With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

Screening and evaluating the diseases responding specifically to traditional Chinese medicine （TCM） will help to highlight the advantages of TCM treatment， and the evaluation method should be standardized with consideration to the unique characteristics of the diseases. The incidence of Sjögren's Syndrome （SS） is increasing year by year， while the pathogenesis of this disease remains unclear. Modern therapies for this disease include biological agents and immunosuppressants， which generally have unsatisfactory efficacy. The TCM treatment of SS focuses on the harmony of the physical and mental health. The Rheumatology Branch of the China Association of Chinese Medicine organizes experts in TCM， Western medicine， and evidence-based medicine to form working groups. Delphi method and bibliometric method were used for analysis， and SS was selected as a disease responding specifically to TCM. Furthermore， the evaluation system was established for this disease， and the consensus regarding this disease was reached after seminar discussion. This paper summarized the whole process of the evaluation of the advantages of TCM treatment of SS. First， because TCM atomization is widely used in clinical practice and enriches TCM administration methods， this therapy is included after other non-drug therapies were taken as characteristic therapies. Second， the evaluation indicators of therapeutic effect should be determined with consideration to international acceptance and the current research status. Third， the expression method should be accurate， standardized， and objective， highlight the natural advantages of TCM， and avoid arbitrary extension. This paper provides a reference for clinicians to explore other diseases responding specifically to TCM.

Tripterygium wilfordii is widely used in the treatment of immune system disease and has a remarkable curative effect. Triptolide and Tripterygium glycosides are the most commonly used active ingredients in clinical practice， but their treatment window is narrow and there are many side effects. The damage involves the reproductive system， blood system， cardiovascular system， digestive system， etc. Based on clinical observations and literature summaries， the symptoms of adverse reactions mostly occur in the digestive system （liver and gastrointestinal tract）. Relevant scholars have launched a lot of studies of the manifestations of liver injury induced by T. wilfordii and the mechanism of liver injury. The mechanism is mainly related to liver cell apoptosis， induction of oxidative stress， immune injury， excessive autophagy of liver cells， abnormal fatty acid metabolism， and abnormal enzyme metabolism in liver tissues. This article reviewed and summarized relevant literature on gastrointestinal injury caused by T. wilfordii， but there are few studies on the manifestations and mechanisms of adverse reactions， which still need further research by scholars. In addition， this article also summarized the research on how to reduce toxicity and enhance efficacy of prescriptions prepared from T. wilfordii in the digestive system， mainly involving compatibility with western medicines （Methotrexate， Leflunomide， Iguratimod， etc.）， use along or combination with Chinese medicines （single Chinese medicine， Chinese medicine monomers， and Chinese medicine compounds）， acupuncture and moxibustion （electroacupuncture and moxibustion）， dosage form improvement （glycol plastid gel， self-dissolving microneedle， solid lipid nanoparticles， gastric floating sustained-release capsules， etc.）， processing （steaming， stir-frying， radish seed processing， money grass processing， licorice processing， etc.）， and other methods to reduce toxicity. To sum up， this article analyzed the manifestations， mechanisms， and methods of reducing toxicity and enhancing efficacy of T. wilfordii-induced liver injury and gastrointestinal injury by sorting out relevant literature， in order to provide a reference for the clinical application of T. wilfordii and some research ideas for the future in-depth study of T. wilfordii-induced digestive system injury.

Objective:To analyze the clinical characteristics of progressive pulmonary fibrosis in patients with interstitial lung disease associated with connective tissue disease, identify the relevant influential factors, and construct a corresponding mathematical model to evaluate prediction efficiency.Methods:In a cross-sectional study, the clinical data of 219 patients with interstitial lung disease associated with connective tissue disease, who were treated at Xi'an International Medical Center Hospital from January 2020 to December 2023, were retrospectively collected and analyzed. Among these patients, 32 were diagnosed with progressive fibrotic interstitial lung disease (observation group), while the remaining 187 patients were diagnosed with non-progressive fibrotic interstitial lung disease (control group). Univariate analysis ( t-test and χ2 test) and multivariate analysis (logistic regression) were conducted to build a predictive model for progressive fibrotic interstitial lung disease. The prediction efficacy was evaluated using a column chart model and receiver operating characteristic curve analysis. Results:In the observation group, the proportions of patients experiencing cough and shortness of breath were 40.63% (13/32) and 40.63% (13/32), respectively, which were significantly higher than those in the control group [16.58% (31/187), 16.04% (30/187), χ2 = 9.84, 10.46, both P < 0.05]. The observation group also exhibited significantly higher levels of white blood cell count, neutrophil-to-lymphocyte ratio, erythrocyte sedimentation rate, and C-reactive protein, while albumin levels were significantly lower compared with the control group ( t = -2.69, -2.15, -9.27, -6.78, 2.18, all P < 0.05). The immunoglobulin A levels in the observation group [(3.18 ± 0.44) g/L] were significantly higher than those in the control group [(2.32 ± 0.32) g/L, t = -13.23, P < 0.05]. Additionally, the levels of carcinoembryonic antigen [(2.73 ± 1.03) μg/L] and carbohydrate antigen 19-9 [(14.35 ± 4.03) kU/L] in the observation group were significantly higher compared with the control group [(1.53 ± 0.24) μg/L, (8.98 ± 2.71) kU/L, t = 13.99, 9.56, both P < 0.05]. The proportion of reticular opacities in the observation group was significantly lower than that in the control group, whereas the proportion of honeycomb changes was significantly higher in the observation group compared with the control group (χ2 = 6.45, 14.55, both P < 0.05). Multivariate logistic analysis revealed that immunoglobulin A, carbohydrate antigen 19-9, and honeycomb changes were independent influential factors associated with the diagnosis of progressive fibrotic interstitial lung disease ( OR = 17.13, 1.42, 8.01, all P < 0.05). The multivariate logistic regression model demonstrated good fit (Hosmer-Lemeshow χ2 = 0.11, P > 0.05). A nomogram risk model was constructed based on the variables identified in the multivariate analysis, with a C-index of 0.71. Internal validation using the Bootstrap sampling method indicated an average absolute error of the calibration curve of 0.02. Receiver operating characteristic curve analysis based on the independent influential factors and their corresponding P-values showed areas under the curve of 0.73, 0.73, 0.68, and 0.86, respectively. The area under the curve for the predicted probability of the regression model was significantly higher than those for the other independent influential factors ( Z = -3.81, -3.66, -4.99, all P < 0.05). Conclusion:Increased immunoglobulin A concentration, elevated carbohydrate antigen 19-9 levels, and honeycomb changes observed on high-resolution CT scans may indicate the progression of pulmonary fibrosis in patients with interstitial lung disease associated with connective tissue disease. Close monitoring of clinical symptoms, comprehensive laboratory and imaging evaluations, and timely antifibrotic treatment are recommended for these patients.

OBJECTIVE: To predict the targets and pathways in the therapeutic mechanism of Guizhi Gancao Decoction (GZGCD) against heart failure (HF) based on network pharmacology. METHODS: The chemical components of GZGCD were analyzed using the databases including TCMSP, TCMID and TCM@Taiwan, and the potential targets of GZGCD were predicted using the SwissTargetPrediction database. The targets of HF were obtained using the databases including DisGeNET, Drugbank and TTD. The intersection targets of GZGCD and HF were identified using VENNY. Uniport database was used to convert the information, and the components-targets-disease network was constructed using Cytoscape software. The Bisogene plug-in, Merge plug-in, and CytoNCA plug-in in Cytoscape software were used for protein-protein interaction (PPI) analysis to acquire the core targets. Metascape database was used for GO and KEGG analysis. The results of network pharmacology analysis were verified with Western blot analysis. Three factors (PKCα, ERK1/2 and BCL2) were screened according to the degree value of network pharmacology results and the degree of correlation with heart failure process. The pentobarbtal sodium was dissolvein H9C2 cells treated with serum-free high glucose medium to simulate the ischemic anoxic environment of heart failure. The total proteins of myocardial cells were extracted. The protein contents of PKCα, ERK1/2 and BCL2 were determined. RESULTS: We identified a total of 190 intersection targets between GZGCD and HF using Venny database, involving mainly the circulatory system process, cellular response to nitrogen compounds, cation homeostasis, and regulation of the MAPK cascade. These potential targets were also involved in 38 pathways, including the regulatory pathways in cancer, calcium signal pathway, cGMP-PKG signal pathway, and cAMP signal pathway. Western blot analysis showed that in an in vitro H9C2 cell model of HF, treatment with GZGCD downregulated PKCα and ERK1/2 expressions and upregulated BCL2 expression. CONCLUSION The therapeutic mechanism of GZGCD for HF involves multiple targets including PRKCA, PRKCB, MAPK1, MAPK3, and MAPK8 and multiple pathways including the regulatory pathway in cancer and the calcium signaling pathway.

Transglutaminase 2 (TGM2) is a ubiquitous multifunctional protein, which is related to the adhesion of different cells and tumor formation. Previous studies found that TGM2 is involved in the interaction between host cells and viruses, but the effect of TGM2 on the proliferation of influenza virus in cells has not been reported. To explore the effect of TGM2 during H1N1 subtype influenza virus infection, a stable MDCK cell line with TGM2 overexpression and a knockout cell line were constructed. The mRNA and protein expression levels of NP and NS1 as well as the virus titer were measured at 48 hours after pot-infection with H1N1 subtype influenza virus. The results showed that overexpression of TGM2 effectively inhibited the expression of NP and NS1 genes of H1N1 subtype influenza virus, while knockout of TGM2 up-regulated the expression of the NP and NS1 genes, and the expression of the NP at protein level was consistent with that at mRNA level. Virus proliferation curve showed that the titer of H1N1 subtype influenza virus decreased significantly upon TGM2 overexpression. On the contrary, the virus titer in TGM2 knockout cells reached the peak at 48 h, which further proved that TGM2 was involved in the inhibition of H1N1 subtype influenza virus proliferation in MDCK cells. By analyzing the expression of genes downstream of influenza virus response signaling pathway, we found that TGM2 may inhibit the proliferation of H1N1 subtype influenza virus by promoting the activation of JAK-STAT molecular pathway and inhibiting RIG-1 signaling pathway. The above findings are of great significance for revealing the mechanism underlying the interactions between host cells and virus and establishing a genetically engineering cell line for high-yield influenza vaccine production of influenza virus.

Methods: A total of 2 752 primary and middle school students aged between 6 and 18 years old were selected in Xiamen. They were divided into malnutrition group, normal group and overweight and obesity group according to the national standards. Statistical analysis was carried out by chi square test, Kruskal wallis test and partial correlation analysis. Results: The prevalence of malnutrition among primary and secondary school students in Xiamen was 8.4%(231), the prevalence of overweight and obesity was 24.2%(667), and the prevalence of overweight and obesity among boys(31.4%) was higher than girls( 17.0 %).The distribution of nutritional status between different ages was statistically significant ( χ 2=40.43, P <0.05). On the lung activity index, both boys and girls were shown to be overweight and obesityConclusion The prevention and control situation of overweight between primary and secondary school students in Xiamen city, is more serious. Overweight and obesity are related to decline in physical function and physical fitness. Nutritional status should be paid more attention for physical fitness improvement among students.

With the increasing incidence rates of metabolic diseases such as obesity and type 2 diabetes, the incidence rate of nonalcoholic fatty liver disease (NAFLD) has also gradually increased year by year. NAFLD has complex underlying pathogeneses which have not yet been fully clarified. As the carrier of intercellular communication, exosomes play an important role in the development and progression of liver diseases. This article summarizes the mechanism of action of exosomes in the pathogenesis of NAFLD and their effect on lipid metabolism, insulin resistance, liver inflammation, and fibrosis, and it is pointed out that exosomes have great potential in the diagnosis and treatment of diseases, which will be the focus of future research.

Objective:To understand the current practice of preoperative bowel preparation in elective colorectal surgery in China.Methods:A cross-sectional questionnaire survey was conducted through wechat. The content of the questionnaire survey included professional title of the participants, the hospital class, dietary preparation and protocol, oral laxatives and specific types, oral antibiotics, gastric intubation, and mechanical enema before elective colorectal surgery. A stratified analysis based on hospital class was conducted to understand their current practice of preoperative bowel preparation in elective colorectal surgery.Result:A total of 600 questionnaires were issued, and 516 (86.00%) questionnaires of participants from different hospitals, engaged in colorectal surgery or general surgeons were recovered, of which 366 were from tertiary hospitals (70.93%) and 150 from secondary hospitals (29.07%). For diet preparation, the proportions of right hemicolic, left hemicolic and rectal surgery were 81.59% (421/516), 84.88% (438/516) and 84.88% (438/516) respectively. The average time of preoperative dietary preparation was 2.03 days. The study showed that 85.85% (443/516) of surgeons chose oral laxatives for bowel preparation in all colorectal surgery, while only 4.26% (22/516) of surgeons did not choose oral laxatives. For mechanical enema, the proportions of right hemicolic, left hemicolic and rectal surgery were 19.19% (99/516), 30.04% (155/516) and 32.75% (169/516) respectively. Preoperative oral antibiotics was used by 34.69% (179/516) of the respondents. 94.38% (487/516) of participants were satisfied with bowel preparation, and 55.43% (286/516) of participants believed that preoperative bowel preparation was well tolerated. In terms of preoperative oral laxatives, there was no statistically significant difference between different levels of hospitals [secondary hospitals vs. tertiary hospitals: 90.00% (135/150) vs. 84.15% (308/366), χ 2=2.995, P=0.084]. Compared with the tertiary hospitals, the surgeons in the secondary hospitals accounted for higher proportions in diet preparation [87.33% (131/150) vs. 76.78% (281/366), χ 2=7.369, P=0.007], gastric intubation [54.00% (81/150) vs. 36.33% (133/366), χ 2=13.672, P<0.001], preoperative oral antibiotics [58.67% (88/150) vs. 24.86% (91/366), χ 2=12.259, P<0.001] and enema [28.67% (43/150) vs. 15.30% (56/366), χ 2=53.661, P<0.001]. Conclusion:Although the preoperative bowel preparation practice in elective colorectal surgery for most of surgeons in China is basically the same as the current international protocol, the proportions of mechanical enema and gastric intubation before surgery are still relatively high.
