Hepatocellular carcinoma （HCC） is a common primary malignant tumor. In recent years， the role of ubiquitin-specific proteases （USPs） in HCC has attracted widespread attention. USPs are a class of key deubiquitinating enzymes that affect a variety of biological processes by regulating the ubiquitination status of proteins. Studies have shown that USPs participate in the regulation of cell proliferation， apoptosis， migration， and invasion by deubiquitinating various tumor-related proteins. In addition， the abnormal expression of USPs is closely associated with the prognosis of HCC patients and may thus be used as potential biomarkers and therapeutic targets. This article reviews the research advances in USPs in HCC and explores their key roles in the development， progression， and metastasis of HCC. A deep understanding of the mechanism of action of USPs in HCC not only helps to reveal the pathogenesis of HCC， but also provides a scientific basis for developing new diagnostic tools and treatment strategies. Future research should further explore the regulatory effect of USPs in HCC， in order to provide more effective means for the clinical treatment of HCC.

The etiology of tumors is complex and influenced by multiple factors, including the host and environmental conditions. Allergy is primarily driven by the immune response of helper T cell 2 (Th2). Research has shown that the Th2 immune response is closely related to tumors, which is specifically manifested through Th2 antibodies, allergy-related effector cells and mediators within the tumors, as well as tumor immune-related functions. This internal interaction mechanism will increase the complexity and challenges associated with the clinical diagnosis and treatment of tumors and allergy. The formation of allergic constitution is shaped by both congenital and acquired factors, and its physical state is closely linked to the occurrence and progression of allergic diseases. Therefore, this paper aims to explore the relationship between tumors and allergic reactions from the perspective of traditional Chinese medicine (TCM) constitution theory. Based on the four basic principles of the TCM constitution, including endowment inheritance theory, environment constraint theory, body-spirit composition theory, and life process theory, this exploration will focus on four aspects: genetic factors and internal disease causes, inflammatory environments and functional regulation, psychological disorders and emotional pathogenesis, as well as age structure and disease risk. Furthermore, from the perspective of constitution-disease relation of chronic disease prevention, this paper will discuss the significant importance of adjusting allergic constitution to improve both subjective symptoms and objective indicators of allergic reactions in tumor patients.

As a complex autoimmune disease， rheumatoid arthritis （RA） involves immune microenvironment dysregulation resulting from excessive activation of pyroptosis， which is a crucial factor in disease progression. Based on the theory of ying-wei in traditional Chinese medicine， "ying decline and wei attack" is considered the fundamental pathogenesis of RA. Pyroptosis serves as a microscopic manifestation of this concept， suggesting a potential correlation between "ying decline and wei attack" and pyroptosis nd immune microenvironment dysregulation in RA. Accordingly， treatment principles based on this theory are proposed： in the early stage of the disease， boosting wei to consolidate the exterior， and regulating ying to dispel pathogens； in the middle and late stages， harmonizing ying to remove stagnation， and nourishing its transformational source.

Liver cancer has high prevalence and mortality rates around the world， and its development and progression are closely associated with the interaction between the tumor microenvironment and tumor-associated macrophages （TAMs）. TAMs play a significant role in immune suppression， immune escape， cell proliferation， invasion， metastasis， and drug resistance in liver cancer. Traditional Chinese medicine （TCM）， with its unique therapeutic concepts and methods， has shown great potential in regulating TAMs and improving the prognosis of liver cancer. This article reviews the role and molecular mechanisms of TCM in regulating TAMs for the treatment of liver cancer， discusses the key role of TAMs in the progression of liver cancer， and analyzes the impact of Chinese medicinal components on the recruitment， polarization， and activity of TAMs and the expression of related factors based on TCM theory. Studies have shown that TCM can regulate the polarization state of TAMs， promote the formation of M1-type antitumor macrophages， and inhibit the activity of M2-type tumor macrophages， thereby playing a role in inhibiting the proliferation of liver cancer cells， promoting apoptosis， inhibiting angiogenesis， and enhancing immune response. In addition， this article also summarizes the molecular targets and mechanisms of action of TCM monomers， compound prescriptions， and novel preparations in the treatment of liver cancer， such as inhibiting the secretion of cytokines by TAMs， regulating signaling pathways， and affecting metabolic pathways， in order to provide a scientific basis for the application of TCM in liver cancer treatment and offer new ideas for immunotherapy for liver cancer.

Objective:To investigate the CT image characteristics of anterior ethmoidal artery（AEA） through CT scan and its significance in nasal endoscopic surgery. Methods:A retrospective study of 82 patients（164 sides） with chronic sinusitis was conducted. All patients underwent CT scan and the images were reconstructed. The AEA classification was used and calculate the rate of AEA suspension. The AEA was classified, and the suspension rate of the AEA was calculated. The height of the lateral lamella of the cribriform plate （LLCP） was measured, and Keros classification was performed. The relationship between Keros classification and AEA suspension was analyzed. The supraorbital ethmoidal cell （SOEC） was identified, and its relationship with AEA suspension was analyzed. Results:Type Ⅰ AEA accounted for 42.07%（69/164）. Type Ⅱ AEA accounted for 22.56%（37/164）. Type Ⅲ AEA accounted for 35.37%（58/164）. The suspension rate was 35.37%. The average height of the LLCP was （3.7±1.8） mm. In the Keros classification, type Ⅰaccounted for 53.05%（87/164）, Type Ⅱaccounted for 37.80%（62/164）. Type Ⅲ accounted for 9.15%（15/164）. The results of the Spearman analysis showed that there was a moderate positive correlation between the Keros classification and the suspension of the AEA（r=0.526, P<0.01）. Among 164 sides, SOEC was present in 15 sides. The suspension rate of AEA in the group with SOEC was significantly higher than that in the group without SOEC（P<0.01）. Conclusion:Sinus CT and multiplanar reconstruction can clarify the image characteristics of AEA and its relationship with surrounding structures. When the level of Keros classification is higher or SOEC is present, the suspension rate of AEA increases significantly. It is of great significance to clarify the characteristics of AEA before surgery in order to avoid injury during surgery.

Cerebral edema is characterized by fluid accumulation, and the glymphatic system (GS) plays a pivotal role in regulating fluid transport. Using the Tenecteplase system, magnesium salt of salvianolic acid B/ginsenoside Rg1 (SalB/Rg1) was injected intravenously into mice 4.5 h after middle cerebral artery occlusion and once every 24 h for the following 72 h. GS function was assessed by Evans blue imaging, near-infrared fluorescence region II (NIR-II) imaging, and magnetic resonance imaging (MRI). SalB/Rg1 had significant effects on reducing the infarct volume and hemorrhagic transformation score, improving neurobehavioral function, and protecting tissue structure, especially inhibiting cerebral edema. Meanwhile, the influx/efflux drainage of GS was enhanced by SalB/Rg1 according to NIR-II imaging and MRI. SalB/Rg1 inhibited matrix metalloproteinase-9 (MMP-9) activity, reduced cleaved β-dystroglycan (β-DG), and stabilized aquaporin-4 (AQP4) polarity, which was verified by colocalization with CD31. Our findings indicated that SalB/Rg1 treatment enhances GS function and attenuates cerebral edema, accompanying the regulation of the MMP9/β-DG/AQP4 pathway.

Objective:To investigate the iodine nutritional status, prevalence and distribution characteristics of thyroid nodules among children and adolescents in Jurong City, Jiangsu Province, and study the risk factors for thyroid nodules in children and adolescents.Methods:In 2021, a cluster sampling method was used to select one primary and one secondary school in the urban and rural areas of Jurong City, ≥150 children and adolescents were selected as survey respondents from each school on a class-by-class basis, including third-grade children in primary schools and seventh-grade adolescents in secondary schools. The basic information and mental health status of survey respondents were collected by basic information questionnaires and Children's Anxiety Related Emotional Disorders Screening Form (SCARED). Water samples were collected from schools where survey respondents were enrolled and from townships where schools were located, and the iodine content in the water were tested. At the same time, household salt and urine samples from survey respondents were collected to test the salt iodine and urine iodine. Thyroid volume and thyroid nodules were measured using B-ultrasound method to analyze goiter (swelling of the thyroid gland) and thyroid nodules. The Cochran-Armitage trend test method was applied for trend analysis, and a multivariate logistic regression model was used to analyze the risk factors for thyroid nodules.Results:A total of 710 children and adolescents (370 males and 340 females) were surveyed, including 347 children (169 males and 178 females) and 363 adolescents (201 males and 162 females). A total of 14 water samples were collected, with an iodine content range of 8.98 to 10.82 μg/L and a median iodine content of 9.98 μg/L. A total of 710 edible salt samples were tested, with a salt iodine content of (20.94 ± 1.94) mg/kg, an iodine salt coverage rate of 100.00%, and a qualified iodine salt consumption rate of 97.46% (692/710). A total of 710 urine samples were tested, with a median urine iodine of 288.13 μg/L, median urinary iodine for boys and girls was 310.29 and 245.12 μg/L, respectively, and the difference between the two was statistically significant ( Z = - 5.91, P < 0.001). A total of 710 children and adolescents were tested by B-ultrasound, and the detection rate of goiter and thyroid nodules was 2.25% (16/710) and 25.07% (178/710). There was no significant upward trend in the detection rate of thyroid nodules with age (χ 2trend = 0.45, P = 0.651). The detection rates of thyroid nodules in boys and girls were 20.00% (74/370) and 30.59% (104/340), respectively, and the difference between the two was statistically significant (χ 2 = 10.57, P < 0.001). Multivariate logistic regression analysis indicated that female students who participated in extracurricular tutoring/interest classes in the past month were two influencing factors for thyroid nodules in children and adolescents ( OR = 1.76, 1.54, 95% CI: 1.25 - 2.49, 1.09 - 2.17, P < 0.05). Conclusions:The iodized salt coverage rate, qualified iodized salt consumption rate, and goiter rate in children and adolescents in Jurong City have all reached the elimination standard for iodine deficiency disorders, and their iodine nutrition is at a super-appropriate level. However, the external environment of Jurong City is still iodine-deficient. The detection rate of thyroid nodules in children and adolescents is at a high level. Female students and those who have participated in extracurricular tutoring/interest classes in the past month are risk factors for thyroid nodules in children and adolescents.
