Objective To explore the long-term and short-term therapeutic effects and mechanisms of electroacupuncture at Baihui(GV20)point and Dazhui(GV14)point in rats with ischemic stroke.Methods Thirty rats were randomly divided into a sham-operated group,a model group,and an electroacupuncture group,with 10 rats in each group.The model group and the electroacupuncture group were subjected to middle cerebral artery occlusion(MCAO)using the modified Longa method.The electroacupuncture group received electroacupuncture at Baihui point and Dazhui point once daily for one week.Long-term neurological recovery was assessed using the adhesive removal test and the forelimb placement test at 14,21 and 28 days after MCAO.On the second day after MCAO,cerebral cortical histopathological changes were observed using transmission electron microscopy,the expression of Iba-1 in cortical tissue was detected by immunofluorescence,and the expression levels of hypoxia-inducible factor 1α(HIF-1α),vascular endothelial growth factor(VEGF),interleukin 1β(IL-1β),and tumor necrosis factor α(TNF-α)in cortical tissue were measured by Western Blot.Results(1)Compared with the sham-operated group at the same time points,the model group showed prolonged adhesive removal time and increased forelimb stepping times at 14,21 and 28 days after MCAO(P＜0.05).Compared with the model group at the same time points,the electroacupuncture group exhibited significantly shortened adhesive removal time and reduced forelimb stepping times at 14,21 and 28 days after MCAO(P＜0.05).Within 28 days after MCAO,the adhesive removal time was gradually decreased,and forelimb stepping times were gradually reduced.(2)On the second day after MCAO:compared with the sham-operated group,the model group showed degeneration and necrosis of microglia in cortical ischemic penumbra,mitochondrial damage,increased expression of Iba-1 in cortical tissue,and elevated levels of HIF-1α,VEGF,IL-1β and TNF-α,with statistically significant differences(P＜0.05).Compared with the model group,the electroacupuncture group exhibited the improvement of microglia injury in cortical ischemic penumbra,reduced expression of Iba-1 in cortical tissue and decreased levels of HIF-1α,VEGF,IL-1β and TNF-α,with statistically significant differences(P＜0.05).Conclusion Electroacupuncture at Baihui point and Dazhui point can improve symptoms in rats with ischemic stroke in the long term and ameliorate degeneration and necrosis of cortical microglia in the ischemic penumbra in the short term.The mechanism may be related to the downregulation of HIF-1α,VEGF,IL-1β and TNF-α expressions in cerebral cortical tissue and the inhibition of microglial transformation to the M1 phenotype.

Objective To investigate the microbiome composition of deep invasive endometriosis lesions,offering novel insights into its pathogenesis,diagnosis,and treatment strategies.Methods From May 2021 to May 2022,we collected samples of normal endometrium(normal group,n=10),endometrium from patients with deep infiltrating endometriosis(DIE endometrium group,n=14),and lesions from these patients(DIE lesion group,n=10)for 16s rRNA sequencing analysis.We employed the bacterial community diversity algorithm(alpha diversity and beta diversity),principal coordinate analysis(PCoA)distance matrix algorithms(Bray-Curtis and Unifrac matrices),as well as the biological identification algorithm(LeFSe)to investigate microbiome differences between groups and identify differentially abundant bacteria and enriched KEGG functions.Results The diversity of the three groups did not show any significant difference,while the β diversity exhibited a statistically significant distinc-tion(P=0.005 5).The focus group had a relatively low abundance of Firmicutes at the phylum level and a relatively increased abundance of Fusobacteria.At the genus level,there was an increased relative abundance of Enterococcus and Prevotella.LEFse analysis suggested that Proteobacteria and Gammaproteobacteria were the main dominant in the lesion group.Notably,Gamma proteobacteria emerged as a key differential species among the three groups'microbial flora with statistical significance(P=0.021 2).Conclusion Compared to the normal group and DIE group,there was a significant increase in the abundance of Fusobacteria,Proteobacteria,Gammaproteobacteria,Enterococcus,and Prevotella.These findings offer novel therapeutic targets for the prevention and intervention of deep infiltrating endometriosis.

Objective:To investigate the impact of exogenous lactate on the replication of dengue virus type 2 (DENV-2) in Raw264.7 cells, mouse bone marrow-derived macrophages (BMDMs) and THP-1 cells and explore its association with cell activation.Methods:BMDMs from BALB/c mouse bone marrow were prepared and evaluated by flow cytometry to detect the proportion of F4/80 + CD11b + cells. Glucose transporter type 1 (GLUT1), hexokinase 2 (HK2), and monocarboxylate transporters 4 (MCT4) expression at mRNA level in BMDMs at different time points after DENV-2 infection were measured by qRT-PCR. The content of lactate in the culture supernatants was quantified via colorimetric assay. CCK-8 assay was used to evaluate the impacts of different concentrations of lactate on the viability of Raw264.7 cells, BMDMs, and THP-1 cells. qRT-PCR was used to detect the expression of DENV-2 E gene, TGF-β, CD86, retinoic acid-inducible gene Ⅰ (RIG-Ⅰ), IFN-β, interferon-stimulated gene 15 (ISG15), and ISG56 at mRNA level in cells infected with DENV-2 at different MOIs in the presence of different concentrations of lactate. Meanwhile, flow cytometry was used to analyze the expression of CD86 and CD206. Results:The percentage of BMDMs was (87.53±1.66)%. GLUT1 expression at mRNA level exhibited a decrease in BMDMs at 24 h after DENV-2 (MOI=3) infection following a transient increase at 12 h ( P<0.05), while HK2 expression at mRNA level was higher that than in blank control and inactivated DENV-2 infection groups at 12, 24, and 36 h ( P<0.01). Besides, there was an increase in both MCT4 mRNA level and the content of lactate in culture supernatants at 24 h after DENV-2 (MOI=1.5) infection ( P<0.05). The viability of the three types of cells remained above 80% when the concentration of lactate was 31.25 mmol/L. Lactate at the concentration of 35 mmol/L increased the expression of the DENV E gene at mRNA level in DENV-2-infected BMDMs at MOI=1 or MOI=2 ( P<0.05). Besides, it promoted the expression of DENV E gene at mRNA level in Raw264.7 and THP-1 cells ( P<0.001) as well as the expression of CD163, TGF-β, RIG-Ⅰ, IFN-β, ISG15 and ISG56 at mRNA level in BMDMs at MOI=1.5, but inhibited the expression of CD86 at mRNA level in BMDMs ( P<0.05). It also up-regulated CD206 protein expression ( P<0.01) and down-regulated CD86 protein expression ( P>0.05) in BMDMs. Conclusions:Exogenous lactate enhances DENV-2 replication in both human- and murine-derived macrophages and that might correlate with M2 macrophage polarization.

Objective To assess the safety and therapeutic impact of propofol target-controlled infusion combined with alfentanil for vocal polyp excision.Methods From January 2023 to January 2024,vocal polyp ectomy removal surgery patients 80 cases in Ganzhou People's Hospital's were selected and randomly assigned into group A(40 cases)and group F(40 cases).In the anesthetic induction sequence,the two subject groups in the clinical trial had their propofol plasma target concentration set at 3.5μg/ml.Rocuronium bromide was administered at a dosage of 0.6mg/kg,followed by a slow and careful injection.In group F,this was succeeded by an injection of fentanyl at 3μg/kg.In contrast,group A received an intravenous injection of alfentanil at a dosage of 20μg/kg.In both groups,tracheal intubation was executed when muscle relaxation had been achieved.Monitoring and documentation of hemodynamic fluctuations during the perioperative stages.Records were kept for the procedure's conclusion time,the time frame for regaining consciousness and extubation,and any adverse effects experienced.Results While the contrast of mean arterial pressure(MAP)and heart rate(HR)between two groups at each time point from To to T4 were statistically non-significant(P＞0.05).Compared with preoperative baseline(To),MAP and HR were lower in both groups at all time points within group at T1,T2,T3 and T4(P＜0.05),the within-group examination of these parameters across time points and their interactions did show quantifiable differences(P＜0.05).The interval from regaining consciousness to extubation was shorter in group A than that in group F(P＜0.05).Additionally,the quantity of propofol and the number of unanticipated effects were diminished in group A than those in group F(P＜0.05).Conclusion In the context of vocal polypectemy,the administration of propofol via a targeted infusion combined with alfentanil maintains hemodynamic stability,minimizes propofol dosing in contrast to fentanyl,and is linked to faster awakening times and a lower occurrence of adverse effects.

Objective:To assess the impact of health insurance packaged payment in medical communities on the economicburden of patients,income and satisfaction of medical staff in counties.Methods:Using sample data from 2018-2022 from the national monitoring counties of medical communities,taking 2020 as the year of implementation of packaged payment,a double difference model was constructed with county population density and county per capita GDP as the control variables to assess the impact of packaged payment on the economic burden of patients,medical staff income and satisfaction in the county.Results:The packaged payment policy reduced the economic burden of patients to a certain extent and had a statistically significant positive effect on medical staff income in 2021,but it did not significantly increase the satisfaction of both supply and demand.Conclusion:The implementation of health insurance packaged payment of the MEC will not increase the economic burden of patients.It has a good pro-poor effect,and the income of medical staff has been improved to some extent,but there is still room for optimisation and improvement of the policy.
