    Objective: To study the correlation influence of quercitrin hydrate on PI3K-Akt signaling pathway and nerve-nutrient effect in vitro in rats. Methods: The newborn rat cerebral cortex neurons were cultured in vitro. The experiment was divided into normal control group, LY294002 (10 μmol/L) group, quercetin (100 μmol/L) group and LY294002 (10 μmol/L)+quercetin (100 μmol/L) group. MTT assay was used to investigate the effect of LY294002 on the neuronal viability. Taking advantage of the availability of the LY294002 (a specific inhibitor of PI3K upstream of Akt), to explore whether it would block the neurotrophic effects of quercitrin hydrate on neurite outgrowth and survival. Results: MTT assay showed that quercitrin hydrate at the concentration of 5 μmol/L, 10 μmol/L and 20 μmol/L had no effect on the survival rate of cortical neurons and had no cytotoxic effect. Compared with the quercetin (100 μmol/L) group, the LY294002 (10 μmol/L)+quercetin (100 μmol/L) group reduced the number of survival neurons with neurites and the average length of neurites. Conclusion: LY294002 could block the neurotrophic effect of quercitrin, indicating that the neurotrophic effect of quercitrin played a role by activating the downstream PI3K-Akt signal transduction pathway.

    Objective: To study the relationship between up-regulation expression of Candida albicans (C.albicans) drug-resistant protein-1 (CDR-1) and C.albicans resistance to fluconazole (FLU). Methods: After 46 strains of C.albicans were isolated and identified from clinical samples by regular fungal isolation method, and the minimum inhibitory concentration (MIC) of C.albicans to FLU was determined by microdilution method. Based on the MIC level of C.albicans to FLU, 46 strains of C.albicans were divided into 3 groups, including FLU-resistant strain (R group),dose dependent FLU-sensitive strain (DS group), and FLU-sensitive strain (S group). The expression level of CDR-1 protein in each C.albicans strain was detected by Western blot, and the person correlation was used to analyze the relationship between the expression level of CDR-1 protein and MIC of C.albicans to FLU. Results: The median MIC values of C.albicans to FLU in R group, DS group and S group were 128 μg/mL,16 μg/mL and 1.5 μg/mL, respectively. The median MIC value of C.albicans to FLU in R group was higher than those in DS group and S group (all P<0.05). The relative level of CDR-1 protein expression of C.albicans in R group, DS group and S group were 6.15±1.97, 1.69±0.27 and 1.12±0.09, respectively. The relative level of CDR-1 protein expression of C.albicans in R group was higher than that of DS group and the S group (both P<0.05), and The relative level of CDR-1 protein expression of C.albicans in DS group was higher than that in S group (P<0.05). There was a positive relationship between the relative level of CDR-1 protein expression and the Logarithmic transformation of MIC value of C.albicans to FLU (r=0.773, P<0.05). Conclusion: The up-regulation expression of CDR-1 protein in C.albicans is an important factor for C.albicans resistance to fluconazole, and CDR-1 protein is a potential target to prevent the spread of C.albicans resistance to fluconazole.
