Objective To observe the clinical efficacy of Jianpi Huatan Decoction plus Zhongwan (RN12) moxibustion on patients of mild to moderate stable chronic obstructive pulmonary disease (COPD) with syndrome of qi deficiency of lung and spleen, and analyze the related influencing factors. Methods With prospective randomized clinical trial, 140 cases of mild to moderate stable COPD were randomized into two groups (70 cases for each group). Treatment group was treated by Jianpi Huatan Decoction plus Zhongwan moxibustion based on western medicine, and control group was only treated by western medicine. Both groups were treated for 12 weeks and followed up for 12 weeks. Scores of clinical symptoms and quality of life questionnaire were examined, and multiple logistic regression analysis was used to find possible impacting factors on the effect. Results Symptoms were significantly alleviated after treatment (P<0.01) in both groups. The clinical effects and quality of life in treatment group were significantly improved than the control group (P<0.01). There were no significant changes in life quality of control group ( P>0.05). Multiple logistic regression analysis showed that different therapies and severity of COPD were the major influencing factors of clinical effect (P<0.05, P<0.01). Conclusion Jianpi Huatan Decoction plus Zhongwan moxibustion had significant therapeutic effect on mild to moderate stable COPD patients with syndrome of qi deficiency of lung and spleen by alleviating symptoms and improving quality of life. Treatment style and severity of COPD are the main influencing factors.

ObjectiveTo generate a prokaryotic expression system of series predominant epitopes (UreB322 and UreB527) of Helicobacter pylori UreB protein,and to synthesize a multiple antigenic peptide (MAP) vaccine by linking both the two epitopes with a peptide carrier (Poly-Asp-Lys),and to determine the immunogenicity and immunoprotection of the MAP vaccine.MethodsLinking primer PCR was performed to generate an enterokinase(EK) site-containing series UreB322 and UreB527 epitope encoding gene for construction of its prokaryotic expression system.The expressed target recombinant fusion protein 8 ×[rEK-UreB322-EK-UreB527-EK] was hydrolyzed with EK and then rUreB322-EK and rUreB527-EK epitope peptides were extracted using a Sephadex G-25 column.rUreB322-EK,rUreB527-EK and Poly-Asp-Lys were linked using carbodiimide method to produce a MAP vaccine (MAP-rUreB322/B527).The antigenicity and immunoreactivity of each of the two epitope peptides and MAP-rUreB322/527 were determined by ELISA and Western blot assay.An animal H.pylori strain SS1-infected model in BALB/c mice was used to detect the immunoprotection of MAP-rUreB322/527.ResultsAn octuple-repeated series UreB322-UreB527 encoding gene and its prokaryotic expression system were obtained.The yield of target fusion protein 8×[rEKUreB322-EK-rUreB527-EK] was as high as 48％ of the total bacterial proteins.EK hydrolyzed the target fusion protein completely into rUreB322-EK and rUreB527-EK peptides.The linking ratio of rUreB322-EK,rUreB527-EK and Poly-Asp-Lys was as high as 92.5％.The antibody against whole cell of H.pylori and rUreB-IgG could recognize and combine with the rUreB322-EK,rUreB527-EK or MAP-rUreB322/527.The specific serum antibody level in MAP-rUreB322/527-immunized mice was significantly higher than that in rUreB-immunized mice (P＜0.05).The immunoprotective rates(83.3％ and 91.7％ ) by immunization with50 or 100 μg MAP-rUreB322/527 in the H.pyloristrain SSI-infected mice were significantly higher that those(d1.7％ and 50.0％ ) by immunization with equal rUreB(P＜0.05).ConclusionAn gene composed for encoding a repeated series predominant epitopes of H.pylori UreB protein and its prokaryotic expression system are successfully generated in this study.MAP-rUreB322/527,the multiple antigenic peptide vaccine based on the two predominant epitopes of UreB,can noticeably increase the immunoprotection in H.py/or/infected mice.

Tripterygium wilfordii has exihibited multiple pharmacological activities, such as anti-inflammatory, immune modulation, anti-tumor and anti-fertility. T. wilfordii have been used for the therapy of inflammation and autoimmune diseases including rheumatoid arthritis, immune complex nephritis and systemic lupus erythematosus clinically. However, it is well known that T. wilfordii has small margin between the therapeutic and toxic doses and could cause serious injury on digestive, reproductive and urogenital systems. Among all the organs, liver is one of the most remarkable targets of T. wilfordii-induced toxicities, and the damage is more serious than others. It is generally accepted that T. wilfordii-induced liver injury is a result of the combined effects of toxic elements of T. wilfordii. It is reported in several studies that the mechanism of T. wilfordii-induced liver injury may be related to lipid peroxidation, cell apoptosis and immune damage, and so on. Licorice is one of the most commonly used Chinese herbal medicine, with effects of heat- clearing and detoxicating, anti-inflammatory and hepatoprotective, reconciling various drugs, and so on. Licorice often accompany T. wilfordii in clinical application which can significantly reduce the liver injury induced by T. wilfordii. The attenuated effect is exact, but the mechanism is still a lack of in-depth study. This paper reviews the studies on T. wilfordii-induced liver injury and the related mechanism as well as licorice and other traditional Chinese medicine accompany T. wilfordii to reduce the injury in recent years, so as to provide reference for related research in the future.

Aim To establish and optimize the VSVG/HIV-1NL4-3 Luc pseudovirus model for anti-HIV drugs screening. Methods The infectivity of VSVG/HIV-1 NL4-3 Luc in 4 different cell lines was investigated according to the method of the lucifer-ase activity analysis system of Promega company. 3 different ex-perimental settings were used to detect the activities of approved anti-HIV drugs to confirm the feasibility and effectiveness of the system. Finally, some potential compounds were screened for their anti-HIV activities, and their antiviral activities against the pseudovirus were compared with HIV-1ⅢB . Results The pseud-ovirus showed the strongest replication ability in CRFK cells, and a clear dose-effect relationship was found between the report gene expression level and the virus quantity. Comparing the EC50 of different positive inhibitors against VSVG/HIV-1 NL4-3 Luc on 3 kinds of experimental conditions, 3rd scheme is the best. Finally, the system was used to screen compounds, the EC50 s a-gainst pseudovirus were similar to those in HIV-1ⅢB . Conclusion An optimized VSVG/HIV-1 NL4-3 Luc anti-HIV screening sys-tem has been successfully developed.
