Traditional Chinese medicine(TCM) capable of clearing heat and removing toxin is most commonly used in clinical practice and has the effect of removing fire-heat and toxin. Studies have shown that most of the Ilex plants have the effect of clearing heat and removing toxin, among which the varieties of I. cornuta, I. pubescens, I. rotunda, I. latifolia, and I. chinensis are most widely used. These plants generally contain triterpenoids and their glycosides, alkaloids, flavonoids, phenylpropanoids, and other chemical components, especially pentacyclic triterpenoids. According to their skeletons, pentacyclic triterpenoids can be divided into the oleanane type, the ursane type, the lupinane type, etc. Among them, ursane-type components are the most abundant, and 136 species have been found so far. These components have been proved to have pharmacological effects such as anti-inflammatory, anti-tumor, hypolipidemic, anti-thrombosis, cardiomyocyte-protective, antibacterial, and hepatoprotective effects. Therefore, this paper systematically reviews the domestic and foreign literature on Ilex plants with a focus on the research progress on pentacyclic triterpenoids and their pharmacological activities, aiming to provide reference for the development of TCM resources with the effect of clearing heat and removing toxin.

Rice (Oryza sativa L.) is an important food crop. The appearance of lesion mimics in rice leads to phytohormone disorders, which affects rice adaptation to environmental stresses and ultimately reduces the yield and quality. To explore whether the changes in the adaptability of rice lesion-mimic mutants to stressful environments are caused by the disorder of phytohormone metabolism in plants. In this study, we screened an ethyl methane sulfonate-treated population of the japonica cultivar 'Taipei 309' for a mutant with rust-like spots on leaves at the early tillering stage and brown-red spots at maturity and named it rsl1 (rust spotted leaf 1). Compared with the wild type, rsl1 showed decreases in plant height, panicle length, primary branch number, secondary branch number, filled grains per panicle, seed-setting rate, and 1 000-grain weight, and an increase in number of effective panicles. Genetic analysis indicated that rsl1 was controlled by a single recessive nuclear gene. RSL1 was localized between two molecular markers, B7-7 and B7-9, on rice chromosome 7 by map-based cloning. PCR sequencing of the annotated genes in this interval revealed a mutation of C1683A on the eighth exon of SPL5 (LOC_Os07g10390) in rsl1, which resulted in premature termination of protein translation. Exogenous phytohormone treatments showed that rsl1 was less sensitive to salicylic acid (SA), abscisic acid (ABA), and indo-3-acetic acid (IAA) and more sensitive to methyl jasmonate (MeJA) and gibberellin acid (GA) than the wild type. In addition, the survival rate of rsl1 was lower than that of the wild type under salt, alkali, drought, and high temperature stresses, and it was higher than that of the wild type under cold stress. Quantitative real-time polymerase chain reaction (qRT-PCR) results showed that RSL1 was involved in the regulation of ABA, SA, MeJA, IAA, and GA-related genes under abiotic stresses. The present study showed that the RSL1 mutation led to the appearance of lesion mimics and affected the growth, development, and stress resistance of rsl1 under abiotic stresses. The study of the functional mechanism of this gene can provide theoretical guidance for the research on rice stress resistance.

Lipotoxicity is a pivotal factor that initiates and exacerbates liver injury and is involved in the development of metabolic-associated fatty liver disease (MAFLD). However, there are few reported lipotoxicity inhibitors. Here, we identified a natural anti-lipotoxicity candidate, HN-001, from the marine fungus Aspergillus sp. C1. HN-001 dose- and time- dependently reversed palmitic acid (PA)-induced hepatocyte death. This protection was associated with IRE-1α-mediated XBP-1 splicing inhibition, which resulted in suppression of XBP-1s nuclear translocation and transcriptional regulation. Knockdown of XBP-1s attenuated lipotoxicity, but no additional ameliorative effect of HN-001 on lipotoxicity was observed in XBP-1s knockdown hepatocytes. Notably, the ER stress and lipotoxicity amelioration was associated with PLA2. Both HN-001 and the PLA2 inhibitor MAFP inhibited PLA2 activity, reduced lysophosphatidylcholine (LPC) level, subsequently ameliorated lipotoxicity. In contrast, overexpression of PLA2 caused exacerbation of lipotoxicity and weakened the anti-lipotoxic effects of HN-001. Additionally, HN-001 treatment suppressed the downstream pro-apoptotic JNK pathway. In vivo, chronic administration of HN-001 (i.p.) in mice alleviated all manifestations of MAFLD, including hepatic steatosis, liver injury, inflammation, and fibrogenesis. These effects were correlated with PLA2/IRE-1α/XBP-1s axis and JNK signaling suppression. These data indicate that HN-001 has therapeutic potential for MAFLD because it suppresses lipotoxicity, and provide a natural structural basis for developing anti-MAFLD candidates.

AIM: To investigate the differences in varying stages of non-proliferative diabetic retinopathy(NPDR)using optical coherence tomography angiography(OCTA).METHODS: Cross-sectional study. A total of 77 cases(77 eyes)of diabetic patients were included, and they were divided into non-diabetic retinopathy(NDR; 23 eyes)and non-proliferative diabetic retinopathy(NPDR; 54 eyes)groups, further subdivided into mild NPDR(20 eyes), moderate NPDR(20 eyes), and severe NPDR(14 eyes). Foveal avascular zone(FAZ)area, superficial and deep capillary plexus densities(SSP and DSP), and visual acuity(LogMAR)were compared between NDR and NPDR groups. Furthermore, the visual acuity, FAZ area and levels of SSP and DSP were compared in different degrees of NPDR. Correlation analysis were conducted to elucidate relationships between FAZ area, visual acuity, SSP, DSP, and severity of the disease.RESULTS: Compared with the NDR group, the visual acuity(LogMAR)and macular FAZ area increased, while SSP and DSP were decreased in the NPDR group(P<0.05); there were significant differences in visual acuity, FAZ area and SSP and DSP levels in different degrees of NPDR(P<0.05). Visual acuity(LogMAR)and FAZ area displayed a positive correlation with the severity of disease, while SSP and DSP showed a negative correlation.CONCLUSION: With the progression of NPDR, the visual acuity(LogMAR)and FAZ area increased, and the SSP and DSP decreased.

Objective: To forecast mortality, age-standardized mortality, and probability of premature mortality from diabetes, and to simulate the impact of controlling risk factors by 2030 in China. Methods: We simulated the burden of disease from diabetes in six scenarios according to the development goals of risk factors control by the WHO and Chinese government. Based on the theory of comparative risk assessment and the estimates of the burden of disease for China from the Global Burden of Disease Study 2015, we used the proportional change model to project the number of deaths, age-standardized mortality, and probability of premature mortality from diabetes under different scenarios of risk factors control in 2030. Results: If the trends in exposures to risk factors from 1990 to 2015 continued. Mortality, age-standardized mortality, and probability of premature mortality from diabetes would increase to 32.57/100 000, 17.32/100 000, and 0.84% by 2030, respectively. During that time, mortality, age-standardized mortality and probability of premature mortality for males would all be higher than for females. If the goals of controlling risk factors were all achieved, the number of deaths from diabetes in 2030 would decrease by 62.10% compared to the predicted numbers based on the historical trends in exposure to risk factors, and the probability of premature mortality would drop to 0.29%. If only the exposure to a single risk factor were achieved by 2030, high fasting plasma glucose control would have the greatest impact on diabetes, resulting in a 56.00% reduction in deaths compared to the predicted numbers based on the historical trends, followed by high BMI (4.92%), smoking (0.65%), and low physical activity (0.53%). Conclusions: Risk factors control plays an important role in reducing the number of deaths, age-standardized mortality rate, and probability of premature mortality from diabetes. We suggest taking comprehensive measures to control relevant risk factors for certain populations and regions, to achieve the goal of reducing the burden of disease from diabetes as expected.

Objective:To investigate the short-term efficacy and safety of Donafenib as postoperative adjuvant therapy for patients with high risk of recurrence after radical resection of hepatocellular carcinoma (HCC).Methods:The propensity score matching (PSM) and retrospective cohort study was conducted. The clinicopathological data of 157 HCC patients with high risk of recurrence after radical resection who were admitted to 6 medical centers, including The First Affiliated Hospital of Nanjing Medical University et al, from June 2021 to February 2023 were collected. There were 128 males and 29 females, aged (59±10)years. Of 157 patients, 101 cases undergoing Donafenib as postoperative adjuvant therapy were divided into the the Donafenib group, and 56 cases under-going no systemic postoperative adjuvant therapy were divided into the control group. Observation indicators: (1) PSM and comparison of general data of patients between the two groups after matching; (2) postoperative treatment; (3) follow-up and survival of patients; (4) analysis of risk factors affecting recurrence-free survival of patients. PSM was done based on the principle of optimal perfect matching, with the clamp value of 0.5, and the Donafenib group and the control group were matched at a ratio of 1.25∶1. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range). Count data were described as absolute numbers and/or percentages, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Kruskal-Wallis H test. The Kaplan-Meier method was used to calculate survival rates and draw survival curves, and the Log-Rank test was used for survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Results:(1) PSM and comparison of general data of patients between the two groups after matching. Of 157 patients, 126 cases were successfully matched, including 70 cases in the Donafenib group and 56 cases in the control group, respectively. The elimination of tumor number confounding bias ensured comparability between the two groups after PSM. (2) Postoperative treatment. After PSM, of 70 patients in the Donafenib group, there were 23 cases receiving Donafenib monotherapy, 26 cases combined with transcatheter arterial chemoembolization (TACE), 14 cases combined with immunotherapy, and 7 cases combined with TACE+immunotherapy. Of 56 patients in the control group, there were 37 cases receiving postoperative follow-up alone and 19 cases combined with TACE. (3) Follow-up and survival of patients. All 157 patients were followed up, and the follow-up time of the 101 patients in Donafenib group and the 56 patients in control group were 10.1(range, 6.3-14.6)months and 22.2(range, 15.1-25.5)months, respectively. During the follow-up period, 70 patients in the Donafenib group experienced treatment-related adverse reactions, inclu-ding 8 cases of grade 3 adverse reactions, 23 cases of grade 2 and 39 cases of grade 1 adverse reactions, respectively. After PSM, the postoperative 12-, 18-month recurrence-free survival rates were 83.7%, 83.7% in the 70 patients of Donafenib group and 67.8%, 58.9% in the 56 patients of control group, respectively, showing a significant difference in the postoperative recurrence-free survival time between the two groups ( hazard ratio=0.395, 95% confidence interval as 0.176-0.888, P<0.05). (4) Analysis of risk factors affecting recurrence free survival of patients. Results of multivariate ana-lysis showed that microvascular invasion, vascular thrombus, clinical stage as ⅢA were independent risk factors affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=2.181, 2.612, 2.612, 95% confidence interval as 1.028-4.629, 1.128-6.047, 1.128-6.047, P<0.05), Donafenib as postoperative adjuvant therapy was an independent protective factor affecting recurrence-free survival in patients with high risk of recurrence after radical resection of HCC ( hazard ratio=0.457, 95% confidence interval as 0.227-0.920, P<0.05). Results of further analysis showed that after PSM, there were significant differences in the postoperative recurrence-free survival time in patients with different clinical factors, including male, age ≥60 years, tumor diameter >5 cm, positive microvascular invasion, positive hepatitis B virus infection, alpha fetoprotein <200 μg/L, between the Donafenib group and the control group ( hazard ratio=0.283, 0.202, 0.174, 0.345, 0.273, 0.180, 95% confidence interval as 0.114-0.707, 0.044-0.937, 0.038-0.794, 0.128-0.929, 0.091-0.819, 0.052-0.620, P<0.05). Conclusion:Donafenib as postoperative adjuvant therapy can effectively reduce the short-term recurrence rate in patients with high risk of recurrence after radical resection of HCC, with good safety and tolerance.
