The Healthy China 2030 Plan set the goal of reducing premature deaths from diabetes by 30% by 2030. However, there has been a lack of assessment of premature mortality for diabetes since the action plan was issued. This study used data from the Global Burden of Disease Study 2021, calculated the premature deaths for diabetes by sex, provinces, and subtypes from 1990 to 2021. We explored the temporal trend of premature mortality using the average annual percent change (AAPC) for different sexes, provinces, and subtypes from 1990 to 2021. Furthermore, we predicted premature mortality for diabetes through 2030 for China and its provinces according to the average annual change rate from 2010 to 2021. There was a first slow upward trend in premature mortality for diabetes from 0.5% in 1990 to 0.6% in 2004, and then a decline until 2021 with premature mortality of 0.4%. By 2030, only Fujian (30.3%) will achieve the desired level of reduction, with only seven provinces meeting the target for females and none for males. There is a large range in the degree of decline between inland and coastal regions, showing obvious geographic differences, and there should be a focus on balancing medical resources.

Objective:To establish a method for determining the sialylation levels of N-glycan profiles based on ion-exchange chromatography in glycoprotein drugs.Methods:The separation was performed in a column picking with anion-exchange resin(4.6 mm × 250 mm,5 μm,or equivalent).Mobile phase A was 20％ acetonitrile solution,while mobile phase B was a 20％acetonitrile solution containing 0.1 mol·L-1 ammonium formate(pH 4.5).The flow rate was 0.60 mL·min-1.Detection was performed using a fluorescence detector with excita-tion and emission wavelengths of 330 and 420 nm,respectively.The injection volume was 5 μL.Results:Within the target loading sample range of 40％ to 160％,the peak area showed a good linear relationship with protein concentration(r＞0.99).The average recovery rates at three concentration levels were 106.25％,100.00％,and 106.67％,respectively.The limit of quantification was 0.03％.Conclusion:This method is suitable for detecting the sialylation levels of N-glycan profiles in various glycoprotein drugs.

Objective To establish a high-performance liquid chromatography method to detect the purity of human epidermal growth factor(hEGF),to compare the stability of the products of different enterprises by purity results,and to provide technical support for improving quality control and unified monitoring of hEGF based on national drug sampling and testing.Methods Agilent 300SB C8 column(250 mm×4.6 mm,5 μm)was used.Mobile phase A was 7.5 mmol·L-1 sodium phosphate buffer(pH 6.8),and mobile phase B was acetonitrile,the column temperature was 30℃,the flow rate was 0.6 mL·min-1 with gradient elution,and the detector wavelength was set at 280 nm.Results The resolution between the main peak of hEGF and the adjacent impurity peak was more than 1.5,with a detection limit of 6 ng.This method has been successfully applied to determine the purity of the bulk and final products.The results showed that the purity of the final products decreased compared with the bulk.The maximum impurity that increased significantly was the deamidation impurity identified by the mass spectrometry.Conclusion Based on the typical sample of the full chain and multi-dosage form,the established method had good specificity and resolution for the preliminary identification and purity determination of hEGF bulk and final products.

This study aims at elucidating on the concept, strategy and implementation effect of constructing medical English teaching resource based on multi-online medium in medical colleges and universities. The medical English teaching resource based on multi-online medium breaks through the limitations of traditional paper-based teaching materials, optimizes the existing teaching resources and forms a multi-dimensional medical English teaching system with multi-modal interactions. It not only transforms the teaching organization of medical English course, but also innovates the teaching concept, teaching mode as well as teaching methodology. It has important practical significance for improving the medical English learning environment of medical college students and improving the teaching quality and efficiency of medical English course.
