ABSTRACT
Objective:To explore the clinical efficacy of modified Ditantang combined with acupuncture in the treatment of dysphagia after apoplexy （DAS） syndrome of phlegm and blood stasis blocking collaterals. Method:One hundred and eight patients were randomly divided into control group （54 cases） and observation group （54 cases） by number table. Both groups underwent nutritional management，rehabilitation training and acupuncture. Patients in control group additionally took Tongluo Huatan capsules， 3 granules/time， 3 times/day， while patients in observation received modified Ditantang. Both groups had two weeks of treatment. The Kubota's drinking water test， swallowing contrast examination （VFSS）， and standard swallowing function assessment （SSA） were conducted. Swallowing disorder specific quality of life scale （SWAL-QOL） and sputum collateral stasis syndrome were scored before and after treatment. The levels of brain-derived neurotrophic factor （BDNF）， nerve growth factor （NGF） and neuron-specific enolase （NSE） before and after treatment. The occurrence of pneumonia， malnutrition， dehydration and aspiration were then recorded. Result:The clinical effective rate was （47/49） 95.92%in the observation group， higher than （41/50） 82.00% in the control group's （<italic>χ</italic><sup>2</sup>=4.854，<italic>P</italic><0.05）. The grade of Kubota's drinking water test in observation group was lower than that in the control group（<italic>Z</italic>=2.211，<italic>P</italic><0.05）. VFSS swallowing dysfunction in observation group was lighter than that in control group（Z=1.969，<italic>P</italic><0.05）. The scores of Kubota's drinking water test， SSA and phlegm and blood stasis blocking collateral syndrome in the observation group were all lower than those in the control group（<italic>P</italic><0.01）， while the VFSS score was higher than that in control group （<italic>P</italic><0.01）. The swallowing symptom score， other symptom scores and total SWAL-QOL scores of the observation group were higher than those of the control group（<italic>P</italic><0.01）. The levels of BDNF and NGF in the observation group were higher than those in the control group （<italic>P</italic><0.01）， but the NSE level was lower than that in the control group（<italic>P</italic><0.01）. The complication rate in the observation group was （6/49）12.24%， which was lower than （15/50）30.00% in the control group（<italic>χ</italic><sup>2</sup>=4.668，<italic>P</italic><0.05）. Conclusion:On the basis of nutrition management and rehabilitation training， modified Ditantang combined with acupuncture can reduce the risk of dysphagia and aspiration， improve the degree of neurological deficits， improve the quality of life， and reduce complications in treatment of DAS syndrome of phlegm and blood stasis， with significant clinical efficacy.
ABSTRACT
The forced oscillation technique (FOT) is a noninvasive method for respiratory mechanics measurement. For the FOT, external signals (e.g. forced oscillations around 4-40 Hz) are used to drive the respiratory system, and the mechanical characteristic of the respiratory system can be determined with the linear system identification theory. Thus, respiratory mechanical properties and components at different frequency and location of the airway can be explored by specifically developed forcing waveforms. In this paper, the theory, methodology and clinical application of the FOT is reviewed, including measure ment theory, driving signals, models of respiratory system, algorithm for impedance identification, and requirement on apparatus. Finally, the future development of this technique is also discussed.

<p><b>OBJECTIVE</b>To investigate the role of lycium bararum polysaccharides (LBP) on angiotensin II (AngII)-induced senescence of human umbilical vein endothelial cells (HUVECs) and expressions of P53 and P16 and explore the mechanism of LBP against aging.</p><p><b>METHODS</b>HUVECs cultured in vitro were stimulated with 1×10(-6) mmol/L AngII to induce cell senescence, which was identified using β-gal staining. Flow cytometry was used for analyzing the cell cycle changes, and the cell viability was assessed using CCK-8 method. Western blotting was employed to detect the expression of P53 and P16 in the exposed cells.</p><p><b>RESULTS</b>Compared with the control cells, the cells positive for β-gal staining was significantly increased in AngII group, and showed cell cycle arrest at G(0)/G(1) phase with decreased S-phase cell percentage and cell viability. The expression levels of P53 and P16 were significantly increased in the cells with AngII exposure (P<0.05). LBP treatment of AngII-exposed cells resulted in decreased β-gal-positive cells with a reduction in G(0)/G(1) phase cells and an increase in S phase cells. LBP treatment also increased the cell viability and significantly decreased the expression levels of P53 and P16 (P<0.05).</p><p><b>CONCLUSION</b>LBP can delay AngII-induced aging of HUVECs possibly by down-regulating the expression of P53 and P15.</p>
