ObjectiveTo evaluate the effect of standardized blood pressure measurement in consulting room （SBPM） model on blood pressure screening of non-hypertensive patients in community. MethodsFour communities were randomly selected from Fengxian District of Shanghai， and non-hypertensive patients in the communities were included for screening. Based on the communities， participants were further classified into the intervention group and control group. A one-year intervention study was conducted from January 1， 2021 to December 31， 2021. The intervention group received the intervention measures of standardized measurement， and the control group remained the routine measurement. The distribution of blood pressure values and last digit of the values between the intervention group and control group were tested using Chi-square test and normality test. Then changes in abnormal blood pressure rate before and after the intervention were determined by double difference method. Statistical analysis was performed using SPSS 20.0. ResultsA total of 15 368 participants were included in the intervention group， and 19 811 participants in the control group. After the intervention， range of the last digit of blood pressure values in the intervention group was 9.55%‒10.41%， of which that of systolic and diastolic blood pressure were equally distributed （P=0.932 and 0.871， respectively）. The range of the last digit in the control group was 1.31%‒42.58%， of which that of systolic and diastolic blood pressure showed unequal distribution （P<0.001）. Through one-year standardized measurement intervention， the abnormal rate of blood pressure in the intervention group was 26.29%， which was 7.61 times as high as that in the control group （OR=7.55， 95%CI： 6.75‒8.57， P<0.001）. ConclusionStandardized blood pressure measurement in consulting room is suitable for the screening of blood pressure measurement in community， which has higher data quality than that of routine measurement.

Objective:To observe the effect of observing good swallowing on the swallowing action of stroke survivors with dysphagia.Methods:Eighteen stroke survivors with dysphagia were randomly divided into a treatment group ( n=9) and a control group ( n=9). In addition to routine swallowing rehabilitation therapy, the treatment group was asked to simulate swallowing after watching a video of normal people′s swallowing action. They did so 5 times a week for 10 minutes, while the control group just watched landscape videos at the same time. The treatment lasted 8 weeks. Before and after the treatment, both groups were assessed using the eating assessment tool (EAT-10), the functional oral intake scale (FOIS) and the penetration and aspiration scale (PAS). Functional magnetic resonance imaging (fMRI) was also used to observe their swallowing action. Results:There was no significant difference between the two groups in any of the measurements before the treatment. After the 8 weeks of treatment the average EAT-10, FOIS and PAS scores of the treatment group were all significantly better than before the treatment and better than the control group′s averages at the time. fMRI showed significantly more areas activated in the precuneus, parietal lobe, posterior central gyrus, BA7, BA5, frontal lobe and paracentral lobule in the treatment group compared with before the intervention and also more than in the control group.Conclusions:Observing proper swallowing action can improve dysphagia and activation of the swallowing-related brain areas of stroke survivors.

Objective:To observe the effect of applying repetitive transcranial magnetic stimulation (rTMS) on swallowing function and auditory evoked potentials in the brain-stems of stroke survivors with dysphagia.Methods:Sixty stroke survivors with dysphagia were randomly assigned to an observation group and a control group, each of 30. Both groups were given 30 minutes of routine swallowing training 6 times a week for 5 weeks, while the observation group was additionally provided with two-second bursts of rTMS on the left and right brain hemispheres alternately for 20 minutes daily. The frequency was 3.0Hz and the strength was 80% of the resting motor threshold (RMT), with an interval of 10 seconds between bursts. Before and after the treatment, both groups′ swallowing was assessed using the functional communication measure (FCM) and the modified Mann swallowing capacity evaluation scale (MMASA). Brainstem auditory evoked potentials (BAEP) were recorded to detect any changes in the peak latency (PL) and inter-peak latency (IPL). The clinical efficacy was also observed.Results:After the treatment, the average FCM results of both groups had improved significantly, but the observation group had improved significantly more. The average MMASA total scores and the average scores on all the sub-items had improved significantly more in the observation group except for the expressive speech disorder and anarthria scores. After the treatment, improvement was observed in respiration, anarthria, range of motion of the tongue muscles, strength of the tongue muscles, gag reflex and soft palate movement compared with before the intervention. Peak and inter-peak latencies had also improved significantly more in the observation than in the control group, on average.Conclusions:rTMS combined with conventional swallowing training can significantly improve the swallowing of dysphagic stroke survivors, and shorten the PL of the BAEP so as to better regulate deglutition.
