Liver metastases is the most common distant metastases of pancreatic neuroendocrine neoplasms, and it is also one of the main factors affecting the prognosis of patients. With the development of treatment technology and the rise of a multidisciplinary treatment model, the treatment plan for patients with liver metastases has gradually evolved into a comprehensive treatment plan including surgery, intervention, medicine, and radiation therapy. Radical surgery is still the only treatment currently available to cure patients with pancreatic neuroendocrine tumors and liver metastases. Very few selected patients can also benefit from liver transplantation. For most patients who are unable to undergo surgery can choose intervention, medicine and radiation therapy which can improve the patient′s prognosis to a certain extent. Targeted therapy and immunotherapy have good development prospects, and further research is still needed. With multidisciplinary treatment, individualized treatment can help patients obtain the best treatment results.

Objective:To investigate the value of Gd-EOB-DTPA-enhanced MRI in evaluating liver function and predicting the risk of post-hepatoectomy liver failure in patients with major resection of liver cancer.Methods:A total number of 212 patients were included from June 2016 to June 2019 at Department of General Surgery, Peking University Third Hospital with a retrospectively collected data.All patients underwent Gd-EOB-DTPA-enhanced MRI for diagnosis and preoperative evaluation of liver function.There were 135 males and 77 females, with age of (63.1±10.3) years old (range: 18 to 86 years old) . Relative enhancement ratio (RER) of the region of interest on Gd-EOB-DTPA-enhanced MRI was acquired by two independent researcher and then conducted the comparison of RER among the patients with or without post-hepatoectomy liver failure (PHLF) .Preoperative evaluation demonstrated that 141 cases infected by hepatitis virus, 128 cases with hepatitis B alone and 11 cases with hepatitis C alone, 2 cases had both of hepatitis B and C, and all patients were grade A judged by Child-Pugh score. The relationship between RER and PHLF was evaluated by Pearson correlation analysis and the diagnostic value of RER in predicting PHLF was test by receiver operating characteristic curve.Results:PHLF occurred in 42 patients according to ISGLS standard. Among them, 31 cases had level A liver failure, 9 cases had level B liver failure and 2 had level C failure. There was a significant correlation between RER and overall level of PHLF and RER was also significantly associated with severe B to C level of PHLF ( P<0.05) .The further receiver operating characteristics curve analysis showed that the diagnostic accuracy of RER on overall PHLF was 0.818 (sensitivity 72.9%, specificity 83.3%, cut-off value 73.5%, 95 %CI: 0.75 to 0.887) and on severe PHLF was 0.924 (sensitivity 97.0%, specificity 90.9%, cut-off value: 61.5%, 95 %CI: 0.79 to 0.90) . Conclusion:For patients who planned to undergo major resection of liver cancer, preoperative Gd-EOB-DTPA-enhanced MRI can help with the assessment of liver function and predicting the risk for post-hepatectomy liver failure.

The incidence of pancreatic ductal adenocarcinoma(PDAC) is increasing year by year among digestive system tumors.It has a high degree of malignancy and a poor prognosis.Its five-year survival rate is less than 8%.Traditional radiotherapy and chemotherapy are not sensitive to pancreatic cancer,so finding a new drug is the future hope for pancreatic cancer.In recent years,molecular targeted therapy has made obvious progress in diseases such as hematological malignancies,non-small cell lung cancer and melanoma,and a large number of targets have been tried in pancreatic cancer, for example, gene mutation targets, important signaling pathway targets, receptor targets, etc. The use of these targeted drugs alone or in combination has shown good results in preclinical models and some clinical trials, and some treatment have been standardized for patients with pancreatic cancer, while other options that have not yet been tested in large-scale clinical trials also offer a variety of potential possibilities for future targeted treatments for pancreatic cancer.

Objective: To investigate the doseresponse relationship between the risk of elevated blood pressure and body mass index (BMI) in primary and secondary school students in Shibei District, Qingdao, so as to provide a reference for precise interventions of elevated blood pressure. Methods: Statistical analysis was conducted on the health examination data of 92 091 primary and secondary school students in Shibei District, Qingdao, in 2022. Overweight and obesity were assessed using the standards from the Screening for Overweight and Obesity among Schoolaged Children and Adolescents, and blood pressure levels were evaluated using the Reference of Screening for Elevated Blood Pressure among Children and Adolescents Aged 7-18 Years. The relationship between BMI and elevated blood pressure was examined using analysis of variance, Chisquare test, multifactorial Logistic regression, and a combination of restricted cubic spline after data cleaning. Results: Based on the standardized scores under different age and gender, BMI was classified into 5 categories. Compared with the group of BMIZ scores 0-<1, the risk of developing high blood pressure gradually decreased with BMIZ scores (OR=0.55, 0.53, P<0.05). Conversely, the risk of developing high blood pressure increased with increasing BMIZ scores (OR=1.90, 3.71, P<0.05). Stratified analyses showed that BMI was positively associated with elevated blood pressure by gender (male, female), age (aged 7-8, 9-11, 12-14, 15-16), and waisttohip ratio (≤0.83, >0.83) (OR=1.18, 1.19, 1.15, 1.22, 1.19, 1.18, 1.19, 1.18, P<0.01). There were multiplicative interactions between BMI and gender, between BMI and age, between BMI and waisttohip ratio (OR=1.53, 1.08, 2.31, P<0.01). Restricted cubic spline analysis showed that as BMI levels increased, the risk of developing elevated blood pressure showed a nonlinear increasing trend in both the 7yearold and the 10 to 16yearold (χ2=27.56, 10.69, 6.10, 27.26, 18.32, 25.71, 10.53, 6.14, P<0.05). Conclusions The risk of elevated blood pressure in primary and secondary school students increases with BMI, showing a nonlinear doseresponse relationship. The blood pressure should be monitored regularly, and comprehensive and effective measures should be implemented to control elevated blood pressure in children and adolescents.
