To study the role of anti- C. albicans IgY and serum in protection of C. albicans infection of several animal models. To develop three animal models of C. albicans infection: a burned rat model of C. albicans infection, a mouse model of vaginal candiasis and a immunosuppression mouse model of C. albicans infection. And we compared the contribution of anti- C. albicans IgY and serum to the clearance of the C. albicans in three animal models of C. albicans infection. Anti- C. albicans IgY can protect against C. albicans infection in a burned rat model of C. albicans infection and a mouse model of vaginal candidiasis. The serum can effectively protect the mice from disseminated candidiasis in a immunosuppression mouse model. Humoral immunity component involving anti- C. albicans IgY and serum protect against C. albicans infection in a burned rat model of C. albicans infection ,a mouse model of vaginal candidiasis and a immunosuppression mouse model of C. albicans infection.

To investigate the effect of flavonoids from Sophora flavescens in aging mice induced by D-galactose and its mechanism. Totally 60 mice were randomly divided into six groups: the control group, the model group, the piracetam group (positive control group) and flavonoids from S. flavescens low, medium and high doses groups. Except for the control group, all of the rest groups were subcutaneously injected with D-galactose (160 mg x kg(-1)) for successively 30 days to establish the sub-acute senescent model. Meanwhile, flavonoids from S. flavescens low, medium and high doses groups were respectively administered with 150, 300 and 600 mg xkg-('1)of flavonoids from S. flavescens for 30 days. The learning and memory abilities of mice were determined by avoiding darkness ex-eriment and jumping stair experiment. The contents of malondialdehyde (MDA) tumor necrosis factor-aα NF-aα the activities of superoxide dismutase (SOD) monoamine oxidase-B (MAO-B) Na'(+)K'(+)-ATPase and Ca2(+ )-ATPase in the brain of mice were deter-ined respectively after the behavioral experiments. The activity of lactic dehydrogenase ( DH) in blood serum was also determined and analyzed by microscope after HE staining to observe the changes in hippocampal organizational structure. Compared with the model group, flavonoids from S. favescens medium and high doses groups showed significantly increases in the latency of avoiding darkness and jumping stair experiments; flavonoids from S. fllvescens low, medium and high doses groups and the piracetam group showed de-reases in the numbers of errors in avoiding darkness experiment; the flavonoids from S. flavescens high dose group and the piracetam group showed reduction- n the number of errors in jumping stair experiment (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens me-ium and high doses groups and the piracetam group showed improvements in the activities of SOD, Na'(+)K'(+)ATPase in the brain of mice and declines in the contents of MDA and TNF-aα the activity of MAO-B in the brain of mice, the activity of LDH in blood serum (P <0 . 5 or P <0 . 1). Flavonoids from S. flavescens low, medium and high doses groups and the piracetam group also showed im-rovement in the activity of Ca2(+ )ATPase, with statistical difference from the model group (P <0 . 5 or P <0 . 1). The pathological result showed decreases in the number of cells of hippocampal dentate gyrus area, sparse cell arrangement, incomplete cellular mor-hology, scarce cytoplasm, blurred boundary between nucleus and cytoplasm, nuclei anachromasis, irregular pyknosis and unconspicu-us nucleoli in the model group. Compared with the model group, flavonoids from S. flavescens low, medium and high doses groups and the piracetam group showed improvements in hippocampal organization tissues. Flavonoids from S. favescens can improve the learning and memory ability of senescent mice induced by D-galactose. Its mechanism may be correlated with the enhancement of anti-oxidative actions by lowering TNF-aαcontent, which results in the stability of cell membrane and the reduction in MAO-B activity.

Objective: To explore the curative effect and partial mechanism of modified Guipitang combined with Xingnao Kaiqiao acupuncture in the treatment of non-dementia vascular cognitive impairment (VCIND). Method: Totally 122 patients with VCIND admitted to the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine (TCM) from May 2017 to October 2018 were randomly divided into modified decoction group (39 cases), acupuncture group (42 cases) and combination group (41 cases). All of the three groups were orally given routine anticoagulants and lipid-lowering drugs. The decoction group was orally given modified Guipitang 150 mL/times, 2 times/day, in addition to the routine treatment, the acupuncture group was treated with Xingnao Kaiqiao acupuncture method in addition to the routine treatment, involving Shuigou, Neiguan (bilateral), Sanyinjiao (bilateral), Sishencong, Xuanzhong (bilateral) and Taixi (bilateral) acupoints, 2 times/day, for six days a week, the combined group was treated with Xingnao Kaiqiao acupuncture in addition to modified Guipitang. All of the three groups were treated for 8 weeks. The Montreal cognitive assessment scale (MoCA scale, Beijing version) and activity of daily life (ADL) scale, TCM symptoms and clinical efficacy were scored before treatment, 4 weeks after treatment and 8 weeks after treatment in three groups. Serum levels of calcitonin gene-related peptide (CGRP) and cone-like protein-1 (VILIP-1) were measured by enzyme-linked immunosorbent assay at different time points. Result: Compared with decoction group and acupuncture group, MoCA score, ADL score and TCM syndrome score of the combined group were decreased, the total effective rate was increased significantly after 4 and 8 weeks of treatment, the serum CGRP content was increased, and the VILIP-1 content was decreased. Conclusion: Modified Guipitang combined with Xingnao Kaiqiao acupuncture has a definite curative effect on VCIND with heart and spleen insufficiency syndrome. Its mechanism may be related to the expansion of blood vessels, the alleviation of blood supply of brain and the reduction of neuron injury.
