Fifteen journals related with liver diseases were selected from Chinese science and technology journal citation reports ( core ) ( CJCR ) during 2004 - 2009.Eleven important quantitative indicators including total cited frequency and impact factor were analyzed.At the same time,the dynamic evaluation model was also used to evaluate the academic influence of the 15 kinds of liver diseases journals.There were 5 kinds of trends:always arising,spiral arising,stabilizing after adjusting,vibrating highly and adjusting.The academic influence of liver diseases journals was rather high,but there were some problems including low academic influence,low ratio of funded papers and international papers and poor paper quality.

Objective To explore the correlation between axon guidance factor Semaphorin 5A and clinicopathological features and its role in the invasion and metastasis of gastric cancer.Methods The expression of Semaphorin 5A in gastric cancer tissues of 171 patients with different gender,age,histological type and TNM stage was detected with immunohistochemistry assay.The expression of Semaphorin 5A was determined by Western blotting assay in gastric cancer cell lines SGC7901 and MKN-45 with metastatic ability and gastric cancer cell lines SNU-1 and AGS without metastatic ability.With RNA interfere technique(RNAi),Semaphorin 5A siRNA expression vector was constructed and transfected into gastric cancer cell line SGC7901.The stable gastric cancer cell line down-expressing Semaphorin 5A was established.The effect of Semaphorin 5A gene silencing on the adhesion,migration and invasion of gastric cancer cell was examined by cell adhesion test,wound healing test and transwell chamber assays.Results The expression level of Semaphorin 5A was correlated with the differentiation degree of gastric cancer(x2 =6.32,P =0.01),lymphnode metastasis(x2 =7.68,P=0.01)and distant metastasis of gastric cancer(x2 =13.67,P =0.00),not correlated with age(x2 =0.21,P=0.79),gender(x2=1.79,P=0.15)and the depth of gastric cancer invasion(x2=1.34,P=0.55).The expression of Semaphorin 5A in cell lines SGC7901 and MKN-45 was significantly higher than that of cell lines SNU-1 and AGS(P＜0.01).Semaphorin 5A gene silencing significantly suppressed the adhesion,migration and invasion abilities of gastric cancer cells.Conclusion Semaphorin 5A may play a catalytic role in the invasion and metastasis of gastric cancer through increasing the adhesion,migration and invasion abilities of gastric cancer cell.

Objective:To evaluate dendritic cells induced immune response against hepatocellular carcinoma by pulsed CD34+ hematopoietic stem cells originated dendritic cells with p53 gene.Methods:CD34+ hematopoietic stem cells were harvested after mobilization by chemotherapy and G-CSF.CD34+ hematopoietic stem cell apheresis was induced to differentiate into dendritic cells by cytokine cocktail IL-4,GM-CSF and TNF-?.On day 7,dendritic cells were transfected with plasmid pEGFP-C3/p53 DNA.The CTL response triggered by p53 pulsed dendritic cells was assayed by MTT method.Results:Dendritic cells originated from CD34+ cell apheresis had typical dendritic stick and expressed high level CD1a,CD11c,CD80,CD86,and HLA-DR molecules.After being pulsed with p53 gene,dendritic cells expressed green fluorescence protein and immunofluorescence assay(Cy3 labeled anti-P53 antibody)showed that transfected dendritic cells emitted red fluorescence.Dendritic cells inducing CTL response against HMCC97 cells(P53 positive)and HepG2 cells(P53 negative)were assessed by MTT method.P53 pulsed dendritic cells could induce P53 specific immune response against HMCC97 cells and the cytotoxin rate was(49.3?4.6)% compared with pEGFP-C3 transfection group [(25.4?4.1)%] and control group[(24.8?3.8)%](P0.05).Conclusion:P53 gene transfecting hematopoietic stem cell apheresis originated dendritic cells could induce specific CTL response against P53-expressing hepatocellular carcinoma cells.P53 may be a potential candidate for dendritic cell based immunotherapy of cancer.

Objective: To investigate the association between the CYP3A5 genetic polymorphism and the serum concentrations of carbamazepine (CBZ), to provide guidance for individualized drug dosing. Methods: Eighty-four epilepsy patients taking CBZ were included in this study. Their clinical data were recorded and CBZ serum concentrations were measured. The CYP3A5 6986 genetic polymorphism was assessed using a polymerase chain reaction-restriction fragment length polymorphism (PCRRFLP) assay. Patients were divided according to genotype into CYP3A5 expressor (CYP3A5*1/*1 genotype and CYP3A5*1/*3 genotypes) and non-expressor groups (CYP3A5*3/*3). The two groups were compared for the total dose of CBZ, dose of CBZ/kg body weight, serum drug concentration, dose-corrected serum concentration, and standardized serum concentration. Results: The total dose of CBZ and the dose of CBZ/kg body weight was higher in the CYP3A5 expressor group than the non-expressor (P = 0.043 and P = 0.014, respectively). The dose-corrected and standardized serum concentrations were lower in the CYP3A5 expressor group than the non-expressor (P = 0.001 and P < 0.001, respectively). There was however, no signifi cant difference in serum drug concentration between the two groups (P = 0.487). Conclusions: There was a close relationship between CYP3A5 genetic polymorphism and the serum concentrations of carbamazepine.

In order to control the quality of all parts of the process for culturing,preparing and using clinically the human embryo olfactory ensheathing cells (OECs),the conduct standard of culturing human OECs from olfactory bulb is formulated. Because the strict conduct process can reduce the human factor as much as possible and ensure the stability of the cell quality. Therefore,during the culturing process of human embryo OECs, as for the embryo sample of OECs from olfactory bulb,the standard of lab condition and cell culture must be set strictly. The key steps of conduct process must be regulated,the freezing and resuscitating process of OECs must be controlled,the test method for microbial contamination during cell culture must be proposed and the risk must be reduced,then the quality of the human OECs from olfactory bulb can be guaranteed during the clinical application.

The aim of this project is to establish a fibroblast growth factor-21 (FGF-21) signaling pathway targeted cell model, for screening a class of FGF-21 receptor agonists as anti-diabetic candidates. FGF-21 requires beta klotho transmembrane proteins as co-receptor for the activation of tyrosine kinase FGF receptor (FGFR) signaling, thereby activating a series of intracellular signaling pathways and regulating gene transcription for glucose metabolism. Firstly a recombinant plasmid expressing co-receptor beta klotho and EGFP reporter genes was constructed. After introducing the recombinant plasmid into package cells, the cell culture supernatant was used to infect 3T3-L1 cells, which were then screened for stably expressing beta klotho gene. Administration of FGF-21 increased the expression of GLUT1 and stimulated GLUT1-mediated glucose uptake. This novel cell model can be conveniently used in high-throughput drug screening of FGF-21 or FGF-21 analogues.

FGF21 (fibroblast growth factor 21) is a recently described member of the FGF family. It has been previously demonstrated that FGF21 is a potent regulator of glucose homeostasis. To improve stability of FGF21 for better efficacy, a new form of recombinant FGF21 was generated by fusion of a full length FGF21 gene and the Fc fragment of human IgG4 with flexible linker sequence. To examine the glucose regulation activity of FGF21-L-Fc, 3T3-L1 pre-adipocytes were differentiated into adipocytes, and glucose uptake activity of FGF21-L-Fc was examined by glucose oxidase and peroxidase (GOD-POD) assay. The results showed that in comparison with wild type FGF21, FGF21-L-Fc was more potent in stimulation of glucose uptake by 3T3-L1. In vivo studies on the modified protein demonstrated that FGF-L-Fc had a better efficacy in lowering blood glucose of the STZ-induced diabetic animals and controlled glucose level for a longer time. The results provided a sound basis for further studies.

Objective To evaluate the anxiety and depression problems in children parents with leukemia, as well as the problems' influence to the psychosocial characteristics of leukemia children.Methods Twenty long-term survivors of childhood leukemia (group A), thirty children newly diagnosed as leukemia (group B) and fifty age-matched healthy controls (group C) completed the questionnaires allowing assessment of symptoms associated with anxiety, depression and self-concept. At the same time, the anxiety and depression in the parents of children with leukemia were also measured using SAS and SDS. Results The anxiety and depression scores of the parents in study group (48.56±9.23, 51.86±9.53) were much higher than that in normal population (37.23±12.59, 41.88±10.57) (P = 0.000, 0.000, respectively), the positive rate of anxiety and depression symptoms among group B was significantly higher than that among group A (60.0 % vs 25.0 %, 46.7 % vs 20.0 %; P <0.05, respectively). There was a significant positive relation between the depression and anxiety scores in the parents of children with leukemia(r =0.947, P =0.0000). Group A scored significantly higher on subscales of somatization/panic (6.11 ±4.36), generalized anxiety (5.72±4.56),social phobia (7.67±4.19) and the total scale (25.8±13.98) than group C (the score was 3.68±3.39, 2.54±2.99,4.24±2.88 and 15.9±10.52, respectively) (P<0.05, respectively), group B scored significantly higher on subscales of social phobia (6.03 ±2.16) than group C (4.24±2.88) (P =0.016). There was a significantly positive relation between the depression score in children with leukemia and the anxiety (r = 0.309, P = 0.029) & depression(r = 0.342, P = 0.015) scores in their parents. Group A scored significantly higher on the total score of self-concept(60.8±6.25) as well as the subscales of happiness(7.95±1.32) than group G (64.48±7.89 vs 8.64±1.19) (P =0.039, 0.026, respectively); and group B scored significantly higher on subscales of behavior (12.47±1.25), intelligence(10.80±2.12), physical appearance and attributes (8.40±2.66), anxiety (9.93±1.29) and the total scale (59.83±5.87) than group C (14.00±2.17, 12.60±2.96, 9.64±2.30, 11.38+2.18, 64.48±7.89) (P <0.05, respectively). There was a significantly positive relation between the score of gregarization subscale in leukemic children and the anxiety score in their parents (r = 0.337, P = 0.017). Conclusion The findings of our studies have suggested that the parents of children with leukemia are at risk for psychological difficulties, and which have a great influence on the psychological health of their children.

Objective Acute kidney injury (AKI) frequently occurs after catheter-based interventional procedures and increases mortality. How-ever, the implications of AKI before thoracic endovascular aneurysm repair (TEVAR) of type B acute aortic dissection (AAD) remain un-clear. This study evaluated the incidence, predictors, and in-hospital outcomes of AKI before TEVAR in patients with type B AAD. Meth-ods Between 2009 and 2013, 76 patients were retrospectively evaluated who received TEVAR for type B AAD within 36 h from symptom onset. The patients were classified into no-AKI vs. AKI groups, and the severity of AKI was further staged according to kidney disease:im-proving global outcomes criteria before TEVAR. Results The incidence of preoperative AKI was 36.8%. In-hospital complications was significantly higher in patients with preoperative AKI compared with no-AKI (50.0%vs. 4.2%, respectively;P<0.001), including acute renal failure (21.4%vs. 0, respectively;P<0.001), and they increased with severity of AKI (P<0.001). The maximum levels of body tem-perature and white blood cell count were significantly related to maximum serum creatinine level before TEVAR. Multivariate analysis showed that systolic blood pressure on admission (OR:1.023;95%CI:1.003–1.044;P=0.0238) and bilateral renal artery involvement (OR:19.076;95%CI:1.914–190.164;P=0.0120) were strong predictors of preoperative AKI. Conclusions Preoperative AKI frequently oc-curred in patients with type B AAD, and correlated with higher in-hospital complications and enhanced inflammatory reaction. Systolic blood pressure on admission and bilateral renal artery involvement were major risk factors for AKI before TEVAR.
