In order to fully understand the anxiety level of the patients who will have ultrasound-guided puncture biopsy, and the survey results will guide the future clinical care to reduce the anxiety score of the patients, and to im-prove the satisfaction of them, which reflects the quality of care, we used Zung Self-rating Anxiety Scale (SAS) to investigate outpatients who will have ultrasound-guided puncture biopsy in a upper first-class hospital by convenience sampling way. The results showed that the SAS standard score of the patients was higher than the Chinese normal population's, and there is significant difference between the patients and the normal population's score (t = 47.12, P < 0.001). So for reducing the patients' anxiety level we should give health education and care intervention to the patients before the operation. This reflects the Patient-centered Culture and Excellent-quality Care in China.

OBJECTIVE: To investigate the effect of the integration pattern of hospital-community on the grade-based management for hypertension in elders.
 METHODS: We randomly chosen 218 (male, n=121; female, n=97) primary senile hypertension patients from a Community Health Service Center of District in Changsha City, from June, 2013 to December, 2013. Based on the risky factors, the subjects were divided into three groups and every group received grade-based management on blood pressure with a integration pattern of hospital-community for six months. According to the HILL-BONE high blood pressure compliance scale and the self- designed blood pressure monitoring form, we assessed the effect of compliance and blood pressure control on senile hypertension patient. 
 RESULTS: Hypertension treatment rate for the elders ranged from 22.9% to 88.1% (P<0.01). The levels of blood pressure of the subjects were significantly decreased compared with baseline. The level of diastolic blood pressure in the low, average, high and very high-risk group was decreased by 17, 20 and 23 mmHg, respectively (P<0.01). The level of systolic blood in the low, average, high and very high-risk group was decreased by 6, 5 and 7 mmHg, respectively (P<0.01). The compliance rate of HILL-BONE hypertension rose from 54.5% to 87.4% (P<0.01).
 CONCLUSION The integration pattern of hospital-community with the grade-based management for hypertension significantly improved the senile hypertension control rate and compliance of drug treatment. The rational for drug usage rate rose obviously. The integration pattern of hospital-community with the grade-based management for elders deserves to spread.

OBJECTIVE: To understand the influential factors for depression in patients with facial acne vulgaris and to provide scientific evidence for a comprehensive and systematic treatment for acne vulgaris.
 METHODS: A total of 287 outpatients with facial acne vulgaris, who visited the dermatology of the Third Xiangya Hospital, were surveyed by Beck Depression Inventory (BDI). The data was collected by Epidata software (version 3.1) and processed by SPSS software package (version 18.0). The influential factors for the depression of outpatients with facial acne vulgaris were analyzed by multinomial logistic regression.
 RESULTS: A total of 181 patients with facial acne vulgaris showed various degrees of depression (BDI score≥5) and the rate was 63.1%. The symptoms for depression included sad and pessimistic attitude as well as the decreased attention to others (social withdrawal). The influential factors for mild, moderate or severe depression were gender, the degree and the course of acne. Female patients were more likely to suffer mild, moderate or severe depression (OR=3.62, 2.63, respectively); the risk of depression in acne patients was increased with the increase in degree of the severity (OR=2.31, 4.51, respectively); the patients with the acne course more than a year were more likely to show mild depression than those with a course less than a year (OR=4.30, 7.44, respectively). The patients with acne course more than 3 years were more likely to show moderate or severe depression compared to those with a course less than a year (OR=3.60).
 CONCLUSION Most of facial acne patients show a different degree of depression. The acne course is longer in female patients. The more severe the acne vulgaris is, the more suffering of the depression is. Psychological care should be considered to improve the treatment and quality of life.
