Objective:To measure pancreatic fat deposition by magnetic resonance chemical shift imaging (CSI), and analyze the correlation between pancreatic fat deposition and pancreatic fistula after pancreaticoduodenectomy (PD).Methods:A retrospective analysis was conducted on the data of 55 patients who underwent PD in the Affiliated Hospital of Xuzhou Medical University from September 2021 to April 2024. Among them, 34 were male (61.8%) and 21 were female (38.2%), with the age of (63.5±12.0) years. The 55 patients included 17 cases (30.9%) of pancreatic ductal adenocarcinoma, 1 case (1.8%) of pancreatic serous cystadenoma, 2 cases (3.6%) of pancreatic mucinous cystadenoma, 1 case (1.8%) of pancreatic solid pseudopapillary tumor, 11 cases (20.0%) of ampullary carcinoma, 10 cases (18.2%) of common bile duct carcinoma, and 13 cases of other pathological types (such as high-grade intraepithelial neoplasia of the ampullary gland, duodenal adenocarcinoma, etc.) (23.6%). Before the operation, pancreatic fat deposition was measured by CSI and the fat fraction was calculated. With a fat fraction of 6.2% as the cut-off value, 55 patients were divided into the normal pancreas group (fat fraction ≤ 6.2%, n=29) and the fat pancreas group (fat fraction > 6.2%, n=26). The total hospitalization cost, postoperative hospital stay, biochemical leakage, grade B pancreatic fistula of the two groups were compared, and the correlation between pancreatic fat fraction and pancreatic fistula was analyzed. Result:The total hospitalization cost in the normal pancreas group was (91 527.3±19 118.4) yuan, and the postoperative hospital stay was 9.0 (8.0, 13.0) days, both of which were lower than those in the fatty pancreas group (107 772.4 ± 27 055.6) yuan and 11.0 (8.0, 22.0) days, and the differences were statistically significant ( t=-2.59, P=0.012; Z=-2.08, P=0.038). In the normal pancreas group, 8 cases (27.6%) of biochemical leakage and 1 case (3.4%) of grade B pancreatic fistula occurred after the operation. In the fat pancreas group, 10 cases (38.5%) of biochemical leakage and 8 cases (30.8%) of grade B pancreatic fistula occurred after the operation. There was no statistically significant difference in the incidence of biochemical leakage between the two groups ( χ2=0.74, P=0.391). The incidence of grade B pancreatic fistula after surgery in the adipose pancreas group was significantly higher than that in the normal pancreas group, and the difference was statistically significant ( χ2=5.61, P=0.018). The relationship between pancreatic body fat fraction and the occurrence of pancreatic fistula is correlated (the correlation coefficient was 0.334, 95% CI: 0.127-0.515, P=0.013) The relationship between the overall fat fraction of the pancreas and the occurrence of pancreatic fistula is correlated (the correlation coefficient was 0.472, 95% CI: 0.235-0.689, P<0.001). Conclusions:The incidence of grade B pancreatic fistula after PD in patients with a low fat fraction of the pancreas measured by CSI was lower than that in patients with a high fat fraction. Fat deposition in the pancreatic body and the pancreas as a whole is associated with the incidence of pancreatic fistula.

Objective:To design an assisted management system for medical consumables that integrated management logic of diagnosis related groups(DRG)for disease,so as to standardize the use for medical consumables and to strengthen regulatory efficiency.Methods:The system was designed by a microservices architecture,and the data fusion of business data,data of diagnosis and treatment,and DRG data was realized through constructed data lake.A knowledge graph of associated rule for medical consumables was established,and the intelligent analysis function included prediction for demand,usage optimization,and anomaly detection was provided to assist management decision-making on the basis of inference for historical data and knowledge,and multi-dimensional data queries.A rule engine was deployed at key clinical nodes for real-time compliance review and intelligent alerts.A DRG-based business management process was constructed to cover full lifecycle of consumables,including admission,procurement,warehousing,storage,requisition,usage billing,and traceability,so as to realize real-time monitoring and early warning for consumable costs at the DRG level.Six clinical doctors with 2-3 years of experience in using medical consumable were selected as test users from Tangdu Hospital of the Air Force Medical University,and they were randomly assigned into a system group and a control group,with 3 subjects in each group.The system group utilized the auxiliary management system for medical consumable to perform prediction for the demand of monthly procurement,and rationality verification of consumable.The control group relied on individual experience of doctors.The predicted monthly procurement demand for medical consumables,the accuracy of verifying rationality of using medical consumables between two groups were compared,and the efficiencies of two kinds of management modes also were compared.Results:The accuracy rate of system group was 89.17%in predicting the monthly procurement demand for medical consumables,and the rate of checking accuracy and the rate of checking comprehensiveness of system group were respectively 87.50%and 91.67%in verifying rationality of using medical consumables,which were significantly higher than those of control group,and the differences were significant(x2=6.62,1.96,16.73,P<0.05).The durations of predicting the demand for procurement,and verifying and testing the rationality of consumables in system group were significantly shorter than these in control group[(3.54±0.45)s,(2.23±0.15)s],and the differences were statistically significant(t=1.97,1.65,P<0.05).Conclusion:The medical consumables auxiliary management system integrated with DRG management logic can significantly enhance the accuracy of monthly demand prediction for consumables and the recall rate and precision rate of rationality verification for consumables usage,while greatly improving work efficiency.It is conducive to enhancing the standardized and refined supervision level of consumables usage.

The incidence of delayed chemotherapy-induced nausea and vomiting is relatively high among pediatric cancer patients. Nausea and vomiting symptoms can exacerbate physical and psychological burdens, potentially leading to aversion and reduced treatment adherence. This paper analyzes and summarizes delayed chemotherapy-induced nausea and vomiting in pediatric cancer patients, covering overview, influencing factors, assessment tools, and non-pharmacological interventions, aiming to provide insights for clinical prevention and intervention strategies targeting delayed chemotherapy-induced nausea and vomiting in pediatric patients.

Diabetes is a chronic disease that requires lifelong medication and long-term management. The longer the duration of the disease, the more likely it is to lead to progressive chronic complications affecting the eyes, kidneys, nervous system, and cardiovascular system. These complications may result in gradual functional decline or even organ failure, and may also trigger severe acute metabolic disorders. The cumulative financial burden on patients and their families can be substantial, giving rise to what is known as financial toxicity, which in turn may negatively affect patients' health outcomes. This review comprehensively explores the concept of financial toxicity in diabetic patients, including its assessment tools, influencing factors, and coping strategies. It also offers targeted suggestions aimed at informing the development of more scientific and effective systemic interventions, with the ultimate goal of improving treatment outcomes and quality of life for individuals living with diabetes.

BACKGROUND:In recent years,the development of liver organoids has made it a hot spot in the field of international liver disease research,but there is still no article on the bibliometric analysis of liver organoids. OBJECTIVE:To explore the hot trends in liver organoids in the last 20 years based on bibliometrics and visualization analysis. METHODS:We searched the articles about liver organoids in the Web of Science Core Collection from January 1,2002 to November 12,2022.Origin,Office,and CiteSpace software were used for bibliometrics and visualization analysis.We statistically analyzed the number of annually published articles,countries,institutions,authors,journals,and keywords of the articles by generating charts. RESULTS AND CONCLUSION:The number of articles,citation frequency,institutions and personnel involved in the research about liver organoids showed an overall upward trend in the last 20 years,indicating that the field was growing rapidly and attention was increasing.The USA had published the most papers and had the strongest influence in this field.Although it had invested a lot of time and energy,the number of papers published by a single research institution in the USA was not the highest among many research institutions.China was second only to the USA in the number of publications,with the Chinese Academy of Sciences and Fudan University leading the list.Utrecht University in the Netherlands was the institution with the most publications.Clevers H was the author with the highest number of articles.The article with the highest co-citation frequency was"Long-term culture of genome-stable bipotent stem cells from adult human liver".The main fields of study for liver organoids were Molecular Science,Biology,and Immunology.The most frequently occurring keywords were stem cell,in vitro,and culture.The research hotspots in the liver organoids field were mainly focused on in vitro stem cell three-dimensional culture,differentiation and gene expression.

Objective To explore the effect of acute caffeine and theanine supplementation on coordi-nation and aerobic performance in mentally fatigued soccer players.Methods A randomized crossover de-sign was employed with 15 male amateur soccer players.Participants underwent three different interven-tions—caffeine(caffeine group),theanine(theanine group),and placebo(placebo group)—with a one-week washout period between each intervention.After each supplementation,participants performed a 45-minute Stroop task to induce mental fatigue,followed by a speed dribbling test(SDT)and the 30-15 intermittent fitness test(30-15IFT)to assess coordination and aerobic performance,respectively.Mea-surements included visual analog scale for mental fatigue(VAS-MF),motivation(VAS-MO),Brunel mood scale for fatigue(BRUMS-F)and vigor(BRUMS-V)pre-and post-Stroop task,response time(RT),response accuracy(ACC),average heart rate(HRave)during Stroop,mental exertion(VAS-ME)post-Stroop,rating of perceived exertion(RPE),HRave,and peak heart rate(HRpeak)during SDT and 30-15IFT.All data were analyzed using repeated measures ANOVA.Results The change in VAS-MF(ΔVAS-MF)before and after the Stroop task was lower in the caffeine group compared to the placebo group(P=0.064),while the theanine group showed similar ΔVAS-MF to the latter group(P=0.999).Both the caffeine and theanine groups had significantly faster RT(P=0.003 and 0.033,respectively)and higher ACC(P=0.006 and 0.033,respectively)during the Stroop task compared to the placebo group.Moreover,coordination performance in both the caffeine and theanine groups was better than the placebo group(P=0.096 and 0.078,respectively).Meanwhile,aerobic performance in the caffeine group was significantly better than the placebo group[time to exhaustion(TTE):P=0.012;last stage ve-locity of 30-15IFT(VIFT):P=0.007;maximal oxygen uptake(VO2max):P=0.008],whereas no significant differences were found between the theanine group and the placebo group in the aerobic performance(TTE:P=0.999;VIFT:P=0.999;VO2max:P=0.999).Conclusion Both acute caffeine and theanine supple-mentation can mitigate the negative effect of mental fatigue on coordination performance in soccer play-ers.Additionally,acute caffeine supplementation can also alleviate the negative impact of mental fa-tigue on aerobic performance.
