Objective: To investigate the effect of polarizing the immune response toward the Th2 type, using intestinal nematode (Trichinella spiralis) infection, on subsequent experimental periodontitis. Methods:Thirty six SPF KM mice were randomly divided into three groups. Periodontitis group: experimental periodontitis was induced by wrapping a 5/0 silk ligature inoculated with putative periodontopathic bacteria around the first maxillary molar. Th2-polaried group: After the mice were infected with low dosage Trichinella spiralis, the experimental periodontitis model was established at that time as above. Mice were sacrificed at the end of 1, 4, 8, 12 weeks. The histological analysis of periodontal tissues was observed by microscope after the samples were stained with hematoxylin and eosin (H&E). The concentrations of IFN--y and IL-4 in mouse serum were determined by ELISA. Results; The results showed that compared with control group Th2-polaried mice had high levels of IL-4 prior nematode infection reduced the severity of periodontitis, and subsequent infection of the periodontium with oral pathogens developed minimal lesions. Few or no osteoclasts were detected in lesions of Th2-polaried group. Conclusion;These results indicate a protective role of nematode infection in Thl cell-driven periodontal damage and prompt consideration of a novel therapeutic strategy in periodontitis based on im-munological distraction.

Objective To investigate the imaging characteristics and diagnostic value of tri-phase dynamic enhancement scan with CT for acute renal infarction. Methods The image features of CT plain scan and tri-phase dynamic enhancement scan of 10 patients (19 sides) with acute renal infarction were retrospectively analyzed, and the CTA expression of 6 patients were observed. Results Fourteen acute renal infarction lesions of 10 cases were diagnosed. The CT scan showed there were 4 cases with enlargement of kidney, and the other 6 cases were of no abnormality. The tri-phase enhancement CT scan showed there were 6 cases of unilateral renal infarction and 4 cases of bilateral renal infarction, which totally involving 14 sides. The acute renal infarction lesions lacked of high density region in the corticomedullary in cortical phase, and there were wedge-shaped hypodense area, even low density of full kidney in parenchymal phase and pyelographic phase. The a-cute renal infarction lesions were revealed better in parenchymal phase and pyelographic phase than in cortical phase. Six cases of CTA re-vealed the responsible vessels of renal infarction lesions and the other vascular diseases. Conclusion CT tri-phase dynamic enhancement scan has important value in the diagnosis of acute renal infarction, and CTA can identify the responsible vessels of renal infarction lesions.

Objective To study the value of carotid plaque magnetic resonance imaging (MRI) in pre-operation assessment in the elderly patients with carotid atherosclerosis and explore the possibility of minimizing the contrast weightings to gain sweeptime. Methods Totally 70 elderly patients with cerebral ischemia (average age of 68.8 years) underwent carotid MRI and digital subtraction angiography (DSA) due to the appearance of carotid plaque detected by ultrasound. Carotid plaque MRI was acquired with 3.0T MR scanner and 8 channel surface coil. The standard carotid plague MRI program included pre-and post-contrast T1 weighted imaging (T1WI), T2 weighted imaging, proton density weighted imaging and 3D time of flight MR angiography (3D TOF MRA). All these program were divided into two combinations: the 5-sequence MRI (all the sequences) and 2-sequence MRI (T1WI and TOF MRA). Digital subtraction angiography (DSA) in coronal and lateral views of carotid artery was performed with GE Advantx LCN+. The software SPSS 13.0 was used to statistically analyze the difference between MRI and DSA, and that of two sequence combinations was used in the detection of luminal stenosis and fibrous cap (FC) rupture. Results Totally 135 arteries were analyzed while 3 arteries in one patient were excluded due to the poor quality image and stent placement. The degree of luminal stenosis were (38.3±31.0)% and (38.5±30.9)%, respectively, detected by the two MRI sequence-combination with no significant difference (t=2.447, P>0.05) and was (35.1±31.8)% by DSA. There was a good concordance between MRI and DSA in luminal stenosis detection (Kappa value: 0.773). No statistical difference was found between two MR sequence combinations in detecting FC rupture (both in 36 vessels). DSA detected FC rupture of 16 vessels, showing remarkably difference contrast to MRI(χ2=12.0, P<0.01). Conclusions MRI can accurately detect the luminal stenosis and FC rupture. The short time scanning resulting from sequence optimization could make MRI much more suitable than DSA to do the pre-operation assessment for senile carotid atherosclerotic patients.

Objective To compare the efficacy of MRI and DSA in assessment of carotid artery stenosis and atherosclerotic plaque.Methods Forty-six patients with carotid plaque detected by ultrasound were enrolled in this study,and 89 carotid arteries were evaluated by MRI and DSA.MRI examination was acquired with 3.0 T MR scanner and 8 channel phase-array surface coil.The MRI sequences consisted of pre-and post-contrast T1WI,T2WI,PDWI,TOF.Anterior-posterior and lateral views of carotid artery were performed on DSA.The degree of carotid artery stenosis was evaluated by the NASCET standard.Fibrous cap rupture,intraplaque hemorrhage,and calcification were also evaluated on MRI and DSA.Statistical comparison was performed with the Kappa value and paired Chi-square test.Results The degree of carotid artery stenosis was 50% (16%-78%) on MRI and 47% (7%-73%) on DSA.Two imaging modalities were in good consistency in evaluation of the degree of stenosis ( Kappa =0.882,P < 0.01 ).There was statistical difference in detecting fibrous cap rupture by MRI and DSA (34 vessels vs 10 vessels,respectively,x2 =20.346,P < 0.01 ).Furthermore,thirty-seven vessels with intraplaque hemorrhage and 71 vessels with calcification in the plaque were found on MRI but none on DSA.Conclusion MRI is a reliable tool in assessment of the degree of the carotid stenosis and it is superior to DSA in detecting fibrous cap rupture,intraplaque hemorrhage,and calcification.

Objective To investigate the effects of different doses of dexamethasone (Dex) on bone mineral density (BMD) and body composition in Sprague-Dawley (SD) rats. Methods Forty 3-month-old female SD rats were divided into four groups:control group (Cont, saline), low dose Dex group (LDG, 1 mg/kg), medium dose Dex group (MDG, 2.5 mg/kg) and high dose Dex group (HDG, 5 mg/kg). Ten rats for each group. Dex was injected intramuscularly twice a week. The values of BMD and body composition were measured by DEXA densitometer at the beginning and 4-week of treatment. Results The body weights of different doses of Dex intervention groups were decreased after 1 to 4-week intervention compared with those of Cont group (P<0.01). After 4-week intervention, the total BMD, femur BMD, total bone mineral content (BMC), to-tal fat mass, trunk fat mass and leg fat mass were significantly increased in Cont group (P<0.01), while the total lean mass, trunk lean mass were significantly decreased (P<0.01). The total BMC, femur BMD, leg lean mass, leg fat mass were signifi-cantly lower in LDG group and MDG group than those of Cont group (P<0.05). The femur BMD, leg fat mass were signifi-cantly lower in LDG group and MDG group than those of HDG group (P<0.05). Conclusion The doses of 1 mg/kg and 2.5 mg/kg Dex have greater impact on the femur BMD and the leg composition in SD rats than that of Dex (dose of 5 mg/kg ).

Objective To study the changes of phosphatidylcholine-specific phospholipase D (PC-PLD) enzyme activity of glomerular mesangial cells (GMCs) in high glucose and the effect of PLD on cytoskeleton. Methods Rats GMCs were cultured in high glucose(30 mmol/L) for 48 hours. PLD enzyme activity was measured by enzyme coupled colorimetry. PKC activity was measured by substrate phosphorylation, and fluorescence intensity of F-actin was observed by FITC-labeled antibody and laser scan cofocal microscopy (LSCM) . Results In high glucose, PLD and PKC activities were obviously elevated, but fluorescence intensity of F-actin was decreased and its cytoskeletal pattern was disassembly. After treatment with inhibtor of PLD, PKC activity was significantly decreased, and intensity and organization of F-actin were recovered. Conclusion Elevation of PLD activity induced by high glucose may influence the cytoskeleton and contraction of CMC through PKC pathway.
