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 explore the changes in the serum Cu2+and the indexes for the liver pathology and biochemistry before and after the copper needle retained in the central veins of the rabbit ears. Methods Fortynine New Zealandrabbits were randomly divided into 5 groups: Group A (copper needles retained for 1 d), Group B (3 d), Group C (5 d), Group D (7 d), and Group E (the control group, without any copper needles retained). In each experimental group, there were 10 rabbits, and in the control group there were 9 rabbits. The rabbits in each group were arranged to have their venous blood drawn for determination of theCu2+concentration, and for observation on the changes in the liver biochemicalindexes for 5 times before and after the copper needles were retained in the central veins of the rabbit ears. At the same time, a piece of the liver tissue ineach rabbit was taken for examination of the pathological changes. All the liver samples were given the basic pathological examination; if the liver sample hadsome extraordinary pathological features, the specific pathological examinationwould be given, even using the transmission electron microscope. Results After the copper needles were retained in the central veins of the rabbit ears, the Cu2+concentration increased with the passing time. The concentrations in the groups were 1.40±0.49 μg/ml in Group A, 1.45±0.53 μg/ml in Group B, 2.01±0.40 μg/ml in Group C, 2.38±0.83 μg/ml in Group D, and 1.34±0.45 μg/mlin Group E, respectively. There was a statistically significant difference between Group D and Group E(P＜0.05). There were no significant changes in the ALT and AST levels when compared with those before the copper needles were retained(P＞0.05); however, there was a considerably positive correlation on 1st day (r=0.686, P＜0.05), 5th day (r=0.712, P＜0.05), and 7th day (r=0.768, P＜0.01) when compared with those after the copper needles were retained. The histological examination showed that aseptic inflammation subsided with the time in part of the liver. The Masson staining and the Ag staining showed that there were no obvious changes in the hepatic lobules, with no fibrosis of the liver tissues found under light microscope. Conclusion There are no obvious toxic and side effects on the rabbit liver after the copper needles are retained in its central veins.
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.
【 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.
Objective To estimate the relationship between arterial blood ketone body ratio (AKBR) and liver function and to appraise the feasibility of adding AKBR into liver function estimate. MethodsFrom 1994 to 1998, 44 patients with unresectable liver cancer recieved the combined radiochemoembolization with mixed emulsion of phosphorus32 glass microspheres (32PGMS), chemoagent and glycerine or lipiodol, via intraoperative hepatic artery instillation, hepatic artery ligation and operational arterial embolization (HAL+OAE) or transcatheter hepatic artery embolization (TAE). Preoperative and postoperative function and energy change level of the liver were tested by liver function test and AKBR. CT, SPECT, AFP were used to judge the therapy effect; multivariate statistical analysis methods were used to evaluate the correlation between AKBR and liver function. Spearmen rank correlation analysis was used to evaluate whether there was any relationship between AKBR and liver function test, and to evaluate that there was any relationship between AKBR and survival time. ResultsA negative correlation showed between the level of AKBR and liver function. The correlation coefficient of the three level of AKBR before operation and survival time was 0.4409. Conclusion AKBR can well reflect the degree of liver function.
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.
ObjectiveTo explore influence of different nutritional approaches on liver function in patients after esophagectomy. MethodsA total of 160 patients with esophageal cancer who underwent surgical treatment were divided into a enteral nutrition (EN) group and a total parenteral nutrition (TPN) group according to different medical staff. There were 80 patients in each group. Two and 7 days postoperatively, albumin (ALB), prealbumin (PA), alanine aminotransferase (ALT) and total bilirubin (TB) of the 2 groups were examined to evaluate liver function. ResultsAbnormities in liver function (ALB, PA, ALT, TB) was common phenomenon in esophageal cancer patients, but there was no statistical difference in ALB, PA, ALT, TB on the 2nd postoperative day between the EN group and the TPN group (P > 0.05). On the 7th postoperative day, liver functions were improved than those on the 2nd postoperative day in the two groups. And frequencies of liver function abnormity in the EN group were significantly lower than those in the TNP group (P < 0.05). ConclusionCompared with TPN, EN has advantages in facilitating hepatic protein synthesis and recovery of liver function after esophagectomy.
ObjectiveTo investigate the influence of enteral nutrition (EN) and total parenteral nutrition (TPN) on liver, kidney and gastrointestinal function in patients after esophagectomy. MethodsA total of 124 patients with esophageal cancer who underwent esophagectomy in the Affiliated Hospital of Guangdong Medical College from January 2012 to August 2013 were enrolled in this study. There were 71 male and 53 female patients with their average age of 59.7 years (range 31 to 85 years). All the patients were randomly divided into an experimental group and a control group. Postoperatively, patients in the experimental group received EN via nasogastric/nasointestinal tube, and patients in the control group received TPN. Preoperatively, 1, 3 and 7 days postoperatively, plasma alanine transaminase (ALT), aspartate transaminase (AST), indirect bilirubin (I_BIL), direct bilirubin (DB), total bilirubin (TB), total protein (TP) and albumin (ALB) were examined to evaluate liver function, blood urea nitrogen (BUN) and serum creatinine (Scr) were examined to evaluate renal function. Postoperative time to first audible bowel sounds, time to first flatus, and time to first stool were examined to evaluate gastrointestinal function. ResultsThere was no statistical difference in ALT, AST, I_BIL, DB or TB preoperatively and on the 1st postoperative day between the 2 groups (P > 0.05), but these parameters of the experimental group were significantly lower than those of the control group on the 3rd and 7th postoperative day (P < 0.05). There was no statistical difference in TP or ALB between the 2 groups (P > 0.05). There was no statistical difference in BUN or Scr preoperatively, on the 1st or 3rd postoperative day between the 2 groups (P > 0.05). BUN (4.94±1.07 mmol/L vs. 6.67± 2.88 mmol/L, P < 0.05) and Scr (52.50±12.46 μmol/L vs. 68.23±7.61 μmol/L, P < 0.05) of the experimental group were significantly lower than those of the control group on the 7th postoperative day. Postoperative time to first audible bowel sounds (42.00±1.68 hours vs. 50.00±1.54 hours), time to first flatus (64.15±10.35 hours vs. 70.64±14.73 hours) and time to first stool (4.20±1.50 days vs. 5.20 ±1.40 days) of the experimental group were significantly shorter than those of the control group (P < 0.05). ConclusionPostoperative EN can promote the recovery of gastrointestinal function, and has less influence on liver and kidney function, which is beneficial to postoperative recovery and morbidity reduction after esophagectomy.
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.
