Importantly, NAFLD is one of its most dangerous complications because it can lead to severe liver pathologies, including fibrosis, cirrhosis and hepatic cellular carcinoma. Given the increasing worldwide prevalence of obesity, NAFLD has become the most common cause of chronic liver disease and therefore is a major global health problem. Currently, NAFLD is predominantly regarded as a hepatic manifestation of Met S. However, accumulating evidence indicates that the effects of NAFLD extend beyond the liver and are negatively associated with a range of chronic diseases, most notably cardiovascular disease(CVD), diabetes mellitus type 2(T2DM) and chronic kidney disease(CKD). It is becoming increasingly clear that these diseases are the result of the same underlying pathophysiological processes associated with Met S, such as insulin resistance, chronic systemic inflammation and dyslipidemia. As a result, they have been shown to be independent reciprocal risk factors. In addition, recent data have shown that NAFLD actively contributes to aggravation of the pathophysiology of CVD, T2 DM, and CKD, as well as several other pathologies. Thus, NAFLD is a direct cause of many chronic diseases associated with MetS, and better detection and treatment of fatty liver disease is therefore urgently needed. As non-invasive screening methods for liver disease become increasingly available, detection and treatment of NAFLD in patients with MetS should therefore be considered by both(sub-) specialists and primary care physicians.展开更多

The main mutation is the actin alpha 2(ACTA2) gene p.R179 H. In this paper, we report a Chinese MSMDS patient and systematically review the previous literature.CASE SUMMARY Here, we report a 9.6-month-old Chinese girl who was diagnosed with MSMDS based on her history and symptoms, such as recurrent cough, wheezing, and complications with congenital fixed dilated pupils. Chest high-resolution computed tomography revealed inhomogeneous lung transparency, obvious exudative lesions, and some lung fissures that were markedly thickened. Cranial magnetic resonance imaging excluded bleeding and infarction but showed abnormal signals in the centrum ovale majus and bilateral periventricular regions. Echocardiography only showed patent foramen ovale, and no patent ductus arteriosus, pulmonary artery dilatation, or pulmonary hypertension was found. Bronchoscopy indicated moderate bronchial malacia. These examinations in conjunction with the typical eye abnormality suggested a diagnosis of MSMDS, and sequencing of exon 6 of the ACTA2 gene demonstrated the heterozygous mutation c.536 G>A, p.R179 H. However, her parents' gene analyses were normal.CONCLUSION MSMDS is a rare genetic disease mainly caused by the mutation of the ACTA2 gene p.R179 H. Early genetic diagnosis should be performed for children presenting with congenital fixed dilated pupils and patent ductus arteriosus.During the process of diagnosis and treatment, clinicians should be on high alert for cerebrovascular, cardiovascular, and pulmonary complications.展开更多

The relationship between Covid-19 infection during pregnancy and neonatal neurodevelopmental outcome, if any, is unclear necessitating a follow-up study in this aspect. Methods: 16 babies with MIS-N, born to symptomatic Covid antibody positive mothers were enrolled. Demographic profile, treatment details and biochemical parameters were analyzed with neurodevelopmental follow-up. Results: 25% mothers received 2 doses of Covid vaccine;50% had oligohydramnios and 75% received antenatal steroids. 87.5% were preterm of which 62.5% required surfactant with ventilator support and 75% required ionotropic support. Significant association was found between the antibody level and D-dimer levels with the ferritin and LDH levels of the baby (p 0.05);gestational age with LDH and D-dimer levels (p 0.05) and Covid antibody level of the baby vs the duration of ventilator requirement (P-value-0.0009). D-dimer values of babies were positively associated with both maternal antibody and D-dimer levels. Neurodevelopmental follow-up done at 6 months of corrected gestational age showed 37.5% were normal, 37.5% hypertonic and 25% hypotonic. HINE score was below 60 in 62.5%. Development assessment using Bayley-III showed a delay in the motor domain (62.5%), cognitive domain (56.25%) and language domain (62.5%). Conclusion: Neurodevelopmental problems occur in babies born to Covid positive mothers and should be stratified as “high risk”. Anticipatory guidance to prospective mothers for preterm care should be given. Covid antibody titre and D-dimer levels may help to predict the NICU stay, ventilator requirement and the adverse neurodevelopmental outcomes in these babies.展开更多

This method and the one reported previously constitute a simple and universal theory for the computer-plotting of the equilibrium phase diagrams of a multisystem—sign function matrix (SFM) discrimination method. Its main steps are: determining the stable univariant scheme according to the derivative (or difference) of AIG m ; grouping the univariant curves by comparisons of the mutual relations among them; determining the existing intervals of the variables for the stable curves by comparisons of coordinate values of the curves about the invariant point; determining the stabilities of invariant points by comparisons of relations between the common curves and the invariant points. This method is suitable for any kind of phase diagram of closed or open systems in a phase diagram “space” with either 2 or more than 2 dimensions.展开更多

文摘This editorial takes a deeper look at the insights provided by Soresi and Giannitrapani,which examined the therapeutic potential of glucagon-like peptide-1 receptor agonists(GLP-1RAs)for metabolic dysfunction-associated fatty liver disease.We provide supplementary insights to their research,highlighting the broader systemic implications of GLP-1RAs,synthesizing the current understanding of their mechanisms and the trajectory of research in this field.GLP-1RAs are revolutionizing the treatment of type 2 diabetes mellitus and beyond.Beyond glycemic control,GLP-1RAs demonstrate cardiovascular and renal protective effects,offering potential in managing diabetic kidney disease alongside renin–angiotensin–aldosterone system inhibitors.Their role in bone metabolism hints at benefits for diabetic osteoporosis,while the neuroprotective properties of GLP-1RAs show promise in Alzheimer's disease treatment by modulating neuronal insulin signaling.Additionally,they improve hormonal and metabolic profiles in polycystic ovary syndrome.This editorial highlights the multifaceted mechanisms of GLP-1RAs,emphasizing the need for ongoing research to fully realize their therapeutic potential across a range of multisystemic diseases.
文摘Coronavirus is an important pathogen causing disease in humans and animals.At the end of 2019,an investigation into an increase in pneumonia cases in Wuhan,Hubei Province,China,found that the cause was a new coronavirus.This disease,which spread rapidly across China and caused an outbreak worldwide,resulted in a pandemic.Although this virus has previously been referred to as 2019-nCoV,which causes coronavirus disease 2019(COVID-19),later it was named severe acute respiratory syndrome coronavirus 2.Children were usually asymptomatic and rarely severely affected.In April 2020,reports from the United Kingdom indicated that children may have Kawasaki disease or a clinical condition similar to toxic shock syndrome.This clinical picture was later defined as multisystem inflammatory syndrome in children.Since then,similarly affected children as well as cases with other cardiac complications have been reported in other parts of the world.In this review,we aimed to evaluate COVID-19 in terms of cardiac involvement by reviewing the literature.
文摘BACKGROUND Multisystem inflammatory syndrome in adults(MIS-A)is a rare but severe disease occurring several weeks after severe acute respiratory syndrome coronavirus 2 infection.It develops in adults with inflammation of different organs including the gastrointestinal tract,heart,kidneys,skin and hematopoietic system.CASE SUMMARY We present a 58-year-old Chinese man diagnosed with MIS-A.His chief complaints were fever,generalized fatigue and anorexia,accompanied with rashes on his back.Further examination showed cardiac,renal and liver injury.He had melena and gastroscopy indicated esophageal ulcer and severe esophagitis.Repeated blood and sputum culture did not show growth of bacteria or fungi.Antibiotic treatment was stopped due to unsatisfactory performance.His condition improved after prednisone and other supportive treatment.CONCLUSION Gastrointestinal involvement in MIS-A is not uncommon.Intestinal involvement predominates,and esophageal involvement is rarely reported.Esophageal ulcer with bleeding could also be a manifestation of MIS-A.
文摘The pandemic caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has been a major challenge to be faced in recent years.While adults suffered the highest morbidity and mortality rates of coronavirus disease 2019,children were thought to be exclusively asymptomatic or to present with mild conditions.However,around April 2020,there was an outbreak of a new clinical syndrome related to SARS-CoV-2 in children-multisystemic inflam-matory syndrome in children(MIS-C)-which comprises a severe and uncon-trolled hyperinflammatory response with multiorgan involvement.The Centers for Disease Control and Prevention considers a suspected case of MIS-C an individual aged<21 years presenting with fever,high inflammatory markers levels,and evidence of clinically severe illness,with multisystem(>2)organ involvement,no alternative plausible diagnoses,and positive for recent SARS-CoV-2 infection.Despite its severity,there are no definitive disease management guidelines for this condition.Conversely,the complex pathogenesis of MIS-C is still not completely understood,although it seems to rely upon immune dysregu-lation.Hence,in this study,we aim to bring together current evidence regarding the pathogenic mechanisms of MIS-C,clinical picture and management,in order to provide insights for clinical practice and implications for future research directions.
文摘Non-alcoholic fatty liver disease(NAFLD) is one of the most common comorbidities associated with overweight and metabolic syndrome(Met S). Importantly, NAFLD is one of its most dangerous complications because it can lead to severe liver pathologies, including fibrosis, cirrhosis and hepatic cellular carcinoma. Given the increasing worldwide prevalence of obesity, NAFLD has become the most common cause of chronic liver disease and therefore is a major global health problem. Currently, NAFLD is predominantly regarded as a hepatic manifestation of Met S. However, accumulating evidence indicates that the effects of NAFLD extend beyond the liver and are negatively associated with a range of chronic diseases, most notably cardiovascular disease(CVD), diabetes mellitus type 2(T2DM) and chronic kidney disease(CKD). It is becoming increasingly clear that these diseases are the result of the same underlying pathophysiological processes associated with Met S, such as insulin resistance, chronic systemic inflammation and dyslipidemia. As a result, they have been shown to be independent reciprocal risk factors. In addition, recent data have shown that NAFLD actively contributes to aggravation of the pathophysiology of CVD, T2 DM, and CKD, as well as several other pathologies. Thus, NAFLD is a direct cause of many chronic diseases associated with MetS, and better detection and treatment of fatty liver disease is therefore urgently needed. As non-invasive screening methods for liver disease become increasingly available, detection and treatment of NAFLD in patients with MetS should therefore be considered by both(sub-) specialists and primary care physicians.

文摘BACKGROUND Multisystemic smooth muscle dysfunction syndrome(MSMDS) is a rare genetic disease worldwide. The main mutation is the actin alpha 2(ACTA2) gene p.R179 H. In this paper, we report a Chinese MSMDS patient and systematically review the previous literature.CASE SUMMARY Here, we report a 9.6-month-old Chinese girl who was diagnosed with MSMDS based on her history and symptoms, such as recurrent cough, wheezing, and complications with congenital fixed dilated pupils. Chest high-resolution computed tomography revealed inhomogeneous lung transparency, obvious exudative lesions, and some lung fissures that were markedly thickened. Cranial magnetic resonance imaging excluded bleeding and infarction but showed abnormal signals in the centrum ovale majus and bilateral periventricular regions. Echocardiography only showed patent foramen ovale, and no patent ductus arteriosus, pulmonary artery dilatation, or pulmonary hypertension was found. Bronchoscopy indicated moderate bronchial malacia. These examinations in conjunction with the typical eye abnormality suggested a diagnosis of MSMDS, and sequencing of exon 6 of the ACTA2 gene demonstrated the heterozygous mutation c.536 G>A, p.R179 H. However, her parents' gene analyses were normal.CONCLUSION MSMDS is a rare genetic disease mainly caused by the mutation of the ACTA2 gene p.R179 H. Early genetic diagnosis should be performed for children presenting with congenital fixed dilated pupils and patent ductus arteriosus.During the process of diagnosis and treatment, clinicians should be on high alert for cerebrovascular, cardiovascular, and pulmonary complications.
文摘BACKGROUND Multisystem inflammatory syndrome in children(MIS-C) has emerged as a new disease associated with COVID-19 that presents in acute critically ill children with acute cardiovascular dysfunction.AIM To determine whether the age-adjusted N-terminal pro-brain natriuretic peptide(NT-proBNP) value(Z-log-NT-proBNP) is associated with severe MIS-C and myocardial dysfunction.METHODS A retrospective study was conducted which included children with MIS-C managed at our institution between April 1,2020,and February 28,2022.We divided the population into groups depending on severity based on pediatric intensive care unit(PICU) admission.We compared Z-log-NT-proBNP values across these groups and analyzed Z-log-NT-proBNP dynamics during the onemonth follow-up.RESULTS We included 17 participants [median age 3(2-9) years] and seven(41%) required PICU admission.All(100%) of these cases presented very high(Z-log > 4) levels of NT-proBNP at the time of admission compared to only 5(50%) patients with non-severe MIS-C(P = 0.025).NT-proBNP was significantly correlated with highsensitive Troponin I levels(P = 0.045),Ross modified score(P = 0.003) and left ventricle ejection fraction(P = 0.021).CONCLUSION Raised NT-proBNP,specifically very high values(Z-log-NT-proBNP > 4) could help in the early identification of MIS-C patients with myocardial dysfunction requiring inotropic support and PICU admission.
文摘Background: Pregnant women and newborns are highly susceptible to Covid-19, manifesting as multisystem inflammatory syndrome-New-born (MISC-N) in many babies born to Covid positive mothers. The relationship between Covid-19 infection during pregnancy and neonatal neurodevelopmental outcome, if any, is unclear necessitating a follow-up study in this aspect. Methods: 16 babies with MIS-N, born to symptomatic Covid antibody positive mothers were enrolled. Demographic profile, treatment details and biochemical parameters were analyzed with neurodevelopmental follow-up. Results: 25% mothers received 2 doses of Covid vaccine;50% had oligohydramnios and 75% received antenatal steroids. 87.5% were preterm of which 62.5% required surfactant with ventilator support and 75% required ionotropic support. Significant association was found between the antibody level and D-dimer levels with the ferritin and LDH levels of the baby (p 0.05);gestational age with LDH and D-dimer levels (p 0.05) and Covid antibody level of the baby vs the duration of ventilator requirement (P-value-0.0009). D-dimer values of babies were positively associated with both maternal antibody and D-dimer levels. Neurodevelopmental follow-up done at 6 months of corrected gestational age showed 37.5% were normal, 37.5% hypertonic and 25% hypotonic. HINE score was below 60 in 62.5%. Development assessment using Bayley-III showed a delay in the motor domain (62.5%), cognitive domain (56.25%) and language domain (62.5%). Conclusion: Neurodevelopmental problems occur in babies born to Covid positive mothers and should be stratified as “high risk”. Anticipatory guidance to prospective mothers for preterm care should be given. Covid antibody titre and D-dimer levels may help to predict the NICU stay, ventilator requirement and the adverse neurodevelopmental outcomes in these babies.
文摘Multisystem inflammatory syndrome in children(MIS-C)is a rare and severe condition that follows benign COVID-19.We report autosomal recessive deficiencies of OAS1,OAS2,or RNASEL in five unrelated children with MIS-C.The cytosolic dsRNA-sensing OAS1 and OAS2 generate 2'-5'-linked oligoadenylates(2-5A)that activate the ssRNA-degrading RNase L.

文摘Background Multisystem inflammatory syndrome in children(MIS-C),a relatively uncommon but severe pediatric complication,is associated with coronavirus disease 2019(COVID-19).A variety of treatment approaches,including intravenous immunoglobulins(IVIGs),glucocorticoids(GCs)and biologic agents,such as anakinra and infliximab,have been described for the management of COVID-19-related MIS-C.Anticoagulant therapy is also important.However,a well-developed treatment system has not been established,and many issues remain controversial.Several recently published articles related to the treatment of MIS-C have been released.Hence,in this review,we identified relevant articles published recently and summarized the treatment of MIS-C more comprehensively and systematically.Data sources We reviewed the literature on the treatment of MIS-C through 20 September 2023.The PubMed/Medline,Web of Science,EMBASE,and Cochrane Library databases were searched with the combination of the terms"multisystem inflammatory syndrome","MIS-C","PIMS-TS","therapy","treatment","drug","IVIG","GCs","intravenous immunoglobulin","corticosteroids","biological agent",and"aspirin".Results The severity of MIS-C varies,and different treatment schemes should be used according to the specific condition.Ongoing research and data collection are vital to better understand the pathophysiology and optimal management of MIS-C.Conclusions MIS-Cis a disease involving multiple systems and has great heterogeneity.With the accumulation of additional experience,we have garnered fresh insights into its treatment strategies.However,there remains a critical need for greater standardization in treatment protocols,alongside the pressing necessity for more robust and meticulously conducted studies to deepen our understanding of these protocols.
文摘Background Multisystem inflammatory syndrome in children(MIS-C)is a serious health condition that develops from and is linked to coronavirus disease 2019.MIS-C is considered a multi-organ dysfunction involving cardiac,renal,respiratory,hematologic,gastrointestinal and neurological symptoms and groups of signs and symptoms such as rash or bilateral non-purulent conjunctivitis,hypotension or shock and acute gastrointestinal problems,which require immediate therapeutic intervention to prevent the aggravation of the patient’s health condition.MIS-C is relatively new in the field of evidence-based medicine;however,there are several clinical guidelines for good clinical practice.For every disorder,the guidelines have different suggestions.Hence,based on the current status of the evidence,recommendations have been combined to form a unified guideline for therapeutic management.Methods This paper compares and evaluates the current MIS-C-specific clinical practice guidelines(namely,American Academy of Pediatrics,American College of Rheumatology,Helen DeVos Children’s Hospital Foundation,Children’s Hospital of The King’s Daughters,and the Infectious Diseases Society of America).The compiled literature was then assessed by the authors separately,and an algorithm was proposed for each disorder,taking into consideration the various guidelines proposed for the management of the disorder.Results The features of MIS-C patients are unified;this is very helpful in managing its symptoms and decreasing mortality rates.In addition,recommendations for pharmacological treatment for MIS-C symptoms are formulated after cross-comparison across five different guidelines.Conclusions This study provides a general interpretation of the results in the context of other evidence and implications for future research.It proposes a unified guideline based on the current evidence,with the best potential to maintain suitable clinical standards in the Saudi Arabian Ministry of Health.
文摘Amyotrophic lateral sclerosis(ALS)is a neuromuscular condition resulting from the progressive degeneration of motor neurons in the cortex,brainstem,and spinal cord.While the typical clinical phenotype of ALS involves both upper and lower motor neurons,human and animal studies over the years have highlighted the potential spread to other motor and non-motor regions,expanding the phenotype of ALS.Although superoxide dismutase 1(SOD1)mutations represent a minority of ALS cases,the SOD1 gene remains a milestone in ALS research as it represents the first genetic target for personalized therapies.Despite numerous single case reports or case series exhibiting extramotor symptoms in patients with ALS mutations in SOD1(SOD1-ALS),no studies have comprehensively explored the full spectrum of extramotor neurological manifestations in this subpopulation.In this narrative review,we analyze and discuss the available literature on extrapyramidal and non-motor features during SOD1-ALS.The multifaceted expression of SOD1 could deepen our understanding of the pathogenic mechanisms,pointing towards a multidisciplinary approach for affected patients in light of new therapeutic strategies for SOD1-ALS.
文摘BACKGROUND Systemic immunoinflammatory diseases can affect multiple systems and organs.They have a severe course and severe complications,causing multiple organ failure and death.Quite often these patients are required to be hospitalized in the intensive care unit(ICU).Approximately 50% of patients with multisystem inflammatory syndrome associated with coronavirus disease 2019 in children and systemic lupus erythematosus need admission to the ICU.AIM To find early predictors of death in patients with immunoinflammatory diseases who are hospitalized in the ICU.METHODS The retrospective continuous cohort study included 51 patients(23 males,28 females)with immunoinflammatory diseases,including multisystem inflammatory syndrome associated with coronavirus disease 2019(n=18),systemic rheumatic diseases(n=24),and generalized infections(n=9).The patients ranged in age from 7 months to 17 years old and were admitted to the ICU of the clinic of Saint Petersburg State Pediatric Medical University from 2007 to 2023.RESULTS Thirteen patients(25.5%)died within 39(17;62)days after ICU admission.Patients with an unfavorable outcome were significantly older and were admitted to the ICU later than patients who survived(30 days vs 7 days,P=0.013)and had a longer stay in the ICU(30 days vs 6 days,P=0.003).The main predictors of the fatal outcome were age>162 months[odds ratio(OR)=10.7;95%confidence interval(CI):2.4-47.2,P=0.0006],time to ICU admission>26 days from the disease onset(OR=12.0;95%CI:2.6-55.3,P=0.008),preceding immune suppression treatment(OR=6.2;95%CI:1.6-24.0,P=0.013),invasive mycosis during the ICU stay(OR=18.8;95%CI:1.9-184.1,P=0.0005),systemic rheumatic diseases(OR=7.2;95%CI:1.7-31.1,P=0.004),and ICU stay over 15 days(OR=19.1;95%CI:4.0-91.8,P=0.00003).Multiple regression analysis(r^(2)=0.422,P<0.000002)identified two predictors of the fatal outcomes:Systemic rheumatic diseases(P=0.015)and ICU stay over 15 days(P=0.00002).CONCLUSION Identifying patients at high risk of an unfavorable outcome is the subject of the most careful monitoring and appropriate treatment program.Avoiding ICU stays for patients with systemic rheumatic diseases,close monitoring,and preventing invasive mycosis might improve the outcome in children with systemic immunemediated diseases.
文摘Background We aimed to systematically review the clinical and laboratory features of patients with the multisystem inflam-matory syndrome in pediatrics diagnosed during the COVID-19 pandemic.Data sources A literature search in Web of Science,PubMed,Scopus,and Science Direct was made up to June 29,2020.Results Analysis of 15 articles(318 COVID-19 patients)revealed that although many patients presented with the typical multisystem inflammatory syndrome in pediatrics,Kawasaki-like features as fever(82.4%),polymorphous maculopapular exanthema(63.7%),oral mucosal changes(58.1%),conjunctival injections(56.0%),edematous extremities(40.7%),and cervical lymphadenopathy(28.5%),atypical gastrointestinal(79.4%)and neurocognitive symptoms(31.8%)were also com-mon.They had elevated serum lactic acid dehydrogenase,D-dimer,C-reactive protein,procalcitonin,interleukin-6,troponin I levels,and lymphopenia.Nearly 77.0%developed hypotension,and 68.1%went into shock,while 41.1%had acute kidney injury.Intensive care was needed in 73.7%of cases;13.2%were intubated,and 37.9%required mechanical ventilation.Intravenous immunoglobulins and steroids were given in 87.7%and 56.9%of the patients,respectively,and anticoagulants were utilized in 67.0%.Pediatric patients were discharged after a hospital stay of 6.77 days on average(95%CI 4.93-8.6).Conclusions Recognizing the typical and atypical presentation of the multisystem inflammatory syndrome in pediatric COVID-19 patients has important implications in identifying children at risk.Monitoring cardiac and renal decompensation and early interventions in patients with multisystem inflammatory syndrome is critical to prevent further morbidity.

文摘A new easy method has been presented to calculate the variable intervals corresponding to the stable univariant curves and to discriminate the stabilities of invariant points. This method and the one reported previously constitute a simple and universal theory for the computer-plotting of the equilibrium phase diagrams of a multisystem—sign function matrix (SFM) discrimination method. Its main steps are: determining the stable univariant scheme according to the derivative (or difference) of AIG m ; grouping the univariant curves by comparisons of the mutual relations among them; determining the existing intervals of the variables for the stable curves by comparisons of coordinate values of the curves about the invariant point; determining the stabilities of invariant points by comparisons of relations between the common curves and the invariant points. This method is suitable for any kind of phase diagram of closed or open systems in a phase diagram “space” with either 2 or more than 2 dimensions.
文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)-induced multisystem inflammatory syndrome in children(MIS-C)is a life-threatening illness that has been reported in the United States and Europe.It affects multiple organ systems and often requires patient admission to an intensive care unit.Although some features of MIS-C overlap with Kawasaki disease,MIS-C is more common among older children and adolescents,more often affects cardiovascular and gastrointestinal systems,and more frequently presents with elevated inflammatory markers.Rapid and complete clinical recovery is possible in nearly all patients following immunomodulation therapy.Thus far,MIS-C pathophysiology and long-term prognosis are not sufficiently clear;further studies are needed.
文摘目的评估在严重创伤急救中应用综合创伤一体化急救模式的临床效果。方法回顾性分析2022年5月-2024年5月在广东省中西医结合医院急诊科就诊的104例严重创伤患者,按照实施综合创伤一体化急救模式的时间节点,将患者分为实施前组和实施后组,每组各52例。实施前组采用常规治疗模式,实施后组采用综合创伤一体化急救模式。分别比较综合创伤一体化急救模式实施前后患者在抢救成功率、抢救时间、各种并发症的发生率、血清炎症因子的表达等方面的差异。结果综合创伤一体化急救模式实施后患者抢救成功率高于实施前(χ^(2)=15.145,P<0.05),抢救时间(t=3.879,P<0.05)、辅助检查时间(t=2.252,P<0.05)和急诊接诊到手术时间(t=2.807,P<0.05)均缩短,总并发症发生率(χ^(2)=15.592,P<0.05),包括感染(χ^(2)=4.300,P=0.038)、失血性休克(χ^(2)=6.190,P=0.013)、多器官功能障碍综合征(multiple organ dysfunction syndrome,MODS)(χ^(2)=0.153,P=0.696)发生率均低于综合创伤一体化急救模式实施前。该模式实施后,患者各种炎症因子如C反应蛋白(C-reactire protein,CRP)、降钙素原(procalcitonin,PCT)的水平在治疗后明显下降(P<0.05)。结论综合创伤一体化急救模式在严重创伤的急救中疗效显著,能够提高患者的抢救成功率,节约抢救时间,降低并发症的发生率,值得在临床急救中推广应用。
