Cancer has become a significant global public health issue， severely impacting public health and societal development. Despite advances in tumor treatment methods in recent years and a gradual decline in cancer mortality rates， drug-related adverse reactions and drug resistance remain substantial challenges. Traditional Chinese medicine （TCM） has demonstrated significant clinical efficacy in cancer treatment and small side effects， making it widely applied in the field of oncology. Xuefu Zhuyutang， derived from Yilin Gaicuo， is known for its abilities to invigorate blood circulation， dispel blood stasis， promote Qi flow， and alleviate pain. It was specifically formulated by the esteemed WANG Qingren of the Qing dynasty for the "blood stasis syndrome in the blood mansion" and is commonly used to treat Qi stagnation and blood stasis syndrome. Clinical studies have shown that Xuefu Zhuyutang， when combined with conventional Western medications， produces significant effects in the treatment of malignant tumors such as liver cancer， lung cancer， and cervical cancer. It substantially reduces the incidence of adverse reactions following Western treatments， including radiation esophagitis， radiation encephalopathy， radiation-induced oral mucositis， and edema. Additionally， it alleviates cancer-related pain and fever， blood hypercoagulability， and associated complications such as depression and anxiety， and also mitigates chemotherapy-induced side effects like hand-foot syndrome. Basic research has demonstrated its potential anti-tumor mechanisms， including the inhibition of Wnt/β-catenin signaling pathway activation， suppression of mitogen-activated protein kinase （MAPK） pathway activation， and anti-tumor angiogenesis. Pharmacological studies have revealed that its active components inhibit tumor cell proliferation and migration， induce tumor cell apoptosis， suppress tumor angiogenesis， enhance the cytotoxicity of natural killer cells against tumors， improve the tumor microenvironment， and regulate immune function. This paper reviewed the latest research progress on Xuefu Zhuyutang in the treatment of malignant tumors from four aspects： theoretical exploration， clinical studies， mechanisms of action， and pharmacological basis， aiming to provide insights and methods for the clinical diagnosis and treatment of malignant tumors.

Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.

The authors proposed that the central government agencies and their technical support institutions take a lead to construct a patient-centered dynamic and decentralized national big data sharing platform for rare diseases registry and research, medicines development, production and supply, access to care and medicines, payment and security, utilization surveillance in China. With the support of digital and intelligent technologies, this national platform would be able to link multiple stakeholders to achieve integrated analysis of big data, as well as international sharing and exchange, which will help to effectively and efficiently promote access to medicines for rare diseases in China.

ObjectiveTo screen key genes associated with neuroblastoma （NB） diagnosis and prognosis using the Gene Expression Omnibus （GEO） database， and to investigate the expression and clinical significance of nucleoporin 93 （NUP93） in NB tissues. MethodsNB gene chip data （GSE73517， GSE49710， GSE19274） were retrieved from the GEO database. Differentially expressed genes （DEGs） commonly upregulated in high-risk groups were screened. The R2 database was then used to assess the prognostic value of DEGs that were commonly upregulated in the MYCN amplification group. Finally， NUP93 expression levels in the tissues from 60 NB， 25 ganglioneuroblastoma （GNB）， and 26 ganglioneuroma （GN） cases were measured by immunohistochemistry . ResultsTwenty-five DEGs were identified as commonly upregulated in high-risk groups. Among these， 10 genes （SIVA1， NUP93， STIP1， LSM4， RAI14， MYOZ3， KNTC1， TNFRSF10B， TACC3 and CEP152） showed significantly higher expression in MYCN-amplified subgroups （P＜0.05）. Survival analysis revealed that high NUP93 expression was associated with shorter overall survival （HR = 4.0， 95% CI： 3.0，5.3， P = 1.80 × 10⁻³⁴）. Immunohistochemistry results revealed that NUP93 expression in NB tissues was significantly higher than in GNB and GN tissues （P＜0.001）. NUP93 expression was positively correlated with high mitosis-karyorrhexis index （MKI； P=0.040）， poor differentiation （P＜0.001）， and MYCN expression （r_s = 0.793， P ＜0.001）. ConclusionsHigh expression of NUP93 is associated with high MKI and poor differentiation， and predicts unfavorable prognosis in patients with NB， suggesting it may promote tumor progression by regulating MYCN. NUP93 has the potential to be a novel diagnostic biomarker and therapeutic target for NB.

Tumorigenesis， invasion， and metastasis occur in the context of a persistent inflammatory microenvironment， and a variety of inflammatory factors can lead to the development of various tumors. Guided by the thought of "preventive treatment of disease" in TCM and the concept of tertiary prevention in modern medicine， it is of great significance to effectively intervene in the inflammatory stage of the disease， interrupt disease progression， prevent the occurrence of malignant tumors， and reverse the process of "inflammation-to-cancer transformation". Sinisan， a commonly used prescription in the Treatise on Febrile Diseases， has been widely applied in the treatment of precancerous lesions of the digestive system， demonstrating considerable advantages. This article reviewed literature from the past 20 years， summarizing the application of Sinisan in precancerous lesions of the digestive system from three aspects： the exploration of its prescription-syndrome relationship， clinical application， and mechanistic study. It is found that basic syndrome indications of Sinisan include harmonizing the Earth element to promote spleen-stomach transportation and transformation， soothing the liver and nourishing the Wood element to restore the smooth flow of Qi， and regulating Yin and Yang to relieve stagnation within the system. In clinical application， Sinisan has shown significant efficacy in atrophic gastritis and precancerous conditions such as intestinal metaplasia， gastric ulcer， ulcerative colitis， esophagitis， and pancreatitis. Mechanistic studies have revealed that Sinisan can inhibit inflammatory factors and improve the inflammatory microenvironment， inhibit cell proliferation and regulate apoptosis， exhibit anti-angiogenic and antitumorigenic effects， modulate immune function， and exert antioxidant effects. These mechanisms can be achieved by regulating pathways such as nuclear factor erythroid 2-related factor 2/heme oxygenase-1 （Nrf2/HO-1）， farnesoid X receptor （FXR）/Nrf2， phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt）， Takeda G protein-coupled receptor 5/cyclic adenosine monophosphate/protein kinase A （TGR5/cAMP/PKA）， interleukin-4/signal transducer and activator of transcription 6 （IL-4/STAT6）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， RhoA/Rho-associated protein kinase （RhoA/ROCK）， and transforming growth factor-β/Smad proteins （TGF-β/Smads）， confirming Sinisan's role in reversing the inflammation-to-cancer transformation. The current research status of Sinisan in precancerous lesions of the digestive system was thoroughly examined through the above three aspects， along with the identification of limitations and areas for improvement in current research. The aim is to provide a basis and support for future in-depth research on Sinisan， promote the development of new integrated treatment models combining TCM and Western medicine for precancerous lesions， and aid in the research and development of drugs related to precancerous lesions.

BACKGROUND: Cancer is a major public health concern, particularly among middle-aged and elderly populations, who are disproportionately affected by rising cancer incidence. Environmental pollution has been identified as a significant risk factor for cancer development. China's Carbon Emission Trading Policy (CETP), implemented in pilot regions since 2013, aims to reduce carbon emissions and improve air quality. This study evaluates the impact of CETP on pan-cancer incidence, with a focus on its effects on specific cancer types and vulnerable populations. METHODS: This quasi-natural experiment utilized data from the China Health and Retirement Longitudinal Study (CHARLS) and environmental data from the China National Environmental Monitoring Center (2011-2018). A staggered difference-in-differences (DID) model was employed to estimate the impact of CETP on cancer incidence. Robustness tests, including parallel trend tests, placebo analysis, and entropy balancing, validated the findings. Subgroup analyses were performed to assess the policy's heterogeneous effects based on gender, Body Mass Index (BMI), and smoking status. RESULTS: CETP implementation significantly reduced the incidence of six cancer types: endometrial, cervical, gastric, esophageal, breast, and lung cancers. Overall, pan-cancer incidence significantly declined post-policy implementation (CETP × POST: -47.200, 95% CI: [-61.103, -33.296], p < 0.001). The policy demonstrated stronger effects in highly polluted areas and among individuals with poorer mental health. Subgroup analysis revealed that females, individuals with lower BMI, and non-smokers experienced more substantial benefits. CONCLUSIONS CETP significantly reduces cancer incidence by improving environmental quality and influencing mental health, with particularly strong effects observed among high-risk populations. This study highlights the important role of environmental economic policies in mitigating cancer burden and promoting public health. Future research should further explore the long-term impacts of this policy and its applicability across different national and regional contexts.

Objective:This article reports a case of right sinonasal teratocarcinosarcoma. The patient was admitted to the hospital with symptoms of persistent nasal obstruction in both nostrils. Nasal endoscopy revealed the presence of new growths in the right nasal cavity and nasopharynx. Sinus CT imaging showed that the nasal cavity, paranasal sinuses, and nasopharynx were filled with soft tissue density shadows, with evidence of bone destruction. Transnasal endoscopic sinonasal surgery was performed, and postoperative pathology, along with immunohistochemical results, confirmed a diagnosis of sinonasal teratocarcinosarcoma. This case is analyzed, and relevant literature is reviewed.

Objective:To explore the clinical effectiveness of high-frequency color Doppler ultrasound (HFCDU) assisted harvest of radial artery perforator-pedicled lateral forearm neurocutaneous vascular flap to repair soft tissue defect below the elbow.Methods:A retrospective study was conducted on the clinical data of patients who underwent repair of soft tissue defects below the elbow using the radial artery perforator-pedicled lateral forearm neurocutaneous vascular flap at the Second Hospital of Tangshan from January 2016 to June 2021. Prior to the surgery, HFCDU was utilized to identify and measure the course of the lateral forearm cutaneous nerve and the perforating branch of the radial artery surrounding the wound. Subsequently, the flap rotation point, axis, and area were meticulously designed. During the surgical procedure, the skin flap was harvested either through a subcutaneous tunnel or by direct transfer, while the nerve stump at the defect site was anastomosed end-to-end with the lateral cutaneous nerve of the forearm contained in the skin flap. After reducing the wound at the donor site, it was either directly sutured or repaired using a medium-thick skin graft harvested from the thigh. After surgery, the survival of the skin flap, wound healing at the donor site, and the survival of the skin graft were observed. At the last follow-up, the static two-point discrimination of the flap was measured, and patient satisfaction with the appearance of the flap was assessed using the Michigan hand outcomes questionnaire(MHQ). This questionnaire categorized satisfaction into five levels: very dissatisfied (1 point), dissatisfied (2 points), fair (3 points), satisfied (4 points), and very satisfied (5 points). The scar condition of the donor site was evaluated according to the Vancouver scar scale (VSS), which scored from 0 to 15 points, with higher scores indicating more severe scarring. Descriptive analysis of the data was performed using SPSS 27.0 software.Results:A total of 33 patients were included in the study, comprising 20 males and 13 females, with an average age of (41.0±11.7) years (range, 23-65 years). The defect locations included 6 forearms, 9 wrists, and 18 hands, with all patients having exposed bones and (or) tendons. The defect area ranged from 3.0 cm × 2.5 cm to 12.0 cm × 5.0 cm. The detection result of cutaneous nerves and perforating blood vessels using HFCDU were consistent with the actual findings during surgery, showing no discrepancies. The area of the skin flaps ranged from 3.5 cm × 3.0 cm to 13.0 cm × 6.0 cm. All 33 skin flaps survived postoperatively, with good blood supply and no infections reported; the wounds at the donor site healed primarily, and all grafted skin survived. The duration of postoperative follow-up was (15.6±2.9) months (range, 10-24 months), and the patients’ static two-point discrimination of the flap was measured at (12.5±3.3) mm (range, 8-20 mm). The result of the MHQ indicated that 23 patients were very satisfied with the appearance of the flap (5 points), while 10 patients were satisfied (4 points). The VSS score for the donor site was (4.3±0.9) points (range, 3-6 points), indicating that the scar at the donor site was mild.Conclusion:HFCDU can accurately identify the lateral forearm cutaneous nerve and the perforating branch of the radial artery.The radial artery perforator-pedicled lateral forearm neurocutaneous vascular flap can provide a reliable blood supply, good appearance, sense and patient satisfaction, which is suitable for repairing soft tissue defects below the elbow.
