Objectives: . The prognostic value of the pretreatment albumin-to-alkaline phosphatase ratio (AAPR) in head and neck cancer (HNC) remains uncertain. This meta-analysis aimed to evaluate the predictive role of AAPR for survival outcomes in patients with HNC. Methods: . A comprehensive search of the Cochrane Library, PubMed, and Embase databases was conducted to identify relevant studies published up to July 30, 2024. We included studies on AAPR and survival outcomes in HNC patients. Results: . Eight studies comprising 1,737 HNC patients were analyzed using random-effects models. Lower AAPR values were significantly correlated with worse overall survival (hazard ratio [HR], 2.08), progression-free survival (HR, 2.00), and disease-free survival (HR, 2.18). Sensitivity analyses confirmed the robustness of these results, with no significant publication bias detected. Conclusion . Our findings suggest that pretreatment AAPR could serve as a valuable and cost-effective prognostic indicator in HNC, potentially aiding clinicians in risk stratification and treatment decision-making. However, additional validation studies are warranted to confirm its clinical applicability.

Objective A scoping review of studies on pulmonary prehabilitation in cardiac surgery patients was conducted to provide evidence support for the construction of a preoperative pulmonary rehabilitation program for cardiac surgery patients that suitable for China's national conditions.Methods In accordance with the scope review's research methodologies,databases including PubMed,Embase,Web of Science,CINAHL,CNKI and Wanfang were searched by the computer for relevant studies.The deadline for retrieval is from the establishment of databases to June,2024.The included literature was systematically analyzed.Results 26 articles were finally included.Among them,4 were quasi-experiment studies,while the other 22 were randomized controlled trials.Forms of the intervention included comprehensive breathing exercises,inspiratory muscle training,positive expiratory pressure,incentive spirometer training and balloon blowing training.The intervention initiation ranged from 10 weeks to 1 day preoperatively;the outcome measures included postoperative pulmonary complications,lung function metrics,the 6-Minute Walk Test,duration of mechanical ventilation,length of hospital stay,patient-reported outcomes and so on.Conclusion There remains a deficiency in standardized protocols for preoperative pulmonary rehabilitation training among patients undergoing cardiac surgery.High-quality studies should be conducted,and intervention strategies for pulmonary prehabilitation in cardiac surgery patients should be optimized and a unified evaluation standard system should be established.

Objective To analyze the clinical characteristics and prognosis of Pseudomonas aeruginosa peritoneal dialysis-associated peritonitis(PaeP).Methods Peritoneal dialysis-associated peritonitis(PDAP)patients who were followed up in the nephrology outpatient department of a hospital from January 2019 to December 2020 were analyzed retrospectively.According to bacterial culture results,patients were divided into the PaeP group and non-PaeP group.Clinical characteristics of PaeP patients and antimicrobial susceptibility testing results of Pseudomonas aeruginosa were analyzed,clinical manifestations,laboratory test results,and prognosis of two groups of patients were compared.Results A total of 124 peritoneal dialysis patients were included in analysis,164 cases of peritoni-tis occurred,16 cases were in the PaeP group and 148 in the non-PaeP group.11 patients developed 16 episodes of Pseudomonas aeruginosa infection,accounting for 8.9％of PDAP patients.Among them,4 patients had peritoneal dialysis catheter exit-site infection,with 5 recurrence cases,1 case cured,1 case died,and 9 cases were extubated.Among the extubated patients,1 withdrew dialysis,3 were recovered to peritoneal dialysis after hemodialysis,5 changed to permanently hemodialysis,with a technical failure rate of 54.5％.Compared with the non-PaeP group,patients in the PaeP group had a shorter dialysis time(13.83±4.92 vs 38.53±35.77 months).During the infection period,C-reactive protein levels were higher(96.61±6.17 vs 45.87±44.65 mg/L),while albumin levels were lower(25.62±4.42 vs 29.46±8.25 g/L).At the onset of infection,the proportion of polymorphonuclear cells in perito-neal dialysis fluid was relatively higher.On the 5th day of treatment,the negative conversion rate of white blood cell count in peritoneal dialysis fluid was relatively low.Differences were all statistically significant(all P＜0.05).The cure rate of patients in the PaeP group was lower than that in the non-PaeP group,the technical failure rate was higher than that in the non-PaeP group,both with statistically significant differences(both P＜0.05).There was no statistically significant difference in the mortality between two groups of patients(P＞0.05).Conclusion PaeP patients have severe clinical manifestations,poor clinical treatment prognosis,high recurrence and extubation rates.For patients with repeated episodes,resetting and replacing the tunnel after extubation is an effective means to re-duce technical failures.

Objective To characterize the features of patent foramen ovale(PFO)-related cryptogenic stroke using diffusion-weighted imaging(DWI)and to investigate the correlation between infarct size and cardiac CT characteristics of PFO.Methods A retrospective,consecutive cohort study was conducted on acute ischemic stroke patients admitted to Neurology Department of Xuanwu Hospital,Capital Medical University from January 2022 to September 2024.Patients were categorized into PFO group,arterio-arterial embolism(AAE)group,and atrial fibrillation(AF)group based on etiological diagnosis.Baseline clinical data,including age,height,body mass index,admission National Institutes of Health stroke scale(NIHSS)score,history of old cerebral infarction,hypertension,diabetes mellitus,coronary heart disease,dyslipidemia,and smoking history were collected and compared.All patients underwent head MR within 24 h of admission.DWI was used to analyze and compare infarct characteristics across the three groups,including lesion number(single or multiple),location(cortical+subcortical,deep white matter,cortical+subcortical+deep white matter,cerebellum+thalamus+brainstem),size(≥15 mm or＜15 mm,based on maximum transverse diameter;for multiple lesions,if any lesion had a maximum diameter≥15 mm,it was categorized as≥15 mm),infarcted vascular territory(anterior,posterior,or both circulations),and specific arterial supply(anterior cerebral artery,middle cerebral artery,posterior cerebral artery,basilar artery,posterior inferior cerebellar artery,superior cerebellar artery,anterior choroidal artery,or multiple arteries).Patients in the PFO group additionally underwent cardiac CT to measure PFO-related parameters:tunnel length,width,height,septum secundum thickness,and fossa ovalis length.Spearman correlation analysis was performed to evaluate the relationship between infarct size and PFO cardiac CT features.Results A total of 232 acute ischemic stroke patients were included(mean age[57±17]years,ranged 19-86 years;141 males,91 females),comprising 116 in the PFO group,36 in the AAE group,and 80 in the AF group.(1)The proportion of males in the PFO group was higher than that in the AF group,it was lower than that in the AAE group.The age,body mass index and proportions of patients with hypertension,diabetes,hyperlipidemia,coronary heart disease were all lower than those in the other two groups(both P＜0.016 7),while other baseline characteristics showed no significant differences(all P＞0.05).(2)The PFO group exhibited a higher proportion of multiple infarcts compared to the AAE group(83.62％[97/116]vs.61.11％[22/36],P＜0.016 7),but a lower proportion than the AF group(83.62％[97/116]vs.98.75％[79/80],P＜0.016 7).The PFO group also showed a significantly higher proportion of cortical+subcortical infarcts(47.41％[55/116]vs.11.11％[4/36]and 6.25％[5/80],respectively,both P＜0.016 7)and infarcts with a maximum diameter＜15 mm compared to both AAE and AF groups(66.38％[77/116]vs.36.11％[13/36]and 11.25％[9/80],respectively,both P＜0.016 7).Furthermore,the PFO group had a lower proportion of anterior circulation infarcts(27.59％[32/116]vs.69.44％[25/36]in AAE group and 67.50％[54/80]in AF group,both P＜0.016 7),but a higher proportion of posterior circulation infarcts(62.07％[72/116]vs.16.67％[6/36]in AAE group and 8.75％[7/80]in AF group,both P＜0.016 7).Specifically,middle cerebral artery infarcts were less common in the PFO group(18.97％[22/116]vs.66.67％[24/36]in AAE group and 52.50％[42/80]in AF group,both P＜0.016 7),while posterior cerebral artery infarcts were more common(48.28％[56/116]vs.8.33％[3/36]in AAE group and 8.75％[7/80]in AF group,both P＜0.016 7).(3)Spearman correlation analysis revealed that infarct size was negatively correlated with PFO tunnel length(rs=-0.429,P=0.029),fossa ovalis length(rs=-0.408,P=0.038),and septum secundum thickness(rs=-0.525,P=0.006),but not correlated with PFO width or height(both P＞0.05).Conclusions PFO-related cryptogenic stroke is predominantly characterized by multiple small infarcts,primarily located in the cortical+subcortical regions and posterior circulation.Infarct size was found to be negatively correlated with PFO tunnel length,fossa ovalis length,and septum secundum thickness.Comprehensive assessment integrating DWI and cardiac CT features may facilitate the identification of PFO-related stroke.These findings warrant further validation through larger,prospective studies.

Objective To study the efficacy of hemoperfusion(HP)in series with continuous renal replace-ment therapy(CRRT)integrated combined blood purification under extracorporeal citrate anticoagulation in the treatment of severe hypertriglyceridemic acute pancreatitis(HTG-AP).Methods A total of 62 patients with severe HTG-AP admitted to the Affiliated Hospital of Xuzhou Medical University from June 2022 to May 2024 were selected and randomly divided into control group and observation group,with 31 cases in each group.The control group was treated with conventional medical treatment+HP combined with CRRT staged combined blood purifica-tion treatment,and the observation group was treated with conventional medical treatment+HP in series with CRRT integrated combined blood purification treatment under extracorporeal citrate anticoagulation.The indexes and clinical efficacy before and 7 days after treatment were compared between the two groups.Results The single CRRT time of the observation group was longer than that of the control group,and the frequency of CRRT was less than that of the control group(P<0.05).There were no significant differences in the total CRRT time,single HP time,HP frequency and total HP time between the two groups(P>0.05).The blood routine,inflammatory factors,blood biochemistry and clinical scores of the two groups after treatment were improved compared with those before treatment(P<0.05).After treatment,the hemoglobin(Hb)and platelet count(Plt)of the observation group were higher than those of the control group(P<0.05),and there were no significant differences in other indexes of blood routine,inflammatory factors,blood biochemistry and clinical scores between the two groups(P>0.05).There were no significant differences in clinical indexes,prognosis and complications between the two groups(P>0.05).Conclusions Without affecting the efficacy,HP in series with CRRT integrated combined blood purification under extracorporeal citrate anticoagulation in the treatment of severe HTG-AP can prolong the use time of CRRT blood filter and pipeline,reduce the use of consumables,reduce the risk of bleeding,and avoid multiple catheter removal of HP and CRRT operation separately,and reduce the risk of related infection.It is worthy of clinical application.

Wound healing is a dynamic physiological process involving haemostasis,inflammation,pro-liferation and tissue remodeling.Skin injuries,such as diabetic foot ulcers,venous ulcers,and pressure ulcers,are difficult to heal and impose a serious physical and psychological burden on patients,and tra-ditional treatments are difficult to address such problems.In recent years,Chinese herbal medicine-de-rived extracellular vesicles(CHMEVs)have shown promising potential in the field of wound repair and drug delivery due to their excellent biocompatibility,low immunogenicity and high safety.CHMEVs are nano-like particles enriched with herbal small molecule compounds,proteins and metabolites,and are a-ble to cross biological barriers and effectively regulate intercellular communication to promote tissue re-pair.In this review,the isolation and extraction methods of CHMEVs and their roles in wound repair are reviewed,and the prospects and challenges of their clinical applications are discussed.The combination of engineered modification and biomaterials of CHMEVs further expands their potential for application in precision medicine and provides a new idea for the treatment of hard-to-heal wounds in the future.

Objective:To investigate the molecular mechanisms of bexarotene in treating double hit lymphoma(DHL)based on Weighted Gene Co-expression Network Analysis(WGCNA),thereby providing potential targets and experimental evidence for DHL treatment.Methods:The gene expression datasets GSE44164 and GSE43677 were downloaded from the Gene Expression Omnibus(GEO)database,and differentially expressed genes(DEGs)were identified.WGCNA was employed to identify gene modules associated with DHL.A protein-protein interaction(PPI)network was constructed to screen for key hub genes.Drug-gene association analysis was conducted using the EpiMed platform to identify potential targeted drugs for DHL.The effects of bexarotene on DHL cell proliferation and key protein expression were evaluated using the CCK-8 assay and Western blotting(WB),and its effects on cell apoptosis was evaluated using flow cytometry.Results:WGCNA identified a turquoise module highly associated with DHL,and 10 hub genes(COL1A2,COL3A1,MMP2,COL5A2,DCN,BGN,FN1,MMP9,FBN1,and LUM)were screened from the PPI network.Drug association analysis nominated bexarotene as a potential therapeutic agent.In vitro validation demonstrated that bexarotene significantly inhibited U2932 cell viability(P<0.05),promoted cell apoptosis(P<0.001),and downregulated c-Myc and COL1A2 expression(P<0.05).Conclusion:Bexarotene may exert anti-DHL effects by suppressing the c-Myc signaling pathway and modulating extracellular matrix-related genes.Further studies are warranted to validate its in vivo efficacy and potential for combination therapy.
