Glaucoma, the leading cause of irreversible blindness worldwide, remains a central focus of ophthalmic research, particularly with regard to surgical management. Conventional procedures, such as trabeculectomy with mitomycin and glaucoma drainage device implantation, continue to be considered the gold standard because of their strong intraocular pressure lowering efficacy. However, these operations are associated with relatively high rates of postoperative complications, and perioperative fluctuations in intraocular parameters can introduce refractive prediction errors that ultimately compromise visual quality. In recent years, minimally invasive glaucoma surgery(MIGS)has gained increasing attention for its advantages in reducing complications, shortening operative time, minimizing incision size, and accelerating visual recovery, while better preserving postoperative refractive stability. This review systematically summarizes the differences in refractive outcomes between conventional surgery and MIGS, examines the underlying mechanisms, and discusses practical clinical strategies to manage refractive shifts. The aim is to provide a theoretical foundation for precise refractive management in glaucoma surgery, thereby enhancing patients' visual quality and overall quality of life.

Objective: To understand the awareness of chikungunya fever knowledge and its related factors among medical college students in Baise City, so as to provide a scientific basis to offer relevant courses and special education. Methods: From July to August 2025, 7 286 enrolled medical students were selected by a sampling method from a medical college in Baise City to participate in the questionnaire survey. The questionnaire covered epidemiological characteristics, clinical symptoms, and prevention/control knowledge of chikungunya fever. Statistical analyses including the Chi quare test and multivariate Logistic regression models were performed. Results: The overall awareness rate of chikungunya fever knowledge among the medical students was 18.89%. Among the knowledge items, the awareness rate of "the high incidence season" was the highest (84.05%), while that of "the infectious period" was the lowest (17.80%). Multivariate Logistic regression analysis showed that medical students with female (a OR= 1.37 , 95%CI =1.20- 1.57 ), the age for over 25 years old (a OR=1.76, 95%CI =1.05-2.93), whose father had a middle school educational level (a OR=1.18, 95%CI =1.05-1.31), and majored in preventive medicine (a OR=1.54, 95%CI =1.10-1.67) had relatively higher awareness rates of chikungunya fever knowledge (all P <0.05). In contrast, students of Zhuang ethnicity (a OR= 0.87 , 95%CI =0.76-0.98) and majoring in nursing (a OR=0.74, 95%CI =0.61-0.91) or pharmacy (a OR=0.70, 95%CI =0.52-0.95) had relatively lower awareness rates (all P <0.05). Conclusions The awareness rate of chikungunya fever related knowledge among medical college students in Baise City is relatively low. Schools should take targeted publicity measures to improve medical students awareness.

BACKGROUND:Studies have shown that gut microbiota may affect the progression of rheumatoid arthritis.However,the causal relationship between the two is unknown.Mendelian randomization analysis of the two using published Genome Wide Association Study(GWAS)data can explore the causal relationship between gut microbiota and rheumatoid arthritis,helping to develop targeted microbial therapies and provide methods and strategies for the prevention and treatment of rheumatoid arthritis.OBJECTIVE:To explore the potential causal relationship between gut microbiota and rheumatoid arthritis using two-sample two-way Mendelian randomization method.METHODS:Gut microbiota GWAS data from the MiBio-Gen consortium and rheumatoid arthritis GWAS data from the IEU Open GWAS database(a large gene-phenotype association database developed at the MRC Integrative Epidemiology Unit(IEU)at the University of Bristol,UK)were used.Inverse variance weighting was used as the main analysis method,and MR-Egger regression method,weighted median method,weighted model and simple model method were used as supplements to study the causal relationship between gut microbiota and rheumatoid arthritis.Heterogeneity was assessed using Cochran's Q test,horizontal pleiotropy was assessed using MR-PRESSO and MR-Egger intercept tests,robustness of results was tested using leave-one method,and reverse Mendelian randomization analysis was used to assess the presence or absence of reverse causality.RESULTS AND CONCLUSION:(1)There was a causal relationship between five kinds of enteric bacteria and rheumatoid arthritis.Ruminococcus gauvreauii group(β=0.262,odds ratio[OR]=1.300,P=0.013)and Butyricimonas(β=0.001,OR=1.001,P=0.014)increased the risk of rheumatoid arthritis,while Anaerostipes(β=-0.225,OR=0.798,P=0.025),Lachnospiraceae-UCG010(β=-0.177,OR=0.838,P=0.026)and Oxalobacter(β=-0.171,OR=0.843,P=0.001)reduced the risk of rheumatoid arthritis.Sensitivity analyses showed no significant heterogeneity or horizontal pleiotropy(all P＞0.05),and leave-one-out testing confirmed the robustness of the results,while the addition of the remaining four methods other than the inverse variance weighting method further validated the reliability and stability of the results.(2)Reverse Mendelian randomization analysis did not find a causal association between rheumatoid arthritis and the five kinds of enteric bacteria identified by Mendelian randomization analysis.These findings indicate that Ruminococcus gauvreauii group and Butyricimonas may be the risk factors of rheumatoid arthritis,while Anaerostipes,Lachnospiraceae-UCG010 and Oxalobacter may be the protective factors of rheumatoid arthritis.Gut microbiota may play an important role in the pathogenesis of rheumatoid arthritis,and provide new biomarkers for the prevention and treatment of rheumatoid arthritis.In addition,for the field of biomedical research in China,we can learn from international experience and gradually establish and improve a multi-center large-scale genetic database,so as to deeply explore the relationship between gut microbiota and disease risk,and promote the development of precision medicine and personalized treatment in China.

Acute B-lymphoblastic leukemia (B-ALL) is the most common type of acute lymphoblastic leukemia. Chemotherapy is the main treatment for most patients, but there are serious side effects. CD19 is generally highly expressed in B-lineage malignancies and plays a key role in B cell signal transduction, activation and development. Therefore, it has become one of the effective targets for treatment of B-cell malignancies. At present, a variety of therapies targeting CD19 have been developed, including antibody drug conjugates, monoclonal antibodies, bispecific antibodies and chimeric antigen receptors cell therapies. This paper reviews the clinical trial progress of CD19-targeted therapy for B-ALL.

Objective To establish a fluorescent assay for rapid detection of Plasmodium falciparum based on recombinaseaided amplification (RAA) and CRISPR-Cas12a system,and to preliminarily evaluate the diagnostic efficiency of this system.. Methods The 18S ribosomal RNA (rRNA) gene of P. falciparum was selected as the target sequence, and three pairs of RAA primers and CRISPR-derived RNA (crRNA) were designed and synthesized. The optimal combination of RAA primers and crRNA was screened and the reaction conditions of the system were optimized to create a fluorescent RAA/CRISPR-Cas12a system. The plasmid containing 18S rRNA gene of the P. falciparum strain 3D7 was generated, and diluted into concentrations of 1 000, 100, 10, 1 copy/μL for the fluorescent RAA/CRISPR-Cas12a assay, and its sensitivity was evaluated. The genomic DNA from P. vivax, P. malariae, P. ovum, hepatitis B virus, human immunodeficiency virus and Treponema pallidum was employed as templates for the fluorescent RAA/CRISPR-Cas12a assay, and its specificity was evaluated. Fifty malaria clinical samples were subjected to the fluorescent RAA/CRISPR-Cas12a assay and nested PCR assay, and the consistency between two assays was compared. In addition, P. falciparum strain 3D7 was cultured in vitro. Then, the culture was diluted into blood samples with parasite densities of 1 000, 500, 200, 50, 10 parasites/μL with healthy volunteers’ O-positive red blood cells for the RAA/CRISPR-Cas12a assay, and the detection efficiency was tested. Results The Pf-F3/Pf-R3/crRNA2 combination, 2.5 μL as the addition amount of B buffer, 40 min as the RAA reaction time, 37 °C as the reaction temperature of the CRISPR-Cas12a system were employed to establish the fluorescent RAA/CRISPR-Cas12a system. Such a system was effective to detect the plasmid containing 18S rRNA gene of the P. falciparum strain 3D7 at a concentration of 1 copy/μL, and presented fluorescent signals for detection of P. falciparum, but failed to detect P. ovum, P. malariae, P. vivax, T. pallidum, hepatitis B virus or human immunodeficiency virus. The fluorescent RAA/CRISPR-Cas12a system and nested PCR assay showed completely consistent results for detection of 50 malaria clinical samples (kappa = 1.0, P < 0.001). Following 6-day in vitro culture of the P. falciparum strain 3D7, 10 mL cultures were generated and the fluorescent RAA/CRISPR-Cas12a system showed the minimal detection limit of 50 parasites/μL. Conclusion The fluorescent RAA/CRISPR-Cas12a system is rapid, sensitive and specific for detection of P. falciparum, which shows promising value for rapid detection and risk monitoring of P. falciparum.

OBJECTIVE: To assess the association of SLC6A4 gene c.*670T>G polymorphism with the risk for asthma and peripheral blood cytological characteristics among ethnic Zhuang Chinese from Guangxi, China. METHODS: From May 2017 to March 2020, 258 patients diagnosed with asthma and 244 healthy controls were recruited from the Affiliated Hospital of Youjiang Minzhu Medical College and the People's Hospital of Hechi. Genotypes of the c.*670T>G polymorphism were determined by Sanger sequencing. Flow cytometry was used in combination with an electrical impedance method for the counting and classification of peripheral blood cells. RESULTS: Compared with the T allele, the G allele of the c.*670T>G polymorphism was associated with the risk for asthma in the population (OR = 1.54, 95%CI = 1.15-2.06; P = 0.004). Compared with the GT and TT genotypes, homozygous GG genotype also comprised a risk factor (OR = 1.66, 95%CI = 1.16-2.38; P = 0.005). Stratification of the risk factors showed that the homozygous GG genotype has increased the risk of asthma in males and urban residents (P < 0.01). The erythrocyte, hemoglobin and platelet counts of the asthma group were significantly higher than the control group (P < 0.001). The GG, GT and TT genotypes have respectively accounted for 82.35%, 17.65% and 0% of the samples with platelets exceeding the normal value. The overall platelet level of GG genotype was higher than GT+TT genotype (P < 0.05). The significant association was verified by the false positive report probability, and at a prior probability level of 0.1, G vs. T false positive probability was 0.071, and GG vs. GT+TT false positive probability was 0.153. CONCLUSION The GG genotype of the c.*670T>G polymorphism is associated with the risk for asthma among ethnic Zhuang Chinese from northwest Guangxi. Above finding has also enriched the genotypic data and peripheral blood phenotype for this polymorphism.
