BACKGROUND:
Death burden of stroke is severe with over one-third rural residents in China, but there is still a lack of specific national and high-quality reports on the urban-rural differences in stroke burden, especially for subtypes. We aimed to update the understanding of urban-rural differences in stroke deaths.
METHODS:
This is a descriptive observational study. Data from the national mortality surveillance system, which covers 323.8 million with 605 disease surveillance points (DSPs) across all 31 provinces, municipalities, and autonomous regions in China. All deaths from stroke as the underlying cause from 2015 to 2020 according to DSPs. Crude mortality rate and age-standardized mortality rate (ASMR) were estimated through DSPs. Average annual percentage change was used to explain the change in mortality rate.
RESULTS:
From 2015 to 2020, the majority of deaths from all stroke subtypes occurred in rural areas. There were significant differences between the changes of urban and rural ASMRs. On the whole, the changes in urban areas were evidently better, and the ASMR differences were basically expanding. Stroke ASMR in urban China decreased by 15.5%. The rural ASMR of ischemic stroke increased by 12.9%. The rural and urban ASMRs of intracerebral hemorrhage decreased by 24.9% and 27.4%, and those of subarachnoid hemorrhage decreased by 29.5% and 40.4%, respectively. The highest ASMRs of all stroke subtypes and the increasing trend of ischemic stroke ASMR make rural males the focus of stroke management.
CONCLUSIONS
The death burden of stroke varies greatly between urban and rural China. Rural residents face unique challenges.

The lumbar intervertebral disc exhibits a complex physiological structure with interactions between various segments, and its components are extremely complex. The material properties of different components in the lumbar intervertebral disc, especially the water content (undergoing dynamic change as influenced by age, degeneration, mechanical loading, and proteoglycan content) - critically determine its mechanical properties. When the lumbar intervertebral disc is under continuous pressure, water seeps out, and after the pressure is removed, water re-infiltrates. This dynamic fluid exchange process directly affects the mechanical properties of the lumbar intervertebral disc, while previous isotropic modeling methods have been unable to accurately reflect such solid-liquid phase behaviors. To explore the load-bearing mechanism of the lumbar intervertebral disc and establish a more realistic mechanical model of the lumbar intervertebral disc, this study developed a solid-liquid biphasic, fiber-reinforced finite element model. This model was used to simulate the four movements of the human lumbar spine in daily life, namely flexion, extension, axial rotation, and lateral bending. The fluid pressure, effective solid stress, and liquid pressure-bearing ratio of the annulus fibrosus and nucleus pulposus of different lumbar intervertebral discs were compared and analyzed under the movements. Under all the movements, the fluid pressure distribution was closer to the nucleus pulposus, while the effective solid stress distribution was more concentrated in the outer annulus fibrosus. In terms of fluid pressure, the maximum fluid pressure of the lumbar intervertebral disc during lateral bending was 1.95 MPa, significantly higher than the maximum fluid pressure under other movements. Meanwhile, the maximum effective solid stress of the lumbar intervertebral disc during flexion was 2.43 MPa, markedly higher than the maximum effective solid stress under other movements. Overall, the liquid pressure-bearing ratio under axial rotation was smaller than that under other movements. Based on the solid-liquid biphasic modeling method, this study more accurately revealed the dominant role of the liquid phase in the daily load-bearing process of the lumbar intervertebral disc and the solid-phase mechanical mechanism of the annulus fibrosus load-bearing, and more effectively predicted the solid-liquid phase co-load-bearing mechanism of the lumbar intervertebral disc in daily life.

Objective:To learn about the epidemiological and clinical characteristics of children with brucellosis, in order to provide reference for clinical diagnosis and treatment of brucellosis in children.Methods:Clinical data of children with brucellosis (aged ≤14 years) who visited the Department of Infectious Diseases at Beidahuang Industry Group General Hospital from December 2020 to December 2022 were retrospectively collected, and their epidemiological characteristics, clinical characteristics, laboratory tests, treatment and outcome were summarized and analyzed.Results:A total of 34 children with brucellosis were included, including 25 males (73.53%) and 9 females (26.47%), with a gender ratio of 2.78 ∶ 1.00. The median age was 8 years and 1 month, mainly in the age group of 6 to 14 years (19 cases, 55.88%). Epidemiological investigation showed that most of the affected children were rural residents (25 cases, 73.53%), with more contact with cattle/sheep (26 cases, 76.47%). The onset time was mainly concentrated in summer (15 cases, 44.12%) and spring (13 cases, 38.24%). The clinical symptoms were mainly fever (97.06%, 33/34) and arthralgia (64.71%, 22/34). In the laboratory tests, 25 cases (73.53%) had positive blood cultures, and the white blood cell count (WBC) of 30 cases (88.24%) was (4 - 10) × 10 9/L. Among the abnormalities of liver function, aspartate aminotransferase (AST) increased in 19 cases (55.88%), alanine aminotransferase (ALT) increased in 14 cases (41.18%) and γ-glutamyl transpeptidase (GGT) increased in 6 cases (17.65%). Among the myocardial enzymatic abnormalities, α-hydroxybutyrate dehydrogenase (HBDH) increased in 29 cases (85.29%), lactate dehydrogenase (LDH) increased in 27 cases (79.41%), and creatine kinase isoenzyme (CK-MB) increased in 8 cases (23.53%). After treatment, 25 children with positive blood culture turned negative. Conclusions:Children with brucellosis are mainly male, older and rural residents. The clinical manifestations are mainly fever and arthralgia. Doctors in relevant departments should conduct detailed epidemiological investigations and laboratory tests for such children in clinical work, in order to achieve early detection, diagnosis and treatment of pediatric brucellosis.

Objective:To investigate the status of nursing practice and organizational management for reperfusion therapy in ischemic stroke across medical institutions in Beijing.Methods:In June 2023, a survey was conducted among nursing managers from 62 medical institutions under the jurisdiction of the Beijing Stroke Treatment Quality Control and Improvement Center. The survey aimed to assess the current nursing practices and organizational management for reperfusion therapy in ischemic stroke.Results:Among the 62 medical institutions, 16.13% (10/62) had dedicated reperfusion therapy nurses for stroke, and 87.10% (54/62) had established specific nursing protocols and procedures for stroke reperfusion therapy within their departments. However, 27.42% (17/62) of these institutions based the development and updates of their protocols on experiential summaries rather than standardized guidelines. In terms of nursing practice, there was room for improvement in emergency identification and triage of suspected stroke patients, assistance with intravenous thrombolysis, patient condition monitoring, early rehabilitation, and related health education. Regarding nursing quality control, significant differences were observed between institutions that regularly conducted quality control of stroke reperfusion therapy nursing and those that organized regular training sessions for nurses in this area ( P<0.05) . Conclusions:While nursing practices and quality for stroke reperfusion therapy in Beijing are progressing, there are disparities in regional development. There is a high demand for specialized stroke nursing and targeted technical training.
