BACKGROUND: The epidemiological pattern and disease burden of type 2 diabetes have been shifting in China over the past decades. This analysis described the epidemiological transition of type 2 diabetes in the past three decades and projected the trend in the future three decades in China. METHODS: Age-, sex-, and year-specific incidence, prevalence, death, and disability-adjusted life years (DALYs) for people with 15 years or older and diabetes or high fasting glucose in China and related countries from 1990 to 2021 were obtained from the Global Burden of Disease. We obtained the trends of age-, sex-, and year-specific rates and absolute numbers of incidence, prevalence, deaths, and DALYs attributable to type 2 diabetes in China from 1990 to 2021. Using the Lee-Carter model, we projected the incidence, prevalence, death, and DALYs attributable to type 2 diabetes to 2050 stratified by age and sex. RESULTS: The age-standardized incidence of type 2 diabetes was 341.5 per 100,000 persons (1.6 times in 1990) and the age-standardized prevalence was 9.96% (9960.0 per 100,000 persons, 2.5 times in 1990) in China 2021. In 2021, there were 0.9 million deaths and 26.8 million DALYs due to type 2 diabetes or hyperglycemia, as 2.9 and 2.7 times the data in 1990, respectively. The age-standardized rates of type 2 diabetes and hyperglycemia were projected to raise to 449.5 per 100,000 persons for incidence, 18.17% for prevalence, 244.6 per 100,000 persons for death, and 4720.2 per 100,000 persons for DALYs by 2050. The incidence of type 2 diabetes kept growing among individuals under the age of 20 years in the past three decades (128.7 per 100,000 persons in 1990 and 439.9 per 100,000 persons in 2021) and estimating 1870.8 per 100,000 in 2050. CONCLUSIONS The incidence, prevalence, and disease burden of type 2 diabetes grew rapidly in China in the past three decades. The prevention of type 2 diabetes in young people and the care for elder adults will be the greatest challenge for the country.

Objective:To evaluate the application value of artificial intelligence (AI) and robot of stereotactic surgery (ROSS)-assisted ultra-early thalamic hematoma drainage in elderly patients with minor thalamus and internal capsule hematoma (TICH) and severe hypoperfusion in the internal capsule area.Methods:A retrospective cross-sectional study was performed; 278 patients with TICH and severe hypoperfusion in the internal capsule area identified by AI medical imaging diagnostic system were enrolled from Department of Neurosurgery, Xingtai Central Hospital from January 2023 to August 2024. Among them, 134 patients (study group) received AI and ROSS-assisted ultra-early thalamic hematoma drainage, and 144 patients (control group) received drug treatment. Differences in baseline data and therapy efficiency between the two groups of patients were compared. Multivariate Logistic regression analysis was used to screen the independent influencing factors for prognosis in the study group 180 days after onset (good prognosis: modified Rankin scale scores of 0-3).Results:Compared with the control group, the study group had significantly higher Glasgow coma scale (GCS) score and regional cerebral blood flow (rCBF) in the internal capsule area 14 days after onset, and statistically higher therapy efficiency and good prognosis rate 180 days after onset ( P<0.05). In the study group, 84 patients had a good prognosis and 50 had a poor prognosis 180 days after onset; compared with the good prognosis group, the poor prognosis group had significantly higher proportion of patients with hyper-homocysteinemia history, lower GCS score on admission, larger volume of thalamic hematoma, higher proportions of patients with combined intraventricular hemorrhage and shunt-dependent hydrocephalus, and lower rCBF in the internal capsule area on admission ( P<0.05). Multivariate Logistic regression analysis showed that thalamic hematoma volume ( OR=2.527, 95% CI: 1.504-4.247, P<0.001), combined intraventricular hemorrhage ( OR=2.325, 95% CI: 1.460-3.703, P<0.001), shunt dependent hydrocephalus ( OR=2.371, 95% CI: 1.267-4.078, P=0.006), and rCBF in the internal capsule area on admission ( OR=0.672, 95% CI: 0.314-1.025, P<0.001) were independent risk factors for prognosis of patients in the study group. Conclusion:AI and ROSS-assisted ultra-early thalamic hematoma drainage is effective for elderly patients with minor TICH and severe hypoperfusion in the internal capsule area; patients with large thalamic hematoma volume, combined intraventricular hemorrhage, shunt-dependent hydrocephalus, and low rCBF in the internal capsule area on admission are prone to have a poor prognosis.

Objective:To reveal the coupling mechanism of beam temporal profile and tissue oxygen content on radical kinetics, further explain the potential biological basis of the FLASH effect, and provide a reference for beam optimization and treatment planning design of FLASH radiotherapy (FLASH-RT).Methods:TOPAS-nBio v3.0 was used to simulate the physical and chemical processes of electron beams in water, and a full-scale kinetic model was established covering the generation, diffusion, reaction, and quenching of free radicals such as hydroxyl radical (·OH) and hydrated electrons (e aq-). Under different beam temporal profiles (single pulse, multi-pulses, continuous wave irradiation) and different oxygen concentration conditions, the evolution dynamics of free radicals were systematically simulated. At the same time, the data on e aq- content were obtained by experimental measurement of laser absorption spectroscopy to verify the accuracy of the model prediction. Results:The changing trend of e aq- concentration measured in the experiment was highly consistent with the simulation result, verifying the reliability of the constructed model. The beam time structure had a significant impact on the peak value and duration of free radical concentration. The single-pulse structure can cause the free radicals to rapidly increase and then quickly quench in a short time, while the continuous or long-pulse structure can cause the radical concentration to remain at a high level for a long time. The evolution of ·OH was not sensitive to the oxygen environment, while e aq- are greatly affected by the oxygen environment. The scavenging efficiency of free radicals in a hypoxic environment was significantly decreased, leading to an enhanced accumulation of oxidative damage to biological macromolecules. The lifespan of e aq- in an oxygen-rich environment decreased rapidly. Conclusions:Radical kinetics are regulated by both the beam temporal profile and oxygen content. FLASH-RT can utilize single-pulse or multi-pulses intervals to form periodic windows, reducing normal tissue damage by efficiently scavenging free radicals through antioxidants, while free radicals in tumor tissues continuously accumulate and amplify damage, thus generating a selective protective effect.

Objective:To investigate the clinical value of a fully autonomous ultrasound robot in splenic ultrasound imaging.Methods:A retrospective study was conducted by enrolling 56 adult volunteers from the Third Medical Center of the Chinese PLA General Hospital between February 1-8，2024 as research subjects.A senior physician sequentially performed splenic ultrasound examinations using both the fully autonomous ultrasound robot and a matched portable ultrasound device. The acquired images were randomly coded and scored via a double-blind method by 3 physicians. The differences of the image quality scores and high-quality image proportions between the two groups were compared. Examination durations were recorded and compared between the two groups.Results:Both modalities successfully acquired splenic images in all 56 volunteers. No statistically significant differences were observed in image quality scores among the 3 physicians：（3.52 ± 1.31）points vs.（3.83 ± 1.23）points，（2.77 ± 1.23）points vs.（3.17 ± 1.17）points，and（3.48 ± 0.97）points vs.（3.79 ± 0.94）points（all P>0.05）. The numbers of images scoring ≥ 3 points showed no significant differences：45（80.36%） vs. 50（89.29%），30（53.57%） vs. 38（67.86%），and 48（85.71%） vs. 52（92.86%）（all P>0.05）. The fully autonomous ultrasound robot required significantly longer examination time［（60.86 ± 50.55）s vs.（7.95 ± 4.35）s， t=6.88， P＜0.01］. Conclusions:The fully autonomous ultrasound robot demonstrates comparable image quality and clinically acceptable image proportions to conventional portable ultrasound in splenic examinations. These findings suggest its potential equivalence to operator-dependent ultrasound for splenic imaging，supporting its feasibility as an alternative ultrasound modality despite longer procedural duration.
