    63-70页
    查看更多>>摘要：Sepsis is a potentially fatal condition characterized by the failure of one or more organs due to a disordered host response to infection.The development of sepsis is closely linked to immune dysfunc-tion.As a result,immunotherapy has gained traction as a promising approach to sepsis treatment,as it holds the potential to reverse immunosuppression and restore immune balance,thereby improving the prognosis of septic patients.However,due to the highly heterogeneous nature of sepsis,it is crucial to carefully select the appropriate patient population for immunotherapy.This review summarizes the current and evolved treatments for sepsis-induced immunosuppression to enhance clinicians'under-standing and practical application of immunotherapy in the management of sepsis.

    查看更多>>摘要：Purpose:The role of topical vancomycin in fracture-related infection(FRI)is debatable.Very few studies have reported their efficacy in open and high-risk extremity fractures.This study aimed to assess topical vancomycin's role in reducing FRI in closed fractures undergoing open surgical intervention with an implant.Methods:This prospective randomized cohort study was carried out between February 2021 to January 2022.Patients with isolated closed fractures,who were planned for open reduction and internal fixation within 2 weeks from the time of injury were included for this study.The data collected included age,gender,socioeconomic status,mechanism of injury,diagnosis,Tscherne classification,and time interval to take up for surgery.Patients were randomized into the intervention and control groups using the block randomization technique.The control group received only systemic antibiotic prophylaxis,whereas the intervention group received topical application of vancomycin powder in the surgical wound alongside systemic antibiotic prophylaxis.The primary outcome measure was the incidence of FRI among these individuals.Clinical and radiological findings and culture reports(in cases with infection)were recorded during the post-operative period and at 6 weeks of follow-up.All relevant statistical calculations were done using STATA statistical/data analysis-parallel edition version 16.0(StataCorp LLC).The quantitative variables like age and duration of the surgery were assessed for normalcy by Shapiro-Wilk W test.An independent samples t-test with equal variances was applied to the age data.Fisher's exact test was used for the analysis of the primary outcome measure(presence of FRI following surgery),and"Risk of FRI"and"Risk difference"between the 2 groups was calculated.The strength of the association between qualitative variables was assessed using the Fisher's exact and Chi-square tests,respectively.Results:There were 88 patients included in this study.No statistical significance was found about FRI between both groups(p=0.494).At 6 weeks following surgery,no incidence of infection was observed in the intervention group.Two infections(4.5％)were found in the control group,with positive cultures reported in one of them but none in the treatment group.Radiologically,15.9％of patients in the control group showed lysis around the implant compared to 2.3％in the intervention group.Impaired fracture healing was observed in 22.7％of patients in the intervention group compared to 15.9％in the control group.Conclusion:Applying topical vancomycin in closed fractures undergoing open reduction and internal fixation does not significantly reduce the incidence of FRI until the end of 6 weeks following surgery.

    查看更多>>摘要：Purpose:To investigate which scoring system is the most accurate tool in predicting mortality among the infected patients who present to the emergency department in a middle-income country,and to validate a new scoring system to predict bacterial infections.Methods:This was a retrospective,single-center study among patients who were admitted via the emergency department of a public hospital.All patients who were started on antibiotics were included in the study,while patients aged＜18 years were excluded.Data collected includeding patients'de-mographics,vital signs and basic laboratory parameters like white blood cell count and creatinine.The sensitivity and specificity of different scoring systems were calculated as well as their negative and positive predictive values.Logistic regression was used to derive a novel early warning system for bacterial infections.The area under the receiver operating characteristic(AUROC)was computed for each scoring model.Results:In total,109 patients were included in this study.The quick sequential organ failure assessment(qSOFA),search out severity and rapid acute physiology score had the highest AUROC(≥ 0.89)for pre-dicting mortality,while qSOFA and universal vital assessment were the simplest scoring systems with an AUROC＞0.85;however,these scoring systems failed to predict whether patients were truly infected.The INFECTIONS(short for impaired mental status,not conscious,fast heart rate,elevated creatinine,high temperature,on inotrope,low oxygen,high neutrophils and high sugar)model reached an AUROC of 0.88 to more accurately predict the infectious state of a patient.Conclusions:Middle-income countries should use the qSOFA or universal vital assessment score to identify the sickest patients in emergency department.The INFECTIONS score may help recognize pa-tients with bacterial infections,but it should be further validated in multiple countries prior to widely use.

    A newly proposed heatstroke-induced coagulopathy score in patients with heat illness:A multicenter retrospective study in China

    Qing-Wei LinLin-Cui ZhongLong-Ping HeQing-Bo Zeng...
    83-90页
    查看更多>>摘要：Purpose:In patients with heatstroke,disseminated intravascular coagulation(DIC)is associated with greater risk of in-hospital mortality.However,time-consuming assays or a complex diagnostic system may delay immediate treatment.Therefore,the present study proposes a new heatstroke-induced coagulopathy(HIC)score in patients with heat illness as an early warning indicator for DIC.Methods:This retrospective study enrolled patients with heat illness in 24 Chinese hospitals from March 2021 to May 2022.Patients under 18 years old,with a congenital clotting disorder or liver disease,or using anticoagulants were excluded.Data were collected on demographic characteristics,routine blood tests,conventional coagulation assays and biochemical indexes.The risk factors related to coagulation function in heatstroke were identified by regression analysis,and used to construct a scoring system for HIC.The data of patients who met the diagnostic criteria for HIC and International Society on Thrombosis and Haemostasis defined-DIC were analyzed.All statistical analyses were performed using SPSS 26.0.Results:The final analysis included 302 patients with heat illness,of whom 131(43.4％)suffered from heatstroke,including 7 death(5.3％).Core temperature(OR=1.681,95％CI 1.291-2.189,p＜0.001),prothrombin time(OR=1.427,95％CI 1.175-1.733,p＜0.001)and D-dimer(OR=1.242,95％CI 1.049-1.471,p=0.012)were independent risk factors for heatstroke,and therefore used to construct an HIC scoring system because of their close relation with abnormal coagulation.A total score ≥ 3 indicated HIC,and HIC scores correlated with the score for International Society of Thrombosis and Hemostasis-DIC(r=0.8848,p＜0.001).The incidence of HIC(27.5％)was higher than that of DIC(11.2％)in all of 131 heatstroke patients.Meanwhile,the mortality rate of HIC(19.4％)was lower than that of DIC(46.7％).When HIC developed into DIC,parameters of coagulation dysfunction changed significantly:platelet count decreased,D-dimer level rose,and prothrombin time and activated partial thromboplastin time prolonged(p＜0.05).Conclusions:The newly proposed HIC score may provide a valuable tool for early detection of HIC and prompt initiation of treatment.

    97-106页
    查看更多>>摘要：Purpose:Acute kidney injury(AKI)is one of the most common functional injuries observed in trauma patients.However,certain trauma medications may exacerbate renal injury.Therefore,the early detection of trauma-related AKI holds paramount importance in improving trauma prognosis.Methods:Qualified datasets were selected from public databases,and common differentially expressed genes related to trauma-induced AKI and hub genes were identified through enrichment analysis and the establishment of protein-protein interaction(PPI)networks.Additionally,the specificity of these hub genes was investigated using the sepsis dataset and conducted a comprehensive literature review to assess their plausibility.The raw data from both datasets were downloaded using R software(version 4.2.1)and processed with the"affy"package19 for correction and normalization.Results:Our analysis revealed 585 upregulated and 629 downregulated differentially expressed genes in the AKI dataset,along with 586 upregulated and 948 downregulated differentially expressed genes in the trauma dataset.Concurrently,the establishment of the PPI network and subsequent topological analysis highlighted key hub genes,including CD44,CD163,TIMP metallopeptidase inhibitor 1,cytochrome b-245 beta chain,versican,membrane spanning 4-domains A4A,mitogen-activated protein kinase 14,and early growth response 1.Notably,their receiver operating characteristic curves displayed areas exceeding 75％,indicating good diagnostic performance.Moreover,our findings postulated a unique molecular mecha-nism underlying trauma-related AKI.Conclusion:This study presents an alternative strategy for the early diagnosis and treatment of trauma-related AKI,based on the identification of potential biomarkers and therapeutic targets.Additionally,this study provides theoretical references for elucidating the mechanisms of trauma-related AKI.

    Study on the preservation effects of the amputated forelimb by machine perfusion at physiological temperature

    Sheng-Feng ChenBo-Yao YangTie-Yuan ZhangXiang-Yu Song...
    114-120页
    查看更多>>摘要：Purpose:Ischemia and hypoxia are the main factors limiting limb replantation and transplantation.Static cold storage(SCS),a common preservation method for tissues and organs,can only prolong limb ischemia time to 4-6 h.The normothermic machine perfusion(NMP)is a promising method for the preservation of tissues and organs,which can extend the preservation time in vitro by providing continuous oxygen and nutrients.This study aimed to evaluate the difference in the efficacy of the 2 limb preservation methods.Methods:The 6 forelimbs from beagle dogs were divided into 2 groups.In the SCS group(n=3),the limbs were preserved in a sterile refrigerator at 4 ℃ for 24 h,and in the NMP group(n=3),the perfusate prepared with autologous blood was used for the oxygenated machine perfusion at physiological tem-perature for 24 h,and the solution was changed every 6 h.The effects of limb storage were evaluated by weight gain,perfusate biochemical analysis,enzyme-linked immunosorbent assay,and histological analysis.All statistical analyses and graphs were performed using GraphPad Prism 9.0 one-way or two-way analysis of variance.The p value of less than 0.05 was considered to indicate statistical significance.Results:In the NMP group,the weight gained percentage was 11.72％±4.06％;the hypoxia-inducible factor-1α contents showed no significant changes;the shape of muscle fibers was normal;the gap be-tween muscle fibers slightly increased,showing the intercellular distance of(30.19±2.83)pm;and the vascular α-smooth muscle actin(α-SMA)contents were lower than those in the normal blood vessels.The creatine kinase level in the perfusate of the NMP group increased from the beginning of perfusion,decreased after each perfusate change,and remained stable at the end of perfusion showing a peak level of 4097.6 U/L.The lactate dehydrogenase level of the NMP group increased near the end of perfusion and reached the peak level of 374.4 U/L.In the SCS group,the percentage of weight gain was 0.18％±0.10％,and the contents of hypoxia-inducible factor-1α increased gradually and reached the maximum level of(164.85±20.75)pg/mL at the end of the experiment.The muscle fibers lost their normal shape and the gap between muscle fibers increased,showing an intercellular distance of(41.66±5.38)pm.The con-tents of vascular α-SMA were much lower in the SCS group as compared to normal blood vessels.Conclusions:NMP caused lesser muscle damage and contained more vascular α-SMA as compared to SCS.This study demonstrated that NMP of the amputated limb with perfusate solution based on autologous blood could maintain the physiological activities of the limb for at least 24 h.

    121-124页
    查看更多>>摘要：A fracture of the acromion and coracoid processes of scapula is rarely seen in the outpatient clinic,due to the acromion's anatomical position and shape,as well as the strong ligaments and muscles that are attached to it.These fractures are caused by either direct or indirect high-energy trauma injuries to the shoulder joint,leading to severe pain and a grossly restricted range of motion.Several acromial classi-fications were reported,but this type of longitudinal plane fracture of the acromion process in our case is yet to be described in the current literature.We present a rare combination of the coracoid process and unstable acromion bony projection fractures that have not previously been noted for this type of fracture.The closest to this is Kuhn's type Ⅲ classification.A 51-year-old male presented to our emergency department complaining of the right shoulder pain and difficulty raising his arm following a 2-wheeler accident.The patient was managed by open reduction and internal fixation with 3 cannulated cancellous screws fixation and progressed well with no postoperative complications.He was asymptomatic post-operatively and regained full range of motion after 4 months.
