Objective To investigate clinical effect of reattribution-cognitive-pharmacy model (RCPM) in the treatment for irritable bowel syndrome(IBS). Methods 125 subjects with diarrhea predominant irritable bowel syndrome (IBS-D) were divided into two groups randomly. 62 patients in group A were treated with 10 ～ 20 mg of paroxetine without any other medication or psychological interview and 63 patients in group B received RCPM with interviewing once a week for 6 sessions and took 10 ～ 20 mg of paroxetine in the same way as group A after a week. The effect was evaluated at the end of 4 weeks and 12 weeks by a questionnaire. Results At the end of 4 weeks,29 patients in group A reported a reduction in abdominal pain,and 28 reported a reduction in stool frequency ,and 12 patients stopped taking paroxetine because of worrying about those side effect . In group B 48 reported a reduction in abdominal pain ,and 42 reported a reduction in stool frequency ,and 3 patients stopped taking paroxetine. At the end of 12 weeks,36 patients in group A reported a reduction in abdominal pain ,and 30 reported a reduction in stool frequency,and 14 patients stopped taking paroxetine because of worry about those side effect. In group B,54 cases reported a reduction in abdominal pain,and 45 reported a reduction in stool frequency,and 5 patients stopped taking paroxetine because of no obvious improvement. Conclusion RCPM can alleviate the abdominal pain and bowl movement frequency of IBS-D,and it seems better than paroxetine treatment alone. RCPM can improve compliance of paroxetine in patients with IBS-D.

Objective To explore the psychological availability of the full-time candidates for master degree of nursing during the clinical work. Methods A phenomenological approach was adopted in this study. About 11 full-time candidates for master's degree of nursing took part in the semi-structured and in-depth interviews and the acquired data were analysed. Results About 4 themes promoting psychological availability were identified: strong research knowledge and skills, career development confidence, perception of attention from leaders and more satisfactory salary. The four themes hindering psychological availability were:clinical work tasks, lower level of expertise, lack of social support and lower perception of self benefit. Conclusions The full-time candidates for master's degree hold active perception and much expectation about their clinical work but meanwhile they feel passive and disappointed. Nursing administrators should develop distinguishing and definite clinical personnel training and continuing education programs for them, offer them an access to learning chances and emotional support in order to improve the psychological availability and stabilize the nursing team.

Objective To explore the clinical,endoscopic,pathologic and prognostic characteristics of primary gastric lymphoma (PGL) and to improve the level of diagnosis and treatment.Methods Sixtythree patients who were confirmed as PGL with operation and endoscopic biopsy pathology during January 2001 to December 2010 were retrospectively analyzed with respects of clinical,endoscopic and pathologic features.Survival analysis and prognosis were evaluated by kaplan-Meier and Cox proportional hazard model,respectively.Results In 63 PGL patients,the numbers of male and female were 40 and 23,respectively,and the average age was (59.8±13.3)years.The major symptoms were abdominal pain,abdominal distension,and gastrointestinal hemorrhage,accounting for 47.6 ％ (30/63),17.5 ％ (11/63),and 17.5 ％ (11/63),respectively.There were 39 (61.9 ％) PGL patients with endoscopic performance for ulcers,34 (54.0 ％) cases involved the gastric stomach antrum.The most immunohistochemistry analyses were diffuse large B-cell lymphoma (DLBCL) (71.4 ％,45/63),followed by mucosa-associated lymphoid tissue (MALT) lymphoma (22.2％,14/63).The frequency of Helicobacter pylori (H.pylori) positivity was lower in patients with DLBCL than that in patients with MALT lymphoma (37.8％(17/45) vs 10/14,x2 =4.872,P=0.027).The accumulate survival rates of one,three and five years were 74.6％,63.5％,55.6％,respectively,and the average survival time was (41.5±3.0) months (95％ confidence interval (CI) 35.7 to 47.4 months) in PGL patients.There was no difference in the average survival time between DLBCL patients treated with surgery combined chemotherapy and those with surgery or chemotherapy alone (38.33±5.21) months vs (50.17±8.98) months vs (41.39±4.40) months,P＞0.05).The patients diagnosed as DLBCL with H.pylori positive had longer average survival time than those with H.pylori negative ((51.90±4.30) months vs (33.30±4.50) months,t=-4.004,P＜0.01).Conclusions Male patients with PGL are slightly more than female.Abdominal pain is the most frequent symptom.Ulcerative lesions are the most common endoscopic demonstrations mostly at stomach sinus.DLBCL is the most pathologic characteristic.There is no significant difference in the survival rate between patients treated with surgery combined with chemotherapy and those treated with surgery or chemotherapy alone.
