OBJECTIVE To investigate the effect of different respiratory mask pressure on the upper airway volume(UAV),and to compare the changes of UAV between patients with obstructive sleep apnea hypopnea syndrome(OSAHS)and normal adults. METHODS Thirty three patients with OSAHS and thirty normal adults were included in this study.CT scan evaluated the UAV from roof of nasopharynx to glottis.UAV under different respiratory mask pressure between patients with OSAHS and normal adults were compared.RESULTS Patients with OSAHS had less UAV,and changes of UAV per cmH_2O were significantly smaller in patients with OSAHS than normal adults.CONCLUSION The results suggest that the quantitative data of UAV and changes of UAV per cmH_2O can be obtained.Upper airway anatomic narrowing and reduced airway distensible degree are major etiological factors for OSAHS.

BACKGROUND: Cirrhosis can cause severe effect on spinal cord or other tissue and organ sometimes.OBJECTIVE: To establish cirrhosis model with rat liver injured by tetrachloride so as to investigate the distribution of nitric oxide synthase (NOS)in spinal cord of rats with cirrhosis.DESIGN: Completely randomized controlled study.SETTING: Anatomy Department of Capital University of Medical Sciences.MATERIALS: The experiment was completed at the Anatomy Department of Capital University of Medical Sciences from March 2002 to December 2003. Totally 20 male Wistar rats were divided randomly into cirrhosis group and normal group with 10 in each group.METHODS: Cirrhosis model in cirrhosis group was established with rat liver injured by tetrachloride, but rats in normal group were not treated with any method. After 3 months, total rats in the two groups were perfused and fixed; meanwhile, tissue of spinal cord was taken out for section.Quantity and gray degree of NOS positive cell in spinal cord of rats with cirrhosis were measured with nicotinamide adenine dinucleotide hydrogen phosphate-diaphorase (NADHP-d) histochemical method and Leica Q500IW image analysis system.MAIN OUTCOME MEASURES: [1] Gray degree of NOS positive neurons of rats in the two groups; [2] Distribution of NOS positive cell of rats in the two groups.RESULTS: Twenty rats all entered the final analysis. [1] Gray degree of NOS positive neurons of rats in the two groups was 60 (P ＞ 0.05). [2] In the area of gray matter of spinal cord, NOS positive cells were mainly distributed over the circumference of central canal, i.e. the Ⅹ layer of spinal cord and intermediolateral nucleus. Color of NADHP-d was positive, and the cellular form was shaped in triangle and fusiform. Cellular nucleus was not colored but color of cytoplasm was deep. The size of cells was moderate mainly of 25 μm. NOS positive cells were generally distributed averagely over intermediate zone of gray matter in cervical, thoracic and lumbar spinal cord and had no specific changes.CONCLUSION: Expression of NOS in spinal cord of rats in the cirrhosis group and the normal group is probably identical. Distributive characteristics of nitrogen monoxide (NO) in spinal cord suggest that adjustment on low sympathetic nerve of rats with cirrhosis is not different from that of the normal.

Executive function is an important advanced cognitive process, and it is the function that integrates different cognitive processes to achieve one's aim. Updating is an important component of executive function. According to the classifications of Miyake & Colletee on executive function, two study paradigms on memory updating are discussed: n-back paradigm & running memory paradigm. A new study method called latent variable analysis and new studies of cognitive neuroscience on memory updating are introduced. Issues on ethics and morality in research on cognitive experiment of psychology are briefly demonstrated to explore appropriate direction for research of executive function in future.

Objective To investigate the relationship between serum uric acid(SUA)and clinic characteristics and result of coronary artery angiography of patients with coronary heart disease(CHD).Methods Two hundreds and seven patients for coronary artery angiography were divided into CHD group and control group.Their clinical data and results of coronary artery angiography were analyzed through statistics.Results SUA levels of CHD patients were significantly higher than the control subjects SUA(P

Objective To evaluate the value of three-dimensional color power angiography(3D-CPA,) in osteosarcoma diagnosis. Methods Forty-three cases with osteosarcoma were detected with 3D-CPA to assess the vascular classification(3D-CPA Ⅰ to Ⅲ) and measure the vascular parameters including vascularization index(VI), flow index(FI) and vascularization-flow index(VFI). Results All of the 43 cases were classified into 3D-CPA Ⅲ type. The space structure shape of blood vessels and the origin of nutrient vessels was clear. The quantitative measurement showed that VI was 25.84±6.87,FI was 34, 18±2.93, VFI was 9.02±4.04. Conclnsions It is a new method to analyze and diagnose osteosarcoma with 3D-CPA because it can show the nutrient vessels and the embranchments of blood vessels clearly, tridimensionally and integrally and Bake quantitative or partial-quantitative analysis.

Objective To evaluate the effects of different types of extracorporeal circuits (ECCs) on the concentrations of sufentanil in the priming solution.Methods The experiment was performed in three groups (n =6 each).Two types of ECCs were used:Xi-jing type 90 oxygenator (group Ⅰ) and Termo Capiox SX18 membrane oxygenator (group Ⅱ),while in control group (group Ⅲ) a glass container was used.The ECC and glass container were filled with the priming solution (succinylated gelatin 1000 ml + lactated Ringer' s solution 1000 ml).Sufentanil 15 μg (concentration 7.5 ng/ml) was then added to the priming solution.The priming solution was circulated in the closed ECC or stirred in the glass container.The concentration of sufentanil in the priming solution was determined by gas chromatography-mass spectrometry at 3,5,10,20,30,40,50,60,70,80 and 90 min after addition of sufentanil.Results The concentration of sufentanil in the priming solution was significantly decreased at the different time points in groups Ⅰ and Ⅱ as compared with group Ⅲ (P ＜ 0.05).The concentration of sufentanil in the priming solution was significantly lower at each time point in group Ⅰ than in group Ⅱ (P ＜0.05).Conclusion Both the two types of ECCs can absorb sufentanil and the adsorption of Xi-jing type 90 oxygenator is stronger than that of Termo Capiox SX18 membrane oxygenator.

Objective To investigate the changes and correlation between platelet activation and inflammatory response in patients with essential hypertension(EH). Methods Sixty-one patients with essential hypertension and sixty-four patients with paroxysmal supraventricular tachycardia as control group were enrolled in the study. The levels of high sensitivity C reactive protein ( hs-CRP ) and mean platelet volume ( MPV ) were measured and compared between the control group and the essential hypertension group. Results Compared with the control group,the levels of hs-CRP and MPV in the EH group were significantly higher( [3.51 ± 1.95]mg/L vs [ 1.15 ± 0. 77 ] mg/L, P ＜ 0. 05 ). The MPV in the EH group was significantly higher than that in the control group ( [ 11.29 ± 2. 18 ] flvs [ 9. 20 ± 2. 31 ] fl, P ＜ 0. 05 ). The level of hs-CRP positively correlated to the level of M PV (r = 0. 452, P = 0. 003 ). Conlusions There were inflammatory response and platelet activation in patients with EH and the serum levels of hs-CRP and MPV is correlated with the development of essential hypertension.

Postoperative ileus is commonly referred to the inhibition of gastrointestinal motility after ab-dominal surgery. Some causes are responsible for the ileus, including postoperative pain and electrolyte im-balances, and manipulations during surgery. Although gastrointestinal motility normalizes spontaneously in most patients, some develop severe to postoperative ileus, which is difficult to treat, with a delayed recovery from surgery, prolonged hospital stay, and increased treatment costs. So, it is essential to understand the mechanisms of postoperative ileus for effective prevention and treatment.

Objective To investigate the predictive value of epicardial adipose tissue(EAT) thickness for the recurrence of atrial fibrillation (RAF) after concomitant valve replacement and bipolar radiofrequency ablation.Methods From January 2012 to May 2014,156 patients with permanent atrial fibrillation and organic valvular diseases underwent concomitant valve replacement and successful bipolar radiofrequency ablation in the First People's Hospital of Shangqiu.After 1 year of follow-up,the recurrence of AF was analyzed and the correlation factors were analyzed statistically.Results All patients completed a regular follow-up.During a 12-month follow-up period,RAF was observed in 39 patients (25.0％).Echocardiography-derived regional EAT thickness was significantly greater in RAF patients than that in non-RAF patients((6.9±0.6) mm vs.(5.5±0.7) mm,t=4.649,P＜0.05).The EAT thickness strongly correlated with patients age,body mass index,Ratio of left atrial diameter,mitral diastolic blood flow velocity and early diastolic velocity of mitral annulus,low density lipoprotein-cholesterol and thyroglobulin (r =0.62,0.57,0.68,0.59,0.73,0.76;P ＜ 0.05).Cox multivariable analysis showed that,duration of AF history (95％CI:1.01-1.15,P =0.040),left atrial diameter (95％CI:1.07-1.24,P =0.021) and EAT thickness (95％CI:1.05-1.79,P =0.009) were independent predictors of RAF.Conclusion Echocardiography-derived regional EAT thickness combined with left atrial diameter may serve as effective parameters in identifying patients at the highest risk for RAF.
