Objective To investigate the changes of fractalkine (FKN) in rat model of acute liver failure (ALF) and the role of FKN in liver inflammatory injury.Methods SD rats were divided into tWO groups:6 in normal group and 36 in model group.D-galactosamine(D-Gal) was used to induce ALF in model group.The sera and hepatic tissue samples were collected at 12,24,48,72,120 andl68 h.After D-Gal injection.FKN mRNA and nuclear factor(NF)-kB mRNA in hepatic tissue samples were detected by reverse transcription-polymerase chain reaction (RT-PCR).Results The levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) at 12 h were(208.3±43.5)U/L and (375.2±117.3)lJ/L,respectively,which were both significantly higher than those in normal group[(31.8±2.9)U/L and (90.8±3.1)U/L](t=-9.912 and-5.935,respectively,both P<0.01);the levels of ALT and AST peaked at 72 h after D-Gal injection.The levels of FKN mRNA(O.086±0.009)in model group at 12 h were significantly higher than those (O.044±0.009) in normal group(t=-7.999.P<0.01),and peaked at 72 h (O.333±0.033),then decreased obviously at 120 h. The levels of NF-KB mRNA in the liver of normal rats were very little;and the levels in model group were increased gradually over time,then peaked at 72 h (O.583±0.i01,t=-12.607,P<0.01).FKN mRNA and NF0kB mRNA were positively correlated (r=0.760,P<0.01).Conclusion The FKN expression may play all important role in liver inflammatory injury in rat model of acute liver failure, which could provide a new approach for ALF therapy.

Objective To evaluate the therapeutic effects of recombinant expression plasmid containing hepatocyte growth factor (HGF) and augmenter of liver regeneration (ALR) on rats with hepatic fibrosis. Methods Ninety Sprague-Dawley rats, which had been established into hepatic fibrosis models, were equally divided into 6 groups: blank group, pcDNA3.1 therapy group,pcDNA3.1-HGF therapy group, pcDNA3. 1-ALR therapy group, pcDNA3.1-HGF and pcDNA3. 1-ALR combined therapy group, and pcDNA3. 1-HGF-ALR therapy group. Zero point one μmol of blank or plasmid was injected into model rats in each group by tail vein once a day for 3 days. Model rats in blank group didn't receive any treatment. Additional 10 rats were chosen as control group, which were not given any interference during the experiment. All rats were sacrificed 4 days after end of treatment. Liver tissues were reserved for observing pathologic changes after HE staining and detecting proliferating cell nuclear antigen (PCNA) and c-jun by immunohistochemistry. Measurement data were compared by single-factor analysis of variance. Comparison between groups was done by SNK test. Enumeration data were analyzed by Fisher's exact test. Results In blank group and pcDNA3.1 therapy group, hyperplasia of fibrous connective tissue was very obvious, false lobules were formed. There was no significant difference between these two groups (x2 =0. 317,P= 1. 000).In the 4 remaining groups, hepatic fibrosis all achieved different degree of amelioration, and the therapeutic effect of pcDNA3.1-HGF-ALR was optimal. In control group, the expressions of PCNA and c-jun in liver tissues were low, with absorbance value of 8.6±1.9 and 3.2 ± 1.2, respectively. In blank group and pcDNA3. 1 therapy group, the expressions of PCNA and c-jun were obviously increased, with absorbance value of 24. 1±3.0, 24.5±4.3 and 23.8±3.1, 24.9±4.2, respectively,which were significant different from control group (all P＜0.01). In the 4 remaining groups, the expressions of PCNA were all obviously increased, and expressions of c-jun were all obviously decreased. The maximum change scope was observed in pcDNA3. 1-HGF-ALR therapy group.Conclusions The recombinant expression plasmid pcDNA3. 1-HGF-ALR can effectively ameliorate experimental hepatic fibrosis of rats. The anti-fibrosis effects are achieved probably by up-regulating PCNA expression and down-regulating c-jun expression.

Objective To evaluate the treatment effect of acute liver failure(ALF) by xeno-transplantation of co-microencapsulated Sertoli cells and hepatocytes and the intraperitoneal immune privilege effects of Sertoli cells on hepatocytes. Methods ALF rats were induced by intraperitoneal injection of D-galactosamine and, thereafter, were treated with physical saline, free hepatocytes, microencapsulated hepatocytes, or co-microencapsulated Sertoli cells and hepatocytes (CMSH), respectively. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and total bilirubin (TBil) were detected in rats' blood samples from various groups. Expression of Smac/Diablo and caspase-3 were determined by reverse transcription-polymerase chain reaction (RT-PCR). Fifteen rats in each group were used for survival rate analysis. The intraperitoneal microencapsules were observed and lymphocytes in ascites were counted. The data were analyzed by multi-factor or single factor analysis of variance and the comparison between groups was done by t test. Results In CMSH treatment group, ALT level decreased to (533.7 ± 76.5) U/L, AST level decreased to (381.2 5± 46.7) U/L after 48 h. TBil level reduced to (7.36 ± 2.18) μmol/L after 72 h. Albumin level increased to (28.4±2.5) g/L after 48 h. All these values were significantly different from those in other groups (F=10.7,6.5,12.2,8.4;P＜0.05). The expression levels of Smae/Diablo and caspase-3 mRNA at 48 h and 72 h were lower in CMSH group than in other groups (F=3.7,4.8,3.6,4.2; P＜0.05). Survival rates in microencapsulated hepatocytes group and CMSH group were similar while both of them were higher than other groups. Microencapsules neither in microencapsulated hepatocytes group nor in CMSH group were adhered to intraperitoneal mucosa. Lymphocyte counts in ascites of CMSH group were lower than those in microencapsulated hepatocytes group (t= 4.21, P＜0. 05). Conclusions Intraperitoneal transplantation with CMSH is a promising approach for ALF treatment. Furthermore, Sertoli cells can help reduce lymphocytes' aggregation caused by encapsulated hepatocytes in ascites.

Background and purpose: 18F-FDG has been considered to be of limited value for the detection of bladder lesions because of interference by the 18F-FDG excreted in urine. Delayed pelvic images with“diluted and iflled bladder”use a method of 18F-FDG PET/CT with delayed images after oral hydration so as to increase the detection rate of 18F-lfuorodeoxyglucose(FDG) PET/CT imaging for the lesions of bladder. Methods:48 patients with bladder lesions(35 patients with bladder primary tumor and 13 patients with metastatic tumor) underwent 18F-FDG PET/CT detection and were required oral hydration of 1200-1800 mL water, urination frequently, holding urine when the more scan began. Lesions conifrmed by histopathology, MRI, CT or clinical follow-up at least 1 year. Results:89%(43/48) of patients were obtained good clearance and the urine SUVmax declined from 33.14(9-66.80)to 3.23(1.35-5.65) signiifcantly and the statistical difference was signiifcant (t=8.703, P<0.01). The interval time between two scan was 2 h approximately. At the same time, the SUVmax of bladder lesion was 2.8-25.0. Detection sensitivity, speciifcity and accuracy were 90.47%(19/21), 81.48%(22/27)and 85.41%(41/48), respectively. Conclusion: 18F-FDG activity in the bladder signiifcantly decreased in most patients with“diluted and iflled bladder”. The PET/CT scan can highly detect lesions of bladder tissues. Our method with high accuracy and better endurance could be applied to detect the lesions in bladder.
