ABSTRACT

Objective To assess the value of noninvasive MR imaging biomarkers in evaluating the early efficacy of anti?angiogenesis drugs. Methods Subcutaneous colon cancer xenograft models in thirty nude mice were established. The mice were randomly divided into three groups (n=10 for each): avastin injection group (dose 10 mg/kg), fluorouracil group (dose 150 mg/kg), physiological saline group (dose 20 mg/kg). Dynamic contrast?enhanced (DCE?MRI) and multiple b value diffusion weighted imaging (muti?b?value DWI) were acquired before or 1 h, 24 h and 48 h after the treatment. The parameters of contrast transfer coefficient (Ktrans), reflux constant (Kep), plasma volume fraction (Vp), extravascular extracellular volume fraction (Ve) and various apparent diffusion coefficients (ADCs) (ADC10b, ADChigh and ADCperf) were measured. Forty eight hours after the treatment, the mice were sacrificed following MRI. Aimmunohistochemical examination determined microvessel density (MVD) and proliferating cell nuclear antigen (PCNA) score. A repeated measures analysis of variance was used to compare the difference between the quantitative parameters among the three groups. A multivariate variance analysis was performed to compare the difference between the parameters at the same time point among the three groups. The correlation between MRI quantitative parameters with MVD and PCNA score were analyzed by Pearson and Spearman correlation analysis respectively. Factor analysis method summarized MRI quantitative parameters. Results One hour after the treatment, the parameters of Ktrans, Kep, ADC10b, ADChigh and ADCperf value immediately changed, they were(0.009 ± 0.005)/s,(0.042 ± 0.031)/s,(0.043 ± 0.002)× 10?3 mm2/s,(0.031 ± 0.005)× 10?3 mm2/s,(0.089 ± 0.006)× 10?3 mm2/s, Ktrans, Kep, ADC10b and ADChigh values all had significant differences in the three groups (F=42.058, 25.979, 9.870 and 8.511, respectively, all P<0.05). There were also statistical difference in the change trend of the above parameters among the three groups (F=22.108, 7.280, 65.698 and 19.900, respectively, all P<0.05). The change trend of ADCperf showed significant difference among the three groups (F=38.780, P<0.01). Ktrans, Kep and ADCperf positively correlated with the MVD count and PCNA score (r values were 0.421 to 0.811, both P<0.01), while ADC10b showed a negative correlation (r=-0.656 and-0.560, both P<0.01), ADChigh had negative correlation with the PCNA score (r=-0.568, P<0.05). Ktrans, Vp, Kep and ADCperf were classified as tumor microcirculation factor, whereas ADC10b and ADChigh were normalized for cell metabolism factor through the factor analysis. Conclusions Combination of DCE?MRI and muti?b?value DWI can reflect the early changes of drug therapy from the aspects of tumor microcirculation and cell metabolism. Ktrans, Kep, ADCperf, ADC10b and ADChigh can be taken as noninvasive imaging biomarkers to quantify the early efficacy of anti?angiogenesis drugs.

ABSTRACT

Objective To compare the value of acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ),sequential organ failure assessment (SOFA) and procalcitonin (PCT) in assessment of severe multiple trauma. Methods A retrospective study was carried out on clinical data of patients with severe multiple trauma who were admitted to ICU from July 1 st 2010 to October 31 st 2011.PCT detection,APECHE Ⅱ and SOFA scoring were routinely performed for all the patients within 24 hours,and were performed again one week later for the patients who were complicated with sepsis within one week.Results The score of APACHE Ⅱ and SOFA in septic shock group was higher than that in severe septic and septic groups (P <0.01 ),while PCT level among septic,severe septic and septic shock groups had no statistical difference (P > 0.05).To determine the predicting accuracy of APECHE Ⅱ score,SOFA score and PCT,receiver operating characteristic curve (ROC) was constructed.The areas under the curve (AUC) for APECHE Ⅱ score,SOFA score and PCT in predicting the emergence of sepsis on admission was 0.615,0.663 and 0.160 respectively.AUC for APECHE Ⅱ score,SOFA score and PCT in predicting the occurrence of death among the severe multiple trauma patients on admission was 0.576,0.571 and 0.619 respectively.AUC for APECHE Ⅱ,SOFA and PCT in predicting the death of patients complicated with sepsis at one week after admission was 0.746,0.837 and 0.600 respectively. Conclusions Among the APACHE Ⅱ score,SOFA score and PCT,APACHE Ⅱ and SOFA score are better than PCT in assessing the infection severity of sepsis.SOFA score is the best in predicting the occurrence of sepsis,while PCT is the worst.PCT is the best in predicting the occurrence of death of severe multiple trauma patients,while SOFA score is the worst.SOFA score is better than APACHE Ⅱ score and PCT in predicting the occurrence of death of the patients complicated with sepsis.

ABSTRACT

Objective To compare the effectiveness and advantage of salvage liver transplantation post-resection with primary liver transplantation for HCC patients. Methods Medline, Embase, Cochrane, CBMdisc, CNKI and Wanfang Database were searched. Randomized and nonrandomized controlled trials comparing primary liver transplantation with salvage liver transplantation were analyzed. Ten retrospective studies involving 1115 patients were included. 164 received salvage liver transplantation,and 951 patients received primary liver transplantation. Results In most researches, the two groups of patients were similar for age, sex,and cirrhosis severity at time of transplantation. Some researches showed no difference in tumor size and number between the two groups. Few studies referred to microvascular invasion. Most of the researches showed there was no significant difference in blood loss,operative time,overall survival and disease-free survival between the two groups. Conclusion Compared to primary liver transplantation, salvage liver transplantation after liver resection is associated with similar operative time, risks and overall survival. Resection first and salvage liver transplantation for recurrent tumors or liver failure seem to be a feasible treatment strategy for hepatocelluar carcinoma,especially in early-stage.

ABSTRACT

Objective To study the effects of enteral immunonutrition on immune function in patients with multiple trauma. Method A total of 32 patients with multiple trauma admitted to general ICU in ChangZheng hospital, Shanghai from March 2007 to May 2008 were randomly (random number) divided into two groups,enteral immunonutrition group (EIN group, n = 16)and the general formula enteral nutrition group (EN group, n = 16).Two groups of patients on the third day after injury began to accept the EIN and the general formula EN which respectively support at least 14 days. The patients peripheral blood lymphocyte count (TLC), immunoglobulin (IgG,IgM, IgA) ,and T-lymphocyte subsets (CD3, CD4, CD8, CD4/CD8) were detected on the day of the group formation, the seventh and the fortteenth day of the nutritional support. Results TLC, IgG, IgM, IgA, CD4 and CD4/CD8 ratio were significantly higher in EIN Group on the 7th and 14th day than that on the first day ( P <0.05), and extended with the EIN and sustained increase. All immunization indicators of EN group on the 7th day were no significant changes compared with the day of the group formation, and on the 14 th day TLC, IgG, IgM,IgA, CD4 and CD4/CD8 ratio were significantly higher than that on the day of the group formation ( P < 0.05),but were significantly lower than that in the EIN group on the 14th day ( P < 0.05). Conclusions Compared with the general formula EN, EIN is more helpful to restore and increase the humoral and cellular immune function in early post-multitraumatic phase.

ABSTRACT

Objectives To explore the expression of HER4 and VEGF in NSCLC and elucidate the relationship between their expression and the characteristic of clinical pathology. Methods 82 cases of paraffin-embedded tissues from informative NSCLC were used to detect the expression of HER4 and VEGF by means of immunohistochemical assay. Results HER4 is overexpressed in 65;9%of NSCLC cases. The overexpression of HER4 is correlated with the lymph node metastasis and TNM staging. VEGF is expressed in 53.7%of NSCLC cases. The expression of VEGF is also correlated with the lymph node metastasis and TNM staging, and the expression of VEGF is correlated with the overexpression of HER4.Conclusions HER4 and VEGF are the protein to regulate the growth of NSCLC and it might be a good way for the treatment of NSCLC by suppressing the overexpression of HER4 and VEGF.

ABSTRACT

Objective To investigate the delivery efficacy of periadventitial delivery of 125I-iododeoxyuridine (125I-IUdR) in comparison of intravascular delivery to determine the optimal delivery method for inhibiting post-angioplasty restenosis. Methods In 8 pigs, one side carotid, subclavian and iliac arteries of each pig were injured by balloon angioplasty with a 20% overstretches. Then, 4 mCi of 125I-IUdR was delivered at each targeted vessel with periadventitial method in 4 pigs (periadventitial group) and with intravascular method via a porous balloon catheter in other 4 pigs (intravascular group). The animals survived for 5 hours and the blood radioactivity was investigated prior to and hourly after procedure until sacrifice. The targeted vessels and renal arteries (for control) were harvested for gamma-counting and histological observation. Meanwhile, the radioactivity in thyroid, liver, bladder, small bowel and each kidney also were measured to determine the biodistribution of 125I. The activities of 125I presented in arterial and tissue specimens were compared between the two delivery groups. The targeted arteries were histologically observed and the ratio of intima to media (I∶M ratio) was calculated. Results The target arterial walls in the periadventitial group had 3.4 times as much of 125I radioactivity as in the intravascular group, respectively (P=0.038); the blood activity in intravascular group was significantly higher than periadventitial group immediate after procedure (P0.05). The mean I: M ratios in both groups were 0.05 without additional injury at the vessel wall. Conclusion The periadventitial delivery offered substantial advantage over intravascular approach with high local delivery efficacy. The apparent redistribution rate is more rapid following intravascular delivery.

ABSTRACT

Objective To investigate CT examination in the evaluation of the percutaneous radio frequency ablation (RFA) in the treatment of hepatic carcinoma.Methods 50 cases of hepatic carcinoma (including primary hepatic cancer 36 and hepatic metastases 14) with 76 lesions treated by RFA associated with pre and post procedure data of CT follow up were analyzed retrospectively. CT examinations including plain and contrast enhanced CT scanning were carried out at 1 week and 3 weeks after the RFA, but sometimes with furthermore intermittent scanning at 3~6 months. Results Complete ablation of the tumors occurred in 49 lesions (64.5%) of 35 cases and incomplete ablation of tumors happened in 27 lesions (35.5%) of 18 cases. Among RFA treated 76 lesions, there were 9 with internal hemorrhage, 1 with abscess formation. 3 cases showed intraperitoneal bleeding; 6 cases demonstrated reactive pleural effusion and 1 case revealed with small amount of pneumothorx.Conclusions The contrast enhanced CT scanning provides a great diagnostic value for evaluation of the efficacy of hepatic tumor treated by RFA and also the local recurrence and complications.
