Objective To understand the status quo of servant leadership behavior of head nurses in military hospital and its relationship with nurses′ intention to stay, and to make suggestions for maintaining the stability of military hospital nurses. Methods A total of 501 nurses from a military hospital (top three) were surveyed by self-designed general data scale, Head Nurses′Servant Leadership Behavior Scale and Turnover Intention Scale. Results The average score of servant leadership behavior was (80.39 ± 13.79) points, and the correlation coefficient between the head nurse service and the leave intention was-0.255 (P<0.01). Conclusions The servant leadership behavior of the head nurses in a military hospital is at a moderate level and it still can be ameliorated. Training can improve head nurses′capacity of the servant leadership behavior, which can reduce the turnover intention of the nurses in military hospitals.

Objective To discussion of secondary intussusception in children based on ultrasound image,and the diagnosis and the therapeutic value.Methods 23 cases of secondary intussusception in children by the ultrasound image were reviewed and pathogeny analyzed.Results Within this 23 cases of secondary intussusception in children:8 cases in 23 cases were caused by Meckel di-verticulum,4 cases were caused by juvenile polyps,4 cases were caused by intestinal duplication,3 cases were caused by intestinal lymphoma,2 were caused by appendicitis,and 2 cases were caused by intestinal adhesion.And 23 cases of them were all detected by ultrasound at the very first time.22 cases of 23 cases was operated by hydrostatic enema of ultrasonic monitoring treating intussusception successfully,and 1 failed.13 cases were confirmed as secondary intussusception after first enema (Meckel di-verticulum 6 cases,juvenile polyps 3 cases,intestinal duplication 2 cases,intestinal lymphoma 1,and appendicitis 1 cases).9 cases were operated by hydrostatic enema of ultrasonic monitoring treating intussusception again when palindromia happened,which were confirmed as secondary intussusception (Meckel di-verticulum 2 cases,juvenile polyps 1 cases,intestinal duplication 2 cases,intestinal lymphoma 2 cases,appendicitis 1 cases,and intestinal adhesion 1 cases).Conclusion Meckel di-verticulum,juvenile polyps and intestinal duplication are the most common pathologic lead points caused the secondary intussusception in children.The diagnosis of ultrasound is sensitive to children secondary intussusception,and hydrostatic enema of ultrasonic monitoring treating intussusception can be operated under ultrasonic monitoring,which has an even better result than air enema under X-ray.The situation of bowel,which is full of 0.9％ sodium chloride solution,gives operators a good effect of visual to find pathologic lead points.And that really helps to provide valuable image in accordance with clinical surgery therapy of secondary intussusception.

Objective To evaluate the imaging features,pathologic characteristics and diagnostic methods of gastrointestinal stromal tumor(GIST).Methods A retrospective study was performed to analyze the clinical pathological and imaging data of 14 GIST patients diagnosed by surgery and pathology.Results 14 cases of GIST were all solitary.10 cases were located in stomach and 4 cases in small intestine.Tumors were mostly round or oval,and a few of them were irregular lobulated.Immunohistochemistry analysis:12 cases were CDll7 positive and 9 cases were CD34 positive.Conclusion The imaging examination was important to the diagnosis and localization of GIST,but the final diagnosis of GIST depended on histopathological and immunohistochemical examination.

group was also higher than that in the control group, Z=2.39, P<0.05,all which had significant difference, P<0.05.While no significant difference was found in the scores of the Geriatric Depression Scale or the Cornell Scale of Depression Disease between two groups, Z=1.21, P>0.05. Conclusions Reminiscence therapy improves cognitive function, the ability of self-care and social communicate of patients with mild to moderate dementia patients,so that it can improve further patients′quality of life.

Background and purpose:Recently, studies showed that non-steroidal anti-inlfammatory drugs (NSAIDs) could reduce the incidence of cancer. Whether ibuprofen could inhibit the growth of hepatocellular carcinoma cells had not been reported yet. In the current study, we investigated the effects of ibuprofen on hepatoma carcinoma BEL-7402 cells and the relevant mechanisms. Methods: Hepatocellular carcinoma BEL-7402 cells were randomly divided into 7 groups:the control group and the ibuprofen groups (0.1, 0.5, 1.0, 2.0, 3.0 and 4.0 mmol/L). The effect of ibu-profen on BEL-7402 HCC cells was measured by MTT method, the cell cycles were analyzed by flow cytometry (FCM), cell vitality and apoptosis were determined by cell analyzer. PCNA, Cyclin D1, Bcl-2 and COX-2 protein levels were examined by Western blot, and the expressions of prostaglandin E2 (PGE2) were measured by ELISA. Results:After the exposure to ibuprofen, the suppression ratio of BEL-7402 cells was increased (P<0.05). BEL-7402 cell vitality was decreased by degrees significantly (P<0.05), early apoptosis of BEL-7402 cells was increased (P<0.05), and the G0/Gl phase ratio was increased significantly compared with control group (P<0.05). Ibuprofen effectively decreased PCNA, Cyclin D1, Bcl-2 and COX-2 expressions in BEL-7402 cells (P<0.05), and decreased PGE2 protein expression in cell culture supernatants sig-nificantly (P<0.05). Conclusion:Ibuprofen is effective for inhibiting the proliferations, increasing apoptosis and blocking cell cycles of BEL-7402 HCC cells. The anti-tumor mechanisms of ibuprofen may be related with the inhibition of COX-2 and PGE2 expressions.

This study was aimed to analyze the therapeutic effect of Shu-lung post with different stimula-tion intensities on chronic obstructive pulmonary disease (COPD), in order to determine the best stimulus intensity. A multicenter, randomized, controlled clinical trial was designed to take COPD patients at stable stage as study sub-jects. Patients were randomly divided into two groups, which were the foaming group and non-foaming group. The application was given 10 days before the summer dog days, on the 1st, 10th and 20th day within the dog days, and 10 days after the dog days. The results showed that a total of 164 cases were enrolled in the study, with 18 drop-out cases, and 146 cases fitted in the program. There was statistical difference on acute exacerbation frequency
after treatment between the foaming group and non-foaming group (P < 0.05). There were statistical differences on clinical symptoms and signs of total score (P< 0.01) during the 8-month follow-up. It was concluded that Shu-lung post with different stimulation intensities were positively correlation with clinical efficacy.

Objective: To determine the transdermal absorption of phloretin and ligustilide in Fufang phloretin cream.Methods: In vitro percutaneous absorption test using the Franz intelligent transdermal absorption apparatus was adopted, an HPLC method was used to determine the contents of phloretin and ligustilide in the accepting solution at different time points, and then the cumulative release amount and the total penetration amount were calculated to evaluate the percutaneous absorption behavior.Results: Phloretin and ligustilide showed a good linearity within the range of 0.044 2-4.42 μg·ml-1(r=0.999 9) and 0.048 7-4.87 μg·ml-1(r=0.999 9), respectively, the average recovery was 99.85% and 99.92%, and RSD was 0.67% and 0.66% (n=9), respectively.The in vitro permeation behavior of phloretin and ligustilide through the skin of rats fit Higuchi equations(r>0.9), suggesting a good linear correlation between the cumulatine penetration amount (Qn) and (time).Conclusion: Fufang phloretin cream has a good percutaneous permeation property in vitro.
