		                        			Objective To explore the utility of comprehensive geriatric assessment (CGA) in screening risk factors for osteosarcopenia (OS) among older adults (≥80 years old) and to evaluate the therapeutic efficacy of CGA-guided integrated interventions for OS. Methods A total of 420 patients aged ≥80 years, recruited from the Department of Geriatrics, General Practice of The Affiliated Jiangyin Hospital of Nantong University, and community health centers from January 2022 to October 2024, were enrolled. Participants were classified into OS (n=139) and non-OS (n=281) groups based on diagnostic criteria. CGA was utilized to compare differences in general characteristics, laboratory indicators, comorbidities between groups. Binary logistic regression analysis identified independent risk and protective factors. Subsequently, 40 OS patients were randomly assigned to an intervention group (n=20) receiving integrated interventions including nutritional support, exercise training, and psychological management or a control group (n=20, receiving routine care). Appendicular skeletal muscle mass index (ASMI), grip strength, gait speed, and bone mineral density (BMD) T-score were compared between groups after 3 months. Results The prevalence of OS in this cohort was 33.1%. Compared to the non-OS group, the OS group exhibited significant differences in age, body mass index (BMI), smoking history, comorbidity index, concomitant medication, cognitive impairment, visual and hearing impairment, sleep disorders, depression, marital status, social participation, activities of daily living, nutritional risk, total cholesterol, uric acid, and constipation (P<0.05). Logistic regression analysis identified age and comorbidity index as significant risk factors for OS, while BMI, married status, total cholesterol, and activities of daily living (assisted and independent) served as protective factors. The intervention group demonstrated significant improvements in grip strength, gait speed, BMD T-score, and male ASMI compared to controls (P<0.05). Conclusions CGA demonstrates clinical utility in systematically identifying risk factors for OS in the old population. Multimodal interventions guided by CGA effectively improve musculoskeletal function in elderly OS patients.

		                        			Introduction: Numerous novel systemic treatments have emerged for patients with primary metastatic prostate cancer (mPC), addressing both hormone-sensitive (mHSPC) and castration-resistant prostate cancer (mCRPC). However,
limited understanding exists in integrating these therapies into clinical practice. This study provides an overview of
mPC, presenting baseline disease characteristics, treatment profiles, and outcomes of mPC specifically in Sarawak.
Materials and methods: Our study focused on registered male patients diagnosed with metastatic prostate cancer at
Sarawak General Hospital between 2016 and 2023, aged over 18. Surveys were carried out during routine clinical
practice, covering patient demographics, clinical parameters, primary treatments, follow-up, and outcomes. The
study described treatment patterns following diagnosis. Results: Demographic and tumor profiles of 212 patients
with metastatic prostate cancer in Sarawak General Hospital from 2016- 2023 were retrospectively analyzed. Patients with mPC was notably prevalent among individuals of Chinese ethnicity, accounting for 43.4% of cases, with
over 50% of patients presenting with high-volume disease irrespective of ethnicity. The primary treatment modality
for the majority of mPC patients was androgen deprivation therapy (ADT) alone. Among the cohort, 19.3% (n=41)
experienced disease progression to metastatic castration-resistant prostate cancer (mCRPC) since 2016. Novel hormonal therapy (NHT) emerged as the predominant first-line treatment for mCRPC, administered to 53.7% of patients.
Conclusion: The majority of prostate cancer patients in Sarawak are diagnosed in the metastatic stage and were of
high volume at diagnosis. Aggressive treatment was initiated early in an attempt to improve treatment outcomes and
overall survival.

		                        			Alzheimer’s disease (AD), a progressive neurodegenerative disorder and the leading cause of dementia in the elderly, is characterized by severe cognitive decline, loss of daily living abilities, and neuropsychiatric symptoms. This condition imposes a substantial burden on patients, families, and society. Despite extensive research efforts, the complex pathogenesis of AD, particularly the early mechanisms underlying cognitive dysfunction, remains incompletely understood, posing significant challenges for timely diagnosis and effective therapeutic intervention. Among the various cellular components implicated in AD, GABAergic interneurons have emerged as critical players in the pathological cascade, playing a pivotal role in maintaining neural network integrity and function in key brain regions affected by the disease. GABAergic interneurons represent a heterogeneous population of inhibitory neurons essential for sustaining neural network homeostasis. They achieve this by precisely modulating rhythmic oscillatory activity (e.g., theta and gamma oscillations), which are crucial for cognitive processes such as learning and memory. These interneurons synthesize and release the inhibitory neurotransmitter GABA, exerting potent control over excitatory pyramidal neurons through intricate local circuits. Their primary mechanism involves synaptic inhibition, thereby modulating the excitability and synchrony of neural populations. Emerging evidence highlights the significant involvement of GABAergic interneuron dysfunction in AD pathogenesis. Contrary to earlier assumptions of their resistance to the disease, specific subtypes exhibit vulnerability or altered function early in the disease process. Critically, this impairment is not merely a consequence but appears to be a key driver of network hyperexcitability, a hallmark feature of AD models and potentially a core mechanism underlying cognitive deficits. For instance, parvalbumin-positive (PV+) interneurons display biphasic alterations in activity. Both suppressing early hyperactivity or enhancing late activity can rescue cognitive deficits, underscoring their causal role. Somatostatin-positive (SST+) neurons are highly sensitive to amyloid β-protein (Aβ) dysfunction. Their functional impairment drives AD progression via a dual pathway: compensatory hyperexcitability promotes Aβ generation, while released SST-14 forms toxic oligomers with Aβ, collectively accelerating neuronal loss and amyloid deposition, forming a vicious cycle. Vasoactive intestinal peptide-positive (VIP+) neurons, although potentially spared in number early in the disease, exhibit altered firing properties (e.g., broader spikes, lower frequency), contributing to network dysfunction (e.g., in CA1). Furthermore, VIP release induced by 40 Hz sensory stimulation (GENUS) enhances glymphatic clearance of Aβ, demonstrating a direct link between VIP neuron function and modulation of amyloid pathology. Given their central role in network stability and their demonstrable dysfunction in AD, GABAergic interneurons represent promising therapeutic targets. Current research primarily explores three approaches: increasing interneuron numbers (e.g., improving cortical PV+ interneuron counts and behavior in APP/PS1 mice with the antidepressant citalopram; transplanting stem cells differentiated into functional GABAergic neurons to enhance cognition), enhancing neuronal activity (e.g., using low-dose levetiracetam or targeted activation of specific molecules to boost PV+ interneuron excitability, restoring neural network γ‑oscillations and memory; non-invasive neuromodulation techniques like 40 Hz repetitive transcranial magnetic stimulation (rTMS), GENUS, and minimally invasive electroacupuncture to improve inhibitory regulation, promote memory, and reduce Aβ), and direct GABA system intervention (clinical and animal studies reveal reduced GABA levels in AD-affected brain regions; early GABA supplementation improves cognition in APP/PS1 mice, suggesting a therapeutic time window). Collectively, these findings establish GABAergic interneuron intervention as a foundational rationale and distinct pathway for AD therapy. In conclusion, GABAergic interneurons, particularly the PV+, SST+, and VIP+ subtypes, play critical and subtype-specific roles in the initiation and progression of AD pathology. Their dysfunction significantly contributes to network hyperexcitability, oscillatory deficits, and cognitive decline. Understanding the heterogeneity in their vulnerability and response mechanisms provides crucial insights into AD pathogenesis. Targeting these interneurons through pharmacological, neuromodulatory, or cellular approaches offers promising avenues for developing novel, potentially disease-modifying therapies.

		                        			ObjectiveTo develop a nomogram-based risk prediction model for chronic obstructive pulmonary disease (COPD) incidence among the community-dwelling population aged 40 years old and above, so as to provide targeted references for the screening and prevention of COPD. MethodsBased on a natural population cohort in suburban Shanghai, a total of 3 381 randomly selected participants aged ≥40 years underwent pulmonary function tests between July and October 2021. Cox stepwise regression analysis was used to develop overall and gender-specific risk prediction models, along with the construction of corresponding risk nomograms. Model predictive performance was evaluated using the C-indice, area under the curve (AUC) values, and Brier score. Stability was assessed through 10-fold cross-validation and sensitivity analysis. ResultsA total of 3 019 participants were included, with a median follow-up duration of 4.6 years. The COPD incidence density was 17.22 per 1 000 person-years, significantly higher in males (32.04/1 000 person-years) than that in females (7.38/1 000 person-years) (P<0.001). The overall risk prediction model included the variables such as gender, age, education level, BMI, smoking, passive smoking, and respiratory comorbidities. The male-specific model incorporated the variables such as age, BMI, respiratory comorbidities, and smoking, while the female-specific model included age, marital status, respiratory comorbidities, and pulmonary tuberculosis history. The C-indices for the overall, male-specific, and female-specific models were 0.829, 0.749, and 0.807, respectively. The 5-year AUC values were 0.785, 0.658, and 0.811, with Brier scores of 0.103, 0.176, and 0.059, respectively. Both 10-fold cross-validated C-indices and sensitivity analysis (excluding participants with a follow-up duration of <6 months) yielded C-indices were above 0.740. ConclusionThis study developed concise and practical overall and gender-specific COPD risk prediction models and corresponding nomograms. The models demonstrated robust performance in predicting COPD incidence, providing a valuable reference for identifying high-risk populations and formulating targeted screening and personalized management strategies.

		                        			ObjectiveTo investigate the effect of icariin (ICA) on steroid-induced ferroptosis in bone microvascular endothelial cells (BMECs). MethodsRat BMECs were selected and treated with 500 mg·L-1 hydrocortisone for 1.5 h to establish a ferroptosis model of BMECs. The experimental cells were divided into a blank group, hormone group (500 mg·L-1 hydrocortisone), ICA group (500 mg·L-1 hydrocortisone + 34 mg·L-1 ICA), and ferroptosis agonist group (500 mg·L-1 hydrocortisone + 34 mg·L-1 ICA + 2.7 mg·L-1 erastin). Cell viability was detected by CCK-8. The levels of ferrous ion, glutathione (GSH), malondialdehyde (MDA), superoxide dismutase (SOD), and reactive oxygen species (ROS) were detected by related kit species. The ferroptosis-related proteins, such as glutathione peroxidase 4(GPX4), ferritin light chain (FTL), and transferrin receptor protein1 (sTfR) were detected by Western blot, as well as autophagy-related proteins including microtubule-associated protein 1 light chain 3B (LC3B), Beclin1, B-cell lymphoma-2 (Bcl-2), and Caspase-3. Results500 mg·L-1 hydrocortisone intervention for 1.5 h could effectively induce ferroptosis in BMECs, and ferroptosis levels could reach a peak as the intervention continued. In terms of cellular antioxidant capacity, compared with those in the blank group, the cell vitality, GSH in the hormone group decreased significantly, and the levels of ROS, SOD, MDA, and ferrous ions were significantly increased (P<0.01). Compared with those in the hormone group, the cell viability, GSH were significantly increased, and the levels of ROS, SOD, MDA, and ferrous ions were decreased in the ICA group (P<0.01). Compared with those in the ICA group, the cell vitality, GSH in the ferroptosis agonist group decreased significantly, and the levels of ROS, SOD, MDA, and ferrous ions increased significantly (P<0.01). In terms of the relationship between ferroptosis and autophagy, compared with the blank group, the hormone group had significantly increased expression levels of LC3B, sTfR, Beclin1, and FTL and significantly decreased expression levels of GPX4 (P<0.01). Compared with the hormone group, The ICA group had significantly decreased expression levels of LC3B, sTfR, and FTL and significantly increased expression levels of Beclin 1 and GPX4 (P<0.01). Compared with those in the ICA group, the expression levels of LC3B, sTfR, and FTL increased in the rapamycin group, and those of Beclin 1 and GPX4 decreased (P<0.01). In terms of cell ferroptosis and apoptosis,compared with the blank group, the hormone group had significantly increased expression levels of FTL, sTfR and Caspase-3 and significantly decreased expression levels of GPX4, and Bcl-2 (P<0.01). Compared with the hormone group, the ICA group had significantly decreased expression levels of FTL, sTfR and Caspase-3 and significantly increased expression levels of GPX4, and Bcl-2 (P<0.01). Compared with those in the ICA group, the expression levels of FTL, sTfR and Caspase-3 in the ferroptosis agonist group were increased, and the expression levels of GPX4, and Bcl-2 were decreased (P<0.01). In terms of cell function,compared with that in the blank group, the ability of cell migration and tube formation was significantly decreased in the hormone group (P<0.01). Compared with that in the hormone group, the cell migration and tube formation ability in the ICA group were significantly increased (P<0.01). ConclusionFerroptosis is involved in steroid-induced damage in BMECs. ICA can inhibit steroid-induced ferroptosis in BMECs, and the mechanism may be associated with the inhibition of ferroptosis by regulating autophagy.

METHODS:(1)The cartilage tissues of the femur and tibia transected during knee arthroplasty were collected,and chondrocytes were isolated,cultured in vitro,and identified.(2)Cell counting kit-8 was used to detect the optimal intervention concentration of Complanatoside A in the concentration range of 0-160 μmol/L.(3)Chondrocytes were divided into blank group,sodium nitroprusside(1.5 mmol/L)-induced group,and sodium nitroprusside(1.5 mmol/L)+Complanatoside A(5 μmol/L)group.The viability and apoptosis rate of the cells in each group were detected by cell counting kit-8 and flow cytometry.The expression of type Ⅱ collagen and SOX9 was detected by immunofluorescence staining.The expression of apoptosis-related proteins and Wnt/β-catenin pathway proteins was detected by western blot assay. RESULTS AND CONCLUSION:The cells extracted in vitro were cultured and stained,and were clearly identified as chondrocytes.Complanatoside A had no obvious cytotoxicity to chondrocytes in the concentration range of 0-80 μmol/L,and significantly improved the chondrocyte viability in the concentration range of 2.5-10 μmol/L,especially when the concentration was 5 μmol/L.The apoptotic rate of chondrocytes was higher in the sodium nitroprusside-induced group than the blank control group,while the apoptotic rate was lower in the sodium nitroprusside+Complanatoside A group than the sodium nitroprusside-induced group.The fluorescence intensity of type Ⅱ collagen and SOX9 in chondrocytes was weaker in the sodium nitroprusside-induced group than the blank control group,while the fluorescence intensity of type Ⅱ collagen and SOX9 in the sodium nitroprusside+Complanatoside A group was higher than that of the sodium nitroprusside-induced group.In the sodium nitroprusside-induced group,the protein expression of Bax,Caspase-3,matrix metalloproteinase 13,Wnt3a,Wnt5a and β-catenin was higher than that of the blank control group,while the protein expression of Bcl-2 was lower than that of the blank control group.In the sodium nitroprusside+Complanatoside A group,except for the protein expression of Bcl-2 which was higher than that of the sodium nitroprusside-induced group,the expression of the other aforementioned proteins was lower than that of the sodium nitroprusside-induced group.To conclude,Complanatoside A has a certain inhibitory effect on chondrocyte apoptosis,which could regulate apoptosis-related proteins and promote the expression of chondrocyte regulatory factors,and presumably might play a role through inhibiting the Wnt/β-catenin signaling pathway.
