【Objective】To observe the effect of acupoint external application of herbal drugs on pathological changes of nasal mucosa of allergic rhinitis mice. 【Methods】 Sixty BALB/c mice were divided into 5 groups: A(normal),B(model),C(treated with external application of herbal drugs on acupoints),D(treated with dexamethasone) and E(treated with PBS).Except group A,the mice in other groups were sensitized by ovalbumin(OVA).On the 15~(th) of the first sensitization,group C received external application of medicinal disc(mainly composed of Semen Sinapis, Rhizoma Corydalis,Herba Asari,Radix Kansui,Fructus Xanthii,etc.) on Dazhui (GV14)point,group D received intraperitoneal injection of 0.1?g/L dexamethasone(0.5?mL for each mouse) one hour before nasal dripping of OVA solution,and group E received external application of paper disc on Dazhui point and intraperitoneal injection of(0.1?g/L) PBS(0.5 mL for each mouse) one hour before nasal dripping of OVA solution,qd,for 4 weeks.After treatment,the mice were executed and the nasal mucosa was fixed in 4% paraformaldehyde.Routine paraffin slices were prepared and stained by haematoxylin and eosin.The pathological features of nasal mucosa were observed under light microscope,and eosinophil(EOS),neutrophil and lymphocyte count was performed in different groups.【Results】Compared to group A,the infiltration of EOS and neutrophil in nasal mucosa was obvious in group B(P0.05).【Conclusion】The infiltration of EOS in nasal mucosa plays an important role in the pathogenesis of allergic rhinitis and the decrease of EOS infiltration may be one of the therapeutic mechanism of external application of herbal drugs on acupoints for allergic rhinitis.

Objective:To observe neurotransmitter changes of post cerebral infarction depression (PCID) before and after being treated with amitriptyline or acupuncture of Baihui,in order to explore a good way with a less toxicity and good effect of treatment on PCID.Methods:The 60 patients were divided into treatment group and control group.Besides the basic treatment,the treatment group was given acupuncture of Baihui (DV20) and point injection therapy,the control group was given amitriptyline. Both before and after treatment,compared the two groups with HAMD score,neurologic impairment score,plasma 5-HT and NE,and observed the adverse events and side effects.Results:The results of two groups in monoamine neurotransmitter 5-HT(5-HT),norepinephrine (NE) and the HAMD scale were significantly improved.Conclusion:Acupunture of Baihui and point injection of Herba Erigerontis had equal effect to the amitriptyline on PCID.Furthermore,it had fewer venenosus side effects.It provided a new way for the use of the traditional Chinese medicine in treating PICD.

Objective: To observe effective of antitumor immunity elicited by heat shock protein70(HSP70) associated peptide complexes isolated from hepatoma (HCaF), a tumor model of no MHC Ⅰmolecule expression in mice. Methods: Specific active immunization and adoptive cellular immunization assay was adopted to observe the immunoprotective effect elicited by HSP70 associated peptide complexes purfied from the HCaF. Results: Mice immunized with HSP70 associated peptide complexes were protected from HCaF challenge. The immunoprotective effect in female mice was better than the male groups. Adoptively transferred immune spleen cells of mice which had been immunized with HSP70 associated peptide complexes could be elicited immunity against HCaF challenge, and the mice free of tumor can resist repeated challenge, the maximal challenge quantities exceeded 1?10 7 HCaF cells. Mice immunized once with spleen cells pulsed by HSP70 associated peptide complexes could also be elicited certain immunity against HCaF challenge. Conclusions: HSP70 associated peptide complexes derived from the HCaF can elicit no MHC Ⅰ molecule restrictive immunoprotective effect against HCaF and could be continuously enhanced by repeated challenge with alive HCaF cells. Adoptively transferred immune spleen cells of mice which had been immunized with HSP70 associated peptide complexes could provide protection against HCaF cells challenge.

Purpose　To investigate relationship between androgen receptor and apoptotic index and to further understand the tumor biology of prostate cancer. Methods　Fifty-six patients with histologically proven prostate cancer and 20 cases with benign prostatic hyperplasia(BPH) were collected. Androgen receptor(AR) were stained by 2H12 monoclonal antibody using immunohistochemical method. The apoptotic index (AI) was determined by the terminal deoxynucleotidyl transterase-mediated dUTP biotin nick end labeling (TUNEL) technique on serial sections of formalin fixed, paraffin embedded tissues. Results　AR was not found significantly difference (P>0.05) between prostate cancer and BPH. The association of AR with AI according to Gleason score were not observed in prostate cancer. AI were significantly higher in prostate cancer compared to BPH (P<0.05).AI were also significantly higher in AR-positive prostate cancer than in AR-negative prostate cancer（P<0.05）. Conclusion　AR expression can induce prostate cancer cells to become apoptosis, and may be a useful predictor in functional classification and endocrine response of prostate cancer.
