限制性液体复苏对肝脏缺血-再灌注损伤的影响

Objective To investigate the effects of limited resuscitation on hepatic ischernia-reperfusion in-jury in rots with hemorrhagic shock. Method Uncontrolled hemorrhagic shock was induced in 54 rats by transect-ing the middle branch of the splenic artery to produce standardized massive splenic injury. Resuscitation started when the mean arterial pressure (MAP) reached 40 mmHg. The rats were randomly divided (n = 9per group) in-to sham-operated group (SS), or one of five treatment groups in which infusion of Ringer' s solution was continually administrated to maintain MAP at 40 (RS40), 50 (RS50), 60 (RS60), 80 (RS80) or 100 mmHg (RS100) for 45 minutes (T45 point). After the bleeding was controlled, resuscitation was continued with Ringer's solution and whole blood (2:1) to increase the MAP to 100 mmHg for 120 minutes (T165 point), which was followed by obser-vation for 240 minutes (T405 point). All animals were observed for 240 minutes or until death. Blood specimens were collected at TO, T45, T165 and T405 for determination of blood lactate levels. At the end of the experiment,a small amount of hepatic tissue was collected to measure tissue blood perfusion, total antioxidative capacity (TAOC), Na+K+ ATPase activity and malondialdehyde (MDA) levels. Results At T405, the blood lactate lev-els in the RS80 and RS100 groups [(3.60±0.68) and (3.84 ± 1.09) mmol/L, respectively] were significantly higher than those in the SS, RS40, RS50 and RS60 groups [(2.00±0.66),(2.74±1.45),(2.43 +0.94) and (2.07±0.95) mmol/L, respectively;all:P < 0.05]. The MDA levels were significantly higher in the RS80 and RS100[(7.32±0.31) and (7.71±0.23) nmol/mg,respectively] than those in the SS, RS40, RS50 and RS60 groups[(4.95±0.80),(6.14±0.94),(6.42±0.48) and (6.84±0.36) nmol/mg, respeetively;all: P <0.05]. The Na+ K+ ATPase and TAOC levels were significantly lower in all of the RS groups than those in the SS group (all: P < 0.05), and those in the RS80 and RS100 groups was significantly lower than those in the RS40,RS50 and RS60 groups (all: P <0.05). Blood perfusion in the RS80 and RS100 groups was significantly lower than that in the other groups (all: P < 0.05). Conclusions If hemorrhage is uncontrolled, limited resuscitation appears to balance the needs for organ perfusion, improve the microcircttlation and decrease lactate levels. Fur-thermore, limited resuscitation could decrease ischemia-reperfusion injury in liver tissue.     

超声、CA125对卵巢恶性肿瘤的诊断与术后随访

目的研究超声和CA125在检查卵巢恶性肿瘤中的应用价值。，方法取术后病理确诊的卵巢恶性肿瘤69例，并以48例良性肿瘤为对照组，两组病例术前均行超声检查和CA125测定。结果超声检查与CA125测定术前对卵巢恶性肿瘤诊断的敏感性分别为88％、84％，特异性分别为87．0％、97．9％、准确性分别为88．0％、89．7％。超声及CA125联合诊断恶性卵巢肿瘤的敏感性为97．1％，特异性为97．9％，准确性为97．4％。对恶性肿瘤的随访结果显示：CA125测定值随化疗次数的增加而下降，测定值的高低、持续时间与肿瘤的复发和转移密切相关。结论超声检查结合CA125测定对鉴别卵巢良恶性肿瘤有重要价值，可提高术前确诊率。术后随访及预测肿瘤的复发和转移，CA125较超声更敏感。
