AIM:To identify surrogate clinical bio-markers for profiling the eosinophilic status of an individual patient over induced sputum analysis.METHODS:We conducted a cross-sectional study on 100 asthmatic patients whose induced sputum was successfully collected.Subjects were further classified into either EA or NEA based on whether the percentage of sputum eosinophil count(SEC％)was≥3％.Demographic and clinical data were col-lected,including basic information,routine blood tests,lung function tests,bronchodilator reversibili-ty tests,fractional exhaled nitric oxide(FeNO),the Asthma Control Test(ACT)and the Asthma Control Questionnaire(ACQ).All variables significantly asso-ciated with EA were candidates for multivariate lo-gistic regression analysis.A scoring system present-ed as a nomogram for the prediction of EA was de-veloped.RESULTS:In the univariate analysis,com-pared with NEA subjects,those with EA were of older age and had worse asthma control and lung function in addition to higher values of blood eosin-ophils,serum IgE and FeNO.Multivariable logistic regression analysis revealed that age,FeNOx serum IgE and blood eosinophil count(BEC)were identi-fied as independent risk factors for eosinophilic asthma,which were all included in the nomogram.CONCLUSION:A combination assessment including age,FeNOx serum IgE and BEC could be applicable to clinicians in identifying eosinophilic asthma and is easier,faster,more inexpensive and more readily available than the induced sputum test.

Objective:To evaluate the utility of ultrasonographic monitoring of the rectus femoris muscle—specifically, the rates of change in thickness and cross-sectional area (CSA)—in assessing nutritional status and long-term functional outcomes in patients with sepsis.Methods:In this prospective observational study, sepsis patients admitted to the ICU of the Second Affiliated Hospital of Soochow University between October 2023 and October 2024 were classified by nutritional status at discharge using the Global Leadership Initiative on Malnutrition (GLIM) criteria. Differences in serial ultrasound-measured rectus femoris thickness and CSA on days 1, 3, 5, and 7 were compared between malnourished and non-malnourished groups. The predictive value of these ultrasound parameters for malnutrition was analyzed. Functional prognosis was assessed using the Sarcopenia Assessment Scale, Short Physical Performance Battery, and Manual Muscle Testing, with correlations to muscle changes examined.Results:Of the 71 enrolled patients (median age 73.00 [ IQR: 61.00–80.00]; 47.89% female, 52.11% male), those with malnutrition showed significantly greater variation rates in rectus femoris thickness and CSA on days 3, 5, and 7 compared to the non-malnourished group ( P < 0.05). ROC analysis revealed that the day-7 CSA variation rate had the highest predictive value for malnutrition (AUC = 0.817, 95% CI: 0.713-0.930). These muscle variation rates also correlated strongly with conventional nutritional markers such as BMI, albumin, and urea. Similarly, patients with impaired functional outcomes exhibited higher variation rates in muscle parameters on days 3, 5, and 7 ( P < 0.05), with the day-7 CSA variation rate being most predictive of functional prognosis (AUC = 0.749, 95% CI: 0.632-0.867). Conclusions:Ultrasonographic assessment of rectus femoris thickness and CSA variation rates provides a valuable tool for evaluating nutritional status and predicting functional prognosis in sepsis patients, outperforming traditional biomarkers. This method shows promise for guiding individualized nutrition support and rehabilitation strategies to improve long-term outcomes.

ObjectiveTo explore the possible mechanism of the Yiqi Jiedu formula （YQ） in treating ischemic stroke （IS） from the perspective of the microbial-gut-brain axis （MGBA）. MethodRats were randomly divided into five groups， with six in each group， including sham surgery group， model group， and low， medium， and high dose YQ groups （1， 5， and 25 mg·kg^-1）. Except for the sham surgery group， all other groups were established with a middle cerebral artery occlusion （MCAO） model using the thread occlusion method. The success of modeling was determined through neurobehavioral scoring， and the protective effect of YQ on IS was evaluated. Then， the changes in gut microbiota before and after MCAO modeling and YQ administration were compared using 16S rDNA sequencing technology， and the possible biological pathways related to the effect of this formula were analyzed. The expression of inflammatory factors such as interleukin-6 （IL-6）， interleukin-17A （IL-17A）， and interleukin-10 （IL-10） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the expression of tight junction proteins ZO-1 and Occludin in brain and intestinal tissue， and hematoxylin-eosin staining （HE） was used to observe pathological changes in the cerebral cortex and colon， so as to validate the possible mechanism of action. ResultYQ significantly improved the neurobehavioral score of MCAO rats （P<0.01） and played a good regulatory role in intestinal microbial disorders caused by enriched pathogens and opportunistic pathogens during the acute phase. Among them， significantly changed microorganisms include Morgentia， Escherichia Shigella， Adlercreutzia， and Androbacter. Bioinformatics analysis found that these bacteria may be related to the regulation of inflammation in the brain. Compared with the blank group， the detection of inflammatory factors in the serum of IS model rats showed an increase in inflammatory factors IL-6 and IL-17A （P<0.01） and a decrease in the content of anti-inflammatory factor IL-10 （P<0.01）. Compared with the model group， the content of inflammatory factors IL-6 and IL-17A in the serum of the treatment group decreased （P<0.05）， and that of anti-inflammatory factor IL-10 increased （P<0.01）. The expression results of barrier proteins ZO-1 and Occludin in brain and intestinal tissue showed that the expression levels of both decreased in IS model rats （P<0.05）， while the expression levels of both increased in the treatment group （P<0.05）. ConclusionAcute cerebral ischemia can lead to an imbalance of intestinal microbiota and damage to the intestinal barrier， and it can increase intestinal permeability. YQ can regulate intestinal microbiota imbalance caused by ischemia， inhibit systemic inflammatory response， and improve the disruption of the gut-blood brain barrier， preventing secondary cascade damage to brain tissue caused by inflammation. The MGBA may be an important mechanism against the IS.

Objective:To investigate the effect of modified percutaneous closure in the treatment of ventricular septal rupture.Methods:This study is a retrospective cohort study. Forty-four patients with ventricular septal rupture who underwent percutaneous closure at the Fuwai Central China Cardiovascular Hospital from December 2017 to October 2023 were included. According to the closure method, patients were divided into the modified group (11 cases) and the traditional group (33 cases). Surgical success was defined as successful placement of the occluder. The operation time, X-ray intake, sheath bending rate, incidence of ventricular fibrillation and pericardial tamponade, and postoperative residual shunt were compared between the two groups.Results:The age of the patients was (75.0±5.7) years, with 20 (45%) males. There were 3 cases of operation failure in the traditional group, while all patients in the modified group were successfully occluded. The procedure time in the modified group was shorter than that in the traditional group (40 (35, 45) min vs. 60 (50, 65)min, P<0.001); X-ray dose intake was lower ((442.43±73.26)mGy vs. (784.45±247.78)mGy, P<0.001). There was no occurrence of sheath bending in the modified group, while the incidence of sheath bending in the traditional surgery group was 46% (15/33), and the difference was statistically significant ( P=0.017). Intraoperative ventricular fibrillation and pericardial tamponade occurred in 7 cases (21%) and 2 cases (6%) in the traditional group respectively, while none occurred in the modified group, but the differences between the groups were not statistically significant (both P>0.05). There was no significant difference in residual shunt between the two groups (3.6 (2.5, 4.3) mm vs. 4.0 (3.5, 4.5) mm, P=0.506). Conclusion:The procedure of modified ventricular septal rupture closure is more simplified, with a lower incidence ofventricular fibrillation and pericardial tamponade.

Objective:To establish a method for correction of tail vein extravasation based on PET images and to improve the accuracy of SUV.Methods:The simulation method was established by phantom on Nano PET/CT and images were reconstructed by a three-dimensional ordered-subsets exception maximum algorithm. PET images were analyzed by using the Interview Fusion 1.0 software. The optimal scanning time and the ROI delineated method were found. The accuracy of the simulation method was verified by comparing the activity of simulation method with the mice tail activity measured by the dose calibrator directly on Kunming (KM) mouse ( n=11). Using the simulation method, the impact of extravasation on SUV was proved. Independent-sample t test was used to analyze data. Results:Ten minutes was selected as the optimal scanning time and SUV max 42% threshold was selected as the ROI delineated method. The specific correction formula was as follows: actual activity=image activity/(4.48× V+ 77.05)×100 (0.3 MBq/ml≤leakage concentration<6.5 MBq/ml); actual activity=image activity/(6.65× V+ 71.10)×100 (6.5 MBq/ml

Objective:To study the characteristics of breath sound spectroscopy in chronic obstructive pulmonary disease(COPD) patients with different lung function grades, to preliminarily determine the characteristic parameters and indicators of breath sound spectrograms with different lung function grades of COPD, and to explore the visualization and measurability of the differences in respiratory auscultation in patients with different lung function grades.Methods:Patients diagnosed and treated in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine Chongming Branch from October 2018 to December 2020 were selected. Fifty-two patients with COPD (22 patients with moderate to moderate obstructive ventilation dysfunction (mild to moderate group), 30 patients with severe obstructive ventilation dysfunction (severe group)) and 36 normal controls (control group) were selected. The respiratory sounds were sampled with an electronic stethoscope and transmitted to the audit audio software to calculate the relevant data of respiratory sound pressure level (SPL) and the ratio to minute ventilation (VE) of samples with different lung function grades. A retrospective case-control study was used. The data with normal distribution were analyzed by one-way ANOVA, and the pairwise comparison was performed by SNK- q test. Results:The breathing audio frequency of mild-moderate, severe COPD patients and the control group has a sound pressure difference of (-0.5±2.2) dB and (-1.6±6.1) dB, (0.7±4.0) dB, and there was significant difference between each group ( F=2.64, P=0.038). The sound pressure level per minute ventilation (SPL 50-200/VE) of respiratory sound inspiratory phase in COPD patients with mild to moderate and severe obstructive ventilation dysfunction and the control group were (5.7±1.8) dB/L, (6.1±2.3) dB/L and (5.4±0.9) dB/L, respectively. The expiratory SPL 50-200/VE were (5.8±1.7), (6.3±2.2) and (5.3±1.2) respectively. There was significant difference among the three groups ( Finhalation=3.26, P=0.048; Frespiration=2.44, P=0.045). ROC curve results showed that SPL 50-200/VE in the inspiratory phase, SPL 50-200/VE in the expiratory phase, and sound pressure difference to assess different grades of obstructive ventilatory dysfunction had diagnostic value (AUC values were 0.697, 0.725 and 0.686, respectively; and P values were 0.015, 0.005 and 0.022, respectively). In some patients with COPD, abnormally high energy levels may appear in the time-frequency diagram of breath sounds. Conclusion:There are significant differences in respiratory audio spectrum analysis between patients with different degrees of obstructive ventilation dysfunction and those with normal ventilation function, which can provide a basis for auxiliary judgment of obstructive ventilation dysfunction.

Objective:To investigate the effect of diabetes mellitus in the elderly on memory function in patients with mild cognitive impairment(MCI).Methods:Totally 449 community residents were selected for a 2-year follow-up survey.Montreal Cognitive Assessment(MoCA)and Mini-Mental State Examination(MMSE)were selected for overall cognitive function assessment.Fuld Object Memory(FOM)and Digital Span Test(DST)were used to evaluate delayed recall and instantaneous memory.Demographic data such as gender, age, education level, marital history, annual income, blood pressure, medical history etc.were collected.The glycosylated hemoglobin, fasting insulin, and carotid artery intima-media thickness were checked regularly.All subjects were grouped into non-diabetes mellitus normal cognitive group(NDM-NC group), non-diabetes mellitus mild cognitive impairment group(NDM-MCI group), diabetes mellitus normal cognitive group(DM-NC group)and diabetes mellitus mild cognitive impairment group(DM-MCI group).Results:In cross-sectional observation, the first, second, and last recall scores in the FOM showed a decreasing trend in the DM-MCI group, showed a word "U" -shaped fluctuation trend in the DM-NC group and the NDM-MCI group, and showed no significant change in the NDM-NC group.There were no significant differences in DST anterior-backward test scores between the DM-MCI group and NDM-MCI group(all P>0.05).Through longitudinal follow-up and two-by-two comparison with the other three groups, the average value of glycosylated hemoglobin in the DM-MCI group(6.78±0.60)% was the highest, and the differences were statistically significant( P<0.05).During follow-up, the average carotid intima-media thickness(CIMT)was higher in the DM-MCI group(1.03±0.20)mm than in NDM-NC group(0.89±0.20)mm( P<0.05), and the difference was statistically significant.Comparing with the other three longitudinal follow-up groups, the CIMT thickening speed in DM-MCI group was fastest. Conclusions:Elderly DM patient population have a higher prevalence of MCI, and their memory function fluctuates or declines significantly.Therefore, regular detection of memory function is conducive to delaying the progression of DM and MCI.
