Traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease are three distinct neurological disorders that share common pathophysiological mechanisms involving neuroinflammation. One sequela ...Traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease are three distinct neurological disorders that share common pathophysiological mechanisms involving neuroinflammation. One sequela of neuroinflammation includes the pathologic hyperphosphorylation of tau protein, an endogenous microtubule-associated protein that protects the integrity of neuronal cytoskeletons. Tau hyperphosphorylation results in protein misfolding and subsequent accumulation of tau tangles forming neurotoxic aggregates. These misfolded proteins are characteristic of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease and can lead to downstream neuroinflammatory processes, including assembly and activation of the inflammasome complex. Inflammasomes refer to a family of multimeric protein units that, upon activation, release a cascade of signaling molecules resulting in caspase-induced cell death and inflammation mediated by the release of interleukin-1β cytokine. One specific inflammasome, the NOD-like receptor protein 3, has been proposed to be a key regulator of tau phosphorylation where it has been shown that prolonged NOD-like receptor protein 3 activation acts as a causal factor in pathological tau accumulation and spreading. This review begins by describing the epidemiology and pathophysiology of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease. Next, we highlight neuroinflammation as an overriding theme and discuss the role of the NOD-like receptor protein 3 inflammasome in the formation of tau deposits and how such tauopathic entities spread throughout the brain. We then propose a novel framework linking traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease as inflammasomedependent pathologies that exist along a temporal continuum. Finally, we discuss potential therapeutic targets that may intercept this pathway and ultimately minimize long-term neurological decline.展开更多

The most common hurdles faced during spinal cord injury are failure of axonal regrowth and reconnection to target sites. These also tend to be the most challenging issues in spinal cord injury. As spinal cord injury progresses to the chronic phase, lost motor and sensory functions are not recovered. Several reasons may be attributed to the failure of recovery from chronic spinal cord injury. These include factors that inhibit axonal growth such as activated astrocytes, chondroitin sulfate proteoglycan, myelin-associated proteins, inflammatory microglia, and fibroblasts that accumulate at lesion sites. Skeletal muscle atrophy due to denervation is another chronic and detrimental spinal cord injury–specific condition. Although several intervention strategies based on multiple outlooks have been attempted for treating spinal cord injury, few approaches have been successful. To treat chronic spinal cord injury, neural cells or tissue substitutes may need to be supplied in the cavity area to enable possible axonal growth. Additionally, stimulating axonal growth activity by extrinsic factors is extremely important and essential for maintaining the remaining host neurons and transplanted neurons. This review focuses on pharmacotherapeutic approaches using small compounds and proteins to enable axonal growth in chronic spinal cord injury. This review presents some of these candidates that have shown promising outcomes in basic research(in vivo animal studies) and clinical trials: AA-NgR(310)ecto-Fc(AXER-204), fasudil, phosphatase and tensin homolog protein antagonist peptide 4, chondroitinase ABC, intracellular sigma peptide,(-)-epigallocatechin gallate, matrine, acteoside, pyrvate kinase M2, diosgenin, granulocyte-colony stimulating factor, and fampridine-sustained release. Although the current situation suggests that drug-based therapies to recover function in chronic spinal cord injury are limited, potential candidates have been identified through basic research, and these candidates may be subjects of clinical studies in the future. Moreover, cocktail therapy comprising drugs with varied underlying mechanisms may be effective in treating the refractory status of chronic spinal cord injury.展开更多

文摘BACKGROUND Eosinophilic gastrointestinal(GI)disease(EGID)beyond eosinophilic esophagitis is not commonly reported in the developing world.AIM To estimate the prevalence of EGID in a selected group of pediatric patients suffering from non-functional chronic abdominal pain(CAP).METHODS A retrospective analysis was conducted on case records of children with CAP.Those exhibiting clinical or laboratory alarming features underwent endoscopic evaluation.Histopathology reports from upper GI endoscopy and ileo-colonoscopy determined the diagnosis of EGID.Subsequent analyses included clinical presentations,presence of atopy in the children or family,hemoglobin,albumin,serum immunoglobulin E(IgE),fecal calprotectin levels,endoscopic appearances,treatment methods,and outcomes.RESULTS A total of 368 children with organic CAP were subjected to endoscopic evaluation.Among them,19(5.2%)patients with CAP were diagnosed with EGID.The median age of the children was 11.1 years(interquartile range=8.4-14.4).The estimated prevalence of EGID in children with organic CAP was 520/10000 children over 5 years.Periumbilical pain was the most common site(63%).Family history of atopy,peripheral blood eosinophilia,and elevated serum IgE were the three parameters significantly associated with EGID.Clinical remission was obtained in all children at 6 months.The 47%had microscopic remission and maintained remission until a 1-year follow-up.The 53%had a fluctuating clinical course after 6 months.CONCLUSION EGID beyond the esophagus is not an uncommon entity among the children of India.It can contribute significantly to the etiology of pediatric CAP.
文摘Image processing plays a vital role in various fields such as autonomous systems,healthcare,and cataloging,especially when integrated with deep learning(DL).It is crucial in medical diagnostics,including the early detection of diseases like chronic obstructive pulmonary disease(COPD),which claimed 3.2 million lives in 2015.COPD,a life-threatening condition often caused by prolonged exposure to lung irritants and smoking,progresses through stages.Early diagnosis through image processing can significantly improve survival rates.COPD encompasses chronic bronchitis(CB)and emphysema;CB particularly increases in smokers and generally affects individuals between 50 and 70 years old.It damages the lungs’air sacs,reducing oxygen transport and causing symptoms like coughing and shortness of breath.Treatments such as beta-agonists and inhaled steroids are used to manage symptoms and prolong lung function.Moreover,COVID-19 poses an additional risk to individuals with CB due to its impact on the respiratory system.The proposed system utilizes convolutional neural networks(CNN)to diagnose CB.In this system,CNN extracts essential and significant features from X-ray modalities,which are then fed into the neural network.The network undergoes training to recognize patterns and make accurate predictions based on the learned features.By leveraging DL techniques,the system aims to enhance the precision and reliability of CB detection.Our research specifically focuses on a subset of 189 lung disease images,carefully selected for model evaluation.To further refine the training process,various data augmentation and noise removal techniques are implemented.These techniques significantly enhance the quality of the training data,improving the model’s robustness and generalizability.As a result,the diagnostic accuracy has improved from 98.6%to 99.2%.This advancement not only validates the efficacy of our proposed model but also represents a significant improvement over existing literature.It highlights the potential of CNN-based approaches in transforming medical diagnostics through refined image analysis,learning capabilities,and automated feature extraction.

文摘BACKGROUND Low serum albumin levels are established predictors of adverse outcomes in various cardiovascular conditions.However,the role of serum albumin in mortality among elderly patients with chronic aortic regurgitation(AR)has not been thoroughly investigated.This study aims to assess the relationship between serum albumin levels and mortality in this specific patient population.METHODS Our analysis included 873 elderly AR patients from the China Valvular Heart Disease study,with baseline serum albumin measured at enrollment.Mortality outcomes were monitored for two years post-enrollment,employing a Cox proportional hazards model with a two-piecewise Cox proportional hazards framework to investigate the nonlinear relationship between serum albumin levels and all-cause mortality.RESULTS During the 2-year follow-up period,we observed 63 all-cause deaths.The association between serum albumin levels and all-cause mortality displayed an approximating L-shaped curve,indicating a mortality threshold at 35 g/L.For serum albumin levels below 35 g/L,each 1 g/L decrease was associated with a 25%higher risk of all-cause mortality(HR=1.25,95%CI:1.07–1.45).In contrast,no significant change in mortality risk was observed when serum albumin levels were greater than or equal to 35 g/L.Moreover,when serum albumin is classified as hypoproteinemia(serum albumin<35 g/L),the higher risks of all-cause death were observed in hypoproteinemic patients(HR=2.93,95%CI:1.50–5.74).More importantly,the association between serum albumin and death was significantly stronger in overweight/obese patients(≥24 kg/m^(2)vs.<24 kg/m^(2),Pinteraction=0.006).CONCLUSIONS In elderly patients with AR,serum albumin levels showed an approximating L-shaped relationship with all-cause death,with thresholds of 35 g/L.Body mass index was significant effect modifiers of the association.These results suggest that serum albumin,as an inexpensive and readily available biochemical marker,may further improve the stratified risk of mortality in older AR patients.

文摘BACKGROUND The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined.METHODS All CTO vessels treated with successful anatomical PCI in patients from PANDA Ⅲ trial were retrospectively measured for postPCI QFR.The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs,composite of target vessel-related cardiac death,target vessel-related myocardial infarction,and ischemia-driven target vessel revascularization).Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs,and all vessels were stratified by this optimal cutoff value.Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI.RESULTS Among 428 CTO vessels treated with PCI,353 vessels (82.5%) were analyzable for post-PCI QFR.31 VOCEs (8.7%) occurred at 2 years.Mean value of post-PCI QFR was 0.92±0.13.Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91.The incidence of 2-year VOCEs in the vessel with post-PCI QFR<0.91 (n=91) was significantly higher compared with the vessels with post-PCI QFR≥0.91 (n=262)(22.0%vs.4.2%,HR=4.98,95%CI:2.32–10.70).CONCLUSIONS Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO.Achieving functionally optimal PCI results (post-PCI QFR value≥0.91) tends to get better prognosis for patients with CTO lesions.

文摘Chronic pain after spine surgery(CPSS)is a complex disorder characterized by multifactorial pathogenesis that occurs in 8%–40%of patients undergoing lumbar spine surgery.We aimed to develop a rat model that mimics clinical CPSS conditions by taking two sequential surgical procedures.Step 1:A plastic rod was inserted into the left L5 intervertebral foramen to produce a steady compression on the dorsal root ganglion(DRG)and the spinal nerve,a common cause of low back pain(LBP).Step 2:The rod was removed after 7 days when rats exhibited mechanical and heat hypersensitivity in the ipsilateral hindpaw,followed by a full L5 laminectomy to mimic spine decompression surgery in LBP patients.The retention of the rod induced a prolonged LBP-like behavior but was quickly resolved after rod removal without laminectomy.However,rats that received laminectomy after rod removal developed heightened mechanical and heat sensitivity in the hindpaw,impaired gait,and reduced spontaneous exploration activity,indicating CPSS.Patch clamp recording revealed a significant augmentation in the intrinsic excitability of smalldiameter DRG neurons in CPSS rats.Administration of Dermorphin[D-Arg2,Lys4](1–4)amide(DALDA,5mg/kg,i.p.),a peripherally acting mu-opioid receptor(MOR)-preferred agonist,attenuated pain hypersensitivity,capsaicin-induced[Ca^(2+)]i rising and the increased intrinsic excitability of DRG neurons from CPSS rats.Our findings suggest that this new model,which mirrors the nature of CPSS developed in patients,may be useful for future studies of the underlying mechanisms.
文摘This review aims to comprehensively discuss the application status,theoretical basis,practical methods,empirical research,challenges,and future development direction of patient journey map in chronic disease management.By integrating current advances in academia and practice,this paper suggests that the patient journey map is an effective tool that can significantly improve the efficiency and quality of care delivery,increase patient engagement,and optimize the allocation of health care resources in chronic disease management.Nevertheless,the popularization and deepening application of patient journey map also faces a series of problems,such as difficulties in data collection,challenges in technology integration,and resistance to organizational change.In the future,with the progress of technology and policy support,the patient journey map is expected to become a key force to promote the innovation of chronic disease management model.Through in-depth analysis of these problems and opportunities,this paper provides valuable reference and enlightenment for healthcare providers,policy makers and relevant stakeholders.

文摘Chronic atrophic gastritis includes two main types:autoimmune gastritis(AIG),also known as type A gastritis,and non-AIG.AIG primarily affects the fundus and body of the stomach and is characterized by atrophy of the gastric body mucosa[1,2].The non-AIG category includes type B gastritis,where the lesions mainly occur in the gastric antrum,as well as chronic superficial gastritis,an early stage of stomach disorders.The diagnosis of AIG versus non-AIG heavily relies on gastroscopy,a procedure known for its risks and inconvenience.Therefore,identifying biomarkers that can distinguish between AIG and non-AIG is crucial.However,there are currently no reports on small-molecule biomarkers for distinguishing between AIG and non-AIG.In this study,we investigated the serum metabolomics of AIG and non-AIG patients using ultra-high-performance liquid chromatography-mass spectrometry(UHPLC/MS),and compared their metabolic profile differences.In total 46 differential metabolites were identified,and three of which(L-glutamic acid,anthranilate,and deoxyadenosine)were linked to the regulation of gastric biosynthetic genes.
文摘Aging is an inevitable process that is usually measured by chronological age,with people aged 65 and over being defined as"older individuals".There is disagreement in the current scientific literature regarding the best methods to estimate glomerular filtration rate(eGFR)in older adults.Several studies suggest the use of an age-adjusted definition to improve accuracy and avoid overdiagnosis.In contrast,some researchers argue that such changes could complicate the classification of chronic kidney disease(CKD).Several formulas,including the Modification of Diet in Renal Disease,CKD-Epidemiology Collaboration,and Cockcroft-Gault equations,are used to estimate eGFR.However,each of these formulas has significant limitations when applied to older adults,primarily due to sarcopenia and malnutrition,which greatly affect both muscle mass and creatinine levels.Alternative formulas,such as the Berlin Initiative Study and the Full Age Spectrum equations,provide more accurate estimates of values for older adults by accounting for age-related physiological changes.In frail older adults,the use of cystatin C leads to better eGFR calculations to assess renal function.Accurate eGFR measurements improve the health of older patients by enabling better medication dosing.A thorough approach that includes multiple calibrated diagnostic methods and a detailed geriatric assessment is necessary for the effective management of kidney disease and other age-related conditions in older adults.
文摘To evaluate the subchronic and chronic toxicity of Fuyanxiao capsules,Sprague-Dawley(SD)rats were used in toxicity studies.In the subchronic toxicity study,50 female rats were randomly divided into a high-dose group(5.4g/kg/day)and a control group,with 15 rats in each,and medium(2.7g/kg/day)and low(1.35g/kg/day)dose groups,with 10 rats in each.The test substance was administered orally(mixed with feed,twice daily)for 90 consecutive days.In the chronic toxicity study,40 female rats were randomly divided into high,medium,and low dose groups and a control group,with 10 rats in each.The test substance was administered orally in the same manner for 180 consecutive days.Clinical signs,body weight,and food consumption were observed and recorded daily.At the end of the terminal phase(the first 10 rats from each group,1 day after the last dose)and the recovery phase(the last 5 rats from the control group and the high-dose group,observed for an additional 28 days after the last dose),blood and urine samples,as well as organs,were collected.Organ coefficients were calculated,and various hematological and urinary indicators were detected,followed by pathological analysis.The results showed that there were no significant differences in body weight,food consumption,or organ coefficients between any of the dose groups and the control group in both subchronic and chronic toxicity studies(P>0.05).Histopathological examination revealed no lesions,suggesting no tissue or organ damage in any of the dose groups.The rats exhibited good mental status,and hematological and urinary physiological indicators were within normal ranges,indicating stable liver and kidney function,hematopoietic system of the bone marrow,and internal environment in all dose groups.Therefore,Fuyanxiao capsule has no obvious subchronic or chronic toxicity in SD rats,and it is safe and reliable to use at reasonable dosage in clinical practice.
文摘Traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease are three distinct neurological disorders that share common pathophysiological mechanisms involving neuroinflammation. One sequela of neuroinflammation includes the pathologic hyperphosphorylation of tau protein, an endogenous microtubule-associated protein that protects the integrity of neuronal cytoskeletons. Tau hyperphosphorylation results in protein misfolding and subsequent accumulation of tau tangles forming neurotoxic aggregates. These misfolded proteins are characteristic of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease and can lead to downstream neuroinflammatory processes, including assembly and activation of the inflammasome complex. Inflammasomes refer to a family of multimeric protein units that, upon activation, release a cascade of signaling molecules resulting in caspase-induced cell death and inflammation mediated by the release of interleukin-1β cytokine. One specific inflammasome, the NOD-like receptor protein 3, has been proposed to be a key regulator of tau phosphorylation where it has been shown that prolonged NOD-like receptor protein 3 activation acts as a causal factor in pathological tau accumulation and spreading. This review begins by describing the epidemiology and pathophysiology of traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease. Next, we highlight neuroinflammation as an overriding theme and discuss the role of the NOD-like receptor protein 3 inflammasome in the formation of tau deposits and how such tauopathic entities spread throughout the brain. We then propose a novel framework linking traumatic brain injury, chronic traumatic encephalopathy, and Alzheimer's disease as inflammasomedependent pathologies that exist along a temporal continuum. Finally, we discuss potential therapeutic targets that may intercept this pathway and ultimately minimize long-term neurological decline.
文摘Spinal cord injury is an intractable traumatic injury. The most common hurdles faced during spinal cord injury are failure of axonal regrowth and reconnection to target sites. These also tend to be the most challenging issues in spinal cord injury. As spinal cord injury progresses to the chronic phase, lost motor and sensory functions are not recovered. Several reasons may be attributed to the failure of recovery from chronic spinal cord injury. These include factors that inhibit axonal growth such as activated astrocytes, chondroitin sulfate proteoglycan, myelin-associated proteins, inflammatory microglia, and fibroblasts that accumulate at lesion sites. Skeletal muscle atrophy due to denervation is another chronic and detrimental spinal cord injury–specific condition. Although several intervention strategies based on multiple outlooks have been attempted for treating spinal cord injury, few approaches have been successful. To treat chronic spinal cord injury, neural cells or tissue substitutes may need to be supplied in the cavity area to enable possible axonal growth. Additionally, stimulating axonal growth activity by extrinsic factors is extremely important and essential for maintaining the remaining host neurons and transplanted neurons. This review focuses on pharmacotherapeutic approaches using small compounds and proteins to enable axonal growth in chronic spinal cord injury. This review presents some of these candidates that have shown promising outcomes in basic research(in vivo animal studies) and clinical trials: AA-NgR(310)ecto-Fc(AXER-204), fasudil, phosphatase and tensin homolog protein antagonist peptide 4, chondroitinase ABC, intracellular sigma peptide,(-)-epigallocatechin gallate, matrine, acteoside, pyrvate kinase M2, diosgenin, granulocyte-colony stimulating factor, and fampridine-sustained release. Although the current situation suggests that drug-based therapies to recover function in chronic spinal cord injury are limited, potential candidates have been identified through basic research, and these candidates may be subjects of clinical studies in the future. Moreover, cocktail therapy comprising drugs with varied underlying mechanisms may be effective in treating the refractory status of chronic spinal cord injury.

文摘BACKGROUND Addressing the growing challenge of hospitalizing chronic multimorbid patients,this study examines the strain these conditions impose on healthcare systems at a local level,focusing on a pilot program.Chronic diseases and complex patients require comprehensive management strategies to reduce healthcare burdens and improve patient outcomes.If proven effective,this pilot model has the potential to be replicated in other healthcare settings to enhance the management of chronic multimorbid patients.AIM To evaluate the effectiveness of the high complexity unit(HCU)in managing chronic multimorbid patients through a multidisciplinary care model and to compare it with standard hospital care.METHODS The study employed a descriptive longitudinal approach,analyzing data from the Basic Minimum Data Set(BMDS)to compare hospitalization variables among the HCU,the Internal Medicine Service,and other services at Antequera Hospital throughout 2022.The HCU,designed for patients with complex chronic conditions,integrates a patient-centered model emphasizing multidisciplinary care and continuity post-discharge.RESULTS The study employed a descriptive longitudinal approach,analyzing data from the BMDS to compare hospitalization variables among the HCU,the Internal Medicine Service,and other services at Antequera Hospital throughout 2022.The HCU,designed for patients with complex chronic conditions,integrates a patient-centered model emphasizing multidisciplinary care and continuity post-discharge.CONCLUSION This study demonstrates the effectiveness of the HCU in managing patients with complex chronic diseases through a multidisciplinary approach.The coordinated care provided by the HCU results in improved patient outcomes,reduced unnecessary hospitalizations,and better management of patient complexity.The superiority of the HCU compared to standard care is evident in key outcomes such as fewer readmissions and higher patient satisfaction,reinforcing its value as a model of care to be replicated.
文摘BACKGROUND Middle meningeal artery embolization(MMAE)is emerging as a promising treatment for chronic subdural hematoma(CSDH),serving both as an adjunct to surgery and as a primary therapeutic option depending on patient presentation.Due to its low recurrence rate and minimal complications,MMAE has gained increasing acceptance among clinicians in recent years.This report presents a case of diplopia following MMAE due to the presence of a potential anastomotic artery,aiming to enhance awareness of this complication.CASE SUMMARY A 60-year-old male patient presented with a headache following head trauma,and cranial computed tomography revealed a left-sided CSDH.The patient underwent left MMAE;however,polyvinyl alcohol particles inadvertently flowed into the lacrimal artery through an anastomotic artery,resulting in diplopia due to impaired abduction of the left eye.The diplopia resolved by postoperative day 40.The patient’s headache resolved by postoperative day 7,and the hematoma completely resolved by postoperative day 108.CONCLUSION Potential anastomotic arteries in the middle meningeal artery(MMA)can lead to serious complications.Superselective angiography of the MMA or its branches prior to embolization is essential.Performing embolization distal to potential anastomotic sites can reduce risks,and the presence of an anastomosis may warrant coil embolization or termination of the procedure.

文摘BACKGROUND Anxiety and depression are prevalent among patients with chronic heart failure(CHF)and can adversely contribute to treatment adherence and clinical outcomes.Poor fluid restriction adherence is a widespread challenge in the management of CHF.To effectively manage disease progression and alleviate symptoms,it is crucial to identify key influencing factors to facilitate the implementation of targeted interventions.AIM To investigate the status of anxiety and depression among patients with CHF and determine the factors contributing to poor fluid restriction adherence.METHODS Three hundred CHF patients seeking medical treatment at The First Hospital of Hunan University of Traditional Chinese Medicine between June 2021 and June 2023 were included in the study.Questionnaires,including the Psychosomatic Symptom Scale,Self-Rating Anxiety Scale,Self-Rating Depression Scale,and Fluid Restriction Adherence Questionnaire were administered to patients.Based on their anxiety and depression scores,patients were categorized into anxiety/depression and non-anxiety/depression groups,as well as fluid restriction adherence and fluid restriction non-adherence groups.General patient data were collected,and univariate and logistic regression analyses were conducted to determine the occurrence of depression and anxiety.Logistic regression analysis was used to identify independent factors influencing fluid restriction adherence.RESULTS Statistically significant differences in age,New York Heart Association(NYHA)grading,marital status,educational attainment,and family support were observed between depressed and non-depressed CHF patients(P<0.05).Age,NYHA grading,marital status,educational attainment,and family support were identified as factors influencing the development of depression.The anxiety and non-anxiety groups differed statistically in terms of gender,age,NYHA grading,smoking history,alcohol consumption history,monthly income,educational attainment,and family support(P<0.05).Gender,smoking,alcohol consumption,monthly income,and educational attainment affected anxiety in these patients.The fluid restriction adherence rate was 28.0%,and thirst sensation,anxiety,and depression were identified as independent influencing factors.CONCLUSION CHF patients are susceptible to anxiety and depression,with multiple associated influencing factors.Moreover,anxiety and depression are independent factors that can influence fluid restriction adherence in these patients.

文摘Lingguizhugan Decoction(LGZG)demonstrates significant efficacy in treating various cardiovascular diseases clinically,yet its precise mechanism of action remains elusive.This study aimed to elucidate the potential mechanisms and effects of LGZG on isoproterenol(ISO)continuous stimulation-induced chronic heart failure(CHF)in mice,providing direct experimental evidence for further clinical applications.In vivo,continuous ISO infusion was administered to mice,and ventricular myocytes were utilized to explore LGZG's potential mechanism of action on theβ1-adrenergic receptor(β1-AR)/Gs/G protein-coupled receptor kinases(GRKs)/β-arrestin signaling deflection system in the heart.The findings reveal that LGZG significantly reduced the messenger ribonucleic acid(mRNA)expression of hypertrophy-related biomarkers[atrial natriuretic peptide(ANP)and B-type natriuretic peptide(BNP)]and improved cardiac remodeling and left ventricular diastolic function in mice with ISO-induced CHF.Furthermore,LGZG inhibited the overactivation of Gs/cyclic adenosine monophosphate(c AMP)/protein kinase A(PKA)signaling and downregulated the downstream transcriptional activity of c AMP-response element binding protein(CREB)and the expression of the coactivator CBP/P300.Notably,LGZG downregulated the expression ofβ-arrestin1 and GRK 2/3/5 while upregulating the expression ofβ1-AR andβ-arrestin2.These results suggest that LGZG inhibits Gs/c AMP/PKA signaling andβ-arrestin/GRK-mediated desensitization and internalization ofβ1-AR,potentially exerting cardioprotective effects through the synergistic regulation of theβ1-AR/Gs/GRKs/β-arrestin signaling deflection system via multiple pathways.

文摘BACKGROUND Nocardiosis is a rare bacterial infection with unclear epidemiology,pathogenesis,and characteristics.Its clinical manifestations are diverse and nonspecific,making diagnosis prone to errors,including misdiagnosis and missed diagnosis.Additionally,this disease is difficult to treat,often requiring months or even years of antibacterial therapy,and can be fatal in patients with underlying conditions.CASE SUMMARY A 93-year-old male patient with chronic renal insufficiency sustained a skin injury at the tip of his right thumb.As a result of an initial misdiagnosis and inadequate treatment,the infection progressed,resulting in multiple rashes on his right upper limb.Local incision and drainage of pus,combined with oral antibiotics administered at a different hospital,yielded no significant improvement.Upon hospitalization,the patient’s immune function was assessed,and further local incision and drainage were performed.Cultures of the pus identified Nocardia brasiliensis.Treatment involved intravenous infusion of piperacillin-tazobactam sodium and oral administration of sulfamethoxazole-trimethoprim,leading to the patient’s recovery.After discharge,the patient continued to take sulfamethoxazole tablets for 6 months,with complete healing of the skin lesions and no recurrence.CONCLUSION Nocardiosis should be considered in patients with underlying conditions and compromised immunity.Prompt and accurate diagnosis is crucial.
