Objective Experimentally to investigate the changes in vasospastic canine basilar arteries. Methods Vasospasm of basilar arteries was induced by double-injecting autologous blood into the brain cisterns. 28 adult mongrel dogs of both genders served as the subjects, of them 20 involved in experimental group and accepted the PTA treatment and the other 8 doges were in negative control group without any treatment. PTA was performed by a single inflation of balloon for 10 seconds at a peak pressure of 2.0 atmospheres. Angiography was re-performed at 30 day, 90 day and 300 day following PTA, respectively. The histologic changes were then evaluated using light and electron microscopy. Results Caliber of basilar arteries of all canines decompressed obviously, from 1.3 mm to 0.8 mm. In test group, PTA succeeded in 15 ones, with caliber of vasospastic basilar arteries enlarged obviously after PTA ( P

Objective To develop the specific module of quality of life instrument for patients with esophageal cancer. Methods with the structured group ( nominal group and focus group) methods and the qualitative and quantitative theory and methodology in developing rating scales, items were preliminary screened, evaluated and modified. And the data measuring from 28 cases of esophageal cancer patients and 25 doctors/nurses were analyzed by 4 statistical procedures: method of coefficient of variation, correlation analysis, patients'importance rating procedure and doctors' importance rating procedure. Results By above statistical procedures and advises of doctors, thus 19 - items specific module was formed finally. Conclusions The specific module developed on the strict procedures has good content representativeness and validity.

OBJECTIVE:
To evaluate the effect of two surgical methods on treatment of allergic rhiniti complicated with nasal septum deviation.
METHOD:
Eighty-seven cases of allergic rhiniti complicated with nasal septum deviation were divided into 2 groups according to the degree of mucosal hypertrophy and hyperplasia of bone in inferior turbinate. They were treated by resection of nasal septum deviation combined with temperature-controlled radio-frequency, or combined with partial submucoperiosteous resection of inferior turbinate bone. The Lanzhou standard (2004) and nasal airway resistance were used to evaluate the efficacy.
RESULT:
After one year follow-up time, the nasal resistance was significantly decreased and the effective rates were greater than 88% in each group.
CONCLUSION
Both of the two surgical methods can significantly depress the nasal resistance and improve the allergic symptoms, which shows good effect.

The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.
