AIM: To observe the variation characteristics of postoperative optical coherence tomography(OCT), optical coherence tomography angiography(OCTA)examination indicators in patients with high myopia and macular hole retinal detachment(MHRD), and analyze their correlation with visual function.METHODS: A total of 78 MHRD patients with high myopia who were treated in the Baoding No.1 Central Hospital from January 2019 to October 2023 were selected as the study objects, all of which underwent vitrectomy combined with internal limiting membrane tamponade. The changes in the best corrected visual acuity(BCVA), OCT and OCTA parameters, including choriocapillary blood flow area(CBFA), diameter of ellipsoid zone absence(DEZA)and blood flow density were observed at 1, 3 and 6 mo after surgery. Pearson correlation analysis and multiple linear regression analysis were conducted to analyze the correlation between BCVA and CBFA, DEZA, and blood flow density at different time points after surgery.RESULTS: BCVA of enrolled patients at 1, 3, and 6 mo after surgery were 1.75±0.79, 1.49±0.53, and 1.08±0.44, respectively, and the differences at different points were statistically significant(all P<0.05). At 1, 3, and 6 mo after surgery, the patient's CBFA was 1.67±0.24, 1.82±0.13, and 1.94±0.15 mm2, respectively, the DEZA was 813.27±453.16, 590.89±421.38, and 427.58±385.34 μm, respectively, and the blood flow density was 24.36±7.81, 27.74±8.12, and 31.54±8.59, respectively. The differences in above indicators at different time points were statistically significant(all P<0.05). Pearson correlation analysis found that there was no significant correlation between DEZA, blood flow density and BCVA in patients with high myopia and MHRD at 1 mo after surgery(all P>0.05). However, CBFA was negatively correlated with BCVA(LogMAR; P<0.05); at 3 and 6 mo after surgery, CBFA and blood flow density were negatively correlated with BCVA(LogMAR)in patients with high myopia and MHRD, while DEZA was positively correlated with BCVA(LogMAR; all P<0.05). Multiple linear regression analysis showed that CBFA, blood flow density, and DEZA were important influencing factors of BCVA at 3 and 6 mo after surgery(all P<0.05).CONCLUSION:Visual function of patients with high myopia and MHRD gradually increases after surgery, and is closely related to postoperative CBFA, DEZA and blood flow density. It is recommended to regularly monitor changes in OCT and OCTA indicators after surgery.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by synovial inflammation, joint destruction, and functional impairment. Angiogenesis plays a key role in the pathological progression of RA with dysfunction of endothelial cells to promote synovial inflammation, sustain pannus formation, subsequently leading to joint damage. Colquhounia Root Tablets (CRT), a Chinese patent drug, has shown a satisfying clinical efficacy in treating RA, while the underlying mechanism by which CRT inhibits RA-associated angiogenesis remains unclear. In this study, we applied a research approach combining transcriptomic data analysis, bio-network mapping, and

AIM: To analyze the clinical utility and value of the ultra-wide-field swept-source optical coherence tomography angiography(UWF-SS-OCTA)technique in changes of blood flow density and thickness in the central and peripheral regions of the retina and choroid in patients with nonproliferative diabetic retinopathy(NPDR)with or without diabetic kidney disease(DKD).METHODS: Cross-sectional study. Totally 50 cases(50 eyes)of diabetes mellitus(DM)that visited our hospital between June 2023 and June 2024 were included. They were divided into three groups: NPDR combined with DKD group(DKD group, n=20), NPDR without DKD group(NDKD group, n=20), and DM without retinopathy group(DM group, n=10, which served as control). In order to investigate the impact of DKD on ocular microangiopathy in NPDR patients, the retina and choroid within 24 mm×20 mm of the scan were separated into central and peripheral areas using the 3×3 nine-grid partition option that comes with UWF-SS-OCTA, and the parameters were then quantitatively assessed.RESULTS:The central and peripheral blood flow density of the choroidal capillary layer(CCP)was statistically significant between the DM group and the DKD group(t=3.93, P=0.0003; t=3.34, P=0.0016), and between the NDKD group and the DKD group(t=-3.06, P=0.003; t=-2.55, P=0.013), but there was no statistically significant difference between the DM group and the NDKD group(t=1.44, P=0.157; t=1.26, P=0.21). The mid-large choroidal vessel(MLCV)showed a progressive decline in central and peripheral blood flow density in the DM, NDKD, and DKD groups(F=13.74, 19.03, all P<0.0001). The DM, NDKD, and DKD groups saw a progressive decrease in central and peripheral choroidal thickness(CT; F=10.72, P=0.0001; F=13.12, P<0.001).CONCLUSION:CCP, MLCV, and CT can be used as visual indicators to identify impaired renal function in patients with NPDR. UWF-SS-OCTA can support the development of precise and noninvasive monitoring and treatment technology for diabetic ocular microangiopathy, while also offering a scientific foundation for the joint management of DR and DKD.

The innate immune system detects cellular stressors and microbial infections, activating programmed cell death (PCD) pathways to eliminate intracellular pathogens and maintain homeostasis. Among these pathways, pyroptosis, apoptosis, and necroptosis represent the most characteristic forms of PCD. Although initially regarded as mechanistically distinct, emerging research has revealed significant crosstalk among their signaling cascades. Consequently, the concept of PANoptosis has been proposed—an inflammatory cell death pathway driven by caspases and receptor-interacting protein kinases (RIPKs), and regulated by the PANoptosome, which integrates key features of pyroptosis, apoptosis, and necroptosis. The core mechanism of PANoptosis involves the assembly and activation of the PANoptosome, a macromolecular complex composed of three structural components: sensor proteins, adaptor proteins, and effector proteins. Sensors detect upstream stimuli and transmit signals downstream, recruiting critical molecules via adaptors to form a molecular scaffold. This scaffold activates effectors, triggering intracellular signaling cascades that culminate in PANoptosis. The PANoptosome is regulated by upstream molecules such as interferon regulatory factor 1 (IRF1), transforming growth factor beta-activated kinase 1 (TAK1), and adenosine deaminase acting on RNA 1 (ADAR1), which function as molecular switches to control PANoptosis. Targeting these switches represents a promising therapeutic strategy. Furthermore, PANoptosis is influenced by organelle functions, including those of the mitochondria, endoplasmic reticulum, and lysosomes, highlighting organelle-targeted interventions as effective regulatory approaches. Cardiovascular diseases (CVDs), the leading global cause of morbidity and mortality, are profoundly impacted by PCD. Extensive crosstalk among multiple cell death pathways in CVDs suggests a complex regulatory network. As a novel cell death modality bridging pyroptosis, apoptosis, and necroptosis, PANoptosis offers fresh insights into the complexity of cell death and provides innovative strategies for CVD treatment. This review summarizes current evidence linking PANoptosis to various CVDs, including myocardial ischemia/reperfusion injury, myocardial infarction, heart failure, arrhythmogenic cardiomyopathy, sepsis-induced cardiomyopathy, cardiotoxic injury, atherosclerosis, abdominal aortic aneurysm, thoracic aortic aneurysm and dissection, and vascular toxic injury, thereby providing critical clinical insights into CVD pathophysiology. However, the current understanding of PANoptosis in CVDs remains incomplete. First, while PANoptosis in cardiomyocytes and vascular smooth muscle cells has been implicated in CVD pathogenesis, its role in other cell types—such as vascular endothelial cells and immune cells (e.g., macrophages)—warrants further investigation. Second, although pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) are known to activate the PANoptosome in infectious diseases, the stimuli driving PANoptosis in CVDs remain poorly defined. Additionally, methodological challenges persist in identifying PANoptosome assembly in CVDs and in establishing reliable PANoptosis models. Beyond the diseases discussed, PANoptosis may also play a role in viral myocarditis and diabetic cardiomyopathy, necessitating further exploration. In conclusion, elucidating the role of PANoptosis in CVDs opens new avenues for drug development. Targeting this pathway could yield transformative therapies, addressing unmet clinical needs in cardiovascular medicine.

ObjectiveTo investigate the effect and mechanism of Sishenwan in restoring the intestinal barrier function in the rat model of diarrhea-predominant irritable bowel syndrome (IBS-D) due to spleen-kidney Yang deficiency based on intestinal flora and short-chain fatty acids. MethodsAfter the delivery of 10 SPF-grade pregnant rats, 4 male suckling rats were kept in each litter for the experiment. The male suckling rats were randomly allocated into blank, model, low-dose (3.51 g·kg-1) Sishenwan, high-dose (7.02 g·kg-1) Sishenwan, and Peifeikang (0.54 g·kg-1) groups, with 8 rats in each group. The blank group was fed conventionally, and the other groups were subjected to mother-child separation and Sennae Folium gavage (1 g·mL-1, 10 mL·kg-1) for the modeling of IBS-D due to spleen-kidney Yang deficiency. After the modeling was completed, the rats in Sishenwan groups were administrated with the corresponding dose of Sishenwan decoction by gavage, and the Peifeikang group with bifidobacterium triple live powder+normal saline suspension. The blank and model groups were treated with an equal volume of normal saline by gavage. The general conditions and fecal characteristics of rats were observed. After 2 weeks of administration, the rats were anesthetized for sample collection. The pathological changes of the colon tissue in rats were observed by hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was employed to measure the levels of transforming growth factor-beta (TGF-β), interleukin-10 (IL-10), and interleukin-22 (IL-22). Immumohistochemical staining (IHC) was performed to detect the positive expression of zonula occludens-1 (ZO-1) and occludin in the colon tissue. Western blot was employed to determine the protein levels of ZO-1 and occludin in the colon tissue of rats, and 16S rRNA gene sequencing was performed for intestinal flora. Gas chromatography-mass spectrometry was employed to determine the content of short-chain fatty acids (SCFAs) in the cecum contents of rats. ResultsThe colon tissue in the blank group presented a clear structure, neat glands, and no inflammatory cell infiltration. In the model group, the colon tissue showcased a disorganized structure, irregular arrangement of glands, and inflammatory cell infiltration. Compared with the model group, the low-dose and high-dose Sishenwan groups and the Peifeikang group exhibited an intact colon tissue structure, regular arrangement of glands, and reduced inflammatory cell infiltration. Compared with the blank group, the modeling lowered the levels of TGF-β, IL-10, and IL-22 in the serum (P<0.01), down-regulated the protein levels of ZO-1 and occludin in the colon tissue (P<0.01), and decreased the content of acetic acid and propionic acid and increased the content of butyric acid in cecum contents (P<0.05). Compared with the model group, low-dose and high-dose Sishenwan raised the levels of TGF-β, IL-10, and IL-22 in the serum (P<0.05, P<0.01), and Peifeikang elevated the levels of TGF-β and IL-10 in the serum (P<0.01). High-dose Sishenwan and Peifeikang up-regulated the protein levels of ZO-1 and occludin (P<0.05, P<0.01), increased the content of acetic acid and propionic acid in cecum contents (P<0.05), and decreased the content of butyric acid (P<0.05). The 16S rRNA gene sequencing results showed that the intestinal flora structure of the model group changed compared with that of the blank group. Compared with the model group, Sishenwan and Peifeikang increased the relative abundance of Lachnospiraceae, Muribaculaceae, Akkermansiaceae, Ligilactobacillus, UBA3282, Akkermansia, and Corynebacterium while reducing the relative abundance of Oscillospiraceae, Desulfovibrionaceae, Lactobacillus, Romboutsia, and Desulfovibrio. They can restore the intestinal flora structure similar to that in the blank group. ConclusionSishenwan can alleviate diarrhea symptoms and colonic mucosal inflammation, increase the expression of tight junction proteins in the colonic mucosa, and strengthen the intestinal barrier in IBS-D rats with the syndrome of spleen-kidney Yang deficiency. The mechanism of action may be related to optimizing the structure and balance of intestinal flora and regulating the SCFAs, and the effect of high-dose Sishenwan is obvious.

In order to investigate whether the effect of Yuxuebi Tablets on the peripheral and central inflammation resolution of mice with inflammatory pain is related to their regulation of G protein-coupled receptor 37(GPR37), an inflammatory pain model was established by injecting complete Freund's adjuvant(CFA) into the paws of mice, with a sham-operated group receiving a similar volume of normal saline. The mice were assigned randomly to the sham-operated group, model group, ibuprofen group(91 mg·kg~(-1)), and low-, medium-, and high-dose groups of Yuxuebi Tablets(60, 120, and 240 mg·kg~(-1)). The drug was administered orally from days 1 to 19 after modeling. Von Frey method and the hot plate test were used to detect mechanical pain thresholds and heat hyperalgesia. The levels of interleukin-10(IL-10) and transforming growth factor-beta(TGF-β) in the spinal cord were quantified using enzyme-linked immunosorbent assay(ELISA), and the mRNA and protein expression of GPR37 in the spinal cord was measured by real-time quantitative reverse transcription PCR(qRT-PCR) and Western blot. Additionally, immunofluorescence was used to detect the expression of macrosialin antigen(CD68), mannose receptor(MRC1 or CD206), and GPR37 in dorsal root ganglia, as well as the expression of calcium-binding adapter molecule 1(IBA1), CD206, and GPR37 in the dorsal horn of the spinal cord. The results showed that compared with those of the sham-operated group, the mechanical pain thresholds and hot withdrawal latency of the model group significantly declined, and the expression of CD68 in the dorsal root ganglia and the expression of IBA1 in the dorsal horn of the spinal cord significantly increased. The expression of CD206 and GPR37 significantly decreased in the dorsal root ganglion and dorsal horn of the spinal cord, and IL-10 and TGF-β levels in the spinal cord were significantly decreased. Compared with those of the model group, the mechanical pain thresholds and hot withdrawal latency of the high-dose group of Yuxuebi Tablets significantly increased, and the expression of CD68 in the dorsal root ganglion and IBA1 in the dorsal horn of the spinal cord significantly decreased. The expression of CD206 and GPR37 in the dorsal root ganglion and dorsal horn of the spinal cord significantly increased, as well as IL-10 and TGF-β levels in the spinal cord. These findings indicated that Yuxuebi Tablets may reduce macrophage(microglial) infiltration and foster M2 macrophage polarization by enhancing GPR37 expression in the dorsal root ganglia and dorsal horn of the spinal cord of CFA-induced mice, so as to improve IL-10 and TGF-β levels, promote resolution of both peripheral and central inflammation, and play analgesic effects.

Panax species are mostly valuable medicinal plants. While some species' seeds are sensitive to dehydration, the dehydration tolerance of seeds from other Panax species remains unclear. The phospholipase D(PLD) gene plays an important role in plant responses to dehydration stress. However, the characteristics of the PLD gene family and their mechanisms of response to dehydration stress in seeds of Panax species with different dehydration tolerances are not well understood. This study used seeds from eight Panax species to measure the germination rates and PLD activity after dehydration and to analyze the correlation between dehydration tolerance and seed traits. Bioinformatics analysis was also conducted to characterize the PnPLD and PvPLD gene families and to evaluate their expression patterns under dehydration stress. The dehydration tolerance of Panax seeds was ranked from high to low as follows: P. ginseng, P. zingiberensis, P. quinquefolius, P. vietnamensis var. fuscidiscus, P. japonicus var. angustifolius, P. japonicus, P. notoginseng, and P. stipuleanatus. A significant negative correlation was found between dehydration tolerance and seed shape(three-dimensional variance), with flatter seeds exhibiting stronger dehydration tolerance(r=-0.792). Eighteen and nineteen PLD members were identified in P. notoginseng and P. vietnamensis var. fuscidiscus, respectively. These members were classified into five isoforms: α, β, γ, δ, and ζ. The gene structures, subcellular localization, physicochemical properties, and other characteristics of PnPLD and PvPLD were similar. Both promoters contained regulatory elements associated with plant growth and development, hormone responses, and both abiotic and biotic stress. During dehydration, the PLD enzyme activity in P. notoginseng seeds gradually increased as the water content decreased, whereas in P. vietnamensis var. fuscidiscus, PLD activity first decreased and then increased. The expression of PLDα and PLDδ in P. notoginseng seeds initially increased and then decreased, whereas in P. vietnamensis var. fuscidiscus, the expression of PLDα and PLDδ consistently decreased. In conclusion, the dehydration tolerance of Panax seeds showed a significant negative correlation with seed shape. The dehydration tolerance in P. vietnamensis var. fuscidiscus and dehydration sensitivity of P. notoginseng seeds may be related to differences in PLD enzyme activity and the expression of PLDα and PLDδ genes. This study provided the first systematic comparison of dehydration tolerance in Panax seeds and analyzed the causes of tolerance differences and the optimal water content for long-term storage at ultra-low temperatures, thus providing a theoretical basis for the short-term and ultra-low temperature long-term storage of medicinal plant seeds with varying dehydration tolerances.

This study investigated the therapeutic effects and mechanisms of Modified Yiyi Fuzi Baijiang Powder on ulcerative colitis(UC) in rats from the perspective of dampness. SD rats were randomly allocated into six groups(n=10): control, model, mesalazine, and Modified Yiyi Fuzi Baijiang Powder at low(3.96 g·kg~(-1)·d~(-1)), medium(7.92 g·kg~(-1)·d~(-1)), and high(15.84 g·kg~(-1)·d~(-1)) doses. UC was induced in all groups except the control by administration with 3% dextran sulfate sodium(DSS) solution for 7 days. The disease activity index(DAI) was recorded, and the colon tissue was collected for analysis. Histopathological changes were assessed by hematoxylin-eosin staining. Serum levels of D-lactic acid(D-LA) and diamine oxidase(DAO) were measured by ELISA. Immunohistochemistry and PCR were employed to evaluate the expression of aquaporins(AQP3, AQP4) and tight junction proteins [zonula occludens-1(ZO-1) and occludin] at both protein and mRNA levels. Compared with the control group, the model group showed an increased DAI scores(P<0.05), intestinal mucosal damage, elevated serum levels of DAO and D-LA(P<0.05), and decreased expression of AQP3, AQP4, ZO-1, and occludin(P<0.05). Treatment with Modified Yiyi Fuzi Baijiang Powder reduced the DAI scores(P<0.05), lowered the serum levels of D-LA and DAO(P<0.05), and upregulated the expression of AQP3, AQP4, ZO-1, and occludin at both protein and mRNA levels compared with the model group. These findings suggest that Modified Yiyi Fuzi Baijiang Powder exerts therapeutic effects on UC by reducing the intestinal mucosal permeability, promoting colonic mucosal repair, and regulating abnormal intestinal water metabolism, which may involve the upregulation of AQP3 and AQP4 expression.
