Central nervous system(CNS)degenerative disorders refer to a spectrum of pathological alterations triggered by struc-tural damage to cerebral neural tissues,clinically manifested as diverse neurological dysfunction syndromes,including multiple sclerosis(MS),neurodegenerative diseases(NDs),and ische-mic stroke.The hallmark pathological features of these disorders involve irreversible neuronal damage and decompensation of functional neural networks,ultimately leading to progressive neurological deficits.Notably,with the accelerating global popu-lation aging,the incidence of these diseases has surged signifi-cantly.According to WHO statistics,they now rank among the top three global causes of disability and mortality.Current re-search has confirmed that the pathogenesis of CNS degenerative disorders exhibits high heterogeneity,encompassing multifaceted pathophysiological processes such as genetic predisposition,oxi-dative stress,protein misfolding,and metabolic dysregulation.This intricate pathogenic network not only complicates clinical differential diagnosis but also poses substantial challenges to the development of precision therapeutic strategies.Importantly,re-cent studies have revealed that mitochondrial homeostasis disrup-tion-induced inflammatory cascades(termed mitochondrial in-flammation)play a pivotal regulatory role in neurodegenerative progression.Key molecular mechanisms include impaired mito-phagy,aberrant mitochondrial DNA(mtDNA)release and NL-RP3 inflammasome activation.This review systematically deci-phers the molecular regulatory network of mitochondrial inflam-mation,with a focus on its biological effects in critical pathologi-cal events such as blood-brain barrier disruption,microglial hy-peractivation and neuronal apoptosis.The overarching aim is to provide a theoretical foundation for developing innovative thera-peutic strategies targeting mitochondrial homeostasis restoration.

BACKGROUND:Mongolian medicine Echinops sphaerocephalus L.is a commonly used medicine for bone injury in Mongolian medicine.It is effective for tendon injury,fracture,bone nonunion,bone fever,tingling,sore and other diseases.Our previous studies have confirmed that Mongolian medicine Echinops sphaerocephalus L.can promote the proliferation and osteogenic differentiation of bone marrow mesenchymal stem cells,but its effect on angiogenesis in the process of bone defect repair is unknown.OBJECTIVE:To investigate the effect of Echinops sphaerocephalus L.on in vitro angiogenesis in human umbilical vein vascular endothelial cells and to explore the angiogenesis-promoting active ingredients and their mechanisms of action of Echinops sphaerocephalus L.using network pharmacology technology.METHODS:The ethanol extract of Echinops sphaerocephalus L.was prepared and preserved by freeze-drying.The proliferation,migration,chemotaxis and angiogenesis of human umbilical vein endothelial cells were observed after treatment with different concentrations(1 000,100,and 10 μg/mL)of Echinops sphaerocephalus L.The active components and possible signaling pathways that promoted angiogenesis were enriched and analyzed by network pharmacology.RESULTS AND CONCLUSION:(1)The effect of Echinops sphaerocephalus L.on angiogenesis was regulated by its mass concentration:at low mass concentration(10 μg/mL),Echinops sphaerocephalus L.could promote the proliferation,migration,chemotaxis and angiogenesis of human umbilical vein vascular endothelial cells;on the contrary,Echinops sphaerocephalus L.inhibited the proliferation,migration,and chemotaxis of human umbilical vein endothelial cells at high mass concentration(1 000 μg/mL).However,the inhibitory effect of Echinops sphaerocephalus L.on angiogenesis was not significant at high mass concentration due to the limitation of experimental time.10 μg/mL Echinops sphaerocephalus L.could up-regulate the mRNA expression of angiogenesis-associated factors,including kinase insert domain receptor,vascular endothelial growth factor A,and hypoxia-inducible factor α,and thereby influenced angiogenesis during bone repair.(2)Network pharmacological analyses indicated that Echinops sphaerocephalus L.may bind to eight core targets(TGFB1,TNF,IL-6,STAT3,CTNNB1,IL-1B,AKT1,and HIF-1A)through four core active components(apigenin,caffeic acid,quercetin,and chlorogenic acid)to exert an effect on angiogenesis,atherosclerosis,multiple viral infections,and tumor angiogenesis-related signaling pathways.

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.

Objective:To investigate the expression and clinical significance of gamma-aminobutyric acid receptor-associated protein-like 1 (GABARAPL1) in patients with gouty arthritis (GA).Methods:Differentially expressed genes (DEGs) between GA patients and healthy controls were identified by the Gene Expression Omnibus (GEO) database, followed by the screening of autophagy-related DEGs (au-DEGs) associated with GA. Peripheral blood single nucleated cells (PBMCs) were collected from 80 male GA patients and 60 healthy controls treated at the Affiliated Taizhou People′s Hospital of Nanjing Medical University between March to December 2023. Real-time quantitative PCR (qRT-PCR) was employed to assess the expression of au-DEGs, bisulfite sequencing PCR (BSP) was used to determine the methylation status of the GABARAPL1 promoter, and chromatin immunoprecipitation combined with qPCR (ChIP-qPCR) was used to analyze the binding activity of histone H3 to the GABARAPL1 promoter. Spearman ′s Correlations between GABARAPL1 expression and clinical indicators such as serum uric acid (UA) were analyzed. The diagnostic efficacy of GABARAPL1 in PBMCs for GA was evaluated using receiver operating characteristic (ROC) curves. Results:The relative expression of GABARAPL1 in PBMCs was significantly higher in GA patients compared to healthy controls (1.91±0.72 vs. 0.84±0.39, t=11.27, P<0.001). Spearman correlation analysis revealed that GABARAPL1 expression was positively correlated with UA, white blood cell count, neutrophil count, monocyte count, globulin, urea, and creatinine ( r=0.61, 0.40, 0.46, 0.32, 0.28, 0.22, 0.34; P<0.05 for all), and negatively correlated with lymphocyte count, albumin, high-density lipoprotein cholesterol, apolipoprotein A1, and estimated glomerular filtration rate ( r=-0.18, -0.34, -0.33, -0.50, -0.22; P<0.05 for all). ROC curve analysis showed that GABARAPL1 in PBMCs had high diagnostic efficacy for GA, with an area under the curve of 0.936. No significant differences in the methylation levels of GABARAPL1 promoter regions MC1 and MC2 were observed between GA patients and healthy controls ( t=2.28、1.43, P<0.05 for all), whereas histone H3 acetylation levels were significantly elevated in GA patients ( t=11.19, P<0.001). Conclusion:The expression of GABARAPL1 in PBMCs is significantly upregulated in GA patients, which may be associated with increased histone H3 acetylation at its promoter. The high expression of GABARAPL1 may contribute to the pathogenesis of GA by regulating autophagy and holds promise as a diagnostic biomarker and potential therapeutic target for GA.

This study explored the drying kinetics of Salviae Miltiorrhizae Radix et Rhizoma(SM), established the suitable models simulating the drying kinetics, and then analyzed the dynamic changes of active components during the drying processes with different methods, aiming to provide a basis for the establishment of suitable drying methods and the quality control of SM. The drying kinetics were studied based on the drying curve, drying rate, moisture effective diffusion coefficient, and drying activation energy, and the appropriate drying kinetics model of SM was established. The drying performance of different methods, such as hot air drying, infrared drying, and microwave drying of SM was evaluated, and the changes in the content of 10 salvianolic acids and 6 tanshinones during drying were analyzed by UPLC-TQ-MS. The Technique for Order Preference by Similarity to an Ideal Solution(TOPSIS) was employed to evaluate the quality of SM dried with different methods. The results showed that the drying rate and moisture effective diffusion coefficient of SM increased with the rise in drying temperature, and the maximum drying rates of different methods were in the order of microwave drying > infrared drying > hot air drying, slice > whole root. The drying rate decreased with the rise in temperature and the extension of drying time. The activation energy of hot air drying was higher than that of infrared drying in SM. The most suitable model for simulating the drying process of SM was the Page model. The TOPSIS results suggested infrared drying at 50 ℃ was the optimal drying method for SM. During the drying process, the content of salvianolic acids increased in different degrees with the loss of moisture, among which salvianolic acid B showed the largest increase of 44 times compared with that in the fresh medicinal material. Tanshinones also existed in the fresh herb of SM, and the content of tanshinone Ⅱ_A increased by 3 times after drying. The results provided a basis for the establishment of suitable drying methods and the quality control of SM.

OBJECTIVE: To investigate the correlation of seminal plasma oxidation reduction potential (ORP), normalized oxidation-reduction potential (nORP) and sperm DNA fragmentation index (DFI) to sperm motion parameters, and their clinical predictive value for oligoasthenozoospermia (OAZ). METHODS: This study included 433 male subjects visiting the Clinic of Andrology in our hospital from March to May 2024. According to sperm concentration and the percentage of progressively motile sperm (PMS), we divided them into a normal control (n = 119), an oligozoospermia (OZ, n = 118), an athenozoospermia (AZ, n = 119) and an OAZ group (n = 77). Using the electrode method, we measured the seminal plasma ORP, calculated nORP=ORP/sperm concentration (mV/［10⁶/ml］), and determined DFI and high DNA chromatin sperm (HDS) by flow cytometry based on sperm chromatin structure assay (SCSA), followed by comparison among the four groups in age, abstinence days, semen volume, total sperm count, sperm concentration, PMS, non-progressively motile sperm (NPMS), immotile sperm (IMS), curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity (LIN), straightness(STR), wobble (WOB), DFI, HDS, ORP and nORP. Using the receiver operating characteristic (ROC) curve, we assessed the predictive value of DFI, ORP and nORP for OAZ, and analyzed the correlation of DFI, ORP and nORP to sperm motion parameters by Pearson and Spearman analyses. RESULTS: Statistical analysis revealed statistically significant differences among the four groups in semen volume, abstinence days, total sperm count, sperm concentration, PMS, NPMS, IMS, total sperm motility, VCL, VSL, VAP, STR, DFI, HDS, ORP and nORP (P < 0.05), but not in age, LIN and WOB (P > 0.05). The area under the ROC curve (AUC) for the predictive value of DFI for OAZ was 0.880, with the critical value of 8.920, sensitivity of 74.8% and specificity of 88.2%; that of ORP for AZ was 0.698, with the critical value of 155.375, sensitivity of 70.6% and specificity of 64.7%; and that of nORP for OZ was 0.999, with the critical value of 9.844, sensitivity of 98.3% and specificity of 99.2%. Pearson and Spearman correlation analyses showed that DFI was correlated positively with age, abstinence days, semen volume, IMS, HDS and ORP, but negatively with PMS, NPMS, total sperm motility, VCL, VSL, VAP and STR; ORP positively with abstinence days, semen volume, IMS, DFI and nORP, but negatively with PMS, NPMS, total sperm motility, VSL, LIN and STR; and nORP positively with HDS, but negatively with abstinence days, total sperm count, sperm concentration, PMS and NPMS. CONCLUSION Oxidative stress (OS) may be an important pathological factor for elevated ORP, increased DFI and changes of routine sperm motion parameters, consequently leading to OAZ. As OS markers, DFI and ORP have a high predictive value for OS-induced OAZ.

OBJECTIVE: To investigate the effect of acupuncture on advanced cancer patients by meta-analysis. METHODS: Nine databases (the Cochrane Central Register of Controlled Trials, MEDLINE, Web of Science, Embase, China National Knowledge Infrastructure, the Cumulative Index to Nursing and Allied Health Literature, Chinese Biomedical Literature Database, China Science and Technology Journal Database, and WanFang Data) were searched for randomized controlled trials (RCTs) on acupuncture in advanced cancer patients published from inception to February 13, 2023 and updated to June 1, 2023. Primary outcomes were quality of life (QOL), while secondary outcomes were pain, fatigue, and adverse events (side effects). Data synthesis was performed using RevMan V.5.3 to calculate pooled effect sizes. RoB-2 was used for the risk of bias, and the quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. RESULTS: Totally 17 RCTs involving 1,178 participants were included, 15 of which were pooled for meta-analysis. Most studies demonstrated some concern for the overall risk of bias. The pooled data indicated that acupuncture was associated with improved QOL [mean difference (MD)=6.67, 95% confidence interval (CI): 5.09 to 8.26], pain (MD=-1.18, 95% CI -2.28 to -0.08), and adverse events (risk ratio=0.30, 95% CI: 0.26 to 0.57) compared with control groups. Fatigue outcome was not included. Heterogeneity was substantial, and GRADE evidence was very low for both QOL and pain. CONCLUSIONS Acupuncture could benefit patients with advanced cancer and is considered safe compared with usual care. However, the evidence regarding QOL and pain outcomes requires further validation. It is crucial to encourage the development of high-quality studies to strengthen this evidence. (Registry No. CRD42023423539).
