Objective To investigate the application effect of acupoint massage combined with swallowing rehabilitation training in the rehabilitation of patients with swallowing dysfunction after stroke. Methods A total of 102 patients with swallowing dysfunction after stroke admitted to Zhengzhou People's Hospital from June 2021 to January 2023 were divided into the control group and the observation group by random number table method. The patients in the control group were treated with swallowing rehabilitation training, and the patients in the observation group were treated with acupoint massage on the basis of the control group. The rehabilitation effect, complications during treatment, swallowing function and hyoid-laryngeal complex mobility before and after treatment were compared between the two groups. Results The total effective rate of rehabilitation in the observation group [98.04% (50/51)] was higher than that in the control group [80.39% (41/51)], the difference was statistically significant (P<0.05). After four weeks of treatment, the clinical examination score, three times of five ml. warm water swallowing test, 60 mL warm water swallowing test and the total score of the standardized swallowing assessment (SSA) in the observation group were lower than those in the control group. The distances of hyoid bone forward, hyoid bone upward thyroid cartilage for- ward and thyroid cartilage upward were higher than those in the control group. and the differences were statistically significant (P<0.05). During the treatment, the incidence of complications in the observation group [3.92%(2/51)] was lower than that in the control group [17.65% (9/51)], and the difference was statistically significant(P<0.05). Conclusion The application of acupoint massage combined with swallowing rehabilitation training in the rehabilitation of patients with swallowing dysfunction after stroke has a significant effect. which can significantly improve the swallowing function and mobility of hyoid-laryngeal complex, and the incidence of complications is low.

Flotation tests were conducted on a gold ore in Gansu Province. The experiment used sodium carbonate as the regulator, copper sulfate as the activator, a mixture of butyl xanthate and dibutyl dithiophosphate as the collector, and No. 2 oil as the frother. Through twice roughing, twice scavenging, and three times cleaning in closed-circuit tests, a concentrate product with a gold grade of 251. 27 g/t and a gold recovery rate of 96. 67 % was obtained. The technical indicators are excellent, providing a technical basis for the separation of this type of gold ore. [ABSTRACT FROM AUTHOR]

The shear strength parameters of rock discontinuities have variability is a common sense and the shear strength variability is difficult to obtained due to the cost of direct shear tests. It is one of the main reasons restricting the development of rock slope reliability evaluation. In view of this, combined with a small number of measured rock discontinuities roughness curve samples, rock mechanical parameters, the JRC-JCS( joint roughness coefficient-joint compressive strength) shear strength model, random field theory and non-invasive discrete element numerical experiments, a method to obtain the variability index of rock discontinuities shear strength parameters was proposed. Applying this method to the reliability evaluation of a rock slope at the entrance section of a tunnel, The result show these as follows. The variance of the ordinate roughness of the main control rock discontinuities of the rock slope is 0. 012 5 cm 2, the correlation distance is 0. 75 cm, and the generated random roughness curve is similar to the measured sample. The average cohesion and internal friction angle of the rock discontinuities are 0. 427 MPa and 54. 9°, the standard deviations are 0. 229 MPa and 4. 47°, and the coefficients of variation are 53. 63% and 8. 14%, respectively. The slope stability coefficient obeys the normal distribution, the instability probability is 2. 8%, and the reliability is 1. 52. [ABSTRACT FROM AUTHOR]

Objective：To explore the synchronization effect of whole-body vibration therapy combined with squat-up training on ambulation of patients with stroke. Method：40 stroke survivors who could walk independently with supervision or assistive devices, were recruited from the Department of Rehabilitation Medicine, Huashan Hospital Affiliated to Fudan University (Pudong Campus) and were randomly divided into the WBVT group and the control group. Both groups received conventional rehabilitation treatment for 40 minutes per day. The WBVT group was given additional whole-body vibration therapy while squat-up training for another 20 minutes a day. The control group added sham stimulation of standing on the vibration platform with no vibration for the same amount of time per day. At the beginning of enrollment and after 4 weeks intervention, participants received two times evaluation by the wearable three-dimensional gait assessment instrument for the function of walking, and the electromyographic signals of the rectus femoris and long head of the biceps femoris were collected by surface electromyography instrument and statistical analysis on the data before and after the intervention. Result：After 4 weeks intervention, the stride speed and stride length of both groups improved siginificanlty (P<0.05), while the WBVT group was better than the control group (P<0.05). The swing angle of knee (flexion or extention)in the WBVT group improved significantly after intervention compared with the control group. At the single leg support phase (SS) of affected side, the differences were found in the synergistic contraction rate of the rectus femoris and biceps femoris in the bilateral lower extremity of the WBVT group after the intervention (P<0.05). At the swing phase (SW) of affected side, the differences were found in the synergistic contraction rate of the rectus femoris and biceps femoris in the bilateral lower extremity between the two groups before and after the intervention (P<0.05), but the affected side of the WBVT group was better than that the control group after intervention (P<0.05). Conclusion：Whole-body vibration therapy combined with rhythmic squat-up synchronous training can improve the stride speed, stride length and synergistic contraction rate of lower limb muscles for better ambulation of patients with stroke.
