Intravascular large B-cell lymphoma(IVLBCL) is a rare and aggressive type of lymphoma with diverse and nonspecific clinical manifestations, often leading to misdiagnosis. This article reports a case of IVLBCL in a middle-aged male patient who initially presented with pulmonary arterial hypertension(PAH). The patient exhibited progressive hypoxemia and PAH, showing poor response to standard PAH therapy. Laboratory tests indicated a hyperinflammatory state and significantly elevated lactate dehydrogenase levels, while imaging revealed diffuse bilateral lung lesions. Random skin biopsy identified atypical B lymphocytes within subcutaneous capillaries, confirming the diagnosis of IVLBCL. Following treatment with the ZR-CHOP regimen, the patient's symptoms and laboratory parameters improved markedly. By reviewing relevant literature, this article systematically outlines the diagnostic and therapeutic process of this case, aiming to provide insights for the clinical recognition of such rare presentations.

Objective To clarify the role and underlying mechanism of macrophage-to-myofibroblast transition (MMT) in renal fibrosis that develops after acute kidney injury (AKI) induced by ischemia-reperfusion injury (IRI). Methods Mouse AKI model was generated by renal ischemia-reperfusion. Animals were randomized into control (Con), sham operated (Sham), and IRI groups sacrificed at 1 d (IRI 1 d), 3 d (IRI 3 d) and 14 d (IRI 14 d) after reperfusion (n = 5). Renal injury was assessed by renal coefficient, serum creatinine (Scr) and kidney injury molecule-1 (KIM-1). Periodic acid-Schiff (PAS) staining was used to evaluate tubular damage and inflammatory infiltration. Masson staining and immunohistochemistry were employed to quantify collagen deposition, α-smooth muscle actin (α-SMA) and type I collagen (COL I). Flow cytometry was used to determine macrophage infiltration and phenotype. MMT was identified by flow cytometry plus immunofluorescence. Transforming growth factor (TGF)-β1/Smad3 pathway proteins were examined by Western blotting. Results Compared with Sham group, renal coefficient, Scr and KIM-1 rose in IRI 1 d group, renal coefficient and KIM-1 remained elevated in IRI 3 d group. Compared with the IRI 1 d group, the renal coefficient and KIM-1 decreased in the IRI 14 d group. Compared with the IRI 3 d group, the renal coefficient, Scr and KIM-1 decreased in the IRI 14 d group (all P < 0.05). PAS revealed the most severe tubular injury at IRI 3 d. Masson staining showed progressively increasing collagen deposition, while immunohistochemistry demonstrated α-SMA and COL I rising from day 1 and persisting to day 14 (all P < 0.05). Macrophage infiltration increased from day 1 and lasted to day 14 (P < 0.05). M1 macrophages peaked at day 1 then declined, whereas M2 macrophages increased at day 3 and remained high through day 14 (P < 0.05). MMT began to rise at day 3 and continued to day 14 and M2 macrophages were the predominant source of MMT cells (all P < 0.05). Compared with Sham group, TGF-β1 protein was up-regulated and p-Smad3/Smad3 ratio was elevated in all IRI groups (all P < 0.05). Conclusions M2 macrophages promote post-IRI-AKI renal fibrosis via MMT, a process closely linked to activation of the TGF-β1/Smad3 signaling pathway.

Lung cancer is a leading cause of cancer-related morbidity and mortality worldwide. Coupled with the substantial workload, the clinical management of lung cancer is challenged by the critical need to efficiently and accurately process increasingly complex medical information. In recent years, large language models (LLMs) technology has undergone explosive development, demonstrating unique advantages in handling complex medical data by leveraging its powerful natural language processing capabilities, and its application value in the field of lung cancer diagnosis and treatment is continuously increasing. The paper systematically analyzes that the exceptional potential of LLMs in lung cancer auxiliary diagnosis, tumor feature extraction, automatic staging, progression/outcome analysis, treatment recommendations, medical documentation generation, and patient education. However, they face critical technical and ethical challenges including inconsistent performance in complex integrated decision-making (e.g., TNM staging, personalized treatment suggestions) and "black box" opacity issues, along with dilemmas such as training data biases, model hallucinations, data privacy concerns, and cross-lingual adaptation challenges ("data colonization"). Future directions should prioritize constructing high-quality multimodal corpora specific to lung cancer, developing interpretable and compliant specialized models, and achieving seamless integration with existing clinical workflows. Through dual drivers of technological innovation and ethical standardization, LLMs should be prudently advanced for holistic lung cancer management processes, ultimately promoting efficient, standardized, and personalized diagnosis and treatment practices.

OBJECTIVE To investigate the immunotoxicity and potential mechanism of Carthamus tinctorius extract on RBL-2H3 cells via direct induction and induction by sensitized serum prepared with an overdose of the extract. METHODS For direct induction by C. tinctorius extract, RBL-2H3 cells were divided into normal control group (no treatment) and C. tinctorius extract group (10 mg/mL). For induction by sensitized serum prepared with an overdose of C. tinctorius extract, rats were divided into normal control group (no treatment), adjuvant-treated group (1 mL adjuvant), C. tinctorius extract-induced sensitization group (2.04 g/mL), and ovalbumin (OVA)-induced sensitization group (50 mg/mL). Sensitization was performed once every other day for a total of 3 times. Morphological changes of RBL-2H3 cells were observed, the degranulated rate of cells was counted, and histamine content was determined; the release rate of β -hexosaminidase ( β -Hex) was calculated, the levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) and intracellular Ca²⁺ concentration were detected. RESULTS Under direct induction by C. tinctorius extract, compared with the normal control group, the volume of cells in the C. tinctorius extract group was significantly reduced and cell density decreased; the degranulation rate of cells, histamine content, β -Hex release rate, IL-6 and TNF-α levels, as well as intracellular Ca²⁺ concentration were all significantly increased ( P <0.01). Under i nduction by sensitized serum prepared with an overdose of C. tinctorius extract, compared with the adjuvant-treated group, the above indicators in the C. tinctorius extract-induced sensitization group and the OVA-induced sensitization group showed consistent changes with those in the C. tinctorius extract group under direct induction, all being significantly elevated ( P <0.01). CONCLUSIONS C. tinctorius extract may affect degranulation of RBL-2H3 cells and promote Ca²⁺ influx accompanied by the release of pro-inflammatory cytokines through two approaches: direct induction and induction by sensitized serum prepared under overdose administration. Its mechanism may be related to the activation of the calcium signaling pathway and the regulation of inflammatory pathways under the synergistic effect of multiple components.

OBJECTIVE To evaluate the efficacy and safety of amoxicillin combined with proton pump inhibitor (PPI) or potassium-competitive acid blocker (P-CAB) for Helicobacter pylori (Hp) eradication. METHODS Randomized controlled trial (RCTs) on amoxicillin combined with PPI or P-CAB for Hp eradication were retrieved from PubMed, Embase, the Cochrane Library, Web of Science, CNKI, Wanfang, and VIP data. The search time frame was from database inception to September 5, 2025. After literature screening, data extraction, and quality assessment, a network meta-analysis was performed using Stata 17.0 software. RESULTS A total of 12 RCTs involving 5 515 patients were included, encompassing 8 therapeutic regimens: PPI combined with high-dose amoxicillin for 14 days (TR1), PPI combined with low-dose amoxicillin for 14 days (TR2), P-CAB combined with high-dose amoxicillin for 7 days (TR3), P-CAB combined with high-dose amoxicillin for 14 days (TR4), P-CAB combined with high-dose amoxicillin for 10 days (TR5), P-CAB combined with low-dose amoxicillin for 7 days (TR6), P-CAB combined with low-dose amoxicillin for 14 days (TR7), and P-CAB combined with low-dose amoxicillin for 10 days (TR8). The network meta-analysis results showed that, in terms of intention-to-treat Hp eradication rates, the eradication rates of TR5 and TR4 were significantly higher than those of TR3, TR8, TR6 and TR1 ( P <0.05). The surface under the cumulative ranking curve (SUCRA) values from highest to lowest were: TR4 (89.7%)>TR5 (82.3%)>TR7 (71.5%)> TR2 (48.6%)>TR1 (43.9%)>TR8 (28.7%)>TR3 (22.7%)>TR6 (12.6%). Regarding safety, the incidence of adverse reactions in TR3 and TR5 was significantly lower than that in TR1 ( P <0.05). The SUCRA values from highest to lowest were: TR1 (91.3%)>TR4 (79.8%)>TR5 (55.0%)>TR7 (50.9%)>TR8 (41.3%)>TR2 (36.4%)>TR3 (27.6%) >TR6 (17.7%). CONCLUSIONS Although the regimen of P-CAB combined with high-dose amoxicillin for 14 days demonstrates the best efficacy, the combination of P-CAB with high-dose amoxicillin for 10 days exhibits a better balanced profile in terms of both efficacy and safety.

OBJECTIVE To provide a reference for anticoagulation therapy, adverse drug reaction monitoring, and individualized medication adjustment in complex cases, such as those with thrombocytopenia following bioprosthetic heart valve replacement. METHODS Clinical pharmacists participated in the pharmaceutical care of a patient with thrombocytopenia following bioprosthetic heart valve replacement. For cardiac insufficiency, the pharmacists recommended maintaining oral bisoprolol, sacubitril/valsartan, spironolactone, furosemide, and potassium chloride, with levosimendan added to enhance myocardial contractility, while monitoring blood pressure, heart rate and serum potassium levels. For thrombocytopenia, based on literature- based risk assessment, the pharmacists advised administering recombinant human interleukin-11 (rhIL-11), platelet transfusion, and employing anticoagulation therapy with nadroparin calcium bridging to warfarin, with warfarin dosage adjusted according to the international normalized ratio (INR). For rapid ventricular rate atrial fibrillation, amiodarone and digoxin were recommended. For acute liver injury, suspected to be induced by amiodarone and rhIL-11, the pharmacists suggested discontinuing the relevant drugs and treating with ademetionine 1,4-butanedisulfonate combined with polyene phosphatidylcholine for liver protection treatment. The patient received anticoagulation medication education emphasizing strict INR monitoring and close observation for bleeding or thrombotic events. RESULTS The clinicians adopted these recommendations. Following the intervention, the patient’s liver function showed significant improvement, with alanine aminotransferase decreasing to 70 U/L and aspartate aminotransferase to 42 U/L. The ventricular rate stabilized at 70-100 beats per minute, cardiac function remained stable, the INR was maintained within the target range of 1.80-2.50, and the patient was ultimately discharged with improved condition. CONCLUSIONS Through balancing anticoagulation and bleeding risks, the clinical pharmacists applied pharmaceutical expertise to assist in developing personalized anticoagulation regimens, conducted adverse drug reaction monitoring and evaluation, and optimized medication strategies, thereby effectively ensuring patient safety and therapeutic efficacy.

Chinese Journal of School Health 2026;47(4):517-521
Objective:
To understand the current status and associated factors of sleep problems among preschool children in Hainan Province, so as to provide scientific evidence for improving sleep health in this population.
Methods:
From January 2021 to June 2022, a total of 4 105 preschool children aged 3-6 years from 62 kindergartens in Hainan Province were selected using stratified cluster random sampling method. Demographic information and lifestyle habits were collected through the Hainan Province Child Growth and Development Survey Questionnaire. The Children s Sleep Habits Questionnaire (CSHQ) was employed to assess sleep status. Unconditional binary Logistic regression model was applied to investigate the associated factors of sleep problems among preschool children.
Results:
The overall CSHQ score for children was 58.03±18.84, with 80.95% of preschool children exhibiting sleep related issues. The top three most prevalent sleep problem domains were bedtime resistance (72.42%), sleep anxiety ( 54.88 %), and parasomnias (38.86%). Logistic regression analysis revealed that higher family annual income ( OR=0.60, 95%CI = 0.45-0.79), higher maternal education level ( OR=0.53, 95%CI =0.32-0.89), regular or daily vitamin D supplementation ( OR=0.77, 95%CI =0.60-0.99), and fully self initiated eating behavior ( OR=0.71, 95%CI =0.59-0.85) were negatively related with children s sleep problems; in addition, screen exposure ( OR=1.27, 95%CI =1.06-1.51) and picky eating ( OR= 1.47 , 95%CI =1.21-1.78) were positively related to children s sleep problems (all P <0.05).
Conclusion
The high detection rate of sleep problems among preschool children in Hainan Province is multifactorially associated with family environment, dietary habits, and lifestyle behaviors.

OBJECTIVE To analyze trends in the burden of disease associated with falls from 1990 to 2023, identify risk factors for falls, and provide a reference for the development of measures to reduce the burden of disease associated with falls and the formulation of public health policies. METHODS Based on the data of 2023 from the Global Burden of Disease (GBD) database, the changes in fall-related prevalence, mortality, disability-adjusted life years (DALYs) and incidence in China and globally from 1990 to 2023 were analyzed, and the stratified analyses by gender, age and socio-demographic index (SDI) were conducted. The risk factors related to falls in 2023 were systematically analyzed, and the impact of multimorbidity and polypharmacy on the occurrence of falls by combining relevant literature evidence was explored. RESULTS & CONCLUSIONS Globally, the percentage changes in age-standardized rates of fall-related prevalence, mortality, DALYs and incidence from 1990 to 2023 were -2.4% (95%UI: -4.8% to -0.3%), -7.8% (95%UI: -20.5% to 10.9%), -10.6% (95%UI: -16.5% to -4.3%), and -4.6% (95%UI: -8.1% to -0.8%), respectively. However, in some regions, the percentage changes in age-standardized rates for these indicators were greater than 0 (e.g., prevalence, mortality and DALYs in Australasia, and incidence in Andean Latin America). In China, the percentage changes in age-standardized rates of fall-related mortality and DALYs from 1990 to 2023 were -18.3% (95%UI: -56.7% to 32.3%) and 1.9% (95%UI: -10.1% to 12.4%), while the percentage changes in age-standardized rates of prevalence and incidence were 25.9% (95%UI: 20.2% to 32.0%) and 35.7% (95%UI: 28.5% to 44.1%), respectively. Globally, in regions with high and medium-to-high SDI levels, the percentage changes in age-standardized rates of fall-related prevalence and incidence showed an upward trend, while DALYs showed a downward trend; however, the trend in mortality was unclear. In regions with a middle SDI level, the percentage changes in age-standardized rates of fall-related prevalence and incidence both showed an upward trend, while the trends in mortality and DALYs were unclear. In regions with low-to-medium SDI level, the percentage changes in age-standardized rate of fall-related prevalence, DALYs and incidence all showed a downward trend, while the trend in mortality was unclear; in regions with low SDI level, the trends for all above indicators were unclear. Correlation analyses of the burden of fall-related diseases in China and globally indicated that the risk of fall-related diseases was higher among younger and middle-to-older adult male populations, while women were concentrated in older age groups. Meanwhile, as the SDI levels increase, the percentage change in age-standardized rate of DALYs for fall-related diseases showed a clear upward trend, and this trend was more pronounced in high-SDI regions. Tobacco use, alcohol consumption, low bone density, and occupational risks were risk factors for falls, with low bone density and occupational risks contributing significantly (exceeding 20% in some regions); multimorbidity and polypharmacy could also significantly increase the risk of falls. It is recommended that clinical settings establish a list of fall-risk increasing drugs and a warning system, improve medication reviews, strengthen medication education and adherence management, foster multidisciplinary collaboration, and develop medication strategies for specific patient populations to reduce the incidence of falls and alleviate the burden of disease.

The study focuses on the concept of multifunctional traditional Chinese medicine (TCM) formulas and aims to evaluate the efficacy of the classical formula Xiaoyao San (逍遥散). Study employs the integrated evidence chain (Eff-iEC) method to organize, integrate, and evaluate its therapeutic efficacy in treating different diseases with the same therapy, and to investigate the feasibility of using Eff-iEC to evaluate the multifunctionality of TCM formulas. The evaluation covered Xiaoyao San's therapeutic effects on depression, premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Concurrently, the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system was used for evaluation, and authoritative medical documents were incorporated to corroborate the recognition of Xiaoyao San within the medical community. Depression and menopausal syndrome received higher ratings than other conditions in the Eff-iEC, GRADE, and Medical Community Recognition assessments. The Eff-iEC evidence grade for Xiaoyao San was rated as "High" or above for chronic hepatitis, irritable bowel syndrome, dyspepsia, and menopausal syndrome. Premenstrual syndrome received a "Moderate +" rating. The GRADE evidence level was "Low-〇〇⨁⨁" for depression, premenstrual syndrome, and chronic hepatitis; "Moderate-〇⨁⨁⨁" for dyspepsia and menopausal syndrome; and "Very Low-〇〇〇⨁" for irritable bowel syndrome. Depression and menopausal syndrome had the highest inclusion frequency, appearing in all 4 categories. Premenstrual syndrome, chronic hepatitis, and dyspepsia are not recommended in Western medical guidelines, but they are included in TCM guidelines, the China National Basic Medical Insurance Drug List, and the China National Essential Drug List. Irritable bowel syndrome appears only in the China National Basic Medical Insurance Drug List and China National Essential Drug List. The evaluation results obtained using the Eff-iEC method align with Medical Community Recognition, providing an objective and comprehensive assessment of Xiaoyao San's efficacy. The findings suggest that Xiaoyao San has strong evidence for treating depression and menopausal syndrome. However, further experimental and clinical trials are needed to assess its efficacy in treating premenstrual syndrome, chronic hepatitis, irritable bowel syndrome, and dyspepsia. These results support the clinical efficacy and rational use of Xiaoyao San, expand the application scope of the Eff-iEC method, and offer valuable insights and methodological references for the comparative evaluation of multifunctional TCM formulas.
