The present paper is to evaluate the scientific research level and development trends of biomedical engineering in China using metrology analysis on Chinese biomedical engineering scientific literatures. Pubmed is used to search the biomedical engineering publications in recent 5 years which are indexed by Science Citation Index, and the number and cited times of these publications and the impact factor of the journals are analyzed. The results show that comparing with the world, although the number of the publication in China has increased in recent 5 years, there is still much room for improvement. Among Chinese mainland, Hongkong and Taiwan, Chinese mainland maintains the obvious advantage in this subject, but Hongkong has the highest average cited number. Shanghai and Beijing have better research ability than other areas in Chinese mainland.
ObjectiveTo analyze the disease burden and evolving trends for gastric cancer in China and worldwide from 1990 to 2021. MethodsBased on the 2021 Global Burden of Disease (GBD) database, we analyzed the burden of gastric cancer using indicators such as incidence, mortality, disability-adjusted life years (DALYs), years of life lost (YLLs), and years lost due to disability (YLDs). Joinpoint regression analysis was used to calculate the average annual percentage change (AAPC) of these indicators to show trends over time. ResultsIn 2021, the standardized incidence rate of gastric cancer was 14.33 (per 100 000) worldwide and 29.05 (per 100 000) in China, with corresponding standardized mortality rates of 11.20 (per 100 000) and 21.51 (per 100 000). The standardized incidence rate of gastric cancer in China trended downward during 1990–2021 (AAPC=–1.61%, P<0.05), but was lower than the global decline (AAPC=–1.77%, P<0.05). During 1990-2021 in China, the rates of standardized DALYs (AAPC=–2.76%, P<0.05), standardized YLLs (AAPC=–2.78%, P<0.05) and standardized YLDs (AAPC= –1.25%, P<0.05) all showed a significant decrease. The global rates of standardized DALYs (AAPC=–2.42%, P<0.05), standardized YLLs (AAPC=–2.44%, P<0.05) and standardized YLDs (AAPC=–1.56%, P<0.05) all showed a significant decrease. These AAPC values above indicated a general attenuation in the gastric cancer burden across all age groups, both in China and worldwide. ConclusionsDespite these signs of a decline in disease burden indicators for gastric cancer in China and worldwide, the number of cases and deaths in gastric cancer remains substantial coupled with the heavy burden on the healthcare system. Therefore, increased efforts in early detection and prevention strategies are of utmost importance to further reduce the impact of this malignant disease.
Objective To analyze the trends in the burden of intracerebral hemorrhage (ICH) and its related risk factors in China from 1990 to 2021, providing evidence for targeted prevention and control. Methods Based on public data from the Global Burden of Disease Study 2021, four epidemiological indicators, including incidence, prevalence, deaths, and disability-adjusted life-years (DALYs) were selected to describe the burden of ICH in China in 2021. Change rates and estimated annual percentage changes (EAPC) were calculated to evaluate the trends in disease burden from 1990 to 2021. The Das Gupta method was used to decompose the effects of population growth, population aging and epidemiological changes on the burden during this period. Finally, the attributable burden of risk factors related to ICH was analyzed. Results In 2021, the age-standardized incidence, prevalence, mortality, and DALY rates of ICH in China were 61.2/100000, 222.1/100000, 68.8/100000, and 1351.6/100000, respectively, all higher than global estimates. From 1990 to 2021, although these rates showed a declining trend (EAPC: −2.24, −1.26, −2.38, and −2.47, respectively), the absolute disease burden, including the absolute number of incidence cases, prevalence cases, deaths, and DALYs, continued to rise, with an increase ranging from 20.57% to 51.59%. In addition, the burden of ICH in China varied by age and sex, with older adults and males experiencing a higher burden. Decomposition analysis indicated that population aging and growth were the primary drivers of the increasing ICH burden in China, while epidemiological changes mitigated this trend. Metabolic factors were the predominant attributable risk factors for ICH. High systolic blood pressure, ambient particulate matter pollution, and diet high in sodium were important risk factors common to both genders. The DALY burden attributable to smoking and alcohol use was higher in men, whereas impaired kidney function and secondhand smoke had a greater impact on women. Conclusions The burden of ICH in China has continued to increase from 1990 to 2021, and it may further escalate in the context of population aging. Risk factor control remains a key priority for prevention. Future strategies should incorporate age- and sex-specific interventions to reduce the ICH burden in China.
