RESUMO
OBJECTIVE: To investigate the serum levels of sCD44v6 and sE-cadherin (sE-cad) in patients with esophageal squamous cell carcinoma. METHODS: The serum samples were collected from 65 cases of esophageal squamous cell carcinoma, 32 cases of erosive esophagitis and 35 healthy subjects. Serum sCD44v6 and sE-cad levels were measured by enzyme linked immunosorbent assay (ELISA). RESULTS: The mean levels of serum sCD44v6 and sE-cad in esophageal squamous cell carcinoma patients were significantly higher than those of erosive esophagitis patients and normal controls (both P<0.05). There was no significant difference in serum sCD44v6 and sE-cad levels between erosive esophagitis patients normal controls (P=0.566 and P=0.708, respectively). Serum sCD44v6 and sE-cad levels of esophageal cancer patients were not correlated with their clinicopathological features. Serum sCD44v6 level is not correlated with sE-cad level in squamous cell carcinoma patients(P=0.651). CONCLUSION: Serum sCD44v6 and sE-cad might be a potential marker for screening of esophageal squamous cell carcinoma.

BACKGROUND: Mizoribine (MZR) was effective and safe for living Chinese donor kidney transplantation (LDKT) on tacrolimus-based treatment 1 year after transplantation. We investigated whether MZR was effective and safe for LDKT on tacrolimus-based treatment with long follow-up periods. METHODS: We compared 22 LDKT recipients who were administered MZR, tacrolimus, and corticosteroids with a control group (n = 20) treated with mycophenolate mofetil (MMF), tacrolimus, and corticosteroids. Primary efficacy endpoints were 3-year patient survival, 3-year graft survival, and acute rejection (AR) rate within 3 years after transplantation. RESULTS: The 3-year patient and graft survival rates for the MZR and MMF groups were 100%. The AR rate after transplantation was 18.2% for the MZR group and 10.0% for the MMF group; the difference was not significant (P = .665). There was no significant difference in serum creatinine levels, glomerular filtration rates (eGFR), serum urate levels, blood urea nitrogen, and cystatin C levels 12, 24, and 36 months after transplantation. No significant differences in the CD3, CD4, CD8, CD4/CD8, and CD45 were observed between the 2 groups 12, 24, and 36 months after transplantation. There were no significant differences in adverse events among the MZR or the MMF group, whereas the prevalence of gastrointestinal symptoms were significantly lower in the MZR treatment group (P = .003), especially acid reflux (P = .007). Compared with the MMF group, the MZR group should lighten the burden on patients. CONCLUSION: MZR with tacrolimus and corticosteroids provides satisfactory immunosuppression and higher safety for Chinese LDKT over a 3-year follow-up.

BACKGROUND: Although mizoribine (MZR) is used as an immunosuppressant after renal transplantation, the occurrence of hyperuricemia has been reported. The onset of hyperuricemia is often observed within the first several months after surgery. Since MZR is a renal excretion-type drug excreted as an unchanged drug from the kidneys, MZR blood concentrations may rise due to the influence of renal function. We investigated whether the onset of hyperuricemia after MZR administration was associated with the direct effect of a change in renal function. METHODS: Serum uric acid (serum UA), serum creatinine (sCr), serum ß2-microglobulin (serum ß2-MG), and serum cystatin C (serum Cys-C) were measured for about 3 months in 22 subjects. Correlation coefficients were calculated using the change rates of serum UA and sCr (Δ serum UA, Δ sCr), serum UA and serum ß2-MG (Δ serum UA, Δ serum ß2-MG), and serum UA and serum Cys-C (Δ serum UA, Δ serum Cys-C) at the onset of hyperuricemia. RESULTS: The correlation coefficients between Δ serum UA and Δ sCr, Δ serum UA and Δ serum ß2-MG, and Δ serum UA and Δ serum Cys-C were 0.723 (P < .001), 0.863 (P < .001) and 0.548 (P < .001), respectively. Further, serum UA and sCr level reached their highest peak on the same day after MZR administration, and the behavior was mostly consistent. CONCLUSION: It was suggested that hyperuricemia occurred about 3 months after MZR administration due mainly to temporary changes in kidney function.

BACKGROUND: Although liver transplantation has become a standard therapy for end-stage liver diseases, the experience of pediatric liver transplantation is limited in China. In this article we report our experience in pediatric liver transplantation, and summarize its characters in their indications, surgical techniques, and postoperative managements. METHODS: Thirty-one children (< or = 18 years old) underwent liver transplantation in our centers. The mean age at transplantation was 12.4 years old (ranged from 5 months to 18 years) with 7 children being less than 4 years of age at transplantation. The most common diagnosis of patients who underwent liver transplantation were biliary atresia, Wilson's disease, primary biliary cirrhosis, glycogen storage disease, hepatoblastoma, urea cycle defects, fulminant hepatic failure, etc. The surgical procedures included 12 standard (without venovenous bypass), 6 pigyback, 6 reduced-size, 3 split, 3 living donor liver transplantation, and 1 Domino liver transplantation. The triple-drug (FK506, steroid, and mycophenolate mofetil) immunosuppressive regimen was used in most of patients. Patients were followed up for a mean of 21.8 months. RESULTS: Five of the 31 patients died during perioperative time; mortality rate was 16.1%. The reasons of death were infections, primary non-function, heart failure, and hypovolemic shock. Postoperative complications in 10 patients included biliary leakage, acute rejection, abdominal infection, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, and pulmonary infection. Overall patient cumulative survival rate at 1-, 3-, and 5-year was 78.1%, 62.6%, 62.6%, respectively. CONCLUSIONS: The most common indications of pediatric liver transplantation were congenital end-stage liver diseases. According to patients' age and body weight, standard, piggyback, reduced-size, split, or living donor liver transplantation should be performed. Pediatric liver transplantation especially requires higher surgical skills. The early postoperative management is the key to success. Postoperative bile leak was common, but most patients underwent liver transplantation had a better prognosis.

BACKGROUND: With the maturation and popularization of skills in liver transplantation (LT), patients with hepatocellular carcinoma (HCC) have an alternative choice. LT as a curative treatment for HCC provides good liver function and systemic condition to recipients. Preoperative tumor characteristics are critical in selecting optimal candidates for LT to optimize the use of donor livers and to achieve a long-term survival. The present study aimed to elucidate the risk factors of HCC involved in fatal recurrence in the first year after LT and to investigate their utility in selecting suitable candidates for LT. METHODS: From April 2002 to October 2005, 303 patients who had received orthotopic LT for HCC were reviewed. Of these patients, those with diffuse intrahepatic or multiple systemic recurrent lesions who died within 1 year after surgery were investigated as fatal recurrence group (48 patients) and the remaining patients including those who were disease-free without recurrence, those who were alive with recurrence in the first year, or those who died in the first year of other causes, served as control group (255). The two groups were compared by demographics, tumor, and histopathological characteristics for their prognostic significance by logistic regression analysis. RESULTS: Multivariate analysis between the fatal recurrence group and the control group showed that the presence of vascular invasion, a tumor size greater than 6.5 cm, and a preoperative serum alpha-fetoprotein (AFP) level greater than 1000 mug/L were risk factors for fatal recurrence. Increased risk factors reduced the suitability of candidates for LT and diminished survival in the first year. 85.71% of the patients with all three risk factors, 37.84% of those with two factors, 13.64% of those with one factor, and 6.71% of those without risk factors died from tumor recurrence within 1 year after transplantation. CONCLUSIONS: Vascular invasion, tumor size > or =6.5 cm, and preoperative serum AFP level > or =1000 microg/L were significant predictors of fatal recurrence after LT for HCC. Patients with two or more risk factors should not be candidates for LT.

OBJECTIVE: To summarize the Patho-typing and the clinical manifestation of biliary cast syndrome (BCS) in patients after orthotopic liver transplantation. METHODS: The clinical manifestation, findings,therapeutic means and efficacy of 103 patients with biliary cast syndrome after orthotopic liver transplantation were retrospectively analyzed. According to the injury level of biliary duct epithelium, patients were divided into different groups. All cases were followed up for twelve months. The place, degree and time after operation would be recorded when non-anastomotic biliary stricture was found. RESULTS: There were 59 BCS cases in the general hospital of armed police force of China. The incidence rate of BCS was 9.1%. Many BCS patients showed symptoms such as jaundice, deep urine color, gray stools, itch of skin and fever. Some were asymptomatic. In laboratory test, the liver functional enzyme in serum were increased, the total white cell count in peripheral blood was increased either. Cholangiography via T tube of biliary tract might show filling defect. According to the change degree of the biliary tract tree, there were four types filling defect concluded from all the presentation in BCS patients. Solid obturation of biliary tract were found by the check with optical fiber choledochoscope in all BCS patients, necrosis of biliary tract epithelium were observed in partial BCS patients. According to the injury level of biliary duct epithelium (gradually aggravated), BCS patients were divided into six groups (type I, type II, type III, type IV, type V and type VI). Fourteen cases were found in type I and 18 in type II. No clinical symptom was found in these two groups, a few indicators in serum (alanine aminotransferase ALT, total bilirubin TBIL, direct bilirubin DBIL) were in normal range, and others (gamma-glutamyl transferase GGT, alkaline phosphatase ALP) were heightened in 5 patients. There was no biliary cast (BC) found anymore in the period of follow-up in two groups. No stricture was found in both group. Twenty-seven cases in type III and 23 cases in type IV, it was found there were about 33.4% patients accompanied with fever and 25.9% accompanied with jaundice in type III. Paralleled,there were about 30.4% and 34.8% patients in type IV. The liver functional enzyme in serum were found increased in both type. After supporting treatment for 3-6 months,there were 5 and 3 patients present as mild non-anastomotic biliary stricture in type III and type IV group. In the group type V, there were 13 patients. The detected liver functional indicators in serum were increased. After supporting treatment for 6-12 months,there were 4 patients present as moderate non-anastomotic biliary stricture in this group. There were 18 patients in type VI group, all indicators of the liver functional enzyme in serum before the treatment were elevated conspicuously. All patients in this group were found serious stricture up to three places that have not been sustained in the period of follow-up. Nine died of MOSF, 1 died of AOSC, 8 had undergone retransplantation. In the retransplantation patients, 4 died of post operation MOSF, 3 recovered to normal, 1 patient was found BCS once more 15 d after the retransplantation and the third-transplantation was performed 7 months after the second transplantation, no BCS was found again. The deaths total rate was 13.6%, death rate of retransplantation was 44.0%, total cure rate was 54.0%, total improvement rate was 71.0% and total stenosis rate was 29.0%. CONCLUSIONS: (1) According to the check with optical fiber choledochoscope, there are 6 types of patho-typing in BCS patients. The clinical manifestation includes jaundice and fever. The filling defect of the biliary tract tree might showed 4 appearances. (2)The patho-typing contributes to the clinical manifestation and the filling defect of the biliary tract tree.

OBJECTIVE: To summarize the clinical efficacy of pediatric liver transplantation, and investigate the characters of pediatric liver transplantation in their indications, surgical procedures and postoperative management. METHODS: From August 2000 to March 2007, 23 liver transplantations were performed on 20 children, aging from 6 months to 13 years old. The most common indications were biliary atresia, Wilson's disease, glycogen storage disease and urea cycle defects. Surgical procedures included 4 living donor liver transplantations, 1 Domino liver transplantation, 5 split grafts, 10 reduced liver grafts and 3 whole cadaveric grafts. The triple-drug (FK506, steroid and MMF) immunosuppressive regimen was used in 19 children, except one children using cyclosporine. RESULTS: Three children died of primary non-function, heart failure and abdominal infections respectively during peri-operative period, and the mortality was 15.0%. Nine children showed different post-operative complications including 2 hepatic artery thrombosis, 1 portal vein thrombosis, 1 acute rejection, 3 biliary leakage, 2 biliary stricture, 2 intestinal fistula, 3 abdominal infection, 1 pulmonary infection and 1 heart failure. Cumulative patient survival rates at 6-month, 1-and 2-year were 80.0%, 73.9% and 73.9%, respectively. CONCLUSIONS: Liver transplantation is an effective option to cure the liver disease of children with end-stage. Different surgical procedure could be chosen according to the children's age and body weight.

The aim of this study is to investigate whether the expression of CD147 could be a prognostic factor for hepatocellular carcinoma. Tissue samples from 111 hepatocellular carcinoma patients were immunohistochemically stained with anti-CD147, anti-matrix metalloproteinases-2 and anti-vascular endothelial growth factor antibodies. Tumor microvessel density was evaluated using CD34. The survival curves were estimated by Kaplan-Meier analysis and the prognostic significance of the marker was analyzed using the log-rank test. In addition, the identification of relevant prognostic factors was performed by multivariate Cox regression analysis. CD147 was mainly expressed in cancerous lesions and its expression was positively correlated with metalloproteinases-2 (P<0.0001), vascular endothelial growth factor (P<0.0001) and microvessel density CD34 (P<0.0001). Furthermore, CD147 was significantly associated with the presence of venous invasion (P=0.0013), tumor size (P<0.0001) and pTNM tumor stages (P=0.0001), as well as serum alpha-fetoprotein level (P<0.0001). Patients with positive expression of CD147 had poorer tumor recurrence-free survival than those with negative expression of CD147 (P<0.0001). Analyzed by a proportional hazard model, strong expression of CD147 had the highest risk ratio of recurrence among these markers (P<0.0001). The findings suggest that CD147 may be a significant independent predictor of poor survival in patients with hepatocellular carcinoma, and may be involved in tumor growth, invasion and angiogenesis in hepatocellular carcinoma.

OBJECTIVE: To retrospectively evaluate the clinical outcomes of liver transplantation for patients with hepatocellular carcinoma (HCC). METHODS: The clinical data of 88 consecutive HCC patients who underwent orthotopic liver transplantation between 2002. 4 and 2004. 7 were retrospectively reviewed. HCC stage of those patients were defined according to the pTNM classification system of UICC. All patients were followed up for more than 12 months after liver transplantation. The recurrence and overall survival rate were evaluated by univariate and multivariate analysis with SAS software. RESULTS: The cumulative 1-year recurrence rate of stage I, II, III and IV after liver transplantation was 0%, 4.8%, 40.0% and 71.3%, respectively (P < 0.01). The cumulative 1-year overall survival rate of stage I, II, III and IV was 100%, 95.2%, 71.5% and 41.7%, respectively (P < 0.01). CONCLUSION: Liver transplantation may be suitable for stage I or II hepatocellular cancer patients and improve their prognosis, while it is not suitable for stage IV HCC patients.

OBJECTIVES: To explore the diagnostic value of color Doppler flow imaging (CDFI) in monitoring portal vein complications (PVC) following orthotopic liver transplantation (OLT). METHODS: Five hundred and four patients received OLT and had CDFI examinations before and after their transplantations. CDFI monitoring parameters before the operation included portal vein diameter, blood flow velocity and the presence of thrombi within the portal vein. Monitoring parameters after the operation included portal vein diameters of donor and receiver sides, and the diameter of the mouth of anastomosis, inner side of blood vessel echo, the direction of blood flow and its speed. RESULTS: Of the 504 patients examined, the median velocity of the portal blood flow was 46.27 cm/s (range: 15.8 to 110.8) on the day of the operation. The blood flow speed of 358 cases (71.03%) was higher than 40 cm/s. Of the 358 patients, 347 (68.85%) had a blood flow speed lower than 40 cm/s one month after the operation. Sixty-four patients (12.70%) showed hepatofugal blood flow once, and only one case had a total hepatofugal blood flow. Thirteen patients (2.58%) had portal vein complications, including 4 cases with portal vein thrombosis and 9 with portal vein stenosis. CONCLUSION: Not all abnormal portal vein blood flow signals will lead to complications. It is worthwhile to monitor the portal blood flows. CDFI plays an important role in the diagnosis of portal vein complications after orthotopic liver transplantation.

OBJECTIVE: To evaluate the efficacy and safety of hepatitis B immunoglobulin (HBIG) by different medicating ways in patients with liver transplantation and to explore the methods for calculating the intravenous loading dosage of HBIG. METHODS: The patients enrolled were randomized into three groups (i.v group, i.m group and domino group). Under the combined utilization with Lamivudine, HBIG was given in different ways during anhepatic phase and the postoperative six days. The physical examination was done, the serum conversion rate of HBsAg was studied, the serum level of HBsAb titer, WBC, PLT, AST, GGT, TBIL, DBIL, CR, PT and PTA were tested daily within the postoperative seven days. The preoperative body weight, serum HBsAg and HBeAg titer were analyzed with the intravenous loading dosage of HBIG by multiple-factor linear regression (Stepwise). RESULTS: Both the average negative-conversion rate of serum HBsAg and the average increasing rate of serum HBsAb titer are significantly faster in i.v group and domino group than that in i.m group within the postoperative four days (P < 0.05). The regression equation to calculate the i.v loading dosage of HBIG (IU) by preoperative criteria was drawn as 1123 + 3.4 x serum HBsAg titer (IU/L) +73 x body weight (kg). There was no linear correlation found between the level of HBeAg and the loading dosage of HBIG. There were no significant difference in body temperature, pulse rate, respiratory rate, blood pressure, WBC, PLT, AST, GGT, TBIL, DBIL, CR, PT and PTA among the three groups within the postoperative seven days (P < 0.05). The rate of the second elevation of serum ALT was 10.3% (3/29), 3.4% (1/29) and 6.7% (2/30) in i.v group, i.m group and domino group, respectively (P < 0.05), and the rate of the local complications (sclerosis, edema, pain) at the injection site was 0, 89.6% (26/29) and 0, respectively (P < 0.05). CONCLUSIONS: Based on the combined utilization of lamivudine and HBIG, the qualified intervention efficacy, less complications could be obtained by medicating HBIG in a domino way (i.v first, followed by i.m), which is worthy to be promoted.

Canopy temperature is one of promising signals for evaluating crop water status. The infrared thermal imager can provide real-time temperature distributions over larger areas with high spatial resolution. The main factors (the observation orientation, angle and distance) controlling the accuracy of measuring canopy temperature with the infrared thermal imaging were investigated in a cotton field. Moreover, the correlation relationships between the crop water stress index (CWSI), which was observed using different methods, and soil water content (SWC), leaf water potential (LWP), and stomatal conductance (g(s)) of cotton in different water treatments were analyzed. Results indicated that the CWSI, which was measured in the opposite direction of the sun with the observation angle of 45°, was in good correlation with LWP, g(s) and SWC, indicating it was a suitable observing method of canopy temperature. The canopy temperature gradually decreased with the increasing observation distance, so the calibration was necessary for long-distance measurement. By analyzing the relationship between the temperature at the dry/wet reference surface and the canopy temperature, we developed a suitable and simplified model of CWSI for cotton in the North China Plain.

AIM: To determine whether diabetes mellitus (DM) affects prognosis/recurrence after liver transplantation (LT) for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). METHODS: A retrospective study was conducted between January 2000 and August 2013 on 1631 patients with HBV-related HCC who underwent LT with antiviral prophylaxis. Patient data were obtained from the China Liver Transplant Registry (https://www.cltr.org/). To compare the outcomes and tumor recurrence in the HBV-related HCC patients with or without DM, statistical analyses were conducted using χ2 tests, Mann-Whitney tests, the Kaplan-Meier method, log-rank tests and multivariate step-wise Cox regression analysis. RESULTS: Univariate analysis of 1631 patients who underwent LT found overall 1-, 3- and 5-year survival rates of 79%, 73% and 71% respectively in the DM patients, and 84%, 78% and 76% in the non-DM patients respectively. Overall survival rate differences after LT between the two groups were significant (P = 0.041), but recurrence-free survival rates were not (P = 0.096). By stratified analysis, the overall survival rates in DM patients for age > 50 years (P = 0.002), the presence of vascular invasion (P = 0.096), tumors ≤ 3 cm (P = 0.047), two to three tumor nodules (P = 0.007), Child-Pugh grade B (P = 0.018), and pre-LT alanine aminotransferase levels between 40 and 80 IU/L (P = 0.017) were significantly lower than in non-DM patients. Additionally, serum α-fetoprotein level > 2000 ng/mL (P = 0.052) was associated with a significant survival difference trend between DM and non-DM patients. Multivariate analysis showed that the presence of DM (P < 0.001, HR = 1.591; 95%CI: 1.239-2.041) was an independent predictor associated with poor survival after LT. CONCLUSION: HBV-related HCC patients with DM have decreased long-term overall survival and poor LT outcomes. Prevention strategies for HCC patients with DM are recommended.

Parents of liver transplant recipient children have to face complicated health issues of their children. Coping strategies of parents as major care providers not only impacts on their handling of stresses on themselves but also on the recipients' quality of life. In this study, we sought to investigate the coping strategies of parents of Chinese pediatric liver transplant recipients at a single tertiary care institution in China. Twenty-five parents of liver transplant recipients were selected by the purposive sampling method and data was collected using qualitative semi-structured interview. Interviews were conducted until thematic saturation was achieved. We extracted 5 major themes: 1) guilt and self-blame for not giving a happy life to the sick child; 2) seeking social support for helping to treat the sick child; 3) standing firm by not giving up on treating the sick child; 4) cautious caretaking; 5) compromise: a helpless acceptance of truth. In summary, parents of transplant recipients present 5 major coping strategies. Proper assessment of stresses on parents of liver transplant recipient children and their coping strategies may help the medical staff and social services to provide more targeted support, and help and promote the balance of the family function.
RESUMO
OBJECTIVES: To summarize the pathotyping and clinical manifestations of biliary cast syndrome in patients after an orthotopic liver transplant. MATERIALS AND METHODS: The clinical manifestations, auxiliary examination, therapeutic regimen, and clinical efficacy of 103 biliary cast syndrome patients who underwent an orthotopic liver transplant were retrospectively analyzed. Patients were divided into 6 groups from type 1 to type 6, according to the injury level of the biliary duct epithelium. RESULTS: Many biliary cast syndrome patients showed symptoms including jaundice, dark urine, argillaceous stool, itchy skin, and fever. Serum levels of alanine aminotransferase, γ-glutamyl transpeptidase, alkaline phosphatase, and total bilirubin were increased. In addition, total white cell counts in peripheral blood also were increased. T-tube cholangiography showed filling defects of various amounts. Optical fiber choledochoscope examination revealed that the biliary tract was filled with solid substances, and necrosis of the biliary tract epithelium was observed in some biliary cast syndrome patients. From type 1 to type 6 biliary cast syndrome patients, the probability of clinical symptoms and biliary tract stricture gradually increased, the time needed for supporting gradually prolonged after removal of the biliary cast, and T-tube cholangiography showed that the filling defects gradually expanded. CONCLUSIONS: Clinical manifestations and cholangiography presentations mainly depend on pathotyping.

Cardiac arrest during upper abdominal surgery such as liver transplantation is a rare but very severe complication. Traditional external cardiac compression has been the mainstay of basic life support in general circumstances. Subdiaphragmatic cardiac compression (SDCC), with no incision in the diaphragm, may be a more effective measure. This maneuver can provide more effective and timely cardiac compression via the already open abdomen in surgery and not add extra trauma. This method can provide a quicker and more effective means of circulation support for intraoperative cardiac arrest patients without adding new injuries. Five cases are reported and all the patients had return of spontaneous circulation (ROSC). This is the first report of the SDCC method.

UNLABELLED: Orthotopic liver transplantation (OLT) is the only curative therapy of HCC with underlying cirrhosis, but due to HCC metastasis and recurrence, its benefit is limited to a small population who meet the strict selection criteria. We previously reported that Licartin ([131I] mAb HAb18G/CD147) was safe and effective in treating HCC patients, and its antigen, HAb18G/CD147, was closely related to HCC invasion and metastasis. Here, we reported a randomized controlled trial to assess the post-OLT antirecurrence efficacy of Licartin in advanced HCC patients. We randomized 60 post-OLT patients with HCC, who were at tumor stage 3/4 and outside the Milan criteria before OLT, into 2 groups. Three weeks after OLT, the treatment group received 15.4 MBq/kg of Licartin, while the control group received placebo intravenously for 3 times with an interval of 28 days. At 1-year follow-up, the recurrence rate significantly decreased by 30.4% (P = 0.0174) and the survival rate increased by 20.6% (P = 0.0289) in the treatment group, compared with those in the control group. For the control group versus the treatment group, the hazard ratio for recurrence was 3.60 (95% confidence interval [CI], 1.50-8.60) and that for death was 3.87 (95% CI, 1.23-12.21). Licartin treatment also resulted in an earlier decreased AFP level and a longer time of normal AFP level than placebo (P = 0.0016). No Licartin-related toxic effects were observed. CONCLUSION: Licartin is a promising drug for preventing post-OLT tumor recurrence in advanced HCC patients excluded by the currently strict criteria for OLT. HAb18G/CD147 can be a good drug target.
