Objective To explore the correlation of body mass index,urinary protein and tumor necrosis factor-like weak inducer of apoptosis(sTWEAK)during pregnancy with the severity of preeclampsia and pregnancy outcome.Methods A total of 63 patients with preeclampsia who were examined in Xingtai People's Hospital from April 2022 to April 2023 were enrolled in the study,33 patients with mild preeclampsia were included in the mild group and 30 patients with severe preeclampsia were included in the severe group.Physi-cal characteristics,urinary protein and sTWEAK levels between the groups were recorded,and the patients were followed up to explore the correlation with pregnancy outcome.Results The systolic and diastolic blood pressure of patients in the mild group were lower than those in the severe group,and the plasma albumin was higher than that in the severe group(P＜0.05).There was no statistically significant difference in pre preg-nancy weight and pre pregnancy body mass index between the mild and severe groups of patients(P＞0.05).The delivery weight and weight gain during pregnancy in the mild group were lower than those in the severe group(P＜0.05).The 24-hour urinary protein quantification in the mild group was lower than that in the se-vere group,and the sTWEAK expression level was higher than that in the severe group(P＜0.05).The pre pregnancy weight,pre pregnancy body mass index,delivery weight,and weight gain during pregnancy in the good pregnancy outcome group were all lower than those in the adverse pregnancy outcome group(P＜0.05).The 24-hour urinary protein quantification in the good pregnancy outcome group was lower than that in the adverse pregnancy outcome group,and the sTWEAK expression level was higher than that in the adverse pregnancy outcome group(P＜0.05).Receiver operating characteristic(ROC)curve analysis revealed that the area under the curve(AUC)of pre pregnancy body mass index,pre pregnancy weight,delivery weight,gestational weight gain,24-hour urinary protein quantification,and sTWEAK expression levels for predicting adverse pregnancy outcomes in patients were 0.906,0.690,0.919,0.664,0.908,and 0.793,respectively.The AUC for predicting adverse pregnancy outcomes in patients by combining pre pregnancy body mass index,de-livery weight,24-hour urinary protein quantification,and sTWEAK expression level was 0.932.Conclusion Body mass index,urinary protein and sTWEAK levels during pregnancy are closely associated with the severity of pre-eclampsia and pregnancy outcomes,and these indicators may help identify high-risk pregnant women early and take appropriate interventions to improve pregnancy outcomes.

Objective To explore the application effect of constructing a data sharing-based multidrug-resistant or-ganism(MDRO)information reminder system combined with multidisciplinary standardized measures on the whole-process closed-loop management of MDRO.Methods Hospitalized patients from whom MDRO were detected from January 1 to July 31,2024 were taken as the control group,those from August 1,2024,to May 31,2025 were as the intervention group.The control group adopted the traditional manual reporting mode for MDRO,while the in-tervention group adopted the combination of MDRO reminder system and multidisciplinary management mode.Differences in isolation order issuing rate for MDRO and process-and outcome-indicators for multidisciplinary spe-cialty before and after system implementation were compared.Results After implementing information reminder system combined with multidisciplinary measures,issuing rates of ≤24 hour and＜4 hour MDRO isolation orders in the intervention group were both higher than in the control group([90.20％vs 65.23％,P＜0.05],[80.64％vs 55.08％,P＜0.001],respectively).Antimicrobial use rate in the intervention group was lower than in the con-trol group(36.27％vs 43.41％),with a statistically significant difference(P＜0.05).The implementation rates of MDRO prevention and control measures,pathogen detection rates,and fluorescence labeling clearance rates in the intervention group were all higher than those in the control group,all with statistically significant differences(all P＜0.05).The detection rate of MDRO decreased compared with the control group(10.83％vs 16.49％),and the in-cidence of MDRO healthcare-associated infection in the intervention group was lower than that in the control group(0.09％vs 0.19％),both with statistically significant differences(both P＜0.001).The treatment expense in the intervention group reduced by 27 422 Yuan compared with the control group.Conclusion This study constructed an MDRO reminder system,realized full-chain monitoring system for the multidisciplinary MDRO information interac-tion platform,strengthened multidisciplinary in-depth integration,and improved the prevention and control effect for MDRO.

Objective This study aims to investigate the epidemiological characteristics of mental disorders in a rural town of Huazhou City,Guangdong Province,and explore their association with the rural revitalization strategy,so as to provide evidence for policy formulation.Methods A combination of questionnaire surveys and in-depth interviews was used to collect in-formation on the demographic characteristics,disease status,economic conditions,and policy awareness of registered mental dis-order patients in the town.Semi-structured interviews were also conducted with local doctors and village committee members.Da-ta were analyzed using descriptive statistics and logistic regression models to assess the impact of awareness of rural revitalization policies on patients'income.Results The average age of the study subjects was 47.71 years,with an average disease duration of 18.38 years.A total of 86.36％of patients had a family history of mental disorders.After onset,42.11％of patients had an annual income≥￥ 10 000,which was an increase compared to pre-illness levels,but 60.75％had completely lost their ability to work.Awareness of rural revitalization policies was low(only 18.29％were fully aware),but policy awareness was significant-ly associated with increased patient income(OR=18.03,P＜0.001).Additionally,medical expenditures were significantly higher among female patients than male patients(P＜0.001).Conclusion In a town in Huazhou City,Guangdong Province,60.75％of mental disorder patients have completely lost their ability to work,while 42.11％have an annual income exceeding ￥ 10,000.Income is positively correlated with policy awareness(OR=18.03).It is recommended to strengthen policy promo-tion,optimize the allocation of medical resources,and develop specialized assistance programs to promote the coordinated devel-opment of mental health and rural revitalization.

Objective: The CT/MRI Liver Imaging Reporting and Data System (LI-RADS) demonstrates high specificity with relatively limited sensitivity for diagnosing hepatocellular carcinoma (HCC) in high-risk patients. This study aimed to explore the possibility of improving sensitivity by combining CT/MRI LI-RADS v2018 with second-line contrast-enhanced ultrasound (CEUS) LI-RADS v2017 using sulfur hexafluoride (SHF) or perfluorobutane (PFB). Materials and Methods: This retrospective analysis of prospectively collected multicenter data included high-risk patients with treatment-naive hepatic observations. The reference standard was pathological confirmation or a composite reference standard (only for benign lesions). Each participant underwent concurrent CT/MRI, SHF-enhanced US, and PFB-enhanced US examinations. The diagnostic performances for HCC of CT/MRI LI-RADS alone and three combination strategies (combining CT/ MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or a modified algorithm incorporating the Kupffer-phase findings for PFB [modified PFB]) were evaluated. For the three combination strategies, apart from the CT/MRI LR-5 criteria, HCC was diagnosed if CT/MRI LR-3 or LR-4 observations met the LR-5 criteria using LI-RADS SHF, LI-RADS PFB, or modified PFB. Results: In total, 281 participants (237 males; mean age, 55 ± 11 years) with 306 observations (227 HCCs, 40 non-HCC malignancies, and 39 benign lesions) were included. Using LI-RADS SHF, LI-RADS PFB, and modified PFB, 20, 23, and 31 CT/MRI LR-3/4 observations, respectively, were reclassified as LR-5, and all were pathologically confirmed as HCCs. Compared to CT/MRI LI-RADS alone (74%, 95% confidence interval [CI]: 68%–79%), the three combination strategies combining CT/MRI LI-RADS with either LI-RADS SHF, LI-RADS PFB, or modified PFB increased sensitivity (83% [95% CI: 77%–87%], 84% [95% CI: 79%–89%], 88% [95% CI: 83%–92%], respectively; all P < 0.001), while maintaining the specificity at 92% (95% CI: 84%–97%). Conclusion The combination of CT/MRI LI-RADS with second-line CEUS using SHF or PFB improved the sensitivity of HCC diagnosis without compromising specificity.

Medical technology proficiency is a key indicator of a municipal-level hospital′s core competitiveness. To continuously enhance its medical capabilities, a tertiary prefecture-level hospital in Zhejiang province launched the " 100 high-tech projects" in 2010, designating it as a priority technical development program. The hospital established a hospital-level knowledge management team in 2020 to build a knowledge management system for high-tech projects. This system fostered a virtuous cycle of synergistic advancement in medical technology innovation, knowledge management, and talent development by extracting both explicit and tacit knowledge from the hospital′s high-tech projects, absorbing tacit knowledge from benchmark hospitals′ relevant technologies, and establishing a knowledge-sharing platform. From January 2021 to October 2024, the hospital secured approval for 9 national and provincial-level clinical key specialties, established 7 municipal key technological innovation teams, and enrolled 46 provincial/municipal-level talents. A the same time, talent attrition remained low. The implementation of the knowledge management system to empower high-tech development had achieved phased results. This practice could provide references for other hospitals to enhance their medical technology capabilities.

OBJECTIVE T o explore the prevention and control measures for the hospital-acquired pulmonary mu-cormycosis caused by Cunninghamella bertholletiae.METHODS One case of patient with pulmonary mucormyco-sis caused by Cunninghamella bertholletiae who was treated in pediatric intensive care unit(PICU)of a three-A general hospital was enrolled in the study,the process of clinical diagnosis and treatment was summarized.A ret-rospective survey regarding four aspects including people,machine,materials and environment was conducted.The related factors leading to the hospital-acquired infections in the patient were analyzed.RESULTS The child was diagnosed with severe aplastic anemia and underwent hematopoietic stem cell transplantation,the child was treated with various invasive procedures during the treatment period and was infected with pulmona-ry mucormycosis caused by the rare Cunninghamella bertholletiae.The occurrence of the pulmonary mucormyco-sis was associated with the poor management of medical textile,insufficient environmental cleaning and disinfec-tion and nonstandard invasive procedures.CONCLUSIONS The Cunninghamella bertholletiae infection is less com-mon,but the risk of death is high.It is necessary for the medical institutions to complete the prevention and con-trol measures and intensify the health care workers'capabilities in identification of the pathogenic fungus so as to reduce the incidence of pulmonary mucormycosis caused by the pathogen.

AIM:This study aims to investigate the effects of Feixin decoction(FXD)on pyroptosis of pulmo-nary artery smooth muscle cells(PASMCs)by modulating nuclear factor κB(NF-κB)/nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)pathway,and to explore how FXD attenuates hypoxic pulmonary hypertension(HPH)in mice.METHODS:A mouse model of HPH was established using the Sugen 5416 combined hypoxia(SuHx)method.Sixty C57BL/6 mice were randomly divided into 6 groups:control group,SuHx group,sildenafil group,and low-,medium-and high-dose FXD groups,with 10 mice in each group.Five weeks after treatment,echocardiographic pa-rameters,including pulmonary artery acceleration time(PAT),pulmonary artery ejection time(PET),right ventricular anterior wall thickness at diastole(RVAWd)and tricuspid annular plane systolic excursion(TAPSE),were measured.Right ventricular systolic pressure(RVSP)was assessed via right heart catheterization.Right ventricular hypertrophy in-dex(RVHI)was determined by weighing the hearts.Histological examination using HE staining was conducted to observe pathological changes in small pulmonary arteries and the right ventricle,while Masson staining was used to assess fibrosis in the right ventricular wall.Immunofluorescence staining was used to detect co-localized expression of α-smooth muscle actin(α-SMA)with NLRP3,N-terminal fragment of gasdermin D(N-GSDMD)and caspase-1 in the pulmonary arteries.Western blot analysis was conducted to measure the protein levels of NF-κB,p-NF-κB,NLRP3,apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC),N-GSDMD,interleukin(IL)-1β,IL-18 and cleaved caspase-1 in lung tissues.Transmission electron microscopy was employed to observe the ultrastructure of PASMCs.RE-SULTS:Compared with control group,the mice in SuHx group exhibited elevated RVSP and RVHI(P＜0.01),de-creased right heart function(P＜0.01),increased right ventricular wall fibrosis,and pulmonary vascular remodeling(P＜0.01).There was also increased co-localized expression of α-SMA with NLRP3,N-GSDMD and caspase-1 in small pul-monary arteries(P＜0.01),as well as elevated levels of p-NF-κB,NLRP3,ASC,N-GSDMD,IL-1β,IL-18 and cleaved caspase-1 in lung tissues(P＜0.01),indicating induced pyroptosis of PASMCs.Compared with SuHx group,FXD treat-ment significantly reduced RVSP and RVHI,improved right ventricular function,and attenuated right ventricular wall fi-brosis and pulmonary vascular remodeling(P＜0.05 or P＜0.01).Treatment with FXD also decreased the co-localized ex-pression of α-SMA with NLRP3,N-GSDMD and caspase-1 in small pulmonary arteries(P＜0.05 or P＜0.01),and down-regulated the protein expression of p-NF-κB,NLRP3,ASC,N-GSDMD,IL-1β,IL-18 and cleaved caspase-1 in lung tis-sues(P＜0.05 or P＜0.01),thereby attenuating the pyroptosis of PASMCs.CONCLUSION:FXD attenuates pulmonary vascular remodeling and right ventricular dysfunction in a mouse model of HPH.This effect may be attributed to its inhibi-tion of NF-κB/NLRP3 pathway,which subsequently reduces the pyroptosis of PASMCs.

ObjectiveTo investigate the expression of serum Aldo-keto reductase family 1 member B10 （AKR1B10） in patients with hepatocellular carcinoma （HCC） in northern China， and to provide a new and valuable biomarker for the clinical diagnosis of HCC. MethodsThis study was conducted among 102 patients with HCC， 119 patients with benign liver disease， and 132 patients with other malignant tumors who attended The Affiliated Hospital of Chengde Medical University and 148 healthy individuals who underwent physical examination from May 2020 to May 2024. ELISA and chemiluminescence were used to measure the serum levels of AKR1B10 and alpha-fetoprotein （AFP）. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the Kruskal-Wallis H test was used for comparison between three groups and further comparison between two groups； the chi-square test was used for comparison of categorical data between groups. The area under the ROC curve （AUC） was used to assess diagnostic efficiency. ResultsThe expression level of AKR1B10 was 3 053.79 （1 475.67‍ ‍—‍ ‍4 605.86） pg/mL in the HCC group， 1 324.42 （659.68‍ ‍—‍ ‍2 023.88） pg/mL in the benign liver disease group， 660.68 （377.56‍ ‍—‍ ‍2 087.77） pg/mL in the other malignant tumor group， and 318.30 （82.73‍ ‍—‍ ‍478.82） pg/mL in the healthy group， with a significant difference between the four groups （H=240.86， P<0.001）， and further comparison between two groups showed that the HCC group had a significantly higher level than the other three groups （all P<0.001）. The ROC curve analysis of the HCC group and the other three groups showed that serum AKR1B10 had an optimal cut-off value of 1 584.97 pg/mL in the diagnosis of HCC， with an AUC of 0.86 （95% confidence interval ［CI］： 0.82‍ ‍—‍ ‍0.90）， a sensitivity of 74.3%， and a specificity of 85.2%. Compared with each indicator alone， a combination of AKR1B10 and AFP could improve the sensitivity （81.8%） and specificity （91.4%） of HCC diagnosis. AKR1B10 had an AUC of 0.84 （95%CI： 0.78‍ ‍—‍ ‍0.90） in the diagnosis of patients with early- or middle-stage HCC， with a sensitivity of 76.2% and a specificity of 81.2%. AKR1B10 had an AUC of 0.85 （95%CI： 0.77‍ ‍—‍ ‍0.92） in the diagnosis of patients with AFP-negative HCC， with a sensitivity of 81.6% and a specificity of 79.9%. ConclusionAKR1B10 is a promising serological marker for the diagnosis of HCC， and a combination of AKR1B10 and AFP can improve the detection rate of HCC patients in northern China， especially those with early- or middle-stage HCC and AFP-negative HCC.
