Objective To assess the efficacy of whole body diffusion weighted imaging (WB-DWI) in detecting pediatric primary and metastatic malignant tumor. Methods WB-DWI was performed in 62 healthy pediatric volunteers and 40 pediatric patients with confirmed malignant tumors. The healthy volunteers were divided into three groups: 0 to 12 months, more than 12 months to 5 years and more than 5 to 15 years. The characteristics of WB-DWI imaging were analyzed. McNemar test was used to compare the difference of detection on metastasis between WB-DWI and WB-DWI combined with MRI, CT. The mean apparent diffusion coefficient ( ADC ) values of primary tumors and metastases were measured by using paired t test and compared with those of corresponding body regions of control group. Results WB-DWI imaging shows that signal intensity of metaphysis gradually reduces with increasing age in the normal pediatric group. On WB-DWI primary malignant tumors showed 100％ (40/40) high signal intensity and metastases showed high signal intensity in 89.2％ (58/65) on WB-DWI, with a positive predictive value of 90. 6％ (58/64). The detecting rate for metastases increased to 95.4％ (62/65) when WB-DWI was combined with MRL/CT, with a positive predictive value of 95.4％ (62/65) there was no statistically significant difference ( x2 = 2. 25, P ＞ 0. 05 ). The ADC values of primary malignant tumor sites in head ( n = 5), liver(n=6), kidney(n=8), adrenal(n=ll) were (0.76 ±0. 19) ×10-3 , (0. 97 ±0.29) × 10-3,(0. 81 ±0. 12) × 10-3 and (0. 93 ±0. 28) × 10-3mm2/s and those of corresponding body regions of control group were (1.02 ±0. 11) × 10-3,(1.57 ±0.58) × 10-3, (1.19 ±0. 15) × 10-3 and (2.03 ±0.42) ×10-3mm2/s respectively, there were statistically significant difference( t values were 3.54,3. 84,7. 02 and 12. 57 ;P ＜ 0. 05 ). The A DC values of metastases sites in head ( n = 9 ), liver ( n = 13 ), kidney ( n = 17 ),bone(n =7) and lymph node(n =6) were (0. 88 ±0. 12) × 10-3, (0. 98 ±0. 10) × 10-3, (0. 89 ±0. 11 ) × 10-3, (0. 96 ±0. 15) × 10-3 and (0. 83 ±0. 14) × 10-3mm2/s, and those of corresponding body regions of control group were (1.01 ±0.09) × 10-3, (1.45 ±0.39) × 10-3, ( 1.31 ±0.27) × 10-3, ( 1.34 ±0. 20) × 10 -3 and ( 0. 99 ± 0. 08 ) × 10 -3 mm2/s, there were statistically significant difference ( t values 4. 09,45.50,6. 95,14. 00 and 9. 27 ;P ＜ 0. 05 ). Conclusions Increased signal intensity is more frequently observed in metaphysis of long bone in normal children on WB-DWI. With a high detection rate for primary and metastatic malignant tumors, WB-DWI combined with conventional CT; MRI can significantly improve their sensitivity.

Objective To assess the therapeutic effects of flupentixol and melitracen tablets combined with Saccharomyces boulardii on patients with diarrhea-predominant irritable bowel syndrome (IBS) accompanied with anxiety and depression.Methods This multi-center,randomized,prospective study enrolled 84 patients with diarrhea-predominant IBS who were divided into combined treatment group (42 patients) and control group (42 patients).Saccharomyces boulardii was administrated in both of the groups,and flupentixol and melitracen was added in combined treatment group.The treatment course was four weeks.The gastrointestinal symptoms and mood disorders were evaluated before treatment,one week and four weeks after treatment.Adverse reactions were also observed.Chi-square test was performed for statistical analysis.Results At the end of one week after treatment,the efficacy rates of gastrointestinal symptoms improvement of combined treatment group and control group were 31.0％ (13/42) and 23.8％ (10/42),and there was no statistically significant difference (P＞0.05).At the end of four weeks after treatment,the efficacy rate of gastrointestinal symptoms improvement of combined treatment group was 92.5％ (37/40),which was higher than that of control group (73.2％,30/41),and the difference was statistically significant (x2 =5.291,P =0.037).At the end of one week after treatment,the efficacy rates of Hamilton Depression Scale score improvement of combined treatment group and control group were 31.6％ (12/38) and 12.1％ (4/33),and there was no statistically significant difference (P＞0.05).At the end of four weeks after treatment,the efficacy rates of Hamilton Depression Scale score improvement of combined treatment group was 63.9％ (23/36),which was higher than that of control group (34.4％,11/42),and the difference was statistically significant (x2 =6.433,P=0.043).At the end of one week and four weeks after treatment,the efficacy rates of Hamilton Depression Scale score improvement of combined treatment group were 35.7％ (15/42) and 80.0％ (32/40),which were higher than those of control group (15.4％,6/39 and 34.2％,13/38),and the differences were statistically significant (x2 =9.759,P=0.007; x2 =17.105,P＜0.01).One week after treatment,the adverse events rates of combined treatment group and control group were 4.8％ (2/42) and 4.8％ (2/42) ; four weeks after treatment,the adverse events rates of combined treatment group and control group were 2.5％ (1/40) and 2.4％ (1/41).There was no statistically significant difference in adverse events rates between two groups (both P＞0.05).Conclusions Flupentixol and melitracen combined with Saccharomyces boulardii treatment could not only improve the anxiety and depression symptoms of patients with diarrhea-predominant IBS,but also effectively improve gastrointestinal symptoms.The efficacy of combined treatment is better than monotherapy Saccharomyces boulardii alone treatment.

Objective To study the effect of pelvic autonomic nerve preservation(PANP)on urination and sexual function in total mesorectal excision(TME). Methods Two hundred and forty cases of male rectal cancer patients,divided into the PANP who accept the pelvic autonomic nerve preservation in TME,and the control group of 120 patients who do not.The urination and sexual function were observed and compared.3-year-survival rate,local recurrence rates of the two groups were recorded. Results The urinary disorder rates,erective disorder rates and ejaculation disorder rates of PANP group were 30.8%,28.3%and 34.2%,while values of control group were 55.0%、60.0%and 62.5%.The difference between them had statistical significance(P<0.05).The 3-year-survival rate and local recurrence rate of PANP group were 9.4%and 75.0%.The 3-year-survival rate and local recurrence rate of control group were 9.0%and 65.0%.There was no significant difference between them(P>0.05). Conclusion The PANP technique in TME could improve the urinary and sexual function of male patients without affect the prognosis.

Objective To explore the effects of beta-amyloid precursor protein (APP17) peptide on the changes in the expressions of phosphoinositide 3-kinase(PI3K), protein kinase B(PKB) and phosphorylation of cAMP response element binding protein (p-CREB) in the neurons of hippocampal gyms in rats after cardiopulmonary resuscitation. Method Twenty-one Wistar rats were randomly divided into three groups, namely the sham-operated control group, the resuscitation group and resuscitation with APP17 peptide-treated group. The rat model of asphyxial cardiac arrest was made by clamping the endotracheal tube and the standard external cardiopulmonary resuscitation ( CPR) was performed until the restoration of spontaneous circulation ( ROSC) observed.ROSC was defined by the appearance of normal QRS waves of electrocardiogram and mean artery pressure ( MAP)≥60 mmHg for more than 10 minutes. Rats of resuscitation group and control group received intravenous 0.9%NaCl, and the rats of the APP17 peptide group were treated with APP17 peptide(10μg·300 g~(-1), i. v.) after ROSC. Rats were sacrificed by decapitation after reperfusion 2 hours and then the cerebral hippocampal gyrus was immediately separated to detect PI3K, PKB and p-CREB by immunohistochemistry ( IHC) and Western-blot analysis. Statistical comparisons were made by one-way analysis of variance (ANOVA) . Results IHC showed that there was no significant difference in PDK positive cells between resuscitation group and control group (2.75 ±1.80 vs. 2.53 ± 1.53, P > 0.05) . The PDK obviously more increased in the APP17 peptide group than in resuscitation group(5.85 ± 2.83 vs. 2.75 ± 1.80, P < 0.01) .The counts of PKB and p-CREB positive cells were obviously lower in resuscitation group than those in control group (2.45 ± 1.36 vs. 5.22 ± 2.50, P < 0.05);(2.41 ± 1.11 vs. 8.31 ±3.02, P < 0.01 ). The PKB and p-CREB positive cells were significantly higher in the APP17 peptide group than in resuscitation group (9.66±4.32 vs. 2.45 ±1.36, P < 0.01);(14.18 ± 3.96 vs.2.41 ± 1.11, P <0.01). The PKB and p-CREB protein levels in resuscitation group were lower than those in the control group. Conclusions The expressions of PKB and p-CREB in neurons of hippocampus gyrus 2 hours ROSC, and APP17 peptide could restorer the expression of PDK, PKB and p- CREB and thereby protect the neurons of hippocampus gyrus from the injury of CPR.
