Objective To discuss the value of hypotonic-MRCP combined with LAVA dynamic contrast-enhanced scan in diagnosis of duodenal tumor.Methods Five patients with duodenal adenocarcinomas confirmed by pathology were involved in this study.All cases underwent plain MRI and hypotonic-MRCP and LAVA dynamic contrast-enhanced scans.Results 4 of 5 cases were correctly diagnosed with MR imaging.Imaging signs included:the cavum of descending duodenum appeared as asymmetrical stenosis,masses with soft tissue signal intensity connecting the intestinal wall with wide base,the intestinal wall stiff,the intestinal mucosa destruction.The lesions would be slightly-moderately enhanced at LAVA dynamic enhancement scanning.Conclusion Hypotonic-MRCP combined with LAVA dynamic contrast-enhanced scan can display the direct and indirect sign of duodenal tumors,which was effective in identifying the circumscription of the tumor and its extension.

Background and purpose:Drug-resistance is the main obstacle in terms of efficacy of chemotherapy for leukemia, RNA interference(RNAi) strategy possesses the characteristics of specilization, high-efficiency and low-toxicity, and can effectively and specifically inhibit the overexpression of given gene. This study was designed to investigate the effect of small interfering RNA (siRNA) on expression of mdr1 gene and drug-resistance in multidrug-resistant human leukemia K562/ADM cell.Methods:Human multidrug-resistant leukemia cell line K562/ADM over-expressing mdr1 gene was used as the target cells, Two siRNAs (si-mdr1-1 and si-mdr1-2) targeted mdr1 gene were chemically synthesized and transfected into K562/ADM cells. Expression of mdr1 mRNA was determined by RT-PCR, P-glycoprotein (P-gp) expression was measured using flow cytometry (FCM), and the sensitivity of K562/ADM cells to adriamycin was assessed with a MTT colorimetric assay.Results:Two siRNAs (si-mdr1-1 and si-mdr1-2) specially designed in this study could markedly down-regulate the expression of mdr1 mRNA and its product P-gp in K562/ADM cells. After cells transfected with si-mdr1-1 or si-mdr1-2 for 24h and 48h, the inhibition of mdr1 mRNA expression in the cells for si-mdr1-1 was 55.5% and 22.5%; and for si-mdr1-2, 16.0% and 57.6%, respectively. Treated with siRNA for 72h, the expression intensity of P-gp in the two transfected cell lines decreased 74% and 85%, respectively. Both si-mdr1-1 and si-mdr1-2 significantly enhanced the sensitivity of K562/ADM cells to adriamycin and reversed their drug-resistance, the reversal efficiency was 2.52-folds and 1.96-folds, respectively.Conclusions:The siRNA could effectively and specifically silence the expression of mdr1 gene and overcome the drug-resistance mediated by P-gp in K562/ADM cells.

Facing current situation of integrative medicine (IM), authors put forward that clinical and diagnosis program of IM could be carried out from clinical path, pathogenesis, treatment theory and philosophy, and so on, but with different integration degrees. Meanwhile, formulation of concrete program should be disease-targetedly set up, and adjusted from person to person, from place to place, from time to time. As for settled IM program , authors could evaluate it from whether Chinese medicine and Western medicine have formed complementary, synergistic, excitatory actions, and toxicity attenuation; whether more problems could be solved in efficacy, safety, practicability, and economy than previous single mode.

Objective:To construct a DNA vaccine co-expressing the HBV compound multi-epitope antigen gene, the hIL-12 and the anti-HBV siRNA genes, and to express this DNA vaccine in HepG2 cells. Methods:The HBV multi-epitope antigen gene was designed and synthesized before it was fused with enhanced green fluorescent protein(EGFP) gene, and cloned into the multi-clone site(MCS) of the eukaryotic expression vector pVAX1. The expressinig units of hIL-12 and siRNA were cloned into the BspH I and Mlu I site of pVAX1 respectively. Then the recombinant plasmid pVAX1-siHBV-HB-EGFP-hIL12 was transiently transfected HepG2 cells. The expression of HBV compound multi-epitope gene was observed through EGFP report gene. The expression of hIL-12 was analyzed by ELISA and the effects of anti-HBV siRNA was confirmed with rtPCR . Results: The analysis of enzyme digestion and sequencing both demonstrated that the trible-expressing HBV DNA vaccine has been constructed successfully. The green fluorescent image was detected in the transfected cells which could confirm the expression of the multi-epitope antigen gene. The amount of hIL-12 secretion was 1289pg/ml in supernatant at 48h after transfection and 1712pg/ml at 72h after transfection. The mRNA amount of HBV S gene, which was the siRNA target, had been obviously knockdown. Conclusion: The DNA vaccine co-expressing the HBV compound multi-epitope antigen gene, the hIL-12 and the siRNA genes was constructed and transiently expressed in HepG2 cells, and siRNA had shown us a good anti-HBV effect. It laid a foundation of further study on anti-HBV effect of the new DNA vaccine.

Proteomics is an emerging discipline developed on the basis of genomics.The fundamental techniques of proteomics include sample preparation,protein separation,protein identification and analysis,and its core techniques are two-dimensional gel electrophoresis and mass spectrometry.In recent years,proteomics has been used in researching the field of Mycobacterium tuberculosis(MTB).Proteomics promotes deep understanding of the pathogenesis of MTB and resistance mechanism via isolating,identifying and analyzing the whole-cell protein and secreted proteins.The development of new vaccine against MTB has showed some promising results based on proteomics.Some powerful early diagnostic markers have been discovered via analyzing the protein composition of MTB clinical isolates.Proteomics also applies to find potential new drug targets,and it has shown many valuable research productions in developing new an-ti-MTB drugs.In summary,the application of proteomics has built a solid foundation for the development of prevention,early diagnosis and treatment of tuberculosis.
