ObjectiveTo explore the complex network relationships among pain, kinesiophobia, social participation and knee function in patients after total knee arthroplasty (TKA), and to analyze the moderating effects of different socio-structural factors on the rehabilitation network from an ethical equity perspective. MethodsA convenience sampling method was used to select 291 patients who underwent TKA in Qilu Hospital of Shandong University from May to July, 2023. Pain was assessed using Numerical Rating Scale, kinesiophobia with Chinese short version of the Tampa Scale for Kinesiophobia, social participation with Impact on Participation and Autonomy Questionnaire, and knee function with Hospital for Special Surgery Knee Score. A partial correlation network among pain, kinesiophobia, social participation and knee function was constructed using Graphical Least Absolute Shrinkage and Selection Operator. Key variables were identified through node centrality and bridge centrality analysis. Network Comparison Tests (NCT) were used to analyze network differences among subgroups based on different socio-structural characteristics. ResultsIn the network model, the nodes with the highest strength centrality were indoor participation, activity behavior and activity pain. Bridge centrality analysis indicated that activity pain, knee function, indoor participation and activity cognition were key bridge nodes. NCT revealed no significant differences in overall network structure or global strength among subgroups based on residence, education level or payment method (P > 0.05). However, significant differences in edge weights were found for specific edges such as activity cognition-activity behavior and knee function-indoor participation (P < 0.05). ConclusionThere is a network of interactions among pain, kinesiophobia, social participation and knee function in patients after TKA, with nodes such as indoor participation and activity pain playing key roles in the rehabilitation process. Although the overall rehabilitation network is similar across different socio-structural groups, variations exist in specific relational pathways among patients from rural areas, those with lower education levels, and those with out-of-pocket payment. This suggests that clinical rehabilitation interventions should focus on these core nodes and implement targeted support strategies for socio-structurally disadvantaged groups to promote rehabilitation equity.

ObjectiveTo address the challenges of unstructured classical Chinese expressions， nested entity relationships， and limited annotated data in famous traditional Chinese medicine（TCM） case records， this study proposes a joint relation extraction framework that integrates data augmentation and entity mapping， aiming to support the construction of TCM diagnostic knowledge graphs and clinical pattern mining. MethodsWe developed an annotation structure for entities and their relationships in TCM case texts and applied a data augmentation strategy by incorporating multiple ancient texts to expand the relation extraction dataset. A cascade binary tagging framework for relation triple extraction（CasRel） model for TCM semantics was designed， integrating a pre-trained bidirectional encoder representations from transformers（BERT） layer for classical TCM texts to enhance semantic representation， and using a head entity-relation-tail entity mapping mechanism to address entity nesting and relation overlapping issues. ResultsExperimental results showed that the CasRel model， combining data augmentation and entity mapping， outperformed the pipeline-based Bert-Radical-Lexicon（BRL）-bidirectional long short-term memory（BiLSTM）-Attention model. The overall precision， recall， and F₁-score across 12 relation types reached 65.73%， 64.03%， and 64.87%， which represent improvements of 14.26%， 7.98%， and 11.21% compared to the BRL-BiLSTM-Attention model， respectively. Notably， the F₁-score for tongue syndrome relations increased by 22.68%（69.32%）， and the prescription-syndrome relations performed the best with the F₁-score of 70.10%. ConclusionThe proposed framework significantly improves the semantic representation and complex dependencies in TCM texts， offering a reusable technical framework for structured mining of TCM case records. The constructed knowledge graph can support clinical syndrome differentiation， prescription optimization， and drug compatibility， providing a methodological reference for TCM artificial intelligence research.

Objective To analyze the status of willingness to participate in health science popularization (HSP) and its influencing factors among medical workers in Guangdong Province. Methods A total of 462 medical workers in Guangdong Province were recruited as the study subjects using a stratified convenience sampling method. The Questionnaire on Influencing Factors of Willingness to Participate in Health Science Popularization, developed by the research team, was used to investigate their willingness to participate in HSP and related variables, including previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support. Hierarchical regression analysis was used to identify the influencing factors of willingness to participate in HSP. Results The median and 25^th and 75^th percentiles score of willingness to participate in HSP was 4.0 (3.8, 4.5), indicating a moderately high level of willingness. The HSP participation willingness score was positively correlated with scores for previous communication experience, attitude, moral belief, descriptive norm, injunctive norm, self-efficacy, and social support (Spearman correlation coefficients were 0.513, 0.384, 0.507, 0.533, 0.463, 0.556, and 0.435, respectively; all P<0.01). Hierarchical regression analysis showed that previous communication experience, moral belief, descriptive norm and self-efficacy positively predicted willingness to participate in HSP (all P<0.05). Medical workers in the non-Pearl River Delta region had lower willingness than those in the Pearl River Delta region for HSP participation (P<0.05). Conclusion There is still room for improving willingness for HSP participation among healthcare professionals in Guangdong Province. It is recommended to enhance self-efficacy through communication skills training, strengthen professional ethics education, foster a positive peer engagement atmosphere, and intensify resource support and capacity building for HSP in the non-Pearl River Delta region, to improve HSP participation willingness among medical workers in Guangdong Province.

ObjectiveTo determine the effects of tuina at "Weizhong （BL 40）" on mechanical pain hypersensitivity in a rat model of chronic dorsal root ganglion （CCD）， and to preliminarily explore the anatomical distribution characteristics of neural afferents associated with "Weizhong （BL 40）" acupoint and their central projections. MethodsThirty SD rats were randomly assigned to a sham operation group， a model group， and a tuina group， with 10 rats in each group. In the model group and the tuina group， a chronic compression of CCD model was established by implanting stainless-steel rods into the right L4/5 and L3/4 intervertebral foramina. Rats in the sham operation group underwent surgical exposure only. From day 4 to day 28 after modeling， rats in the tuina group received daily manipulation at the right "Weizhong （BL 40）" （pressure： 5 N； frequency： 2 Hz； duration： 10 min/session）. Rats in the sham operation group and the model group were subjected only to fixation. Mechanical withdrawal threshold （MWT） was assessed before modeling and on day 3， 7， 14， 21， and 28 after modeling. On day 29 after modeling， pseudorabies virus （PRV）， a retrograde trans-multisynaptic tracer， was injected into the right "Weizhong （BL 40）" acupoint in rats from the model group. After 120 h， rats were perfusion-fixed through the heart， and local tissues surrounding the "Weizhong （BL 40）" acupoint， corresponding lumbar dorsal root ganglia， lumbar spinal cord， and brain tissues were collected for fluorescence imaging of PRV-positive signals. ResultsCompared to the sham operation group， rats in the model group and the tuina group showed significantly reduced MWT on day 3， 7， 14， 21， and 28 after modeling （P＜0.05）. Compared to the model group， rats in the tuina group exhibited significantly increased MWT on day 21 and 28 after modeling （P＜0.05）. Fluorescence imaging revealed PRV-positive signals in the deep fascial layer of local muscle tissue at "Weizhong （BL 40）"， the L4 and L5 dorsal root ganglia， the dorsal horn and central canal region of the spinal cord， as well as the primary somatosensory cortex （S1）， secondary motor cortex （M2）， and anterior cingulate cortex （ACC）. Among the examined cortical regions， M2 contained the largest number of PRV-positive neurons. ConclusionTuina at "Weizhong （BL 40）" alleviates mechanical hyperalgesia in rats with the chronic compression of CCD model. A traceable neuroanatomical connection exists between the linking deep tissues within "Weizhong （BL 40）" region and the corresponding lumbar dorsal root ganglia， the spinal dorsal horn， and specific cortical areas.

Objective:To explore the effects of Jianpi Mixture on the glucose receptor/glucagon like peptide-1 (GLP-1)/5-hydroxytryptamine (5-HT) signaling pathway and the mechanism of Jianpi Mixture in improving visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome (IBS-D) rats.Methods:Totally 40 healthy male SPF rats were divided into blank group, model group, Jianpi Mixture low- and high-dosage groups according to the random number table method, with 10 rats in each group. Except for the blank group, the rest of the rats were prepared by the "senna gavage combined with restraint stress" method to replicate the IBS-D spleen deficiency model. The aqueous extract of Jianpi Mixture was 2.52 and 7.56 g/kg in the low- and high-dosage groups, and the same volume of normal saline was given to the blank group and the model group, once a day, for 14 days. On the 1st, 7th and 14th days of administration, the body weight of rats was recorded, the fecal traits of the rats were scored with Bristol score, the visceral sensitivity of IBS-D rats was evaluated by the abdominal wall retraction reflex score (AWR) under rectal dilation, the morphology of colonic mucosal tissues was observed by HE staining, and the protein expressions of T1R2, SLGT1, GLUT2, GLP-1 and 5-HT in colon tissues were detected by immunohistochemical staining.Results:On the 1st, 7th and 14th days of administration, compared with the model group, the weight of the rats in the Jianpi Mixture high-dosage group increased ( P<0.05); on the 14th day of administration, the fecal Bristol score decreased significantly ( P<0.05) and the AWR score increased ( P<0.05); HE staining showed that the mucosal epithelium of colon tissue in the model group was slightly damaged, and local edema was visible. The pathological condition of colonic mucosa in the Jianpi Mixture low- and high-dosage groups was effectively improved; compared with the model group, the expressions of T1R2 and GLP-1 in the Jianpi Mixture low- and high-dosage groups increased ( P<0.05), and the expression of 5-HT decreased ( P<0.05); the protein expressions of GLUT2 and SGLT1 in the Jianpi Mixture high-dosage group increased ( P<0.05). Conclusion:Jianpi Mixture can treat spleen-deficiency IBS-D by restoring the normal expression of intestinal glucose receptors, regulating the secretion of GLP-1/5-HT, improving intestinal motility and alleviating visceral hypersensitivity.

Objective:To explore the clinical efficacy of acupuncture combined with hemoperfusion in hemodialysis patients with intractable pruritus.Methods:A retrospective clinical study was conducted. A total of 126 hemodialysis patients with intractable pruritus were enrolled from June 2023 to June 2024 and divided into two groups (63 cases each) based on treatment modalities. The control group received hemoperfusion alone, while the observation group received acupuncture combined with hemoperfusion. Both groups were treated for 3 months. The Modified Pruritus Duo's Score was used to evaluate pruritus severity, the Pittsburgh Sleep Quality Index (PSQI) for sleep quality, and the 36-Item Short Form Health Survey (SF-36) for quality of life before and after treatment. Serum β 2-microglobulin (β 2-MG) and parathyroid hormone (PTH) levels were measured using immunoturbidimetry and chemiluminescence, respectively. Clinical efficacy was assessed. Results:The total effective rate was 98.42% (62/63) in the observation group and 78.77% (49/63) in the control group, with a statistically significant difference ( χ2=16.90, P<0.001). Post-treatment scores for pruritus severity, affected areas, frequency, sleep interference, and total pruritus score in the observation group were significantly lower than those in the control group ( t values were 16.94, 12.23, 12.67, 12.71, 23.91, respectively, P<0.001). The observation group also exhibited lower post-treatment serum β 2-MG [(13.24±3.11) mg/L vs. (17.61±4.58) mg/L, t=10.46] and PTH [(198.11±96.12) ng/L vs. (249.27±88.45) ng/L, t=6.72] levels were lower than those in the control group ( P<0.001). Additionally, the observation group demonstrated significantly lower scores in subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, daytime dysfunction, and total PSQI score ( t values were 14.97, 6.98, 2.06, 23.63, 2.68, 3.56, 14.89, respectively, P<0.001), as well as higher scores in physical health, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health domains of SF-36 ( t values were -3.13, -4.35, -6.34, -7.90, -4.49, -5.30, -5.00, -3.95, respectively, P<0.05). Conclusion:Acupuncture combined with hemoperfusion effectively alleviates pruritus, reduces serum β 2-MG and PTH levels, improves sleep quality, and enhances overall quality of life in hemodialysis patients with intractable pruritus, demonstrating superior efficacy compared to hemoperfusion alone.

ObjectiveTo evaluate the effects of Wuhua herbal tea on chronic unpredictable mild stress (CUMS)-induced depression and explore its mechanism of action in combating depression.MethodsWe tested the antidepressant effects of Wuhua herbal tea in a rat model of CUMS-induced depression using fluoxetine as a positive control. The rats were divided into four groups: control group, model group, fluoxetine group, and Wuhua herbal tea group. The rats underwent body weight measurements, sucrose preference test, and open-field test. Enzyme-linked immunosorbent assay kits were used to detect the serum levels of serotonin, dopamine, adrenocorticotropic hormone (ACTH), corticosterone, norepinephrine, and interleukin-6. Intergroup comparisons and detection of brain-derived neurotrophic factor (BDNF), cAMP-response element binding protein (CREB), Janus kinase 2 (JAK2), and signal transducer and activator of transcription 3 (STAT3) mRNA expression in the hippocampus were performed using RT-PCR. Immunohistochemistry was used to identify the expression of phosphorylated JAK2 (p-JAK2) and phosphorylated STAT3 (p-STAT3) proteins in hippocampal paraffin sections of CUMS rats.ResultsCompared with the control group, the model group rats had depressive tendencies, exhibiting low vitality and interest in various behavioral indicators which were signs of despair. The Wuhua herbal tea group statistically increased the levels of serotonin and dopamine in the serum of CUMS rats to varying degrees (P = .015 and P = .002); reduced serum levels of ACTH, corticosterone, norepinephrine, and interleukin-6 (all P .05); and decreased mRNA expression of BDNF, CREB, JAK2, and STAT3 in the hippocampus (all P .05); and decreased p-STAT3 protein levels (P = .006).ConclusionWuhua herbal tea shows antidepressant potential in CUMS rats by modulating the HPA axis and inhibiting JAK2-STAT3 overactivation, alleviating neuroinflammation. It also restores BDNF-CREB pathway function, reducing depressive symptoms.
