Objective To evaluate the effect of tranilast on chronic cyclosporin A(CsA)nephrotoxicity rats and the possible mechanisms of protective effect of it.Methods Rats were on low salt diet and CsA was administered by gastric gavage at a dose of 20 mg/(kg?d)for 28 days,and tranilast was gave to these rats in a dose of 400 mg/(kg?d).The renal function and renal morphology were observed at1,2 and 4 weeks after administration of tranilast.Results CsA induced the corruption of normal condition and weight lost were markedly delayed after administration of tranilast.On histopathology tranilast attenuated tubular cells vacuolations as well as interstitial damage including interstitial ED1+ macrophages infiltration and focal interstitial fibrosis.Meanwhile,tranilast down-regulated the protein of OPN in kidney.Conclusion Tranilast can attenuate the structural changes of kidney in chronic CsA nephrotoxicity rats.Decreased CsA-related ED1+ macrophages,OPN up-regulation expression in the kidney may be related to mechanisms of protective effect of tranilast in the treatment of CsA induced chronic nephrotoxicity.

BACKGROUND: Studies show that proper exercise has the effect of anti-aging, increasing bone mass accumulation and reducing bone mass loss. OBJECTIVE: To investigate the effect of aerobic exercises on osseous composition In aging rats. DESIGN, TIME AND SETTING: A randomized control animal experiment was completed in the Animal Experiment Laboratory of Xi'an Sports Institute from April to June in 2007. MATERIALS: A total of 64 clean male SD rats weaned for 2 months were randomly divided into a normal control group, a non-modeling exercise group, an aging model group and a modeling exercise group, with 16 ones in each group. Every 8 rats of each group were sacrificed at the 6th and 9th week respectively.exercise for 6 and 9 weeks. MAIN OUTCOME MEASURES: At the end of week 6 and 9, rats in each group were detected regarding to the following measures: serum alkaline phosphatase, bone gla protein, serum propeptide of type] procollagen, serum total calcium, serum inorganic phosphorus, serum magnesium, urinary calcium, urinary inorganic phosphorus, urinary magnesium, urinary hydroxylysine glycoside. Bone trabecula changes in femoral bone tissue were observed with light microscope. RESULTS: Compared with the normal control group, the aging model group got a decrease at the following indexes at both week 6 and week 9, namely, serum alkaline phosphatase, serum propeptide of type Ⅰ procellagen, serum total calcium, serum magnesium, urinary calcium, urinary inorganic phosphorus, urinary hydroxyproline. While in the non-modeling exercise group and the modeling exercise group, these above-mentioned indexes increased. Compared with the normal control group, the aging model group got an increase at the following indexes at both week 6 and week 9, namely, serum osteocalcin, inorganic phosphorus, adnary magnesium, urinary hydroxylysine glycoside. While in the non-modeling exercise group and the modeling exercise group, these above-mentioned indexes decreased. In Addition, exercise of 9 weeks led to a better recovery result than that of 6 weeks. The detection under light microscope showed an obvious few bone trabeculas in the aging model group and an increase of bone trabeculas per unit volume in the non-modeling exercise group and the modeling exercise group. CONCLUSION: Aerobic exercise has a great effect on the morphosis of femoral bone osseous composition in aging rats, and it can delay osteoporosis.

Objective To explore the value of MRI dynamic contrast-enhanced in differentiating adrenal adenomas from nonadenomas with washout rate of enhancement and the increased SI ratio. Methods Thirty-six patients with 41 adrenal masses enrolled into this study. All these masses underwent conventional T 1WI and T 2WI sequence first, and then FMPSPGR sequence through the center of each mass. Precontrast and dynamic contrast-enhanced FMPSPGR scans were preformed after administration of contrast material of Gd-DTPA intravenously. The signal intensity(SI) of masses was measured on the screen by electronic cursor. The washout rate of enhancement and increased SI ratio were compared between adenomas and nonadenomas. The differentiating adrenal adenomas from nonadenomas were carried out based on combination of the washout rate and the increased SI ratio, meanwhile, the sensitivity and specificity of the diagnosis of adenomas were evaluated well.Results The sensitivity and specificity of the diagnosis of adenomas were 74% and 73%,and accuracy was 73% when the washout ratio was used as a indicator at 5 min. The sensitivity and specificity of the diagnosis of adenomas would be improved markedly when the combination of the washout ratio and the increased SI ratio was used as a indicator.The sensitivity and specificity of the diagnosis of adenomas were 95%, 91% respectively,and accuracy was 93%. Conclusion Using MRI dynamic contrast-enhanced based on combination of washout rate of enhancement and the increased SI ratio,the diagnosis and differentiating diagnosis of adrenal adenoma and nonadenoma can be improved.

Objective To determine the expression of cancer stem cell markers, CD133, CD44 and OCT-4, in small cell lung cancer cell line NCI-H82 and confirm the specific markers. Methods NCI-H82 cells were cultured, and the expressions of markers (CD133, CD44 and OCT-4) were detected by immunofluorescence staining. The immunohistochemistry was performed to detect the expressions of CD133, CD44 and OCT-4 in 79 tissues with small cell lung cancer. Results In NCI-H82 cells, the florescence was positive in CD133 and CD44 and negative in OCT-4. In the tissues, the expression of CD133 and CD 44 was related with tumor size, lymph node metastasis and clinical stage (P< 0.05), while OCT-4 was negative expression. Conclusion CD133 and CD44 might be the cancer stem cell markers of small cell lung cancer, which maybe have clinical significance on diagnosis and treatment.

This study aims to detect early changes of kidney in patients with primary hypertension by 3.0 T functional magnetic resonance imaging (fMRI). 26 patients with primary hypertension (hypertension group) and 33 healthy volunteers (control group) underwent conventional and functional magnetic resonance scans, which included blood oxygen level-dependent (BOLD) MRI, diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI). We measured renal cortical thickness (CT), parenchymal thickness (PT), and functional values of renal cortex and medulla including R2* value, apparent diffusion coefficient (ADC) value and fractional anisotropy (FA) value in each group, and then calculated the cortical/parenchymal thickness ratio (CPR). Compared with those in the control group, CT and CPR in hypertension group were larger (P < 0.01), cortical and medullar R2* values increased (P < 0.01) whereas medullar FA values decreased (P < 0.05). It could be well concluded that noninvasive 3.0 T functional MRI would have important clinical significance in identifying early abnormalities of kidney in hypertension patients.
