Objective To explore the effect of quality control circle (QCC) in reducing the radiation dose during chest CT scan. Methods QCC was founded, activity themes were selected, activity schedule was planned, the reasons of high radiation dose was analyzed, countermeasures were planned and implemented jointly by circle members, and then per capita radiation dose and image quality before and after improving was compared to confirm the effect of QCC activities. The subjects of chest CT scan before and after improvement in our center were selected, included totally 218 cases, their average age was (47.05 ± 8.58) years, 162 were male, 56 were female, 44 cases had CT scan before improvement, 174 cases after improvement, and the data were analyzed by T-test and Chi-square test. Results The radiation dose per capita has declined from 13.75 mGy to 3.45 mGy, The rate of standard was 102.08%, progress rate was 74.91%. The rate of high-quality image was 92.52%. Compared with per capita radiation dose before and after the activities, the differences were statistically significant(P<0.001). The rate of high-quality image was 93.18% before activities, the percentage remained steady at 92.52% after the activities, there was no statistically significant differences in image quality(P>0.05). Conclusions Application of QCC not only reduced the radiation dose of the client without image quality changes, but also improved thinking and learning capacity, cooperative consciousness of the circle members.

Objective To sum up the measures for nursing the patients with laparoscopic gastrectomy-induced anastomotic leakage treated by open center vacuum aspiration. Method We retrospectively reviewed the histories of 22 patients with laparoscopic gastrectomy-induced anastomotic leakage to look into the nursing measures to look into the management of open vacuum aspiration , observation of the drainage, leakage care, mental care. Results The time for open center vacuum aspiration was between 10 to 17 days, averaged (15.63 ± 3.22)d. The hospital stay was between 13 to 23 days, averaged (17.21 ± 5.47)d. No complications were observed. Conclusions The nursing measures for managing the anastomotic leakage can be effective in improving the effect of peritoneal irrigation. The mental care can be effective for the reduction of patients′pains so as to promote the heal of the leakages.

Objective To investigate the value of differential diagnosis for subcortical ischemic vascular dementia(SIVD)and Alzheimer's disease(AD)with memory and executive screening(MES) scale. Methods Fifty SIVD and 50 AD patients treated in the outpatient and wards of the Department of Neurology,Fuxing Hospital,Capital Medical University from June 2012 to November 2013 were enrolled retrospectively. They were enrolled in either a SIVD group or an AD group. Fifty healthy subjects in Yuetan community of Fuxing hospital were selected as a control group at the same period. The age,sex and education level of the subjects in the 3 groups were matched. The Mini-Mental State Examination( MMSE) and MES were used to measure all subjects and were compared;receiver operating characteristic curves was used to analyze the radio of memory and executive part for SIVD and AD discrimination. Results (1)There was no significant difference in total MMSE score between the SIVD group and the AD group(20. 6 ± 5. 5 vs. 20. 6 ± 3. 3;P>0. 05).(2)There were significant differences in each MES indexes among the patients of the 3 groups(all P>0. 05). The 1,3,4 and 5 scores for the sentence memory in the SIVD group were significantly higher than those of the AD group. There were significant differences(all P<0. 01). The indicators of executive part:the continuous action,instruction and action contradictory stimulation,knock and un-knock with finger scores of the SIVD group were all lower than those of the AD group(5. 1 ± 3. 1 vs. 7. 3 ± 2. 1, 5. 2 ± 3. 0 vs. 7. 7 ± 1. 9,3. 5 ± 4. 4 vs. 6. 2 ± 4. 3;all P<0. 01). The MES-R of the SIVD group was higher than that of the AD group(1. 2 ± 0. 7 vs. 0. 5 ± 0. 2;P>0. 05).(3)When MES-R was≥0. 7,the sensitivity and specificity of differentiating SIVD were 76. 7% and 83. 3%,and the total score of MMSE for differentiating the sensitivity and specificity of SIVD were 40. 0% and 0. 7%. Conclusion The differences of MES reflecting sentence memory and executive part may better distinguish the patients with SIVD and AD.

Objective To analyze the language function impairment differences between the two steps from the form to sound processing and from the sound to meaning processing for pseudo-words reading in Alzheimer' s disease (AD).Methods The pseudo-words reading test consists two parts:pseudo-true words and pseudopseudo words.Each part had 10 words.All of the 20 words were presented randomly.Correct reading presents the processing of from form to sound,and correct judging presents the processing of from sound to meaning.Each correct respond get 1 score,otherwise get 0.Each part had a total score of 20.Results The pseudo-words reading test was performed to 41 mild AD participants with Mini-mental State Examination (MMSE) average scores of (21.06 ±2.86),and 135 normal controls with MMSE average scores of (28.08± 1.52).The two groups were matched in age,gender and education.For all of the mild AD group and normal control group,there was no significant difference between reading score and judging score in either pseudo-true words or pseudo-pseudo words (P＞0.05).Comparing with mild AD group and normal control group,there was no significant difference in reading score in either pseudo-true words or pseudo-pseudo words (P＞0.05).For judging score,there was significant difference in pseudotrue words (P＜0.01) but not in pseudo-pseudo words (P＞0.05).Conclusion Understanding real syllable is impaired in patients with mild AD.

OBJECTIVE:To provide reference for the optimization of automatic system in outpatient pharmacy of the hospital. METHODS:Based on PDCA(Plan,Do,Check and Action)cycle management,the modules for adding and dispensing drugs of the automatic system in the outpatient pharmacy were optimized and the work records and quality indexes before (July-September in 2013) and after (May-July in 2014) the optimization were compared.
