Objective To evaluate the clinical application of contrast-enhanced digital subtraction MRI in vertebral metastases.Methods 50 patients with vertebral metastases were scanned by contrast-enhanced T_1WI with an injection of Gd-DTPA(0.1 mmol/kg).Digital subtraction were performed between post-contrast-enhanced images and pre-contrast-enhanced images.Vertebral metastases were evaluated by means of a contrast to noise ratio(CNR) and signal to noise ratio(SNR),and boundaries were compared between subtraction MRI images and conventional contrast T_1WI MR images.Results Contrast-enhanced digital subtraction MRI images were better than conventional contrast T_1WI MR images in showing the lesions. All lesions had a higher CNR and SNR on subtraction MR imaging than that on conventional contrast T_1WI MR images.CNR was 155.05 ? 24.73(mean ? standard error) for subtraction MR imaging and11.11?14.26 for conventional contrast T_1WI MR images,(t=35.65,P

Objective To investigate the significance of measuring carotid arterial intima-media thickness(IMT) and diabetic retinopathy(DR).Methods 76 diabetic patients were divided into three groups:no diabetic retinopathy(NDR),nonpmliferative diabetic retinopathy(NPDR),and proliferative diabetic retinopathy(PDR).20 helath people were chosen as control All subjects were examined by ColorDoppler imaging on the carotid arterial intima-media thickness.Results The mean IMT was significantly higher in T_2DM patients than in normal control group(P

Objective To evaluate the value of double stapling technique with curved cutter stapler in colorectal anastomosis,especially in low colorectal anastomosis. Methods The clinical data of 168 cases of rectal carcinomas treated with double stapling technique with curved cutter stapler were retrospectively reviewed.The intraoperative condition,postoperative complications and findings during follow up were analysed. Results During the operations,the processes of closure and anastomosis of all the patients were satisfactory,and no operative death occurred.After the operations,4 cases(2.4%) had anastomotic leakage,3 cases(1.8%) had anastomotic bleeding,and 2 cases(1.2%) had rectovaginal fistula.All the complications were cured.There was no anastomotic stricture. Conclusion Double stapling technique with curved cutter stapler may help to accomplish low colorectal anastomosis which is a difficult task for handed suture.

ObjectiveTo investigate whether aldosterone infusion induces glomerular or podocyte injury in rats and to evaluate the effects of eplerenoen (EPL), andodipine (CCB) and telmisartan (ARB) on aldosterone- induced injury. MethodsThirty male Sprague-Dawley rats were divided into 5 groups: control, subcutaneous infusion of aldosterone (1.5 μg/h, ALD group) and aldosterone infusion plus eplerenone (100 mg·kg-1·d-1, EPL group), amlodipine(10 nag·kg-1·d-1 CCB group), telmisartan (3 mg·kg-1·d-1, ARB group), respectively. Systolic blood pressure(SBP) and urinary albumin excretion ratio(UAER) were measured at day 0, 7, 14, 21, 28. Blood samples were harvested to detect plasma angiotensin Ⅱ, plasma aldosterone, serum sodium, serum potassium and serum creatinine at day 28. Glomerular damge was quantified by morphological glomerular injury score (GIS). Immunohistochemistry and RT-PCR were performed to evaluate podocyte lesion, and apoptosis ratio of pedocyte (ARP) in a glomerular cross section was analyzed by TUNEL. ResultsALD infusion progressively increased SBP and UAER compared with CTL (P<0.01). SBP was significantly reduced in EPL, CCB or ARB-treated animals, meanwhile, UAER was decreased in EPL and ARB group, but not in CCB group. The ALD-infused rats exibited hypernatremia and hypopotassaemia, which were blocked by EPL adminstration but not by CCB or ARB treatment. ARB group had a significant increase in plasma angiotensin Ⅱ compared with ALD, CCB and EPL groups(P<0.01). The ALD-infused animals developed hyperaldosteronemia compared with CTL, but with no difference of plasma aldosterone among ALD, EPL, CCB and ARB-treated rats. Treatment with EPL prevented an increase of GIS and ARP compared with CCB and ARB (P<0.05, P<0.01). Protein and mRNA expression of nephfin was up-regulated in ALD group (P< 0.01), but was significantly prevented by EPL treatment(P<0.01), whereas CCB and ARB therapy had no such effect. Conclusion ALD infusion significantly induces glomerular and pedocyte injury which is blocked by EPL but not by CCB or ARB independently on systemic hemodynamics.

This study aimed to design a pair of primers for amplifying internal transcribed spacer 2 region which was used to identify Gastrodia elata through optimizing of DNA extraction and PCR amplification process. Two sequences are used for research object by amplification of universal primers. Design three pairs of specific primers by Primer Premier 5.0 and select the highest specificity through the study of 22 samples. The results showed that identification efficiency of the primer named TM2F-2R is as high as 90.9% when Annealing Temperature is equal to 54 degrees Celsius. Therefore, TM2F-2R can be used as primers ITS2 sequences of G. elata, this article provides a set of accu-rate and stable identification methods for G. elata in the molecular identification.
