Puerariae Lobatae Radix and Puerariae Thomsonii Radix are the dried roots of Pueraria lobata and Pueraria thomsonii of the Leguminosae family， respectively. Since their separate inclusion in the 2005 edition of Pharmacopoeia of the People's Republic of China， the two herbs have been individually recorded. Although they share the same functions and indications， the required content of puerarin differs by a factor of up to eightfold between them. The current quality standard relies solely on a single indicator， puerarin， which fails to reflect the correlation between chemical constituents and core therapeutic effects. This has resulted in prominent issues of mixed use in clinical practice and production， thereby constraining the high-quality development of the industry. Modern research has demonstrated that Puerariae Lobatae Radix contains a comprehensive range and higher content of isoflavonoid constituents， while Puerariae Thomsonii Radix is rich in starch and polysaccharides. Puerariae Lobatae Radix exhibits stronger effects in antipyresis， cardiovascular and cerebrovascular protection， and central analgesia， while Puerariae Thomsonii Radix demonstrates greater advantages in anti-inflammation， hypoglycemia， and peripheral analgesia. Based on this， the chemical material bases of Puerariae Lobatae Radix and Puerariae Thomsonii Radix at both the macromolecule and micromolecule levels were systematically reviewed and compared. The pharmacodynamic material bases and mechanisms of action underlying their three core therapeutic effects， namely "relieving exterior syndrome and clearing heat"， "promoting fluid production to quench thirst"， and "dredging channels and activating collaterals"， were summarized. The most highly correlated common metabolic pathway shared by both herbs for these three therapeutic effects is the arachidonic acid metabolic pathway， and their common core target is prostaglandin-endoperoxide synthase 2 （PTGS2）. This review provided clinical application recommendations based on the therapeutic differences between the two herbs， elucidated the scientific connotation of their "same origin but different effects"， and， grounded in the quality marker （Q-Marker）， proposed the concept of efficacy-related Q-Marker based on "substance-efficacy-syndrome" association， as well as a novel strategy for efficacy-oriented quality evaluation. Preliminary screening of quality markers associated with different therapeutic effects was also conducted. This study aims to provide critical scientific evidence for the precise clinical application of Puerariae Lobatae Radix and Puerariae Thomsonii Radix， the improvement of quality standards， and the high-quality development of the industry.

Objective: To evaluate the causal effects and population heterogeneity of Guangzhou′s Voluntary Blood Donation Privilege Certificate Policy on blood donation behavior, and to provide empirical evidence for optimizing blood management policies. Methods: Using an interrupted time series (ITS) design, we analyzed 30 quarters of blood collection data from Guangzhou Blood Center (from July 2018 to December 2025). Taking the third quarter of 2021 as the intervention node, we constructed ordinary least squares (OLS) regression models incorporating level and trend effects, and conducted stratified analyses by gender, age group, previous donation frequency, and per-donation volume. Results: The tiered incentive policy demonstrated significant heterogeneous effects. Apheresis donations showed sustained growth, with 2 units of component blood exhibiting a significant trend effect (β=304.58, P<0.001); high-frequency donors (11+ times) demonstrated sustained growth trends in apheresis donations. For whole blood, immediate effects were significant for donors with 1-2 previous donations (β=4 537.55, P<0.001) and 3-10 previous donations (β=2 159.69, P<0.05); high-frequency donors (11-30 times) showed sustained growth trends (P<0.01). Stratified by per-donation volume, 400 mL whole blood demonstrated a significant immediate effect (β=4 391.01, P<0.1), while 200 mL whole blood showed a significant declining trend (β=-893.24, P<0.01). Conclusion: The tiered incentive policy effectively enhanced blood donation participation while maintaining the donors’ altruistic motivations. Young and middle-aged adults primarily drove apheresis donations. The policy demonstrated immediate incentive effects on low-frequency whole blood donors and long-term retention effects on high-frequency donors. Per-donation volume showed an "upward migration" trend, optimizing the blood collection structure. Differentiated outreach, conversion and retention strategies are recommended to further strengthen blood supply security.

Objective To explore the correlation between central venous oxygen saturation(ScvO2)-re-lated indexes at different time points and the occurrence of low cardiac output syndrome(LCOS)after con-genital heart disease(CHD)correction surgery.Methods A total of 73 children who underwent CHD correc-tion surgery in this hospital from July 1st,2021 to July 1st,2024 were selected as the research subjects.The clinical data,preoperative conditions,and postoperative conditions of the children were collected.The ScvO2 and arterial lactate(Lac)levels of the children at different time points(the 1st,6th,12th,and 24th hours after surgery)were monitored,and the ScvO2/Lac at different time points and the change rate of ScvO2 in different time periods were calculated.The correlation between ScvO2-related indexes and LCOS after CHD correction surgery was analyzed.Results ScvO2 at the 6th hour after surgery,ScvO2 at the 12th hour after surgery,Sc-vO2/Lac at the 12th hour after surgery,the change rate of ScvO2 from the 1st to the 24th hour after surgery,the change rate of ScvO2 from the 6th to the 12th hour after surgery,and the change rate of ScvO2 from the 12th to the 24th hour after surgery were independent influencing factors of LCOS occurrence after CHD cor-rection surgery(P＜0.05).There was a negative correlation between ScvO2 at the 12th hour after surgery,ScvO2/Lac and LCOS occurrence after CHD correction surgery(r=-0.543,-0.523,P＜0.05).The area under the curve(AUC)of ScvO2 at the 12th hour after surgery for predicting LCOS occurrence after CHD correction surgery was 0.938(95％CI:0.865-1.000);the AUC of ScvO2/Lac at the 12th hour after surgery for predicting LCOS occurrence after CHD correction surgery was 0.922(95％CI:0.851-0.994).Conclusion ScvO2 and ScvO2/Lac at the 12th hour after surgery have good predictive potential for LCOS occurrence af-ter CHD correction surgery.

Triple-negative breast cancer (TNBC) is aggressive, with high recurrence rates and poor prognosis. Paclitaxel (PTX) remains a key chemotherapeutic agent for TNBC, but its efficacy diminishes due to the emergence of drug resistance, largely driven by cancer stem-like cells (CSCs), vasculogenic mimicry (VM) formation and tumor immunosuppressive microenvironment (TIME). Pyruvate kinase M2 (PKM2) is highly expressed in TNBC, and is a potential target for TNBC treatment. In this study, we developed a biomimetic codelivery system using albumin nanoparticles (termed S/P NP) to co-encapsulate PTX and shikonin (SHK), a natural inhibitor of PKM2. By inhibiting PKM2, SHK suppressed β-Catenin signaling, thereby reversing CSC stemness and preventing VM formation. The S/P NP system exhibited tumor-targeting delivery effect and significantly inhibited TNBC growth and lung metastasis. Mechanistically, the treatment reversed epithelial-mesenchymal transition (EMT) and stem-like properties of TNBC cells, suppressed VM formation, and remodeled the TIME. It reduced immunosuppressive cells (M2 macrophages, MDSCs) while promoting anti-tumor immunity (M1 macrophages, dendritic cells, cytotoxic T cells, and memory T cells). This dual-action strategy holds promise for improving TNBC therapy by targeting CSCs, VM, and the immune microenvironment, and for overcoming PTX resistance and reducing metastasis.

Dust and chemical substances are widely present occupational hazards in workplaces. Long-term exposure to dust and chemical substances can pose serious threats to workers′ health. Owing to their advantages in real-time detection, rapid response, and high accuracy, online monitoring technologies enable continuous measurement and analysis of the concentration and composition of dust and chemical substances in workplaces. These technologies provide timely and effective data support for the prevention and control of occupational diseases and have become an important protective tool in the field of occupational hazard. Current online monitoring technologies for workplace dust mainly include the tapered element oscillating microbalance method, light scattering method, β-ray method, triboelectric charging, video exposure monitoring, and ultrasonic methods. Online monitoring devices for workplace chemical substances are still in the early stages of development. However, this equipment has been partially applied in environmental monitoring, covering methods such as spectral analysis, electrochemical sensors, cataluminescence sensors, and intelligent sensing systems. In the future, the development of online dust monitoring technology should focus on overcoming technical bottlenecks to improve detection accuracy and exploring the synergistic effects of different technologies to compensate for the limitations of single methods. Meanwhile, online monitoring technologies for chemical substances should aim to develop integrated detection systems that combine high precision, real-time performance, low cost, and stability.

Objective Based on the background of disease diagnosis related groups(DRGs)in public hospitals to construct the nursing quality evaluation index system for percutaneous radiofrequency ablation(PRFA)of liver cancer so as to improve the nursing quality for PRFA of liver cancer.Methods Using three-dimensional quality model and through interview,literature analysis,two rounds of Delphi expert letter inquiry and analytic hierarchy process,the evaluation standard of PRFA nursing quality of liver cancer was established,and its effect was validated in clinical practice.Results The evaluation index system of PRFA nursing quality for liver cancer was constructed,which included 3 first-level indexes,9 second-level indexes and 22 third-level indexes.After clinical application,the incidence of intraoperative and postoperative moderate-severe pain,the incidence of high fever,and the 24-hour number of times required care in the intervention group were lower than those in the control group(P＜0.05),the incidence of postoperative Ⅲ degree vomiting in the intervention group was remarkably lower than that in the control group(P＜0.01),and the average hospitalization days in the intervention group were less than those in the control group(P＜0.05),and the average hospitalization expense in the intervention group was lower than that in the control group,but the difference was not statistically significant(P＞0.05).Conclusion The PRFA nursing quality evaluation index system for liver cancer is scientific and practical,which is helpful for improving the outcome of patients and promoting the quality of nursing.

ObjectiveTo investigate the value of prealbumin-to-total bilirubin （PA/TBil） ratio on admission in predicting 90-day mortality or liver transplantation in patients with HBV-related acute-on-chronic liver failure （HBV-ACLF）， as well as the effect of its combination with Model for End-Stage Liver Disease （MELD） score on the predictive performance for short-term prognosis. MethodsA retrospective analysis was performed for the clinical data of 216 HBV-ACLF patients who were admitted to Department of Infectious Diseases in the First Affiliated Hospital of Soochow University from April 2020 to May 2025， and the patients were followed up for 3 months. According to the outcome， the patients were divided into survival group with 104 patients and death/transplantation group with 112 patients. The Kolmogorov-Smirnov test was used to check whether the continuous data was in accordance with the normal distribution； the two-independent-samples t test was used for comparison of normally distributed continuous data between two groups， while the Mann-Whitney U test was used for comparison of continuous data with skewed distribution between two groups. The chi-square test was used for comparison of categorical data between two groups. Univariate and multivariate binary Logistic regression analyses were used to investigate the influencing factors for prognosis， and the receiver operating characteristic （ROC） curve was used to analyze the performance of each indicator in predicting the prognosis of ACLF. The area under the ROC curve （AUC） was calculated， and the Delong test was used for comparison of AUC. ResultsA total of 216 patients were enrolled in this study， with a 90-day survival rate of 48.15% （104/216）. Compared with the death/transplantation group， the survival group had significantly higher platelet count， lymphocyte count， albumin， and PA/TBil ratio （all P<0.05） and significantly lower age， white blood cell count， neutrophil count， prothrombin time， international normalized ratio， aspartate aminotransferase， total bilirubin， creatinine， and MELD score （all P<0.05）. The multivariate Logistic regression analysis showed that age （odds ratio ［OR］=1.05， 95% confidence interval ［CI］： 1.02 — 1.09， P<0.001）， PA/TBil ratio （OR=0.16， 95%CI： 0.05 — 0.46， P<0.001）， and MELD score （OR=1.09， 95%CI： 1.01 — 1.17， P=0.024） were independent influencing factors for 90-day prognosis in HBV-ACLF patients. PA/TBil ratio and MELD score used alone or in combination had an AUC of 0.760， 0.779， and 0.811， respectively， in predicting the prognosis of HBV-ACLF patients， and PA/TBil ratio combined with MELD score had a better AUC than PA/TBil ratio or MELD score used alone （Z=-2.058 and 2.017， both P<0.05）. ConclusionBoth serum PA/TBil ratio and MELD score can effectively predict the prognosis of patients with HBV-ACLF， and a combination of the two indicators had a better predictive performance than MELD score alone， which provides an important reference for clinical risk stratification management and timely intervention.

Objective To investigate the technical capacity and service quality of occupational health technical service institutions (hereinafter referred to as "occupational health institutions") in Guangdong Province. Methods All occupational health institutions in Guangdong Province that had valid occupational health service qualifications and within the validity period were included for analysis. Data on basic information, employed personnel, and results of professional technical capacity assessments across occupational health institutions were obtained through the Guangdong Provincial Occupational Health Technical Quality Control Center.
