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.

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.

OBJECTIVETo compare the long-term survival and postoperative complications of distal gastric cancer patients between Billroth I((BI() and Billroth II((BII() reconstruction.
METHODSClinicopathological data of 992 patients with distal gastric cancer who underwent D2 curative gastrectomy in our department from May 2008 to April 2015 were recorded, including 207 patients of BI( reconstruction and 785 of BII( reconstruction, were retrospectively analyzed. Patients presenting a previous history of cancer, gastric resection or cytotoxic chemotherapy, and those presenting liver or intraperitoneal tumor dissemination or unresectable infiltration into contiguous organs were excluded. Patients in BI( and BII( group were selected using gmatch methods based on age (±10 years), gender, tumor size (±1 cm), differentiated degree and depth of invasion in order to reduce the selection bias of clinicopathological characteristics. The final number of patients matched was 191 respectively.
RESULTSCompared with BII( group, the BI( group had a significantly shorter operation time (181.7 min vs. 220.7 min, P=0.000) and a shorter postoperative hospitalization stay (7.6 days vs. 8.1 days, P=0.046). The postoperative complications including anastomotic leakage, wound dehiscence, wound infection, intraperitoneal hemorrhage, intestinal obstruction, duodenal stump fistula, pulmonary infection and fever had no significant difference(P>0.05). Three-year survival between two groups was comparable (82.9% vs. 78.7%, P=0.379).
CONCLUSIONSCompared with BII(, BI( reconstruction is more suitable for patients with distal gastric cancer.

OBJECTIVETo investigate the relationship of ABO blood group with the clinicopathological characteristics in patients with gastric cancer and to assess whether the ABO blood group was associated with prognosis.
METHODClinicopathological and follow-up data of 2838 patients with gastric cancer who underwent radical gastrectomy in our department from June 2008 to October 2013 were analyzed retrospectively. The distribution of ABO blood group under different clinicopathological characteristics and the overall 5-year survival of ABO blood group were compared.
RESULTSThere were no significant differences in clinicopathological characteristics among patients with different ABO blood groups (all P>0.05). The 5-year overall survival(OS) rates were 57.3% for patients with blood type A, 54.7% for type B, 57.4% for type O, and 53.5% for type AB. Though there was no significance difference of survival among ABO blood groups(P=0.722), while the subgroup analysis indicated that stage III( patients of blood group Non-AB had a poorer OS compared to those of blood group AB(25.2% vs. 44.7%, P=0.014); smoking patients of blood group Non-AB had a poorer OS compared to those of blood group AB(53.4% vs. 74.9%, P=0.044).
CONCLUSIONNeither clinicopathological characteristics nor overall survival are associated with the ABO blood group, however, stage III( and smoking patients of blood group Non-AB have a poorer OS compared to those of blood group AB.
