Objective To establish a highly efficient and sensitive technical system for the identification and analysis of platycodin-type saponins, systematically compare the differences in platycodin-type saponins among Platycodon grandiflorum from different producing areas, and provide scientific references for the screening of high-quality Platycodon grandiflorum resources, authenticity evaluation, and construction of standardized quality control systems. Methods A total of 45 batches of P. grandiflorum medicinal materials from 3 producing areas (Anhui, Henan, and Jilin, with 15 batches per area) were selected as research objects. Qualitative identification and semi-quantitative analysis of saponin components were performed based on ultra-high performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry (UHPLC-Q-TOF/MS) technology. Meanwhile, two multivariate statistical methods, principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA), were combined to analyze the differences in platycodin-type saponins of Platycodon grandiflorus from different producing areas. Results A total of 28 saponin components were identified from Platycodon grandiflorus of the three producing areas. PCA results showed that there were minor differences in platycodin-type saponins between Henan Platycodon grandiflorus and Jilin Platycodon grandiflorus, while Anhui P. grandiflorum exhibited significant differences from both. PLS-DA further screened 15 major differential compounds. Among them, the contents of 6 components including 3''-O-acetylpolygalacin D2 and platycodin H in Anhui Platycodon grandiflorus were higher than those in Henan and Jilin Platycodon grandiflorus; platycodigenic acid A had the highest content in Jilin Platycodon grandiflorus; the contents of platycodin D3, polygalacin J, and polygalacin D were relatively higher in Henan Platycodon grandiflorus. Conclusion This study clarified the characteristic differences in core components of Platycodon grandiflorus from the three major producing areas, which provided an important theoretical basis for the screening of high-quality Platycodon grandiflorus resources, elucidation of the mechanism underlying its authenticity, and construction of a standardized quality control system.

OBJECTIVE To investigate the neuroprotective effect and mechanism of eleutheroside B (ELB) on Parkinson’s disease (PD) model mice by regulating the IκB kinase β (IKKβ)/nuclear factor-κB (NF-κB) signaling pathway. METHODS Fifty mice were randomly divided into normal control group, model group, positive control group (selegiline hydrochloride, 10 mg/kg), and ELB low-dose and high-dose groups (80, 160 mg/kg), with 10 mice in each group. Each group was given relevant medicine or normal saline intragastrically for 14 consecutive days. Starting from the 10th day of administration, the model group and all administration groups were intraperitoneally injected with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) 30 mg/kg, for five consecutive days to establish the chronic PD model. After the last administration for 24 h, six mice were randomly selected from each group to test their behavioral abilities; detect the levels of interleukin-1β (IL-1β), IL-10, tumor necrosis factor-α (TNF-α) in brain tissue and their mRNA expressions were measured, and positive expression of tyrosine hydroxylase (TH), protein expressions of TH, α -synuclein ( α -syn), ionized calcium-binding adaptor molecule 1 (Iba-1), as well as phosphorylation levels of IKKβ and NF-κB p65 proteins in the brain tissue were detected. The ultrastructure of neurons in substantia nigra was observed. RESULTS Compared with the model group, rotarod endurance time and climbing score of each administration group (except for the ELB low-dose group) were increased significantly ( P <0.05), while the levels and mRNA expressions of IL-1β, TNF-α, α -syn, and Iba-1, as well as phosphorylation levels of IKKβ and NF-κB p65 proteins in brain tissue were decreased significantly (except for TNF-α in the ELB low-dose group). Conversely, the level and mRNA expression of IL-10 (except for the ELB low-dose group), TH positive expression and protein expressions were significantly increased ( P <0.05). Typical neurodegenerative pathological changes, such as neuronal karyopyknosis, mitochondrial swelling and vacuolization, and endoplasmic reticulum dilation, all showed varying degrees of improvement. CONCLUSIONS ELB may exert neuroprotective effects by inhibiting the activation of the IKKβ/NF-κB signaling pathway, alleviating inflammatory responses, reducing abnormal α -syn aggregation and neuronal loss, and further improving motor dysfunction in PD mice.

Objective:
To review the relationship between 24 hour movement behaviors and physical and mental health among college students, in order to provide evidence to support health promotion and further research in universities.
Methods:
Following the Joanna Briggs Institude(JBI) scoping review guidelines, relevant studies published in databases from inception date to December 26, 2025 were searched, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data. For studies meeting the inclusion and exclusion criteria, a descriptive analysis was conducted to summarize the measurement tools used, adherence rates with guidelines, and the relationship between physical and mental health.
Results:
A total of 30 studies were included. Measurement tools exhibited a high heterogeneity, with questionnaires being the primary method. The rate of full adherence with 24 hour movement behaviors among college students was less than 30%. Moderate to vigorous physical activity and high quality sleep were associated with improvements in physical fitness, cardiopulmonary function, and mental health, while prolonged sitting was negatively associated with obesity and depression. Equivalent time substitution analysis indicated that increasing moderate to vigorous physical activity and reducing prolonged sitting could significantly improve health outcomes.
Conclusions
The adherence rate for 24 hour movement behaviors among college students is low and it is closely associated with physical and mental health. Future studies should standardize measurement tools, and implement targeted interventions based on the optimization of daily activity patterns.

BackgroundArrhythmia and obsessive-compulsive disorder (OCD) frequently co-occur in clinical and epidemiological settings, yet their shared genetic basis and potential heart-brain axis mechanisms remain unclear. ObjectiveTo systematically evaluate the genetic correlation between arrhythmia and OCD, and to elucidate their underlying molecular genetic mechanisms, so as to provide molecular evidence for the "heart-brain axis" to support risk assessment and integrated clinical strategies for these comorbidities. MethodsThe aggregated data from the genome-wide association study (GWAS) of arrhythmia in the UK Biobank (7 207 cases and 477 391 controls) and the GWAS data of OCD released by the Psychiatric Genomics Consortium (2 688 cases and 7 037 controls) were integrated, all of which were limited to individuals of European ancestry. The genome-wide genetic correlations were estimated using the linkage disequilibrium score regression (LDSC) and the high-definition likelihood (HDL). Local genetic correlation analysis was conducted using the local analysis of variance annotation (LAVA). Multi-trait analysis of GWAS (MTAG) was employed to identify pleiotropic loci. Shared risk genes were identified by combining summary-data based Mendelian randomization (SMR) and transcriptome-wide association study (TWAS). Functional enrichment analysis was performed based on the functional mapping and annotation (FUMA) platform. ResultsBoth LDSC (rg=0.248, 95% CI: 0.159–0.336, P=4.82×10-3) and HDL (rg=0.294, 95% CI: 0.237–0.351, P=5.87×10-4) revealed significant positive genetic correlation between arrhythmia and OCD. LAVA identified 23 significantly local correlated regions in the genome (P<2.0×10-5). MTAG discovered 11 genome-wide significant pleiotropic SNPs, among which rs12754189 (intron of KCNN3) had potential functional harmfulness (CADD>12.37). SMR and TWAS jointly identified 20 shared genes, enriched in neural-cardiovascular tissues such as the cerebral cortex, amygdala, and left ventricle, and involved in DNA damage response, RNA metabolism, transcriptional regulation, and FAS signaling pathway (FDR<0.05). ConclusionArrhythmia and OCD share a common genetic basis. The co-morbidity mechanism may involve the common vulnerability of neurons and cardiac muscle cells in terms of gene expression regulation and stress response, supporting the role of the brain-heart axis in the pathophysiology of both conditions.

Introduction:
Improving glycemic control while minimizing unnecessary
insulin exposure is an important goal in diabetes
management. The Rapid Optimization Clinic (ROC) was
established as a structured multidisciplinary service to
support therapy individualization, close follow-up, and
timely insulin deintensification. This audit evaluated early
changes in glycated hemoglobin A1c (HbA1c) and insulin
treatment burden following ROC care over 3 months.
Methodology:
We conducted a retrospective audit of routine clinical
data from patients with diabetes managed in the ROC at a
district hospital. Baseline and 3-month HbA1c and insulin
data were extracted from non-electronic clinic records.
Insulin dose was standardized as total daily dose (TDD)
in units/kg/day. Insulin deintensification was evaluated
primarily by change in TDD from baseline to 3 months and
by the proportion of patients who discontinued insulin
during follow-up. Paired analyses were performed for patients with complete baseline and follow-up data for
each outcome. Continuous variables are presented as mean
± standard deviation or median with interquartile range,
as appropriate. Exploratory analyses were undertaken to
assess whether available patient factors were associated
with HbA1c improvement.
Results:
Twenty-three patients were included. Paired HbA1c data
were available for 12 patients, whereas paired TDD data
were available for 21 patients. Mean HbA1c decreased
from 10.78 ± 2.59% at baseline to 8.42 ± 2.29% at 3 months,
representing a mean reduction of 2.36 percentage points
(95% confidence interval [CI] 0.09–4.62; p = 0.043). Mean TDD
decreased from 0.434 ± 0.248 to 0.286 ± 0.313 units/kg/day,
corresponding to a mean reduction of 0.148 units/kg/day
(95% CI 0.077–0.219; p <0.001). Insulin was discontinued in
9 of 21 patients (42.9%). No clear association was observed
between HbA1c improvement and age, sex, or number of
visits. Interpretation is limited by the small sample size,
reflecting the early phase of a newly established clinic.
Conclusion
In this early audit, ROC care was associated with clinically
meaningful improvement in glycemic control and
significant insulin deintensification over 3 months. These
findings support the potential role of a structured multidisciplinary optimization clinic in delivering individualized
diabetes care and facilitating safe reduction of insulin
burden.

Idiopathic pulmonary fibrosis (IPF) can be classified as pulmonary collateral disease,and its pathogenesis is mainly characterized by the loss of Qi meridian nourishment,the loss of Yin meridian nourishment,and the formation of blood stasis in the blood vessels. Qi Yin deficiency is the pathological basis that runs through IPF,and obstruction of meridians and collaterals is a key element in the development of the disease. The dysfunction of "spleen being in charge of the defensive function" is closely related to the formation of the pathological pattern of "lung deficiency and collateral stasis" in IPF. The term "spleen being in charge of the defensive function" originated from the Yellow Emperor's Inner Canon. If the spleen is healthy,the Qi will be filled with vitality. Positive energy is stored inside,evil cannot be dried up. Its concept is quite similar to the immune defense function in modern medicine. If the principle of "spleen being in charge of the defensive function" is lost,the key structure and function of the IPF alveolar epithelial barrier may be abnormal,and it can interact with various innate immune cells to promote inflammation and fibrosis processes. Therefore,this article explains the imbalance of immune homeostasis in IPF alveolar epithelium from two aspects:the barrier function of alveolar epithelial cells(AECs) and their interaction with innate immune cells. And based on the theory of "spleen being in charge of the defensive function",using traditional Chinese medicine for strengthening the spleen and nourishing Qi to treat IPF from the perspective of the spleen. This not only strengthens the scientific connotation of "spleen being in charge of the defensive function" in the pathogenesis of IPF,but also provides new research directions and ideas for its future clinical prevention and treatment.

Objective To observe changes in genetic material in the peripheral blood of pediatric patients with vascular malformations after interventional procedures. Methods A total of 108 children with vascular malformations who underwent interventional procedures at Shandong University Affiliated Children’s Hospital between February 2021 and January 2024 were selected as the research subjects. Clinical data and peripheral venous blood samples before and after the interventional procedures were collected from the children. Two biological indicators, γ-H2AX and peripheral blood lymphocyte chromosomal aberration (CA), were used to determine the levels of genetic material damage in children with vascular malformations before and after interventional procedures. Results The median age of the children was 7 years and the median body weight was 27 kg. The median dose-area product (DAP) was 24.20 Gy·cm2 and the median DAP/kg was 1.04 Gy·cm2/kg. The incidence rates of both γ-H2AX foci and CA in children with vascular malformations significantly increased after the interventional procedures (Z = 5.924, P < 0.001; Z = 8.515, P < 0.001). The incidence of postoperative CA in 7 children were significantly higher than that in others, approaching or exceeding 4%. The incidence rates of postoperative γ-H2AX foci and CA in children with DAP/kg ≥ 1 Gy·cm2/kg were significantly higher than those in children with DAP/kg < 1 Gy·cm2/kg (U = 7.586, P = 0.031; U = 6.835, P = 0.009). No significant differences were observed in the incidence rates of postoperative γ-H2AX foci and CA among subgroups based on age, body weight, or surgical site. A positive correlation was observed between the difference in the incidence rates of γ-H2AX foci before and after the procedure and DAP/kg (R = 0.493, P = 0.027). Conclusion Ionizing radiation exposure during interventional procedures can increase peripheral blood genetic material damage levels in children with vascular malformations, and the damage levels show a correlation with the radiation dose, with some children being abnormally sensitive. Further research is needed to explore the influencing factors for genetic material damage in children with vascular malformations after interventional procedures, which is of great significance for reducing long-term cancer risks and achieving personalized treatment strategies.

Shanghai Journal of Preventive Medicine 2025;37(3):234-238
ObjectiveTo analyze the safety of simultaneous vaccination of 13-valent pneumococcal conjugate vaccine (PCV13) and oral pentavalent human rotavirus live attenuated vaccine (RV5) in age-eligible children in Changning District, Shanghai. MethodsAdverse events following immunization (AEFI) and vaccination information after PCV13 and RV5 vaccination from Jan.1, 2022 to Dec.31, 2023 were collected through the National Immunization Program Information Management System and the Shanghai Immunization Information System in Changning District. We compared the incidence rates of AEFI reports after PCV13 and RV5 standalone and simultaneous vaccination. ResultsPCV13 was administered standalone in 7 654 doses, with 107 AEFI reports and an AEFI reporting rate of 1 397.96/100 000, including 1 371.83/100 000 for general reactions (105 cases) and 26.13/100 000 for abnormal reactions (2 cases). RV5 was administered standalone in 8 114 doses, with 30 AEFI reports and an AEFI reporting rate of 369.73/100 000, all of which were general reactions. PCV13 and RV5 were administered simultaneously in 6 731 doses, with 56 AEFI reports and an AEFI reporting rate of 831.97/100 000, including 802.26/100 000 for general reactions (54 cases), 14.86/100 000 for abnormal reactions (1 case), and 14.86/100 000 for coupling symptoms (1 case). ConclusionThe incidence rates of AEFI reports after PCV13 and RV5 vaccination standalone or simultaneous among age-eligible children in Changning District are within an acceptable range, primarily consisting of general reactions. PCV13 and RV5 simultaneous vaccination did not increase the risk of AEFI incidence.

Objective:To investigate the level of urinary serine protease(Corin) in early diabetic kidney disease(DKD) and its correlation with clinical stage.Methods:One hundred and seventy-three patients with type 2 diabetes mellitus(DM) from two tertiary A hospitals in Henan, diagnosed between April 2023 and December 2023 were selected as the research group, and 120 healthy subjects were selected as the control group. Basic clinical information and laboratory data were collected, and urinary Corin level was detected. DM patients were classified into G1-G5 stages based on estimated glomerular filtration rate(eGFR), and those in the early DKD stages(G1-G3) were further divided into A1-A3 subgroups based on urinary albumin/creatinine ratio(ACR). Spearman correlation analysis was performed to assess relationships between urinary Corin and other indicators, linear regression analysis identified factors influencing urinary Corin in early DKD patients, logistic regression analysis evaluated the risk factors for early DKD, and receiver operating characteristic(ROC) curve analysis determined the diagnostic value of urinary Corin in early DKD. Results:Urinary Corin levels were significantly higher in early DKD patients compared to healthy controls, with levels increasing as ACR rose( P<0.05). Urinary Corin was positively associated with serum creatinine( r=0.570), urea( r=0.458), cystatin C( r=0.693), ACR( r=0.616), urinary transferrin( r=0.448), urinary α1 microglobulin( r=0.507), urinary n-acetyl-β-D-glucosaminase( r=0.388) and A subgroup( r=0.692) while was negatively correlated with eGFR( r=-0.647), albumin( r=-0.312)(all P<0.05). eGFR was the only independent factor affecting urinary Corin. After adjusting for confounding factors in logistic regression analysis, urinary Corin was still an independent influencing factor for early DKD. ROC curve analysis indicated that urinary Corin had a diagnostic AUC of 0.842(95% CI 0.791-0.892, P<0.001), with a cut-off value of 2 226.04 pg/mL, sensitivity of 0.712, and specificity of 0.858 for early DKD diagnosis. Conclusions:Urinary Corin was elevated in early DKD patients and correlated with clinical stage. Urinary Corin is an independent factor of early DKD, and a reliable predictor of early DKD diagnosis.
