Methods: Data were analyzed from 74 patients with severe pneumonia undergoing respiratory support at our hospital between May 2024 and April 2025. Patients were randomly assigned using a random number table to two groups (n = 37 each): the experimental group received NIPPV, while the control group underwent conventional invasive mechanical ventilation. Intergroup differences were compared. Results: Compared with the control group, the experimental group demonstrated significantly higher PaO2 and oxygenation index, significantly lower PaCO2, significantly reduced levels of WBC, CRP, and PCT, significantly higher overall efficacy rate, and significantly lower incidence of adverse reactions after treatment (p < 0.05). Pre-treatment PaO2, oxygenation index, PaCO2, WBC, CRP, and PCT levels showed no significant differences between groups (p > 0.05). Conclusion: Non-invasive positive pressure ventilation demonstrates favorable outcomes in respiratory support for severe pneumonia.展开更多

Some studies have shown that elastography can detect both the progression and regression of fibrosis. Similarly, research results have been analysed and direct and indirect serum markers of hepatic fibrosis have shown high diagnostic accuracy for advanced fibrosis/cirrhosis. The prognosis of different stages of cirrhosis is well established and various staging systems have been proposed, largely based on clinical data. However, it is still unknown if either noninvasive markers of liver fibrosis or elastography may contribute to a more accurate staging of liver cirrhosis, in terms of prognosis and fibrosis regression after effective therapy. In fact, not enough studies have shown both the fibrosis regression in different cirrhosis stages and the point beyond which the prognosis does not change- even in the event of fibrosis regression. Therefore, future studies are needed to validate noninvasive methods in predicting the different phases of liver cirrhosis.展开更多

Methods: A number of 96 acute myocardial infarction patients accompanied with heart failure after PCI hospitalized in the People's Hospital of Sanya during February 2012 to October 2015 were selected. They were randomly divided into the therapy group(n = 50) and control group(n = 46). On the basis of routine treatment, patients in the therapy group were treated with intravenous rh BNP(1.5 μg/kg was intravenous injection with uniform speed of 3 min, followed by continuous infusion 0.007 5 μg/kg·min for 72 h), while the control group received conventional treatment. Bio Z-2011 non-invasive hemodynamic real-time monitoring system was used to monitor the hemodynamic parameters changes and the leves of plasma pro-BNP, serum creatinine, serum potassium, serum sodium and urine volume of each group before and after treating for 30 min, 1 h, 3 h, 6 h, 12 h, 24 h, 48 h, 72 h. Results: Patients in the therapy group showed no effect on heart rate, while after 30 min of intravenous injection of rh BNP, CO, CI, SV, and SI increased significantly and LVET and TFC reduced at the same time, which had certain effect on blood pressure(SBP/DBP). Compared with the control group, the therapy group showed a faster and more effective improvement on haemodynamics. Conclusions: Acute myocardial infarction patients complicated with left heart failure after primary PCI can significantly improve hemodynamics by treating with rh BNP.展开更多

However, during the last 20 years, it has become evident that this "gold-standard" is imperfect; even according to its proponents, it is only "the best" among available methods. Attempts at uncovering non-invasive diagnostic tools have yielded multiple scores, formulae, and imaging modalities. All are better tolerated, safer, more acceptable to the patient, and can be repeated essentially as often as required. Most are much less expensive than liver biopsy. Consequently, their use is growing, and in some countries the number of biopsies performed, at least for routine evaluation of hepatitis B and C, has declined sharply. However, the accuracy and diagnostic value of most, if not all, of these methods remains controversial. In this review for the practicing physician, we analyze established and novel biomarkers and physical techniques. We may be witnessing in recent years the beginning of the end of the first phase for the development of non-invasive markers. Early evidence suggests that they might be at least as good as liver biopsy. Novel experimental markers and imaging techniques could produce a dramatic change in diagnosis in the near future.展开更多

AST-to-Platelet ratio （APRI）, Forns＇ index, AST-to-ALT Ratio, Goteborg University Cirrhosis Index （GUCD, Hui＇s model and Fibrotest were measured on the day of liver biopsy. The performance of these methods and of sequential algorithms combining Fibrotest, APRI and biopsy was defined by positive （PPV） and negative （NPV） predictive values, accuracy and area under the curve （AUC）. RESULTS： PPV for significant fibrosis was excellent （100%） with Forns and high （〉 92%） with APR1, GUCI, Fibrotest and Hui. However, significant fibrosis could not be excluded by any marker （NPV 〈 65%）. Fibretest had the best PPV and NPV for cirrhosis （87% and 90%, respectively）. Fibrotest showed the best AUC for both significant fibrosis and cirrhosis （0.85 and 0.76, respectively）. Stepwise combination algorithms of APR1, Fibrotest and biopsy showed excellent performance （0.96 AUC, 100% NPV） for significant fibrosis and 0.95 AUC, 98% NPV for cirrhosis, with 50%-80% reduced need for liver biopsy. CONCLUSION： In CHB sequential combination of APRI, Fibrotest and liver biopsy greatly improves the diagnostic performance of the single non-invasive markers. Need for liver biopsy is reduced by 50%-80% but cannot be completely avoided. Non-invasive markers and biopsy should be considered as agonists and not antagonists towards the common goal of estimating liver fibrosis.展开更多

文摘BACKGROUND Internet gaming disorder(IGD)is a growing concern among adolescents and adults,necessitating effective treatment strategies beyond pharmacological interventions.AIM To evaluated the effectiveness of non-invasive interventions for treating IGD among adolescents and adults.METHODS A total of 11 randomized controlled trials published between 2020 and 2025 were included in this meta-analysis,encompassing 1208 participants from diverse geographic and cultural contexts.The interventions examined included cognitive behavioral therapy(CBT),internet-based CBT,neurofeedback,virtual reality therapy,abstinence-based programs,and school-based prevention.The primary outcomes assessed were reductions in gaming time and IGD severity.Secondary outcomes included improvements in mood,anxiety,and psychosocial functioning(e.g.,stronger peer relationships,better academic or work performance,and healthier daily-life role fulfillment).RESULTS The pooled standardized mean difference for IGD symptom reduction significantly favored non-invasive interventions(Hedges’g=0.56,95%CI:0.38-0.74,P<0.001),with moderate heterogeneity observed(I2=47%).Subgroup analyses indicated that CBT-based programs,both in-person and online,yielded the strongest effects,particularly when caregiver involvement or self-monitoring was incorporated.Funnel plot asymmetry was minimal,suggesting a low risk of publication bias.CONCLUSION These findings support the efficacy of scalable,low-risk non-invasive interventions as first-line treatment options for IGD,particularly in youth populations.Future studies should prioritize investigating long-term outcomes,comparing the effectiveness of different non-invasive modalities,and developing culturally adaptive delivery methods.

文摘Accurate real-time monitoring of internal temperature in lithium-ion batteries remains critical for preventing thermal runaway,as conventional approaches sacrifice either computational efficiency or cross-scenario robustness.We present a generalized fuzzy physics-informed framework that distills thermally sensitive electrochemical processes while circumventing redundant physical constraints,thereby establishing an explicit mechanism-constrained mapping between frequency-domain signals and internal temperature.This framework facilitates online thermal estimation,with dynamic validations in LiFePO_4/graphite 18650-type cells confirming real-time capability with near-instantaneous acquisition(~6 s per measurement),exceptional accuracy(±0.5℃) within the operational temperature range(30-50℃),and operational resilience across 20 %-80 % state-of-charge.The framework maintains predictive fidelity(±1.0℃ at 30℃ and ±4.0℃ at 60℃,95 % prediction intervals) across 80 %-100 % state-of-health while demonstrating adaptability to cathode materials and structural architectures.This strategy resolves the competing imperatives of physical interpretability,computational efficiency,and crossscenario generalizability,offering a universal paradigm for embedded thermal management in safetycritical applications.

文摘Metabolic dysfunction-associated steatotic liver disease(MASLD)requires accurate liver fibrosis assessment for management.While liver biopsy remains the gold standard,its invasiveness drives demand for non-invasive biomarkers.This review evaluates blood biomarkers for MASLD fibrosis staging.Established scores(fibrosis-4,non-alcoholic fatty liver disease fibrosis score)offer accessible screening but exhibit variable performance influenced by age,obesity,and comorbidities.Patented panels(e.g.,enhanced liver fibrosis test,FibroMeter)improve accuracy by integrating extracellular matrix or metabolic markers,though context-specific thresholds are essential.Emerging biomarkers like propeptide of type 3 collagen,Mac-2 binding protein glycosylation isomer,epigenetic markers(proliferator-activated receptor-γmethylation),and angiopoietin-like proteins a family of eight glycoproteins show promise but require large-scale validation.Genetic risk scores and multi-omics approaches face generalizability challenges.Integration strategies,such as combining serum biomarkers with liver stiffness measurement via Agile scores,enhance diagnostic precision and reduce indeterminate classifications.Current tools aid risk stratification,but no single biomarker replicates biopsy-level precision.Future efforts must prioritize MASLD-specific diagnostic frameworks,standardized protocols,and multi-modal integration to enhance clinical utility and address MASLD’s growing burden.
文摘Hyaline Membrane Disease(HMD)in newborns,also known as neonatal respiratory distress syndrome,is a common critical illness in premature infants,with an incidence inversely correlated with gestational age,posing a serious threat to the life and health of newborns.This paper systematically reviews the core pathogenesis of HMD,focusing on the abnormal metabolism of pulmonary surfactant(PS),genetic factors,immature lung development,and the synergistic effects of inflammatory oxidative stress.It highlights the advances in non-invasive ventilation(NIV)therapy for HMD,including the mechanisms of action,clinical application effects,and optimization strategies of mainstream modalities such as nasal continuous positive airway pressure ventilation(NCPAP),nasal intermittent positive pressure ventilation(NIPPV),and heated humidified high-flow nasal cannula ventilation(HHHFNC).The aim is to provide references for standardized clinical treatment.
文摘Chronic kidney disease(CKD)is a degenerative disorder that affects millions of people throughout the world,causing considerable morbidity and healthcare burden.Frequent blood sampling is the current gold standard for monitoring CKD to evaluate biochemical and mineral indicators.However,there are draw-backs to frequent blood draws,such as pain for patients,the possibility of infe-ction,and higher medical expenses.Saliva-based diagnostics offer advantages such as ease of collection,reduced invasiveness,and improved patient compli-ance.A comprehensive literature review was conducted to analyze studies eva-luating the diagnostic utility of salivary creatinine,urea,calcium,and parathyroid hormone(PTH)in patients with CKD.Various saliva collection methods,inc-luding stimulated and unstimulated approaches,were investigated for efficiency and reliability,and a correlation was shown between serum and salivary crea-tinine,urea,PTH,and calcium levels,indicating their potential as CKD biomar-kers.Despite these promising findings,challenges such as standardization of collection methods,variability in salivary flow rates,and predictive value in association with blood parameters are addressed to ensure clinical applicability.This review explores the potential and challenges of saliva as a non-invasive alternative for CKD diagnostics.

文摘Flip-flow screens offer unique advantages in grading fine-grained materials.To address inaccuracies caused by sensor vibra-tions in traditional contact measurement methods,we constructed a non-invasive measurement system based on electrical and optical sig-nals.A trajectory tracking algorithm for the screen-body was developed to visually measure the kinematics.Employing the principle oflaser reflection for distance measurement,optical techniques were performed to capture the kinematic information of the screen-plate.Ad-ditionally,by using Wi-Fi and Bluetooth transmission of electrical signals,tracer particle tracking technology was implemented to elec-trically measure the kinematic information of mineral particles.Consequently,intelligent fusion and perception of the kinematic informa-tion for the screen-body,screen-plate,and particles in the screening system have been achieved.

文摘Patients with acute exacerbation of chronic obstructive pulmonary disease(COPD)often suffer from respiratory failure and require respiratory support therapy.High-flow nasal cannula oxygen therapy(HFNC)and non-invasive positive pressure ventilation(NIPPV)are commonly used non-invasive respiratory support methods.HFNC can provide precisely heated and humidified high-flow oxygen,reducing dead space and increasing alveolar ventilation.NIPPV can supply stable high-concentration oxygen and improve gas exchange.This article reviews the application of HFNC and NIPPV in the acute exacerbation stage of COPD,aiming to provide references for reasonable clinical selection.
文摘Transient elastography and the acoustic radiation force impulse techniques may play a pivotal role in the study of liver fibrosis. Some studies have shown that elastography can detect both the progression and regression of fibrosis. Similarly, research results have been analysed and direct and indirect serum markers of hepatic fibrosis have shown high diagnostic accuracy for advanced fibrosis/cirrhosis. The prognosis of different stages of cirrhosis is well established and various staging systems have been proposed, largely based on clinical data. However, it is still unknown if either noninvasive markers of liver fibrosis or elastography may contribute to a more accurate staging of liver cirrhosis, in terms of prognosis and fibrosis regression after effective therapy. In fact, not enough studies have shown both the fibrosis regression in different cirrhosis stages and the point beyond which the prognosis does not change- even in the event of fibrosis regression. Therefore, future studies are needed to validate noninvasive methods in predicting the different phases of liver cirrhosis.

文摘Objective: To investigate the effects of exogenous recombinant human brain natriuretic peptide(rh BNP) after primary percutaneous coronary intervention(PCI) on non-invasive hemodynamic in acute myocardial infarction patients with left ventricular failure. Methods: A number of 96 acute myocardial infarction patients accompanied with heart failure after PCI hospitalized in the People's Hospital of Sanya during February 2012 to October 2015 were selected. They were randomly divided into the therapy group(n = 50) and control group(n = 46). On the basis of routine treatment, patients in the therapy group were treated with intravenous rh BNP(1.5 μg/kg was intravenous injection with uniform speed of 3 min, followed by continuous infusion 0.007 5 μg/kg·min for 72 h), while the control group received conventional treatment. Bio Z-2011 non-invasive hemodynamic real-time monitoring system was used to monitor the hemodynamic parameters changes and the leves of plasma pro-BNP, serum creatinine, serum potassium, serum sodium and urine volume of each group before and after treating for 30 min, 1 h, 3 h, 6 h, 12 h, 24 h, 48 h, 72 h. Results: Patients in the therapy group showed no effect on heart rate, while after 30 min of intravenous injection of rh BNP, CO, CI, SV, and SI increased significantly and LVET and TFC reduced at the same time, which had certain effect on blood pressure(SBP/DBP). Compared with the control group, the therapy group showed a faster and more effective improvement on haemodynamics. Conclusions: Acute myocardial infarction patients complicated with left heart failure after primary PCI can significantly improve hemodynamics by treating with rh BNP.
文摘The evaluation and follow up of liver fibrosis and cirrhosis have been traditionally performed by liver biopsy. However, during the last 20 years, it has become evident that this "gold-standard" is imperfect; even according to its proponents, it is only "the best" among available methods. Attempts at uncovering non-invasive diagnostic tools have yielded multiple scores, formulae, and imaging modalities. All are better tolerated, safer, more acceptable to the patient, and can be repeated essentially as often as required. Most are much less expensive than liver biopsy. Consequently, their use is growing, and in some countries the number of biopsies performed, at least for routine evaluation of hepatitis B and C, has declined sharply. However, the accuracy and diagnostic value of most, if not all, of these methods remains controversial. In this review for the practicing physician, we analyze established and novel biomarkers and physical techniques. We may be witnessing in recent years the beginning of the end of the first phase for the development of non-invasive markers. Early evidence suggests that they might be at least as good as liver biopsy. Novel experimental markers and imaging techniques could produce a dramatic change in diagnosis in the near future.
文摘Liver cirrhosis is a common and growing public health problem globally.The diagnosis of cirrhosis portends an increased risk of morbidity and mortality.Liver biopsy is considered the gold standard for diagnosis of cirrhosis and staging of fibrosis.However,despite its universal use,liver biopsy is an invasive and inaccurate gold standard with numerous drawbacks.In order to overcome the limitations of liver biopsy,a number of non-invasive techniques have been investigated for the assessment of cirrhosis.This review will focus on currently available non-invasive markers of cirrhosis.The evidence behind the use of these markers will be highlighted,along with an assessment of diagnostic accuracy and performance characteristics of each test.Non-invasive markers of cirrhosis can be radiologic or serum-based.Radiologic techniques based on ultrasound,magnetic resonance imaging and elastography have been used to assess liver fibrosis.Serum-based biomarkers of cirrhosis have also been developed.These are broadly classified into indirect and direct markers.Indirect biomarkers reflect liver function,which may decline with the onset of cirrhosis.Direct biomarkers,reflect extracellular matrix turnover,and include molecules involved in hepatic fibrogenesis.On the whole,radiologic and serum markers of fibrosis correlate well with biopsy scores,especially when excluding cirrhosis or excluding fibrosis.This feature is certainly clinically useful,and avoids liver biopsy in many cases.
文摘Liver fibrosis is an important pathological precondition for hepatocellular carcinoma.The degree of hepatic fibrosis is positively correlated with liver cancer.Liver fibrosis is a series of pathological and physiological process related to liver cell necrosis and degeneration after chronic liver injury,which finally leads to extracellular matrix and collagen deposition.The early detection and precise staging of fibrosis and cirrhosis are very important for early diagnosis and timely initiation of appropriate therapeutic regimens.The risk of severe liver fibrosis finally progressing to liver carcinoma is＆gt;50%.It is known that biopsy is the gold standard for the diagnosis and staging of liver fibrosis.However,this method has some limitations,such as the potential for pain,sampling variability,and low patient acceptance.Furthermore,the necessity of obtaining a tissue diagnosis of liver fibrosis still remains controversial.An increasing number of reliable non-invasive approaches are now available that are widely applied in clinical practice,mostly in cases of viral hepatitis,resulting in a significantly decreased need for liver biopsy.In fact,the noninvasive detection and evaluation of liver cirrhosis now has good accuracy due to current serum markers,ultrasound imaging,and magnetic resonance imaging quantification techniques.A prominent advantage of the non-invasive detection and assessment of liver fibrosis is that liver fibrosis can be monitored repeatedly and easily in the same patient.Serum biomarkers have the advantages of high applicability（〉95%）and good reproducibility.However,their results can be influenced by different patient conditions because none of these markers are liver-specific.The most promising techniques appear to be transient elastography and magnetic resonance elastography because they provide reliable results for the detection of fibrosis in the advanced stages,and future developments promise to increase the reliability and accuracy of the staging of hepatic fibrosis.This article aims to describe the recent progress in the development of non-invasive assessment methods for the staging of liver fibrosis,with a special emphasize on computer-aided quantitative and deep learning methods.
文摘AIM： To assess the performance of several noninvasive markers and of our recently proposed stepwise combination algorithms to diagnose significant fibrosis （F ≥ 2 by METAVIR） and cirrhosis （F4 by METAVIR） in chronic hepatitis B （CHB）.METHODS： One hundred and ten consecutive patients （80 males, 30 females, mean age： 42.6 ± 11.3） with CHB undergoing diagnostic liver biopsy were included. AST-to-Platelet ratio （APRI）, Forns＇ index, AST-to-ALT Ratio, Goteborg University Cirrhosis Index （GUCD, Hui＇s model and Fibrotest were measured on the day of liver biopsy. The performance of these methods and of sequential algorithms combining Fibrotest, APRI and biopsy was defined by positive （PPV） and negative （NPV） predictive values, accuracy and area under the curve （AUC）. RESULTS： PPV for significant fibrosis was excellent （100%） with Forns and high （〉 92%） with APR1, GUCI, Fibrotest and Hui. However, significant fibrosis could not be excluded by any marker （NPV 〈 65%）. Fibretest had the best PPV and NPV for cirrhosis （87% and 90%, respectively）. Fibrotest showed the best AUC for both significant fibrosis and cirrhosis （0.85 and 0.76, respectively）. Stepwise combination algorithms of APR1, Fibrotest and biopsy showed excellent performance （0.96 AUC, 100% NPV） for significant fibrosis and 0.95 AUC, 98% NPV for cirrhosis, with 50%-80% reduced need for liver biopsy. CONCLUSION： In CHB sequential combination of APRI, Fibrotest and liver biopsy greatly improves the diagnostic performance of the single non-invasive markers. Need for liver biopsy is reduced by 50%-80% but cannot be completely avoided. Non-invasive markers and biopsy should be considered as agonists and not antagonists towards the common goal of estimating liver fibrosis.
文摘Alcoholic liver disease(ALD)is the most common liver disease in the Western world.For many reasons,it isunderestimated and underdiagnosed.An early diagnosis is absolutely essential since it(1)helps to identify patients at genetic risk for ALD;(2)can trigger efficient abstinence namely in non-addicted patients;and(3)initiate screening programs to prevent life-threateningcomplications such as bleeding from varices,spontaneous bacterial peritonitis or hepatocellular cancer.The two major end points of ALD are alcoholic liver cirrhosis and the rare and clinically-defined alcoholic hepatitis(AH).The prediction and early diagnosis of both entities is still insufficiently solved and usually relies on acombination of laboratory,clinical and imaging findings.It is not widely conceived that conventional screeningtools for ALD such as ultrasound imaging or routine laboratory testing can easily overlook ca.40%of manifest alcoholic liver cirrhosis.Non-invasive methods such as transient elastography(Fibroscan),acoustic radiation force impulse imaging or shear wave elastography have significantly improved the early diagnosis of alcoholiccirrhosis.Present algorithms allow either the exclusion or the exact definition of advanced fibrosis stages in ca.95%of patients.The correct interpretation of liver stiffness requires a timely abdominal ultrasound and actual transaminase levels.Other non-invasive methods such as controlled attenuation parameter,serum levels of M30 or M65,susceptometry or breath tests are under current evaluation to assess the degree of steatosis,apoptosis and iron overload in these patients.Liver biopsy still remains an important option to rule out comorbidities and to confirm the prognosis namely for patients with AH.
