Licochalcone E is a chalcone isolated from Glycyrrhiza uralensis and G. inflata Batal. This study explored the effect of licochalcone E on improving hepatic steatosis in obese mice and evaluated the role of licochalcone E in regulating lipid accumulation in hepatocytes. In vitro, oleic acid–induced hepatocytes were treated with licochalcone E to investigate its effect on lipid metabolic pathways. In animal experiments, male C57BL/6 mice were fed with a high-fat diet (HFD) and treated with licochalcone E by intraperitoneal injection for 12 weeks to assess its effects on biochemical indexes and hepatic steatosis. Furthermore, mice were fed a methionine/choline-deficient (MCD) diet and administered licochalcone E, followed by evaluation of liver fibrosis. Licochalcone E effectively reduced body weight, epididymal and inguinal fat weight, and adipocyte size in HFD-induced obese mice. Licochalcone E treatment of obese mice also reduced hepatic lipid accumulation and improved hepatocyte steatosis. Licochalcone E regulated the expression of lipogenesis- and lipolysis-related genes in the livers of obese mice and increased AMPK phosphorylation and Sirt1 expression in the liver. Licochalcone E also attenuated hepatic inflammation and oxidative stress in obese mice. Furthermore, treatment of MCD-induced mice with licochalcone E reduced the number of lipid vacuoles and the extent of fibrosis and inhibited liver inflammation. In FL83B hepatocytes, licochalcone E could regulate lipogenesis and lipolysis, and increase the phosphorylation of AMPK and ACC. These findings provide new insights into the role of licochalcone E in regulating lipid metabolism and preventing hepatic steatosis.

Clinical and Experimental Pediatrics 2026;69(4):322-329
Background:
Patients with coarctation of the aorta (CoA) and an interrupted aortic arch (IAA) may present with small mitral valves (MVs) and a reduced left ventricular (LV) volume. Biventricular repair (BVR) in these patients is dependent on adequate size of the left cardiac structures.Purpose: This study evaluated the impact of the hemodynamic characteristics of atrial septal defects (ASDs) on MV growth following surgical repair.
Methods:
We retrospectively reviewed the data of patients diagnosed with CoA or IAA between 2007 and 2024. The z score for MV size measured 6 months postoperatively (Z2) was compared with the preoperative MV size (Z1). The factors associated with MV growth were also studied.
Results:
A total of 161 patients with CoA or IAA were included. Transthoracic echocardiography was used to assess the MV and LV dimensions preoperatively and 6 months postoperatively. Of the cohort, 155 (96.3%) underwent initial BVR and 6 underwent single-ventricle palliation. MV z scores significantly increased following BVR (mean change: +0.45±1.35; P<0.001) but decreased after single-ventricle repair (-0.56±0.49, P=0.04). Multivariate analysis identified the initial MV z score and ASD pressure gradient as independent predictors of MV growth (R2=0.39).
Conclusion
Annular growth of the MV was not observed in patients who underwent single-ventricle palliation. In contrast, among patients who achieved BVR, those with a small preoperative MV annulus and low ASD pressure gradient demonstrated subsequent catch-up MV growth, suggesting that adequate left-sided preload is essential for MV development.

Background:
This study examines whether stronger corporate governance is associated with workplace mental health practices and whether this relationship is mediated by a structured sequence of occupational safety and health (OSH) engagement: recognition, goal-setting, and implementation.
Methods:
We analyzed 134 listed companies in Taiwan that published sustainability reports and received corporate governance evaluations between 2014 and 2023. Governance scores―based on shareholder rights, board functioning, transparency, and sustainability―were dichotomized into high vs. low categories. Workplace mental health practices were measured using 24 binary indicators across planning, provision, and reporting. OSH engagement was conceptualized in three stages based on Global Reporting Initiative 403 guidelines, with composite indicators derived via grouped weighted quantile sum regression. Associations were analyzed using generalized linear mixed-effects and serial mediation models.
Results:
Compared to companies ranked low in corporate governance, those ranked high had a higher likelihood of adopting mental health practices. OSH goal-setting and implementation showed significant positive associations, whereas recognition did not. Serial mediation analysis showed that 83% of the total effect of corporate governance on mental health practices was direct, while 17% was mediated through structured OSH engagement, primarily via implementation. Recognition showed a nonsignificant effect but initiated significant sequential pathways via goal-setting and implementation.Goal-setting functioned as a bridge within these chains.
Conclusion
Corporate governance plays a central role in advancing workplace mental health practices.While most effects are direct, structured OSH engagement helps translate governance priorities into sustained organizational actions that embed mental health into routine practice.

Introduction:
Repaglinide, a meglitinide analogue, has a rapid onset
and short duration of action. It offers prandial glucose
control while reducing hypoglycemia risk compared to
sulfonylureas. We describe its use in our special cohorts
of diabetic patients where repaglinide was prescribed to
reduce hypoglycemia in vulnerable patients or to optimize
glycemic control through pharmacotherapy intensification
or deintensification.
Cases:
Cohort A comprised 12 elderly patients with multiple
comorbidities (mean age: 70.3 years; mean DM duration:
18.3 years) characterized by high glucose variability and
problematic hypoglycemia. In seven patients, low-dose
gliclazide was replaced with repaglinide with reduction
in hypoglycemic episodes. One patient on low-dose premixed insulin was successfully switched to preprandial
repaglinide. Two patients on basal insulin were able to
reduce their insulin requirements and stabilize their glucose
levels. A younger patient with autonomic dysfunction had
hypoglycemia while on insulin glulisine, while its omission
led to severe hyperglycemia. Substituting glulisine with
repaglinide resolved the glucose variability. Repaglinide
effectively reduced hypoglycemic episodes while maintaining glycemic stability, with a mean hemoglobin A1c
(HbA1c) reduction of 0.36% over 3–6 months.
Cohort B consisted of six younger patients (mean age: 35.3
years) with focus on optimizing HbA1c and improving
treatment adherence. Two patients on basal-bolus regimes
success-fully transitioned off bolus insulin to repaglinide,
significantly improving compliance. One patient on
basal insulin was successfully transitioned to an all-oral
regimen. Three patients on existing oral hypoglycemic
agents were started on repaglinide to close the glycemic
gap. Cohort B achieved a robust mean HbA1c reduction of
2.1% within 3–6 months.
Conclusion
Repaglinide remains an important armamentarium in
personalized diabetes management. Its pharmacokinetics
and flexible dosing allow intensification of glycemic
control while minimizing the risk of hypoglycemia. It also
offers a viable strategy for selected patients struggling
with complex insulin regime.

Objective This study reports on the obligatory parasitism of water mites Arrenurus sp. on Anopheles messeae at the Manzhouli Port, Inner Mongolia, China. Methods Duing July 2024, a survey on the mosquito diversity was conducted at the Manzhouli Port. Captured mosquitoes and their ectoparasites were identified to species level. Results A total of 1840 adult mosquitoes were collected, representing species from three genera: Culex(Cx. modestus, Cx. pipiens pallens), Aedes(Ae. dorsalis, Ae. flavidorsalis, Ae. flavescens), and Anopheles (An. messeae). Among all the mosqutioes specimens,3 out of 150 captured An. messeae were found to carry ectoparasitic mites, with number of 2,4,27 mites separately. Morphological and molecular identification reached the same result as water mites(Hydrachnidiae, Hydracrina). COI gene sequence showed 94% similarity with the closest species Arrenurus truncatellus. Conlusions Literature review suggests water mites are host-specific parasitism of mosquito species and herein with the first record of Arrenurus sp. parasiting on An. Messeae in the most high-latitude region globally.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):83-84
Introduction:
Ectopic ACTH secretion (EAS) is a rare cause of Cushing’s
syndrome, accounting for 5–15% of cases. Pulmonary
neuroendocrine tumors are the most frequent cause.
However, primary tumor localization remains a significant
diagnostic challenge, delaying effective treatment.
Case:
A 59-year-old female with diabetes mellitus presented
with refractory hypertension and hypokalemia. Initial
laboratory findings revealed a baseline cortisol of 1,164
nmol/L and morning adrenocorticotropic hormone
(ACTH) of 19.5 pmol/L (normal <10.2 pmol/L), with an
overnight dexamethasone suppression test cortisol of
624 nmol/L. Pituitary magnetic resonance imaging (MRI)
and computed tomography (CT) scans of the thorax,
abdomen, and pelvis were initially unremarkable. A PET
scan identified mild hypermetabolism in the left adrenal
gland and gastrointestinal tract, though colonoscopy
revealed only chronic colitis. An intravenous desmopressin
stimulation test demonstrated a 181% rise in ACTH and a
35% rise in cortisol, pointing toward pituitary Cushing’s.
However, repeat pituitary MRI remained normal.
A high-dose dexamethasone suppression test showed
approximately 34% cortisol suppression (cortisol 1,128
nmol/L to 745 nmol/L), suggesting ectopic Cushing’s
syndrome. Bilateral inferior petrosal sinus sampling
demonstrated a peak central-to-peripheral ACTH ratio of
1.8 on the right and 1.6 on the left, pointing toward ectopic
Cushing’s.
Localization with DOTATATE PET-CT identified a 7 × 9 ×
8 mm nodule in the right middle lobe. A wedge resection
was performed. Histopathology confirmed a typical
carcinoid tumor with clear resection margins. Immunohistochemistry revealed tumor cells positive for CK AE1/ AE3, synaptophysin, chromogranin, and INSM-1, with
weak positivity for ACTH. The latest 8 am cortisol was 117
nmol/L and ACTH 1.74 pmol/L, confirming biochemical
cure. Hypokalemia resolved, with improvement in her
metabolic profile.
Conclusion
This case highlights the diagnostic complexities of EAS,
particularly when initial imaging is inconclusive and
biochemical tests yield conflicting results. Timely, precise
localization of the causative tumor is crucial for successful
surgical intervention and to prevent severe complications
of hypercortisolism, thereby improving patient outcomes.

RNA modifications constitute a crucial class of post-transcriptional chemical alterations that profoundly influence RNA stability and translational efficiency, thereby shaping cellular protein expression profiles. These diverse chemical marks are ubiquitously involved in key biological processes, including cell proliferation, differentiation, apoptosis, and metastatic potential, and they exert precise regulatory control over these functions. A major advance in the field is the recognition that RNA modifications do not act in isolation. Instead, they participate in complex, dynamic interactions—through synergistic enhancement, antagonism, competitive binding, and functional crosstalk—forming what is now termed the “RNA modification interactome” or “RNA modification interaction network.” The formation and functional operation of this interactome rely on a multilayered regulatory framework orchestrated by RNA-modifying enzymes—commonly referred to as “writers,” “erasers,” and “readers.” These enzymes exhibit hierarchical organization within signaling cascades, often functioning in upstream-downstream sequences and converging at critical regulatory nodes. Their integration is further mediated through shared regulatory elements or the assembly into multi-enzyme complexes. This intricate enzymatic network directly governs and shapes the interdependent relationships among various RNA modifications. This review systematically elucidates the molecular mechanisms underlying both direct and indirect interactions between RNA modifications. Building upon this foundation, we introduce novel quantitative assessment frameworks and predictive disease models designed to leverage these interaction patterns. Importantly, studies across multiple disease contexts have identified core downstream signaling axes driven by specific constellations of interacting RNA modifications. These findings not only deepen our understanding of how RNA modification crosstalk contributes to disease initiation and progression, but also highlight its translational potential. This potential is exemplified by the discovery of diagnostic biomarkers based on interaction signatures and the development of therapeutic strategies targeting pathogenic modification networks. Together, these insights provide a conceptual framework for understanding the dynamic and multidimensional regulatory roles of RNA modifications in cellular systems. In conclusion, the emerging concept of RNA modification crosstalk reveals the extraordinary complexity of post-transcriptional regulation and opens new research avenues. It offers critical insights into the central question of how RNA-modifying enzymes achieve substrate specificity—determining which nucleotides within specific RNA transcripts are selectively modified during defined developmental or pathological stages. Decoding these specificity determinants, shaped in large part by the modification interactome, is essential for fully understanding the biological and pathological significance of the epitranscriptome.
