Pathologic myopia(PM)is characterized by progressive axial elongation, posterior staphyloma, and fundus degenerative changes, representing a leading cause of blindness in Asian countries.Posterior scleral reinforcement(PSR)is currently the only surgical intervention to slow axial elongation. Its mechanisms involve mechanical reinforcement, improved blood circulation, and biological stimulation of scleral remodeling. This article reviews recent advances in PSR: surgical techniques have evolved from complex, classic procedures to standardized single-strip methods, incorporating 3D MRI to quantify posterior staphyloma morphology for personalized graft design and facilitating minimally invasive, precision surgery. Among implant materials, biomaterials such as allogeneic dura mater are being continuously optimized, while biomimetic piezoelectric smart materials actively promote scleral collagen synthesis through electrical signals, achieving a paradigm shift from “passive support”to “active reinforcement”. Clinical outcomes indicate advantages in regulating axial length, enhancing visual function and blood circulation, and facilitating early intervention in children. Combined procedures with ICL implantation, cataract surgery or vitrectomy provide comprehensive treatment regimens for individual patients with varied conditions. This article also analyzes long-term issues and core controversies including ectopic posterior staphyloma and reoperation, and prospects future research directions such as artificial intelligence assistance, translation of smart materials and full-cycle prevention and treatment systems, so as to provide references for clinical practice and scientific research.

Retinal vein occlusion(RVO), the second most common retinal vascular disease, is primarily caused by thrombosis or mechanical compression from adjacent arteries, leading to partial or complete venous obstruction. Emerging evidence suggests that inflammation plays a pivotal role in the pathogenesis of RVO. Various systemic inflammatory markers, such as NLR, SII, and PLR, have gained increasing attention due to their close association with the occurrence and clinical outcomes of RVO and secondary macular edema. Given their accessibility, low cost, and high reproducibility, these markers can serve as valuable adjuncts to ophthalmic imaging in assessing systemic inflammatory status and disease progression. This review systematically summarizes recent advances in systemic inflammatory markers for RVO, highlighting their associations with the occurrence, prognosis, and treatment response of RVO and macular edema. Furthermore, the limitations of current evidence were evaluated and outline future research directions were discussed, aiming to provide hematological adjunctive evidence for early risk identification and treatment monitoring in RVO.

OBJECTIVES: To investigate the protective mechanism of quercetin, the core component of Zuo Gui Wan, against Alzheimer's disease through the PI3K/AKT signaling pathway, based on network pharmacology, molecular docking, and cell experi-ments. METHODS: The active components of Zuo Gui Wan were identified by searching TCMSP, PubChem, Swiss Target Prediction, and BATMAN-TCM databases, and their potential targets were predicted. The target information was standardized using Uniprot, and Alzheimer's disease-related target genes were obtained from Drugbank, GeneCards, and OMIM. The intersection of these datasets was used to identify the potential targets of Zuo Gui Wan for treating Alzheimer's disease. Gene Ontology (GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed. The protein-protein interaction (PPI) network of potential targets was visualized using Cytoscape 3.10.1 software and the STRING database. The key active compounds and core potential targets for treating Alzheimer's disease with Zuo Gui Wan were identified through calculation. Based on the enrichment analysis results and literature, quercetin and the PI3K/AKT pathway were selected for verification. Molecular docking and binding ability prediction between quercetin and the core target AKT were performed using CB-Dock2, and visualization was conducted with AutoDock and PyMOL software. Finally, Aβ_1-42-induced HT-22 mouse hippocampal neuronal cells were used to construct an Alzheimer's disease cell model. Quercetin, the PI3K inhibitor LY294002, and the activator EGF were used as interventions. The groups were divided as follows: Control, Aβ_1-42, Aβ_1-42+Quercetin 2.5 μM, Aβ_1-42+Quercetin 5 μM, Aβ_1-42+Quercetin 10 μM, Aβ_1-42+EGF, and the PI3K/AKT modulation group: Control, LY294002, LY294002+Quercetin 10 μM, LY294002+EGF. CCK-8 assays were performed to detect cell viability, while JC-1, Calcein AM-PI, and Hoechst staining were used to assess cell apoptosis. Western blotting was employed to detect the expression of relevant target proteins. RESULTS: Network pharmacology and cell experiments collectively demonstrate that the key active ingredient of Zuo Gui Wan, quercetin, targets core proteins such as AKT1 and GSK3β through a network-based approach, significantly enriching the PI3K/AKT pathway. Molecular docking results indicate that quercetin has a strong binding affinity with AKT. Experimental validation in the Aβ_1-42 oligomer-induced HT-22 model reveals that quercetin significantly activates the PI3K/AKT signaling pathway, which is inhibited by Aβ_1-42 oligomers, as well as Bcl-2 protein expression. It also suppresses the expression of Cleaved Caspase 3/Caspase 3, BAX, and Cytochrome C proteins. JC-1, Hoechst 33342, and Calcein AM-PI staining results further show that quercetin can significantly alleviate apoptosis induced by Aβ_1-42 oligomers in HT-22 cells. Treatment with the PI3K inhibitor LY294002 in HT-22 cells leads to reduced cell viability and decreased expression of p-AKT/AKT and Bcl-2 proteins, while increasing the expression of Cleaved Caspase 3/Caspase 3, BAX, and Cytochrome C proteins. Additionally, apoptosis levels increase as observed in JC-1, Hoechst 33342, and Calcein AM-PI staining, all of which can be reversed by quercetin and the PI3K agonist EGF. CONCLUSIONS Quercetin, the key active ingredient of Zuo Gui Wan, exerts its protective effects against Alzheimer's disease by regulating the PI3K/AKT signaling pathway, inhibiting neuronal cell damage and apoptosis.

Age-related macular degeneration (AMD) is a disease that affects the vision of elderly individuals worldwide. Although current therapeutics have shown effectiveness against AMD, some patients may remain unresponsive and continue to experience disease progression. Therefore, in-depth knowledge of the mechanism underlying AMD pathogenesis is urgently required to identify potential drug targets for AMD treatment. Recently, studies have suggested that dysfunction of mitochondria can lead to the aggregation of reactive oxygen species (ROS) and activation of the cyclic GMP-AMP synthase (cGAS)/stimulator of interferon genes (STING) innate immunity pathways, ultimately resulting in sterile inflammation and cell death in various cells, such as cardiomyocytes and macrophages. Therefore, combining strategies targeting mitochondrial dysfunction and inflammatory mediators may hold great potential in facilitating AMD management. Notably, emerging evidence indicates that natural products targeting mitochondrial quality control (MQC) and the cGAS/STING innate immunity pathways exhibit promise in treating AMD. Here, we summarize phytochemicals that could directly or indirectly influence the MQC and the cGAS/STING innate immunity pathways, as well as their interconnected mediators, which have the potential to mitigate oxidative stress and suppress excessive inflammatory responses, thereby hoping to offer new insights into therapeutic interventions for AMD treatment.

Objective The high post-surgery recurrence rate of endometriosis(EMs)has emerged as a challenge in the long-term manaagement of the condition.This study is aimed at investigating the mechanisms of Neiyiting(NYT)decoction in preventing postoperative recurrence of EMs.Methods An animal model of EMs postoperative recurrence and a model of endometrial stromal cells(hEM15A)cocultured with macrophages(RAW 264.7 cell line)were established for both in vivo and in vitro experiments.An autotransplantation method was used to establish a rat model of EMs.The rats were divided into 4 groups(6 rats per group)and received the corresponding treatments:a Model group receiving distilled water,a Gestrinone group receiving gestrinone at 0.325 mg/kg,a low-dose NYT(NYT-L)group receiving NYT decoction at 5.04 g/(kg-d),and a high-dose NYT(NYT-H)group receiving NYT decoction at 10.08 g/(kg-d).The treatment was administered for 3 weeks via intragastric gavage.In addition,6 SD rats were randomly selected for the control group(Control group),and were given distilled water for 3 weeks via intragastric gavage.The sizes and pathological changes of recurrent lesions in EMs rats were observed.Immunohistochemistry and qRT-PCR were performed to assess the expression of M1 macrophage marker CD86 protein and mRNA in vivo.Additionally,immunohistochemistry and qRT-PCR were used to assess the expression of indicator proteins related to the triggering receptor expressed on myeloid cells 1(TREM1)/Toll-like receptor 4(TLR4)/nuclear factor kappa B(NF-κB)signaling pathway and mRNA.The proliferation of hEM15A cells in the coculture experiment was observed.Flow cytometry was performed to determine the polarization of RAW264.7 macrophages,and qRT-PCR was used to determine the expression levels of inducible nitric oxide synthase(iNOS)and interleukin 1β(IL-1β)mRNA.Western blot was performed to determine the expression of signaling pathway-related indicator proteins in vitro.ELISA was performed to determine the levels of inflammatory factors in vitro.Results Compared with the Model group,the volume of recurrent lesions in the NYT-H group was reduced(P＜0.01).Findings from the macrophage M1 polarization assessment showed that the expression levels of CD86 protein and mRNA in the recurrent lesions of the Model group were higher than those in the control group(P＜0.01).The expression levels of CD86 protein and mRNA in the recurrent lesions of the NYT-H group were lower than those of the Model group(P＜0.01).In addition,the RAW 264.7 cell experiment further verified that NYT decoction could reduce the number of CD86-positive macrophages induced by plasmids overexpressing TREM1 and reduce the expression of IL-1β and iNOS mRNA(P＜0.01).The results of the hEM15A cell proliferation assay showed that NYT decoction down-regulated KI-67 protein expression in hEM15A cells induced by macrophage M1 polarization(P＜0.01).The results of TREM1/TLR4/NF-κB signaling pathway showed that the protein and mRNA expression levels of TREM1,TLR4,and NF-κB in the recurrent lesions of the Model group were higher than those of the control group(P＜0.01).Compared with those in the Model group,the protein and mRNA expression levels of TREM1,TLR4,and NF-κB in the recurrent lesions of the NYT-H group were lower(P＜0.01).In addition,the coculture experiment of RAW264.7 and hEM15A cells further confirmed that NYT decoction reduced the expression of TREM1,TLR4,and P-P65 proteins(P＜0.01).Conclusion NYT decoction can inhibit macrophage M1 polarization through the TREM1/TLR4/NF-κB signaling pathway,improve the inflammation level,and inhibit the formation of ectopic endometrial lesions,thereby preventing postoperative recurrence of EMs.

Objective To conduct a reliability and validity analysis of the quantitative diagnostic criteria for hysterosalpingography(HSG)in clinical trials.Methods Questionnaire survey method was used for this study.A test questionnaire scale was constructed based on the imaging data of 10 patients who had received HSG.Fifteen medical workers engaged in HSG-related clinical and scientific research work were invited to score the test questionnaire according to quantitative diagnostic criteria.Internal consistency testing,correlation analysis,and exploratory factor analysis were used to evaluate the reliability and validity of the quantified diagnostic criteria.Results The overall Cronbach's α coefficient for this quantitative diagnostic criteria was 0.834.The Cronbach's α coefficients for the three evaluation functions,including tubal patency,tubal adhesion and pelvic adhesion,were 0.722,0.627 and 0.724 respectively.The Spearman-Brown split-half reliability coefficient was 0.859,and the Guttman split-half coefficient was 0.830.The inter-rater reliability measured by the Kendall W coefficient was 0.806(P＜0.05).The analysis indicated that the evaluation function for pelvic adhesion was suitable for factor analysis(KMO value=0.573,Bartlett Spherical test P=0.003).Two common factors were extracted(characteristic root being set at 1),and the cumulative variance interpretation rate was up to 74.74％.These factors were named as"items with low ambiguity"and"items with potential ambiguity"respectively.Conclusion The overall reliability and validity of this quantitative diagnostic criteria are satisfactory,it can meet the requirements of HSG-related clinical trials and has the potential for clinical promotion.

OBJECTIVE To investigate the induction of apoptosis in hepatocellular carcinoma cells by polyphyllin 9 （PP9） through the regulation of the Fas/Fas ligand （FasL） signaling pathway， and its inhibitory effect on the growth of transplanted tumor in nude mice. METHODS Based on the screening of cell lines and intervention conditions， HepG2 cells were selected as the experimental subject to investigate the effects of 2 μmol/L and 4 μmol/L PP9 treatment on cell colony formation activity， apoptosis rate， as well as the protein expressions of Fas， FasL， cleaved caspase-8 and cleaved caspase-3. Additionally， Fas inhibitor KR- 33493 was introduced to investigate the underlying mechanism of PP9’s anti-hepatocellular carcinoma activity. Using HepG2 cell tumor-bearing nude mice model as the object， and 5-fluorouracil （20 mg/kg） as the positive control， the effects of 10 mg/kg PP9 on tumor volume， tumor mass， and the protein expressions of the nuclear proliferation-associated antigen Ki-67 and cleaved caspase-3 in tumor-bearing nude mice were investigated. RESULTS Compared with the control group， 2， 4 μmol/L PP9 significantly decreased the number of clones and the clone formation rate of cells， but significantly increased the apoptosis rate， the protein expressions of Fas， FasL， cleaved caspase-8 and cleaved caspase-3 （P＜0.05 or P＜0.01）. However， the combination of Fas inhibitor KR-33493 could significantly reverse the effect of PP9 on the up-regulation of proteins related to the Fas/FasL signaling pathway （P＜0.01）. Compared with the control group， the tumor volume （on day 27）， mass and protein expression of Ki- 67 in nude mice of the PP9 group were significantly decreased， while the protein expression of cleaved caspase-3 was significantly increased （P＜0.01）. CONCLUSIONS PP9 can induce apoptosis of HepG2 cells by activating the Fas/FasL signaling pathway. Meanwhile， PP9 can also effectively inhibit the growth of transplanted tumors in nude mice.

Objective To investigate the clinical effect of far lateral approach surgery under unilateral biportal endoscope(UBE)for lumbar foraminal stenosis.Methods From June 2021 to August 2022,39 patients with lumbar foraminal stenosis were treated with far lateral approach surgery under UBE in our department.The patients were placed at the standard prone position,and a longitudinal line was drawn about 2 cm from the lateral edge of the upper and lower pedicles.Transverse incisions were made at the two intersection points of the horizontal line at the midpoint of the lateral edge of the upper and lower pedicles.After inserting the gradually enlarged sleeves to expand the space,the enlargement of the intervertebral foramen and release of the nerve root were completed under the direct view of UBE.The Visual Analogue Scale(VAS)of leg pain and the Oswestry Disability Index(ODI)were compared before and after operation.The effectiveness was evaluated according to the modified MacNab criteria at 12 months after operation.Results The operations were successfully completed in all the 39 cases.The operation time was(105.5±14.8)min,and the blood loss was(26.7±8.8)ml.The tear of adventitial nerve root occurred in 1 case during operation,and there was no nerve injury symptom after operation.One case of suspected infection occurred after operation and recovered after conservative treatment.All the 39 patients got out of bed with waist circumference on the first day after operation.The intervertebral foramen height measured by sagittal CT at 3 d after operation was(1.62±0.26)cm,which was significantly higher than that before operation[(1.51±0.28)cm;t=-4.010,P=0.000].The intervertebral foramen width was significantly greater than preoperation[(1.24±0.17)cm vs.(0.96±0.15)cm;t=-14.811,P=0.000].The area of intervertebral foramen was significantly larger than preoperation[(1.40±0.19)cm2 vs.(1.05±0.22)cm2;t=-12.874,P=0.000].The VAS of leg pain at 1 d,and 1,3,and 6 months after operation were significantly lower than those before operation(all P=0.000),and the VAS scores gradually decreased with the increase of time.The ODI was significantly lower at 1,3,and 6 months after operation than that before operation(all P=0.000),and the ODI decreased gradually with the increase of time.According to the modified MacNab criteria,at 12 months after operation,33 cases were excellent,4 cases were good,and 2 cases were fair,with an excellent and good rate of 94.9％(37/39).Conclusions Far lateral approach surgery under UBE for lumbar foraminal stenosis has significant effect on the relief of lumbago and leg pain and the improvement of lumbar function.It has little damage to lumbar stability and does not need internal fixation,which is worthy of clinical application and promotion.
