Objective To observe the value of MRI radiomics model for predicting postoperative prognosis of moderate carpal tunnel syndrome(CTS).Methods A total of 126 patients with moderate CTS who underwent endoscopic release and fat-suppressed proton density weighted imaging(PDWI)before operation were retrospectively enrolled.The patients were divided into good prognosis group(n=80)and poor prognosis group(n=46)based on postoperative functional evaluation,also randomly divided into training set and validation set at a ratio of 7∶3.Volume of interest(VOI)of the median nerve was obtained through delineating ROI of the affected wrist on fat suppressed PDWI.Radiomics features were extracted,and those associated with postoperative prognosis of CTS were screened in training set.Clinical prediction model,radiomics model and combined model of these two were established,and the predictive efficacy of the models were evaluated and compared according to the area under the curve(AUC)of receiver operating characteristic(ROC)curve.Results Patients in poor prognosis group were older than in good prognosis group(P＜0.05).A clinical model was constructed based on age.The radiomics model was constructed based on 6 radiomics features associated with postoperative prognosis of CTS,with predictive efficacy(AUC=0.872)higher than that of clinical model(AUC=0.604,P＜0.05)but not significantly different with that of the combined model(AUC=0.905,P＞0.05).Conclusion MRI radiomics model could be used to effectively predict postoperative prognosis of moderate CTS.

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.

Objective To explore the diagnostic value of MRI radiomics analysis in mild carpal tunnel syndrome(CTS).Methods Seventy patients with mild CTS and 86 healthy volunteers who underwent wrist MRI examination were retrospectively selected.MRI fat-suppressed proton density weighted imaging(PDWI)were imported into 3D Slicer software,and the region of interest(ROI)delineation was performed by two radiologists independently.The 830 radiomics parameters were extracted,including first-order fea-tures,shape features,texture features,and wavelet-transform features.Radiomics parameter selection was performed through observer intraclass correlation coefficient(ICC),correlation analysis,and multivariate logistic regression.Five diagnostic models were estab-lished,including logistic regression,support vector machine,naive Bayes,decision tree,and random forest.Receiver operating charac-teristic(ROC)curve was used to analyze the diagnostic efficiency of the models.Results Seven radiomics features were selected for inclusion in the diagnostic models.The logistic regression model demonstrated the best performance,with an area under the curve(AUC)of 0.91[95%confidence interval(CI)0.86-0.96],a sensitivity of 88.63%,and a specificity of 89.00%in the training group.In the test group,the AUC was 0.92(95%CI 0.85-0.97),with a sensitivity of 90.48%and a specificity of 84.62%.Conclusion MRI radiomics analysis can be used to diagnose mild CTS,and the logistic regression model demonstrates superior diagnostic per-formance.

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.

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.

Objective:To analyze the prognostic factors affecting salvage liver transplantation (SLT).Methods:The clinical data of 97 patients undergoing liver transplantation in the Ningbo Medical Centre Lihuili Hospital from January 2012 to May 2022 were retrospectively analyzed, including 84 males and 13 females, aged (53.6±7.4) years. Among them, 33 patients underwent primary liver transplantation (PLT) and 64 underwent SLT. SLT patients were subdivided into the groups within the Milan criteria (SLT-A, n=35) and beyond the Milan criteria (SLT-B, n=29), according to whether the Milan criteria were met at first hepatectomy. Clinicopathological and prognostic data were subsequently analyzed. Results:The tumor number ( χ2=16.03, P<0.001), microvascular invasion (MVI) ( χ2=10.97, P=0.004), recurrence rate ( χ2=9.31, P=0.010), recurrence-free survival (RFS, F=14.05, P=0.001) and overall survival (OS, F=17.27, P<0.001) were significantly different among the three groups. RFS ( P=0.047) and OS ( P=0.012) in PLT group were better than those in SLT-B group. RFS ( P=0.007) and OS ( P=0.024) in SLT-A group were also better than those in SLT-B group. The multivariate analysis indicated that beyond the Milan criteria at first hepatectomy was an independent risk factor for RFS ( HR=4.378, 95% CI: 1.393-13.756, P=0.011) and OS ( HR=5.391, 95% CI: 1.428-20.352, P=0.013) in patients undergoing SLT, and MVI positive ( HR=4.042, 95% CI: 1.137-14.368, P=0.031) was an independent risk factor for RFS in patients undergoing SLT. Conclusion:Patients beyond the Milan criteria at first hepatectomy and MVI positive showed a poorer prognosis after SLT. Whether the Milan criteria should be the gold standard for SLT as well as for PLT needs further study.
