Cancer has become one of the most significant diseases threatening human life and health. In 2022, there were 19.97 million new cancer cases and 9.74 million cancer-related deaths worldwide, imposing a heavy burden on society. A systematic and comprehensive understanding of the cancer burden is the cornerstone for formulating effective prevention and control strategies. Open-source databases, represented by the GLOBOCAN database and the Global Burden of Disease (GBD) database, provide critical support for obtaining the latest cancer burden data, identifying key areas for prevention and control, guiding screening and early diagnosis and treatment, and evaluating the effectiveness of intervention measures. However, the field of cancer big data also faces challenges, such as insufficient data standardization and inadequate privacy protection mechanisms. In the future, while ensuring patient privacy and security, efforts should be made to further improve data quality, promote data sharing, enhance the equity of cancer prevention and treatment resources, and strengthen international collaboration. These measures will reasonably advance the precision and scientific development of cancer prevention and control strategies, with the aim of reducing the cancer burden and contributing to global health and well-being.

BACKGROUND: Temozolomide (TMZ) resistance is a significant challenge in treating glioblastoma (GBM). Collagen remodeling has been shown to be a critical factor for therapy resistance in other cancers. This study aimed to investigate the mechanism of TMZ chemoresistance by GBM cells reprogramming collagens. METHODS: Key extracellular matrix components, including collagens, were examined in paired primary and recurrent GBM samples as well as in TMZ-treated spontaneous and grafted GBM murine models. Human GBM cell lines (U251, TS667) and mouse primary GBM cells were used for in vitro studies. RNA-sequencing analysis, chromatin immunoprecipitation, immunoprecipitation-mass spectrometry, and co-immunoprecipitation assays were conducted to explore the mechanisms involved in collagen accumulation. A series of in vitro and in vivo experiments were designed to assess the role of the collagen regulators prolyl 4-hydroxylase subunit alpha 1 (P4HA1) and yes-associated protein (YAP) in sensitizing GBM cells to TMZ. RESULTS: This study revealed that TMZ exposure significantly elevated collagen type I (COL I) expression in both GBM patients and murine models. Collagen accumulation sustained GBM cell survival under TMZ-induced stress, contributing to enhanced TMZ resistance. Mechanistically, P4HA1 directly binded to and hydroxylated YAP, preventing ubiquitination-mediated YAP degradation. Stabilized YAP robustly drove collagen type I alpha 1 ( COL1A1) transcription, leading to increased collagen deposition. Disruption of the P4HA1-YAP axis effectively reduced COL I deposition, sensitized GBM cells to TMZ, and significantly improved mouse survival. CONCLUSION P4HA1 maintained YAP-mediated COL1A1 transcription, leading to collagen accumulation and promoting chemoresistance in GBM.

Food-derived bioactive peptides (FBPs), particularly those with ten or fewer amino acid residues and a molecular weight below 1300 Da, have gained increasing attention for their safe, diverse structures and specific biological activities. The development of FBP-based functional foods and potential medications depends on understanding their structure‒activity relationships (SARs), stability, and bioavailability properties. In this review, we provide an in-depth overview of the roles of FBPs in treating various diseases, including Alzheimer's disease, hypertension, type 2 diabetes mellitus, liver diseases, and inflammatory bowel diseases, based on the literature from July 2017 to Mar. 2023. Subsequently, attention is directed toward elucidating the associations between the bioactivities and structural characteristics (e.g., molecular weight and the presence of specific amino acids within sequences and compositions) of FBPs. We also discuss in silico approaches for FBP screening and their limitations. Finally, we summarize recent advancements in formulation techniques to improve the bioavailability of FBPs in the food industry, thereby contributing to healthcare applications.

BACKGROUND:Talus cartilage injury is a common motor system disease.This type of injury will affect the patient's daily life and work ability,and may worsen the condition if left untreated.Surgical treatment is commonly used,but the selection of surgical methods and the evaluation of medium-and long-term follow-up results have always been difficult clinical problems. OBJECTIVE:To explore the influence of T1ρ technique on the range of quantitative evaluation of talus osteochondral injury on the choice of surgical method and the results of medium-and long-term follow-up. METHODS:A total of 154 patients with osteochondral injury of talus admitted to The Second Hospital of Tangshan from January 2019 to August 2022 were retrospectively selected as the study subjects.The lesion site of talus was examined by MRI before operation,and the T1ρ and T2 values of different types were compared.Different surgical methods were selected according to the different T1ρ values.Group A(n=73)was treated with microfracture surgery with T1ρ<45 ms;group B(n=81)was treated with autogenous bone and cartilage transplantation with T1ρ≥45 ms.The general clinical characteristics and curative effects of patients under different surgical methods were compared;the important factors of postoperative recurrence were analyzed by multivariate Logistic regression,and the relationship between T1ρ value and postoperative recurrence was analyzed by restricted cubic spline graph,y=1-1/(1+e-z)regression equation to build a prediction model.The stability of the model was verified by cross-checking method. RESULTS AND CONCLUSION:(1)Classification of talus osteochondral injury in 154 patients(type Ⅰ:36 cases;type Ⅱ:37 cases;type Ⅲ:40 cases;type Ⅳ:41 cases),T1ρ and T2 values of the four groups were statistically significant(P<0.05);pairwise comparison was also statistically significant(all P<0.05).(2)After treatment of 154 patients,7 cases(4.6％)had local swelling,3 cases(2.0％)had pain aggravation,and 5 cases(3.3％)had wound infection.There were 2 cases(1.3％)with poor cartilage healing.(3)After treatment,there were statistically significant differences between groups A and B in terms of American Orthopaedic Foot&Ankle Society score,visual analog scale score,plantar flexor motion range,dorsoextension motion range,subchondral bone marrow edema volume,interleukin-6,interleukin-8,C-reactive protein,procalcitonin,platelet-derived growth factor,transforming growth factor-β1,and efficacy(P<0.05).The total effective rate of group B(90％)was higher than that of group A(85％)(P<0.05).(4)Age(OR=1.589,95％CI:0.305-1.252,P=0.036),interleukin-6(OR=1.737,95％CI:0.974-5.254,P=0.049),interleukin-8(OR=1.385,95％CI:1.066-4.355,P=0.034),C-reactive protein(OR=1.957,95％CI:1.323-2.178,P=0.035),transforming growth factor-β1(OR=1.459,95％CI:0.897-2.455,P=0.038),T1-ρ(OR=1.687,95％CI:0.854-3.321,P=0.026),T2(OR=1.843,95％CI:0.657-2.454,P=0.036),complications(OR=1.719,95％CI:0.654-3.464,P=0.019),and classification of osteochondral injury of talus(OR=3.789,95％CI:1.023-5.897,P=0.028)were independent risk factors for postoperative recurrence.Microfracture surgery(OR=0.751,95％CI:0.321-1.264,P=0.012)and autogenous bone and cartilage grafting(OR=0.649,95％CI:0.246-1.356,P=0.023)were independent protective factors for recurrence after medium-and long-term follow-up.(5)When T1ρ value≤35 ms,the risk of postoperative recurrence decreased rapidly,and when T1ρ value>35 ms,the risk of postoperative recurrence increased rapidly.(6)Further stepwise regression analysis showed that these nine risk factors were most closely associated with postoperative recurrence,and the formula for postoperative recurrence was obtained.The probability of postoperative recurrence was calculated using the regression equation.When P=0.75,the maximum value of Jorden index was 77.728,indicating that the model has a better prediction effect.(7)It is indicated that the quantitative evaluation of T1ρ before operation can effectively guide the selection of surgical methods,improve the success rate of surgery and the quality of life of patients.

Objective:To explore the genetic etiology of a fetus with cryptophthalmos detected by prenatal ultrasonography.Methods:A fetus undergoing induced labor at 32nd gestational week due to absence of bilateral eye fissures detected by prenatal ultrasonography in January 2017 was selected as the study subject. Umbilical cord blood sample from the fetus and peripheral blood samples from its parents were collected for the extraction of genomic DNA. Pathogenic variants were screened through whole exome sequencing (WES) and verified by Sanger sequencing. Pathogenicity of candidate variants was verified by bioinformatic analysis and protein structure simulation. Based on the results of genetic testing, prenatal diagnosis was provided to the couple upon their subsequent pregnancy.Results:The couple had four adverse pregnancies previously. The aborted fetus was the fifth, with fused bilateral upper and lower eyelids, poorly developed eyeballs, adhesion of the cornea with the upper eyelid, low-set ears, and abnormal plantar creases, and was diagnosed with cryptophthalmos. WES and Sanger sequencing revealed that the fetus has harbored compound heterozygous variants of the FREM2 gene, namely c. 4537G>A (p.D1513N) and c.7292C>T (p.T2431M). Both variants were unreported associated with cryptophthalmos previously. Protein structure simulation showed that they may lead to loss of hydrogen bonds in the protein product. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be likely pathogenic (PM1_Supporting+ PM2_Supporting+ PM5+ PP3+ PP4; PM2_Supporting+ PM3+ PP3+ PP4). The mother was performed prenatal diagnosis in her sixth pregnancy based on the variants detected in this family, and delivered a daughter with normal phenotype. Conclusion:The FREM2: c. 4537G>A and c. 7292C>T compound heterozygous variants probably underlay the pathogenesis of cryptophthalmos in this fetus. Above finding has enriched the mutational spectrum of the FREM2 gene.

In recent years, the incidence of cancer in China has been increasing steadily. Advancing primary prevention measures for cancers could be an effective strategy to curb this trend. Diet has been considered a modifiable and shared risk factor for various cancers. Studying dietary patterns, with consideration of the interactions between foods and nutrients, has a practical implication for cancer prevention. This study provided an overview of dietary pattern extraction methods, summarized the research findings on the association between dietary patterns and cancers in the digestive system, respiratory system, and genitourinary system, and elucidated the potential mechanisms underlying these associations, in order to provide scientific references for future research in this field.

Objective:This paper provides a brief overview of the epidemiology of colorectal cancer in China and around the world, and discusses how to prevent colorectal cancer to reduce its disease burden.Method:Using the official database of GLOBOCAN 2020, the China Cancer Registry Annual Report compiled by the National Cancer Center, and data from CONCORD-3.Data management was performed by Microsoft Excel 2016 and R 4.2.1 Relevant graphs were generated using the ggplot2 package for result visualization.Result:An estimated 1 931 590 people were diagnosed with colorectal cancer worldwide in 2020 with an age-standardized incidence rate of 19.5 per 100 000. There were about 935 173 deaths caused by colorectal cancer internationally, with an age-standardized mortality rate of 9.0 per 100 000. Overall, colorectal cancer was the fourth most commonly diagnosed cancer and the third leading cause of cancer-related death worldwide in 2020. In China, the age-standardized incidence rate and mortality rate of colorectal cancer was 17.3 per 100 000 and 7.8 per 100 000, respectively. Gender differences in trends were observed, with a decreasing trend in incidence and mortality among females and an increasing trend in incidence and mortality among males. The primary risk factors for colorectal cancer include age, genetic factors, gastrointestinal disorders, dietary habits, and lifestyle et al.Conclusions:Colorectal cancer poses a significant burden globally and in China. The occurrence of colorectal cancer is closely related to physiology, genetics, behavioral habits, lifestyle, and disease factors. To better control the colorectal cancer burden with the lowest cost, specific measures should be taken to reduce exposure to established risk factors. By combining the disease prevention and control strategies of tertiary prevention in China with the characteristic factors of colorectal cancer, the incidence and mortality of colorectal cancer may be effectively controlled.

Background::Digestive system cancers constitute a significant number of cancer cases, but their burden is not uniform. As Global Cancer Observatory (GLOBOCAN) 2022 has recently updated its estimates of cancer burden, we aimed to investigate the burden of six major digestive system cancers both worldwide and in China, along with geographical and temporal variations in cancer-specific incidence and mortality.Methods::We extracted data on primary cancers of the esophagus, stomach, colorectum, liver, pancreas, and gallbladder from the GLOBOCAN database for 2022. Age-standardized incidence and mortality rates were calculated and stratified by sex, country, region, and human development index (HDI). We used the 2022 revision of the World Population Prospects (United Nations) to obtain demographic data for various age groups in China from 1988 to 2012 and used the joinpoint model and the average annual percentage change (AAPC) to analyze cancer incidence trends in China.Results::In 2022, the estimated global incidence of digestive system cancers reached 4,905,882, with an estimated 3,324,774 cancer-related deaths. Colorectal cancer was most prevalent in terms of incidence and mortality. There was a significant correlation between the burden of gastrointestinal cancers and country HDI. From 1988 to 2012, the incidence of esophageal, gastric, and liver cancers declined in China, whereas colorectal and pancreatic cancer incidences continued to increase. By 2050, colorectal and liver cancers are projected to remain the leading cancer types in China in terms of incidence and mortality, respectively.Conclusions::Digestive system cancers remain a significant public health challenge globally and in China. Although progress has been made in the prevention and control of some cancers, the burden of digestive system cancers persists. The implementation of tertiary prevention strategies must be intensified to reduce the incidence and mortality of digestive system cancers, mitigating their impact on public health.
