Objective To obtain the prevalence data on human T Lymphotropic virus (HTLV) infection in 2 339 blood donors of an endemic coastal region of Fujian, China. Methods Serum antibodies to HTLV in the donors were detected by a home made double antigen sandwitch ELISA kit. All the ELISA positive samples were further confirmed by Western blot (WB) and/or polymerase chain reaction (PCR) combined with sequencing. Results Nine samples were confirmed as HTLV 1 infection among the 2 339 donors. A man whose wife is one of the nine was also detected to infect by WB and PCR. Conclusion The prevalence of HTLV infection was 0.38% in the endemic coastal region of Fujian, China.

In order to prove the feasibility of preparation of the drug-incorporated stent by immersing stent wires in the monoclonal antibody (mAb) solution, fluorescence stain and image analysis were used to evaluate the L-PLA-coated stent. Absorption was measured using a radioisotope technique after preparing the mAb-incorporated stent, and the absorption curve was determined from the absorption data. In an in vitro perfusion circuit, the antibody was eluted from the stent matrices, and the related influence factors were evaluated based on the release data.

OBJECTIVETo investigate the clinical significance of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in the treatment of spinal tuberculosis.
METHODSSixty-seven patients (41 males and 26 females, ranging in age from 23 to 61 years) with active spinal tuberculosis in our hospital (from Mar. 2004 to Mar. 2007) were included in this study. The tuberculosis focus were located either in cervical spine, thoracic spine or in lumbar spine. After 4 to 6 weeks anti-tuberculosis chemotherapy, all the patients underwent one-stage operation (focus debridment) and auto-bone graft combined with internal fixation. Blood test for ESR and CRP were carried out at different times before and after operation.
RESULTSThe average ESR was (79.4 +/- 35.6) mm/h, and the average CRP was (44.3 +/- 17.5) mg/L before chemotherapy, indicating active tuberculosis focus. After 4 to 6 weeks chemotherapy, the average ESR was (45.3 +/- 21.0) mm/h,and the average CRP was (26.7 +/- 11.8) mg/L, the differences were statistically (P < 0.05), and the clinical symptoms of spinal tuberculosis relieved in all patients. Four weeks after operation, the average ESR dropped to (42.8 +/- 16.5)mm/h, the average CRP dropped to (23.8 +/- 10.0) mg/L statistically (P < 0.05). Eight weeks after operation, the average value of ESR and CRP were at normal level in 47 cases, indicating inactive tuberculosis focus. Focus healing was achieved in 65 patients after short-term chemotherapy.
CONCLUSIONThe level of ESR and CRP are high in active spinal tuberculosis and low when focus controlled. ESR and CRP are reliable parameters in evaluation the treatment and prognosis of spinal tuberculosis.

OBJECTIVETo compare the efficacies of portal vein stenting and transcatheter arterial chemoembolization (TACE) combined therapy performed with or without endovascular implantation of iodine-125 (125I) seeds strand in patients with hepatocellular carcinoma (HCC) and main portal vein tumor thrombus (MPVTT).
METHODSOne-hundred-and-six patients with HCC complicated by MPVTT who were treated with portal vein stents and TACE, either with (Group A, n=56) or without (Group B, n=50) endovascular implantation of 125I seeds strand, between July 2005 and April 2011, were retrospectively analyzed. Overall survival, stent patency, and procedure-related adverse events were compared between the two groups.
RESULTSThe technical success rate was 100% for placement of 125I seeds strands and stents in the obstructed main portal vein. No serious procedure-related adverse events were recorded. Group A had significantly higher median survival (335 days vs. group B: 146 days; P=0.001, hazard ratio (HR)=2.244). Additionally, group A had significantly higher median stent patency (400 days vs. group B: 190 days; P=0.005, HR=2.479).
CONCLUSIONThe combination therapeutic strategy of portal vein stenting and TACE with endovascular implantation of 125I seeds strands improves the survival of HCC patients with MPVTT complication.

OBJECTIVETo establish a new and rapid GeXP based multiplex PCR assay for the detection and typing of human papillomavirus 6, 11, 31, 33 and 52.
METHODSNucleotide sequences of HPV6, HPV11, HPV31, HPV33 and HPV52 from NCBI were obtained and compared. Genotype-specific primers were then designed and the sensitivity and specificity of multiple PCR assay was evaluated. Optimized assay was further validated with 30 clinical specimens collected from the cervical secretions of patients.
RESULTSA GeXP based multiplex PCR was developed for sensitive detection and reliable differentiation of five HPV genotypes (HPV6, 11, 31, 33 and 52),
CONCLUSIONA GeXP based multiplex PCR assay is demonstrated to be a new and rapid technique for simultaneous detection and typing of 5 different human papillomaviruses.

A simple, rapid and sensitive colorimetric loop mediated isothermal amplification (LAMP) method was established to detect HPV6 and HPV 16 respectively. The method employed a set of four specially designed primers that recognized six distinct sequences of HPV6-E6 or HPV16-E7 for amplification of nucleic acid under isothermal conditions at 63 degrees C for one hour. The amplification process of LAMP was monitored by the addition of HNB (hydroxy naphthol blue) dye prior to amplification. A positive reaction was indicated by a color change from violet to sky blue and confirmed by real-time turbidimeter and agarose electrophoresis. Thirteen cervical swab samples having single infection with 13 different HPV genotypes were examined to evaluate the specificity. A serial dilution of a cloned plasmid containing HPV-E6 or HPV-E7 gene was examined to evaluate the sensitivity. The results showed that no cross-reaction with other HPV genotypes was observed. The colorimetric LAMP assay could achieve a sensitivity of 1000 copies, 10-20 times lower than that of real-time PCR. The assay was further evaluated with 62 clinical specimens and consistent results were obtained compared with the detection using Kai Pu HPV Genotyping Kit. We concluded that this colorimetric LAMP assay had potential usefulness for the rapid screening of the HPV6 or HPV16 infection in the laboratories and hospitals of provincial and municipal region in China.
