The distribution of TrkA and the postnatal development(PD) of TrkA and ChAT-immunoreactive(-IR) neurons andthe relation between them in the basal nucleus of Meynert of rats were studied with immunohistochemical method. The number,mean profile areas and grey degree of TrkA-IR and ChAT-IR neurons were examined with image analyser. The data revealed thatTrkA-IR neurons were localized in the basal forebrain of rats. TrkA immunostaining was present at PDI, but ChAT was not.ChAT immunostaining was present at PD5. Most densely stained TrkA and ChAT neuronal bodies and fibers were present atPD20, the mean grey degrees of TrkA-IR and ChAT-IR neuronal profiles reached its peak. Both TrkA and ChAT neurons beganto cline at PD30 and maintained a relatively higher level in the adult. However, during aging both TrkA and ChAT-IR neuronsatrophy and became smaller than that in the adult. The number of TrkA-IR and ChAT-IR neurons were decreased by 41.38% and 51.61%; the mean profile areas decreased by 15.7% and 12.8%; and the mean grey degrees by 29.9% and 9.9%, respec-tively. The mean profile areas of TrkA-IR and ChAT-IR neurons from PD5 to aged rats were positively correlated. The resultsindicated that the expression of TrkA was earlier than ChAT. The expression of TrkA and ChAT followed a very similar tempo-ral pattern in the basal nucleus of Meynert from PD5 to aged rats, suggesting that TrkA might participate the regulation ofChAT-IR neuronal development, differentiation, maturation, and ageing. The down-regulation of TrkA and ChAT of aged ratsis associated with neuronal atrophy and loss and may contribute to the pronounced vulnerability of these neurons to degenerationin aging animals and Alzheimer's disease.

Objective To detect the expression of integrin ?5?1 in restenosed human vein grafts.Methods The expression of integrin ?5?1 and ?-smooth muscle actin(?-SMA) in 30 resected restenosed human vein grafts(from Kerfuff clinical hospital of Germany) was detected by confocal immunofluorescence with specific antibodies against ?5?1 and ?-SMA.Images were processed with Silicon Graphics Octane.Results In normal veins,integrin ?5?1 expression was very weak in media smooth muscle cells and in endothelium,and ?-SMA expression was present in media smooth muscle cells.In the restenosed vein grafts,integrin ?5?1 was strongly stained in the media smooth muscle cells and intimal endothelial cells,and moderately in the intimal smooth muscle cells,?-SMA was present in media smooth muscle cells and in the intimal smooth muscle cells.Conclusion Our research reveals that integrin ?5?1 is significantly upregulated in the media smooth muscle cells and intimal endothelial cells in the restenosed human vein grafts,suggesting the participation of integrin ?5?1 in the restenosis formation of human vein grafts.

DTC is the most common endocrine carcinoma and its routine treatment consists of total thyroidectomy and 131I thyroid remnant ablation.Currently,standard follow-up for DTC comprises Tg measurement and neck ultrasound as well as an additional radioiodine scan when indicated.As thyroid cells are assumed to be the only source of Tg in serum,circulating Tg serves as an excellent marker of persistent or recurrent disease in DTC follow-up.With the development of highly sensitive Tg assays,now it is possible to detect very low Tg concentrations which reflect minimal amounts of thyroid tissue without the need for TSH stimulation.This review is to introduce clinical implications of highly sensitive Tg assays.

0.05). Compared with group A, GMBF of group C, D, and E were reduced (P0.05). CONCLUSION: Hepatic portal interdicting can aggravate the gastric mucosa damage of the liver cirrhosis rat, and famotidine can protect against such gastric mucosa injury through improving the microcirculation of gastric mucosa.

Objective To investigate the postnatal developmental rule of TrkA and ChAT\|immunoreactive(ChAT\|ir) neurons and the relationship between TrkA and ChAT\|ir neurons in the horizontal limb of diagonal band(HDB) of rats. Methods Immunohistochemistry technique combined with image analyser were used. Results TrkA and ChAT\|ir neurons localized in the neurons of basal forebrain of rats. TrkA immunostaining was present at postnatal day 1(PD1), but ChAT immunostaining was present at PD5 Most densely stained TrkA and ChAT neuronal bodies and fibers were present at PD20, while the mean grey degrees of TrkA and ChAT\|ir neurons reached to the peak. Both TrkA and ChAT began to decline at PD30 and maintain a relatively higher level in the adult. However, during aging both TrkA and ChAT\|ir neurons atrophied and became smaller than that of adult. The number of TrkA and ChAT\|ir neurons decreased 39 8% and 33 3%;the mean areas 15 7% and 12 8%; the mean grey degree values were 29 9% and 9 9%, respectively. The mean areas, grey degrees and numbers of TrkA and ChAT\|ir neurons from PD5 to aged rats had positive correlation. Conclusion The results indicate that the expression of TrkA was earlier than ChAT. The expression of TrkA and ChAT followed a very similar temporal pattern in HDB from PD5 to aged rats, suggesting that TrkA may participate in the regulation of ChAT\|ir neuronal development, differentiation, maturation and aging. The down\|regulation of TrkA and ChAT of aged rats is associated with neuronal atrophy and loss and may contribute to the pronounced vulnerability of these neurons to degeneration in aging animals and Alzheimer disease.\;

Objective To investigate the effects of microRNA (miR)106a on the proliferation, apoptosis, migration and invasion of thyroid cancer cells in vitro.Methods 8505C and CGTH-W3 cell lines were used in the study.Overexpression and inhibition of miR106a were achieved by transfection of lentiviral vectors.The changes of gene expression were detected by quantitative real-time PCR (qRT-PCR) and Western blot analysis.Cell viability and apoptosis were evaluated by MTT assay and flow cytometry analysis, respectively.The caspase-9 activities in parental CGTH-W3 and 8505C cells and transfected sublines were measured.Wound healing and Transwell invasion assays were performed to determine cell migration and invasion.Two-sample t test and one-way analysis of variance were used to analyze the data.Results The level of miR106a in 8505C was up-regulated when compared to that in CGTH-W3 cells (t=10.28, P<0.01).Scrambled control and miR106a(-) were also successfully transfected into cells.Inhibition of miR106a suppressed cell viability, migration and invasion while promoted apoptosis and caspase-9 activity of 8505C cells, with significant differences among 8505C, 8505C-control, 8505C-miR106a(-) cells (F=147.0, 19.2, 100.3, 537.8, 804.3;all P<0.01).Overexpression of miR106a promoted cell viability, migration and invasion while inhibited apoptosis and caspase-9 activity of CGTH-W3 cells, with significant differences among CGTH-W3, CGTH-W3-control, CGTH-W3-miR106a(+) cells(F=9.2, 13.3, 622.8, 12.3, 19.6, all P<0.01).In addition, miR106a may up-regulate the expression of MEKK2 and p-ERK1/2.Conclusion Acting as an onco-miR, miR106a might promote the proliferation, migration and invasion of thyroid cancer cells and inhibit their apoptosis in vitro.

Objective:To explore whether the phospholipidoproteinaceous material deposit within the alveoli by a high-ifeld 3T MRI has signal characters and its application for diagnosing pulmonary alveolar proteinosis.Methods:A total of 11 patients with pulmonary alveolar proteinosis previously diagnosed by ifberoptic bronchoscope lung biopsy underwent 64-slice helical CT scans and 3T MRI scans, and the CT scans and the MRI scans were compared.
Results:hTe phospholipidoproteinaceous material deposit within the alveoli presented longer or equal T1 relaxation time and longer T2 relaxation time, without characters of fatty or deposits of protein-like substance signals and enhancement. The distribution, form, number and size of the lesions at T2WI were almost the same as those at CT, the lesions were irregular in morphology, and there was a clear boundary between the lesions and the adjacent normal lung tissues. Dynamic contrast-enhanced MRI showed thickened pulmonary arteriolae and venulae in the lesions with more obviously thickened pulmonary venulae, which were in conformity with the pulmonary artery and venule enhancement. CT scan in 1 out of the 11 cases showed lesions in both lungs mainly consisted of stripe-shaped and reticular structures, and no obvious sign of pulmonary alveolar proteinosis residue was found. MRI scan detected alveolar proteinosis that failed to be shown by CT scan.
Conclusion:3T MRI T2WI can easily detect the lesions of long T2 signals formed by the lipoproteinaceous material deposit within the alveoli. In the lesions, geographic appearance was presented, and the crazy paving pattern was dimly visualized. MRI can relfect the morphological characters of PAP like CT and it is slightly better compared with CT in such aspects as evaluating the theraputic effect of lung lavage. As supplement to CT, high-field 3T MRI can serve as an important examination for lung diseases.

Objective To assess metabolic alterations in the human basal ganglia area during maturation and aging by using 2D chemical shift imaging (2D CSI) of proton magnetic resonance spectroscopy (1H-MRS). Methods Seventy healthy subjects were examined by 2D CSI. 2D CSI imaging acquisition was performed in the bilateral caudate, lentiform and thalamus. 1H-MRS was processed to determine the metabolite ratios, including NAA/Cho, NAA/Cr, Cho/Cr. Seventy healthy subjects were divided into 3 groups:20 to 39 years of age group, 40 to 59 years of age group and 60 to 87 years of age group. The three groups of healthy participants were compared. Results There was a significant decrease with aging in the NAA/Cho ratio in the bilateral lcntiform, thalamus and left caudate, and a significant decrease with aging in NAA/Cr ratio in the bilateral thalamus,right lentiform and left caudate (P<0.05), whereas the Cho/Cr ratio was significantly increased in the bilateral lentiform with aging(P<0.05). Conclusions The results of 1H-MRS show significant changes in the level of metabolites during the process of aging. This technique may play an important role in clinical studies and applications for various conditions of metabolic disorders of the human brain.
