OBJECTIVETo observe the clinical efficacy of combination of traditional Chinese medicine and western medicine in the treatment of patient bitten by agkistrodon halys pallas, and the changes in peripheral blood inflammatory factors (hs-PCR, IL-6, TNF-alpha).

METHODNinty-eight patients were divided into three groups according to their hospitalization dates: the western medicine group, in which 32 patients were treated with antivenom serum (6 000 U) for five days, once every day; the traditional Chinese medicine group, in which 32 patients were treated with anti pit viper No. 2 concentrated decoction (300 mL), twice to three times every day, for five days; and the combined traditional Chinese medicine and western medicine group, in which 35 patients were treated with the combination of Chinese and Western medicine treatment described above. Then blood samples of all of patients were obtained, and serum factors (hs-PCR, IL-6, TNF-alpha) in peripheral blood were measured by Elisa assay. Another 30 health volunteers were chosen as the normal control group.

RESULTThe serum inflammatory factors were significantly higher in all patients of the three groups than that in healthy control before treatment (P < 0.01), and decreased significantly after treatment. In particular, the more remarkable reduction was found in the combined traditional Chinese medicine and western medicine group compared with the western medicine group and the traditional medicine group (P < 0.01). Symptom elimination in the three groups was superior to the western medicine group and the traditional medicine group at the first day and the third day of treatment (P < 0.05, P < 0.01). Total clinical effective rate was 100% in the combined traditional Chinese medicine and western medicine group, 84. 37% in the traditional medicine group and 65.62% in the western medicine group, the clinical effective rate of the combined traditional Chinese medicine and western medicine group was notably superior to that of the western medicine group and the traditional medicine group (P < 0.01).

CONCLUSIONThe serum inflammatory factors increased significantly in patients bitten by agkistrodon halys pallas. Treatment with the combined traditional Chinese medicine and western medicine can significantly decrease the serum inflammatory factors, and increase clinical effect, with more obvious clinical efficacy compared with the western medicine group and the traditional medicine group.

Objective To investigate the relationship and clinical significance of blood plasma brain natriuretic peptide (BNP) and Keshan Disease (KD). Methods Seventy KD patients and 30 healthy volunteers in endemic area were investigated with Doppler Echocardiography for the measurement of left ventricular end-diastolic diameter(LVEDD) and left ventricular ejection fraction (LVEF), and the plasma BNP levels were determined with microparticle enzyme immunoassay. Results The BNP levels in plasma in KD patients [(444.61±102.31), (87.21±23.15)ng/L] were significantly higher than that of healthy volunteers [(34.91±15.21)ng/L],the differencesbeing statistical significant (q=39.74,5.82,P<0.01). The BNP levels in chronic KD patients were higher than that of latent KD patients (q=37.62,P<0.01). The plasma BNP levels in KD patients with LVEDD 60 nun [(928.80±134.27)ng/L] were significantly higher than those of patients with LVEDD 55～60 mm [(89.24±52.31)ng/L] and LVEDD<55 nun [(67.14±6.92)ng/L],the differencesbeing statistical significant (q=44.30,48.16, P<0.01), The plasma BNP levels in KD patients with LVEF<35%[(1654.21±421.35) ng/L] were significantly higher than those of patients with 35% ~ 50%[(421.54±112.32)ng/L] and50% [ (81.21±72.85 ng/L)], the differencesbeing statistical significant(q=24.91,72.66, P<0.01), The BNP levels in LVEF 35%～50% were higher than that of 50% (q=11.84,P<0.01). Conclusion The plasma BNP levels were important for the diagnosis, grouping, therapeutic effect and prognostic evaluation of KD.

In order to confirm the role that the 49th amino acid residue plays in enzymatic inactivity of Glutamine 49 phospholipase A2(Gln49-PLA2),site-directed mutagenesis of its 49th amino acid gene codon was conducted using PCR.Aspartic acid 49 phospholipase A2(Asp49-PLA2-Q49D-PLA2),the mutant of Gln49-PLA2 was expressed in E.coli with pET32a+ vector.The fusion protein,expressed as inclusion body,after being denatured,was on-column refolded and purified by immobilized metal affinity chromatography(IMAC),and then cleaved by Factor Xa.The mature Q49D-PLA2 mutant was obtained by Hitrap SP cation exchange and Superdex 75 gel filtration chromatography,with the recovery rate of 1.3%,and the specific activity of the mature Q49D-PLA2 mutant was 72 U/mg.It has been demonstrated that the 49th glutamine amino acid residue is the main reason in enzymatic inactivity of Gln49-PLA2 and the results are helpful for denatured protein refolding,especially in rich disulfide bonds conditions.

OBJECTIVETo select optimal media and conditions for the tissue culture of Dendrobium lituiforum.

METHODThe basic media, light illumination condition, phytohormone, and natural aqueous extracts. were tested and compared. The chlorophyll contents and soluble protein contents were measured.

RESULTN6 medium was suitable for embryo germination and growth. 1/2 MS + NAA 0.5 mg x L(-1) cordd be used as the optimal protocorm multiplying media. Culture 20 days in darkness in advance, and then in light is useful to embryo germinate. 1/2 MS+ NAA 0-0.5 mg x L(-1) is beneficial to protocorm multiplication largely. N6 + 6-BA 2.0 mg x L(-1) + NAA 0.5 mg x L(-1) + 10% potato juice is useful to protocorm differentiation. Phytohormone and potato juice added to the media promoted chlorophyll content and souble protein content. N6 + NAA 0.5 mg x L(-1) + 10% banana juice is the best medium for plantlet rootage and strengthening.

CONCLUSIONConcentration of inorganic salt, nitrogen source and illumination condition are important to embryo germination and growth. The nitrogen source type has effect on the protocorm multiplication. The chlorophyll contents and souble protein contents may be index to indicate the growth condition of plantlets, which can help to select the optimal media.

OBJECTIVETo explore the central mechanism of moxibustion on analgesic effect.

METHODSMale Wistar rats were screened by pain threshold value before making model, and 48 rats whose pain threshold was (250 +/- 25) g were selected. Twelve male Wistar rats were randomly selected as a normal group. For the rest rats the rheumatoid arthritis (RA) model was duplicated by raising in a windy, cold and wet environment combined with injection of Freund's complete adjuvant (FCA), and then they were randomly divided into a model group, a moxibustion group and a moxa volatile oil group, 12 rats in each group. The moxibustion and the moxa volatile oil igroup were treated with moxibustion and moxa volatile oil at "Shenshu"(BL 23) and "Zusanli"(ST 36), respectively, for 15 days. No interventions were added on the model group and the normal group. The pain threshold in Iinjured foot and the expression of hypothalamic POMC mRNA and PDYN mRNA in rats were observed.

RESULTSCompared with the normal group, the pain threshold and the expression of hypothalamic POMC mRNA and PDYN mRNA in the model group were increased (all P < 0.01). Compared with the model group, the pain threshold and the expression of hypothalamic POMC mRNA and PDYN mRNA in the moxibustion group were increased significantly (all P < 0.01), but no statistically significance in the moxa volatile oil group (P > 0.05). Compared with the moxa volatile oil group, the above-mentioned observative indices in moxibustion group were all increased significantly (all P < 0.01).

CONCLUSIONMoxibustion has obvious analgesic effect and its mechanism may be related to the increasing expression of hypothalamic POMC and PDYN mRNA through the warming effect of moxibustion.

OBJECTIVETo induce the differentiation of K562/MDR1 cells into dendritic cells (DC) with multidrug resistance property.

METHODSK562/MDR1 cells and K562 cells were cultured in the presence of GM-CSF and IL-4 to generate DC and matured by TNF-α. On d14 K562/MDR1-DC and K562-DC cells were harvested and the expressions of CD1a, CD83, CD80, CD86, HLA-ABC and HLA-DR were assessed by flow cytometry (FCM). The antigen presentation function of K562/MDR1-DC and K562-DC was determined by allogenic mixed lymphocyte reaction (Allo-MLR). The expression of P-glycoprotein and the intracellular accumulation of daunorubicin (DNR) were detected by FCM. The sensitivity of K562/MDR1-DC and K562-DC cell to vincristine, adriamycin was measured using MTT assay.

RESULTSBoth K562/MDR1 and K562 cells were differentiated into dendritic cells in the presence of cytokine cocktails, showing the morphologic and immunophenotypic characteristics of DC. K562/MDR1-DC more markedly enhanced proliferation of allogeneic lymphocytes in MLR than K562-DC. High level expression of P-glycoprotein and efflux of DNR were demonstrated in K562/MDR1-DC. K562/MDR1-DC showed multidrug resistance property, with higher IC(50) to VCR and ADM than that of K562-DCs.

CONCLUSIONK562/MDR1 cells can be differentiated into DC with the presence of cytokines, the induced K562/MDR1-DC cells express high level of P-glycoprotein and acquire the multidrug resistance property.

OBJECTIVETo summarize clinical and molecular features of two children with autosomal recessive chronic granulomatous disease caused by CYBA mutations.

METHODThe clinical records and CYBA mutations were reviewed for analysis of infections and inflammatory complications.

RESULTThe first case was a girl diagnosed with "liver and spleen abscess" in our hospital when she was 2.9 years old, with past history of neonatal impetigo and recurrent purulent lymphadenitis and positive family history. The results of DHR123 flow-cytometry showed that positive phagocytes after phorbol ester (PMA) stimulation was 84.63%. CYBA mutation analysis showed that she had heterozygous 35C > T, Q3X and IVS-2A > G. The second case was a boy diagnosed with "sepsis (salmonella D)" when he was 4 years old with a past history of impetigo, sepsis, perianal abscess, skin infection and positive family history. The results of flow cytometry showed that positive phagocytes after PMA stimulation was 96.13%. CYBA mutation analysis showed that he had homozygous 35C > T, Q3X and his parents were all carriers. All of them had BCG related axillary lymphnode calcification.

CONCLUSIONA22CGD cases had recurrent purulent infections (skin, lymphnode, liver and spleen, lung, blood), DHR123 flow cytometric analysis helped the diagnosis of CGD, CYBA mutation analysis ascertained the diagnosis of A22CGD.

This work was directed at obtaining a better gene carrier to improve the effects of gene delivery. Neutral liposomes made from cholesterol, lecithin and DOPE by reverse evaporation technique were used for encapsulating DNA-HAP complex which was made from DNA and optimized HAP. The sizes of complexes and the efficiency of encapsulation were detected. The efficiency of transfection into Hela cells was shown by observation of X-gal staining and measurement of transfection efficience. The average size of complexes was 643nm, the average encapsulating efficiency of DNA in microspheres reached 11.67%. These Lipid-Hydroxyapatite-DNA complex (LHD) could be transfected into mammalian cells. The Lipid-Hydroxyapatite-DNA complex prepared by reverse evaporation technique could be applied availably in DNA delivery system, and it gave another thinking to increase the gene transfection of non- viral genetic vector.
