AIM: To investigate the influence of relevant inflammatory markers in peripheral blood on the progression of neovascular glaucoma(NVG)secondary to diabetic retinopathy(DR)patients.METHODS: Retrospective case-control study. Patients were categorized into two groups based on the presence or absence of NVG: those with proliferative diabetic retinopathy(PDR)alone(PDR group, n=148)and those with NVG secondary to PDR(NVG secondary to PDR group, n=142). Peripheral blood inflammatory markers were evaluated, including white blood cell-related indices, neutrophil-to-lymphocyte ratio(NLR), platelet-to-lymphocyte ratio(PLR), monocyte-to-lymphocyte ratio(MLR), and systemic immune-inflammation index(SII). The distinctions in peripheral blood inflammatory markers between the two groups of patients and their relationships with NVG secondary to PDR were analyzed.RESULTS:No statistically significant differences were observed in basic characteristics between the two groups, confirming their comparability. However, significant differences were found in eosinophil percentage and MLR between the PDR group and the NVG secondary to PDR group(all P<0.05), with both values being significantly higher in the NVG secondary to PDR group. Multivariate Logistic regression analysis revealed that the eosinophil percentage and the MLR were factors influencing the development of patients with NVG secondary to PDR.CONCLUSION: Eosinophil percentage and MLR may be associated with the progression of PDR to NVG, and could serve as potential predictive markers for NVG development in PDR patients.

The incidence of knee osteoarthritis(KOA)is in-creasing year by year,seriously affecting patients'health.Mes-enchymal stem cells are multipotent cells with multiple differen-tiation functions.The extracellular vesicles released by these cells can carry various"cargo"to corresponding cells and tis-sues,exerting biological functions.They have shown great clini-cal potential in the treatment of KOA.This study reviews the therapeutic effects and mechanisms of extracellular vesicles se-creted by mesenchymal stem cells from different tissues such as bone marrow,adipose tissue,and synovium in KOA.It is found that miRNA is an important biological component in exerting therapeutic effects.The study also discusses the research pro-gress of engineered extracellular vesicles in KOA,pointing out the current challenges in clinical application,such as standard-ized acquisition of extracellular vesicles and difficulties in targe-ted action,aiming to provide a certain reference for the basic re-search and clinical application of extracellular vesicle therapy for KOA.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective:To summarize the content and effects of exercise interventions for stroke survivors, providing references for medical and nursing personnel in formulating exercise intervention plans for these patients.Methods:Literature on exercise interventions for stroke survivors was searched in databases such as China National Knowledge Infrastructure, Wanfang, VIP, China Biology Medicine disc, Cochrane Library, PubMed, Embase, and Web of Science up to May 1, 2023. Data extraction and summarization were conducted on the included literature.Results:Twenty-two articles were included in the review. The exercise types for stroke survivors primarily involved aerobic and resistance training; the intensity was mainly moderate to high; the frequency was mostly 3-5 times per week, with each session lasting 30-60 minutes; and the duration of interventions ranged from as short as two weeks to as long as one year. Exercise interventions improved stroke survivors' functional mobility, quality of life, cardiopulmonary function, mental state, cognitive function, fatigue, sleep, and compliance to varying degrees.Conclusions:Exercise interventions have achieved positive outcomes in stroke survivors. In the future, medical and nursing personnel can incorporate patient preferences into exercise intervention plans while ensuring patient safety to promote rehabilitation.

This study was aimed at understanding the detection rate,drug resistance characteristics,virulence characteris-tics,multi-locus sequence typing,and other molecular epidemic and pathogenic characteristics of Campylobacter jejuni and Campylobacter coli in children in Guangdong Province from 2020 to 2022.Anal swabs or stool samples of suspected infection cases in children from 2020 to 2022 were collected from two hospitals in Guangzhou,Guangdong Province.Campylobacter was isolated and cultured through the filtration method,and identified with a microbial mass spectrometry system;antibiotic resist-ance was analyzed with the agar dilution method;bacterial genome nucleic acids were extracted,and whole-genome sequencing was conducted;and drug resistance genes,virulence genes,multi-locus sequence typing,and phylogenetic analysis based on whole-genome single nucleotide polymorphisms were analyzed from whole-genome sequencing results.First,53 strains of Campy-lobacter were detected through continuous routine monitoring in this study,with a positive detection rate of 2.94％.Among them,Campylobacter jejuni accounted for 81.13％(43/53)and Campylobacter coli accounted for 18.87％(10/53).In addition,16 strains of Campylobacter were screened through multi-pathogen surveillance,including 11 strains of Campylobacter jejuni and 5 strains of Campylobacter coli.Drug resistance ex-periments and whole genome sequencing were conducted on 46 Campylobacter isolates,including 33 isolates of Campylobacter jejuni and 13 isolates of Campylobacter coli.The resistance rate of Campylobacter to erythromycin,a widely used clinical treatment,was21.73％(10/46);that to tetracycline was 80.43％(37/46);those to the quinolone antibiotics nalidixic acid and ciprofloxacin were 76.08％(35/46)and 71.73％(33/46)respectively;and that to chloramphenicol was lowest,at 2.17％(1/46).The drug resistance rate was generally higher for Campylobacter coli than Campylobacter jejuni,and the differences in the indicators of erythromycin,gentamicin,streptomycin,telithromycin,and clindamycin were statistically significant.A total of 30 isolates of multidrug-resistant Campylobacter were detected,including nine multidrug-resistant phenotypes.Whole-ge-nome sequence analysis indicated that 46 Campylobacter isolates carried antibiotic resistance genes for antibiotics such as quino-lones,tetracyclines,β-lactams,and aminoglycosides,and carried 128 virulence factor genes in five categories.All 46 isolates of Campylobacter were identified as 35 ST type through MLST typing,and phylogenetic analysis indicated no obvious dominant ST type.Campylobacter coli had more SNPs than Campylobacter jejuni.In conclusion,the positive detection rate of Campy-lobacter in Guangzhou City,Guangdong Province stabilized from 2020 to 2022,and the detection rate of Campylobacter jejuni was higher than that of Campylobacter coli.Campylobacter isolates were resistant to tetracyclines and quinolone,and showed a wide spectrum of multi-drug resistance,which was relatively severe among Campylobacter coli.Resistance genes and drug-resistant phenotypes were correlated and had predictive significance.The virulence genes of Campylobacter jejuni were more a-bundant than those of Campylobacter coli,possibly because of the higher detection rate and pathogenicity of Campylobacter jejuni.The phylogenetic tree showed clear branches with high genetic diversity and no clearly dominant clonal group.

To investigate the prevalence and epidemiological characteristics of diabetic retinopathy (DR) in Yunnan Province, explore its risk factors, and provide a basis for the prevention and treatment of chronic complications of diabetes mellitus (DM). This is a large cross-sectional study, in all, 1 524 DM patients in 16 communities and villages of Yunnan Province who were registered in health service centers were included in this study from August to November 2019. All patients completed a uniform questionnaire, anthropometric measurements, biochemical measurements, and auxiliary examinations. Logistic regression analysis was used to screen the risk factors of DR. The prevalence rates of DR, mild non-proliferative DR (mild-NPDR), and referable DR (RDR) were 16.0% (244/1 524), 4.5% (69/1 524), and 11.5% (175/1 524), respectively. Glycated hemoglobin A 1c (HbA 1c)≥7.0% was the risk factor of mild-NPDR ( OR=1.872, 95% CI 1.055-3.323) and RDR ( OR=4.821, 95% CI 2.917-7.969). Blood pressure≥130/80 mmHg (1 mmHg=0.133 kPa) was the risk factor of mild-NPDR ( OR=1.933, 95% CI 1.112-3.358) and RDR ( OR=1.505, 95% CI 1.063-2.130). In Yunnan Province, 16.0% DM patients had accompanying DR, wherein about 71.7% of them required an ophthalmology referral, and the high incidence of RDR in DM patients was associated with poor control of blood glucose and blood pressure.

Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.

BACKGROUND:Nano-zirconium dioxide has good application potential in the field of bone tissue repair.Studying the effect of nano-zirconium dioxide on osteogenic differentiation will help to promote the clinical application of nano-zirconium dioxide in the treatment of bone defects. OBJECTIVE:To explore the effect of nano-zirconium dioxide on the osteogenic differentiation of ectomesenchymal stem cells in the nasal mucosa. METHODS:Ectomesenchymal stem cells derived from rat nasal mucosa were isolated and cultured,and the biotoxicity of nano-zirconium dioxide to the cells was detected by CCK-8 assay.The biosafety concentration was selected according to the cytotoxicity,and the cells were randomly divided into a control group,a nano-zirconium dioxide group,and a nano-hydroxyapatite group.Osteogenic differentiation of cells was directionally induced in each group.On day 7 of induced differentiation,alkaline phosphatase staining was performed.qRT-PCR and western blot assay were used to detect the expression of early osteogenic markers(Runx2 and Osx).On day 21 of induced differentiation,alizarin red staining was conducted.qRT-PCR and western blot assay were utilized to determine the expression levels of late osteogenic markers(OPN and OCN). RESULTS AND CONCLUSION:(1)The median lethal concentration of nano-zirconium dioxide on ectomesenchymal stem cells in nasal mucosa was 0.6 mg/mL.In the experiment,the mass concentration of 200 μg/mL was selected for intervention.Zirconium dioxide had no significant effect on the proliferation of the cells.(2)Compared with the control group,the alkaline phosphatase staining of the cells in the nano-zirconium dioxide group was more obvious and the level of cell mineralization was higher,but there was no significant difference compared with the nano-hydroxyapatite.(3)Compared with the control group,the expression of bone-related genes and proteins increased significantly,but there was no significant difference compared with nano-hydroxyapatite.(4)The results show that nano-zirconium dioxide has good biological safety and can promote the osteogenic differentiation of ectomesenchymal stem cells in the nasal mucosa.This promoting effect is equivalent to that of nano-hydroxyapatite.
