Objective To summarize the experience on the diagnosis and therapy of intravenous leiomyomatosis(IVL)of the inferior vena cava.Methods Eight IVL patients were treated in our hospital from March 1998 to April 2007. Results The diagnosis of IVL of the inferior vena cava was established histologically by biopsy during inferior vena eavagram before operation in 4 patients.Seven patients received open surgery.Except one patient dying of massive hemorrhage during operation and one IVL recurrence during follow-up,postoperative course was uneventful and an average follow-up of 29 months found no recurrence in the other five patients. Conclusion The final diagnosis of IVL of the inferior vena cava depends on venogram and biopsy,and it is an estrogen dependent tumor originating from uterus leiomyoma.Total surgical extirpation of the tumor is the only effective treatment for IVL.

We present two cases of clear cell meningioma (CCM) in the intracranial and intraspinal region with anaplastic features. On histological examination, both the tumors exhibited unusual anaplastic appearances with nuclear pleomorphism, a high mitotic activity and necrosis, which were different from classical CCMs. The tumor cells were immunoreactive to epithelial membrane antigen (EMA) and vimentin with a high MIB-1 index of 40%. Total excision of the tumors was performed in both cases. The male patient was found to have local recurrence and lateral ventricle metastasis 3 months after the total excision. We reviewed the clinicopathological features, disagnosis and prognosis of the disease. We recommend that postoperative adjuvant radiotherapy or chemotherapy be performed after total tumor excision, and MRI scan every 3-6 months is mandatory during the initial follow-up period.

Objective:To investigate the effect of lncRNA HOTTIP on the radiosensitivity of four non-small cell lung cancer cell lines cultured in vitro by regulating the expression of miR-663a. Methods:Four non-small cell lung cancer cell lines (H838, H157, A549, and H1299) were irradiated with different radiation intensities (0, 2, 4, 6, and 8 Gy). Cell survival was detected by colony formation assay. The expression levels of HOTTIP and miR-663a were detected by qRT-PCR. A549 and H1299 cells were selected for the subsequent experiment. After silencing HOTTIP and/or over-expressing miR-663a, cell survival was detected by colony formation assay. Cell apoptosis was detected by flow cytometry. The expression levels of Cleaved caspase-3, Cleaved PARP andγ-H 2AX were quantitatively measured by Western blot. The targeting relationship between HOTTIP and miR-663a was vefiried by dual luciferase reporter assay and qRT-PCR. Results:The expression of HOTTIP was up-regulated, whereas that of miR-663a was down-regulated in the radiation-resistant H157, A549 and H1299 cells. Silencing HOTTIP or over-expressing miR-663a inhibited the survival of A549 and H1299 cells (radiosensitization ratios were 1.562 and 1.507, respectively), promoted the expression of Cleaved caspase-3, Cleaved PARP and γ-H 2AX, and accelerated cell apoptosis induced by radiation exposure. miR-663a was a target gene of HOTTIP, and HOTTIP negatively regulated the expression of miR-663a. The inhibition of miR-663a reversed the effect of silencing HOTTIP on the radiosensitivity of non-small cell lung cancer cells. Conclusion:Silencing HOTTIP can suppress the survival of non-small cell lung cancer cells and promotes cell apoptosis by up-regulating the expression of miR-663a, thereby enhancing the radiosensitivity of non-small cell lung cancer cell lines.
