目的评价氟比洛芬酯注射液用于腹部手术术后镇痛的安全性和有效性。方法将45例行开腹胆囊切除术的患者随机分成3组,A组注射氟比洛芬酯注射液,B组按需求肌注度冷丁2mg/kg,C组采用硬膜外患者自控镇痛。术后2、4、12、24h进行模糊视觉疼痛评分(VAS)法评分,监测患者的心率、呼吸、血压及脉搏氧饱和度,并记录副反应。结果A组无1例加用度冷丁,A组和C组术后2、12和24h的VAS分值均明显低于B组(p<0.05)。3组恶心呕吐的发生率无显著性差异(p>0.05)。结论氟比洛芬酯注射液用于腹部手术术后镇痛,持续、有效、经济,使用方便,不良反应少。     

终末期肝病模型评分在原发性肝癌合并肝硬化脾功能亢进外科治疗中的作用

目的 探讨终末期肝病模型(MELD)评分评估肝储备功能在原发性肝癌合并肝硬化脾功能亢进中确定手术适应证的应用价值.方法 对2001年1月至2007年1月间行肝癌切除联合脾切除(联合术)治疗的40例原发性肝癌合并肝硬化脾功能亢进患者的临床资料进行回顾性分析.通过MELD评分与Child-Pugh分级比较,结合临床资料及术后并发症分析,确定这一方法在评估肝储备功能中的作用.结果 同一Child-Pugh分级的患者MELD评分结果并不一致,在各级别间有交错现象.术后发生肝功能衰竭组(6例)的MELD评分均值为(24.6±6.6).未发生肝功能衰竭组(34例)的MELD评分均值为(16.3±8.5),差异有统计学意义(P<0.05).根据MELD评分分为A组16例(MELD评分<10),B组17例(MELD评分10-20),C组7例(MELD评分>20).A组术后肝功能衰竭发生率为0,B组为11.8%(2/17),C组为57.1%(4/7),差异有统计学意义(P<0.05).根据Child-Pugh分级分为Ⅰ级26例,Ⅱ级14例.Ⅰ级术后肝功能衰竭发生率为15.4%(4/26),Ⅱ级为14.3%(2/14),差异无统计学意义(P>0.05).结论 MELD评分能够较为客观地反映肝储备功能,对外科术式的选择、手术时机的确定有一定的参考作用.     

体外不同比例再生肝细胞与结肠癌细胞的共培养

Objective To investigate the proliferation potential of colon cancer cells co-cultured with different proportions regenerating hepatocytes and role of the cell growth factors related to liver regeneration in vitro.Methods Active regenerating hepatocytes were obtained by collagenase perfusion in situ of rats models underwent 70% liver resection after 24 hours.Co-cultures with different proportions of hepatocytes to human colon cell line SW480 were performed respectively.The proportion of hepatocytes to human colon cell line SW480 Was 10:1 in group A,1:1 in group B.There was only human colon cell line SW480 in group C(control group).Proliferation capacity was assessed with the percentage by 3H-thy incorporation.Concentration of epidermal growth factor(EGF),insulin-like growth factor-1(IGF-1)and hepatocyte growth factor(HGF)was analyzed by ELISA.Results There was no significant difference among the 3 groups in 3H-thy incorporation percentage,and concentration of EGF,IGF-land HGF after 24 hours' culture(P>0.05).3H-thy incorporation percentage(15.9±1.4,13.2±1.5),and concerntration of EGF [(722.9±55.4)ng/L,(498.2+41.5)ng/L]and IGF-1[(755.2±35.7)ng/L,(538.1±37.5)ng/L]in Group A and B were higher than that in group C after 72 hours(P<0.05).Especially the indexes above in group A were higher than that in group B(P<0.05).there was no significant difference in concerntration of HGF among the 3 groups after 72 hours(P>O.05).Conclusions These results imply that the regenerating hepatocytes contribute to the hyperproliferative state of co-culturing colon cancer cells.The mechanism maybe have relationship with EGF and IGF-1 high expression in colon cancer cells caused by growth signals coming from hepatocytes.
