Liver cancer is one of the most common malignant tumors in the digestive system and ranks sixth among newly diagnosed malignant tumors worldwide. Transforming growth factor-β (TGF-β) regulates cell differentiation, proliferation, apoptosis, and other physiological and pathological mechanisms and exerts cancer-suppressive and pro-cancerous dual effects in the process of tumor development. In recent years, with the continuous exploration of the mechanism of liver cancer, it has been found that the conversion of the cancer-suppressive effect into a pro-cancerous effect of this pathway plays a key role in the development of liver cancer. Traditional Chinese medicine (TCM) provides a unique perspective for the classification, diagnosis, and treatment of liver cancer with its comprehensive regulatory effects of multi-components, multi-targets, and multi-pathways. This paper summarized that the cancer-suppressive mechanisms of the TGF-β signaling pathway included promoting cancer cell cycle arrest, apoptosis, autophagy, et al, while the pro-cancerous mechanisms included promoting cancer cell proliferation, invasion and metastasis, immunosuppression, angiogenesis, et al. The TCM compounds intervening this pathway were sorted out, including Jianpi Huayu compound, Fuyang Baoyuan compound, Yipi Yanggan compound, Fuzheng Jiedu compound, compound Astragalus and Salvia, Biejia Jianwan, Dahuang Zhechong pill, and Qingxiang powder. The single TCMs mainly included Schizocapsa plantaginea, Dendrobii Caulis, Gleditsia sinensis, and Dracaena cochinchinensis. The active ingredients of TCM are mainly concentrated on flavonoids, alkaloids, glycosides, phenolics, terpenoids, polysaccharides, and other kinds of compounds. At the same time, it summarized that the liver cancer inhibition mechanism of TCM by regulating this pathway mainly included promoting apoptosis of liver cancer cells, blocking the cell cycle, and inhibiting liver cancer cell proliferation, migration, invasion, angiogenesis, immune escape, etc. The mechanism aims to give full play to the advantages of TCM and precisely regulate the TGF-β signal, thereby exerting positive anti-tumor effects, opening up a new direction for the precise targeted treatment of liver cancer, and providing a scientific basis and a new strategy for the application of TCM in the treatment of liver cancer.

Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

Chronic atrophic gastritis (CAG) is a digestive system disease characterized by the reduction and atrophy of the intrinsic glands of the gastric mucosa. This disease is closely related to risk factors such as Helicobacter pylori (Hp) infection,long-term unhealthy eating habits and lifestyle. As CAG is a key link in the development of gastric cancer,effectively preventing its deterioration is of great significance for the prevention of gastric cancer. At present,Western medicine mainly uses symptomatic treatments such as eradicating Hp,protecting gastric mucosa, and promoting gastrointestinal motility. However, long-term use is prone to drug resistance and cannot reverse limitations such as gland atrophy, making it urgent to explore new intervention strategies. In recent years,with the deepening of CAG mechanism research,the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway,as one of the classic signaling pathways,plays a significant role in the occurrence and development of CAG,while its systematic summary is still blank. Based on the regulatory advantages of "multi-target,multi-pathway,and low toxicity",traditional Chinese medicine can improve the pathological process of CAG by intervening in key nodes of the PI3K/Akt pathway. In this paper,the research progress of traditional Chinese medicine regulating PI3K/Akt pathway to improve CAG was systematically reviewed for the first time. The expression of PI3K/Akt signaling pathway in CAG was discussed,including the regulation of inflammation and oxidative stress,cell proliferation and apoptosis,and autophagy. The traditional Chinese medicine flavonoids,alkaloids,terpenoids and other compounds that regulate this pathway were summarized. The traditional Chinese medicine compounds mainly include classic famous prescriptions such as Xiaochaihu Tang,Banxia Xiexin Tang,Morodan concentrated pills,Elian granules and other traditional Chinese patent medicines,as well as empirical prescriptions such as modified Leweiyin formula,and Qiling prescription. This study aims to give full play to the advantages of traditional Chinese medicine and lay a solid foundation for the wide application and further development of CAG treatment,and provide new ideas for clinical research and drug research on CAG.

ObjectiveTo investigate the effect of nicotinamide adenine dinucleotide on vascular endothelial injury in hypertension and its molecular mechanism. MethodsC57BL/6J mice were randomly divided into saline group (Saline) and hypertension group (Ang Ⅱ, which were infused with Ang Ⅱ via subcutaneously implanted osmotic pumps), and supplemented daily with nicotinamide mononucleotide (300 mg/kg), a precursor of NAD+. Blood pressure, endothelial relaxation function and pulse wave velocity were measured after 4 weeks. Wound healing assay and adhesion assay were used to evaluate the function of endothelial cells in vitro. mtROS levels were detected by immunofluorescence staining. RT-PCR was used to detect the mRNA expression of mtDNA, SIRT3 and isocitrate dehydrogenase 2 (IDH2). 8-hydroxy-2'-deoxyguanosine levels were detected by enzyme-linked immunosorbent assay. The protein expression levels of p-eNOS, eNOS, SIRT3 and IDH2 were detected by Western blot. ResultsNMN supplementation reduced blood pressure (P<0.001) and improved endothelial function and arterial stiffness (P<0.001) in hypertensive mice. In vitro, NMN improved endothelial function in AngII-stimulated endothelial cells (P<0.05) and attenuated mitochondrial oxidative stress levels (P<0.001). Mechanistically, NMN elevated SIRT3 activity (P<0.001), which subsequently enhanced IDH activity (P<0.001) and reduced oxidative stress levels in endothelial cells. Conversely, knockdown of IDH2 would reverse the effect of SIRT3 in improving endothelial function (P<0.001). ConclusionNAD+ lowers blood pressure and enhances vascular function in hypertension by reducing the level of oxidative stress in endothelial cells through activation of the SIRT3/IDH2 signal pathway.

Objective To investigate the awareness of radon exposure hazards among non-uranium miners in Chongqing, China. Methods A survey was conducted among 177 male miners from eight non-uranium metal mines in Chongqing to collect data on basic information, personal habits, and the rate of radon awareness. Factors affecting radon awareness were analyzed using chi-square test and logistic regression model. Results The awareness rate of radon among miners was 23.73%. The chi-square test indicated significant difference in the radon awareness rate among miners with different levels of education (χ2 = 10.28, P < 0.05), while there was no significant difference across different ages, years of work, labor relations, job categories, and types of miners (P > 0.05). Binary logistic regression analysis showed that a college (junior college) or higher level of education, a high school level of education, and working in mines were factors affecting the radon awareness among miners (χ2 = 4.030, 9.150, 11.776, P < 0.05). Conclusion Miners lack awareness of radon, and there is an urgent need to strengthen education and propaganda regarding the hazards of radon.

ObjectiveTo investigate the effects of Xijiao Dihuangtang (XJDHT) on mice with sepsis and cellular models of sepsis and explore its molecular mechanism in alleviating sepsis-induced inflammatory responses via regulating pyruvate kinase M2 (PKM2)-mediated one-carbon metabolism pathway. MethodsForty C57BL/6N mice were randomly divided into four groups: normal group, model group, low-dose XJDHT group (7.7 g·kg-1), and high-dose XJDHT group (15.4 g·kg-1). After one week of continuous gavage, sepsis was induced using cecal ligation and puncture (CLP) in groups except the normal group. 24 h after the surgery, mortality rates in all groups were recorded, and serum cytokines were measured by enzyme linked immunosorbent assay (ELISA). Lung histopathology was examined by hematoxylin-eosin (HE) staining. During the in vitro experiment, the human monocytic leukemia cell line (THP-1) was exposed to various concentrations of XJDHT and treated with lipopolysaccharide (LPS) at a final concentration of 2 mg·L-1 for 24 h. Cell apoptosis was detected using terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. Protein levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax) were measured by Western blot. Transcriptome sequencing was performed to analyze differentially expressed genes in all groups and conduct gene ontology (GO) enrichment. Key genes in the one-carbon metabolism pathway, including pyruvate kinase M2 (PKM2), 5-methyltetrahydrofolate-homocysteine methyltransferase (MTR), and phosphoglycerate dehydrogenase (PHGDH), were verified by Western blot. A PKM2 inhibition model was established using shikonin for further protein expression analysis. ResultsAnimal experiments showed that compared with the normal group, the model group exhibited significantly elevated body temperature and lung pathology (P<0.01) and increased serum TNF-α and IL-1β levels (P<0.01). High-dose XJDHT reduced body temperature and lung tissue damage (P<0.01) and significantly decreased serum TNF-α and IL-1β levels (P<0.01). Low-dose XJDHT treatment showed no significant temperature change (P<0.01) but reduced serum TNF-α and IL-1β levels (P<0.01). Transcriptome sequencing and Western blot revealed significant differences in the expression of TNF-α, IL-1β, and one-carbon metabolism genes (PKM2, MTR, and PHGDH) (P<0.01). Cell experiments demonstrated that compared to the normal group, the model group showed elevated protein expressions of TNF-α and IL-1β in THP-1 cells (P<0.01), decreased Bcl-2/Bax ratio, and increased apoptosis (P<0.01). Transcriptome sequencing and Western blot revealed significant differences in the expression of TNF-α, IL-1β, and one-carbon metabolism genes (PKM2, MTR, and PHGDH) (P<0.01). Compared to the model group, high-dose XJDHT significantly increased Bax/Bcl-2 ratio and PHGDH protein expression (P<0.01) and effectively reduced cell apoptosis (P<0.01) while down-regulating protein expressions of TNF-α, IL-1β, PKM2, and MTR (P<0.01). Low-dose XJDHT moderately increased Bax/Bcl-2 ratio and PHGDH protein expression (P<0.05), reduced apoptosis (P<0.05), and decreased IL-1β and MTR protein levels (P<0.05, P<0.01), but there were no significant changes in TNF-α and PKM2 expression. After PKM2 inhibition by shikonin in THP-1 cells, the expression of protein related to one-carbon metabolism was detected. Compared with the blank group, the LPS-induced model group showed significantly upregulated PKM2 and MTR protein expression (P<0.01) and downregulated PHGDH expression (P<0.01). Compared with the model group, shikonin treatment significantly reduced PKM2 expression (P<0.05), increased PHGDH expression (P<0.01), and decreased MTR expression (P<0.05). ConclusionXJDHT can inhibit the release of inflammatory factors in sepsis, and its mechanism is related to the intervention of the PKM2-regulated one-carbon metabolism pathway in macrophages.

BACKGROUND:Multiple studies have confirmed that mitogen-activated protein kinase(MAPK)signaling pathway is involved in cell proliferation,and microRNA(miR)is involved in the occurrence and development of hypertrophic scars.Therefore,the role of miR-27a-3p and MAPK signaling pathways in pathological scar formation has been further explored. OBJECTIVE:To explore the effect of miR-27a-3p on the proliferation of human hypertrophic scar fibroblasts through the MAPK signaling pathway. METHODS:The primary fibroblasts were isolated and collected from the skin samples.The primary fibroblasts were observed by inverted microscope and verified by immunofluorescence.The relative expression level of miR-27a-3p in tissues was detected by qRT-PCR.The target genes of hsa-miR-27a-3p were predicted using the database,and then the predicted target genes were enriched by gene ontology function analysis and biological pathway enrichment analysis of the Kyoto Encyclopedia of Genes and Genomes.There were seven groups:blank control,negative control,miR-27a-3p mimic,miR-27a-3p inhibitor,miR-27a-3p mimic+p38 MAPK inhibitor,miR-27a-3p mimic+extracellular regulated protein kinase inhibitor,miR-27a-3p mimic+c-Jun N-terminal kinase inhibitor.Western blot was used to detect the levels of extracellular regulated protein kinase,c-Jun N-terminal kinase inhibitor.and p38 kinase and their phosphorylation levels.Cell counting kit-8 and EdU were used to detect cell proliferation. RESULTS AND CONCLUSION:Compared with normal skin fibroblasts,hypertrophic scar fibroblasts had stronger proliferative activity(P<0.05)and faster proliferation level(P<0.001).Compared with normal skin,miR-27a-3p was highly expressed in hypertrophic scars(P<0.001).Compared with the negative control group,overexpression of miR-27a-3p could promote cell proliferation activity(P<0.001)and proliferation levels(P<0.001).Compared with the negative control group,knockdown of miR-27a-3p could inhibit the proliferation activity(P<0.05)and proliferation levels(P<0.001).Compared with the negative control group,overexpression of miR-27a-3p promoted the phosphorylated levels of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 mitogen-activated protein kinase(P<0.05).Compared with the negative control group,knockdown of miR-27a-3p inhibited the phosphorylated levels of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 MAPK(P<0.05).Compared with the miR-27a-3p mimic group,specific inhibitors of extracellular regulated protein kinase,c-Jun N-terminal kinase,and p38 MAPK reversed the effects of miR-27a-3p on the proliferative activity(P<0.01)and proliferation level(P<0.001)of fibroblasts.To conclude,these results suggest that miR-27a-3p promotes the proliferation of human hypertrophic scar fibroblasts by activating the MAPK signaling pathway.

Background:
Chronic pain significantly affects daily activities, mental health, and the interpersonal relationships of patients. Consequently, physicians use various treatments to manage pain. This study investigated the perceptions of treatment, accompanying symptoms, and other problems in patients with chronic pain.
Methods:
The authors enrolled patients with chronic pain from 19 university hospitals in South Korea. Data was collected on age, gender, diagnosis, disease duration, severity of pain, perception of pain treatment, and accompanying symptoms or problems using an anonymous survey comprising 19 questions.
Results:
In total, 833 patients with chronic pain completed the survey, and 257 (31.0%) and 537 (64.5%) patientsexpressed concerns about the potential adverse effects of medication and opioid addiction, respectively. Personalitychanges such as irritability or anger were the most frequent accompanying symptoms in 507 (63.8%) patients, followed by depression and sleep disturbance in 462 (58.1%) and 450 (54.5%) patients, respectively. Depression (P = 0.001) and anxiety (P = 0.029) were more common among women, whereas divorce (P = 0.016), family conflict (P < 0.001), unemployment (P < 0.001), suicide attempts (P < 0.001), and restrictions on economic activity (P < 0.001) were more common among men. The frequency of accompanying symptoms, except for suicidal ideation,was higher in the younger patients aged ≤ 40 years than in the older patients aged > 40 years.
Conclusions
Many patients with chronic pain had concerns about adverse effects or medication tolerance and experienced anxiety, depression, or sleep disturbances. The prevalence of accompanying problems varies according to age and gender.
