RESUMO

Objective To analyze the clinical profile and short-term postoperative prognosis of mixed hepatocellular carcinoma and cholangiocarcinoma (mHCC-CC). Methods Clinical data of 17 mHCC-CC cases undergoing hepatectomy were retrospectively analyzed. Results Patients average age was 53 years (27~76 years).There were 11 males (64.7%) and 6 females.Ten patients (58.8%) were asymptomatic,twelve patients(70.6% ) had positive serology for hepatitis B infection,serum AFP levels >25 ng/ml in 12 cases. Serum CA199 levels ≥ 37 U/ml in 4 cases. All patients underwent radical hepatectomy,including > 1.5 cm safe margin and lymphadenectomy.The 6-,12-,and 18-months overall survival rate was 93.8%,86.5% and 57.7%,respectively.The 100- and 200-day disease-free survival was 65.3% and 43.5%.The median disease-free survival was 161 days. Conclusions mHCC-CC is difficult to diagnose preoperatively.The diagnosis depends on pathological examination.The main treatment was surgical resection.The prognosis of mixed primary liver cancer is poor and tends to recur early after hepatectomy.

RESUMO

AIM: To investigate the effects of alanyl - glutamine ( Ala -Gln) on expression of iNOS and TNF- α in injured intestinal mucosa induced by oral tacrolimus (FK506). METHODS: Twenty -four BALB/c mice were randomized to receive orally 0.2 mL of normal saline solution ( group Ⅰ ), 0.2 mL of FK506 in a dose of 0.1 mg/kg ( group Ⅱ ) or 1.0 mg/kg (group Ⅲ), and orally high -dose FK506 (0.2 mL, 1.0 mg/kg) plus intraperitoneal injection of Ala -Gln (0.5 g/kg )(group Ⅳ ),respectively. Damages of intestinal mucosa were determined by pathological examination.Intestinal mucosal permeability was analysed by FITC - dextran fluorescence assay. Expression of iNOS and TNF - α in intestine was detected by RT - PCR and Western blotting. RESULTS: Severe damage on the villi and increased intestinal permeability were observed in high - dose FK506 treated mice according to scanning electron microscopy and FITC - dextran flux respectively. The erosion and increased intestinal permeability were significantly alleviated by Ala - Gln treatment. Transcription of iNOS mRNA and TNF - α mRNA, which was up - regulated in high - dose FK506 treated group,was also markedly down- regulated in mice combined with Ala- Gln- treatment. A significantly increased expression of iNOS and TNF - α protein was found in the high - dose FK506 treated mice, while small amounts of these proteins were identified in the Ala - Gln - treated group. CONCLUSION: FK506 could induce a significant impairment of intestinal mucosa morphologically, which might be associated with up - regulated expression of iNOS and TNF - α in small intestinal mucosa. Subsequently, the intestinal permeability is increased. Ala - Gln has a strong protective effect on FK506 - induced intestinal barrier dysfunction, probably relates to the down - regulation of iNOS and TNF - α expression.

RESUMO

Objective To explore the cause of and treatment for psychiatric complications developed in the early stage after liver transplantation. Method The clinical data of 125 patients who underwent liver transplantation in our hospital were analyzed retrospectively. Results There was no significant difference in gender,age,liver function and the blood cyclosporine A level between psychiatric complication (PC) patients and those without PC. The anhepatic time and the total operation time of the PC group were longer than that of the non-PC group ( P

RESUMO

AIM:To explore the effect of the pretreatment of hypertonic saline(HTS) in hepatic ischemia reperfusion(I/R) injury.METHODS:The rats were divided into sham group(sham group),ischemia reperfusion group(IR group) and pretreatment of hypertonic saline group(HTS group).Partial hepatic ischemia reperfusion model was used.The rats were sacrificed at the time of 1 h,3 h,6 h,12 h and 24 h after reperfusion in each group,respectively.Blood samples were obtained to examine ALT.The expression of the CD11b/CD18(Mac-1) on the neutrophils was analyzed by flow cytometry.RT-PCR and Western blotting were used to examine the expression of intercellular adhesion molecule-1(ICAM-1) in livers and chromatometry was performed to detect the activity of myeloperoxidase(MPO) in livers.The morphology of hepatocytes and the structure of sinusoid were observed by histological examinations.RESULTS:① HTS pretreatment decreased the level of ALT at the time points of 3 h,6 h and 12 h after reperfusion(P

RESUMO

AIM: To investigate the effects of alanyl-glutamine (Ala-Gln) on expression of iNOS and TNF-? in injured intestinal mucosa induced by oral tacrolimus(FK506).
