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.

With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.

[Objective] To establish a cryopreservation protocol for small-volume (≤1 mL) red blood cells (RBCs) and to evaluate the reactivity and stability of blood group antigens after cryopreservation, so as to explore its potential application in immunohematology reference laboratories. [Methods] Small-volume RBCs were cryopreserved for 120 days, followed by thawing and deglycerolization to restore the RBC components. The quality of the RBCs was assessed. Serum antibodies were serially diluted and reacted with RBCs before and after cryopreservation, and agglutination scores were recorded to quantitatively evaluate the reactivity and stability of blood group antigens such as Rh, Duffy, Lewis, Kidd, M, and H. Flow cytometry was used to analyze the percentage and mean fluorescence intensity of ABO antigen expression on RBCs before and after cryopreservation to assess the usability of cryopreserved RBCs in flow immunophenotyping and blood group subtype studies. [Results] The hemolysis rate of thawed and deglycerolized RBCs was (0.27±0.10)%, with a supernatant free hemoglobin level of (0.52±0.14) g/L, and the RBC recovery rate was (69.12±7.91)%. The direct antiglobulin test (DAT) was negative for all thawed RBCs. There was no difference in the reactivity of blood group antigens before and after cryopreservation, and no difference in the percentage and mean fluorescence intensity of A and B antigen expression on RBCs before and after cryopreservation. [Conclusion] The small-volume RBC cryopreservation protocol can be applied to immunohematology analysis in reference laboratories and is expected to be widely used in blood group identification, antibody screening, identification, and blood group-related research.

Objective To assess the effect of early nutritional intervention on the patients with respiratory diseases at nutritional risk. Methods A total of 130 patients with respiratory disease who were hospitalized in Shanghai Fifth People’s Hospital, Fudan University between May 2023 and December 2024 and had a nutritional risk screening 2002 score ≥3 points. Based on the initiation time of nutritional intervention, patients were divided into an early group (≤5 days, n＝65) and a late group (＞5 days, n＝65). Results In the early group, prealbumin (P-ALB) and retinol-binding protein (RBP) levels were significantly higher (P＜0.01), C-reactive protein (CRP), procalcitonin (PCT) levels were significantly lower after intervention (P＜0.05). Compared with the late group, the hospital costs were lower and hospital stays were shorter in the early group (P＜0.001). Spearman analysis showed ALB, P-ALB, and total protein (TP) were negatively correlated with hospital costs (r＝－0.37, －0.20, and－0.22, P＜0.05). RBP, ALB, P-ALB, and lymphocyte count (LYM) were negatively correlated with CRP (r＝－0.30, －0.26, －0.37, －0.18, P＜0.01), RBP, ALB, P-ALB, hemoglobin (HB), and TP were negatively correlated with PCT (r＝－0.23,－0.36, －0.40, －0.30, －0.19, P＜0.05). Conclusions For patients with respiratory diseases, early nutritional assessment should be underwent, and for patients with nutritional risk screening 2002 score ≥3 points, early nutritional intervention could improve the nutritional status and alleviate inflammatory response, promote recovery, shorten the hospital stays.

BackgroundCurrently， the problem of depressed mood in college students is becoming more prominent. The experience of childhood maltreatment is a significant contributor to depression among college students. Although the association between the two has been confirmed， the specific psychosocial mechanisms underlying how childhood maltreatment affects college students' mental health remain insufficiently evidenced. ObjectiveTo explore the mediating role of emotion regulation difficulties in the relationship between childhood maltreatment and depression among college students， and to investigate the moderated effects of psychological resilience and family socioeconomic status， aiming to provide references for improving depressive symptoms in college students. MethodsOn 14 March 2024， a cluster sampling method was employed to recruit 751 college students from a university in Heilongjiang Province. Participants were assessed with Childhood Trauma Questionnaire （CTQ）， Difficulties in Emotion Regulation Scale （DERS）， Patients' Health Questionnaire Depression Scale-9 item （PHQ-9）， 10-item Connor-Davidson Resilience Scale （CD-RISC-10） and Family Socioeconomic Status Questionnaire. Pearson correlation analysis was adopted to examine the correlation between the scores of scales. Model 4 and model 7 in Process 4.2 were used to test the mediating effects of emotional regulation difficulties and the moderated effects of psychological resilience and family socioeconomic status. Results① A total of 712 （94.81%） valid questionnaires were collected. ② College students' CTQ score was positively correlated with DERS score and PHQ-9 score （r=0.296， 0.507， P<0.01）， and negatively correlated with CD-RISC-10 score and Family Socioeconomic Status Questionnaire score （r=-0.148， -0.229， P<0.01）. ③ The indirect effect value of difficulties in emotion regulation on the relationship between childhood maltreatment and depression was 0.091 （95% CI： 0.018~0.046）， accounting for 17.95% of the total effect. ④ The first half of the mediation model "childhood maltreatment → difficulties in emotion regulation → depression" （childhood maltreatment → difficulties in emotion regulation） was moderated by psychological resilience （β=-0.030， t=-6.147， 95% CI： -0.040~-0.020） and family socioeconomic status （β=-0.051， t=-3.929， 95% CI： -0.077~-0.026）. ConclusionChildhood maltreatment exerts both a direct effect on college students' depression and an indirect effect through emotion regulation difficulties. The childhood maltreatment → emotion regulation difficulties pathway in this mediation model is moderated by psychological resilience and family socioeconomic status. ［Funded by Qiqihar Medical University Graduate Student Innovation Fund Project （number， QYYCX2023-48）； Special Research Fund Project for Young Doctors of Qiqihar Academy of Medical Sciences （number， QMSI2021B-08）］

Diffuse large B-cell lymphoma （DLBCL） is a highly heterogeneous disease. Although standard first-line regimens can cure ＞50% of patients， approximately one-third of them develop relapsed/refractory DLBCL （r/r DLBCL）. Consequently， immunotherapy targeting molecular abnormalities has become pivotal for managing r/r DLBCL. The results of this review show that with advances in understanding DLBCL pathogenesis and the tumor immune microenvironment， antibody-based therapies have evolved rapidly， progressing from monoclonal antibodies （e.g.， rituximab， tafasitamab） to bispecific antibodies（e.g.， odronextamab，glofitamab， epcoritamab） and antibody-drug conjugate （e.g.， polatuzumab vedotin， loncastuximab tesirine）. These engineered agents enhance immune cytotoxicity and tumor-specific targeting， providing novel therapeutic options for r/r DLBCL patients.

ObjectiveTo investigate the correlation of the serum levels of aminotransferases and their ratios with liver inflammation activity in pediatric chronic hepatitis B （pCHB） patients， and to provide a basis for selecting the dominant population for treatment. MethodsThis study was conducted among 1 267 pCHB patients who were admitted to The Fifth Medical Center of Chinese PLA General Hospital from January 2010 to August 2022 and these patients did not receive antiviral therapy. The patients were analyzed in terms of demographic features， blood routine， blood biochemistry， HBV serological markers， and liver biopsy data. According to liver inflammation activity based on liver biopsy， the patients were divided into no or mild inflammation activity （G0‍ ‍—‍ ‍G1） group and significant inflammation activity （G2‍ ‍—‍ ‍G4） group. The serum levels of aminotransferases and their ratios were compared between groups， and their correlation with liver inflammation activity in pCHB patients was analyzed. Additionally， the patients were stratified by the age， and the relationship between serum aminotransferase levels and liver inflammation activity was analyzed in each age group. For comparison of continuous data between two groups， the independent samples t-test was used when the data were normally distributed， while the Mann-Whitney U test was used when the data were not normally distributed； the chi-square test was employed for comparison of categorical data between two groups. A Spearman’s correlation analysis was performed for correlation assessment. ResultsAmong the 1 267 pCHB patients， there were 468 （36.9%） in the G0‍ ‍—‍ ‍G1 group and 799 （63.1%） in the G2‍ ‍—‍ ‍G4 group， and there were significant differences between the two groups in the levels of aspartate aminotransferase （AST）， alanine aminotransferase （ALT）， AST/ALT ratio， gamma-glutamyl transpeptidase （GGT）， total bilirubin， direct bilirubin， HBeAg quantification， low-density lipoprotein， and platelet count （PLT） （all P<0.05）. The correlation analysis showed that liver inflammation activity was negatively correlated with PLT and low-density lipoprotein （both P<0.05） and was positively correlated with GGT， total bilirubin， direct bilirubin， and HBeAg titer （all P<0.05）， while it was not significantly correlated with ALT， AST， and AST/ALT ratio （all P>0.05）. In the 0‍ ‍—‍ ‍12 years group， the 13‍ ‍—‍ ‍18 years male group， and the 13‍ ‍—‍ ‍18 years female group， liver inflammation activity aggravated with the increases in the serum levels of ALT and AST， and there were significant differences between groups （all P<0.05）. In the 0‍ ‍—‍ ‍12 years group， there was a significant difference in significant liver inflammation activity between the AST/ALT ratio >1 group and the AST/ALT ratio ≤1 group （P<0.001）. Among the 1 267 patients， 447 （35.28%） had an ALT level of <2×upper limit of normal （ULN）， among whom 196 （43.85%） had G≥2 liver inflammation， accounting for 15.47% of all children enrolled. ConclusionLiver inflammation activity is not significantly correlated with ALT， AST， and AST/ALT ratio in pCHB patients， suggesting that the serum levels of aminotransferases cannot truly reflect liver inflammation activity in pCHB patients with an aminotransferase level of <2×ULN. In clinical practice， liver biopsy should be performed for children with an aminotransferase level of <2×ULN to clarify whether antiviral therapy should be performed.

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.

Malignant tumor is a serious and difficult disease threatening human health， which has a high morbidity and mortality rate worldwide. Traditional Chinese medicine has unique advantages in improving the therapeutic effect of malignant tumors and alleviating adverse reactions. Traditional Chinese medicine believes that Qi deficiency and blood stasis are important pathogeneses in the development of malignant tumors， and the method of supplementing Qi and activating blood is an effective strategy for treating malignant tumors. Astragali Radix， sweet in taste and warm in nature， has effects of tonifying Qi and rising Yang， strengthening the exterior and reducing sweat， promoting fluid and nourishing blood. Curcumae Rhizoma， acrid and bitter in taste and warm in nature， has the effects of promoting Qi and breaking blood stasis， eliminating mass， and relieving pain. Astragali Radix-Curcumae Rhizoma， as the classic herb pair of invigorating Qi and activating blood， has a clear effect on inhibiting tumor growth and metastasis. Studies have shown that Astragali Radix-Curcumae Rhizoma contains astragalus polysaccharide， astragaloside， calycosin， formononetin， curcumin， β-elemene， curcumenol， curcumenone， curcumendione， gemacrone， and other anti-tumor active ingredients. It can significantly inhibit the occurrence and development of liver cancer， colorectal cancer， gastric cancer， lung cancer， ovarian cancer， cervical cancer， breast cancer， and other cancers and has the advantages of superposition effect， synergistic complementarity， and increased dissolution compared with single herb and monomer of Chinese traditional herbs and has been widely valued in the field of TCM anti-cancer. Its anti-tumor mechanism includes inhibition of tumor cell proliferation， promotion of tumor cell apoptosis and autophagy， anti-invasion and metastasis， regulation of immune function， and enhancement of anti-tumor drug sensitivity. By combining Chinese and foreign literature， the compatibility effect and anti-tumor mechanism of Astragali Radix-Curcumae Rhizoma were summarized， and then scientific compatibility of these two herbs was expounded， in order to provide a useful reference for clinical application and future research of Astragali Radix-Curcumae Rhizoma.
