Objective To explore the clinical characteristics of organ donors in the intensive care unit (ICU), analyze the impact of comprehensive ICU treatment on organ function maintenance and donation efficiency, and provide data support for optimizing organ donation management strategies. Methods A retrospective analysis was conducted on the data of 263 donors who underwent organ donation after ineffective active treatment in the ICU of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2020 to January 2024. The clinical characteristics, main therapeutic measures in the ICU, and organ donation situations were analyzed. Results The 263 organ donors had an out-of-hospital hospitalization duration of 2 (1, 5) days and an in-hospital hospitalization duration of 4 (3, 6) d. The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score at admission was (21±5). Among them, 16.7% had a history of cardiopulmonary resuscitation, 30.4% had a history of hypertension, and 48.7% had a history of cranial surgery. The duration of enteral nutrition provided in the ICU was 18 (8, 32) h, with daily energy provision of 160 (0, 320) kcal, parenteral nutrition provided non-protein energy of 877 (710, 1 058) kcal daily. Fiberoptic bronchoscopy was performed 0.25 (0, 0.50) times a day. Continuous renal replacement therapy (CRRT) was performed in 90.1% of the cases, with an average daily duration of 10 (6, 16) h. The daily dosage of human albumin was 40 (30, 50) g, and the daily dosage of methylprednisolone was 120 (80, 160) mg. The most commonly used empirical anti-infection regimens included cefoperazone-sulbactam in 59 cases (22.4%), meropenem combined with vancomycin in 31 cases (11.8%), and piperacillin-tazobactam in 29 cases (11.0%). The most commonly used goal-directed anti-infection adjustment regimen was meropenem combined with vancomycin in 21 cases (8.0%). After comprehensive treatment in the ICU, cardiac function, some liver functions, some coagulation functions, renal function, electrolytes, and infection indicators improved. A total of 981 organs were donated by the 263 organ donors, with 23 organs discarded. The average organ yield rate was 3.64, and the organ utilization rate was 97.7%. Conclusions Comprehensive ICU treatment may significantly improve the cardiac function, some liver functions, coagulation functions, and infection indicators of organ donors, enhance the effect of organ function maintenance, and provide an effective guarantee for optimizing organ donation management in the ICU and improving organ utilization rates.

ObjectiveTo investigate the prevalence and influencing factors of overweight， obesity and central obesity among elderly residents in Xuhui District， and to analyze the epidemiological status of central obesity in elderly people with different body mass indexes. MethodsThe third round of health status and health service utilization monitoring data in Xuhui District was used. The information collected from questionnaire survey and physical examination were analyzed. SPSS 20.0 software was used for χ² test， trend χ² test and multinominal logistic regression analysis. Results5 096 survey subjects were included. The prevalence of overweight， general obesity， and central obesity in the residents aged 60 and above in Xuhui District were 34.3%， 6.5%， and 29.2%， respectively. There was gender difference in the rates of overweight， obesity， and central obesity among the residents. The overweight and central obesity rates in males were higher than those in females， while the obesity rate was lower than that in females （P<0.05）. Multinominal logistic regression analysis showed that in comparison with the normal weight non-central obesity group drinking only at party （OR=1.729， 95%CI： 1.184‒2.525）， and hypertension （OR=1.637， 95%CI： 1.305‒2.053）， were highly associated with normal weight with central obesity. Aged 60‒ years （OR=1.589， 95%CI： 1.190‒2.120）， aged 70‒ years （OR=1.763， 95%CI： 1.327‒2.342）， male （OR=1.379， 95%CI： 1.134‒1.676）， hypertension （OR=2.231， 95%CI： 1.878‒2.649）， former smokers （OR=1.437， 95%CI： 1.027‒2.011）， drinking at party only （OR=1.491， 95%CI： 1.107‒2.006）， and drinking ≥3 times per week （OR=1.611， 95%CI： 1.116‒2.325）， were highly associated with overweight combined with central obesity. Aged 60‒ years （OR=3.817， 95%CI： 2.251‒6.474）， aged 70‒ years （OR=3.084， 95%CI： 1.838‒5.175）， hypertension （OR=3.683， 95%CI： 2.753‒4.929）， diabetes （OR=2.085， 95%CI： 1.511‒2.878）， former smokers （OR=1.835， 95%CI： 1.043‒3.226）， were highly associated with compound obesity. Central obesity was found in the elderly residents with different BMI categories， and the rate of central obesity increased with the increase of BMI grade. ConclusionThe prevalence of overweight， obesity and central obesity among the elderly aged 60 years and above in Xuhui District is not optimistic. Attention should be paid to the elderly under 80 years old who are with hypertension and/or diabetes， alcohol consumption， low educational level and not doing physical exercise. Especially for the central obesity population with normal BMI， measures should be taken to prevent and intervene the occurrence of obesity and related diseases.

BACKGROUND:Shujin Jiannao Prescription is an empirical formula for the treatment of cerebral palsy in Dongzhimen Hospital,Beijing University of Chinese Medicine,with clear clinical efficacy,but the specific mechanism needs to be elucidated. OBJECTIVE:To explore the possible mechanism of Shujin Jiannao Prescription in treating cerebral palsy. METHODS:Sixty-four 7-day-old Sprague-Dawley rats were randomly divided into a normal group(n=12)and a model group(n=52).An animal model was established by the Rice-Vannucci method.After successful modeling,52 model rats were randomly divided into control model group(n=12),minocycline group,and the low-,medium-,and high-dose groups of the Shujin Jiannao Prescription(n=10 per group).Rats in the minocycline group were given 40 mg/kg·d minocycline by gavage;rats in the low-,medium,and high-dose groups were given 4,8,and 16 g/kg·d Shujin Jiannao Prescription granules by gavage,respectively;and rats in the normal group and control model group were given an equal dose of normal saline by gavage.Medication in each group was given once a day for 1 week.The rats in each group were evaluated behaviorally using suspension test,abnormal involuntary movement score,and Bederson score.The pathological changes of the cerebral cortex were observed by hematoxylin-eosin staining.The levels of tumor necrosis factor α,interleukin 1β,and interleukin 10 in the cerebral cortex were determined using ELISA.The positive expressions of Janus kinase 2(JAK2),phosphorylated Janus kinase 2(p-JAK2),phosphorylated signal transducer and activator of transcription 3(p-STAT3)in the cerebral cortex were detected using immunohistochemistry.The protein expression levels of JAK2,p-JAK2,and p-STAT3 were detected using western blot. RESULTS AND CONCLUSION:Compared with the normal group,the suspension test score and involuntary movement score were decreased in the control model group(P＜0.01 or P＜0.05).The pathological results showed structural disruption of nerve cells,formation of large numbers of vacuoles,cell swelling,and increased intercellular space in the control model group.In addition,the expressions of tumor necrosis factor α and interleukin 1β in the cerebral cortex were significantly increased(P＜0.01),the expression of interleukin 10 was decreased(P＜0.05),and the protein expressions of JAK2,p-JAK2,and p-STAT3 in the cerebral cortex were significantly increased(P＜0.01)in the control model group compared with the normal group.Compared with the model group,minocycline and Shujin Jiannao Prescription at each dose could improve the behavioral indexes of rats(P＜0.01 or P＜0.05)and ischemic-hypoxic pathological changes were attenuated,with only a small amount of necrotic nerve cells and a few vacuoles,and reduced intercellular space.Moreover,the expressions of tumor necrosis factor α and interleukin 1β in the cerebral cortex were decreased in each drug group compared with the control model group(P＜0.05),while the protein expressions of JAK2,p-JAK2,and p-STAT3 in the cerebral cortex were significantly decreased(P＜0.01).The most obvious improvement was observed in the high-dose Shujin Jiannao Prescription group.To conclude,Shujin Jiannao Prescription can inhibit inflammation in the cerebral cortex of rats with hypoxic-ischemic brain injury.The mechanism may be related to the regulation of the JAK2/STAT3 signaling pathway.

BACKGROUND:Perinatal hypoxic-ischemic brain injury is one of the most common causes of cerebral palsy.Shujin Jiannao Prescription is an experienced formula for treating cerebral palsy and improving blood supply to the brain developed by the Dongzhimen Hospital,Beijing University of Chinese Medicine. OBJECTIVE:To explore the possible mechanism of Shujin Jiannao Prescription in treating hypoxic-ischemic cerebral palsy. METHODS:Sixty-four 7-day-old Sprague-Dawley rats were randomly divided into six groups.There were 12 rats in each of the control and model groups as well as 10 animals in each of the minocycline group,and the low-,medium-,and high-dose groups of Shujin Jiannao Prescription.The neonatal rat ischemic-hypoxic cerebral palsy model was established in all groups except for the control group.After successful modeling,rats in each drug group were respectively gavaged with minocycline and Shujin Jiannao Prescription at a dose of 4,8,and 16 g/kg per day for 1 week.Body mass of rats was measured and behavioral changes were detected before and after drug administration.Hematoxylin-eosin staining was used to observe the histomorphology of hippocampal CA1 region of rat brain tissue,and immunohistochemistry and western blot were used to detect the expression levels of Bcl-2,Bax,and Caspase-3 in the brain tissue of rats. RESULTS AND CONCLUSION:Compared with the model group,medium-and high-dose Shujin Jiannao Prescription significantly increased the body mass of rats(P<0.05).Compared with the model group,minocycline effectively prolonged the suspension time of ischemic-hypoxic cerebral palsy rats(P<0.05),while medium-and high-dose Shujin Jiannao Prescription significantly prolonged the suspension time,shortened the inclined plane test time,and increased the Longa score of rats(P<0.05).The pathological results showed that after drug intervention,only a small number of neuronal cells in the brain tissue of rats were necrotic,the cells were more neatly arranged,the cell structure was more complete,and only part of the cell nuclei became smaller.Compared with the model group,minocycline and medium-and high-dose Shujin Jiannao Prescription reduced the expression of Bax Caspase-3(P<0.05),medium-and high-dose Shujin Jiannao Prescription increased the expression of Bcl-2(P<0.05),and Bcl-2/Bax protein expression was increased in minocycline and three Shujin Jiannao Prescription groups(P<0.05).In addition,the protein expression was increased in a dose-dependent manner after intervention with Shujin Jiannao Prescription,and there was no significant difference between the minocycline and three Shujin Jiannao Prescription groups(P>0.05).To conclude,the mechanism by which Shujin Jiannao Prescription treats ischemic-hypoxic cerebral palsy in rats may be to enhance the expression of anti-apoptotic protein Bcl-2,inhibit the expression of pro-apoptotic protein Bax,and reduce the expression of Caspase-3,ultimately inhibiting the apoptosis of hippocampal neuronal cells in rats with cerebral palsy.Within a certain range,the higher dose of Shujin Jiannao Prescription indicates the better therapeutic effect,and the high-dose Shujin Jiannao Prescription is as effective as minocycline.

BACKGROUND:At present,there are some limitations in evaluating the severity of acute spinal cord injury,and a rapid and accurate evaluation method is urgently needed. OBJECTIVE:To analyze the correlation between the expression levels of serum oxidative stress and nerve injury indexes and the severity of the disease in patients with acute spinal cord injury. METHODS:A total of 65 patients were included in the study from August 2020 to May 2022,including 32 patients in the experimental group(acute spinal cord injury)and 33 patients in the control group(simple spinal fracture).American Spinal Injury Association(ASIA)Impairment Scale and neurological function score were evaluated within 8 hours of admission.Meanwhile,serum levels of superoxide dismutase,malondialdehyde,glutathione,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase were detected and compared between the two groups.The correlation between the expression levels of the above serological indicators in serum and ASIA impairment grade and AISA neural function score was analyzed. RESULTS AND CONCLUSION:The average serum levels of superoxide dismutase and glutathione in the experimental group were significantly lower than those of the control group(P<0.001),while the average serum levels of malondialdehyde,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase in the experimental group were higher than those of the control group(P<0.01).The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with the damage grade of AISA(r=0.862 4,0.849 3,P<0.01),while the serum levels of malondialdehyde,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with the damage grade of AISA(r=-0.866 1,-0.638 1,-0.746 6,P<0.001),and the serum level of nitric oxide was not significantly correlated with the damage grade of AISA(r=-0.177 5,P>0.05).The serum level of glutathione in the experimental group was positively correlated with AISA sensory function scores(r=0.569 9,P<0.001),while the serum levels of malondialdehyde,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA sensory function scores(r=-0.574 1,-0.099 2,-0.708 6,P<0.05),and the serum levels of superoxide dismutase and nitric oxide were not significantly correlated with AISA sensory function scores(r=0.230 8,-0.376 2,P>0.05).The serum levels of superoxide dismutase and glutathione in the experimental group were positively correlated with ASIA motor function scores(r=0.380,0.524 7,P<0.05);the serum levels of malondialdehyde,glial fibrillary acidic protein and neuron-specific enolase were negatively correlated with AISA motor function scores(r=-0.577 9,-0.452 2,-0.662 8,P<0.05);and the level of nitric oxide had no significant correlation with AISA motor function scores(r=-0.049 7,P>0.05).To conclude,the serum levels of superoxide dismutase,malondialdehyde,glutathione,nitric oxide,glial fibrillary acidic protein and neuron-specific enolase in serum of patients with acute spinal cord injury are significantly correlated with ASIA impairment grade and ASIA neural function score,which could be used as biomarkers for early clinical assessment of disease severity.

Objective To identify factors associated with gastrointestinal heat retention in preschool children,and to provide a foundational understanding for future clinical investigations. Methods A case-control study was performed,which involved children from kindergartens in the Longgang District of Shenzhen City,Guangdong Province,from May to July 2021. Using the Children's Gastrointestinal Heat Retention Diagnostic Self-assessment Scale,subjects were allocated into a case group (children diagnosed with gastrointestinal heat retention) and a control group (children without this condition). An online survey was used to collect data on dietary behaviors,caregivers' feeding behaviors,early antibiotic use,daily routines,and birth conditions. SPSS 27.0 software was used to facilitate precise sociodemographic matching and paired logistic regression analysis to explore the association between gastrointestinal heat retention and the above factors. Results From the analysis of 51,252 matched cases,the study found that several factors contributed to an increased risk of gastrointestinal heat retention. These factors included reduced food intake compared to peers,reports of picky eating by caregivers,distractions during meals,pronounced dietary preferences,disinterest in food,meal durations ≥ 25 min,reluctance to sample new foods,consistent refusal of specific food types for over one month,irregular meal locations,coercive feeding practices,use of micronutrient supplements,allowing children too much freedom in food choice,persuading children to eat,infrequent encouragement to experiment with new foods,early antibiotic introduction,inadequate sleep,and premature birth (P<0.05). In contrast,exclusive breastfeeding in the first six months,engagement in moderate to massive physical activity,and regular napping patterns were associated with a reduced risk of gastrointestinal heat retention (P<0.05). Conclusion The suboptimal dietary habits,improper feeding practices,insufficient physical activity,inadequate sleep,and premature antibiotic exposure may be significant risk factors for gastrointestinal heat retention. Future research dedicated to unraveling the cause of gastrointestinal heat retention should prioritize these elements.

Objective:To examine the impact of intrinsic capacity(IC), comorbidity, and their interaction on the occurrence of adverse outcomes in community-dwelling older adults.Methods:This 2-year observational cohort study included 230 residents aged 75 and above who lived in the Beijing Taikang Yanyaun community active area from June to August 2018.The study evaluated the IC scale, Charlson comorbidity index(CCI), and activity of daily living(ADL).In September 2020, adverse outcomes such as functional decline(defined as a decline of at least one point on the ADL scores at 2-year follow-up compared with baseline)and falls were assessed.The structure equation model(SEM)path analysis was employed to examine the direct and indirect effects of IC and CCI on adverse outcomes.Results:Among the 212 older adults who completed a 2-year follow-up, aged 75-93(mean age 83.8±4.4)years, 59.4%(126 cases)were female.Out of these participants, 51.4%(109 cases)experienced functional decline and 33.5%(71 cases)had falls.Path analysis revealed that the direct effects of IC on functional decline and falls were significantly positive, with standardized coefficients of 0.430 and 0.369, respectively.However, the effect of CCI was not found to be significant.The multi-variable Logistic regression model showed that the total effect of IC on functional decline and falls remained significantly positive, with values of 1.184 and 0.915, respectively.CCI acted as a mediating factor, with indirect effects on functional decline and falls accounting for 5.4% and 0.8%, respectively.In terms of the relationship between age and adverse outcomes, the indirect effect of IC was significantly higher than that of CCI(functional decline: 0.192 vs.0.037; falls: 0.158 vs.0.017). Conclusions:The maintenance of IC in the health management of community-dwelling older adults should be given more attention as it can significantly affect the incidence of functional decline and falls.Comorbidity, on the other hand, has a weaker influence.

Objective To investigate the molecular mechanism of Shema Zhichuan Liquid in the treatment of neutrophilic asthma(NA)based on network pharmacology and in vivo experiments.Methods(1)The TCMSP,literature search and Swiss ADME and Swiss Target Prediction databases were used to search and screen the active components and their targets of Shema Zhichuan Liquid.OMIM,GeneCards,DisGeNET and DrugBank databases were used to search and screen NA disease-related targets.The intersection of the active components and NA disease-related targets of Shema Zhichuan Liquid was obtained through the microbiology platform to obtain the potential targets of Shema Zhichuan Liquid for the treatment of NA(common targets).Cytoscape 3.8 software was used to construct the network of"Chinese medicinals-active components-potential targets".The PPI network of potential targets was established by STRING database,and the core targets were obtained by analysing the built-in Mcode plug-in.The Metascape platform was used to enrich the gene ontology(GO),Kyoto Encyclopaedia of Genes and Genomes(KEGG)pathways for the potential targets.(2)BALB/C mice were acclimatised and fed for 1 week and randomly divided into a blank group,NA model group,low-dose group(2.5 g·kg-1)and high-dose group of Shema Zhichuan Liquid(10 g·kg-1),and control group of Dexamethasone(1 mg·kg-1);the NA mouse model was replicated by intraperitoneal injection of sensitizer(OVA+CFA)and nebulized inhalation excitation.OVA/CFA(20 μg OVA+75 μg CFA,0.3 mL)was injected intraperitoneally to sensitize on days 0,7 and 14 respectively,and 5%OVA suspension was nebulized on days 21-30(8 mL each time,40 minutes each time,once a day);1 hour before nebulisation,each group was administered by gastric gavage,and the Dexamethasone control group was administered by intraperitoneal injection once a day.The pathological changes of mouse lung tissue were observed by HE staining;IL-8 content in alveolar lavage fluid was detected by ELISA;mRNA expression levels of NLRP3 and CXCR2 were detected by RT-qPCR;and p-mTOR protein expression levels was detected by immunohistochemistry.Results(1)A total of 826 active component targets and 154 NA disease-related targets were obtained,and 51 potential targets(common targets)for the treatment of NA were obtained from the intersection of the active component and the NA disease-related targets of Shema Zhichuan Liquid.Through the network analysis of"Chinese medicinals-active components-potential targets",quercetin,lignocerotoxin,kaempferol,stigmasterol,naringenin and other key active components were obtained.The PPI network analysis of potential targets yielded 29 core targets,including AKT1,IL6,TNF,EGFR,NLRP3,RELA,MIF,CXCR2,VEGFA,etc..The GO functional enrichment analysis yielded 882 biological process entries,33 cellular component entries,and 61 molecular function entries;KEGG analysis yielded 142 signaling pathways,mainly involving TNF signaling pathway,influenza A signaling pathway,Toll-like receptor pathway,MAPK signaling pathway,mTOR signaling pathway and so on.(2)Results of animal experiments:compared with the blank group,mice in the NA model group showed obvious damage to the airway mucosa,structural disorders,a large number of inflammatory cells infiltration,mucosal congestion,oedema,obvious thickening of the alveolar wall,and narrowing of the alveolar lumen;the level of the inflammatory factor IL-8 in the alveolar lavage fluid was significantly elevated(P＜0.05);the mRNA expressions of NLRP3 and CXCR2 in the lung tissues of the mice were significantly up-regulated(P＜0.01),and the protein expression of p-mTOR was significantly increased.Compared with the NA model group,the structural arrangement of bronchial epithelial cells in the mice in the low-and high-dose groups of Shema Zhichuan Liquid was slightly disordered,with a small amount of inflammatory cell infiltration around the airways and blood vessels,and the congestion and edema of the bronchial mucosa were significantly reduced;the mRNA expression of CXCR2 in the lung tissues of the mice was significantly down-regulated(P＜0.01),and the level of expression of p-mTOR protein was significantly reduced.The IL-8 level in the vesicular lavage fluid of mice in the high-dose group was significantly reduced(P＜0.05);the mRNA expression of NLRP3 in the lung tissue of mice in the low-dose group was significantly down-regulated(P＜0.05).Conclusion The therapeutic effect of Shema Zhichuan Liquid on NA may be achieved through the key active components,such as quercetin,lignocerol and kaempferol,acting on the core targets,such as NLRP3 and CXCR2,and regulating the key signaling pathways,such as the TNF signaling pathway,the MAPK signaling pathway,the Toll-like signaling pathway,and the mTOR pathway.

Objective To explore the therapeutic mechanism of Modified Lugen Formula(Phragmitis Rhizoma,Cicadae Periostracum,Batryticatus Bombyx,Lonicerae Japonicae Flos,Glycyrrhiza,Menthae Haplocalycis Herba,Notopterygii Rhizoma et Radix,Puerariae Lobatae Radix,Bupleuri Radix)in treating influenza from the virus-host interaction interface.Methods The phytocompounds were first collected from the HERB database,and then potential active compounds were screened out by Lipinski's rules of five.The targets of active compounds were further predicted through the SwissTargetPrediction platform.Differentially expressed genes(DEGs)were determined from the human H1N1 influenza dataset GSE90732 available in the Gene Expression Omnibus database(GEO).H1N1-Homo sapiens-related protein-protein interactions(PPIs)were gathered from the Pathogen-Host Interaction Search Tool(PHISTO).The above mentioned bioinformatic datasets were integrated.Then a PPI network and a Formula-virus-host interaction network were constructed using Cytoscape.Functional enrichment analyses were performed by using R software.Finally,molecular docking was carried out to evaluate the binding activities between the key compounds and targets.Results A total of 1 252 active compounds,1 415 targets,951 influenza-related DEGs,and 10 142 H1N1-Homo sapiens-related PPIs were obtained.There were 72 intersection targets between the Modified Lugen Formula and influenza.Functional enrichment analyses showed that these targets are closely related to host defense and programmed cell death.The network topological analysis showed that active compounds in the Modified Lugen Formula,such as oleanolic acid,γ-undecalactone,and longispinogenin,regulate viral proteins M2,NA,NS1,and HA and/or the host factors HSP90AA1,NRAS,and ITGB1,thus exert therapeutic effect.Molecular docking results confirmed that these compounds had a good binding ability with the targets.Conclusion Multiple active ingredients in Modified Lugen Formula directly target influenza virus proteins and/or host factors,thereby play an anti-influenza role in multiple dimensions,including inhibiting virus replication,regulating host defense and cell death.This study provides a theoretical basis for further experimental analysis of the action mechanism of the Modified Lugen Formula in treating influenza.

This paper explores the intersection and integration of narrative medicine and clinical spiritual care,especially the importance and value of spiritual narrative in medical services.Spiritual narrative is based on the three elements of narrative medicine,combined with the professional competence of clinical spiritual care,to achieve multi-angle attention to patients'physiology,psychology,society,and spirit.The connections and situations between individuals in the disease story are reproduced in the spiritual narrative,allowing the narrator to deeply understand the relationship between themselves,others,and natural events from a more diverse perspective,thereby enhancing the role identity and professional happiness of doctors,and ultimately promoting the narrator's exploration of their own inner selves and understanding of life philosophy.Integrating narrative medicine into undergraduate teaching,research,and clinical practice of the clinical spiritual care program at Hunan Cancer Hospital,conducting spiritual narrative,is of great significance for improving the empathy and communication skills of medical students and clinical medical staff,promoting their thinking and understanding of the meaning of life,and enhancing their patient-centered clinical critical thinking ability.
