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 explore the efficacy and safety of oral solution of magnesium sodium potassium sulfate in bowel preparation before colonoscopy. Methods Patients who planned to undergo colonoscopy at the digestive department of the Ninth People’s Hospital, affiliated to School of Medicine of Shanghai Jiao Tong University from January 2023 to August 2023 were selected and eligible subjects were divided into two groups: Group A took polyethylene glycol (PEG) and Group B took oral solution of magnesium sodium potassium sulfate (OSS). The quality, drug tolerance, and safety of intestinal preparation were evaluated. The quality of bowel preparation was evaluated by the boston bowel preparation scale (BBPS). Results The right colon BBPS score of Group B was (2.39±0.82) points, which was significantly higher than of Group A (2.11±0.43) points (P<0.05). The overall score of Group B was higher than that of Group A (P<0.05). OSS was easier to take than PEG, with a good taste and overall sensation. Patients were willing to use OSS to clean their bowels even when they were willing to undergo another examination (P<0.05). There was a significant difference in nausea and vomiting symptoms between the two groups (P<0.05), and there were no significant changes in renal function and electrolytes before and after medication in the two groups of patients. Conclusion OSS had a higher quality of bowel cleaning and was easier for patients to accept.

OBJECTIVE To prepare an intelligent responsive liposome-hydrogel nanopreparation co-loaded with gambogic acid (GA), and characterize its antitumor activity in vitro . METHODS GA-ICG-Lip-gel was prepared by ethanol injection and cold dissolution, incorporating GA and the photosensitizer indocyanine green (ICG). The appearance and microscopic morphology of GA-ICG-Lip-gel were observed, its encapsulation efficiency and drug loading capacity were measured, and its photothermal conversion performance, photothermal stability, and infrared imaging properties were investigated, along with the determination of its in vitro release profile. Human breast cancer MCF-7 cells were used as objects to investigate the effects of GA-ICG-Lip-gel (or with near-infrared light irradiation) on cell viability, migration ability, and the cellular uptake capacity of GA-ICG-Lip-gel. RESULTS GA-ICG-Lip-gel existed in a solution state at room temperature and transformed into a gel state at 37 ℃. Its microstructure was dense with small pores, and its encapsulation efficiency and drug loading were (96.07±0.86) % and (6.28±1.16) %, respectively. After exposure to near-infrared light, the temperature of GA-ICG-Lip-gel rose above 42 ℃, with no significant attenuation observed in the heating curve. The heating efficiency was dependent on both the irradiation time and drug concentration. Compared to media without gelatinase, the cumulative release rate of GA-ICG-Lip-gel increased in media containing gelatinase. In vitro studies showed that GA-ICG-Lip-gel could be efficiently taken up by MCF-7 cells; GA-ICG-Lip-gel significantly inhibited the viability and migration ability of MCF-7 cells ( P <0.05), and this inhibitory effect was further enhanced under near-infrared light irradiation. CONCLUSIONS This study successfully prepares GA-ICG-Lip-gel, which exhibits favorable photothermal conversion properties and temperature/enzyme dual-responsive drug release characteristics, and demonstrates significant inhibitory effects on the proliferation and migration of breast cancer cells.

ObjectiveTo investigate the therapeutic effects of the Anemarrhenae Rhizoma water extract (AR) on Alzheimer's disease (AD) model rats and to explore its potential underlying mechanisms. MethodsMale rats were intraperitoneally injected with D-galactose (100 mg·kg-1) for 42 days, and on day 14, 1 μL of β-amyloid (Aβ25-35, 2 g·L-1) solution was injected into the hippocampus. Rats were randomly divided into a model group, low-dose AR (0.6 g·kg-1), medium-dose AR (1.2 g·kg-1), high-dose AR (2.4 g·kg-1), and a positive control group (donepezil, 5 mg·kg-1). Healthy rats receiving only a hippocampal injection of 1 μL of sterile saline served as the sham-operated group. From day 21, rats in the treatment groups were administered the corresponding drugs by gavage once daily for 21 consecutive days, while the blank control and model groups received an equal volume of saline. Learning and memory abilities were assessed using the Morris water maze. Brain tissue damage was observed by hematoxylin and eosin (HE) staining, and neuronal apoptosis was evaluated by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) staining. Levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and interleukin-10 (IL-10) in brain tissues were measured by enzyme-linked immunosorbent assay (ELISA). BV2 microglial cells were co-cultured with Aβ25-35 (40 μmol·L-1) for 2 h, and cell viability was determined by the CCK-8 assay to screen the optimal concentration of AR-containing serum (S-AR). Cells were divided into blank control, Aβ25-35, S-AR, EX527 [silent information regulator 1 (SIRT1) inhibitor], and S-AR+EX527 groups. Immunofluorescence staining was used to detect the expression of CD16, CD206, and high-mobility group box 1 (HMGB1). Western blot analysis was performed to measure the protein expression of CD16, inducible nitric oxide synthase (iNOS), CD206, arginase (Arg), and proteins related to the SIRT1/HMGB1/nuclear factor-κB (NF-κB) signaling pathway. ResultsIn vivo experiments showed that, compared with the sham-operated group, the model group exhibited reduced platform crossings and time spent in the target quadrant (P<0.01), prolonged escape latency, increased hippocampal neuronal apoptosis (P<0.01), and obvious hippocampal damage. The expression levels of IL-6, TNF-α, IL-10, CD16, and iNOS in brain tissues were significantly elevated (P<0.01), while CD206 and Arg protein expression showed an increasing trend without statistical significance. Compared with the model group, all AR-treated groups significantly increased platform crossings and target quadrant time (P<0.05, P<0.01), alleviated hippocampal damage, reduced escape latency and neuronal apoptosis, downregulated the expression of TNF-α, IL-6, CD16, and iNOS (P<0.05, P<0.01), and upregulated the expression of IL-10, CD206 and Arg (P<0.05, P<0.01). In vitro experiments demonstrated that, compared with the blank control group, the Aβ25-35 group showed increased fluorescence intensity of CD206, CD16, and HMGB1, as well as elevated protein expression of iNOS and CD16 (P<0.01), while CD206 and Arg protein expression exhibited an increasing trend without statistical significance. After S-AR intervention, CD206 fluorescence intensity and the protein expression of Arg and CD206 were significantly increased (P<0.01), whereas the fluorescence intensity of CD16 and HMGB1 and the protein expression of iNOS and CD16 were significantly decreased (P<0.01). These effects were reversed by EX527 (P<0.05, P<0.01). Furthermore, compared with the blank control group, the Aβ25-35 group showed significantly increased cytoplasmic HMGB1 expression and p-p65/p65 ratio (P<0.01), along with significantly decreased SIRT1 and nuclear HMGB1 expression (P<0.01). In contrast, the S-AR group exhibited opposite trends compared with the Aβ25-35 group, and the regulatory effects of S-AR on these proteins were reversed by EX527 (P<0.01). ConclusionAR exerts neuroprotective effects in AD model rats by regulating microglial polarization and alleviating neuroinflammation, potentially through modulation of the SIRT1/HMGB1/NF-κB signaling pathway.

Fresh-cut processing constitutes a pivotal technique in the origin processing of Chinese medicinal materials, with a long history documented in multiple materia medica. In recent years, it has garnered national policy support for its ability to prevent component loss and low processing efficiency associated with traditional drying-before-cutting methods. As of August 2025, 26 provinces and municipalities nationwide have cumulatively published 789 species for fresh-cut processing. Among these, 78 were included in the 2025 edition of the Pharmacopoeia of the People's Republic of China. However, the practice continues to face common challenges and difficulties, including ambiguous scientific understanding, fragmented standards, limited quality control approaches, and poor process stability. Based on this, this paper synthesises years of research findings to systematically elucidate the core mechanisms of fresh-cut processing. These encompass alterations to herbal tissue structure during cutting, post-processing changes in constituents, and physiological-biochemical processes such as plant stress responses and shifts in endogenous enzyme activity. It also summarises influencing factors, including inherent herbal properties, cutting timing and methods, and environmental conditions like temperature, humidity, and microbial presence. Based on this overview of fresh-cutting mechanisms, subsequent research should advance in four directions:Clarifying the scientific principles of fresh-cutting, overcoming technical bottlenecks, upgrading intelligent equipment, and establishing quality standards and evaluation systems. This study provides a theoretical foundation and scientific basis for future research on fresh-cutting in traditional Chinese medicine(TCM), promoting its deeper practical application within the industry and contributing to the high-quality development of TCM industry and the modernization of TCM.

To analyze the prevalence of anemia and iron deficiency among primary and secondary school students in Rural Nutrition Improvement Program areas of Guizhou Province in 2023, and to explore the related factors, so as to provide evidence for Rural Nutrition Improvement Program optimization.
Methods:
In September 2023, a stratified random cluster sampling strategy was used to select 40 rural compulsory education schools with rural nutrition improvement program in five counties of Guizhou Province. School level questionnaire was employed to collect information of basic characteristics and school meal implementation. A total of 7 826 primary and secondary school students aged 6-16 underwent anthropometry and hemoglobin (Hb) determination; serum ferritin (SF) was additionally measured in a random subsample of 1 795 pupils. Students in Grade 3 and above also completed a questionnaire covering demographic characteristics, dietary behaviours and nutrition knowledge. Group comparisons were conducted by Chi square test or Fisher s exact test, and multivariable Logistic regression models were constructed to identify factors associated with anemia and iron deficiency.
Results:
The overall Hb level was (133.21±12.95)g/L, with an anemia prevalence of 7.17%. The overall SF level was (69.58±59.01)μg/L, with an iron deficiency prevalence of 2.73%. Multivariable analysis showed that stunting ( OR =1.88), school menus without nutrient calculation ( OR =1.61) and absence of menu planning software in the current semester ( OR =2.34) independently increased anemia risk, whereas obesity reduced it ( OR =0.54) (all P <0.05). Girls ( OR =4.16) and Grades 7-9 ( OR =5.93) increased iron deficiency risk (both P <0.05). Compared with rarely eating fresh vegetables, students with consuming <3 kinds per day ( OR =0.08) or exactly 3 kinds per day ( OR =0.06) had lower iron deficiency risks (both P <0.05).
Conclusions
Anemia and iron deficiency are prevalent among primary and secondary school students in Guizhou. Targeted intervention measures should be implemented for key populations to enhance the effectiveness of nutrition improvement program.

ObjectiveTo explore the possible mechanisms by which ligustilide (LIG) exerts neuroprotective effects on ischemic stroke (IS) by inhibiting the release of neutrophil extracellular traps (NETs), promoting blood-brain barrier repair, and alleviating post-ischemic neuroinflammation, thereby providing a new direction for IS treatment. MethodsA middle cerebral artery occlusion (MCAO) model was established in rats. The rats were divided into the sham operation (Sham) group, model (Model) group, low- and high-dose LIG groups (20, 40 mg·kg-1), and the NET inhibitor CI-amidine group (CI-amidine, 10 mg·kg-1). Drug treatments were administered for 3 days. Neurological injury after ischemia was evaluated by 2,3,5-triphenyltetrazolium chloride (TTC) staining, neurological deficit scoring, and brain index measurement. Flow cytometry and Western blot were used to analyze changes in neutrophil expression. Immunofluorescence was used to observe the fluorescence intensity of the NET marker citrullinated histone H3 (H3Cit). Western blot was performed to detect the expression of blood-brain barrier tight junction-related proteins and inflammatory factors, including interleukin-18 (IL-18) and interleukin-1β (IL-1β). ResultsCompared with the Sham group, the Model group exhibited significant brain tissue injury (P<0.05), significantly increased neutrophil numbers and NET expression (P<0.05), significantly impaired blood-brain barrier permeability (P<0.05), and significantly increased expression of inflammatory factors (P<0.05). Compared with the Model group, both low- and high-dose LIG significantly alleviated brain tissue injury in rats (P<0.01), inhibited neutrophil numbers and NET expression (P<0.01), reduced blood-brain barrier damage (P<0.01), and suppressed the expression of inflammatory factors IL-18 and IL-1β (P<0.01), thereby ultimately exerting a neuroprotective effect. ConclusionThe neuroprotective effect of LIG in rats with cerebral ischemia-reperfusion injury may be related to inhibition of neutrophils and the NETs induced by them.

AIM: To analyze the influencing factors of cognitive dysfunction in patients with open angle glaucoma, and construct a risk prediction decision tree model. METHODS:Retrospective study. The clinical data of patients with open angle glaucoma treated in the hospital from February 2022 to November 2024 were collected, and patients were divided into a cognitive dysfunction group and a cognitive function normal group according to the evaluation results of the Montreal Cognitive Assessment Scale(MoCA)at the time of admission, and the clinical data of the two groups were compared. The influencing factors of cognitive dysfunction in patients with open angle glaucoma were analyzed through Logistic regression model, and the decision tree model was analyzed and constructed based on the clinical data of the two groups through the decision tree CHAID algorithm, and the predictive performance of two models was compared using receiver operating characteristic(ROC)curves. RESULTS:The total of 179 patients with open angle glaucoma were included in this study, and were divided into a cognitive dysfunction group of 107 cases(59 males and 48 females, with 66 cases aged ≥60 y)and a cognitive function normal group of 72 cases(34 males and 38 females, with 28 cases aged ≥60 y)according to the MoCA assessment results at the time of patient admission.The incidence of cognitive dysfunction was 59.8%(107/179). The proportion of age ≥60y, education level of junior high school or below, hypertension, sleep disorders, and middle/late stage diseases in the cognitive dysfunction group were higher than those in the cognitive function normal group(all P<0.05). Logistic regression analysis showed that age ≥60 y, education level of junior high school or below, hypertension, sleep disorders, and middle/late stage disease were all risk factors for cognitive dysfunction in patients with open angle glaucoma(all P<0.05). The risk prediction decision tree model constructed using the decision tree CHAID algorithm included 4 layers and 11 nodes, and it outputed 5 risk variables: disease severity, age, sleep disorders, education level, and hypertension. Among them,the disease severity was the first layer risk variable. The ROC curve showed that the area under curve for predicting cognitive dysfunction in patients with open angle glaucoma using the risk prediction decision tree model and logistic regression model was 0.849 and 0.842 respectively, and there was no statistically significant difference in the predictive value between the two models(P>0.05). CONCLUSION: The disease severity, age, sleep disorders, education level, and hypertension are influencing factors for cognitive dysfunction in patients with open angle glaucoma, and the risk prediction decision tree model analyzed and constructed by the decision tree CHAID algorithm has good predictive value for cognitive dysfunction.

BackgroundLow medication compliance among patients with severe mental disorders increases the disease burden on both the patients' families and the society. Medication adherence is influenced by numerous factors. Traditional methods such as Logistic regression struggle to quantify the importance of these factors. By introducing Extreme Gradient Boosting (XGBoost) combined with Shapley Additive Explanations (SHAP), enables the quantification of the relative contribution weights of each factor, providing support for identifying the core influencing factors. ObjectiveTo explore the influencing factors of medication adherence among patients with severe mental disorders in Zhuhai, aiming to provide references for optimizing patient management strategies. MethodsExtract the data of patients with severe mental disorders who were registered on the mental health system platform in Zhuhai City from January 1, 2023 to March 31, 2025. A total of 9 329 patients were finally included for analysis. Influencing factors were screened using univariate analysis and multivariate logistic regression analysis, and an XGBoost model combined with the SHAP algorithm was constructed to quantify the importance of each influencing factor. ResultsAmong 9 329 patients, 8 446 demonstrated medication adherence, yielding an adherence rate of 90.53%. Multivariable analysis identified several risk factors significantly associated with medication non-adherence, being unmarried (OR=1.237, 95% CI: 1.019–1.502) or divorced (OR=1.389, 95% CI: 1.038–1.832), a diagnosis of mental retardation with psychiatric disorders (OR=3.025, 95% CI: 2.402–3.796) or paranoid psychosis (OR=5.117, 95% CI: 3.086–8.299), a disease duration of 2–4 years (OR=1.355, 95% CI: 1.085–1.696), 4–6 years (OR=2.143, 95% CI: 1.671–2.747), or >6 years (OR=1.681, 95% CI: 1.365–2.079), lack of guardian subsidies (OR=1.412, 95% CI: 1.099–1.801), absence of a disability certificate (OR=1.900, 95% CI: 1.588–2.282), not being enrolled in care and support groups (OR=1.384, 95% CI: 1.183–1.617) or community services (OR=1.313, 95% CI: 1.042–1.645), and not cohabiting with a guardian (OR=1.257, 95% CI: 1.048–1.501). Conversely, the enrollment in special outpatient disease programs (OR=0.716, 95% CI: 0.609–0.842) and a family history of mental illness (OR=0.713, 95% CI: 0.503–0.982) were identified as protective factors. The XGBoost model exhibited robust predictive performance, with a sensitivity of 0.433, specificity of 0.944, accuracy of 0.891, Area Under the Curve (AUC) of 0.837, and F1 value of 0.449. Feature importance ranking indicated that the top three factors were disease duration, diagnosis, and the acquisition of disability certificates. ConclusionPolicy-based support (acquisition of disability certificates, special outpatient disease enrollment) and clinical disease characteristics (disease duration, diagnosis type) are key factors affecting medication adherence among patients with severe mental disorders in Zhuhai City.
