RESUMEN

Background: Posttraumatic growth has a positive impact on patients diagnosed with acute coronary syndrome (ACS). Patients with acute coronary syndrome in China report low to moderate levels of posttraumatic growth. Additionally, there is a dearth of research exploring the associations between resilience, social support, and posttraumatic growth in this specific patient population. Objective: This study examined whether resilience serves as a mediator between social support and posttraumatic growth in patients with acute coronary syndrome who had been discharged for 1 to 6 months and were being followed up in clinics. Methods: A descriptive correlational study design was utilized. A systematic sampling technique was used to recruit 121 patients with acute coronary syndrome who had been discharged for 1 to 6 months from cardiovascular clinics of a tertiary care hospital in Jiangsu Province, China. The research instruments included the demographic characteristics questionnaire, the Connor-Davidson Resilience Scale, the Multidimensional Scale of Perceived Social Support, and the Posttraumatic Growth Inventory. The data were collected between August 2022 and November 2022 and were analyzed using descriptive statistics and regression analyses to determine the mediating effects. Results: The level of posttraumatic growth among patients with acute coronary syndrome attending follow-up clinic visits was moderate (Mean = 60.58, SD = 14.13). Resilience had a direct and positive impact on posttraumatic growth (ß = 0.361, p <0.001). Moreover, resilience fully mediated the relationship between social support and posttraumatic growth (indirect effect = 0.203, 95% CI [0.076, 0.331]; direct effect = 0.162, p = 0.101). Conclusion: Patients with acute coronary syndrome in China experience moderate posttraumatic growth after discharge. Resilience mediates the relationship between social support and posttraumatic growth. Therefore, nursing interventions focusing on promoting social support and resilience should be developed to encourage posttraumatic growth in patients with acute coronary syndrome.

RESUMEN

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal fibrotic disease. Recent studies have highlighted the persistence of an intermediate state of alveolar stem cells in IPF lungs. In this study, we discovered a close correlation between the distribution pattern of intermediate alveolar stem cells and the progression of fibrotic changes. We showed that amphiregulin (AREG) expression is significantly elevated in intermediate alveolar stem cells of mouse fibrotic lungs and IPF patients. High levels of serum AREG correlate significantly with profound deteriorations in lung function in IPF patients. We demonstrated that AREG in alveolar stem cells is both required and sufficient for activating EGFR in fibroblasts, thereby driving lung fibrosis. Moreover, pharmacological inhibition of AREG using a neutralizing antibody effectively blocked the initiation and progression of lung fibrosis in mice. Our study underscores the therapeutic potential of anti-AREG antibodies in attenuating IPF progression, offering a promising strategy for treating fibrotic diseases.

RESUMEN

BACKGROUND: Non-small-cell lung cancer (NSCLC) often presents at later stages, typically associated with poor prognosis. Autophagy genes play a role in the progression of tumors. This study investigated the clinical relevance, prognostic value, and biological significance of RBBP4 in NSCLC. METHODS: We assessed RBBP4 expression using the GSE30219 and TCGA NSCLC datasets and NSCLC cells, exploring its links with clinical outcomes, tumor immunity, and autophagy genes through bioinformatics analysis after transcriptome sequencing of RBBP4-knockdown and control PC9 cells. We identified differentially expressed genes (DEGs) and conducted Gene Ontology, Kyoto Encyclopedia of Genes and Genomes pathway enrichment, and protein-protein interaction network analyses. The significance of autophagy-related DEGs was evaluated for diagnosis and prognosis using the GSE30219 dataset. Experiments both in vivo and in vitro explored the biological mechanisms behind RBBP4-mediated autophagic cell death in NSCLC. RESULTS: RBBP4 overexpression in NSCLC correlates with a poorer prognosis. Eighteen types of immune cell were significantly enriched in cultures that had low RBBP4 expression compared high expression. DEGs associated with RBBP4 are enriched in autophagy pathways. Transcriptomic profiling of the PC9 cell line identified autophagy-related DEGs associated with RBBP4 that exhibited differential expression in NSCLC, suggesting prognostic applications. In vitro experiments demonstrated that RBBP4 knockdown induced autophagy and apoptosis in PC9 cells, promoting cell death, which was inhibited by 3-MA. In vivo, targeted siRNA against RBBP4 significantly reduced tumor development in PC9 cell-injected nude mice, elevating autophagy-related protein levels and inducing apoptosis and necrosis in tumor tissues. CONCLUSION: In NSCLC, RBBP4 upregulation correlates with poor prognosis and altered immunity. Its knockdown induces autophagic cell death in NSCLC cells. These results indicate RBBP4 as a potential NSCLC diagnostic marker and its autophagy modulation as a prospective therapeutic target.

RESUMEN

Skin is the first defense barrier of the human body, which can resist the invasion of external dust, microorganisms and other pollutants, and ensure that the human body maintains the homeostasis of the internal environment. Once the skin is damaged, the health threat to the human body will increase. Wound repair and the human internal environment are a dynamic process. How to effectively accelerate the healing of wounds without affecting the internal environment of the human body and guarantee that the repaired tissue retains its original function as much as possible has become a research hotspot. With the advancement of technology, researchers have combined new technologies to develop and prepare various types of materials for wound healing. This article will introduce the wound repair materials developed and prepared in recent years from three types: nanofibers, composite hydrogels, and other new materials. The paper aims to provide reference for researchers in related fields to develop and prepare multifunctional materials. This may be helpful to design more ideal materials for clinical application, and then achieve better wound healing and regeneration effects.

RESUMEN

OBJECTIVE: To determine the effectiveness of exercise intervention on postural balance, gait parameters, and muscle strength in children with cerebral palsy by quantifying the information from randomized controlled trials (RCTs). METHODS: We conducted a systematical search for RCTs from the databases, including PubMed, ISI Web of Science, and Scopus using a between-group design involving children with cerebral palsy and assessing the effect of exercise intervention on postural balance, gait parameters, and muscle strength. The specified inclusion criteria were determined by the PICOS tool. The outcomes of included studies were evaluated by meta-analysis, and subgroup and sensitivity analyses were conducted to analyze the observed heterogeneities using Review Manager 5.4 and Stata version 18.0. The revised Cochrane risk of bias tool for randomized trials (RoB 2) was used to evaluate the risk of bias and quality of the included studies. RESULTS: Twenty-four studies were included in this meta-analysis, with 579 children with cerebral palsy. Exercise intervention showed a statistically significant favorable effect on gross motor function (SMD = 0.32; 95%CI [0.03 to 0.61]; I2 = 16%), anteroposterior stability index (SMD = -0.93; 95%CI [-1.69 to -0.18]; I2 = 80%), and mediolateral stability index (SMD = -0.60; 95%CI [-1.16 to -0.03]; I2 = 73%) compared to control group among children with cerebral palsy. None of the above meta-analyses exhibited publication bias, as indicated by Egger's test with p-values greater than 0.05 for all. CONCLUSIONS: Exercise is effective in improving gross motor function and balance in children with cerebral palsy. Due to the lack of studies examining the efficacy of each exercise type, we are unable to provide definitive training recommendations.

RESUMEN

BACKGROUND: Colorectal cancer is the third most common malignancy worldwide and is one of the leading causes of cancer-related mortality. Ubiquitin-specific peptidase 18 (USP18) protein has been reported to exert different tumor-related effects in distinct tumor types. Here, we initially investigated the expression and signaling pathways of USP18 in colon adenocarcinoma (COAD). METHODS: A quantitative real-time PCR was conducted to evaluate the mRNA level of USP18 in cultured cells. Immunohistochemical staining was used to explore the protein expression of USP18 in clinical COAD samples. Specific knockdown was achieved by transient transfection of small interfering RNAs into SW480 and HT29 cells using Lipo3000. Cell conting kit-8 assay, transwell assay and matrigel-transwell assays were conducted to evaluate proliferation, migration and invasion capacities, respectively. Western blotting was performed to analyze downstream signaling pathways. A chi-squared test and univariate and multivariate analyses were used to evaluate the clinical data. Xenografts from mice model were assessed to validate the in vitro findings. RESULTS: Higher USP18 level was identified in COAD tissues and was positively correlated with advanced tumor stage. High USP18 protein expression indicated poorer prognosis of COAD patients. Silencing USP18 suppressed COAD cell proliferation and invasion via destabilizing extracellular signal-regulated kinase (ERK) protein and suppressing ERK downstream pathways. Simultaneously silencing interferon-stimulated gene 15 (ISG15) with USP18 can partially rescue the tumor cell viability, indicating its involvement in USP18 signaling. The oncogenic effects of USP18 were also confirmed in mice models. CONCLUSIONS: USP18 plays oncogenic effects in colon adenocarcinoma via ISG15-ERK pathways. High USP18 expression indicates poor clinical outcomes for colon adenocarcinoma patients.

RESUMEN

DaiDai fruit, a medicinal and edible plant fruit, is abundant in biologically active compounds and has a long history of use in traditional Chinese medicine. This research focuses on utilizing fermentation to develop a functional DaiDai fruit fermentation broth. Lactobacillus, Bacillus subtilis and Saccharomyces cerevisiae were employed in the fermentation process. By conducting screenings of bacterial strains, single factor experiments, and response surface methodology, the total flavonoids, polysaccharides, polyphenols, and 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH) free radical scavenging rate were used as the index for selection, ultimately identifying Lactobacillus L-13 as the optimal fermentation strain. The optimal fermentation conditions were determined to be a time of 108 h, a temperature of 43.6°C, and a solid-liquid ratio of 1:15.157 (w/v). Under these conditions, the total flavonoid content reached 412.01 mg/g, representing a 36.71% increase compared to conventional extraction methods. The contents of polysaccharides and polyphenols and the DPPH scavenging rate were also increased. The fermentation broth of DaiDai fruit exhibited inhibitory effects on tyrosinase and melanin production in mouse melanoma cells B16-F10 induced by α-MSH and anti-inflammatory properties in a zebrafish inflammation model. These indicate that the DaiDai fruit fermentation broth possesses anti-melanoma, whitening, and anti-inflammatory properties, showcasing significant potential for applications in medicine, cosmetics, and other industries.

RESUMEN

Background: The purpose of this study was to explore the relationship between infertility-related stress and dyadic coping with quality of life (QoL) in couples with infertility issues, and verify gender differences and dyadic interactions in the associations between them. Methods: This cross-sectional study included 340 couples who were recruited from the First Affiliated Hospital of Lanzhou University between March 2022 and November 2022. The Fertility Problem Inventory, Dyadic Coping Inventory and FertiQoL were used to measure infertility-related stress, dyadic coping and QoL. The Actor-Partner Interdependence Model was used to analyze the effects of infertility-related stress and dyadic coping on the couple's own QoL (actor effect) as well as on their partner's QoL (partner effect). Results: Female patients perceived significantly lower levels of QoL and dyadic coping than those of husbands. There was no statistically significant difference in the infertility-related stress between wives and husbands. Husbands' infertility-related stress had actor and partner effects on their own and their wives' QoL, while wives' infertility-related stress only had an actor effect on their own QoL. Husbands' dyadic coping had both actor effect and partner effects on their own and their wives' QoL, meanwhile wives' dyadic coping had both actor effect and partner effects on their own and their husbands' QoL. Conclusion: Husbands' QoL was impacted by their own infertility-related stress, dyadic coping and their wives' dyadic coping. Whereas wives' QoL was influenced by infertility-related stress and dyadic coping from both their own and their spouses. Therefore, elevating the level of dyadic coping may contribute to improving QoL for both husbands and wives. Moreover, enhancing the ability to cope with infertility-related stress might be useful for husbands and indirectly contribute to wives' QoL.

RESUMEN

Coronary microcirculation dysfunction (CMD) is one of the main causes of cardiovascular disease. Traditional treatment methods lack specificity, making it difficult to fully consider the differences in patient conditions and achieve effective treatment and intervention. The complexity and diversity of CMD require more standardized diagnosis and treatment plans to clarify the best treatment strategy and long-term outcomes. The existing treatment measures mainly focus on symptom management, including medication treatment, lifestyle intervention, and psychological therapy. However, the efficacy of these methods is not consistent for all patients, and the long-term efficacy is not yet clear. GSEA is a bioinformatics method used to interpret gene expression data, particularly for identifying the enrichment of predefined gene sets in gene expression data. In order to achieve personalized treatment and improve the quality and effectiveness of interventions, this article combined GSEA (Gene Set Enrichment Analysis) technology to conduct in-depth research on potential drug targets and their interaction networks in coronary microcirculation dysfunctions. This article first utilized the Coremine medical database, GeneCards, and DrugBank public databases to collect gene data. Then, filtering methods were used to preprocess the data, and GSEA was used to analyze the preprocessed gene expression data to identify and calculate pathways and enrichment scores related to CMD. Finally, protein sequence features were extracted through the calculation of autocorrelation features. To verify the effectiveness of GSEA, this article conducted experimental analysis from four aspects: precision, receiver operating characteristic (ROC) curve, correlation, and potential drug targets, and compared them with Gene Regulatory Networks (GRN) and Random Forest (RF) methods. The results showed that compared to the GRN and RF methods, the average precision of GSEA improved by 0.11. The conclusion indicated that GSEA helped identify and explore potential drug targets and their interaction networks, providing new ideas for personalized quality of CMD.

RESUMEN

Prevention of subsequent fracture is a major public health challenge in the field of osteoporosis prevention and treatment, and older women are at high risk for osteoporotic fractures. This study aimed to examine factors associated with subsequent fracture in older Chinese women with osteoporosis. We collected data on 9212 older female patients with osteoporotic fractures from 580 medical institutions in 31 provinces of China. Higher odds of subsequent fractures were associated with age of 70-79 years (OR 1.218, 95% CI 1.049-1.414), age ≥ 80 (OR 1.455, 95% CI 1.222-1.732), index fracture site was vertebrae (OR 1.472, 95% CI 1.194-1.815) and hip (OR 1.286, 95% CI 1.041-1.590), index fracture caused by fall (OR 1.822, 95% CI 1.281-2.591), strain (OR 1.587, 95% CI 1.178-2.139), no inducement (OR 1.541, 95% CI 1.043-2.277), and assessed as high risk of fracture (OR 1.865, 95% CI 1.439-2.416), BMD T-score ≤ -2.5 (OR 1.725, 95% CI 1.440-2.067), history of surgery (OR 3.941, 95% CI 3.475-4.471) and trauma (OR 8.075, 95% CI 6.941-9.395). Low risk of fall (OR 0.681, 95% CI 0.513-0.904), use of anti-osteoporosis medication (AOM, OR 0.801, 95% CI 0.693-0.926), and women who had received fall prevention health education (OR 0.583, 95% CI 0.465-0.730) associated with lower risk. The areas under the curve of the prediction model was 0.818. The sensitivity was 67.0% and the specificity was 82.0%. The prediction model showed a good ability to predict the risk of subsequent fracture in older women with osteoporotic fractures and are suitable for early self-measurement which may benefit post-fracture management.

RESUMEN

NASH (non-alcoholic steatohepatitis) is a severe liver disease characterized by hepatic chronic inflammation that can be associated with the gut microbiota. In this study, we explored the therapeutic effect of Gynostemma pentaphyllum extract (GPE), a Chinese herbal extract, on methionine- and choline-deficient (MCD) diet-induced NASH mice. Based on the peak area, the top ten compounds in GPE were hydroxylinolenic acid, rutin, hydroxylinoleic acid, vanillic acid, methyl vanillate, quercetin, pheophorbide A, protocatechuic acid, aurantiamide acetate, and iso-rhamnetin. We found that four weeks of GPE treatment alleviated hepatic confluent zone inflammation, hepatocyte lipid accumulation, and lipid peroxidation in the mouse model. According to the 16S rRNA gene V3-V4 region sequencing of the colonic contents, the gut microbiota structure of the mice was significantly changed after GPE supplementation. Especially, GPE enriched the abundance of potentially beneficial bacteria such as Akkerrmansia and decreased the abundance of opportunistic pathogens such as Klebsiella. Moreover, RNA sequencing revealed that the GPE group showed an anti-inflammatory liver characterized by the repression of the NF-kappa B signaling pathway compared with the MCD group. Ingenuity Pathway Analysis (IPA) also showed that GPE downregulated the pathogen-induced cytokine storm pathway, which was associated with inflammation. A high dose of GPE (HGPE) significantly downregulated the expression levels of the tumor necrosis factor-α (TNF-α), myeloid differentiation factor 88 (Myd88), cluster of differentiation 14 (CD14), and Toll-like receptor 4 (TLR4) genes, as verified by real-time quantitative PCR (RT-qPCR). Our results suggested that the therapeutic potential of GPE for NASH mice may be related to improvements in the intestinal microenvironment and a reduction in liver inflammation.

RESUMEN

Background: Fibrosing mediastinitis (FM) secondary to atypical sarcoidosis (atypical presentation of sarcoidosis) is rarely reported at home and abroad. Its clinical manifestations represent a lack of specificity, and the initial diagnosis is frequently difficult. In particular, this case has multiple pulmonary nodules with mediastinal lymph node enlargement and bilateral pleural effusion, and pulmonary fibrosis still exists after treatment, which is inconsistent with any clinical stage of pulmonary sarcoidosis, further increasing the diagnostic difficulty. We retrospectively analyzed the clinical data of a case of FM secondary to atypical sarcoidosis diagnosed by endobronchial ultrasound-guided cautery-assisted transbronchial mediastinal cryobiopsy (EBUS-CA-TBMCB) in Chongqing University Fuling Hospital, to improve clinicians' attention to FM and understand that EBUS-CA-TBMCB remains an effective way of etiological diagnosis. Case Description: A 70-year-old man was hospitalized with cough and dyspnea for two months. After admission, through chest computed tomography (CT), ultrasound guided bilateral lung biopsy, left parietal pleural biopsy, and EBUS-CA-TBMCB, the final diagnosis was atypical sarcoidosis secondary FM. After taking glucocorticoid orally, the patient's condition improved significantly, and was discharged from the hospital. We continued following up outside the hospital, and the patient's condition was further improved. Conclusions: The diagnosis of FM is mainly based on typical imaging manifestations. When the contrast-enhanced chest CT finds localized or diffuse soft tissue density shadows around the mediastinum and pulmonary hilum with an irregular shape, with or without calcification, particular attention should be paid to exclude FM. EBUS-CA-TBMCB, as an improved minimally invasive method, can obtain enough tissue samples for pathological diagnosis, which may be the effective biopsy method for the etiology of FM to avoid missed diagnosis and misdiagnosis in the future.

RESUMEN

As the main challenge of dental healthcare, oral infectious diseases are highly associated with the colonization of pathogenic microbes. However, current antibacterial treatments in the field of stomatology still lack a facile, safe, and universal approach. Herein, we report the controllable synthesis of copper aluminum-layered double hydroxides (CuAl-LDHs) with high Fenton-like catalytic activity, which can be utilized in the treatment of oral infectious diseases with negligible side effects. Our strategy can efficiently avoid the unwanted doping of other divalent metal ions in the synthesis of Cu-contained LDHs and result in the formation of binary CuAl-LDHs with high crystallinity and purity. Evidenced by experimental and theoretical results, CuAl-LDHs exhibit excellent catalytic ability toward the ·OH generation in the presence of H2O2 and hold strong affinity toward bacteria, endowing them with great catalytic sterilization against both Gram-positive and Gram-negative bacteria. As expected, these CuAl-LDHs provide outstanding treatments for mucosal infection and periodontitis by promoting wound healing and remodeling of the periodontal microenvironment. Moreover, toxicity investigation demonstrates the overall safety. Accordingly, the current study not only provides a convenient and economic strategy for treating oral infectious diseases but also extends the development of novel LDH-based Fenton or Fenton-like antibacterial reagents for further biomedical applications.

RESUMEN

Magnetic skyrmions are topologically protected, nanoscale whirls of the spin configuration that tend to form hexagonally ordered arrays. As a topologically non-trivial structure, the nucleation and annihilation of the skyrmion, as well as the interaction between skyrmions, varies from conventional magnetic systems. Recent works have suggested that the ordering kinetics in these materials occur over millisecond or longer timescales, which is unusually slow for magnetic dynamics. The current work investigates the skyrmion ordering kinetics, particularly during lattice formation and destruction, using time-resolved small angle neutron scattering (TR-SANS). Evaluating the time-resolved structure and intensity of the neutron diffraction pattern reveals the evolving real-space structure of the skyrmion lattice and the timeframe of the formation. Measurements were performed on three prototypical skyrmion materials: MnSi, (Fe,Co)Si, and Cu2OSeO3. To probe lattice formation and destruction kinetics, the systems were prepared in the stable skyrmion state, and then a square-wave magnetic field modulation was applied. The measurements show that the skyrmions quickly form ordered domains, with a significant distribution in lattice parameters, which then converge to the final structure; the results confirm the slow kinetics, with formation times between 10 ms and 99 ms. Comparisons are made between the measured formation times and the fundamental material properties, suggesting the ordering temperature, saturation magnetization and magnetocrystalline anisotropy may be driving the timeframes. Micromagnetic simulations were also performed and support a scaling of the kinetics with sample volume, a behavior which is caused by the reconciling of misaligned domains.

RESUMEN

BACKGROUND AND AIM: The study aims to introduce a novel indicator, effective withdrawal time (WTS), which measures the time spent actively searching for suspicious lesions during colonoscopy and to compare WTS and the conventional withdrawal time (WT). METHODS: Colonoscopy video data from 472 patients across two hospitals were retrospectively analyzed. WTS was computed through a combination of artificial intelligence (AI) and manual verification. The results obtained through WTS were compared with those generated by the AI system. Patients were categorized into four groups based on the presence of polyps and whether resections or biopsies were performed. Bland Altman plots were utilized to compare AI-computed WTS with manually verified WTS. Scatterplots were used to illustrate WTS within the four groups, among different hospitals, and across various physicians. A parallel box plot was employed to depict the proportions of WTS relative to WT within each of the four groups. RESULTS: The study included 472 patients, with a median age of 55 years, and 57.8% were male. A significant correlation with manually verified WTS (r = 0.918) was observed in AI-computed WTS. Significant differences in WTS/WT among the four groups were revealed by the parallel box plot (P < 0.001). The group with no detected polyps had the highest WTS/WT, with a median of 0.69 (interquartile range: 0.40, 0.97). WTS patterns were found to be varied between the two hospitals and among senior and junior physicians. CONCLUSIONS: A promising alternative to traditional WT for quality control and training assessment in colonoscopy is offered by AI-assisted computation of WTS.

RESUMEN

Histone chaperones serve a pivotal role in maintaining human physiological processes. They interact with histones in a stable manner, ensuring the accurate and efficient execution of DNA replication, repair and transcription. Retinoblastoma binding protein (RBBP)4 and RBBP7 represent a crucial pair of histone chaperones, which not only govern the molecular behavior of histones H3 and H4, but also participate in the functions of several protein complexes, such as polycomb repressive complex 2 and nucleosome remodeling and deacetylase, thereby regulating the cell cycle, histone modifications, DNA damage and cell fate. A strong association has been indicated between RBBP4/7 and some major human diseases, such as cancer, age­related memory loss and infectious diseases. The present review assesses the molecular mechanisms of RBBP4/7 in regulating cellular biological processes, and focuses on the variations in RBBP4/7 expression and their potential mechanisms in various human diseases, thus providing new insights for their diagnosis and treatment.

RESUMEN

Introduction: The primary treatment for non-alcoholic fatty liver disease (NAFLD) is modifying lifestyle through dietary or exercise interventions. In recent decades, it has received increasing attention. However, the lack of bibliometric analysis has posed a challenge for researchers seeking to understand the overall trends in this field. Methods: As of February 3rd, 2024, 876 articles on treating NAFLD through diet or exercise therapy from 2013 to 2023 had been retrieved. Two software tools, VOSviewer and CiteSpace, were utilized to analyze the growth of publications, countries, institutions, authors, journals, citations, and keywords. Additionally, the keywords with strong citation burstiness were identified to determine the changes and future trends of research hotspots in this field. Results: China had the highest number of articles, followed by the United States and South Korea. Yonsei University and Nutrients were the institutions and journals with the most significant contributions. Professor Younossi Zobair M, from the United States, is the most prolific author in this field. Through analyzing the keywords, three research hotspots were identified: research on the pathogenesis of NAFLD, research on the treatment modalities of NAFLD, and research on the risk factors and diagnosis methods of NAFLD. In recent years, the research emphasis in this field has changed, suggesting that future research will focus on two frontier keywords: "oxidative stress" and "aerobic capacity." Conclusion: In the past eleven years, the attention in this field was still rising, and the authors, journals, countries and so on had formed a considerable cooperative relationship. There were also many highly influential and productive researchers in this field. It is speculated that new research will continue around "aerobic exercise" and "oxidative stress" in the future.

RESUMEN

Non-alcoholic fatty liver disease (NAFLD) is usually associated with obesity. However, it is crucial to recognize that NAFLD can also occur in lean individuals, which is frequently overlooked. Without an approved pharmacological therapy for lean NAFLD, we aimed to investigate whether the Ganjianglingzhu (GJLZ) decoction, a representative traditional Chinese medicine (TCM), protects against lean NAFLD and explore the potential mechanism underlying these protective effects. The mouse model of lean NAFLD was established with a methionine-choline-deficient (MCD) diet in male C57BL/6 mice to be compared with the control group fed the methionine-choline-sufficient (MCS) diet. After four weeks, physiological saline, a low dose of GJLZ decoction (GL), or a high dose of GJLZ decoction (GH) was administered daily by gavage to the MCD group; the MCS group was given physiological saline by gavage. Untargeted metabolomics techniques were used to explore further the potential mechanism of the effects of GJLZ on lean NAFLD. Different doses of GJLZ decoction were able to ameliorate steatosis, inflammation, fibrosis, and oxidative stress in the liver; GL performed a better effect on lean NAFLD. In addition, 78 candidate differential metabolites were screened and identified. Combined with metabolite pathway enrichment analysis, GL was capable of regulating the glucose and lipid metabolite pathway in lean NAFLD and regulating the glycerophospholipid metabolism by altering the levels of sn-3-O-(geranylgeranyl)glycerol 1-phosphate and lysoPC(P-18:0/0:0). GJLZ may protect against the development of lean NAFLD by regulating glucose and lipid metabolism, inhibiting the levels of sn-3-O-(geranylgeranyl)glycerol 1-phosphate and lysoPC(P-18:0/0:0) in glycerophospholipid metabolism.

RESUMEN

Context: Due to the different effects of various drugs and the lack of authoritative and unified guidelines in clinical practice, the choice of therapeutic drugs for pulmonary tuberculosis (TB) remains controversial. Rifampicin, levofloxacin, and isoniazid are all anti-TB drugs. However, no comparative studies of the treatment effects of rifampicin + levofloxacin and rifampicin + isoniazid have occurred. Objective: The study intended to analyze the therapeutic effects of rifampicin + levofloxacin compared to rifampicin + isoniazid in the treatment of pulmonary TB to provide a clinical reference, which could provide new references for future clinical treatment of the disease. Design: The research team conducted a prospective controlled study. Setting: The study took place at Zibo Zhoucun District People's Hospital in Zibo, China. Participants: Participants were 100 patients with pulmonary TB admitted to the hospital between March 2021 and December 2022. Interventions: The research team assigned participants to one of two groups: (1) the intervention group, with 56 participants who received rifampicin + levofloxacin therapy, and (2) the control group, with 44 participants who received rifampicin + isoniazid. Outcome Measures: The research team measured: (1) clinical efficacy, (2) incidence of adverse reactions, (3) changes in inflammatory factors, (4) changes in immunoglobulins (Igs), and (5) changes in T lymphocyte subsets. Results: The intervention group's total effective rate for treatment was significantly higher than that of the control group (P = .049). However, no significant difference existed between the groups in the incidence of adverse reactions (P > .05). Postintervention, the intervention group's inflammatory factors-IL-6, TNF-α, hs-CRP, and ß-EP-were significantly lower and its immunoglobulins (Igs) G/A/M (IgG/A/M) were significantly higher than those of the control group (P < .05). In addition, the intervention group's T lymphocyte subpopulations of CD3+ and CD4+ and CD4+/CD8+ were significantly higher and CD8+ was significantly lower than those in the control group (P < .05). In other words, the intervention group had a better immune function. Conclusions: Compared with rifampicin + isoniazid, rifampicin + levofloxacin had a better clinical effect in the treatment of pulmonary TB and could effectively regulate patients' immune functions and inhibit inflammatory reactions. The current research team recommends that rifampicin + levofloxacin become the preferred treatment for pulmonary TB in the absence of a drug allergy.
