Children with biliary atresia generally present nutritional deficiency, and often have growth failure and neurodevelopmental impairments.Increasing evidence shows that malnutrition is not only a risk factor for growth failure and neurodevelopmental impairments in children with biliary atresia, but also a risk factor for morbidity and mortality.Nutritional support is extremely important to improve the prognosis.This article reviews the relationship between malnutrition, growth failure and neurodevelopmental impairments in children with BA, and discusses the timing and methods of nutritional support.

Objective To investigate the effect of a dual regulation of replicating adenovirus vector carrying human endostatin gene (AdTPHre-hEndo) on pancreatic cancer. Methods Human endostatin (hEndo) gene was cloned into the genome of replicating adenovirus specific for the tumor cells by virus recombination technology. The virus titer was 3.25 × 1010pfu/ml. A Balb/c nude mouse model carring sw1990 cells pancreatic cancer was established, the expression of human endostain and inhibition of tumor cells in vivo were detected. Results We successfully constructed AdTPHre-hEndo. The inhibition on pancreatic cancer cell line SW-1990 of AdTPHre-hEndo is better than Ad-hEndo (P ＜0. 01 ), and ONYX-015 ( P ＜ 0. 05 ). The endostatin expression of AdTPHre-hEndo group was significantly higher than Ad-hEndo group and the control group (P ＜ 0. 01 ). The intratumoral MVD also decreased significantly in the treated tumors(6. 8 ±2. 5 vs. 16. 0 ±4. 6、47. 2 ± 10. 0, P ＜0. 01 ). Conclusions The recombination adenovirus can express biologically active hEndo effectively, which results in inhibiting the growth of micro-blood vessels and proliferation slowly.

Objective To analyze the short-term and long-term effectiveness of radiofrequency ablation combined with transcatheter arterial chemoembolization (TACE) for the treatment of hepatocellular carcinoma (HCC).Methods The clinical data of 70 HCC patients who had received thermal ablation (group A) done or in combination with TACE (group B) were retrospectively analyzed.Results The rate of intrahepatic distant recurrence in group B (25 cases) was lower than that in group A (45 cases) (X2 =3.845,P =0.046) and the tumor-free survival rate was higher than group A (X2 =5.020,P =O.030).There were no differences in the local tumor progression rate (X2 =0.853,P =0.374) and overall survival (x2 =2.316,P =0.154) between two groups.Incidence of bone marrow suppression in group B was higher than that of group A (X2 =5.642,P =0.042).Major complications didn't occur in any group(X2 =2.016,P =0.183).The costs was higher(t =7.738,P ＜0.001) and the hospital stay was longer (t =5.921,P =0.003) in group B than group A.Conclusions Compared with ablation alone,combined therapy is able to reduce short-term recurrence,and improve tumor-free survival.Combine therapy is safe and effective method for small liver carcinoma.

Objective To evaluate a thrombolytic system of portal vein port-catheter kit (PC) in the treatment of portal vein thrombosis (PVT). Methods In this study, 42 PVT patients with liver cirrhosis and portal hypertension after splenectomy from 2005 to 2007 were divided into two groups. In group A (20 eases) thrombolysis was administered through the PC device. Urokinase at the dosage of 1000 U?kg-1?h-1 was given for a consecutive 3 -6 days through the PC, and then the therapy was converted to 100 AxaIU/kg of low molecular heparin twice a day for 7 days subcutaneously. In group B, the thrombolysis was performed on 22 patients through peripheral veins. The therapy was same as in group A except for that the urokinase dosage was doubled. The complete thrombolysis rate, the effective thrombolysis rate, the time of thrombolysis, the long-term recurrence rate and the incidence of complication were compared between the two groups. Results The complete thrombolysis rate and the effective thrombolysis rate in group A were 75%, 90% respectively, compared with that of 41%, 59% respectively in group B. The significant differences in the complete thrombolysis rate, the effective thrombolysis rate, the time of thrombolysis and the incidence of complication were found between the two groups, while the thrombolysis recurrence rate had no significant difference between the two groups. Conclusion PC regime is an effective and safe method for the treatment of portal vein thrombosis.

Objective To construct the bioartificial liver by bone mesenchymal stem cell (BMSC) and alginate scaffold. Method Alginate scaffold was used as the cell carrier for the cultivation of BMSC and the differentiation from BMSC into hepatic like cells was induced by the cell factors of HGF, EGF and FGF-4 in the scaffold in vitro. The compatibility of the cells and the scaffold was observed by microscopy and the function of the differentiatd cells was tested. The gene of AFP and ALB was detected by RT-PCR. The secretion of ALB and the urea synthesis of the cells were tested by ALB kit and urea kit respectively. The glycogen synthesis and the CK-18 was tested by the glycogen stanning method and the immunofluorescence test. Results BMSC was able to attach, grow and proliferate well in the alginate scaffold, the well compatibility was observed by microscopy. ALB and urea were detected in the cultivating medium, the gene of ALB and AFP was identified by RT-PCR. The glycogen synthesis ability and the expression of CK-18 were induced during the differentiation. Conclusion The three dimensional atginate scaffold exhibited well compatibility with BMSC, BMSC could be differentiated into the hepatic like cell in the scaffold. BMSC and the alginate scaffold could be used to construct the bioartificial liver for the hepatic tissue engineering.

Objective To assess the value of thickness and arterial resistive index (RI) of wrist synovium in differentiation from activity to non-activity of rheumatoid arthritis (RA). Methods Ninety-two clinically confirmed RA patients underwent high frequency ultrasonography. Maximum thickness and arterial RI of the wrist synovium were measured in active and nonactive stage. Results Thickened synovium was found in 75 of 92 patients. Color signal in the synovium was detected and then RI was measured in 67 patients, including 31 in active stage and 36 in nonactive stage. The wrist synovium thickness of 67 patients was (2.97±1.49) mm and arterial RI was 0.74±0.17. RI decreased significantly in patients in active stage compared with that in nonactive stage (P<0.001). Conclusion Arterial RI measurement with high frequency ultrasonography may be served as an objective marker of synovial membrane disease in RA. The thickness of synovium cannot predict the activity of RA.

[ ABSTRACT] AIM:To cultivate stem-like spheres from SW620 cell line in the specific serum-free medium and evaluate the features of the cancer stem cells, and to investigate the effects of docosahexaenoic acid ( DHA) and eicosapen-taenoic acid ( EPA) on the growth of SW620 stem cell-like cells.METHODS: Human colon cancer stem cell-like cells ( CSCLC) were obtained from SW620 spheres cultured in serum-free medium.These cells were tested for the expression of SSEA-1 and TRA-1-81 by immunofluorescence staining.The mRNA expression of Sox-2 and Oct-4 was detected by real-time PCR.The efficiency of colony formation on a soft agar gel and tumor formation in the nude mice was compared between SW620 adherent cells and CSCLC.The inhibitory effects of 5-fluorouracil (5-FU) and mitomycin C on both types of cells were measured by MTS assay.MTS assay, Annexin V/PI staining and trypan blue staining were used to determine the effects of DHA and EPA on both types of cells.MTS assay was also used to analyze the combined effect of DHA or EPA with chemotherapeutic drugs on SW620 CSCLC.RESULTS:SW620 cells formed spheres in serum-free culture.The cells from spheres highly expressed SSEA-1 and TRA-1-81, transiently expressed Sox-2 and Oct-4 genes and were more resistant to 5-FU and mitomycin C treatments.These cells exhibited a greater ability in clone formation and tumorigenicity, indica-ting that these cells carried stem cell-like features, hence were considered SW620-derived CSCLC.DHA and/or EPA sup-pressed SW620 CSCLC by inhibiting cell growth, inducing cell apoptosis and sensitizing them to chemotherapeutic drugs. CONCLUSION:The cells with stem cell-like features, such as high efficiency in clonogenicity, tumorigenicity and resist-ance to chemotherapeutic drugs, can be obtained from SW620 spheres cultured in serum-free condition.DHA and EPA in-duce apoptosis in SW620-derived CSCLC and sensitize them to chemotherapeutic drugs.

Objective To investigate the effect of different HAART regimens on liver function,viral load and CD4+T cells of HIV infected children with HCV co-infection.Methods A total of 40 patients were divided into 4 groups:13 cases in AZT+3TC+NVP group(group A),16 cases in AZT+3TC+EFV group(group B),5 cases in D4T+3TC+EFV group(group C)and 6 cases in D4T+3TC+NVP group(group D).Liver function,viral load and CD4+T cells of patients in 4 groups were compared between before and after HAART.Results Eight patients(20％)had abnormal liver function before HAART treatment,and all of them had 1 level of liver damage.After receiving HAART,levels of ALT and AST were increased in group A and B(P<0.01);AST levels were increased in group C(P<0.01).CD4+T counts were all increased and HIV viral loads were decreased in 4 groups(P<0.01).There was no significant difference in RNA HCV load before and after HAART treatment(P>0.05).Conclusion Different HAART regimens can increase the liver damage in HIV infected children co-infected with HCV,but have little effect on the treatment efficiency of HAART regimens.
