The crystalline lens of the eye is recognized as one of the most radiosensitive tissues in the human body. While the International Commission on Radiological Protection (ICRP) has classified ionizing radiation (IR)-induced cataracts as a tissue reaction (deterministic effect) and subsequently reduced the occupational equivalent dose limit for the lens, significant uncertainties remain regarding the precise dose threshold and the complex biological pathways driving lens opacification. This review provides a comprehensive synthesis of current knowledge concerning radiation-induced lens damage, integrating epidemiological exposure characteristics with dose-response modeling and mechanistic molecular insights. First, we analyze exposure characteristics through four epidemiological dimensions: dose, time, space, and population. Clinical evidence suggests that radiation cataracts—particularly posterior subcapsular opacities—exhibit a distinct latency period that is inversely correlated with dose. We highlight that risk is not confined to acute high-dose scenarios (such as in atomic bomb survivors) but is increasingly relevant in chronic low-dose occupational settings (e.g., interventional radiology) and medical diagnostics (e.g., CT scans). Crucially, individual susceptibility is modified by genetic background, age, and environmental co-factors, complicating risk assessment. Second, we critically examine the dose-effect relationship. Although the ICRP suggests a threshold of 0.5 Gy, emerging data challenge the traditional threshold model, with some studies advocating for a linear non-threshold (LNT) relationship. We further discuss the critical roles of radiation quality and dose rate. High linear energy transfer (LET) radiation demonstrates a significantly higher relative biological effectiveness (RBE) for cataractogenesis compared to low-LET radiation. Paradoxically, and unlike many other tissues, the lens may exhibit an “inverse dose-rate effect,” where fractionated or protracted exposures potentially enhance biological damage—a finding that challenges classical radiobiological paradigms. Third, drawing upon the “cataractogenic load” hypothesis and the unique physiological constraints of the lens, this review elucidates the multidimensional molecular mechanisms driving radiation-induced opacification. Key mechanisms include four aspects. (1) DNA damage and repair: IR induces DNA double-strand breaks (DSBs) that, due to the lens’ limited repair capacity (modulated by genes such as ATM, Ptch1, and Ercc2), lead to the accumulation of damage. (2) Antioxidant defense system: dysfunction of the Nrf2/HO-1 antioxidant axis results in redox imbalances, triggering NF-κB-mediated inflammation and protein aggregation. (3) Cell proliferation and senescence: IR disrupts cell cycle regulation, causing a dichotomy of effects—driving premature senescence in some cell populations (evidenced by ATM nuclear foci) while inducing aberrant proliferation via growth factor upregulation (FGF2, TGFβ) in others. (4) Cell migration and adhesion: activation of the Wnt/β‑catenin pathway and alterations in the E-cadherin complex promote the abnormal migration of epithelial cells to the posterior capsule, a hallmark of radiation-induced cataracts. In conclusion, radiation-induced cataractogenesis is a multifactorial process in which genetic susceptibility and environmental stressors converge to overwhelm the lens’ homeostatic thresholds. Future research must prioritize longitudinal cohort studies to refine dose thresholds and employ multi-omics approaches to map the crosstalk between DNA damage responses and matrix remodeling. Establishing a robust mechanistic model is essential for developing targeted radioprotective strategies and optimizing radiation protection standards for occupational and medical safety.

This article systematically analyzes the historical evolution of the name, origin, medicinal parts, producing area, harvesting and processing, nature, flavor and efficacy of Piperis Longi Fructus by referring to the materia medica, medical books, and prescription books of past dynasties, combined with the relevant modern literature, in order to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the herbal textual research, the name of Piper longum first appeared in Nanfang Caomuzhuang, and it also has other aliases such as Biboli, Halou, and Hujiaohua. Historically, the origin of Piperis Longi Fructus has been P. longum of the Piperaceae family. In ancient times, both the fruit and root were used as medicine, and since the Republic of China, the fruit has been mainly used as medicine. The medicinal part is the dried, nearly ripe or ripe fruit spikes. Piperis Longi Fructus is native to India and has been introduced into China since the Tang dynasty. In the Ming dynasty, Bencao Pinhui Jingyao clearly stated that the genuine producing area was "Duanzhou", present-day Zhaoqing in Guangdong province. Nowadays, it is planted in Guangdong, Guangxi, Hainan, Yunnan and other regions. Historically and currently, harvesting occurs in autumn. The ancient processing method uniformly involved removing the stems, soaking in the sourest vinegar overnight, baking, and scraping off the peels and grains with a knife until clean. In modern times, impurities are removed, and it is dried in the sun and crushed when used. The properties, functions and applications of P. longum are basically the same in ancient and modern times. It tastes pungent, is warm in nature, and non-toxic. It has the effects of warming the middle-jiao to dispel cold, lowering Qi and relieving pain, and is used for cold pain in the epigastrium and abdomen, vomiting, diarrhea, chest pain, headache, and toothache. Based on the research results, it is recommended that when developing famous classical formulas containing Piperis Longi Fructus, the dried nearly ripe or ripe fruit spikes of P. longum should be used. If there are no clear processing requirements, it is recommended to use the raw products for medicinal use, and the specific processing methods can refer to the relevant requirements under Piperis Longi Fructus in the 2025 edition of the Pharmacopoeia of the People's Republic of China. If processing requirements such as soaking in vinegar and peeling are clearly specified, it is recommended to follow the ancient methods.

Objective To investigate the cross-sectional associations between different fatty liver classifications and cardiac structure and function in people undergo health examination. Methods A total of 6 545 adults who underwent health examinations at the Health Management Center of Zhongshan Hospital, Fudan University between January 1 and December 31, 2017, were retrospectively included. Demographic characteristics and laboratory data were collected. The hepatic steatosis was graded by ultrasonography. And patients with fatty liver were further stratified according to alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels, as well as the degree of liver fibrosis. Cardiac morphology and function were assessed by transthoracic echocardiography, and left ventricular geometric patterns were classified accordingly. Multivariate logistic regression analysis was performed to evaluate the associations between fatty liver classifications and cardiac abnormalities. Results There were 2 795 patients (42.7%) with fatty liver, of whom 832 (29.8%) had significant cardiac structural alterations and 1 500 (53.7%) had diastolic dysfunction. Severe fatty liver was risk factor for concentric remodeling and increased relative wall thickness (RWT), with odds ratios (ORs) of 1.27 (P=0.012) and 1.27 (P=0.009), respectively. Fatty liver accompanied by elevated ALT or AST was risk factor for concentric remodeling (OR=1.45,1.56; P=0.001, 0.001), increased RWT (OR=1.48,1.57; P<0.001, <0.001), and diastolic dysfunction (OR=1.27, 1.32; P=0.035, 0.040), respectively. Fatty liver with liver fibrosis was risk factor for concentric remodeling (OR=1.83, P=0.046) and diastolic dysfunction (OR=2.64, P=0.034). Conclusions Advanced fatty liver, including severe hepatic steatosis, accompanied by elevated liver enzymes or liver fibrosis, could increase risks of cardiac remodeling and diastolic dysfunction, while systolic function is preserved. For patients with fatty liver, it is recommended to undergo regular ultrasonography examination.

Effective symptom management can alleviate the physical and psychological distress experienced by patients with cancer, improve quality of life, and contribute to treatment adherence and improve clinical outcomes. However, most existing guidelines are developed for healthcare professionals, and patients and the public have limited access to standardized and comprehensible guidance on symptom management. To address this gap and to facilitate effective communication and shared decision-making, this study proposes the development of a patient version of the cancer symptom management guideline. The development process will adhere to the methodological framework recommended by the Guidelines International Network and the World Health Organization. The GRADE approach will be employed to assess the certainty of evidence and to formulate recommendations. In addition, the process will be informed by the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument and the Reporting Items for Practice Guidelines in Healthcare-Public or Patient Versions of Guidelines (RIGHT-PVG). This protocol outlines the establishment of the guideline working group, the identification and prioritization of key questions, evidence retrieval and appraisal, and the formulation of recommendations, with the aim of ensuring methodological rigor and transparency in the development of the patient guideline and providing methodological reference for similar guideline initiatives.

OBJECTIVE To quantitatively assess the compatibility risk of commonly used intravenous drugs in intensive care unit (ICU) patients with severe pneumonia, and provide a reference for reducing the incidence of adverse events caused by incompatibility. METHODS The PASS clinical pharmacy management system was used to retrospectively collect the data of patients diagnosed with “severe pneumonia” in the ICU of Hebei General Hospital from January 2023 to June 2025, and the commonly used intravenous drugs and medication frequency were extracted. Based on authoritative databases such as Micromedex and Stabilis as well as relevant literature, the compatibility data of commonly used intravenous drugs with 0.9% Sodium chloride injection and 5% Glucose injection were summarized. The theoretical and actual compatibility risk values were calculated using formulas, and high-risk drugs were screened and the compatibility query table was drawn. RESULTS A total of 158 ICU patients with severe pneumonia were treated with 89 intravenous drugs, and 24 drugs with high compatibility risk were identified. The drug with the highest theoretical compatibility risk value was Amphotericin B for injection (risk value 146), and the drug with the highest actual compatibility risk value was Propofol medium and long chain fat emulsion injection (risk value 8 740). Among the 24 high-risk drugs, six drugs, namely Esomeprazole sodium for injection, Ambroxol hydrochloride injection, Midazolam injection, Methylprednisolone sodium succinate for injection, Furosemide injection, and Cefoperazone sodium and sulbactam sodium for injection, simultaneously ranked among the top 15 in both theoretical and actual compatibility risk rankings. Among 650 pairwise compatibility combinations of the 24 drugs, 24.62% were compatible, 11.23% were incompatible, 6.77% had conflicting evidence, and 57.38% had missing evidence. CONCLUSIONS This study quantitatively analyzed the medication safety of commonly used intravenous drugs in ICU patients with severe pneumonia, identified 24 drugs with high compatibility risk, and established a compatibility query table for high-risk drugs, which helps reduce the risk of ICU compatibility adverse events.

Metabolic dysfunction-associated fatty liver disease (MAFLD) has become the most common chronic liver disease worldwide. Its pathological process is centered on the “two-hit” theory, with gut-liver axis dysregulation running through the entire disease course from steatosis to liver cirrhosis and even hepatocellular carcinoma, and it forms an extensive cross-system regulatory mechanism with the metabolic, cardiovascular, renal, and psychological and nervous systems through multi-dimensional pathways such as the “gut-liver-brain axis”, the “liver-kidney axis”, and the “liver-heart axis”. Disease progression is not limited to the liver itself, and it also involves functional imbalance of multiple organ systems throughout the body. This article systematically elaborates on the association mechanism of “liver pathological progression-multi-axis regulation-comorbidity occurrence” in MAFLD, proposes synergistic management strategies integrating early screening based on risk stratification, targeted intervention, and multidisciplinary diagnosis and treatment, and analyzes the limitations of current research and future development directions, in order to provide a theoretical basis and practical guidance for precise diagnosis and treatment and individualized management of MAFLD.

ObjectiveTo interpret the main contents of the Expert Consensus on Clinical Application of Yifei Zhike Capsules (hereinafter referred to as the Consensus), analyze its evidence basis, and explore future research directions, thus providing a reference for rational drug use in clinical practice. MethodsThe core contents of the Consensus are summarized. Focusing on clinical issues, this paper summarizes the recommendations and consensus suggestions in the Consensus and explains them from aspects such as indications, key advantages, usage and dosage, combined medication, contraindications, precautions, and safety. ResultsThe Consensus clearly states that Yifei Zhike capsules can be used for acute or chronic bronchitis, pulmonary tuberculosis and other respiratory system diseases. It for the first time proposes that the applicable TCM syndrome of Yifei Zhike capsules is Qi-Yin deficiency together with combined phlegm and stasis. For different diseases, the Consensus provides specific usage instructions, dosage, and treatment course recommendations, supplementing the contents not covered in the drug instructions. In terms of combined medication, the Consensus emphasizes the principle of using this drug in combination with standardized chemotherapy regimens or conventional Western medicines and the applicability for the treatment of pulmonary tuberculosis and moderate to severe acute or chronic bronchitis. In terms of safety, the Consensus proposes methods for identifying common adverse reactions, drug contraindications, and precautions based on a review of the existing data and preliminarily builds a risk management framework. However, the evidence on which the Consensus is based are mostly early studies, with small sample sizes, which result in the low evidence grades (mainly C and D) of some recommendations. ConclusionThe Consensus provides specific guidance for the clinical use of Yifei Zhike capsules. However, due to the limited quality of the existing research evidence, more high-quality clinical studies are needed in the future to further verify its efficacy, safety, and explore its broader application prospects.

Background:
Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients.
Methods:
Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines.
Results:
Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher.
Conclusion
MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Disruption of the intestinal mucosal barrier caused by gut dysbiosis and metabolic imbalance is the underlying pathology of inflammatory bowel disease (IBD). Traditional Chinese medicine Wuji Wan (WJW) is commonly used to treat digestive system disorders and showed therapeutic potential for IBD. In this interdisciplinary study, we aim to investigate the pharmacological effects of WJW against experimental colitis by combining functional metabolomics and gut-microbiota sequencing techniques. Treatment with WJW altered the profile of the intestinal microbiota and notably increased the abundance of Lactobacillus, thereby facilitating the conversion of tryptophan into indole-3-acetic acid (IAA) and indoleacrylic acid (IA). These indole derivatives activated the aryl hydrocarbon receptor (AhR) pathway, which reduced colonic inflammation and restored the expression of intestinal barrier proteins. Interestingly, the beneficial effects of WJW on gut barrier function improvement and tryptophan metabolism were disappeared in the absence of gut microbiota. Finally, pre-treatment with the AhR antagonist CH-223191 confirmed the essential role of IAA-mediated AhR activation in the therapeutic effects of WJW. Overall, WJW enhanced intestinal barrier function and reduced colonic inflammation in a murine colitis model by modulating Lactobacillus-IAA-AhR signaling pathway. This study provides novel insights into colitis pathogenesis and presents an effective therapeutic and preventive approach against IBD.
