The 2021 version of the Baveno Ⅶ consensus on portal hypertension and the 2023 guidelines from the European Association for the Study of the Liver define recompensated cirrhosis as the restoration and stabilization of liver function, improvement of liver fibrosis, and absence of decompensated cirrhosis for a long time following effective treatment of the underlying etiology of cirrhosis. Recompensated cirrhosis has become an important research direction in the field with the gradually increasing number of these patients. Temporary recompensation, stable recompensation, and long-term recompensation are the three stages into which patients with cirrhosis are divided, based on varying recompensation stages. Clinical characteristics and prognosis are significantly different among different stages. Patients in the temporary compensation stage have significant fluctuations in their condition and poor stability, with a high risk of recurrent complications. The prognosis of patients in the stable recompensation stage is significantly affected by the cause and the type of initial decompensation event, while the condition of patients in the long-term recompensation stage is more stable, and the long-term prognosis is close to that of compensated cirrhosis. This article aims to summarize and explore the recompensation rates at different stages of liver cirrhosis, the occurrence risk of various complications and liver cancer, and long-term management and treatment following recompensation, providing new directions for future research in this field.

Ferroptosis is regarded as a novel and regulatable form of cell death, with its main characteristics being abnormal iron metabolism and the accumulation of lipid peroxides. Although there have been breakthroughs in the research of ferroptosis in tumors and degenerative diseases, its research in skin diseases is relatively scarce. Starting from the development of the concept of ferroptosis, this article expounds the basic characteristics and regulatory mechanisms of ferroptosis. In the field of skin diseases, we emphasize the importance of ferroptosis and discuss in detail the research and application of ferroptosis in various skin diseases, aiming to provide effective guidance for the treatment and clinical practice of various skin diseases, and offer new ideas for the future research direction of skin diseases.

Objective:To explore the effects of mechanical factors on the morphology of the growth plate and proximal femur development, in order to provide a mechanical basis for the mechanism of Cam lesions in femoral acetabular impingement (FAI).Methods:Using CT scan data of hip joint from adolescents, we constructed three-dimensional finite element models of normal and extended proximal femoral epiphyseal growth plates. Dynamic mechanics and position data from daily activities (walk, stand on one and two feet, go upstairs and downstairs, sit and stand up, squat and stand up) and basketball layup drills were collected from five healthy volunteers using the Vicon system. The mean values of femoral head mechanical loads and positions at peak values, movement onset, and termination were selected for finite element analysis to observe the distribution of equivalent stress, normal stress, and shear stress on the two growth plate models under different activity modes.Results:Successful construction of three-dimensional finite element models for normal and extended proximal femoral epiphyseal growth plates was achieved. Mechanical load values and spatial positions of the femoral head during daily activities and layup movements were obtained. In daily activities, peak equivalent stress values for normal and extended growth plates ranged from 1.6 to 11.0 MPa; compressive stress ranged from 1.7 to 12.0 MPa; tensile stress ranged from 0.5 to 10.0 MPa; and shear force ranged from 0.4 to 7.1 MPa. The compressive stress during walking, standing on one or both feet, going up and down stairs, sitting and standing, and squatting was concentrated in the central and lateral areas; tensile stress was concentrated in the central and medial areas; shear force was concentrated in the medial area and the anterior and posterior edges of the growth plate. During a layup, the compressive stress in the center, outer upper side, and medial edge of the growth plate of the normal model was notably concentrated, with peaks fluctuating between 5.5-19.0 MPa, 5.7-11.0 MPa, and 5.4-7.3 MPa respectively; tensile stress and shear force were concentrated at the inner and outer edges as well as in the central area, with peaks fluctuating between 3.0-24.0 MPa and 3.0-26.0 MPa respectively, these values were significantly different from those observed during daily activities. For the elongated growth plate, compressive stress was concentrated at the central and lateral edges with peaks fluctuating between 17.0-41.0 MPa and 17.0-38.0 MPa respectively; simulated shear stress and tensile stress showed significant concentration at peaks fluctuating between 4.9-34.0 MPa, also significantly different from those observed during daily activities.Conclusion:The difference in mechanical distribution between daily activities, basketball layup training, as well as between normal and extended growth plates may be the mechanical initiating factor in the development of extended growth plates and the formation of Cam lesions, it may be the mechanical initiating factor for the development of extended growth plates and the collision of Cam lesions in FAI.
