提肛散敷脐结合盆底重建联合吻合器痔上黏膜环切术治疗直肠脱垂的临床观察

目的观察盆底重建联合吻合器痔上黏膜环切术结合提肛散敷脐治疗直肠脱垂的临床疗效。方法选取直肠脱垂患者80例,随机分为观察组及对照组,2组患者均采用盆底重建联合吻合器痔上黏膜环切术进行治疗,观察组患者于入院第2天即给予提肛散敷脐治疗,持续用药2周;观察2组患者手术前后疼痛、肛门坠胀感及排便评分,并对比直肠脱出长度、肛管静息压、最大收缩压及舒张压改善程度。结果观察组术后1周时疼痛评分明显低于对照组(P <0. 05);观察组术后1个月直肠脱出长度明显低于对照组(P <0. 05),排便、肛门坠胀、肛门梗阻评分均明显低于对照组(P均<0. 05);观察组术后肛管静息压、最大收缩压及舒张压改善程度均明显优于对照组(P均<0. 05)。结论盆底重建联合吻合器痔上黏膜环切术结合提肛散敷脐治疗直肠脱垂,可显著改善患者临床症状,缓解术后疼痛,疗效确切。

矩形斜齿打板式螺旋推进器

玉米脱皮破糁机的螺旋推进器尚存在一定的缺陷,新设计的矩形斜齿打板式螺旋推进器,在结构上较原有的推进器做了较好的改进,使推进器工作面的作用得到了充分地发挥,既提高了硬度和耐磨性,同时也提高了玉米脱皮破糁机的脱皮破糁效率,增强了后续工序的提脐效果。

Anti-angiogenic effects of the water extract of HangAmDan(WEHAD),a Korean traditional medicine

We investigated the anti-angiogenic effects of the water extract of HangAmDan (WEHAD),which is a crude extract of nine Korean medicinal substances of animal and plant origin.In human umbilical vein endothelial cells,WEHAD significantly inhibited bFGF-induced proliferation,adhesion,migration,and capillary tube formation.We used an antibody array to perform an analysis of signaling proteins,which showed up-regulated expression of various proteins including RAD51,RAD52,and p73,and down-regulated expression of pFAK.Blood vessel formation in a chick chorioallantoic membrane (CAM) treated with WEHAD was markedly reduced in length compared with a PBS-treated control group.These results suggest that inhibition of angiogenesis by WEHAD may be the mechanism of action for the anti-cancer effects of HAD.
