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.

Objective To study the effect of the modality of subtotal splenectomy with retroperitoneal splenic transposition combined with devascularization on portal hypertensive gastropahy(PHG). Methods Subtotal splenectomy with retroperitoneal splenic transposition combined with devascularization was performed in 48 cirrhotic patients with portal hypertension. Forty seven patients were followed up for 2 years to 13 years (average 91 months). PHG were observed by gastroscopy.Results At 2 months postoperation ,PHG was significantly aggravated compared with that of preoperation (P

Objective To probe into the clinical value of the whole pelvis internal organs joint excision in locally advanced cervical carcinoma. Methods Four cases of local cervical carcinoma patients who have been implemented the peculiar operation from April 1997 to April 2001 were analyzed. Results The operation progressed well and the time of surviving was 4-41 months, 16.3 months in life cycle on average. 4 patients died of intestinal obstruction, vagina-small intestine atrophy and the pain of pelvis which resulted in a hunger strike and lung metastasis. Conclusion Implement the operation to those patients whose rectum and bladder were invaded simultaneously can lengthen a patient's life cycle and improve the quality of surviving. To grasp the operation target, standardize the step and improve the treatment method before and after operation were necessary.

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.

Adrenal Castleman's disease is rare. One case of left adrenal Castleman's disease, who underwent retroperitoneal laparoscopic left adrenal gland and tumor resection. The postoperative pathological diagnosis was adrenal Castleman's disease (transparent vascular type), and no tumor recurrence was found after 2 years of follow-up.

Objective:To investigate the influence of nonylphenol (NP) on cytoactive and the expression of G protein-coupled estrogen receptor 30 (GPR30) in human colon cancer SW480 cells.Methods:The experimental study was conducted. The human colon cancer SW480 cells were cultured in vitro. The influence of NP on proliferation, cell cycle, apoptosis and the expression of GPR30 in human colon cancer SW480 cells were analyzed by cell proliferation, cell cycle detection, cell apoptosis and gene expression and protein expression experiments. Cell grouping: SW480 cells cultured with medium were set as the control group, cultured with medium+1×10 ?8 mol/L estradiol were set as the estradiol group, cultured with medium+1×10 ?8 mol/L NP were set as the NP group, cultured with medium+1×10 ?8 mol/L NP+1×10 ?7 mol/L GPR30 specific antagonist G15 were set as the NP+G15 group, respectively. Observation indicators: (1) proliferation index of human colon cancer SW480 cells in the 4 groups; (2) cycle proportion of human colon cancer SW480 cells in the 4 groups; (3) apoptosis index of human colon cancer SW480 cells in the 4 groups; (4) GPR30 messenger RNA(mRNA) expression of human colon cancer SW480 cells in the 4 groups; (5) GPR30 protein expression of human colon cancer SW480 cells in the 4 groups. Measurement data with normal distribution were represented as Mean± SD and one way ANOVA was used for comparison between groups. The least significant difference method was used to test the pairwise comparison. Results:(1) Proliferation index of human colon cancer SW480 cells in the 4 groups. Results of the cell proliferation experiments showed that the proliferation indexes of human colon cancer SW480 cells in the control group, the estradiol group, the NP group and the NP+G15 group were 100.00±0.00, 89.19±4.86, 148.96±6.04 and 120.40±3.39, respectively, showing a significant difference among the 4 groups ( F=21.45, P<0.05). There was a significant difference between the control group and the NP group ( P<0.05), and there was no significant difference between the control group and the estradiol group, between the control group and the NP+G15 group ( P>0.05). (2) Cycle proportion of human colon cancer SW480 cells in the 4 groups. Results of the cell cycle detection experiments showed that the proportions of human colon cancer SW480 cells in the S phase of the cell cycles in the control group, the estradiol group, the NP group and the NP+G15 group were 39.96%±2.02%, 36.67%±0.62%, 43.85%±1.02% and 38.29%±1.42%, respectively, showing a significant difference among the 4 groups ( F=10.08, P<0.05).
