Diminished ovarian reserve (DOR) is a major cause of female infertility, characterized by a complex and multifactorial etiology involving aging, genetic predisposition, environmental factors, and immune mechanisms. Therapeutic options for DOR remain limited, with no currently established treatments demonstrating consistently robust efficacy. Recent advances in regenerative medicine—including the use of mesenchymal stem cells and their derivatives, platelet-rich plasma and in vitro activation—have opened promising new avenues for ovarian function restoration. This review offers a comprehensive summary of research progress in DOR treatment over the past five years, covering hormonal therapies, assisted reproductive technologies, nutritional supplementation and lifestyle modifications, Traditional Chinese Medicine, targeted therapies, and regenerative medicine approaches, with the aim of providing guidance for clinical management of DOR.

Tumor-targeted therapy is a vital approach in precision medicine,selection of target molecule is a key element in tumor-targeted therapy.B7-H3(CD276),as an immune checkpoint molecule selectively highly expressed on tumor cells,is a crucial molecule involved in regulation of tumor immunity.Numerous recent studies have found that B7-H3,in addition to its immune check-point function,also participates in regulation of malignant biological behaviors of tumor cells and is considered to have great potential as a pan-cancer universal drug target.Current immunotherapeutic strategies targeting B7-H3 primarily include development of block-ing monoclonal antibodies(Blocking mAb),antibody-drug conjugate(ADC),chimeric antigen receptor(CAR)T/NK cell therapies,monoclonal antibody dependent cellular cytotoxicity(ADCC)drugs,radionuclide drug conjugates(RDC),bispecific/trispecific anti-body(BsAb/TriAb),and antibody cytokine drug combinations,among others.These strategies aim to enhance body's immune re-sponse to cancer through various mechanisms,thereby inhibiting tumor growth and metastasis.Multiple preclinical and clinical studies have shown that immunotherapy targeting B7-H3 has potential therapeutic value.Therefore,this article mainly reviews the latest status of development of tumor immunotherapy drugs targeting B7-H3 molecule.

Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

[Objective] To study on the genotyping of a sample with inconsistent forward and reverse serological tests, and to conduct a pedigree investigation and molecular biological mechanism study. [Methods] The ABO blood group of the proband and his family members were identified using blood group serological method. The ABO gene exon 1-7 of samples of the proband and his family were sequenced by Sanger and single molecule real-time sequencing (SMRT). DeepTMHMM was used to predict and analyze the transmembrane region of proteins before and after mutation. [Results] The proband and his mother have the Bw phenotype, while his maternal grandfather has ABw phenotype. The blood group results of forward and reverse typing of other family members were consistent. ABO gene sequencing results showed that there was B new mutation of c.3 G>C in exon 1 of ABO gene in the proband, his mother and grandfather, leading to a shift in translation start site. DeepTMHMM analysis indicated that the shift in the translation start site altered the protein topology. [Conclusion] The c.3G>C mutation in the first exon of the ABO gene leads to a shift in the translation start site, altering the protein topology from an α-transmembrane region to a spherical signaling peptide, reducing enzyme activity and resulting in the Bw serological phenotype.

The differences in chemical quality characteristics between Xinjiang Rehmannia glutinosa and R. glutinosa were analyzed to provide a theoretical basis for the introduction and quality control of R. glutinosa. In this study, the high performance liquid chromatography(HPLC) fingerprints of 6 batches of Xinjiang R. glutinosa and 10 batches of R. glutinosa samples were established. The content of iridoid glycosides, phenylethanoid glycosides, monosaccharides, oligosaccharides, and polysaccharides in Xinjiang R. glutinosa and R. glutinosa was determined by high performance liquid chromatography-diode array detection(HPLC-DAD), high performance liquid chromatography-evaporative light scattering detection(HPLC-ELSD), and ultraviolet-visible spectroscopy(UV-Vis). The determination results were analyzed with by chemical pattern recognition and entropy weight TOPSIS method. The results showed that there were 19 common peaks in the HPLC fingerprints of the 16 batches of R. glutinosa, and catalpol, aucubin, rehmannioside D, rehmannioside A, hydroxytyrosol, leonuride, salidroside, cistanoside A, and verbascoside were identified. Hierarchical cluster analysis(HCA) and principal component analysis(PCA) showed that Qinyang R. glutinosa, Mengzhou R. glutinosa, and Xinjiang R. glutinosa were grouped into three different categories, and eight common components causing the chemical quality difference between Xinjiang R. glutinosa and R. glutinosa in Mengzhou and Qinyang of Henan province were screened out by orthogonal partial least squares discriminant analysis(OPLS-DA). The results of content determination showed that there were glucose, sucrose, raffinose, stachyose, polysaccharides, and nine glycosides in Xinjiang R. glutinosa and R. glutinosa samples, and the content of catalpol, rehmannioside A, leonuride, cistanoside A, verbascoside, sucrose, and glucose was significantly different between Xinjiang R. glutinosa and R. glutinosa. The analysis with entropy weight TOPSIS method showed that the comprehensive quality of R. glutinosa in Mengzhou and Qinyang of Henan province was better than that of Xinjiang R. glutinosa. In conclusion, the types of main chemical components of R. glutinosa and Xinjiang R. glutinosa were the same, but their content was different. The chemical quality of R. glutinosa was better than Xinjiang R. glutinosa, and other components in R. glutinosa from two producing areas and their effects need further study.

Objective To investigate the effect of Gd-hydroxyapatite(Gd-HA)stents with adipose mesenchymal cells(ADSCs)on the repair of knee articular cartilage defects.Methods To isolate,culture,and identify rabbit ADSCs by establishing a rabbit knee joint full-thickness cartilage defect model,a total of 18 rabbits were randomly divided into blank control group,Gd-HA scaffold group,and ADSCs+Gd-HA scaffold group.At week 12 and 24 after surgery,International Curtilage Repair Society(ICRS)score,HE,toluidine blue,modified red O bright green and ColⅡ were detected by immunohistochemical staining,then ColⅡand GAG mRNA expression levels were detected by O'Driscoll and Real-time PCR.ColⅡ protein expression was detected by Western blotting,GAG content was detected by DMMB,biomechanical strength was detected by indentation test,and PKH26 labeled ADSCs was used to trace the tissue engineering scaffold with Gd-HA composite ADSCs to evaluate the repair effect of rabbit knee cartilage defects.Results The ADSCs isolated and cultured in vitro showed good growth,stable phenotype and good directional differentiation through macroscopic observation and histological staining,it could be seen that the repair degree and effect of the knee joint full-thickness cartilage defect model implanted with Gd-HA scaffold group were better than those of the blank control group,while the cartilage repair situation of the ADSCs+Gd-HA scaffold group was better than that of the Gd-HA scaffold group(P＜0.05);The ICRS and improved O'Driscoll scores were higher than the other two groups(P＜0.05).Compared with the Gd-HA group,the ADSCs+Gd-HA group could produce ColⅡ and GAG during the process of cartilage repair,with stronger mechanical strength of the repaired tissue(P＜0.05);PKH26 labeled ADSCs were found in the repaired tissues of the ADSCs+Gd-HA group,and they were involved in the composition of newly formed tissues.Conclusion Gd-HA scaffold material combined with ADSCs has a good repair effect on full-thickness cartilage defects in the knee joint as a new type of biological material for repairing joint cartilage defects.

Objective West Nile virus(WNV)is one of the most common mosquito-borne zoonotic viruses worldwide,with unique transmission dynamics and varied hosts.Lots of ecological and host factors have been reported to influence the host adaptation and transmission of WNVs,however,general genomic features of WNVs are less focused,except for some exact host-specific genotypes at molecular level.Artificial intelligence that analyzes genome composition characteristics currently shows significant advantages in identifying and predicting viral host adaptability.This research aimed to establish a convolutional neural network(CNN)model to predict the host adaptability of WNVs based on general genomic features.Methods Presently available WNV gene sequences were embedded for their genomic features with an embedding approach of dinucleotide composition representation(DCR).And DCR-based distribution difference of WNV samples among various hosts was performed with unsupervised learning methods.Then a classification model was built with a convolutional neural network(CNN)framework based on genomic DCR to evaluate the adaptation of the WNVs from birds,mammals and mosquitos.Additionally,host-specific amino acids in WNV proteins were inferred via Bayes method.Results DCR features could effectively distinguish host-specific WNVs.The trained CNN model predicted accurately mammalian susceptible WNVs from avian susceptible WNVs,however,much less accurately for mosquito/mammalian WNVs.Such predicted host adaptation was interpreted as host specified significance of biased amino acid distribution on the bayes-inferred sites in WNV proteins,implying a possible high significance of these sites for WNV adaptive phenotypes.Conclusions Genomic compositional features of WNVs are host-specific,and such genomic bias facilitates predicting the adaptation of WNVs to avian or mammalian hosts via deep learning methods.DCR-based decomposition is helpful to recognize the high risk of infecting mammals of WNVs.The present study provides a general knowledge of genomic features contributing to host adaptation to WNVs.
