Objective To analyze the CT and MRI features of giant cell tumors of the skull. Methods 8 cases of giant cell tumors of the skull proven surgically and pathologically were analyzed retrospectively. CT and MRI(6 cases with post contrast CT and 5 cases with post contrast MRI scans)were performed in all cases. All tumors were excised surgically. Two weeks later,all patients undertook postoperative radiotherapy with the dosage of 4 500-6 000 cGy for five to six weeks. Results CT scan showed bone destruction and calcification. Most of the tumours were well defined with low signal intensities on T1 WI images, T2 WI images showed ununiformity signal. The low signal on T1 WI was still low signal intensity on T2 WI which suggested calcification. All patients had no distinctive change within the follow up period. Conclusion CT is able to clearly show bone destruction and calcification. MRI is superior to CT in demonstrating the outlines of the tumours. CT and MRI are effective methods in the diagnosis of the giant cell tumors. Surgery and postoperative radiotherapy are effective methods in the treatment of the giant cell tumors.

Objective To observe the effect of fluvastatin(Flu) on differentiation and induction of human promyelocytic leukemia HL-60 cells and provide the theoretical foundation for treatment of human promyelocytic leukemia.Methods The cultured HL-60 cells were treated with 20 ?mol?L-1 Flu,the morphological changes of the cell differentiation were examined.The NBT reduction capability was detected in HL-60 cells treated with Flu for 72 h.After HL-60 cells were treated with 20 ?mol?L-1 Flu for 5 d,they were stained with non-specific esterase and the percentage of differentiation cells was analyzed.Results The HL-60 cells treated with Flu showed smaller cell body,reducing proportion of nucleus to cytoplasm,the nucleus tortuosity,fold or sublobe.There were specific granules and vacuoles in cytoplasm,displaying that some cells had differentiated to relative mature cells.As compared with control group,the NBT reduction capability in HL-60 cells treated with Flu for 72 h was significantly higher than that in control cells(P

ABSTRACT:Objective To explore cardiac function and myocardial collagen type I in diet-induced insulin-resistant rats and the effect of telmisartan on cardiac diastolic function in diet-induced insulin-resistant rats. Methods We randomized 27 Wistar rats into control group (n = 9 ),high-fat group (n = 9 ),and telmisartan treatment group (n = 9 ).At the end of the study,left ventricular end diastolic pressure (LVEDP)and left ventricular systolic pressure (LVSP)of the rats and ± dp/dt were detected by carotid artery intubation.Masson cardiac staining was used to observe cardiac fibrosis,and collagen volume fraction (CVF)was measured.ELISA method was used to detect the concentration of plasma PICP and ICTP.Results Compared with the control group,in high-fat group LVEDP was significantly higher and -dP/dtmax decreased significantly (P < 0.01 );the plasma PICP level and the ratio of PICP/ICTP were significantly increased (P <0.01),cardiac collagen volume
fraction was significantly higher (P <0.01).After 22 weeks’telmisartan intervention,compared with the high-fat group,LVEDP and LVSP were significantly decreased (P < 0.01 ),but -dP/dtmax significantly increased (P <0.05).The level of the plasma PICP and PICP/ICTP were significantly decreased (P < 0.05 );left ventricular myocardial tissue collagen volume fraction content was decreased (P <0.01).The correlation analysis showed that cardiac collagen volume fraction in insulin-resistant group was positively correlated with insulin resistance index but negatively correlated with -dp/dtmax (P < 0.01 ).Conclusion Insulin resistance promoted the synthesis of myocardial type I collagen,leading to increased myocardial collagen deposition and decreased cardiac diastolic function.Telmisartan may improve diastolic function partly by improving insulin resistance and reducing the deposition of myocardial collagen type I.

Objective To compare the clinical value of 18F-FDG PET imaging and 99Tcm-MDP whole body bone imaging in detection of bone metastases. Methods 43 patients were undergone 18F-FDG PET and 99Tcm-MDP imaging within 2 weeks. 28 of them were with confirmed bone metastases by other examinations or follow-up and the remaining 15 were confirmed without bone metastases. The results of the 2 different modalities were analyzed. Results Among 28 patients with confirmed bone metastases, PET and MDP accurately diagnosed 26 and 27, respectively. The sensitivity of them were 92.9 %(26/28), 96.4 %(27/28), Among the remaining 19 cases without bone metastases, PET and MDP correctly gave 14 and 8 negative results, respectively. The specificity of them were 93.3 %(14/15), 53.3 %(8/15), and accuracy of them were 93.0 %(40/43), 81.4 %(35/43). The differences between specificities and accuracies of the two methods were significant, while no significant difference between the sensitivities of the two methods. Conclusion For the detection of bone metastases in patients with malignant tumors, 18F-FDG PET showed a similar sensitivity but better specificity and accuracy compared with 99Tcm-MDP bone scan. For patients with suspected bone metastases, negative finding or single hot spot in 99Tcm-MDP imaging, 18F-FDG PET imaging was recommend as a further and complementary assessment of bone metastases.

To assess the impact of the operational simulation training system on the cultivation of ophthalmic students.
●METHODS: Four hundred and eighty ophthalmic students in China Medical University from 2009 to 2011 were chosen as objects and divided into two groups at random. The students in the experimental group used operation simulation training system combined with traditional teaching methods, while the students in the control group only used traditional teaching methods. We examined the operation skills and the confidence of all the students half a year later.
●RESULTS: The improvement of the operation skills during the suture technique examination, and the confidence for operation technology were significantly different in two groups. The basic skills of the students in the examination groups improved apparently during the operational simulation training and they were full of confidence to their operational technique.
●CONCLUSlON: The operational simulation training is useful for promoting the clinical ability for ophthalmic students and should be widely popularized.

Objective To investigate the effects of miR-19 on the migration ability of lung adenocarcinoma cell line A549. Methods The expressions of miR-19 in lung epithelial cell line BEAS-2B and lung adenocarcinoma cell line A549-Luc were detected by qRT-PCR.The A549-Luc cell line which over-expressed miR-19 was established. The expression levels of miR-19 in A549/RFP+/H2B and A549/RFP+/m19 were identified by qRT-PCR. The morphology of A549/RFP+/m19 was observed,and the migration ability of A549/RFP+/m19 was detected by transwell migration assay. Results The expression levels of miR-19 differed significantly between BEAS-2B cells and A549-Luc cells (t = -20.954, P < 0.001). The lung adenocarcinoma cell line A549/RFP+/m19 which over-expressed miR-19 was successfully established. Changes in A549/RFP+/m19 cell morphology were found. As compared with A549/RFP+/H2B cells, A549/RFP+/m19 had an increased migration ability (P <0.01). Conclusions miR-19 enhances the migration ability of lung adenocarcinoma A549-Luc cells.

Objective To discuss MRI characteristics of dysplastic gangliocytoma of the cerebellum.Methods MRI manifesta-tions of 13 cases with dysplastic gangliocytoma of the cerebellum verified by operation and pathology were analyzed retrospectively. Results All of 13 cases were located in the cerebellar hemisphere and vermis.The lesions presented striated pattern of iso-intensity signal and hypo-intensity signal on T1-weighted images.The sign of tiger stripes was the feature in dysplastic gangliocytoma on T2-weighted and FLAIR images.All of the tumors showed slightly striated enhancement after intravenous administration of contrast agent.The mass effects of dysplastic gangliocytoma of the cerebellum along with the forth ventricle and brain stem oppressed were seen in all cases.NAA was mildly reduced on magnetic resonance spectroscopy (MRS)in 7 cases of dysplastic gangliocytoma of the cerebellum.Conclusion There are distinctive manifestations in MRI images for dysplastic gangliocytoma of the cerebellum,which has crucial diagnostic value before operation.
