ObjectiveTo explore the improving effect of Huangqi Chifengtang(HCT) on atherosclerosis(AS), and elucidate its mechanism in relation to adenosine monophosphate-activated protein kinase(AMPK)/peroxisome proliferator-activated receptor α(PPARα) signaling pathway and nucleotide-binding oligomerization domain(NOD)-like receptor thermal protein domain associated protein 3(NLRP3) inflammasome. MethodsEight C57BL/6J mice were set as the normal group, and 32 ApoE-/- mice were randomly divided into the model group, the positive drug group(atorvastatin, 5 mg·kg-1·d-1), HCT low- and high-dose groups(1.95, 3.90 g·kg-1·d-1). ApoE-/- mice were fed with high-fat and high-cholesterol feed to establish an AS mouse model. After modeling, they were orally administered corresponding dose of drugs for 28 days, while the normal and model groups received an equal volume of physiological saline via oral gavage. Hematoxylin-eosin(HE) staining was used to observe the pathological status of the aorta and liver in mice, Biochemical testing and enzyme-linked immunosorbent assay(ELISA) were used to detect the levels of total cholesterol(TC), triglycerides(TG), low-density lipoprotein cholesterol(LDL-C), alanine aminotransferase(ALT), aspartate aminotransferase(AST), C-reactive protein(CRP), interleukin(IL)-1β, IL-18 in the serum, as well as superoxide dismutase(SOD), malondialdehyde(MDA), and reduced glutathione(GSH) in the liver. Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR) was used to measure the mRNA expression levels of NLRP3, apoptosis-associated speck-like protein(ASC), cysteinyl aspartate specific proteinase-1(Caspase-1), Toll-like receptor 4(TLR4) in the aorta, and fatty acid synthase(FAS), stearoyl-CoA desaturase 1(SCD1), PPARα, and carnitine palmitoyltransferase 1A(CPT1A) in the liver. Immunohistochemistry was used to determine the protein expressions of NLRP3, Caspase-1, and ASC in the aorta, and Western blot was used to measure the protein expressions of AMPK, p-AMPK, sterol regulatory element binding protein-1c(SREBP-1c), CPT1A, and FAS in the liver. ResultsCompared with the normal group, the model group showed a significant increase in lipid plaque deposition in the aorta and lipid accumulation in the liver, the levels of TC, TG, LDL-C, AST, ALT, IL-1β, IL-18 and CRP in the serum were significantly increased(P<0.01), and the mRNA and protein expressions of aortic TLR4, NLRP3, Caspase-1 and ASC were significantly upregulated(P<0.01). The levels of SOD and GSH in the liver were significantly reduced, while the level of MDA was significantly increased(P<0.01). The mRNA expressions of FAS and SCD1 in the liver were significantly downregulated, while the mRNA expressions of PPARα and CPT1A were significantly upregulated. The protein expressions of p-AMPK/AMPK and CPT1A in the liver were significantly reduced, while the expressions of SREBP-1c and FAS proteins were significantly increased(P<0.01). Compared with the model group, the low- and high-dose HCT groups showed significant improvements in aortic plaques and hepatic lipid deposition. The levels of TC, LDL-C, AST, IL-1β and IL-18 in the serum of the low-dose HCT group, as well as TC, TG, LDL-C, AST, ALT, IL-1β, IL-18 and CRP in the serum of the high-dose HCT group, were significantly reduced(P<0.01). The mRNA expressions of TLR4, NLRP3 and Caspase-1 in the aorta of the low-dose HCT group, as well as TLR4, NLRP3, Caspase-1 and ASC in the aorta of the high-dose HCT group, were significantly downregulated(P<0.01). The protein expressions of Caspase-1 and ASC in the aorta of the low-dose HCT group, as well as NLRP3, Caspase-1 and ASC in the high-dose HCT group, were significantly downregulated(P<0.01). The levels of SOD and GSH in the liver of the low- and high-dose HCT groups were significantly increased, while the level of MDA in the high-dose HCT group was significantly decreased(P<0.05, P<0.01). In the HCT-treated group, the mRNA expressions of FAS and SCD1 in the liver were significantly upregulated, while the mRNA expressions of PPARα and CPT1A were significantly downregulated, the protein expressions of p-AMPK/AMPK and CPT1A in the liver were significantly increased, while the protein expressions of SREBP-1c and FAS were significantly decreased(P<0.05, P<0.01). ConclusionHCT can improve lipid metabolism by activating the AMPK/PPARα pathway and inhibit NLRP3 inflammasome-mediated inflammatory responses, thereby reducing hepatic lipid deposition and AS plaque formation.

ObjectiveTo investigate the value of different noninvasive diagnostic models in the diagnosis of esophageal and gastric varices since there is a high risk of esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension, and to provide a basis for the early diagnosis of esophageal and gastric varices. MethodsA total of 108 patients with significant portal hypertension due to compensated hepatitis B cirrhosis who attended Guangdong Provincial Hospital of Traditional Chinese Medicine from November 2017 to November 2023 were enrolled, and according to the presence or absence of esophageal and gastric varices under gastroscopy, they were divided into esophageal and gastric varices group (GOV group) and non-esophageal and gastric varices group (NGOV group). Related data were collected, including age, sex, imaging findings, and laboratory markers. The chi-square test was used for comparison of categorical data between groups; the least significant difference t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of five scoring models, i.e., fibrosis-4 (FIB-4), LOK index, LPRI, aspartate aminotransferase-to-platelet ratio index (APRI), and aspartate aminotransferase/alanine aminotransferase ratio (AAR). The binary logistic regression method was used to establish a combined model, and the area under the ROC curve (AUC) was compared between the combined model and each scoring model used alone. The Delong test was used to compare the AUC value between any two noninvasive diagnostic models. ResultsThere were 55 patients in the GOV group and 53 patients in the NGOV group. Compared with the NGOV group, the GOV group had a significantly higher age (52.64±1.44 years vs 47.96±1.68 years, t=0.453, P<0.05) and significantly lower levels of alanine aminotransferase [42.00 (24.00 — 17.00) U/L vs 82.00 (46.00 — 271.00) U/L, Z=-3.065, P<0.05], aspartate aminotransferase [44.00 (32.00 — 96.00) U/L vs 62.00 (42.50 — 154.50) U/L,Z=-2.351, P<0.05], and platelet count [100.00 (69.00 — 120.00)×109/L vs 119.00 (108.50 — 140.50)×109/L, Z=-3.667, P<0.05]. The ROC curve analysis showed that FIB-4, LOK index, LPRI, and AAR used alone had an accuracy of 0.667, 0.681, 0.730, and 0.639, respectively, in the diagnosis of esophageal and gastric varices (all P<0.05), and the positive diagnostic rates of GOV were 69.97%, 65.28%, 67.33%, and 58.86%, respectively, with no significant differences in AUC values (all P>0.05), while APRI used alone had no diagnostic value (P>0.05). A combined model (LAF) was established based on the binary logistic regression analysis and had an AUC of 0.805 and a positive diagnostic rate of GOV of 75.80%, with a significantly higher AUC than FIB-4, LOK index, LPRI, and AAR used alone (Z=-2.773,-2.479,-2.206, and-2.672, all P<0.05). ConclusionFIB-4, LOK index, LPRI, and AAR have a similar diagnostic value for esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension, and APRI alone has no diagnostic value. The combined model LAF had the best diagnostic efficacy, which provides a certain reference for clinical promotion and application.

The pathogenesis of central nervous system (CNS) diseases is complex, seriously affecting patients' physical and mental health and imposing a heavy economic burden on society. Western medicine shows limited efficacy in treating CNS diseases and is often associated with numerous adverse reactions and contraindications. Chinese medicine Lycii Fructus exhibits multiple pharmacological effects, including immune regulation, enhancement of hematopoietic function, liver protection, anti-tumor, hypoglycemic, antipyretic, anti-aging, and anti-radiation activities, and has gradually been applied in clinical treatment. In recent years, the active components of Lycii Fructus have attracted considerable attention for their potential therapeutic effects on CNS diseases. Studies indicate that these active components may exert neuroprotective effects through anti-inflammatory and antioxidant actions, inhibition of neuronal apoptosis, and repair of neuronal damage, involving multiple targets and pathways. This review summarizes the therapeutic effects of Lycii Fructus active components in CNS diseases over the past decade by searching PubMed, CNKI, Wanfang Data, and other electronic databases, aiming to provide new treatment strategies and insights for future research on Lycii Fructus in CNS disorders.

Cardiovascular disease (CVD), chronic kidney disease (CKD), and metabolic disorders are the 3 major chronic diseases threatening human health, which are closely related and often coexist, significantly increasing the difficulty of disease management. In response, the American Heart Association (AHA) proposed a novel disease concept of “cardiovascular-kidney-metabolic (CKM) syndrome” in October 2023, which has triggered widespread concern about the co-treatment of heart and kidney diseases and the prevention and treatment of metabolic disorders around the world. This review posits that effectively managing CKM syndrome requires a new and multidimensional paradigm for diagnosis and risk prediction that integrates biological insights, advanced technology and social determinants of health (SDoH). We argue that the core pathological driver is a “metabolic toxic environment”, fueled by adipose tissue dysfunction and characterized by a vicious cycle of systemic inflammation and oxidative stress, which forms a common pathway to multi-organ injury. The at-risk population is defined not only by biological characteristics but also significantly impacted by adverse SDoH, which can elevate the risk of advanced CKM by a factor of 1.18 to 3.50, underscoring the critical need for equity in screening and care strategies. This review systematically charts the progression of diagnostic technologies. In diagnostics, we highlight a crucial shift from single-marker assessments to comprehensive multi-marker panels. The synergistic application of traditional biomarkers like NT-proBNP (reflecting cardiac stress) and UACR (indicating kidney damage) with emerging indicators such as systemic immune-inflammation index (SII) and Klotho protein facilitates a holistic evaluation of multi-organ health. Furthermore, this paper explores the pivotal role of non-invasive monitoring technologies in detecting subclinical disease. Techniques like multi-wavelength photoplethysmography (PPG) and impedance cardiography (ICG) provide a real-time window into microcirculatory and hemodynamic status, enabling the identification of early, often asymptomatic, functional abnormalities that precede overt organ failure. In imaging, progress is marked by a move towards precise, quantitative evaluation, exemplified by artificial intelligence-powered quantitative computed tomography (AI-QCT). By integrating AI-QCT with clinical risk factors, the predictive accuracy for cardiovascular events within 6 months significantly improves, with the area under the curve (AUC) increasing from 0.637 to 0.688, demonstrating its potential for reclassifying risk in CKM stage 3. In the domain of risk prediction, we trace the evolution from traditional statistical tools to next-generation models. The new PREVENT equation represents a major advancement by incorporating key kidney function markers (eGFR, UACR), which can enhance the detection rate of CKD in primary care by 20%-30%. However, we contend that the future lies in dynamic, machine learning-based models. Algorithms such as XGBoost have achieved an AUC of 0.82 for predicting 365-day cardiovascular events, while deep learning models like KFDeep have demonstrated exceptional performance in predicting kidney failure risk with an AUC of 0.946. Unlike static calculators, these AI-driven tools can process complex, multimodal data and continuously update risk profiles, paving the way for truly personalized and proactive medicine. In conclusion, this review advocates for a paradigm shift toward a holistic and technologically advanced framework for CKM management. Future efforts must focus on the deep integration of multimodal data, the development of novel AI-driven biomarkers, the implementation of refined SDoH-informed interventions, and the promotion of interdisciplinary collaboration to construct an efficient, equitable, and effective system for CKM screening and intervention.

Ischemic stroke(IS) is a complex pathological process involving multiple cellular and molecular mechanisms and it is characterized by high mortality, high disability, and high recurrence. In recent years, the incidence of IS in China has been increasing year by year, and it has a trend of occurring in increasingly young individuals. Herb pairs are the smallest unit of traditional Chinese medicine(TCM) compatibility and an important part of TCM compounding, and the research on them is of great significance in guiding the clinical medication. Pharmacological studies have confirmed that certain herb pairs can exert anti-ischemic effects through various pathways such as reducing inflammation, alleviating oxidative stress, protecting the nervous system, and promoting neovascularization. By reviewing the relevant articles in the past decade, this paper probes into the combination rules, modern experimental studies, and combination ratios of the commonly used herb pairs from the etiology and pathogenesis of IS and summarizes 18 commonly used and deeply studied herb pairs, with a view to providing reference for the application, research, and development of clinical medicines.

AIM: To examine how three distinct central positioning techniques for anterior capsulotomy-pupil center, limbus center, and lens apex-affect intraocular lens(IOL)placement and visual quality following femtosecond laser-assisted cataract surgery(FLACS).METHODS: A total of 36 patients(72 eyes)with age-related cataracts who underwent FLACS and ZCB00 aspherical IOL implantation at Aier Eye Hospital Medical Center, Anhui Medical University between January and December 2023 were included in this prospective study. Patients were divided into three groups based on the central positioning mode for anterior capsulotomy: pupil center, limbus center, and lens apex center groups. IOL alignment and displacement were evaluated using the Casia2 device, and the postoperative visual quality was assessed.RESULTS: At 1 d postoperatively, the IOL tilt for the pupil, limbus, and apex groups were 3.96°±1.51°, 4.63°±1.87°, and 3.90°±2.24°, respectively(F=1.07, P=0.35); IOL decentration values were 0.21±0.10 mm, 0.23±0.16 mm, and 0.21±0.12 mm, respectively(F=0.14, P=0.87); total higher-order aberrations were 0.32±0.40 μm, 0.56±0.61 μm, and 0.53±0.60 μm, respectively(F=1.38, P=0.26); and coma aberrations values were 0.13±0.10 μm, 0.16±0.15 μm, and 0.14±0.15 μm, respectively(F=0.3, P=0.74). All results obtained postoperative day 1 did not differ significantly. At 3 mo postoperatively, IOL tilt values were 5.42°±2.00°, 3.96°±1.44°, and 3.20°±1.19°, respectively(F=12.40, P<0.001); IOL decentration values were 0.33±0.07 mm, 0.23±0.11 mm, and 0.21±0.11 mm, respectively(F=4.99, P=0.008); total higher-order aberrations were 0.67±0.29 μm, 0.44±0.37 μm, and 0.42±0.19 μm, respectively(F=5.50, P=0.006); and coma aberrations values were 0.21±0.12 μm, 0.19±0.12 μm, and 0.12±0.11 μm, respectively(F=3.87, P=0.03). All results obtained 3 mo postoperatively were statistically significant.CONCLUSION: Using the lens apex as the central positioning mode for anterior capsulotomy in FLACS improves postoperative IOL stability and reduces postoperative IOL tilt and decentration. If the lens apex cannot be determined intraoperatively, the limbus center-positioning mode is recommended.
10.Relationship between screening myopia and physical fitness index in college freshmen without majoring in public safety administration
Chinese Journal of School Health 2025;46(3):431-434
Objective:
To explore the relationship between visual acuity and physical fitness of university freshmen, so as to provide reference for myopia prevention and control for freshmen.
Methods:
From October to November 2022, 2 160 college freshman without majoring in public safety administration, selected from Guangxi Police College in 2022 by using the stratified cluster random sampling method, were reviewed for the results of visual acuity test and physical fitness scores. The physical fitness indices were evaluated by using the Z scores of physical fitness test scores, and the strength of association between the level of physical fitness index and myopia was analyzed by using Logistic regression model.
Results:
Among 2 160 college freshman without majoring in public safety administration, 917 (42.5%) students were diagnosed screening myopia, including 66 (3.1%) cases of high myopia, 383 (17.7%) cases of moderate myopia and 468 (21.7%) cases of mild myopia. The differences in the distribution of visual acuity tests among students with different physical fitness indices, body mass index, and gender were statistically significant ( Z/H=54.50, 49.53, 15.51, P <0.01). Low level and low middle level physical fitness indices were associated with screening myopia among freshmen[ OR (95% CI )=2.81(1.93-4.08),1.87(1.38-2.54)], and low level physical fitness indexes were associated with high myopia [ OR (95% CI )=7.22(2.33-22.32)] ( P <0.01).
Conclusions
Screening myopia among college freshman without majoring in public safety administration is related to physical fitness, and low level and low middle level physical fitness index are risk factors for myopia. Improving the level of physical fitness might be effective in preventing myopia.
