Objective To investigate the impact on the endothelial cell function and renal blood flow through effective treatment for elderly patients with hypertension. Methods 64 cases of elderly hypertensive patients over 70years old with effective treatment, according to pre-treatment blood pressure, were divided into two groups: hyptension level-2 group(30cases) and hypertension level-3 group(34cases), and 30 cases of elderly people with health physical examination during the same period were setlected as the control group. Endothelial cell function was detected, including the endothelin-1 (ET-1)、 nitrous oxide (NO), thromboxane B2 (TXB2)、 6-keto-prostaglandinF1α (6-K-PDGF1α) in plasma. Renal blood flow was explored by color doppler ultrasonic instrument ,involving peak velocity in systole(PSV) and lowest velocity in end-diastole(EDV) of renal arteries, segmental arteries and interlobar arteries.After indicators had reached the standard 1 month in the hypertension level-2 and hypertension leve1-3 patients with effective antihypertensive therapy, the difference of ET-1, NO, TXB2,6-k-PGF1o and PSV, EDV among the three groups were compared. Results The differences were statistically significant in ET-1, NO, TXB2,6-k-PGF1α, PSV and EDV before treatment among three groups (P ＜ 0.05). After blood pressure treated had reached the standard 1 month,indicators were no statistically meaningful difference among the three groups (P ＞ 0.05). Conclusion After effective clinical treatments, the endothelial cell function and renal blood flow of the elderly hypertensive patients can be improved. At the same time, to delay renal damage in elderly patients with hypertension provide a theoretical basis.

Objective To explore the effect of oral sensorimotor therapy (OSMT), acupuncture, and low frequency electrical stimulation on salivation in patients with cerebral palsy. Methods From September, 2014 to October, 2015, 80 cerebral palsy patients with salivation were recruited. They were randomly divided into four treatment groups:group A was treated with OSMT, group B was treated with acupunc-ture, group C was treated with frequency electrical stimulation, and group D was treated with acupuncture and low frequency electrical stim-ulation, for eight weeks. Meanwhile, 20 cerebral palsy patients with salivation from outpatients were chosen as control group. Results There was no improvement in the root mean square (RMS) value of surface electromyography (sEMG) after treatment in both the control group and group A (t<1.668, P>0.05), and the RMS value significantly improved in the groups B, C and D (t>8.983, P<0.001). There was no sig-nificant difference in the salivation score and RMS value between the control group and group A (W=389.5, t=2.041, P>0.05), and they was better in the groups B, C and D than in the control group and group A (W>226.0, t>8.534, P<0.01), as well as in group D than in groups B and C (W>306.0, t>3.663, P<0.05). Conclusion Acupuncture and low frequency electrical stimulation could effectively improve salivation in children with cerebral palsy, and their combination was superior to either ones, while OSMT did not show obvious benefit.
