Objective: To investigate the incidence, characteristics, and influencing factors of resolution discrepancies within the minipool (MP) testing model across Chinese blood station laboratories in 2024. Methods: A nationwide, multicenter, cross-sectional study was conducted, including 334 blood station laboratories that reported nucleic acid reactive data among enzyme immunoassay non-reactive samples. Of these, 296 laboratories adopted the pool resolution model, with a total of 12 536 273 samples tested. Systematic analysis was performed on resolution data, focusing on the MP-NAT reactivity rate, the pool resolution concordance rate, and the resolution discrepancy rate. Subgroup analyses were conducted based on reagent types, viral targets, and Ct values. Potential causes were further explored through laboratory surveys and re-examination of raw amplification curves. Results: In 2024, the national average MP-NAT reactivity rate was 0.15%. The overall pool resolution concordance rate was 57.86%, which showed a gradual decline as Ct values increased across all reagents. The national average resolution discrepancy rate was 0.081‱(102/12 536 273), with 17.91%(53/296) of laboratories reporting at least one discrepancy. Nine reagent types were associated with these events, exhibiting reagent-specific patterns. For Reagent A2, the predominant discrepancy was HBV reactive pools resolving as HIV (36.36%); for Reagent D1, HBV pools frequently resolved as HCV (38.89%); and for Reagent E, the most common pattern was HIV pools resolving as HBV (48.00%). These resolution discrepancies were strongly associated with high Ct values: the median pool Ct for HBV exceeded 38, while those for HCV and HIV both exceeded 40. Investigations across 16 laboratories revealed that most discrepant samples exhibited “tailing” amplification curves, with some cases linked to cross-contamination or reagent batch-specific issues. Conclusion: While the incidence of resolution discrepancies in the MP-NAT model remains low in China, variations exist across different reagents and laboratories. These discrepancies are closely associated with low viral load, reagent performance, and laboratory operational practices.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance, while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine (TCM) has a long history in the prevention and management of this condition, demonstrating eight distinct advantages, including systematic theoretical foundation, diversified therapeutic approaches, definite therapeutic efficacy, high safety profile, good patient compliance, comprehensive intervention strategies, emphasis on prevention, and stepwise treatment protocols. Additionally, TCM is characterized by six distinctive features: the use of natural medicinal substances, non-invasive external therapies, integration of medicinal dietetics, simple exercise regimens, precise syndrome differentiation, and diverse dosage forms. By combining internal and external treatments, TCM facilitates individualized regimen adjustment and holistic regulation, demonstrating remarkable effects in improving obesity-related metabolic indicators, regulating constitutional imbalance, and promoting healthy behaviors. However, challenges remain, such as inconsistent operational standards, insufficient high-quality clinical evidence, and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment, conducting multicenter randomized controlled trials, and fostering interdisciplinary integration, so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Sonodynamic therapy (SDT) applies low-frequency ultrasound to activate sonosensitizers that have accumulated in tumor location, which induces cavitation effects and leads to the in-situ generation of reactive oxygen species (ROS), thereby achieving precise and efficient tumor treatment. Owing to its advantages such as deep tissue penetration and controllable treatment range, SDT has attracted significant attention and has been widely used in the research on the treatment of various tumors. While conventional treatment modalities have achieved significant efficacy in the treatment of hepatocellular carcinoma (HCC), there are still certain limitations. In this context, nanomedicine-based SDT leverages the targeting capabilities of nano-agents to realize specific killing of HCC cells, and furthermore, it can synergize with photodynamic therapy, chemotherapy, and immunotherapy to provide new opportunities for developing novel treatment modalities for HCC. This article reviews the mechanism of action of SDT and the advances in the research and application of SDT in the treatment of HCC, analyzes the shortcomings of existing studies, and proposes the directions for future development, in order to provide a theoretical foundation and scientific guidance for related research on HCC.

[Objective] To obtain accurate data on alanine aminotransferase (ALT) levels among blood donors in China and to explore the necessity of adjusting the qualification criteria for ALT. [Methods] A collaborative study was conducted involving 26 blood centers and 7 central blood stations with an annual testing volume exceeding 100 000 samples. Between December 1 and 15, 2024, pre-donation ALT testing was suspended for 1-2 days for all whole blood donations. ALT levels were measured only post-donation using standard laboratory equipment and reagents. All transfusion-transmitted infectious disease-related serological and nucleic acid testing, including hepatitis E virus (HEV) RNA testing, were performed. Within one week of testing completion, anonymized data on basic donor information, routine test results, and HEV RNA results were collected and statistically analyzed. [Results] A total of 21 345 blood donors were included in the study, with an ALT disqualification rate of 7.6% (1 623/21 345). The disqualification rate was 9.6% (1 453/15 205) for males and 2.8% (170/6 140) for females. There were significant regional variations in both the disqualification rates and levels of ALT, with Shaanxi Province exhibiting the highest disqualification rate (12.3%, 87/710) and Yunnan Province the lowest (2.9%, 19/652). Among the provinces (autonomous regions and municipalities), Beijing recorded the lowest ALT levels. ALT levels varied across different age groups and genders. Among all samples tested by HEV RNA, the HEV RNA positive rate was 0.29‰ (6/21 003). HCV infection was found to directly affect ALT levels, while HBV, HIV, syphilis, and HEV infections did not significantly impact ALT disqualification rates. It is recommended to adjust the ALT qualification criteria to twice the upper limit of the clinical reference range, which would increase the number of eligible blood donations by 6.61% (1 293/19 550). [Conclusion] In China, the ALT levels of blood donors are correlated with gender, age, geographical region, and HCV infection status. Appropriately raising the ALT eligibility criteria to ≤100 U/L for male donors and ≤80 U/L for female donors could expand the pool of eligible donors and reduce the blood discard rate while ensuring blood safety.

ObjectiveTo analyze the expression level of triggering receptor expressed on myeloid cells-1 (TREM-1) in serum and ascites of patients with cirrhotic ascites, and to investigate its correlation with clinical features and inflammatory markers and its role in the diagnosis of infection and prognostic evaluation. MethodsA total of 110 patients with cirrhotic ascites who were hospitalized in The Fifth Hospital of Shijiazhuang from January 2019 to December 2020 were enrolled, and according to the presence or absence of intra-abdominal infection, they were divided into infection group with 72 patients and non-infection group with 38 patients. The patients with infection were further divided into improvement group with 38 patients and non-improvement group with 34 patients. Clinical data and laboratory markers were collected from all patients. Serum and ascites samples were collected, and ELISA was used to measure the level of TREM-1. The independent-samples t test was used for comparison of normally distributed continuous data between two groups; the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups, and the Kruskal-Wallis H test was used for comparison between multiple groups; the chi-square test was used for comparison of categorical data between two groups. A Spearman correlation analysis was used to investigate the correlation between indicators. A multivariate Logistic regression analysis was used to identify the influencing factors for the prognosis of patients with cirrhotic ascites and infection. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic and prognostic efficacy of each indicator, and the Delong test was used for comparison of the area under the ROC curve (AUC). ResultsThe level of TREM-1 in ascites was significantly positively correlated with that in serum (r=0.50, P<0.001). Compared with the improvement group, the non-improvement group had a significantly higher level of TREM-1 in ascites (Z=-2.391, P=0.017) and serum (Z=-2.544, P=0.011), and compared with the non-infection group, the infection group had a significantly higher level of TREM-1 in ascites (Z=-3.420, P<0.001), while there was no significant difference in the level of TREM-1 in serum between the two groups (P>0.05). The level of TREM-1 in serum and ascites were significantly positively correlated with C-reactive protein (CRP), procalcitonin (PCT), white blood cell count, and neutrophil-lymphocyte ratio (r=0.288, 0.344, 0.530, 0.510, 0.534, 0.454, 0.330, and 0.404, all P<0.05). The ROC curve analysis showed that when PCT, CRP, and serum or ascitic TREM-1 were used in combination for the diagnosis of cirrhotic ascites with infection, the AUCs were 0.715 and 0.740, respectively. The multivariate Logistic regression analysis showed that CRP (odds ratio [OR]=1.019, 95% confidence interval [CI]: 1.001 — 1.038, P=0.043) and serum TREM-1 (OR=1.002, 95%CI: 1.000 — 1.003, P=0.016) were independent risk factors for the prognosis of patients with cirrhotic ascites and infection, and the combination of these two indicators had an AUC of 0.728 in predicting poor prognosis. ConclusionThe level of TREM-1 is closely associated with the severity of infection and prognosis in patients with cirrhotic ascites, and combined measurement of TREM-1 and CRP/PCT can improve the diagnostic accuracy of infection and provide support for prognostic evaluation.

Objective:To analyze the efficacy of combination of peginterferon α-2b(Peg-IFN α-2b)with nucleos(t)ide analogues(NAs)on antiviral therapy in children with chronic hepatitis B(CHB)and to provide an optimized clinical treatment strategies for CHB children.Methods:A retrospective analysis was conducted on 30 CHB children treated in The First Affiliated Hospital of the Army Medical University(Southwest Hospital)from January 2022 to January 2025 with treatment duration at least 48 weeks. The enrolled children were aged between 2 and 17 years and divided into the NAs combined with Peg-IFN α-2b(NPI)group(n=13)and NAs group(n=17)by their therapy regimens. The characteristics of baseline,week 12,week 24,week 48 and week 96 were compared between groups,as well as the differences in response to biochemical,immune and viral indicators at each observation point. Logistic regression analysis and receiver operating characteristic(ROC)curve analysis were performed to identify factors influencing the HBsAg seroclearance. Results:At baseline of treatment,the proportion of HBeAg positivity in the NPI group and the NAs group was high(76.9% vs 86.6%, χ2=0.679, P=0.628),and the alanine aminotransferase(ALT)and aspartate aminotransferase(AST)in the NPI group were significantly lower than those in the NAs group( P<0.001). At 24 weeks,the decrease in HBsAg in the NPI group was also significantly higher than that in the NAs group( Z=-3.161, P=0.002). Finally,the cumulative seroclearance rate of HBsAg at 96 weeks in the NPI group was significantly higher than that in the NAs group(46.15% vs 5.88%, χ2=0.679, P=0.025). Mulitivariate Logistic regression analysis showed that treatment regimen and gender were risk factors affecting the outcome of HBsAg( P<0.05). ROC curve analysis showed that the increase in ALT at 12 weeks compared with baseline(AUC=0.857,Cutoff value=3.615 IU/L),the decrease in ALT at 24 weeks(AUC=0.870,Cutoff value=47.85 IU/L),and the decrease in HBsAg at 12 weeks and especially at 24 weeks(AUC=0.885,Cutoff value=0.97log IU/ml)were effective predictors of HBsAg prognosis at 96 weeks. Conclusion:In CHB children,antiviral regimen Peg-IFN α-2b combined with NAs was more effective than NAs alone in improving the HBsAg seroclearance rate of CHB,and the effects in female were better than in male. The decline of HBsAg and the fluctuation of ALT in the early treatment period are valid predictors of HBsAg clearance.
