ObjectiveTo investigate whether macrophage lipolysis-stimulated lipoprotein receptor (LSR) deficiency affects the progression of metabolic dysfunction-associated steatohepatitis (MASH) by activating the Yes-associated protein (YAP) signaling pathway. MethodsMale wild-type (WT) mice and macrophage-specific Lsr knockout (LsrMφKO, KO) mice, with an age of 8 weeks and similar body weights, were selected and fed with a normal diet, a high-fat diet (HFD), or a high-fat high-cholesterol (HFHC) diet for 30 weeks. HE staining and oil red O staining were used to evaluate liver pathological changes; immunofluorescent staining was used to measure the expression levels of F4/80 and α-smooth muscle actin; RT-qPCR and Western blot were used to measure the levels of markers associated with lipid metabolism, inflammation, and fibrosis. Bone marrow transplantation rescue experiments (WT→KO vs KO→KO groups) were conducted to explore the functional role of LSR in macrophages. At the cellular level, hepatic macrophages were isolated from WT and KO mice to measure the expression levels of YAP signaling pathway-related proteins and their downstream target genes, and in addition, these cells were treated in vitro with verteporfin (VP), a specific inhibitor of YAP, to verify the regulatory effect of this pathway on the expression of inflammatory factors. The independent samples t-test was used for comparison of normally distributed measurement data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed measurement data. ResultsUnder the condition of normal diet, there were no significant differences in hepatic indicators between WT and KO mice. KO mice fed an HFD or HFHC diet showed a significant increase in hepatic lipid droplet accumulation, accompanied by lipid metabolism disorder and significant increases in the levels of indicators associated with inflammation and fibrosis (P<0.05). Bone marrow transplantation experiments confirmed that compared with the KO→KO group, the WT→KO group had significant alleviation of liver injury (P<0.05). Mechanistic studies showed that there were significant reductions in the levels of phosphorylated large tumor suppressor kinase 1 (LATS1) and phosphorylated YAP and significant increases in the expression levels of total YAP protein and its downstream target genes in hepatic macrophages of KO mice (P<0.05). In vitro VP intervention significantly inhibited the expression levels of inflammatory factors in hepatic macrophages isolated from KO mice (P<0.05). ConclusionMacrophage LSR deficiency activates the YAP signaling pathway by inhibiting LATS1/2 kinase activity and promotes the expression of inflammatory factors, thereby accelerating the progression of liver injury in a mouse model of MASH.

Objective To explore the influence of different hardness surfaces on gait coordination in patients with functional ankle instability(FAI). Methods Qualisys Infrared Optical Motion Capture System was used to test the coordination and variability of 15 FAI patients on the right side at Nanjing Normal University from May to July,2023.The gait cycle data were collect-ed and intercepted,and coupling angle(CA)and standard deviation of coupling angle(SDCA)were calculated by Matlab to compare the differences on different hardness surfaces. Results On coronal plane,CA of hip-ankle joint was higher on the hard surface than on the soft surface during middle stage of support and early stage of swing,and lower on its rest stages and the gait stages of hip-knee joint and knee-ankle joint than on the soft surface(P<0.01).On sagittal plane,CA of hip-ankle joint and knee-ankle joint was smaller on the hard surface than on the soft surface during middle and late stages of support,and larger than on the soft surface during their rest stages,and the gait stages of hip-knee joint(P<0.01).On horizontal plane,CA of hip-knee joint was lower on the hard surface than on the soft surface during the late stage of support,and higher than on the soft surface during its early stage of swing and bearing stage of hip-ankle joint(P<0.01).Compared with the hard surface,SDCA was smaller on the soft surface than on the hard surface only in the hip-ankle on the sagittal plane and during bearing stage of hip-knee joint,and was greater than on the hard surface for the rest(P<0.01). Conclusion FAI patients showed more distal dominance on soft surface than on hard surface during most gait cycle on 3D plane,i.e.,advantage of ankle varus and plantar flexion increased,and advantage of hip joint decreased;the coordination variability was generally higher on soft surface than on hard surface.These findings suggested that FAI patients may increase the risk of recurrent lateral ankle sprain walking on soft surface.

According to random number table method, these patients were divided into observation group and control group as 98 cases each. Conventional care and hospital discharge were used for control group. On the basis of this, multidimensional integration and 360° support were used for patients of observation group. The function of family and marriage, quality of life in patients were assessed before and after 3 months of the intervention. The treatment adherence was evaluated in 3 months and 6 months after intervention.Results:Before intervention, the marriage family function score, marital satisfaction, conflict resolution methods and the relationship with friends and family, husband and wife exchange scores of the observation group were (2.3 ± 0.5), (24.6 ± 6.1), (25.7 ± 7.1), (28.2 ± 6.9), (28.8 ± 6.9) points, respectively. Three months after intervention, these scores were (2.5 ± 0.7), (31.6 ± 5.0), (31.7 ± 5.3), (28.1 ± 6.8), (29.0 ± 7.1) points, respectively. There was statistically significant difference between before and after the intervention ( t values were -2.371 - 8.631, P < 0.01). These scores of control group before the intervention were (2.3 ± 0.6), (24.5 ± 6.2), (25.2 ± 7.2), (32.5 ± 6.0), (33.9 ± 6.3) points, respectively. Three months after intervention, these scores were (2.3 ± 0.4), (24.5 ± 6.2), (26.1 ± 6.9), (29.1± 4.8), (28.5 ± 7.2) points. Significant differeces were found between before and after the intervention in control group ( t values were -3.878-6.323, P < 0.05 or 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 2.675-8.631, P<0.01). As for observation group, planning (62.8 ± 27.2 vs. 75.5 ± 25.4) and intimate relationship (62.8 ± 25.2 vs. 78.2± 24.9) in quality of life were obviously difference before and after 3 months of intervention ( t values were 3.050, 3.639, P < 0.01). As for control group, planning (62.5 ± 27.6 vs. 65.7 ± 24.9) and intimate relationship (65.8 ±25.2 vs. 63.5 ± 23.8) in quality of life were obviously difference before and after 3 months of intervention ( t values were 2.375, 3.132, P < 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 3.050, 3.639, P < 0.01). The treatment adherence of observation group was significant better than control group. After 6 months intervention, the treatment adherece of observation group was 83.67% (82/98), while the treatment adherece of control group was 44.89% (44/98), significant differences were found btween the two groups ( χ2 value was 0.511, P < 0.01).
