Objective To observe the effect of Yiqi Huoxue decoction combined with chemical arterial perfusion in treating advanced pancreatic cancer. Methods Review the clinical effect and benefit response of Yiqi Huoxue decoction combined with chemicals (Gemcitabine+PDD) arterial perfusion in treating 43 cases of advanced pancreatic cancer. Results The objective response rate (CR+PR) in treated group was 25.6%. The clinical benefit response rate (CR+PR+NC) in treated group was 67.4%,and the clinical benefits were mainly in the aspects of pain extent and quality of life. The rate of relief from pain was 74.3%. Conclusion The effect of Yiqi Huoxue decoction combined with chemicals (Gemcitabine+PDD) arterial perfusion in treating advanced pancreatic cancer was reliable,and the clinical benefit response was good.

"Three-multi" overall evaluation system on the teaching effect of Microbiology experiment,which consisted of multi-aspect,multi-angle and multi-level,was discussed in this paper. The evaluation system showed a remarkable effect in stimulating the leaning interests of students especially.

By means of 3H-Thymidine and3H-Leucine incorporation, we observed that CGRP inhibited the multiplication of SHR's aortic smooth muscle cells (VSMCs) and the proliferation of VSMCs stimulated by Endothelin. These results suggest that CGRP may be a natu-ral antagonist of Endothelin in human body.

The amount of CD_3~+,CD_4~+ T cells and NK was obivously lower after treatment than before treatment in C group, and CD_8~+ T cells amount significantly increased after treatment compared with before treatment(P

Identification and functional analyses of antiviral restriction factors in hosts have become hot research topics. Four HIV restriction factors, APOBEC3G, Trim5alpha, Tetherin, and SAMHD1, have been identified in recent years. By encoding auxiliary proteins, lentiviruses can counteract host restriction factors. For example, the auxiliary proteins Vif, Vpu, and Vpx of HIV antagonize APOBEC3G, Tetherin, and SAMHD1, respectively. Furthermore, these auxiliary proteins enable the entry of HIV into host cells and influence the replication and pathogenicity of HIV. In this paper, we review the research progress in the functions of the three HIV auxiliary proteins that can antagonize the host restriction factors.

Objective To study the consistency in the diagnosis of preoperative TNM rectal cancer staging using high resolution magnetic resonance imaging (MRI) and transrectal ultrasound (TRUS) combined with carcinoembryonic antigen (CEA) and postoperative pathological TNM.Methods 156 cases pathologically proven were retrospectively analyzed and divided into 4 groups including preoperative MRI group (39 cases),TRUS group (39 cases),MRI and TRUS group (39 cases),MRI and TRUS combined with CEA group (39 cases).The differences between preoperative T,N staging and postoperative pathologic T,N staging were analyzed.Results There were statistically significant differences in the diagnosis of preoperative T and postoperative pathological T in 4 groups (T: Kappa =0.685,P =0.000; N: Kappa =0.544,P =0.000),but there were no significant differences in preoperative N and postoperative pathological N staging in preoperative MRI group,TRUS group,MRI and TRUS group (Kappa =0.142,P =0.329; Kappa =0.154,P =0.645; Kappa =0.154,P=0.229),and significant difference was observed in MRI and TRUS combined with CEA group (Kappa =0.544,P =0.000).There were no significant differences in the accuracy of T staging among the 4 groups (x2 =0.326,P =0.574; x2 =0.562,P =0.719; x2 =0.287,P =0.986),but significant difference in the accuracy of N staging were showed among the 4 groups (x2 =4.643,P =0.026; x2 =6.643,P =0.026; x2 =5.243,P =0.019).Conclusion Preoperative evaluation by the MRI add TRUS combined with CEA can improve the accuracy of preoperative staging,which can provide more reliable basis for decision-making and improve the coincidence rate of operative procedures in line with the estimate.It also provides the basis fur the accurate preoperative diagnosis and individualized treatment.

Based on the research of text (Ⅰ) which determined the fermentation medium, the fermentation condition of CNY086 including temperature, volume, inoculum and inoculum age had been studied by single factor and orthogonal experiment. The optimum temperature, liquid volume, inoculum and seed age were 15?C, 250 mL/500 mL, 15%, 10 h. Under the conditions above mentioned, enzyme activity reached 104.36 U/mL in 5 L fermentor.

21 cold-active strains which produced cold-active cellulase were isolated from Bohai Bay. One of the strains CNY01 was a kind of Trichoderma viride and its cellulase activity was 67.30 U/mL. Through UV and DES mutation, the strain CNY086 was bred and its cellulase activity was 92.17 U/mL. The strain CNY086 had stable ability to produce cellulase. Through orthogonal experiment, the optimal condition of the fermentation medium had been tested. The suitable medium was that straw power 1.20%, bran 0.70%, (NH4)2SO4 0.50%, KH2PO4 0.55%, in this condition the cellulase activity came to 108.55 U/mL.
