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 study the express of matrix metalloproteinase(MMP)-2 and tissue inhibitor of metalloproteinase(TIMP)-2 protein in human endometrial carcinoma. Methods The Immunohistochemistry was used to measure the MMP-2, TIMP-2 in endometrial carcinoma tissue of 40 patients, the atypical hyperplasia of 12 samples and the normal endometrium of 12 samples. Results The positive express of MMP-2 and TIMP-2 in the normal endometrium , atypical hyperplasia and endometrial carcinoma was increased gradually. In endometrial carcinoma, with progression of clinical stage and decrease of histological grade as well as deepening of cancer invasion, the ratio of MMP-2/TIMP-2 was increased. Conclusions The expression of MMP-2 and TIMP-2 were connected with endometrial carcinoma. The imbalance of MMP-2/TIMP-2 in the endometrial cancer might be one of the pathogenesis and development.

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 investigate pathogenic factors,clinical characteristics,pathological changes in 6 patients with localized or disseminated intestinal neuronal dysplasia(IND).Methods The clinical retrospective study was performed in 6 cases with localized and disseminated IND.Results In 6 patients,constipation and partial intestinal obstruction were the major symptoms.Preoperatively,dia-gnoses were revaluated as intestinal stenosis in 2 cases,long sigmoid in 2 cases and long-segment aganglionosis and total gastrointestinal IND in the rest 2 cases,respectively.Exploratory laparotomy was performed on all these patients.Pathological study suggested that 4 of them were localized IND,on whom enterectomy and intestinal anastomosis were performed successfully.However,2 cases of disseminated IND died postoperatively.Conclusions Disseminated IND may be caused by congenital factors,while localized IND by the acquired factors which including intestinal obstruction,local ischemia or inflammation.The surgical interventions are effective for localized IND,and intestine transplantation might be prospective treatment for disseminated IND.

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.

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
