OBJECTIVE:Some studies have shown that physical exercise can effectively improve knee extensor strength and cardiorespiratory function in burn patients;some studies have also shown that physical exercise is not effective in improving respiratory function in burn patients.Improvement effects of physical exercise on physical functions(muscle function,walking function,cardiopulmonary function,and lean body mass)of burn patients were evaluated by a systematic evaluation and meta-analysis.METHODS:Based on databases including Web of Science,PubMed,Embase,Cochrane Library,CNKI,WanFang,and the Chinese Biomedical Database,literature on the improvement of physical function in burn patients through physical exercise was searched using subject headings and free terms.With muscle function,walking ability,cardiopulmonary function,and lean body mass as the primary outcome measures,a meta-analysis was conducted to compare the efficacy of physical exercise with traditional physical therapy or conventional care methods.RESULTS:A total of 38 papers were included,of which 26 papers were included in the meta-analysis,involving 1 658 patients.Meta-analysis results showed that:(1)Physical exercise significantly enhances the knee extensor strength of the dominant leg in burn patients(mean difference[MD]=8.34,95％confidence interval[CI]:6.95-9.72,P＜0.000 01),increases quadriceps strength,peak oxygen uptake,forced vital capacity and maximum ventilation volume in 1 second,and resting heart rate(standardized mean difference[SMD]=4.41,95％CI:2.52-6.30,P＜0.000 01;MD=4.91,95％CI:3.52-6.29,P＜0.000 01;MD=5.86,95％CI:0.09-11.63,P=0.05;MD=6.90,95％CI:2.93-10.87,P=0.000 7;MD=5.03,95％CI:1.45-8.61,P=0.006),and improves the 6-minute walking distance,gait parameters,and total lean body mass(MD=45.29,95％CI:24.7-65.89,P＜0.0001;SMD=7.84,95％CI:6.05-9.63,P＜0.000 01;MD=2.47,95％CI:2.01-2.93,P＜0.000 01).(2)The subgroup analysis results indicated that the improvement in knee extensor strength of the dominant leg may be better in children than in adults and better in the extra-heavy group than in the heavy group.Improvement in the 6-minute walking distance is better in children than in adults,and higher degree of burn indicates better improvement effects,with no difference from the control group for＜12 weeks.Peak oxygen uptake may be better in adults and severe burn groups than in children and moderate burn groups,resistance combined with aerobic exercise modalities may be better than aerobic exercise alone,and exercise duration＞60 minutes may be better than＜60 minutes.CONCLUSION:Physical activity is effective in improving physical function in burn patients,as evidenced by improvements in muscle strength,walking ability,cardiorespiratory fitness,and lean body mass.The quality of evidence recommended for all indicator results is moderate or below,with imprecision and inconsistency being the main factors for downgrading.Therefore,more high-quality randomized controlled trials are needed in the future to verify the reliability of the results.

Pulmonary hypertension (PH), marked by sustained elevation of pulmonary artery pressure, imposes a heavy burden on the right ventricle and may culminate in right heart failure. Its pathogenesis is multifaceted, encompassing endothelial dysfunction, vascular smooth muscle proliferation, inflammation, thrombosis, and genetic factors. Animal models serve as core tools for exploring PH mechanisms and therapies, each with unique strengths and limitations. The single-dose monocrotaline (MCT) model is one of the most commonly used experimental animal models of PH and is widely applied in mechanistic studies, drug screening, and efficacy evaluation; it offers simplicity and cost-effectiveness, can induce PH within a short period, yet its pathophysiology differs to some extent from human idiopathic PH. In contrast, the Sugen5416 combined with chronic hypoxia model better mimics PH progression by placing animals under hypoxic conditions to induce pulmonary vasoconstriction and vascular remodeling, but it requires a longer modelling time, and the degree of hypoxia has a substantial impact on experimental outcomes. Beyond these two commonly used modeling approaches, a variety of emerging techniques have been applied in PH research; gene-editing technologies enable precise investigation of specific gene functions in PH. Additionally, induced pluripotent stem cell-based 3D organoid technology allows for individualized modelling while preserving patients' genetic information for precise clinical translation. Each model or technology can simulate different aspects of the pathological processes of human PH, and their findings provide key insights into the nature of the disease and serve as an important platform for the development of novel therapeutic targets. This paper comprehensively describes various animal models and emerging technologies used in PH research, analyzing their characteristics, applications, and limitations, with the aim of providing experimental and technical support for the development of new therapeutic strategies and drugs.

ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， systemic immune-inflammation index （SII） and the severity of intrauterine adhesions （IUA）. MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions （TCRA） from December 2019 to March 2025. Based on the American Fertility Society （AFS） classification， patients were divided into mild （n=61）， moderate （n=225）， and severe （n=94） groups. NLR， PLR， and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR， PLR， and SII were significantly higher in the severe IUA group compared to the mild group （P<0.05）， with SII showing the strongest predictive ability （OR=1.004， P=0.001）. The number of intrauterine procedures was an independent risk factor （OR=1.27/level， P=0.016）. The predictive model ［Logit（P）=-0.676+0.241×operation times+0.004×SII］ effectively identified severe IUA cases. ConclusionInflammatory markers （particularly SII） are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

Objective:To explore the diagnostic value of serum soluble semaphorin 4D (sSema4D) and soluble CD40 ligand (sCD40L) in left ventricular hypertrophy (LVH) in patients with primary hypertension (EH).Methods:Eighty-four patients with EH combined with LVH admitted to Qingdao Hospital of Shandong First Medical University from December 2022 to December 2023 were prospectively selected as the study group, and 84 patients with EH and without LVH admitted to Qingdao Hospital of Shandong First Medical University during the same period were regarded as the control group. Enzyme linked immunosorbent assay was applied to detect the levels of sSema4D and sCD40L. Employing Pearson correlation coefficient, the study assessed the association between concentrations of sSema4D and sCD40L in serum and various echocardiographic measurements. A multivariate Logistic regression model was engaged to probe into the contributing factors for the development of LVH. ROC curve was plotted to analyze the diagnostic value of serum sSema4D and sCD40L for EH combined with LVH.Results:Serum sSema4D and sCD40L levels were significantly higher in the study group than in the control group: (8.56 ± 2.19) μg/L vs. (5.12 ± 1.43) μg/L, (4.02 ± 1.03) μg/L vs. (3.22 ± 0.98) μg/L, and the differences were statistically significant ( P<0.05). The duration of hypertension, LVEDD, IVSTD, LVPWT, and LVMI were significantly higher in the study group than in the control group: (7.33 ± 1.53) years vs. (4.26 ± 1.35) years, (50.28 ± 3.33) mm vs. (44.45 ± 3.76) mm, (11.64 ± 3.21) mm vs. (9.53 ± 2.89) mm, (12.45 ± 1.52) mm vs. (9.13 ± 0.98) mm, (126.11 ± 15.28) g/m 2 vs. (81.15 ± 11.31) g/m 2, and the differences were statistically significant ( P<0.05). According to Pearson correlation analysis, it was known that both serum sSema4D and sCD40L were positively correlated with LVEDD, IVSTD, LVPWT and LVMI ( r = 0.425 and 0.533, 0.612 and 0.436, 0.513 and 0.628, 0.589 and 0.618; P<0.05). Multivariate Logistic regression analysis showed that hypertension duration, LVEDD, IVSTD, LVPWT, LVMI, sSema4D, sCD40L were risk factors for LVH in EH patients ( P<0.05). According to the ROC curve, the AUC for diagnosing EH combined with LVH with serum sSema4D was 0.848, the AUC for diagnosing EH combined with LVH with serum sCD40L was 0.725, and the AUC for diagnosing EH combined with LVH with serum sCD40L was 0.888, the combination of sCD40L and sCD40L was superior to their respective individual diagnoses ( Z = 2.651 and 2.526, P<0.05). Conclusions:The serum levels of sSema4D and sCD40L in patients with EH combined with LVH are obviously elevated, which are influencing factors for the occurrence of EH combined with LVH. Combined testing of the two has high diagnostic value for EH combined with LVH.

Objective To investigate the diagnostic efficacies of serum cytokines and peripheral blood C-reactive protein(CRP)in tu-berculosis patients with concurrent other bacterial or fungal infections.Methods A total of 101 cases of pulmonary tuberculosis from Songjiang Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were enrolled in this study(n=101).Based on mi-crobiological culture of sputum/bronchoalveolar lavage fluid(BALF)combined with targeted next-generation sequencing(tNGS),they were divided into two groups:the infection group(n=37),comprising the patients with pulmonary tuberculosis combined with other bacterial or fungal infection,and the non-infection group(n=64),comprising the patients with pulmonary tuberculosis but without such combined infections.Additionally,45 healthy individuals undergoing physical examinations were included as the control group.Se-rum levels of cytokines,including interleukin-2(IL-2),soluble interleukin-2 receptors(sIL-2R),interleukin-6(IL-6),interferon-γ(IFN-γ)and tumor necrosis factor-α(TNF-α),were measured using chemiluminescent immunoassay.Clinical data and laboratory in-dicators,such as CRP were also collected from the patients with pulmonary tuberculosis.Mann-Whitney U test was used to screen the indicators with significant differences.Binary logistic regression analysis was performed to identify the factors associated with pulmonary tuberculosis co-infected with other bacterial and fungal infections.The diagnostic performance of these indicators was evaluated using re-ceiver operating characteristic(ROC)curves analysis.Results The levels of serum sIL-2R,IL-6,IFN-γ,and TNF-α in patients with tuberculosis were higher compared with the control group,while the IL-2 levels was lower with statistically significant differences(all P＜0.05).Compared with the non-infection group,infection group showed significantly elevated IL-2,sIL-2R,IL-6 and CRP lev-els(all P＜0.05).Binary logistic regression analysis indicated that male sex,history of previous tuberculosis,sIL-2R and CRP were all associated with bacterial or fungal co-infections in the patients with tuberculosis(all P＜0.05).ROC curve analysis indicates that com-bined detections of sIL-2R and CRP provided adequate discriminative performance for co-infection of tuberculosis complicated with oth-er bacterial or fungal co-infections,with an area under the curve(AUC)of 0.746(95%CI:0.650-0.843,P＜0.001),sensitivity of 81.1%,and specificity of 64.1%.Conclusion Male sex,history of previous tuberculosis,serum sIL-2R and CRP are independent predictive factors of other bacterial or fungal co-infections in the patients with pulmonary tuberculosis.The combined detection of sIL-2R and CRP may provide valuable information for identifying the co-infection of other bacteria or fungi.

OBJECTIVE To investigate the improvement effect and mechanism of desloratadine citrate disodium in mice with hypersensitivity pneumonitis(HP).METHODS Sixty mice were randomly divided into blank control group(normal saline),model group(normal saline),prednisone group(positive control,20 mg/kg)and desloratadine citrate disodium low-,medium-and high-dose groups(0.5,1,2 mg/kg),with 10 mice in each group.Except for the blank control group,mice in other groups were intraperitoneally injected with ovalbumin(OVA)and exposed to OVA inhalation to establish the HP model.On day 22 post-modeling,mice in each group were administered the corresponding drugs or normal saline,once a day,for 11 consecutive days.After the last administration,lung function and airway hyperreactivity were assessed.The levels of interleukin-1β(IL-1β),IL-4 and IL-6 in serum as well as the levels of IL-8,IL-13 and IL-17A in bronchoalveolar lavage fluid were determined.Pathological changes in lung tissue of mice were evaluated using Masson staining.Furthermore,the expressions of fibrosis-related proteins,including transforming growth factor β1(TGF-β1),type Ⅲ collagen(Col-Ⅲ)and fibronectin(FN)were determined in lung tissues.RESULTS Compared with the blank control group,the model group showed significant deterioration in lung function(P＜0.01),while airway resistance and serum levels of IL-1β,IL-4,IL-6 and the levels of IL-8,IL-13 and IL-17A in the bronchoalveolar lavage fluid were increased significantly(P＜0.01).The lung tissues exhibited alveolar collapse,atrophy,and structural disarray,along with the formation of extensive deposits of blue collagen fibers,the percentage of positive staining increased significantly(P＜0.01).Additionally,the expression levels of TGF-β1,Col-Ⅲ,and FN proteins in the lung tissues were also increased significantly(P＜0.01).After intervention with desloratadine citrate disodium,the pathological changes in the lung tissues of mice in each dosage group of desloratadine citrate disodium showed varying degrees of improvement,and most of the aforementioned indicator levels were significantly reversed(P＜0.05 or P＜0.01).CONCLUSIONS Desloratadine citrate disodium can improve the lung function and airway hyperreactivity of HP mice,inhibit the release of inflammatory factors in serum and bronchoalveolar lavage fluid,and reduce the deposition of collagen fibers.Its mechanism of action may be related to anti-inflammatory,immunomodulatory,and antifibrotic effects.
