AIM:To compare the efficacy and safety of early combination therapy with ranibizumab and dexamethasone intravitreal implants versus ranibizumab monotherapy for the treatment of macular edema secondary to retinal vein occlusion(RVO-ME).METHODS: A retrospective cohort study was conducted on a total of 62 cases(64 eyes)of patients who were first diagnosed with RVO-ME at the Eye Centre of the Affiliated Hospital of Shandong Second Medical University between February 2022 and February 2023. The subjects were divided into two groups according to the different treatment regimens: 32 cases(34 eyes)in the monotherapy group received only ranibizumab [3+pro re nata(PRN)regimen], and 30 cases(30 eyes)in the combination therapy group were injected with ranibizumab once first, followed by dexamethasone intravitreal implant 3 wk later(1+DEX regimen). The best corrected visual acuity(BCVA), central retina thickness(CRT), foveal avascular zone(FAZ)area, macular vascular density(MVD)at the level of the deep vascular complex(DVC)of the retina, the incidence of ocular adverse effects, the number of drug injections, and the total cost between the two groups were compared before and after treatment.RESULTS: At 3 wk, 3 and 6 mo, and at the final follow-up of the two groups of patients, the improvement in BCVA, CRT, and MVD in the DVC layer was significantly better than that before treatment(all P<0.05); there were differences in the comparisons of BCVA and CRT between the two groups at 6 mo and the final follow-up(all P<0.05), and the increase in the number of letters of BCVA was the most pronounced in the combination therapy group at 6 mo of treatment. Statistical significant difference was observed in the comparison of MVD in the DVC layer between the two groups at 3 and 6 mo after treatment and at the final follow-up(all P<0.05). However, no significant change in FAZ area was evident before and after treatment in both groups(P>0.05). The combination therapy group exhibited a reduced number of injections and total cost in comparison to the monotherapy group. The combination therapy group exhibited a slightly higher incidence of high intraocular pressure and cataract progression compared to the monotherapy group, with no statistical significant difference(all P>0.05). Furthermore, no serious adverse events were observed in either group following treatment.CONCLUSION:Compared with ranibizumab alone, ranibizumab combined with dexamethasone intravitreal implant significantly improved vision, reduced macular edema, and lowered the frequency of injections and total treatment cost in patients with RVO-ME. CRT and MVD in the DVC layer are reliable prognostic indicators for patients with RVO-ME.

ObjectiveTo investigate the mechanism by which Anmeidan improves learning and memory in insomnia rats by regulating the cyclic guanosine monophosphate-adenosine monophosphate synthase （cGAS）/stimulator of interferon genes （STING） signaling pathway to influence immunoinflammation. MethodsSixty SD rats were randomly divided into a blank group， a model group， a suvorexant group （30 mg·kg^-1）， and Anmeidan low-， medium-， and high-dose groups （4.55， 9.09， and 18.18 g·kg^-1）， with 10 rats in each group. The insomnia rat model was induced by intraperitoneal injection of p-chlorophenylalanine （PCPA）. Anmeidan decoction and normal saline were administered by gavage for 28 days at the corresponding doses. Morris water maze and new object recognition tests were used to assess learning and memory functions. Hematoxylin-eosin （HE） staining and Nissl staining were performed to observe hippocampal cell morphology. Enzyme-linked immunosorbent assay （ELISA） was used to measure the serum levels of interleukin-1 （IL-1）， interleukin-1β （IL-1β）， interleukin-6 （IL-6）， interleukin-8 （IL-8）， interleukin-12 （IL-12）， interleukin-18 （IL-18）， and tumor necrosis factor-α （TNF-α）. Western blot and Real-time quantitative polymerase chain reaction（Real-time PCR） were used to detect the relative protein and mRNA expression levels of hippocampal cGAS and STING. ResultsCompared with the blank group， the 5-HT content in the model group was significantly reduced （P<0.01）. The latency to the upper platform and total distance were significantly increased （P<0.05， P<0.01）， while the residence time in the target quadrant and the number of platform crossings were significantly reduced （P<0.01）， and the relative recognition index for new objects was significantly lower （P<0.01）. The morphology and arrangement of hippocampal neurons were loose and disordered， with a decreased number of intracellular Nissl bodies. The relative expression levels of IL-1， IL-1β， IL-6， IL-8， IL-12， IL-18， TNF-α， cGAS， and STING pathway proteins and mRNA were significantly upregulated （P<0.01）. Compared with the model group， the latency to the upper platform in the high-dose Anmeidan group was significantly shortened （P<0.05）. In the medium- and high-dose Anmeidan groups and the suvorexant group， the residence time in the target quadrant and the number of platform crossings were significantly increased （P<0.01）. The total distance traveled was significantly reduced （P<0.01）， and the relative recognition index for new objects was significantly increased （P<0.01）. The hippocampal neurons were more neatly arranged， and the number of intracellular Nissl bodies increased. The expression of IL-1， IL-1β， IL-6， IL-8， IL-12， IL-18， TNF-α， and cGAS proteins and mRNA in the medium- and high-dose Anmeidan groups was significantly downregulated （P<0.05， P<0.01）. ConclusionAnmeidan improves learning and memory in insomnia rats， possibly by suppressing immunoinflammation through inhibition of the cGAS/STING signaling pathway.

ObjectiveTo investigate the differences in efficacy and endogenous metabolic mechanisms of Anmeidan with combined use of raw and fried Ziziphi Spinosae Semen and its disassembled prescriptions in treating anxiety and cognitive impairment in insomnia rats. MethodsSixty rats were randomly divided into six groups （n=10 per group）： blank group， model group， suvorexant group （30 mg·kg^-1）， Anmeidan group （9.09 g·kg^-1）， Anmeidan with absence of raw Ziziphi Spinosae Semen group （7.38 g·kg^-1）， and Anmeidan with absence of fried Ziziphi Spinosae Semen group （7.38 g·kg^-1）. An insomnia model was constructed by intraperitoneal injection of para-chlorophenylalanine （PCPA）， followed by gavage administration of Anmeidan or its disassembled prescriptions. Anxiety levels were assessed using the open field test， while cognitive ability was evaluated via the novel object recognition test. The pathological morphology of hippocampal neurons was examined using electron microscopy. Serum samples were analyzed by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry （UPLC-Q-TOF-MS） for principal component analysis， metabolic profiling， identification of differential metabolites， and metabolic pathway analysis. ResultsCompared with the blank group， the model group exhibited significantly increased exercise mileage， exercise time， and the ratio of the number of entries into the peripheral zone to the total number of entries into both the peripheral and central zones exhibited a marked increase （P<0.05， P<0.01）， while the novel object recognition index significantly decreased （P<0.05）. Compared with the model group， the Anmeidan and suvorexant groups showed significantly reduced exercise mileage and exercise time （P<0.01）. The ratio of the number of entries into the peripheral zone to the total number of entries into both the peripheral and central zones decreased （P<0.05）， and a significant increase in the novel object recognition index （P<0.01）. However， the disassembled prescription groups showed no significant improvement in open field test and novel object recognition test indices. Electron microscopy revealed that the Anmeidan group improved the pathological morphology of hippocampal neurons in insomnia rats. Metabolomics analysis identified 10 potential differential metabolites associated with Anmeidan's therapeutic effects， involving metabolic pathways related to phenylalanine and tryptophan biosynthesis and metabolism， as well as the serotonergic pathway. ConclusionThe combined use of raw and fried Ziziphi Spinosae Semen in Anmeidan is more effective than its disassembled prescriptions in alleviating anxiety and cognitive impairment in PCPA-induced insomnia rats. The underlying mechanism may be associated with metabolic pathways related to phenylalanine， tryptophan， and serotonin.

ObjectiveTo elucidate the potential mechanisms by which the classic prescription Anmeidan alleviates cognitive impairment in insomnia model rats through metabolic profiling. MethodsA total of 60 SD rats were randomly divided into six groups： blank group， model group， low-， medium-， and high-dose Anmeidan groups， and the Suvorexant group， with 10 rats in each group. Except for the blank group， the insomnia model was established in all other groups via intraperitoneal injection of para-chlorophenylalanine. The Suvorexant group was administered Suvorexant solution （30 mg·kg^-1·d^-1） by gavage， while the low-， medium-， and high-dose Anmeidan groups received Anmeidan decoction （4.55， 9.09， 18.18 g·kg^-1·d^-1） by gavage. The blank group received an equivalent volume of normal saline. The open field test was used to assess spatial exploration and anxiety/depressive-like behaviors in rats. Serum levels of epidermal growth factor （EGF）， brain-derived neurotrophic factor （BDNF）， and vasoactive intestinal peptide （VIP） were measured using enzyme-linked immunosorbent assay （ELISA）. Untargeted metabolomics was employed to identify differential metabolites in rat serum， and systematic biological methods were applied to analyze the potential targets and pathways of Anmeidan. ResultsCompared to the blank group， the model group exhibited significant reductions in total distance traveled， average speed， number of entries into the central area， time spent in the central area， and frequency of upright events （P<0.01）， along with significant decreases in VIP， EGF， and BDNF levels （P<0.05，P<0.01）. A total of 100 differential metabolites were identified between the model and blank groups. Compared to the model group， the low-， medium-， and high-dose Anmeidan groups showed significant increases in total distance traveled， average speed， number of entries into the central area， time spent in the central area， and frequency of upright events （P<0.05，P<0.01）， as well as a significant increase in VIP levels （P<0.05，P<0.01）. Anmeidan significantly reversed abnormal changes in 67 metabolites compared to the model group. A combined analysis identified 134 potential targets of Anmeidan， with network topology analysis suggesting that Caspase-3， B-cell lymphoma 2 （Bcl-2）， nuclear transcription factor-κB （NF-κB）， interleukin-1β （IL-1β）， interleukin-2 （IL-2）， matrix metalloproteinase-9 （MMP-9）， and Toll-like receptor 4 （TLR4）， among others， may serve as key targets of Anmeidan. Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway analysis revealed major enriched pathways， including the cyclic adenosine monophosphate （cAMP） signaling pathway， hypoxia inducible factor-1 （HIF-1） signaling pathway， and IL-17 signaling pathway. ConclusionThis study demonstrates that Anmeidan can recalibrate abnormal metabolic profiles in insomnia model rats to mitigate cognitive impairment， with its mechanisms of action potentially involving the regulation of immune-inflammatory responses， energy metabolism， and apoptosis-related pathways.
