This article systematically reviews and verifies the historical evolution of Stemonae Radix from the aspects of name， origin， harvesting and processing， quality and others by consulting ancient and modern literature， in order to provide reference for the development and utilization of famous classical formulas containing this medicinal herb. Stemonae Radix has a long history of application， and it derives its name from its distinctive growth pattern， featuring clusters of ten to several dozen underground tuberous roots. This morphology resembles that of certain plants in the genus Asparagus， leading to historical instances where tuberous roots from genus Asparagus were mistakenly used as Stemonae Radix. After the research， it can be concluded that Stemonae Radix was first recorded in Mingyi Bielu， and throughout history， Baidu has been recognized as its official name， though it also bears alternative names such as Baibing， Pofucao and Ye Tianmendong. The mainstream sources used throughout history have been the dried tuberous roots of Stemona sessilifolia， S. japonica or S. tuberosa from the family Stemonaceae. This aligns with the 2025 edition of Pharmacopoeia of the People's Republic of China（hereinafter referred to as Chinese Pharmacopoeia）. Additionally， Asparagus filicinus and A. officinalis from the genus Asparagus are common sources of confusion with Stemonae Radix. The three primitive plants are mainly distributed in the Yangtze River basin and southern China， exhibiting a wide distribution. Historically， wild harvesting was predominant， but cultivation is now established. In ancient times， the harvesting time was mostly in the second， third， and eighth lunar months， when roots were harvested and dried. Nowadays， it is more common to pick and excavate in the spring and autumn seasons. After excavation， the roots are washed， fibrous roots removed， briefly blanched in boiling water or steamed until no white core remains， and then sun-dried or oven-dried. In ancient times， the processing of Stemonae Radix primarily involved roasting（stir-frying）， wine roasting， or raw materials. Modern mainstream processing specifications include two types of raw and honey-roasted products. In terms of quality evaluation of the medicinal materials， ancient criteria of "preferring plump and moist roots" align with modern requirement favoring "thick， robust stems with firm texture". Evaluating quality with authenticity， since the Song dynasty， it has been highly praised to produce in Chuzhou and Hengyang as the best. It was an ancient method of fixing the production area to stabilize the medicinal origin， reflecting the ancient recognition of the therapeutic efficacy of plants belonging to the genus Stemona. The main functions of Stemonae Radix remain consistent throughout history， including relieving coughs， eliminating phlegm and parasites. Based on the research results， it is recommended that when developing famous classical formulas containing the medicinal material Stemonae Radix， the botanical source specified in the 2025 edition of Chinese Pharmacopoeia should be selected. The specific species can be determined according to the distribution of resources and the main production areas， and the origin and corresponding botanical source should be fixed. Processing methods should be chosen based on the prescription requirements. It is recommended to use raw products without specified requirements.

Objective To investigate the effects of probiotics combined with dietary intervention on pe-ripheral blood glucose and lipid metabolism indicators,placental tissue insulin signaling pathway proteins ex-pression and pregnant outcome in the patients with gestational diabetes mellitus(GDM).Methods A total of 83 patients with GDM in this hospital from December 2021 to December 2022 were selected as the study sub-jects and divided into the probiotics group(probiotics combined with diet intervention,43 cases)and control group(simple diet intervention,40 cases)by the random number table method.The levels of peripheral blood glucose,lipid and insulin resistance related indicators before the intervention and in 8 weeks after the interven-tion were compared between the two groups.The histological changes of placenta were observed by HE stai-ning.The pathological indicators were compared between the two groups.The expression levels of insulin re-ceptor substrate-1(IRS-1),glucose transporter 4(GLUT4)and synaptosome-associated protein of 23 kDa(SNAP23)in placental tissue were detected by immunohistochemistry.The pregnant adverse outcomes were compared between the two groups,and the clinical efficacy of probiotics was evaluated.Results Compared with the control group,the levels of fasting blood glucose(FBG),fasting insulin(FINS),serum triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)in 8 weeks after intervention in the probiotics group were significantly decreased(P＜0.05),and the level of serum high density lipoprotein cholesterol(HDL-C)was significantly increased(P＜0.05).There were no significant differences in the incidence rates of poor villi maturation,thickening of dry villi arterioles and capillary filling in villi interstitial between the two groups(P＞0.05).Compared with the control group,the expression levels of IRS-1,GLUT4 and SNAP23 in placen-tal tissue of the probiotics group were significantly increased(P＜0.05).The incidence rates of neonatal hy-poglycemia and neonatal hyperbilirubinemia in the probiotics group were significantly lower than those in the control group(P＜0.05).Conclusion Compared with simple dietary intervention,probiotics combined with dietary intervention has more advantages in improving glucose and lipid metabolism of GDM patients,moreo-ver reduces the adverse events occurrence in newborns.

OBJECTIVE To analyze the distribution characteristics of warfarin drug-gene polymorphism in Han children from Beijing area. METHODS Data of nine warfarin drug-gene loci about VKORC1 rs9923231， CYP2C9 rs1799853*2 and rs1057910*3， CYP4F2 rs2108622， APOE rs429358 and rs7412， ABCB1 rs1045642， EPHX1 rs1051740 and rs2234922 were collected from dept. of cardiovascular medicine， Children’s Hospital Affiliated to Capital Institute of Pediatrics from March 2019 to March 2023， and the population data reported in domestic and foreign literature were compared. RESULTS In Beijing area， the frequency of APOE rs429358 mutant genotype was higher in males （19.8%） than in females （13.5%）（P＜0.05）. VKORC1 rs9923231 was dominated by homozygous mutant genotype （83.3%）， which was consistent with children in Japan （82.2%）， and higher than that of predominantly Caucasian children in the UK， Sweden， the United States， and Germany （10.4%-18.3%）（P＜ 0.05）； CYP2C9 was dominated by *1/*1 type （91.9%）， which was consistent with children in Japan （94.6%）， and higher than that of predominantly Caucasian children in the UK， Sweden， the United States， and Germany （66.1%-73.4%）（P＜0.05）. The frequency of EPHX1 rs1051740 mutant genotype was higher in adults （78.5%） than in children （63.5%）（P＜0.05）. CONCLUSIONS More mutations of VKORC1 rs9923231 and ABCB1 rs1045642 are found in Han children from Beijing area. The distribution of warfarin drug-gene polymorphisms in Han children from Beijing area is different among different genders， as well as compared with other countries， and Chinese Han adults. Therefore， caution should be exercised when using the reported data.

Objective To investigate the effect of dexmedetomidine(Dex)on the release of glial cell line-derived neurotrophic factor(GDNF)during the anti-ischemic stroke.Methods SD rats were randomly divided into sham group(Sham group),sham+dexmedetomidine group(Sham+Dex group),ischemic stroke group(IS group),ischemic stroke+dexmedetomidine group(IS+Dex group),ischemic stroke+dexmedetomidine group+anti-GDNF(IS+Dex+anti-GDNF group),with 15 rats in each group.IS model was established by Longa's methods.24 hours later,the neurological scores were evaluated.Then,the rats were sacrificed and the cerebral spinal fluid,as well as the peripheral blood,were collected to detect the content of GDNF.In addition,TTC staining was used to evaluate the area of cerebral ischemic infarction,and immunofluorescence was applied to detect the activation of astrocytes.Furthermore,the activation phenotype of astrocytes was detected by qRT-PCR.Results Compared with Sham group,there were no significant changes in all indexes of rats in Sham+Dex group.In IS group,the neurological score increased(P＜0.05),the local infarction area appeared,the release of GDNF in peripheral and central system increased(P＜0.05),and the microglia activation was induced by IS,and the expression of neuro-toxic and neuroprotective phenotype genes increased significantly(P＜0.05).Compared with the IS group,the neurological function score of the rats in the IS+Dex group significantly decreased(P＜0.05),the local infarct area was significantly reduced(P＜0.05),and the release of GDNF further increased(P＜0.05).The expression of neurotoxic astrocyte phenotype genes significantly decreased(P＜0.05),while the expression of neuroprotective astrocyte phenotype genes further increased(P＜0.05).However,intervention with anti-GDNF antibody obviously reversed the therapeutic effect of Dex compared with the IS+Dex group.Conclusion Dex can inhibit the pheno-type of neurotoxic astrocytes,increase the proportion of neuroprotective astrocytes,further promote the release of GDNF,and play an anti-ischemic stroke role.

Alzheimer disease is the most common neurodegenerative disease characterized by cognitive impairment,mental and behavioral disorders,and decreased social functioning.The current mainstream therapeutic drugs,cholinester-ase inhibitors and N-methyl-D-aspartate receptor antagonists,mainly focus on improving cognitive function.The advance-ment in the development of novel therapeutics for the etiology has been sluggish,and there exists a paucity of drug options available.As a novel cognitive intervention approach,cognitive training has received increasing attention in the treatment of Alzheimer disease due to its ability to enhance cognition,improve daily living skills,and regulate emotions by bolstering cognitive reserve and promoting neuroplasticity.This article reviews the clinical research and application of cognitive train-ing in Alzheimer disease,aiming to provide reference for rational application of cognitive training in Alzheimer disease.

Objective To compare and explore the differences between the eight batches of drugs in the centralized procurement list and the 2018 edition of the national essential medicine list,and to provide reference for updating and improving the national essential medicine list and the national centralized procurement list of drugs.Methods The category,generic name variety,specification,and other information of drugs included in the centralized drug procurement were collected and compared with the 2018 edition of the national essential medicine list,and the reasons for differences were analyzed.Results A proportion of 39%of centralized procurement drugs were listed in national essential medicines.Forty pharmacological classifications were not involved in the drugs of centralized procurement.Only anticoagulant and thrombolytic drugs with dual attributes accounted for a smaller variety proportion than the specification proportion.Conclusion There are some differences between the centralized procurement list and the 2018 edition of the national essential medicine list,which have some rationality,but also some problems to be solved.

Virus-like particles(VLPs)are nanoparticles that are self-assembled from one or more structural proteins,which can be arranged in several layers or contain a lipid outer membrane.Due to the lack of genetic material,VLPs cannot infect host cells,but are highly immunogenic and can induce immune responses different from conventional inactivated vaccines.VLPs can be produced using a variety of systems including bacterial,yeast,plant,insect and mammalian cells.Compared with traditional vaccines,VLPs have incomparable advantages,so they are becoming more and more popular in the biomedical field.To date,a series of vaccine candi-dates based on VLPs have been developed for immunization and prevention of various infectious diseases.At the same time,the recent successful application of VLPs in targeted drug delivery and gene therapy has attracted attention.This paper mainly reviews the com-monly used expression systems of VLPs and the research progress of their applications.

Active immunotherapy for cancer aims to treat disease by inducing effective cellular immunity and humoral immunity.Research on virus-like particles(VLPs)vaccines has made tremendous progress in recent years,dramatically reducing morbidity and mortality from some infectious diseases.VLPs are nanoparticles self-assembled from one or more structural proteins,with highly ordered repeat sequences and good immunogenicity,which can induce strong cellular immune and humoral immune responses.VLPs can overcome immunosuppressive state of tumor microenvironment,break self-tolerance,and trigger strong cytotoxic T lymphocyte activity,which is critical for both viral clearance and destruction of cancer cells.This article mainly reviews current research progress of VLPs-based cancer vaccines and potential defects of VLPs as vaccine carriers in development of cancer vaccines.
