Dermatophagoid.es farinae allergen Ⅰ (Der f Ⅰ ) has been extracted and purified from spent culture medium of Dermatophagoid.es farinae by affinity chromatography coupled with anti-Der f Ⅰ McAb for the first time in China. Furthermore,its physicochemical properties were analysed. By SDS-PAGE,.Der f Ⅰ was estimated to have a molecular weight of 24 kDa and appeared as only one protein band. By isoelectric focusing ,it was revealed to have pIs of 4. 8 - 7. 5 with six protein bands,suggesting that Der f Ⅰ is heterogeneous with complicated composition.

Aim The effect and mechanism of human placental extract(HPE) on the lipoprotein-cholesterol metabolism, peroxidation and the function of platelet aggregation in hyperlipaemia rats were abserved.Methods Wistar rat with hyperlipaemia models were given each HPE 0.4 ml (100 g)-1?d-1 through lavage for 12 days.The serum levels of TG,TC,LDL-C,HDL-C and HDL2-C in its subgroup were measured.The activies of LPO and SOD in both blood and liver tissue were determined .The effect of HPE on lipidosis of liver were abserved by fat dyeing.The levels of 6-keto-PGF1?,TXB2 in plasma and maximum platelet aggregation rate were measured by ELASA. Result The levels of HDL-C and HDL2-C were increased (P

Objective To investigate the effect of serum-deprivation on the changes of [ Ca2+ ] i and the protein release of S100A13 and fibroblast growth factor 1 ( FGF-1 ) in thyroid cancer TT cell,and to reveal the role of Ca2+in the protein release of S100Al3 and FGF-1.Methods The protein expressions of FGF-1 and S100A13 in TT cells under serum-deprivation were detected by Western blot.The released FGF-1 protein from TT cells in the supernatant fluid was detected by ELISA.Realtime dynamic examinations on the change of 1 h [ Ca2+ ] i in TT cells under serum-deprivation were detected by confocal laser scanning microscopy.Then,the effect of EGTA( 2.5 mmol/ L),BAPTA-AM (2.5 μmol/L)on distributions of the fluorescence of S100AI 3 and FGF-1 in TT cells under serumdeprivation for6 h were detected by indirect immunofluorescence.Results The expressions of FGF-1 and S100A13 in TT cells after serum-deprivation for4 h and 6 h were reduced( P＜0.05 or P＜0.01 ),but the released FGF-1 protein from TT cells in the supernatant fluid was elevated ( P＜0.05 or P＜0.01).Confocal laser scanning of Ca2+ imaging indicated that [ Ca2+ ] i of serum-deprivation TT cells maintained the relative stabilization within 23 win,but the rapid rise of [ Ca2+ ] i achieved peak value 1.6 μmol/L after 30 min,and remained stable for about 17 win,and thereafter 40 win slowly dropped to a low level From 40 win to 60 win the [ Ca2+ ] i was about 0.3-0.6 μ mol/L.The average [ Ca2+ ] i was higher than that in normal group,EGTA group,and BAPTA-AM group within 1 h.The protein expressions of S100A13 and FGF-1 did not drop obviously in EGTA group and BAPTA-AM group.Conlusion The release of S100A13 and FGF-1 from TT cell under serum-deprivation is possibly related with the change of [ Ca2+ ]i.Both Ca2+-chelating agents EGTA and BA PTA-AM are able to inhibit the rise of [ Ca2+ ] i and release of S100A 13 and FGF-1 from TT cells under serum-deprivation.

Objective To study the incidence of PTEN, p53 and Ki-67 expression in astrocytoma and show the relationship between PTEN, p53 expression and the proliferation activity. Methods The surgical specimens from 68 brain astrocytoma patients were analysed to detect PTEN, p53 and Ki-67 expression with immunohistochemical method. Results The incidence of PTEN, p53 and Ki-67 expression was 54.4 %,45.6 % and 48.5 % respectively in astrocytoma. With the grade of astrocytoma increasing the levels of PTEN protein decreased, on the other hand the levels of p53, Ki-67 increased. There was a negative correlation between PTEN expression and grade of astrocytoma while there was a positive correlation between p53, Ki-67 expression and grade of astrocytoma by using the Spearman Correlation test to analyse the data. The incidence of Ki-67 positive expression was 24.3 % in 37 cases exhibiting PTEN positive staining, whereas the incidence of Ki-67 positive expression was 77.4 % in 31 cases exhibiting PTEN negative staining. In statistics, there was an inverse correlation between PTEN and Ki-67 expression. Conclusion There is an inverse correlation between histopathological grades of astrocytoma and PTEN expression. A positive correlation is found between p53, Ki-67 expression and histopathological grades of astrocytoma. PTEN can inhibit tumor cell proliferation in astrocytoma.

OBJECTIVETo evaluate the impacts on the short-term efficacy and the long-term prevention of recurrence of allergic rhinitis treated with the triple-strong stimulation at Dazhui (GV 14) so as to provide the convenient and long-term effective therapy of acupuncture and moxibustion for allergic rhinitis.

METHODSOne hundred and twenty cases of allergic rhinitis were randomized into an acupuncture group, an acupuncture + medication group and a triple-strong stimulation group, 40 cases in each one. In the acupuncture group, acupuncture was applied at Dazhui (GV 14), Fengchi (GB 20), Baihui (GV 20), Yintang (GV 29) and the others, stimulating with reinforcing manipulation for the deficiency and reducing manipulation for the excess, once every day. In the acupuncture + medication group, on the basis of acupuncture therapy, claritin (loratadine tablets) was supplemented for oral administration, 10 mg, once every two days, continuously for 30 days. In the triple-strong stimulation group, on the basis of acupuncture therapy, the strong needling, strong cupping and strong moxibustion were applied at Dazhui (GV 14). This combined therapy was given once every day in the first 3 days and once every two days afterwards. The 10 day treatment made one session, at the interval of 3 days between the sessions and totally 3 sessions were required in the three groups. Separately, before treatment, after treatment and in 6 months after treatment, the changes of symptom and physical sign score and value of single item symptom including nasal itching, nasal blockage, sneezing and rhinorrhea were observed in the patients of the three groups. And the long-term clinical efficacy was compared among the three groups.

RESULTSThe symptom and physical sign score and the value of single item symptom were all reduced in the three groups after treatment and in 6 months after treatment (P < 0.001, P < 0.01, P < 0.05). The results in the triple-strong stimulation group were superior to the other two groups (all P < 0.05). In the triple-strong stimulation group, the total effective rate was 92.5% (36/40) in the follow-up of 6 months after treatment, which was better than 60.5% (23/38) in the acupuncture group and 69.2% (27/39) in the acupuncture + medication group (both P < 0.01).

CONCLUSIONThe combined therapy of acupuncture and the triple-strong stimulation at Dazhui (GV 14) achieves the reliable and effective result in the clinical treatment of allergic rhinitis and displays the good role on the prevention from long-term recurrence.
