According to the principle and current domestic and international construction processes of core outcome set(COS) and the characteristics of post-stroke aphasia, this study built COS with evidence-based support for traditional Chinese medicine(TCM) treatment of post-stroke aphasia. Firstly, a comprehensive review was conducted on the articles about the TCM treatment of post-stroke aphasia that were published in the four major Chinese databases, three major English databases, and three clinical registration centers over the past five years. The articles were analyzed and summarized, on the basis of which the main part of the COS for clinical research on the TCM treatment of post-stroke aphasia was formed. Secondly, clinical doctors and related nursing personnel were interviewed, and important outcome indicators in the clinical diagnosis and treatment process were supplemented to form a pool of core outcome indicators. Two rounds of Delphi surveys were carried out to score the importance of the core outcome indicators in the pool. Finally, a consensus meeting of experts was held to establish the COS for clinical research on the TCM treatment of post-stroke aphasia. The final COS included a total of 268 studies [236 randomized controlled trials(RCTs), 21 Meta-analysis, and 11 clinical registration protocols] and 20 open questionnaire survey results. After two rounds of Delphi surveys, a total of 14 outcome indicators and their corresponding measurement tools were included in the expert consensus meeting. The final expert consensus meeting determined the COS for post-stroke aphasia, which included 9 indicator domains and 12 outcome indicators.

OBJECTIVE: To reveal the effects and potential mechanisms by which synaptic vesicle glycoprotein 2A (SV2A) influences the distribution of amyloid precursor protein (APP) in the trans-Golgi network (TGN), endolysosomal system, and cell membranes and to reveal the effects of SV2A on APP amyloid degradation. METHODS: Colocalization analysis of APP with specific tagged proteins in the TGN, ensolysosomal system, and cell membrane was performed to explore the effects of SV2A on the intracellular transport of APP. APP, β-site amyloid precursor protein cleaving enzyme 1 (BACE1) expressions, and APP cleavage products levels were investigated to observe the effects of SV2A on APP amyloidogenic processing. RESULTS: APP localization was reduced in the TGN, early endosomes, late endosomes, and lysosomes, whereas it was increased in the recycling endosomes and cell membrane of SV2A-overexpressed neurons. Moreover, Arl5b (ADP-ribosylation factor 5b), a protein responsible for transporting APP from the TGN to early endosomes, was upregulated by SV2A. SV2A overexpression also decreased APP transport from the cell membrane to early endosomes by downregulating APP endocytosis. In addition, products of APP amyloid degradation, including sAPPβ, Aβ _1-42, and Aβ _1-40, were decreased in SV2A-overexpressed cells. CONCLUSION These results demonstrated that SV2A promotes APP transport from the TGN to early endosomes by upregulating Arl5b and promoting APP transport from early endosomes to recycling endosomes-cell membrane pathway, which slows APP amyloid degradation.

Objective:To investigate the reparative effects and underlying mechanisms of human umbilical cord mesenchymal stem cells (hUCMSCs) in conjunction with hyperbaric oxygen (HBO) on ovarian dysfunction in mice exposed to simulated high-altitude conditions.Methods:A total of 64 six-week-old female C57BL/6 mice were randomly allocated according to random number table, assigned to control group, model group, hUCMSCs group and hUCMSCs+HBO group, with 16 mice in each group. Mice in model group, hUCMSCs group and hUCMSCs+HBO group were placed in a hypobaric oxygen chamber to simulate a high-altitude environment at an elevation of 6 500 m for 15 d, thereby establishing a model of ovarian dysfunction. Beginning on the first day following model establishment, the control and model groups received intravenous injections of 0.2 mL saline via the tail vein. In contrast, the hUCMSCs group and the hUCMSCs+HBO group received 0.2 mL hUCMSCs (1×10 6 cells) per mouse through tail vein injection, administered once a week for three weeks, with continuous intervention lasting 15 d. Furthermore, the hUCMSCs+HBO group were subjected to daily hyperbaric oxygen treatment. The recorded variables included general health status, body weight, estrous cycle changes, serum hormone levels, bilateral ovarian wet weight, ovarian index, follicular development assessment, pathological alterations of ovarian tissue, ultrastructural changes, and the expression levels of transforming growth factor beta 1 (TGF-β1) and Smad family member 3 (Smad3) detected by Western blotting in ovarian tissue. Additionally, litter size and offspring body weight were measured across all groups to evaluate the reproductive capacity of the mice. Results:1) Compared with the hUCMSCs group, the hUCMSCs+HBO group exhibited no statistically significant differences in estrous cycle, body weight, bilateral ovarian wet weight, or ovarian index (all P>0.05). Furthermore, serum levels of anti-Müllerian hormone (AMH), estradiol, progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH), as well as counts of various stages of follicles in hUCMSCs+HBO group, did not demonstrate statistically significant differences compared with hUCMSCs group (all P>0.05). Notably, in the hUCMSCs+HBO group, the integrity of the nuclear membrane in granulosa cells of the ovarian tissue was preserved, with only mild swelling observed in individual mitochondria, while no expansion of the rough endoplasmic reticulum or swelling of the Golgi apparatus were noted. Additionally, expression levels of TGF-β1 and Smad3 proteins in the hUCMSCs+HBO group were significantly elevated compared with the hUCMSCs group ( P=0.010, P<0.001). The conditions of the offspring and litter size showed no statistically significant differences between the two groups (all P>0.05). 2)Compared with control group, the hUCMSCs+HBO group had slightly lower values for body weight, bilateral ovarian wet weight, ovarian index, serum levels of AMH, estradiol, and progesterone, while had slightly higher serum levels of FSH and LH without statistically significant differences (all P>0.05). Importantly, the ultrastructural characteristics of granulosa cells in the ovarian tissue of the hUCMSCs+HBO group closely resembled those of control group, displaying intact structures of the nuclear membrane, mitochondria, rough endoplasmic reticulum, and Golgi apparatus. There was no significant difference in TGF-β1 protein level between hUCMSCs+HBO group and control group ( P=0.253), but Smad3 protein level in hUCMSCs+HBO group was higher than that in control group ( P<0.001). No statistically significant differences were detected in offspring body weight, litter size, or behavioral tendencies (all P>0.05). Conclusion:Both hUCMSCs and the combination of hUCMSCs with HBO intervention demonstrated a safe and effective promotion of functional repair in damaged ovarian tissue under hypoxic conditions. Notably, the combination treatment of hUCMSCs with HBO exhibited a synergistic effect compared with hUCMSCs alone. The potential mechanism underlying this enhanced functional repair may involve the upregulation of the TGF-β1/Smad3 signaling pathway, which could ultimately improve fertility outcomes in mice subjected to hypoxic environments.

Vaccines are among the most effec-tive measures for preventing infectious diseases and play a crucial role in controlling the spread of these diseases.Adjuvants,serving as auxiliary com-ponents in vaccines,are indispensable in the vac-cine development process.Ideal adjuvants not only enhance the immune response,enabling the body to achieve optimal protective immunity but also play important roles in reducing the dosage of im-munogens and lowering vaccine production costs.To meet the demands of novel vaccines,many new types of adjuvants have been developed.However,there is still a lack of adjuvants that are safe,effec-tive,easy to prepare,highly pure,and suitable for a variety of vaccines in clinical settings.This article categorizes adjuvants and summarizes their mecha-nisms of action and characteristics,focusing on tra-ditional aluminum salt adjuvants and more modern lipid-based and nucleic acid-based adjuvants.The summary is based on a computer search of data-bases including PubMed,Embase,The Cochrane Li-brary,CNKI(China National Knowledge Infrastruc-ture),VIP Database,and Wanfang Database,using English search keywords such as Adjuvants,Vac-cine,Vaccine Adjuvant,aluminum salts,MF59,AS03,Toll-like receptor agonist,etc.,and corre-sponding Chinese search terms.The aim is to pro-vide references for the development and applica-tion of adjuvants.

The aim of our research was to obtain Listeria bacteriophages from food and related environments,and conduc-ted the analysis of the electron microscopic morphology,host range specificity,and biological characteristics of the purified phages.The double-layer agar method and the spot test were employed for the isolation and identification of a virulent Listeria phage named LMLPA5,with the isolated strain Listeria in-nocua Lin08 as the host.Phage morphology was observed by transmission electron microscope.The biological characteris-tics of the phage were assessed by determining their host range,optimal multiplicity of infection(MOI),one-step growth curve,and physicochemical stability.Additionally,the preservation efficacy of the phage at 4 ℃,-20 ℃,and-80 ℃ was explored.The phage LMLPA5 belongs to the family Myoviridae based on morphology,exhibiting clear and transparent plaques without halo surrounded.Strains of sever-al Listeria species and different serotypes strains of Listeria monocytogenes were susceptible to lysis by LMLPA5,indica-ting its broad-spectrum activity against Listeria monocytogenes.Optimal MOIs and single-step growth curve analyses revealed optimal MOIs of 0.1 and latent period of 10 minutes for LMLPA5,with average burst size at 95.2 PFU/cell.LMLPA5 was sensitive to high temperatures,and completely inactivated after exposure to 70 ℃ for 1 h,while the phage remained stable for over 32 hours ranging from 4 ℃ to 40 ℃.Within the pH range of 4 to 10,phage titer remained stable and completely inactiva-ted until 60 minutes of ultraviolet exposure.LMLPA5 displayed insensitivity to chloroform,confirming its non-enveloped phage morphology.The phages remained stable for over 8 months when store at 4 ℃ and-80 ℃.The biological characteristics and lysis capacity of phage LMLPA5 were elucidated in this study,which provide the basis for further application.
