Objective To investigate the influence of the radical resection and the optic canal unroofing on the postoperative vision in the patients with tuberculm region meningeal tumors.Matheods A retrospective analysis was made in 44 patients with tuberculm region meningeal tumors,from January 2010 to October 2012.The clinical data including the Simpson grades,adhesion between tumor and the surrounding structures,optic canal decompression,and postoperative vision were studied,and followed-up.Results In all 44 cases,there were 31 patients with Simpson grade Ⅰ resection,their postoperative vision of 17 patients were improved,eleven unchanged,and 3 worse.Out of them,tumors showed more adhesive in 9 cases,unroofed the optic canal in 17 cases.There were 13 cases in the other group including 8 cases with Simpson grade Ⅱ and 5 cases with Simpson grade Ⅲ,their postoperative vision of 8 patients were improved,four unchanged,and 1 worse.Out of them,tumors showed more adhesive to the surroundings in 10 cases,unroofed the optic canal in 3 cases.There were no different postoperative vision among the Simpson grades by the Chi-Square test (P ＞ 0.05).The less adhesive of the meningeal tumors,the better resection grade would be (P ＜ 0.05).And unroofed the optic canal group showed better postoperative vision than the not unroofed ones (P ＜ 0.05).Conclusion In the tuberculum region meningeal tumors,the Simpson resection grade was related to adhesion between the meningeal tumors and the surroundings,not to postoperative vision.The optic canal decompression can improve their visual outcome in some cases.

Objective:To assess the survival-predictive value of TNM and Lugano staging systems in patients with primary gastro-intestinal lymphoma (PGL). Methods:A total of 73 patients with PGL were recruited from February 2001 to August 2013. All patients were diagnosed according to the TNM and Lugano staging systems. Five-year survival rate was used as the major clinical outcome. Sur-vival curves were plotted using the Kaplan–Meier method and analyzed with the log-rank test. The prognostic value of different vari-ables for clinical outcomes was assessed using the Cox multiple regression model. Results:The median follow-up time of surviving pa-tients was 42.4 months (range:1.3-158.6 months). The estimated 5-year overall survival rate was 77.82%. When diagnosed with the TNM system, the 5-year survival rates in stagesⅠ,Ⅱ,Ⅲ, andⅣwere 100%, 90.0%, 67.4%, and 22.2%, respectively (χ2=17.7956, P=0.0005). When staged by the Lugano system, the 5-year survival rates in stagesⅠ,Ⅱ,ⅡE , andⅣwere 100%, 100%, 70.7%, and 46.2%, respectively (χ2=15.6776, P=0.0013). Cox analysis showed that the invasion depth (T) (P=0.0181) and metastasis (M) (P=0.0031) were covariates that were prognostically significant for the overall survival. Conclusion:The TNM staging system is more ac-curate than the Lugano system in predicting the 5-year survival rate of patients with PGL.

Objective To explore the feasibility of artificial silastic framework(SF)in repair of large area of tracheal wall defects.Methods Twenty healthy adult dogs with tracheal defects for 2.5 cm?6.0 cm-3.0 cm?6.0cm were randomly and equally divided into experimental group(repaired with SF combined with sternohyoid fasciae)and control group(repaired with T-silastie tubule combined with sternohyoid fascial flap).After the operation,the animals were sacrificed at the 4th,8th,16th,24th, and 48th weeks respectively for harvesting the tracheae that were used for tracbeoscopically observing in- flammatory reaction of the repaired defect area and light microscopically observing epithelium healing on the repaired defect area.Results In the experiment group,the repaired trachea was smooth,without proliferation of granulation;and at the 8th week,the repaired defect area was covered with epithelial cells,with good functional recovery of respiration,phonation and deglutition.In the control group,there was obvious proliferation of granulation on the tracheal surface near anterior and posterior ends of T-silas tic tubule.The animals were under asphyxia to die with extraction of T-silastic tubule.Conclusions SF has excellent tracheal skeletal function.In the meantime,SF combined with sternohyoid fasciae is a simple but effective method for repair of large area of tracheal wall defects.

AIM:To characterize the effect of estradiol on proliferation,differentiation and extracellular matrix(ECM) accumulation in stromal cells through regulation of BPH-1 paracrine.METHODS:BPH-1 cells were stimulated with different concentrations of estradiol.Conditioned media(CM) were harvested and their effects on stromal cell cultures were tested.Cell proliferation was determined by MTT assay.mRNA of smoothelin,fibronectin,collagen Ⅳ and transforming growth factor ?1(TGF-?1) were analyzed by real-time RT-PCR.Western blotting was used to determine smooth muscle myosin heavy chain(SMMHC).ELISA and radioimmunoassay were respectively used to measure fibronectin,TGF-?1 and collagen Ⅳ protein expressions.RESULTS:Estrodiol stimulated the expression and secretion of TGF-?1 in BPH-1 cells.The proliferation of stromal cells increased when they were cultured with CM harvested from estrogen treated BPH-1 cells.The mRNA levels of collagen Ⅳ and smoothelin increased in stromal cells treated with CM from BPH-1 cells.The results of radioimmunoassay also showed that the collagen Ⅳ protein level up-regulated in the supernatants and cell extracts of CM-treated stromal cells.A neutralizing antibody to TGF-?1 inhibited the stimulation of collagen Ⅳ and SMMHC by BPH-1 CM.The expression of fibronectin was only marginally changed in stromal cells cultured in the presence of BPH-1 CM.CONCLUSION:The BPH-1 cells increase ECM accumulation and differentiation of stromal cells through TGF-?1.Estradiol stimulate differentiation of stromal cells by induction of TGF-?1 expression.Estradiol stimulate proliferation by influencing the factors secreted from prostatic epithelial cells.

Two recombinant plasmids pVAX/Sj23 and pVAX/mIL-18 containing Schistosoma japonicum 23 000 membrane protein (Sj23) and murine IL-18 were evaluated for their ability to induce immune responses and to protect against S. japonicum challenge in mice. All animals vaccinated with pVAX/Sj23 alone or plus pVAX/mIL-18 developed specific anti-SWAP (soluble worm antigen preparation) ELISA antibody and splenocyte proliferation response,and co-injection of pVAX/mIL-18 significantly increased the production of IFN-γ and IL-2 compared with pVAX/Sj23 alone, indicating that IL-18 enhances the Th1-dominant immune response. The challenge experiment showed that worm reduction rates in pVAX/Sj23 group compared with control group (pVAX1) was 26.5% and in the pVAX/Sj23 plus pVAX/mIL-18 group was 41.9% ,and the hepatic egg reduction rates were 42.7 and 49.6%,respectively. These results indicated that co-injection of an IL-18 plasmid with Sj23 DNA vaccine efficiently improves the protective effect against S. japonicum infection.
