Objective To clone and bioinformatically analyze the full-length sequence of F protein binding protein 1 (FBP1). Methods Yeast two-hybrid system was employed to obtain an unknown gene and named it as FBP1.The coding sequence of FBP1 was cloned using molecular biological techniques. Results The coding sequence of FBP1 was cloned successfully. Conclusion FBP1, a cellular protein binding to F protein of HCV, plays an important role in the interaction of virus protein and host cell protein.

Background Recombinant hirudin variant Ⅲ(rHV3) can effectively prevent galactose-induced human lens epithelial cells LECs injury,but little is known about the molecular mechanism of its action.Objective The present study was to investigate the effects of rHV3 on the expression of apoptosis-related genes in damaged LECs induced by galactose.Methods The rHV3 was extracted by our research group,and the biological activity of rHV3 was identified by titration of thrombase according to Markwardt's method.Human LECs (SRA01/04) were cultured using 125×10-3 mol/L D-galactose+10% FBS+D/F12 medium to establish the damaged human LECs model.rHV3 was added into the medium of the damaged human LECs model.Human LECs were cultured in D/F12 medium containing 10% FBS as normal control.The expression of apoptosis-related genes,such as aldose reductase (AR),bax,bcl2 and p53,in LECs at the mRNA level was detected using RT-PCR.The abundance ratio of target genes was presented with the absorbance (A) of gene mRNA/GAPDH mRNA.Results Compared to the normal control group,the A values of AR mRNA/GAPDH mRNA,bax mRNA/GAPDH mRNA and p53 mRNA/GAPDH mRNA were significantly elevated in model group (t=3.90E-06,t=8.44E-04,t=5.15E-08,P<0.01).However,in the rHV3-treated group,the A values of AR mRNA/GAPDH mRNA,bax mRNA/GAPDH mRNA and p53 mRNA/GAPDH mRNA were lower than those of model group (t=5.90E-06,t=1.51E-04,t=3.42E-06,P<0.01).The bcl2 mRNA/GAPDH mRNA was markedly downregulated in the model group when compared with the normal control group (t=1.86E-05,P<0.01);while after rHV3 addition,bcl2 mRNA/GAPDH mRNA increased in comparison with the model group (t=8.56E-05,P<0.01).Conclusion 125×10-3mol/L D-galactose induces the damage and apoptosis of human LECs.rHV3 likely plays a protective function on D-galactose-induced damage of human LECs by inhibiting the polyol pathway and mitochondria-mediated pathway.

OBJECTIVETo observe the clinical effect of Chinese medical (CM) syndrome differentiation based Chinese herbs and recombinant human tumor necrosis factor receptor II-antibody fusion protein (etanercept) for treating ankylosing spondylitis (AS) patients.
METHODSTotally 35 AS patients were treated with syndrome differentiation based Chinese herbs and etanercept. Reinforcing Shen and strengthening Du channel, activating meridians to stop pain was principle used in syndrome differentiation based treatment. Etanercept was subcutaneously injected, 25 mg each time; twice per week for the first three months and once a week for the latter three months. The clinical efficacy was evaluated after 3 and 6 months of treatment. Meanwhile, ASAS20 and ASAS50 standards arriving rates were also observed. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), visual analog score (VAS) for spine pain, VAS for night pain, patient global assessment (PGA), VAS for physician global assessment, CM syndrome score, finger-ground distance, thoracic activity, tragus-wall distance, lumbar scoliosis, cervical rotation, Schober improved test, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were observed before treatment, 3 and 6 months after treatment.
RESULTSCompared with before treatment, BASDAI, BASFI, VAS for spine pain, night pain, physician global assessment, PGA, CM syndrome score, finger-ground distance, thoracic activity, tragus-wall distance, lumbar scoliosis, Schober improved test, ESR, and CRP all decreased after 3 and 6 months of treatment, with statistical difference (P < 0.05). Cervical rotation also decreased after 6 months of treatment, with statistical difference (P < 0.05). Compared with 3 months of treatment, total effective rate of CM syndrome, ASAS20 and ASAS50 standards arriving rates increased after 6 months of treatment, with statistical difference (P < 0.05). There were statistical differences in all indices mentioned above between after 3 months of treatment and after 6 months of treatment (P < 0.05).
CONCLUSIONSyndrome differentiation based Chinese herbs combined etanercept could alleviate inflammatory reaction favorably, control the progression of active AS, and improve joint functions.

Objective To explore the change of serum osteopontin levels in preoperative and postoperative patients with non-small cell lung cancer (NSCLC) and its clinic significance.Methods The levels of serum osteopontin were detected by ELISA.Results In 88 NSCLC patients,serum osteopontin levels were significantly higher than in benign pulmonary disease and healthy control group(P<0.05.P<0.01.respectively) There was no difference between benign pulmonary disease and healthy control group(P>0.05).Serum osteopontin levels were related to clinical stage and lymph node metastasis,and the levels of serum osteopontin were lower in postoperative patients than in preoperative cases(P<0.05).For NSCLC.the detection of osteopontin had a sensitivity of 84.1%,a specificity of 92.5%,and an accuracy of 88.1%. Conclusion Increased serum levels of osteopontin may be useful as a helpful clinical biomarker to diagnose earlier,predict prognosis and differentiate from benign pulmonary disease.
