Objective To investigate morbidity and analyze high risk factors of nosocomial infection in patients who underwent orthotopic liver transplantation (OLT) in our ICU, in order to draft possible preventive strategies. Methods The clinical data of 56 OLT patients from Apr 2002 to Dec 2004 were analyzed. Results Significantly high APACHE Ⅱ scores and total plasma bilirubin, low platelet count were found in patients with nosocomial infection. The number of patients who had received an additional operation and broad-spectrum antibiotics before OLT were greater in nosocomial infection (NI) group than in none-nosocomial infection (NNI) group. Notably, the longer the broad-spectrum antibiotics used before OLT, the higher the morbidity rate of nosocomial infection. No significant difference was found in age, Child-Pugh grade and plasma albumin level between the two groups. In addition, APACHE Ⅱ scores and total bilirubin level were significantly higher in patients acquired enterococcal infection than in those infected with other pathogenic microorganisms. Conclusions High APACHE Ⅱ score, high total bilirubin level, low platelet count and length of use of broad-spectrum antibiotics before OLT were closely associated with nosocomial infection. As an important indicator, change in total bilirubin level not only represented the liver function ,but also was one of the high risk factors to nosocomial infection in patients undergoing OLT.

Objective Post-operative hypoxemia occurred frequently after extubation in patients who underwent orthotopic liver transplantation (OLT) in ICU. This study is to investigate the efficiency of hyperoxia solution in improving oxygenation. Methods Ten OLT cases, who post-operatively manifested hypoxemia after extubation, were enrolled in this study. Hyperoxia Ringer's solution (500ml) prepared by Jing-Shu-Yang (an apparatus of oxygen supply, Vanform Co., Shandong) was infused at a rate of 200ml/hr. Hemodynamic parameters, blood gas, and blood lactate were determined at the beginning, end of infusion, and 1 hour after the infusion, with recording of the following data: heart rate (HR), mean arterial pressure (MAP), pulmonary arterial pressure (PAP), and pulmonary capillaries wedged pressure (PCWP). Results Compared with the levels at the beginning of infusion, SpO2 and SvO2 increased significantly at the end of the infusion of 500 ml hyperoxia Ringer's solution, and they returned to the baselines 1 hour later, although regular Ringer′s solution was coutinuously given by the same infusion rate. HR, MAP and PCWP were kept stable with the solution infusion. Notably, PAP was decreased markedly at the end of infusion, and blood lactate level remained unchanged after the intervention. Conclusion Hyperoxia Ringer's solution infusion improved oxygenation in OLT patients who suffered from acute lung injury with hypoxemia postoperatively. PAP decreased markedly as hypoxemia was corrected.

Objective To observe the formation process with 3.0 T MRI dynamically, and to discuss the feasibility of molecular imaging studies on restenosis. Methods The models were built with balloon (2.0 F) injury which were separated into restenosis group (n=48) and control group (n=48). Zero h, 24 h, 1 week, 2 week, 4 week and 8 week after surgery, 3.0 T MRI scanning (T1WI, T2WI, PDWI) was performed respectively, the vascular of injured side were obtained for HE staining to observe the pathological changes, to analyze the measurement of neointimal area (IA), intimal proliferation index (IHI), lumen area (LA) and stenosis rates, correlation between HE staining measurements and MR images were analyzed. Two weeks after the injury, the restenosis model of rats (n=8) and control rats (n=8) were injected ultrasmall superparamagntiec iron oxide (USPIO,1 mmol/kg) by tail vein, respectively. 3.0 T MRI scanning (T2WI) was underwent at 0 h and 24 h after injection, the change of the arterial wall T2 signal was quantitatively analyzed and the relative signal intensity (rSI) and relative change rate (rSIC) of the vessel wall were calculated. Reference to MRI images, corresponding line segments were taken for Perl's blue staining and immunohistochemically staining of macrophages. One-way ANOVA, Pearson and t test were used for statistical analysis. Results In the early?term (0 h,24 h), the wall and surrounding high signal organization boundary was not clear, there was no obvious morphological change of the lumen. In the medium?term (1, 2 week), signal of the injured wall increased with different extents, wall thickening and luminal narrowing was progressive, the inwall was coarse. In the later?term (4, 8 week) wall signal got slightly lower, wall thickness, lumen change were not significant, the wall area and LA were significantly associated with pathologic measurement result (r value were 0.978, 0.732; P<0.05). In the control group, signal of wall and lumen morphological change were not significant among the different time points. IA were (0.131 ± 0.011) mm2, (0.588 ± 0.017) mm2, (1.061 ± 0.033) mm2, (1.192 ± 0.034) mm2;1, 2, 4, 8 week after injury, respectively, IHI were 0.235 ± 0.022, 0.578 ± 0.013, 0.715 ± 0.011, 0.737 ± 0.009, respectively, stenosis rates were (5.586 ± 0.987)%, (25.395 ± 1.112)%, (40.019 ± 1.298)%, (41.890 ± 0.951)%, respectively, difference between groups were statistically (P<0.05). In the control group, there was no significant differences of medium area, luminal stenosis and neointimal formation respectively at different time points (P>0.05). rSI was 1.582±0.051 after the injection of USPIO, then 24 h after injection of USPIO, T2 signal of the vessel wall was reduced significantly, rSI was 1.260 ± 0.088, rSIC was (-20.249 ± 6.489) % with statistical difference (t value was 8.924,P<0.05). But there was no statistical difference in control rats (P>0.05). Perl's staining combined with immunohistochemical staining confirmed that the iron particles were taken by the macrophage's phagocytosis just in the neointimal. Conclusion 3.0 T MRI is capable of demonstrating the vessel wall and lumen changes dynamically, and the measurements are correlated with pathological results. USPIO can be consumed by macrophages in the neointimal, resulting in T2 signal of the vessel wall decreased significantly.
