Objective To investigate the applieation of restriction display (RD) technique in the preparation of HCV probes of clinical genotyping microarray. Methods Restriction enzyme Sau3A Ⅰwas chosen to digest the full-length HCV cDNAs of three distinct subtypes, i.e.1a, 1b and 2a. The resultant restrictive fragments were then ligated with universal adapters. PCR primers were designed to match the universal adapters but with one "nesting" base overhanging at the 3′- end. The PCR reactions were performed by ten pairs of different primer combinations. The differential genes were separated through polyacrylamide gel electrophoresis and silver staining. The second-round PCR was performed using the isolated bands as PCR templates. The purified PCR products were then cloned into T-vectors. The recombinant plasmids were extracted from positive recombinant clones and the target gene fragments were sequenced. Results The target HCV gene fragments ranging from 200 to 900bp were isolated and sequenced, which were correlated precisely with the RFLP (Restriction Fragment Length Polymorphism) prediction. A total of 66 different fragments were obtained, averaging about 22 for each subtypes. These fragments could be further used as probes in HCV microarray preparations. Conclusion RD technique is of great value in obtaining a large number of equal sized gene probes, which provide a swift protocol in generating DNA probes for the preparation of microarrays.

Objective To approach the selection of appropriate period and mode of blood purification for treatment of patients with severe acute pancreatitis(SAP)based on acute physiology and chronic health evaluationⅡ(APACHEⅡ)score. Methods The clinical data of 89 patients with SAP were retrospectively analyzed. They were assigned into two groups:the hemoperfusion(HP)and short continuous veno-venous hemodiafiltration(SCVVHDF) group(HP+SCVVHDF,49 cases)and the HP and hemodiafiltration(HDF)group(HP+HDF,40 cases). All the patients were evaluated by APACHEⅡscore. In the HP+HDF group,26 cases with APACHEⅡ<15 were in group A, while 14 cases with 15-25 in group B. In the HP+SCVVHDF group,31 cases with the score 15-25 were in group C, and 18 cases with<15 in group D. One week after the treatment,APACHEⅡscore,oxygenation index(PaO2/FiO2), C-reactive protein(CRP),serum creatinine(SCr),alanine transaminase(ALT)and mortality were observed in all the groups. Results Compared to those before treatment,the APACHEⅡ scores(group A:7.35±2.12 vs. 10.52±3.26,group B:14.35±4.76 vs. 18.43±4.08,group C:11.83±3.85 vs. 19.39±3.64,group D:6.92±2.54 vs. 11.61±2.19),the levels of CRP(mg/L,group A:85.28±23.48 vs. 195.23±56.77,group B:172.67±36.69 vs. 232.65±62.86,group C:112.43±29.48 vs. 257.29±68.39,group D:76.23±29.05 vs. 206.37±65.49),SCr (μmol/L,group A:107.56±73.01 vs. 225.81±119.06,group B:291.49±123.27 vs. 391.76±273.48,group C:254.89±104.37 vs. 403.62±261.53,group D:112.36±55.36 vs. 258.74±128.25)and ALT(U/L,group A:86.93±27.04 vs. 127.56±84.35, group B:116.34±43.98 vs. 189.15±102.85, group C:94.85±74.42 vs. 178.73±87.21,group D:88.49±29.32 vs. 138.24±90.58)after treatment were all decreased markedly in the four groups. The levels of PaO2/FiO2 were obviously higher in the 4 groups after treatment〔mmHg(1 mmHg=0.133 kPa), group A:293.42±31.26 vs. 253.60±26.62,group B:254.12±35.73 vs. 137.56±23.48,group C:283.21±37.48 vs. 131.96±0.45,group D:305.75±29.66 vs. 267.74±31.42〕,but no statistical significant differences in above indexes between group A and group D were found(all P>0.05),while the APACHEⅡ score,PaO2/FiO2,CRP, SCr and ALT were improved more significantly in group C than those in group B(P<0.05 or P<0.01). The mortality rate of those SAP patients with APACHEⅡscore<15 was lower than those in cases with APACHEⅡscore 15-20〔6.82%(3/44)vs. 24.44%(11/45),P<0.05〕. Conclusions Blood purification is an effective measure to save patients with SAP. The APACHEⅡ score used to select the mode of blood purification in appropriate period for treatment of SAP has guiding significance. Currently the modes of blood purification have limited value and cannot cure all SAP patients.

Objective To investigate the association of promoter hypermethylation of secreted frizzled-related proteins (SFRPs) in patients with colorectal cancer. Methods The promoter hypermethylation of SFRPs in 20 sporadic colorectal cancer tissues and adjacent mucosa were detected by methylation-specific PCR. The amplified DNA was subcloned into the T-A cloning vector and sequenced. Two colorectal cancer cell lines (HCT116 and SW480) were treated with 5-aza-2' deoxycytidine for demethylation. The promoter hypermethylation and protein expression of SFRPs in colorectal cancer cell lines were detected by methylation-specific PCR and Western blotting. Results It was demonstrated that the hypermethylation of SFRP 1, 2, 4 or 5 was 19/20,17/20,3/20 or 13/20in cancer tissues, respectively, whereas it was 12/20, 8/12, 1/20 or 7/20 in adjacent mucosa,respectively. SFRP 1, 2 or 5 methylation was more frequently found in cancer tissue than in adjacent mucosa (P~0.05). Methylation of SFRP 1, 2, 4 and 5 were found in HCT116 cell line, but only SFRP1 and SFRP2 were found in SW480 cell line. There was a negative correlation between protein expression and methylation of SFRPs. The Western blotting revealed that SFRP protein re-expressedafter it treated with 5-aza-2' deoxyeytidine. Conclusion Methylation of SFRP 1, 2 or 5 gene is associated with the evolution of eolorectal cancer, and is closely related to silencing expression.

ObjectiveTo investigate the optimal reconstruction windows for coronary angiography using 320-detector row dynamic volume CT (DVCT) and evaluate their effects on image quality,radiation dose and diagnostic accuracy.MethodsFrom 77 patients [mean heart rate (70 + 13) bpm,range:46-102 bmp] were scanned with retrospective ECG-gating 320-detector row DVCT.The relationship between heart rate and optimal reconstruction windows was analyzed.From 53 patients [mean heart rate ( 75 ±11 ) bpm,range:57-114 bpm] were scanned with prospective ECG-gating 320-detector row DVCT.The effects of prospective ECG-gating on image quality,radiation dose and diagnostic accuracy were evaluated.Friedman test was performed for image quality scores in random groups.Linear regression and Spearman correlation were performed to test bivariate data.ResultsThe proportion of systolic duration in the cardiac cycle increased significantly with higher heart rate (r =0.78,P <0.01 ).The image quality in systolic and diastolic phases were significantly influenced by heart rate ( r =0.38,0.82 ; P < 0.01 ).According to the regression analysis of image quality score in different heart rate groups,the optimal reconstruction windows were determined as followed:when heart rate was < 70 bpm,the optimal reconstruction windows should be preset at 65%-80% ; 70 to 80 bpm,70%-85% ; 81 to 90 bpm,70%-90% ; >90 bpm,35%-50%.Compared with retrospective ECG-gating,prospective ECG-gating which preset reconstruction windows according to the phases mentioned above,could decrease radiation dose [(6.1 ± 3.8 )vs (12.4 ± 7.0) mSv],without deteriorating the image quality (t =6.5,P < 0.01 ).However,in higher heart rate,the radiation dose of prospective ECG-gating DVCT was still higher ( r =0.64,P < 0.01 ).ConclusionsDVCT can provide high image quality in a wide range of heart rate with prospective ECG gating.It is still recommended to control heart rate strictly since the radiation dose increases significantly in high heart rate.
