Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Objective To evaluate the effectiveness of active screening in improving the detection rate of carbape-nem-resistant Enterobacterales(CRE)in the intensive care units(ICUs).Methods From July 2023 to June 2024,active screening of rectal swab CRE was conducted on ICU patients in 10 hospitals.ICU patients who underwent ac-tive screening from July 2023 to June 2024 were selected as the study group,while those who did not undergo active screening from July 2022 to June 2023 were selected as the control group.Difference in CRE detection rates between the two groups of patients was compared.Results A total of 7 803 ICU patients were included in the study group,744 CRE strains were detected,with a detection rate of 9.53％,out of which 304 CRE strains were detected through routine detection(detection rate 3.90％),3 707 patients underwent active screen,440 CRE strains were detected(detection rate 11.87％).7 561 ICU patients were included in the control group,out of which 250 CRE strains were detected through routine detection,with a detection rate of 3.31％.There was a statistically significant difference in the overall detection rate of CRE between two groups of patients(x2=246.18,P＜0.001).In the study group,CRE detection rate of active screening(11.87％)was higher than that of routine detection(3.90％),with statistically significant difference(x2=264.26,P＜0.001).A total of 17 CRE strains were detected from the study group.The proportions of Klebsiella pneumoniae(80.92％vs 73.41％)and Serratia marcescens(2.30％vs0.23％)in the routine detection group were both higher than in the active screening group,while the proportion of Escherichia coli in the routine detection group was lower(8.22％vs 19.55％),all with statistically significant differences(all P＜0.05).Conclusion The prevalence of CRE in ICUs is relatively high,with a wide range of bac-terial species.Active screening can improve the detection rate of CRE.

Both cold stress and ischemia-reperfusion injury significantly contribute to poor prognosis after liver transplantation(LT).However,limited animal models incorporating both stimuli hinder the advance-ment of transplant-related research.Here,a simplified and reproducible isolated perfused liver model is established to simulate the stresses experienced by livers maximally during transplantation.We provide a detailed protocol for a straightforward technique that requires 20-30 min for harvesting,24-48 h for static cold storage(SCS),and 2 h for normothermic machine perfusion(NMP)to induce LT-like stresses in the liver.Hepatic injury from SCS and NMP(LT-like stresses)is evaluated using three types of parameters.The pH values and hepatic enzyme levels of cold preservation solutions and perfusate serve as dynamic indicators of hepatic injury.Bile production and portal venous resistance directly reflect liver function,whereas pathological analysis visually illustrates the location and extent of injury.This animal model eliminates the influence of hemodynamic and immune factors,yielding highly reproducible results,and is strongly recommended as a standardized animal model for inducing LT-like stresses.

Objective:To explore the clinical application value of MRI ultra-short echo time sequence (MRI-UTE) in the diagnosis of pulmonary nodules.Methods:This study was a cross-sectional study. A total of 101 consecutive patients were recruited prospectively from January to August 2024 at Huazhong Fuwai Hospital of Zhengzhou University. All of the included patients were diagnosed with pulmonary nodules by chest CT examination and intended for treatment. All patients underwent low-dose CT examination and MRI-UTE examination. The number, classification, and lung imaging reporting and data system (lung-RADS) grading of the pulmonary nodules were analyzed. Nodules classification was determined as solid nodules or sub-solid nodules, and sub-solid nodules included part-solid nodules and pure ground-glass nodules. Taking the evaluation results of radiologists with 10 and 12 years of experience in chest imaging diagnosis as the reference standard, the Kappa test was used to analyze the agreement of CT and MRI-UTE in terms of the accurate diagnosis, classification, and lung-RADS grading of pulmonary nodules. Results:Among the 101 patients, a total of 216 pulmonary nodules were identified. MRI-UTE accurately diagnosed 180 pulmonary nodules, while 203 pulmonary nodules were detected by CT. The concordance was moderate ( Kappa=0.48, P<0.001). In terms of nodule classification, CT correctly classified 167 nodules as solid and 36 as sub-solid, whereas MRI-UTE correctly classified 153 as solid and 23 as sub-solid, with good agreement (weighted Kappa=0.73, P<0.001). For lung-RADS grading, CT correctly graded 186 nodules, with 85 graded as category 2, 46 as category 3, 33 as category 4A, 12 as category 4B, and 10 as category 4X; MRI-UTE correctly graded 155 nodules, with 74 graded as category 2, 30 as category 3, 30 as category 4A, 12 as category 4B, and 9 as category 4X. The agreement between the two modalities in determining lung-RADS grade was also good (weighted Kappa=0.74, P<0.001). Conclusion:MRI-UTE demonstrates good agreement with CT in the accurate diagnosis, classification, and lung-RADS grading of pulmonary nodules, indicating certain clinical application value.

Objective: To understand the growth and development levels of four physical measurements in children aged 3-6 years in China, so as to provide a reference for child nutrition improvement and health promotion. Methods: A stratified random sampling method was used to collect physical measurement data from 120 kindergartens 25 842 children aged 3-6 years across 24 provinces and cities in seven natural geographical regions of North China, Northeast China, East China, Central China, South China, Southwest China and Northwest China from 2020 to 2023. The development levels of head circumference, chest circumference, waist circumference, and hip circumference were evaluated using a grading method. The analysis of gender and age differences was conducted using Mann-Whitney U- test and Kruskal-Wallis test, and the comparison of abnormal detection rates for different genders was conducted using Chi square test. Results: The distribution range of children aged 3-6 was 51.74(50.08, 53.33) cm in terms of head circumference, 55.73(52.09, 59.04) cm in terms of chest circumference, 53.04(48.92, 56.40) cm in terms of waist circumference, and 59.36(56.30, 62.32) cm in terms of hip circumference. The detection rate of abnormal head circumference in boys and girls aged 3-6 years old was relatively high (19.71%-42.02%), and the detection rate of abnormal physical circumference development levels in boys was higher than that in girls of all ages ( χ 2=5.63-83.35, P <0.05). The detection rate of abnormal hip circumference (4.89%-6.53%) and chest circumference (4.51%-6.38%) in boys and girls aged 3-6 was relatively low, and there was no statistically significant difference in the abnormal rate between different ages and genders ( χ 2=0.00-1.61, 0.00-3.71, P >0.05). The detection rate of abnormal waist circumference in boys and girls aged 3-6 was relatively high (13.70%-42.45%), and the detection rate of abnormal waist circumference in girls was higher than that in boys aged 4-6 groups ( χ 2=10.49-58.18, P < 0.05). Conclusions The overall physical development of children aged 3-6 years in China is improving, but the abnormal detection rates for head circumference and waist circumference are relatively high. Child healthcare should focus on preventing and treating abdominal obesity, with differentiated health intervention strategies based on different age groups and genders.

Objective:To explore the correlation between serum uric acid/high-density lipoprotein cholesterol ratio (UHR) and the risk of hypertension in elderly physical examination populations.Methods:This study was a cross-sectional study. A total of 1 028 patients aged≥60 years who underwent physical examinations at the Health Management Center of Fuwai Central China Cardiovascular Hospital from September 2023 to February 2024 were included in this study. The general demographic data, past medical history, physical examination and laboratory examination indicators of the physical examiners were collected, and according to whether they had hypertension or not, they were divided into hypertension group (390 cases) and non-hypertension group (638 cases), and all UHR values were arranged from small to large, and the UHR was divided into three groups by tertiles of UHR, and the general data and blood biochemical indexes between the groups were compared. Spearman rank correlation was used to analyze the correlation between UHR level and body mass index, total cholesterol, triglyceride and other indexes in the elderly population. Logistic regression was used to explore the relationship between UHR level and hypertension in the elderly population, and the stratification analysis of the physical examination population was carried out according to diabetes, coronary heart disease and dyslipidemia, and the interaction test between groups was carried out.Results:Among the 1 028 geriatric physical examination cases, 580 (56.4%) were males and 448 (43.6%) were females, aged (66.7±5.8) years. UHR levels were higher in the hypertensive group compared to the non-hypertensive group [248.88 (191.19, 322.25) vs 213.52 (165.94, 275.29); Z=-5.445, P<0.05]. With the increase of UHR level, the detection rate of hypertension in the elderly population increased (accounted for 27.8%, 38.2% and 47.8%, respectively; χ2=29.211, P<0.05). Spearman rank correlation analysis showed that UHR was positively correlated with body mass index, triglycerides, serum uric acid, serum creatinine and fasting blood glucose ( r=0.318, 0.334, 0.774, 0.474, 0.080; all P<0.05), and negatively correlated with total cholesterol, glomerular filtration rate and low-density lipoprotein cholesterol ( r=-0.239, -0.303, -0.154; all P<0.05). When the confounding factors were not adjusted (model 1), the risk of hypertension in high UHR group was 2.382 times higher than that in low UHR group and 1.607 times higher than that in medium UHR group; after adjusting for all confounding factors such as age, gender, body mass index, systolic blood pressure, diastolic blood pressure, junior high school education or below, smoking, alcohol consumption, glomerular filtration rate, etc., the risk of hypertension in the high-level UHR group was 1.732 times higher than that in the low-level UHR group (95% CI: 1.139-2.635) ( P<0.05). The elderly physical examination population was further stratified according to whether there was diabetes, dyslipidemia and coronary heart disease, and it was found that there was no interaction between UHR and diabetes, dyslipidemia and coronary heart disease on the prevalence of hypertension (all P>0.05). Conclusions:Hypertension detection rate increases with higher UHR levels. UHR is closely related to the incidence of hypertension in the elderly population.

Operation management is an important tool to promote the high-quality development of public hospitals in China.Since the founding of New China,based on China's economic and social development and medical and health system reform,the evolution of operation management of public hospitals in China can be divided into four stages,the system building stage(1949-1978),the liberalization and revitalization stage(1979-1996),the operation mechanism reform stage(1997-2020),and the new stage of high-quality development(2021 present).The development trend of public hospital operation management in future should deepen the public welfare-oriented public hospital operation management,explore the value-oriented medical operation management model based on high-quality development and the refined operation and management model of public hospitals,so as to promote the high-quality development of public hospitals in China.

Promoting the innovation of the operational assistant service model of public hospitals is an important task to realize the lean operation management of public hospital.Through literature research,four typical operational assistant service models currently implemented in public hospitals in China are summarized:the specialized opera-tional assistant service model,the part-time operational assistant service model,the'team-based'operational assistant service model,and the hybrid financial assistant service model combining full-time and part-time roles.These four models are compared and analyzed from five dimensions:management system,role positioning,per-sonnel composition,selection and training,and service mechanism.Based on this,it is proposed that a new Spe-cialized Multi-Disciplinary Team operational assistant service model should be explored and developed according to local conditions to meet the new requirements for lean operational management and high-quality development of public hospitals in the new era.

Objective To construct a competency modeling index system for operation assistants,and to provide a scientific tool for the selection,training,assessment and evaluation of operation assistants in public hospitals.Methods The job analysis method is used to analyze the job responsibilities and functional positioning of operation assistants;key elements of operation assistant competency are extracted based on the iceberg model,and the competency evaluation indexes are constructed by borrowing thematic group discussion and expert consulting method;the CRITIC weight method is used to determine the weights of each index.Results A competency evaluation index system for operations assistants in public hospitals was established with five dimensions and 19 indicators,including professional knowledge,work skills,coordination ability,behavioral motivation and personal traits.Conclusion The competency evaluation index system for operations assistants in public hospitals constructed in this study is of good scientific quality and can provide a quantitative evaluation tool for realizing job matching.

Under the new situation,the selection of operation assistants in public hospitals is a major measure to improve the level of lean operation management of hospitals,so it is very important to design a scientific and reasonable selection and training mechanism for operation assistants.Through literature research and drawing on the competency model,a tertiary grade A cardiovascular disease hospital was selected as a case study to explore the construction of a selection mechanism from four aspects:selection objects,selection conditions,selection methods and selection criteria.Five training mechanisms were formulated from five aspects:capacity improvement,clinical service,data analysis,evaluation and feedback,and organizational behavior norms,and then it was proposed that attention should be paid to the scientific,feasible,replicable and innovative nature of the selection and training mechanism,so as to build an effective public hospital operation assistant team.
