0.05 ).But the difference of positive ratio between 1-year-old group was significant in 6 cases of B19 DNA positive (P0.05).Conclusion There are no markedly association between kawasaki disease and human parvovirus B19 infection.

0.05).3.Thirty-three point three percent of animals from parental strain group were found fibrillations potentials and the po-sitive sharp waves in gastrocnemius electromyogram,no obvious abnormal waves were found in animals from both waaF mutant and control group.Conclusions The ganglioside-like epitope in LOS of CJ is critical antigen in inducing GM1-IgG antibody and in inducing conduction block of peripheral nerve,therefore,provide a support for the molecular mimicry theory as a pathogenesis in the axonal GBS following CJ infection.

To study the chemical constituents of the Entada phaseoloides (L.) Merr., seeds of Entada phaseoloides were extracted with 70% ethanol at room temperature. Isolation and purification were performed by silica gel, reversed-phase silica gel column chromatography and semi-preparative HPLC. Structures of the pure compounds were established on the basis of spectral analysis. Four sulfur-containing amide compounds were isolated from the n-BuOH-soluble fraction and identified as entadamide A-beta-D-glucopyranosyl-(1-->3)-beta-D-glucopyranoside (1), entadamide A (2), entadamide A-beta-D-glucopyranoside (3) and clinacoside C (4). Compound 1 is a new compound. Compound 4 is isolated from the genus Entada for the first time.

Objective To investigate the quantity of perforin (PF) expressed on peripheral lymphocytes of active systemic lupus erythematosus (SLE) patients and its distribution in lymphocytes subsets. The effect of glucocorticosteroid on PF expression is also explored. Methods Phenotype analysis of peripheral lymphocytes was carried out by flow cytometry. SLE patients with SLEDAI≥10 (n=16) and normal controls (n=12) were enrolled into this study. The PF expressed on the iymphocytes of SLE patients with disease flares (n=10) Was studied before and after glucocorticosteroid treatment. Results SLE patients with active disease were characterized by higher proportions of PF-positive lymphocytes and higher perforin density. PF and CD8 double positive T cell proportions was evidently increased. The proportions of PF-positive lymphocytes was correlated to SLEDAI (r=0.673). After a short period of glucocorticosteroid therapy, a reduced expression of PF was observed. Conclusion There is an increased expression of perforin in peripheral lymphocytes from SLE patients with active disease. CD8 positive T cell subsets expand significantly in those patients. In addition, the frequency of PF-positive lymphocytes is correlated with SLEDAI. Finally, glucocorticosteroid inhibits the expression of perforin.

ObjectiveTo explore the relationship between the changes of neuro-electrophysiology and prognosis in children with Guillain-Barr? syndrome(GBS).MethodsThirty-eight children with GBS were divided into group A(rapid recovery,n=16) and group B(slow recovery,n=22) according to the time required for podosoma motor function recovery,at the same time,they were divided into the better prognosis group(n=22) and the worse prognosis group(n=16),for analyzing the difference between group A and B in terms of age,preceding infections,maximal Hughes grades and neuro-electrophysiology including motor conduction velocity(MCV),distal complex muscle action potential(dCMAP) and F wave,and investigating the related factors with the prognosis of GBS.Results1.MCV of tibial nerve was(40.2?2.53) m/s and(33.4?2.46) m/s in group A and group B,respectively;MCV of peroneal nerve was(45.2?3.23) m/s and(38.3?2.16) m/s in group A and group B,respectively,and the difference between group A and group B was significant(Pa0.05);abnormal rate of F wave(68.42%) was higher than abnormal rate of MCV(42.11%) and dCMAP(42.11%)(Pa

To develop a method to estimate the anti-Aspergilli activity of active ingredients of Chinese herbs. With the broth microdilution testing procedure proposed by NCCLS, anti-Aspergilli activity of active ingredients ( cinnamalde-hyde, cinn. and citral) of Chinese herbs was determined.The MIC values of cinn. to Aspergillus flavus, A.fumigatus were 0.100?g /mL , 0.050?g/mL.The MIC values of citral to A. flaws, A.fumigatus were 2.600?g/mL, 0.650?g/ mL.These results demonstrate that citral and cinn. have high potency activity against Aspergillus spp. .The research may provide references to establishing a standard for evaluating the effect of anti-Aspergilli Chinese herbs.

In the present study, the specifically knockdown models of P-gp or MRP2 were constructed by using a series of chemically synthesized small interfering RNA (siRNA) in vitro. The expression of P-gp and MRP2 was measured by real-time PCR and Western blot, and the function was evaluated by applying P-gp and MRP2 substrate, rhodamine and methotrexate. The results showed that MRP2 siRNA-3 or P-gp siRNA-2 significantly decreased the mRNA expression of MRP2 or P-gp, the inhibition ratio was 68% or 84%; MRP2 siRNA-3 or P-gp siRNA-2 at a dose of 80 nmol x L(-1) significantly reduced the protein expression of MRP2 or P-gp at 48 h after treatment, the inhibition ratio was 62% or 70%. Meanwhile, other transporters were not influenced by siRNA. When pretreatment with MRP2 siRNA-3 or P-gp siRNA-2, the efflux of methotrexate or rhodamine decreased significantly and the intra-cellular concentration increased. The results suggested that chemically synthesized siRNA could significantly inhibit the expression and function of MRP2 and P-gp, and the model of RNAi in vitro could be used to evaluate the role of efflux transporters in transportation of drugs.
