Objective:To investigate WS 582-2017 Specifications for testing of quality control in X and γ ray stereotactic radiotherapy system (hereinafter referred to as WS 582-2017) with respect to its current status, existing problems and evaluation since its implementation in Beijing, Chongqing, Jiangsu and Sichuan. Methods:The evaluation of this standard was carried out by means of field survey, questionnaire survey and expert seminar. In accordance with the WS 582-2017 implementation assessment programme, a total of 153 professionals involved in the implementation of WS 582-2017 from 80 radiological health technical service institutions, health supervision institutions and medical institutions of two municipalities and two provinces were surveyed in 2023. The investigation was carried out by using a combination of cluster sampling and stratified sampling and through sampling professionals with of different institution characteristics and different technical titles. The general survey method was used for Jiangsu province, while the cluster sampling method was used for others, with 153 individulas from 80 institutions being sampled for the investigation.Results:The awareness rate of WS 582-2017 was 80.39%, of which 90.85% considered it to be scientific and rigorous, 81.05% considered it to be operational and 97.39% considered it to be in consistency with the relevant regulatory standards, 90.20% considerd it to have played an important role in promoting radiological protection optimization for radiotherapy, 90.85% considered the implementation of it to have played a significant role in the quality control of standarded testing of radiotherapy equipment, and 86.93% considered the implementation of it to have played a significant role in enhancing the professional competence of relevant technicians.Conclusions:The overall implementation of WS 582-2017 in two municipalities and two provinces is good, with scientific and operable technical contents and the remarkable effect achieved in its implementation. However, the WS 582-2017 needs to be further improved in some areas, and training on the standard needs to be strengthened to improve the awareness rate of it.

Objective:To investigate the changes of cognitive function and self-care ability in patients with mild cognitive impairment after stroke after sensory integration therapy.Methods:One hundred patients with mild cognitive impairment after stroke were divided into control group and intervention group according to the random number table method. The control group was given the routine health education path and rehabilitation training, and the intervention group was given the cognitive rehabilitation through sensory integration therapy on the basis of the control group. The cognitive function and self-care ability of the patients were evaluated by the Montreal cognitive assessment(MoCA) and daily self-care ability scale(ADL) before and after intervention.Results:After intervention, the total MoCA score, visual space, nominalization, language, abstraction and memory scores of the intervention group were 26.02±1.15, 3.50±0.76, 2.98±0.14, 2.90±0.30, 2.84±0.37 and 3.18±0.69, respectively, while those of the control group were 23.32±1.90, 2.86±1.20, 2.78±0.42, 2.82±0.39, 1.58±0.54 and 2.82±0.94, respectively. The difference between the two groups was statistically significant ( t value was -18.296--2.064, all P<0.05). The scores of attention and directional force in the intervention group were 5.44±0.67 and 5.18±0.85, respectively, while those in the control group were 5.32±0.84 and 5.14±0.78, respectively. There was no statistically significant difference between the two groups ( t value was -1.288, -0.704, P>0.05).After intervention, the total ADL score, stool, urine, toilet, eating, dressing and bathing scores of the intervention group were 65.00±5.98, 5.90±2.19, 6.40±2.27, 7.40±2.72, 7.80±2.70, 7.50±2.53 and 5.50±1.52, respectively, The control group was 53.60±10.20, 3.50±3.23, 5.00±3.50, 5.50±3.23, 5.40±3.76, 5.90±3.45, and 4.40±2.79, respectively. The difference between the two groups was statistically significant ( t value was -7.573~-2.615, all P<0.05). Conclusions:Sensory integration therapy can improve the cognitive function and self-care ability of patients with mild cognitive impairment after stroke.

Objective: To analyze the effects of green aerobics on serum homocysteine concentration and the morning surge in blood pressure in H-type hypertension patients with ischemic stroke. Methods: The 125 patients who suffer from H-type hypertension as well as ischemic stroke were divided into two groups by random digital table method. The control group (60 cases) accepted neurology normal nursing, while the intervention group (65 cases) accepted green aerobics intervention except the neurology normal nursing. The patients′ homocysteine level and the morning surge in blood pressure were assessed in two groups. Results: Two weeks later, the homocysteine level in the control group was (9.44±2.07) mmol/L, while the intervention group was (11.62±3.03) mmol/L. The difference between the two groups had statistics significance(t=-5.257, P <0.05). The morning surge in blood pressure was (18.75±7.51) mmHg(1 mmHg=0.133 kPa), while the control group was (34.07±2.91) mmHg. The difference between the two groups had statistics significance (t=15.761, P <0.05). Conclusions The green aerobics could effectively lower the homocysteine level and the morning surge in blood pressure of patients who suffer from H-type hypertension as well as ischemic stroke. It was an alternative therapy or assistant therapy without side effects.

Objective The present study aimed to evaluate the effects of isometric resistance training(IRT)conducted using handgrip exercise on blood pressure variability (BPV) and heart rate variability (HRV) in hypertensive patients with minor ischemic stroke (MIS).Methods One hundred and twenty-five hypertensive patients with MIS were included in the present study. Patients were randomized into two groups with random number table. Patients in the control group (n=60) were nursed in the routine care in department of neurology, while patients in the experimental group (n=65) received the IRT.The 24-hour ambulatory blood pressure-monitoring assessment was performed using validated oscillometric recorders (A&D TM- 2430, A&D Inc.,Tokyo,Japan).The 24- hour ambulatory electrocardiography measurement was performed using electrocardiocorder(PI200A-A, QunTian Inc.,Shanghai,China).The BPV ratio and the HRV ratio were assessed in the two groups. Results 24 hours after the intervention, intervention group 24 hours systolic blood pressure variation coefficient and diastolic blood pressure variation coefficient were(10.16 ± 1.95)％,(12.6 ± 7.15)％,the control group, respectively (12.92 ± 2.79)％, (17.38±4.49)％, two groups compare the difference was statistically significant (t=6.450, 4.435, P<0.05). Intervention group of normal sinus R- R period between the standard deviation, to the phase difference between adjacent R- R , root mean square value of the whole difference in more than 50 ms continuous period of percentage between normal R-R and triangle Index were (173.3±58.5) ms, (115.9±74.4), (54.8± 24.1)％, (53.3 ± 15.1).The control group was(128.7 ± 40.2)ms, (82.1 ± 35.2),(39.9 ± 17.1)％, (30.6 ± 14.9), and the difference between the two groups was statistically significant(t=-8.439--3.207, all P<0.05). Conclusions Isometric resistance training conducted using handgrip exercise could increase the HRV and decrease the BPV in hypertensive patients with MIS. These results indicated that the IRT may improve the life quality of hypertensive patients with MIS.
