ObjectiveTo construct a prediction model for high responsiveness to short-term aerobic training in patients with Parkinson's disease (PD) based on dual-task gait assessment, and to provide evidence for identifying individuals who are most likely to benefit from such interventions. MethodsA total of 42 patients with PD who visited the outpatient clinic of Tianjin Huanhu Hospital between August 29, 2023 and December 19, 2024 were enrolled. All participants completed a 4-week home-based aerobic cycling training program and underwent dual-task gait assessments pre- and post-training. Patients were classified into high-response group (n = 12) and low-response group (n = 30) according to whether the improvement in gait speed reached the minimal clinically important difference of 0.1 m/s. The clinical validity of this grouping was verified by comparing differences in cardiopulmonary exercise testing parameters and dual-task gait indicators between the two groups pre- and post-training. Based on baseline characteristics, Firth's penalized maximum likelihood logistic regression was applied to construct a predictive model for high responsiveness, and the discriminative performance of the model was assessed preliminarily. ResultsThe high-response group showed significantly greater improvement in gait speed, step length, cadence and the anaerobic threshold to maximal oxygen uptake ratio after training compared with the low-response group (P < 0.05), confirming the clinical validity of the grouping. The baseline anaerobic threshold to maximal oxygen uptake ratio (OR = 3.348), body mass index (OR = 2.229) and age (OR = 0.428) demonstrated certain discriminative ability in the present sample. The area under the receiver operating characteristic curve was 0.831, with an overall prediction accuracy of 81.0%, specificity of 83.3% and sensitivity of 75.0%. Robustness of the model was confirmed via internal validation using the Bootstrap method, which suggested that the results were informative, but further validation was still required. ConclusionThe anaerobic threshold/maximal oxygen uptake ratio, body mass index and age may predict the response to short-term aerobic training in patients with PD.

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.

Objectives:To investigate the screening status of warning signs for mental and behavioral development (WS) and influencing factors of infants and young children (IYC) in poverty eliminated regions of Henan Province.Methods:This study was a cross-sectional study. A total of 15 680 IYC aged 6-23 months from 51 poverty eliminated counties in Henan province from June to September of 2023 were selected through a multi-stage random sampling method. IYC′s early warning signs were screened using the WS checklist (WSC). Children′s socio-demographic characteristics, maternal information, birth status, and illness conditions such as fever and diarrhea within 2 weeks were measured through a uniformly designed questionnaire. All participants also received the measurement of height, weight, and hemoglobin concentration level. Logistic regression model was used to explore the influencing factors of positive WSC and conducted sensitivity analyses.Results:Among the sample of 15 680 IYC, there were 8 462 boys (53.97%) and 7 218 girls (49.03%), with their age of (15±5) months. A total of 291 (1.86%) IYC were positive in WSC. Parenting risk ( OR=5.07, 95% CI 3.93-6.52, P<0.001) and preterm birth ( OR=1.63, 95% CI 1.06-2.52, P=0.027) were both positively associated with the odds of WSC′s positivity. Being girls ( OR=0.66, 95% CI 0.52-0.85, P=0.001), age (12-17 months, OR=0.47, 95% CI 0.35-0.62, P<0.001; 18-23 months, OR=0.40, 95% CI 0.30-0.54, P<0.001), and maternal educational level (junior high school, OR=0.46, 95% CI 0.32-0.66, P<0.001; senior high school or vocational high school, OR=0.35, 95% CI 0.23-0.56, P<0.001; college and above, OR=0.36, 95% CI 0.23-0.57, P<0.001) were all negatively associated with the risk of WSC′s positivity. Sensitivity analyses demonstrated that, after excluding anemic children, the association between preterm birth and WSC′s positivity was not significant ( OR=1.54, 95% CI 0.95-2.49, P=0.081). Despite this situation, being girls, age and maternal educational level were still negatively associated with the odds of WSC′s positivity (all P<0.05); preterm birth, parenting risk were remained positive associated with the risk of WSC′s positivity (all P<0.05) either by excluding children with protein-energy malnutrition or 2-week morbidity, or using prevalence ratio instead of OR. Conclusions:Among the IYC in poverty eliminated regions of Henan Province, the risk of positivity of WSC was higher for those IYC with parenting risk, preterm birth, boys, younger age, and lower maternal education level. These influencing factors, such as gender, age, preterm birth, parenting risk and maternal educational level, were in certain stability across different IYC characteristics and estimation models.

Objective: To investigate the effects of glycosylated hemoglobin A1c (HbA1c) from the patients with double heterozygotes Hb Q-H and Hb J-Bangkok combined with β-thalassemia on the results of different HbA1c detection systems. Methods: Blood samples from 20 healthy adults and 20 patients with type 2 diabetes mellitus (T2DM) were collected to assess the results of five glycosylated hemoglobin detection systems. Blood samples from one Hb Q-H patient and one Hb J-Bangkok patient with β-thalassemia were also collected, and they were performed hemoglobin capillary electrophoresis with Capillarys2 and globin gene analysis by gap-PCR, PCR-RDB and DNA sequencing. The levels of HbA1c in all samples were detected by BioRad VARIANT Ⅱ (VⅡ), BioRad VARIANT ⅡTurbo2.0 (V Ⅱ-T2.0), Capillarys 2 Flex Piercing (C2FP), Primus Ultra2 (Ultra2) and Roche PPI 800 (PPI 800) glycosy lated hemoglobin detection instruments, respectively. For the samples with double heterozygotes, the levels of HbA1c were detected for 3 times each sample, and the results were preserved and analyzed. Results: The genotype of the Hb Q-H sample was --α QT /--SEA;β N /β N , and HbA1 CD74 G＞C mutation occurred in globin α1 chain, forming Hb Q-Thailand hemoglobin variant without normal α-globin peptide chain. The genotype of Hb J-Bangkok combined with β-thalassemia was αα/αα;βCD56/βCD41-42, and the point mutation of GGC＞GAC occurred at codon 56 of globin β-chain, forming Hb J-Bangkok hemoglobin variant without normal β-globin peptide chain. For the Hb Q-H sample, HbA1c results were reported by 3 of 5 HbA1c detection systems. The chromatograms of VⅡ and VⅡ-T2.0 detection systems were obviously different from normal chromatograms, and HbA1c results were not reported. However, the chromatograms of the C2FP system were similar to normal chromatograms, and the result of HbA1c was 3.7%. The Ultra2 system and PPI system reported the HbA1c results, 5.3% and 5.7%, respectively, without abnormal alarm. For the Hb J-Bangkok with β-thalassemia sample, HbA1c results were also reported by 3 of 5 HbA1c detection systems. The chromatograms of VⅡ and Sebia detection systems were obviously different from normal chromatograms, and HbA1c results were not reported. However, the chromatograms of VⅡ-T2.0 system were different from normal chromatograms, and a P4 peak (84.9%) was found. The HbA1c result was reported as 4.7%. The Ultra2 system and PPI system reported the HbA1c results, 4.7% and 3.8%, respectively, without abnormal alarm. Conclusion The samples from the Hb Q-H patient and the Hb J-Bangkok patient with β-thalassemia do not contain normal HbA, and there should be no HbA1c results. The chromatograms of VⅡ and VⅡ-T systems are obviously abnormal, indicating that the results can not be reported. The C2FP system is interfered obviously by Hb Q-H, but reports the HbA1c results, while it does not report the HbA1c results of Hb J-Bangkok combined with β-thalassemia. Both of Hb Q-H and Hb J-Bangkok have obvious interference to PPI and Ultra2 detection systems.

Quorum sensing (QS) plays a major role in the outbreak mechanism of foodborne diseases caused by food poisoning and food spoilage. QS affects the formation of cell membrane and pathogenicity ofpathogenic bacteria. Through the in-depth understanding of QS molecules of food-borne pathogens, we describe here the types of signal molecules produced by Gram-negative and Gram-positive bacteria, and the differences in QS molecules. Meanwhile, we introduce the detection of QS molecules by different technologies. According to the influence of QS on food, we propose also future research needs for the control of foodborne pathogenic bacteria.
