Under the background of breaking the " five only" evaluation criteria, continuously optimizing the scientific research performance evaluation system of hospitals to mobilize the enthusiasm and creativity of scientific researchers and guide the direction of scientific research development plays an important role in enhancing the overall scientific research capability of hospitals. Through literature analysis and expert consultation, a certain hospital has constructed a personal scientific research performance evaluation index system for medical staff in tertiary public hospitals, oriented towards innovation quality and member contributions, and began to implement it throughout the hospital in 2021. This index system included four categories of scientific research performance: vertical scientific research projects, academic influence, science and technology awards, and transformation of achievements, with a total of 20 indicators. The annual scientific research performance score of an individual would serve as the basis for the distribution of year-end scientific research performance and an important reference for applying for key and major projects within the hospital. After the application of this evaluation index system, the enthusiasm of medical staff for scientific research has been effectively stimulated. The average individual scientific research performance score increased from 0.974 in 2020 to 1.220 in 2023. All scientific research indicators involved in the evaluation system have shown growth, with a significant increase in high-quality results. This evaluation system can provide a reference for the scientific research performance evaluation of public hospitals under the background of breaking the " five only" evaluation criteria.

A case of giant liquid tophus in both lower legs was reported. The patient was a 41-year-old man with a history of gout for more than 10 years. The patient had hyperlipidemia and prediabetes, and the long-term use of hormone cortisol drugs was suspected. After standardized treatment for lowering uric acid, reducing blood lipids, and correcting glucose intolerance, the patient lost 12 kg over six months. The patient was admitted to the hospital upon discovering symmetrical enlargement of both calves. Ultrasound showed subcutaneous masses with clear boundaries behind the gastrocnemius muscle, approximately 14.9 cm×6.7 cm on the left and 13.6 cm×4.6 cm on the right. Based on the clinical information and morphological features, a diagnosis of gouty tophus was made. Following ultrasound-guided puncture drainage, aspirate about 200 mL fluid from the subcutaneous masses of each lower legs. The patient continued to receive standardized uric acid-lowering treatment and the patient′s condition improved. For such atypical giant liquid tophus, clinical practitioners should remain vigilant, differentiating them from tumors, infections, autoimmune diseases, and promptly perform pathological examinations through puncture to be diagnosed. After a definitive diagnosis, surgical excision can be performed concurrently with standardized uric acid-lowering treatment to achieve a favorable prognosis.

Objective:To investigate the risk factors of diabetic kidney disease (DKD) in type 2 diabetes mellitus (T2DM) patients in plain-sand areas and loess hilly areas of Gansu province.Methods:A total of 1 599 T2DM patients who participated in chronic disease and risk factors monitoring and basic public health service management were selected by multi-stage stratified random sampling method in the sandy plain areas and loess hilly areas of Gansu province. Questionnaire survey, physical measurement and laboratory tests were performed. Multivariate binary logistic model was used to analyze the influencing factors.Results:The prevalence of DKD was 22.1% (174/787) among T2DM patients in the sandy plain areas and 19.1%(155/812) in the loess hilly area, respectively. Hypertension ( OR=3.022), hyperuricemia ( OR=2.114) and HbA1c≥7%( OR=2.231) were the risk factors for DKD in the plain-sand areas, and the risk of DKD increased with age. In the loess hilly areas, female sex ( OR=0.379) was the protective factor for DKD; while duration of disease≥10 years ( OR=2.476), hyperuricemia ( OR=1.907), HbA1c≥7% ( OR=1.927) were the risk factors for DKD; and the risk of DKD increased with the increase of age, and decreased with the increase of per capita monthly income. Conclusions:The prevalence of DKD and its influencing factors are different between sandy plain areas and loess hilly areas in Gansu province. The prevention and treatment of hypertension should be given more attention in sandy plain areas. In addition, the screening of DKD should be conducted among T2DM patients, particularly for those with old age, hyperuricemia and HbA1c≥7% in both areas of the province.
