Objective To observe the clinical efficacy of acupuncture combined with western medicine in the treatment of rheumatoid arthritis(RA)complicated with mild anemia under the guidance of"Dongyuan acupuncture".Methods A total of 80 cases of patients definitively diagnosed as RA complicated with mild anemia of deficiency of qi and blood were selected and randomly divided into the observation group and the control group according to the random number table method,those who were admitted to the wards and outpatient clinics of the Department.of Rheumatology,Chongqing Hospital of The First Affiliated Hospital of Guangzhou University of Chinese Medicine from February 2024 to September 2024,with 40 cases in each group.The control group was given conventional treatment with western medicines,while the observation group was additionally treated with acupuncture under the guidance of"Dongguan acupuncture".The course of treatment covered four consecutive weeks.After one month of treatment,the clinical efficacy of the two groups was evaluated,and the changes in traditional Chinese medicine(TCM)syndrome scores and Visual Analogue Scale(VAS)of pain scores,as well as Disease Activity Scores(DAS-28)before and after treatment were observed in the two groups.The changes of rheumatoid factor(RF),C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),red blood cell count(RBC),and hemoglobin(Hb)levels before and after treatment were compared between the two groups.The safety and incidence of adverse reactions in the two groups were also evaluated.Results(1)After treatment,the TCM syndrome scores of the patients in the observation group were improved significantly(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(2)After treatment,the VAS scores and DAS-28 scores of the patients in the two groups were improved significantly(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(3)After treatment,the RF,CRP,and ESR levels of patients in the two groups were improved significantly(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05);after treatment,there was a significant improvement in the RBC level of the observation group(P＜0.05),but the difference was not statistically significant when compared with the control group(P＞0.05);after treatment,the Hb level of patients in the two groups were improved significantly(P＜0.05),and the improvement in the observation group was significantly superior to that in the control group,the difference being statistically significant(P＜0.05).(4)The total effective rate was 95.00％(38/40)in the observation group and 87.50％(35/40)in the control group,and the efficacy of the observation group was superior to that of the control group,the difference being statistically significant(P＜0.05).(5)The incidence of adverse reactions was 7.50％(3/40)in the observation group and 27.50％(11/40)in the control group,the incidence of adverse reactions in the observation group was significantly lower than that in the control group,the difference being statistically significant(P＜0.05).Conclusion Under the guidance of"Dongyuan acupuncture",the application of acupuncture combined with western medicine in the treatment of RA complicated with mild anemia can not only realize the complementarity of acupuncture and medicine,improve the clinical efficacy,reduce the level of inflammatory factors,and significantly alleviate the joint symptoms of the patients,but also increase the level of blood cells,improve the anemia condition of the patients and have fewer adverse reactions,thus enhancing their quality of life.

Objective To evaluate the clinical efficacy of Shengqing Jiangzhuo(lifting lucid yang and lowering turbid yin)Acupuncture Method,based on the"turbidity-clearness interaction"theory,combined with western medicine in treating gouty nephropathy(GN)patients with damp-heat accumulation syndrome.Methods A total of 117 patients diagnosed with GN from September 2023 to September 2024 at the First Affiliated Hospital of Guangzhou University of Chinese Medicine Chongqing Hospital were enrolled and randomly divided into three groups,with 39 cases in each group.The western medicine group received Febuxostat Tablets,the control group was given western medicine+conventional acupuncture,and observation group was given western medicine+Shengqing Jiangzhuo Acupuncture Method.All groups received 4 weeks of treatment.Clinical efficacy,traditional Chinese medicine(TCM)syndrome scores,visual analogue scale(VAS)of pain scores,and laboratory parameters—including serum uric acid(UA),blood urea nitrogen(BUN),creatinine(Scr),estimated glomerular filtration rate(eGFR),β2-microglobulin(β2-MG),24-hour urinary protein(24h-UTP),cystatin C(CysC)were assessed.The erythrocyte sedimentation rate(ESR),and C-reactive protein(CRP)were compared before and after treatment.Results(1)The total effective rate was 71.79%(28/39)in the western medicine group,84.62%(33/39)in the control group,and 92.31%(36/39)in the observation group.The observation group demonstrated statistically significant superiority over the western medicine group(P＜0.05),while showing marginally better efficacy than the control group without statistical significance(P＞0.05).(2)After treatment,all three groups exhibited significant improvements in ESR,CRP,and UA levels(P＜0.05).The observation group significantly outperformed the other two groups in reducing ESR and CRP levels(P＜0.05),and was statistically superior to the western medicine group in lowering UA levels(P＜0.05),though no significant difference was observed versus the control group for UA improvement(P＞0.05).The control group showed significantly greater reductions in ESR,CRP,and UA levels than the western medicine group(P＜0.05).(3)After treatment,Scr,BUN,and eGFR levels were significantly improved in all groups(P＜0.05).The observation group achieved significantly better improvements in Scr and eGFR than the other two groups(P＜0.05).However,no statistical difference existed between the control and western medicine groups for Scr or eGFR enhancement(P＞0.05).No intergroup differences were detected in BUN improvement(P＞0.05).(4)Significant differences emerged in β2-MG and CysC levels among all groups after treatment(P＜0.05).Both observation and control groups demonstrated statistically significant improvements in 24-hour 24h-UTP(P＜0.05),whereas the western medicine group showed no significant change(P＞0.05).The observation group significantly outperformed the other groups in reducing 24h-UTP and β2-MG levels(P＜0.05),and was superior to the western medicine group in lowering CysC(P＜0.05),though no difference versus the control group was observed for CysC reduction(P＞0.05).The control group showed no statistical advantage over the western medicine group in improving 24h-UTP,β 2-MG,or CysC(P＞0.05).(5)After treatment,TCM syndrome scores and VAS scores were significantly improved in all groups(P＜0.05).The observation group achieved significantly greater reductions in TCM syndrome scores and VAS scores than the western medicine group(P＜0.05).The control group showed statistically superior VAS score improvement versus the western medicine group(P＜0.05),but no significant differences emerged in TCM syndrome score improvement compared to either group(P＞0.05).No statistical difference existed between observation and control groups for VAS score reduction(P＞0.05).Conclusion Shengqing Jiangzhuo Acupuncture Method,grounded in the"turbidity-clearness interaction"theory,effectively reduces serum UA,controls inflammation,and preserves renal function in damp-heat accumulation type of GN,demonstrating significant therapeutic benefits.

Metal ion-promoted chemodynamic therapy(CDT) combined with photodynamic therapy(PDT) offers broad application prospects for enhancing anti-tumor effects. In this study, glycyrrhizic acid(GA), copper ions(Cu~(2+)), and norcantharidin(NCTD) were co-assembled to successfully prepare a natural small-molecule, carrier-free hydrogel(NCTD Gel) with excellent material properties. Under 808 nm laser irradiation, NCTD Gel responded to the tumor microenvironment(TME) and acted as an efficient Fenton reagent and photosensitizer, catalyzing the conversion of endogenous hydrogen peroxide(H_2O_2) within the tumor into oxygen(O_2), and hydroxyl radicals(·OH, type Ⅰ reactive oxygen species) and singlet oxygen(~1O_2, type Ⅱ reactive oxygen species), while depleting glutathione(GSH) to stabilize reactive oxygen species and alleviate tumor hypoxia. In vitro and in vivo experiments demonstrated that NCTD Gel exhibited significant CDT/PDT synergistic therapeutic effects. Further safety evaluation and metabolic testing confirmed its good biocompatibility and safety. This novel hydrogel is not only simple to prepare, safe, and cost-effective but also holds great potential for clinical transformation, providing insights and references for the research and development of metal ion-mediated hydrogel-based anti-tumor therapies.

This study explores the therapeutic differences and mechanisms of salt-processed Phellodendri Chinensis Cortex in improving insulin resistance(IR) based on network pharmacology, molecular docking, and cellular experiments. The components and intersection targets of Phellodendri Chinensis Cortex in improving IR were collected from databases, and a "drug-component-target-disease" network and protein-protein interaction(PPI) network were constructed to screen core components and targets. A total of 29 active components and 240 intersection targets were identified, of which 13 were core targets. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses were used to identify key signaling pathways, and molecular docking was performed to validate the binding activity between core components and targets. An IR model in HepG2 cells was induced using insulin combined with high glucose, and the effects of Phellodendri Chinensis Cortex before and after salt-processing on cell glucose consumption were evaluated. The expression of proteins related to the mitogen-activated protein kinase(MAPK) and phosphatidylinositol 3-kinase(PI3K)-protein kinase B(AKT) signaling pathways was detected by Western blot. The cellular experimental results showed that, compared with the model group, glucose consumption in the drug-treated groups was significantly increased(P<0.01), the phosphorylation level of extracellular regulated protein kinase(ERK) was decreased(P<0.05), the phosphorylation levels of PI3K and AKT were increased, and the expression of glucose transporter 4(GLUT4) was also upregulated(P<0.05). Furthermore, the effect of salt-processed Phellodendri Chinensis Cortex was better than that of raw Phellodendri Chinensis Cortex. The study demonstrates that Phellodendri Chinensis Cortex, both before and after salt-processing, improves IR by regulating the expression of related proteins in the MAPK and PI3K-AKT signaling pathways, with enhanced effects after salt-processing.

BACKGROUND: Atrial fibrillation (AF) is a common cardiac arrhythmia in the elderly. This study aimed to evaluate urban-rural disparities in its prevalence and management in elderly Chinese. METHODS: Consecutive participants aged ≥ 65 years attending outpatient clinics were enrolled for AF screening using handheld single-lead electrocardiogram (ECG) from April 2017 to December 2022. Each ECG rhythm strip was reviewed from the research team. AF or uninterpretable single-lead ECGs were referred for 12-lead ECG. Primary study outcome comparison was between rural and urban areas for the prevalence of AF. The Student's t-test was used to compare mean values of clinical characteristics between rural and urban participants, while the Pearson's chi-square test was used to compare between-group proportions. Multivariate stepwise logistic regression analysis was performed to estimate the association between AF and various patient characteristics. RESULTS: The 29,166 study participants included 13,253 men (45.4%) and had a mean age of 72.2 years. The 7073 rural participants differed significantly (P ≤ 0.02) from the 22,093 urban participants in several major characteristics, such as older age, greater body mass index, and so on. The overall prevalence of AF was 4.6% (n = 1347). AF was more prevalent in 7073 rural participants than 22,093 urban participants (5.6% vs. 4.3%, P < 0.01), before and after adjustment for age, body mass index, blood pressure, pulse rate, cigarette smoking, alcohol consumption and prior medical history. Multivariate logistic regression analysis identified overweight/obesity (OR = 1.35, 95% CI: 1.17-1.54) in urban areas and cigarette smoking (OR = 1.62, 95% CI: 1.20-2.17) and alcohol consumption (OR = 1.42, 95% CI: 1.04-1.93) in rural areas as specific risk factors for prevalent AF. In patients with known AF in urban areas (n = 781) and rural areas (n = 338), 60.6% and 45.9%, respectively, received AF treatment (P < 0.01), and only 22.4% and 17.2%, respectively, received anticoagulation therapy (P = 0.05). CONCLUSIONS In China, there are urban-rural disparities in AF in the elderly, with a higher prevalence and worse management in rural areas than urban areas. Our study findings provide insight for health policymakers to consider urban-rural disparity in the prevention and treatment of AF.

Objective:To investigate the impact of early cleavage on the pregnancy and obstetric outcomes of fresh cycle single cleavage embryo and single blastocyst transfer.Methods:A retrospective study was conducted to analyze 794 patients who underwent single cleavage embryo transfer and 1466 patients who underwent single blastocyst transfer in the reproductive medicine center of our hospital from August 2018 to December 2022 during the fresh cycle treatment of in vitro fertilization/intracytoplasmic sperm injection and embryo transfer(IVF/ICSI-ET).The patients were divided into two groups according to whether the transferred embryos underwent normal early cleavage.In the single cleavage embryo transfer,there were 383 cases in the normal early cleavage group(early cleavage group)and 411 cases in the non normal early cleavage group(non-early cleavage group);in the single blastocyst transfer,there were 815 cases in the early cleavage group and 651 cases in the non-early cleavage group.The pregnancy and obstetric outcomes of the early cleavage group and non-early cleavage group were compared in single cleavage embryo transfer and single blastocyst transfer.Results:In the single cleavage embryo transfer,the human chorionic gonadotropin(hCG)positive rate,clinical pregnancy rate,and live birth rate in the early cleavage group were significantly higher than those in the non-early cleavage group(64.0％vs.55.7％,P=0.018;54.6％vs.47.0％,P=0.032;46.7％vs.38.7％,P=0.022).There were no significant differ-ences in biochemical abortion rate,multiple pregnancy rate,abortion rate,early abortion rate,premature delivery rate,low birth weight rate,macrosomia rate,and birth defect rate compared with the non-early cleavage group(P＞0.05);in the single blastocyst transfer,there were no significant differences in pregnancy outcomes and obstetric indicators between the early cleavage group and the non-early cleavage group(P＞0.05).Multivariate Logistic regression analysis showed that after adjusting for confounding factors on pregnancy outcomes,in the single cleavage embryo transfer,the hCG positive rate(aOR 1.54,95％CI 1.12-2.11,P=0.008),clinical preg-nancy rate(aOR 1.49,95％CI 1.09-2.04,P=0.012),and live birth rate(aOR 1.53,95％CI 1.12-2.09,P=0.008)in the early cleavage group were significantly higher than those in the non-early cleavage group;in the sin-gle blastocyst transfer,there were no significant differences for these indicators between the early cleavage group and the non-early cleavage group(P＞0.05).Conclusions:Transplantation of single cleavage embryo with nor-mal early cleavage can significantly improve the clinical pregnancy rate and live birth rate.Early cleavage during single blastocyst transplantation had no significant effect on clinical pregnancy outcome.Early cleavage had no significant effect on the obstetric outcomes of single cleavage embryo and single blastocyst transfer.

Objective To explore the value of cuprotosis-related genes in the diagnosis and disease progression of chronic obstructive pulmonary disease(COPD).Methods Differential gene expression related to COPD was identified through gene expression omnibus series(GSE)10006,GSE11784,GSE19407,and GSE8545 datasets,and compared with previously identified cuprotosis-related genes to identify differentially expressed genes.Weighted gene co-expression network analysis(WGCNA)was then performed on GSE8545 and GSE19407 datasets to explore the correlation between cuprotosis-related genes and COPD phenotypes.GSE20257 dataset was introduced to validate the gene's expression level changes and further investigate the impact of smoking on gene expression levels.Subsequently,the effects of smoking cessation on gene expression levels were explored by using the GSE7895 datasets.GSE162635 dataset was then utilized to investigate the impact of differentially expressed cuprotosis-related genes on the severity of COPD.Results The study identified cyclin-dependent kinase inhibitor 2A(CDKN2A)as a potential cuprotosis-related gene associated with COPD,confirming that smoking upregulated CDKN2A expression in lung tissue,which returns to baseline levels after smoking cessation.Finally,the study confirmed that the expression level of CDKN2A was associated with the prognosis of COPD,increasing with severity.Conclusion The study identifies CDKN2A as a cuprotosis-related gene associated with COPD,and shows promising diagnostic potential and correlation with disease severity.

Objective:To determine whether spinal cord injury (SCI) triggers secondary neuroinflammation and neuronal injury in remote brain regions by impairing the drainage function of the meningeal lymphatic vessels (MLVs).Methods:Fifty-two female C57BL/6 mice were assigned with the random number table into four groups ( n=13 per group): sham group, SCI group, adeno-associated virus negative control group (negative control group), and adeno-associated virus overexpressing VEGF-C group (VEGF-C group). The sham group underwent laminectomy without spinal cord injury. In the SCI group, negative control group and VEGF-C group, T 9 contusion was made to establish the SCI models using a modified Allen′s impactor. At 4 weeks before SCI modeling, the negative control group and VEGF-C group were injected via the cisterna magna with 3 μl adeno-associated virus for negative control or adeno-associated virus for VEGF-C overexpression. At 56 days after injury, Alexa Fluor? 647 ovalbumin conjugate (OVA-647) was injected via the cisterna magna as a tracer. Two hours later, the proportion of OVA-647 in the deep cervical lymph nodes (dCLN) was detected. Immunofluorescence was performed to assess the proportion of MLVs marker lymphatic vessel endothelial hyaluronan receptor-1 (LYVE-1) and expression levels of microglial marker ionized calcium-binding adaptor molecule 1 (Iba1) in the cerebral cortex, hippocampus, midbrain, and thalamus across the experimental groups. ELISA was employed to quantify the levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) and Nissl staining was used to assess neuronal counts in these regions. Results:At 56 days after injury, the OVA-647 proportion in the dCLN was higher in the sham group than that in the SCI group and negative control group ( P<0.01), whereas the SCI group and negative control group showed a lower OVA-647 proportion in the dCLN than the VEGF-C group ( P<0.05). At 56 days after injury, the dural LYVE-1 proportion was higher in the sham group than that in the SCI group and negative control group ( P<0.01), whereas it was lower in the SCI group and negative control group than that in the VEGF-C group ( P<0.05). At 56 days after injury, the count of Iba1-positive microglia across all the above-mentioned regions was increased in the SCI group and negative control group ( P<0.01), compared with that in the sham group, whereas it was reduced in these regions in the VEGF-C group, compared with that in the SCI group and negative control group ( P<0.01). At 56 days after injury, TNF-α and IL-1β levels in these regions were both elevated in the SCI group and negative control group when compared with those in the sham group ( P<0.05), whereas they were reduced in the VEGF-C group, compared with those in the SCI group and negative control group ( P<0.05). At 56 days after injury, neuronal survival in the regions was decreased in the SCI group and negative control group, compared with that in the sham group ( P<0.05), whereas it was increased in the VEGF-C group, compared with that in the SCI group and negative control group ( P<0.05). Conclusion:SCI can induce secondary neuroinflammation and neuronal damage in remote brain regions by impairing the drainage function of MLVs.
