Objectives To evaluate plain radiographs and computed tomography (CT) scans in respect of assessment of articular fragment displacements (step and gap) in displaced acetabular fractures. Methods A retrospective evaluation was done to analyze the CT scans and plain radiographs of 64 patients who had been treated for displaced acetabular fractures in our hospital from January 1998 to May 2003. Of them, 20 met the inclusion criteria. In a blind method, 3 independent reviewers measured step and gap deformities on plain radiographs and CT scans utilizing a standardized measurement technique. The sensitivity and specificity of plain radiographs in detecting step and gap displacements (2 mm and 4 mm) in comparison of those of CT scans were determined. Moreover, intraclass correlation coefficient and intraobserver reliability were also calculated. Results Compared with CT, plain radiographs showed poor sensitivity in detecting step deformity (sensitivity = 44.3%). As far as fracture type was concerned, plain radiographs were particularly poor at detecting step deformity in fractures involving a single column of the acetabulum (sensitivity = 0%). Excellent intraobserver and intraclass reliability existed among the 3 reviewers. Conclusions Compared with CT scans, plain radiographs are poorly sensitive in detection of step and gap deformities in patients with acetabular fractures, and particularly poor at detecting step deformities. Therefore, in treatment of displaced acetabular fractures, CT scans are essential and should not only be used together with plain radiographs in the preoperative evaluation but also be considered in the postoperative assessment of fracture reduction and predicting future outcomes.

Objective To explore the ursodeoxycholic acid efficacy and safety analysis of nucleoside drugs for HBeAg-positive with high viral load in patients with liver cirrhosis, and its effect on peripheral blood Th17, Treg levels.Methods 80 patients with high viral load B HBeAg-positive from November 2012 to February 2014 were selected and randomly divided into control group and observation group, 40 cases in each group.Patients in control group received conventional treatment, observation group was treated with ursodeoxycholic acid based on the control group, antiviral efficacy and adverse reactions, peripheral blood Th17, Treg levels were compared between two groups.Results After treatment, the ALT, AST, ALB, TBil levels between two groups were significantly lower compared with before treatment(P<0.01), the ALT, AST, ALB, TBil levels in observation group were significantly lower than the control group ( P<0.01 ); HBV-DNA negative rate ( 85.0%) and decrease of HBV-DNA in observation group were significantly higher (7.5%) than those in control group, the difference was statistically significant (χ2 =48.322, t =11.490, P<0.01); ALT normalization rate (52.5%), HBeAg seroconversion rate (57.5%) in observation group was significantly higher than those in control group(15.0%, 17.5%), the difference was statistically significant (χ2 =12.579,χ2 =13.653, P<0.01);complications compared with the situation observed group of death, hepatocellular carcinoma, spontaneous bacterial peritonitis, gastrointestinal bleeding compared with control group, the difference was not statistically significant (χ2 =1.01, χ2 =2.05, χ2 =3.12, χ2 =0.21, P>0.05).After treatment, the Th17 levels elevated, Treg level decreased in two groups, Th17 level in observation group was significantly higher than control group, Treg levels were significantly lower than the control group, Th17/Treg ratio was higher than the control group (P<0.05).Conclusion Ursodeoxycholic acid can significantly improve liver function of patients with HBeAg positive with high viral load, increase the rate of HBeAg seroconversion, inhibit HBV viral replication and delay progression of the disease, and less adverse reactions.It can increase the number of Th17 cells, reduce the number of Treg cells in patients, which may be one of its antiviral mechanism.

ObjectiveTo observe the effect on stress response to indwelling gastric tube assisted by bronchofiberoscope and traditional way in patients with severe craniocerebral injury in intensive care unit(ICU). Methods 126 patients admitted in Department of Surgery ICU in Lanzhou University Second Hospital were randomly divided into bronchofiberoscope assisted indwelling gastric tube group(experimental group) and the traditional way of indwelling gastric tube group(control group), 63 cases in each group. In the experimental group, the rod of mirror, Olypus BF-P60, was coated with lidocaine gel, through the nasal cavity it was sent into interior, when arrived at epiglottis, the operator adjusted the mirror head and let it go into the esophagus(about 10 cm), then put a steel wire as a guide into a hole for biopsy, and simultaneously, as the operator pulled out the rod, the wire was continuously pushed slowly further inside; after the bronchofiberoscope was completely withdrawn, valelinum liquidum was used to ensure sufficient lubrication to the external and internal walls of the indwelling gastric tube ready to be sent into the stomach, afterwards the tube was slowly pushed along the guide wire to an appropriate location and then the wire was pulled out, the operator injected air, when he or she heard the gurgling sound as the gas passing water, fixed the tube. In the control group, the traditional way of indwelling gastric tube was applied. Before and after indwelling gastric tube for 1, 3, 5 minutes, the changes of systolic pressure(SBP),diastolic pressure(DBP),heart rate(HR), end-expiratory carbon dioxide partial pressure(PETCO2) and plasma concentrations of norepinephrine(NE), adrenaline, angiotensinⅡ(AngⅡ), glucose(GLU) were examined.Results The plasma levels of SBP, DBP, HR, PETCO2, adrenaline, NE, AngⅡ and blood GLU had no statistical significant differences before operation in comparisons between both groups(allP>0.05). Compared to those before indwelling the tube, the levels of SBP, DBP, HR, PETCO2, NE, adrenaline, AngⅡ and GLU at various time points after the indwelling in experimental group were of no statisticalsignificant differences(allP>0.05), while the levels of SBP, DBP,HR, adrenaline, NE, AngⅡand GLU in control group at various time points after indwelling were higher obviously than those before operation, and the level of PETCO2 was decreased significantly compared with that before operation. The differences in the above indexes were significant between the treatment and control groups at 1 minute after indwelling〔SBP(mmHg, 1 mmHg=0.133 kPa): 125.1±15.4 vs. 135.5±13.6, DBP(mmHg): 85.6±16.1 vs. 91.1±17.2, HR(bpm): 99.4±13.8 vs. 107.9±16.5, PETCO2(mmHg): 32.5±2.8 vs. 29.8±4.1, NE(ng/L): 365.4±29.7 vs. 475.7±49.9, adrenaline(ng/L): 75.4±7.2 vs. 83.6±7.4, AngⅡ(ng/L): 65.3±6.9 vs. 73.3±9.1, GLU(mmol/L): 10.1±1.9 vs. 13.4±3.0, allP<0.05〕; the differences in the above indexes remained significant between the treatment and control groups till 5 minutes after indwelling〔SBP(mmHg): 123.7±14.8 vs. 129.7±15.1, DBP(mmHg): 84.3±14.6 vs. 88.4±14.2, HR(bpm): 97.7±13.6 vs. 31.6±3.9, PETCO2(mmHg): 33.5±3.1 vs. 31.6±3.9, NE(ng/L): 363.9±31.3 vs. 457.7±48.4, adrenaline(ng/L): 74.6±7.8 vs. 83.5±8.5, AngⅡ(ng/L): 64.3±8.4 vs. 71.9±5.9, GLU(mmol/L): 9.6±2.3 vs. 12.7±3.1, allP<0.05〕.ConclusionCompared with traditional way, the indwelling of gastric tube assisted by branchofiberoscopy can induce milder stress response.
