Objective To evaluate the role of multidetector CT(MDCT) and high magnetic field MRI in diagnosis of small cystic-solid renal mass. Methods Fifty-two cases with small renal cystic-solid mass(≤3 cm) were consecutively collected,including small cystic-solid renal cell carcinoma(n=25),carcinoid(n=1),complex cysts(n=16),small angiomyolipoma(n=7) and benign cystic nephroma(n=3).All were examined by both 1.5T MRI and multidetector CT at intervals between 3 days and 2 months. Results All cases were proved by pathology.Multi-planar reconstruction techniques were useful for MDCT in differentiating small cystic-solid renal mass,with the sensitivity of 98.1%,which was as high as MRI.However,the accuracy for MDCT was 71.2%,significantly lower than that of MRI(90.4%)(P=0.001).MRI helped to identify the components and structure of renal masses,and behaved better in the detection of pseudo-capsule of renal cell carcinoma(57.7%).Conclusion High magnetic field MRI may play an important role in the diagnosis of small renal cystic-solid masses,and it may be feasible as a noninvasive examination when CT can not make the ultimate determination.

OBJECTIVETo explore the effects of nano-hydroxyapatite/polyamide 66 (n-HA/PA66) cage on recovering and maintaining lumbar curvature, lumbar heights and fusion rate when used in the transforaminal lumbar interbody fusion.
METHODSFrom February to July 2012, 50 patients with degenerative lumbar disease(lumbar disc herniation in 32 cases and lumbar spondylolisthesis in 18 cases) were treated with transforaminal lumbar interbody fusion using the n-HA/PA66 cage, and their preoperative and postoperative clinical outcomes were analyzed. The patients were followed up for 2, 4, 6 and 8 months after operation, during which the CR and CT film of lumbar vertebra were checked to get relative height of vertebral space, Taillard index,index of lumbar spinal curvature,angle of segmental and full lumbar lordosis. The data were analyzed respectively with pair t-test, analysis of variance or LSD-t-test.
RESULTSAll the patients were followed up, and the duraion ranged from 8 to 13 months, with a mean of 11.32 months. There were significant differences in relative height of vertebral space, Taillard index, index of lumbar spinal curvature, angle of segmental and full lumbar lordosis after surgery, but there were no significant differences in different periods after operation. The fusion time of lumbar ranged from 4 to 8 months.
CONCLUSIONThe n-HA/PA66 cage can recover and maintain lumbar normal stability with higher rate of fusion and less complications.

Objective To observe the effects of Niupo Zhibao pellet, a compound traditional Chinese herbal medicine,on helper T cell(Th cell)expression in rats with endotoxin-induced rapid pulmonary fibrosis (RPF). Methods Two hundred and twenty-four Wistar rats were randomly divided into four groups:normal control,model,dexamethasone(DXM)and Niupo Zhibao pellet(NW)groups(each n=56). By using endotoxin three-hit regimen,the RPF model was established. Three days before and 7 days after the establishment of models in NW group,they were administered with the pellet by intragastric feeding,50 mg/100 g of distilled water twice a day,a total of 10 days medication. Rats in DXM group received DXM intraperitoneal injection,3.0 mg/kg once a day for consecutive 7 days. Rats in normal control group were administered with the same volume of distilled water by intragastric administration. On 1,3,7,9,14,21,28 days after the administration,blood and bronchoalveolar lavage fluid(BALF)specimens were collected. The contents of γ-interferon(IFN-γ)and interleukin-4(IL-4) in the serum and BALF were investigated by enzyme-linked immunosorbent assays(ELISA). The lung tissue was stained by hematoxylin-eosin(HE)and Van Gieson respectively. Morphological changes in lung tissue were observed under light microscope. Results HE staining showed that the pulmonary interstitial tissues of rats in model group were thickened,there was a large amount of inflammatory exudates,and micro thrombi were seem in alveolar space. The pulmonary interstitial tissues in rats of DXM group were thickened too,but the inflammatory exudate in alveolar space was much less. Compared to rats in DXM group,the rats in NW group had slightly more inflammatory exudate and their pulmonary interstitial tissues were basically normal. Van Gieson staining showed that the expression of collagen fiber in model group was obvious,that of DXM group less than the former one but not significant,while that in the NW group was reduced markedly. ELISA assays demonstrated that the levels of IFN-γin BALF and serum in model group were increased significantly,those in DXM group were lowered to the minimum on the 7th day,raised to the levels before treatment on the 14th day,and gradually declined on the 21st day. In the NW group,the IFN-γwas consistently at a high level,and then gradually declined at a slow rate. After 7 days of drug administration,the IFN-γ levels in BALF and serum at various time points in NW group were obviously higher than those in model and DXM groups〔BALF(ng/L):140.47±4.22 vs. 149.23±8.35,90.67±6.65;serum(ng/L):140.47±4.15 vs. 100.43±11.05,99.35±7.85,P<0.05 or P<0.01〕. The levels of IL-4 in BALF and serum in each group increased significantly,reached to their maximum on the 7th day,and then gradually decreased. After the drug administration for 28 days,those levels in NW group were obviously lower than those in model and DXM group〔BALF(ng/L):6.60±1.05 vs. 7.20±1.25,8.55±1.05,serum(ng/L):6.75±1.05 vs. 7.21±1.25,8.25±1.15,P<0.05 or P<0.01〕. Conclusion Niupo Zhibao pellet can suppress inflammation,ameliorate injury of lungs and inhibit lung fibrosis by promoting IFN-γsecretion,restraining IL-4 secretion and adjusting the imbalance of Th cells.
