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.

Objective To investigate whether miR-15b-5p can alleviate airway inflammation in asthma by negatively regulating ubiquitin specific peptidase 9X (USP9X) to down-regulate the expression of phosphatidylinositol 4, 5-diphosphate 3-kinase catalytic subunit α/AKT serine/threonine kinase 1 (PIK3CA/AKT1) pathway. Methods USP9X was predicted to be a direct target of miR-15b-5p by using an online database (miRWalk), and the luciferase reporter gene assay was performed to verify it. Co-immunoprecipitation (CO-IP) was used to verify the direct binding between USP9X and PIK3CA and the role of USP9X and its small molecule inhibitor WP1130 in the deubiquitination of PIK3CA. C57 mice were randomly divided into Control group, OVA group, OVA combined with NC group and miR-15b-5p agomir group, with 10 mice in each group. BEAS-2B cells were induced with interleukin 13 (IL-13) and treated with miR-15b-5p mimic. HE, Masson, PAS, immunohistochemistry, immunofluorescence staining, flow cytometry, Western blot and quantitative real-time PCR(qRT-PCR) were performed. Results It was found that the administration of miR-15b-5p agomir and mimic could reduce peribronchial inflammatory cells and improve airway inflammation, and miR-15b-5p could target negative regulation of USP9X. USP9X could directly bind to PIK3CA and regulate PIK3CA level in a proteasome-dependent manner, and USP9X could deubiquitinate K29-linked PIK3CA protein. Down-regulation of USP9X could increase PIK3CA ubiquitination level. WP1130, a small molecule inhibitor of USP9X, has the same effect as knockdown of USP9X, both of which could increase the ubiquitination level of PIK3CA and reduce the protein level of PIK3CA. Conclusion The miR-15b-5p/USP9X/PIK3CA/AKT1 signaling pathway may provide potential therapeutic targets for asthma.

Porcine parvovirus(PPV)is a causative agent of porcine parvovirus infection(PPI),which significantly impacts the pig industry due to its association with reproductive dysfunction.The condition is characterized by stillbirth,mummified fetuses,fetal weakness,and abortion in pregnant sows.The pathogenic mechanism remains incompletely understood,with no effective therapeutic drugs available currently.Despite extensive research on the host's response to PPV in-fection and identification of various signaling pathway transduction mechanisms,a comprehensive understanding is still lacking.This review aims to summarize the current knowledge regarding al-terations in related signaling pathways following PPV infection,provide novel insights into the pathogenesis of PPV and facilitate the drug development.

This study aims to investigate the effects of Japanese encephalitis virus(JEV)on TLRs signaling pathway and its regulation of the secretion of inflammatory factors during the infection of testicular interstitial cells,In this study,the mRNA levels of TLR3,TLR7,TLR8,TRIF and MyD88 genes were detected by qPCR after 1 MOI dose of JEV was inoculated into testicular stro-mal cells at different time periods.Western blot assay was used to detect the expression levels of TLR3,TLR7,TRIF and MyD88 protein at 6 h after JEV infection,and ELISA was used to detect the expression levels of IL-1β,IL-6 and TNF-α at different time periods(6,12 and 24 h).The re-sults showed as follows:After 6 h of JEV infection,the mRNA levels of TLR3,TLR7,TRIF and MyD88 genes were significantly up-regulated(P＜0.05),and the mRNA levels of TLR8 genes were down-regulated(P＜0.05).Western blot results showed that the protein expressions of TLR3,TLR7,TRIF and MyD88 were significantly up-regulated when JEV infected testicular stromal cells for 6 h(P＜0.05),which was consistent with the corresponding mRNA transcription levels.There was no significant change in TLR8 protein expression.ELISA results showed that 6 h after JEV infection of testicular stromal cells,IL-6 was significantly increased(P＜0.01),and the expressions of IL-1β and TNF-α were not changed.TLR3,TLR7,TLR8,TRIF and MyD88 were si-lenced by siRNA,and the silenced cells were inoculated with JEV for 6 h,and IL-6 expression lev-els were detected by ELISA.The results showed that silenced TLR3,TLR7,TLR8,TRIF and MyD88 could significantly reduce the increase of IL-6 secretion induced by JEV infection(P＜0.05).These results indicated that JEV could induce the expression of inflammatory factor IL-6 by activating TLR3,TLR7 and TLR8 signaling pathway after infection of testicular stromal cells.This study provides a reference for further elucidating the mechanism of reproductive disorders caused by JEV infection.

Porcine circovirus type 2(PCV2)is the main pathogen causing porcine circovirus related diseases.PCV2 infection in pigs may lead to porcine dermatitis and nephrotic syndrome(PDNS)and weaned piglets multiple system failure syndrome(PMWS),etc.At present,the pathogenic mechanism is not fully understood.PCV2 is a single strand of negative link DNA,which can cause immune suppression in the body and lead to increased secondary susceptibility,which has a syner-gistic effect with various pig diseases and brings major economic losses to the pig industry.Al-though there are commercial vaccines,the prevention of vaccines has certain limitations and there is no effective drug treatment so far,an outbreak will threaten people's life and health and public safety,resulting in significant economic losses.In order to understand the latest progress of PCV2 escape mechanism and prevention and control,this paper summarizes the inhibition of interferon production,regulation of apoptosis,regulation of autophagy,regulation of pyroptosis and inflam-matory response,evasion of adaptive immune response,and prevention and control of PCV2,in or-der to provide new theoretical ideas for the research and prevention and control of PCV2.

The theory of “rhythmic equilibrium” is developed based on the idea of sharing the same laws between nature and human， and by integrating with the medical concept of homeostasis of calm yin and sound yang. "Rhythmic instability" runs through the entire process of the occurrence and development of myopia， covering four aspects including imbalance of rhythm （high-risk period of myopia）， imbalance of qi and blood （premyopia）， imbalance of sinew-membranes （low myopia）， and imbalance of essence and blood （high myopia）. The treatment should focus on adjusting the rhythm and harmonizing situation， which can help balance yin and yang， and nourish the eye system. For high-risk period of myopia， adjusting sleeping time and increasing outdoor activities are stressed to adjust the rhythm in a timely manner. In the stage of premyopia， appropriate techniques of traditional Chinese medicine （TCM） such as pressing needles can be added to harmonize qi and blood. In the period of low myopia， appropriate TCM techniques such as pressing needles and ear acupuncture are mainly used， supplemented by modified Danggui Buxue Decoction （当归补血汤） to soften tendons and unblock collaterals. During the period of high myopia， it is recommended to control the development of existing disease and put focus on nourishing essence and blood， usually with Zhujing Pill （驻景丸） or modified Siwu Wuzi Decoction （四物五子汤） to restore the stability of the eyes and the whole body.

Objective To evaluate the effect of hypothermic machine perfusion (HMP) on the expression levels of inflammatory cytokines in rat kidney. Methods Thirty male rats were randomly divided into the control (Control group), static cold storage group (SCS group) and HMP group, with 10 rats in each group. The velocity, intrarenal resistance and pH value of perfusion effluent were recorded during HMP. The expression levels of CXC chemokine ligand (CXCL)1, CXCL2, interferon (IFN)-β1, IFN-α4, CC chemokine ligand (CCL)2, CCL20, interleukin (IL)-17α, IL-17C and tumor necrosis factor (TNF)-α messenger RNA (mRNA) in renal tissues were evaluated by reverse transcription polymerase chain reaction (RT-PCR). Pathological changes of the kidney were observed by hematoxylin-eosin (HE) staining. Results During HMP, the velocity and intrarenal resistance remained stable, and the pH value of perfusion effluent was decreased slowly. RT-PCR showed that the relative expression levels of CXCL1, CXCL2, CCL2, CCL20, IL-17α, IL-17C and TNF-α mRNA in the SCS and HMP groups were higher compared with those in the Control group. Compared with the SCS group, the relative expression levels of CXCL1, CXCL2, CCL2, CCL20, IL-17α and TNF-α mRNA were up-regulated in the HMP group (all P<0.05). HE staining revealed that the morphology of renal cells was normal in the Control group, whereas evident epithelial necrosis, cytoplasmic vacuolation, brush border loss and epithelial shedding were observed in the SCS group. Compared with the SCS group, pathological changes in the HMP group were alleviated. Conclusions HMP may activate renal inflammation, and inhibiting the activation of inflammation during HMP is expected to further improve the effect of allograft preservation.

Background/Aims: Existing hepatocellular carcinoma (HCC) prediction models are derived mainly from pretreatment or early on-treatment parameters. We reassessed the dynamic changes in the performance of 17 HCC models in patients with chronic hepatitis B (CHB) during long-term antiviral therapy (AVT). Methods: Among 987 CHB patients administered long-term entecavir therapy, 660 patients had 8 years of follow-up data. Model scores were calculated using on-treatment values at 2.5, 3, 3.5, 4, 4.5, and 5 years of AVT to predict threeyear HCC occurrence. Model performance was assessed with the area under the receiver operating curve (AUROC). The original model cutoffs to distinguish different levels of HCC risk were evaluated by the log-rank test. Results: The AUROCs of the 17 HCC models varied from 0.51 to 0.78 when using on-treatment scores from years 2.5 to 5. Models with a cirrhosis variable showed numerically higher AUROCs (pooled at 0.65–0.73 for treated, untreated, or mixed treatment models) than models without (treated or mixed models: 0.61–0.68; untreated models: 0.51–0.59). Stratification into low, intermediate, and high-risk levels using the original cutoff values could no longer reflect the true HCC incidence using scores after 3.5 years of AVT for models without cirrhosis and after 4 years of AVT for models with cirrhosis. Conclusions The performance of existing HCC prediction models, especially models without the cirrhosis variable, decreased in CHB patients on long-term AVT. The optimization of existing models or the development of novel models for better HCC prediction during long-term AVT is warranted.
