Pancreatic stone protein (PSP) is the product of exocrine pancreas mainly synthesized and secreted by the pancreas acinar cells, a small amount secreted by gastrointestinal cells. PSP is one of stress protein family members secreted in the pancreas. PSP increased in acute and chronic pancreatitis, diabetes, inlfammatory bowel disease and gastrointestinal tumors. In recent years, some studies showed that PSP has potential clinical value in pancreatic injury and sepsis. In this article, we reviewed the progress of pancreatic stone protein in pancreatic injury and sepsis.

BACKGROUND:The stress distribution in the periodontal ligament of bending root can provide reference for the size and manner of force in orthodontic treatment. On this account, it can optimize the design of orthodontic force. OBJECTIVE:To analyze the stress distribution of root and periodontal ligament in the bending roots of the
maxil ary first molar under different orthodontic forces.
METHODS:The maxil ary first molars with normal roots and bending roots were selected, and then the finite element models of maxil ary first molars and periodontal ligaments were established through CT scan and
Workbench 11.0 finite element analysis software. The models were loaded with six different methods to analyze the stress distribution.
RESULTS AND CONCLUSION:The stress distribution of bending root was mainly concentrated in the tooth
neck, fol owed by the apex. During the overal tooth movement, the stress was smal est on the root, periodontal ligament and alveolar bone. Correction of bending roots needs more accurate positioning and traction.

Objective To discuss the foreground of application of reverse engineering reconstruction of dental models and to establish the foundation of developing a system for complete denture CAD/CAM. Methods The models of an edentulous jaw were measured with reverse engineering, and the 3D models were reconstructed with a computer. Results 3D models of the edentulous jaw were achieved. The characteristics of these 3D images were clear and accurate. Conclusion CAD models are reconstructed with reverse engineering accurately and technical problems in 3D model of complete denture CAD/CAM are resolved.

Objective:To examine the expression pattern of DSP,DMP1,CBFA1,BMP2 in rat dental pulp stem cells(RDPSCs).Methods:Immunohistochemical staining was carried out using antibodies against DSP,DMP1, CBFA1 ,BMP2 in rat dental pulp stem cells. Mineralization was induced in the RDPSCs and expression of DSP and DMP1 was measured after induction.Results:CBFA1 and BMP2 were positive in RDPSCs. Only a few RDPSCs were stained positive for DMP1. DSP expression was observed in the minority of these cells. However, the majority of the RDPSCs were found strongly positive for DSP and DMP1 after mineralization induction.Conclusion:Positive expression of CBFA1 and BMP2 indicates the premature nature of RDPSCs. The dentin-specific expression of DSP demonstrates that the RDPSCs can differentiate along odontoblastic lineage.

Background The impact of statins on inflammation are independent of cholesterol-lowering effect.Recent studies showed that Toll-like receptor 4(TLR4),a mediator of innate immune responses,is involved in the initiation and progression of atherosclerosis.Objective To investigate the effects of atorvastatin on LPS-induced TLR4 expression and downstream signals and to explore the molecular mechanisms of anti-inflammation by statins.Methods Human umbilical vein endothelial cells(HUVEC)were pretreated with atorvastatin(1 or 10 ?mol/L)or NF-?B inhibitor CAPE for 30 min,then incubated by purified LPS for 24 hours.TLR4,ICAM-1 and E-selectin mRNA were measured by RT-PCR;the percentage of TLR4 positive cells were detected by flow cytometry.The activation of NF-?B(p65)were detected by Western blot.Results Atorvastatin(1-10 ?mol/L)prevented LPS-induced increases in TLR4,ICAM-1 and E-selectin expression [TLR4 mRNA(1.24?0.21)vs LPS(1.82?0.27),P

Visualization of medical images has become an important method for the basic medical research as well as clinical diagnosis and treatment.Construction of the highly sophisticated three-dimensional(3D) models of the human body by computers has become an essential foundation for current medical research and disease treatment methods.Visualization Toolkit(VTK) is a kind of famous software in scientific visualization fields.It is convenient and efficient for programming.This paper implements three typical algorithms,Contour-connecting,Marching Cubes and Ray-casting,of medical image 3D visualization using VTK with VC++.Results show that VTK is a powerful tool with many advantages,such as simple operation,fast,and good interaction ability and can be widely used in 3D reconstruction of medical images.

Objective To investigate whether ornithine decarboxylase antizyme inhibitor-1(OAZI-1) can enhance the immunogenicity of Melan-A and induce antitumor immune effect in the experimental animals.Methods The eukaryotic expression plasmid pcDNA3.1(-) /OAZI-1, pcDNA3.1 (-)/Melan-A and pcDNA3.1(-)/Melan-A-OAZI-1 were constructed and used to immunize BALB/c mice.The spleen lymphocytes were prepared from the immunized mice and then used to determine the lymphocyte subsets by flow cytometry assay and tumor-killing activity by LDH release assay.The blood samples were collected from the immunized mice and used to test the serum INF-γ by ELISA.Results The eukaryotic expression plasmid pcDNA3.1(-)/OAZI-1, pcDNA3.1(-)/Melan-A and pcDNA3.1(-)/Melan-A-OAZI-1 were successfully constructed.All three gene vaccines could increaseCD4+ T cell ratio (P<0.05), among of them, the ratio in the pcDNA3.1(-)/Melan-A-OAZI-1 and pcDNA3.1(-)/Melan-A immunized groups increased more significantly than other groups but no obvious differences was observed between these two groups.Similarly, all three gene vaccines could also increased CD8+T cells ratio significantly (P<0.05), but, comparing with all other groups, the highest increase was observed in the pcDNA3.1(-)/Melan-A-OAZI-1 immune group (P<0.05).The pcDNA3.1(-)/Melan-A-OAZI-1 gene vaccines significantly increased cytotoxic activity of the spleen lymphocyte in the immune mice(P<0.05).Among the three gene vaccines only pcDNA3.1(-)/Melan-A-OAZI-1 could significantly increased the INF-γ level in the mice serum (P<0.05).Conclusions OAZI-1 can improve antitumor immunity by promoting tumor antigen presentation.

ObjectiveTo explore the value of elevated amylase in assessment of severity of the disease and its inlfuencing factors in critically ill children.MethodThe clinical data from critically ill children hospitalized in pediatric intensive care unit were retrospectively analyzed from November 2009 to June 2014. According to levels of serum amylase, the critically ill children were divided into normal serum amylase group (≤103 IU/L) and elevated serum amylase group (>103 IU/L). The differences between two groups were compared.ResultsA total of 1920 critically ill children were enrolled, most of whom had primary respiratory and neurological diseases. Among them, 1470 children had normal serum amylase (76.6%) and 450 children had ele-vated serum amylase (23.4%). The elevated serum amylase group had signiifcantly higher rate of organs failure (≥4), lower rate of PCIS (<70), higher rate of invasive mechanical ventilation and mortality than those in normal serum amylase group (P<0.001). The correlation of serum amylase with lipase blood, urine amylase, blood urea nitrogen and creatinine were signiifcant (r=0.246 to 0.683,P<0.001). Blood amylase was positively correlated with shock index (r=0.111,P=0.002) and negatively correlated with respiratory failure index (r=0.133,P<0.001).ConclusionsSerum amylase could be used to assess the severity of disease. The elevated amylase was closely related to pancreatic exocrine function, renal function, ischemia, and hypoxia. The elevated serum amylase in critically ill children is a warning sign.
