ObjectivePolygoni Multiflori Radix is a commonly used tonic traditional Chinese medicine （TCM） in clinical practice， but liver injury has often been reported in recent years. Some related preparations containing Polygoni Multiflori Radix have been reported by the National Medical Products Administration many times for the risk of liver injury. This has caused extensive discussion on the potential toxicity of TCM in China and abroad， which has limited the clinical use of Polygoni Multiflori Radix to some extent. To understand the adverse reactions of Polygoni Multiflori Radix， the safe and rational use of Polygoni Multiflori Radix in clinical practice was discussed. MethodsThe pharmacovigilance thought of modern Chinese medicine and the TCM pharmacovigilance system framework of ''identification of poison， use of poison， anti-poison， and detoxification'' were employed to mine the relevant toxicity records， usage and dosage， processing compatibility， and contraindication of taking Polygoni Multiflori Radix in ancient books. The drug safety information of Polygoni Multiflori Radix was summarized by comparing with modern reports. ResultsA total of 74 ancient books related to Polygoni Multiflori Radix were included， suggesting that the toxicity of Polygoni Multiflori Radix was recognized in ancient times. The main chemical components of Polygoni Multiflori Radix had both efficacy and toxicity， and the adverse reactions may be related to long-term use， excessive use， and individual differences. The results showed that the toxic components of Polygoni Multiflori Radix could be reduced by peeling， steaming with black beans， and processing without iron tools. The toxic effects of Polygoni Multiflori Radix could be reduced by the compatibility of Polygoni Multiflori Radix with Poria， Psoraleae Fructus， and Cistanches Herba. ConclusionReasonable dosage， standard processing， correct compatibility， and syndrome differentiation are the key points to standardize the use of Polygoni Multiflori Radix and reduce the incidence of adverse reactions. Clinically， the toxicity classification of TCM should be strengthened， and the susceptible population should be prioritized. The detection indicators and early warning mechanisms should be improved， and precise drug dosage and course of treatment should be guaranteed. These measures can ensure the safe use of Polygoni Multiflori Radix.

Objective: To fabricate a hydrogel loaded with inositol hexaphosphate-zinc and preliminarily evaluate its performance in self-mineralization and osteoinduction, thereby providing a theoretical basis for the development of bone regeneration materials. Methods: The hydrogel framework (designated DF0) was formed by copolymerizing methacryloyloxyethyltrimethylammonium chloride and four-armed poly(ethylene glycol) acrylate, followed by sequentially loading inositol hexaphosphate anions via electrostatic interaction and zinc ions via chelation. The hydrogel loaded only with inositol hexaphosphate anions was named DF1, while the co-loaded hydrogel was named DF2. The self-mineralization efficacy of the DF0 , DF1 and DF2 hydrogels was characterized using scanning electron microscopy, transmission electron microscopy (TEM), energy dispersive spectroscopy (EDS), and selected area electron diffraction (SAED). The biocompatibility was assessed via live/dead cell staining and a CCK-8 assay. The osteoinductive capacity of the DF0 , DF1 and DF2 hydrogels on MC3T3-E1 cells was assessed via alkaline phosphatase (ALP) and Alizarin Red S (ARS) staining. In the aforementioned cell experiments, cells cultured in standard medium served as the control group Results: The DF0, DF1, and DF2 hydrogels were successfully synthesized. Notably, DF1 and DF2 exhibited distinct self-mineralization within 6 days. Results from TEM, EDS, and SAED confirmed that the mineralization products were amorphous calcium phosphate in group DF1, and amorphous calciumzinc phosphate in group DF2. Biocompatibility tests revealed that none of the hydrogels (DF0, DF1, and DF2) adversely affected cell viability or proliferation. In osteogenic induction experiments, both ALP and ARS staining were intensified in the DF1 and DF2 groups, with the most profound staining observed in the DF2 group. Conclusion The developed inositol hexaphosphate-zinc hydrogel (DF2) demonstrates the dual capacity to generate calcium-phosphate compounds through self-mineralization while exhibiting excellent osteoinductive properties. This biocompatible, dual-promoting osteogenic hydrogel presents a novel strategy for bone regeneration.

Objective: To validate the performance of the Procleix UltrioPlex E assay (Grifols, Spain) on the Procleix Panther automated nucleic acid detection platform, which employs the TMA method to simultaneously detect HIV-1/HIV-2/HCV/HBV/HEV viruses, and to evaluate its value for screening transfusion-associated infectious diseases. Methods: In accordance with the requirements of ISO15189"Application of the Guidelines for the Accreditation of Quality and Capabilities of Medical Laboratories in the Field of Molecular Diagnostics (CNAS-CL02-A009: 2018)", "Guidelines for Performance Validation of Molecular Diagnostic Testing Procedures (CNAS-GL039: 2019)", and the "Technical Operating Procedures for Blood Banks (2019 Edition)", this study validated the reagent's performance in terms of analytical sensitivity validation, performance consistency validation, interference resistance, and cross-contamination resistance. Results: Probit analysis revealed that the 95% detection limits (95% confidence interval) for HBV, HCV, HIV, and HEV were 2.0 IU/mL, 1.5 IU/mL, 18.0 IU/mL and 3.7 IU/mL, respectively, which were consistent with the minimum detection limits stated in the kit's package insert and were comparable to the Procleix Ultrio Elite kit. Both kits were used to test the performance validation serum plate simultaneously, yielding results consistent with the serum plate (Kappa=1), indicating stable performance. Detection of medium-and low-concentration lipemia and weakly positive hemolysis samples demonstrated good interference resistance. Cross-contamination performance validation showed that the kit exhibited excellent cross-contamination resistance. Conclusion: The Procleix UltrioPlex E nucleic acid detection kit enables combined detection of HIV-1, HIV-2, HCV, HBV, and HEV, allowing single-test screening for multiple viruses in donor blood. The kit's analytical performance is stable and meets basic laboratory requirements, making it suitable for screening transfusion-associated infectious diseases in blood banks.

The active components in traditional Chinese medicine （TCM） generally have problems such as poor solubility and low bioavailability， which seriously restrict their clinical efficacy. In recent years， TCM nano-self-assembly based on the non-covalent interactions between molecules has become the research frontier in this field because it can spontaneously form an orderly structure and improve the insoluble components in the body. Moreover， TCM nano-self-assembly has shown unique advantages in the treatment of fibrosis， inflammatory and immune diseases， infectious diseases， and cancer. This article summarizes the research context， structural system， and potential as a pharmacological substance basis of TCM nano-self-assembly by reviewing recent published studies， with focuses on the application of TCM nano-self-assembly in the treatment of diseases from single components to complex systems. In addition， this article summarizes its advantages， mechanism characteristics， and main challenges faced. At present， this field still faces issues such as insufficient mechanism research， a lack of in-depth understanding of the competitive assembly rules of multiple components， difficulty in quality control， unclear in vivo processes and safety， and obstacles to clinical translation. To address these issues， this article proposes a series of solutions， including introducing molecular dynamics simulation and artificial intelligence to predict assembly behavior， using experimental techniques to analyze non-covalent interactions， establishing a comprehensive evaluation system with multiple indicators， using isotope labeling and in vivo imaging techniques to dynamically track in vivo processes， conducting standardized safety evaluation， promoting the filing of hospital preparations and new drug applications， and strengthening early communication between research and regulation. Finally， this article points out the future development directions， aiming to provide reference for subsequent research and clinical translation.

Objective To investigate the predictive value of D-dimer for in-hospital mortality and heart failure with reduced ejection fraction (HFrEF) in patients with acute myocardial infarction (AMI). Methods A total of 688 patients with AMI who were hospitalized at Zhongshan Hospital, Fudan University, from January 2020 to December 2023 were retrospectively enrolled. Demographic and clinical characteristics, laboratory findings, echocardiographic parameters, and in-hospital outcomes were collected. Patients were divided into four groups according to D-dimer quartiles, and trend tests were used to compare changes in each indicator with increasing D-dimer levels. The primary endpoints were in-hospital mortality and HFrEF. Multivariable logistic regression analysis was performed to assess the independent associations of D-dimer with in-hospital mortality and HFrEF. Receiver operating characteristic (ROC) curve analysis was used to evaluate its predictive performance. Results Differences and trend tests among four groups for age, creatinine, peak cardiac troponin T, N-terminal pro-brain natriuretic peptide (NT-proBNP), left ventricular ejection fraction, HFrEF incidence, and in-hospital mortality were statistically significant (P＜0.05). Multivariable logistic regression analysis showed that elevated D-dimer was associated with an increased risk of in-hospital mortality in patients with AMI (OR＝1.251, 95%CI 1.093–1.432, P＝0.001), and HFrEF (OR＝1.075, 95%CI 1.028–1.124, P＝0.002). ROC curve analysis showed that the area under the curve (AUC) of D-dimer for predicting in-hospital mortality and HFrEF were 0.871 and 0.716, respectively. At a cutoff value of 0.47 mg/L, the sensitivity and specificity of D-dimer in predicting HFrEF were 81.9% and 52.1%, respectively; at a cutoff value of 2.18 mg/L, the sensitivity and specificity of D-dimer in predicting in-hospital mortality were 63.6% and 93.8%, respectively. Restricted cubic spline analysis demonstrated significant non-linear associations between D-dimer and the risks of in-hospital mortality and HFrEF (P＜0.001). Conclusions Elevated D-dimer level is significantly associated with increased risks of in-hospital mortality and HFrEF in patients with AMI and shows acceptable predictive performance. As a simple and readily available laboratory biomarker, D-dimer may provide useful information for early risk stratification and clinical management in patients with AMI.

The recombinant human thyroid-stimulating hormone (rhTSH) can be used for differentiated thyroid cancer (DTC) preparation before ¹³¹I therapy, and follow-up. Since its approval by the American Food and Drug Administration (FDA) in 1998, rhTSH has been clinically used in European countries, the United States, and other countries for nearly 30 years. In April 2024, China’s first independently developed rhTSH agent was approved. Based on clinical experience and evidence from domestic and international studies, an expert consensus on the application of rhTSH has been developed following thorough consultations among experts. The consensus offers evidence-based recommendations to guide the appropriate use of rhTSH in clinical practice.

Objective To investigate the relationship between serum microRNA-101-3p(miR-101-3p),pol-ypeptide N-acetylgalactosaminyltransferase 1(GALNT1)and the efficacy and prognosis of neoadjuvant chem-otherapy(NAC)in breast cancer.Methods A total of 203 breast cancer patients who underwent NAC in this hospital from January 2017 to August 2019 were selected as breast cancer group.They were divided into the ineffective group and the effective group according to the therapeutic effect of NAC,and divided into the death group and the survival group according to the 5-year survival situation.Additionally,203 healthy women who underwent routine physical examination during the same period were selected as the control group.The clini-cal data and the levels of serum miR-101-3p and GALNT1 were detected and compared.The binding sites of miR-101-3p and GALNT1 were predicted through the online database.Pearson correlation analysis was per-formed to assess the correlation between serum miR-101-3p and GALNT1 expression in breast cancer pa-tients.The relationship between serum miR-101-3p,GALNT1 and the efficacy and prognosis of NAC in breast cancer patients were analyzed by multivariate unconditional Logistic regression and Cox regression.The pre-dictive value of serum miR-101-3p and GALNT1 for the ineffectiveness and mortalit of NAC treatment in breast cancer patients were analyzed by receiver operating characteristic(ROC)curve.Results Compared with the control group,the expression level of serum miR-101-3p in the breast cancer group decreased,and the level of GALNT1 increased,and the differences were statistically significant(P＜0.05).Serum miR-101-3p in patients with breast cancer was negatively correlated with GALNT1(P＜0.05).High expression of Ki-67,≥4 axillary lymph node metastases after surgery and high expression of GALNT1 were independent risk factors for ineffective NAC treatment in breast cancer patients(P＜0.05),and high expression of miR-101-3p was an independent protective factor(P＜0.05).TNM stage Ⅲ,postoperative axillary lymph node metastasis ≥10,and high expression of GALNT1 were independent risk factors for ineffective NAC treatment in breast cancer patients(P＜0.05),while high expression of miR-101-3p was an independent protective fac-tor(P＜0.05).The predictive efficacy of combined detection of serum miR-101-3p and GALNT1 for ineffec-tive NAC treatment and death in breast cancer patients was higher than that predicted by either of them alone(both P＜0.05).Conclusion Low serum miR-101-3p and high GALNT1 expression in breast cancer patients are closely related to NAC efficacy and prognosis.The combination of the two has a high predictive value for both the efficacy and prognosis of NAC.

Objective To investigate the clinical characteristics and influencing factors of pressure injury in patients with severe neurological diseases and to construct and evaluate a predictive model for it.Methods A retrospective research method was adopted to collect 250 patients with severe neuropathy admitted to the First Affiliated Hospital of Wenzhou Medical University from April 2020 to April 2024,and their clinical characteristics were collected.The patients were then divided into a pressure injury group(n=58)and a non-pressure injury group(n=192)based on whether they development pressure injury after treatment.Baseline data on patient coma or lethargy status,primary diagnosis requiring neurocritical care admission,and Acute Physiology and Chronic Health Evaluation(APACHE)Ⅱscores were collected.The area under the curve(AUC)of the receiver operating characteristic(ROC)curves for acute cerebrovascular disease,coma or lethargy status,and APACHE Ⅱ scores of the subjects was compared.Results Among the 250 patients with severe neurological diseases,58 had pressure injuries.Of these,35(60.34%)had mucosal pressure injuries,while 23(39.66%)had device-related pressure injuries.According to the National Pressure Injury Advisory Panel Pressure Injury Staging System,46 cases(79.31%)had stage 1 pressure injuries,8 cases(13.97%)had stage 2 pressure injuries,4 cases(6.90%)had stage 3 pressure injuries,and no patients had stage 4 pressure injuries.Logistic multivariate regression analysis showed that primary diagnosis requiring neurocritical care admission(odds ratio[OR]=3.102;95%CI,1.013-9.499),coma or lethargy status(OR=3.769;95%CI,1.237-11.478),and APACHE Ⅱ score(OR=0.201;95%CI,0.124-0.328)were influencing factors for pressure injury in patients with severe neurological diseases.The ROC results showed that the AUC of the prediction model combining the 3 influencing factors was 0.974(95%CI,0.957-0.992),and that the sensitivity and specificity were 91.40%and 93.70%,respectively.The prediction accuracy of the combination prediction model was 0.96,which was significantly higher than those of the prediction models based on the 3 separate influencing factors(P<0.05).The Hosmer-Lemeshow test showed that the model had a good fit(χ2=4.779,P=0.062),indicating that the model had a relatively high accuracy.Conclusion Acute cerebrovascular disease,coma or lethargy,and APACHE Ⅱ score have different predictive values for pressure injury in patients with severe neurological diseases.While acute cerebrovascular disease and coma or lethargy have the same predictive value separately,the combination prediction incorporating the 3 influencing factors demonstrated superior accuracy and holds considerable potential for clinical application.
