RESUMO

Objective To assess the effect of magnetic resonance imaging (MRI) on preoperative staging of endometrial carcinoma and depth of myometrial invasion. Methods Fifty-six patients with endometrial carcinoma were underwent conventional and contrast-enhanced MR scan. The results of pathology , MRI examinations of preoperative staging and depth of myometrial invasion were assessed and compared. Results The accurate rate of MRI diagnosis in preoperative staging diagnosis was 82.1% (46/56) and the consistency check as Kappa was 0.771 (P < 0.001). Conclusions MRI may be a good diagnostic tool with high sensitivity and specificity for assessing myometrial invasion and detecting tumour extension and should be considered as a routine part of the preoperative assessment in all patients with endometrial carcinoma.

RESUMO

OBJECTIVE: To study the formulation and technology of dexamethasone solid lipid nanoparticles(DXM-SLN) lyophilized injection and evalnate it's quality. METHODS: The formulation of the supporting agent was optimized and the preparation technology of lyophilized injection was established to prepare the lyophilised injection. The content of DXM in the sample was determined and its quality was investigated as well. RESULTS: 30% mannitol was supporting agent, the particle size of DXM-SLN was 340 nm, with zeta potential at -25.2 mV, entrapment ratio at 92.10% and drug-loading at 7.10%. It was stable within 3 months' at 2~8 ℃storing. CONCLUSION: The preparation technique of this preparation is simple and feasible and its quality is stable and controllable.

RESUMO

OBJECTIVE: To establish a RP-HPLC method for the determination of preservative ethylparaben content in hospital preparation.METHODS: The determination was carried out on Spherisorb C18 column and the mobile phase consisted of acetonitrile-water(50∶50,V/V) at a flow rate of 1 mL?min-1.The column temperature was set at 35 ℃;the detection wavelength was set at 254 nm and the sample size was 20 ?L.RESULTS: The linear range of ethylparaben was 1.812 5~18.125 0 ?g?mL-1(r=0.999 9) with an average recovery rate of 99.92%.The intra-day RSD was less than 2.10% and inter-day RSD was less than 4.89%.CONCLUSION: The method is simple,rapid and accurate,and applicable for the determination of ethylparaben content in hospital preparation.
