Objective To investigate the current nursing practice of nurses specializing in nutritional support in ICUs and analyze their influencing factors in order to improve the training program and promote the development of standardized and precise nursing practice.Methods Convenience sampling method was used to select nutritional support nurses in ICUs in 29 provinces(autonomous regions and municipalities)from October 2023 to March 2025,and the self-developed questionnaire on nursing practice behaviors of nutritional support nurses in ICUs was used to conduct the survey.SPSS 21.0 software was used for descriptive analysis and multiple linear regression analysis.Results A total of 774 questionnaires were distributed,and 766 valid questionnaires were collected,with a recovery rate of 98.97％,and the score of the questionnaire on nursing practice behaviors of nurses specializing in nutritional support in ICU was(90.41±1 1.82).The results of multiple linear regression analysis showed that gender,presence of a nutritional support nursing team in the hospital,a standardized process of nutritional support nursing in the department,clear positional responsibilities of the nutritional support nursing team members,and inclusion of the nutritional support status of the patients in the quality management of the department were the factors influencing the nursing practice behavior scores of the nurses specializing in nutritional support in ICUs(P＜0.05).Conclusion Nurses in the ICUs have a high level of nursing practice behavior,but there is a need for further standardization in parenteral nutrition infusion and monitoring of complications.ICU nursing managers should formulate improvement strategies to address the weaknesses of clinical practice,strengthen nutritional support training,and improve the quality management program,and further improve the practical ability of nurses specializing in nutritional support.

Objective To study the death status of pancreatic cancer among residents in Xuhui district, Shanghai, from 1992 to 2021, and analyze its trends of change, so as to provide evidence for the prevention and treatment of pancreatic cancer. Methods Based on the database of Shanghai death registration system from 1992 to 2021, the crude mortality rate, standardized mortality rate, age-specific mortality rate and other indicators of pancreatic cancer among registered residents in Xuhui district were calculated. The Joinpoint software was used to analyze the trends of average annual percent change (AAPC) of pancreatic cancer mortality rate, and the age-period-cohort model was used to analyze the age effect, period effect and birth cohort effect pairs significant changes in pancreatic cancer mortality. Results In 2021, the mortality rate of pancreatic cancer in Xuhui district, Shanghai, ranked fourth among malignant tumors, and the winning rate and world standard rate of the whole population, males and females were 8.34/100 000 (8.81/100 000, 7.98/100 000) and 7.28/100 000 (7.69/100 000, 6.96/100 000), respectively, with males higher than females. AAPC of crude mortality rate and the standardized (6) mortality rate were higher in males than that in females. The age-specific mortality rate increased with the increase of age, and the highest mortality rate was found in 60-84 years old group. The age-period-cohort model showed that from 1992 to 2021, the annual net shift of pancreatic cancer mortality among the whole population, male and female residents in Xuhui district, Shanghai, was 1.22%, 1.58%, 1.15% (P=0.20, 0.19, 0.45) respectively, and the time trend was not significant. From the perspective of age effect, the risk of death from pancreatic cancer in the whole population and with age deviation in males had an obvious trend with increasing age (P<0.05), while the age effect in females had no obvious trend. From the perspective of period effect, no period deviation was significant in the whole population, males and females (P>0.05). In terms of cohort effects, there were significant differences in the whole population and the male cohort deviations(P<0.05). No significant cohort effect was observed in the female population. Conclusions The mortality rate of pancreatic cancer among registered residents in Xuhui district, Shanghai from 1992 to 2021, was on the rise, especially in the 60-84 years old group and male. The prevention and control of pancreatic cancer needs to develop effective epidemic prevention measures for corresponding populations.

Objective:To analyze the association between remnant cholesterol (RC) and the risk of atherosclerotic cardiovascular disease (ASCVD) in community population in Shanghai.Methods:Using baseline and follow-up data from the Shanghai Suburban Adult Cohort and Biobank, individuals with ASCVD (including coronary heart disease, stroke, myocardial infarction, and peripheral artery disease) at baseline were excluded. A Cox proportional hazards regression model was employed to analyze the relationship between RC and ASCVD risk and the association under different LDL-C levels.Results:A total of 57 281 participants were included, with a median follow-up of 5.61 person-years. During the follow-up, 1 436 ASCVD events (2.51%) were recorded. After adjusting for potential confounders, individuals with moderate ( HR=1.18, 95% CI: 1.03-1.36) or high RC levels ( HR=1.32, 95% CI: 1.15-1.51) had an increased risk of ASCVD. The association was stronger in participants younger than 60 years-old (interaction P=0.048). Participants with RC ≥0.97 mmol/L and LDL-C <3.40 mmol/L demonstrated a 19% ( HR=1.19, 95% CI: 1.06-1.35) increased risk of ASCVD. When RC ≥0.97 mmol/L and LDL-C ≥3.40 mmol/L, ASCVD risk increased by 42% ( HR=1.42, 95% CI: 1.21-1.67). Conclusions:Elevated RC increases ASCVD risk, regardless of LDL-C levels. RC can serve as a valuable predictor and intervention target for ASCVD.

Objective:To explore the efficacy and safety of mitotane in adrenal cortical carcinoma (ACC) at high risk of recurrence.Methods:A prospective observational study was designed from September 2022 to November 2023. ACC patients undergoing surgery with high recurrence risk (positive margin or Ki-67 index >10% or capsule rupture or large size or high-grade ACC) in Peking Union Medical College Hospital were enrolled in this study. All patients started mitotane treatment within 3 months after surgery, with a dose of 1.5 g/d, increased by 0.5 g per week. Once the dose reached 3 g/day, adjustments were made based on blood concentration levels. All patients received mitotane therapy for at least 1 year, and CT was performed every 12 weeks to evaluate the efficacy. The primary endpoint was 1-year progression-free survival (PFS) and safety. The efficacy was analyzed by Kaplan-Meier method for survival, and the occurrence of treatment-related adverse events was summarized.Results:A total of 12 ACC patients at high risk of recurrence were screened, comprising 6 males and 6 females. Tumors were located on the left side in 8 patients, on the right in 3, and bilaterally in 1. Five patients were classified as ENSAT stageⅡ, while 7 were classified as ENSAT stage Ⅲ. The maximum diameter of tumor was (9.07 ± 2.86) cm; the median age at diagnosis was 48 (35, 51) years, and the median Ki-67 index was (28.9 ± 16.1)%. The median time from surgery to initiation of mitotane therapy was 31 (23.0, 43.2) days, and 9 patients had blood drug concentrations of 14-20 mg/L. The median follow-up time was 16.7 (12.4, 25.2) months. At 1 year after mitotane therapy, 10 (83.8%) patients were still in disease-free survival state, with a median mitotane PFS of 27.6 months (95% CI 16.4-not reached). All ACC patients experienced 1-2 grade adverse events after taking mitotane. One patient (8.3%) experienced grade 3 adverse event, including the increasing of alanine aminotransferase and aspartate aminotransferase, as well as anorexia. No grade 4-5 adverse events occurred. The most common adverse events were gastrointestinal symptoms (10 cases), including nausea, vomiting, anorexia, and diarrhea, followed by liver function damage(9 cases) and neurotoxicity(4 cases). Conclusions:Mitotane has shown the prospect of improving the prognosis of ACC patients at high risk of recurrence after surgery. Because of its serious toxic and side effects, it is necessary to monitor its blood concentration to adjust the dosage, and take measures for adverse reactions to ensure the safety of patients.

Objective:To investigate the genetic mutation characteristics of patients with bilateral macronodular adrenocortical disease（BmacAD）and to analyze the clinical phenotypes and adrenal nodule transcriptomic profiles associated with different genotypes.Methods:This retrospective study analyzed the clinical data of 37 patients diagnosed with BmacAD by clinical and pathological assessment who underwent surgery at Peking Union Medical College Hospital from January 2001 to December 2024. Data included symptoms and signs related to hypercortisolism，24-hour urinary free cortisol，plasma adrenocorticotropic hormone（ACTH），and overnight low-dose dexamethasone suppression test results. Whole-exome sequencing（WES）was performed on frozen adrenal hyperplasia tissue samples from surgical specimens and matched frozen residual blood samples for all patients to screen for germline and somatic mutations. Sanger sequencing was used to validate some of the identified mutations. The relation between genetic mutations and clinical features was analyzed. Transcriptome sequencing of the hyperplastic tissues was conducted，and unsupervised clustering，differential gene expression analysis，and pathway enrichment analysis were used to compare the transcriptomic profiles of patients with different genotypes.Results:A total of 37 cases were included（23 males and 14 females），aged between 31?68 years old. Among the patients with available clinical data，most exhibited signs of hypercortisolism，including hypertension（100.0%，36/36），diabetes（50.0%，18/36），and centripetal obesity（55.9%，19/34），accompanied by relevant endocrine abnormalities such as elevated 24-hour urinary free cortisol（79.4%，27/34），suppressed ACTH（77.8%，28/36），and a positive overnight low-dose dexamethasone suppression test（45.2%，14/31）. WES and Sanger sequencing revealed that ARMC5 gene mutations were the most common. Among the 37 patients，33（89.2%）had ARMC5 germline mutations，and 31（83.8%）concurrently harbored ARMC5 somatic mutations，including 3 cases of loss of heterozygosity. Two patients without detectable ARMC5 mutations both carried a somatic p.S45P mutation in the CTNNB1 gene and neither had typical manifestations of hypercortisolism. Transcriptome sequencing results suggested that patients with ARMC5 mutations had an upregulation of pathways related to steroid secretion.Conclusions:The majority of BmacAD patients present with typical manifestations of hypercortisolism，while a minority exhibit only mild autonomous cortisol secretion without obvious symptoms. Biallelic inactivation of the ARMC5 gene is the primary genetic driver of this disease，leading to more severe hypercortisolism by upregulating steroid hormone secretion. CTNNB1 mutations may be involved in the pathogenesis of some patients without ARMC5 mutations.

Objective:To explore the differences in clinicopathological features and prognosis between conventional adrenocortical carcinoma（ACC）and oncocytic ACC.Methods:The clinical and pathological data of patients with conventional ACC and oncocytic ACC who were admitted to Peking Union Medical College Hospital from March 2012 to Fabruary 2025 were retrospectively analyzed. Differences in clinical and pathological characteristics between the two groups were compared. Survival curves were plotted using the Kaplan-Meier method，and differences in survival rates were compared using the log-rank test.Results:The conventional ACC group comprised 137 cases，with a mean age of（47.5 ± 12.6）years and 37.2%（51/137）being male. The oncocytic ACC group included 22 cases，with a mean age of（49.1 ± 15.3）years and 59.1%（13/22）being male. No statistically significant differences were observed in age or gender distribution between the two groups（ P > 0.05）. The conventional ACC group exhibited a significantly higher prevalence of classic Cushing’s syndrome symptoms compared to the oncocytic ACC group［35.2%（45/128）vs. 5.3%（1/19）； χ2 = 6.876， P < 0.01］. Additionally，the proportion of hypertension was higher in the conventional ACC group［49.2%（65/132）vs. 22.2%（4/18）； χ2 = 5.319， P < 0.05］，whereas the prevalence of adrenal sex characteristics was lower［22.0%（28/127）vs. 63.2%（12/19）； χ2 = 14.043， P < 0.01］. The Ki-67 proliferation index was significantly higher in conventional ACC patients［20%（10%，40%）vs. 12%（9%，20%）； Z = -2.113， P < 0.05］. Furthermore，the conventional ACC group demonstrated a lower 5-year overall survival rate than the oncocytic ACC group（44.5% vs. 67.3%， P < 0.05）. Conclusions:Conventional ACC patients have a higher proportion of Cushing’s symptoms and hypertension，and oncocytic ACC patients have a higher proportion of adrenal sexual characteristics abnormalities. The prognosis of oncocytic ACC is better than that of conventional ACC.

Objective:To develop an ultrasound multi-view fusion recognition model and evaluate its clinical value in diagnosing fetal conotruncal defects (CTD).Methods:This prospective study collected cardiac ultrasound images from fetuses at 20-32 weeks of gestation undergoing prenatal ultrasound at Dongguan Maternal and Child Health Hospital between September 2022 and May 2024. The case group comprised fetuses diagnosed with CTD, while controls with normal cardiac structures were collected at a 1∶2 ratio. Both groups were divided into modeling training and validation sets at a 3∶1 ratio. One optimal standard image each from the four-chamber view, left ventricular outflow tract view, right ventricular outflow tract view, and three vessels and trachea view was included per fetus. A deep learning-based multi-view fusion recognition model was developed to differentiate normal conotruncal anatomy from CTD. Model performance was validated against post-abortion pathology or postnatal echocardiography results. SAS software was used for statistical analysis to calculate the sensitivity and specificity of three fusion models (based on positivity in any two, three, or four views, and were designated as Fusion Model 1, Fusion Model 2, and Fusion Model 3, respectively), with the optimal model determined by the maximum Youden index. Senior, intermediate, and junior prenatal sonologists independently diagnosed cases in the validation set under blinding conditions. Their diagnostic results were compared with those of the optimal model. Paired Chi-square test (Cochran's Q test) was employed to compare the differences between the diagnostic accuracy rates of sonologists at different experience levels and the sensitivity of the optimal model, thereby analyzing the auxiliary diagnostic value of the multi-view fusion recognition model. Results:The study included 88 CTD cases, excluding six cases (non-CTD diagnosed by post-abortion pathology or postnatal echocardiography or poor image quality), divided into 60 training and 22 validation cases (12 tetralogy of Fallot, four double outlet right ventricle, three transposition of great arteries, three persistent truncus arteriosus). The control group included 176 cases, excluding 15 cases (other cardiac abnormalities confirmed postnatally or poor image quality after re-evaluation), divided into 120 training and 41 validation cases. The sensitivities of Fusion Model 1, Fusion Model 2, and Fusion Mudel 3 were 0.86, 0.64, and 0.27, while their specificities were 0.76, 0.95, and 1.00, respectively. Fusion Model 1 demonstrated the highest Youden index (0.62) and was selected as optimal. Its diagnostic sensitivity showed no significant difference from senior sonologists [86% vs. 91% (20/22), Bonferroni-corrected P>0.999], but was significantly higher than intermediate [55% (12/22), Bonferroni-corrected P=0.049] and junior sonologists [32% (7/22), Bonferroni-corrected P=0.003]. Conclusion:The deep learning multi-view fusion model achieved diagnostic performance comparable to senior sonologists, demonstrating potential value in assisting CTD diagnosis, training less experienced sonologists, and supporting research and education.

Objective To explore the change trend and related mechanism of resting metabolic rate induced by corticosterone in mice,and observe the intervention effects of Zhibai Dihuang Pill and Jinkui Shenqi pill.Methods Sixty-four mice were randomly divided into short-term and long-term groups,and each group was randomly divided into four groups.Mice in CORT group,ZBDH group and JKSQ group were given sterile drinking water containing corticosterone,and mice in Ctrl group were given sterile drinking water containing 1%anhydrous ethanol.Mice in ZBDH group and JKSQ group were given Chinese medicine by gavage.RMR of mice in each group was dynamically monitored during modeling and Chinese medicine intervention.The morphology of mitochondria in liver and muscle were observed by transmission electron microscope.The TR expression level in liver and muscle tissues of each group was observed by immunofluorescence,and MDA and ATP levels were detected in liver and muscle tissues of each group.levels of ACTH,TSH,INS,T3,T4,FT3,FT4,8-OHdG,FGF-21,GDF-15,L-lactic acid and pyruvic acid in serum were also detected.Results Compared with Ctrl group,the mitochondrial morphology of liver and muscle tissues in CORT group was damaged,and the expression of TR was decreased.In short-term(Day 8),RMR,ATP in liver,serum T4,ACTH and INS levels were significantly increased in the CORT group,while serum FGF-21,TSH levels and MDA in liver were significantly decreased.In long term(Day 56),RMR,serum 8-OhdG,INS,and ATP in liver and muscle were significantly decreased in the CORT group,serum FGF-21,GDF-15,T3,T4,FT3,FT4,MDA in liver and muscle were significantly increased.Compared with CORT group,in short term,RMR,serum L(+)-lactate in ZBDH group were significantly decreased,while serum 8-OHdG and the expression of TRα in muscle were significantly increased.In JKSQ group,the mitochondrial morphology of muscle tissue was improved,the expression of TRα and serum FGF-21 were significantly increased,while serum L(+)-lactic acid,FT4 and ATP in liver were significantly decreased.In long term,serum FGF-21 was significantly lower in ZBDH group,and in JKSQ group,RMR,ATP in liver tissue and TRα expression in muscle were significantly increased,while the levels of FGF-21,GDF-15,T3,FT4 in serum and MDA in muscle tissue were significantly decreased.Conclusion CORT induced RMR to increase first and then decrease with the intervention time.In the short term,Zhibai Dihuang Pill significantly decreased RMR in mice,while in the long term,Jinkui Shenqi Pill significantly increased RMR.The mechanism may be related to mitochondrial injury,thyroxine secretion and thyroxine receptor expression.

Objective To explore the current status of penile erection hardness and its influencing factors in patients with non-obstructive azoospermia.Methods From January to December 2024,450 patients with non-obstructive azoospermia were surveyed at the Reproductive Medicine Center of Hospital.A self-made general information questionnaire was used to collect their demographic data.The Erectile Hardness Scale(EHS)was employed to investigate the current status of their penile erection hardness,and a self-made questionnaire was utilized to explore the influencing factors.Results Among the 450 patients with non-obstructive azoospermia,during sexual intercourse,35.3%of the patients reported that their penile erection hardness could reach grade 4(normal state),54.5%reported that it only reached grade 3(sub-optimal state),9.3%reported that it only reached grade 2(slight penile erection),and 0.9%reported that it only reached grade 1(inability to achieve an erection).In the survey of satisfaction with sexual life quality,among the 450 patients,only 24.9%were very satisfied with their sexual life quality;57.3%were basically satisfied;9.6%considered it average;4.0%were dissatisfied;3.1%were very dissatisfied;and 1.1%had no sexual life.alcohol consumption(OR=2.393,95%CI:1.493～3.836),satisfaction with the quality of sexual life(OR=1.455,95%CI:1.118～1.894),educational attainment(OR=0.709,95%CI:0.549～0.917),and the sleep quality in the past month(OR=0.641,95%CI:0.452～0.907).Conclusions Clinical studies have shown that factors such as drinking habits,sexual life satisfaction,sleep quality,and educational attainment collectively influence the penile erection hardness in patients with non-obstructive azoospermia.Therefore,the medical team needs to customize personalized intervention plans and educational materials based on individual differences among patients.Through psychological counseling and lifestyle guidance,they can improve erectile function and the quality of sexual life,promote harmonious marital relationships,and enhance the overall life experience of the patients.
