ObjectiveTo evaluate the clinical efficacy of Huayu Tongluo Formula （化瘀通络方， HTF） in patients with mid-stage diabetic kidney disease of blood stasis syndrome and explore its potential mechanisms. MethodsA multi-center， randomized， double-blind， placebo-controlled clinical trial was conducted. Ninety patients of mid-stage diabetic kidney disease of blood stasis syndrome were divided into a control group of 46 cases and a treatment group of 44 cases. Both groups received conventional western medicine treatment， the treatment group additionally taking HTF， while the control group taking a placebo of the formula. The treatment was administered once daily for 24 weeks. The primary outcomes included 24-hour urine total protein （24 h-UTP）， serum albumin （Alb）， glycated hemoglobin （HbA1c）， and serum creatinine （Scr）.The secondary outcomes included changes in levels of endothelin-1 （ET-1）， nitric oxide （NO）， vascular endothelial growth factor （VEGF）， and traditional Chinese medicine （TCM） syndrome scores before and after treatment. Clinical efficacy was evaluated based on TCM syndrome scores and overall disease outcomes. Adverse reactions and endpoint events were recorded. ResultsIn the treatment group after treatment， 24 h-UTP， ET-1， and VEGF levels significantly decreased （P＜0.05）， Alb and NO levels significantly increased （P＜0.05）； while the TCM syndrome scores for edema， lumbar pain， numbness of limbs， dark purple lips， dark purple tongue or purpura， and thin， rough pulse all significantly decreased （P＜0.05）. In the control group， no significant changes were observed in any of the indicators after treatment （P＞0.05）.Compared with the control group， the treatment group showed significant reductions in 24 h-UTP， ET-1， and VEGF levels， and increases in Alb and NO levels （P＜0.05）. The TCM syndrome scores for edema， lumbar pain， dark purple tongue or purpura， and thin， rough pulse were all lower in the treatment group than in the control group （P＜0.05）. The total effective rate of TCM syndrome in the treatment group was 59.09% （26/44）， and the overall clinical effective rate was 45.45% （20/44）. In the control group， these rates were 15.22% （7/46） and 8.7% （4/46）， respectively， with the treatment group showing significantly better outcomes （P＜0.05）. A total of 7 adverse events occurred across both groups， with no significant difference （P＞0.05）. No endpoint events occurred during the study. ConclusionOn the basis of conventional treatment of Western medicine， HTF can further reduce urinary protein levels and improve clinical symptoms in patients with mid-stage diabetic kidney disease of blood stasis syndrome. The mechanism may be related to its effects on endothelial function.

Objective:To investigate the imaging quality of CBCT under different exposure parameters and the relationship between subjective and objective evaluation.Methods:CBCT scanners of 6 different suppliers[3D Accuitomo(Morita),i-mCAT(Kavo),5G(NewTom),Smart3D(Beijing Langshi),DCT Pro(Vatech),Vgi(NewTom)]were used to scan the spatial resolution models and head simulators under typical exposure conditions(different device with different tube voltage and current for exposure).The visibility of SedentexCT IQ phantom and anatomical structures generated by different CBCT scanners were compared.For objective evaluation,7 professional evaluators scored CBCT imaging qualities.For subjective evaluation,the resolution(LP/mm)of the images were com-pared among the devices.Results:No significant difference was found by 7 evaluators either intra or inter of the teams.By objective e-valuation,the score of NewTom 5G was 2,that of i-CAT was 5 and that of the others was 4.By subjective evaluation,the LP/mm of i-CAT was 1.8,that of Smart3D was 2.0 and that of the others was 1.0-1.7.The subjective evaluation of image quality obtained un-der different tube voltages and tube currents were significantly different.Conclusion:The subjective and objective evaluations of image quality are approximately consistent.The difference of the subjective image quality may be produced by the different tube voltage and current for exposure.

BACKGROUND:Excessive accumulation of uric acid in the body can lead to diseases such as hyperuricemia and gout,which is a risk factor for cardiovascular and renal dysfunction.Many sports medicine organizations at home and abroad advocate the formulation of exercise prescription to prevent and treat chronic diseases,but this method has not been effectively carried out in the prevention and treatment of hyperuricemia. OBJECTIVE:Based on an overview of the formation of hyperuricemia and the regulation of uric acid by exercise and its related mechanisms,to condense a program suitable for popular exercise to prevent and assist in the treatment of hyperuricemia,and to propose precautions to be taken when exercising for patients with different stages of hyperuricemia. METHODS:PubMed and CNKI were searched for relevant literature published before October 2023 using the keywords of"uric acid,gout,aerobic exercise,strength training,high-intensity interval training,obesity"in English and Chinese,respectively.Initial screening was done by reading the titles and abstracts to exclude repetitive studies and literature with irrelevant content,and finally 64 papers were included for review. RESULTS AND CONCLUSION:The formation of hyperuricemia is caused by excessive synthesis of uric acid by the liver,insufficient excretion by the kidneys,or both.Exercise can improve the uric acid level in the body by regulating the activity of antioxidant enzymes,the expression of uric acid excretion protein and lipid metabolism.Aerobic exercise,strength training,high-intensity intermittent exercise can effectively regulate uric acid levels,reduce inflammation,promote the expression of uric acid excretion protein and lipid metabolism,and achieve good results in the prevention and treatment of hyperuricemia.Currently,there is a lack of research on the mechanisms underlying direct regulation of uric acid levels by exercise,and future studies need to explore in greater depth the possible mechanisms of regulation of uric acid levels by exercise and refine the effects of different exercise modalities on patients with different characteristics of hyperuricemia.

Objective Based on the technology acceptance model,to explore the influence mechanism of technical support,perceived interactivity,perceived usefulness,perceived ease of use and perceived risk on medical staff's report intention on adverse events,and to provide path suggestions for improving medical staff's report intention adverse events.Methods The multi-stage sampling method was used to select 637 medical staffs of tertiary public hospitals in Hangzhou who used the information-based platform to report adverse events as the research respondents,and the self-developed scale of report intention on adverse events was used as the research tool,monofactor analysis were conducted by Wilcoxon rank-sum test,and the structural equation model was used to analyze the influence path of their report intention on adverse events.Results Perceived ease of use and perceived usefulness have positive effects on medical staff's report intention on adverse events(β=0.264,0.658;P＜0.001);Perceived risk negatively affected the medical staff's report intention on adverse events(β=-0.143,P＜0.001).The indirect effects of perceived usefulness and perceived ease of use on medical staff's report intention on adverse events are 0.538 and 0.205,respectively.Conclusion Perceived usefulness and perceived ease of use plays a mediating role in perceived interactivity and medical staff's report intention on adverse events.

Objective To explore the mediating effect of coping styles of newly graduated nurses between personality traits and transitional shock,aiming to provide references for managers to help new nurses reduce the level of transitional shock and smoothly go through the role transition period.Methods By convenience sampling,580 new nurses from 13 tertiary A hospitals in Guangzhou,Changsha,and Zhuzhou were surveyed from May to October 2023.A general information questionnaire,Eysenck Personality Questionnaire short form,Transition Shock of Newly Graduated Nurses Scale,and Brief Coping Style Scale were used for the survey.Structural equation modeling was employed to examine the mediating effect of newly graduated nurses'coping styles between personality traits and transitional shock.Results A total of 537 new nurses participated in the survey.Psychoticism and neuroticism were positively correlated with transformational shock and negative coping styles(P＜0.01),but negatively correlated with positive coping styles(P＜0.01).Extroversion was negatively correlated with transformational shock and negative coping style(P＜0.0 1),but positively correlated with positive coping style(P＜0.01).The results of the mediation effect analysis show that coping styles play a partial mediating role between personality traits and transformational shock.The mediating effects of coping styles on psychoticism,extraversion,and neuroticism are 0.095,-0.051,and 0.134,respectively,accounting for 43.18％,30.36％,and 32.29％of the total effect.Conclusion Coping styles of newly graduated nurses act as mediating variables between personality traits and transitional shock.Nursing managers should pay attention to cultivating good individual personality traits and establishing a supportive work environment to enhance new nurses'positive coping and reduce the level of transitional impact.

Objective:To profile the distribution of avian influenza virus in poultry-related environment in poultry industry developed area in Fujian province, an investigation was conducted in Nanping city from Dec.2021 to Dec.2023.Methods:The samples from multiple types of external environment related to poultry in Nanping city were collected from Dec. 2021 to Dec. 2023, and the real-time fluorescence quantitative RT-PCR used to detect and subtype the influenza A virus (FluA). SPSS 26.0 software was used to analyze the distribution characteristics of FluA in poultry-related environment and the differences in time, places and sample types.Results:The overall positive rate of FluA in samples from poultry-related environment was 49.16% (1 435/2 919). The positive rates of H3, H5, H9 and H10 subtypes were 0.72% (21/2 919), 9.42% (275/2 919), 33.20% (969/2 919), 0.89% (26/2 919) respectively, and no H7 subtype was detected. The positive rate of mixed type (more than one subtype of FluA detected in a same sample) was 6.51% (190/2 919), and the positive rate of unknown subtype (positive for FluA but negative for H3/5/7/9/10) was 11.58% (338/2 919). The higher positive rate of FluA mainly occurred in autumn-winter season (September to February of the following year). In live poultry markets and slaughterhouses, the positive rates of FluA, H9 subtype, mixed type and unknown subtype were significantly higher than that in poultry farms. The positive rate of FluA in poultry drinking water and feces was higher than samples of other types, most of the positive samples were H9 subtype.Conclusions:The positive rate of FluA in poultry-related environment in Nanping city was higher in autumn-winter season. The investigation also showed that higher FluA positive rate in drinking water and feces sample and diversity of the virus existed in the place of multiple types of poultry clustered, such as live poultry markets and slaughterhouses.
