BACKGROUND:How to repair bone defect has been a clinical problem for a long time.The effective ingredients of traditional Chinese medicine have good biological activity and therapeutic effect,and the combination of effective ingredients of traditional Chinese medicine and tissue engineering materials has a broad prospect in the field of bone repair.The combination of different effective ingredients of traditional Chinese medicine and scaffolds has similarities in their functional relationships. OBJECTIVE:To collect the cases of the combinations of effective ingredients of traditional Chinese medicine and scaffolds,then analogize tissue engineering scaffolds and effective ingredients of traditional Chinese medicine into two types of traditional Chinese medicine that generate compatibility relationships based on the inspiration of the compatibility of seven emotions and summarize the relationship between the two based on their functional relationships. METHODS:Relevant articles from January 1998 to January 2024 were searched in PubMed and China National Knowledge Infrastructure(CNKI),using English search terms"traditional Chinese medicine,Chinese medicine,traditional Chinese medicine monomers,bone defect,bone repair,bone tissue engineering,tissue engineering,scaffold"and Chinese search terms"traditional Chinese medicine,effective ingredients of traditional Chinese medicine,traditional Chinese medicine monomers,bone tissue engineering,bone tissue engineering scaffold,scaffold,tissue engineering,bone defect,bone repair."A total of 88 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)Both tissue engineering scaffold materials and active ingredients of traditional Chinese medicine have been widely used in the field of bone repair.Although they have obvious advantages in osteogenesis,there are still many shortcomings.Many studies are dedicated to preparing composite materials from the two,hoping to exert a detoxification and synergism through the interaction between the two.(2)Some drugs and materials can promote each other in osteogenesis,antibacterial,and promoting angiogenesis,enhancing their original effects.Inspired by the traditional concept of prescription compatibility,this article summarized it as a"Mutual promotion"relationship and provided examples to support it.(3)Some drugs can enhance the strength of materials,while some materials can achieve sustained release and controlled release effects,increase drug loading and stability,or achieve targeted delivery of drugs loaded on them.The article summarized this unilateral enhancement effect as a"Mutual assistance"relationship.(4)The combination of some traditional Chinese medicine and materials can reduce the toxic side effects of the other party.The article summarizes this detoxification relationship as"Mutual restraint and detoxification."(5)The article provided a new perspective on traditional Chinese medicine composite scaffolds,inspired by the seven emotions compatibility relationship and based on the classification of action relationships.It introduced traditional Chinese medicine concepts into the field of tissue engineering,providing new research ideas for subsequent researchers of composite scaffolds,and providing certain convenience in material selection and matching.

The Korean Journal of Internal Medicine 2025;40(2):243-250
Background/Aims:
Portal vein thrombosis (PVT) frequently occurs in patients with inflammatory bowel disease (IBD), particularly when influenced by factors such as abdominal infections, IBD flare-ups, or surgical procedures. The implications of PVT range from immediate issues such as intestinal ischemia to long-term concerns including portal hypertension and its complications. However, there is a notable gap in comprehensive studies on PVT in IBD, especially with the increasing incidence of IBD in Asia. This research aimed to evaluate the clinical features and outcomes of PVT in patients with IBD at a leading hospital in South Korea.
Methods:
This retrospective analysis reviewed adult patients diagnosed with both IBD and PVT from 1989 to 2021 at a renowned South Korean medical center. The study focused on patient characteristics, specifics of PVT, administered treatments, and outcomes, all confirmed through enhanced CT scans.
Results:
A total of 78 patients met the study’s criteria. Notably, only 20.5% (16/78) were treated with oral anticoagulants; however, a vast majority (96.2%; 75/78) achieved complete radiographic resolution (CRR). When comparing patients receiving anticoagulants to those who did not, a significant preference for anticoagulant use was observed in cases where the main portal vein was affected, as opposed to just the left or right veins (p = 0.006). However, multivariable analysis indicated that neither anticoagulant use nor previous surgeries significantly impacted CRR.
Conclusions
Patients with IBD and PVT generally had favorable outcomes, regardless of anticoagulant use.

Palliative care is a way to help end-of-life populations improve their quality of life, and its development in practice cannot be separated from the level of education in palliative care. At present, some medical schools in palliative care education compared with western developed countries have problems such as imperfect construction of hospice curriculum system, lack of medical students’ hospice knowledge; insufficient interdisciplinary teaching faculty, weak palliative care awareness of medical students; single teaching evaluation mode; weak palliative care practice teaching links. To this end, it is necessary to improve the palliative care curriculum system, explore rich and diverse teaching methods; strengthen interdisciplinary teaching and faculty development, enhancing the awareness of palliative care among medical students;establish a scientific and effective evaluation method, carry out multi-dimensional dynamic assessment; expand the palliative care practice teaching base, and accurately improve the practical skills of medical students in palliative care, and other countermeasures to improve the level of palliative care education, and to help the strategy of Healthy China.

Psoriasis is a chronic inflammatory skin disease with a polygenic genetic background. Its etiology remains unclear, and its pathogenesis is complex and refractory, collectively posing significant challenges in its treatment and greatly affecting the physical and mental health of patients. With the advantages of multi-target and multi-pathway treatment, traditional Chinese medicine has shown unique efficacy and value in the diagnosis and treatment of psoriasis. Modern doctors have a lot of discussion on psoriasis, and most of them tend to treat the disease by solving disorders of the blood system. They think that the disease is closely related to the "heat in the blood". Combining the clinical characteristics and accompanying symptoms of psoriasis, this article traced the causes of "heat in the blood" in psoriasis and believed that multiple internal and external factors have prevented the smooth circulation of Qi. Yang Qi Fuyu (stagnation) and transformation into heat and toxicity is the source of "heat in the blood" in psoriasis. Furthermore, it was proposed that "Fuyu" is the core pathogenesis of psoriasis. The etiology of "Fuyu" is complex, such as external wind and cold pathogens, emotional injuries, internal accumulation of dampness, and deficiency of healthy Qi, all of which can disrupt the ascending and descending movement of Qi, impede the circulation of Qi and fluids, close the pores and skin texture, and subsequently lead to stagnation. Based on the above understanding, "resolving stagnation" is crucial for treating the disease. Many doctors have explored the treatment ideas of psoriasis from the perspectives of dispelling wind, warming cold, regulating Qi, eliminating dampness, tonifying deficiency, and external treatment, aiming to remove the causes, promote the circulation of Qi and fluids, and resolve stagnation and heat. Clinical studies have shown that the therapies can relieve clinical symptoms, reduce recurrence rate, and improve quality of life, which also have good safety in the treatment of psoriasis. This article discussed the treatment of psoriasis from the perspective of "Fuyu", enriching the understanding of TCM regarding the etiology and pathogenesis of psoriasis. It is aiming to serve as an effective supplement to the "treating by solving disorders of the blood system" approach and provide a reference for clinical diagnosis and treatment of psoriasis.

ObjectiveTo explore the effects of Kaixuan Jiedu core prescription (KXJD) on sphingolipid metabolism in the mouse model of imiquimod-induced psoriasis-like skin lesions. MethodsThirty-seven male C57BL/6J mice were randomly assigned into five groups: healthy control (n=11), model (n=11), methotrexate (MTX, n=5), low-dose (15.21 g·kg-1) KXJD (n=5), and high-dose (30.42 g·kg-1) KXJD (n=5). Psoriasis-like skin lesions were induced in mice with 62.5 mg 5% imiquimod cream applied on the back. The KXJD groups and MTX group were treated with 0.2 mL corresponding decoction and MTX, respectively, by gavage daily, while the other groups were given an equal volume of normal saline by the same way. After 5 days of treatment, back skin lesions were collected. Firstly, healthy control and model mice were selected for tandem mass tag (TMT) quantitative proteomics (control vs model=3 vs 3) and targeted lipid metabolomics (control vs model=11 vs 11). Then, the binding degree between core components and target proteins was predicted via network pharmacology and molecular docking. Finally, an animal experiment was performed to decipher the specific regulation mechanism of KXJD on sphingolipid metabolism. Immunohistochemistry was employed to determine the expression level of sphingosine-1-phosphate (S1P), and Western blot was employed to determine the expression levels of sphingosine kinase 2 (SPHK2) and monocyte chemotactic protein-1 (MCP-1). ResultsTMT proteomics and targeted lipid metabolomics suggested that sphingolipid metabolism was active in the psoriatic skin, and key proteases [serine palmitoyltransferase, long chain base subunit 2 (SPTLC2), SPHK2, delta(4)-desaturase sphingolipid 1 (Degs1), and ceramide synthase 4 (CerS4)] and 8 sphingolipid metabolites (including ceramides, sphingol, sphingomyelin, and glycosphingolipid) expressed abnormally (P<0.05) compared with those in the healthy skin. The molecular docking results indicated that the binding energy between the active components (quercetin, kaempferol, and luteolin) in KXJD and key proteins involved in sphingolipid metabolism was less than-8 kal·mol-1. Further experimental verification showed elevated expression levels of SPHK2, S1P, and MCP-1 in psoriatic skin compared with healthy skin (P<0.05), and KXJD down-regulated the expression levels of SPHK2, S1P, and MCP-1 compared with the model group (P<0.05). ConclusionThis study indicates that there is an imbalance in sphingolipid metabolism in psoriatic skin lesions. KXJD may reduce psoriasis-like lesions in mice by regulating sphingolipid metabolism via the SPHK2/S1P/MCP-1 pathway.

ObjectiveTo use bioinformatics technology to screen the molecular patterns and diagnostic biomarkers of ferroptosis closely related to psoriasis, observe the therapeutic effect of Kaixuan Jiedu core prescription on psoriasis and explore its potential mechanism through animal experiments. MethodsPsoriasis microarray data from GEO were analyzed to identify differentially expressed genes (DEGs). Intersection with a ferroptosis gene set yielded psoriasis ferroptosis-related genes (FRGs), which underwent correlation, consensus clustering, enrichment, and immune infiltration analyses. Core diagnostic FRGs (Hub-FRGs) were identified using random forest (RF), support vector machine (SVM), LASSO regression, Nomogram, and ROC analyses. In vivo, imiquimod (5% cream) induced psoriasis in mice (except controls). Drug treatment groups received respective doses, while control and model groups received saline via daily gavage for 7 days. Back skin changes were recorded and PASI scored. Hematoxylin-eosin (HE) staining assessed histopathology. The levels of ferrous ion (Fe2+), malondialdehyde (MDA), 4-hydroxynonenal (4-HNE) and free fatty acid (FFA) in skin tissue were detected. The level of reactive oxygen species (ROS) in skin tissue was detected by immunofluorescence. Immunohistochemistry was used to detect the expression of ChaC glutathione-specific γ-glutamyl transferase 1 (CHAC1), arachidonic acid 12-lipoxygenase β (ALOX12B), trimotif protein 21 (TRIM21), proliferation marker (Ki67) and nuclear transcription factor-κB (NF-κB) protein. ResultsAnalysis of GSE30999 identified 2 100 DEGs and 24 FRGs. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment revealed 1 000 biological functions and 75 pathways. After cluster analysis, combined with three machine learning algorithms, Nomogram and ROC curve analysis, the core Hub-FRGs (CHAC1, ALOX12 B, TRIM21) were obtained. Immunoinfiltration showed inactive memory CD4+T cells and activated dendritic cells abundance significantly correlated with Hub-FRGs. In vivo, model group vs. control showed significantly increased PASI/Baker scores (P<0.05), epidermal hyperkeratosis, inflammatory infiltration, and elevated levels of Fe2+, MDA, 4-HNE, FFA, ROS, CHAC1, ALOX12B, TRIM21, Ki67, and NF-κB (P<0.05). Drug groups vs. model group exhibited significantly reduced scores (P<0.05), alleviated skin lesions, and decreased levels of Fe2+, MDA, 4-HNE, FFA, ROS, Hub-FRGs, Ki67, and NF-κB (P<0.05). ConclusionKaixuan Jiedu core prescription can significantly improve the skin pathological injury of psoriasis mice, showing good therapeutic and repair effects, and its mechanism may be related to regulating the expression of ferroptosis genes CHAC1, ALOX12B and TRIM21, which are closely related to the pathogenesis of psoriasis.

ObjectiveTo investigate the efficacy and safety of Kaixuan Jiedu compatibility and the decomposed prescriptions in the treatment of psoriasis. MethodsThirty Balb/c mice were randomly grouped as follows (n=6): normal, model, Kaixuan Jiedu (KXJD, 15.21 g·kg-1), Kaixuan (KX, 3.08 g·kg-1), and Jiedu (JD, 12.13 g·kg-1). Except the normal group, the rest groups were modeled for psoriasis-like skin lesions by topical application of imiquimod, and samples were collected after 7 days of continuous intervention. Mice were photographed at the lesion site during modeling and before sampling and the psoriasis area and severity index (PASI) was calculated. Hematoxylin-eosin (HE) staining was used to observe pathological changes in the lesions and measure the epidermal thickness. Mice were photographed and observed for the tortuous dilation of dermal capillaries. The expression of vascular endothelial growth factor (VEGF), platelet-endothelial cell adhesion molecule (CD31), proliferating cell nuclear antigen (Ki67), and cytokeratin 10 (CK10) in the epidermal tissue was detected by immunohistochemistry. Immunofluorescence assay was employed to determine the expression of Claudin-1 and Occludin. Real-time PCR was employed to determine the mRNA levels of interleukin-17A (IL-17A) and interleukin-23 (IL-23). The spleen and thymus were photographed and weighed, and the spleen and thymus indices were calculated. The safety of the treatment was assessed by automatic biochemistry testing of the serum, liver, and kidney functions and by HE staining of the liver, kidney and spleen. ResultsCompared with that of the normal group, the skin of the model group showed erythema, infiltration, and typical psoriasis-like changes, tortuous dilation of dermal capillaries, hyperkeratosis in epidermal cells, acanthosis, massive lymphocytic infiltration in the dermis, impaired barrier function, increased expression of VEGF, CD31, Ki67, and CK10 (P<0.01), reduced expression of Claudin-1 and Occludin (P<0.01) in the epidermis, and up-regulated mRNA levels of IL-17A and IL-23 (P<0.01). In addition, the mice in the model group showed spleen enlargement, thymus atrophy, increased spleen index, and decreased thymus index (P<0.01). Compared with the model group, KXJD and JD reduced psoriasis-like skin lesions, inhibited the tortuous dilation of dermal capillaries, reduced the expression of VEGF, CD31, Ki67, and CK10 (P<0.01), increased the expression of claudin-1 (P<0.01), and down-regulated the mRNA levels of inflammatory factors (P<0.01). Moreover, the KXJD group outperformed the JD group. The JD group showed no significant difference from the model group regarding the spleen index, thymus index, and Occludin expression. The psoriasis indicators in the KX group were not significantly different from those in the model group. ConclusionKXJD and JD can reduce the symptoms of local skin lesions of psoriasis, which is manifested as different inhibition degrees of the proliferation and differentiation of keratin-forming cells, tortuous dilation of dermal capillaries, and inflammatory reactions, as well as the protection of the skin barrier. Moreover, KXJD outperformed JD. KX alone did not significantly reduce psoriasis lesions in mice. KXJD and the decomposed prescriptions are safe and effective, causing no obvious liver and kidney injuries.

ObjectiveTo investigate the target proteins directly bound by neochlorogenic acid (NA) and the molecular mechanisms that ameliorate the proliferation and inflammatory response of psoriatic keratinocytes. MethodsM5-induced HaCaT cells were used as a psoriatic keratinocyte proliferation and inflammatory cell model. The synthesized NA probe (NA-P) and NA prodrug were first evaluated for cell viability using a cell proliferation/cell counting kit-8(CCK-8). The potency of NA and NA-P was evaluated in the safe concentration range, and the effects of 0-100 μmol·L-1 NA and probe on M5-induced proliferation of HaCaT cells were detected using CCK-8. The effects of 20, 40, 80 μmol·L-1 NA and 80 μmol·L-1 NA-P on the expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-23 (IL-23), and interleukin-17A (IL-17A) inflammatory factors were detected by enzyme-linked immunosorbent assay (ELISA), and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to measure the effects of NA on the mRNA expression of keratin 16 (K16) in HaCaT cells, S100 calcium-binding protein A9 (S100A9), S100 calcium-binding protein A7 (S100A7), IL-6, IL-17A, and chemokine 1 (CXCL1). In vitro fluorescence labeling and competition experiments using NA-P were performed, and target protein angling and analysis using pull-down experiments combined with liquid chromatography-mass spectrometry (Pull-down/LC-MS/MS) were conducted. Target validation was performed using pull-down experiments combined with protein immunoblotting (Pull down-WB), cellular heat transfer analysis combined with protein immunoblot (CETSA-WB) experiments, and molecular docking. Finally, Real-time PCR was utilized to detect the effects of 20, 40, 80 μmol·L-1 NA and 80 μmol·L-1 NA-P on the mRNA expression of IL-1β, nucleotide-binding oligomeric structural domain-like receptor protein 3 (NLRP3), apoptosis-associated speckled-like protein (ASC), and cysteine protease-1 (Caspase-1) in HaCaT cells. Protein immunoblot (Western blot) was used to detect the effects of phosphorylated p65 (p-p65), p65, phosphorylated human nuclear factor-κB inhibitory protein α (p-IκBα), human nuclear factor κB inhibitory protein α (IκBα), and heat shock protein 90 (HSP90) expression. ResultsIn the 200 μmol·L-1 safe concentration range, HaCaT cell proliferation, increased expression of TNF-α, IL-1β, IL-23, and IL-17A inflammatory factors, and increased mRNA expression of K16, S100A9, S100A7, IL-6, IL-17A, and CXCL1 were observed in the M5 group compared with the blank group. Cell proliferation in 5-100 μmol·L-1 NA and NA-P groups was inhibited, and the expression of TNF-α, IL-1β, IL-23, and IL-17A inflammatory factors was decreased in the NA-L, NA-M, NA-H, and NA-P-H groups. The mRNA expression of K16, S100A9, S100A7, IL-6, IL-17A, and CXCL1 was decreased (P<0.05). High-confidence targets were screened for HSP90 protein by Pull-down/LC-MS/MS using 200 μmol·L-1 NA competing with 100 μmol·L-1 NA-P. Compared with that in the blank group, the mRNA expression of NLRP3, IL-1β, ASC, and Caspase-1, as well as the expression of p-p65/p65, p-IκBα/IκBα, and HSP90 protein, were increased in HaCaT cells in the M5 group (P<0.05). Compared with that in the M5 group, the mRNA expression of NLRP3, IL-1β, ASC, and Caspase-1 of cells in the NA-L group, the NA-M group, the NA-H group, and the NA-P-H group was decreased (P<0.05). p-p65/p65 and p-IκBα/IκBα were decreased in the NA-M and NA-H groups (P<0.05), and there was no change in HSP90 protein. Pull down-WB showed that NA could directly target HSP90 protein, and NA binding to HSP90 protein enhanced its thermal stability. Molecular docking of NA with HSP90 family proteins HSP90AA1, HSP90B1, and HSP90AB1 all resulted in highly stable binding. ConclusionNA can inhibit the proliferation and inflammatory response of psoriatic keratinocytes by a mechanism that may be achieved by targeting HSP90 to modulate the NF-κB/NLRP3 signaling pathway.
