【 Abstract 】 Objective To explore the effect of gamma-globulin in evaluating hepatic functional reservation in patients with liver tumor. Methods Serum protein electrophoresis (SPE) was performed on 30 patients with liver tumor to get gamma-globulin and preoperative Child-Pugh classification. Then the relations between gamma-globulin and preoperative and postoperative Child-Pugh classification were studied. While with gamma-globulin as evaluating standard, the validity compared with Child-Pugh classification were studied. Results The gamma-globulin was lower in classification A patients 〔（ 21.053 3 ± 6.001 4)% 〕 than that in classification B 〔 (28.800 0 ± 8.672 5)% 〕 before operation. While the gamma-globulin 〔 (21.022 0 ± 5.354 6)% 〕 of classification A patients after operation was also lower than that of classification B/C 〔 (29.556 0 ± 7.698 5)% 〕 . These differences were significant (P ＜ 0.05). With gamma-globulin gt;30% as evaluating standard ， the sensitivity and specificity were 80.00% and 96.00%, respectively. Conclusion Gamma-globulin can reflect hepatic functional reservation in patients with liver tumor. Combining gamma-globulin and Child-Pugh classification can evaluate hepatic functional reservation more objectively.
ObjectiveTo investigate impact of splenectomy plus pericardial devascularization on liver hemodynamics and liver function for liver cirrhosis patients with portal hypertension. MethodsThe internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of portal vein and hepatic artery of 42 cases of liver cirrhosis with portal hypertension were measured by Doppler ultrasonic instrument on day 1 before operation and on day 7 after operation. The free portal pressures at different phases (after open abdomen, after splenic artery ligation, after splenectomy, and after devasculanrization) were read from the disposable pressure sensor. Twenty-four healthy people through physical examination were selected as control. Results① The free portal pressure of liver cirrhosis patients with portal hypertension was decreased from (29.12±1.40) mm Hg after open abdomen to (22.71±1.21) mm Hg after splenic artery ligation, and further decreased to (21.32±1.12) mm Hg after splenectomy, but increased to (22.42±1.15) mm Hg after devasculanrization, the difference was statisticly different (all P < 0.01). ② Compared with the healthy people, for the liver cirrhosis patients with portal hypertension, the internal diameter, maximum velocity, minimum velocity, and flow volume of portal vein were significantly enlarged (all P < 0.01), which of hepatic artery were significantly reduced (all P < 0.01) on day 1 before operation; On day 7 after operation, the internal diameter of portal vein was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, and mean velocity of portal vein were significantly enlarged (all P < 0.01), but the internal diameter of hepatic artery was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01). For the liver cirrhosis patients with portal hypertension, compared with the values on day 1 before operation, the internal diameter and the flow volume of portal vein were significantly reduced (all P < 0.01) on day 7 after operation; the internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01) on day 7 after operation. ③ The Child-Pugh classification of liver function between before and after surgery had no significant difference (χ2=1.050, P > 0.05). ④ No death and no hepatic encephalopathy occurred, no thrombosis of splenic vein or portal vein was observed on day 7 after surgery. Conclusionsplenectomy plus pericardial devascularization could decrease portal vein pressure and reduce blood flow of portal vein, while increase blood flow of hepatic artery, it doesn't affect liver function.
Objective To investigate whether protease inhibitor (ulinastatin, UTI) can protect liver from ischemiareperfusion injury in hepatocellular carcinoma (HCC) patients undergoing hepatectomy after hepatic inflow occlusion. Methods A prospective randomized control study was designed. Thirtyone HCC patients undergoing hepatectomy after hepatic inflow blood occlusion were randomly divided into the following two groups. UTI group (n=16)， 1×105 units of ulinastatin was given intravenously in operation, then the dosage was continuously used twice a day up to 5 days postoperatively. Control group (n=15), the patients received other liver protective drugs. Liver function, plasma C-reactive protein (CRP) and cortisol level were compared between these two groups. Results The postoperative liver function of the UTI group was significantly improved compared with the control group. For example, on the third postoperative day the aspartate transaminase (AST), alanine transaminase (ALT) and total bilirubin level in the UTI group were significantly lower than those in the control group, respectively (P＜0.05). On the first postoperative day, the plasma CRP concentration in the UTI group was significantly lower than that in the control group(P＜0.01). The plasma cortisol level in the control group markedly increased compared with the level before operation(P=0.046). However, there was no significant difference in the UTI group between before and after operation. Conclusion Ulinastatin can effectively protect liver from ischemia/reperfusion injury in HCC patients undergoing hepatectomy performed after hepatic inflow occlusion. Also, it can relieve the surgical stress for patients.
Objective To discuss the relationship between the efficiency of bile duct drainage and the postoperative liver functional recovery and the prognosis of hilar cholangiocarcinoma. Methods We studied retrospectively 58 cases of hilar cholangiocarcinoma which entered our department between June 1987 and October 1998. The postoperative liver functional recovery and mortality and morbidity between unilateral (n＝27) and bilateral (n＝31) bile duct drainage groups were compared. Results The liver function in bilateral drainage group was nearly normal within 6 weeks after operation. The ALb level of unilateral drainaged patients recovered gradually to normal after operation, and the TBIL and ALT decrease nearly to the normal range within 6 weeks after operation. The AKP decreased within 2 postoperative weeks, then steadily increased. The differences of perioperative complication rate and mortality of the two groups showed no significance. Conclusion The data showed that the liver function can recover to some extent by unilateral bile duct drainage, and unilateral drainage operations are the choice for hilar cholangiocarcinoma that can not be excised now.
Objective To study the effect of recombinant growth hormone (rhGH) on improvement of liver function and liver regeneration in animal and patients after hepatectomy. Methods The liver cirrhosis model of SD species mouse was set up, then the mouse were randomly divided into experiment group and control group, then 30%-40% liver of all the models were resected, rhGH was used by hypodermic injection (0.2-0.4ml/100g) in experimental group, and the equal dose of N.S. were given in control group every day. Then liver function, arterial blood ketone body ratio(AKBR), and the regenerated liver/body weight ratio (RL/W) were determined, histopathology of the cirrhosis with microscope and electron microscope and the mitotic index (MI) of liver cell on 7, 14 and 28th day after operation were observed. Clinically,39 hepatectomized patients were randomly divided into experiment group and control group, liver function, PA， Glu, RI and AKBR were measured preoperatively and on 1, 7,14th day after operation. Postoperative clinical course were also compared between the two groups. Results In the animal experiment group, as compared with the control group, AKBR was obviously higher (P＜0.01), seruim level of total protein and PA were increased faster (P＜0.05), and RL/W was higher. The mitotic index of liver cell was increased faster on 14th day, the numbers of regenerated liver cell with double nucleus and rough endoplasmic reticulum were higher in 14 and 28th day. In the clinical experiment group, as compared with the control group, serum total bilirubin, alanine aminotransferase and aspartate aminotransferase were lower on 7 and 14th postoperative day (P＜0.05). Serum albumin, PA, Glu, RI and AKBR were higher on 7, 14th postoperative day (P＜0.05). Conclusion Both experimental and clinical study show that the rhGH can promote liver regeneration and improve liver function after hepatectomy.
Objective To approach the prognosis after liver transplantation （LT） of liver function for Child grade A in patients with portal hypertension， and to compare with periesophagogastric devascularization with splenectomy （PDS）. Methods The data of 195 portal hypertension cases with Child A caused by hepatitis B cirrhosis who received surgical treatment of PDS （152 cases） or LT （43 cases） in division of liver transplantation center of West China Hospital of Sichuan University from 1999 to 2011 were retrospectively analyzed. The pre-， intra-， and postoperative variables in two groups that including patients’ age， score of Child， score of model for end-stage liver disease （MELD）， total bilirubin （TB），creatinine （Cr）， international normalized ratio （INR）， albumin （Alb）， complications of portal hypertension， amount of intraoperative bleeding and blood transfusion， operative time， and in the ICU and hospital stay time were compared. The postoperative outcomes were statistically analyzed including severe postoperative complications， short-term and long-term survival rates. Results Compared with PDS group， the amount of intraoperative bleeding and blood transfusion of LT group were morer （P＜0.05）， the operative time， in the ICU and hospital stay time of LT group were longer （P＜0.05）. The rate of severe postoperative complications in LT group was higher than that in PDS group 〔18.60% （8/43） vs. 1.97% （3/152），P＜0.05〕. The levels of TB and Cr during the postoperative period in LT group were higher than that in PDS group （P＜0.05）. Although the INR on day 1 after operation in LT group was higher than that in PDS group （P＜0.01）， but the difference disappeared soon on day 7 after operation in two groups （P＞0.05）.The 1-， 3-， and 5-year survival rates of the LT and PDS groups were 90.3%， 86.5%， 86.5%， and 100%， 100%， 100%， respectively， significant difference were observed in both short-term and long-term survival rates between the two groups （P＜0.05）. Conclusion LT offered no significant survival benefit to patients with portal hypertension and Child A due to hepatitis B cirrhosis， whereas PDS could be an effective treatment.
Objective To evaluate the changes of liver function after laparoscopic-assisted radical gastrectomy for gastric cancer and analyze related impact factors. Methods Patients with gastric cancer or colon cancer, who underwent radical gastrectomy or hemicolectomy between Jun 2008 and Jun 2010 in General Hospital of PLA, were included in this study. These patients were divided into open gastrectomy （OG group, n=43）, laparoscopic-assisted gastrectomy （LAG group, n=35）, and laparoscopic-assisted hemicolectomy （LAC group, n=23）. The serum AST, ALT, TB, and ALP levels of all patients enrolled on the preoperative day and post operative day （POD） 1, POD3, POD5, and POD7, and related impact factors were analyzed. Results Compared with the preoperative results, serum AST and ALT levels of patients increased until POD5 in both LAG and OG groups （P＜0.05）, and there was no changes in liver function after operation of patients in LAC group （P＞0.05）. In addition to that serum AST and ALT levels of patients in LAG group in POD1 were significantly higher than those in OG group （P=0.035 and P=0.041）， and that serum ALT level of patients in LAG group was significantly lower than that in OG group in POD3 （P=0.048）, serum AST and ALT levels of patients in two groups in the remaining time points were not statistically significant difference （P＞0.05）. The serum AST and ALT levels of patients in LAG group were significantly higher than those in LAC group during 5 d after operation （P＜0.05）.There was no significant changes of serum ALP and TB levels of patients in LAG and OG groups on the before and after operation （P＞0.05）. The increased serum ALT level of gastric cancer patients after operation related to body mass index （BMI, P=0.038）, operative time （P=0.011）, intraoperative hepatic injury （P=0.035）, and abnormal ligation of hepatic artery （P=0.048）, instead of the type of operation （OG vs.LAG, P＞0.05）. Conclusions Gastric cancer patients who underwent radical gastrectomy have transient liver dysfunction, which attributes mainly to direct liver manipulation or abnormal ligation of hepatic artery, but not CO2 pneumoperitoneum. Laparoscopic-assisted radical gastrectomy is feasible and safe to the patients without serious liver damage or other vital organs disorders.
We have measured the serum levels of total cholic acid (TCA) in 103 samples of obstructive jaundiced patients (OB group) and 83 samples of gallbladder stone patients without jaundice (control group) by enzymeconjugated colorimetric analysis method. The results revealed that TCA level was higher in OB group than in control group (Plt;0. 001) and had postive correlation with total bilirubin, direct bilirubin and alanine aminotransferase in OB group (Plt;0.01 in all). The clinical value of TCA in obstructive jaundice in comparison with alkaline phosphatase is discussed.
Abstract: Objective To evaluate the protective effects of Ulinastatin on the peri-operative liver and renal function in patients undergoing cardiac surgery for tetralogy of Fallot (TO F). Methods Thirty-eight patients with TOF were divided into Ulinastatin group and control group according to admission sequence, 19 cases in each group.For Ulinastatin group, intravenous Ulinastatin was given with a dosage of 10 000U /kg at 1h before operation, 1h and 24 h after operation. For control group, no Ulinastatin was given. 10 ml fresh urine and 2 ml blood samples were collected before operation, and postoperative 1h, 10h, 24h, 48h and 72h, respect ively. The liver and renal functions were measured. Fluid intake, urine output, chest drainage, dosage of furosemide, durations of mechanical ventilation and intensive care unit ( ICU ) stay were recorded. Results Neither arrhythmia nor low cardiac output syndrome occurred for both groups. No peri-operative death. Compared with control group, dose of furosemide, period of mechanical ventilation were lower, while urine output was higher in Ulinastat in group; the aberrant climax value of urine pro tein and N-acetylglucosam inidase (NAG) were lower in Ulinastatin group (10h post-operat ively, urinem icroalbum in: 65. 2 ± 58. 3mg/L vs. 71. 8 ±58. 9mg/L ; urine transferrin: 5. 8 ± 3. 6mg/L vs. 7. 4 ± 5. 4mg/L ; urine immunoglobulin G: 26. 9±20. 3mg/L vs. 31. 3±23. 3mg/L ; 1h post-operat ively; urine NAG: 61. 4±81. 6U /L vs. 76.1±48. 5 U /L ; P lt; 0. 05) and maintained in shorter period (P lt; 0. 05) , it returned to baseline value at 48h and 72 h post-operatively. The value of alanine aminotransferase (ALT) significantly increased post-operatively at every time points in control group (P lt; 0. 01) , w hile no obvious change in Ulinastat in group (P gt; 0. 05). The increased value of aspartate aminotransferase (AST ) in Ulinastatin group was significantly lower than that in control group (10h post-operat ively: 144. 4±20. 8U /L vs. 202. 7±74. 1U /L ; P lt; 0. 01). The value of AST returned to baseline value at 48h and 72h post-operat ively. Conclusion U linastatin is an effect ive strategy for protecting peri-operat ive liver and renal function of the patients with tetralogy of Fallot and the clinical application of Ulinastatin is safe and effective.
【Abstract】Objective To study the changes of insulin-like growth factor-1(IGF-1) in serum of patients with obstructive jaundice.Methods The clinical data of 20 patients with obstructive jaundice were collected and the measurement of serum TNFα,ALT, ALP, endotoxin and IGF-1 were performed. Results The serum IGF-1 in obstructive jaundice was significantly lower than that in gallbladder stone(P＜0.01), while endotoxin, TNF-α, ALT，ALP and TB were higher(P＜0.01). After the biliary duct obstruction was removed, the serum IGF1 in obstructive jaundice was significantly higher than that before operation and serum endotoxin， TNF-α, ALT， ALP and TB were significantly lower than that before operation(P＜0.01). A significant negative correlation was found between serum IGF-1 and serum endotoxin in benign obstructive jaundice(r=-0.761, P＜0.01). ConclusionIn obstructive jaundice, endotoxemia can affect the secretion of IGF-1 from liver. IGF-1 can be used as an index to judge the liver function in obstructive jaundice.
