Objective To establish a specific,sensitive and applied method for the detection and differentiation of dengue virus types Ⅰ-Ⅳ,Japanese encephalitis virus and yellow fever virus.Methods Based on the genomes sequence analysis,6 pairs of primers were designed.The special capture probes of dengue virus types Ⅰ-Ⅳ,Japanese encephalitis virus and yellow fever virus were amplified,cloned and sequenced.Then the microwell plates were precoated using these capture probes,and the forward primers were labeled using biotin.The samples were then amplified using the biotin labeled forward primers and reward primers.The microwell plate hybridization was processed for detecting and differentiating the virus.The precoated DNA concentration,precoated time,hybridization temperature and hybridization time were optimized carefully.Results The A value of positive samples were over 0.5,while the average A value of the negative samples was less than 0.1.The S/N value exceeded 10.0.Sensitivity experiment suggested the method of PCR-ELISA could detect the virus RNA in 107 times dilution,while RT-PCR could detect the virus RNA in only 106 times dilution.The stability experiment of PCR-ELISA using DVⅠ suggested that the within-batch coefficient of variation was 6.21%,the between-batch coefficient of variation was 9.92%;the within-batch coefficient of variation in negative control was 1.92%,and the between-batch coefficient of variation in negative control was 3.68%.No visible changes were found on the performance of the coated microwell plates when stored in 4℃for 6 monthes.Conclusion PCR-ELISA is a more sensitive and specific method than RT-PCR is in the early detection and type identification of dengue Ⅰ-Ⅳ types virus,Japanese encephalitis virus and yellow fever virus.

Objective To investigate changes in glucocorticoid receptor (GR) expression and activity in lung tissue of acute lung injury induced by lipopolysaccharide (LPS) within 24h in rat. Methods A total of 70 Wistar rats were divided randomly into LPS treatment group and LPS+ Dexamethasone (Dex) treatment group. The GR mRNA and GR protein expressions in the lung tissue of LPS challenged rats were assessed by RT-PCR and Western blot at different time points. Electrophoretic mobility shift assays (EMSA) were used to determine the GR activity in the lung tissue. Results The expression level of GR mRNA was depressed, but it returned to normal level at 24h after LPS challenge. The expression level of GR was also lowered, reaching the lowest level at 8h. GR activity was decreased, reaching the lowest level at 1h, and remaining lower than that of normal control at 24h. Dex treatment showed no obvious effect on GR activity during the late period of treatment. Conclusion The GR protein expression decreases in lung tissue of acute lung injury in rats, and it maybe associated with the decreased expression of mRNA and accelerated degradation of GR protein. The activity of GR is inhibited sharply, resulting in glucocorticoid resistance.

Objective To find a solution to the long-term storage of enormous amount of imaging data in hospital picture archiving communication system (PACS). Methods Medical imaging data collected by devices of Digital Imaging and Communications in Medicine-3 (DICOM3) and non-DICOM3 were transformed into the storage format, metadata instance, and expression pattern of digital images standardized by DICOM3. Based on the requirements of data utilization and storage system and the optimal principle of function and value, the reasonable flow of imaging data in PACS network were scientifically allocated by application of on-line, near-line, and off-line storage patterns and by reasonable allocation of the volume and clusters of storage devices. Results The PACS storage system established by our method, characterized by super capacity of error tolerance, permanent unrestricted storage, quick in retrieval, and quick, convenient and reliable in storage and reading, could meet the requirements of long-term storage and management of enormous amount of medical imaging data. Conclusion Grading storage is the effective method for long-term storage of enormous amount of medical imaging data in PACS.

ObjectiveTo investigate the incidence, clinical features and preventive measurement of secondary hepato-biliary neoplasm (HBN) in patients with hepatolithiasis. MethodA clinical retrospective study was made on 27 hepatobiliary malignancy patients found among 556 consecutively admitted cases of hepatolithiasis from Jan. 1996 to Sep. 2000.Results The average incidence of hepatobiliary malignancy in patients with hepatolithiasis is 4.8%. In this series, preoperative definite diagnosis was made in 4 cases (4/27, 14.8%). Atypical liver abscess, refractory biliary system infection, progressive obstructive jaundice, CT or BUS scan abnormal findings, and epigastric masses are all clues to concurrent malignancy in patients of hepatolithiasis. ConclusionThere is high incidence of hepatobiliary malignancy in hepatolithiasis patients. Prophylactic partial hepatectomy for segments with stone and chronic infection may be an important measure to prevent ensuing malignancy.

Objective To investigate the changes in the expression of acid-sensing ion channel 3(ASIC3)in the dorsal root ganglion(DRG)in a rat model of bone cancer pain.Methods Twenty-four female SD rats,aged 3-4 yr,weighing 180-220 g,were randomly divided into 2 groups:sham operation group(group S,n =8)and bone cancer pain group(group P,n =16).Bone cancer pain was induced by intra-tibial inoculation of 10 μl Walker 256 cancer cell suspension in group P,while group S received intra-tibial inoculation of 5 μl normal saline.Body weight and paw withdrawal threshold to mechanical stimulation with yon Frey filaments(MWT)were measured at 0,1,3,5,7,9,1 1 and 14 d after cancer cell inoculation.The tibia was removed at 14 d after cancer cell inoculation in group S and at 7 and 14 d after cancer cell inoculation in group P for pathological and imaging examinations.The tumor cell growth and bony destruction were observed.The expression of ASIC3 in the DRG was determined by immunolluorescence.Results Pathological damage occurred at 14 d after cancer cell inoculation,bony destruction was observed obviously,ant cortical bone was missing in many places.Compared with group S,body weight at T3-7 and MWT al T2-7:were significantly decreaed,and the expression of ASIC3 was up-regulated at 14 d after cancer cell inoculation in group P(P ＜ 0.05).Conclusion Up-regulation of the expression of ASIC3 in the DRG is involved in the developntent and maiutenence ot bone cancer pain in rars.

Objective To investigate the changes in the expression of acid-sensing ion channel 3 (ASIC3)in the dorsal root ganglion (DRG) in a rat model of bone cancer pain.Methods Twenty-four female Sprague-Dawley rats,aged 3-4 weeks,weighing 180-220 g,were randomized into 2 groups:sham operation group (group S,n =8) and bone cancer pain group (group P,n =16).Bone cancer pain was induced by inoculating Walker 256 carcinoma cells into the medullary cavity of the left tibia,while group S received normal saline instead.The pain threshold was measured after determination of body weight on the day of inoculation (T0) and on 1,3,5,7,9,11 and 14 days after inoculation (T1-7).The tibia was removed for microscopic examination of the inoculated tibia and X-ray examination.The growth of tumor cells and damage to the tibia were observed.The expression of ASIC3 in the DRG was detected using immunofluorescence.Results The tumor cell infiltration occurred in the medullary cavity and bone destruction was observed in P group.Compared with S group,the body weight was decreased at T3-T7,and the pain threshold was decreased at T4-T7,and the expression of ASIC3 in the DRG was upregulated at T7 in P group (P ＜ 0.05).Conclusion ASIC3 protein expression in DRG is significantly up-regulated in the rats with bone cancer pain,suggesting that the pathway may be involved in the mechanism of bone cancer pain.
