[Objective] To investigate the antigen and gene frequency distribution of the MNS blood group system in the Han population of voluntary blood donors in Suzhou, and to explore the polymorphism of rare MNS blood group genes, in order to improve the construction of the local rare blood group database. [Methods] A total of 8 034 whole blood samples were randomly collected from Han blood donors at our station from October 2023 to June 2024. The MNS blood group phenotypes were identified using serological methods. Gene frequencies were analyzed and compared with those of ethnic populations in other regions. Rare MNS phenotype samples were subjected to gene sequencing. [Results] The distribution of MNS blood group system phenotypes within the population was as follows: the MM, NN, and MN phenotypes accounted for 23.00%, 27.12%, and 49.88% respectively; the SS, ss, and Ss phenotypes accounted for 0.30%, 90.99%, and 8.70% respectively. The gene frequencies of M, N, S, and s were 0.4794, 0.5206, 0.0465, and 0.9534 respectively. Chi-squared tests confirmed adherence to Hardy-Weinberg equilibrium with P-values of 0.997 and 0.349, showing statistical significance compared to some other regional ethnic populations (P<0.05). Additionally, one rare serological phenotype, S-s-, with a frequency of 0.01%, was identified. [Conclusion] The MNS blood group system in the Han population of voluntary blood donors in Suzhou exhibits polymorphism and regional distribution characteristics. Gene frequencies differ from those observed in other regions of China. It is essential to enhance the establishment of a rare blood type database in Suzhou to provide data support for precise clinical transfusion.

Objective:
To analyze the association and dose response relationship between physical activity and inflammatory markers in college students, so as to provide a reference for promoting cardiometabolic health in college students.
Methods:
A cluster random sampling method was used to select 747 college students from two universities in Hefei, Anhui Province and Shangrao, Jiangxi Province from April to May 2019. Physical activity was assessed by using the International Physical Activity Questionnaire-Short Form (IPAQ-SF), and peripheral blood was collected to detect plasma inflammatory factor levels [including hypersensitive C reactive protein (hsCRP), interleukin-10 (IL-10), interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)]. The differences between the groups were compared by using the χ 2 test and the Kruskal-Wallis rank sum test, and the association between physical activity and inflammatory markers was analyzed by using the Generalized Linear Model. The dose response relationship between physical activity and inflammatory markers was analyzed using the Restricted Cubic Spline Model.
Results:
The proportions of low physical activity, moderate physical activity, and high physical activity groups of college students were 15.9%, 53.7% and 30.4%, respectively. The levels of hsCRP, IL-10, IL-1β, IL-6 and TNF-α in the high physical activity group were 0.38(0.21, 1.10)mg/L, 70.74(47.90, 116.43)pg/mL, 1.75(1.21, 2.64)pg/mL, 4.33(2.93, 6.82) pg/mL , 5.27(3.89, 7.30)pg/mL,the levels in the low physical activity group were 0.80(0.31, 1.30)mg/L, 73.88 (47.90, 124.24)pg/mL, 1.88(1.42, 2.81) pg/mL, 4.82 (3.64, 6.67) pg/mL, 5.63 (4.34, 7.62)pg/mL, the levels in the moderate physical activity group were 0.63(0.25, 1.30)mg/L, 89.78(58.21, 127.65)pg/mL, 2.21(1.59, 3.27)pg/mL, 5.15( 3.72 , 7.72)pg/mL, 5.87( 4.63 , 8.00)g/mL, and the differences were statistically significant ( H=10.66, 11.38, 27.79, 14.13, 9.44, P <0.05). After adjusting for variables such as gender, body mass index, smoking, alcohol consumption and health status, the results of Generalized Linear Model showed that compared with the high physical activity group, the low physical activity group ( OR=2.20, 95%CI = 1.46- 3.31) and the moderate physical activity group ( OR=1.65, 95%CI =1.22-2.25) were more likely to have high levels of hsCRP, and the moderate physical activity group was more likely to have high levels of IL-1β ( OR=1.85, 95%CI =1.36-2.51), IL-6 ( OR=1.44, 95%CI =1.06-1.96), and TNF-α ( OR=1.43, 95%CI =1.05-1.94) ( P <0.05). The Restricted Cubic Spline Model showed that there was no linear dose response relationship between the time of moderate to vigorous physical activity weekly and IL-10, IL-6, II-1β, and TNF-α ( P <0.05).
Conclusion
There is an association between physical activity and inflammation in college students, and moderate to high intensity per week could reduce inflammation levels to promote cardiometabolic health in college students.

OBJECTIVE To provide a reference for optimizing and promoting the quality standards of Shechuan naolitong granules. METHODS Fifteen batches of Shechuan naolitong granules were used as samples to establish HPLC fingerprints using the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012 edition). Similarity evaluation and common peak identification were performed, and orthogonal partial least squares discriminant analysis (OPLS-DA) was used to assess quality differences among different batches and to screen quality differential components. Using salvianolic acid B(SAB) as the internal reference, quantitative analysis of multi-components by single-marker (QAMS) was developed to simultaneously determine geniposidic acid (GA), chlorogenic acid (CA), vaccarin (VA), ferulic acid (FA) and senkyunolide I (SI). The results were compared with those obtained by the external standard method. RESULTS A total of 13 common peaks were identified in the HPLC fingerprints of 15 batches of samples, and the similarities of the spectra were all above 0.96. Seven chromatographic peaks were identified as GA (peak 3), CA (peak 6), VA (peak 8), FA (peak 9), SI (peak 11), SAB(peak 12) and TA(peak 13). OPLS-DA indicated that the differential quality markers among 15 batches were peaks 5, 11 (SI), and 12 (SAB).Using SAB as the internal reference, the relative correction factors for GA, CA, VA, FA and SI were calculated as 1.058 4, 0.594 3, 0.643 3, 0.342 7 and 0.262 8, respectively. The mean content of GA, CA, VA, FA, SI and SAB across the 15 batches of samples were 0.155 0, 0.085 4, 0.140 3, 0.071 8, 0.072 7, 1.276 3 mg/g, respectively, showing no significant difference compared with the ESM (P>0.05). CONCLUSIONS The established HPLC fingerprint and QAMS are simple, efficient and economical, providing a reference for the quality control and further development of Shechuan naolitong granules.

Objective To construct a predictive model for cerebral small vessel disease (CSVD) MRI burden based on β2-microglobulin (β2-MG) and lipoprotein(a) [Lp(a)], analyze its predictive value, and validate the model. Methods A total of 138 CSVD patients admitted to Anhui No.2 Provincial People’s Hospital from February 2023 to August 2024 were enrolled. Patients were divided into a low-burden group (n=63) and a moderate/severe burden group (n=75) according to the CSVD MRI burden scoring criteria. The related clinical data were compared between the two groups. Binary logistic regression analysis was used to identify independent factors for CSVD moderate/severe MRI burden. A nomogram predictive model was constructed based on these factors and its performance was evaluated. Results The proportions of male patients, as well as those with a history of diabetes or hypertension, were significantly higher in the moderate/severe burden group than those in the low burden group. Additionally, the age of patients in the moderate/severe burden group was significantly older, and the levels of β2-MG, Lp(a), and homocysteine (Hcy) were higher than those in the low burden group (P<0.01). Binary logistic regression analysis revealed that hypertension, diabetes, β2-MG, and Lp(a) were independent factors for CSVD moderate/severe MRI burden (P<0.05). The nomogram predictive model based on these four factors had a cut-off value of 0.467 0, with an area under curve (AUC) of 0.838 7 (95%CI 0.760 8-0.916 6) in the training set (n=97) and 0.854 1 (95%CI 0.742 1-0.966 1) in the internal validation set (n=41) . The calibration curve demonstrated good agreement between predicted and observed values. Decision curve analysis (DCA) indicated that the nomogram model had good clinical utility. Conclusions The nomogram model based on β2-MG and Lp(a) has high predictive performance in assessing the risk of CSVD moderate/severe MRI burden, with good discrimination and calibration.

To analyze the treatment strategy for a 78-year-old female patient with mismatch repair deficient (dMMR) gastric cancer who achieved long-term survival. After third-line chemotherapy failed, gene testing showed ARID1A p.Gln748fs, c.2733-1G>T variation, with PD-L1 TPS 30%, CPS 60%. The nivolumab was employed, and two weeks later, the best response was partial response (PR). During the fourth-line immunotherapy maintenance treatment, progression of left adrenal metastasis was observed. The expression of human epidermal growth factor receptor-2 (HER-2) was positive, and the antibody drug conjugate disitamab vedotin (RC48) was chosen for treatment. After 10 months of treatment with nivolumab combined with RC48, the best efficacy was assessed as stable disease (SD), with a progression free survival (PFS) of up to 12 months. Radiotherapy was employed, and immunotherapy was maintained, allowing the patient to achieve a PFS of 18 months again. During immunotherapy, a clinical pharmacist developed a personalized pharmaceutical care plan for this patient. At the last follow-up, this patient achieved 78 months of long-term survival.

Objective:
With the development of global nuclear power, the discharge of tritium during nuclear power plant
operation has raised concerns. This study provides basic data support for the assessment of tritium radioactivity levels in sea-water and seafood around nuclear power plants.
Methods:
This study selected the coastal waters near a nuclear power plant
in China as the research area. A total of 15 surface seawater samples and three types of marine organisms (laver, oyster, and
mullet) were collected to measure and analyze the tritium activity concentrations in seawater and marine organisms.
Results:
The tritium activity concentrations in seawater ranged from 1.54 to 3.55 Bq/L, with an average of 2.25 ± 0.70 Bq/L.In marine organisms, the tritium activity concentrations ranged from 1.1 to 1.6 Bq/L. The total dose rates of tritium to mullet and oyster were 6.93 × 10−7 μGy/h and 5.39 × 10−7 μGy/h, respectively.
Conclusion
Compared with tritium activity concentrations in adjacent waters, those in seawater near this nuclear power plant showed no significant increases, and the tritium content in marine organisms remained within normal ranges. The radiation doses of tritium in mullet and oyster did not pose a radiation hazard to these two organisms.

OBJECTIVE To evaluate the long-term cost-effectiveness of insulin degludec and insulin aspart (IDegAsp) in patients with type 2 diabetes mellitus (T2DM) in China. METHODS A cost-effectiveness analysis was conducted from the perspective of the Chinese healthcare system, using the CORE diabetes model to simulate long-term (20-year) health and economic outcomes. Baseline cohort characteristics and treatment effect data were derived from the CREATE study. The prices of glucose- lowering drugs were obtained from medical insurance payment standards and the average winning bid prices in the follow-up round of the specialized centralized procurement for insulin, while the daily dosages were derived from the CREATE study. The costs of complications and utility values were obtained from published literature, with a discount rate of 5%. One-way sensitivity analysis, scenario analysis, and probabilistic sensitivity analysis were performed to verify the robustness of the results. RESULTS Patients switching from previous once-daily basal insulin regimens to IDegAsp therapy gained an incremental 0.190 quality-adjusted life year (QALY) with direct medical cost savings of 42 163.58 yuan. For those switching from premixed insulin therapies, IDegAsp treatment provided 0.130 incremental QALY and reduced direct healthcare costs by 41 129.11 yuan. The outcome was significantly influenced by the discount rate and the cost of complications. Probabilistic sensitivity analysis and scenario analysis confirmed the robustness of these findings. CONCLUSIONS Switching from previous daily basal insulin or premixed insulin regimens to IDegAsp in Chinese patients with T2DM can improve patients’ long-term health outcomes and achieve cost savings, making it a more cost-effective treatment option.

OBJECTIVE To comprehensively evaluate the efficacy, safety and cost-effectiveness of insulin icodec in treating type 2 diabetes mellitus (T2DM), providing evidence-based guidance for new drug selection in hospital and clinical medication decision-making. METHODS PubMed, Cochrane Library, Embase, CNKI, Wanfang, VIP and foreign health technology assessment (HTA) websites were searched by using rapid health technology assessment from inception to 15 July 2025 for systematic reviews/meta-analyses, pharmacoeconomic studies, and HTA reports on insulin icodec in the treatment of T2DM. After data extraction and quality assessment, the findings of the included studies were analyzed descriptively. RESULTS Ten systematic reviews/meta-analyses and three pharmacoeconomic studies were included. Among them, 4 systematic reviews/meta-analyses were of high quality; the overall quality of the 3 pharmacoeconomic studies was relatively good. Regarding efficacy, insulin icodec was superior to once-daily basal insulin in reducing glycated hemoglobin (HbA1c) and in achieving the target of HbA1c<7% (P<0.05). No significant differences were observed between icodec insulin and comparators in lowering fasting plasma glucose (P>0.05). For safety, insulin icodec did not increase the incidence of any adverse events (AEs), serious AEs, clinically significant hypoglycemia (random glucose<3 mmol/L), injection-site reactions, or allergic reactions, compared with once-daily basal insulin overall (P> 0.05); however, insulin icodec was associated with a significant increase in body weight (P<0.05). Domestic economic evaluations indicated that insulin icodec was more cost-effective than insulin glargine and insulin degludec when its annual costs were in the range of 784.90-1 145.96 and 597.66-736.34 US dollars, respectively. CONCLUSIONS Insulin icodec demonstrates favorable efficacy and safety profiles in the treatment of T2DM; however, attention should be paid to the risk of weight gain. Under China’s healthcare system, insulin icodec demonstrates greater economic value only when the patient’s weekly required basal insulin dose falls within a specific range,and clinical practice requires individualization.

objectiveTo investigate the differences in clinical indices and lipid metabolism between the patients with nonalcoholic fatty liver disease (NAFLD) and healthy individuals in the overweight population. MethodsIn this study, body mass index (BMI)>23 kg/m2 was defined as overweight. A total of 62 overweight patients with NAFLD who were admitted to Putuo Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from August 2020 to April 2021 were enrolled as overweight NAFLD group, and 50 overweight individuals who underwent physical examination during the same period of time were enrolled as control group. Clinical information and blood biochemical parameters were recorded for all subjects. Ultra-performance liquid chromatography-tandem mass spectrometry was used to analyze serum lipidomic profile, and principal component analysis and orthogonal partial least squares-discriminant analysis were used to perform the multivariate statistical analysis of lipidomic data. The chi-square test was used for comparison of categorical data between two groups, and the independent-samples t test or the Wilcoxon rank-sum test was used for comparison of continuous data between two groups. ResultsThe overweight NAFLD group had a significantly higher BMI than the overweight control group (Z=-2.365, P=0.018). As for serological markers, compared with the overweight control group, the overweight NAFLD group had significantly higher levels of red blood cells, hemoglobin, hematocrit, uric acid, total protein, globulin, alkaline phosphatase, gamma-glutamyl transpeptidase, alanine aminotransferase, aspartate aminotransferase, cholinesterase, low-density lipoprotein, total cholesterol, triglyceride, apolipoprotein B, and blood glucose (all P<0.05). The lipidomic analysis showed that there was a significant difference in lipid metabolism between the two groups, and a total of 493 differentially expressed lipids were identified (VIP value>1, P<0.05), among which 143 lipids were significantly upregulated and 350 lipids were significantly downregulated in the overweight NAFLD group. The mean total fatty acid content in the overweight NAFLD group was 3.6 times that in the overweight control group. Compared with the overweight control group, the overweight NAFLD group had a significant reduction in the content of triglyceride with>3 unsaturated bonds (P<0.001) and a significant increase in the content of triglyceride with ≤3 unsaturated bonds (P<0.001). ConclusionCompared with healthy overweight individuals, overweight NAFLD patients tend to have significant abnormalities in some biochemical parameters and lipid metabolites, with significant increases in the content of fatty acid in blood and the types of saturated fat chains in triglycerides.
