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 study the intervention effect of tanshinone on electrophysiological abnormality of hypertrophic cardicoyte in order to illuminate the underlying mechanism of tanshinone in preventing the arrhythmia induced by myocardial hypertrophy. Method Twenty-week-rid SD rats (200～250 g) were divided into 4 groups (8 in each group) randomly. Of 4 groups, rats of three groups were operated on by a procedure of 'one kidney one clamp' to make renal artery constriction. The rest group served as sham operation group (control group). When the blood pressure increased,rats of operation groups were divided into tanshinone group, captopril group and hyper-trophic group. The effects of tanshinoe and captopril were observed and compared on the action potential duration (APD),L-type calcium current (ICa, L) and transient outward potassium current (Ito) density in cellular membrane of hypertrophic myocardium by using patch clamp and intra-cellular calcium survey technique. Results The blood pressure in operation groups was obviously higher than that in sham-operation group (P<0.01), but there was no difference between operation groups (P>0.05). The ratio of ventricle weight to body weight (VW/BW) was much higher in hypertrophic group than in control group (P<0.01), and it significantly decreased after interven-tion with tanshinone or captopril (P<0.01). Compared with hypertrophic group, tanshinone markedly shortened the prolongation of action potential duration (P<0.01), decreased membrane capacity and peak amplitude of ICa,L(P<0.01), but had no effect on the density of ICa,L. Tanshinone also significantly increased Ito current density and peak amplitude, which were completely different from hypertrophic group (P<0.05). There were similar results foundin captopril intervention. Conclusions Tanshinone could reduce calcium influx and resume the activity of ho ion channels, and thus shorten the first phase and the plateau phase of repolarization and decrease the prolongation of APD in hypertrophic cadiocyte. So tanshinone can prevent the onset of arrhythmia attributed to the myocardial hypertrophy.

0.05). Conclusion:The excessive expression of Survivin in gallbladder cancer indicates that Survivin could be not only correlated with the occurrence of carcinoma but an early and common event in gallbladder carcinogenesis. Surviv in will promisingly become a novel tumor marker and can be applied in the clinic al practice for helping the early diagnosis as well as targeting gene therapy fo r gallbladder cancer.
