Objective To investigate the role of intestinal fatty acid binding protein (IFABP) and blood procalcitonin (PCT) in diagnosis of traumatic Intestinal rupture in early stage.Methods The clinical data of 58 patients with abdominal injuries admitted from May 2012 to April 2016 were retrospectively analyzed.All 58 patients were divided into intestinal rupture group (n =21) and nonintestinal rupture group (n =37).The concentrations of IFABP and PCT were detected,analyzed and compared between two groups at different intervals.Results The IFABP and PCT in intestinal rupture group were significantly higher than those in non-intestinal rupture group.The IFABP and PCT in intestinal rupture group significantly decreased after operations.There were significantly differences in IFABP and PCT between two groups at admission,4 hours after admission,preoperative period,and 24 hours after operation.However,these differences disappeared at 72 hours after operation.At the same time,the accuracy rate 92.4%,sensitivity 96.3%,specificity 72.8% found in combination of these two biomarkers were significantly higher than those of IFABP and PCT measured separately.Conclusions The combination of IFABP and PCT detection can be used as an indicator for the diagnosis of traumatic intestinal rupture in the early stage.

Objective To investigate the utilization of damage control surgery (DCS) in treatment of the severe abdominal traumas.Methods The clinical data of 56 patients with severe abdominal traumas treated by DCS (Emergency operation,fluid resuscitation and definitive operation were used gradually.)from January 2011 to January 2013 in Department of General Surgery,Taizhou People's Hospital were retrospectively analyzed.Results Of the 56 patients,52 were cured and discharged from hospital,the clinical curative rate was 92.9%; 4 patients dead.Conclusions Abdominal traumas under going operations by applying the damage control surgery significantly increased the clinical curative rate.

OBJECTIVETo observe the effect of SIRT1 on intestinal barrier function of epithelial Caco-2 cells under hypoxia and investigate its mechanism.
METHODSCaco-2 cells were randomly divided into three groups: normoxia group (Nx), hypoxia group (Hx,1%O2 for 6 h) and hypoxia plus 40 μmol/L Resveratrol (agonist of SIRT1) group (Hx+Res). Transepithelial electrical resistance (TER) was determined. mRNA and protein expressions of SIRT1 and tight junctions (ZO-1, Occludin, Claudin-1) were examined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting.
RESULTSBoth mRNA and protein expressions of SIRT1 were significantly reduced in Hx group as compared with Nx group (0.40±0.02 vs. 0.70±0.07, P=0.001; 0.37±0.03 vs. 0.76±0.03, P=0.001). The mRNA and protein expressions of SIRT1 were significantly increased in Hx+Res group as compared with Hx group(0.50±0.02 vs. 0.40±0.02, P=0.026; 0.54±0.02 vs. 0.37±0.03, P=0.011). The expression levels of ZO-1, Occludin and Claudin-1 in Hx group were lower than those in Nx group (P<0.05), however, pretreatment with Resveratrol could attenuate the decreased expression of above 3 molecules under hypoxia(P<0.05). TERs of Nx group, Hx group and Hx+Res group were (142±7) Ohm/cm(2), (94±3) Ohm/cm(2) and (119±7) Ohm/cm(2) respectively. Compare with the Nx group, the TER of Hx group was significantly decreased(P<0.05). TER of Hx+Res group was significantly increased compare with Hx group, but it was still significantly lower than that in Nx group(P<0.05).
CONCLUSIONSExpression of SIRT1 is significantly reduced under hypoxia. Activation of SIRT1 can maintain the epithelial barrier function through regulating the expression of tight junctions under hypoxia.

Objective To explore the value of trauma-care check list (TCC) and quick sequential organ failure assessment (qSOFA) on the early diagnosis of severe trauma with sepsis,and analyze the treatment time lines.Methods Totally 120 patients with severe trauma treated in Taizhou People's Hospital from February 2017 to January 2018 were reviewed.Sixty cases adopted TCC and qSOFA trauma care integration process (integration group),and the rest 60 cases adopted systemic inflammatory response syndrome (SIRS) score and emergency surgery multi-section support process (traditional group).According to the 2016 International Sepsis Guide Criteria,the diagnostic sensitivity and specific degrees of the two groups were calculated.The treatment time node,blood loss,complication rate,postoperative survival rate,and the total length of hospital stay of the two groups were analyzed.Results Of the 60 cases in the integration group,32 cases were confirmed severe trauma with sepsis,and 27 cases were confirmed in 41 primary diagnosed patients,with a diagnostic sensitivity of 84.38% and a specific degree of 50.00%.In the traditional group,30 cases were confirmed severe trauma with sepsis,and 25 cases were confirmed in 38 primary diagnosed patients with a diagnostic sensitivity of 83.33% and a specific degree of 56.67%.The significant shorter MDT consultation time,primary diagnosis time of sepsis,the duration from injury to surgery time and total hospitalization time were statistically significant different between the two groups (P<0.05).Patients in the integration group had significantly lower incidence of postoperative complications and 28-day fatality rate,but there was no significant difference between them (P>0.05).Conclusions TCC and qSOFA score in the treatment of severe trauma can optimize salvage process,significantly shorten the treatment time,and reduce postoperative complications.Moreover,qSOFA score and SIRS score have the same effect on the early diagnosis of sepsis in patients with severe trauma.
