Metastatic tumors to the nasal cavity and paranasal sinuses are far less common than primary cancer in this location. The digestive system malignant tumor metastasis to the nose is rarer. The clinical presentation of metastases is similar to that of primary tumors and common symptoms include recurrent epistaxis, nasal obstruction and facial pain. Metastases to the nose and paranasal sinuses usually respond poorly to treatment and have a poor prognosis.

OBJECTIVE: To explore the effects of Pollen Typhae total flavones (PTF) on the mRNA expressions of peroxisome proliferator-activated receptors (PPARs) alpha,gamma, beta/delta so as to analyze its possible mechanism in improving the insulin sensitivity of 3T3-L1 adipocytes. METHODS: Adipocytes were treated with PTF, and expressions of PPARalpha, PPARgamma, PPARbeta/delta mRNAs relating to the adipocyte glucose and lipid metabolism were determined by reverse transcription polymerase chain reaction. RESULTS: PTF obviously up-regulated the expressions of PPARalpha and PPARgamma mRNAs, all showing significant differences as compared with those in the normal control group (P<0.01). CONCLUSION: With its function as an insulin sensitizer, PTF may enhance the PPARalpha and PPARgamma mRNA expressions in 3T3-L1 adipocytes.

Objective To compare bolus infusion and replenishment using real low mechanical index contrast enhanced ultrasound in assessing the change of renal cortical perfusion.Methods Using dopamine (i.v.) at the dose of 0.5,2.0,5.0μg · kg- 1 · min- 1 to change renal blood perfusion of 20 rabbits,then during bolus or contant injection of SonoVue,at coded pulse inversion mode,real-time contrast ultrasound was performed,the latter method needed destroying microbubble at a high MI when amplitude reach a steady state,then recording the replenishment,peak intensity(A) and time to peak (PPT) were obtained through raw time-intensity curve,and slope rate of TIC(k) was acquired by curve fitting,standard effective renal plasma flow(ERPF) was measured through 4-aminohippuric acid clearancerate method,meanwhile correlations between ERPF and parameters were analyzed,as well as the paired samples t test for each parameter before and after dopamine administration.Results The ascending branchs of raw TIC of bolus infusion increased sharply and were approximately straight,then descended gradually,while that of replenishment looked like two straightlines with different slopes,then stayed horizontal Both the value of A of two methods were positively correlated with ERPF ( r b =0.85,r re =0.66),and were different at the same ERPF,meanwhile the value of TTP were negatively correlated with ERPF( r b =-0.92,r re =- 0.76),and there were no statistically difference between the two methods.k from Gamma fitting was far from correct,while k from exponential fitting was apparently correlated with ERPF ( r re =0.77 ).Conclusions Both bolus injection and constant injection-replenishment method can assess renal cortical blood perfusion,TIC parameters A and TTP represent regional blood volume fraction and microbubble velocity respectively.Bolus-infusion with real low mechanical index is more precise and available.Comparing with k,TTP is more appropriate to reflect perfusion velocity.

Objective To investigate the effects of transplantated tumor capillary permeability under microbubble enhanced diagnostic ultrasound exposure.Methods Fourty eight rats were randomly divided into four groups after Walker 256 carcinomas were subcutaneousely implanted,named the control group (A),microbubbles group (B),ultrasound group (C),microbubbles and ultrasound group (D).Using Evans blue(EB) as the indicator for tumor capillary permeability,the microbubbles were injected through the vein with diagnostic ultrasound frequency as 1.75 MHz,mechanical index as 1.4.The spillover of EB was estimated under confocal laser microscope,meanwhile the contents of EB in the tumor tissues were calculated according to the standard curve and spectrophotometry.Results EB spillover was observed around the capillaries in the group D,while EB spillover was only observable on capillary in group A,B and C.The EB content was also significantly higher than those in group A,B and C.Conclusions Exposure to both diagnostic ultrasound and microbubbles results in increased capillary permeability of rat tumor tissues,which might become a potential therapeutic method on clinical chemotherapy.

Objective To investigate the feasibility of transfecting gene into HepG2 by therapeutic ultrasound combined with microbubble,and to explore the optimal ultrasonic parameters for high transfection efficiency.Methods HepG2 cells were cross-interval planted in 24-well plates.EGFP plasmid DNA and microbubbles were added to the cultured HepG2 and three parameters of the therapeutic ultrasound were optimized.Firstly,set ultrasonic intensity gradient (group A,from A1 to A5),which were 0.4 W/cm,0.8 W/cm2,1.2 W/cm2,1.6 W/cm2 and 2.0 W/cm2 respectively.Secondly,set the duty cycle gradient group (group B,from B1 to B3),which were 10％,20％ and 50％ respectively.Lastly,set the exposure time group(group C,from C1 to C3),which were 30 s,90 s and 180 s.After 24 hours,the expression of GFP was observed by fluorescence microscopy,the transfection rates was detected by flow cytometry,the cell death were assessed by trypan blue exclusion.Results The plasmid transfection efficiency was varied under different ultrasonic parameters.Within a certain range,the increasing of parameters can improve the transfection efficiency,but when the parameters were too large (eg.the intensity＞1.6 W/cm2 or 50％ duty cycle),the actual transfection efficiency decreased due to the increased cell death.When the ultrasonic intensity was 1.2 W/cm2,the transfection efficiency and mortality were better than the other subgroups of group A.When the duty cycle was 20％,the transfection efficiency and mortality rate were better than the other subgroups of group B.Continue to increase the exposure time over 90 s was not statistically significant (P ＞0.05) for transfection efficiency and cell mortality.Conclusions The ultrasound-targeted microbubble destruction is an efficient method for gene delivery in vitro.The transfection efficiency vary greatly under different parameters,so optimization parameters is conducive to the promotion of gene transfection.

Objective To evaluate the anti-cervical carcinoma cells effects of oncolytic adenovirus d/1520 and Ad-Endo in vitro,and investigate the influence of d/1520 on the Endostatin expression directed by Ad-Endo in cervical carcinoma cells.Methods After cervical carcinoma cells were infected with d/1520 or/and Ad-Endo,the cytopathic effects (CPE) were observed,and the cytotoxicities were measured by MTT assay.Endestatin concentrations were measured by ELISA.Results d/1520 can replicate in cervical carcinoma cells and induce cytopathie effects; In MTT assay,Ad-Endo hardly inhibited the growth of cervical carcinoma cells,while d/1520 inhibited efficiently the proliferation of cervical cancer cells.And the inhibitory rates in Ad-Endo + d/1520 group were higher than that in d/1520 group.Ad-Endo expressed Endestatin protein in cervical cancer cells,while Endostatin concentrations in Ad-Endo+dl1520 group were much higer than those in Ad-Endo group.Conclusions dl1520 can kill cervical carcinoma cells in vitro,and this eytotoxieity can be enhanced by combining with Ad-Endo.The expression of Endostatin directed by Ad-Endo in cervical cancer cells can be dramatically increased by dl1520.
