Retinopathy caused by myopia is the first cause of irreversible blinding eye disease in China.The TCM methods to prevent and control myopia mainly include Chinese materia medica and TCM appropriate techniques,which have the advantages of good efficacy,simple operation,and few adverse reactions.This paper believed that internal and external pathogenic factors act on the brain and eyes,breaking their homeostasis,leading to rhythmic disorders,and imbalance of essence,qi and blood is the main pathogenesis of myopia.Based on the idea of"nature and human in the same rhythm"and"the same treatment for common diseases",targeting the above pathogenesis,the method of"brain-eye synchronization"was proposed to restore the homeostasis of the brain and eyes to prevent and control myopia in children and adolescents,and the treatment rules were to regulate the rhythms of the time,harmonize the qi and blood,nourish the blood to soften the tendons,and replenish the essence and blood,so as to achieve the effect of brain-eye synchronization and the treatment of the spirit and the body together.This article summarized the theoretical basis of"brain-eye synchronization"and its clinical application in traditional Chinese and Western medicine,with a view to providing new ideas for the prevention and control of myopia in children and adolescents.

Traditional Chinese medicine upholds the unity of nature and humanity as its fundamental principle,asserting that man is in harmony with heaven and earth and corresponds to the sun and moon.Human life processes align with the circadian rhythms of nature,exhibiting periodic temporal changes-concepts that Western medicine defines as biological rhythms.The"opening-closing-pivot"of the three yin and three yang meridians represents the primary mode of interaction between nature and humanity.This mechanism regulates the transformation of yin and yang to qi within the body,ensuring synchronization with the circadian rhythm.Building upon this foundation,the concept of"the harmony of rhythms and states"was proposed to explain human growth and aging."Rhythms"encompass not only circadian cycles but also the movement of qi and blood,as well as the contraction rhythm of muscle fascia,among other physiological processes."States"refer to the dynamic evolution and transformation of qi during the"opening-closing-pivot"stages in both time and space."Harmony"pertains not only to the individual physiological balance of"rhythms"or"states"but also to their coherent interaction.The fundamental cause of myopia is"the disharmony of rhythms and states",considering that rhythm disorders,qi and blood disorders,and fascia imbalances contribute to this disease.Based on this understanding,myopia prevention and treatment should center on"regulating rhythms and states",with adjusting the pivot to brighten the eyes as the core therapeutic principle throughout the entire cycle of myopia.Treatment should be tailored to different disease stages and supplemented with methods such as time-based regulation,qi and blood harmonization,tendon relaxation and collateral dredging,and essence and blood nourishment to prevent and manage myopia effectively.

To identify clinical viral diseases characterized by reproductive disorders and abortion,a quadruple qPCR method was established for simultaneous detection of PRV,PPV,PCV2 and AS-FV.Four pairs of specific primers and probes were designed according to the conserved genes of four viruses in the NCBI gene bank.The annealing temperature,primer concentration and probe concentration of the reaction were optimized,and the specificity,sensitivity and repeatability of the method were tested.The results showed that the method could not detect other pathogens except the target ones.The minimum detection limit of PRV,PPV,PCV2 and ASFV was 10 copies.Intra-group and inter-group repeatability tests showed that the coefficient of variation of C,values be-tween different batches was less than 3％,indicating that the method was highly specific,sensitive and stable.Establishment of an efficient and sensitive quadruple qPCR method provides technical reference for the clinical prevention and control of porcine pseudorabies virus disease,porcine circo-virus disease,porcine parvovirus disease and African swine fever.

This study investigates the effects of pseudorabies virus(PRV)infection on the antiviral immune signaling pathways and type Ⅰ interferon factors in mouse trigeminal ganglion(TG)cells.In this experiment,primary TG cells were infected with PRV at a multiplicity of infection(MOI)of 1,while mice were infected via a drop-nose method using 106,29 TCID50 of PRV.Real-time fluorescence quantitative PCR(qPCR),Western blot and ELISA were used to assess gene tran-scription,protein expression,and the secretion of IFN-α and IFN-β.The results indicated that PRV infection of mouse TG primary cells led to alterations in the gene and protein expression of RIG-Ⅰ,MAVS,and IRF3,as well as the phosphorylation of IRF3 and IKBα both in vivo and ex vivo.ELISA results showed that PRV infection could regulate the secretion of IFN-α and IFN-β in mouse primary TG cells and mouse TGs.The results of RIG-Ⅰ signaling pathway-related proteins and the secretion of IFN-a and IFN-β were analyzed using Western blot after using siRNA to interfere with RIG-Ⅰ expression in TG cells.The results showed that siRIG-Ⅰ successfully inter-fered with RIG-Ⅰ protein expression in TG cells and caused changes in the expression of down-stream proteins such as MAVS and IRF3,and also regulated the secretion of IFN-α and IFN-β in TG cells.Furthermore,the results indicated that PRV infection induced the expression of RIG-Ⅰ in mouse TG progenitor cells,regulating the antiviral immune response of type Ⅰ interferon factors in TG cells through the RIG-Ⅰ-MAVS-IRF3 signaling axis.Notably,PRV inhibited the expression of IRF3 in TG cells while significantly upregulating the expression of IFN-β during the later stages of infection,which may be an important factor in the important reason for the rapid mortality ob-served in mice during the late stages of PRV infection.This experiment elucidates part of the anti-viral immune mechanism mediated by the RIG-Ⅰ-MAVS-IRF3 signaling pathway in regulating type Ⅰ interferon factor after PRV infection of mouse TG cells,as well as the discovery of differ-ent trends of IRF3 protein changes in vivo and ex vivo,laying the groundwork for future in-depth studies.

Objective:To investigate the molecular mechanism by which 2',4'-dihydroxychalcone(D2)inhibits proliferation,migration,and epithelial-mesenchymal transition(EMT)in colorectal cancer cells through miR-7-5p-mediated autophagy.Methods:Human colorectal cancer cell lines HCT-15 and SW620 were treated with D2 at concentrations of 0,12.5,25,and 50 μmol/L.Cell proliferation and clonogenic capacity were evaluated using MTT and colony formation assays.Cell migration was assessed by wound healing and Transwell assays.WB assay was used to detect the expression of EMT-related proteins,autophagy-related proteins,and key components of the PI3K/AKT/mTOR pathway.Autophagosome formation was visualized by immunofluorescence staining.TCGA database and KEGG pathway analyses were performed to evaluate miR-7-5p expression and its association with colorectal cancer.RT-qPCR was used to quantify miR-7-5p expression,and lentiviral transduction was employed to establish stable miR-7-5p knockdown or overexpression cell lines.Results:D2 significantly inhibited colorectal cancer cell proliferation,migration,and EMT(P<0.05 or P<0.01).TCGA and KEGG analyses revealed that miR-7-5p expression was downregulated in colorectal cancer and closely associated with disease progression.D2 treatment(12.5,25,and 50 μmol/L)significantly upregulated miR-7-5p expression in HCT-15 and SW620 cells(P<0.01).At 25 μmol/L,D2 increased the expression of autophagy-related proteins(LC3 and p-ULK1)and inhibited the PI3K/AKT/mTOR signaling pathway(P<0.05),accompanied by increased autophagosome formation(P<0.01).In miR-7-5p-knockdown cells treated with D2,the levels of LC3 and p-ULK1 were significantly reduced compared to D2-only treated cells(P<0.05 or P<0.01).Conclusion:D2 upregulates miR-7-5p to induce autophagy,thereby inhibiting colorectal cancer cell proliferation,migration,and EMT,possibly through suppression of the PI3K/AKT/mTOR signaling pathway.

Objective:To investigate the impacts of the radiosensitivity of cell lines on a microdosimetric kinetic model (MKM) used in carbon-ion radiotherapy.Methods:The saturation-corrected specific energy ( ) of monoenergetic carbon ions was calculated using the Kiefer-Chatterjee (K-C) track structure model. Correction curve f(LET) was derived from experimental data on relative biological effectiveness (RBE) (RBE DSB-LET) defined based on the double-strand DNA break of the Chinese hamster ovary (CHO) and Fibroblast cell lines irradiated using carbon ions with varying linear energy transfer (LET) values. Then, based on the MKM, the D10-LET curves, as well as α and β databases, of the CHO and Fibroblast cell lines with varying radiosensitivity were determined. Results:Compared to the clinically applied MKM, the predicted D10 after correction while accounting for cell line radiosensitivity agreed better with experimental D10 values of the CHO and Fibroblast cell lines. Specifically, compared to experimental values in the literature, the D10 values calculated in the study and determined using the MKM showed mean squared errors (MSEs) of 0.04 and 0.71, for the CHO cell line and 0.35 and 0.55, respectively, for the Fibroblast cell line. For monoenergetic carbon ions with varying LET values, the calculated α and β values generally increased with cellular radiosensitivity. Conclusions:Incorporating cellular radiosensitivity into the MKM framework serves as a more specific method for RBE assessment while also providing a reference for advancing MKM applications and achieving the fine-scale calculations of RBE in carbon-ion radiotherapy.

Distal transradial access(dTRA)was first applied in coronary heart disease intervention by Kiemeneij in 2017,dTRA has become an important technological advancement of coronary interventional therapy.This approach,performed by puncturing the distal radial artery within the anatomical snuffbox or Hegu point,significantly reduces the incidence of radial artery occlusion compared with conventional transradial access and shortens compression time to 2-3 hours after procedure.Clinical evidence confirms the efficacy of dTRA in facilitating complex percutaneous coronary interventions,including stenting of left main coronary artery bifurcation lesions and recanalization of chronic total occlusions.Its application has progressively expanded to neurointerventional procedures(cerebral angiography),tumor embolization(transarterial chemoembolization for hepatocellular carcinoma),and peripheral vascular interventions.Despite increasing clinical adoption,dTRA still faces challenges,including a long learning curve and relatively lower initial puncture success rates.Combined with the current paucity of robust evidence-based data,the viability of dTRA as a routine interventional access route remains a subject of debate.This article systematically reviews the anatomical landmarks,clinical advantages,limitations,and multidisciplinary applications of dTRA.This article aims to provide practical guidance for interventionalists and promote the standardization of this technique in daily clinical practice.

To establish a TaqMan-based multiplex RT-qPCR method for the identification of Japa-nese encephalitis virus(JEV),Porcine reproductive and respiratory syndrome virus(PRRSV),and Classical swine fever virus(CSFV),this study designed and synthesized three pairs of specific primers and probes based on the conserved sequences of JEV E,PRRSV ORF6,and CSFV E2 a-vailable in the NCBI GenBank.By optimizing the reaction system and protocol,a multiplex RT-qPCR method for detecting these three viruses was developed and applied to the detection of clini-cal samples.The results showed that the established TaqMan multiplex RT-qPCR specifically am-plified the gene fragments of JEV,PRRSV,and CSFV,and did not amplify other non-target genes,indicating good specificity of the method.Intra-assay and inter-assay repeatability tests showed that the coefficient of variation(Cv)values were all below 3％,demonstrating that the method has ex-cellent repeatability.Sensitivity tests revealed that the minimum detectable amount for the recom-binant plasmids of the three viruses was 100 copies/pL.Using the established method,a total of 969 samples,including blood,aborted fetuses,semen,and deceased pigs,from 26 pig farms in Guizhou Province were tested.The detection rates were 34.3％(332/969)for JEV,28.3％(274/969)for PRRSV,and 19.8％(192/969)for CSFV.The co-infection rates were 10.1％(98/969)for JEV and PRRSV,12.1％(117/969)for JEV and CSFV,and 14.6％(141/969)for CSFV and PRRSV.Additionally,the triple co-infection rate of JEV,PRRSV,and CSFV was 7.9％(77/969).These results indicate that the TaqMan multiplex RT-qPCR method developed in this study is ef-fective for detecting these three viruses in pig farms,providing technical support for identifying vi-ral causes of reproductive disorders.

This paper explores the therapeutic approach for glaucoma based on the concept of "jueyin （厥阴） as the closing phase" from the perspectives of time and space. In traditional Chinese medicine， jueyin governs inward， converging aspect of qi， representing the crucial turning point between the end of yin and the emergence of yang， as well as the transformation between yin and yang. When the closing and descending function of jueyin operates smoothly， it promotes the inward convergence and smooth descent of qi， enabling the internal retention of blood， spirit， and emotions， which nourishes the internal organs and moistens the meridian-sinews. Conversely， dysfunction of this "closing" mechanism results in a disturbance of yin and yang， a mixture of cold and heat， and disharmony of qi and blood. It is proposed that "failure of jueyin to properly close and descend" is a core pathomechanism of glaucoma. From the perspective of spatiotemporal theory， clinical treatment should focus on "regulating the closing function of jueyin and harmonizing yin and yang". The modified Wumei Pill （乌梅丸） is recommended to adjust the ascending-descending and entering-exiting dynamics of jueyin qi transformation， thereby restoring its free flow， achieving yin and yang balance， and ensuring nourishment to the ocular system.
