ObjectiveTo investigate the characteristics and potential mechanisms of Luotong Xianrong Yin （LTXRY） in improving lung injury in rats with idiopathic pulmonary fibrosis （IPF） by regulating glycolysis. MethodsForty specific pathogen-free （SPF） Sprague-Dawley （SD） rats were randomly divided into a sham-operated group （10 mL·kg^-1）， model group （10 mL·kg^-1）， LTXRY group （15.18 g·kg^-1）， and nintedanib group （0.1 g·kg^-1）， with 10 rats in each group. The IPF rat model was established by intratracheal instillation of bleomycin. After 28 days of gavage intervention， pulmonary function was assessed. Lung pathological changes were observed by hematoxylin-eosin （HE） and Masson staining. Enzyme-linked immunosorbent assay （ELISA） was used to determine the levels of inflammatory factors， including tumor necrosis factor-α （TNF-α）， interleukin （IL）-1β， and IL-6， in lung tissue. Chemiluminescence assays were employed to detect lactate content and lactate dehydrogenase activity in lung tissue. Western blot was used to measure the protein expression of transforming growth factor-β₁ （TGF-β₁）， CollagenⅠ and CollagenⅢ to evaluate collagen deposition， as well as hexokinase 2 （HK2）， pyruvate kinase M2 （PKM2）， and 6-phosphofructo-2-kinase/fructose-2，6-bisphosphatase 3 （PFKFB3） to assess glycolysis levels. Network pharmacology was applied to analyze the potential targets and signaling pathways of LTXRY in IPF， and molecular docking was conducted to evaluate the binding energy between active components and potential targets. Western blot was further used to detect the expression of target- and pathway-related proteins. ResultsCompared with the sham-operated group， rats in the model group showed significantly increased main airway resistance （Rn） and respiratory system resistance （Rrs）， and significantly decreased respiratory system compliance （Crs）. Inflammatory infiltration and collagen deposition were observed in lung tissue， with significantly increased levels of TNF-α， IL-1β， and IL-6， as well as elevated protein expression of TGF-β₁， CollagenⅠ and CollagenⅢ. Lactate content， lactate dehydrogenase activity， and the protein expression of HK2， PKM2， and PFKFB3 in lung tissue were significantly increased. Network pharmacology analysis indicated that signal transducer and activator of transcription 3 （STAT3） was a key target of LTXRY in IPF， and hypoxia-inducible factor-1 （HIF-1） was a critical signaling pathway. The expression levels of phosphorylated STAT3 （p-STAT3） and HIF-1α in lung tissue were significantly higher than those in the sham-operated group. Compared with the model group， rats in the LTXRY group showed significantly decreased Rn and Rrs and significantly increased Crs. Lung inflammatory infiltration and collagen deposition were markedly alleviated， with significantly reduced levels of TNF-α， IL-1β， and IL-6， and decreased protein expression of TGF-β₁， CollagenⅠ and CollagenⅢ. Lactate content， lactate dehydrogenase activity， and the protein expression of HK2， PKM2， and PFKFB3 were significantly decreased， accompanied by markedly reduced expression of p-STAT3 and HIF-1α. ConclusionLTXRY alleviates lung tissue injury in IPF rats by regulating glycolysis mediated by the STAT3/HIF-1α signaling pathway.

BACKGROUND:Spondylolisthesis is a common disease,and there is a lack of effective drugs to treat it.There is still a need to further define the pathogenesis and screen out more suitable therapeutic targets for spondylolisthesis.Mendelian randomization analysis can be used to explore the drugable genes associated with spondylolisthesis and provide valuable guidance for the development of more effective and targeted therapeutic drugs.OBJECTIVE:To explore potential therapeutic targets and effective drugs for spondylolisthesis by means of pharmaceutically available genome-wide Mendelian randomization analysis.METHODS:Using the Finnish database,eQTLGen consortium,drug signature database,drug-gene interaction database,protein-protein interaction database,organic small molecule biological activity database and protein structure database,which contains genome and health information of half a million Finns,data on druggable genes were subjected to two-sample Mendelian randomization analysis and co-localization analysis with data from genome-wide association studies of spondylolisthesis to identify genes highly associated with spondylolisthesis.In addition,GO and KEGG enrichment analysis,protein network construction,drug prediction and molecular docking were performed to provide valuable guidance for the development of more effective and targeted therapeutic agents.RESULTS AND CONCLUSION:In this study,we identified 34 potential drug target genes that were significantly associated with spondylolisthesis,particularly the gene APOBEC3G.This gene showed a significant association with spondylolisthesis outcomes through Mendelian analysis and co-localization analysis,suggesting that APOBEC3G may be a priority therapeutic target.As for other potential mechanisms and drugs,we still need to conduct more in-depth research to determine their roles.This study used a database from a European population,which can be used as a reference for the study of population genetics in China.

The high comorbidity and heterogeneity of obsessive-compulsive disorder (OCD) underscore the importance of better understanding its transdiagnostic features. Intolerance of uncertainty (IU), a transdiagnostic negative psychological trait, has been consistently linked to a variety of psychiatric disorders, including OCD. IU is hierarchically structured, comprising general IU, inhibitory IU and prospective IU, each of them potentially relating differently to OCD symptom dimensions. For example, inhibitory IU has shown specific associations with procrastination behaviors. Neuroimaging studies indicate that OCD patients demonstrate abnormal neural activity within the fronto-limbic circuit and salience network, including anterior insula, amygdala and ventromedial prefrontal cortex, during IU-related psychological processes. This review synthesizes findings across three key areas: symptom presentation, neurobiological mechanisms and intervention strategies, aiming to clarify the role of IU in OCD. Furthermore, the potential of targeting IU therapeutically to complement first-line treatment is discussed, ultimately enhancing clinical intervention outcomes.

ObjectiveTo conduct a bibliometric visual analysis of studies on Enterococcus faecium， Staphylococcus aureus， Klebsiella pneumoniae， Acinetobacter baumannii， Pseudomonas aeruginosa and Enterobacter species （ESKAPE） in the past 10 years at home and abroad， and to analyze current research status and future research directions in this field based on the concept of “One health”. MethodsRelated literature on ESKAPE drug resistant bacteria from 2013 to 2022 was searched on CNKI and WoS， respectively. Furthermore， a metrological visualization analysis of authors， source of agencies， countries， and keywords was conducted by the CiteSpace 6.1.R6 software. ResultsA total of 2 991 pieces of Chinese-language and 24 497 pieces of English-language literature were included in this study. Although the number and growth rate of English-language publications were higher than those of Chinese-language publications， the number of English-language papers authored by Chinese scholars showed a significant upward trend. The level of collaboration between authors and institutions in Chinese-language publications was weaker than that in English-language publications. Overall， the country with the highest number of publications was the United States （6 623）， followed by China （3 776）. However， China’s annual publication volume （851） exceeded that of the United States （600） in 2022. China had collaborations with 25 countries， indicating good global cooperation， but its level of international cooperation was still slightly weaker than that of the United States. High-frequency keywords in Chinese-language literature mainly included drug resistance， nosocomial infection， and antibiotics， while high-frequency keywords in English-language literature included Staphylococcus aureus， Klebsiella pneumoniae， and methicillin-resistant. ConclusionCarbapenem-resistant Klebsiella pneumoniae， carbapenem-resistant Enterobacteriaceae， and "One health" are research hotspots. In the future， cross-sectoral and multi-regional collaboration should be deepened to strengthen the control of infections of important drug-resistant bacteria， and infection treatment strategies should be optimized as well.

Background At present, the practice of pulmonary rehabilitation for pneumoconiosis in China is in a primary stage. The basis for formulating an individualized comprehensive pulmonary rehabilitation plan is still insufficient, which is one of the factors limiting the development of community-level rehabilitation work. Objective To formulate an exercise prescription based on maximum heart rate measured by cardiopulmonary exercise test (CPET), conduct an individualized comprehensive pulmonary rehabilitation program with the exercise prescription for patients with stable pneumoconiosis, and evaluate its role in improving exercise endurance and quality of life, thus provide a basis for the application and promotion of pulmonary rehabilitation. Methods A total of 68 patients were recruited from the Occupational Disease Prevention Hospital of Jinneng Holding Coal Industry Group Co., Ltd. from April to August 2022 , and were divided into an intervention group and a control group by random number table method, with 34 cases in each group. All the pneumoconiosis patients participated in a baseline test. The control group was given routine drug treatment, while the intervention group received multidisciplinary comprehensive pulmonary rehabilitation treatment on the basis of routine drug treatment, including health education, breathing training, exercise training, nutrition guidance, psychological intervention, and sleep management, whose exercise intensity was determined according to the maximum heart rate provided by CPET. The rehabilitation training lasted for 24 weeks. Patients were evaluated at registration and the end of study respectively. CPET was used to measure peak oxygen uptake per kilogram (pVO₂/kg), anaerobic threshold (AT), carbon dioxide equivalent of ventilation (EqCO₂), maximum metabolic equivalent (METs), and maximum work (W_max). The modified British Medical Research Council Dyspnea Questionnaire (mMRC), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Pittsburgh Sleep Quality Index (PSQI), Chronic Obstructive Pulmonary Disease Assessment Test (CAT), and Short Form of Health Survey (SF-36) were used to evaluate the potential effect of the comprehensive pulmonary rehabilitation program. Results Among the included 68 patients, 63 patients were having complete data, then 31 cases were assigned in the control group and 32 cases in the interventional group. Before the intervention, there was no significant difference in pVO₂/kg, AT, EqCO₂, METs, or W_max between the two groups (P>0.05). At the end of the trail, the indicators like pVO₂/kg [(19.81±2.38) mL·(min·kg)⁻¹], AT [(14.48±2.33) mL·(min·kg)⁻¹], METs (5.64±0.69), and W_max [(85.25±14) W] of patients in the intervention group were all higher than those [(13.90±2.37) mL·(min·kg)⁻¹, (11.70±1.94) mL·(min kg)⁻¹, (3.97±0.70), and (61.77±14.72) W, respectively] in the control group (P<0.001); there was no significant difference in EqCO₂ between the two groups (P=0.083). Before the trial, there was no significant difference in mMRC, SAS, SDS, PSQI, or CAT scores between the two groups (P>0.05). At the end of the trail, the mMRC score (1.16±0.57), SAS score (27.93±2.12), SDS score (26.48±1.44), PSQI score (1.08±0.88), and CAT score (4.34±3.28) of patients in the intervention group were lower than those [(2.03±0.83), (35.87±6.91), (34.23±6.65), (5.37±3.03), and (13.87±7.53), respectively] in the control group (P<0.001). The SF-36 scores of bodily pain (94.13±10.72), general health (87.50±5.68), vitality (95.31±5.53), mental health (99.88±0.71), and health changes (74.22±4.42) in the intervention group were higher than those [(71.87±32.72), (65.81±15.55), (74.52±16.45), (86.97±16.56), and (29.84±13.50), respectively] in the control group (P<0.001), and no significant difference was found in social functioning and role emotional scores (P>0.05). Conclusion Comprehensive pulmonary rehabilitation can increase the oxygen intake and exercise endurance of pneumoconiosis patients, ameliorate dyspnea symptoms, elevate psychological state and sleep quality, and improve the quality of life.

Compared with the global average, the incidence rate of nasopharyngeal carcinoma (NPC) in China is higher, particularly in the southern regions where the mortality rate has remained persistently high. Nimotuzumab, a targeted therapy that acts on the epidermal growth factor receptor, has prompted continuous progress in NPC treatment. The combination of nimotuzumab with traditional radiotherapy and chemotherapy can enhance treatment efficacy, reduce adverse reactions, and improve patients’ quality of life. This article summarizes current research findings from this perspective to provide diagnostic and therapeutic strategies for NPC treatment.

Background Multi-slice spiral computerized tomography (MSCT) can be used as an auxiliary diagnosis of chest radiography in diagnosis of pneumoconiosis, but there are few studies on the correlations between interstitial images and stage classification of coal workers' pneumoconiosis in the existing literature. Objective To present MSCT imaging manifestations and distribution characteristics of coal workers' pneumoconiosis and complications, evaluate correlations between coal workers' pneumoconiosis stages and pulmonary interstitial lesions, and provide a reliable imaging diagnosis basis for pneumoconiosis interstitial lesions. Methods From June 2022 to June 2023, a total of 1002 patients with coal workers' pneumoconiosis confirmed by the pneumoconiosis diagnostic and identification group in the Department of Occupational Diseases of the Emergency General Hospital were enrolled. MSCT was used to observe the abnormal imaging manifestations of the lungs of coal workers' pneumoconiosis patients and the diseases of pulmonary fibrosis related to their own diseases (thickening of the interlobular septum, bronchial perivascular interstitial mass thickening, parenchymal banding, subpleural line, intralobular interstitial thickening, honeycomb, and subpleural interstitial thickening), the occurrence of coal workers' pneumoconiosis and complications (old tuberculosis, active tuberculosis, pneumonia, atelectasis, lung cancer, bronchiectasis), and the density, size, and location of pneumoconiosis nodules. Imaging data were analyzed and statistically processed. Results All 1002 patients were male, with an average age of (60.71±6.87) years and an average dust exposure time of (23.01±7.80) years. Among them, there were 470 patients with stage I, 422 patients with stage II, and 110 patients with stage III. There were significant differences in the distribution of thickening of the interlobular septum, bronchial perivascular interstitial mass thickening, parenchymal banding, intralobular interstitial thickening, subpleural interstitial thickening, and honeycomb across different stages (P<0.05). Statistically significant differences in p, q, and r subsets of round nodules were found in patients with pneumoconiosis at different stages (P<0.05). Observed nodule types included solid nodules, pure ground-glass shadow nodules, and partial solid nodules. There were statistically significant differences in pulmonary tuberculosis and bronchiectasis among different stages of coal workers' pneumoconiosis (P<0.05). There were statistically significant differences in interstitial shadows and patches combined with interstitial shadows among different stages of pneumoconiosis complicated with pneumonia (P<0.05). Conclusion MSCT provides images of the progression of coal workers' pneumoconiosis and have a certain relationship with the stages of coal workers' pneumoconiosis, which is conducive to the formulation of reasonable treatment plans in the early clinical stage. Therefore, in the diagnosis and treatment of pneumoconiosis, a great attention should be paid to the imaging technology of chest computerized tomography, especially the use of MSCT examination.

Background It is a research hotspot to study the changes of metabolites and metabolic pathways in the process of coal worker's pneumoconiosis (CWP) by metabonomics and to explore its pathogenesis. Objective To study the change of metabolites in bronchoalveolar lavage fluid (BALF) of patients with CWP and explore the metabolic regulation mechanism of the disease. Methods Patients with CWP who met the national diagnostic criteria according to Diagnosis of occupational pneumoconiosis (GBZ 70-2015) and underwent massive whole lung lavage were selected as the case group, and patients with tracheostenosis who underwent bronchoscopy were selected as the control group. BALF samples were collected from the cases and the controls. After filtering out large particles and mucus, the supernatant was stored in a −80 ℃ refrigerator. The samples were detected and analyzed by liquid chromatography-mass spectrometry after adding extraction solution, cold bath ultrasonication, and high-speed centrifugation, and the metabolic profiles and related data of CWP patients were obtained. The differential metabolites related to the occurrence and development of CWP were screened by multiple statistical analysis; furthermore, we searched the Kyoto Encyclopedia of Genes and Genomes (KEGG) database for potential metabolic pathways involved in the progression. Results There was no significant difference in the general conditions of the subjects, such as weight, height, age, and length of service among the stage I group, the stage II group, the stage III group, and the control group (P˃0.05). When comparing the CWP stage I group with the control group, 48 differential metabolites were screened out, among which 14 were up-regulated and 34 were down-regulated. A total of 66 differential metabolites were screened out between the patients with CWP stage II and the controls, 14 up-regulated and 52 down-regulated differential metabolites. Compared with the control group, 63 differential metabolites were screened out in the patients with CWP stage III, including 11 up-regulated and 52 down-regulated differential metabolites. There were 36 differential metabolites that may be related to the occurrence of CWP, among which 11 differential metabolites were up-regulated, and 25 were down-regulated. Four significant differential metabolic pathways were identified through KEGG database query: linoleic acid metabolic pathway, alanine metabolic pathway, sphingolipid metabolic pathway, and glycerophospholipid metabolic pathway. Conclusion The metabolomic study of BALF show that there are 36 different metabolites in the occurrence and development of CWP, mainly associating with linoleic acid metabolism, alanine metabolism, sphingolipid metabolism, and glycerophospholipid metabolism pathways.
