Objective To discuss the influence of grading nursing care by physician-nurse cooperation decision-making on the quality of patient care and disease outcomes,and evaluate the application feasibility of nursing core system in this nursing mode.Methods 379 patients were admitted to departments of orthopedics and endocrinology from two hospital areas of our hospital from January 2011 to January 2012.Patients were divided into two groups according to nursing process.Patients who were given conventional grading nursing were set as the routine group,and patients receiving physician-nurse collaboration grading nursing were set as the collaboration group.The nursing quality and nursing efficiency,and the disease outcome of patients were compared between the two groups.Results The quality of care,the qualified rate of care plan implementation,the coverage rate of health education of patients and the patient satisfaction rate were higher in the collaboration group than those in the routine group.The performing rate of doctor's orders,the awareness rate of patient disease,the average length of hospital stay,compliance of medical orders and re-admission rate of patients with the same or a related disease within three months were significantly different between two groups.The collaboration group improved the matching degree of nursing grade with disease condition,understanding of professional knowledge,recording of nursing records,deficient nursing process,and communication ability of life knowledge,compared with those of the routine group.Conchusions Nursing grading mode by physician-nurse collaboration decision-making can obviously improve the defmition of grading nursing and the general treatment effect of patients,it significantly improved the quality of grading nursing.

Purpose To investigate the influence on shear wave velocity (SWV) by different probe frequency, scanline angle and ROI depth. Materials and Methods The elasticity QA Phantoms was used in the study. First the SWV was measured by curve probe at depths of 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm and 8 cm. The scanline angle changed from 0°from midline, 1°-15°, 16°-30°and 31°-45°. Then the SWV was measured again by using line probe at depths of 1 cm, 2 cm, 3 cm and 4 cm. The measured data were analyzed statistically. Results The SWV showed difference by using the two probes (P<0.05). As depth increased, the measurement by curve probe changed from overestimate to underestimate, while the measurement by line probe always showed underestimate from standard value. When the curve probe was used, the angle and depth affected SWV interactively (F=85.87 and 35.96, P<0.01), and had interactive effects (F=17.63, P<0.01). When the scanline angle was within 15°, the angle had little inlfuence upon the measurement. When the scanline angle was 0 °, the measurement was the closest to the standard value at the depth of 4 cm, and the maximum deviation occurred at the depth of 5 cm. The inlfuence of depth upon measurement had signiifcant difference when the line probe was used (P<0.05). The measurement was the closest to the standard value at the depth of 1 cm, and the maximum deviation occurred at the depth of 4 cm. Conclusion Factors like probe frequency, scanline angle and ROI depth can affect the SWV. When the curve probe is used, the accurate measurement occurs at the depth of 4 cm when the scanline angle is within 15°. When the line probe is used, the accurate measurement occurs at the depth of 1 cm.

Objective To analyze the outcomes and the role of radiotherapy in breast cancer pa-tients with T1-T2 and one to three positive axillary nodes treated with modified radical mastectomy, and to investigate the prognostic factors for loco - regional recurrence in patients without radiotherapy . Methods Three hundred and seventy breast cancer patients with T1-T2 and one to three positive axillary lymph nodes treated with mastectomy and axillary dissection were retrospectively analyzed. Kaplan-Meier method was used to calculate the overall survival (OS) and loco-regional recurrence-free survival (LRFS) rates. The Logrank test was used for the comparison of the survival curves of patients with or without radiotherapy. Univariate analyses of potential prognostic variables for LRFS were performed. Results The 5-year OS and LRFS rates were 85.4% and 91%. Radiotherapy significantly improved the 5-year LRFS rate ( 100% vs. 89.5% ;x2 = 5.17, P=0.023). However, there was no significant difference in overall survival rate between patients with and without radiotherapy. In univariate analyses, T stage, the number of positive axillary nodes, C-erbB-2 and PR status were the significant predictive factors for LRFS. Conclusions For breast cancer pa-tients with T1-T2. and one to three positive axillary nodes, radiotherapy improves the LRFS, but not OS. T stage, the number of positive axillary nodes, C-erbB-2 and PR status are predictive factors for loco-regional recurrence in patients without radiotherapy.
