Objective To analyze differentially expressed genes between hilar and distal cholangiocarcinoma and to clarify the molecular mechanism of tumorigenesis. Methods Gene-expression profiles of 3 samples of hilar cholangiocarcinoma and 4 samples of distal cholangiocarcinoma were analyzed using oligo microarray containing 21 329 genes. The differentially expressed genes between the two groups were analyzed using the Significance Analysis of Microarrays (SAM) in order to get the specifically differentially expressed genes. The gene expression presence was verified by real-time PCR (RT-PCR). Results A total of 725 genes of cholangiocarcinoma was regulated significantly compared to normal bile duct. Of them, 244 genes were upregulated and 399 genes were downregualted in both groups; on the other hand, 82 gene expressions between hilar and distal cholangiocarcinoma had significant differences (ratio ≥ 2.0 or ≤ 0.5). The SAM analysis showed that 40 genes, including AREG, EPHA2, SPP1, PACE4, and so on, were identified as differentially regulated between the two groups (q=0). Conclusions These data are helpful for a better understanding of the tumorigenesis of cholangiocarcinoma and contribute to the development of diagnostic and therapeutic strategies. The gene expressions between hilar and distal cholangiocarcinoma are significantly different, which suggests that the two tumors have different molecular mechanisms of tumorigenesis.

Objective To observe the inflammatory state and residual renal function (RRF) of the patients with maintenance hemodialysis treated through Shenkangling. Methods Sixty patients with maintenance hemodialysis were randomly divided into two groups, the observation group (30 cases) and the control group (30 cases). They were treated through hemodialysis and hemodiafiltration. The patients in the observation group were treated with Shenkangling 8 tablets/time, 3 times/day. RRF and urine volume after six months were evalued. Serum high-sensitivity C reactive protein (hs-CRP), tumor necrosis factor alpha (TNF-α), and leukocyte mediated IL-6 (IL-6) before and after treatment were detected. Results There were no statistical differences in RRF and urine volume between the two groups before treatment (P>0.05). After six months, RRF and urine volume in the two groups were significantly reduced (P<0.05), and those of the observation group were significantly higher than those of the control group (P<0.05). There was no statistical significance in serum hs-CRP, TNF-α and IL-6 between the two groups before treatment (P>0.05). After treatment, the serum levels of hs-CRP, TNF-α, IL-6 significantly decreased in the observation group, and lower than those of the control group (P<0.05). Conclusion Shenkangling can protect the residual renal function of hemodialysis patients, and reduce the inflammatory reaction.

Objective To explore the clinical features of systemic onset of juvenile idiopathic arthritis (SoJIA) with atlantoaxial subluxation as the initial manifestation. Methods The clinical data from one SoJIA patient with atlantoaxial subluxation as the initial manifestation were retrospectively analyzed. Results A 9-year-old boy presented the head and neck movement disorder as the ifrst symptom, developed fever on the third day, then rapidly progressed on 23rd day, with a sharp decline in red blood cell, platelet, and hemoglobin, blood coagulation dysfunction, and a large number of bilateral pulmonary exudation. Ultrasonography showed excess lfuid in abdomen, chest, and pericardium. According to the 2001 version of the revised International College of Rheumatology standard, the diagnosis of SoJIA combined macrophage activation syndrome was conifrmed. Then treated with hemoperfusion, ifltration, and methylprednisolone combined with cyclosporine A, the disease was in remission. Conclusion For children with spontaneous atlantoaxial subluxation accompanied by the systemic symptoms, with no obvious skeletal deformity or acute inlfammation etc., should be alerted to the consideration of systemic juvenile idiopathic arthritis.

Objective To investigate the current status of coal-burning endemic fluorosis and the fluoride content in foods and drinking water in Hongya County,Sichuan Province.Methods Dental fluorosis and urinary fluoride were suveyed in children of 8～12 years old in two schools which repectively located in Gaomiao and Wawushan Town.The adults above 20 years old underwent clinical examination.At the same time,fifty adults above 20 years old in Garden Village were chosen to take forearm and calf X-ray films to find out the evidence of skeletal fluorosis.The content of fluoride in food such as bacon,corn,dry capsicum in Sanxing Village in Gaomiao Town and Futian Village in Wawushan Town as well as drinking water in five families in Sanxing Village were determined.Results The dental fluorosis rate of children was 40.76%(161/395),the dental fluorosis index was 0.86 in Gaomiao Town.The dental fluorosis rate of children was 14.36%(82/571),the dental fluorosis index was 0.31 in Wawushan Town.The medium value of the urine fluoride was 0.81 mg/L.ranged 0.16～3.89 mg/L.The positive rate oi the clinical examination of skeletal fluorosis was 5.27%(27/512),the X-rays detective rate was 4.00%(2/50).The medium value in bacon,corn,dry capsicum were 6.00,0.64,1.49 mg/kg.The averaged content of the fluoride in drinking water(0.14±0.06)mg/L of local household was within the eligible limitation.Conclusions It is currently a mild endemic disease in Hongya Country,its incidence is reduced apparently,pathogenetic environmental fluoride content is reduced.The main source of fluoride is from the preserved ham contaminated with fluoride,which is epidemiologically significant in endemic area of Hongya County.Defluoriding countermeasures should be taken in the endemic areas.

Objective To evaluate the application effect of evidence-based care model in hemostasis by compression in patients after renal biopsy.Methods 80 patients undergoing renal biopey from December 2006 to December 2009 in our hospital were chosen as the research object.They were randomly divided into the control group and the observation group with 40 patients in each group.The control group was given routine nursing,and the observation group was treated with evidence-based care model for nusing.The re-bleeding rates,satisfaction degree and the SAS,SDS score,mastering degree of related knowledge,treatment compliance for the two groups before and after nursing were compared.Results The ineidence rate of bleeding in the observation group was higher than the control group,satisfaction degree was higher,and the SAS,SDS score,related knowledge,treatment compliance were all better than the control group,there were significant differences.Conclusions The effect of evidence-based care model in hemostasis by compression after renal biopsy is better.It can significantly reduce the incidence of adverse circumstances and improve the negative emotional state of patients.

0.05).Conclusion High level of Blys could be observed in serum of patients with SLE and somewhat correlated with the lupus acitivity,although the level of Blys in serum can not reflect morbility and mortality of SLE patients.

AIM: Using functional magnetic resonance imaging, to inspect v sual cortex physical reactions stimulated by rotating grating, and to its components. METHODS: On 1.5T MR scanner, GRE-EPI imaging sequence was carried on 9 h discover ealthy volunteers, the visual cortex response data were processed after delinearation by SPM99.RESULTS: Different components of rotating grating excited different areas of the visual cortex. Dramatic response in the central part of the occipital lobe, which was related to white light stimuli, located at primary visual cortex. Response area in bilateral Broadaman 19 areas was related to vision-motion function. And weak response area in the central part of the occipital lobe was related to shape perception.CONCLUSION: Rotating grating conclude plenty of visual information, and it excites different areas of the optic center as a stimuli. fMRI is a valuable equipment to study the physiology of visual cortex.
