Both hyperlipidemic acute pancreatitis and fatty liver disease are associated with lipid metabolism disorders and are commonly comorbid with each other in clinical practice. The pathogenesis of such comorbidity involves the interaction between multiple factors such as hypertriglyceridemia， metabolic syndrome， obesity， and insulin resistance， and these factors may form a vicious cycle and jointly promote disease progression. In clinical practice， hyperlipidemic acute pancreatitis is characterized by severe disease conditions， a high incidence rate of complications， a high mortality rate， and a tendency for recurrence， and it can easily lead to multi-organ damage and even multiple organ failure without timely treatment， posing a serious threat to the life of patients. Starting from the various signaling pathways associated with hyperlipidemic acute pancreatitis comorbid with fatty liver disease， this article discusses the potential molecular mechanisms of synergistic pathogenesis between hyperlipidemic acute pancreatitis and fatty liver disease， so as to provide a reference for the early prevention and treatment of such comorbidity.

Objective: To explore the effects of intergenerational parent-child separation on internalizing and externalizing behavioral problems among rural preschoolers aged 3-6 years, so as to provide empirical evidence for formulating targeted intervention strategies and blocking the intergenerational transmission of parent-child separation. Methods: From March to June, 2024, ten kindergartens were selected from rural areas of Nanling County, Wuhu City, Anhui Province, and 2 279 preschool children aged 3- 6 years, along with their fathers, mothers and primary caregivers, were recruited for survey by cluster convenient sampling method. Children s fathers and mothers reported their own childhood parent-child separation information separately. Information on the children s history of psychological and behavioral problems was reported by the primary caregivers. Information of internalizing and externalizing behavioral problems in preschool children was reported with Strengths and Difficulties Questionnaire (SDQ).The Chi square test was used to compare the differences in the detection rates of psychological and behavioral problems among children with different intergenerational continuity of parent-child separation. Binary Logistic regression model was applied to analyze the association between intergenerational continuity of parent-child separation and internalizing and externalizing behavioral problems in preschool children. Results: The detection rate of internalizing behavioral problems was 27.5% and externalizing behavioral problems was 19.1% among rural preschool children. There were significant differences in internalization behavior, externalization behavior, hyperactivity impulse and peer communication problems among preschool children in different types of parent-child separation groups( χ 2=14.29, 8.80, 17.26, 13.84, all P <0.05). Binary Logistic regression analysis showed that after adjusting for covariates such as children s gender, birth weight, and delivery mode, compared with children without separation, intergenerational continuity of parent-child separation group( OR =1.95), only child separation( OR =1.74) were associated with significant higher risk of conduct problems(both P ＜0.05). Parent-child separation intergenerational continuation groups( OR =1.68), only child separation( OR = 1.47) were associated with significant higher risk of peer problems(both P ＜0.05). Both types of parent-child separation experiences significantly increased the risk of children s prosocial behavior problems，among them, the intergenerational continuation group was 1.99 times that of the control group ( OR =1.99), and the childhood only separation group was 2.09 times that of the control group ( OR =2.09)(both P ＜0.05). Compared with children whose parents and children had no experience of parent-child separation, children in the intergenerational continuation group of parent-child separation had increased risks of both internalizing and externalizing behavior problems ( OR =1.53, 1.65, both P <0.05). Conclusion All types of parent-child separation are associated with internalizing and externalizing behavioral problems among rural children aged 3 to 6 years.

Background Against the backdrop of global warming, extreme high-temperature weather events are becoming more frequent and pose a substantial threat to human health. Urumqi is located in a typical arid climate zone, but the health effects of heatwaves in this region remain insufficiently understood. Objective To evaluate the association between heatwave events and non-accidental mortality among residents in Urumqi, quantify the attributable mortality burden, identify vulnerable populations, and provide scientific evidence to support the development of targeted regional intervention strategies. Methods Data on non-accidental mortality, meteorological variables, and air pollutants in Urumqi from 2018 to 2024 were collected. A heatwave was defined as three or more consecutive days with daily mean temperature exceeding the 90th percentile of the study period. Under a time-stratified case-crossover design, a generalized additive model incorporating a cross-basis function within the distributed lag nonlinear model framework was applied to simultaneously assess the single-day (lag0-lag7) and cumulative (lag01-lag07) lag effects and exposure-response relationship of heatwave exposure with non-accidental mortality. Heatwave-attributable excess deaths was further estimated. Results The exposure-response relationship between daily mean temperature exposure and non-accidental mortality in Urumqi exhibited a J-shaped curve. Using 25 ℃ as the reference temperature, mortality risk increased when temperature exceeded 27.4 ℃. The cumulative relative mortality risk over lag07 following heatwave exposure was 1.100 (95%CI: 1.059, 1.142), with the highest effect observed at lag06 (RR=1.151, 95%CI: 1.095, 1.209). Subgroup analyses showed that females (lag06, RR=1.169, 95%CI: 1.082, 1.262) and residents aged ≥65 years (lag06, RR=1.156, 95%CI: 1.092, 1.224) had higher mortality risks than males (lag06, RR=1.140, 95%CI: 1.069, 1.216) and residents aged <65 years group (lag06, RR=1.141, 95%CI: 1.035, 1.257), respectively. The increased risk appeared earlier among females, beginning at lag02, compared with lag03 among males. Heatwave-attributable excess deaths showed an overall upward trend, peaking at 248 (95%CI: 152, 341) deaths in 2023 and 229 (95%CI: 141, 314) deaths in 2024. Conclusion Heatwave events are significantly associated with an increased risk of non-accidental mortality among residents in Urumqi, primarily through cumulative lag effects under consecutive days of exposure. Females and residents aged ≥65 years are identified as vulnerable populations. The estimated excess deaths attributable to heatwaves show an overall upward trend.

Objective:To explore the influence of artificial intelligence(AI)-assisted compressive sensing(ACS)technique with different acceleration factors on the image quality and scan time of three dimensional time-of-flight magnetic resonance angiography(3D-TOF-MRA)for brain.Methods:Thirty participants who underwent brain magnetic resonance imaging(MRI)at Tongzhou Branch of Beijing Friendship Hospital were recruited.All subjects underwent imaging scans about four different parameters:a non-accelerated technique(control group),ACS technique integrated with acceleration factor of 4.03(ACS4 group),ACS technique integrated with acceleration factor of 5.02(ACS5 group),and ACS technique integrated with acceleration factor of 6.06(ACS6 group).The image clarity,ranking of imaging capabilities of distal branch blood vessels and the ratio of pseudo-stenosis were qualitatively analyzed.The signal-to-noise ratio(SNR),contrast-to-noise ratio(CNR),edge sharpness,and scan time were quantitatively analyzed.Results:There was not difference in vessel clarity among three ACS groups at the proximal and middle intracranial segments.For distal segments of blood vessel,the ACS4 group[3.0(3.0,3.0)]and ACS5 group[3.0(3.0,3.0)]were better than ACS6[2.5(2.0,3.0)](q=29.800,27.500,P<0.05).The imaging capabilities of distal-branch vessel of ACS4 group and ACS5 group were better than ACS6 group.There was no stenosis in the proximal and middle segments of the images of the three ACS group,and there were no stenosis in the images of distal vessels of ACS4 group and ACS5 group.A total of 5 cases were pseudo-stenosis in the distal vessels of ACS6 group.Compared with the control group,the incidence of pseudo-stenosis in the distal vessels of ACS6 group was 16.7%.The SNR and CNR values of quantitative analysis for proximal vessels in ACS6 group were higher than them in ACS4 group(q=27.800,26.200,P<0.05),and there was not significant difference in them among ACS4 group,ACS6 group and ACS5 group(P>0.05).The differences of SNR and CNR values in the middle and distal segments of blood vessels among different groups were not significant(P>0.05).There was not significant difference in the edge sharpness of blood vessels among ACS4 group,ACS5 group,and ACS6 group(P>0.05),while all of them were higher than those of control group,and the differences were significant(q=48.150,53.367,44.883,P<0.001).Compared with control group,the scan-time of ACS4 group was reduced by 55.19%,and that of ACS5 group was reduced by 64.07%,and that of ACS6 group was reduced by 70%.Conclusion:ACS technique can accelerate the imaging speed of brain 3D-TOF-MRA and ensure image quality.It is clinically recommended to set the ACS acceleration factor as 5.02 to undergo brain 3D-TOF-MRA scans.

Objective:This study identifies independent predictive indicators to distinguish autoimmune gastritis from Helicobacter pylori ( H. pylori)-induced atrophic gastritis and validates their diagnostic performance to compare laboratory indicators of autoimmune gastritis and H. pylori-induced atrophic gastritis. Methods:A retrospective comparison of laboratory examination indicators was conducted for chronic atrophic gastritis patients with involvement of the gastric fundus and corpus, who were followed up at the Department of Gastroenterology, Xijing Hospital, from January 2014 to September 2024. Receiver operating characteristic (ROC) curves were utilized to determine the optimal cutoff points and corresponding diagnostic thresholds. In addition, multivariate logistic regression analysis was conducted to identify independent predictive indicators for autoimmune gastritis, with further assessment in a validation cohort.Results:A total of 139 patients with autoimmune gastritis and 209 patients with H. pylori-induced atrophic gastritis were included. Pepsinogen (PG) Ⅰ levels and the PG Ⅰ/PG Ⅱ ratio in patients with autoimmune gastritis were significantly lower than in those with H. pylori-induced atrophic gastritis [11.0 (4.8, 22.5) vs. 41.8 (32.2, 59.9) μg/L, U=722.00, P<0.001; 1.24 (0.75, 3.54) vs. 5.76 (4.31, 7.12), U=817.00, P<0.001], while gastrin levels were significantly higher [375 (84, 738) vs. 49 (35, 81) ng/L, U=378.00, P<0.001]. PG Ⅰ was identified as an independent predictive variable, with an area under the ROC curve of 0.847 (95% CI 0.791-0.904), sensitivity of 77.6%, specificity of 91.8%, positive predictive value of 80.5%, and negative predictive value of 90.5%. Conclusions:Significant differences in laboratory indicators were observed between autoimmune gastritis and H. pylori-induced atrophic gastritis in chronic atrophic gastritis involving gastric fundus and corpus. Besides, PG Ⅰ demonstrated good diagnostic performance in identifying autoimmune gastritis and can effectively differentiate between different types of atrophic gastritis.

[Objective]To investigate the composition of Songya Yijing,the comprehensive medical book during the Ming Dynasty,in order to identify its literature value.[Methods]Systematically comparing the font styles,page frames,center margins and other physical characteristics of the major extant versions(Ming edition,CHENG Jia edition,etc.),and tracing their lineage.In-depth analysis of the similarities and differences in the syndrome differentiation systems across various sections of the book,examining contradictions in the author's personal information,and systematically tracing the literary sources of the formulas in Volume Ⅱ.Investigating local gazetteers,clan genealogies and other historical materials to extract records concerning CHENG Jie's achievements in pulse diagnosis and explore their connection to the core content of Songya Yijing.[Results]In terms of versions,the Collection on Febrile Caused by Cold in the Ming Dynasty edition differed in font and layout from other sections,indicating it was added by later generations;the CHENG Jia's edition was based on the Ming edition,with the name CHENG Jingtong forged in later times.Regarding content,the Collection on Febrile Caused by Cold adopted a unique syndrome differentiation system,unrelated to CHENG Jie;Volume Ⅱ mainly copied from orthodox Medical Records and incorporated later works like Fushou Jingfang,with contradictions in personal details;sections such as"Six Categories in Diseases""Map of Six Categories of Syndromes""Treatments and Medical Treatment Prescription"were pulse-based,aligning with CHENG Jie's expertise in pulse diagnosis and possibly originating from his original work.[Conclusion]Songya Yijing is a pseudepigraphical compilation falsely attributed to CHENG Jie,with only partial pulse-related content potentially retaining his original ideas and limited originality overall.However,its systematic collation of pulse syndromes holds documentary value.Future research could focus on clarifying key issues in the transmission of Xin'an medical literature.

Objective To evaluate the clinical efficacy of Shexiang Tongxin dropping pills combined with"Quadruple therapy"in elderly patients with heart failure with preserved ejection fraction(HFpEF).Methods A total of 193 elderly HFpEF patients admitted to Affiliated Hospital of Yangzhou University from January to June 2022 were selected as study objects,and were divided into observation group(97 cases)and control group(96 cases)according to random number table method.The control group was treated with sacubitril valsartan sodium tablets+dapagliflozin tablets+metoprolol tartrate tablets+spironolactone tablets,and the observation group was treated with Shexiang Tongxin dropping pills on the basis of control group treatment,and both groups were treated for 6 months.The changes of cardiac function indexes,serum myocardial injury markers,endothelial function and inflammation indexes before and after treatment were compared between two groups.The average length of hospitalization,readmission rate within 30 days and the effective rate of treatment were analyzed.After 6 months of follow-up,the 6-minute walk test,6-month readmission rate and the incidence of major adverse cardiovascular event(MACE)were compared between two groups.Results After 30 days of treatment,the total effective rate of observation group was significantly higher than that of control group(93.8％vs.90.6％,x2=3.982,P=0.031).After 30 days of treatment,left ventricular end diastolic diameter,left ventricular end systolic diameter,N-terminal pro-brain natriuretic peptide,cardiac troponin I,nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 in observation group were significantly lower than those in control group,left ventricular ejection fraction,early peak mitral valve diastolic blood flow velocity(E)/advanced peak mitral valve diastolic blood flow velocity(A)and nitric oxide were significantly higher than those in control group,and 6 min walking distance was significantly longer than that in control group(P＜0.05).After 6 months of follow-up,the average length of hospital stay in observation group was significantly lower than that in control group,and the readmission rate within 30 days was significantly lower than that in control group(P＜0.05).There was no significant difference in the 6-month readmission rate and the incidence of MACE between two groups(P＞0.05).Conclusion Shexiang Tongxin dropping pills can inhibit cardiac inflammation.Combined with the"Quadruple therapy",the clinical effect of HFpEF in elderly patients is better than that of western medicine alone,and it is worthy of clinical promotion and application.

Objective:To develop and validate a clinical warning model for severe pediatric community-acquired pneumonia (CAP) using electronic health records.Methods:A retrospective cohort study was conducted, analyzing clinical data of 15 750 children hospitalized for CAP at Wuhan Children′s Hospital between January 1, 2019, and December 31, 2023. Patient data were randomly split into training and testing sets at a 7∶3 ratio. Six supervised machine learning models were constructed in the training set, optimized using five-fold cross-validation, and evaluated in the testing set. Model performance was assessed using ROC-AUC, sensitivity, specificity, positive predictive value, negative predictive value, calibration curves, and clinical decision curve analysis at optimal thresholds. The best-performing model was selected, and SHapley Additive exPlanations (SHAP) were used to interpret feature importance. A program interface was developed based on the model results, enabling integration into clinical decision support systems for automated early warning.Results:A total of 15 750 participants, ranging in age from 28 days to 18 years, were included in the study. The median age was 2 years [interquartile range (IQR): 0-4 years], with 9 555 males (60.67%) and 6 195 females (39.33%). Among them, 2 211 (14.04%) developed severe pneumonia. In the prediction models, XGB outperformed other models with an ROC-AUC of 0.884 (95% CI: 0.870-0.898), sensitivity (0.803, 95% CI: 0.772-0.832), specificity (0.828, 95% CI: 0.816-0.839). Calibration analysis showed strong agreement between predicted and observed risks (Brier score: 0.081, 95% CI: 0.075-0.086). The analysis based on the SHAP method revealed that respiratory rate, heart rate, T-lymphocyte subsets, and red blood cell volume distribution width-SD are predictive factors for severe progression of community-acquired pneumonia (CAP) in children. Conclusion:An interpretable machine learning model was developed for the early detection and personalized treatment planning of severe CAP in children, providing valuable support to clinicians.

Objective:To explore the impact mechanism of strategic human resource management (SHRM) capabilities in hospital clinical departments on departmental organizational performance, providing references for improving the overall performance of hospitals.Methods:The research subjects were 46 clinical departments of a tertiary public hospital in Beijing. Using a stratified sampling method, at least one middle-level manager was selected from each department, and 30% of the medical staff were randomly sampled from each professional title level within the department. A self-made questionnaire was used to investigate the SHRM capabilities of each department from September to December 2023. The organizational performance of clinical departments was assessed using the departmental performance evaluation system established by the hospital. First, the performance target values for each department in 2023 were set based on the historical data from 2020 to 2022. Then, the actual performance evaluation data of 2023 were compared with the target values to calculate the achievement rate or deviation. Finally, the comprehensive performance scores of each department were calculated by weighting. The performance scores of the departments in 2023 were used as the outcome variable, while SHRM capabilities, department size, number of beds, and whether the department was a key department were used as antecedent condition variables. Fuzzy-set qualitative comparative analysis (fsQCA) was employed to explore the combinations of antecedent conditions that lead to high and low organizational performance in clinical departments.Results:A total of 1 391 valid questionnaires were collected. The weighted average score of SHRM capabilities in clinical departments was (4.23±0.27) points, and the total score of organizational performance evaluation in 2023 was 70.75 (52.50, 79.47) points. The consistency of each antecedent condition variable did not reach the critical value of 0.90, indicating that none of them were sufficient to be a necessary condition for high or low organizational performance in the departments. Two pathways to high organizational performance and two pathways to low organizational performance were identified. The solution consistency for the high organizational performance pathway was 0.83, with a coverage of 0.35, and both core conditions, acquisition capability and maintenance capability, were present. The solution consistency for the low organizational performance pathway was 0.85, with a coverage of 0.08, and the core conditions, development capability, was absent.Conclusions:Different combinations of antecedent condition variables, including the strategic human resource management capability of clinical departments, had varying impacts on the organizational performance of clinical departments. The possession of human resource acquisition, maintenance, and development capabilities by clinical departments was an essential condition for achieving high organizational performance. It is recommended to strengthen the construction of these three capabilities and emphasize the coordinated development of human resource management capabilities to enhance the organizational performance of clinical departments.
