The present study aimed to investigate the effect and the mechanisms of Bu-zhong-yi-qi-tang (BZYQ) on Spleen-Qi deficiency rat's model using nuclear magnetic resonance (NMR) metabolomics and multivariate statistical analysis methods. The rat Spleen-Qi deficiency model was established as follows: oral administration of Radix Rhei extract, loaded swimming and starvation for 24 h. The body weight and motor behavior of the rats were measured and recorded once a week. BZYQ could significantly improve body weight and behavioral of Spleen-Qi deficiency model rats compared with the model group (P < 0.05, 0.01). After drug administration, the changes in the levels of endogenous metabolites in the spleen including decreasing lactate, taurine and hypoxanthine, increasing glutamate and scyllo-inositol compared with the model group. The metabolomics approach is an effective tool for the investigation of the pharmacologic mechanism of BZYQ and it is helpful to further research.

Objective To explore the effect of nitric oxide (NO) on ?-aminobutyric acid B receptor (GABA_BR) subunits during recurrent febrile seizures (FS).Methods Twenty-four Sprague-Dawley rats aged 21 days were randomly divided into 4 groups: control group (37.0 ℃ water,n=8), FS group (45.2 ℃ water,n=8), FS + SNP group (45.2 ℃ water,n=8), FS+L-NMMA group (45.2 ℃ water,n=8). FS rats were induced 10 times in a warm-water bath, once every 2 days. The plasma level of NO was detected by the spectrophotometer. The expressions of GABA_BR subunit mRNA and c-fos gene were examined by in situ hybridization. The expressions of GABA_BR subunit and Fos protein were observed by immunohistochemistry. Results The plasma level of NO increased in FS + SNP group while decreased in FS+L-NMMA group compared with that in FS group. The expressions of GABA_BR_2 were down-regulated in FS+SNP group, while GABA_BR_1 hardly changed compared with those in FS group. In FS+L-NMMA group, both the expression of GABA_BR_2 and GABA_BR_1 up regulated compared with those in FS group. The expressions of c-fos gene and Fos protein were significantly enhanced after recurrent FS. SNP elevated the expressions of c-fos gene and Fos protein, while L-NMMA down regulated the expressions of them.Conclusion NO may play a regulatory role through modulating GABA_BR function in the pathogenesis of recurrent FS.

OBJECTIVETo investigate the expression and correlation of mast cell, Clusterin/apoJ and transforming growth factor-beta (TGF-beta) in the different stages of human dermal hemangioma.

METHODSImmunohistochemical stain technique (SABC) and toluidine blue (TB) stain technique were respectively used to detect the expression level of Clusterin/apoJ and TGF-beta and the number of mast cells in the different stages of human dermal hemangioma.

RESULTSThere was remarkable statistical difference between the advanced stage of proliferative hemangioma and the other stages of proliferative hemangioma in the number of mast cell(P<0.01). There was also remarkable statistical difference between the early stage of involutional hemangioma and the other stages of involutional hemangioma in the number of mast cell (P<0.01). The expression of Clusterin/apoJ and TGF-beta in the advanced stage of proliferative hemangioma was significantly higher than the other stages in proliferative hemangioma (P<0.01). The expression of Clusterin/apoJ and TGF-beta in the early stage of involutional hemangioma was significantly higher than the other stages in involutional hemangioma (P<0.01). There was a significantly positive correlation between Clusterin/apoJ and TGF-beta in the different stages of human dermal hemangioma (P<0.01). The expression level of Clusterin/apoJ and TGF-beta was positively correlated with the number of mast cell in the different stages of human dermal hemangioma (P<0.01).

CONCLUSIONMast cell may play a promotive role of apoptosis during the spontaneous regulate the expression of Clusterin/apoJ and promote the spontaneous involution of human dermal hemangioma.

ObjectiveTo explore the cognitive psychological characteristics of the insomniac and the effect of cognitive therapy.Methods93 insomniac in-patients were divided randomly into the trial group (n=47) and control group (n=46). The trial group was treated by cognitive therapy plus medicine. The control group was only treated with medicines. The treatment lasted for 8 weeks. Before and after treatment, patients of all two groups were examined by Beliefs and Attitudes about Sleep Scale (DBAS). 45 healthy individuals were also examined at the same time. The therapeutic effect was evaluated with Pittsburgh Sleep Quality Index (PSQI).ResultsBefore treatment, DBAS scores of insomniacs were significantly different from the healthy (P<0.001). After treatment, scores of DBAS and PSQI of the trial group were significantly different from that of the control group ( P<0.001).ConclusionThe cognitive treatment can change erroneous cognitions related to sleeping in the insomniac and improve the therapeutic effect.

OBJECTIVETo investigate human enterovirus 71 (EV71) resistance to type I interferon induced antiviral effect.

METHODSAfter type I interferons (alpha, beta) were incubated with HeLa cells, recombinant type I herpes simple virus (HSV-1) with green fluorescent protein (GFP) was inoculated onto the HeLa cells. HSV-1 proliferation was observed by GFP expression and PCR. After EV71 was inoculated onto HeLa cells incubated with the same quantity of interferon, proliferation of EV71 were detected by RT-PCR of 2A gene.

RESULTSRecombinant HSV-1 GFP expression and viral DNA replication obviously decreased in HeLa cells incubated with type I interferon (alpha, beta). However, EV71 effectively proliferated in the interferon irritated HeLa cell by RT-PCR.

CONCLUSIONHeLa cell irritated by type I interferon (alpha, beta) produced antiviral substance that inhibits HSV-1 proliferation. EV71 resisted the antiviral substance induced by type I interferon and could significantly replicate in the HeLa cells.

To investigate changes of 14-3-3beta from apoptosis induced by PrP106-126 polypeptide, HeLa cell was incubated with PrP106-126 for 4h or 8h. Nucleus changes and the expression of PARP were detected differently by Hoechst staining and Western blotting. Expressing of protein and mRNA from 14-3-3beta was determined by Western blotting and Real-time PCR. The results show that typical nucleus pyknosis and chip of apoptosis and degradation of PARP were induced by PrP106-126 peptide in HeLa cells. Degradation of 14-3-3beta appeared in apoptosis groups induced by PrP106-126 peptide. However, 14-3-3beta mRNA did not display any changes in apoptosis groups. This study indicated that degradation of antiapoptosis protein 143-3beta induced by PrP106-126 peptide may be one of pathogenesis mechanism of prion disease.
