BACKGROUND:Metabonomics has been proved to analyze and observe the pathological process of rat myocardial infarction and the underlying mechanism. OBJECTIVE:To further analyze the metabolomic pathways of bioinformatics in rat models of myocardial infarction. METHODS:The experimental studies about rat myocardial infarction were retrieved from CNKI, WanFang, CqVip, PubMed and Embase databases. The metabolic products described in the literatures were col ected and summarized. Signaling pathways were analyzed using KEGG database molecular function annotation, the enzymes, translocators and their properties were analyzed by HMDB database. Metabolites pathway were visualized with MetPA. RESULTS AND CONSLUSION:A total of 26 metabolic products were identified in the included literatures and mainly participated in 29 metabolic pathways. Through topology analysis, 5 of the 10 metabolic pathways were selected and regarded as the metabolic pathways of myocardial infarction in rats, including aminoacyl-tRNA biosynthesis;glycine, serine and threonine metabolism;valine, leucine and isoleucine biosynthesis;biosynthesis of unsaturated fatty acids;phenylalanine, tyrosine and tryptophan biosynthesis. In conclusion, the bioinformatics analysis of metabolites in rats with myocardial infarction show that myocardial infarction is related to the metabolism and metabolic pathways of carbohydrates, proteins, fat and RNA.

Objective To observe the effects of hyperbaric oxygen (HBO) on the expression of FasL mRNA and caspase-3 protein in renal tissue after renal ischemia-reperfusion injury (IRI) in order to elucidate the underlying mechanisms.Methods Rats were randomly divided into thrcc groups: sham group(n=8),IRI group(n=8) and IRI+HBO group(n=8).The IRI group and the IRI+HBO group recieved 45 minutes hibateral renal ischima and the IRI +HBO group received additional HBO therapy at the 1st,24th and 48th hour after ischemia.The kidneys were removed at the end of HBO therapy.Malondialdehyde (MDA) level and superoxide dismutase (SOD) activity were measured to determine the extent of oxidative stress.The expression of FasL mRNA and caspase-3 protein was detected by quantitative real-time PCR and immunohistochemical staining in renal tissue respectively.Results Compared with the sham group,MDA level increased markedly and SOD activity decreased markedly after ischemia.After HBO treatment,MDA level decreased and SOD activity increased significantly (P ＜0.05).In IRI group,the expression of FasL mRNA and caspase-3 protein were higher than those in the sham group (P＜0.01),which were reduced significantly by HBO treatment (P＜0.01).Conclusion The expression of FasL mRNA and caspase-3 protein increases along with the lasting of reperfusion and HBO exhibites protection against cell apoptosis through improving the antioxidant-oxidant balance and reducing IRI in acute stage of IRI.

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.
