OBJECTIVE: To measure the upper airway of obstructive sleep apnea-hypopnea syndrome by speed CT. We can predict the airway obstruction plane with the airway plane data and compliance in OSAHS patients. Through this measurement, we can provide assistance for clinical diagnosis and treatment. METHOD: This study randomly selected 82 patients diagnosed with OSAHS and 45 cases non-snoring healthy people as control group by the PHILIPS 256-slice CT. The zone volume, sagittal diameter, coronary diameter and cross-sectional area of the narrowest plane in nasopharyngeal area, velopharyngeal area, glossopharyngeal area, hypopharynx area in two groups of quiet respiration and Müller's status were measured. RESULT: In the OSAHS group underwent quiet breathing and Müller movement during CT scanning, the two states about nasopharyngeal coronary diameter, the hypopharynx sagittal diameter and cross-sectional area showed no significant difference, while other groups showed differences between the parameters (P<0.05). There was significant difference (P<0.01) in the velopharyngeal volume, tongue sagittal diameter and volume. Under Müller movement in the OSAHS group and the control group, the hypopharynx volume showed no significant difference. The nasopharyngeal coronary diameter and volume, velopharyngeal cross-sectional area and tongue sagittal diameter were different (P<0.05). The remaining set of parameters showed significant differences (P<0.01). Compared the airway compliance (Müller phase) of the OSAHS group and the control group,the parameters of each group were different (P<0.05), of which the nasopharyngeal sagittal diameter, velopharyngeal volume showed significant difference (P<0.01). Meanwhile, in the same plane, coronary diameter was greater than sagittal diameter (P<0.05) in both the OSAHS group and the control group. The pharyngeal volume measurement was basically consistent to the fiber endoscopy. CONCLUSION The obstruction plate of OSAHS patients is mostly in the velopharyngeal area and glossopharyngeal area measured with a high speed CT. The volume measurement of upper airway with speed CT can predict airway obstruction plate in patients with OSAHS.

Objective: To explore the effects of various concentrations IFN-? on human oral epidermic cancer cell line KB and its multidrug resistant counterpart KBv200.Methods: The toxicity of IFN-? and/or VCR was assayed by MTT method; intracellular rhodamin123 concentration and p-glycoprotein expression were measured by flow cytometry; mdr-1 mRNA was assayed by RT-PCR. Results: High-dose IFN-?(10 000 IU/ml) had significant antiproliferative effects on KB/KBv200 cell lines. Low-dose IFN-? did not have any significant effect on growth of KB/KBv200 cells, but did increase the cytotoxic effect of VCR and the accumulation of Rhodamine123 in KBv200 cell line and had no effect on parent VCR-sensitive KB cell line. IFN-? down-regulated expression of P-gp and mdr-1mRNA . Conclusions: IFN-? has significant effect on the reversal of multidrug resistance of KBv200 cell line via a mechanism of P-gp and mdr1 mRNA down-regulation.

Objective To evaluate the effect about medication compliance for patients with chronic heart failure in outpatients using nursing intervention model based on Omaha system.Methods 100 patients were randomly divided into observation group(50 patients)and control group(50 patients).The two groups of patients were given routine nursing intervention,the observation group also used the Omaha system to develop care programs on this basis, and was given the implementation about continuity of care.Results On the point of the two or three months after the patients were discharged,the AHFKT -V2 questionnaire scores in the observation group[(17.690 ±1.892)points, (20.900 ±2.052)points]were significantly higher than the control group[(14.080 ±2.374)points,(18.450 ± 1.781)points],the differences were statistically significant (t =-8.488,-6.442,all P <0.05).However,the same as the points after the patients were discharged,Morisky questionnaire scores in the observation group[(1.036 ± 0.780)points,(0.487 ±0.260)points]were significantly lower than the control group[(1.54 ±1.182)points, (0.920 ±0.804)points],the differences were statistically significant(t =3.420,4.965,all P <0.05).Conclusion The use of Omaha system to develop the targeted continuity of care,can improve the patients medication compliance.

OBJECTIVETo explore the mechanisms of aluminum (Al)-induced neurotoxicity by studying the effect of aluminum on lipid peroxidation in rat's brain and its sex related difference.

METHODSForty SD rats, both male and female, were exposed to aluminum through intraperitoneal injection of AlCl3 solution for 60 days at different dose. After exposure, the step down test was performed to examine the learning and memory abilities of rats, and the activity of superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in rat's cerebrum were detected by chemical method. The changes of ultrastructure in cortex were observed by transmission electron microscopy.

RESULTSThe differences between the changes of all indexes of female and male rats in the same dose-group wasn't statistically significant (P > 0.05). Compared with the rats in the control group, the learning and memory abilities of the Al-exposed rats were significantly decreased (P < 0.05). The content of MDA was increased (P < 0.01) while the activity of SOD was decreased (P < 0.05). The membrane structure of neurons in cerebrum cortex of the Al-exposed rats were broken, dissolved and gone.

CONCLUSIONAluminum can accelerate lipid peroxidation in rat's brain, which may be one of the important intoxication mechanisms of aluminum. However, the sex-related difference of this effect have not yet been observed.
