Objective To investigate the expression and significance of platelet membrane glyco- proteins and antiplatelet antibody in patients with anaphylactoid purpura.Methods Forty-five patients with anaphylactoid purpura were divided into three groups according to their clinical manifestations,15 in dermal purpura group,18 in mixed group and 12 in nephritis group.The expression of CD62P,CD63 and CD41 in these 45 patients was detected by flow cytometry.The level of antiplatetlet antibody was analysed by ELISA with monoclonal antibody as the probe.Results The percentage of CD62P,CD63 and the level of an- tiplatelet antibody in patients in acute phase were significantly higher than those in regressive phase and those in normal control.Neither of the expression of CD62P,CD63 and CD41,nor the level of antiplatetlet antibody in nephritis group was significantly different from that in the mixed group.Compared with dermal purpura group,the percentage of CD62P was significantly higher in the nephritis group and mixed group. There was no significant difference in CD41 expression among all groups.Conclusion Abnormal humoral immunity exists in anaphylactoid purpura.The activation of platelet could be closely related to the progress of anaphylactoid purpura.CD62P and CD63 could be considered as an index for monitoring of symptoms, determination of prognosis and predicting the outcome in anaphylactoid purpura.

Objective To construct the recombinant adeno-associated virus vector(rAAV) expressing the human tissue kallikrein(HK)gene and to detect the expression of interested gene in human umbilical vein endothelial cells(HUVEC)which were infected with different titers of rAAV. Methods The HK gene was cloned into the pAAV-MCS and co-transfected AAV-293 cells with other two plasmids(the pAAV-RC,and pHelper)by lipofectamine.The recombinant AAV(rAAV HK)particles was harvested and its viral titer was measured.HUVEC were infected with different titers of rAAV-HK particles.Seventy-two hours later,the expression of the interested gene was detected by RT-PCR and ELISA.Results The AAV expression system of human tissue kallikrein gene was successfully constructed.The viral titer of recombinant AAV reached 6.2?10~7 particles/ml. When compared with the control group,the transcription of HK gene in the group which was infected with rAAV-HK increased significantly[(0.59?0.12)vs(0.26?0.05)(P＜0.05)],and the expression of HK in the HUVEC was three times more than that in the control[(120.1?40.9)vs (30.8?12.8)](P＜0.001).The transcription of eNOSmRNA in the infected HUVEC was higher than that of the control[(1.19?0.28)vs(0.66?0.11)](P＜0.05).The transcription of caspase-3 mRNA was lower than that of the control[(0.30?0.25)vs(0.67?0.27)](P＜0.05).And there was no obvious variation happened in the transcription of VEGF,ET-1,TR-B,bradykinin B1 receptor and Bradykinin B2 receptor.Conclusions When co-transfected AAV-293 cells with three plasmids (pAAV-HK,pAAV-RC,pHelper),the HK gene expression is significantly and stably increased. Introducing HK gene into HUVEC can improve endothelial transfection efficiency.

Objective To evaluate and analyze relationship of plasma level of N-terminal probrain natriuretic peptides (NT-proBNP) and serum level of cystatin C (CysC) with cardiac and renal functions in patients with chronic heart failure (CHF) , and explore significance of CysC measurement in early diagnosis for renal damage in patients with CHF. Methods Totally, 162 patients with CHF and 150 normal healthy (controls) undergone routine physical check-up at, Taizhou People's Hospital, Jiangsu were enrolled in the study. Their plasma level of NT-proBNP and serum level of CysC, as well as serum levels of creatinine ( SCr) , urea nitrogen ( BUN) were measured and echocardiography was performed. Glomerular filtration rate (eGFR) was evaluated by modification of diet in renal disease (MDRD) study group formula. Results Compared with the control group, blood levels of NT-proBNP, CysC, SCr, BUN and left ventricular end diastolic diameter ( LVEDD) all elevated, both eGFR and left ventricular ejection fraction ( LVEF) decreased (P <0. 05 or P <0. 01 ) in CHF group, and CHF patients were prone to complicate with renal dysfunction (P<0. 01). Blood levels of NT-proBNP and CysC elevated significantly and LVEF lowered significantly in CHF patients with NYHA functional classes II , III and IV than those in control group. There was significant difference in blood levels of NT-proBNP and CysC between patients with varied NYHA functional classes (P<0. 05). Blood levels of NT-proBNP and CysC reversely correlated with LVEF (r = -0. 36, P < 0. 01 and r = - 0. 39, P < 0. 01) . Blood level of CysC correlated with that of NT-proBNP ( r = 0. 87 , P < 0. 01). Results of logistic regression analysis showed that elevated blood levels of NT-proBNP and CysC were risk factors for mortality during hospitalization in patients with CHF. Conclusions Patients with CHF were more likely to complicate with renal dysfunction than controls, with main manifestations of more severe damaged eGFR, more severe heart failure and more obviously renal damage. Blood levels of NT-proBNP and CysC can be used as indicators for evaluating exacerbation of chronic condition, and serumlevel of CysC can be used as marker for early diagnosing renal damage in patients with CHF.

The rice gall dwarf disease, caused by the Rice gall dwarf virus (RGDV) is a serious disease occurring in rice in many regions of Guangdong province. As a basis to control the disease we have studied the genomic diversity of a variety of isolates from different locations. Genome segment 8(S8), encoding a main outer capsid protein (Pns8) of RGDV five isolates (BL, CH, DQ, GZ, XY) from Guangdong province was cloned and sequenced. The results revealed that all the S8 segments of the five isolates consisted of 1 578 nucleotides and had a single open reading frame (ORF) extending for 1 301 nucleotides from nucleotide 21 which encoded a polypeptide of 426 amino acids with an estimated molecular weight of 47.4 kDa. The S8 full-length sequence and the ORF sequence shared 97.3%-98.8% and 97.3%-99.1% nucleotide sequence identities within the five Chinese isolates, and shared 94.8%-95.6% and 95.0%-96.0% identities with those of the Thailand isolate respectively. The deduced amino acid sequence of Pns8 in GZ isolate was identical to that in the Thailand isolate, while the amino acid sequence variability of Pns8 within five Chinese isolates ranged from 0.5% to 2.1%. These results indicate that the S8 segment of RGDV is highly conserved in different isolates from different locations. The S8 cDNA from the XY isolate was cloned into the plasmid vector pET-28b(+) and a fused expression protein with an apparent molecular mass of 51kDa was specifically detected in an analysis of Escherichia coli Rossetta(DE3)Ⅱcells. To our knowledge, this is the first report on analysis of the RGDV segment 8 sequence and genetic comparison of different RGDV isolates and their protein expression.

OBJECTIVETo detect the expression of PTEN, PIP3 and cyclin D1 in oral squamous cell carcinoma and precancerous lesions and analyze their correlation.

METHODSImmunohistochemistry SP method was used to detect the expression of PTEN, PIP3 and cyclin D1 in 63 cases of oral squamous cell carcinoma, 29 cases of simple hyperplasia, 33 cases of dysplasia, and 25 cases of normal oral mucosa.

RESULTSThe negative or low expression of PTEN in oral squamous cell carcinoma was 25%, which was remarkably lower than that in other groups. The positive expression of PIP3 in simple hyperplasia, dysplasia and oral squamous cell carcinoma was 66%, 64%, and 76% respectively, which were much higher than those in normal oral mucosa. The positive expression of cyclin D1 in oral squamous cell carcinoma was 49%, which was significantly higher than that in other groups. The negative correlation between PTEN with PIP3, cyclin D1 and the positive correlation between PIP3 and cyclin D1 were observed.

CONCLUSIONSPTEN may play a role in the oncogenesis of oral squamous cell carcinoma, and PTEN may down-regulate the expression of PIP3, and then down-regulate the expression of cyclin D1, which leads to the suppression of cell growth.

The aging process of human colonic epithelium involves a slow decline in physiological vigor and an increasing susceptibility to age-related diseases, especially, colon cancer, but the molecular mechanisms of the aging and susceptibility of aged colonic epithelium to carcinogenesis is still unclear. Identification of aging related proteins in colonic epithelium will help to reveal the molecular mechanisms of colonic epithelial aging and age-related colonic diseases. Therefore, the total proteins of human normal colonic epithelial tissues from 10 young and 10 old men were separated by two-dimensional gel electrophoresis(2-DE), respectively. PDQuest software was applied to analyze 2-DE images, the differentially expressed protein spots of colonic epithelium between young and old groups were identified by matrix-assisted laser desorption/ionization time of flight mass spectrometry(MALDI-TOF-MS), and the expression levels of partial identified proteins were determined by real-time quantitative PCR and immunohistochemistry. Well-resolved, reproducible 2-DE maps of human colonic epithelial tissues from young and old men were established, 17 aging related proteins were identified by MALDI-TOF-MS, and the differential expression levels of partial identified proteins were confirmed by real-time quantitative PCR and immunohistochemistry. The results indicate that injury of mitochondrial function and decline of antioxidant capability are important reasons for the aging of human colonic epithelium, and four differential proteins (guanine nucleotide-binding protein beta subunit-like protein, stress-70 protein, 40 S ribosomal protein SA and chloride intracellular channel protein1) may be involved in susceptibility of aged colonic epithelium to carcinogenesis.
