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 （Lsr^MφKO， 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.

ObjectiveTo reveal the influence of Jianchangbang characteristic processing method on the change process of volatile components and the processing mechanism of reducing toxicity and increasing efficiency of Magnoliae Officinalis Cortex（MOC） by studying the changes in the composition and content of volatile components during the processing of ginger processed Xingpo pieces. MethodSamples of raw products， ginger juice moisturized products and stir-fried and heap moisturized products of MOC were taken according to the set time points， and headspace gas chromatography-mass spectrometry（HS-GC-MS） was used to determine the contents of volatile components in the samples， and the relative content of each component was obtained by peak area normalization. Principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA） were performed on the sample data using SIMCA 14.1 software， and the differential components during the processing were screened with variable importance in the projection（VIP） value>1 as the indicator. ResultA total of 68 volatile components were identified in the samples， among which some of the chemical components with similar structures showed similar trends of changes， and there was also the phenomenon of interconversion between compounds. Compared with the raw products， the contents of 42 components in ginger juice moisturized products increased， while the contents of 25 components decreased， 19 components were unique， and 4 components were unique to the raw products. Compared with ginger juice moisturized products， MOC in the early stage of piling had three unique components， and the contents of 11 components such as cyclosativene and （+）-α-pinene increased， and the contents of 5 components such as tricyclic terpene and α-curcumene decreased， and ginger juice moisturized products had four unique components. Compared with the early stage of piling， in the later stage， the contents of 8 components such as （+）-α-pinene and camphene significantly increased， while the contents of 6 components such as linalool and α-selinene significantly decreased. During the processing of MOC， there were significant changes in the chemical composition of the samples before and after 20 days. The differences between ginger juice moistening and the early stage of piling， the early stage and the later stage of piling could be clearly distinguished. ConclusionDuring the preparation process of ginger processed Xingpo pieces， the addition of ginger juice can reduce the contents of stimulating components， and the contents of active components continue to increase in several stages， such as the addition of ginger juice， frying and heap moisturizing， the quality of the decoction pieces may change significantly at about 20 d of processing. This study can provide a research basis for exploring the processing mechanism of ginger processed Xingpo pieces.

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.

Objective To investigate the correlation between the infarction location and progressive motor deficits (PMD) occurrence.Methods The patients with middle cerebral artery(MCA) infarction within 24 h of onset without thrombolytic therapy were included.The National Institutes of Health Stroke Scale(NIHSS) motor item score increase ≥2 points of the base line within 7 d after stroke onset served as the PMD diagnostic criteria.The differences in clinical and laboratory data,and infarction location were compared between the PMD group and non-PMD group.The multivariate Logistic regression analysis predicted the risk factors of PMD occurrence.Results A total 121 patients with MCA acute cerebral infarction were included in the study and divided into the PMD group (45 cases) and non-PMD group (76 cases).The internal watershed infarction occurrencerate in the PMD group was higher than that in the non-PMD group (26.7 ％ vs.5.3％,p=0.001).The occurrence rate of penetrating arterial infarction (PAI) had no statistical difference between the PMD group and non-PMD group(42.2％ vs.35.5％,P=0.463).PAI was further divided into perforating branch atheromatous disease (BAD) and lipohyalinitic degeneration (LD).The occurrence rate of BAD in the PMD group was significantly higher than that in the non-PMD group (28.9％ vs.9.2％,P=0.005).The stepwise Logistic regression analysis indicated that watershed infarction [odds ratio (OR):9.750,95 ％ confidence interval(CI):2.828-33.612,P=0.000] and BAD lesion (OR:6.036,95 ％ CI:2.119-17.190,P =0.001) were the independent risk factors contributing to PMD.Conclusion Internal watershed infarction and BAD lesion may predict the PMD occurrence.The infarct location is conducive to find the high risk population of cerebral infarction progress.

Objective To study the impact of earthquake disasters on the mental health of military medical personnel during emergency rescue. Methods Three hundred military medical personnel who participated in the emergency rescue of earthquake disasters in five military hospitals in Shaanxi Province were selected as the study subjects, and their mental health levels were analyzed using the Mental Symptom Checklist 90 (SCL-90). Results In this survey, a total of 300 SCL-90 questionnaires were issued, 300 were recovered, and the effective recovery rate was 100%. Only 30.67%(92/300) of people participated in emergency disaster rescue during investigation, 31.33% (94/300) had psychological problemsafter arriving in the earthquake-stricken area after one week, such as somatization, obsessive-compulsive disorder, anxiety, and horror. SCL-90 scores were 0.45±0.03, 1.13±0.13, 0.79 ±0.08, 1.07±0.09, 1.01±0.14. The psychological stress response rates of the emergency response of military medical staff of different characteristics were different. Among them, the stress response rates of military personnel with different degrees (specialty, bachelor or above) and whether they have participated in rescue work were 74.07% (40/54), 21.95% (54/246), 15.22% (14/92), 38.46% (80/208).The difference was statistically significant (χ2=55.913,16.018, P<0.01). Conclusions The medical staff of the army participating in the earthquake disaster rescue has psychological pressure due to many injuries, environmental risks, lack of supplies, etc. The medical unit should provide adequate training in theory and practice to its personnel and focus on the mental health of rescue workers, give timely psychological counseling to ensure the successful completion of the rescue.

Objective To observe the influence of adrenocorticotropic hormone (ACTH4-10) in the changes of podocyte proliferation,apoptosis and expression of nephrin and podocin on adriamycin (ADR)-induced podocyte injury and investigate the protective effect of ACTH4-10.Methods All podocytes were randomly divided into following groups:normal control,ADR-induced group and ACTH4-10 intervention group (low,middle and high concentration).Normal control group was not treated,ADR-induced group was induced to set the model of podocyte injury by ADR (1 μmol/L) for 24 hours and ACTH4-10 intervention groups were intervened by 1 μg/L,10 μg/L and 100 μg/L ACTH4-10 for 1 hours respectively,prior to setting the model of podocyte injury.Cell counting kit (CCK-8) was used to detect the multiplication of podocytes and TUNEL apoptosis detection kit was used to detect podocyte apoptosis.Real-time PCR and Western blotting were used to examine the expression of nephrin and podocin.Results Compared with control group,podocyte proliferation and expression of nephrin and podocin was decreased significantly in ADR-induced group (P ＜ 0.05),meanwhile podocyte apoptosis was increased obviously (38.14％ vs 5.12％).Compared with ADR-induced group,podocyte proliferation and expression of nephrin and podocin was increased generally with concentration of ACTH4-10.Although podocyte apoptosis rates (20.45％,17.39％,11.02％) were increased in ACTH4-10 intervention group (low,middle and high concentration) while comparing with normal control group,podocyte apoptosis decreased obviously while comparing with ADR-induced group.Conclusions ACTH4-10 can stabilize the expression of nephrin and podocin on slid diaphragm,and has the protective effect on podocyte injury induced by ADR,while the effect depends on the concentration of ACTH4-10.
