1.Current Development of Breast-Specific Gamma Imaging (BSGI) Technique.
Chinese Journal of Medical Instrumentation 2015;39(2):108-112
Breast-Specific Gamma Imaging (BSGI) is an improved and optimizing nuclear medicine breast imaging technique on the basis of traditional gamma camera. It uses a high resolution, small field-of-view scintilla detector. The detector is designed with 3 073 individual detector crystals and 48 position-sensitive photomultiplier tubes. The FOV of detector is 15 cm x 20 cm, and optimal system resolution for breast imaging is 3 mm, can detect the diameter of only 2-3 mm small lesions. BSGI has better sensitivity in detecting subcentimetre or nonpalpable breast cancer. The sensitivity for the diagnosis of breast cancer is high, not influenced by the density of the breast tissue, implants, architectural distortion-or scars from prior surgery or radiation. So it is called a high resolution, small field-of-view breast-specific gamma camera.

Chinese Journal of Practical Nursing 2009;25(3):17-19
Objective To investigate the influence of nursing intervention on hormone treatment compliance of patients with nephrotic syndrome. Methods 130 patients with nephrotic syndrome who received hormone treatment were randomly divided into the experimental group and the control group ac-cording to the time of admission. The control group were treated with conventional nursing, and the ex-perimental group was given whole-process health education besides conventional nursing.Using question-naires, the level of relevant knowledge and medication compliance were compared between the two groups .The results underwent χ2 and t test. Results The treatment compliance was not significant be-fore nursing intervention, while after nursing intervention, the treatment compliance of the experimental group was better than that of the control group. The score of relevant knowledge about nephrotic syn-drome of the experimental group was higher than that of the control group Conclusions Active nurs-ing intervention can improve the health knowledge level of patients and improve the treatment compli-ance of hormone therapy.

Objective To investigate the mental health and its correlated factors for senile dementia caregivers in nursing homes in Shenyang. Methods Questionnaire survey was conducted among 174 senile dementia caregivers recruited from the Nursing Home of Shenyang and Shenyang Social Welfare Institute by using Symptom Check-List-90 (SCL-90), Social Support Rating Scale (SSRS) and self-designed general information questionnaire and to analyze the scores of self rating scale of nursing staff, the total score of social support scale, and the factors affecting the mental health status of nursing staff. Results The SCL-90 scores of senile dementia caregivers with education levels from illiteracy, primary school or junior high school, high school or secondary school, college or above were 130.50 ± 10.11, 132.70±12.55, 135.06±9.15, 129.24±8.83, the difference was statistically significant (F=15.05, P<0.01). The SCL-90 scores of senile dementia caregivers with poor, general and good perceived health status were 133.40±10.52, 132.60±11.32, 128.00 ±10.02, the differences were statistically significant (F=9.07, P<0.01). The SCL-90 scores of family monthly income of 1001 to 3000 yuan, 3001 to 5000 yuan and more than 5001 yuan were 132.90 ± 10.39, 132.80 ± 11.52, 131.50 ± 8.20, the difference was statistically significant (F=12.11, P<0.01). The multivariate linear regression analysis showed that the regression coefficient of perceived health status was-0.168 (t=2.880, P<0.01), monthly family income was-0.145 (t=-2.512, P<0.05), SSRS was 0.121 (t=2.112, P<0.05). Conclusions Mental health status of senile dementia caregivers in Shenyang is poor. The health sector should take some measures to improve the degree of social support, nursing staff wages and to ensure their health in order to promote physical and mental health of nursing staff and the nursing level so as to improve the quality of life of the senile dementia elderly.
