Glaucoma， characterized by pathological elevation of intraocular pressure， progressive optic nerve damage， and apoptosis of retinal ganglion cells， is one of the leading causes of irreversible blindness. It is strongly associated with significant vision loss and a decline in quality of life. Although pharmacological therapy remains the primary approach to managing glaucoma， clinical outcomes are often suboptimal， highlighting the urgent need for safe and effective alternative treatments. In traditional Chinese medicine （TCM）， glaucoma is categorized as part of the "five wind internal obstruction" syndrome， and TCM has amassed substantial experience in the prevention and treatment of this condition. Therefore， this article provided a comprehensive review of recent findings on the relationship between glaucoma and relevant signaling pathways， as well as the regulatory effects of TCM on these pathways in the treatment of glaucoma. TCM can exert therapeutic effects by modulating key signaling pathways， including the Toll-like receptor 4/myeloid differentiation factor 88/nuclear factor-κB （TLR4/MyD88/NF-κB） signaling pathway， Janus kinase （JAK）/signal transducer and activator of transcription （JAK/STAT） pathway， phosphoinositide 3-kinase/serine-threonine protein kinase/mammalian target of rapamycin （PI3K/Akt/mTOR） pathway， nucleotide-binding oligomerization domain-like receptor protein 3 （NLRP3） inflammasome pathway， and nuclear factor erythroid 2-related factor 2/heme oxygenase-1 （Nrf2/HO-1） pathway. These pathways are involved in reducing inflammation， inhibiting apoptosis and ferroptosis， and ameliorating oxidative stress. By synthesizing current research， this article offers theoretical insights and practical references for advancing the understanding of the pathological mechanisms underlying glaucoma， innovating strategies for optic nerve protection， and promoting integrative TCM and Western medical approaches in glaucoma management.

Objective To explore the correlations of lumbar bone mineral density(BMD)and metabolic syndrome(MS)in adult males.Methods Data of low dose chest CT and quantitative CT of 13 490 adult males were retrospectively analyzed,and lumbar BMD were measured to judge whether MS existed and the degree of MS,and the correlations of lumbar BMD with MS or not and the degree of MS,as well as of lumbar BMD value and the related indicators of MS were assessed.Taken lumbar BMD as the dependent variable,the age,low density lipoprotein cholesterol(LDL-C),blood uric acid(BUA),hemoglobin(Hb)and MS or not were included in multiple linear regression analysis to observe the impact of MS and related indicators on lumbar BMD.Results Among 13 490 adult males,3 900 were found with MS(MS group),while 9 590 were found without MS(non-MS group).Significant difference of lumbar BMD was detected between groups(P=0.001).Lumbar BMD values were negatively correlated with MS(rs=-0.025,P=0.004)and the degree of MS(rs=-0.038,P＜0.001),whereas positively correlated with abdominal obesity,high triglyceride and low HDL-C or not(rs=0.024,0.061,0.036,all P＜0.001)but negatively correlated with hypertension and hyperglycemia or not(rs=-0.135,-0.104,both P＜0.05).After adjustment of age,lumbar BMD of adult males was negatively correlated with MS or not as well as LDL-C(both P＜0.05),but positively correlated with BUA and Hb(both P＜0.001).Conclusion Lumbar BMD was associated with MS in adult males.

Objective:To investigate the effects of personalized intermittent energy restriction (IER) diet on sleep related gut microbiome in obese patients.Methods:In this single-arm clinical trial, a total of 35 obese patients who visited Henan Provincial People′s Hospital from April to November 2018 were recruited as research subjects. They underwent a strict 32-day IER diet intervention, divided into 4 stages of 8 days each. Nutritional recipes were formulated and nutritious meals were provided to each obese patient with timed meals, including 55% carbohydrates, 15% protein, and 30% fat per meal. In stages 1, 2, 3, and 4, patients were provided with 2/3, 1/2, 1/3, and 1/4 of their previous calorie intake every other day, respectively, with meals at 8:00 and 16:00. During the remaining time, patients were allowed unrestricted eating at home. Physiological indicators (weight, body mass index, body fat percentage, waist circumference, hip circumference, fasting blood glucose, glycosylated hemoglobin, blood pressure, triglycerides, total cholesterol, high-density lipoprotein, low-density lipoprotein and Pittsburgh Sleep Quality Index (PSQI) scores were observed before and after the intervention. Gut microbiota changes were analyzed using metagenomic sequencing technology, and Spearman′s correlation analysis was used to assess the correlation between significantly different bacterial species and PSQI scores.Results:After the intervention, the body weight, body mass index, and PSQI scores of obese patients were all significantly lower than before intervention [(89.92±14.98) vs (97.53±15.67) kg, (31.94±3.95) vs (34.64±4.05) kg/m 2, (3.43±1.16) vs (5.42±2.27)], the abundance of gut microbiota was significantly higher after the intervention (all P<0.05). There were 45 significantly different bacterial species before and after the intervention, of which 6 bacterial species ( Enterobacter cloacae, Escherichia coli, Odoribacter splanchnicus, Oribacterium sinus, Streptococcus gordonii, and Streptococcus parasanguinis) showed significantly positive correlations with PSQI scores ( r=0.476, 0.475, 0.369, 0.391, 0.401, 0.423) (all P<0.05), and they were mainly enriched in the glutamate and tryptophan synthesis pathways. Conclusions:The personalized IER diet intervention can improve the sleep of obese patients while reducing weight, possibly mediated by changes in gut microbiota through the glutamate and tryptophan pathways.
