Objective To study the effect of flow-restricted arterio-portal shunt(APS)on the liver.Methods Experimental model of APS and flow-restricted APS were reproduced in rats,and its effects on hepatic blood flow(HBF)and portal venous pressure(PVP)were observed,and the changes in liver structure were investigated six months after the operation.Results Compared with that of pre-operation,both HBF and PVP in APS group at the sixth month after operation changed significantly(P0.05).The PVP changed significantly(P0.05).No obvious lesions were found in the liver by histological examination.Significant differences of both PVP and HBF were found at the sixth month between the two groups(P

To develop an effective therapeutic HBV DNA vaccine, two eukaryotic expressing plasmids, namely pcDNAS 2 ?S and pcDNAIIF , which respectively encoding HBV middle envelope protein preS 2 ?S and human IL 2/IFN ? fusion protein, were constructed by DNA recombinant technique. After identification by restriction analysis and DNA sequencing, the constructed recombinant plasmids were transfected into COS 7 cells in vitro with transfection reagent Lipofectamine. The expressed product in supernatant was quantified by ELISA , and the biologic activities of IL 2 and IFN ? were assayed by CTLL 2 cell line proliferation and cytopathogenic inhibition, respectively. The results showed that secretive expression of preS 2 ?S and hIL 2/hIFN ? fusion protein peaked at 48h after transfection, and the expression levels were HBsAg(P/N)=7 63, IL 2=10 35ng/ml, and IFN ?=7 90ng/ml. The IL 2 and IFN ? activities in the culture supernatant of COS 7 cells transfected with pcDNAIIF were 998U/ml and 249U/ml, respectively. These results suggested that the recombinant plasmids pcDNAS 2 ?S and pcDNAIIF were correctly constructed and the transfected cells could express secretive active protein.

Traditional Chinese medicine (TCM), an important component of complementary and alternative medicine, has evolved over thousands of years with its own unique system of theories, diagnostics and therapies. TCM has been increasingly used in the last decades and become well known for its significant role in preventing and treating cancer. We believe that TCM possesses advantages over Western medicine in specific aspects at a certain stage of cancer treatment. Here we summarize the advantages of TCM from three aspects: preventing tumorigenesis; attenuating toxicity and enhancing the treatment effect; and reducing tumor recurrence and metastasis.

Objective To obtain the sequence of recombinant human basic fibroblast growth factor (rhbFGF) with endonuclease sites of BamHI and Pst Ⅰ by PCR based gene assembly and construct the recombining vector of rhbFGF gene by TA cloning technique.Methods The rhbFGF gene sequence which was designed for lactococcus with endonuclease sites of BamHI and Pst Ⅰ was divided into 22 oligonucleotides by DNASTAR 6.0 (bFGFl-bFGF22).The 22 oligonucleotides were spliced by PCR based gene assembly to get the rhbFGF eDNA with endonuclease sites of BamHI and Pst Ⅰ.The PCR product was inserted into the PMD18-T VECTOR.The recombining vector were converted to the competent E.coli TOP10.The clones generated from LAB were analyzed by miniprep isolation from LAB host.They were identified by the restriction enzyme cuuing and sequencing.Results The rhbFGFcDNA synthesized by PCR based gene assembly with endonuclease sites of BamHI and Pst Ⅰ was verified by 2％ agarose electrophoresis.The recombining vector of rhbFGF gene by TA cloning technique was identified by enzyme digestion and gene sequencing.Conclusions The TA cloning vector of recombining hbFGF with endonuclease sites of BamHI and Pst Ⅰ was constructed successfully.

Neuron is the basic unit of the biological neural system. The Hodgkin-Huxley (HH) model is one of the most realistic neuron models on the electrophysiological characteristic description of neuron. Hardware implementation of neuron could provide new research ideas to clinical treatment of spinal cord injury, bionics and artificial intelligence. Based on the HH model neuron and the DSP Builder technology, in the present study, a single HH model neuron hardware implementation was completed in Field Programmable Gate Array (FPGA). The neuron implemented in FPGA was stimulated by different types of current, the action potential response characteristics were analyzed, and the correlation coefficient between numerical simulation result and hardware implementation result were calculated. The results showed that neuronal action potential response of FPGA was highly consistent with numerical simulation result. This work lays the foundation for hardware implementation of neural network.
