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 study the effects of strychnos alkaloids on the proliferation of adult rat neuroprogenitor cells.

METHODSStrychnos alkaloids free of strychnine and brucine were extracted from Strychnos nux vomica, and the effects of Strychnos alkaloids on the survival of HEK293 and PC12 cells were evaluated using MTT assay. In vitro cultured adult rat neuroprogenitor cells isolated from the hippocampus were treated with different concentrations of Strychnos alkaloids for 2 days, and the cell proliferation was assessed using BrdU incorporation assay.

RESULTSAt the concentration above 0.5 mg/ml, Strychnos alkaloids produced toxic effect against HEK293 cells (P<0.0001), while for PC12 cells, Strychnos alkaloids inhibited the cell survival at the concentration as low as 5 microg/ml (P<0.0001). After 2 days of exposure to 50 microg/ml Strychnos alkaloids, the neuroprogenitor cells showed significantly decreased number of BrdU-positive cells (P<0.01), but the total cell number remained stable when compared with that of the control cells (P>0.05), whereas at the concentration of 100 microg/ml, Strychnos alkaloids produced obvious cytotoxicity against the neuroprogenitor cells.

CONCLUSIONStrychnos alkaloids can significantly inhibit the proliferation of adult rat neuroprogenitor cells, and this effect is probably selective, suggesting the potential of Strychnos alkaloids as a new drug for treatment of neurocytoma.

OBJECTIVETo study the association of human epidermal growth factor receptor family molecules expression in gastric cancer tissues with the prognosis of patients with gastric cancer.

METHODSClinical data of 161 patients with gastric cancer undergoing gastrectomy in Jiangsu Cancer Hospital between January 2006 and January 2007 were analyzed retrospectively. The expression of HER1, HER2, HER3 and HER4 was detected by immunohistochemistry. Association of the expression of HER family with the prognosis of patients was examined. Kaplan-Meier method was used to analyze the survival.

RESULTSHigh expression rates of HER1, HER2, HER3 and HER4 were 46.0% (74/161), 10.6% (17/161),55.9% (90/161) and 68.3% (110/161) respectively. Univariate analysis revealed that high expression of HER3 was associated with tumor invasion depth, lymph node metastasis, stage, neurovascular invasion, and overall 4-year survival. High expression of HER4 was associated with tumor distant metastasis and stage. High co-expression of HER2 and HER3 was associated with overall 4-year survival (P=0.023). Multivariate analysis revealed that high expression of HER3 and stage were prognostic independent factors.

CONCLUSIONUp-regulated expression of HER3 is associated with the poor prognosis in gastric cancer patients.

OBJECTIVETo investigate and compare the expression pattern and level of targeted anti-caries plasmids encoding different-size antigens in eukaryotic cells.

METHODSThe A-P fragment of PAc (surface protein antigen) was removed from pGJA-P encoding the signal peptide, extracellular domains of human CTLA-4, human Ig hinge, CH2 and CH3 domains, A-P fragment of PAc and GLU (glucan binding domain) region of GTF-I of Streptococcus mutans, to obtain the plasmid pGJGLU. pCI vector skeleton of pGJA-P or pGJGLU was replaced by pVAX1 to construct plasmids pGJA-P/VAX and pGJGLU/VAX. CTLA4-Ig-GLU fragment was removed from pGJGLU and inserted into the vector pEGFP-N1 to obtain the recombinant plasmid pGJGLU/GFP. The CHO cells were transfected with those plasmids by using liposome and the expression of fusion protein was observed with fluorescence microscope. ELISA was used to detect the expression level of fusion proteins in cultured supernatants.

RESULTSSpecific vesicles with green fluorescence could be observed in the CHO cells transfected with pGJGLU/GFP. The recombinant fusion protein could be detected in the cultured supernatants of CHO cells transfected with pGJA-P/VAX, pGJGLU/VAX and pGJGLU/GFP, of which the concentration was different. The highest concentration of recombinant fusion protein was observed in the supernatants of CHO cells transfected with pGJGLU/VAX.

CONCLUSIONSCTLA-4 targeted fusion protein could be expressed and secreted by eukaryotic cells. The size of antigen may affect the expression level of CTLA-4 targeted anti-caries DNA vaccine.

The study aimed to explore the changes of the immunocyte quantities and cytotoxicity in bone marrow, and how many hematopoietic progenitor cells retained after the bone marrow cells were activated by different combinations of various cytokines. Bone marrow cells were divided into four groups and were cultured in vitro: (1) Control: no cytokines were added. (2) IL-2 group: bone marrow cells were activated by IL-2. (3) CD3-AK group: bone marrow cells were activated by IL-2 and CD3-McAb. (4) CIK group: IFN-gamma, IL-1, IL-2 and CD3-McAb were added. CFU-GM assay and CD3 phenotype detection were performed before and after activating culture in all groups. The changes of cell quantities during culture and cytotoxicity of cultured cells were tested. CD3 positive cells markedly increased in both CD3-AK and CIK groups. The cell numbers and cytotoxicity of CD3-AK and CIK groups were higher than those of control or IL-2 group obviously after culture (P < 0.05). CFU-GM were decreased in all groups after culture and there had no significant difference among four groups. The combination of IL-2 and CD3-McAb not only stimulates the proliferation of marrow immunocytes and increases their cytotoxicity but retains enough hematopoietic progenitor cells as well. This combination of cytokines can be used to purge autologous bone marrow in vitro.
