Diabetic nephropathy （DN） is one of the most common and serious microvascular complications of diabetes mellitus and represents a major cause of chronic kidney disease progression and end-stage kidney disease， thereby constituting a major public health problem that adversely affects the prognosis and quality of life of patients with diabetes mellitus. The pathogenesis and progression of DN are complex and involve multiple pathological processes， including insulin resistance， inflammation， oxidative stress， lipid deposition， podocyte injury， and renal fibrosis. Although current clinical therapies can delay the progression of DN to some extent， their effectiveness remains limited by marked interindividual variability in therapeutic response and the difficulty of fully reversing renal injury. Therefore， further elucidation of the key molecular mechanisms underlying DN and the exploration of effective therapeutic strategies are of considerable importance. In recent years， with advances in the understanding of DN pathogenesis， peroxisome proliferator-activated receptor γ （PPARγ）， an important nuclear receptor transcription factor involved in the regulation of insulin resistance， inflammation， oxidative stress， and fibrotic processes， has attracted increasing attention for its role in the development and progression of DN. Traditional Chinese medicine （TCM）， characterized by multi-component， multi-target， and multi-pathway synergistic regulation， may ameliorate pathological processes including metabolic abnormalities， inflammation， oxidative stress， lipid deposition， and renal fibrosis in DN by targeting PPARγ and its associated signaling networks. This review systematically summarizes the mechanisms by which PPARγ and its related signaling pathways regulate DN and reviews recent advances in TCM interventions targeting the PPARγ signaling pathway in DN. Such TCM interventions encompass single herbs such as Coptidis Rhizoma， active constituents such as quercetin， astragaloside Ⅳ， and trigonelline， extracts of herbs such as Plantaginis Herba and Dendrobii Nobilis Caulis， and formulas such as Huangkui capsules， Shenshuaining granules， and Mudan granules. This review aims to provide a theoretical basis for the prevention and treatment of DN with TCM.

Precancerous lesions of gastric cancer （PLGC） are a group of pathological changes caused by abnormalities in the structure， morphology， and differentiation of gastric mucosal epithelial cells. Since the early symptoms are hidden and non-specific， PLGC is not easy to be diagnosed and it has often developed into intermediate or advanced gastric cancer once being diagnosed and missed the best time for treatment. Accordingly， the incidence of this disease is increasing year by year， which lifts a heavy burden on the patients. The pathogenesis of PLGC is complex， involving inflammatory microenvironment， bile reflux， glycolysis， autophagy， and apoptosis. Currently， PLGC is mainly treated with anti-inflammatory and endoscopic therapies， which are difficult to curb the development of PLGC. Therefore， seeking a safe and effective therapy is an important topic of modern research. Traditional Chinese medicine （TCM）， characterized by treatment based on syndrome differentiation and a holistic view， exerts effects via multiple pathways， mechanisms， and targets. Recent studies have confirmed that TCM can regulate the phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin （PI3K/Akt/mTOR）， Wnt/β-catenin， Sonic Hedgehog， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， hypoxia-inducible factor-1α （HIF-1α）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2） and other signaling pathways. By targeting these pathways， TCM can inhibit aerobic glycolysis， reduce oxidative stress， repair the inflammatory microenvironment， regulate cellular autophagy， and promote vascular normalization， thereby delaying or reversing PLGC. However， few researchers have systematically summarized the TCM regulation of PLGC-associated pathways. By reviewing the relevant articles at home and abroad， this paper summarized the roles of the above signaling pathways in the development of PLGC and the research progress in the regulation of signaling pathways by TCM in the treatment of PLGC， with a view to providing a new theoretical basis for the clinical research on PLGC and the drug development for this disease.

Objective To explore the coupling mechanism between medical surge response resources and the spread of secondary risks during public health emergencies,as well as the effectiveness of relevant interventions.Methods Based on complex network theory,a dual-layer network model of medical resources and secondary events was constructed.The interactive feedback between medical resource status and secondary event risk,as well as the effects of network structure,were analyzed through MATLAB simulations,REPAST agent-based modeling,and mean-field analysis.Results Simulation and prediction results show that an increase in first-layer resource-deficient nodes significantly raises the activation rate and transmission speed of secondary events,while the clustering and spread of secondary events in the second layer,in turn,intensify resource depletion,creating a negative feedback loop.Mean-field analysis indicates a nonlinear positive correlation between the adequacy of medical resources and the likelihood of secondary events.Network structure analysis reveals that when the average node degree exceeds 8,resource allocation efficiency improves markedly.Conclusion There exists a dynamic coupling and bidirectional feedback relationship between medical resource status and secondary event risks.Enhancing the flexible allocation and responsiveness of medical resources,improving multi-sectoral collaborative monitoring and coordinated regulation,optimizing network connectivity and coordination mechanisms for resource distribution,and establishing dynamic monitoring and tiered early warning systems are key strategies for strengthening the resilience of healthcare systems and effectively containing the spread of secondary events.

Tic disorder is a chronic neuropsychiatric disorder with complex etiology and diverse phenotypes,and its incidence has been increasing significantly in recent years.Most scholars believe that abnormalities in the cortico-striatal-thalamo-cortical circuit and its interconnected brain regions are closely related to the development of tic disorder.Chinese materia medica intervention in tic disorders is characterized by multi-targets,multi-mechanisms and holistic nature,and has a good prospect for research application.This article summarized the experimental studies of TCM compound intervention in tic disorder in recent years,which have shown that TCM compounds could reduce the damage of nerve cells through the regulation of neurotransmitters,inflammatory response,immune function and the"colony-gut-brain axis"to improve and prevent tic disorder,which could provide a reference for the research and development of new medicines for tic disorder and for the clinical research.

The technology of three-dimensional(3D)printing emerged in the late 1970s and has since undergone considerable development to find numerous applications in mechanical engineering,industrial design,and biomedicine.In biomedical science,several studies have initially found that 3D printing technology can play an important role in the treatment of diseases in hepatopancreatobiliary surgery.For example,3D printing technology has been applied to create detailed anatomical models of disease organs for preoperative personalized surgical strategies,surgical simulation,intraoperative navigation,medical training,and patient education.Moreover,cancer models have been created using 3D printing technology for the research and selection of chemotherapy drugs.With the aim to clarify the development and application of 3D printing technology in hepatopancreatobiliary surgery,we introduce seven common types of 3D printing technology and review the status of research and application of 3D printing technology in the field of hepatopancreatobiliary surgery.

Lung cancer is one of the most common malignant tumors in the world， with its morbidity and mortality ranking at the top. The early symptoms are not obvious， and the biological structure is complex， so many patients have missed the optimal treatment time. At present， the treatment of lung cancer in modern medicine is dominated by first-line chemotherapy and surgical treatment with platinum-containing regimen， which has relatively large side effects， poor prognosis， and a high risk of metastasis and recurrence. With the gradual rise of targeted therapy and immunotherapy for lung cancer， the overall recovery of patients with lung cancer is still poor and the survival rate is low， despite more abundant treatment methods. From the perspective of holistic concept and syndrome differentiation， traditional Chinese medicine （TCM） plays an important role in the prognosis of tumor patients， with many targets， a wide range and light toxic and side effect. Modern studies have shown that the occurrence and development of lung cancer are closely related to the abnormality of multiple signaling pathways， and the Wnt/β-catenin signaling pathway， as one of the most important pathways in cancer， is involved in the whole process of lung cancer development by regulating the expression of related signaling proteins and genes. In recent years， many studies have confirmed that TCM monomers and TCM compounds can inhibit the epithelial-mesenchymal transition （EMT） process of lung cancer and the activity of lung cancer stem cells （LCSCs） by regulating the Wnt/β-catenin signaling pathway， induce lung cancer cell apoptosis， inhibit the proliferation， invasion and migration of lung cancer cells， and thus play an anti-lung cancer role. In recent years， research in this field has made breakthroughs， but there is a lack of systematic reviews and summaries. Thus， this paper reviewed relevant literature worldwide to analyze and interpret the mechanism of TCM intervention in the Wnt/β-catenin signaling pathway against lung cancer. The TCM monomers targeted to regulate this signaling pathway were summarized in four categories： promoting blood circulation for removing blood stasis， clearing heat and removing dampness， clearing heat and removing toxicity， and awakening the spirit. TCM compounds included Buzhong Yiqitang， Xuefu Zhuyutang， et al. This study aims to provide new ideas for clinical research and drug development for lung cancer.

Based on the theory of "one qi circulation" founded by HUANG Yuanyu， the core disease mechanism of colorectal cancer is the innate spleen deficiency and stomach qi failing to bear downward， which leads to the turbidity assemble in large intestine， forming the carcinoma toxin， and ultimately transforms into colorectal cancer. The treatment should base on recovering the circulation of qi， Huangya Decoction （黄芽汤） as the basic formula， the circulation of qi ascending and descending as the base， adjusting ascending and descending together with Xiaqi Decoction （下气汤）， and differentiating the syndrome on yin-yang excess-deficiency； for spleen-kidney yang deficiency syndrome， treated with Tianhun Decoction （天魂汤） to supplement liver， kidney and assist yang； for liver-kidney yin deficiency syndrome， treated wtih Dipo Decoction （地魄汤） to supplement lung， kidney， and assist yang. They jointly prompt one qi circulation to provide the thoughts for the treatment of colorectal cancer by traditional Chinese medicine.
