Objective To investigate the effect of postoperative reduction quality in femoral neck fracture internal fixation on mechanical properties of the femoral head from the perspective of trabecular bone biomechanics.Methods From patients who underwent hip replacement surgery for femoral neck fractures,a total of 26 femoral head slice specimens were obtained.The central axis of the primary compressive trabeculae was defined as the 0° group,with the intersection point of the primary compressive trabeculae and the femoral calcar serving as the center.By rotating the specimens to simulate different reduction angles,the cut femoral head slice specimens were randomly divided into five groups:-10°,-5°,0°,5°,and 10°,representing femoral heads with varying reduction qualities.The specimens were subjected to single compression load tests and fatigue load tests.The load was set from 70 N to 1 400 N,at a frequency of 1 Hz,with 10 000 cycles.Axial stiffness,displacement,and the number of collapse cycles were measured,to compare the biomechanical properties of femoral head specimens under different reduction qualities.Results There were differences in the axial stiffness,displacement,and number of collapse cycles among the femoral head specimens in different groups.Under 800 N load,the axial stiffness of 0° group was significantly greater than that of±10° groups(P＜0.05).The axial stiffness of 0° group was also greater than that of the±5° groups,but the differences were not statistically significant(P＞0.05).The axial stiffness of±5° groups was greater than that of±10° groups(P＜0.05).0° group had a lower displacement than±5° groups and±10° groups.However,the differences in displacement between 0° group and±5° groups were not statistically significant(P＞0.05),while the differences between the 0° group and±10° groups were statistically significant(P＜0.05).The differences in displacement between±5° groups and±10° groups were also statistically significant(P＜0.05).0° group had a significantly higher number of collapse cycles than±10° groups(P＜0.05).The number of collapse cycles in 0° group was also higher than that in±5° groups,but the differences were not statistically significant(P＞0.05).The number of collapse cycles in±5° groups was significantly higher than that±10° groups(P＜0.05).Conclusions The quality of reduction after internal fixation of femoral neck fractures significantly affects the biomechanical properties of the femoral head.This study provides a scientific basis for optimizing treatment and postoperative management,aiming to improve clinical outcomes and patients' quality of life.

Bronchial asthma(hereinafter referred to as asthma)is a common chronic respiratory disease characterized by airway inflammation,airway hyperresponsiveness,and airway remodeling.Its pathogenesis is highly complex and heterogeneous,involving multiple factors such as genetics,immunity,and environmental exposure.Currently,therapeutic options for asthma remain relatively limited,making it an urgent priority to explore its underlying mechanisms,identify effective treatment strategies,and develop new drugs.In this context,the establishment of animal models for asthma plays an irreplaceable and crucial role.However,to date,no single ideal animal model has been able to fully and accurately replicate all the features of the onset and progression of human asthma.This study systematically reviews the research progress over the past five years in the establishment methods of asthma animal models.It provides a detailed overview of commonly used experimental animals(such as mice,rats,and guinea pigs),frequently used sensitizing agents(including ovalbumin,house dust mite,lipopolysaccharide,and toluene diisocyanate),and the methods for establishing asthma models using these animals and sensitizers.This study also presents an objective evaluation of the advantages,limitations,and applicability of each model.Evaluation criteria for asthma models are summarized across multiple dimensions,including behavioral assessments,pulmonary function,histopathology,immunological indicators,and pharmacodynamics.Although methods for establishing refractory asthma models remain underdeveloped,several strategies for modeling refractory asthma have been summarized through a review of relevant literature,aiming to provide useful references for related research.Based on current scientific and technological advancements,it is anticipated that future research on asthma animal models will focus more on clinical relevance,technological innovation,and multidisciplinary integration.Specifically,future models are expected to adopt multi-sensitizer induction protocols,apply cutting-edge tools such as gene editing,enhance clinical relevance and promote diversification and personalization of models.Furthermore,advanced technologies such as bioimaging and biosensing are anticipated to enable dynamic monitoring of airway inflammation and remodeling.Organ-on-a-chip platforms may also be explored as potential alternatives to traditional animal models.The ultimate goal is to develop multifactorial,composite models that better simulate the complexity and heterogeneity of human asthma.

Objective To explore the promoting effect of egg yolk oil combined with heat-clearing and detoxi-fying traditional Chinese medicine external washing on postoperative wound healing in patients with perianal abscesses based on growth factors in the wound granu-lation tissue.Methods Eighty patients with perianal abscesses admitted to our hospital from January 2023 to May 2023 were randomly divided into a control group and an observation group,with 40 patients in each group.Three days after surgery,the control group received routine treatment,such as external washing with heat-clearing and detoxifying Chinese herbal medicine and dressing changes with vase-line gauze.The observation group received additional treatment with egg yolk oil,and both groups were treated continuously for 7 days.The clinical efficacy,improvement in clinical symptoms,and wound recovery at different time points;serum inflammatory cytokines;and expression levels of wound granulation tissue-related factors were compared between the two groups.Results The total effective rate was higher in the observation group than the control group(95%vs.75%,P<0.05).The time of pruritus disappearance,decaying flesh,emer-gence of new epithelium,and healing were shorter in the observation group than in the control group(P<0.05).The pain degree,wound secretion,granulation morphology and surrounding tissue edema score of the observation group were significantly decreased at 7 and 10 days after surgery compared with the control group(P<0.05).Serum levels of interleukin(IL)-1β,IL-8,and tumor necrosis factor-α were lower in the observation group than the control group at 7 and 10 days after surgery(P<0.05).The levels of basic fibroblast growth factor,vascular endothelial cell growth factor,and transforming growth factor-βin wound granulation tissue were higher in the observation group than the control group at 7 and 10 days after surgery(P<0.05).Conclusion The external application of egg yolk oil combined with heat-clearing and detoxifying Chinese herbs can significantly improve the clinical symptoms of patients with perianal abscesses and promote wound healing,with significant therapeutic effects.This may be related to the inhibition of inflammatory cytokine expression and the promotion of wound granulation tissue growth factor expression.

Objective:To propose a method to measure the femoral anteversion angle based on the three-dimensional model of femur.Methods:From January 2019 to December 2023, a total of 50 patients (100 femurs) with patellar instability who underwent full-length CT examination of both lower limbs in Tianjin Hospital were retrospectively analyzed, including 16 males and 34 females, aged 28.5±11.9 years (range, 16-57 years). All patients underwent CT examination of both lower limbs, and the imaging data were imported into Mimics 21.0 software as DICOM format files. The femur was extracted by the threshold segmentation function, and the 3D model of the femur was reconstructed by appropriate trimming and smoothing. Three-dimensional models of the femur from 30 patients (60 femurs) were selected and imported into 3-matic 13.0 software for labeling of anatomical points and drawing of axes. The angle between the axis of the distal femur and the axis of the proximal femur was the femoral anteversion angle. Two observers positioned the spatial coordinates of the intercondylar fossa apex, the greater trochanter apex, the center of the femoral head, the femoral through-condylar axis and the posterior condylar tangent marker points on a 3D model of the femur to compare the differences between the groups. The femoral anteversion angles measured by different three-dimensional measurement methods were compared with the clinically reported femoral anteversion angles.Results:The difference between the femoral head center and intercondylar fossa apex coordinate data of 30 patients (60 femurs) measured by the two observers was not statistically significant ( P>0.05), whereas the data for the Y-axis coordinate of the greater trochanter apex were 25.77±23.21 and 22.08±25.73, respectively, and the difference was statistically significant ( t=2.906, P=0.017). The difference between the data of femoral through condylar and posterior condylar tangential coordinates of 30 patients (60 femurs) measured by the two observers was not statistically significant ( P>0.05). Using the femoral mechanical axis as the projection direction, the angle between the transcondylar axis and the posterior condylar tangent line was 5.97°±2.02° (range, 1.48°-12.08°). The anterior tilt of the femur measured by the two observers in the femoral neck cylinder fitting method was 23.35°±7.45° and 24.94°±9.01°, respectively, and the difference was statistically significant ( t=-2.147, P=0.040). The anterior inclination of the femur measured by the two observers in the femoral head ball enlargement method was 24.63°±7.66° and 25.12°±8.84°, the difference was not statistically significant ( t=-0.820, P=0.419). Using the femoral head ball expansion method to locate the proximal femoral axis, two observers measured the anterior tilt angle of the femur in 50 patients (100 femurs) according to the method described above, which was 23.30°±9.41° and 23.57°±9.97°, respectively, without a statistically significant difference ( t=-0.664, P=0.508), both smaller than the 29.56°±8.74° measured based on two-dimensional images in the imaging report, and the difference was statistically significant ( P<0.05). Conclusion:The femoral anteversion angle measured by the angle between the axis of the femoral condyle and the axis of the femoral neck based on the three-dimensional model is accurate and effective, and the measured value is smaller than that based on the two-dimensional images in clinical practice.
