Objective To establish a method for rapid diagnosis and identification of seven species human herpesviruses infection.Methods Primers and oligonucleotide probes were designed and synthesized based on the highly conserved regions of the DNA polymerase genes in human herpesviruses, namely herpes simplex virus type 1 (HSV-1),HSV-2,varicella-zoster virus (VZV),Epstein-Barr virus (EBV),cytomegalovirus (CMV),and human herpes virus 6 (HHV-6A/6B).DNA microarrays were made by printing the oligonucleotide probes on the special glass slides.A total of 282 blood specimens from children with suspected infection were analyzed by this DNA microarray technique,and the results were compared with those of TaqMan PCR.Results The products of the seven human herpesviruses after PCR amplification could be used to identify the virus species with DNA microarrays.The detection limits were 10 copies/?l for HSV-1,HSV-2,VZV,EBV,CMV,HHV-6A,and HHV-6B,respectively.The assay did not show cross-reaction to the DNA extract of hepatitis B virus,staphylococcus aureus,E.coli,Candia albicans and human genome.Among the 282 samples,59 were positive for human herpesviruses DNA.Compared with those of TaqMan PCR,the sensitivity and specificity of the microarray assay were 96.7% and 99.5%,respectively,and the index of accurate diagnosis was 0.962.Conclusions This DNA microarray for identifying human herpesviruses species is specific and sensitive,and may serve as an efficient technique for simultaneous detection and species identification of human herpesviruses in clinical specimen.

Objective To summarize our experience in the management of extensive small bowel necrosis from acute superior mesenteric arterial (SMA) embolism. MethodsSeven cases with extensive small bowel necrosis from acute SMA embolism were treated from 1991 to 1999. Results In this group small bowel of 28～ 30 cm and 70～90 cm were remained respectively in 3 and 4 cases after surgery. Two patients died of septic shock while the other 5 developed short or ultra short bowel syndrome and were finally cured by means of combined intravenous nutrition and oral feeding. 5 patients were followed up for 18～36 months, all are in good health. Conclusions Timely diagnosis and prompt operation are important to elevated survival rate. SMA embolectomy helps in preserving living intestine. For patients with short or ultra short bowel syndrome, comprehensive measures of intravenous nutrition and stepwise oral feeding in combination can quickly restore digestive and absorptive function of the residual intestine.

Objective To examine outcomes of superficial vein stripping for vein varicosis caused by combination of superficial and deep venous reflux and the effect on deep vein reflux. Methods From January 2004 to December 2006, twenty patients (22 lower extremities) with combined superficial and deep venous reflux were enrolled for evaluation, patients with superficial venous reflux alone worked as controls.All patients underwent superficial vein stripping and followed up for 2 years. Venous clinic severity score (VCSS) and color duplex ultrasound test were used to evaluate the change of clinic symptoms and valve reflux of deep veins. Results Preoperative VCSS of superficial and deep vein reflux group and superficial vein reflux group was 7.1 ± 2. 9 and 6. 6 ± 2. 0 respectively (P = 0. 44). At two years after operation the VCSS was 2. 3 ± 1.2 and 1.8 ± 0. 8 respectively without significant statistic differences, whereas comparing postoperative VCSS with individual preoperative parameters there was a significant decrease (P <0. 01). In combined superficial and deep vein group, deep venous reflux reduced in 7 limbs, progressed in 4 limbs, no change in 12 limbs. While in superficial reflux alone group, deep venous reflux occurred in 4 limbs.Conclusions Superficial vein stripping effectively improves symptoms of great saphenous vein varicosis of lower extremity caused by combination of superficial and deep vein reflux without a significant effect on the stares of deep vein reflux.

Objective To investigate the image quality,radiation dose and iodine intake of CT pulmonary angiography (CTPA) in patients using low tube voltage (100 kVp) combination of different noise indexes (NI) and low concentration contrast agent.Methods A total of 80 patients with suspected pulmonary embolism (PE) and other pulmonary diseases who had undergone CTPA were divided into four groups (A,B,C and D),with 20 patients in each group.Group A underwent 120 kVp CT scan protocol in combination with NI=25 and 370 mg iodine/ml contrast agent,while groups B,C and D underwent 100 kVp CT scan protocol in combination with NI=30,35,40,and 320 mg iodine/ml contrast agent,respectively.All images were restructured using 60％ adaptive statistical iterative algorithm 2.0.Objective image quality evaluation included CT values of pulmonary artery,noise values of pulmonary artery,signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR).Subjective image evaluation used a 5-point scoring method and was conducted by two independent radiologists.The CT dose index of volume (CTDIvol),dose-length product (DLP) and iodine intake was recorded,and the mean value was calculated.The DLP was converted to the effective dose (ED).Analysis of Variance or Kruskal-Wallis test was used to evaluate the differences among the four groups in terms of image quality,radiation dose and iodine intake.Results There was a significant difference in CT values of pulmonary artery among the groups A,B,C and D (P＜0.05),and the CT values of pulmonary artery of group A was the lowest.There was no significant differences in noises of pulmonary artery,SNR,CNR and subjective indexes scores among the groups A,B,C and D (P＞0.05).There was a significant difference in iodine intake among the groups A,B,C and D,iodine intake of the group A was the highest,iodine intake of the group D was the lowest.The iodine intake of groups B,C and D decreased by 12.4％ (42/340),13.2％ (45/340) and 15.0％ (51/340) relative to group A,respectively.There was a significant difference in radiation dose among the groups A,B,C and D,The CTDIvol,DLP and ED of group D decreased by 45.3％ (3.9/8.6),48.6％ (120/247) and 48.3％ (2.02/4.18) relative to group A,respectively (P＜0.01).Conclusion Low tube voltage combination with high NI value and low concentration contrast agent can more effectively reduce the radiation dose and iodine intake for CTPA while maintaining diagnostic image quality.
