Objective:
To investigate the effect of targeted silencing of DNA methyltransferase 3A(DNMT3A) on collagen deposition, proliferation and migration activity of mouse lung fibroblasts(PFs).
Methods:
In order to ensure the proliferation and migration activity of primary fibroblasts, the lung tissues of neonatal C57 suckling mice were taken, PFs were extracted after being sheared, and the morphology was observed and identified under the microscope. PFs cells were activated by 5 ng/ml TGF-β1for 24 h after cell attachment, and DNMT3A silencing model was constructed by small interfering RNA; The experiment was divided into control group, TGF-β1group, TGF-β1+ siRNA-NC group and TGF-β1+ siRNA-DNMT3A group. The protein expressions of DNMT3A, α-smooth muscle actin(α-SMA) and Collagen Ⅰ were detected by Western blot; Real time quantitative reverse transcription polymerase chain reaction(RT-qPCR) was used to detect the mRNA expression changes ofDNMT3A,α-SMAandCollagenⅠ. The proliferation ability of PFs was detected by CCK-8 and EdU staining; the migration ability of PFs was detected by scratch test and Transwell migration test.
Results:
Compared with the control group, TGF-β1induced the increase of DNMT3A in the activated PFs cell group(P<0.01), the protein and mRNA levels of fibrosis and proliferation related indicators α-SMA and Collagen Ⅰ also increased(allP<0.05), and the proliferation and migration ability of PFs increased(allP<0.000 1). Compared with the siRNA-NC group, the protein expression levels of DNMT3A(P<0.000 1) and related indicators α-SMA(P<0.01) and Collagen Ⅰ(P<0.01) significantly decreased in the DNMT3A silencing group by Western blot, and the mRNA levels ofDNMT3A,α-SMAandCollagenⅠby RT-qPCR also decreased(allP<0.001), and the proliferation(P<0.01) and migration ability(P<0.05) of PFs cells decreased compared with the control group.
Conclusion
Silencing DNMT3A can inhibit the deposition of collagen and the proliferation of PFs. DNMT3A can promote the proliferation and migration of PFs, and then promote the activation of PFs and the development of pulmonary fibrosis. This process may be regulated by DNA methylation modification.

ObjectiveStudies have shown that nuciferine has anti-cerebral ischemia effect, but the specific mechanism of action has not been elaborated. Based on the transcriptome results, the pharmacological mechanism of nuciferine against cerebral ischemia was analyzed from multiple dimensions including tissue, cell, pathological process, biological process and signaling pathway. MethodsThirty SD rats were randomly divided into the sham group, model group and nuciferine group(40 mg·kg-1) according to weight. Except for the sham group, the model of middle cerebral artery occlusion(MCAO) was established by thread embolization method after 30 min of administration in the other two groups. Twenty-four hours after surgery, transcriptome sequencing was used to detect the gene expression profiles in the cortex penumbra of rat cerebral tissue, and gene ontology(GO) and kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were performed for differentially expressed genes. The mechanismof nuciferine against cerebral ischemia was analyzed from 5 dimensions of tissue, cell, pathological process, biological process and signaling pathway by the transcriptome-based multi-scale network pharmacology platform(TMNP). ResultsTranscriptome sequencing and gene quantitative analysis showed that 667 genes were significantly reversed by nuciferine. Further enrichment analysis of KEGG and GO suggested that the pathways of nuciferine involved regulating stress response, ion transport, cell proliferation and differentiation, and synaptic function. TMNP research found that at the tissue level, nuciferine could significantly improve the cerebral tissue injury caused by ischemia. At the cellular and pathological levels, nuciferine could play an anti-cerebral ischemia role by improving the state of various nerve cells, mobilizing immune cells, regulating inflammation. And at the level of biological processes and signaling pathways, nuciferine mainly acted on the processes such as vascular remodeling, inflammation-related signaling pathways, and synaptic signaling. ConclusionCombined with the results of transcriptome sequencing, gene quantitative analysis and TMNP, the mechanism of nuciferine against cerebral ischemia may be related to processes such as intervening in stress response and inflammation, affecting vascular remodeling and regulating synaptic function. These results can provide a basis and reference for further study of the pharmacological mechanism of nuciferine against cerebral ischemia.

Objective To analyze correlation of endolymphatic hydrops (EH) in the inner ear with age in Meniere’s disease (MD) patients. Methods A retrospective analysis were underwent in 101 definite unilateral MD patients. They were divided into young-age (<18 years old) group, middle-age (18-45 years old) group and elder-age (>45 years old) group. All patients underwent inner ear three-dimensional inversion-recovery with real reconstruction (3D-real IR) imaging 4 hours after intravenous gadolinium injection. EH rates among different groups were compared. Results The positive rates of EH in the young-age group, middle-age group and elder-age group were 68.2% (15/22), 54.5% (18/33) and 56.5% (26/46), respectively (P=0.567). There was no difference in the positive rates of EH in vestibule and cochlea among three groups. There was no difference in the rates of mild and significant EH in vestibule and cochlea among three groups. Conclusions Age might not be related to the occurrence of EH in the inner ear in MD patients.

ObjectiveThis study aims to observe the clinical effect of Danggui Liuhuang Tang (DGLHT) on patients with type 2 diabetes mellitus (T2DM) complicated by atherosclerotic cardiovascular disease (ASCVD) at high risk, focus on evaluating the influence of DGLHT on cardiovascular risk indicators such as flow-mediated dilation (FMD), atherogenic index of plasma (AIP), and triglyceride-glucose index (TyG), and explore the regulatory effect of DGLHT on the myeloid differentiation factor 88/nuclear factor-kappa B (MyD88/NF-κB) signaling pathway. MethodsThe clinical study was a single-center, double-blind, and randomized controlled trial. A total of 68 patients with T2DM-ASCVD at high risk for cardiovascular events with Yin deficiency and fire excess syndrome were enrolled and randomly assigned to a treatment group and a control group. The treatment group was given atorvastatin calcium tablets and DGLHT, while the control group was given atorvastatin calcium tablets and placebos. The treatment course was 12 weeks, with a final study completion of 30 patients in the treatment group and 29 in the control group. Changes in cardiovascular risk indicators such as FMD, AIP, TyG, and small dense low-density lipoprotein cholesterol (sdLDL-C) index were compared. Human umbilical vein endothelial cells (HUVECs) were used to establish a vascular endothelial injury and inflammation model. The protective effect of DGLHT on endothelial injury was verified by reverse transcription polymerase chain reaction (Real-time PCR) and Western blot . ResultsAfter 12 weeks of treatment, the AIP in the treatment group significantly decreased compared with that before the treatment (P<0.05). Compared with the control group, the treatment group showed significant improvements in FMD and TyG (P<0.05). Additionally, the treatment group demonstrated significant reductions in two-hour postprandial glucose (2 hPG), glycated albumin (GA), triglycerides (TG), apolipoprotein E (Apo E), and sdLDL-C (P<0.05). Analysis of traditional Chinese medicine (TCM) syndrome efficacy indicated that in the treatment group, Yin deficiency and fire excess syndromes, including dry throat and mouth (P<0.05), excessive thirst (P<0.01), tidal fever and night sweats (P<0.05), and dry stools (P<0.05), improved. Compared with the control group, the treatment group showed significant improvements in symptoms of dry throat and mouth (P<0.05) and excessive thirst (P<0.01). TCM syndrome scores significantly decreased (P<0.01), and the overall efficacy rate was 56.67%, significantly higher than the 10.34% observed in the control group (P<0.01). At the cellular level, increasing concentrations of DGLHT led to decreased messenger ribonucleic acid (mRNA) levels of pro-inflammatory cytokines interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interleukin-1-beta (IL-1β) in lipopolysaccharide (LPS)-stimulated HUVECs (P<0.01), with significant reductions in the high-concentration group (P<0.01). DGLHT may inhibit the expressions of MyD88 and phosphorylated (p)-NF-κB p65 proteins in a concentration-dependent manner. ConclusionDGLHT shows significant effects in reducing cardiovascular risks and may exert an anti-inflammatory effect by inhibiting the MyD88/NF-κB signaling pathway. This finding provides a new perspective for the prevention and treatment of cardiovascular diseases in high-risk individuals with T2DM-ASCVD.

ObjectiveTo explore quality difference factors of Perillae Caulis based on the contents of multiple chemical components and comprehensively evaluate the quality. MethodsA total of 32 batches of Perillae Caulis samples were collected from 12 producing areas such as Hebei, Anhui and Guangdong, and their diameter range, epidermis color and producing areas were recorded. Total flavonoids, total phenols, volatile oils, 5 active components and 84 volatile components in 32 batches of samples were quantitatively or semi-quantitatively determined by colorimetry, ultra performance liquid chromatography-photodiode array detector(UPLC-PDA) and gas chromatography-mass spectrometry(GC-MS). Then the differences between the contents of these components were analyzed by principal component analysis(PCA) and non-parametric test. According to the weights of the index components determined by PCA model, entropy weight-technique for order preference by similarity to ideal solution(TOPSIS) model was constructed to evaluate the quality of Perillae Caulis with different characters and origins. ResultsThere were significant differences in the composition of Perillae Caulis with different diameters, epidermis colors and producing areas, and 9 differential components were screened out, including 6 index constituents(total flavonoids, total phenols, caffeic acid, scutellarin, rosmarinic acid and luteolin) and 3 volatile components(caryophyllene oxide, (-)-humulene epoxide Ⅱ, 14-hydroxycaryophyllene), of which 6 index constituents were higher in samples with small diameter, purple-brown epidermis and southern origin, while the contents of 3 volatile components were higher in samples with large diameter, dark-brown epidermis and northern origin. A significant difference was shown in the model scores of different diameters, epidermis colors and origins(P<0.05), and the scores of Perillae Caulis with small diameter and purple-brown epidermis from southern area, especially Guangdong, had a high score. ConclusionThere are significant differences in the composition and content of chemical constituents between different diameters, epidermal colors and production areas of Perillae Caulis, samples showing small diameter, owing purple-brown epidermis, and originating from Guangdong were of higher-quality due to their higher content of 8 key indices.

ObjectiveTo investigate the dynamic expression profiles and potential regulatory mechanisms of long non-coding RNAs (lncRNAs) in male reproductive system aging. MethodsA naturally aging C57BL/6 mouse model was used and 4 mice were selected each at 3, 15, and 21 months of age. RNA was extracted from seven regions of the male reproductive tract (testis, efferent duct, initial segment of epididymis, caput epididymis, corpus epididymis, cauda epididymis, and vas deferens), followed by RNA sequencing and bioinformatics analysis. ResultsRegion-specific dynamic expression profiles of lncRNAs were constructed in the testis, epididymis (efferent duct, initial segment, caput, corpus, and cauda), and vas deferens of male mice. Combined with gene functional enrichment analysis, the functional associations of lncRNAs were elucidated in reproductive system aging. The differentially expressed lncRNAs in the aging testis were primarily involved in hormone biosynthesis and extracellular matrix organization, while those in the initial segment of the epididymis were closely related to cell recognition and epithelial cell migration. A comprehensive lncRNA expression atlas associated with male reproductive aging was established. ConclusionLncRNAs may participate in male reproductive aging through the regulation of the reproductive microenvironment, which provides key molecular targets and a research foundation for understanding age-related fertility decline.

Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2012 to 2024, and to provide a scientific basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze the incidence data of mumps in Guangxi from 2012 to 2024. Results A total of 159 873 mumps cases were reported from 2012 to 2024 in Guangxi, with an average annual reported incidence of 25.41/100 000, and no death. Mumps occurred every month, with the peak incidence mainly concentrated in April to July and October to January of the next year. There were 96,118 male cases (29.43 /100 000), and 63 755 female cases (21.07 /100 000). The male to female ratio was 1.40:1, and the difference between male and female was significant (χ2=4 321.276,P<0.05). The annual incidence of mumps showed a certain periodic change, with the incidence peak and trough alternating every 4 - 5 years. The majority of patients were under 15 years old, accounting for 85.32% of the total number of cases. The patients mainly included students, preschool children and scattered children. The highest average incidence was in Nanning City with 40 231 cases (42.08/100 000), and the lowest was in Qinzhou City with 3 466 cases (8.16/100 000). From 2012 to 2024, a total of 210 mumps outbreaks with 4 483 cases were reported in Guangxi. Conclusion The incidence of mumps in Guangxi from 2012 to 2024 shows a periodic change and obvious seasonality. People under 15 years old are the key group at risk of mumps. The prevention and control of the epidemic of mumps in schools and kindergartens should be strengthened. It is suggested to carry out long-term monitoring of mumps as well as immune effect research, and continue to maintain a high vaccination rate of 2 doses of mumps-containing vaccines.
