ObjectiveTo establish an ultra-performance liquid fingerprint and multi-components determination method for Naomaili granules. To evaluate the quality of different batches by chemometrics, and the anti-neuroinflammatory effects of water extract and main components of Naomaili granules were tested in vitro. MethodsThe similarity and common peaks of 27 batches of Naomaili granules were evaluated by using Ultra performance liquid chromatography (UPLC) fingerprint detection. Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) technology was used to determine the content of the index components in Naomaili granules and to evaluate the quality of different batches of Naomaili granules by chemometrics. LPS-induced BV-2 cell inflammation model was used to investigate the anti-neuroinflammatory effects of the water extract and main components of Naomaili granules. ResultsThe similarity of fingerprints of 27 batches of samples was > 0.90. A total of 32 common peaks were calibrated, and 23 of them were identified and assigned. In 27 batches of Naomaili granules, the mass fractions of 14 components that were stachydrine hydrochloride, leonurine hydrochloride, calycosin-7-O-glucoside, calycosin,tanshinoneⅠ, cryptotanshinone, tanshinoneⅡA, ginsenoside Rb1, notoginsenoside R1, ginsenoside Rg1, paeoniflorin, albiflorin, lactiflorin, and salvianolic acid B were found to be 2.902-3.498, 0.233-0.343, 0.111-0.301, 0.07-0.152, 0.136-0.228, 0.195-0.390, 0.324-0.482, 1.056-1.435, 0.271-0.397, 1.318-1.649, 3.038-4.059, 2.263-3.455, 0.152-0.232, 2.931-3.991 mg∙g-1, respectively. Multivariate statistical analysis showed that paeoniflorin, ginsenoside Rg1, ginsenoside Rb1 and staphylline hydrochloride were quality difference markers to control the stability of the preparation. The results of bioactive experiment showed that the water extract of Naomaili granules and the eight main components with high content in the prescription had a dose-dependent inhibitory effect on the release of NO in the cell supernatant. Among them, salvianolic acid B and ginsenoside Rb1 had strong anti-inflammatory activity, with IC50 values of (36.11±0.15) mg∙L-1 and (27.24±0.54) mg∙L-1, respectively. ConclusionThe quality evaluation method of Naomaili granules established in this study was accurate and reproducible. Four quality difference markers were screened out, and eight key pharmacodynamic substances of Naomaili granules against neuroinflammation were screened out by in vitro cell experiments.

ObjectiveTo screen suitable packaging and storage conditions for small packaged Alismatis Rhizoma decoction pieces, laying the foundation for developing standardized storage, maintenance techniques and determining shelf life. MethodsUsing the accelerated stability test method, the small packaged decoction pieces of Alismatis Rhizoma were placed in polyethylene plastic bags, aluminum foil polyethylene composite bags, and cowhide coated paper bags under temperature of (40±2) ℃ and relative humidity of (75±5)% conditions, the quality testing was conducted at the end of the 0th, 1st, 2nd, 3rd, and 6th month, respectively. Using long-term stability test method, an orthogonal experiment was designed to investigate storage conditions, packaging materials, and packaging methods. At the end of the 0th, 1st, 3rd, 6th, 9th, 12th, 18th, and 24th month, the quality of small packaged Alismatis Rhizoma decoction pieces was tested under different packaging and storage conditions(including 2 packaging methods:vacuum packaging and sealed packaging, 3 storage conditions:room temperature, cool, and modified atmosphere, 3 packaging materials:cowhide coated paper bag, aluminum foil polyethylene composite bag, and polyethylene plastic bag). Then, the G1-entropy weight method combined with orthogonal experiment was used to analyze the quality changes of the decoction pieces under different packaging and storage conditions to identify optimal packaging and storage conditions. The quality testing indicators for Alismatis Rhizoma decoction pieces were expanded beyond those specified in the 2020 edition of the Pharmacopoeia of the People's Republic of China. In addition to the existing indicators(characteristics, moisture content, extractives, and the total content of 23-acetyl alisol B and 23-acetyl alisol C), new indicators including color value, water activity, total triterpenoid content, and alisol B content have been added. ResultsThe accelerated stability test results indicated that the quality of small packaged Alismatis Rhizoma decoction pieces was more stable when packaged in aluminum foil-polyethylene composite materials compared to cowhide-coated paper bags and polyethylene plastic bags. Analysis of the long-term stability test results using the G1-entropy weight method combined with orthogonal experiment revealed that storage conditions had the greatest impact on both raw and salt-processed products, followed by packaging materials, while the packaging method had the least influence. For both types of small packaged Alismatis Rhizoma decoction pieces, modified atmosphere storage demonstrated superior efficacy compared to cool storage or room temperature storage. Storage in aluminum foil-polyethylene composite bags was superior to polyethylene plastic bags or cowhide-coated paper bags. However, the stability of sealed raw products was better than vacuum-packed ones, whereas vacuum-packed salt-processed products exhibited greater stability than their sealed counterparts. ConclusionBased on the results of the quality changes of small packaged Alismatis Rhizoma decoction pieces under different storage conditions, it is recommended that the suitable storage packaging conditions for small packaged raw products are sealed packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage, and the suitable storage and packaging conditions for small packaged salt-processed products are vacuum packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage.
3.Advances in the mechanisms of endothelial-to-mesenchymal transition in corneal endothelial cell
International Eye Science 2026;26(1):35-38
Corneal endothelial cells(CECs), which form the innermost cellular layer of the cornea, play a pivotal role in sustaining corneal transparency and preserving visual acuity. However, CECs are vulnerable to damage induced by a spectrum of pathological conditions or traumatic injuries. Once the density of CECs declines below a critical threshold, corneal endothelial dysfunction is precipitated, ultimately leading to corneal edema and progressive visual impairment. Penetrating keratoplasty and corneal endothelial transplantation remain the first-line therapeutic strategies for managing advanced corneal endothelial dysfunction. Nevertheless, the global shortage of donor corneas severely limits the accessibility and scalability of these surgical interventions. Consequently, regenerative medicine approaches targeting corneal endothelial repair and regeneration have emerged as a major focus of international research in ophthalmology. A key challenge in the in vitro expansion of CECs is their propensity to undergo endothelial-to-mesenchymal transition(EndMT). EndMT is a process of cellular phenotypic transformation, through which endothelial cells lose their intrinsic functions and acquire the characteristic features of mesenchymal cells. The EndMT significantly impedes the clinical translation of in vitro-cultured CECs for regenerative applications. In this review, the risk factors and related signaling pathways involved in EndMT were summarized, aiming to provide references for the basic research and clinical treatment of relevant diseases.
4.New advances in etiological diagnosis, prevention, and treatment of infectious keratopathy
International Eye Science 2026;26(1):39-44
Infectious keratitis(IK)is a major blinding eye disease worldwide. Early diagnosis and treatment are crucial for improving prognosis and reducing the economic burden. This article reviews advances in the diagnosis and treatment of IK, aiming to provide new insights for clinical management. In terms of diagnosis, in addition to conventional methods such as microbial culture and confocal microscopy, molecular diagnostic technologies—including high-throughput sequencing(NGS), CRISPR, and nanotechnology-based systems—have significantly enhanced the sensitivity and specificity of multiplex pathogen detection. These approaches are particularly valuable for identifying mixed infections and rare pathogens. Regarding treatment, in response to the growing challenge of drug resistance, novel drug delivery systems employing nanotechnology and bioactive dressings have markedly improved antibacterial efficacy by enhancing drug penetration and retention. Immunomodulatory therapy and photodynamic therapy effectively control inflammatory responses and improve outcomes. Integrated traditional Chinese and Western medicine, as well as microbiome-based therapies, have demonstrated significant advantages in reducing recurrence rates. Stem cell therapy offers new hope for repairing severe corneal damage, while gene therapy—through gene editing or transduction—strengthens the innate defense mechanisms of the cornea and reduces treatment-related side effects.

ObjectiveTo investigate the molecular mechanism by which Yifei Xuanfei Jiangzhuo prescription regulates the nuclear factor-κB (NF-κB)/NOD-like receptor protein 3 (NLRP3) signaling pathway to improve neuronal function in vascular dementia (VaD) rats. MethodsA VaD model was established by intermittently clamping the bilateral common carotid arteries (CCA) combined with bilateral vascular occlusion (2-VO). Eighty-four SD rats were randomly divided into a blank group, sham group, model group, piracetam group (0.2 g·kg-1), and low-, medium-, and high-dose Yifei Xuanfei Jiangzhuo prescription groups (6.09, 12.18, and 24.36 g·kg-1). Drug administration began on day 7 after surgery, once daily for 28 consecutive days. Behavioral experiments were used to evaluate learning and spatial memory. Hematoxylin-eosin (HE) staining was applied to observe pathological morphological changes in the CA1 region of the hippocampus. Transmission electron microscopy was used to examine the ultrastructure of hippocampal neurons. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) was used to detect neuronal apoptosis in the CA1 region. Immunohistochemistry was performed to determine the positive expression rate of neuronal nuclear antigen (NeuN). Immunofluorescence single staining was used to assess nuclear expression of NF-κB p65 in brain tissue. Western blot was used to detect the protein expression levels of inhibitor of κB kinase (IKK), NF-κB p65, NLRP3, Caspase-1, apoptosis-associated speck-like protein (ASC), and interleukin-1β (IL-1β). ResultsCompared with the blank group, the model group showed a significant reduction in platform-crossing frequency (P0.01), aggravated hippocampal injury, a significant increase in neuronal apoptosis (P0.05), decreased NeuN positivity in the CA1 region (P0.05), increased nuclear expression of NF-κB p65 (P0.05), and significantly elevated expression of p-IKK, p-NF-κB p65, NLRP3, cleaved Caspase-1, ASC, and cleaved IL-1β (P0.05). Compared with the model group, all drug-treated groups improved learning and spatial memory in VaD rats, alleviated hippocampal pathological injury and neuronal apoptosis, and protected neuronal ultrastructure. Yifei Xuanfei Jiangzhuo prescription at doses of 12.18 and 24.36 g·kg-1 reduced hippocampal expression levels of p-IKK, p-NF-κB p65, NLRP3, Caspase-1, ASC, and cleaved IL-1β in VaD rats (P0.05), showing dose-dependent inhibition of the NF-κB/NLRP3 signaling pathway. ConclusionYifei Xuanfei Jiangzhuo prescription may exert neuroprotective effects by regulating the NF-κB/NLRP3 signaling pathway, thereby reducing neuroinflammation and inhibiting hippocampal neuronal apoptosis.

ObjectiveTo observe the pharmacodynamic efficacy of phlorizin in improving hepatic glycolipid metabolism disorders in type 2 diabetic mellitus (T2DM) rats and to explore its mechanism of action based on the insulin receptor substrate-1 (IRS-1)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway. MethodsA high-fat diet and streptozotocin (STZ) were used to establish T2DM rat models. The rats were randomly assigned into six groups: the blank control group, model group, metformin group (300 mg·kg-1), and phlorizin high-dose (100 mg·kg-1) and low-dose groups (25 mg·kg-1). The rats were given intragastric administration for 6 weeks. The changes in body weight and fasting blood glucose (FBG) were observed, and the oral glucose tolerance test (OGTT) was carried out. The levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), glycated serum protein (GSP), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) in serum were detected by an automatic biochemical analyzer. The levels of fasting insulin (FINS), interleukin (IL)-1β, IL-6, and tumour necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay (ELISA). The levels of superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by the biochemical assays. The pancreas index, liver index, and insulin resistance index were calculated. Hematoxylin-eosin (HE) staining was used to evaluate the pathological changes in liver and pancreatic tissues. The immunofluorescence method was used to detect the changes in insulin and glucagon in pancreatic tissue. Western blot was used to detect the expression of related proteins in the IRS-1/PI3K/Akt pathway of liver tissue and its downstream glycogen synthase kinase-3β (GSK-3β) and forkhead box transcription factor O1 (FoxO1) proteins. ResultsCompared with the blank control group, the body weight of rats in the model group continued to decrease, while the FBG level increased significantly. The area under the OGTT blood glucose curve (AUC), GSP, TC, TG, LDL-C, IL-1β, IL-6, TNF-α, MDA, pancreatic index and liver index increased significantly, while the levels of HDL-C, SOD, and FINS decreased significantly (P0.05, P0.01). Histological results showed that the pancreatic islets of rats in the model group exhibited atrophy and severe structural abnormalities. The insulin-positive β-cells decreased significantly (P0.01), while the glucagon-positive α-cells increased significantly (P0.01). Inflammatory cell infiltration and partial necrosis were observed in the liver tissues of the model group rats. The expressions of p-IRS-1/IRS-1, p-GSK-3β/GSK-3β, and p-FoxO1/FoxO1 proteins in the liver of the model group increased significantly (P0.01), while the expressions of p-PI3K/PI3K and p-Akt/Akt proteins decreased significantly (P0.01). Compared with the model group, the diabetic symptoms of rats in all administration groups were improved. The changes in body weight and FBG were close to those of the blank control group. The levels of OGTT-AUC, GSP, TC, TG, LDL-C, MDA, IL-1β, IL-6, TNF-α and the pancreatic index, liver index were obviously reduced (P0.05, P0.01), while the levels of HDL-C, SOD, and FINS obviously increased (P0.05, P0.01). The pathological changes of the pancreas and liver in rats in all treatment groups were effectively improved. The insulin-positive β-cells in the pancreas increased significantly (P0.01), while the glucagon-positive α-cells decreased significantly (P0.01). The protein expressions of p-IRS-1/IRS-1, p-GSK-3β/GSK-3β, and p-FoxO1/FoxO1 in the liver were significantly reduced (P0.01), while the protein expressions of p-PI3K/PI3K and p-Akt/Akt significantly increased (P0.01). ConclusionPhlorizin reversed the weight loss and abnormal increase of FBG in T2DM rats, improved blood lipid profiles, oxidative stress, and inflammatory levels, alleviated insulin resistance, and had certain protective effects on the liver and pancreas. The hypoglycemic mechanism may involve regulating the IRS-1/PI3K/Akt signaling pathway to inhibit the activities of GSK-3β and FoxO1, thereby promoting liver glycogen synthesis and suppressing hepatic gluconeogenesis, ultimately improving glycolipid metabolism disorders.
