The purpose of this study is to assess the effects of anti-inflammatory on activation of nuclear factor-kappaB and mRNA and protein expression of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1) in intestinal mucosal biopsy specimens from patients with ulcerative colitis (UC). A total of 27 cases with UC were investigated. 15 cases received sulfasalazine (SASP) treatment or SASP and glucocorticoid treatment, 12 cases did not receive any medication related with UC. Normal mucosa from 9 colon cancer cases served as control. Ten pieces of intestinal mucosal biopsy specimens were obtained from each patient. The mRNA expression of ICAM-1 and VCAM-1 were determined by reversal transcription-polymerase chain reaction (RT-PCR). The protein levels of ICAM-1 and VCAM-1 were measured by enzyme linked immunosorbent assay (ELISA). NF-kappaB DNA binding activity was evaluated by electrophoretic mobility shift assay (EMSA). The results showed that NF-kappaB DNA binding activity, mRNA and protein expression of ICAM-1 and VCAM-1 were increased significantly in patients with UC, compared with normal control (P<0.05). Glucocorticoids and SASP markedly inhibited NF-kappaB activation and significantly decreased mRNA and protein expression of ICAM-1 and VCAM-1 (P<0.05). Adhesion molecules (ICAM-1 and VCAM-1) gene activation had significant positive correlation with the NF-kappaB DNA binding activity (r=0.8652 P<0.05, r=0.7902, P<0.05, respectively). We concluded that NF-kappaB is a major and essential factor in regulating the expression of adhesion molecules, it plays an important role in the pathogenesis of UC. SASP and glucocorticoids ameliorate UC via inhibition of NF-kappaB activation and reduction of adhesion molecules expression.

To investigate if nuclear factor-kappa B (NF-kappa B) p65 antisense oligonucleotides might affect the expression of NF-kappa B p65 and cytokines in lamina propria mononuclear cells(LPMC) from patients with ulcerative colitis (UC). LPMC were isolated from intestinal mucosal biopsy specimens from 3 patients with UC, and cultured with or without NF-kappa B p65 antisense oligonucleotides (5'-GGAACAGTTCGTCCTATGG-3'), missense oligonucleotides (5'-GGAACAGTTCGTCTATGG-3') and dexamethasone. NF-kappa B p65 expression was determined by western blot analysis. The expression of cytokine mRNA was studied by reversal transcription-polymerase chain reaction (RT-PCR). The cytokine levels were measured by enzyme linked immunosorbent assay. The results showed that NF-kappa B p65 antisense oligonucleotides resulted in down-regulation of NF-kappa B p65 expression, blocked the expression of IL-1 beta mRNA and IL-8 mRNA, and strikingly reduced the production of IL-1 beta and IL-8, and these effects were greater than those of dexamethasone in cultured LPMC from patients with UC(P < 0.05). Therefore, the application of NF-kappa B p65 antisense oligonucleotides may serve as a novel molecular approach for the treatment of patients with UC.

Objective To investigate the inpatients′satisfaction with the hospital environment,medical process,medical skills and service attitudes,in order to provide evidence for improving the hospital cultural construction and patients′satisfaction level.Methods According to the stratified sampling by the department,the study investigated 521 inpatients from a second-class hospital using questionnaire survey.Results Approximately 62.2% of the participants were satisfied with the “hardware”of the hospital culture and 66.8% were satisfied with the “software ” of the hospital culture.However,there were no statistical differences between these satisfactions (χ2 =0.046,P >0.05).Conclusions A considerable proportions of the participants are not satisfied with the current hospital culture.Thus,the hospitals should enhance their cultural construction and education,as well as improve the medical procedures and technical skills,in order to promote patients′rehabilitation and satisfaction level.
