verified by surgery and pathology by contrast with FFDM signs,pathological types,grouped and statistics processed. The observation indexes of lamellar shadow included shape,density and edge. The observation indexes of linear shadow included direction,form and diameter. Results The FFDM signs in three groups of breast diseases were statistically significant(P<0. 05):the form of linear shadow,accompanied by calcifications,the shape of lamellar shadow,the direction of linear shadow,the distribution of lesion,the sharp angle of shadow edge. χ2 segmentation show that there were significant differences between three groups(P<0. 0125):the shape of lamellar shadow,the direc-tion of linear shadow. Conclusion There have some values for the diagnosis of breast cancer by rigid form and radial distribution of linear shadow,rigid shape and segmental distribution of lamellar shadow,the polymorphic calcifications and the sharp angle sign.

Research on Limb Rehabilitation Equipment Based on Computer Aided Tri-Dimensional Interface Application / 中国康复理论与实践

Objective To simulate and evaluate the upper and lower limbs posture on rehabilitation devices training with the Computer Aided Tri-Dimensional Interface Application (CATIA) man-machine analysis module. Methods The human body sizes were determined as the 95th percentile Chinese men. Based on the ergonomics analysis of CATIA, three-dimensional human body was constructed in the upper and lower limbs rehabilitation equipment. Virtual human relationship was established. The attitude of the upper and lower limbs in rehabilita-tion equipment was simulated and evaluated. Results The human limbs model moved in the normal range and the scores were more than 90 which meant comfortable. The forces of various parts of the body was under the stress limit, as well as the force moment. The arm tension was 3-5 points with the rapid upper limb assessment, which meant the rehabilitation equipment was acceptable. Conclusion Rehabilitation robot may be optimized through the model of the human upper extremity stretch domain analysis, body posture assessment, rapid upper limb assessment and biomechanical analysis under CATIA.

Application of brainstem auditory evoked potentials in evaluation of children with spastic cerebral palsy / 中华物理医学与康复杂志

Objective To explore the value of brainstem auditory evoked potentials (BAEP) in the evaluation of spastic cerebral palsy (CP). Methods Forty five cases of CP children were recruited and divided, according to the diagnosis standards, into three groups: diplegia, hemiplegia and tetraplegia groups. Twenty three healthy children served as control. BAEP was recorded from all the subjects and comparisons were done among the various groups. Results The abnormality rate of BAEP in the hemiplegia and tetraplegia groups was significantly higher than that in the diplegia group ( P

Dorsal augmenting aesthetic rhinoplasty using autogenous septal cartilage / 中华医学美学美容杂志

Objective To introduce a method of dorsal augmentation rhinoplasty using autogenous septal cartilage. Methods Autogenous septal cartilage was obtained through a standard septoplasty approach. Graft was cut into single oval, or divided into two or three parts, then the cartilage was sutured by means of a mattress suture; or graft was made into an inverted V frame, depending on size and shape of dorsal depression, and finally graft was inserted for augmentation of dorsum. Results Since May 1989 to Dec. 2001, this technique was performed in 43 patients, 6 men and 37 women, with a range of 17-35 years and a mean age of 24 years. Follow-up ranged from 6 months to 5 years. The authors asserted the sustained satisfactory outcomes. Conclusion Autogenous septal graft is technically simple and relatively free of complication. Long-term evaluations show no absorption of grafts and preservation of desired shape.

Recombinative repair for old malunion of the fracture of nasal bone / 中华医学美学美容杂志

Objective To introduce a new method of recombinative repair for the old malunion of the fracture of nasal bone. Methods Since 1996.5 to 2001.12, this technique was performed in 28 patients, 23 men and 5 women, with a range of 18～45 years, a mean age of 29 years. The nasal skin was protected with a rubber pad, and malformed nasal bones were beat out with a small hammer, so as to create a new refracture, then manual reduction was performed with finger and the septal periosted elevator. Results Follow-up ranged from 3 months to 5 years. Of all the patients, 23 cases were cured, 5 cases improved, and the overall effective rate was 100 %. Most of them were satisfied with the successful operation. Conclusion The operative procedure of recombinative repair is technically simple and easy, and the patients suffer little. It is an update and efficacious therapeutic method.

Septal cartilage augmentation for hump nose plasty / 中华医学美学美容杂志

Objective To introduce a new method of septal cartilage augmentation for hump nose plasty. Methods The section of septal cartilage was collected and divided into two or three parts. The grafts were sutured by means of a mattress suture, and placed over the dorsum of superior and inferior hump. The dorsum became flat and straight immediately afterward. Results After a short term and long term follow up, 30 patients who underwent this operation were satisfied the operative results. Conclusion Septal cartilage augmentation for hump nose plasty is an efficient new method.
