AIM: To evaluate the postoperative clinical efficacy of non-diffractive extended depth of focus intraocular lens(EDOF IOL)in patients with highly myopic cataract(HMC).METHODS:A retrospective analysis was conducted on the clinical data of patients diagnosed with HMC at the hospital from January 2022 to December 2024. Patients were divided into an observation group [undergoing femtosecond laser-assisted cataract surgery(FLACS)combined with non-diffractive EDOF IOL implantation] and a control group(undergoing FLACS combined with aspheric monofocal IOL implantation)according to the type of implanted IOL. Postoperative visual acuity(LogMAR), visual quality, and patient satisfaction were compared between the two groups.RESULTS: A total of 33 patients(47 eyes)were finally included in this study, including 10 patients(17 eyes)in the observation group and 23 patients(30 eyes)in the control group. The observation group had a median age of 59.0(52.8, 63.8)y, with 8 males(13 eyes)and 2 females(4 eyes). The control group had a median age of 56.0(53.5, 60.0)y, with 13 males(17 eyes)and 10 females(13 eyes). At 3 mo postoperatively, the best-corrected distance visual acuity(BCDVA)was 0.10(0.08, 0.12)in the observation group and 0.20(0.10, 0.40)in the control group(P=0.586). However, the best-corrected intermediate visual acuity(BCIVA)[0.10(0.10, 0.10)vs 0.50(0.40, 0.90), P=0.032] and best-corrected near visual acuity(BCNVA)[0.20(0.18, 0.20)vs 0.60(0.45, 1.45), P=0.044] in the observation group were significantly better than those in the control group. The defocus curve showed that the uncorrected visual acuity(UCVA)in the observation group was relatively stable within the range of -2.00 to +1.00 D, which was superior to that in the control group. Postoperative questionnaires showed that the spectacle independence rate(76%)and overall satisfaction(88%)in the observation group were significantly higher than those in the control group(10% and 60%, respectively).CONCLUSION: Non-diffractive EDOF IOL significantly improves intermediate and near visual acuity, reduces spectacle dependence, and maintains distance visual acuity by extending the depth of focus, providing better postoperative visual quality and life satisfaction for HMC patients.

Since the founding of the People’s Republic of China, remarkable achievements have been gained in infectious disease prevention and control, and rich practical experiences have been accumulated. If these experiences are shared with developing countries, it will greatly contribute to global infectious disease control and global health security. Under the framework of Forum on China-Africa Cooperation, a series of China-Africa public health capacity training programs have been recently held in China, in order to help improve the capability of infectious disease control in African countries. This article summarized and refined good design concepts and practices from these programs, so as to provide insights into sustainable optimization of China-Africa public health capacity training and improvements of the training effectiveness.

BACKGROUND:Postoperative fever is one of the common clinical symptoms after posterior lumbar interbody fusion. There is no clear etiology or pathogenesis. The postoperative body temperature of patients is easy to repeat,the course of the disease is long,and the therapeutic effect of western medicine is poor,which affects the postoperative recovery of patients. OBJECTIVE:To review the relationship between inflammatory signaling pathways and postoperative fever and the mechanism of Chinese medicine inpreventing and treating fever after posterior lumbar interbody fusion,and to explore new therapeutic drugs for postoperative fever.METHODS:The CNKI Chinese Journal full-text database,WanFang database,and PubMed database were searched for articles published from June 2006 to December 2023. Chinese search terms were "Chinese medicine,postoperative fever,inflammation,interleukin-1,interleukin-6,interleukin-8,interferon gamma,tumor necrosis factor,prostaglandin E2,p38 mitogen-activated protein kinase,nuclear factor-κB,Toll-like receptor,Janus kinases/signal transduction and transcriptional activator,Notch signaling pathway." English search terms were "medicinal herb,postoperative fever,inflammation,interleukin-1,interleukin-6,interleukin-8,γ-interferon,tumor necrosis factor,prostaglandin E2,p38 mitogen-activated protein kinase,nuclear factor-κB,toll-like receptor,janus kinases/signal transducer and activator of transcription,notch signaling pathway." Articles with irrelevant research content and poor quality were excluded,and 100 articles were included and summarized.RESULTS AND CONCLUSION:(1) The operation induced the release of inflammatory factors,and the pro-inflammatory factors acted on the thermoregulatory center in the anterior hypothalamus to promote fever. (2) The absorption of bleeding and oozing fluid in the incision after surgery,and the phagocytosis of the egg white decomposition products of the necrotic cells,produce endogenous pyrogen (interleukin,tumor necrosis factor,interferon,etc.),leading to fever. (3) Cytokines pass through inflammatory signals,play an inflammatory role,and promote fever. (4) Chinese herbs or Chinese herbal compounds can regulate inflammatory signaling pathways and play an anti-inflammatory and antipyretic role in preventing and treating postoperative fever. Due to the lack of the mechanism of action of traditional Chinese medicine,it is necessary to further study and clarify the signaling pathways related to the prevention and treatment of postoperative fever by traditional Chinese medicine,and use modern technology to link cellular and molecular technology with the pharmacological mechanism of traditional Chinese medicine,so as to guide clinicians to use medicine and promote postoperative recovery of patients. (5) Chinese medicine combined with Western medicine in the treatment of postoperative fever is a future research hotspot. We should give full play to the advantages of Chinese medicine,and clarify the target mechanism of action of different syndrome types of Chinese medicine monomer or active ingredient extracts and Chinese medicine decoction.

AIM:To investigate the effect of silent information regulator 1(SIRT1)on the degree of aging and apoptosis in a mouse cardiomyocyte aging model through the regulation of Wnt/β-catenin pathway.METHODS:An in vi-tro aging model was established by inducing HL-1 cells with 40 μmol/L D-galactose(D-Gal).The HL-1 cells were trans-fected with a lentivirus overexpressing SIRT1,and the transfection efficiency was verified by Western blot.Western blot was used to detect the protein expression levels of SIRT1,P53,P21,cleaved caspase-3,B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),β-catenin,Wnt3a and c-Myc.Senescence-associated β-galactosidase(SA-β-Gal)staining was used to detect cellular senescence level.MTT colorimetric assay was used to detect the cell viability,and flow cytometry was used to detect the apoptosis.RESULTS:Treatment of HL-1 mouse cardiomyocytes with D-Gal led to in-creases in the expression levels of aging-related proteins P53 and P21,as well as an increase in SIRT1 protein level.Addi-tionally,the SA-β-Gal staining showed a significant increase in the positive area(P＜0.05).The expression levels of apop-tosis-related proteins cleaved caspase-3 and Bax were elevated,while the level of the anti-apoptotic protein Bcl-2 was re-duced(P＜0.05).There was a marked decrease in cell viability(P＜0.05),and flow cytometry analysis demonstrated a significant increase in cell apoptosis rate(P＜0.05),which was positively correlated with the duration of D-Gal treatment.Overexpression of SIRT1 notably reduced both aging and apoptosis levels after 48 h of D-Gal treatment(P＜0.05).After D-Gal treatment,the expression levels of β-catenin,c-Myc and Wnt3a proteins were up-regulated.However,these levels were reduced when SIRT1 was overexpressed.Moreover,the addition of LiCl,a Wnt/β-catenin pathway agonist,resulted in increased expression levels of β-catenin,c-Myc and Wnt3a proteins compared with the group with SIRT1 overexpres-sion and D-Gal treatment(P＜0.05).CONCLUSION:SIRT1 inhibits cardiomyocyte apoptosis and alleviates cardiomyo-cyte aging through the Wnt/β-catenin pathway.

Objective:To explore the effectiveness of digital management platform led by outpatient specialist nurses among patients with type 2 diabetes in outpatient settings.Methods:From March 2024 to March 2025, adult patients with type 2 diabetes who visited the Endocrinology Clinic at Peking Union Medical College Hospital were selected using convenience sampling. Patients were randomly assigned to the control group and intervention group using the random number table method. Patients in control group received routine education on type 2 diabetes during their clinic visits after enrollment. Intervention group was managed by nurses through a digital management platform, establishing long-term connections with patients. Based on the platform, nurses regularly provided patients with knowledge updates, promptly responded to patient inquiries, reviewed daily dietary records, monitored blood glucose data, conducted weekly telephone follow-ups, and scheduled regular clinic visits to precisely intervene in patients' lifestyles. The glycated hemoglobin (HbA1c) and self-management behavior scores were compared between two groups of patients before and after three months of intervention.Results:A total of 46 patients were enrolled and completed the 3-month follow-up, including 25 in control group and 21 in intervention group. There were no statistically significant differences in HbA1c or self-management behavior scores between the two groups of patients before intervention ( P>0.05). At three months of intervention, the HbA1c reduction in intervention group was greater than that in control group, with a statistically significant difference ( P<0.05). There was no statistically significant difference in Summary of Diabetes Self-Care Activities Scale scores between the two groups ( P>0.05). The difference in changes in diabetic foot self-screening scores between intervention group and control group was statistically significant ( P<0.05) . Conclusions:Specialist nurse-led precision health care management utilizing digital platforms can improve HbA1c and enhance self-management behaviors for diabetic foot in patients with type 2 diabetes, which is expected to be promoted and applied in the outpatient management of diabetes patients.

To explore the interaction between ASFV capsid protein M1249L and host from the host cellular perspective,M1249L was selected for constructing the bait plasmid(pGBKT7-M1249L)to screen the bone marrow-derived macrophages(BMDMs)cDNA library.After again co-transform and sequence alignment,20 candidate interacting host proteins were screened,such as IL-1β,CTSB and DNAJA3.And then,co-immunoprecipitation assay was performed to verify the interaction be-tween M1249L and host proteins.GO ontology(GO)and KEGG pathway enrichment analyses re-vealed that biological regulation,cellular communication and response to stimulus and others were enriched in biological processes.And these host proteins could share some pathways,including toll-like receptor signaling pathway and Nod-like receptor signaling pathway.Therefore,the results provides the theoretical basis for further research on the mechanism of ASFV M1249L in viral in-fection and immune regulation.

There are multiple signaling communication modalities for the biological activities of single cells or groups of cells. The elucidated modalities include neuronal electrical signal communication, long-distance communication mediated by hormones, and short-range signal communication secreted by cells into the extracellular environment, etc. Recently, many studies have shown that mechanical forces are also extensively involved in the information exchange between cells or between cells and the external environment, especially in the signal communication among epithelial cells or between epithelial cells and the extracellular matrix. The cell communication triggered by mechanical forces is instantaneous and rapid, and it affects various activities of both individual epithelial cells and epithelial cell clusters. The mediators of cell communication induced by mechanical forces include actin, myosin, cytoskeleton, and adherens junctions, etc. These mediators trigger processes such as ion flow, activation of signaling pathways, and regulation of transcription factors through mechanical signals, thereby interfering with cell behaviors. This article elaborates on the impacts of mechanical forces on epithelial cells from multiple aspects, including biological signals, three-dimensional folding, collective migration, cell metabolism, carcinogenesis, and epithelial-mesenchymal transition.

Alzheimer′s disease is a serious neurodegenerative disorder. Approximately 80% to 90% of patients are accompanied by behavioral and psychological symptoms of dementia (BPSD), which manifest as a series of behavioral, psychological and mental abnormalities. These abnormalities can accelerate the cognitive deterioration and premature death of patients, and thus are regarded as important clinical symptoms. However, the pathogenesis of BPSD is still unknown, and treatment methods are limited. The pathogenesis of BPSD from the perspective of neuroimaging and pathophysiology, and possible treatment measures were analyzed in this article, in order to provide references for the early diagnosis and treatment of BPSD.
