With the rapid advancement of hemodynamic indices and monitoring technologies, their classification methods and application processes have become increasingly complex. Currently, no unified standard hasbeen established, making it difficult to fully meet the clinical requirements for hemodynamic management. To assist in hemodynamic monitoring assessment and therapeutic decision-making in critically ill patients, the Critical Hemodynamic Therapy Collaborative Group, in conjunction with the Critical Ultrasound Study Group, has jointly developed the Standard for the Application of Hemodynamic Monitoring Techniques in Critical Care. The first part of this standard systematically categorizes hemodynamic indicators into flow indicators, pressure and its derivative indicators, and tissue perfusion indicators, while elaborating on the clinical application of each. The second part establishes a standardized clinical implementation pathway for hemodynamic monitoring. It proposes a tiered monitoring strategy-comprising basic, advanced, indication-specific, and special scenario monitoring-tailored to different clinical settings. It emphasizes the central role of critical care ultrasound across all levels of monitoring and establishes hemodynamic assessment standards for organs such as the brain, kidneys, and gastrointestinal tract. This standard aims to provide a unified framework for clinical practice, teaching, training, and research in critical care medicine, thereby promoting standardized development within the discipline.

Metabolic associated fatty liver disease （MAFLD） is a common chronic liver disease worldwide， and timely and precise intervention can delay disease progression and significantly reduce the risk of serious complications such as liver fibrosis， liver cirrhosis， and liver cancer. Although traditional liver biopsy combined with metabolic markers is the gold standard， it may cause complications such as pain and bleeding as an invasive examination， which has promoted scientific research to shift its focus to the construction of noninvasive assessment systems. In recent years， noninvasive diagnostic technologies based on multi-dimensional detection strategies have been continuously updated， including serological models， imaging techniques， and clinical algorithms. This article systematically reviews the screening methods for MAFLD during the fibrotic stages F1—F3， especially deep learning models based on artificial intelligence， in order to provide ideas for the early screening of MAFLD， as well as a scientific reference for optimizing disease management strategies.

AIM: To investigate the value of maximum standardized uptake value(SUVmax), extraocular muscle(EOM)diameter, and thyroid stimulating hormone receptor antibody(TRAb)in evaluating inflammatory activity in thyroid-associated ophthalmopathy(TAO).METHODS: TAO patients underwent orbital 99mTc-DTPA SPECT/CT imaging at the Affiliated Hospital of Panzhihua University between January 2023 and December 2024 were retrospectively enrolled. According to the clinical activity score(CAS), patients were classified into an active group and an inactive group. SUVmax and EOM were independently measured by three nuclear medicine physicians, and the mean values were used for analysis. Serum TRAb levels from TAO patients were measured using a fully automated electrochemiluminescence immunoassay analyzer. Nonparametric tests were used to compare differences between the two groups. Spearman correlation analysis was performed to assess the correlations of CAS with SUVmax, EOM, and TRAb. Using CAS as the reference standard, receiver operating characteristic(ROC)curves were plotted to evaluate the diagnostic performance of SUVmax, EOM, and TRAb, as well as their combination. Intraclass correlation coefficient(ICC)was used for reliability analysis to evaluate the consistency of SUVmax and EOM among the 3 measurers.RESULTS: A total of 99 patients(198 eyes)with TAO were enrolled in this study, including 38 males and 61 females, aged 16-74(46.92±11.84)y. The active group comprised 46 patients(92 eyes), aged 16-71(48.40±12.02)y, with 25 males and 21 females. The inactive group included 53 patients(106 eyes), aged 17-74(45.46±11.59)y, consisting of 13 males and 40 females. There were no statistically significant differences between the two groups in terms of gender and age(P>0.05). Statistically significant differences were observed in SUVmax, EOM, and TRAb. Compared with the inactive group, the active group showed higher SUVmax, EOM, and TRAb levels(all P<0.01). Correlation analysis showed that CAS was positively correlated with SUVmax, EOM, and TRAb(r=0.734, 0.622, and 0.404, respectively, all P<0.01). ROC curves were plotted using CAS as the reference standard, and the AUCs for SUVmax, EOM, TRAb, and their combined diagnosis were 0.874, 0.797, 0.715, and 0.892, respectively. The ICC of SUVmax and EOM were 0.925(95%CI: 0.901-0.948, P<0.001)and 0.943(95%CI: 0.907-0.964, P<0.001)respectively.CONCLUSION: Beyond CAS, there is a need to identify objective imaging and serological biomarkers. Measurements of SUVmax and EOM provide visualized and quantifiable tools for assessing TAO activity, and their combination with TRAb can further improve the accuracy of activity assessment.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. 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.

Objective:To formulate a community teacher standard for the training of general practitioner program (direction in hospice care).Methods:This was a qualitative study. Twenty-nine experts in general practice and hospice care from various teaching hospitals and community health service centers were invited to participate in two rounds of Delphi consultation from April to August 2022. Based on the results of the consultation, a standard for community faculty training in comprehensive care and end-of-life care for general practitioners was formulated, and the weight coefficients of the indicators were calculated.Results:Of the 29 experts, 11 (37.9%) were male, their age was (52.9±8.9) years, and their working life was (17.0±7.2) years. In the two rounds of expert consultation, the expert positive coefficient was 100.0% (29/29) and 96.6% (28/29), the expert authority coefficient was 0.789 and 0.851, and the expert opinion coordination coefficient W of the importance of all indicators was 0.124 and 0.131, respectively ( χ2=123.01, 131.71, P<0.05). Finally, a set of community-based teacher standard for general practitioner specialty training (direction in hospice care) was established, which consisted of 4 first-level indicators and 30 second-level indicators. The four first-level indicators were basic literacy, clinical qualification and ability, teaching qualification and ability, and scientific research ability, all with the weight coefficients of 0.254, 0.254, 0.252 and 0.240, respectively. Conclusion:The standard of teachers in the community base of general practitioner specialty training (direction in hospice care) established in this study is more scientific, which is conducive to the comprehensive evaluation of teachers in the community training base.

Objective:To analyze the clinical efficacy of the pelvic unlocking reduction device in assisting closed reduction and internal fixation for the treatment of AO/OTA 61-C3 type pelvic fractures.Methods:A retrospective analysis was conducted on 27 patients with AO/OTA 61-C3 pelvic fractures treated with the pelvic unlocking reduction device-assisted reduction and internal fixation between January 2020 and January 2024 in Fourth Medical Center of the People's Liberation Army General Hospital. The cohort included 11 males and 16 females, with a mean age of 30.2±13.9 years (range, 13-55 years). The time from injury to surgery was 16.0 (10.0, 28.0) d (range, 6-175 d). According to the AO/OTA classification, there were 8 cases of type 61-C3.1, 10 cases of type C3.2, and 9 cases of type C3.3. Among them, 10 patients presented with associated lumbosacral nerve injuries, classified as Gibbons grade II in 5 cases, grade III in 1 case, and grade IV in 4 cases. All patients underwent closed reduction and internal fixation assisted by the pelvic unlocking reduction device. Postoperative outcomes were assessed using the visual analogue scale (VAS) for pain, the Majeed pelvic score, and the Harris hip score. Fracture reduction quality was evaluated using the Matta criteria, and overall health status was assessed using the 36-Item Short Form Health Survey (SF-36).Results:All patients successfully underwent the surgery and were followed up for 31.6±12.3 months (range, 12-48 months). The fracture reduction time was 33.45±12.18 min, the total operative time was 283.0±87.9 min, the number of fluoroscopies was 71.33±32.77, and the intraoperative blood loss was 314.1±252.6 ml. At the 12-month postoperative assessment, VAS score was 1.78±0.85, Majeed pelvic score was 87.52±15.03; SF-36 score was 88.93±11.27; and Harris Hip Score was 90.59±11.43. All patients achieved an "excellent" rating according to the Matta radiographic assessment criteria at 12 months postoperatively. Fracture union was confirmed in all cases, with a healing time of 2.9±0.4 months (range, 2.5-3.5 months). No postoperative complications such as shock, nonunion, delayed union, surgical site infection, implant loosening, or deep vein thrombosis were observed. Three patients experienced numbness in the lateral thigh region postoperatively, which was attributed to lateral femoral cutaneous nerve injury. The symptoms resolved completely following removal of the INFIX internal fixator.Conclusion:The pelvic unlocking reduction device-assisted closed reduction and internal fixation demonstrates safety and efficacy in treating AO/OTA 61-C3 type pelvic fractures, yielding satisfactory fracture union and early functional scores.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.
