Age-related macular degeneration(ARMD)is a progressive visual impairment fundus disease that frequently occurs in individuals aged >55 years. The main risk factors are aging, long-term smoking, genetics, and racial differences. Pathogenesis includes abnormal function of the retinal pigment epithelium, damaged blood-retinal barrier, and abnormal immune function. Currently, intravitreal injection(IVI)of anti-vascular endothelial growth factor(VEGF)drugs is the preferred treatment option for ARMD in clinical practice. However, it also faces challenges such as repeated treatments, high medical costs, and poor patient compliance. The predicament in the treatment of ARMD has given rise to several new treatment options. This article aims to review the treatment methods and progress of dry ARMD and wet ARMD, providing new ideas for addressing the limitations of the current clinical anti-VEGF treatment.

Cervical cancer is one of the most common gynecological malignant tumors in China. Given their lack of obviously early symptoms, more than half of patients with cervical cancer are diagnosed in the middle and late stages of this malignancy, resulting in poor prognosis. Finding new therapeutic targets is the current research direction. Metabolomics, as a new omics technology, is expected to provide new targets for tumor precision diagnosis and treatment through the analysis of the changes and potential mechanisms of metabolites in tumor occurrence and development by chromatography, mass spectrometry, and other technologies. Herein, we review the research methods of metabolomics; metabolic characteristics of cervical cancer; and progress of the research on metabolomics in cervical cancer diagnosis, curative effect prediction, and prognosis evaluation to provide new ideas for the precise diagnosis and treatment of cervical cancer.

ObjectiveTo investigate the effect and molecular mechanism of exosomes derived from bone marrow mesenchymal stem cells（BMSC-exos） modified with Bushen Yisui capsule（BSYS）-containing serum on promoting the differentiation and maturation of OLN-93 oligodendrocytes by regulating miR-15b/Wnt signaling pathway. MethodsOLN-93 cells were divided into 5 groups， including the normal（NC） group， BMSC-exos group， BSYS-BMSC-exos group， BSYS-BMSC+LV-miR-15b-5p inhibitor-exos group， and BSYS-BMSC+LV-miR-15b-5p NC-exos group. DiR staining was used to observe the uptake of Exos by OLN-93 cells. The effective dosage of BSYS-BMSC-exos on OLN-93 cells was assessed by cell proliferation and activity assay（CCK-8）. Stable BMSCs lentiviral transfection strains were established to inhibit miR-15b-5p expression in both BMSCs and their exos， and transfection efficiency was verified by real-time fluorescent quantitative polymerase chain reaction（Real-time PCR） detection of miR-15b-5p. The expressions of 2′，3′-cyclic nucleotide 3′-phosphodiesterase（CNPase） and myelin proteolipid protein（PLP） in OLN-93 cells were detected by immunocytochemistry（ICC） and Western blot. The mRNA expressions of miR-15b-5p and Wnt3a in OLN-93 cells were detected by Real-time PCR， and the protein expression of Wnt3a was measured by Western blot. The expression levels of key molecules in the Wnt/β-catenin signaling pathway of OLN-93 cells， including glycogen synthase kinase（GSK）-3β， β-catenin， and T-cell specific transcription factor 4/transcription factor 7-like 2（TCF4/TCF7L2）， were measured by Real-time PCR and Western blot. ResultsDiR-labeled Exos were efficiently taken up by OLN-93 cells. The CCK-8 assay results indicated that 20 mg·L^-1 of BSYS-BMSC-exos exhibited the most significant effect in enhancing OLN-93 cell viability（P<0.01） and this dosage was selected for subsequent experiments. Following lentiviral transfection of BMSCs， Real-time PCR results revealed that miR-15b-5p was significantly suppressed in BMSCs（P<0.01）， and miR-15b-5p was also notably inhibited in BSYS-BMSC-exos（P<0.01）. ICC analysis further revealed an increase in the number of differentiated， mature CNPase and PLP-positive cells following BSYS-BMSC-exos treatment（P<0.01）. Western blot results demonstrated that the protein expression of CNPase and PLP was significantly enhanced with BSYS-BMSC-exos treatment（P<0.01）. Additionally， BSYS-BMSC-exos also increased the expression levels of miR-15b-5p and p-β-catenin proteins in OLN-93 cells， while decreased the mRNA and protein expressions of Wnt3a， as well as the mRNA expressions of β-catenin and TCF4/TCF7L2， and the protein expression level of p-GSK-3β（Ser9） was significantly reduced（P<0.05， P<0.01）. After the transfection of miR-15b-5p inhibitor into BSYS-BMSC-exos， the above effects were significantly diminished（P<0.05， P<0.01）. ConclusionBSYS-BMSC-exos facilitate the differentiation and maturation of OLN-93 cells， and its mechanism is related to the upregulation of miR-15b-5p in OLN-93 cells， which inhibits the expression of Wnt3a and thereby suppresses the Wnt signaling pathway.

The results of immune infiltration analysis showed that various immune cells were closely related to the biological processes of rheumatoid arthritis, including γδ T cells, monocytes, regulatory T cells, CD8 T cells, etc. Saposheikovize Radix, Cinnamomi Ramulus, Anemarrhenae Rhizoma, Dendrobii Caulis, Rehmannine Radix, Lonicerae Japonicae Flos, Pinelliae Rhizoma, Cimicifugae Rhizoma, Poria, Stephaniae Tetrandrae Radix were the 10 kinds of commonly used key Chinese materia medica in the treatment of RA.Conclusions:Acupuncture and moxibustion may treat RA by regulating RHOA, JAK1, FYN, LCK and other core targets. This study predicts that Chinese materia medica can be used as a source of drugs for the treatment of RA, and can provide new ideas for the combination of acupuncture and medicine for the treatment of RA.

Heat stroke (HS), also known as severe sunstroke, is one of the most serious heat-related disorders, characterized by rapid onset, rapid progression, aggressive condition, and high morbidity and mortality. The occurrence and development of HS are closely related to pathophysiological processes such as inflammation, oxidative stress, cell death, and coagulation failure. With the gradual discovery of the pathogenic mechanisms of HS, some drugs or therapeutic approaches targeting its molecular regulatory pathways have shown clinical promise. This review intends to provide an overview of research advances in HS types, pathogenic mechanisms, preclinical and clinically relevant therapeutic strategies, as well as to highlight the potential clinical applications of HS-related biomarkers and therapeutic targets with a view to informing the clinical management of HS.
