Introduction: Diabetic sensorimotor polyneuropathy (DSPN) is a common complication of long-standing diabetes mellitus marked by neuropathic pain and sensory deficits. Evidence supporting combination antioxidant and vitamin-based therapy remains limited, particularly in patients with chronic disease. This study aims to determine symptom improvement after 12 weeks of oral alpha-lipoic acid, vitamin B complex, and vitamin E (Bionerv E+) in chronic diabetic patients with symptomatic DSPN. Methodology: This single-centre, randomized, double-blind, placebocontrolled trial at HCTM enrolled 31 patients with symptomatic DSPN, assigned to Bionerv E+ (n = 16) or placebo (n = 15) for 12 weeks. Symptoms were assessed at baseline and post intervention using the Neuropathy Impairment Score–Lower Limb (NIS LL), Short Form McGill Pain Questionnaire (SF MPQ), Toronto Clinical Scoring System (TCSS), and nerve conduction studies (NCS). Results: A total of 31 participants were recruited; 18 completed the study (11 intervention, 7 placebo). The cohort was predominantly elderly (median age 68 ± 12 years), male (51.6%), with long-standing diabetes (mean duration of 18.6 ± 8.2 years), and a mean hemoglobin A1c of 7.3 ± 0.6%. A statistically significant reduction in TCSS score was observed in the intervention arm (5.5 ± 3.8 vs 3.3 ± 3.4; p = 0.002), indicating improvement in neuropathic symptom severity in this chronic population. The SF MPQ scores showed a downward trend in both arms, but were not statistically significant. Among intervention participants who completed sural NCS, three patients demonstrated normalization, and five showed partial amplitude gains, indicating directional improvement in nerve function. Four patients with normal baseline studies exhibited further amplitude gains. Otherwise, limited improvements were observed in those with abnormal conduction velocity parameters. Bionerv E+ was well tolerated, with only mild and self-limiting adverse events reported. Conclusion Short-term supplementation with Bionerv E+ showed improvement in neuropathic symptoms among longstanding diabetic patients. However, longer-term studies with larger cohorts are necessary to determine its effects on patients with DSPN.

INTRODUCTION

Despite advancements in surgical techniques aimed at preserving parathyroid function, postoperative hypocalcemia (PoH) remains a challenge following elective total thyroidectomy. Management typically involves postoperative calcium supplementation; however, some studies suggest preoperative calcium and/or vitamin D supplementation may prevent PoH. This paper analyzed existing studies to determine efficacy of preoperative calcium, with or without vitamin D, in preventing hypocalcemia in total thyroidectomy patients. Level of Evidence: Meta-analysis, Level IV.

A systematic review and meta-analysis was conducted with PROSPERO Registration No. CRD42024426410. Searches were performed on PubMED, PubMED Central, Embase, Cochrane Library, and HERDIN without date or language restrictions. Relevant studies underwent multiple screenings, with accepted individual studies assessed for bias or quality. Meta-analysis was performed using SPSS version 24.

A total of 345 studies were initially identified. Following deduplication, exclusion, and quality appraisal, 8 studies were included for analysis. Random effects model was utilized for all analysis due to heterogeneity in data. Results indicate that preoperative calcium, with or without vitamin D supplementation, correlated with higher postoperative calcium levels (z = 3.09, p < 0.001), reduced incidence of laboratory (z= 2.05, p = 0.03) and clinical hypocalcemia (z= 2.94, p < 0.001), and shorter hospital stay (z= 2.32, p = 0.01).

Results from the conducted meta-analysis support the proposed practice of providing calcium with or without vitamin D supplementation among patients who are to undergo total thyroidectomy procedures to prevent postoperative hypocalcemia.

OBJECTIVE: Epidemiological studies have shown that vitamin D status affects glycemic control in individuals with type 2 diabetes mellitus (T2DM). However, findings from intervention studies remain inconsistent. Therefore, a network meta-analysis was conducted to evaluate the comparative efficacy of various vitamin D supplementation strategies on glucose indicators in adults with T2DM. METHODS: Eligible studies published before September 12, 2024, were retrieved from PubMed, EMBASE, Cochrane Library, and Web of Science. A network meta-analysis of multiple dosage strategies-low (< 1,000 IU/day, LDS), medium (1,000-2,000 IU/day, MDS), high (2,000-4,000 IU/day, HDS), and extremely high (≥ 4,000 IU/day, EHDS)-was performed. RESULTS: The network meta-analysis of 40 RCTs indicated that, compared with placebo, vitamin D ₃ supplementation increased 25-hydroxyvitamin D [25-(OH)-D] levels, with pooled mean difference ( MD) showing a stepwise increase from LDS to EHDS. Ranking probabilities showed a corresponding rise in 25-(OH)-D levels from LDS (46.7%) to EHDS (91.2%). EHDS reduced fasting blood glucose (FBG) relative to no treatment. LDS significantly decreased hemoglobin A1c (HbA1c), and vitamin D ₂ significantly affected FBG levels. MDS led to a significant change in fasting insulin (FIN) compared to both placebo ( MD: -4.76; 95% CI -8.91 to -0.61) and no treatment ( MD: -7.30; 95% CI -14.44 to -0.17). CONCLUSION The findings suggest that vitamin D supplementation may be a viable approach for improving glycemic control in adults with T2DM, with lower doses potentially offering benefit. The analysis also showed a dose-dependent increase in 25-(OH)-D levels.

Sucrose non-fermenting 1-related protein kinase 1 (SnRK1) is one of the highly conserved Ca²⁺ non-dependent serine/threonine protein kinases, playing a crucial role in regulating the stress responses, growth, and development of plants. SnRK1 is a three-subunit complex, and it is involved in responding to the signaling transduction induced by low-energy/low-sugar conditions. SnRK1 responds biotic and abiotic stress conditions (such as salt, drought, low/high temperatures, and diseases) through phosphorylation of key metabolic enzymes and regulatory proteins, regulation of transcription, and interactions with other proteins. Furthermore, SnRK1 is not only involved in hormone signaling pathways mediated by abscisic acid (ABA), jasmonic acid (JA) and salicylic acid (SA), but also regulates plant autophagy by inhibiting the activity of target of rapamycin (TOR). In this review, we summarized the current results of research on the discovery, structure, and classification of plant SnRK1 and its roles in the stress responses, growth, and development of plants. Furthermore, this article proposes the directions of future research. This review provides good genetic resources and a theoretical basis for the genetic improvement and biological breeding for enhancing the stress tolerance of crops.

Calcineurin B-like protein (CBL)-interacting protein kinases (CIPKs) are a group of Ser/Thr protein kinases, playing a crucial role in the growth, development, and stress responses of plants. CIPKs can undergo autophosphorylation or target the phosphorylation of other signaling factors in responses to biotic and abiotic stresses. In addition, they are involved in the signaling pathways of plant hormones such as abscisic acid (ABA), gibberellic acid (GA), ethylene (ETH), and salicylic acid (SA) to regulate plant growth and development. Furthermore, CIPKs respond to stresses such as salinity, drought, cold, and heavy metals by forming complexes through specific interactions with CBLs. In this study, we summarized the discovery, structures, classification, regulatory mechanisms, and roles of CIPKs in plant responses to stresses and made an outlook on the future research directions. This review is expected to provide genetic resources and theoretical foundations for the genetic improvement and breeding of crops with stress tolerance.

Rice (Oryza sativa L.) is an important food crop. The appearance of lesion mimics in rice leads to phytohormone disorders, which affects rice adaptation to environmental stresses and ultimately reduces the yield and quality. To explore whether the changes in the adaptability of rice lesion-mimic mutants to stressful environments are caused by the disorder of phytohormone metabolism in plants. In this study, we screened an ethyl methane sulfonate-treated population of the japonica cultivar 'Taipei 309' for a mutant with rust-like spots on leaves at the early tillering stage and brown-red spots at maturity and named it rsl1 (rust spotted leaf 1). Compared with the wild type, rsl1 showed decreases in plant height, panicle length, primary branch number, secondary branch number, filled grains per panicle, seed-setting rate, and 1 000-grain weight, and an increase in number of effective panicles. Genetic analysis indicated that rsl1 was controlled by a single recessive nuclear gene. RSL1 was localized between two molecular markers, B7-7 and B7-9, on rice chromosome 7 by map-based cloning. PCR sequencing of the annotated genes in this interval revealed a mutation of C1683A on the eighth exon of SPL5 (LOC_Os07g10390) in rsl1, which resulted in premature termination of protein translation. Exogenous phytohormone treatments showed that rsl1 was less sensitive to salicylic acid (SA), abscisic acid (ABA), and indo-3-acetic acid (IAA) and more sensitive to methyl jasmonate (MeJA) and gibberellin acid (GA) than the wild type. In addition, the survival rate of rsl1 was lower than that of the wild type under salt, alkali, drought, and high temperature stresses, and it was higher than that of the wild type under cold stress. Quantitative real-time polymerase chain reaction (qRT-PCR) results showed that RSL1 was involved in the regulation of ABA, SA, MeJA, IAA, and GA-related genes under abiotic stresses. The present study showed that the RSL1 mutation led to the appearance of lesion mimics and affected the growth, development, and stress resistance of rsl1 under abiotic stresses. The study of the functional mechanism of this gene can provide theoretical guidance for the research on rice stress resistance.

Retinopathy of prematurity (ROP) is a proliferative retinal vascular disease that threatens the vision of premature infants. Various novel drugs have demonstrated therapeutic potential for ROP by targeting signaling pathways associated with vascular endothelial growth factor (VEGF) [such as PI3K/AKT, hypoxia-inducible factor (HIF)-1α/VEGF], oxidative stress, tumor necrosis factor (TNF)-α, and Notch pathways. Propranolol, insulin-like growth factor-1, and celecoxib attenuate pathological neovascularization via the PI3K/Akt signaling pathway. Tripterine and melatonin inhibit retinal neovascularization by modulating the HIF-1α/VEGF signaling axis. Adiponectin mitigates the damage caused by oxidative stress and preserves endothelial function by enhancing endothelial nitric oxide synthase activity. Omega-3 polyunsaturated fatty acids suppress TNF-α-mediated inflammatory responses, modulate retinal development and angiogenesis, and reduce retinal neovascular lesions. DAPT, a γ-secretase inhibitor, blocks Notch signaling to suppress abnormal vascular proliferation. These agents exhibit synergistic multi-pathway anti-angiogenic effects in preclinical models and early-phase clinical trials, offering critical insights for advancing drug development and clinical translation in ROP management.

Recent data suggest that vascular endothelial growth factor receptor inhibitor (VEGFRi) can enhance the anti-tumor activity of the anti-programmed cell death-1 (anti-PD-1) antibody in colorectal cancer (CRC) with microsatellite stability (MSS). However, the comparison between this combination and standard third-line VEGFRi treatment is not performed, and reliable biomarkers are still lacking. We retrospectively enrolled MSS CRC patients receiving anti-PD-1 antibody plus VEGFRi (combination group, n=54) or VEGFRi alone (VEGFRi group, n=32), and their efficacy and safety were evaluated. We additionally examined the immune characteristics of the MSS CRC tumor microenvironment (TME) through single-cell and spatial transcriptomic data, and an MSS CRC immune cell-related signature (MCICRS) that can be used to predict the clinical outcomes of MSS CRC patients receiving immunotherapy was developed and validated in our in-house cohort. Compared with VEGFRi alone, the combination of anti-PD-1 antibody and VEGFRi exhibited a prolonged survival benefit (median progression-free survival: 4.4 vs. 2.0 months, P=0.0024; median overall survival: 10.2 vs. 5.2 months, P=0.0038) and a similar adverse event incidence. Through single-cell and spatial transcriptomic analysis, we determined ten MSS CRC-enriched immune cell types and their spatial distribution, including naive CD4⁺ T, regulatory CD4⁺ T, CD4⁺ Th17, exhausted CD8⁺ T, cytotoxic CD8⁺ T, proliferated CD8⁺ T, natural killer (NK) cells, plasma, and classical and intermediate monocytes. Based on a systemic meta-analysis and ten machine learning algorithms, we obtained MCICRS, an independent risk factor for the prognosis of MSS CRC patients. Further analyses demonstrated that the low-MCICRS group presented a higher immune cell infiltration and immune-related pathway activation, and hence a significant relation with the superior efficacy of pan-cancer immunotherapy. More importantly, the predictive value of MCICRS in MSS CRC patients receiving immunotherapy was also validated with an in-house cohort. Anti-PD-1 antibody combined with VEGFRi presented an improved clinical benefit in MSS CRC with manageable toxicity. MCICRS could serve as a robust and promising tool to predict clinical outcomes for individual MSS CRC patients receiving immunotherapy.

Primary pulmonary nuclear protein of the testis (NUT) midline carcinoma (NMC) is a rare and highly aggressive thoracic malignancy that poses significant diagnostic and therapeutic challenges in clinical practice. This tumor is characterized by its heterogeneous clinical presentations and poor prognosis, often evading accurate initial diagnosis. In this study, we present two cases of primary pulmonary NMC treated with an integrated therapeutic approach combining anti-angiogenic agents, platinum-based chemotherapy, and radiotherapy. This multimodal strategy achieved survival durations of 32 and 13 months, respectively, surpassing the currently reported median survival of advanced NMC. Through a systematic literature review of reported cases, we have summarized the currently used diagnostic methods and treatment modalities for NMC. Our findings suggest that multimodal therapy incorporating anti-angiogenic treatment may offer superior clinical outcomes compared to conventional monotherapy regimens, particularly for patients who are not eligible for surgery. This comprehensive investigation enhances our understanding of NMC management by elucidating diagnostic pitfalls through histopathological correlation and proposing an effective therapeutic combination that demonstrates improved survival outcomes. By providing valuable insights into the diagnosis and treatment of primary pulmonary NMC, we hope to contribute to the development of more effective strategies for managing this rare and aggressive malignancy.

This study identified 8 members including NjBIN2 of the GSK3 family in Nardostachys jatamansi by bioinformatics analysis. Moreover, the phylogenetic tree revealed that the GKS3 family members of N. jatamansi had a close relationship with those of Arabidopsis. RT-qPCR results showed that NjBIN2 presented a tissue-specific expression pattern with the highest expression in roots, suggesting that NjBIN2 played a role in root growth and development. In addition, the application of epibrassinolide or the brassinosteroid(BR) synthesis inhibitor(brassinazole) altered the expression pattern of NjBIN2 and influenced the photomorphogenesis(cotyledon opening) and root development of N. jatamansi, which provided direct evidence about the functions of NjBIN2. In conclusion, this study highlights the roles of BIN2 in regulating the growth and development of N. jatamansi by analyzing the expression pattern and biological function of NjBIN2. It not only enriches the understanding about the regulatory mechanism of the growth and development of N. jatamansi but also provides a theoretical basis and potential gene targets for molecular breeding of N. jatamansi with improved quality in the future.
