Based on the interactive ritual chain theory, this paper deeply analyzed the interactive characteristics between doctors, patients, and their families in the palliative care environment, as well as explored the role of emotional resonance, symbolic representation, and situational creation in psychological support. It also sorted out four primary issues currently present in psychological support for palliative care patients, including insufficient recognition of caregivers regarding patients’ psychological needs, limited psychological intervention methods, inadequate psychological support capabilities among medical staff, and an imperfect family and social support system. On this basis, a five-dimensional psychological support mechanism was constructed, encompassing emotional resonance, situational creation, team collaboration, environment building, and technological application. This aimed to provide palliative care patients with comprehensive and continuous psychological intervention by optimizing doctor-patient interaction, strengthening emotional connection, improving physical environment, and utilizing information technology, thereby contributing to alleviating the psychological distress patients confront in the terminal stage and improving their life dignity and quality of life.

The thyroid gland is the largest endocrine organ in the human body, and its dysfunction can cause varying degrees of liver injury, leading to liver failure in severe cases. Patients with hyperthyroidism have a relatively high incidence rate of liver dysfunction, manifesting as hepatocellular injury or cholestatic liver injury, while hypothyroidism is closely associated with metabolic dysfunction-associated fatty liver disease. Autoimmune thyroid diseases, including Hashimoto’s thyroiditis and subacute thyroiditis, are commonly comorbid with autoimmune liver disease. In addition, medications such as antithyroid drugs, amiodarone, and immune checkpoint inhibitors can cause severe liver injury through direct toxicity or immune-mediated mechanisms. Although significant progress has been achieved in related diagnosis and treatment techniques in recent years, there are still many challenges in pathogenesis, individualized treatment strategies, early warning, and prognostic evaluation. This article systematically reviews the research advances in liver injury associated with thyroid dysfunction and proposes the directions for future research, in order to provide guidance for clinical diagnosis and treatment.

ObjectiveTo investigate the molecular mechanisms by which Wenyang Jiedu granules (WYJD) alleviate influenza A virus (IAV)-induced pneumonia based on single-cell transcriptome sequencing. MethodsThirty female BALB/c mice were randomly divided into a blank control group (Control), IAV group, and WYJD low-, medium-, and high-dose groups (WYJD-L, WYJD-M, WYJD-H; 2.925, 5.85, 11.7 g·kg-1, n=6). Except for the Control group, all other groups were intranasally inoculated with IAV subtype H1N1 (A/PR/8/34) to establish an infection model. Two hours after modeling, drug administration was initiated and continued for 5 consecutive days, with daily monitoring of body weight and general condition. On day 6, mice were sacrificed and samples were collected. Lung index was calculated, and histopathological examination of lung tissue was performed. Lung tissues from the Control, IAV, and WYJD-H groups were subjected to single-cell transcriptome sequencing (n=3), focusing on type I alveolar epithelial cells (AT1) to analyze changes in gene expression and signaling pathways. Western blot was used to detect the expression changes of relevant proteins to validate the single-cell sequencing results. ResultsCompared with the Control group, the IAV group exhibited significantly decreased body weight (P<0.05) and significantly increased lung index (P<0.05). Compared with the IAV group, all WYJD-treated groups exhibited significantly increased body weight (P<0.01) and significantly decreased lung index (P<0.01). Single-cell sequencing analysis revealed that WYJD inhibited overactivation of interferon and inflammatory signaling pathways in AT1 cells after IAV infection, including interferon-γ response, interferon-α response, tumor necrosis factor-α/nuclear factor-κB (TNF-α/NF-κB), and interleukin-6/Janus kinase/signal transducer and activator of transcription 3 (IL-6/JAK/STAT3) pathways. Compared with the Control group, the number of AT1 cells in the IAV group showed a decreasing trend. Compared with the IAV group, the WYJD-H group showed an increasing trend, although neither difference was statistically significant. Further analysis of AT1 cell subpopulation gene expression showed that, compared with the Control group, the IAV group exhibited increased expression of pro-apoptotic genes FAS cell surface death receptor (FAS) and cyclin-dependent kinase inhibitor 1A (CDKN1A), a significant increase in tumor protein p53 (Tp53) expression (P<0.05), and significant decreases in expression of the AT1 marker gene advanced glycosylation end-product-specific receptor (AGER) and membrane structural gene caveolin1 (CAV1) (P<0.05, P<0.01). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of FAS, CDKN1A, and Tp53 (P<0.05, P<0.01), and significantly increased expression of AGER and CAV1 (P<0.05, P<0.01). Regarding interferon response-related genes, compared with the Control group, the IAV group showed increased expression of interferon-stimulated gene 15 (ISG15), interferon-induced protein with tetratricopeptide repeats 3 (IFIT3), signal transducer and activator of transcription 2 (STAT2), bone marrow stromal cell antigen 2 (BST2), and C-X-C motif chemokine ligand 10 (CXCL10), with a significant increase in 2′,5′-oligoadenylate synthetase-like protein 1 (OASL1) (P<0.05). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of all the above genes, with highly significant differences for ISG15, IFIT3, STAT2, BST2, and OASL1 (P<0.01), and a significant difference for CXCL10 (P<0.05). Among inflammation-related genes, compared with the Control group, the IAV group showed significantly increased expression of intercellular adhesion molecule 1 (ICAM1), tumor necrosis factor alpha-induced protein 3 (TNFAIP3), keratin 8 (KRT8), tumor necrosis factor receptor superfamily member 1A (TNFRSF1A), and TNFRSF1B (P<0.01), and increased expression of NFKBIA, a negative regulator of NF-κB (P<0.05). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of KRT8 and TNFRSF1B (P<0.05), while ICAM1, NFKBIA, TNFAIP3, and TNFRSF1A showed decreasing trends without statistical significance. Western blot validation showed that, compared with the Control group, protein expression levels of ISG15, FAS, p53, and phosphorylated p65 (p-p65) in lung tissue of the IAV group were significantly increased (P<0.05, P<0.01). Compared with the IAV group, the WYJD-H group showed significantly decreased expression of these proteins (P<0.05, P<0.01). ConclusionWYJD may alleviate viral pneumonia by targeting gene expression in AT1 cells, inhibiting overactivated interferon and inflammatory signaling pathways after IAV infection, and downregulating pro-apoptotic signaling, thereby reducing alveolar epithelial injury.

AIM: To investigate the association between dyslipidemia and macular hard exudates(HEs)in non-proliferative diabetic retinopathy(NPDR)secondary to type 2 diabetes mellitus(T2DM).METHODS: NPDR patients attending the outpatient ophthalmology clinic from January 2021 to December 2023 were selected and divided into three groups according to the severity of macular HEs. Group A: None or minimal HEs; Group B: Definite HEs; Group C: Prominent HEs. Total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), high-density lipoprotein cholesterol(HDL-C), lipoprotein(a)[Lp(a)] levels and other lipid-related indicators were routinely measured. The correlation between these indicators and HEs was analyzed.RESULTS:Group A(24 eyes)consisted of 9 males and 15 females with the mean age of 54.71±6.15 y, group B(52 eyes)consisted of 20 males and 32 females with the mean age of 55.08±6.27 y, group C(14 eyes)consisted of 9 males and 5 females with the mean age of 53.93±6.08 y. The concentration of TC, TG, LDL-C and Lp(a)was highest in group C, followed by group B and lowest in group A with statistically significant differences(P<0.001). There were no statistically significant differences between the three groups for fasting plasma glucose(FPG), glycated hemoglobin A1c(HbA1c), creatinine(Cr), and HDL-C(P>0.05). The results of multivariate Logistic regression analysis showed that elevated levels of TC, TG, LDL-C, and Lp(a)were associated with the presence of macular HEs. Receiver operating characteristiccurve analysis showed that the area under the curve(AUC)for TC, TG, LDL-C, Lp(a), and their combination in predicting macular HEs in NPDR were 0.785, 0.718, 0.784, 0.742, and 0.911, respectively, with the combined model demonstrating the highest predictive performance.CONCLUSION: Dyslipidemia is closely associated with the development and progression of macular HEs in patients with NPDR and T2DM. The levels of TC, TG, LDL-C, and Lp(a)were correlated with the severity of macular HEs, suggesting that dyslipidemia may be involved in the pathological process of macular HEs formation.

Objective:To design a vest-type breast dressing bra and explore its application effect in the external application of traditional Chinese medicine therapy for patients with granulomatous lobular mastitis(GLM).Methods:A randomized controlled study was conducted, utilizing convenience sampling to select female patients with 122 GLM who underwent their first topical medication treatment in the Breast Department of Guangdong Provincial Hospital of Traditional Chinese Medicine between January and May 2023. The patients were divided into a control group and an observation group, with 61 patients in each, using a random number table. Following medication application, patients in the control group used a regular sports bra to secure the medication, while patients in the observation group used a custom-designed vest-style breast medication bra for the same purpose. Three hours after the intervention, comparisons were made between the two groups in terms of the incidence of medication detachment, medication displacement, clothing contamination, patient satisfaction, and safety.Results:Both groups of patients completed the study. The age of the observation group was (32.18 ± 5.50) years old, while the age of the control group was (33.66 ± 5.20) years old. Three hours after the intervention, the incidence of medication detachment, medication displacement, clothing contamination in the observation group were 3.28% (2/61), 6.56% (4/61), and 8.20% (5/61), which were lower than those in the control group with 18.03% (11/61), 26.23% (16/61), and 67.21% (41/61), respectively. The differences were statistically significant ( χ2=6.97, 8.61, 45.23; all P<0.05). The satisfaction level of patients towards the bra in the observation group was (4.43 ± 0.85) points, higher than that of the control group (3.85 ± 1.08) points, with a statistically significant difference ( t=3.30, P<0.05). The incidence rates of skin allergic reactions were 3.28%(2/61) and 4.92%(3/61) in the observation group and the control group, respectively, with no statistically significant difference ( P>0.05). Conclusions:The vest-type breast dressing bra designed in this study can properly secure the medicinal paste, reduce the rate of medication detachment, medication displacement, clothing contamination, and enhance patient satisfaction. It facilitates the external application of traditional Chinese medicine for patients with GLM and is worthy of clinical promotion.

Objective:
To explore the influencing factors and pathways of suicidal ideation among children and adolescents with severe autism spectrum disorder (ASD), so as to provide references for clarifying the impact intensity and pathways of various factors on suicidal ideation in the population.
Methods:
A cross sectional study was conducted from June 17, 2024, to January 12, 2025, involving 96 severely affected ASD children and adolescents aged 8-18 years from Tianjin. Participants were assessed using the Puberty Development Scale (PDS), Children s Alexithymia Measure (CAM), Strengths and Difficulties Questionnaire (SDQ), and Positive and Negative Suicide Ideation (PANSI). The random forest Boruta algorithm was employed to screen core variables, and a Bayesian network model was constructed to analyze the influencing factors of suicidal ideation in children and adolescents with severe ASD.
Results:
Through the screening using the Boruta algorithm, the SDQ scale score, conduct problems, hyperactivity, peer relationship problems and prosocial behavior were identified as the key predictors of suicidal ideation. A Bayesian network model was established with hyperactivity as the central mediating node. The impact of hyperactivity on suicidal ideation exhibited a non linear relationship: compared to the normal state (31.6%, 68.4%), the borderline state of hyperactivity was associated with a higher probability of low risk suicidal ideation (47.1%) and a lower probability of high risk suicidal ideation (52.9%). Suicidal ideation among children and adolescents with severe ASD was closely related to hyperactivity. In the state of hyperactivity, the abnormal peer relationship (95.2%) and the abnormal prosocial behavior (77.0%) were aggravated.
Conclusions
Suicide ideation among children and adolescents with severe ASD is strongly associated with hyperactivity traits. It is necessary to establish a prevention and control system centered on hyperactivity intervention to reduce this risk.

Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

OBJECTIVES:
To investigate the ethnic origin of Chuanqing people, one of the largest unidentified ethnic groups in Guizhou, China, and analyze its genetic relationships with surrounding populations.
METHODS:
Based on a self-developed microhaplotype system, we conducted genotyping and analyzed the genetic distribution of microhaplotype loci and their forensic applicability in Chuanqing population in Guizhou Province. Using the microhaplotype data from different intercontinental populations and previously reported data from Han population living in Guizhou Province, we systematically investigated the genetic background of Chuanqing people through population genetic approaches, including genetic distance estimation, principal component analysis, and phylogenetic tree construction.
RESULTS:
Among the studied population, the number of haplotype per microhaplotype ranged from 6 to 25. The average expected heterozygosity (He), observed heterozygosity (Ho), power of discrimination (PD), and probability of exclusion (PE) were 0.8291, 0.8301, 0.9387, and 0.6593, respectively. The cumulative power of discrimination (CPD) and cumulative probability of exclusion (CPE) for these 33 loci were 1-2.62×10-41 and 1-7.64×10-17, respectively. Population genetic analyses revealed that the Chuanqing population had close genetic relationships with the East Asian populations, especially the local Guizhou Han population, Beijing Han population and the Han populations living in southern China.
CONCLUSIONS
The 33 microhaplotypes exhibit high levels of genetic diversity in the Guizhou Chuanqing population, highlighting their potentials for both forensic identification and parentage testing. The Han populations might have contributed a significant amount of genetic material to the Chuanqing population during the formation and development of the latter.
