In recent years, there have been frequent adverse reactions/events associated with traditional Chinese medicine(TCM), especially liver injury related to traditional non-toxic TCM, which requires adequate attention. Liver injury related to traditional non-toxic TCM is characterized by its sporadic and insidious nature and is influenced by various factors, making its detection and identification challenging. There is an urgent need to develop a strategy and method for early detection and recognition of traditional non-toxic TCM-related liver injury. This study was based on national adverse drug reaction monitoring center big data, integrating methodologies such as reporting odds ratio(ROR), network toxicology, and computational chemistry, so as to systematically research the risk signal identification and evaluation methods for TCM-related liver injury. The optimized ROR method was used to discover potential TCM with a risk of liver injury, and network toxicology and computational chemistry were used to identify potentially high-risk TCM. Additionally, typical clinical cases were analyzed for confirmation. An integrated strategy of "discovery via big data, identification via dry/wet method, confirmation via typical cases, and precise risk prevention and control" was developed to identify the risk of TCM-related liver injury. Corydalis Rhizoma was identified as a TCM with high risk, and its toxicity-related substances and potential toxicity mechanisms were analyzed. The results revealed that liver injury is associated with components such as tetrahydropalmatine and tetrahydroberberine, with potential mechanisms related to immune-inflammatory pathways such as the tumor necrosis factor signaling pathway, interleukin-17 signaling pathway, and Th17 cell differentiation. This paper innovatively integrated real-world evidence and computational toxicology methods, offering insights and technical support for establishing a risk discovery and identification strategy for TCM-related liver injury based on real-world big data, providing innovative ideas and strategies for guiding the safe and rational use of medication in clinical practices.

Objective:Based on bioinformatics analysis, this study aimed to identify the complement component 5a receptor 1(C5aR1)and chemokine C-C motif ligand-2(CCL2)genes in vascular dementia(VaD)and to explore the expression and clinical significance of serum C5aR1 and CCL2 levels in VaD patients.Methods:The GSE122063 dataset was selected from the Gene Expression Omnibus(GEO)database to screen for consistently differentially expressed genes in the frontal and temporal lobes of VaD patients and non-dementia patients.The Matascape database was used to analyze the functions and pathways of differentially expressed genes, and the STRING network and Cytoscape software were used to identify key genes.In this case-control study, 53 VaD patients seeking care at the Department of Neurology of the Affiliated Hospital of Jiangsu University between January 2022 and December 2022 were included in the VaD group, and 50 non-dementia individuals were included in the control group.General information, Montreal Cognitive Assessment(MoCA)scores, Mini-Mental State Examination(MMSE)scores, and scores of the total cerebral small vessel disease(CSVD)burden were collected for both groups, and serum C5aR1 and CCL2 expression was detected.The correlation of serum C5aR1 and CCL2 levels with MoCA scores, MMSE scores, and scores of the total CSVD burden in the VaD group was analyzed.Receiver operating characteristic(ROC)curve analysis was used to assess the diagnostic value of serum C5aR1 and CCL2 levels in VaD.Results:In the GSE122063 dataset, compared with non-dementia patients, there were 43 upregulated genes and 63 downregulated genes simultaneously in the frontal and temporal lobes in the VaD group.After importing 106 genes into the Cytoscape software and using the Stress and Betweenness algorithms in the cytoHubba plugin, two key genes, C5aR1 and CCL2, were identified.Serum levels of C5aR1[(57.25±10.34)μg/L vs.(43.26±8.24)μg/L, t=7.607, P<0.001]and CCL2[(210.42±42.19)ng/L vs.(151.73±36.04)ng/L, t=7.570, P<0.001]in the VaD group were higher than those in the control group.Serum levels of C5aR1 and CCL2 were negatively correlated with MoCA scores( r=-0.691, -0.668, P<0.001)and MMSE scores( r=-0.736, -0.729, P<0.001), and positively correlated with scores of the total CSVD burden( r=0.598, 0.582, P<0.001).The areas under the ROC curve for serum C5aR1 and CCL2 levels in diagnosing VaD was 0.838 and 0.845, respectively.The area under the ROC curve with the combination of C5aR1 and CCL2 for the diagnosis of VaD was 0.896. Conclusions:Serum levels of C5aR1 and CCL2 are elevated in VaD patients and closely related to their cognitive function and the total CSVD burden, and may be used as an auxiliary diagnostic tool for VaD patients.

Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Aim To investigate the effects of Cartham-us tinctorius L.extract(CTLE)on oxidative stress,lipid metabolism,and apoptosis levels of mice with al-cohol-induced liver injury and its mechanism of action.Methods The mouse model of alcohol-associated liver disease was established by chronic alcohol feeding and acute alcohol gavage.Mice were randomly divided into four groups.During the modeling period,the state changes of mice were observed every day,and their weight was recorded.At the end of modeling,blood and liver tissues were collected from each group of mice.The blood of mice was analyzed biochemically,and HE staining and Oil Red O staining were used to evaluate further the degree of pathological damage in the liver of mice.Quantitative real-time PCR(qPCR)and Western blot were applied to detect the mRNA and protein expression levels of p-PI3K,PI3K,p-Akt,Akt,p-mTOR,mTOR,p-FoxO1,FoxO1,p-FoxO3a,FoxO3a,p-FoxO4,FoxO4,BCL and BAX factors.Results Compared to the model group,the CTLE administration group showed improved hepatic patho-logical injury and reduced lipid deposition.The bio-chemical indexes in serum and liver,such as ALT,AST,TG,TC,and MDA levels were reduced,while GSH and SOD levels increased.Regulating the PI3K/Akt/FoxO pathway resulted in increased production of SOD,which reduced damage and apoptosis caused by reactive oxygen species(ROS).Conclusions CTLE can exert anti-oxidative stress and anti-apoptotic effects through the PI3K/Akt/FoxO pathway and attenuates alcoholic liver injury in mice,providing new ideas for the treatment of alcoholic liver disease and the develop-ment of related drugs.

Objective To observe the correlations of chest CT quantitative parameters in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)with blood eosinophil(EOS)level.Methods Chest CT data of 162 AECOPD patients with elevated eosinophils were retrospectively analyzed.The patients were divided into low EOS group(n=105)and high EOS group(n=57)according to the absolute counting of blood EOS.The quantitative CT parameters,including the number of whole lung bronchi and the volume of blood vessels,low-attenuation area percentage(LAA％)of whole lung,of left/right lung and each lobe of lung,as well as the luminal diameter(LD),wall thickness(WT),wall area(WA)and WA percentage of total bronchial cross-section(WA％)of grade 3 to 8 bronchi were compared between groups.Spearman correlations were performed to analyze the correlations of quantitative CT parameters with blood EOS level.Results LAA％of the whole lung,of the left/right lung and each lobe of lung,as well as of the upper lobe of right lung LDgrade4,middle lobe of right lung WTgrade5,upper lobe of right lung WAgrade4,middle lobe of right lung WAgrade5 and lower lobe of left lung WAgrade3 in low EOS group were all higher than those in high EOS group(all P＜0.05).Except for the upper lobe of right lung LDgrade4,the above quantitative CT indexes being significant different between groups were all weakly and negatively correlated with blood EOS level(r=-0.335 to-0.164,all P＜0.05).Conclusion Chest CT quantitative parameters of AECOPD patients were correlated with blood EOS level,among which LAA％,a part of WT and WA were all weakly negatively correlated with blood EOS level.

ObjectiveTo investigate the effect of mucin 1 (MUC1) on the proliferation and apoptosis of nasopharyngeal carcinoma (NPC) and its regulatory mechanism. MethodsThe 60 NPC and paired para-cancer normal tissues were collected from October 2020 to July 2021 in Quanzhou First Hospital. The expression of MUC1 was measured by real-time quantitative PCR (qPCR) in the patients with PNC. The 5-8F and HNE1 cells were transfected with siRNA control (si-control) or siRNA targeting MUC1 (si-MUC1). Cell proliferation was analyzed by cell counting kit-8 and colony formation assay, and apoptosis was analyzed by flow cytometry analysis in the 5-8F and HNE1 cells. The qPCR and ELISA were executed to analyze the levels of TNF-α and IL-6. Western blot was performed to measure the expression of MUC1, NF-кB and apoptosis-related proteins (Bax and Bcl-2). ResultsThe expression of MUC1 was up-regulated in the NPC tissues, and NPC patients with the high MUC1 expression were inclined to EBV infection, growth and metastasis of NPC. Loss of MUC1 restrained malignant features, including the proliferation and apoptosis, downregulated the expression of p-IкB、p-P65 and Bcl-2 and upregulated the expression of Bax in the NPC cells. ConclusionDownregulation of MUC1 restrained biological characteristics of malignancy, including cell proliferation and apoptosis, by inactivating NF-κB signaling pathway in NPC.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.
