Objective To explore the effects of baicalin on the expression of ICAM-1 in lung injury induced by severe acute pancreatitis(SAP). Methods SAP model was induced by injection of 62mmol/L sodium taurocholate solution into biliopancreatic duct. A total of 72 SD rats were randomly divided into 3 groups: sham operation group, SAP group and SAP treated with BA group. Myeloperoxidase(MPO) activity in lung tissue was examined at 3, 6 and 12h. The expression of ICAM-1 in lung tissue was determined by immunohistochemical technique. The pathological changes of pancreas and lung tissue were examined under optical microscope. Results The levels of MPO activity, which were similar between SAP group and Baicalin group in the early 3 hours, were dramatically lower in Baicalin group at 6h, 12h(P

Objective To investigate the association between social support and family cohesion, adaptability of rural patients undergoing maintenance hemodialysis (MHD). Methods Between August 2012 and November 2012, 94 patients with incident hemodialysis from rural areas in Hebei province were consecutively recruited in the study. The social support inventory (SSI) and the Chinese version of the family adaptability and cohesion evaluation scales (FACESII-CV) were employed in the investigation 3 months after the start of hemodialysis. Pearson correlation analysis was used to estimate the relationship between social support and familiarity, adaptability in rural MHD patients. Results The score on the family cohesion the adaptability were lower than norm(all P<0.001). The social support was associated with family cohesion and adaptability. The total scores on social support, emotional support and material support were positively associated with the scores on the family cohesion and adaptability (P<0.05). Conclusions The family cohesion and adaptability in rural patients undergoing hemodialysis are both at a lower level and are closely related to emotional and material supports. The higher they get social support, the higher the levels in family cohesion and adaptability.
