The traditional Chinese medicine prescription combination of Chrysanthemi Flos, Cassiae Semen, Lycii Fructus, Angelicae Sinensis Radix and Salviae Miltiorrhizae Radix et Rhizoma presents potential for treating retinal diseases.
Methodology: The researchers employed data mining to discern a new traditional Chinese medicine (TCM) prescription against retinal diseases and explore its medication rule. This was followed by constructing a network of TCMs, core ingredients, core targets, and core pathways using network pharmacology. The binding ability between core active ingredients and core targets was then verified through molecular docking and molecular dynamics simulation techniques.
Discussion: The novel TCM prescription screened in this study bears great potential in retinal diseases treatment through a unique mechanism of action. This mechanism involves TCM prescriptions that possess clearing heat and supplementing activities, associated with liver and lung meridians. The mechanism was found to act by modulating several core targets implicated in multiple core pathways such as the AGE-RAGE signaling pathway in diabetic complications, and the PI3K-Akt signaling pathway, among others. This potentially inhibits the inflammatory response, oxidative stress, and retinal neovascularization and apoptosis of retinal ganglion cells and retinal pigment epithelial cells. This improves retinal structural impairment and can have a significant impact on the treatment of retinal diseases.

Animal Study Cholesterol Chrysanthemum NAFLD
The researchers identified 14 compounds in the Jinsi Huangju tea using different spectroscopic techniques, 11 of which had not been previously identified in this plant. Two of these compounds, apigenin-7-O-6″-malonylglucoside and luteolin-7-O-6″-malonylglucoside, were synthesized for the first time with a yield of 1.2% over 5 steps.
In the findings, the natural compound apigenin-7-O-6″-malonylglucoside was found to inhibit the function of pancreatic lipase, reduce cellular lipid contents, and attenuate insulin resistance when tested in vitro. It was also observed to restore lipid and inflammatory profiles in plasma and the liver, as well as reduce hepatic steatosis in non-alcoholic fatty liver disease (NAFLD) mouse models. Thus, Jinsi Huangju and its active components are strong candidates for the development of drugs or functional foods that could provide a therapeutic strategy for hyperlipidaemia and NAFLD.
Chrysanthemum has several active ingredients that can potentially treat dry eye by inhibiting inflammation-related factors and pathways, thus reducing inflammation of lacrimal gland tissue.

Network Pharmacology Chrysanthemum Dry Eye
The study used network pharmacology methods and various databases to further analyze the mechanism of Chrysanthemum in treating dry eye. First, the TCMSP was used to screen for candidate active ingredient molecules of chrysanthemum showcasing requisite oral bioavailability and drug similarity. The active ingredients of chrysanthemum were then identified, followed by target prediction. Cytoscape was used to construct a compound-target network for chrysanthemum. The Online Mendelian Inheritance in Man and DisGeNET databases were utilized to pinpoint pathogenic genes associated with dry eye, and the STRING database produced an interaction network and bar graph to scrutinize protein interactions. Using Venny, a final drug-active ingredient-key target-disease network was created.
The study found that Chrysanthemum has eighty active ingredients corresponding to targets for treating dry eye. These key functional targets primarily regulate gene expression, oxidative stress, immune response, apoptosis, proliferation, regulation of cellular inflammation-related factors, and angiogenesis. The primary pathways associated with these key targets include interleukin signaling, metabolism, cytokine signaling in the immune system, immune system, and signal transduction, thereby improving the condition of dry eye primarily through the inhibition of inflammation-related factors.

Clinical Study Antioxidant Cholesterol Chrysanthemum
The researchers analyzed the composition of two types of Imperial Chrysanthemum (IC) extracts, specifically IC-P and IC-E, using an Ultra High-Performance Liquid Chromatography-Mass Spectrometry (UHPLC-MS) method. Next, they assessed these extracts' in vitro antioxidant activities using three different radical scavenging assays: 1,1-diphenyl-2-picrylhydraxyl (DPPH), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and Hydroxyl Radical(HR). A group of 37 adults followed a randomized program and were divided into two: one consuming a high-fat (HF) meal alone and the other having the same meal but supplemented with IC extract. Blood samples from participants were taken at a fasting state and several more times up to 8 hours after the meal.
The study found 12 compounds, including amino acids, flavonoids, and carboxylic acids, making up over 1% of the IC extracts. Compared to IC-E, IC-P exhibited significantly higher flavonoid content and strong free radical scavenging activity. Chrysanthemum consumption showed significant differences in post-meal glucose levels, triglycerides, total antioxidant capacity (T-AOC), and malondialdehyde (MDA) levels, with the IC-P supplement group showing lower postprandial glucose and improved serum antioxidant status.

Experimental Study Antioxidant Chrysanthemum
The study determined the antioxidant properties of Chrysanthemum morifolium by using methanol and ethyl acetate as solvents to extract and then analyse the plant's phenolic profile. The antioxidant activity was assessed with three separate in vitro tests: a reducing power assay, a Phosphomolybdenum antioxidative power assay, and the testing of inhibition of free radical 1,1-di phenyl-2-picryl hydrazyl. The content of total phenolics and total flavonoids was measured using the Folin Ciocalteu reagent, yielding a range of values.
In relation to the results, it was established that the examined plant was a significant source of bioactive compounds with notable antioxidant properties. A total of 29 phenolics, divided into 15 phenolic acids and 14 flavonoids were identified and quantified using high-performance liquid chromatography. Ellagic acid was the most present phenolic in the methanol extract and ethyl acetate fraction of green aerial parts. Meanwhile, Hesperidin was the most common flavonoid in the flower methanol extract. The ethyl acetate fraction from the flowers showed the highest efficiency in all tested antioxidant methods, indicating that different parts of the plant can vary in their antioxidant potential.

Experimental Study Goji Berry Retinitis Pigmentosa
The team carried out both in vivo and in vitro studies. Initially, mouse retinal ganglion cells were categorized into groups based on the doses of Lycium barbarum polysaccharide they were given and a positive drug control group. These cells were then subject to different H2O2 concentrations to induce apoptosis. Techniques such as flow cytometry, immunofluorescence, and western blot were used to evaluate cell viability, apoptosis rate, and expression of various markers. For in vivo research, the team used C57/BL6 and Rd10 mice divided into similar groups as the in vitro experiment. The mice underwent drug treatment for four weeks, after which their retina's response to light and general health were evaluated using an electroretinogram and histopathological examination.
The in vitro experiments showed that the apoptosis rate of ganglion cells significantly increased in the model group, along with up-regulation of certain proteins. However, a high dose of Lycium barbarum polysaccharide decreased the cell apoptosis rate and the levels of certain proteins. Similarly, in vivo testing showed that a high dose of the substance significantly aided in morphological alterations in a retina layer of Rd10 mice, and down-regulated the expression levels of a number of apoptosis-related proteins.
