Objective:To present the epidemiological characteristics of ≤28 days case fatality in both hemorrhagic stroke (HS) and ischemic stroke (IS) patients in national cardiovascular disease surveillance areas from 2015 to 2019.Methods:Data on all new patients with stroke and ≤28 days outcomes from 2015 to 2019 were from the China Registry of Cardiovascular Events, which was established in 2014, covering 100 counties (cities, districts) in 31 provinces in China. Poisson regression was used to analyze the annual trend of ≤28 days case fatality. The age-standardized case fatality was directly calculated based on all new stroke onset.Results:In total, 112 069 deaths in HS patients ≤28 days after the onset, as well as 94 373 in IS patients, were identified during the study period. In 2019, the ≤28 days case fatality rate in HS patients was 4.75 times that of IS patients (37.08% vs. 7.80%), as well as that 4.06 times in urban areas (30.13% vs. 7.43%) and 5.30 times in rural areas (42.63% vs. 8.05%), respectively. Thus, in rural areas, HS patients showed 41.49% higher ≤28 days case fatality rate than that in urban areas, as well as 8.34% higher in IS patients. Those ≤28 days case fatality in both stroke subtypes onset increased with age and reached the highest level in those aged 85 years and over. During the study period, HS and IS patients in each age group displayed significant decrease trend in ≤28 days case fatality rate (trend P<0.001). Compared with that in 2015, the age-standardized ≤28 days case-fatality in HS patients in 2019 decreased by 28.52%, which was more in urban areas (-34.27%) than that in rural areas (-23.19%). Meanwhile, IS patients experienced a 39.90% reduction in ≤28 days case fatality, which was much lower in urban areas (-31.62%) than in rural areas (-45.10%, all trend P<0.001). Conclusions:From 2015 to 2019, ≤28 days case fatality in both HS and IS patients decreased in China. Wide variations of ≤28 days case-fatality were evident in the level and trend in stroke subtype, age of patients, as well as urban and rural areas. More precise and comprehensive strategies for stroke prevention, treatment, and post-stroke management are urgently required in China.

Objective:To analyze the characteristics and changes in incidence and mortality of ischemic and hemorrhagic stroke among Chinese residents from 2015 to 2019.Methods:The incidence and mortality data of ischemic and hemorrhagic stroke from 2015 to 2019 were collected from the China Registry of Cardiovascular Events (China RACE), which was established in 2014 and covered 100 counties (cities and districts) in 31 provinces in China. The age-standardized incidence rate (ASIR) was calculated using the Seventh National Census data as the standard population. The ratio of the incidence rate of ischemic stroke to hemorrhagic stroke was calculated. The subtype-specific mortality-to-incidence ratio (M/I) was calculated by the ratio of the number of deaths to the reported incidence cases. The relative ratio (RR) of M/I for ischemic to hemorrhagic stroke was calculated. The Joinpoint model was used to analyze the annual percentage change (APC) and trend of the incidence rate of stroke.Results:From 2015 to 2019, a total of 1 354 614 new stroke cases were reported, including 1 077 244 (79.52%) ischemic stroke and 277 370 (20.48%) hemorrhagic stroke cases, respectively. A total of 248 620 stroke deaths were reported, including 119 819 (48.19%) ischemic stroke deaths and 128 801 (51.81%) hemorrhagic stroke deaths. The incidence ratio of ischemic/hemorrhagic stroke from 2015 to 2019 was 3.50∶1, 3.76∶1, 3.63∶1, 4.23∶1, and 4.35∶1, respectively. From 2015 to 2019, there was no statistically significant annual trend of ASIR of ischemic stroke in overall, urban and rural areas and males ( Ptrend>0.05), while there was a downward trend in females (APC=-1.02%, Ptrend=0.042). The incidence of hemorrhagic stroke in the whole population, rural areas, males and females showed a downward trend ( Ptrend<0.05). Patients aged 45-49 years had an upward trend in the incidence rate of ischemic stroke (APC=3.82%, Ptrend=0.011), while those aged 70-74 years (APC=-7.37%, Ptrend=0.034), 80-84 years (APC=-9.75%, Ptrend=0.001) and 85 years and over (APC=-11.22%, Ptrend=0.017) presented a downward trend in the incidence of hemorrhagic stroke. During the period, the overall relative ratio of M/I (RR) for ischemic to hemorrhagic stroke was 4.2∶1, which was lower in urban than in rural areas (3.8 vs. 4.3). The largest gap between urban and rural areas was in the 55-59 age group (6.8 vs. 9.3). Conclusion:The incidence and mortality of ischemic and hemorrhagic stroke among Chinese residents are severe from 2015 to 2019, and there are regional and population differences.

Objective:To study the laryngeal functional characteristics of patients with amyotrophic lateral sclerosis (ALS)disease diagnosed at the voice clinic.Methods:A retrospective analysis(case series study) was conducted on the laryngeal functional characteristics of 7 patients [2 males, 5 females, age ranged from 43 to 76(60.85±13.18)]with motor neuron disease who visited the voice clinic and were ultimately diagnosed by neurologists. The data included laryngostroboscopy, fiberoptic endoscopic examination of swallowing(FEES), acoustic analysis and laryngeal electromyography(LEMG). Descriptive methods were used for analysis.Results:①There were 2 males and 5 females, with an average age of (60.85±13.18) years. They had previously visited the otolaryngology department more than twice, visit frequency with an average of 3.57 and an average diagnosis time of 12.28 months. The main complaints of the patient at the time of treatment were voice change, dysphagia or vocal fatigue. ②LEMG: Among 7 cases, 4 cases demonstrated neurogenic damage, all of which were bilateral, and 3 cases showed normal findings on examination. Spontaneous potentials (SP) were present in three cases for more than 6 months, with the longest duration being 24 months. Three cases exhibited the coexistence of spontaneous potential and reinnervated motor unit potentials (MUPs), and two cases showed bundle tremor potential.③Laryngostroboscopy revealed bilateral vocal fold asymmetry and glottic insufficiency in 7 cases, and decreased vocal cord movement in 4 cases, and vocal cord atrophy in 5 cases. FEES showed that 7 patients presented with mild to severe swallowing dysfunction, 3 cases had soft palate insufficiency and mild to severe food residues in the epiglottic valley and pyriform fossa. 1 case showed leakage and 1 case showed aspiration.Conclusions:Patients presenting with initial symptoms of abnormal laryngeal function should be vigilant for the possibility of motor neuron disease, especially when laryngostroboscopy reveals abnormal vocal fold movement and swallowing dysfunction. LEMG examination reveals bilateral neurogenic damage, prolonged spontaneous potential, coexistence of spontaneous potential and reinnervated MUPs, and the appearance of bundle tremor potential, which is beneficial for early detection of motor neuron disease.

Objective:To assess the trends in case-fatality rates for acute myocardial infarction (AMI) in China from 2015 to 2019.Methods:This study employed a population-based surveillance. Data from the China Registry of Acute Cardiovascular Event (China RACE) were utilized, including AMI cases reported by Grade Ⅱ and Grade Ⅲ hospitals at the disease surveillance sites across China from January 1 st 2015 to December 31 st 2019. The 28-day mortality outcome for reported AMI events was obtained by linking to the national death certificate registry system. The study analyzed the overall and age-standardized case-fatality rates, as well as their annual percent change (APC), during the study period, stratified by gender, age, and region. Results:The overall 28-day case fatality rate for AMI was 28.97% (22 532/77 764) from 2015 to 2019. The age-standardized case-fatality rate for AMI declined significantly from 37.53% in 2015 to 18.58% in 2019, with an APC of -14.33% ( P=0.018). We observed a significant downward trend in case-fatality rates of AMI in both genders (both P<0.05). Among males, the case-fatality rate decreased more steeply in younger males compared to elder counterparts. The most marked decreases were seen in males aged<35 years and 35 to 44 years, with APC of -27.63% ( P=0.007) and -22.65% ( P=0.004), respectively. In females, we observed a relatively stable decrease in case-fatality across age groups. The age-standardized case-fatality rate of AMI in eastern and central China decreased significantly from 2015 to 2019, with the APC of -19.22% ( P=0.006) and -15.62% ( P=0.032) respectively. However, the age-standardized case-fatality rate of AMI in western China remained stable ( P=0.227). Conclusions:The prognosis of AMI has considerably improved from 2015 to 2019 in China, regardless of ages and gender. Inequality in case-fatality rates among geographic regions highlights the need for targeted strategies in AMI prevention in western regions.

OBJECTIVETo explore the knowledge, attitude and behavior of salt reduction among Chinese adults aged over 18 years old in 2010.
METHODSA total of 96 916 adults aged over 18 were recruited from 162 surveillance points in 2010, applying multi-stage stratified cluster random sampling method.Information about subjects salt reduction related knowledge, attitude and behavior were collected by face-to-face interview. After performing complex weighted analysis, the awareness, willingness and behavior rates were compared by different genders, age groups, urban, rural and different regions.
RESULTSThe unweighted salt reduction rate of the awareness, willingness and behavior among Chinese adults were 63.0%, 84.5% and 44.5%. After being weighted, the awareness rate was 62.9%, the awareness rate difference was not significant between males (62.4%) and females (63.4%) (χ(2) = 1.66, P > 0.05), but the urban areas (77.1%) were significantly higher than the rural areas (56.3%) (χ(2) = 85.11, P < 0.01) . The difference among different ages was significant (χ(2) = 228.68, P < 0.01) with descending order in 18-44, 45-59 and ≥ 60 years old (67.8%, 59.8%, 50.1%, respectively). The difference among different regions was not significant (χ(2) = 9.82, P < 0.01) in eastern, central and western China (68.2%, 61.3%, 57.1%, respectively). After being weighted, the willingness rate was 83.8%, the willingness rate in females (85.8%) was significantly higher than that in males (81.9%) (χ(2) = 61.92, P < 0.01) , and the urban areas (87.1%) were significantly higher than the rural areas (82.3%) (χ(2) = 15.49, P < 0.01) . The difference among different ages was significant (χ(2) = 74.50, P < 0.01) with descending order in 18-44, 45-59 and ≥ 60 years old (85.3%, 83.1%, 79.6%, respectively). The difference was not significant (χ(2) = 0.58, P > 0.05) among eastern, central and western China (84.3%, 84.0%, 82.9%, respectively). After being weighted, the behavior rate of salt reduction was 42.2%, the behavior rate in females (45.6%) was significantly higher than that in males (38.8%) (χ(2) = 107.74, P < 0.01), and urban areas (56.5%) were significantly higher than the rural areas (35.6%) (χ(2) = 74.38, P < 0.01) . The difference was not significant (χ(2) = 4.19, P > 0.05) among 18-44, 45-59 and ≥ 60 years old(41.5%, 43.6%, 42.2%, respectively). The behavior rate of salt reduction difference in eastern China(47.8%) was significantly higher than that in central (38.9%) and western (38.0%) (χ(2) = 7.22, P < 0.05).
CONCLUSIONSThe rate of willingness to reduce salt is higher, but the awareness rate and the behavior rate of salt reduction are not high, especially among the population who are from rural area, or who are from central and western China.
