Gastrointestinal tumors （GTs）， including colorectal cancer， gastric cancer， liver cancer， pancreatic cancer， and esophageal cancer， are increasing in incidence worldwide and have become one of the major diseases threatening human health. Tumor stem cells （TSCs）， an undifferentiated subpopulation within tumor tissues， possess biological characteristics such as self-renewal， multidirectional differentiation， high tumorigenicity， and resistance to radiochemotherapy. They play an important role in the occurrence， progression， recurrence， and metastasis of GTs and have increasingly become a research hotspot in GT treatment. Although modern medicine has made remarkable progress， there remain many problems in therapeutic approaches targeting TSCs. In this context， traditional Chinese medicine （TCM）， with its favorable safety profile and multi-target mechanisms， has shown potential advantages and value in regulating TSCs. It can reduce TSC drug resistance， enhance the sensitivity of tumor cells to chemotherapeutic agents， inhibit tumor growth and metastasis， and has shown unique advantages in improving the quality of life and prolonging the survival of GT patients. Studies have found that active components of Chinese medicine， such as terpenoids， polyphenols， flavonoids， glycosides， and quinones， and Chinese medicine compound formulas， including Zuojin pills， Sijunzi decoction， Biejiajian pills， and Xuanfu Daizhe decoction， can inhibit TSCs-related signaling pathways such as the Notch signaling pathway， the Wnt/β-catenin signaling pathway， the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway， and the Hippo signaling pathway. They also reduce the expression of TSC surface markers， including sex-determining region Y-box 2 （SOX2）， sex-determining region Y-box 9 （SOX9）， octamer-binding transcription factor 4 （OCT4）， prominin-1 （CD133）， cluster of differentiation 44 （CD44）， cluster of differentiation 24 （CD24）， and thyroid transmembrane protein 1 （CD90）， thereby hindering TSC differentiation， accelerating their metabolic processes， improving the tumor microenvironment， and consequently inhibiting GT growth. This study collects and analyzes recent research on the regulation of TSCs by TCM in the treatment of GT， aiming to provide a new theoretical basis for tumor therapy with TCM， expand its application in the comprehensive treatment of GT， and offer new therapeutic ideas and methods for clinical practice.

Immune checkpoint inhibitors(ICIs)represent the most widely used immunotherapeutic approach for antitumor treatment,yet the understanding of their associated hepatotoxicity remains incomplete.This article delves into and analyzes the similarities and differences among the management guidelines on ICI-related hepatotoxicity issued by the Chinese Society of Clinical Oncology(CSCO),the National Comprehensive Cancer Network(NCCN)of the United States,and the American Society of Clinical Oncology(ASCO),aiming to provide a more comprehensive management strategy for clinical practice.By reviewing and analyzing the latest guidelines,this study compares the differences and similarities in the diagnosis,assessment,grading criteria,and treatment strategies for ICI-related liver toxicity among these guidelines.The definitions and diagnostic criteria for ICI-related liver toxicity are generally consistent across different guidelines,primarily relying on the elevated levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),bilirubin,and alkaline phosphatase(ALP)for grading.Notably,the ASCO guidelines place a stronger emphasis on the assessment of symptoms of hepatic dysfunction.In terms of treatment strategies,all guidelines recommend using corticosteroids or immunosuppressants based on the toxicity grade.However,there are discrepancies in management strategies among the guidelines.Clinicians should tailor management strategies by considering the specific conditions of patients and integrating the recommendations from various guidelines.Additionally,given the current inadequate understanding of ICI-induced hepatotoxicity primarily manifested as cirrhosis in the existing guidelines,it is imperative to continuously update and refine these management guidelines as research progresses and clinical experience accumulates.

Objective:To establish age- and gender-based normative values of sagittal spinal-pelvic alignment in Chinese adult population, and to investigate influence of age, gender and ethnicity on sagittal spinal-pelvic alignment in Chinese normal adults.Methods:A total of 786 asymptomatic Chinese adult volunteers aged between 20 and 89 years were prospectively recruited from different spine centers. The inclusion criteria were: 1) age between 20 to 89 years old; and 2) Oswestry disability index (ODI) scored lower than 20. The exclusion criteria were: 1) previous history of spinal, pelvic or lower limb pathologies that could affect the spine; 2) presence of recent and/or regular back pain; 3) previous surgeries on spine, pelvic and/or lower limb; and 4) pregnancy. Demographic characteristics of these subjects including age, gender, body weight and height were recorded. During the enrollment of volunteers, 16 groups were defined based on the age (20 s, 30 s, 40 s, 50 s, 60 s, 70 s and 80 s) and gender. Whole body biplanar standing EOS X-ray radiographs were acquired to evaluate the sagittal alignment. Spinal-pelvic parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), thoracic kyphosis (T 5-T 12, TK), lumbar lordosis (L 1-S 1, LL), lower lumbar lordosis (L 4-S 1, LLL), global tilt (GT), T1 pelvic angle (TPA) and sagittal vertical axis (SVA) were measured. Values of PI-LL and lordosis distribution index (LLL/LL, LDI) were calculated. Radiographic measurements of 100 subjects were randomly selected to determine the intra- and inter-observer reliabilities using inter- and intra-class correlation coefficients (ICC). The spinal-pelvic parameters were compared among volunteers between different age and gender groups. The comparison was also made among various ethnic population. Results:The mean value was 23.7±7.1 kg/m 2 for BMI and 6.9%±2.5% (range, 0-18%) for ODI score. Each sagittal spinal-pelvic parameter was presented with mean value and standard deviationbased on age and gender. The ICCs of radiographic measurements ranged from 0.89 to 0.95, suggesting good to excellent intra- and inter-observer reliabilities. Significant differences were observed between males and females in multiple sagittal parameters (all P values <0.05). Compared to the male subjects, significantly higher values of PI (41.4° for male vs. 45.0° for female, P<0.001), PT (10.7° for male vs. 13.9° for female, P<0.001), PI-LL (-0.5° for male vs. 1.8° for female, P<0.001), and GT (10.9° for male vs. 13.5° for female, P<0.001) were documented in female subjects. Males had significantly higher values of LLL (28.6° for male vs. 26.6° for female, P<0.001) and LDI (0.68 for male vs. 0.63 for female, P<0.001). PI-LL, SVA, GT and TPA increased with aging from Group 40 s to Group 80 s, while LL, LLL and LDI decreased gradually, and TK decreased slowly with aging. Comparison of sagittal spinal-pelvic parameters between different ethnic subjects showed that Chinese adult population presented lower PI, SS, TK and LL as compared with American population; lower PI, SS and LL as compared with Japanese population. But the variation trend with aging tended to be consistent among different ethnic populations. Conclusion:Age- and gender-based normative values of sagittal spinal-pelvic alignment were established in asymptomatic Chinese adult population. Sagittal spinal-pelvic alignment varies with age and gender, and presented different compensation mechanism among different ethnic populations. Therefore, to achieve balanced sagittal alignment, age, gender and ethnicity should be take intoconsideration when planning spine correction surgery.
