HPLC fingerprint of Congrong Zonggan capsule was established in order to provide basis for quality evaluation. With acteoside as the reference, HPLC was adopted for fingerprint analysis on Congrong Zonggan capsule. The chromatographic conditions wereas follows. Waters C18 column (4.6 mm x 150 mm, 5 μm) was used, with methylalcohol-0.1% formic acid as the mobile phase for gradient elution at the flow rate of 1.0 mL x min(-1). The detection wavelength was 330 nm, and the column temperature was 30 °C. This method was highly accurate and reproducible. All of the 13 components in tested samples reached the baseline resolved peak, and 15 batches of finished products showed the similarity of above 0.95. The method was accurate and feasible and could be used as a simple and effective method to evaluate the quality of the traditional Chinese medicines.

ObjectiveTo recover the effect of rehabilitation therapy on the automatic nervous system(ANS)of patients with stroke. MethodsThe multiple index measurement was applied to measure ANS after stroke in 31 patients. The therapy of the Bobath,Brunnstrom and Rood were used as the basic methods for 3 months.ResultsThe balance index of the automatic nerve after treatment by the rehabilitation therapy was higher markedly than before(P<0.01).There is a correlativity with recovery of the movement function. Conclusions The rehabilitation can improve the function of automatic nerve.

Objective To evaluate the efficacy and safety of infliximab plus methotrexate combination therpy in Chinese with rheumatoid arthritis patients.Methods This was a double-blind placebo-controlled phaseⅢclinical trial,173 patients who had active rheumatoid arthritis were randomised to placebo(n=86)or infliximab(n=87)group on a background of a stable dosage of methotrexate.Patients were assessed at weeks 0,2,6,14 and 18.Results At week 2,the American College of Rheumatology(20)response criteria,which represent a 20% improvement from baseline,the same results with swollen joint count,tender joint count,du- ration of morning stiffness,VAS score,CRP,ESR were achieved in 52.9% of patients,compared with 14.0% of patients receiving placebo plus methotrexate.A 20% improvement was achieved in 75.9% of infliximab plus methotrexate at week 18,compared with 48.8% of patients on placebo plus methotrexate(P=0.0003).A 50% improvement was achieved in 43.7% of infliximab plus methotrexate at week 18,compared with 25.6% of pa- tients on placebo plus methotrexate(P=0.011).Infliximab was well-tolerated;withdrawals for adverse events as well as the occurrence of serious adverse events or serious infections were similar to those in the placebo group.There was only one case of tuberculosis in the treatment group.Conclusion Treatment with infliximab plus methotrexate is more effective than methotrexate alone in patients with active rheumatoid arthritis.It has rapid onset of effect and the efficacy is persistent.

Objective To investigate the effect of recombinant adenovirus mediatied human endostatin (rAD-GFP-ES)on rats with collagen typeⅡinduced arthritis(CIA),and explore the mechanism of inflamma- tion and cytokines inhibition on rats CIA.Methods The rAD-GFP-ES was amplified and purified.The model of rat CIA was induced by intradermal injection of typeⅡcollagen combined with complete Freund's adjuvant(CFA). On the second day after the injection,the therapeutic administration of rAD-GFP-ES(1?10~(11)pfu?kg~(-1)?week~(-1)?4 weeks)were performed to the rats.The mean arthritis index(AI)was scored every week since then.The relative concentrations of ES,IL-I?,TNF-?in sera collected at the fourth week were evaluated by western blotting. Results①The titer of the purified rAD-GFP-ES and rAD-GFP was 6.6?10~(12)pfu/ml and 4.8?10~(12)pfu/ml,re- spectively(A_(260nm)/A_(280nm)＞1.3).②The concentration of ES in sera of the group treated with rAD-GFP-ES was 2.4-lold higher compared to the normal group.③The mean arthritis index of the group treated with rAD-GFP- ES was much lower than that of the model group.The administration of rAD-GFP-ES could significantly de- creas the production of IL-1?and TNF-?in sera.Conclusions①The rAD-GFP-ES is efficiently expressed in vivo.②The rAD-GFP-ES has an inhibitory effect on the arthritis index of rat CIA.③IL-1?and TNF-?are involved in the pathogenesis of RA.The rAD-GFP-ES has an inhibitory effect on the expression of IL-1?and TNF-?in rat CIA.

In this review, we advance a new concept in developing vaccines and/or drugs to target specific proteins expressed during the early stage of Bacillus anthracis (an thrax) infection and address existing challenges to this concept. Three proteins (immune inhibitor A, GPR-like spore protease, and alanine racemase) initially identified by proteomics in our laboratory were found to have differential expres sions during anthrax spore germination and early outgrowth. Other studies of different bacillus strains indicate that these three proteins are involved in either germination or cytotoxicity of spores, suggesting that they may serve as potential targets for the design of anti-anthrax vaccines and drugs.

Immunohistochemical and electron microscopic techniques and image analysis were employed to investigate the regulation of cardiac AT1A and AT2 subtype receptors in rats during cardiac remodeling following myocardial infarction (MI). Positive immunostaining for AT1A and AT2 receptors was observed in myocytes and vessels with AT1A being more than AT2. Three days after MI, disappearance of myocardial cross striation and fibroblast hyperplasia were found with electron microscopy. AT1A receptor protein expression in myocardial noninfarcted portion notably increased compared with that in sham-operated control rats (P<0.001). No apparent changes were observed in AT2 receptor (P>0.05). Two weeks after MI, myocyte cross striation and collagen deposition were found. Meanwhile, AT1A receptor staining decreased compared with that of three days after MI (P<0.01), but there was still more than that of the control (P<0.05). AT2 receptor was significantly increased compared with that of the sham-operated control rats (P<0.001). These results suggust that both AT1A and AT2 receptor protein expression was upregulated in noninfarcted myocardium after MI, and the regulation of AT1A and AT2 receptors after MI may be involved in post-infarction cardiac remodeling.

Objective To explore the expression of hypoxia-inducible factor-1?(HIF-1?) protein and its mRNA in cultured cortical neurons after hypoxia,ischemia or hypoxia-ischemia(HI) and explore the possibilities of HIF-1? gene therapy in HI neurons.Methods The in vitro models of HI,pure hypoxia and pure ischemia were established using embryonic day 16-18 rats cortical neurons.Immunohistochemical and in-situ hybridization were performed to examine the expression of HIF-1? protein and its mRNA at different reperfusion time points in neurons.Results The expression of HIF-1? protein was very week in normoxic cultured neurons,but was up-regulated while treated with hypoxia and(or) ischemia.HIF-1? expression reached peak at 4 to 8 h after reperfusion with HI,which were statistically significant higher than that at other time points(Pa=0),and decreased gradually at 12 h.Furthermore,HIF-1? protein expression was significantly higher in HI group compared with that in the pure hypoxia or ischemia group(Pa=0).HIF-1? mRNA reached peak immediately after HI,decreased gradually at 2 h,and returned to the baseline at 8 h after reperfusion.Conclusions HIF-1? expression on cortical neurons is regulated differently with hypoxia,ischemia or HI treatment,HIF-1? gene therapy for HI neurons maybe a useful method in the future studies.
