Acta Nutrimenta Sinica 1956;0(04):-
Objective:To study the influence of dietary restriction on the expression of insulin signaling pathway genes in mouse adipose tissue. Method:Twenty four C57BL/6 male mice of 2 w age were subjected to either AL (ad libitum) or DR (dietary restriction, 40% from AL) randomly until sacrificed.Then the epididymis fat pads were weighed, and their insulin signaling gene expression was detected by Oligo Insulin Signaling Pathway Microarray (SuperArray), and two of the differentially expressed genes, NPY and AKT3 were validated by Real Time PCR. Results:Dietary restriction significantly reduced the weight of epididymis fat pads and 31 (20 up, 11 down regulation) of 96 insulin signaling pathway genes were differentially expressed. The results of Microarray coincided with that of Real Time PCR. Conclusion:The differential regulation on the expressions of insulin signaling pathway gene may be the important molecular basis of dietary restriction.

Objective To investigate the effect of L-N6-(1-iminoethyl) Lysine(L-NIL) on ischemia-reperfusion (I/R) -induced lung injury in a rat model of lung transplantation. Methods Pathogen free male SD rats weighing 250-350g were used as donor and recipient rats in this study. The animals were randomly divided into 3groups (n = 6 each): sham operation group (group S); lung tratsplantation group (group L) and lung transplantation + L-NIL (selective iNOS inhibitor) group (group L-NIL). In group L and L-NIL orthotopic left lung allograft transplantation was performed. In group L-NIL 3 mg/kg was injected iv at the beginning of reperfusion. The donor lungs were removed from live donor rats and placed in Euro-collins solution at 4 ℃. The lung transplantation was performed under microscope and non-suture cuff technique was used. The implanted donor lungs were ventilated and reperfused. 0.5% Evans blue 0.2 ml was injected iv during reperfusion. The donor lungs were removed after being implanted, ventilated and reperfused for 2 h for microscopic examination and determination of iNOS, endothelial NOS (eNOS) and myeloperoxidase (MPO) activity and malondialdehyde (MDA) and Evans blue content in the lung tissue and W/D lung weight ratio. Results Lung transplantation significantly inceased W/D ratio, iNOS and MPO activity, and Evans blue and MDA content in the lung tissue and decreased eNOS activity in group L as compared with group S. L-NIL iv significantly attenuated the increase in the variables mentioned above and ameliorated capillary congestion and inflammatory cell infiltration in the lung. Conclusion Intravenous L-NIL administered at the beginning of reperfusion can reduce I/R injury to the transplanted donor lungs.

Objective Based on the Helical Ventricular Myocardial Band (HVMB) theory proposed by Torrent-Guasp,the ventricular myocardial hand extends from the root of the pulmonary artery to the root of the aorta with two helical coils.This new theory is considered as a revolutionary concept for further understanding the global, three-dimensional and functional architecture of the ven- tricular myocardium. No repot had described techniques for disecting HVMB while keepin~ the integrity of the coronmy artery sys- tern. We explored techniques for dissecting HVMB in swine.Methads 33 fresh swine hearts were randomly divided intoll groups, 3 bearts in each. 160% barium sulfate (type I)suspmmion was injected into the coronary artery system. The coronary arteries were li- gated. The strial tissue was removed following puuing the hearts in boiling water then cooling for several hours. The superficial coro- nary vessels and fat tissue around the atrio-ventricular taxi inter-ventricular sulcus we~'e preserved. Some branches of the left anterior descending artery, distal segment, of posterior descending branch, and middle and distal segment of obtuse marginal branches were mu- tilated appropriately. HVMB dissection was completed with fingers in accordnce with Torrent Guasp' s technique. Results A contin- ued bundle of muscle, originated at the root of pulmonary artery and ended at the root of aorta, was unwrapped along the major dire- tion of the cardiac muscle fiber in all of the 33 hearts with spating of the coronary artery. The swine hearts' ventricular myocandium was cumosed of two loops, with basal loop firm the root of the pulmonart artery to the anterior papillary muscle and apical from the beginning of the anterior papillary muscle to the root tithe aorta. Each loop consisted of two segments: the right segment-coincid- ing with the right ventricular free wall and the left segment-coinciding with the basal d the left ventricular free wall. Posterior papillary muscle, which belongs to the descendant segment, denmrcated the border between the descendent and the ascendant of the HVMB's apical loop. Conclusion Although controversies about the theory of the HVMB remain, we have dissected the HVMB in the swine hearts' ventricular myocardium successfully with sparing of the coronary artery systems. This dissection procedure provides technical information for the studies of associated diseases based on the theory of HVMB.
