Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

BACKGROUND:In recent years,human pluripotent stem cell derived kidney organoids and rodent models of diabetic kidney disease have also made some progress.However,because the pathogenesis of diabetic kidney disease is affected by environmental factors and genetic factors,the pathogenesis is complex,and the clinical treatment for diabetic kidney disease patients needs to vary from person to person.Therefore,more flexible and integrated approaches need to be developed,leading to the discovery of strong preclinical evidence to support more targeted interventions in patients with diabetic kidney disease.OBJECTIVE:To reviewthe research progress of diabetic kidney disease model from the aspects of diabetic kidney disease animal model,two-dimensional cell culture simulation diabetic kidney disease model,and three-dimensional organoid diabetic kidney disease model,to provide clues and ideas for further research.METHODS:China National Knowledge Network and PubMed databases were searched with"diabetes,diabetic nephropathy,diabetic kidney diseases,diabetic nephropathy models,diabetic nephropathy animal models,organoids,diabetic and organoids,diabetic and kidney organoids,kidney organoids,diabetic nephropathy cell models,diabetic nephropathy syndrome combined animal models"as Chinese and English search terms.Totally 101 articles were finally included for review and analysis.RESULTS AND CONCLUSION:Both in vivo and in vitro models of diabetic kidney disease are powerful tools to further study the pathogenesis of diabetic kidney disease.The interactions between multiple systems can be observed in animal models.Two-dimensional cell culture is easy to operate and low cost.The emerging kidney organoids fill the gap between two-dimensional and global levels,without species differences,and simulate the complexity of human kidney to a certain extent.With the continuous development of organoid technology,kidney organoids are expected to provide a new perspective for exploring the pathogenesis,pathophysiology,and drug screening of diabetic kidney disease.

Objective To explore the ArcCHECK system-based methods for dose verification of ultra-long target for cervical cancer VMAT so as to assure the precision of cervical cancer radiotherapy.Methods A total of 33 patients with ultra-long target(target length≥26 cm)admitted to some hospital for cervical cancer VMAT from 2021 to 2023 were selected retrospectively,and radiotherapy plans were designed for the patients with VMAT technology and verified dosimetrically with different methods.Firstly,the dose distribution data were collected respectively at 5 and 8 cm away from the center of the ArcCHECK system along the bed exit direction,and enrolled into Group Test 1 and Test 2 respectively.Then the ArcCHECK system was flipped 180°,and the dose distribution data were acquired at 8 cm away from the center along the bed exit direction and included into Group Test 3.Dose merging between Group Test 2 and Test 3 with the Merge function was carried out to obtain the dose distribution data which were divided into Group Test 4.The monitor units of Group Test 1,2 and 4 were summarized,and difference analyses were performed on the length of the target area,detection point and irradiation time.Group Test 1,2 and 4 were compared in terms of γ pass rate,normalized dose deviation,confidence limit(CL)of pass rate and acceptance rate(γ pass rate≥95%and γ pass rate≥90%).Spearman's correlation coefficient was used to correlate the parameters such as maximum transverse diameter,length,volume and monitor unit of the target area and expected execution time of the plan.SPSS 19.0 software was used for statistical analysis.Results Group Test 1,2 and 4 had the monitor unit being(758.76±107.63)MU,and had statistically significant differences in length of the target area,detection point and irradiation time(P<0.01).In Group Test 4 γ pass rate under 2%/2 mm criterion did not reach 90%,and in Group Test 1 and 2 γ pass rates under 3%/3 mm and 3%/2 mm criteria both amounted to 95%.Group Test 1,2 and 4 had statistically significant differences in γ pass rate and normalized dose deviation(all P<0.05).In Group Test 1 there were more than 90%of the verification results where γ pass rate≥95%and more than 95%where γ pass rate≥90%under 3%/3 mm criterion.The monitor unit was positively correlated with the maximum transverse diameter,length and volume of the target area,respectively(0.337≤r≤0.568,P<0.05),and the expected execution time of the plan was positively correlated with the volume and monitor unit of the target area,respectively(0.457≤r≤0.517,P<0.01).Conclusion The dose verification method with the target at 5 cm away from the center along the bed exit direction can be applied clinically with high feasibility to the dose verification during the radiotherapy of the cervical cancer VMAT patients with ultra-long target,with the safety of the verification devices ensured effectively.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To evaluate the reliability and validity of the Chinese version of the hyperacusis scale and estimate its applicability in the Chinese population.Methods The patients admitted to the Department of Oto-laryngology of Xijing Hospital from June 2017 to December 2017 were surveyed.A total of 300 questionnaires were sent out and 293 valid questionnaires were collected with effective response rate of 97.67％.All participants comple-ted a basic information survey,pure tone audiometry and fill in the Chinese version of the hyperacusis scale.The re-liability and validity of this scale were evaluated.Results Among the 293 respondents,243(82.93％)were compli-cated with tinnitus.A total of 181 cases(61.77％)were subjectively diagnosed with hyperacusis through question-naire survey.According to the scale evaluation,174 cases(59.39％)were diagnosed with hyperacusis,and the Kappa value of conformity test of the two methods was 0.81(P＜0.001).Reliability analysis indicated a Cronbach'sα coefficient of 0.93 for the entire scale.Each dimension had a Cronbach's α coefficient＞0.60.The split-half relia-bility coefficient for the entire scale was 0.86,and for each dimension,it was＞0.60.Exploratory factor analysis of validity suggested that 25 items could be grouped under 4 factors,such as functional part,social part,emotional part and harmonic sensitivity part.These factors had eigenvalues greater than 1,accounting for 59.42％of the total variance.Post-rotation,the 25 items were distributed across the 4 components,with each item having a factor load-ing＞0.40.Confirmatory factor analysis of validity showed model fit parameters as:x2/df=1.98,GFI=0.91,AGFI=0.83,CFI=0.92,TLI=0.89,RMSEA=0.08.Each item had a standardized factor loading＞0.40.Con-clusion The Chinese version of the hyperacusis scale demonstrated strong reliability and validity,making it suitable for use among the Chinese population.
