Objective: To investigate the trends in incidence and mortality of stroke in Ningbo City, Zhejiang Province from 2012 to 2021, so as to provide the evidence for improving the stroke control strategy in Ningbo City. Methods: Data pertaining to the stroke incidence and mortality in Ningbo City from 2012 to 2021 were captured from Ningbo Municipal Chronic Disease Collaborative Management System, and the incidence and mortality of stroke was estimated and standardized by the Sixth National Population Census in 2010. The trends in incidence and mortality of stroke were evaluated using annual percent change (APC) in Ningbo City from 2012 to 2021. Results: A total of 185 747 residents with stroke were reported in Ningbo City from 2012 to 2021. The crude incidence of stroke was 312.78/105 in Ningbo City from 2012 to 2021, which appeared a tendency towards a rise (APC=2.429%, t=5.507, P<0.001), and the standardized incidence of stroke was 188.86/105, with no remarkable changes seen (APC=-0.399%, t=-1.544, P=0.161). There were 47 355 deaths due to stroke in Ningbo City from 2012 to 2021, and the crude and standardized mortality rates were 79.74/105 and 42.79/105, which both appeared a tendency towards a decline (APC=-4.778%, t=-6.867, P<0.001; APC=-8.269%, t=-13.729, P<0.001). Higher standardized incidence and mortality were seen among men (226.05/105 and 50.14/105) than among women (153.37/105 and 35.89/105), and the crude incidence and mortality of stroke appeared a tendency towards a rise with age (χ2trend=3 671.325, 1 419.107, both P<0.001). The standardized incidence and mortality of hemorrhagic stroke were 40.38/105 and 18.56/105, both showing a tendency towards a decline (APC=-5.042%, t=-12.958, P<0.001; APC=-11.570%, t=-14.979, P<0.001), and the standardized incidence of ischemic stroke was 143.91/105, appearing a tendency towards a rise (APC=1.254%, t=3.223, P=0.012), while the standardized mortality of ischemic stroke was 19.65/105, with no obvious changes seen (APC=-2.110%, t=-2.150, P=0.064). Conclusions The incidence of stroke appeared a tendency towards a rise and the mortality appeared a tendency towards a decline in Ningbo City from 2012 to 2021. Men and the elderly are at high risk of stroke.

The design of a conventional radiotherapy plan is a time-consuming and labor-intensive process, and relevant parameters need to be continuously adjusted in the plan optimization to identify the optimal plan. In addition, experience differences between planners, time invested in plan design, and institutional standards all affect the quality of the plan, which in turn influences clinical outcomes and patient prognosis. In recent years, automatic planning has developed rapidly, which can improve the efficiency of planning design while ensuring the quality of the plan. At present, there are several methods dedicated to the automation of radiotherapy planning design, such as the Rapid Plan and Auto-Planning functions in Eclipse and Pinnacle commercial treatment planning systems, and there are also studies applying artificial intelligence technology in dose prediction to achieve automatic planning. In this article, the research progress on automatic radiotherapy planning was reviewed, and the realization principles, clinical efficacy and existing problems of various automatic planning methods were illustrated.

Objective To test the accuracy and reliability of Axesse accelerator for volumetric modulated arc therapy (VMAT).Methods The accuracy and reliability of Axesse accelerator for VMAT were tested in a stepwise manner, from the simple to the complex and from the part to the whole.For the parts of the system, the stability of dosimetric output and the position accuracy of multi-leaf collimator (MLC) were tested.For the process of the system, the variable VMAT dose rates and gantry speed modulation, the MLC speed and dose rate modulation, and dosimetric verification in patients were tested.Results Compared with fixed gantry irradiation, the variation in dosimetric output was below 1.0% for rotary irradiation including the slide rotary irradiation of the dynamic MLC.The MLC position error of 0.5 mm was visible using the electronic portal imaging system of Axesse, iViewGT 3.40.The MLC position accuracy was within 1 mm for fixed gantry irradiation and rotary irradiation.In the range of the dose rate applied in clinical practice, the testing results of variable VMAT dose rates and gantry speeds as well as variable dose rates and MLC speeds showed that the variation between different strip-field beam intensities was below 2.0%.Using a gamma criterion of 3 mm/3%, the pass rates in dosimetric verification of patients with cervical cancer, prostate cancer, and breast cancer were 96.52%, 95.72%, and 98.83%, respectively.Conclusions The Axesse system can precisely control MLC motion, variable dose rates, and gantry speeds in VMAT.The Axesse system is accurate and reliable for VMAT.
