ObjectiveTo address the challenges of unstructured classical Chinese expressions, nested entity relationships, and limited annotated data in famous traditional Chinese medicine(TCM) case records, this study proposes a joint relation extraction framework that integrates data augmentation and entity mapping, aiming to support the construction of TCM diagnostic knowledge graphs and clinical pattern mining. MethodsWe developed an annotation structure for entities and their relationships in TCM case texts and applied a data augmentation strategy by incorporating multiple ancient texts to expand the relation extraction dataset. A cascade binary tagging framework for relation triple extraction(CasRel) model for TCM semantics was designed, integrating a pre-trained bidirectional encoder representations from transformers(BERT) layer for classical TCM texts to enhance semantic representation, and using a head entity-relation-tail entity mapping mechanism to address entity nesting and relation overlapping issues. ResultsExperimental results showed that the CasRel model, combining data augmentation and entity mapping, outperformed the pipeline-based Bert-Radical-Lexicon(BRL)-bidirectional long short-term memory(BiLSTM)-Attention model. The overall precision, recall, and F1-score across 12 relation types reached 65.73%, 64.03%, and 64.87%, which represent improvements of 14.26%, 7.98%, and 11.21% compared to the BRL-BiLSTM-Attention model, respectively. Notably, the F1-score for tongue syndrome relations increased by 22.68%(69.32%), and the prescription-syndrome relations performed the best with the F1-score of 70.10%. ConclusionThe proposed framework significantly improves the semantic representation and complex dependencies in TCM texts, offering a reusable technical framework for structured mining of TCM case records. The constructed knowledge graph can support clinical syndrome differentiation, prescription optimization, and drug compatibility, providing a methodological reference for TCM artificial intelligence research.

OBJECTIVE To establish a method for simultaneously determining three anti-tuberculosis drugs in the plasma of patients with spinal tuberculosis and apply it in clinical practice. METHODS LC-MS/MS method was established for the quantitative determination of the concentrations of isoniazid, rifampicin and pyrazinamide in the plasma of patients with spinal tuberculosis, using diphenhydramine as the internal standard. The determination was carried out using Chemalink CM-C18T column, with mobile phase consisting of 0.1% formic acid-methanol solution (gradient elution), at the flow rate of 0.4 mL/min and an injection volume of 2 μL. Multiple reaction monitoring was conducted using an electrospray ionization source in positive ion mode. The ion pairs used for quantitative analysis were m/z 138.0→121.0( for isoniazid), m/z 823.3→791.3( for rifampicin), m/z 124.1→ 79.0 (for pyrazinamide), and m/z 256.0→167.0 (for diphenhydramine). Fifty-three patients diagnosed with spinal tuberculosis in Qinghai Provincial People’s Hospital from January 2023 to June 2025 were selected, and the plasma concentrations of isoniazid, rifampicin and pyrazinamide in these patients were measured using the above method. RESULTS The linear ranges for isoniazid, rifampicin and pyrazinamide were 0.5-16, 2-64, and 2.5-80 μg/mL, respectively (r≥0.998 7). The accuracy ranged from 90.20% to 108.64% (n=5). RSDs for intra-day precision were all less than 6.63% (n=5), while those for inter-day precision were all less than 8.42% (n=3). The matrix effects ranged from 88.60% to 115.41% (n=5). The relative deviations in the stability tests were all within the ±15% range, and the carry-over effect did not interfere with the determination. The results of clinical application showed that the mean plasma drug concentrations of isoniazid, rifampicin and pyrazinamide in patients with spinal tuberculosis were (3.62±2.80), (8.55±4.57), and (20.12±6.56) μg/mL, respectively. The incidences of plasma drug concentrations falling below the effective peak concentrations were 49.06%, 58.49% and 60.38%, respectively. CONCLUSIONS The method established in this study is rapid, accurate, and demonstrates good stability, making it suitable for clinical monitoring of the plasma concentrations of isoniazid, rifampicin and pyrazinamide in patients with spinal tuberculosis.

Introduction: Staphylococcus aureus is the leading biofilmforming microorganisms in orthopaedic implant infections.
The biofilms formed are difficult to eradicate and resistance
to antibiotics. This current study aims to determine the
effectiveness of povidone-iodine; an antiseptic solution in
eradicating S. aureus biofilm on stainless steel alloy. In
addition to the usual Colony-Forming Unit (CFU) used for
verification, Scanning Electron Microscope (SEM) is used to
validate the formation and eradication of the biofilms.
Materials and methods: This is an in vitro study where the
biofilm is formed by inoculating clinically isolated S. aureus,
incubated for 24 hours onto stainless steel alloy 316L
implants. The implants are then irrigated using povidoneiodine solution with varying concentrations (5 and 10%) and
durations (30, 60, and 180 seconds). The anti-biofilm effect
was evaluated using plating and SEM methods to confirm its
effectiveness. The process is repeated after 24 hours of postirrigation reincubation to detect any rebound growth.
Results: No biofilm seen after irrigation with povidoneiodine at 5% and 10% concentrations at 30, 60 and 180
seconds, respectively, in both CFU count and SEM. This
result is replicated after 24 hours of reincubation, in
assessing for rebound growth.
Conclusion: Our study supports that a minimum of 5%
povidone-iodine with a minimum irrigation time of 30
seconds are effective at eliminating S. aureus biofilm on
stainless steel alloy implants. Both CFU count and SEM
yield similar value in validating the presence of biofilm.
Additionally, SEM allows visualisation of the morphology of
the biofilm.

Objective: To analyze the causes of abnormal blood agglutination caused by high-titer cold antibodies in blood donors from a serological perspective. Methods: The donor's blood type was identified using the tube method. Direct antiglobulin test (DAT), indirect antiglobulin test (IAT), and antibody titer detection were performed on the samples. Results: The blood type of the donor was type B, and the DAT was negative. No complement components were detected on the surface of the donor's red blood cells. The supernatant of the suspended red blood cells was clear without abnormal coloration, and the agglutinated clumps were intact and difficult to dissociate. The antibody was identified as an IgM-type anti-IH cold agglutinin. At 4℃, this antibody reacted with autologous red blood cells, adult group B red blood cells, adult group O red blood cells, cord blood group B red blood cells and cord blood group O red blood cells, with a stronger reaction intensity observed with group O cells than with B cells. The titers were 512, 128, 256, 32 and 128, respectively. Conclusion: High-titer anti-IH can cause abnormal agglutination of blood at low temperatures. During blood distribution and clinical use, the appearance of blood products shall be strictly inspected to prevent the release of non-conforming blood products.

Purpose: Adjuvant radiotherapy (RT), while effective in reducing cancer recurrence and improving survival
rates, often comes with radiation toxicity that can adversely affect the patient’s quality of life (QoL). Evaluating
toxicity after RT is crucial because it helps to identify and manage adverse effects that can significantly impact
a patient’s QoL. By monitoring toxicity, we can adjust treatment plans to mitigate these effects, improve patient
comfort, and ensure a better overall outcome. Therefore this study aimed to evaluate and compare QoL following
3D-conformal hypofractionated RT in breast cancer patients. Methods: We included twenty-one Malaysian women
with unilateral breast cancer treated with lumpectomy (n=15) or mastectomy (n=6) followed by 3D-conformal
hypofractionated RT. QoL was evaluated using the EORTC QLQ-BR45 questionnaire before, during, and
after RT. Results: During RT, there was a significant increase in the mean score of the breast symptoms scale
compared to baseline (p=0.002), with the most common symptoms being skin problems, followed by swelling and
oversensitivity. However, these symptoms were generally mild for most patients. The other quality of life scales
remained stable during RT. Post-RT, most QoL scales showed improvements compared to both baseline and
during RT, with significant enhancements in the mean breast symptoms score and breast satisfaction score (all
p<0.05). Conclusion: Radiotherapy negatively impacted the QoL of our breast cancer patients, specifically on the
breast symptoms scale. However, these symptoms improved after 4 months, resulting in high breast satisfaction
and indicating a near-excellent cosmetic outcome. Future studies with larger cohorts are essential to validate
these findings, as the small sample size (n=21 at baseline; n=13 post-RT) may have limited the detection of more
subtle changes

Despite publishing and securing research grants being obligatory in research universities, the literature on the
factors influencing academic productivity is relatively scarce. Thus, in this study, we aimed to determine the
personal and behavioural-related factors that influence the culture of publishing and securing research grants
among academicians with lower research-related performance. This cross-sectional study was conducted among 49
academic staff members of Universiti Kebangsaan Malaysia (UKM). A self-administered questionnaire consisting
of personal, attitude and behavioural (barriers, perceived stress scale, work extrinsic and intrinsic motivation
scale, psychological well-being scale, and basic needs satisfaction scale) questions were distributed during a
workshop and online. Simple linear regression (SLR) analyses were performed for each variable, followed by
multiple linear regression (MLR) to identify the associated factors of research output. After adjusting for covariates,
having a doctoral degree (β=0.396, 95% CI=0.221-2.146, p<0.05) and integrated regulation (β=0.574, 95%
CI=0.036-3.612, p<0.05) were found to be associated with research grant acquisition (R2=0.273). Moreover,
increasing age (β=0.426, 95% CI=0.088-0.397, p<0.05), living alone (β=0.331, 95% CI=0.944-6.626, p<0.05),
having a doctoral degree (β=0.248, 95% CI=0.174-6.747, p<0.05), environmental mastery (β=0.318, 95%
CI=0.013-0.347, p<0.05), self-acceptance (β=0.284, 95% CI=0.010-0.242, p<0.05), satisfaction incompetence
(β=0.273, 95% CI=0.001-0.200, p<0.05) and relatedness (β=0.280, 95% CI=0.001-0.116, p<0.05) were found to
be the factors that influence the publications produced among participants (R2
=0.423). The findings of this study
could be used by management to formulate effective strategies to increase the productivity of academics in their
research-related performance.

Pulmonary rehabilitation (PR) has become an indispensable component of the modern care continuum for lung cancer. Substantial evidence confirms its definitive value in improving perioperative outcomes, mitigating treatment-related side effects, and enhancing quality of life in patients with advanced disease. However, a significant "implementation gap" exists between its proven clinical benefits and widespread application, primarily characterized by the lack of standardized protocols, uncertainty in optimal timing, and low patient adherence. Bridging this gap requires a dual-driven approach: harnessing technological innovations such as telerehabilitation, wearable devices, and artificial intelligence to enhance accessibility and personalization, alongside optimizing care models through multidisciplinary team collaboration. This review systematically analyzes the evidence, implementation barriers, and innovative pathways for PR in lung cancer care, aiming to catalyze its transition from an ancillary option to a core standard of care, and envisions a new paradigm of personalized PR that is patient-centered, data-driven, and technologically integrated.

INTRODUCTION: In the clinical setting, erectile dysfunction (ED) is a significant issue
that should not be neglected, as it can adversely impact the quality of life of patients
and their partners, especially among overweight and obese populations. This study
aims to determine the prevalence of ED and its associated factors among non-diabetic,
overweight, and obese patients who attend a government health clinic in Kuantan,
Pahang, Malaysia. MATERIALS AND METHODS: A six-month cross-sectional study
was conducted from February 2024 to August 2024 at twelve health clinics in
Kuantan, Pahang. The selected respondents were married men over 18 years old, and
those with diabetes mellitus, cardiovascular disease, psychiatric illness, or illiteracy were
excluded. Data were collected using the validated Malay version of the International
Index of Erectile Function (IIEF-5). ED was defined as an IIEF-5 score of less than
22. Descriptive analysis and simple and multiple logistic regression were performed
using SPSS. RESULTS: All 221 eligible patients in the study responded (100% response
rate). The prevalence of ED was 66.1% (n=146). Multiple logistic regression
showed that ED was significantly associated with dyslipidemia [AOR (95% CI): 2.42
(1.06–5.52); p-value=0.036], anxiety [AOR (95% CI): 3.99 (1.44–11.01);
p-value=0.008] and older age [AOR (95% CI): 1.07 (1.02–1.12); p-value=0.009].
CONCLUSION: The study revealed a high prevalence of ED among non-diabetic
overweight and obese patients, potentially linked to increasing age, dyslipidemia, and
anxiety. Increasing awareness among the public and healthcare providers could
improve detection rates in primary care.

INTRODUCTION: Glaucoma is a leading cause of permanent blindness, often going
undetected in its early, asymptomatic stages, especially in older age groups. In
Malaysia, glaucoma is a growing public health issue due to an increase in the ageing
population. While screening is essential for early glaucoma detection, the most
suitable strategy for Malaysia's healthcare system remains unclear. This study
explored the perspectives of eye healthcare professionals on the most suitable
glaucoma screening strategies for Malaysia. MATERIAL AND METHODS: This
qualitative study used semi-structured interviews with 19 eye health professionals
(ophthalmologists, optometrists, nurses, ophthalmic technicians, and assistant
medical officers) practicing in the Klang Valley. The interviews were conducted
face-to-face in their workplace or via a video conferencing platform. All interviews
were recorded, transcribed, and analysed using thematic analysis. RESULTS: Six
major themes were identified: types of glaucoma screening programmes, accessible
screening locations, target screening population, instruments and use of digital
technology, trained personnel, and referral criteria. Opportunistic case finding and
population-based programmes were identified as the glaucoma screening
programmes in which trained personnel conducted screening at accessible
locations. Glaucoma screening for high-risk individuals was recommended,
focusing on visual acuity testing, tonometry, anterior chamber angle assessment,
funduscopy, perimetry, and retinal nerve fibre assessment. A lack of clear referral
criteria due to low awareness and poor implementation of existing guidelines was
observed. CONCLUSION: Further investigations are required to identify the best
combination of components for glaucoma screening. This will enable policymakers
to develop an effective glaucoma screening programme in Malaysia.

OBJECTIVE To investigate the protective effects and potential mechanism of alisol B 23-acetate on acute alcoholic liver injury in mice. METHODS Fifty male Kunming mice were divided into the blank group, model group, and alisol B 23-acetate low-, medium- and high-dose groups (10, 20, 40 mg/kg), with 10 mice in each group. Each group was given relevant drug solution or normal saline intragastrically, once a day, for 2 consecutive weeks. On the 15th day, mice in the blank group were given normal saline intragastrically, while the other four groups were given 12 mL/kg white wine intragastrically, twice at six-hour intervals, to establish an acute alcoholic liver injury model. On the 16th day of the experiment, the liver indexes of mice in each group were calculated; the serum levels of alanine transaminase (ALT), aspartate transaminase (AST), total cholesterol (TC), triglycerides (TG), malondialdehyde (MDA) and glutathione (GSH) were also determined. The histopathological morphology of their liver tissues was observed and scored. The protein expressions of cytochrome P450 2E1 (CYP2E1), Kelch-like ECH-associated protein 1 (Keap1), nuclear factor erythroid 2-related factor 2 (Nrf2) and NAD(P)H: quinone oxidoreductase 1 (NQO1) were measured in liver tissue. RESULTS Compared with model group, mice in each dosage group of alisol B 23-acetate showed varying degrees of recovery in body weight, along with improvements in pathological changes in liver tissues such as inflammatory cell infiltration and fatty vacu oles. Their liver indexes, histopathological scores of liver tissue, serum levels of ALT, AST, TC, TG and MDA, as well as the protein expressions of CYP2E1 and Keap1 in liver tissue, were all significantly decreased ( P <0.05 or P <0.01). The serum GSH levels and the protein expressions of Nrf2 (except for the alisol B 23-acetate low-dose group) and NQO1 in liver tissue were significantly increased ( P <0.05 or P <0.01), and the changes in the above quantitative indicators showed a dose-dependent pattern. CONCLUSIONS Alisol B 23-acetate can ameliorate acute alcoholic liver injury in mice, and its mechanism may be related to improving antioxidant capacity by regulating the Keap1/Nrf2/NQO1 signaling pathway while simultaneously improving liver lipid metabolism-related indexes.
