Objective Platelet activating factor(PAF),which has been implicated in the pathophysiology of inflammation in asthma,is degraded and inactivated by PAF acetlhydrolase(PAF AH).To investigate the association of PAF AH activity with genotype in asthmatic children.Methods We studied 57 asthmatic children and 30 normal controls. The plasma PAF AH genotype was detected as representative case with 3 different genotypes (Val/Val,Val/Phe and Phe/Phe) by allele specific polymerase chain reaction(AS PCR).The PAF AH activity in plasam was examined by the changes of substrate assay.Results In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group,and plasma PAF AH activition was absent 15.4 %.In another three groups plasma PAF AH activation were absent 2 %-3 %.There was significant difference of plasma PAF AH activity among 3 groups of genotype(Val/Val,Val/Phe and Phe/Phe).In the similar genotype, there was no significant difference of plasma PAF AH activity between the groups of control and asthma.Conclusions There was imbalace of PAF/PAF AH in asthmatic children. In severe asthmatic individuals plasma PAF AH activities were lower than those of mild or moderate groups and control group. PAF AH(Val279Phe) gene mutation was related with plasma PAF AH activity.

OBJECTIVETo observe blood uric acid levels and Goldstein grading, as well as their correlation in Wilson's disease (WD) patients with different Chinese medical syndrome types.

METHODSTotally 906 WD patients in line with inclusive criteria were assigned to 6 groups, i.e., the heart spirit confused by phlegm group (HSCP, 26 cases), the phlegm-fire disturbing heart group (PFDH, 90 cases), the retention of damp-heat group (RDH, 113 cases), deficiency of qi and blood group (DQB, 168 cases), the deficiency of Gan-yin and Shen-yin group (DGYSY, 327 cases), the deficiency of Gan and Shen group (DGS, 182 cases) due to different Chinese medical syndrome types. Recruited were another 160 healthy subjects having similar ages and diet structures, who came for medical examinations, as the healthy control group. Venous blood was collected from the medial cubital vein of each-patient on an empty stomach in early mornings to detect blood uric acid levels. Results Blood uric acid levels were lower in each syndrome type group than in the healthy control group (146.08 +/- 67.24 micromol/L in the HSCP group; 157.08 +/- 69.77 micromol/L in the PFDH group; 162.58 +/- 97.72 micromol/L in the RDH group; 156.20 +/- 62.63 micromol/L in the DQB group; 161.83 +/- 111.23 micromol/L in the DGYSY group; 194.41 +/- 90.01 micromol/L in the DGS group; 242.39 +/- 87.55 micromol/L in the healthy control group, P < 0.01). Blood uric acid levels were higher in the DGYSY group than in the other 5 syndrome groups (P < 0.01). Correlation analyses between Goldstein grading and blood uric acid showed that, along with increased Goldstein grade (that was aggravating disease conditions), WD patients' blood uric acid levels decreased (P < 0.01).

CONCLUSIONSWD patient's blood uric acid levels decreased more. Blood uric acid levels and Goldstein grading were different in various Chinese medical syndrome types. Blood uric acid levels had certain value in assessing the severity of WD.

OBJECTIVETo detect the immunoreactivity of targeted fusion anti-caries DNA vaccine pGJA-P in vitro, and the ability to enhance the immune responses compared with the non-targeted fusion anti-caries DNA vaccine pGLUA-P.

METHODSThe CHO cells were transfected with pGJA-P and the expression of recombinant protein in cultured supernatants were detected using Western blotting. 5 to 6-month-old female Japanese rabbits were immunized with either pGJA-P or pGLUA-P via either intramuscular injection (i.m.) or intranasal route (i.n.). The sera and saliva were collected and the antibody responses were checked by ELISA. The effect of immune sera on the synthesis of water-insoluble glucan by glucosyltransferase of S. mutans was examined.

RESULTSThe expressed protein could response to specific anti-GTF antibody. The antibody responses in serum generated by pGJA-P via i.m. were significantly higher than those generated by pGLUA-P (P < 0.01). The antibody responses in saliva generated by pGJA-P via i.n. were significantly higher than those generated by pGLUA-P (P < 0.01). The higher mucosal antibody response induced by pGJA-P via i.m. compared with pGLUA-P (P < 0.01) was detected. The immune sera of rabbits immunized by pGJA-P via i.m. most significantly inhibited the synthesis of water-insoluble glucan by glucosyltransferase.

CONCLUSIONSThe recombinant protein expressed by pGJA-P had the immunoreactivity to anti-GTF antibody. pGJA-P could induce faster and higher specific mucosal SIgA antibody responses via i.n. or serum IgG antibody responses via i.m. compared with non-targeted DNA vaccine, pGLUA-P. High titres of specific mucosal antibodies were found in rabbits immunized with pGJA-P via i.m. The immune sera of rabbits immunized by pGJA-P via i.m. displayed the ability of inhibiting the synthesis of water-insoluble glucan by glucosyltransferase.

Chronic myelogenous leukemia (CML) is a clonal myeloproliferative disease of transformed hematopoietic progenitor cells. In order to investigate the role of sphingosine kinase-1 (SphK-1)/sphingosine 1-phosphate (S1P) signal pathway in the expression of CML cells, and to explore whether P210(bcr/abl) involved is activating SphK-1/S1P signal pathwey, the expressions of SphK-1 and S1P receptor mRNA in bcr/abl positive K562 cells and bcr/abl positive primary CML cells were detected by RT-PCR, the imatinib mesylate, the specific inhibitor of P210(bcr/abl) was employed to inhibit the P210(bcr/abl) tyrosine kinases of K562 cells and CML primary cells, and then the intracellular SphK-1 activity was assayed. The results indicated that after being cultured with 2.5 micromol/L imatinib mesylate for 0.5, 2, 6, 24 and 48 hours, the intensions of inhibiting SphK-1 activity were 0.007%, 38.9%, 34.6%, 28.1% and 76.1% resepectively. SphK-1 activity in CML cells also was reduced by 2.5 micromol/L imatinib mesylate (16.8% - 41.9% decrease). It is concluded that the CML cells express SphK-1 and different S1P receptor, and P210(bcr/abl) fusion protein in CML cells can activate SphK-1.

An alpha-amylase inhibitor (alpha-AI) was isolated from white kidney beans (Phaseolus vulgaris L) by ethanol fractional precipitation, ion exchange chromatography and gel filtration column chromatography. It was a homogeneity glycoprotein demonstrated by SDS-PAGE and gel filtration on CL-6B. The glycoprotein contained 88.2% protein and was rich in aspartic acid, glutamic acid, leucine, threonine and serine. The carbohydrate moiety was consisted of Man, Glc, Gal and Xyl in a mole ratio of 2.42: 1.50: 1.52: 1.00. The glycan and the core protein backbone was connected by O-linkage as determined by beta-elimination reaction. The continuous oral administration of the alpha-AI (150 mg x kg(-1) x d(-1)) for 7 days can lower fasting blood glucose and 300 mg x kg(-1) x d(-1) alpha-AI for 7 days can improve the sugar tolerance on alloxan-dependent diabetic model rats. The result showed the alpha-AI obtained from white kidney beans had good hypoglycemic effect on alloxan induced diabetic rats and may have high potential pharmaceutical value as a regulative digestive-starch degradation in patients suffering from diabetes.

Omega-3 polyunsaturated fatty acids (PUFAs) have been broadly investigated and shown to exert many preventive and therapeutic actions besides their important role in maintenances human health and normal development. In mammals, the level of omega-3 PUFAs is relatively too low compared with omega-6 PUFAs, which metabolically and functionally distinct from omega-3 PUFAs and often have important opposing physiological functions. Either the inefficiency of omega-3 PUFAs or the excess of omega-6 PUFAs will cause many healthy problems. So methods have been sought to increase the amount of omega-3 PUFAs and to improve the omega-6/omega-3 ratio in body. In this study, the sFat-1 gene, which putatively encodes a omega-3 fatty acid desaturase, was chemically synthesized according to the sequence from Caenorhabditis briggssae (with codon usage modified), and constructed into a mammal expression vector pcDNA3. 1-sFat1-EGFP. This vector was introduced into CHO cells by lipid-mediated transfection, and it's expression quickly and effectively elevated the cellular omega-3 PUFAs (from 18-carbon to 22-carbon) contents and dramatically improved the ratio of omega-6/omega-3 PUFAs. Cellular lipids extracts from stably selected cells were analyzed with GC-MS and the results showed that amount of total omega-6 PUFAs dropped from 48.97% (in GFP cells)to 35.29% (in sFat-1 cells), whereas the amount of total omega-3 PUFAs increased from 7.86% to 24.02%, respectively. The omega-6/omega-3 ratio also dropped from 6.23 to 1.47. These data demonstrates the Caenorhabditis briggssae omega-3 Fatty Acid Desaturase gene, sFat-1, was synthesized successfully and can produce omega-3 PUFAs by using the corresponding omega-6 PUFAs as substrates, which shows its potential for use in the production of omega-3 PUFAs in transgenic animals.

The study was to understand the impact on the proliferation and cytotoxicity of donor's T cells during mobilization with rhG-CSF. The peripheral blood mononuclear cells (PBMNC) were collected from 15 donors before mobilization and on fifth day of mobilization with rhG-CSF. After the PBMNC were activated with 500 ng/ml of CD3 monoclonal antibody and 500 microg/ml of rhIL-2 for 96 hours, the activated T cells were collected for testing proliferation, cytotoxicity, Fas expression, perforin and Fas ligand (FasL) mRNA expression, the IFN-gamma concentration in the culture medium of the activated T cells was determined by radioimmunoassay. The results showed that the proliferation activity of T lymphocytes and the cytotoxicity of T cells activated with CD3 monoclonal antibody and rhIL-2 were reduced markedly after mobilization with rhG-CSF (P < 0.05). The Fas molecule expression in the activated T cells was very high both before and after mobilization with rhG-CSF (P > 0.10). The activated T cells expressed perforin mRNA and didn't express FasL mRNA both before and after mobilization with rhG-CSF. The concentration of IFN-gamma in the culture medium of the activated T cells decreased significantly after mobilization with rhG-CSF (P < 0.01). It is concluded that activity of proliferation and cytotoxicity of donor's T cells is impaired after mobilization with rhG-CSF.
