RESUMEN

SUMMARY: A Study on Relationship between Single-Slice Hounsfield Unit(HU) value of the Chinese proximal humerus and Bone Mineral Density(BMD) Using Routine Chest CT and Dual-energy X-ray Absorptiometry(DEXA) was performed. Data were collected from 240 individuals who underwent DEXA and routine chest CT scans (including full images of the proximal humerus) on the same day at 967 Hospitals between January 2019 and December 2021. The method of measuring single-slice HU values of the proximal humerus on routine chest CT scans exhibited high reliability and repeatability (intraclass correlation coefficient > 0.961, P < 0.001). A strong positive correlation was observed between single-slice HU values of the proximal humerus and DEXA results, with the 20-mm HU value demonstrating the highest correlation. Across different BMI groups, the Area Under Curve (AUC) for the 20-mm HU value was consistently the largest (AUC=0.701- 0.813, P< 0.05). Therefore, the 20-mm HU value can be considered a reliable reference for the opportunistic screening of low BMD, with reference values of -4HU for underweight individuals, -13HU for normal weight individuals, -7HU for overweight individuals, and -16HU for obese individuals. Values below these thresholds indicate a risk of low BMD. This study enriches the Chinese BMD data and offers a swift and effective approach for opportunistically screening low BMD.


Se realizó un estudio sobre la relación entre el valor de la Unidad Hounsfield (HU) de corte único del húmero proximal chino y la densidad mineral ósea (DMO) mediante TC de tórax de rutina y absorciometría de rayos X de energía dual (DEXA). Se recopilaron datos de 240 personas que se sometieron a DEXA y tomografías computarizadas de rutina de tórax (incluidas imágenes completas del húmero proximal) el mismo día en 967 hospitales entre enero de 2019 y diciembre de 2021. El método para medir los valores de HU de un solo corte del húmero proximal en las tomografías computarizadas de tórax mostraron alta confiabilidad y repetibilidad (coeficiente de correlación intraclase > 0,961, P < 0,001). Se observó una fuerte correlación positiva entre los valores de HU de un solo corte del húmero proximal y los resultados de DEXA, demostrando el valor de HU de 20 mm la correlación más alta. En diferentes grupos de IMC, el área bajo la curva (AUC) para el valor HU de 20 mm fue consistentemente el más grande (AUC = 0,701-0,813, P <0,05). Por lo tanto, el valor de HU de 20 mm puede considerarse una referencia fiable para el cribado oportunista de DMO baja, con valores de referencia de -4 HU para personas con bajo peso, -13 HU para personas con peso normal, -7 HU para personas con sobrepeso y -16 HU para personas obesas. Los valores por debajo de estos umbrales indican un riesgo de DMO baja. Este estudio es un aporte para los datos chinos sobre la DMO y ofrece un enfoque rápido y eficaz para detectar de forma oportunista la DMO baja.

RESUMEN

While the Internet has brought convenience and speed to human life, it has also led to frequent privacy violations. In the context of epidemiological investigations and information disclosure regarding confirmed Covid-19 patients, many individuals have utilized the Internet as a means to disseminate information and engage in cyber manhunts, resulting in breaches of privacy for those involved. This phenomenon is particularly prevalent within the realm of the Internet, where the boundaries of privacy invasion become blurred. Various types of privacy infringements, both active and passive negligence, are evident on social networking platforms. The juxtaposition of the virtual world of the Internet with real-life scenarios presents novel challenges in the realm of privacy violations. The Internet era, coupled with the widespread use and integration of big data, has diminished the absolute right to privacy on the Internet. This paper examines the challenge of safeguarding the identity information of infectious patients through the lens of two theoretical frameworks -Kantianism and Utilitarianism- in an effort to address this ethical dilemma.


Aunque Internet ha aportado comodidad y rapidez a la vida humana, también ha dado lugar a frecuentes violaciones de la intimidad. En el contexto de las investigaciones epidemiológicas y la divulgación de información relativa a pacientes confirmados de covid-19, muchas personas han utilizado Internet como medio para difundir información y participar en cibercacerías, lo que ha dado lugar a violaciones en la intimidad de los implicados. Este fenómeno prevalece en el ámbito de Internet, donde los límites de la invasión de la intimidad se vuelven vagos. En las redes sociales, se manifiestan diversos tipos de violaciones de la intimidad, tanto por negligencia activa como pasiva. La yuxtaposición entre el mundo virtual de Internet con escenarios de la vida real plantea nuevos retos en el ámbito de las violaciones de la intimidad. La era de Internet, junto con el uso generalizado y la integración del bigdata, han mermado el derecho absoluto a la privacidad. Este artículo examina el reto de salvaguardar la información sobre la identidad de los pacientes infecciosos a través de la lente de dos marcos teóricos -el kantianismo y el utilitarismo- en un esfuerzo por abordar este dilema ético.

No contexto de investigações epidemiológicas e divulgação de informações em relação a pacientes confirmados de Covid-19, muitos indivíduos utilizaram a Internet como um meio para disseminar informação e participar de uma caçada cibernética, resultando em violações da privacidade para aqueles envolvidos. Esse fenômeno é particularmente prevalente no âmbito da Internet, onde os limites de invasão da privacidade se tornaram borrados. Vários tipos de infrações da privacidade, tanto negligências ativa como passiva, são evidentes em plataformas de redes sociais. A justaposição do mundo virtual da Internet com cenários da vida real apresenta novos desafios no âmbito das violações da privacidade. A era da Internet, juntamente com o amplo uso e integração de megadados (big data), diminuiu o direito absoluto à privacidade na Internet. Esse artigo examina o desafio de proteger a informação de identidade de pacientes infectantes através das lentes de dois enquadres teóricos -Kantianismo e Utilitarismo- em um esforço para abordar esse dilema ético.

RESUMEN

SUMMARY: The objective of this study was to observe the clinical efficacy of apatinib (AP) combined with 131I in the treatment of radioiodine-refractory differentiated thyroid cancer (RAIR-DTC) and the prognostic significance of MIP-1α after treatment, and to provide reference and guidance for future treatment and disease assessment of RAIR-DTC. One hundred and six patients with RAIR- DTC admitted to our hospital from January 2019 to October 2020 were selected for the study. All the patients were treated with TC surgery with 131I at our hospital, and 58 of them were subsequently transferred to AP treatment, which was considered as the research group; the other 48 patients were transferred to thyroid stimulating hormone (TSH) suppression treatment, which was considered as the control group. The clinical efficacy of the research group was better than that of the control group (P 0.05). After treatment, Tg, TL, maximum diameter of C/B lymph nodes, number of lymph nodes and number of calcified spots were lower in the research group than in the control group (P < 0.05). ROC analysis revealed that the predictive sensitivity of MIP-1α for prognosis of 3-year RAIR-DTC death in the research group of patients was 84.63 % and the specificity was 72.16 %. AP combined with 131I is effective in the treatment of RAIR-DTC and is worth using in the clinical practice. In addition, elevated levels of MIP-1α predicted a poor prognosis for patients with RAIR-DTC.

RESUMEN

Abstract The osseous vascular endothelium encompasses a vast intricate framework that regulates bone remodeling. Osteoporosis, an age-associated systemic bone disease, is characterized by the degeneration of the vascular architecture. Nevertheless, the precise mechanisms underpinning the metamorphosis of endothelial cells (ECs) with advancing age remain predominantly enigmatic. In this study, we conducted a systematic analysis of differentially expressed genes (DEGs) and the associated pathways in juvenile and mature femoral ECs, utilizing data sourced from the Gene Expression Omnibus (GEO) repositories (GSE148804) and employing bioinformatics tools. Through this approach, we successfully discerned six pivotal genes, namely Adamts1, Adamts2, Adamts4, Adamts14, Col5a1, and Col5a2. Subsequently, we constructed a miRNA-mRNA network based on miRNAs displaying differential expression between CD31hiEMCNhi and CD31lowEMCNlow ECs, utilizing online repositories for prediction. The expression of miR-466i-3p and miR-466i-5p in bone marrow ECs exhibited an inverse correlation with age. Our in vivo experiments additionally unveiled miR-466i-5p as a pivotal regulator in osseous ECs and a promising therapeutic target for age-related osteoporosis.

RESUMEN

Coenzyme Q10 (CoQ10) is a potent antioxidant that is implicated in the inhibition of osteoclastogenesis, but the underlying mechanism has not been determined. We explored the underlying molecular mechanisms involved in this process. RAW264.7 cells received receptor activator of NF-κB ligand (RANKL) and CoQ10, after which the differentiation and viability of osteoclasts were assessed. After the cells were treated with CoQ10 and/or H2O2 and RANKL, the levels of reactive oxygen species (ROS) and proteins involved in the PI3K/AKT/mTOR and MAPK pathways and autophagy were tested. Moreover, after the cells were pretreated with or without inhibitors of the two pathways or with the mitophagy agonist, the levels of autophagy-related proteins and osteoclast markers were measured. CoQ10 significantly decreased the number of TRAP-positive cells and the level of ROS but had no significant impact on cell viability. The relative phosphorylation levels of PI3K, AKT, mTOR, ERK, and p38 were significantly reduced, but the levels of FOXO3/LC3/Beclin1 were significantly augmented. Moreover, the levels of FOXO3/LC3/Beclin1 were significantly increased by the inhibitors and mitophagy agonist, while the levels of osteoclast markers showed the opposite results. Our data showed that CoQ10 prevented RANKL-induced osteoclastogenesis by promoting autophagy via inactivation of the PI3K/AKT/mTOR and MAPK pathways in RAW264.7 cells.

RESUMEN

Abstract The complex pathogenesis of castration-resistant prostate cancer (CRPC) makes it challenging to identify effective treatment methods. Matrix metalloproteinase (MMP)-12 can degrade elastin as well as various extracellular matrix (ECM) components, which is associated with cancer progression. However, the relationship between MMP-12 and CRPC progression is poorly understood. In this study, we observed the effect of MMP-12 on the progression of CRPC and further explored its potential mechanism of action. High levels of MMP-12 were observed in patients with CRPC. We therefore developed cell co-culture and mouse models to study the function of MMP-12. Silencing MMP-12 in CRPC cells disrupted lipid utilization and autophagy marker expression via the CD36/CPT1 and P62/LC3 pathways, respectively, leading to reduced CRPC cell migration and invasion. Moreover, animal experiments confirmed that MMP-12-knockdown CRPC xenograft tumors exhibited reduced tumor growth, and the mechanisms involved the promotion of cancer cell autophagy and the inhibition of lipid catabolism. According to our results, MMP-12 played important roles in the progression of CRPC by disrupting adipocyte maturation and regulating cancer migration and invasion via the modulation of autophagy and lipid catabolism pathways.

RESUMEN

The present study utilized the spared nerve injury (SNI) to create a mouse model of depression to investigate the impact of esketamine on depressive-like behaviors, on the expression of PSD-95 and CRMP2 proteins, and on changes in neuronal dendritic spine plasticity in the prefrontal cortex (PFC). Depressive-like behavioral tests were performed 1 h after esketamine treatment, and the PFC tissues were obtained on the fourth day after completing the behavioral tests. Then, dendritic spine density and morphology in the PFC were measured using Golgi staining, and CRMP2 and PSD-95 proteins were obtained from PFC tissue by western blotting. The results of this study showed that esketamine significantly increased the immobility time in the forced swimming test and tail suspension test. In the open field test, esketamine increased the time spent in the open arms, the time spent in the central area, and the total distance covered. It also increased the protein expression levels of CRMP2 and PSD-95 in addition to the total and mature dendritic spine density of the PFC in SNI-depressed mice. Esketamine can significantly improve depression-like behaviors in SNI-depressed mice and promote an increase in dendritic spine density and maturation in the PFC. These effects may be associated with changes in CRMP2 and PSD-95 expression.

RESUMEN

Previous studies show that glycogen synthase kinase 3β (GSK3B) plays an important role in tumorigenesis. However, its role in cervical cancer is unclear. The present study silenced GSK3B with siRNAs and/or chemical inhibitors to determine its role in HeLa cervical cancer cell proliferation and migration as well as in xenograft tumor growth. Cell Counting Kit (CCK)-8 and 5-ethynyl-2'-deoxyuridine (EdU) assays were used to determine cell survival and proliferation. Scratch and Transwell® assays were used to evaluate cell migration. Xenograft tumors were used to evaluate the effect of GSK3B on tumor growth. Transcriptomic sequencing was used to clarify the mechanisms underlying the foregoing processes. Public databases and clinical specimens showed that GSK3B was upregulated in cervical cancer tissues and correlated with poor prognosis. In vitro experiments indicated that GSK3B inhibition reduced cell viability, proliferation, and migration. In vivo experiments demonstrated that GSK3B inhibition slowed xenograft tumor growth. Transcriptomic sequencing revealed that GSK3B inhibition modulated the phosphatidylinositol 3-carboxykinase (PI3K)/protein kinase B (Akt) and extracellular matrix (ECM)-receptor interaction signaling pathways. GSK3B inhibition decreased the protein levels of phosphorylated PI3K and Akt and the levels of mesenchymal markers but increased those of epithelial markers. An activator of the PI3K/Akt signaling pathway counteracted the suppressive effects of GSK3B inhibition on HeLa cell viability and proliferation and on PI3K/Akt signaling. Our data suggested that GSK3B regulated cervical cancer cell proliferation and migration by modulating the PI3K/Akt signaling pathway and epithelial-to-mesenchymal transition (EMT).

RESUMEN

Small nucleolar RNAs (snoRNAs) have robust potential functions and therapeutic value in breast cancer. Herein, we investigated the role SNORA5A in breast cancer. Samples from The Cancer Genome Atlas (TCGA) were reviewed. The transcription matrix and clinical information were analyzed using R software and validated in clinical tissue samples. SNORA5A was significantly down-regulated in breast cancer, and high expression of SNORA5A correlated with a favorable prognosis. High expression of SNORA5A induced a high concentration of tumor-associated macrophages M1 and a low concentration of tumor-associated macrophages M2. Moreover, SNORA5A were clustered in terms related to cancer and immune functions. Possible downstream molecules of SNORA5A were identified, among which TRAF3IP3 was positively correlated with M1 and negatively correlated with M2. The function of TRAF3IP3 in tumor inhibition and its relationship with macrophages in clinical tissue samples were in accordance with bioinformatics analysis results. SNORA5A could regulate macrophage phenotypes through TRAF3IP3 and serves as a potential prognostic marker for breast cancer patients.

RESUMEN

Abstract The cure rates for osteosarcoma have remained unchanged in the past three decades, especially for patients with pulmonary metastasis. Thus, a new and effective treatment for metastatic osteosarcoma is urgently needed. Anlotinib has been reported to have antitumor effects on advanced osteosarcoma. However, both the effect of anlotinib on autophagy in osteosarcoma and the mechanism of anlotinib-mediated autophagy in pulmonary metastasis are unclear. The effect of anlotinib treatment on the metastasis of osteosarcoma was investigated by transwell assays, wound healing assays, and animal experiments. Related proteins were detected by western blotting after anlotinib treatment, ATG5 silencing, or ATG5 overexpression. Immunofluorescence staining and transmission electron microscopy were used to detect alterations in autophagy and the cytoskeleton. Anlotinib inhibited the migration and invasion of osteosarcoma cells but promoted autophagy and increased ATG5 expression. Furthermore, the decreases in invasion and migration induced by anlotinib treatment were enhanced by ATG5 silencing. In addition, Y-27632 inhibited cytoskeletal rearrangement, which was rescued by ATG5 overexpression. ATG5 overexpression enhanced epithelial-mesenchymal transition (EMT). Mechanistically, anlotinib-induced autophagy promoted migration and invasion by activating EMT and cytoskeletal rearrangement through ATG5 both in vitro and in vivo. Our results demonstrated that anlotinib can induce protective autophagy in osteosarcoma cells and that inhibition of anlotinib-induced autophagy enhanced the inhibitory effects of anlotinib on osteosarcoma metastasis. Thus, the therapeutic effect of anlotinib treatment can be improved by combination treatment with autophagy inhibitors, which provides a new direction for the treatment of metastatic osteosarcoma.

RESUMEN

ABSTRACT Purpose: This study aims to evaluate the safety and efficacy of ultrasound-guided balloon dilation compared to non-balloon dilation for percutaneous nephrolithotomy (PCNL). Materials and methods: A systematic review and meta-analysis were conducted by searching PubMed, EMBASE, and the Cochrane Library. Results were filtered using predefined inclusion and exclusion criteria as described and meta-analysis was performed using Review Manager 5.4 software. Results: A total of six studies involving 1189 patients who underwent PCNL were included. The meta-analysis results demonstrated that compared to non-balloon dilation, balloon dilation was associated with reduced haemoglobin drop [mean difference (MD) = -0.26, 95% CI = -0.40 ~ -0.12, P = 0.0002], decreased transfusion rate [odds ratio (OR) = 0.47, 95% CI = 0.24 ~ 0.92, P = 0.03], shorter tract establishment time (MD = -1.30, 95% CI = -1.87 ~ -0.72, P < 0.0001) and shorter operation time (MD = -5.23, 95% CI = -10.19 ~ -0.27, P = 0.04). Conclusions: Overall, ultrasound-guided balloon dilatation offered several advantages in PCNL procedures. It facilitated faster access establishment, as evidenced by shorter access creation time. Additionally, it reduced the risk of kidney injury by minimizing postoperative haemoglobin drop and decreasing the need for transfusions. Moreover, it enhanced the efficiency of surgery by reducing the operation time. However, it is important to note that the quality of some included studies was subpar, as they did not adequately control for confounding factors that may affect the outcomes. Therefore, further research is necessary to validate and strengthen these findings.

RESUMEN

Objective To explore the impact of severe weather on road traffic injuries (RTIs). Methods Relevant literature on the impact of meteorology on the occurrence and resulting casualties of road traffic injuries was searched. Meta-analysis was performed on the included literature using state16.0 software. Results A total of 28 articles were included. The results of meta-analysis showed that heat wave, cloudy day, snowy day, rainy day and other severe weather such as storm had a statistically significant impact on the occurrence of road traffic injuries. Severe weather such as storms had a statistically significant impact on RTIs casualties. Conclusion Heat wave, cloudy day, snowy day, rainy day, storm and other bad weather are independent risk factors for the occurrence of RTIs. Storm is a risk factor for accident casualties. There is not enough evidence to show that low temperature, cold wave and heavy fog are the influencing factors of road traffic accidents.

RESUMEN

Objective To explore the correlation between the incidence of foodborne diseases and meteorological factors in Jinan, and to provide targeted measures for the prevention and control of foodborne diseases. Methods Data from the reporting systems of two sentinel hospitals for active surveillance of foodborne diseases from 2013 to 2021 in Jinan were collected. The meteorological data in the same period in Jinan were also collected. The generalized additive model was used to explore the nonlinear relationship between meteorological factors and the incidence of foodborne diseases, and threshold function analysis was use to perform subsection regression. Results The incidence of foodborne diseases was positively correlated with daily average temperature (rs=0.23), relative humidity (rs=0.05), and daily average wind speed (rs=0.01), and negatively correlated with daily average air pressure (rs=-0.19). Based on the GAM results and segmented regression analysis of meteorological factors, it was found that when the daily average temperature was below or above the threshold of 24.63°C, for every 1°C increase in daily average temperature, the incidence of foodborne diseases correspondingly increased by 0.04% and 0.18%. When the daily average wind speed was above the threshold of 2.26 m/s, the incidence of foodborne diseases decreased by 0.36% for every 1 m/s increase in the daily average wind speed. Conclusion Nine years of observation and data analysis have shown that meteorological factors such as daily average temperature, relative humidity, air pressure, and wind speed are related to the incidence of foodborne diseases. These findings suggest that meteorological factors may be important factors leading to foodborne diseases, which provides an important scientific basis for formulating effective prevention and control measures.

RESUMEN

OBJECTIVE To provide reference for safe drug use in patients with anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC). METHODS Clinical pharmacists participated in the diagnosis and treatment of a patient with ALK-positive NSCLC who developed bilateral pleural effusion and hemolytic anemia after taking alectinib; regarding symptoms such as pleural effusion and hemolytic anemia in the patient, clinical pharmacists investigated the patient’s history of medication and disease, as well as potential drug interaction; to consider the correlation between the patient’s use of alectinib and the duration of pleural effusion and hemolytic anemia, clinical pharmacists suggested that clinical doctors discontinued alectinib and used reduced dose treatment after the pleural effusion improved, but the patient suffered from bilateral pleural effusion and hemolytic anemia again; after evaluating the correlation between alectinib and bilateral pleural effusion and hemolytic anemia using the Naranjo’s assessment scale, clinical pharmacists recommend permanent discontinuation of alectinib and jointly recommend replacement with ensartinib with clinical physicians. RESULTS Physicians adopted the suggestions of clinical pharmacists. The pleural effusion subsequently regressed and hemolytic anemia improved after replacing the drug. The correlation between alectinib and bilateral pleural effusion and hemolytic anemia was confirmed. CONCLUSIONS Clinical pharmacists participate in pharmaceutical monitoring of ALK-positive NSCLC patients, assist clinical doctors in developing personalized medication recommendations, and ensure the safety of patient medication.

RESUMEN

ObjectiveTo investigate the effect and mechanism of Dendrobium mixture (DMix)-containing serum on high glucose-induced podocyte injury in mice. MethodThe MPC5 mouse glomerular podocytes were cultured in vitro, and the optimal glucose concentration for modeling, modeling time, and concentration of DMix-containing serum for administration were determined. The cells were classified into normal (5.5 mmol·L-1 glucose+10% blank serum), model (30 mmol·L-1 glucose+10% blank serum), DMix-containing serum (30 mmol·L-1 glucose+10% DMix-containing serum), ferroptosis inhibitor (Fer-1, 30 mmol·L-1 glucose+10% blank serum+1 μmol·L-1 Fer-1) groups. The corresponding kits were used to measure the levels of Fe2+ and lactate dehydrogenase (LDH) in cells. Enzyme-linked immunosorbent assay was employed to determine the content of glutathione (GSH) and lipid peroxide (LPO) in cells. Fluorescence probe was used to measure the reactive oxygen species (ROS) level. Real-time fluorescence quantitative polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels, respectively, of Wilms' tumor-1 (WT-1), desmin, long chain acyl-CoA synthase 4 (ACSL4), and glutathione peroxidase 4 (GPX4) in podocytes. ResultCompared with the blank group, the intervention with 30 mmol·L-1 glucose for 48 h reduced podocyte viability (P<0.01), and the 10% DMix-containing serum showed the most significant improvement in podocyte viability (P<0.01). Compared with the normal group, the model group presented elevated levels of Fe2+, LDH, LPO, and ROS, lowered GSH level, up-regulated mRNA and protein levels of desmin and ACSL4, and down-regulated mRNA and protein levels of WT-1 and GPX4 (P<0.01). Compared with the model group, the DMix-containing serum lowered the Fe2+, LDH, LPO, and ROS levels, elevated the GSH level, down-regulated the mRNA and protein levels of desmin and ACSL4, and up-regulated the mRNA and protein levels of WT-1 and GPX4 in podocytes (P<0.05, P<0.01). ConclusionDMix-containing serum exerts a protective effect on high glucose-induced podocyte injury by inhibiting ferroptosis.

RESUMEN

In 2020, an international expert panel proposed to replace nonalcoholic fatty liver disease with metabolic associated fatty liver disease (MAFLD). Recent studies have shown that there is a higher risk of chronic kidney disease (CKD) in the MAFLD population and that MAFLD is an independent risk factor for CKD. However, up to now, there are still no guidelines on the prevention and treatment of MAFLD-related CKD. Based on the Delphi method, the authors led a multidisciplinary team of 50 authoritative experts from 26 countries to reach a consensus on some open-ended research issues about the association between MAFLD and CKD, which can help to clarify the important clinical association between MAFLD and the risk of CKD and improve the understanding of the epidemiology, pathogenesis, management, and treatment of MAFLD and CKD, so as to establish a framework for the early prevention and management of these two common and interrelated diseases.

RESUMEN

ObjectiveTo investigate the effect of transplantation of bone marrow mesenchymal stem cells (BMSCs) co-cultured with bone marrow-derived M2 macrophages (M2-BMDMs), named as BMSCM2, on a rat model of liver cirrhosis induced by carbon tetrachloride (CCl4)/2-acetaminofluorene (2-AAF). MethodsRat BMDMs were isolated and polarized into M2 phenotype, and rat BMSCs were isolated and co-cultured with M2-BMDMs at the third generation to obtain BMSCM2. The rats were given subcutaneous injection of CCl4 for 6 weeks to establish a model of liver cirrhosis, and then they were randomly divided into model group (M group), BMSC group, and BMSCM2 group, with 6 rats in each group. A normal group (N group) with 6 rats was also established. Since week 7, the model rats were given 2-AAF by gavage in addition to the subcutaneous injection of CCl4. Samples were collected at the end of week 10 to observe liver function, liver histopathology, and hydroxyproline (Hyp) content in liver tissue, as well as changes in the markers for hepatic stellate cells, hepatic progenitor cells, cholangiocytes, and hepatocytes. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the N group, the M group had significant increases in the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in ALT and AST (P<0.01), and the BMSCM2 group had significantly better activities than the BMSC group (P<0.05). Compared with the N group, the M group had significant increases in Hyp content and the mRNA and protein expression levels of alpha-smooth muscle actin (α-SMA) in the liver (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in Hyp content and the expression of α-SMA (P<0.05), and the BMSCM2 group had a significantly lower level of α-SMA than the BMSC group (P<0.01). Compared with the N group, the M group had significant increases in the mRNA expression levels of the hepatic progenitor cell markers EpCam and Sox9 and the cholangiocyte markers CK7 and CK19 (P<0.01) and significant reductions in the expression levels of the hepatocyte markers HNF-4α and Alb (P<0.01); compared with the M group, the BMSC and BMSCM2 groups had significant reductions in the mRNA expression levels of EpCam, Sox9, CK7, and CK19 (P<0.05) and significant increases in the mRNA expression levels of HNF-4α and Alb (P<0.05), and compared with the BMSC group, the BMSCM2 group had significant reductions in the mRNA expression levels of EpCam and CK19 (P<0.05) and significant increase in the expression level of HNF-4α (P<0.05). ConclusionM2-BMDMs can enhance the therapeutic effect of BMSCs on CCl4/2-AAF-induced liver cirrhosis in rats, which provides new ideas for further improving the therapeutic effect of BMSCs on liver cirrhosis.
