Objective:To explore the optimal index of rotational displacement of femoral neck fractures by modeling the axial rotational displacement of femoral neck fractures after reduction and based on X-ray projections.Methods:Six dry human femur specimens, comprising 2 males and 4 females, were utilized in the study. Design and manufacture a proximal femur ortholateral and oblique X-ray casting jigs and mounts. The femoral neck fracture was modeled on the femoral specimen, with Pauwells 30°, 50°, and 70° models (2 each) made according to Pauwells typing. The fractures were manually repositioned with residual anterior 20°, 40° and 60° axial rotational displacements. Each fracture model was projected at different angles (pedicled 40°, pedicled 20°, vertical 0°, cephalad 20°, and cephalad 40°), and the trabecular angle and Garden's alignment index of the model were measured to observe the imaging characteristics of the fracture line on the medial oblique and lateral oblique radiographs.Results:In the presence of a 20° and 40° anterior rotational displacement following reduction of a femoral neck fracture, the trabecular angle in the rotationally displaced group was not significantly different from that of the anatomically repositioned group in various projection positions. However, when a residual rotational displacement of 60° was present, the trabeculae appeared blurred at most projection angles in the Pauwells 30° and 50° models, failing to measure trabecular angles. In the Pauwells 70° fracture model, the trabecular angle in the rotational displacement group was significantly different from that in the anatomical reduction group. In anteroposterior radiographs, when the anterior rotation displacement was 60° in the Pauwells 70° group, Garden's contralateral index showed an unsatisfactory restoration (150°, 142°), whereas all rotationally displaced models in the Pauwells 30° and Pauwells 50° groups had a Garden's contralateral index of >155°, which achieved an acceptable restoration. In lateral radiographs, all rotational displacement models with Garden's alignment index>180° failed to achieve acceptable repositioning, and the larger the Pauwells angle the greater the Garden's alignment index at the same rotational displacement. In the internal oblique position with a bias towards the foot side, the image showed partial overlap between the femoral head and the shaft, making it difficult to assess the quality of the reduction. Conversely, when projected cephalad, the femoral neck appeared longer, particularly at a projection angle of 40° cephalad, allowing for clear observation of the fracture line and the anatomy of the proximal femur. The trabeculae were not well visualized in the external oblique position.Conclusion:There are limitations in applying the trabecular angle to assess the axial rotational displacement of the femoral head after reduction of femoral neck fractures. The Pauwells 70° with residual rotational anterior displacement of 60° was the only way to detect axial rotational displacement of the femoral head on anteroposterior radiographs Garden's alignment index. For the determination of axial rotational displacement of the femoral head, the Garden's alignment index on lateral radiographs provides higher reliability.

Examining mechanisms involved in the mutual regulation between the muscular system and the skeletal system, elucidating the key issues responsible for loss of muscle and bone mass and strength, and thus halting the progression of these conditions are critical measures for reducing fractures caused by falls and subsequent disability and mortality.At present, most studies have treated the muscular system and the skeletal system separately, often ignoring the mutual regulation and connections between them.This article reviews the current research progress on the mechanisms of interaction between the two systems, aiming to provide a basis for the prevention, diagnosis and treatment of disuse-related diseases in the elderly population.

This paper analyzed the "non-standardization" phenomenon of syndrome differentiation in traditional Chinese medicine （TCM） from the diagnosis process. It is proposed that the symptoms and signs collected by the four examinations of inspection， listening/smelling， inquiry， and palpation naturally have a certain "ambiguity"， which can be reduced by the comparison and comprehensive condensation （comprehensive analysis of the four examinations） of a large amount of multi-dimensional clinical data， thereby realizing the sublimation of TCM diagnosis from "ambiguity" of four examinations to "accuracy" of diagnostic conclusion. Based on the above assumptions， this paper further proposed that a research idea of intelligent syndrome differentiation in TCM， that is， by taking the clinical thinking ability of TCM physicians as the core， adopting artificial intelligence technology based on knowledge graph visualization， integrating the complex network association and reasoning method of "symptom-pathogenesis-syndrome" linked by pathogenesis， and through the automatic analysis and reasoning process of a large amount of multi-dimensional and ambiguous clinical data， the intelligent TCM diagnosis based on syndrome differentiation can be realized.

Gastric Precancerous Lesions(GPL)have the risk of developing gastric cancer,and Spasmolytic Polypeptide Expressing Metaplasia(SPEM)is the initial step of GPL,which has the risk of malignant progression to gastric precancerous lesions.Currently,the exploration of the pathogenesis during this metaplasia stage remains incomplete.Traditional Chinese Medicine(TCM),relying on its solid theoretical foundation and abundant resources of Chinese medicinal materials,possesses unique advantages in the prevention and treatment of GPL.Based on the theory of"spleen deficiency and evil stagnation",we conducts microcosmic syndrome differentiation analysis from the pathophysiological state,markers,and signal pathways of the disease,and proposes to invigorate the spleen and remove blood stasis.The detoxification method is used for treatment,and its feasibility is analyzed in combination with the literature,in order to provide new ideas and strategies for the TCM treatment of SPEM.

Lipedema is a disease in which local fat deposits in the body are the main clinical manifestations. It is often characterized by a disproportionate increase in subcutaneous fat tissue in the extremities, buttocks or hip joints. It is often misdiagnosed as obesity or lymphedema in clinical practice. The pathogenesis is not clearly understood, and there is no standardized clinical treatment method. This paper elaborated on the research status of the pathogenesis of lipedema, and summarized the clinical manifestations and classification, diagnosis and differential diagnosis, treatment methods, etc., aiming to provide up-to-date perspectives of lipedema.

Objective:Previous studies have revealed a correlation between eosinophils and allergic rhinitis,but the causal relationship has not been fully confirmed.This study aims to evaluate the causal link between blood eosinophils and allergic rhinitis using the Mendelian randomization(MR)method. Methods:Summary data from the Genome-Wide Association Study Catalog(GWAS)for eosinophil count(exposure variable)and allergic rhinitis(outcome variable)were collected.GWAS data for the exposure variable were obtained from the IEU Open GWAS Project developed by the Integrative Epidemiology Unit at the University of Bristol,while data for the outcome variable were sourced from the FinnGen Biobank(Finland)database.The causal relationship between eosinophils and allergic rhinitis was analyzed using the two-sample MR method with inverse variance weighted(IVW)analysis.Sensitivity analyses were conducted using the weighted median method,MR-Egger regression,leave-one-out analysis,and funnel plots. Results:An increase in blood eosinophil count showed a potential causal relationship with an increased risk of allergic rhinitis(OR=1.187,95%CI 1.051 to 1.341,P=0.006).This finding was consistent across the weighted median method and MR-Egger regression.Leave-one-out analysis indicated that no single nucleotide polymorphism significantly influenced the causal inference. Conclusion:There is a causal association between increased eosinophil count and a higher risk or worsening of allergic rhinitis.

The surgical reduction and fixation of subtrochanteric femoral fractures are challenging due to its particular anatomical and biomechanical characteristics. Intramedullary nailing is the golden standard for its treatment, but postoperative bone nonunion is a common complication, resulting in limb pain and decreased mobility, which requires a second operation and greatly affects the patients′ life quality. At present, there are many studies on the risk factors of bone nonunion after intramedullary nail fixation, but the risk factors with strong correlation remain unclear and the subsequent treatment plans are diverse, without consensus. Further identification of risk factors can help to select treatment plans. To this end, the authors reviewed the research progress in the risk factors and treatment methods of bone nonunion after intramedullary nailing of subtrochanteric femoral fractures to provide references for its clinical treatment.

Objective To investigate the correlations of the expression of silent information regulator 2 homolog 1 (SIRT1) and colony-stimulating factor 1 receptor (CSF1R) with the clinical characteristics and prognosis of patients with colon cancer. Methods Colon cancer tissue specimens and paracancer tissue specimens were collected from 148 patients with colon cancer. The clinical and pathological features of the patients were analyzed. Immunohistochemistry was used to detect the expression of SIRT1 and CSF1R; the Spearman's correlation analysis was employed to assess the correlation between SIRT1 and CSF1R; the Kaplan-Meier analysis was conducted to evaluate the associations of the expression of SIRT1 and CSF1R with patients' prognosis; the multivariate Cox regression analysis was performed to identify prognostic factors in colon cancer patients. Results Compared with the adjacent tissues, the expression of SIRT1 protein in colon cancer tissues was significantly decreased, and the expression of CSF1R protein was significantly increased (P < 0.05). The expressions of SIRT1 and CSF1R protein were correlated with lymph node metastasis, nerve invasion and invasion depth in patients with colon cancer (P < 0.05). The protein expressions of SIRT1 and CSF1R were negatively correlated (r=-0.536, P < 0.05). The 3-year survival rate of patients with high SIRT1 expression was significantly higher than that of patients with low SIRT1 expression (P < 0.05). The 3-year survival rate of patients with high CSF1R expression was significantly lower than that of patients with low CSF1R expression (P < 0.05). The 3-year survival rate of patients with high SIRT1 expression was significantly higher than that of patients with low SIRT1 expression (P < 0.05). Conclusion In colon cancer, SIRT1 expression is significantly downregulated, whereas CSF1R expression is upregulated, and both are closely related to the clinical and pathological features such as lymph node metastasis, neural invasion, and tumor infiltration depth. Detection of these biomarkers may have important value in predicting patients' prognosis and survival.
