| 1 | Pre-and postoperative systemic hemodynamic evaluation in patients subjected to esophagogastric devascularization plus splenectomy and distal splenorenal shunt:A comparative study in schistomomal portal hypertension显示文摘AIM: To investigate the systemic hemodynamic effects of two surgical procedures largely employed for treatment of schistosomal portal hypertension. METHODS: Thirty-six patients undergoing elective surgical treatment of portal hypertension due to hepatosplenic mansonic schistosomiasis were prospectively evaluated. All patients were subjected to preoperative pulmonary artery catheterization; 17 were submitted to esophagogastric devascularization and splenectomy (EGDS) and 19 to distal splenorenal shunt (DSRS). The systemic hemodynamic assessment was repeated 4 d after the surgical procedure. RESULTS: Preoperative evaluation revealed (mean ± SD) an increased cardiac index (4.78 ± 1.13 L/min per m2),associated with a reduction in systemic vascular resistance index (1457 ± 380.7 dynes.s/cm5.m2). The mean pulmonary artery pressure (18 ± 5.1 mmHg) as well as the right atrial pressure (7.9 ± 2.5 mmHg) were increased,while the pulmonary vascular resistance index (133 ± 62 dynes.s/cm5.m2) was decreased. Four days after EGDS,a significant reduction in cardiac index (3.80 ± 0.4 L/min per m2,P < 0.001) and increase in systemic vascular resistance index (1901.4 ± 330.2 dynes.s/cm5. m2,P < 0.001) toward normal levels were observed. There was also a significant reduction in pulmonary artery pressure (12.65 ± 4.7 mmHg,P < 0.001) and no significant changes in the pulmonary vascular resistance index (141.6 ± 102.9 dynes.s/cm5.m2). Four days after DSRS,a non-significant increase in cardiac index (5.2 ± 0.76 L/min per m2) and systemic vascular resistance index (1389 ± 311 dynes.s/cm5.m2) was observed. There was also a non-significant increase in pulmonary artery pressure (19.84 ± 5.2 mmHg),right cardiac work index (1.38 ± 0.4 kg.m/m2) and right ventricular systolic work index (16.3 ± 6.3 g.m/m2),without significant changes in the pulmonary vascular resistance index (139.7 ± 67.8 dynes.s/cm5.m2). CONCLUSION: The hyperdynamic circulatory state observed in mansonic schistosomiasis was corrected by EGDS,but was maintained in patients who underwent DSRS. Similarly,the elevated mean pulmonary artery pressure was corrected after EGDS and maintained after DSRS. EGDS seems to be the most physiologic surgery for patients with schistosomal portal hypertension. | Roberto de Cleva Paulo Herman Luis Augusto Carneiro D’albuquerque Vincenzo Pugliese Orlando Luis Santarem William Abro Saad | 2007 | World Journal of Gastroenterology2007，13，41： | 9 |
| 2 | Characterisation and seasonal variations of particles in the atmosphere of rural, urban and industrial areas:Organic compounds显示文摘Atmospheric aerosol samples(PM_(2.5–0.3), i.e., atmospheric particles ranging from 0.3 to2.5 μm) were collected during two periods: spring–summer 2008 and autumn–winter 2008–2009, using high volume samplers equipped with cascade impactors. Two sites located in the Northern France were compared in this study: a highly industrialised city(Dunkirk) and a rural site(Rubrouck). Physicochemical analysis of particulate matter(PM) was undertaken to propose parameters that could be used to distinguish the various sources and to exhibit seasonal variations but also to provide knowledge of chemical element composition for the interpretation of future toxicological studies. The study showed that PM2.5–0.3concentration in the atmosphere of the rural area remains stable along the year and was significantly lower than in the urban or industrial ones, for which concentrations increase during winter.High concentrations of polycyclic aromatic hydrocarbons(PAHs), dioxins, furans and dioxin like polychlorinated biphenyls(DL-PCBs), generated by industrial activities, traffic and municipal wastes incineration were detected in the samples. Specific criteria like Carbon Preference Index(CPI) and Combustion PAHs/Total PAHs ratio(CPAHs/TPAHs) were used to identify the possible sources of atmospheric pollution. They revealed that paraffins are mainly emitted by biogenic sources in spring–summer whereas as in the case of PAHs, they have numerous anthropogenic emission sources in autumn-winter(mainly from traffic and domestic heating). | Fabrice Cazier Paul Genevray Dorothée Dewaele Habiba Nouali Anthony Verdin Frédéric Ledoux Adam Hachimi Lucie Courcot Sylvain Billet Saad Bouhsina Pirouz Shirali Guillaume Garcon Dominique Courcot | 2016 | Journal of Environmental Sciences2016，28，6： | 4 |
