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 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.

Objective To explore the technique and the clinical value of Neuroform stents in combination with Guglielmi detachable coil(GDC) to treat wide-necked basilar artery aneurysms.Methods 30 cases with wide-necked basilar artery aneurysms were treated with Neuroform stent combined with GDC.Of 30 wide-necked basilar artery aneurysms,the location of lesions was at basilar tip in 16,basilar trunk in 9 and the beginning of the basilar in 5.Results In 30 cases,total occlusion was achieved in 25 and partial occlusion in 5 patients.The thrombosis within stent occurred in 2 patinets,and remainder of patients recovered well.There were no thromboembolic events in 20 cases followed up for 3~6 months.Twenty-two patients were angiographically followed up for 3 months after the procedure,among them,the aneurysms visualized and the arteriae burdened aneurysms were passed free in densely packed and 3 aneurysms with neck remnant.Conclusion The Neuroform stent is a easy and safe intracranial stent for embo1ization of wide-necked intracranial aneurysms,especially suitable for wide-necked basilar artery aneurysms with severely tortuous intracranial artery.

Aim To investigate and evaluate the effect of ligustrazine on the expression of scavenger receptor type AI, the human ?-interferon activation site (GAS) elements regulatory systems of SR-AI expression wasfirst established in the Xenopus oocytes. Methods A plasmid, in which the human SR-AI gene was constructed downstream from the GAS elements, was microinjected into the nucleus of Xenopus oocytes. The oocytes then were cultured in the smooth muscle cell conditioned medium (SCM), In which the cell were cultured with the treatment of oxLDL for 2 days. In the other groups, the oocytes were treated with SCM containing the nature medicines ligustrazine, and the positive control drug ?-interferon respectively. Results The results demonstrated that SCM could upregulate the expression of SR-AI in this system, this action was suppressed by ligustrazine and ?-interferon. Conclusion Similar to the action of ?-interferon, ligustrazine can prevent the over-expression of SR-A induced by oxLDL, via their effect on the GAS elements regulatory pathway.

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.
