Objective:To investigate the expression of dental matrix protein 1(DMP1)in carious human permanent teeth and its possible role during the reparative process after pulp injury.Methods:10 of noncarious third molars (NC),10 of shallow carious (SC),10 of intermediate carious (IC) and 10 of deep carious (DC) were prepared for the detection of DMP1 in odontoblasts by immunohistochemical staining. DMP1 expression in odontoblasts was analyzed by image analysis system and expressed as integral optical density (IOD).Results:DMP1 was majorly detected in cytoplasms and processes of odontoblasts and odontoblast-like cells.The IOD values in the groups of NC,SC,IC and DC were 0.265?0.018,0.309?0.021,0.678?0.031 * and 0.691? 0.033 * respectively;that in the reparative dentin in DC group was 0.856?0.045 ** ( *vs NC P

In order to estimate the relationship between iron and the Alzheimer's disease, the behavioral and pathological changes were observed by Morris water maze and immunohistochemical staining respectively after injecting FeC13 into brain ventricle of rats. The apoptosis was tested by flow cytometry and the electron microscopy was used to observe ultrastructural changes. There were significant differences in escape latency of time and distance between normal animals and iron treated rats. Percentage and fluorescence intension (FI) of AnnexinV FITC loaded cells undergoing apoptosis were higher in iron treated rats compared with normal animals. Fawn-coloured products of β amyloid protein were interspersedly distributed in extensive areas of cerebral cortex and hippocampus. Under electron microscope, vacuolate degeneration of neuronal processes with mitochondria degeneration and accumulation of microtubule near vacuolar nucleus were observed in iron treated rats. These results suggest that a local higher concentration of iron in brain may induce Alzheimer-like impairment of intelligence and pathological changes.

Aim To evaluate the effects of ferulic acid ( FA ) on lipopolysaccharide ( LPS )-induced neuroin-flammation in microglia cells and its potential mecha-nisms. Methods Microglial activation was induced by stimulation with LPS, and the effects of FA pretreat-ment on microglial activation and production of proin-flammatory mediators, nitric oxide/iNOS were investi-gated. The role of the mitogen-activated protein kinases in the antiinflammatory actions of FA in LPS-stimulated microglia was further elucidated. Results Cell viabil-ity experiments revealed that FA did not produce cyto-toxicity in microglia. FA significantly inhibited LPS-in-duced production of tumour necrosis factor-alpha ( TNF-α) , interleukin-6 ( IL-6 ) , interleukin-1 beta ( IL-1β) , and nitric oxide ( NO ) . Protein and mRNA levels of COX-2 and inducible nitric oxide synthase ( iNOS) were also attenuated by FA. Further experi-ments on intracellular signalling mechanisms showed that inhibition of extracellular regulated kinase ( ERK) contributed to the anti-neuroinflammatory actions of FA. Conclusion The results suggest that FA inhibits LPS-induced microglial inflammation by partial targe-ting of ERK signalling and attenuation of ERK.

OBJECTIVE: To learn the clinical features of patients infected with Klebsiella pneumoniae in our hospital.METHODS: From 2006 and 2007,a total of 96 inpatients in our hospital that were confirmed to be infected with Klebsiella pneumoniae by sputum culture were collected for a study of their clinical features and drug susceptibility test results.RESULTS: Patients with Klebsiella pneumoniae infection represented 12.7% of the total concurrent pulmonary infection cases,of which,57 Klebsiella pneumoniae infection cases had concurrent pulmonary tuberculosis(TB),and 39 Klebsiella pneumoniae infection cases had no concurrent TB.Drug susceptibility tests showed that the resistance rates of Klebsiella pneumoniae to third generation cephalosporins and quinolones were higher than those reported in the literature,and the resistant rate of Klebsiella pneumoniae to quinolones in Klebsiella pneumoniae infection patients complicated with TB was higher than those without TB.CONCLUSION: Klebsiella pneumoniae infection was more common in patients with low body resistance,which has typical clinical manifestations.Recently,the resistance of Klebsiella pneumoniae to the third generation cephalosporin has been increasing,and its resistance to quinolones in patients with pneumonia Klebsiella infection complicated with TB was significantly higher than in those without TB.

Radiological evaluation is a key step for donor's preoperative evaluation in living donor liver transplantation(LDLT).There are many powerful functions in multi-slice computed tomography (MSCT)which can suit all-in-one radiological evaluation before donor's operation.By referring to the articles from home and abroad in recent years,from viewpoint of surgeon,this artical reviews the application status of multi-slice CT for preoperative assessment in LDLT,which can help to provide theory support for choice of radiological examination in LDLT donor.

Objective To explore the value of helical computed tomography (CT) in differential diagnosis of xanthogranulomatous cholecystitis (XGC) and wall-thicked gallbladder cancer (GBC).Methods The CT signs of 18 XGCs and 20 wall-thicked GBCs were retrospectively analyzed.The maximum thickness of gallbladder wall, intramural hypoattenuated nodules, mucosal line of gallbladder inner wall,patterns of enhancement of thickened wall,whether combined with stones,the pericholecystic adjacent liver tissue involvement and biliary tract obstruction were observed.Measurement data were analyzed by independent sample t test and count date were analyzed by Fisher precisely the probability method.Results The mean maximum thickness of the gallbladder wall of XGC and wall-thicked GBC was (22.11±10.19) mm and (20.55±7.94) mm respectively,and there was no statistical significance (t=0.530,P=0.600).Eighteen cases of XGC and five cases of wall- thicked GBC patients were with intramural hypoattenuated nodules (Fisher precisely the probability method,P＜0.01 ),14 cases of XGC and six cases of GBC were with integrated mucosal line (Fisher precisely the probability method,P =0.004 ),three cases of XGC and 12 cases of GBC were with biliary tract obstruction (Fisher precisely the probability method,P=0.009).There was no statistical significance in the CT signs of the range of wall thickness,patterns of enhancement and enhanced degree of thickened wall,adjacent liver tissue involvement, lymphadenopathy, combined with gallbladder or bile duct stone between XGC and wall-thicked GBC patients (Fisher precisely the probability method,all P ＞ 0.05).Conclusions The thickened gallbladder wall with intramural hypoattenuated nodules and integrated gallbladder inner wall mucosal line were characteristic signs for diagnosing XGC.Helical CT scanning can provide evidence for differential diagnosis in XGC and wall- thicked GBC.

Objective To discuss the diagnostic value of peritoneal effusion detection by emergency-ultrasound in patients with closed abdominal injury. Method From August 2006 to June 2009,212 patients with closed abdominal injury were studied to evaluate peritoneal effusion detection by emergency ultrasound. Results of 212 patients,peritoneal effusion frequency rate was 78.8%( 167/212), meanwhile,abdominal paracentesis confirmation ratio was only 46.2%(98/212). In the follow-up, 13 patients with injuried hollow viscera and 1 patient with rupture of kidney showed peritoneal effusion. The volume of abdominal fluid was increasing in 17 patients,which needed to be managed by surgery. The accuracy rates were respectively 78.3%( 112/143) and 36.1%(13/36) in the solid organs and the hollow organs. Conclusion During the course of diagnosis and treatment in closed abdominal injury,peritoneal effusion monitoring by ultrasound should be used routinely, which can help to decrease the rate of misdiagnosis and avoid delayed treatment.
