Abstract
Background: Dengue fever continues to spread worldwide, particularly in tropical regions. Some patients with dengue fever may progress to severe dengue, which is associated with significantly higher morbidity and mortality. Despite this, no definitive treatment has been found to prevent its progression. Montelukast, a leukotriene receptor antagonist, has shown potential in reducing plasma leakage, a key factor in the pathophysiology of severe dengue. Therefore, this study aimed to evaluate the effectiveness of montelukast in reducing the risk of severe dengue. Methods: A systematic literature search was conducted on April 16, 2025, using keywords related to montelukast and dengue across four databases, which included PubMed, Taylor and Francis, Cochrane Library, and ScienceDirect. A critical appraisal was performed using the Oxford Centre for Evidence-Based Medicine framework, evaluating the validity, importance, and applicability of each study. The primary outcomes were the incidence of dengue shock syndrome and dengue with warning signs. The secondary outcomes included mortality rate and hospitalization duration. Results: This study included three studies involving a total of 1057 patients. Montelukast is associated with a reduced incidence of dengue shock syndrome and shorter duration of hospitalization. However, the effect of montelukast on dengue with warning signs and mortality rate was inconclusive. Conclusion: Montelukast shows potential as an adjuvant therapy in preventing the progression of dengue fever to severe dengue. However, further research is required before montelukast can be widely recommended for dengue fever patients in daily clinical practice and possibly integrated into dengue fever clinical guidelines.

2.Glycemic and Metabolic Outcomes of GLP-1 Receptor Agonists in Type 2 Diabetes: A Single-Centre Clinical Audit
Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):44-
Introduction:
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs)
improve glycemic control, promote weight loss, reduce
insulin requirements, and confer cardiometabolic benefits
in type 2 diabetes mellitus (T2DM). This audit evaluated
glycemic and metabolic outcomes of GLP-1 RAs in T2DM
patients at a single-centre diabetes clinic.
Methodology:
This audit included T2DM patients who initiated GLP1 RAs between January 2022 and March 2025 at Hospital
Sultan Abdul Halim. Primary outcomes were changes in
hemoglobin A1c (HbA1c), body weight, and body mass
index (BMI) at 3 and 12 months. Secondary outcomes
included percentage weight loss, changes in systolic blood
pressure (SBP), insulin total daily dose (TDD), low-density
lipoprotein (LDL) cholesterol, gastrointestinal adverse
effects, and treatment discontinuation.
Results:
Sixteen patients were included; median age was 58.5 years
(interquartile range [IQR] 47.5–65), and 56.3% were female.
Median diabetes duration was 15 years (IQR 11.5–20.3).
Median HbA1c decreased from 9.7% (IQR 8.6–10.4) at
baseline to 8.8% (IQR 7.7–9.1) at 3 months and 7.8% (IQR
7.0–8.5) at 12 months. Body weight decreased from 88.1 kg
(IQR 79.5–122.1) at baseline to 85.0 kg (IQR 75.9–113.7) at
3 months and 82.0 kg (IQR 74.8–117.3) at 12 months. BMI
decreased from 37.8 kg/m² (IQR 31.7–47.1) to 37.3 kg/m²
(IQR 30.7–45.5) at 3 months and 36.0 kg/m² (IQR 30.1–45.6)
at 12 months.
At 12 months, weight loss was 5.8% (IQR 3.0–8.0), with
56.5% achieving >5% weight reduction. In all, 93.8%
achieved >1% HbA1c reduction. Mean SBP decreased by
10 ± 20 mmHg, LDL cholesterol 0.29 mmol/L (IQR -0.77
to 0.07), and insulin TDD 8 units/day (IQR -13 to 10). No
gastrointestinal adverse effects reported. Three patients
(18.8%) discontinued treatment due to excessive weight
loss, treatment plateau, and limited drug availability.
Conclusion
From our single-centre experience, the observed improvements in glycemic and metabolic outcomes support the
benefits of GLP-1 RAs in managing T2DM.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):60-
Introduction:
Glucagon-like peptide-1 receptor agonists (GLP-1 RAs)
induce clinically meaningful weight reduction in patients
with type 2 diabetes mellitus (T2DM), but real-world data
in Southeast Asian populations are limited. This study
evaluated the effectiveness of GLP-1 RAs in achieving
clinically significant weight loss in Malaysian patients with
obesity and T2DM.
Methodology:
A retrospective cohort study was conducted among adults
with T2DM and obesity attending the Endocrinology Clinic
at Hospital Sultan Abdul Aziz Shah between January
2023 and December 2024. Patients receiving GLP-1 RAs
(semaglutide or liraglutide) were compared with those on
standard care. Anthropometric outcomes were assessed
over 6–12 months, with weight loss thresholds of ≥3, ≥5,
and ≥10%. Between-group comparisons used Fisher’s exact
test, and odds ratios (OR) were calculated.
Results:
Eighty-five patients were included (GLP-1, n = 47; control,
n = 38). The GLP-1 group achieved significantly higher rates
of any weight loss (70.0% vs 41.2%; OR = 3.33, p = 0.019)
and ≥3% weight loss (42.5% vs 14.7%; OR = 4.29, p = 0.011).
Number needed to treat was 3–4 patients. Proportions
achieving ≥5 and ≥10% weight loss were higher in the
GLP-1 group but did not reach statistical significance.
Conclusion
GLP-1 RA therapy significantly improves the likelihood
of clinically meaningful weight loss in Malaysian patients
with obesity and T2DM. These findings support the
integration of GLP-1 RAs into routine obesity management
strategies in Southeast Asia.

Journal of the ASEAN Federation of Endocrine Societies 2026;41(S1):61-62
Introduction:
While Glucagon-like peptide-1 receptor agonists (GLP-1
RAs) are effective for weight reduction in type 2 diabetes
mellitus (T2DM), interindividual variability exists.
Lifestyle factors, particularly baseline physical activity,
may modify weight loss outcomes. This study examined
whether baseline activity influences GLP-1 RA efficacy in
Malaysian patients.
Methodology:
A retrospective cohort of adults with obesity and T2DM
receiving GLP-1 RAs (semaglutide or liraglutide) from
January 2023 to December 2024 was analyzed. Baseline
physical activity was classified as active or inactive.
Primary outcomes were achievement of ≥3 and ≥5% weight
loss over 6–12 months. Associations were assessed using
Fisher’s exact test and logistic regression.
Results:
Among GLP-1-treated patients, those reporting baseline
physical activity were more likely to achieve ≥3% weight loss
and demonstrated trends toward higher, ≥5%, weight loss.
Logistic regression suggested baseline activity increased
the odds of clinically meaningful weight reduction, though
statistical significance was limited by sample size.
Conclusion
Baseline physical activity may enhance GLP-1 receptor
agonist-mediated weight loss in obese patients with T2DM.
Integrating lifestyle interventions with pharmacotherapy
may optimize treatment outcomes. Larger prospective
studies are warranted to confirm these findings.

5.Therapeutic components of acupuncture stimulation based on characteristics of sensory nerve and nervous signaling pathway.
Journal of Integrative Medicine 2025;23(2):106-112
Acupuncture, a therapeutic practice rooted in traditional Chinese medicine and integrated with modern neuroscience, achieves its effects by stimulating sensory nerves at specific anatomical points known as acupoints. This review systematically explores the therapeutic components of acupuncture, emphasizing the interplay between sensory nerve characteristics and neural signaling pathways. Key factors such as acupoint location, needling depth, stimulation intensity, retention time, and the induction of sensations (e.g., Deqi) are analyzed for their roles in neural activation and clinical outcomes. The review highlights how variations in spinal segment targeting, tissue-specific receptor activation, and stimulation modalities (e.g., manual acupuncture, electroacupuncture, moxibustion) influence therapeutic effects. Emerging evidence underscores the significance of ion channels, dermatomes, myotomes, and gene-specific pathways in mediating systemic effects. Additionally, the differential roles of mechanical, thermal and nociceptive stimuli and the temporal dynamics of sensory and immune responses are addressed. While insights from animal models have advanced our understanding, their translation to clinical practice requires further investigation. This comprehensive review identifies critical parameters for optimizing acupuncture therapy, advocating for individualized treatment strategies informed by neuroanatomical and neurophysiological principles, ultimately enhancing its precision and efficacy in modern medicine.

OBJECTIVE:
The occurrence and development of atrial fibrillation (AF) are influenced by the autonomic nervous system and inflammation. Acupuncture is an effective treatment for AF. This study explored the protective effects of acupuncture in a rat model of paroxysmal AF and investigated its mechanisms.
METHODS:
Male Sprague-Dawley rats (n = 130) were randomly divided into blank control (Con), sham operation (Sham), AF, and acupuncture treatment (Acu) groups. A paroxysmal AF model was established by rapid atrial pacing through the jugular vein. Rats in the Acu group were immobilized to receive acupuncture treatment at Neiguan acupoint (PC6) for 20 min daily for seven days. The other groups were immobilized for the same duration over the treatment period but did not receive acupuncture. The AF induction rate, AF duration, cardiac electrophysiological parameters, and heart rate variability were evaluated by monitoring surface electrocardiogram and vagus nerve discharge signals. After the intervention, the rats were euthanized, and atrial morphology was assessed using haematoxylin and eosin staining. The expression of macrophage F4/80 antigen (F4/80) and cluster of differentiation (CD) 86 in atrial myocardial tissue was detected using immunohistochemistry, immunofluorescence and flow cytometry. The expression levels or contents of interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), α7 nicotinic acetylcholine receptor (α7nAChR), phosphorylated Janus kinase 2 (p-JAK2), and phosphorylated signal transducer and activator of transcription 3 (p-STAT3) in atrial myocardial tissue were detected using Western blotting, reverse transcription-quantitative polymerase chain reaction, or enzyme-linked immunosorbent assay. The role of α7nAChR in acupuncture treatment was verified by intraperitoneal injection of the α7nAChR antagonist methyllycaconitine (MLA).
RESULTS:
Compared with the AF group, acupuncture significantly reduced AF duration and induction rate, improved cardiac electrophysiology by enhancing vagus nerve activity and regulating autonomic balance. It also decreased the pro-inflammatory M1 macrophage proportion, alleviating myocardial injury and infiltration. MLA weakened acupuncture's electrophysiological improvement and anti-inflammatory effect. Results suggest that acupuncture triggers the α7nAChR-JAK2/STAT3 pathway and exerts cardioprotection via neuroimmune regulation.
CONCLUSION
Acupuncture significantly reduced the AF induction rate, shortened AF duration, improved cardiac electrophysiological parameters, enhanced vagus nerve activity, and decreased the expression of pro-inflammatory M1 macrophages and inflammatory factors in rats with paroxysmal AF. Its positive effects are related to the activation of the α7nAChR-mediated JAK2/STAT3 signalling pathway, indicating that the interaction between cardiac vagus nerve and macrophages may be a potential target for acupuncture in the prevention and treatment of AF.

OBJECTIVE:
Glucocorticoid-induced osteoporosis (GIOP) is a common complication of prolonged glucocorticoid therapy. Chlorogenic acid (CGA), a polyphenol with antioxidant properties that is extracted from traditional Chinese medicines such as Eucommiae Cortex, has potential anti-osteoporotic activity. This study aimed to investigate the possible effects of CGA on GIOP in mice and murine long bone osteocyte Y4 (MLO-Y4) cells and explore the underlying molecular mechanisms.
METHODS:
The protective effects of CGA were initially evaluated in the GIOP mouse model induced by dexamethasone (Dex). The micro-computed tomography, hematoxylin-eosin staining, silver nitrate staining, and serum detection were used to assess the efficacy of CGA for improving bone formation in vivo. Then, network pharmacology analysis was used to predict the potential targets and molecular mechanisms underlying the therapeutic efficacy of CGA against GIOP. After that, 2',7'-dichlorofluorescein diacetate staining, flow cytometry, real-time quantitative reverse transcription polymerase chain reaction, and Western blotting were used to verify the mechanisms of CGA against GIOP in vitro.
RESULTS:
Animal experiments showed that CGA treatment effectively attenuated Dex-induced decreases in bone mass and strength and improved disrupted osteocyte morphology in mice. The protein-protein interaction analysis highlighted erb-b2 receptor tyrosine kinase (ERBB2), which is also known as human epidermal growth factor receptor 2 (HER2), caspase-3, kinase insert domain receptor, matrix metallopeptidase 9, matrix metallopeptidase 2, proto-oncogene tyrosine-protein kinase Src, and epidermal growth factor receptor as core targets. The Kyoto Encyclopedia of Genes and Genomes analysis revealed several significantly enriched pathways (P < 0.05), including the ERBB, phosphoinositide 3 kinase-AKT serine/threonine kinase 1 (AKT), and mechanistic target of rapamycin kinase (mTOR) pathways. Cellular experiments verified that CGA enhanced bone formation and promoted autophagy while inhibiting apoptosis in MLO-Y4 cells exposed to Dex, which was associated with the upregulated expression of HER2 and activation of the HER2/AKT/mTOR signaling pathway.
CONCLUSION
CGA exerted anti-osteoporotic effects against GIOP, partially through targeting osteocytes and modulating the HER2/AKT/mTOR signaling pathway.

Tianxiangdan (TXD), a traditional Chinese herbal remedy, demonstrates efficacy in mitigating myocardial ischemia-reperfusion (I/R)-induced damage. This study employed network pharmacology to evaluate the therapeutic targets and mechanisms of TXD in treating I/R. High-performance liquid chromatography-mass spectrometry (HPLC-MS) identified 86 compounds in TXD. Network pharmacological analysis predicted potential target genes and their modes of action. Cardiac function, ischaemic ST changes, lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD) activity, myocardial fiber, and infarct size were assessed using in vivo and in vitro I/R injury models. Estrogen receptor alpha (ERα) protein expression and estradiol (E2) levels were measured to confirm TXD's impact on estrogen levels and ERα expression. To examine if TXD reduces I/R injury through ERα, an AZD group (300 nmol·L-1 AZD9496 and 15% TXD serum) was compared to a TXD group (15% TXD serum). The study hypothesized that TXD upregulates the ERα-mediated iron metamorphosis pathway. I/R injury-induced ferroptosis was identified using a Fer-1 group (1.0 μmol·L-1 Fer-1 and 15% TXD serum) to elucidate the potential association between ferroptosis and ERα proteins. A DCFH-DA probe detected reactive oxygen species (ROS) and Fe2+, while Western blotting assessed target protein expression. Both in vitro and in vivo experiments demonstrated that TXD attenuated I/R injury by reducing elevated ST-segment levels, improving cardiac injury biomarkers (LDH, MDA, and SOD), alleviating pathological features, and preventing I/R-induced loss of cell viability in vitro. The effects and mechanisms of TXD on I/R injury-associated ferroptosis were investigated using I/R-induced H9c2 cells. The TXD group showed significantly decreased ROS and Fe2+ levels, while the AZ group (treated with AZD9496) exhibited increased levels. The TXD group demonstrated enhanced expression of ERα and glutathione peroxidase 4 (GPX4), with reduced levels of P53 protein and ferritin-heavy polypeptide 1 (FTH1). The AZ group exhibited contrasting effects on these expression levels. The literature indicated a novel connection between ERα and ferroptosis. TXD activates the ERα signaling pathway, promoting protection against I/R-induced myocardial cell ferroptosis. This study provides evidence supporting TXD use for myocardial ischemia treatment, particularly in older female patients who may benefit from its therapeutic outcomes.

Eight previously undescribed lanostane triterpenoids, including five nortriterpenoids with 26 carbons, ganothenoids A-E (1-5), and three lanostanoids, ganothenoids F-H (6-8), along with 24 known ones (9-32), were isolated from the fruiting bodies of Ganodrma theaecolum. The structures of the novel compounds were elucidated using comprehensive spectroscopic methods, including electronic circular dichroism (ECD) and nuclear magnetic resonance (NMR) calculations. Compounds 1-32 were assessed for their neuroprotective effects against H2O2-induced damage in human neuroblastoma SH-SY5Y cells, as well as their inhibitory activities against protein tyrosine phosphatase 1B (PTP1B) and α-glucosidase. Compound 4 demonstrated the most potent neuroprotective activity against H2O2-induced oxidative stress by suppressing G0/G1 phase cell cycle arrest, reducing reactive oxygen species (ROS) levels, and inhibiting cell apoptosis through modulation of B-cell lymphoma 2 protein (Bcl-2) and Bcl-2 associated X-protein (Bax) protein expression. Compounds 26, 12, and 28 exhibited PTP1B inhibitory activities with IC50 values ranging from 13.92 to 56.94 μmol·L-1, while compound 12 alone displayed significant inhibitory effects on α-glucosidase with an IC50 value of 43.56 μmol·L-1. Additionally, enzyme kinetic analyses and molecular docking simulations were conducted for compounds 26 and 12 with PTP1B and α-glucosidase, respectively.

Lingguizhugan Decoction (LGZG) demonstrates significant efficacy in treating various cardiovascular diseases clinically, yet its precise mechanism of action remains elusive. This study aimed to elucidate the potential mechanisms and effects of LGZG on isoproterenol (ISO) continuous stimulation-induced chronic heart failure (CHF) in mice, providing direct experimental evidence for further clinical applications. In vivo, continuous ISO infusion was administered to mice, and ventricular myocytes were utilized to explore LGZG?s potential mechanism of action on the ?1-adrenergic receptor (?1-AR)/Gs/G protein-coupled receptor kinases (GRKs)/?-arrestin signaling deflection system in the heart. The findings reveal that LGZG significantly reduced the messenger ribonucleic acid (mRNA) expression of hypertrophy-related biomarkers [atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP)] and improved cardiac remodeling and left ventricular diastolic function in mice with ISO-induced CHF. Furthermore, LGZG inhibited the overactivation of Gs/cyclic adenosine monophosphate (cAMP)/protein kinase A (PKA) signaling and downregulated the downstream transcriptional activity of cAMP-response element binding protein (CREB) and the expression of the coactivator CBP/P300. Notably, LGZG downregulated the expression of ?-arrestin1 and GRK 2/3/5 while upregulating the expression of ?1-AR and ?-arrestin2. These results suggest that LGZG inhibits Gs/cAMP/PKA signaling and ?-arrestin/GRK-mediated desensitization and internalization of ?1-AR, potentially exerting cardioprotective effects through the synergistic regulation of the ?1-AR/Gs/GRKs/?-arrestin signaling deflection system via multiple pathways.
