ObjectiveTo investigate the preventive effect and mechanism of Dendrobium officinale （DO） on non-alcoholic fatty liver disease （NAFLD） by network pharmacology and animal experiments. MethodsDO components in blood after administration were identified and analyzed using ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-QE-HF-MS/MS）. Network pharmacology and molecular docking methods were employed to obtain active ingredients and potential targets of DO for NAFLD control. High-fat feeds were used to replicate the NAFLD rat model. Biochemical kits were used for detecting the expression levels of blood lipids， hepatic lipids， and liver functions of rats. Hematoxylin-eosin （HE） staining and oil red O staining were employed to observe pathological changes in rat liver， and real-time fluorescence quantitative PCR （Real-time PCR） assay was performed to validate potential targets obtained from the network pharmacology analysis. ResultsA total of 13 DO components were identified in blood， including berberine， dihydrosanguinarine， and oxypeucedanin. A total of 14 potential targets were screened through network pharmacology， including Forkhead box protein O1 （FoxO1）， epidermal growth factor receptor （EGFR）， and insulin-like growth factor 1 （IGF-1R）， involving pathways such as the advanced glycation end product （AGE）/receptor for AGE （RAGE） signaling pathway， blood lipids and atherosclerosis， insulin resistance， and FoxO signaling. The results of animal experiments showed that the NAFLD rat model was successfully replicated. After the preventive treatment with DO for NAFLD rats， the indexes of blood lipids， hepatic lipids， and liver function were normalized； lipid deposition and lesions in the liver were significantly improved； the expression level of FoxO1 mRNA in the liver was significantly reduced （P<0.05）， and the mRNA expression levels of phosphatidylinositide 3-kinases （PI3K）， protein kinase B （Akt）， EGFR， and IGF-1R were significantly increased （P<0.05）. ConclusionDO has a preventive effect on NAFLD rats， and the mechanism of action may be related to the modulation of IGF1R and EGFR targets and activation of the PI3K/Akt/FoxO1 signaling pathway.

Objective To develop and validate a risk prediction model for social dysfunction in middle-aged and elderly patients with ischemic stroke.Methods A non-matched case-control study was conducted among ischemic stroke patients admitted to the neurology department of a tertiary hospital in Tangshan between August 2022 and March 2023.Patients who developed social dysfunction within 3 months after discharge were assigned to a case group,while those without it were assigned to a control group.Multivariate logistic regression was used to identify significant predictors and construct a nomogram-based prediction model.The model's discrimination and calibration were assessed using the area under the receiver operating characteristic curve(AUC)and the Hosmer-Lemeshow test.Internal validation was performed via bootstrap resampling,and clinical utility was evaluated using decision curve analysis.Results Logistic regression identified the following as significant risk factors for social dysfunction(P＜0.05):male gender,age≥60 years,primary education or below,rural residence,income＜3 000,cognitive impairment,low disability acceptance,poor self-management ability,suboptimal utilization of chronic disease resources,low future-oriented coping,and high cumulative ecological risk.The nomogram achieved an AUC of 0.874,with a sensitivity of 79.4％and specificity of 80.7％.The Hosmer-Lemeshow test indicated good calibration(x2=3.631,P=0.88).Conclusion The developed nomogram provides an effective tool for predicting the risk of social dysfunction in middle-aged and elderly ischemic stroke patients,facilitating early identification of high-risk individuals.

Nuclear factor-kappa B （NF-κB） is an important intracellular transcription factor widely involved in the processes such as immune response， inflammatory response， cell proliferation， and apoptosis. The abnormal activation of the NF-κB signaling pathway plays a pivotal role in various liver diseases including chronic hepatitis， liver fibrosis， liver cirrhosis， and hepatocellular carcinoma. Extensive studies have shown that inhibiting NF-κB activity may effectively reduce inflammation and fibrosis and improve metabolic disorders. Several natural compounds， such as matrine and salvianolic acid B， have shown the potential in suppressing NF-κB activity， thereby exerting anti-inflammatory， anti-fibrotic， and anti-tumor effects. This article systematically reviews the critical role of the NF-κB signaling pathway in liver diseases and its potential as a therapeutic target， in order to highlight its potential as a therapeutic target for liver diseases and provide new directions for the treatment of liver diseases.

Promoting the international acceptance of clinical studies about traditional Chinese medicine (TCM) interventions is a key strategy for internationalization of TCM. However, the complexities of TCM interventions—in terms of the theories, practice patterns, and components—pose challenges to the design and implementation of clinical studies that are well accepted by the international community. This article summarized the current status of clinical studies about TCM interventions that were published in international journals, explored underlying barriers hindering the international acceptance, and discussed potential strategies for future development.

Objective To investigate the kinesiophobia level in patients after spinal fracture surgery and their correlations with rehabilitation self-efficacy and adherence. Methods A total of 150 patients who underwent spinal fracture surgery were enrolled in this study. General information was collected from all patients. The Tampa Scale for Kinesiophobia, Self-Efficacy for Rehabilitation Outcomes Scale, department-developed Rehabilitation Adherence Scale and postoperative activity pain [assessed using the Visual Analogue Scale (VAS)] were analyzed. Pearson correlation analysis was used to examine the relationships of kinesiophobia level with rehabilitation self-efficacy and adherence. Multiple linear regression analysis was conducted to identify factors influencing kinesiophobia level. Results The total score of postoperative kinesiophobia level in patients with spinal fracture was (57.14±3.12), which was at a high level. The total score of rehabilitation self-efficacy was (35.19±3.45), which was at a low level. The total score of rehabilitation compliance was (16.46±2.32), which was at a low level. Pearson correlation analysis showed that the total score of kinesiophobia level was negatively correlated with the total score of rehabilitation self-efficacy and rehabilitation compliance (P < 0.05). Univariate analysis revealed statistically significant differences in scores of kinesiophobia level among patients with different educational levels, postoperative activity pain and the presence or absence of postoperative complications (P < 0.05). Multiple linear regression analysis identified self-efficacy (B=-0.271, 95%CI, -0.439 to -0.103), adherence (B=-0.168, 95%CI, -0.331 to -0.004), educational level (B=0.190, 95%CI, 0.020 to 0.361), postoperative complications (B=0.403, 95%CI, 0.233 to 0.573) and postoperative activity pain (B=0.162, 95%CI, 0.003 to 0.320) were the influencing factors of postoperative kinesiophobia level in patients with spinal fracture. Conclusion The patients with spinal fracture have a higher level of kinesiophobia. The influencing factors of level of kinesiophobia are rehabilitation self-efficacy, rehabilitation compliance, education level, postoperative complications and postoperative activity pain.

ObjectiveTo explore the mechanism of Jiawei Wendantang in preventing and treating diabetic atherosclerosis by observing the effect of this prescription on the nuclear factor-κB / NOD-like receptor protein 3（NF-κB/NLRP3） pathway and related inflammatory cytokines in rat model of diabetic atherosclerosis. MethodFifty-four SPF-grade rats were randomized into blank， model， atorvastatin （0.9 mg·kg^-1·d^-1）， and high-， medium-， low-dose （18.2， 9.1， 4.55 g·kg^-1·d^-1， respectively） Jiawei Wendantang groups. The rats in other groups except the blank group were modeled for diabetic atherosclerosis by intraperitoneal injection of streptozotocin and feeding with a high-sugar high-fat diet， and those in the blank group were injected with an equal dose of citric acid buffer and fed with a regular diet. The drug administration lasted for 4 weeks， and the blood glucose level in the tail vein was measured every 6 days. After the last administration， the rats were anesthetized for sample collection. Enzyme-linked immunosorbent assay was employed to measure the serum levels of interleukin-18 （IL-18）， C-reactive protein （CRP）， tumor necrosis factor-α （TNF-α）， and intercellular adhesion molecule-1 （ICAM-1）. Western blot was employed to determine the relative protein levels of NF-κB p65， NLRP3， and ICAM-1 in the abdominal aorta. Real-time quantitative polymerase chain reaction was employed to determine the mRNA levels of NLRP3 and interleukin-1β （IL-1β） in the abdominal aorta. The pathological changes in the thoracic aorta were observed by hematoxylin-eosin staining. ResultCompared with the blank group， the model group showed elevated levels of IL-18， CRP， TNF-α， and ICAM-1 in the serum and blood glucose （P<0.05， P<0.01）， up-regulated protein levels of NF-κB p65， NLRP3， and ICAM-1 （P<0.01）， and up-regulated mRNA levels of NLRP3 and IL-1β （P<0.05）. Compared with model group， Jiawei Wendantang lowered the levels of IL-18， CRP， TNF-α， ICAM-1 and blood glucose （P<0.05， P<0.01）， down-regulated the protein levels of NF-κB p65， NLRP3， and ICAM-1 （P<0.01）， and down-regulated the mRNA levels of NLRP3 and IL-1β （P<0.05， P<0.01）. Moreover， Jiawei Wendantang alleviated the pathological injuries in the thoracic aorta. ConclusionJiawei Wendantang may modulate the NF-κB/NLRP3 signaling pathway to reduce the release and adhesion of inflammatory cytokines and regulate the blood glucose level to treat diabetic atherosclerosis.
