Pulmonary hypertension represents an anomalous hemodynamic state and is characterized by an excessively high blood pressure in the pulmonary artery. To simulate the hemodynamic abnormalities in pulmonary hypertension under different causes and pathologies, we construct a localized parameter circuit model governed by nonlinear ordinary derivative equations of the human circulatory system. Thus, two special cases are considered, namely pulmonary the artery stenosis and the left ventricular diastolic dysfunction. For each case of pulmonary hypertension development, we determine the relationships between blood pressure and chamber and vessel pressure-volume. When the pulmonary hypertension is due to pulmonary artery stenosis, it appears that the right ventricular pressure increases up to 90 mm Hg, likewise the rise in pulmonary artery resistance induces direct increment in pulmonary artery pressure. However, when the pulmonary hypertension is due to left ventricular diastolic dysfunction, we note that the left atrial pressure and the pulmonary vein pressure augment, leading to the growth of the pulmonary artery blood pressure. The established results within this paper are useful for understanding the hemodynamic mechanism of particular pulmonary hypertension.展开更多

Lung transplantation (Ltx) remains the ultimate option when patients are refractory toPAH-speciffc therapy. Reverse Potts shunt (RPS) has been introduced to treat suprasystemic PAH. This studyaims to investigate the clinical outcomes of suprasystemic PAH in children. Methods Embase, Pubmed,and the Cochrane Library databases were searched for related studies that reported the clinical outcomes ofsuprasystemic PAH following RPS in children. To investigate the clinical outcomes of RPS, meta-analyses ofthe early and overall mortalities were performed. Results Nine studies were included in this study. Theestimated early mortality was 14.4% (95% CI, 7.1% to 23.1%), and the overall mortality/Ltx was 23.2% (95%CI, 14.4% to 32.9%). The estimated 1-year survival was 86.3% (95% CI, 75.9% to 88.7%). A qualitative reviewshowed that the median value of 5-year survival free from Ltx of patients undergoing RPS was 68.6% (range:65% to 92.3%). Compared to Ltx, RPS did not signiffcantly increase the early mortality (OR, 2.48, 95% CI0.75 to 8.24, p = 0.14). RPS also signiffcantly improved the New York Heart Association/World HealthOrganization functional class, reduced the BNP/NT-pro BNP levels, decreased the PAH-speciffc therapy,and increased the six-minute-walking distance. Conclusions RPS may serve as an alternative treatmentfor suprasystemic drug-refractory PAH. Further large-scale and prospective cohort studies are needed tovalidate these ffndings.展开更多

Firstly,...This study explored the therapeutic targets and molecular mechanisms of Huangqi Guizhi Decoction (HGD) in alleviatingpulmonary embolism (PE) by employing network pharmacology and molecular docking techniques. Firstly, the effective activecomponents of the Chinese herbs in HGD were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database(TCMSP), and their potential therapeutic targets were predicted using the Swiss Target Prediction platform. Subsequently, PErelatedtarget genes were obtained from the Online Mendelian Inheritance in Man (OMIM) database and GeneCards database.Then, the Wei Sheng Xin tool was used to generate a Venn diagram for identifying the common targets between the herb-relatedtargets and PE-related targets. After screening these common targets, a “drug-component-target network” and a protein-proteininteraction (PPI) network were constructed. Furthermore, Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia ofGenes and Genomes (KEGG) enrichment analysis were conducted on the intersecting targets, and molecular docking verificationwas performed using AutoDockTools and PyMol software. Finally, 20 active components were screened from Astragali Radix, 7from Cinnamomi Ramulus, 13 from Paeoniae Radix Alba, 5 from Zingiberis Rhizoma Recens, and 29 from Jujubae Fructus, witha total of 983 therapeutic targets. Among these targets, 134 were associated with PE, and protein kinase B1 (AKT1), mitogenactivatedprotein kinase 1 (MAPK1), and transformation-related protein 53 (TP53) served as the core targets. The results of GOand KEGG enrichment analyses indicated that the alleviation of PE by HGD is mainly related to pathways including immuneresponse, regulation of gene expression, atherosclerosis, and tumorigenesis. Molecular docking results showed that the keyactive components in HGD could bind to the core targets spontaneously and stably. This study revealed that HGD may alleviatesymptoms in PE patients by regulating signaling pathways, modulating platelet function to exert anticoagulant effects, andregulating the expression of anti-inflammatory genes, which provided a direction for subsequent experimental research.展开更多

METHODS: Computer retrieved CNKI, VIR CBM and other databanks and manual operations retrieved correlative literatures to find randomized con- trolled trials (RCTs) about comparison between point application or adjuvant therapy and no-point-applications for treatment of chronic ob- structive pulmonary disease in stationary phase in China. RevMan 5.0 software was used for Meta anal- ysis. RESULTS: Among 3481 cases in the inclusive 32 RCTS, 1780 cases were in the test group and 1701 cases in the control group. Meta analysis indicated: I) clinical efficacy: the groups containing point ap- plication therapy all were better than the groups ofno-point-application; 2) force vital capacity (FVC): There was no statistically significant difference be- tween the group of point application plus Western Medicine and the Western Medicine group; 3) force expiratory volume 1 (FEVl): The groups containing point application therapy were better than the no-point-application; 4) FEV1% : the groups of point application plus Western Medicine were bet- ter than the Western Medicine groups; 5) FEVl/FVC: there was a significant difference between the group of point application plus Chinese drugs and the group of Chinese drug. CONCLUSION: Point application can increase clini- cal efficacy of chronic obstructive pulmonary dis- ease in stationary phase in varying degrees, and dif- ferent combinations of point application with Chi- nese drugs or Western Medicines have incomplete same actions in improvement of pulmonary func- tion and therapeutic effect.展开更多

No changes in arterial blood gases were observed in the overall subset of patients. Transient arterial oxygenation improvement was observed in only one HPS patient, early after TIPS, but this was not sustained 4 mo later.CONCLUSION: TIPS neither improved nor worsened pulmonary gas exchange in patients with portal hypertension. This data does not support the use of TIPS as a specific treatment for HPS. However, it does reinforce the view that TIPS can be safely performed for the treatment of other complications of portal hypertension in patients with HPS.展开更多

文摘Background:Under hypoxia,exaggerated compensatory responses may lead to acute mountain sickness.The excessive vasodilatory effect of nitric oxide(NO)can lower the hypoxic pulmonary vasoconstriction(HPV)and peripheral blood pressure.While NO is catalyzed by various nitric oxide synthase(NOS)isoforms,the regulatory roles of these types in the hemodynamics of pulmonary and systemic circulation in living hypoxic animals remain unclear.Therefore,this study aims to investigate the regu-latory effects of different NOS isoforms on pulmonary and systemic circulation in hypoxic rats by employing selective NOS inhibitors and continuously monitoring hemodynamic parameters of both pulmonary and systemic circulation.Methods:Forty healthy male Sprague–Dawley(SD)rats were randomly divided into four groups:Control group(NG-nitro-D-arginine methyl ester,D-NAME),L-NAME group(non-selective NOS inhibitor,NG-nitro-L-arginine methyl ester),AG group(in-ducible NOS inhibitor group,aminoguanidine),and 7-NI group(neurological NOS in-hibitor,7-nitroindazole).Hemodynamic parameters of rats were monitored for 10 min after inhibitor administration and 5 min after induction of hypoxia[15%O2,2200 m a.sl.,582 mmHg(76.5 kPa),Xining,China]using the real-time dynamic monitoring model for pulmonary and systemic circulation hemodynamics in vivo.Serum NO concentra-tions and blood gas analysis were measured.Results:Under normoxia,mean arterial pressure and total peripheral vascular resist-ance were increased,and ascending aortic blood flow and serum NO concentration were decreased in the L-NAME and AG groups.During hypoxia,pulmonary arterial pressure and pulmonary vascular resistance were significantly increased in the L-NAME and AG groups.Conclusions:This compensatory mechanism activated by inducible NOS and en-dothelial NOS effectively counteracts the pulmonary hemodynamic changes induced by hypoxic stress.It plays a crucial role in alleviating hypoxia-induced pulmonary arte-rial hypertension.

文摘Exercise training in pulmonary arterial hypertension(PAH)has been gaining popularity with guidelines now recommending it as an important adjunct to medical therapy.Despite improvements in function and quality of life,an understanding of metabolic changes and their mechanisms remain unexplored.The objective of this study was therefore to understand the metabolic basis of exercise in a monocrotaline model of PAH.24 male Wistar rats(age:8–12 weeks and mean body weight:[262.16±24.49]gms)were assigned to one of the four groups(i.e.,Control,PAH,Exercise and PAH t Exercise).The exercise groups participated in treadmill running at 13.3 m/min,five days a week for five weeks.Demographic and clinical characteristics were monitored regularly.Following the intervention,LC-MS based metabolomics were performed on blood samples from all groups at the end of five weeks.Metabolite profiling,peak identification,alignment and isotope annotation were also performed.Statistical inference was carried out using dimensionality reducing techniques and analysis of variance.Partial-least-squares discrimination analysis and variable importance in the projection scores showed that the model was reliable,and not over lifting.The analysis demonstrated significant perturbations to lipid and amino acid metabolism,arginine and homocysteine pathways,sphingolipid(p<0.05),glycerophospholipid(p<0.05)and nucleotide metabolism in PAH.Exercise,however,was seen to restore arginine(p<0.05)and homocysteine(p<0.0001)levels which were independent effects,irrespective of PAH.Dysregulated arginine and homocysteine pathways are seen in PAH.Exercise restores these dysregulated pathways and could potentially impact severity and outcome in PAH.
文摘BACKGROUND Pulmonary arterial hypertension(PAH)is a debilitating and progressive pulmonary pathology that often leads to death.Guidelines recommend the use of palliative care(PC)early in the treatment course to ease the burden of symptoms;however,uptake remains low.AIM To evaluate barriers to PC uptake and determine its association with mortality in patients with PAH.METHODS All studies discussing PC in PAH were selected in our review and analysis.Clinical and cross-sectional studies were included.Barriers were described in a qualitative fashion.A random-effects meta-analysis was also conducted,in which the odds ratio for mortality was pooled and reported,along with 95%confidence intervals.RESULTS A total of 19 studies were included in the review.The most common barriers identified included feeling like the patients were“not sick enough”,belief that PC is only appropriate for end-of-life care,belief that it would burden family members,and general feelings of hopelessness.Physicians identified structural causes,such as a lack of funding and low levels of PC-related knowledge,as barriers to recommending PC.The meta-analysis showed no statistically significant difference in mortality across four included studies(Log odds ratio=0.89,95%confidence intervals:-3.06-1.28).Heterogeneity was high(I2=80.32%).CONCLUSION Uptake of PC in PAH is low due to patient and physician-level barriers,which can be overcome with systematic PC integration.Long-term studies are also needed to investigate the impact of PC on outcomes in PAH,as the current limited data show no significant difference.
文摘This study examines hemodynamic behavior in particular cases of pulmonary hypertension without treatment. Pulmonary hypertension represents an anomalous hemodynamic state and is characterized by an excessively high blood pressure in the pulmonary artery. To simulate the hemodynamic abnormalities in pulmonary hypertension under different causes and pathologies, we construct a localized parameter circuit model governed by nonlinear ordinary derivative equations of the human circulatory system. Thus, two special cases are considered, namely pulmonary the artery stenosis and the left ventricular diastolic dysfunction. For each case of pulmonary hypertension development, we determine the relationships between blood pressure and chamber and vessel pressure-volume. When the pulmonary hypertension is due to pulmonary artery stenosis, it appears that the right ventricular pressure increases up to 90 mm Hg, likewise the rise in pulmonary artery resistance induces direct increment in pulmonary artery pressure. However, when the pulmonary hypertension is due to left ventricular diastolic dysfunction, we note that the left atrial pressure and the pulmonary vein pressure augment, leading to the growth of the pulmonary artery blood pressure. The established results within this paper are useful for understanding the hemodynamic mechanism of particular pulmonary hypertension.

文摘Background Pulmonary arterial hypertension (PAH) is a progressive condition with a poorprognosis in children. Lung transplantation (Ltx) remains the ultimate option when patients are refractory toPAH-speciffc therapy. Reverse Potts shunt (RPS) has been introduced to treat suprasystemic PAH. This studyaims to investigate the clinical outcomes of suprasystemic PAH in children. Methods Embase, Pubmed,and the Cochrane Library databases were searched for related studies that reported the clinical outcomes ofsuprasystemic PAH following RPS in children. To investigate the clinical outcomes of RPS, meta-analyses ofthe early and overall mortalities were performed. Results Nine studies were included in this study. Theestimated early mortality was 14.4% (95% CI, 7.1% to 23.1%), and the overall mortality/Ltx was 23.2% (95%CI, 14.4% to 32.9%). The estimated 1-year survival was 86.3% (95% CI, 75.9% to 88.7%). A qualitative reviewshowed that the median value of 5-year survival free from Ltx of patients undergoing RPS was 68.6% (range:65% to 92.3%). Compared to Ltx, RPS did not signiffcantly increase the early mortality (OR, 2.48, 95% CI0.75 to 8.24, p = 0.14). RPS also signiffcantly improved the New York Heart Association/World HealthOrganization functional class, reduced the BNP/NT-pro BNP levels, decreased the PAH-speciffc therapy,and increased the six-minute-walking distance. Conclusions RPS may serve as an alternative treatmentfor suprasystemic drug-refractory PAH. Further large-scale and prospective cohort studies are needed tovalidate these ffndings.

文摘Objective Pulmonary arterial hypertension(PAH)poses a growing global health challenge,yet comprehensive epidemiological data remain limited.This study aims to assess the burden of PAH from 1990 to 2021 and project trends to 2040,addressing critical gaps in incidence,mortality,and disability-adjusted life years(DALYs)across diverse socio-demographic contexts.Methods Using data from the Global Burden of Disease(GBD)2021 study,we analyzed PAH burden across 204 countries and territories,stratified by age,sex,region,and socio-demographic index(SDI).Age-standardized rates(per 100,000 populations)for incidence(ASIR),mortality(ASMR),and DALYs(ASDR)were calculated.Future trends were projected via a Bayesian age-period-cohort(BAPC)model.Results In 2021,there were 43,251(95%uncertainty interval[UI]:34,705,52,441)global incident PAH cases(age standardized incidence rate[ASIR]:0.52).From 1990 to 2021,PAH incidence rose by 85.62%,with the steepest increase in high-middle SDI regions(average annual percentage change[AAPC]:+0.19%).Despite a 48.36%rise in deaths,the age-standardized mortality rate(ASMR)declined annually by 0.84%,reflecting improved management.Central Europe had the highest ASMR(1.06 per 100,000),while low SDI regions showed reduced ASIR(−0.31%AAPC),likely due to underdiagnosis.PAH caused 642,104 DALYs globally in 2021,with infants(<1 year)bearing the highest DALY rate.Projections indicate 75,000 annual cases by 2040,emphasizing an escalating burden.Conclusion PAH burden is increasing disproportionately in aging populations and high-middle SDI regions,while low SDI areas face underdiagnosis and healthcare disparities.Targeted interventions,equitable resource allocation,and enhanced diagnostic capacity are urgently needed to mitigate future PAH-related morbidity and mortality.

文摘Pulmonary fibrosis(PF)is a progressive,fatal fibrotic disease caused by respiratory conditions.The condition can ultimately lead to severe organ failure and mortality,and is associated with multiple risk factors.Growing evidence highlights the immune system’s role in PF,with various immune components participating in inflammatory and fibrotic processes.Different immune cells,including neutrophils,lymphocytes,and macrophages,demonstrate distinct effects on PF progression and development.Furthermore,key immune system cytokines,including the interleukin(IL)family,tumor necrosis factor(TNF)-α,interferon(IFN)-γ,transforming growth factor(TGF)-β,and connective tissue growth factor(CTGF),contribute to PF initiation and progression through independent mechanisms and mutual regulation.Currently,limited effective treatments exist for PF,with several treatments causing severe adverse reactions.Natural products,characterized by multi-target effects,holistic regulation,and low toxicity,have emerged as a research focus.This review compiles the mechanisms,therapeutic potential,and active components of various natural products.These compounds can ameliorate pulmonary inflammation,epithelial-mesenchymal transition,and collagen deposition through diverse immune mechanisms,acting at specific stages or throughout the fibrotic process,thereby supporting PF management.This review examines current scientific understanding of natural products’immunological effects in PF,which is crucial for developing future anti-PF therapeutics.

文摘This study explored the therapeutic targets and molecular mechanisms of Huangqi Guizhi Decoction (HGD) in alleviatingpulmonary embolism (PE) by employing network pharmacology and molecular docking techniques. Firstly, the effective activecomponents of the Chinese herbs in HGD were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database(TCMSP), and their potential therapeutic targets were predicted using the Swiss Target Prediction platform. Subsequently, PErelatedtarget genes were obtained from the Online Mendelian Inheritance in Man (OMIM) database and GeneCards database.Then, the Wei Sheng Xin tool was used to generate a Venn diagram for identifying the common targets between the herb-relatedtargets and PE-related targets. After screening these common targets, a “drug-component-target network” and a protein-proteininteraction (PPI) network were constructed. Furthermore, Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia ofGenes and Genomes (KEGG) enrichment analysis were conducted on the intersecting targets, and molecular docking verificationwas performed using AutoDockTools and PyMol software. Finally, 20 active components were screened from Astragali Radix, 7from Cinnamomi Ramulus, 13 from Paeoniae Radix Alba, 5 from Zingiberis Rhizoma Recens, and 29 from Jujubae Fructus, witha total of 983 therapeutic targets. Among these targets, 134 were associated with PE, and protein kinase B1 (AKT1), mitogenactivatedprotein kinase 1 (MAPK1), and transformation-related protein 53 (TP53) served as the core targets. The results of GOand KEGG enrichment analyses indicated that the alleviation of PE by HGD is mainly related to pathways including immuneresponse, regulation of gene expression, atherosclerosis, and tumorigenesis. Molecular docking results showed that the keyactive components in HGD could bind to the core targets spontaneously and stably. This study revealed that HGD may alleviatesymptoms in PE patients by regulating signaling pathways, modulating platelet function to exert anticoagulant effects, andregulating the expression of anti-inflammatory genes, which provided a direction for subsequent experimental research.

文摘Chronic obstructive pulmonary disease(COPD)is one of the leading causes of death and disability worldwide.Its complex etiology involves factors such as smoking,air pollution,genetic susceptibility,and social environment.With the accelerating global aging population and urbanization,the incidence and burden of COPD continue to rise.Current treatment strategies for COPD are relatively conservative,primarily focusing on bronchodilators,inhaled corticosteroids,and long-term oxygen therapy.Although these approaches can alleviate symptoms and slow disease progression to some ex-tent,they fail to effectively target the underlying mechanisms of the disease,leaving an unmet clinical need for more-effective therapies.This highlights the urgency of de-veloping innovative drugs that are both safe and efficacious to address the challenges in COPD treatment.As a traditional Chinese medicine with a long history,Colla corii asini has garnered significant attention for its diverse pharmacological effects and fa-vorable safety profile.Research has shown that Colla corii asini possesses multiple bio-logical activities,including hematopoiesis,nourishing the lungs,enhancing immunity,anti-infection,antiaging,antitumor,and antifatigue effects.Moreover,it has demon-strated potential in regulating oxidative stress,immune imbalance,and inflammatory responses.Recent evidence suggests that Colla corii asini may play a protective role in lung function through multitarget and multipathway mechanisms.Based on previ-ous research findings,this paper explores the potential therapeutic value of Colla corii asini in COPD treatment by addressing the current clinical management challenges and identifying potential therapeutic targets.It also integrates the pharmacological effects of Colla corii asini into a broader treatment context,providing new perspec-tives for comprehensive COPD management and laying the theoretical foundation for its modernization and innovative application.
文摘OBJECTIVE: To evaluate clinical efficacy of point application or adjuvant therapy on chronic obstruc- tive pulmonary disease in stationary phase and ef- fects on pulmonary functions. METHODS: Computer retrieved CNKI, VIR CBM and other databanks and manual operations retrieved correlative literatures to find randomized con- trolled trials (RCTs) about comparison between point application or adjuvant therapy and no-point-applications for treatment of chronic ob- structive pulmonary disease in stationary phase in China. RevMan 5.0 software was used for Meta anal- ysis. RESULTS: Among 3481 cases in the inclusive 32 RCTS, 1780 cases were in the test group and 1701 cases in the control group. Meta analysis indicated: I) clinical efficacy: the groups containing point ap- plication therapy all were better than the groups ofno-point-application; 2) force vital capacity (FVC): There was no statistically significant difference be- tween the group of point application plus Western Medicine and the Western Medicine group; 3) force expiratory volume 1 (FEVl): The groups containing point application therapy were better than the no-point-application; 4) FEV1% : the groups of point application plus Western Medicine were bet- ter than the Western Medicine groups; 5) FEVl/FVC: there was a significant difference between the group of point application plus Chinese drugs and the group of Chinese drug. CONCLUSION: Point application can increase clini- cal efficacy of chronic obstructive pulmonary dis- ease in stationary phase in varying degrees, and dif- ferent combinations of point application with Chi- nese drugs or Western Medicines have incomplete same actions in improvement of pulmonary func- tion and therapeutic effect.

文摘AIM: To assess the impact of transjugular intrahepatic portosystemic shunt (TIPS) on pulmonary gas exchange and to evaluate the use of TIPS for the treatment of hepatopulmonary syndrome (HPS).METHODS: Seven patients, three of them with advanced HPS, in whom detailed pulmonary function tests were performed before and after TIPS placementat the University of Alabama Hospital and at the Hospital Clinic, Barcelona, were considered.RESULTS: TIPS patency was confirmed by hemodynamic evaluation. No changes in arterial blood gases were observed in the overall subset of patients. Transient arterial oxygenation improvement was observed in only one HPS patient, early after TIPS, but this was not sustained 4 mo later.CONCLUSION: TIPS neither improved nor worsened pulmonary gas exchange in patients with portal hypertension. This data does not support the use of TIPS as a specific treatment for HPS. However, it does reinforce the view that TIPS can be safely performed for the treatment of other complications of portal hypertension in patients with HPS.
