Objective To explore a reasonable therapeutic plan for treating HIV/AIDS with traditional Chinese medicine plus western medicine. Methods Twenty-nine patients with HIV/AIDS were selected and recruited into a HIV group and a AIDS group according to the clinical diagnosis. Each group was further divided into comparison stage and treatment stage. In HIV group, observations and statistics of observation indexes were performed during the comparison stage; while TCM treatment was applied in the treatment stage. In AIDS group, HAART was applied in the comparison stage, and HAART combined with TCM therapy were used in the treatment stage. Both comparison stage and the treatment stage lasted 12 months. Results In HIV group, self control results showed that immune and virus indexes did not have significant changes, but also with no side or toxic effects, In the AIDS group, contrasting between the comparison stage and the treatment stage showed that there were significant improvement of symptoms (χ2=4.9231, 2.5000, P<0.05) , anti-toxic effects (χ2=9.333、 16.4091、10.2273, P<0.01) and immune indexed(t=3.1990,P<0.01) after treated additionally with traditional Chinese medicine. Conclusion Traditional Chinese medicine could improve the immunity function and clinical symptoms, reduce side effect of HAART medicine and stabilize CD4+ T cells of patient with HIV/AIDS.

Objective To over-express human trefoil factor 2 (hTFF2) by Escherichia coli system and an-alyze its activities in promoting migration and anchorage-independent growth in SW480 colonic cancer cells. Meth-ods hTFF2 gene encoding mature peptide was obtained by RT-PCR, and the recombinant expression vector pET32a-hTFF2 was constructed. Then pET32a-hTFF2 was transformed into E. coli BL21-32a and TrxA-hTFF2 fu-sion protein was induced to over-express. The expressed product was isolated by Ni-NTA affinity chromatography, purified by dialysis and identified by Western blotting. The activities of the recombinant hTFF2 in promoting SW480 cells migration and anchorage-independent growth were analyzed by MicroChemotaxis Chamber migration assay and Soft-agar assay,respectively. Results The TrxA-hTFF2 fusion protein was expressed to 220 mg/L at high purity. In vitro model demonstrated that recombinant hTFF2 obviously enhanced SW480 cell migration activity and anchor-age-independent growth. Conclusion The recombinant hTFF2 can be expressed in E. coli with high production, purity and biological activities. And its roles in cell migration and anchorage-independent growth suggest that up-regulation of TFF2 in colonic cancer might be involved in cancer invasion and metastases.

Objective To study the expression profile of microRNA (miRNA) and the roles in pathogenesis of acute liver failure in mouse model. Methods Eighty-five BALB/c mice were divided into four groups: 40 in model group of acute liver failure were intraperitoneally injected with Dgalactosamine (D-GalN) and lipopolysaccharides (LPS); 20 in D-GalN group were injected with DGalN only; 20 in LPS group were injected with LPS only; 5 in control group were injected with saline.Liver histology of mouse was observed at hour 0, 5, 7 of injection, and sera and liver tissues were collected at hour 0, 1, 3, 5, 7, 9 of injection. Meanwhile, levels of inflammatory factors [tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6)] in serum and liver tissue were detected by realtime polymerase chain reaction (PCR). Lock nucleic acid (LNA)-based miRNA microarray technology was used to detect the expression profile of hepatic miRNA, and the expression of miRNA was verified by real time quantification-polymerase chain reaction (RT-PCR). Mouse macrophage Raw264.7 cells were induced by LPS in vitro and the expressions of miRNA at different time points were detected.The comparison of means among groups was analyzed using one way ANOVA and the correlation were analyzed by Pearson and Spearman correlation. Results Microarray analysis found that the expression profile of miRNA during the acute liver failure changed dramatically. There were 97 miRNA in model group changed significantly compared with control group (P<0.01), including 21 up-regulated and 27down-regulated at hour 5 and 7 of injection. Furthermore, the expressions of miR 146a and miR-155were verified by RT-PCR and found they both increased progressively over time after injection.Correlation analysis showed that miR-155 was well correlated with both TNF-α and IL-6 expressions.It was further found that miR-146a and miR-155 were both up-regulated in activated Raw264.7 cells in vitro. Conclusions The expression profile of miRNA changes during acute liver failure in mouse model. Inflammation associated-miR-146a and miR-155 are both up-regulated significantly, which indicatcs that they may play an important regulatory role in pathogenesis of acute liver failurc.

To identify the related substances of fusidic acid by LC-MS,separation was performed on an Agilent Extend-C18column(150 mm ×4. 6 mm,3. 5 μm)by linear gradient elution with a mobile phase consisting of methanol,acetonitrile and formic acid. Electrospray positive ionization high resolution TOF/MS was used for the determination of the accurate mass and elemental composition of parent ions of the related substances;triple qua-drupole tandem mass was employed for the mass spectra determination of the product. The structures of the related substances were then figured out through the elucidation of the fragment ions. Fusidic acid and its related sub-stances were adequately separated under the established HPLC conditions. Nineteen major related substances of fusidic acid were detected and speculated by hyphenated techniques. Eleven of them were recorded in European Pharmacopoeia,while the others have not been previously reported. The established LC-MS method is effective for the separation and identification of the related substances of fusidic acid and the results are useful for its storage conditions and quality assurance.

Ankylosing spondylitis(AS)is a typical spinal arthritis characterised by inflammatory back pain,which seriously affects the health and quality of life of patients.The clinical efficacy of Chinese medicine in the treatment of ankylosing spondylitis is clear,but the mechanism is not clear,and the existing animal models cannot be well applied to the evaluation of Chinese medicine in the treatment of ankylosing spondylitis.Therefore,this paper summarizes the existing animal models based on Chinese and Western medicine clinical diagnosis,disease characteristics,etiology and Chinese medicine evidence,and finds that among the existing animal models,the proteoglycan-induced arthritis mouse model has a higher Chinese and Western medicine clinical fit than the other models,but lacks the corresponding Chinese medicine evidence model evaluation.The other animal models had a higher Western clinical match,but lacked the characteristics of the Traditional Chinee Medicine(TCM)syndrome.As ankylosing spondylitis is a chronic inflammatory autoimmune disease with complex pathogenic factors,the existing animal models cannot better simulate the clinical symptoms.Therefore,the establishment of animal models of ankylosing spondylitis with the characteristics of Chinese and Western clinical evidence is a future research priority for AS TCM.
