Objective:To provide theoretical support and practice model for improving the clinical medical education supervision system of university-affiliated hospitals.Methods:This study focused on the group of reserve teaching supervision experts. Through literature research, questionnaire survey, and expert interview, the Competency Evaluation Criteria for Reserve Teaching Supervision Experts was constructed, which was implemented according to the training framework of "theory, practice, summary, and feedback". The paired t-test was performed using SPSS 24.0. Results:The research team formulated the Competency Evaluation Criteria for Reserve Teaching Supervision Experts through expert interviews. Six basic competencies and three advanced competencies for reserve teaching supervision experts were identified and their weights were assigned. A supervision team was established with supervision experts (including reserve teaching supervision experts) and teaching staff at a ratio of 1∶6.9, achieving an increase in the coverage of supervised specialties. A toolkit for enhancing the supervision capabilities of reserve experts was developed, and its effectiveness was analyzed. Statistical analysis showed that the overall score gap between reserve teaching supervision experts and senior supervision experts gradually narrowed. In terms of teaching demeanor and teaching effectiveness, there were no significant differences between the two types of experts. However, in terms of teaching content scores, there was a significant difference between reserve teaching supervision experts and senior supervision experts ( P<0.05). Conclusions:The training mechanism of reserve teaching supervision experts can effectively bridge the structural defects of the traditional supervision team. However, further emphasis is needed on the standardization and professionalization of teaching content supervision.

Rodents in China encompass diverse species with wide distributions,and carry an array of pathogens,thus posing substantial risks to human health and safety.In this paper,the literatures related to rodent—carrying pathogens in China were screened and analyzed from databases such as CNKI,Wanfang Database,Google Scholar,and Pubmed.An analysis of surveil-lance data for bacterial pathogens borne by these rodents revealed the presence of 19 distinct pathogens,including Yersinia pes-tis,Bartonella,and Borrelia burgdorferi,across 30 provinces,autonomous regions,and municipalities.Notably,positive tests for 15 of these bacterial pathogens were observed in Yunnan Province,whereas Bartonella was detected in 28 provinces.The survey encompassed a total of 107 rodent species,84 of which were classified as Rodentia,representing 78.50％of the to-tal.Among these,82 species were found to be carriers of Bartonella.This comprehensive analysis and synthesis of surveillance data on rodent-borne bacterial pathogens provided not only insights into pathogen prevalence and distribution across regions,but also a valuable resource for the development of early warning systems and strategies for the prevention and control of disea-ses transmitted by rodents.

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.

Thoracic anesthesia with spontaneous respiration represents a form of precision anesthesia meticulously customized to individual patients.Considering the more stringent requirements this anesthesia approach imposes on the regulation of respiratory function,the writing group of the"Consensus of Experts on the Management of Thoracic Anesthesia with Spontaneous Respiration"has formulated elaborate guidelines regarding indications and contraindications,preoperative evaluation,anesthesia implementation,common complications,and treatment strategies.This was accomplished by referencing relevant domestic and international literature and integrating it with actual clinical requirements.The objective is to standardize the rational application of this anesthesia method.

Objective To explore the value of analysis on the incidence of healthcare-associated infection(HAI)based on disease diagnosis-related grouping(DRG),case mix index(CMI),and relative weight(RW).Methods All discharged cases,DRG and HAI status in a tertiary first-class general hospital from January 1 to December 31,2023 were analyzed retrospectively.Incidences of HAI in different departments were adjusted and compared by CMI.Incidences of HAI in different DRG groups were adjusted by RW.Results Among the 47 695 cases included in the analysis,757 were HAI cases,including 225 DRG groups.The department of critical care medicine had the highest incidence of HAI(11.98％).After CMI adjustment,departments with higher incidence of HAI were main-ly the department of respiratory and critical care medicine(3.96％),department of critical care medicine(3.04％),and department of neurology(2.85％),et al.DRG groups with the top five high incidence of HAI were AH11(tracheotomy and with ventilator support ≥96 hours or extracorporeal membrane oxygenation[ECMO],accompa-nied by major complications and comorbidity[MCC],50.00％),BC29(ventricular shunt and revision surgery,31.43％),BB21(craniotomy other than trauma,accompanied by MCC,27.56％),BB11(craniotomy of brain trauma,accompanied by MCC,26.32％),and GB1A(major surgery of esophagus,stomach,and duodenum,accompanied by major or moderate complications and comorbidity,16.00％).After RW adjustment,the DRG groups with the top five high incidence of HAI were ES21(respiratory system infection/inflammation,accompanied by MCC,5.89％),BR21(cerebral ischemic disease,accompanied by MCC,5.17％),FR11(heart failure,shock,accompanied by MCC,4.80％),BC29(4.57％)and AH11(3.57％).Conclusion Analyzing the incidence of HAI based on CMI and RW can help to identify key departments and disease groups for infection prevention and control,and provide reference for precise prevention and control of HAI in the new era.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.

With the growing emphasis on maternal and child oral health, the significance of managing oral health across preconception, pregnancy, and infancy stages has become increasingly apparent. Oral health challenges extend beyond affecting maternal well-being, exerting profound influences on fetal and neonatal oral development as well as immune system maturation. This expert consensus paper, developed using a modified Delphi method, reviews current research and provides recommendations on maternal and child oral health management. It underscores the critical role of comprehensive oral assessments prior to conception, diligent oral health management throughout pregnancy, and meticulous oral hygiene practices during infancy. Effective strategies should be seamlessly integrated across the life course, encompassing preconception oral assessments, systematic dental care during pregnancy, and routine infant oral hygiene. Collaborative efforts among pediatric dentists, maternal and child health workers, and obstetricians are crucial to improving outcomes and fostering clinical research, contributing to evidence-based health management strategies.
