Background/Aims: Dysregulated cholesterol metabolism is a hallmark of hepatocellular carcinoma (HCC) that drives tumor initiation and progression. However, clinical targeting of cholesterol metabolism has yielded limited benefits due to stringent feedback in tumor cells. Identifying a central mediator capable of restoring cholesterol homeostasis within the cell’s intrinsically fine-tuned regulatory framework is urgently needed. Methods: We integrated a proteomic dataset from patients with cholesterol-dysregulated HCC into a global cholesterol metabolic regulatory network to identify potential therapeutic targets for disrupted cholesterol homeostasis. The prognostic significance of the candidate targets was further validated in an independent cohort through immunohistochemistry. Functional and mechanistic studies were conducted in vitro using HCC cell lines and in vivo using mouse models. The pharmacological efficacy of the candidate agent was evaluated in both subcutaneous and orthotopic HCC mouse models. Results: ER lipid raft-associated 1 (ERLIN1), a pivotal regulator of cholesterol metabolism reprogramming, was identified as an independent favorable prognostic indicator in HCC. ERLIN1 constrains HCC progression both in vitro and in vivo by stabilizing the INSIG1–SCAP–SREBP2 axis and maintaining the metabolic balance of intracellular cholesterol. Under hypoxia, impaired factor-inhibiting hypoxia-1-dependent hydroxylation of ASB11 at asparagine residues 90 and 92 enhances ASB11-mediated ERLIN1 degradation. Pharmacological targeting of this axis using zoledronic acid (ZoA) attenuated HCC progression by weakening the ASB11–ERLIN1 interaction and restoring cholesterol homeostasis. Conclusions ERLIN1 represents a druggable metabolic vulnerability in cholesterol-dysregulated HCC. Targeting the ASB11–ERLIN1 axis with the clinically approved ZoA reestablishes cholesterol homeostasis and offers a promising therapeutic strategy to overcome the current limitations of cholesterol-targeted HCC therapies.

Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations. Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits. Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01). Conclusion Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

Working memory is an executive memory process that includes encoding, maintenance, and retrieval. These processes can be modulated by transcranial alternating current stimulation (tACS) with sinusoidal waves. However, little is known about the impact of the rate of current change on working memory. In this study, we aimed to investigate the effects of two types of tACS with different rates of current change on working memory performance and brain activity. We applied a randomized, single-blind design and divided 81 young participants who received triangular wave tACS, sinusoidal wave tACS, or sham stimulation into three groups. Participants performed n-back tasks, and electroencephalograms were recorded before, during, and after active or sham stimulation. Compared to the baseline, working memory performance (accuracy and response time) improved after stimulation under all stimulation conditions. According to drift-diffusion model analysis, triangular wave tACS significantly increased the efficiency of non-target information processing. In addition, compared with sham conditions, triangular wave tACS reduced alpha power oscillations in the occipital lobe throughout the encoding period, while sinusoidal wave tACS increased theta power in the central frontal region only during the later encoding period. The brain network connectivity results showed that triangular wave tACS improved the clustering coefficient, local efficiency, and node degree intensity in the early encoding stage, and these parameters were positively correlated with the non-target drift rate and decision starting point. Our findings on how tACS modulates working memory indicate that triangular wave tACS significantly enhances brain network connectivity during the early encoding stage, demonstrating an improvement in the efficiency of working memory processing. In contrast, sinusoidal wave tACS increased the theta power during the later encoding stage, suggesting its potential critical role in late-stage information processing. These findings provide valuable insights into the potential mechanisms by which tACS modulates working memory.

Objective To investigate the epidemiological characteristics of knee osteoarthritis(KOA)among military personnel in plateau regions and to explore its risk factors.Methods From July 2023 to July 2024,a multi-stage stratified cluster random sampling method was employed to survey the prevalence of KOA and related risk factors among military personnel in the northwest plateau regions of China,covering different altitudes(1500-4500 m)and geographical areas(Gansu,Qinghai,Tibet,and Xinjiang).All study subjects were divided into KOA and non-KOA groups based on the presence or absence of KOA.Variables including age,gender,body mass index(BMI),education level,smoking status,military rank,military branch,service duration,regional altitude,annual average temperature,training duration,perceived training intensity,and history of knee injury were selected for univariate analyses between groups.Variables with P<0.05 in the univariate analyses were included in the binary multifactor logistic regression to identify risk factors for KOA.Results A total of 3000 questionnaires were distributed,and 2854 valid questionnaires were collected,with a response rate of 95.13%.The sample included 2584 males and 270 females,with 510 cases of KOA,resulting in a prevalence rate of 17.9%.Univariate analysis showed that there were statistically significant differences between KOA and non-KOA groups in terms of age,BMI,smoking status,military rank,military branch,service duration,regional altitude,annual average temperature,training duration,perceived training intensity,and history of knee injury(P<0.05).However,no significant differences were found in gender and education level(P>0.05).Binary multivariate logistic regression analysis revealed that older age(OR=1.382,P=0.017),higher BMI(P<0.01),smoking(OR=1.929,P<0.01),higher military rank(OR=1.485,P=0.007),being a member of the Armed Police(P<0.01),longer service duration(P<0.01),higher regional altitude(OR=1.459,P<0.01),lower annual average temperature(OR=1.188,P=0.001),longer training duration(P<0.01),higher perceived training intensity(OR=2.450,P<0.01),and history of knee injury(OR=2.768,P=0.002)were independent risk factors for KOA.Conclusions Older age,overweight/obesity,smoking,higher military rank,being a member of the Armed Police,longer service duration,higher altitude,cold climate,longer training duration,higher training intensity,and history of knee injury are independent risk factors for KOA among military personnel in the northwest plateau regions of China.

The thought of medicine and food homology and substances with both edible and medicinal values are an important part of China's excellent traditional culture and medicine treasure, playing an important role in human diet and health maintenance for thousands of years. Substances with both edible and medicinal values are a standardized name governed by existing regulations, and many substances with both edible and medicinal values in the list lack important information such as original plants and edible and medicinal parts. Some substances change as the relevant regulations change, which confuses the use and regulation. According to the definition and inclusion conditions of substances with both edible and medicinal values in the Regulation of Substances with Both Edible and Medicinal Values Catalogue, this paper comprehensively reviewed the first batch of 87 substances with both edible and medicinal values published in 2002 by collecting information and investigating the practical application. Some substances supplemented, deleted, and revised were analyzed and discussed, and a complete revised list was compiled, encompassing a total of 90 substances, which were when combined with the 19 substances of the last three batches(published in 2019, 2023, and 2024), amounted to a total of 109 substances. In addition, the substances not currently in the published list but have both edible and medicinal values according to the latest definition were summarized, which revealed at least 27 other substances. Therefore, there were at least 136 substances with both edible and medicinal values. Additionally, the potential substances that could be included in the list of substances with edible and medicinal values were prospected, providing a focus for future expansion of the list. This paper systematically reviewed and revised the list of substances with both edible and medicinal values to lay a foundation for the regulatory authorities to revise the catalog of these substances and provide basic information for promoting the new quality productive forces in the health field and boosting the orderly and rapid development of the big health industry.

Objective:To explore the relationship between corrected serum calcium level and clinical characteristics in patients with newly-diagnosed multiple myeloma (MM), as well as the influencing factors of concomitant hypercalcemia.Methods:A retrospective case cohort study was conducted. The clinical data of newly-diagnosed MM patients who were admitted to Shanxi Province Cancer Hospital from January 2020 to December 2023 were collected. When serum albumin (ALB) was less than 40 g/L, the serum calcium level was corrected. The hypercalcemia group was defined as the corrected serum calcium level >2.60 mmol/L, the normal blood calcium group was defined as 2.20-2.60 mmol/L, and the hypocalcemia group was defined as <2.20 mmol/L; the combination of normal blood calcium group and hypocalcemia group was the non-hypercalcemia group. The age, gender, immune typing, ALB, blood urea nitrogen (BUN), serum creatinine (Scr), β 2-microglobulin (β 2-MG), and alkaline phosphatase (ALP) of patients in the hypercalcemia group and the non-hypercalcemia group were compared. Pearson correlation analysis was used for the correlation analysis. The logistic regression model was used to conduct multivariate analysis on the influencing factors of hypercalcemia. Results:Before correction, there were 31 cases (26.5%), 48 cases (40.0%) and 38 cases (32.5%) of MM patients in the hypocalcemia group, normal blood calcium group and hypercalcemia group, respectively. After correction, there were 17 cases (14.5%), 58 cases (49.6%) and 42 cases (35.9%), respectively. The corrected serum calcium level for male MM patients was (2.58± 0.41) mmol/L, while for females it was (2.53±0.38) mmol/L, and there was no statistically significant difference between the two groups ( t = 0.79, P > 0.05). The corrected serum calcium levels for patients in stage Ⅰ, stage Ⅱ and stage Ⅲ of the International Staging System (ISS) were (2.31±0.15) mmol/L, (2.52±0.37) mmol/L and (2.65±0.42) mmol/L, respectively, and the difference between the three groups was statistically significant ( F = 53.62, P < 0.01). Corrected serum calcium showed a negative correlation with patients' serum ALB ( r = -0.201, P < 0.05), and positive correlations with Scr, BUN and β 2-MG levels ( r values were 0.470, 0.247 and 0.469, respectively, all P < 0.01), but it had no correlation with age or ALP ( r values were -0.013 and 0.078, respectively, both P > 0.05). There were 15 cases (17.1%), 48 cases (54.5%) and 25 cases (28.4%) of patients with normal renal function in the hypocalcemia group, normal blood calcium group and hypercalcemia group, respectively; there were 2 cases (6.9%), 10 cases (34.5%) and 17 cases (58.6%) of patients with impaired renal function in the hypocalcemia group, normal blood calcium group and hypercalcemia group, respectively; there were statistically significant differences between the hypocalcemia group and the hypercalcemia group, as well as between the normal blood calcium group and the hypercalcemia group ( χ2 = 4.57, P < 0.05; χ2 = 6.67, P < 0.05), but there was no statistically significant difference between the hypocalcemia group and the normal calcium group ( χ2 = 0.29, P>0.05). The patients with approximately normal bone status in the hypocalcemia group, normal blood calcium group and hypercalcemia group were 3 cases (13.0%), 17 cases (74.0%) and 3 cases (13.0%), respectively, and the patients with bone damage were 14 cases (14.9%), 41 cases (43.6%), and 39 cases (41.5%), respectively, and there was a statistically significant difference between the normal blood calcium group and the hypercalcemia group ( χ2 = 7.48, P < 0.01), while there was no statistically significant difference between the hypocalcemia group and the hypercalcemia group ( χ2 = 1.46, P > 0.05). The proportions of patients with Scr > 177 μmol/L and β 2-MG > 3.5 mg/L in the hypercalcemia group were higher than those in the non-hypercalcemia group, and the differences were statistically significant (both P < 0.05). The results of logistic regression multivariate analysis showed that β 2-MG >3.5 mg/L was an independent risk factor for hypercalcemia in newly-diagnosed MM patients ( OR = 1.178, 95% CI: 1.058-1.311, P = 0.003). Conclusions:Corrected serum calcium level may be an important indicator for evaluating the severity of disease, renal function and bone status in newly-diagnosed MM patients.
