Objective To investigate the feasibility of induction of experimental chronic pancreatitis rat model with L-arginine.Methods Animals were randomly divided into control group,arginine 12 h group,arginine 24 h group and arginine 7 d group with 10 rats in each group.L-arginine solution was intraperitoneally injected twice with an interval of 1 h.Serum amylase and glucose levels at corresponding time points were detected and histopathological scores of pancreas were evaluated.Collagen in pancreas was stained with Van Gieson method.Results Serum amylase levels were (1 634±890 ) U/L,( 3 872±2 676 ) U/L,( 3 307±2 197)U/L and (1 561±304) U/L in control group,arginine 12 h group,arglnine 24 h group and arginine 7 d group,respectively.The serum amylase level in arginine 7 d group was significantly lower than those in arginine 12 h group and arginine 24 h group (P ＜ 0.05 ).There was no significant difference in serum glucose level among all the groups.Histopathological scores were 0.8±0.4,5.1±2.6,6.5±2.2 and 4.5±1.6,respectively.The histopathological score of arginine 7 d group was significantly lower than those in arginine 24 h group (P ＜ 0.05 ).Obvious collagen could be found in pancreatic parenchyma in arginine 7 d group,while little collagen was found in pancreatic tissue in control,arginine 12 h and arginine 24 h groups.Conclusions Injection of L-arglnine induced fibrosis in pancreatic parenchyma and proliferation of tubular complex 7 days later,and it could be used for chronic pancreatitis model induction.

OBJECTIVETo investigate three-dimensional changes of maxilla after rapid maxillary expansion (RME).

METHODSTen patients treated with RME were included in the study. Spiral CT images were used to evaluate three-dimensional changes of the maxilla. A three-dimensional reference frame was set up.

RESULTS(1) ANS, PNS' and PNS displaced downward and forward. ANS-PNS plane rotated clockwise in the mid-sagittal plane. ANS-PNS' plane, which represents the real position of maxilla, was not changed in the mid-sagittal plane. The palatal suture was expanded in taper shape and two halves of the maxilla rotated in the frontal plane. (2) The maxillary suture was opened wider in the middle and narrower at both ends, which was like a spindle.

CONCLUSIONSThree-dimensional changes were found after RME treatment. Spiral CT was useful in the three-dimensional evaluation of maxilla.

Purpose: The purpose of the present study was to investigate the effects of image matching experience of operators on the accuracy and working time of image registration between radiographic and optical scan images. Materials and Methods: Computed tomography and optical scan of a dentate dental arch were obtained. Image matching between the computed tomography and the optical scan (IDC S1, Amann Girrbach, Koblah, Austria) was performed using the point-based automatic registration method in planning software programs (Implant Studio, 3Shape, Copenhagen, Denmark) using two different experience conditions on image registration: experienced group and inexperienced group (n = 15 per group, N = 30). The accuracy of image registration in each group was evaluated by measuring linear discrepancies between matched images, and working time was recorded. Independent t test was used to statistically analyze the result data (α = .05). Results: In the linear deviation, no statistically significant difference was found between the experienced and inexperienced groups. Meanwhile, the working time for image registration was significantly shorter in the experienced group than in the inexperienced group (P = .007). Conclusion Difference in the image matching experience may not influence the accuracy of image registration of optical scan to computed tomography when the point-based automatic registration was used, but affect the working time for the image registration.

Objective To evaluate the influence of tissue factor pathway inhibitor 2(TFPI-2)gene on the proliferation and invasion of K562.Methods The expression vector pcDNA3.0/TFPI-2 was transfected into human leukemia line K562 cells(K562-T)by using liposome,then the mRNA and protein TFPI-2 were detected by real-time RT-PCR and western blot separately.The growth curve and the colony-forming unit assay were used to measure the ability of cells growth and transwell chamber model was employed to test the ability of cell invasion in vitro.Results Expression of mRNA and protein of TFPI-2 was detected in transfected cells.The growth rate and self-replication ability of K562-T cells were lower than those of the two control groups obviously.The number of K562-T cells to traverse a Matrigel-coated membrane was dramatically decreased compared with that of non-expressing cells.Conclusion The gene of TFPI-2 can inhibit the growth,proliferation and invasion of the K562 cells.
