RESUMO
Inquiry is the main method of history taking. The training should not be limited to the medical inpatients inquiry. Different training scenes should be taken. The outpatient history inquiry needs a similar clinic room and set time limit, and focuses on key point history inquiry as well as document writing. Some principles in emergency inquiry are introduced, such as SAMPLE principle. The key points of inquiry of different patients including elderly patients, child patients, traumatic patients and drug addiction patients are also introduced. Through the combination of theory and practice mode, the group discussion and role-play, different scenes design and standardized patients application, reasonable design of teaching hours and content distribution, as well as feedback in time, optimal teaching effect can be finally achieved.
RESUMO
Objective To investigate the effects of B.adolescentis and L.acidophilus in treatment of dextran sulphate sodium (DSS)-induced ulcerative colitis(UC) in mice and their potential mechanisms. Methods Seventy-five BABL/C mice were randomly divided into control,saline (NS),B.adolescentis BF0624 treatment (B),L.acidophilus LT0637 treatment (L) and salicylazosulpha-pyridine treatment (S) groups.Except control group,the other four groups were received DSS to induce ulcerative colitis. The weight-loss,fecal trait and bleeding were recorded every day.Colonic length and histological scores were evaluated on day 3,5 and 7.The gene and protein expression of hot shock protein (HSP)70, glucocorticoid receptor (GR),interleukin (IL)-10 and tumor necrosis factor (TNF)-α were detected by Western blot and reverse polymerase chain reaction (RT-PCR) respectively.Results B.adolescentis BF0624 and L.acidophilus LT0637 could relieve the inflammatory reaction of the experimental UC.The DAI scores were 1.84±0.4 in L group on day 3,which was lower than that in NS group (2.8±1.0).The DAI scores in all treatment groups were decreased on day 5.Compared with NS group[(8.1±0.6)cm ], the colon length on day 8 were (9.0±0.6)cm in B group,(9.35±0.6)era in L group and (8.8±1.1)cm in S group (P＜0.05).The colonic mucosa was improved pathohistologically in L group (6.0±1.0) on day 8.The expression of HSP70 and IL-10 in B and L groups were up-regulated and the expression of TNF-α was down-regulated.Conclusions Both B.adolescentis BF0624 and L.acidophilus LT0637 were effective in treatment of acute ulcerative colitis.The potential mechanism of two probiotics may be related with up-regulation of HSPT0 and IL-10 expressions and down-regulation of TNF-α expression.
