Objective:To quantify thoracic and abdominal movements during breathing using inertial measurement units (IMUs) and to build a machine learning model which identifies the abdominal breathing (AB) pattern.Methods:Ten rehabilitation therapists formed the study′s professional group, while 15 patients receiving AB training comprised the validation group. Two synchronized IMUs were applied to capture breathing motions during natural breathing (NB), deep breathing (DB) and AB. Six kinematic features were extracted from each respiratory cycle, and inter-group and inter-pattern differences were analyzed. Correlation analysis was also performed with manually measured changes in thoracic and abdominal circumferences. A support vector classification model for AB pattern detection was then developed using data from the professional and validation groups.Results:A total of 1113 respiratory cycles were extracted and analyzed. The breathing pattern significantly influenced all of the kinematic features studied (0.21≤partial η 2≤0.65, all P≤0.001). The ranges of the angles in medial-lateral axis of the IMUs showed strong correlation with the changes in abdominal and thoracic circumferences (ρ1=0.928, ρ2=0.807, P≤0.001 in both cases). A greater range of abdominal angles was found during AB compared to the other patterns. The best of the models achieved an F1 score of 0.970 (sensitivity: 0.983, specificity: 0.980) in validation. Conclusions:AB generates the greatest abdominal movement. Combining IMUs and machine learning can provide real-time quantification of chest movement and accurate detection of AB during breathing training.

Autoimmunity and the activation of immune cells are closely related to the occurrence of chronic spontaneous urticaria, while the gut microbiota participates in multiple physiological activities including the regulation of the host's immunity. Gut microbiota in patients with chronic spontaneous urticaria has unique structural composition and metabolic features. Gut microbiota imbalance and secondary short-chain fatty acid deficiency may be important causes for the occurrence of the disease and aggravation of inflammation. Studies have shown that probiotics can improve the clinical manifestations of patients with urticaria. This review summarizes the research progress in the correlations of gut microbiota and short-chain fatty acids with chronic spontaneous urticaria.

Objective To explore the difference in clinical efficacy of sacubitril valsartan(SV)and enalapril in the treatment of elderly patients with chronic heart failure with reduced ejection frac-tion(HFrEF).Methods A total of 126 elderly patients with chronic HFrEF admitted in our de-partment between January 2020 and January 2023 were prospectively recruited and randomly di-vided into control group(enalapril treatment,63 cases)and observation group(SV treatment,63 cases).After 3 months of treatment,the improvement rate of NYHA cardiac function grade,and changes in cardiac function indicators[6-minute walking distance(6MWD),NT-proBNP,LVEDD,LVEF],and echocardiographic indicators[left ventricular myocardial work(Tei)index,stroke volume,cardiac output(CO)]before and after treatment,adverse reactions during treat-ment and prognosis were compared between the two groups.Results The improvement rate of NYHA grade was significantly higher in the observation group than the control group(80.95％vs 65.08％,P＜0.05).The results of 6MWD,LVEF,stroke volume and CO were obviously higher in both groups after treatment than before treatment(P＜0.05).The results of 6MWD,LVEF,stroke volume and CO were notably higher in the observation group than the control group(P＜0.01).The SBP,DBP,NT-proBNP,heart rate,LVEDD and LV Tei index were decreased after treatment in both groups,and those in the observation group were even lower than those in the control group(P＜0.05,P＜0.01).As of April 2024,the readmission rates due to HF was re-markably lower in the observation group than the control group(7.94％vs 20.63％,P＜0.05),but no statistical difference was seen in the mortality or the incidence of adverse reactions be-tween them(P＞0.05).Conclusion SV is superior to enalapril in improving the efficacy,cardiac function and cardiac load of elderly HFrEF patients,with advantages of reducing the incidence of readmission but not increasing adverse reactions.

Chronic spontaneous urticaria (CSU) is a recurrent systemic inflammatory disease. At present, there are few biological indicators that can effectively reflect CSU activity in clinical practice, and some indicators have not been widely used. To identify sensitive and easy-to-check indicators may be helpful for the diagnosis and treatment of as well as prediction of therapeutic efficacy in CSU. This review comprehensively summarizes current clinical application of indicators related to CSU activity, in order to provide a reference for clinical practice and related scientific research.

Objective:To explore the clinical correlation between peripheral blood basophil levels and chronic sinusitis （CRS） subtypes. Methods:One hundred and twenty-six patients with CRS and 103 healthy cases from physical examination admitted to the First Affiliated Hospital of Soochow University from January 2021 to October 2022 were retrospectively analyzed. According to the histopathological classification, CRS patients were divided into eosinophilic chronic sinusitis （eCRS） group （47 cases） and non eosinophilic chronic sinusitis （non-eCRS） group （79 cases）. The differences among the three groups in peripheral blood inflammation cell counts, eosinophils-to-basophils ratio（bEBR）, basophils-to-neutrophils ratio（BNR）, basophils-to-lymphocytes ratio（BLR）, basophils-to-monocytes ratio（BMR） were compared, and study the correlation between each index and Lund-Mackay score, and the correlation between basophils in peripheral blood and other inflammatory cells. Results:The counts of basophils in the peripheral blood of the healthy control group, eCRS group and non-eCRS group were 0.03±0.01, 0.04±0.02, 0.03±0.02, respectively, the eosinophils-to-basophils ratio（bEBR） were 5.64±4.22, 8.38±5.95, 4.55±3.90, the basophils-to-neutrophils ratio（BNR） were 0.01±0, 0.01±0.01, 0.01±0.01, and the basophils-to-lymphocytes ratio（BLR） were 0.01±0.01, 0.02±0.01, and 0.02±0.01, respectively, the basophils-to-monocytes ratio（BMR） were 0.08±0.04, 0.11±0.06, and 0.08 ±0.04 respectively. There was a statistically significant difference between eCRS group and healthy control group, non-eCRS group（P<0.01）, while there was no statistically significant difference between non-eCRS group and healthy control group（P>0.05）. Basophil counts （r=0.185 5, P<0.05）, BLR（r=0.226 9, P<0.05）, BMR（r=0.228 1, P<0.01） in patients with CRS were positively correlated with Lund Makey score. In addition, basophils were also positively correlated with eosinophils（r=0.479 2, P<0.01）, lymphocytes（r=0.259 4, P<0.01）, and monocytes（r=0.256 4, P<0.01） in patients with CRS. Conclusion:The peripheral blood basophil count, BLR and BMR were significantly increased in eCRS, and were significantly positively correlated with Lund -Makey score. It has the potential to develop into disease biomarkers and new therapeutic targets of eCRS.

Cholestatic liver diseases (CLD) are a series of diseases due to impaired bile flow and accumulation of bile acid in the liver and/or systemic circulation caused by immune, genetic, and environmental factors. The pathogenesis of CLD remains unclear and CLD is difficult to treat. As a substitute for human diseases, animal models can provide a platform for exploring the etiology and pathogenesis of the disease and finding appropriate therapeutic targets. This article reviews the current research advances in the animal models of CLD.
