门静脉高压症是慢性肝病的主要合并症之一,它所导致的食管胃底静脉曲张破裂出血死亡率可达30%~50%,是肝硬变患者的主要死亡原因。1概述自1945年Whipple等人倡导门体分流手术治疗门静脉高压症以来,各国学者作出了不懈努力,探求对这种顽症的治疗手段。最近20~30年在治疗方法上出现了许多革新,如内窥镜下曲张静脉硬化剂注射、曲张静脉套扎、门体静脉选择性分流(远端脾肾分流)等。应用β受体阻滞剂心得安来预防或治疗门静脉高压症引起的上消化道出血取得了肯定的疗效。小口径人工血管门静脉下腔静脉搭桥分流减少了门体分流手术后脑病的发生率,而复发出血率几乎可与传统门腔分流术相比。经颈内静脉肝内门体分流术(TIPSS)治疗急性上消化道出血的疗效十分肯定,尤其适用于手术风险大、肝功能差者。肝脏移植作为治疗终末期不可逆性肝病的成熟手段,近年来也越来越多地应用于肝硬变门静脉高压症的治疗,与其它各种治疗手段相比,肝移植可算是对门静脉高压症治疗的一种革命性的变化,一个成功的肝移植一劳永逸地解决了门静脉高压症产生的根源,使门静脉高压症得到根治。
To quantitatively measure the α1-adrenergic receptors and select the suitable conditions of receptor-ligand binding assay. Radioligand binding analysis was used to measure the concentration of α1-adrenergic receptors, and the measuring conditions were selected, respectively. Under the selected conditions, the α1-adrenergic receptors in lier plasma membranes of 8 nonhepatopathy subjects were measured.Under such suitable conditions as 3H-prazosin concentration 0.1-2.0nmol/L, incubating temperature 37℃, reaction time 20 minutes and seperating free ligand from system with double layer of filter paper, the binding of 3H-prazosin to α1receptors from 8 nonhepatopathy subjects were saturable with a high affinity. The Bmax, Kd, RMC and Hill coefficient were 142.1±14.1 fmol per milligram of protein, 0.2382±0.0548 nM, 739.0±167.6 fmol per gram of liver and 0.90±0.03, respectively.The suitable conditions may be very important for measuring α1-adrenergic receptors in human liver plasma membranes, which should be considered in hepatopathy studies.
【 Abstract 】 Objective To investigate the precautionary effect of fibrin glue on postoperative bleeding and bile leakage when used in partial hepatic resection. Methods House-hold rabbit partial hepatectomy model was prepared and 40 rabbits were divided into sham operation ( SO) group (n=10), control group (n=10) and protocol group (n=20) randomly. The SO rabbits received laparotomy only, while both the control and protocol group received partial hepatectomy. Fibrin glue was used in the protocol group following electric coagulation therapy while the control group received electric coagulation therapy only. The animals’ diet, weight and adverse effects were observed then, and the celiac drainage volume, levels of hemoglobin (Hg), WBC and TBil in celiac outflow and ALT, AST, LDH and TBil in rabbit serum were checked on schedule after operation. Results The average blood loss volume and operation time in the protocol group were (16.0±2.7) ml and (23.7±2.9) min respectively, which were lower than those in the control group 〔 (20.8 ± 3.5) ml and (27.3 ± 2.9) min (P < 0.01) 〕 . The celiac drainage volume, levels of Hg, WBC and TBil in celiac outflow decreased gradually on postoperative days in protocol groups (P < 0.05). The levels of Hg in celiac outflow of the protocol group on the 1st, 2nd and 7th postoperative day were lower than those of the control group (P < 0.05), and the result of TBil was the same on the 1st, 2nd, 3rd, 5th and 7th postoperative day (P < 0.05). The serum ALT, AST, LDH and TBil levels in the control and protocol groups were higher than those in the SO group significantly (P < 0.01), while the serum ALT, AST (except on the 3rd postoperative day) and LDH levels in the protocol group were lower than those in the control group (P < 0.05) in significance.All animals had good appetite, normal weight gain and no adverse reaction and death occurred. Conclusion Application of fibrin glue may effectively prevent and cure the postoperative bleeding and bile leakage in partial hepatectomy without any adverse reaction.
ObjectiveTo evaluate long-term therapeutic effect of esophagogastric devascularization without splenectomy in treatment of portal hypertension with esophagogastric varices hemorrhage. MethodsThe patients who took esophagogastric devascularization without splenectomy from 2008 to 2013 were followed-up in clinic or through phone. The remission of esophagogastric varices, rebleeding, survival and long-term postoperative complications were observed. ResultsA total of 32 patients were taken esophagogastric devascularization without splenectomy in Peking University People's Hospital from 2008 to 2013. One patient died during the perioperative period. Twenty-three patients were followed-up for 10-81 months with an average 45.5 months, of whom 7 patients had rebleeding, 5 patients died, 3 patients had new onset portal vein thrombosis, 2 patients had esophageal anastomotic strictures. ConclusionEsophagogastric devascularization without splenectomy is an effective method in treatment of portal hypertension with esophagogastric varices hemorrhage in selected patients.
Objective To evaluate the therapeutic effect of selective paraesophagogastric devascularization withoutsplenectomy in treatment of portal hypertension with upper gastrointestinal hemorrhage. Methods The clinical data of 27 patients who received selective paraesophagogastric devascularization without splenectomy from 2008 to 2011 were retrospectively analyzed. The hemogram, hepatic function, perioperative compliations, and free portal pressure (FPP) were observed. The patients were followed-up and the re-bleeding rate and survival rate were observed. Results The FPP decreased significantly(P<0.05) after operation. The complication rate was 33.3%(9/27) after operation, including2 cases(7.4%) stress ulcer bleeding, 1 case (3.7%) acute bleeding portal hypertensive gastropathy, 1 case (3.7%) deep venous thrombosis, 1 case (3.7%) acute lung injury, 1 case (3.7%) death of hepatic encephalopathy, 3 cases(11.1%) new onset portal vein thrombosis. Twenty-four patients were followed up for an average of 27 months (8-57 months). The overal survival rate was 92.6% (25/27). Conclusion Selective paraesophagogastric devascularization without splenectomy is an effective method for treatment of portal hypertension with upper gastrointestinal hemorrhage.
Objective To study the value of the clinical application of stereography and measurement of liver volume in cirrhotic patients with portal hypertension. Methods By use of the personal computer and the software of threedimensional reconstruction and measurement system of liver faultage photograph, the liver volume in vivo was successfully measured and the threedimensional image of the liver rebuilt in 46 posthepatitic cirrhotics who were selected for orthotopic liver transplantation and in 30 noncirrhotic controls, and comparison with the reference volume of recipient liver was obtained by means of water deplacement after transplantation. Results The liver volume of cirrhotic patients with portal hypertension measured by software and water deplacement was (983.33±206.11) cm3, and (904.93±209.56) cm3 respectively. Comparison by means of linear regression analysis between volume measurement on threedimensional reconstruction software and reference volume showed a nearly ideal correlation coefficient(r=0.969,P<0.01), the average error was 8.66%.The average of liver volume in controls was (1287.00±96.18) cm3, and was positively correlated to the height,weight and body surface area (r=0.845,0.833,0.932 respectively,P<0.01),and was different from that of cirrhotics. Liver volume of cirrhoitic patients with portal hypertension was related to their ChildPugh classification. The liver volume of patients in Child C group was significantly smaller than that of patients of Child B group, and was significantly correlated with Alb (r=0.496, P<0.01) and TBIL(r=-0.493, P<0.01),PT(r=-0.517, P<0.01), but was not significantly correlated with ALT(r=0.206,Pgt;0.05),portal pressure(r=-0.093,P=0.539) and portosystemic shunt index (r=0.044,P=0.769). Conclusion The volume measurement of the liver by the threedimensional software is relatively accurate. Liver volume of cirrhotic patients with portal hypertension was significantly related to their liver function,and can reflect the liver reserve function.
【Abstract】Objective To investigate the expression of the mRNA of cancer-testis antigen 9 (CT9) gene in hepatocellular carcinoma. Methods The expression of CT9 mRNA was detected through RT-PCR in HCC tissues and their adjacent non-HCC tissues from 45 HCC patients. From CT9 RT-PCR positive products, 3 samples were selected randomly and were sequenced. ResultsCT9 mRNA was detectable in 51.1%(23/45) of HCC samples, and no expression of CT9 mRNA was detected in the adjacent non-HCC tissues. In addition, the RTPCR products were proved to be CT9 cDNA by DNA sequencing. No relationship was found between the expression of CT9 mRNA and clinical factors such as age, sex, tumor size, degree of tumor differentiation, serum αfetoprotein level and infection of hepatitis B virus or hepatitis C virus (Pgt;0.05). ConclusionCT9 mRNA is expressed with high percentage and specificity in hepatocellular carcinomas. The CT9 gene product is a potential target for antigenspecific immunotherapy of HCC.
