As people’s attention to health continues to increase, the market demand for traditional Chinese medicine (TCM) is growing steadily. The quality and safety of Chinese medicinal materials have attracted unprecedented social attention. In particular, the issue of exogenous harmful residue pollution in TCM has become a hot topic of concern for both regulatory authorities and society. The Chinese Pharmacopoeia 2025 Edition further refines the detection methods and limit standards for exogenous harmful residues in TCM. This not only reflects China’s high-level emphasis on the quality and safety of TCM but also demonstrates the continuous progress made by China in the field of TCM safety supervision. Basis on this study, by systematically reviewing the development history of the detection standards for exogenous harmful residues in TCM and analyzing the revisions and updates of these detection standards in the Chinese Pharmacopoeia 2025 Edition, deeply explores the key points of the changes in the monitoring standards for exogenous harmful residues in TCM in the Chinese Pharmacopoeia 2025 Edition. Moreover, it interprets the future development directions of the detection of exogenous residues in TCM, aiming to provide a reference for the formulation of TCM safety supervision policies.

ObjectiveTo investigate the trends in diabetes mortality and potential years of life lost (PYLL) among residents of Huangpu District, Shanghai from 1993 to 2021, to analyze the long-term trends of diabetic patients with different characteristics and to provide a reference for scientific prevention and control of diabetes in aging urban areas. MethodsDiabetes mortality data were obtained from the Huangpu District cause of death registration records in the Shanghai death cause registration system. Indicators such as crude mortality rate, standardized mortality rate, potential years of life lost (PYLL), average years of life lost (AYLL), annual percentage change (APC), and average annual percentage change (AAPC) were used to analyze diabetes-related mortality and life loss. Statistical analyses were performed using software SPSS 21.0 and Joinpoint 5.0.2. ResultsFrom 1993 to 2021, the average annual crude mortality rate of diabetes in Huangpu District was 46.56/100 000, and the average annual standardized mortality rate was 20.44/100 000. The crude mortality rate and standardized mortality rate of diabetes for female residents were higher than those for males. The crude mortality rate showed an overall increasing trend [AAPC=2.81% (95%CI: 0.20%‒5.49%), P<0.05], while the increase in standardized mortality rate significantly slowed [AAPC=0.15% (95%CI: -2.27%‒2.63%)], P<0.05]. The mortality rate rose rapidly in the 70‒74 years age group and peaked in the 85‒ years age group (607.69/100 000). Diabetes accounted for a cumulative PYLL of22 741 person-years, with an average annual AYLL of 1.88 years and an average annual potential years of life lost rate (PYLLR) of 0.82‰. Male residents had higher PYLL, AYLL, and PYLLR than females. ConclusionDiabetes mortality rates in Huangpu District have increased year by year, resulting in significant life loss. However, the age-standardized mortality rate increase has markedly slowed. Efforts should focus on elderly diabetic patients aged ≥70 years, by leveraging platforms such as community-based chronic disease health support centers, efforts should be made to enhance diabetes screening service for middle-aged and elderly residents. Consequently, elderly diabetic patients’ awareness of diabetes and responce to related complications is improved, which would be conducive to controling the progression of complications and reducing the mortolity risk of diabetes.

GBA1 gene mutation is an important genetic risk factor for Parkinson’s disease (PD). This paper reports a case of a 43-year-old male PD patient carrying a rare heterozygous Thr408Met mutation in the GBA1 gene identified through whole-exome sequencing, leading to a diagnosis of GBA1-associated PD. The patient’s motor symptoms were primarily characterized by bradykinesia and rigidity, without significant cognitive decline. Treatment with low-dose levodopa combined with a dopamine agonist resulted in significant symptomatic improvement.

With the explosive growth of knowledge and technologies in biological disciplines repre-sented by omics techniques,which promise broad applications in the field of toxicology.New methods of alternative toxicology to non-animal testing based on transcriptomics are entering the regulatory phase.However,given the limitations of a single omics technique in risk assessment and the fact that the transition from scientific research to regulatory specification has not yet been realized,risk assess-ment will be helped to be accomplished more accurately by integrating multiple new approach method-ologies(NAMs)and different information sources.This review introduces genomics,proteomics,protein post-translational modification genomics and metabonomics,which are currently the focus of attention both at home and abroad,and their prospective applications in chemical risk assessment.

Objective:To analyze and explore the effects of Huayu Jiedu Decoction on the malignant biological characteristics of multiple myeloma(MM)cells and its molecular mechanism,so as to provide experimental basis and theoretical basis for the alternative therapy of anti-MM in traditional Chinese medicine.Methods:Different concentrations of Huayu Jiedu Decoction were used to intervene myeloma U266 cells.The changes of cell proliferation activity were detected by CCK-8 assay,apoptosis was detected by Annexin V/PI double staining flow cytometry,and apoptosis and protein expression of related signaling pathways were detected by Western blot.Real-time quantitative PCR was used to detect mRNA expression changes of high mobility group protein B1(HMGB1),CXC chemokine receptor 4(CXCR4)and interleukin-6(IL-6).Results:Huayu Jiedu Decoction inhibited the proliferative activity of U266 cells and induced their apoptosis in a concentration and time dependent manner(r=-0.713,r=-0.827).After treatment with Huayu Jiedu Decoction for 48 h,the expressions of anti-apoptotic protein Bcl-2 and survivin were down-regulated,while the expression of pro-apoptotic protein Bax was up-regulated,and the phosphorylation level of TLR4/NF-κB signaling pathway was inhibited.After intervention of Huayu Jiedu decoction,the expressions of HMGB1 and IL-6 mRNA were significantly decreased,while the expression of CXCR4 was not significantly decreased.Conclusion:Huayu Jiedu Decoction can inhibit the proliferative activity of U266 cells and induce programmed death.Its molecular mechanism may be related to regulating the expression of apoptotic proteins,inhibiting the activation of TLR4/NF-κB pathway and down-regulating the expression of HMGB1 and IL-6 mRNA.

Objective:To investigate the effects of Curcumol on the malignant biological characteristics of acute myeloid leukemia (AML)cells and its molecular mechanism,and to provide theoretical and experimental evidence for the anti-leukemia treatment of traditional Chinese medicine.Methods:After the AML cell lines HL-60 and KG-1 cells were treated different concentrations of with Curcumol.The proliferation activity of cells was detected by CCK-8 method,and the expression changes of apoptotic proteins and PI3 K/AKT signaling pathway proteins were detected by Western blot. Real-time quantitative fluorescence polymerase chain reaction (RT-qPCR ) was used to detect the expression of Caspase family mRNA.Results:Curcumol could inhibit the proliferation and induce apoptosis of HL-60 and KG-1 cells,promote apoptosis by up-regulating the expression of Bax and down-regulating the expression of Bcl-2 protein (P<0.05).When Curcumol interferes with HL-60 and KG-1 cells,it can also induce programmed cell death of AML by inhibiting PI3 K/AKT signaling pathway.In addition,after the intervention of Curcumol,the expression of Caspase 3,Caspase 6,Caspase 8 and Caspase 9 were up-regulated in HL-60 cells (P<0.05 ),the expression of Caspase 3,Caspase 8 and Caspase 9 were significantly up-regulated in KG-1 cells (P<0.01),while the expression of Caspase 6 was weakly affected (P<0.05 ),but low concentration of Curcumol (<60 μg/ml)had no effect on the expression of Caspase 6 in KG-1 cells (P>0.05).Conclusion:Curcumol may mediate the programmed death of AML cells by inhibiting the PI3K/AKT signaling pathway,affecting the expression of Bcl-2 family proteins,and promoting the activation of core members of Caspase family,so as to play an anti-leukemia role.

This study adopted the policy text analysis method,review the historical background of the enactment,aimed to comparatively analyze the international pharmaceutical trade policies of the BRICS countries.The main objectives of the BRICS countries'international pharmaceutical trade policies included ensuring stable and accessible drug supply,expanding exports of domestic products and creating a favorable political environment.For these purposes,Brazil,Russia,and South Africa all ensure drug supply through substantial imports.However,they have also taken measures such as compulsory patent licensing and promoting localization of production by foreign companies to reduce import dependence.India,on the other hand,protects its domestic industry by resisting drug imports to ensure drug supply while simultaneously promoting the export of pharmaceutical products.China continually optimizes approval and data monitoring procedures to align with international standards,creating a favorable trade environment and expanding exports.China should further refine its international pharmaceutical trade policies while ensuring the autonomy of domestic drug research and supply,fostering stronger collaboration within BRICS nations and promoting global access to public healthcare products.

Objective:To compare the aortic remodeling of the Fabulous stent system and standard thoracic aortic endovascular repair (TEVAR) on distal aorta type B aortic dissection (TBAD). Methods:The prospective data collected between Dec 2017 and Oct 2019 from 134 patients with type B aortic dissection (TBAD) who underwent treatment with the "Fabulous" stent system, and retrospective data from 159 TBAD patients receiving standard TEVAR from corresponding multicenter. By using propensity score matching analysis, we compared the prognosis and aortic remodeling outcomes in patients undergoing Fabulous and standard TEVAR treatments during a 1-year postoperative follow-up.Results:In this study, 62 patients in Fabulous group and 62 patients in standard TEVAR were included.There were no significant statistical differences in baseline characteristics between the two groups. In terms of aortic remodeling in bare stent region, Fabulous group had better change trends of diameter of true lumen [10.6 (4.4, 14.5) mm vs. 4.7 (0.9, 10.7) mm, P=0.001] and false lumen [-24.2 (-30.5, -4.9) mm vs. 0.7 (-11.8, 2.3) mm, P<0.001] than those in the standard TEVAR group. The rate of complete false lumen thrombosis was also higher in the Fabulous group (62.9% vs. 37.1%, P=0.042). Conclusion:The Fabulous stent system, when compared to standard TEVAR surgery, demonstrates good aortic remodeling outcomes in the distal aorta.

Objective:To investigate the relationship between the inflammatory cytokines level in the plasma of nasopharyngeal carcinoma patients before radiotherapy and acute radiotherapy adverse reactions, and to establish a preliminary model for predicting the risk of severe acute adverse reactions during radiotherapy.Methods:A cross-sectional study was conducted. A total of 85 nasopharyngeal carcinoma patients who received radical radiotherapy in Cancer Hospital of Chinese Academy of Medical Sciences from May 2016 to March 2019 were retrospectively collected. The highest grade adverse reactions of radiation oral mucositis, radiation dermatitis and xerostomia during radiotherapy were evaluated according to the American Cancer Radiotherapy Collaboration (RTOG) acute radiation injury evaluation criteria, and the above adverse reactions ≥ grade 3 were treated as the severity. Olink proteomics technology was used to detect the level of 92 inflammatory cytokines (the standardized protein expression values) in the plasma of patients before radiotherapy for the first time. Single factor analysis of variance and independent sample t-test were used to analyze the relationship between inflammatory cytokines and clinical factors, as well as acute adverse reactions during radiotherapy. Based on inflammatory cytokines and/or the clinical factors, binary logistic regression was used to construct a predictive model for the risk of severe acute radiotherapy adverse reactions. Whether the most severe adverse reactions assessed by the American RTOG acute radiation injury evaluation criteria during radiotherapy were severe or not were taken as the gold standard. Receiver operating characteristic (ROC) curve was used to analyze the effectiveness of the established models for judging the severe acute adverse reactions. Results:Among the 85 patients, 68 were males and 17 were females, with the median age [ M ( Q1, Q3)] of 49 years (43 years, 60 years). All patients received radical radiotherapy, of which 64 cases were treated with combination chemotherapy or targeted therapy. A total of 19 cases (22.1%) experienced severe acute radiotherapy adverse reactions. There were statistically significant differences in the levels of interleukin (IL)-22 receptor A1 (IL-22RA1), IL-18 receptor 1(IL-18R1), eotaxin-1 (CCL11), tumor necrosis factor ligand superfamily member 14 (TNFSF14), FMS-like tyrosine kinase 3 ligand (Flt3L), and monocyte chemotactic protein 2 (MCP-2) in the plasma of patients with grade 1, 2, 3 acute radiation oral mucositis before radiotherapy; there were statistically significant differences in the levels of CD244 (all P < 0.05); there were statistically significant differences in the levels of CD244, CC chemokines ligand 20 (CCL20), leukemia inhibitory factor ligand (LIF-R) and IL-4 in the plasma of patients with grade 1, 2, 3 acute radiation dermatitis before radiotherapy (all P < 0.05); there were statistically significant differences in the levels of IL-12B, CXC chemokines ligand 11 (CCL11), LIF-R and IL-33 in the plasma between patients with grade 1 and grade 2 xerostomia before radiotherapy (all P<0.05). The result of single factor analysis of variance showed that the clinical factors were not associated with severe acute radiation adverse reactions (all P > 0.05). Binary logistic regression model M1 was established by selecting 6 clinical factors including age, T staging, N staging, clinical staging, whether to receive chemotherapy or not and whether to suffer from diabetes or not in the literatures. Based on cytokine function and previous literatures, the binary logistic regression model M2 was established by selecting IL-22RA1, IL-18R1, MCP-2, CCL11, CD244, CCL20 and IL-33 from the differential cytokines. A binary logistic regression model M3 was established by combining the above clinical factors with cytokines. The ROC curve analysis showed that the area under the curve of the M1, M2, M3 predictive models for judging the severe acute radiation adverse reactions was 0.781, 0.841, 0.868, respectively. Conclusions:There were differences in the expression levels of various inflammatory cytokines in plasma before radiotherapy among patients with different grades of acute radiotherapy adverse reactions. Building the models based on plasma inflammatory cytokine levels combined with clinical factors before the first radiotherapy could effectively predict the risk of severe acute radiotherapy adverse reactions in patients with nasopharyngeal carcinoma.

Objective:To study the experience and efficacy of treating the isolated left vertebral artery (ILVA) during total aortic arch replacement combined with stent-trunk surgery in patients with Stanford type A aortic dissection (TAAD) combined with ILVA.Methods:The clinical data of 21 patients with TAAD combined with ILVA from July 2017 to March 2022 in the First Affiliated Hospital of University of Science and Technology of China were retrospectively analyzed. All patients were treated with ILVA-left common carotid artery transplantation and total arch replacement combined with stent-trunk surgery under moderate hypothermia cardiopulmonary bypass and selective cerebral perfusion (SCP). Among them, aortic root repair surgery was in 15 cases, Bentall surgery in 6 cases, coronary artery bypass grafting performed simultaneously in 2 cases. The surgical details, postoperative complications and length of stay were recorded. The patients were followed up 1 and 12 months after surgery for CTA examination to observe the patency of transplanted ILVA. The follow-up was performed until October 1, 2022, and survival, aorta-related death and ILVA patency rate were recorded.Results:Three hundred and thirty-five TAAD patients were admitted during the same period, including 21 (6.27%) with ILVA. ILVA was reconstructed successfully in all patients. No complications related to ILVA were observed. Three cases died during the perioperative period: 1 case had preoperative myocardial infarction due to coronary artery involvement and the CPB could not be removed after operation; 1 case died of postoperative liver and renal failure due to severe organ hypoperfusion; 1 case suffered from postoperative acute renal failure and died of low cardiac output. The patients did not experience damage to the vagus nerve or recurrent laryngeal nerve, lymphatic leakage, chylothorax, ILVA thrombosis, paraplegia or cerebral vascular complications. The other 18 patients recovered and discharged from hospital. The median duration of follow-up was 30 (6 to 62) months. During the follow-up, aortic-related death did not observe, ILVA was unobstructed, and there were no manifestations of anastomotic stenosis or arterial stenosis.Conclusions:ILVA is a supra-aortic trunk variant, it is not so rare. ILVA may pose additional difficulties during total arch replacement surgery. The clinical effect of prior reconstruction of ILVA by ILVA-LCCA transposition is satisfactory, and it may be a simple and efficient method to complete reconstruction and optimize arch surgery before cardiopulmonary bypass.
