ObjectiveTo investigate the influence of gender and psychosocial parameters on the quality of life in patients with irritable bowel syndrome(IBS). MethodsOut-patients from Jan to Oct 2008 in the Department of Gastroenterology at the First Affiliated Hospital of Nanjing Medical University were enrolled. Based on Rome teria IBS was diagnosed. Interviewed by a GI physician with questionnaire of demographic data,Zung self-rating anxiety and depression scale(SAS/SDS) and IBS-specific quality of life(IBS-QOL) questionnaire. Results452 patients were diagnosed as IBS according to Rome Ⅲ criteria. IBS was more common in female. In male, anxiety and depression scales were significantly increased( t =7. 191、6. 459 ,P ＜ 0. 01 ) and the scale of IBS-QOL was significantly decreased ( t =9.119, P ＜ 0.01 ) in female IBS patients. In IBS patients, IBS-QOL scales were negatively associated with the anxiety and depression scales(P ＜0. 01 ). ConclusionThese results suggest that there were gender differences in psychological status and quality of life in IBS patients,and difference psychological status based on gender should influence the quality of life of patients with IBS.

The present paper consults the concept of clinical competence, cultivation actuality, examination and assessment system of master of nursing specialist (MNS) at home and aboard based on literature analysis.Currently there is neither unified concept of master nursing specialist clinical competence, nor a unique clinical ability training mode of MNS.This paper mainly expounds the differences of the nursing professional master degree graduate students clinical ability evaluation system at home and abroad in the assessment methods, assessment tools, assessment agencies and assessment index, pointing out that our country should make a unified concept of the clinical competence.We should develop a flexible, diverse clinical competency assessment method, establish specialized evaluation agencies which are independent of the government, and implement 3 level quality monitoring system-graduate school of the university, clinical college graduate school and nursing department of, to ensure the training quality.

The culture conditions of Saccharomyces cerevisiae sp.strain by 1.1 b were optimized for the production of D-(-)-mandelate dehydrogenase which is useful for the asymmetric bioreduction of benzoylformate to form D-(-)-mandelate.The optimum medium(per liter)consistes of 60 g peptone,30 g maltose, 0.5 g MgSO_4,0.01 g ZnSO_4,1.0 g KCl.After optimization of the culture medium,the enzyme production in shake flasks is enhanced from 2.56 to 20.21 U/L.The optimum fermentation conditions were determined as follows:medium volume 100 mL(i.e.,40%for a 250-mL shake flask),pH 6.5,inoculum size 10%,temperature 30℃,and cultivation time 25 h.

Objective To explore the expression of BID protein and the relation ship of cell proliferation with apoptosis at different stages of IgAN.Methods The expression of BID protein、PCNA and FN in renal tissue was detected by immunohistochemistry,TUNEL and light microscopy were used to detect apoptotic cells.Results With the progress of IgAN,the expression of BID protein、PCNA、the number of apoptotic cells and FN increased gradually(P

OBJECTIVE: To explore the clinical application of gastric pharyngeal anastomosis assisted by laparoscope. METHOD: Apply laparoscope in the gastric pharyngeal anastomosis for 4 cases of advanced hypopharyngeal carcinoma and cervical esophageal carcinoma patients. RESULT: Gastric pharyngeal anastomosis assisted by laparoscope were successfully completed in all 4 patients, all patients avoided thoracotomy or laparotomy, one patient occurred pharyngeal fistula, and died six months later. One patient had cervical lymph node metastasis a year and a half later, without treatment again because of economicissue. The remaining two patients were still alive, one patient had survived 3 years and a half after operation, the other had survived 2 years and a half after operation. CONCLUSION Gastric pharyngeal anastomosis assisted by laparoscope is feasible. It can reduce the operation wound, improve the safety of operation and patients' life quality.

OBJECTIVEThis study aims to evaluate the reliability and validity of the Chinese version of the chronic oral mucosal disease questionnaire (COMDQ).

METHODSUsing translation, back-translation, quality evaluation, cross-cultural adaptation, and pre-assessment, a Chinese version of the COMDQ was drafted. A 26-item instrument which comprised of four domains: pain and functional limitation, medications and side effects, social and emotional aspects, and patient support was designed and tested. This questionnaire was given to patients who visited our clinic. After the patients accomplished the questionnaires, we analyzed the collected data to evaluate the reliability and validity of the scale.

RESULTSA total of 130 patients were enrolled in our study. All the COMDQ questionnaires were completely filled out. The Chinese version of the COMDQ showed the following psychometric properties: Cronbach's alpha of 0.914, split-half reliability of 0.809, and correlation of 0.697. Factor analysis of construct validity demonstrated that the 26 items were classified into four domains, and the cumulative proportion was 67.62%. Thus, the scale had certain logical relation between the items in the same domains.

CONCLUSIONThe Chinese version of the COMDQ demonstrate good reliability and validity by rigorous psychometric properties. It can be widely used to test the oral health-related quality of life of patients with oral mucosal diseases.

Objective To investigate the clinical value of serum pepsinogen(PG)Ⅰ,Ⅱ and gastrin-17(G-17)levels in early di-agnosis for atrophic gastritis and gastric cancer.Methods The study was performed on a case-control trial,and 430 subjects were recruited.Each of them underwent endoscopy biopsies before serum tests were performed.These patients were further divided into three groups based on endoscopic and histological findings:160 non-atrophic gastritis group,118 atrophic gastri-tis group and 152 gastric cancer group.Serum samples of PGⅠ,PGⅡ and G-17 were analyzed by enzyme-linked immunosor-bent assay(ELSIA),and calculated the values of PGⅠ/PGⅡratio.Results Compared with the non-atrophic gastritis group, serum PGⅠ and G-1 7 values in atrophic gastritis and serum PGⅠ,PGⅡ,PGⅠ/PGⅡratio and G-1 7 values in gastric cancer group decreased significantly (P<0.05);compared with the atrophic gastritis group,serum PGⅠ and G-17 values in gastric cancer group decreased significantly (P<0.05).By using receiver operating characteristic curves (ROC),the cut-off points of PGⅠ84.706μg/L,PGⅡ 10.873μg/L,PGⅠ/PGⅡ ratio 11.008 and G-178.265 pg/L in atrophic gastritis group,PGⅠ65.145μg/L,PGⅡ 10.089μg/L,PGⅠ/PGⅡ ratio 6.375 and G-17 4.971 pg/L in gastric cancer group.Conclusion Low serum PGⅠ,PGⅡ,PGⅠ/PGⅡ ratio and G-1 7 values are biomarkers of atrophic gastritis and gastric cancer and valuable for the early diagnosis of gastric cancer.

The respiratory control ratio (RCR), the rate of O2 consumption in state 3 and the rate of ATP formation of liver mitochondria succinate respiratory chain were increased 30 min after Sprague-Dawley rats were injected with epinephnne or norepinephrine. The rate of O2 consumption in state 4 was increased or slightly increased. When rats were injected with adrenergic blocking agents, timolol and phenoxybenzamine, 1 h before burn, the activities of succinate respiratory chain were partly inhibited 30 min post-burn. All the results suggest that catecholamines play a main role in the increase of oxidative phosphorylation coupling in the early phase of burn injury.
