Objective The experimental study on the lift-up speed of a new kind of compliant aerodynamic foil thrust bearings was performed on the multifunctional test rig established for testing the performances of foil gas bearings. Methods The lift-up speed of foil gas thrust bearing under given axial load was analyzed through the spectrum of axial displacement response in frequency domain. Results The test results indicated that the difference in the spectrum of axial displacement responses before and after lifting up of the rotor was obvious. After lifting up of the rotor, there were only larger components of rotation frequency and lower harmanic frequencies. If the rotor wasn't lift-up, there were also larger components of other frequencies in the spectrum. Conclusion So by analyzing the spectrum of axial displacement response, the results showed that the lift-up speed was about 1 860 rpm when the axial load was 31N.

Purpose To investigate the effect of 5'-nucleotidase from Trimeresurus albolabris venom on platelet aggregations and its mechanism.Methods Piatelet aggregations induced by ADP,AA and PAF,respectively.were measured by turbidimetric method after platelet incubated with 5'-nucleotidase.Results 5'-nucleotidase significantly inhibited platelet aggregations induced by ADP,AA and PAF in a dose-dependent manner.Washed platelet inhibition experiment and the effect of Adenosine,CP/CPK on platelet aggregations showed that platelet aggregations inhibited by 5'-nucleotidase were associated with ADP hydrolysis and adenosine accumulation.The effect of ASA on platelet aggregations showed that the enzyme inhibited platelet aggregations probably by blocking the formation of TXA2.Conclusion 5'-nucleotidase from Trimeresurus albolabris venom inhibited platelet aggregations through ADP hydrolysis and adenosine accumulation,and maybe it is related to blocking the formation of TXA2.

Aim To evaluate the potency of anti-D. acutus venom IgY neutralizing the main activities of D. acutus venom.Methods After mixing the different a-mounts of IgY with snake venom and incubating togeth-er,the main activities of snake venom were assayed by biochemical methods.Results The in vitro assays in-dicated that anti-D.acutus venom IgY obviously neu-tralized the activities of PLA2 ,5′-nucleotidase,hyalu-ronidase,metalloprotease and serine proteinase (fi-brinogenase)in D.acutus venom.Mouse experiments showed that the ED50 value of IgY for mouse was 1 131.09 μg.Conclusion Anti-D.acutus venom IgY antibodies have good effects in neutralizing D.acutus venom without the toxicities themselves.

Objective To compare the effect of diversification rehabilitation team mode on function in patients with cerebral infarction. Methods Sixty-six patients with cerebral infarction were divided into diversification rehabilitation team mode group (diversification group) and routine rehabilitation mode (routine group) according to the rehabililation method with 33 cases each. All patients of 2 groups were treated for 2 weeks. Evaluations were made before and after treatment. The simplified Fugl-Meyer motor function rating scale was used to evaluate motor function, modified Barthel index was used to evaluate activities of daily living, and MOS 36-item short form health survey was used to evaluate quality of life;and 0-100 digital simulation assessment was used to evaluate patient satisfaction after treatment. Results The simplified Fugl-Meyer motor function rating scale score, modified Barthel index score, MOS 36-item short form health survey score and patient satisfaction rate after treatment in diversification group were significantly better than those in routine group: (76 ± 4) scores vs. (63 ± 3) scores, (65 ± 3) scores vs. (52 ± 4 ) scores, (57 ± 7) scores vs. (44 ± 6) scores, (92 ± 5) scores vs. (77 ± 3) scores, and there were statistical differences (P<0.05). Conclusions Both kinds of rehabilitation model can promote functional recovery in patients with cerebral infarction, but diversification rehabilitation team model is better than conventional model.

Objective To investigate the character of aquaporin-1(AQP-1)expression in adrenal gland in diabetes mellitus and evaluate adrenal gland damage and function alterations by DWI with multiple b values. Methods Twenty male Sprague-Dawley rats were randomly selected by computer and randomized into 2 groups:untreated controls(n=10)and diabetes(DM)(n=10). Rats in diabetes group were fed with high-sucrose and high-fat diet, controls were fed with common diet. After fed with high-sucrose and high-fat diet for 4 weeks, rats in diabetes group were injected with streptozotocin(STZ). Forty days after diabetes induction with streptozotocin(STZ), MR imaging was performed in a 7.0 T scanner. Venous blood from the tails was collected before MRI scan to measure blood glucose, blood glucose more than 16.7 mmol/L wasregarded as diabetic status. All the rats underwent DWI with 18 b values(0 to 4500 s/mm2). Maps of pure diffusion coefficients(D), pseudo-diffusion coefficients(D*)and ultra-high ADC(ADCuh)were acquired. Rats were sacrificed after MRI scan for adrenal gland histopathology, AQP-1 immunohistochemistry analysis and AQP-1 optical density(OD)measurements. Student t test was used to compare the difference of D*, D, ADCuh and OD of AQP-1 between two groups. Results Eight diabetic animals developed hyperglycemia(two rats died during the modeling process). MRI scan was performed in all of the 18 rats. Signal intensity of D*map, D map and ADCuh map decreased gradually. ADCuh increased significantly in DM animals(0.24 ± 0.06) × 10-3mm2/s compared with control animals(0.18 ± 0.07) × 10-3 mm2/s(P<0.05), whereas there was no significant difference found between the two groups in their respective D*and D values(P>0.05). There was a noticeable increase in the AQP-1 labeling in the adrenal cell membrane and cytoplasm in DM animals compared with control animals. DM rats showed an increased OD value of AQP-1 in adrenal gland compared with the control animals(P<0.05). Conclusions We found significantly higher AQP-1 expression in adrenal gland in DM animals compared with controls. Ultra-high b-Values DWI may work as a useful way for noninvasive evaluation the change of adrenal function in DM.
