Objective To establish diagnostic models for pancreatic carcinoma(PC)and to find out the biomarkers related to PC.Methods Serum samples obtained from subjects including PC patients,pancreatic benign disease patients and normal controls were examined with strong anionic exchange chromatography(SAX2)chips for protein profiling using surface enhanced laser desorption/ionization-time of flight-mass spectrometry(SELDI-TOF-MS).The decision tree models and logistic regression models for evaluating the value of serum biomarkers were assessed.SELDI immunoassay and ELISA were used to identify the biomarker and its level in serum respectively.Results Twentysix mass peaks were different between PC patients and normal controls(P＜0.0 1)and 16 mass peaks were different between patients with PC and with pancreatic benign disease(P＜0.05).The decision tree model had a sensitivity of 83.3%and a specificity of 100.0%in differentiation of PC,which was better than that of CA19-9 by ROC curve.There were significant differences in 6 mass peaks among different stages of PC(P＜0.01).Logistic regression model showed a sensitivity of 81.6%and a specificity of 80.6%in diagnosis of early PC.The M/Z 28068 protein was identified as C14orf166 with a sensitivity of more than 82%and a specificity of more than 88%in diagnosis of PC.Conclusions The diagnostic models based on SELDI-TOF-MS were superior to CA19-9 in diagnosis of PC.The identified biomarker C14orf166 is expected to play a role in the diagnosis of PC.

OBJECTIVETo study the diagnosis of vasovagal syncope (VVS) in children with postural orthostatic tachycardia syndrome (POTS).

METHODSThe clinical data of 57 children with POTS diagnosed by the head-up tilt test between January 2007 and December 2010 were studied retrospectively. Of the 57 children, there were 29 boys and 28 girls who were aged from 5 to 16 years (12.2±1.9 years).

RESULTSTwenty-four (42%) out of 57 children were diagnosed with VVS by prolonging the duration of the head-up tilt test (for the children with orthostatic tolerance): cardioinhibitory (20 cases), mixed (3 cases) and vasoinhibitory (1 case). The POTS children with VVS were older than those without (13.0±1.4 years vs 11.5±2.1 years; P<0.05). There were no significant differences in gender and clinical symptoms between the POTS children with and without VVS.

CONCLUSIONSSome children with POTS may have coexisting VVS, suggesting that it is important to avoid misdiagnosis of VVS by prolonging the duration of head-up tilt test in POTS children with orthostatic tolerance. There are no obvious differences in gender and clinical symptoms between the POTS children with and without VVS.

OBJECTIVEIn order to investigate the roles of metalloproteinase in inflammatory bone destruction in ankylosing spondylitis (AS), and analyze the mechanism of preventing inflammatory bone destruction of Bushen Qiangdu decoction (BSQDD) in AS cases. Comparisons were made on the expressions of matrix metalloproteinase 9 (MMP-9) and tissue inhibitor of metalloproteinase 1 (TIMP-1) by peripheral blood mononuclear cells (PBMC) between AS patients and healthy controls. The effect of BSQDD was investigated on the expression and of MMP-9 and TIMP-1 produced by PBMC in AS patients.

METHODSFrom March 2005 to March 2006, 30 active AS cases of Kidney-asthenia, Du-cold and blood-stasis syndrome were selected as patients group in the China-Japan Friendship Hospital. There are 27 male patients and 3 female patients. The age range is from 16 to 45, averaging (30.8 +/- 8.8) years. Disease duration is from 0.5 to 10 years. Cases received three-month BSQDD treatment were considered as the treatment group. Twenty healthy persons were included in the control group. Serum and PBMC were separated. The PBMC were stimulated by PHA and PMA, and the supernatant was collected. The mRNA expression of MMP-9 and TIMP-1 in PBMC was analyzed by RT-PCR. The content of MMP-9 and TIMP-1 in serum and culture supernatant of PBMC were detected by ELISA.

RESULTSCompared with health control group, the serum concentration of MMP-9 and TIMP-1 in patients group before treatment increased (P<0.01, P<0.05), but the level of MMP-9 and TIMP-1 in the serum of patients after treatment decreased compared with pre-treatment cases (P<0.05). Furthermore,compared with health control group, PBMC of patients group before treatment expressed higher levels of MMP-9 and TIMP-1 both on transcript level and at protein level (P<0.01, P<0.05), and the expression levels of MMP-9 and TIMP-1 in PBMC in patients after treatment both on transcript level and at protein level was down-regulated compared with pre-treatment (P<0.01, P<0.05).

CONCLUSIONPBMC of AS patients had a higher potential capacity for MMP-9 and TIMP-1. BSQDD possibly prevented inflammatory bone destruction of AS through inhibiting production of MMP-9 and TIMP-1 produced by PBMC.

OBJECTIVETo evaluate the effect of decoction for invigorating the kidney and improving blood circulation to thrombosis on rabbits blood stasis model.

METHODThirty rabbits were randomly divided into normal group, model group, heavy dose group, slight dose group and xue shuan ning group. Tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor (PAI), fibrinogen (Fbg) and D-dimer (DD) were investigated after those rabbits had been treated. One was selected randomly from each group to observe pathological changes.

RESULTThere was significant difference in t-PA, PAI, Fbg and DD between normal group and other groups (P < 0.01). Among groups of heavy dose, slight dose, xue shuan ning and model, the statistical differences were significant, as well as among groups of heavy dose, slight dose and xue shuan ning (P < 0.05). However, there was no statistical difference between heavy dose group and slight dose group (P > 0.05). The pathological changes in model group were most serious, and those in xue shuan ning were less serious. There were slight pathological change in heavy dose group and light dose group.

CONCLUSIONModels were made successfully. Heavy dose group and slight dose group have stronger effect on thrombosis than xue shuan ning group.

OBJECTIVE: To investigate the anti-tumor effects and the mechanism of the recombinant fowlpox virus expressing Apoptin gene on human laryngeal carcinoma Hep-2. METHOD: Hep-2 cells cultured in vitro were infected with vFVApoptin. The anti-tumor effects on Hep-2 cells were measured through MTT staining and, the mitochondrial trans-membrane potential (delta psi m) and reactive oxygen species (ROS) were analyzed by flow cytometry. Western blot was used to detect the release of cytochrome c (Cyto c). Caspase-3/9 activities were measured by colorimetric assay. RESULT: vFVApoptin could restrain Hep-2 cells significantly and, had the function of down-regulating delta psi m, up-regulating ROS, promoting Cyto c release and activating Caspase-3/9. CONCLUSION Cyto c were released from mitochondria by the function of up-regulating ROS of vFVApoptin. Cyto c triggered Caspase-9 and, after the activation of Caspase-9, downstream apoptotic factors, such as caspase-3, were activated. Eventually, Hep-2 cells were suppressed by mitochondrial pathway apoptosis induced by vFVApoptin.

OBJECTIVETo investigate the fibrogenetic effects induced by rush-mat dust in rats.

METHODSSD rats were treated with 50 mg of rush-mat dust per rat by intra-tracheal instillation, sacrificed 3, 6, and 12 months respectively after exposure. The lung tissue and lung lymph-node were taken out for pathological and electron microscopic examination. The content of collagen and ceruloplasmin (CP) in lung tissues were also determined.

RESULTSAfter treatment for 12 months, fresh wet lung weight in rush-mat dust group [(2.69 +/- 0.22) g] was higher than those in saline group [(1.87 +/- 0.25) g], TiO(2) group [(2.25 +/- 0.26) g], but lower than that in SiO(2) group [(11.41 +/- 1.63) g]; dry lung weight in rush-mat dust group [(0.47 +/- 0.03) g] was higher than those in saline group [(0.32 +/- 0.03) g], TiO(2) group [(0.41 +/- 0.08) g], but lower than that in SiO(2) group [(2.06 +/- 0.28) g]; lung collagen content in rush-mat dust group [(103.08 +/- 14.79) mg] was higher than those in saline group [(75.96 +/- 13.91) mg, TiO(2) group [(85.84 +/- 17.62) mg], but lower than that in SiO(2) group [(497.50 +/- 100.80) mg]; CP content in rush-mat dust group [(18.03 +/- 1.87) U/L] was higher than those in saline group [(15.05 +/- 2.24) U/L], TiO(2) group [(16.92 +/- 1.67) U/L], but lower than that in SiO(2) group [(25.37 +/- 3.58) U/L], P < 0.05 or P < 0.01. Pathological examination showed lung macrophage alveolitis, broadening of alveolar interval, one to two grade of silicotic nodes and increased amount of type II epithelial cell in alveolar as well as slight collagenous fibrosis in lung tissue of rush-mat dust group. Under electron microscope, primary and secondary lysosome and medullary sheath-like phagocytic residual body were found in lung tissue of rush-mat dust group, meanwhile the amount of type II alveolar epithelial cell and collagen fiber were slightly increased but these changes were less than those of quartz group.

CONCLUSIONThe rush-mat dusts have slight pulmonary fibrogenetic effect on rat.
