Objective To assess clinical efficacy of comprehensive treatment on chronic sinusitises (CRS) with neutro?phils infiltration and eosinophilic infiltration as pathological features. Methods A total of 256 CRS patients whose symp?toms were not been improved after surgery (visual analog scale>6,3 months after surgery) were included in this study. Dif?ferent comprehensive treatments were given to the patients according to the different types of cell infiltration. The visual ana?log scale (VAS), Lund-Kennedy and nasal histopathological examination were observed after treatment in patients. Results After different comprehensive treatments, the VAS and Lund-Kennedy were improved in patients with eosinophils infiltra?tion, but the number of eosinophils was not reduced. The VAS, Lund-Kennedy and the number of neutrophils were signifi?cantly improved in patients with mainly neutrophils infiltration. Conclusion According to different immune pathological characteristics, patients of CRS should be given different comprehensive treatments. There is a obvious efficacy for patients with neutrophil infiltration.

Objective:To study the expression of Ets-1 and VEGF in breast invasive ductal carcinoma (IDC) tissues,and to analyze its correlation with clinicopathologic characteristics of IDC. Methods:Forty breast IDC tissues and their adjacent normal tissue samples were obtained from clinical diagnosed breast IDC patients after surgery. Expression of Ets-1 and VEGF protein and mRNA was examined by immunohistochemistry and RT-PCR. Results:(1)Expression of Ets-1 and VEGF protein in breast IDC tissues was significantly higher than that in adjacent normal tissues (P

Objective To study the characteristics of vestibular autorotation test (VAT) in patients with the posterior circulation transient ischemic attacks(PCTIA) ,further reveal the pathogenesis vestibular function damage because of PCTIA .Methods VAT was performed on 41 patients with posterior circulation transient ischemic at‐tacks(PCTIA group) and 30 healthy controls(control group) .Parameters analyzed included gains ,phases and a‐symmetry of VAT .The positive result of the test could be defined if any of the paramaeters was abnormal .Results In the PCTIA group and control group ,gains were enhanced without being reduced as showed in 25 (62 .5% ,25/40) cases and 5(16 .7% ) ,respectively (χ2 =7 .09 ,P<0 .01) ,gains were enhanced with reduced as showed in 10(25% ) cases and 0(0% ) ,respectively (χ2 =8 .78 ,P<0 .01) .Conclusion The results of VAT in patients with the PCTIA can show gains enhanced with reduced in different frequency .VAT can provide valuable reference on positioning as‐sessment of vestibular system damage in patients with PCTIA .

Objective To investigate tissue distribution of Hylotelephin in Beagle dogs and excretion of Hylotelephin in rats. Methods A high performance liquid chromatography (HPLC) with UV detection was developed to study the concentrations of Hylotelephin in biological samples, taking anthracene as an internal standard, Benzoyl chloride as the pre-column derivatization of Hylotelephin and methanol-water as the mobile phase. Results After a single intravenous dose of 10.6 mg/kg Hylotelephin in beagle dogs, parent drug was widely distributed to virtually all tissues in 5 min and the concentration of Hylotelephin in most tissues at 90 min were lower than those at 5 min obviously. Hylotelephin was mainly distributed in kidney, liver and spleen, secondly in heart, lung and intestine. The parent drug concentration in kidney, liver and spleen was similar to that in blood at the same time point. After a single intravenous dose of 36 mg/kg Hylotelephin in rats, the excretion of the parent drug in urine, feces and bile amounted to 88.45%, 0.61% and 1.08% of the dose, respectively. The parent drug excretion amounted to 67% of the dose in 3 h. Conclusion Hylotelephin was distributed and eliminated in Beagle dogs rapidly. It was mostly distributed in kidney, liver, spleen and plasma. The parent drug excretion was 88% via urine.
