背驮式肝移植的技术改进(附一例报告)

目的 探讨更完善的背驮式肝移植术式。方法 保留受者的腔静脉、肝静脉全部结扎,在受者的下腔静脉上开一侧孔,将供肝腔静脉近端与受者的下腔静脉侧孔行端侧吻合,远端缝扎。术中测定受者各时相的血流动力学参数。结果 无肝期为５０例,整个手术历时８小时,术中失血２５００ｍｌ。术中血流动力学平稳。术后肝功能指标大部分恢复正常,胆汁引流量约２００ｍｌ／ｄ。术后第５８天因肾功能衰竭死亡。结论 本术式适合于良性终末期肝     

活血通腑方对大鼠术后腹腔粘连的实验研究

目的:观察活血通腑方对大鼠术后血浆纤维蛋白原(fibrinogen,FIB)及纤维蛋白降解产物(fibrin protein decompound production,FDP)含量的影响,探讨其防治腹腔粘连机制.方法:120只SD雄性大鼠随机分为治疗组、阳性对照组、模型组、假手术组4组,每组30只.分别进行胃内药物灌注,测定1、3、5、7、21 d的血FIB、FDP含量,观察腹腔粘连情况并进行比较.结果:活血通腑方组降低术后血FIB含量,5、7、21 d(P＜0.01);升高术后血FDP含量,3、5、7 d(P＜0.01);降低腹腔粘连级别评分(P＜0.01).结论:活血通腑方能使大鼠术后血FIB降低、FDP升高,防治粘连.     

Annexin A4在结直肠癌中的表达及意义

目的 研究Annexin A4在结直肠癌组织中的表达及意义,以探讨结直肠癌的发生机制.方法 采用Western blot的方法对正常结直肠组织以及Dukes A、B、C、D期结直肠癌组织进行Annexin A4及其磷酸化检测.结果 在正常组织及结直肠癌组织中Annexin A4和其磷酸化均有表达,Annexin A4在...     

直视观察按压耳穴对胆囊压力影响及特异性初探

对胆石组及非胆石组各50例,在外科手术直视下对比观察刺激耳胰胆穴前后胆压改变,结果表明:胆囊有功能病例对排石可能有一定作用;胆囊无功能病例对排石无作用,但能缓解临床症状。故在应用按压耳穴法治疗胆石症时,应注意了解胆囊的功能、结石的大小及有无梗阻等,此乃取得排石疗效的关键。同时表明在胰胆穴区“以痛为输”,对诊断胆系疾病有一定的特异性。     

Clinical Study on General lmmunotherapy of Hepatocellular Carcinoma

In the present study,67 cases of hepatocellular carcinoma(HCC)were treated withimmunotherapy or immunochernotherapy.The results indicated that natural killer cell(NK)andantibody-dependent cytotoxicity cell(ADCC)activities and lymphocyte transformation rate(LTR)were significantly improved in vivo after treatment.The NK activity in tumor tissue,which showed aheavy immunosuppression,could also be enhanced and recovered to normal level after treatment withlymphokine mixture and 5-fluorouracil(5-FU).Immunity of host with postoperativeimmunochemotherapy was rapidly improved and recovery vate was high.The survival time in thesecases of unresectable tumors was obviously prolonged when a general immunotherapy was used.Immunochemotherapy can impr(?)ve immunity and inhibit selectively Ts cells as well as kill directly thetremor cells;therefore,it can play an important role in the treatment of hepatocellular carcinomaand in the prevention of its recurrence after operation.     

肝泡状棘球蚴病52例临床治疗经验

本文报道由于多房棘球绦虫所致的肝泡状棘球蚴病52例:男35例,女17例,年龄14～52岁,多来自牧区。主要体征为上腹部包块,有黄疸者12例,免疫试验均显阳性,辅助检查如B超、同位素扫描、PTC等提示肝内占位性病变,X片显示特殊钙化点。病例均经手术及病理证实。根治手术5例,术后预后好,8～21年随访无复发。姑息性手术7例亦获改善症状等疗效。13例经长达1～16个月的甲苯咪唑化疗无明显副作用,病情改善,包块缩小,药物剂量较大,疗程较长,治疗效果较好。本文就诊断和治疗方面作简要讨论。     

Mechanism of change in cardiac function after mitral valve replacement

Left ventricular contractility was measured using Doppler echocardiography in 37 pa-tients with rheumatic mitral valve disease.Myocardial pathological lesions were studied quanti-tatively by means of the image analysis system and light microscopic examination.The resultsshowed that attenuated cardiac function is due to pathological change of the mitral valve andpathological lesions of the left ventrieular myocardium including increased interstitial fibrosis,thickened intramyocardial arterial wall leading to concentric narrowing of the lumen,hyper-trophic myocardial fiber and endocardial proliferation.Since mitral valve replacement can notcorrect the irreversible myocardial pathological lesions,perioperative protection of the my-ocardium should be emphasized,and intraoperative injury to the myocardium should be mini-mized as far as possible.     

中西医结合微创治疗粘连性肠梗阻

目的：探索中西医结合与微创技术联合治疗粘连性肠梗阻的疗效。方法：31例粘连性肠梗阻，在急性期以中西医结合疗法辨证施治，解除急性梗阻；梗阻缓解后行腹腔镜粘连松解术，预防梗阻复发。结果：急性期经中西医结合治疗，肠梗阻均解除。缓解期行腹腔镜粘连松解术，成功26例（83．9％）；中转开腹手术5例（16．1％）。腹腔镜粘连松解术后胃肠功能恢复时间0．5－2d；术后住院时间2－4d。26例腹腔镜粘连松解术后随访（3个月－3年），均无肠梗阻复发的表现。结论：中西医结合微创治疗粘连性肠梗阻中转开腹率较低，并发症发生率低，术后效果好，无梗阻再发。
