Objective:To screen for microRNAs(miRNAs)highly expressed in the serum exosomes(Exo)of esophageal squamous cell carcinoma(ESCC)patients and analyze their relationship with the clinicopathological characteristics of the patients,and to explore the potential of Exo-derived miRNAs as clinical auxiliary diagnostic markers for ESCC.Methods:Serum and relevant clinical data of 50 healthy subjects and 45 newly diagnosed ESCC patients admitted to the Fourth Hospital of Hebei Medical University between December 2021 and June 2023 were collected,serving as the control group and the ESCC group respectively.The Gene Expression Omnibus(GEO)database and qPCR were used to screen and identify the candidate miRNA for increased expression in the serum of ESCC patients-miR-1246.The diagnostic efficacy of serum miR-1246 for ESCC was analyzed by the receiver operating characteristic curve.The relationship between miR-1246 and the clinical feature progression of ESCC patients was analyzed by Logistic regression,and the relationship between miR-1246 and the clinicopathological characteristics of ESCC patients was analyzed by the χ2 test.Exosomes in the serum of the subjects were isolated,purified and characterized for verification.The expression of miR-1246 in Exo was detected by qPCR.ESCC KYSE150 and KYSE30 cells were routinely cultured.mimics-NC and miR-1246 mimics were transfected respectively into KYSE150 cells using Lipofectamine 2000.Inhibitor-NC and miR-1246 inhibitor were transfected into KYSE30 cells,which were respectively denoted as the minics-NC,miR-1246 mimics,inhibitor-NC and miR-1246-inhibitor groups.KYSE150 and KYSE30 cells were treated with Exo derived from KYSE150 cells in the mimics-NC and miR-1246 mimics groups.The proliferation,migration and invasion abilities of cells in each group were detected by the CCK-8 assay,scratch wound healing assay and Transwell chamber assay respectively.The expressions of Exo markers,epithelial-mesenchymal transition-related proteins,TET family methylcytosine dioxygenase 2(TET2)and cell adhesion molecule 1(CADM1)proteins in each group of cells were detected by WB assay.The targeting binding relationship between miR-1246 and TET2 and CADM1 was verified by the dual-luciferase reporter gene assay.Results:Bioinformatics screening showed that the miRNA with the most significant differential expression in the serum of ESCC patients was miR-1246.The serum Exo extracted from the patients conformed to the typical Exo characteristics.The expression level of serum Exo-miR-1246 in ESCC patients at stages Ⅰ-Ⅱ was significantly higher than that in healthy subjects(P<0.01);the level of serum Exo-miR-1246 in ESCC patients at stages Ⅲ-Ⅳ was significantly higher than that in patients at stages Ⅰ-Ⅱ(P<0.01).ROC curve analysis showed that Exo-miR-1246 in serum had a high value for auxiliary differential diagnosis of ESCC(P<0.05),and the auxiliary diagnostic efficacy of Exo-miR-1246 for the clinical progression of ESCC patients was higher than that of CEA and SCC-Ag(P<0.05).The combined detection of the three could further improve the efficacy of auxiliary diagnosis of patient staging(P<0.01).Exo-miR-1246 might be an independent risk factor for the clinical progression of ESCC patients(P<0.05).The expression level of serum Exo-miR-1246 was associated with the T-stage,N-stage and clinical stage of ESCC(P<0.01).Overexpression of miR-1246 could promote the proliferation,migration,invasion,epithelial-mesenchymal transition and inhibit apoptosis of ESCC cells,while inhibition of miR-1246 had the opposite effect.Database data analysis found that TET2 and CADM1 were the target genes of miR-1246.The dual-luciferase reporter gene assay confirmed that miR-1246 could directly bind to TET2 and CADM1 mRNA and inhibit their expressions(P<0.01).Treatment of KYSE150 and KYSE30 cells with Exo derived from cells overexpressing miR-1246 had the same effect as overexpressing miR-1246 in these cells.Conclusion:Exo-derived miR-1246 has the potential to be a clinical auxiliary diagnostic marker for ESCC.It may affect the occurrence and development of ESCC by regulating the expression levels of TET2 and CADM1.

Objective: To investigate the influencing factors for kinesiophobia among elderly patients with chronic obstructive pulmonary disease (COPD), so as to provide the reference for alleviating kinesiophobia among COPD patients. Methods: From December 2023 to July 2024, COPD patients aged 60 years and above who sought medical treatment at a tertiary grade-a hospital in Guiyang City were selected. Demographic information was collected through questionnaire surveys.

Factors affecting kinesiophobia among elderly patients with COPD were analyzed using a multiple linear regression model. Results: A total of 300 COPD patients were surveyed, including 238 males (79.33%) and 62 females (20.67%). The majority of patients had a disease duration of less than 5 years, with 130 cases (43.33%). The average kinesiophobia score was (48.01±7.74) points. The average exercise self-efficacy score was (3.39±1.01) points. The average social support score was (34.42±6.76) points. There were 280 patients (93.33%) with type D personality. The average scores of the confrontation, avoidance, and resignation dimensions of coping styles were (17.42±5.00), (13.76±1.91), and (11.81±2.95) points, respectively. Multiple linear regression analysis showed that age (70-<80 years, β'=0.124; ≥80 years, β'=0.205), educational level (primary school and below, β'=0.228; junior high school, β'=0.182), household monthly income per capita (<3 000 yuan, β'=0.234; 3 000~<5 000 yuan, β'=0.165), social support (β'=0.294), type D personality (β'= 0.170), and coping styles (confrontation dimension, β'=-0.140; avoidance dimension, β'=0.154; resignation dimension, β'=0.175) statistically associated with kinesiophobia among elderly patients with COPD. Conclusion Kinesiophobia among elderly patients with COPD is associated with age, educational level, household monthly income per capita, social support, type D personality and coping styles.

OBJECTIVE To investigate the expression of long non-coding RNA(lncRNA)HOXC13-AS in head and neck squamous cell carcinoma tissues and its effects on tumor cell proliferation and migration in head and neck tumor cell lines.METHODS Clinical samples from 26 patients with laryngeal squamous cell carcinoma and 4 patients with hypopharyngeal squamous cell carcinoma who were treated surgically in the Second Hospital of Jilin University from March 2024 to December 2024 were collected as research subjects.Head and neck squamous cell carcinoma tissue specimens and corresponding adjacent tissue specimens were selected.The expression of HOXC13-AS in 30 cases of head and neck squamous cell carcinoma tissues and corresponding adjacent tissues was detected by real-time fluorescence quantitative polymerase chain reaction(qRT-PCR).Clinical data were collected to analyze the correlation between HOXC13-AS expression and various clinical pathological factors.siRNA technology was used to interfere with the expression of HOXC13-AS in laryngeal cancer cell line TU212 and hypopharyngeal squamous cell line FaDu.Cell Counting Kit-8(CCK-8)assay was used to detect cell proliferation ability,and cell scratch assay was used to detect cell migration ability.RESULTS The expression level of lncRNA HOXC13-AS in head and neck squamous cell carcinoma tissues(12.60±11.26)was significantly higher than that in corresponding adjacent tissues(1.40±0.61),with a statistically significant difference(t=5.485,P<0.001).The expression of HOXC13-AS in head and neck squamous cell carcinoma tissues was closely related to T stage(P=0.004),lymph node metastasis(P=0.006),and clinical stage(P=0.007)of patients.CCK-8 results showed that the absorbance values of TU212 cell line groups at 24,48,and 72 h were si-NC group(0.373±0.010,0.738±0.026,1.003±0.124),si-HOXC13-AS-1 group(0.365±0.015,0.686±0.019,0.935±0.028),and si-HOXC13-AS-2 group(0.364±0.024,0.700±0.026,0.943±0.053),with statistically significant differences(F24 h=0.484,F48 h=7.893,F72 h=1.345,P<0.01);the absorbance values of FaDu cell line groups at 24,48,and 72 h were si-NC group(0.727±0.054,0.834±0.072,1.224±0.127),si-HOXC13-AS-1 group(0.532±0.005,0.650±0.079,1.021±0.044),and si-HOXC13-AS-2 group(0.647±0.088,0.687±0.025,1.074±0.055),with statistically significant differences(F24 h=16.143,F48 h=14.259,F72 h=9.409,P<0.001).Cell scratch assay showed that the migration rates of TU212 cell line groups at 12 and 24 h were si-NC group(38.971%±3.824%,69.185%±0.469%),si-HOXC13-AS-1 group(18.182%±2.580%,33.378%±2.302%),and si-HOXC13-AS-2 group(25.017%±0.288%,48.413%±0.805%),with statistically significant differences(F12 h=47.295,F24 h=471.745,P<0.0001);The migration rates of FaDu cell lines in each group at 12 and 24 hours were as follows:si-NC group(39.067%±3.196%,58.222%±0.448%),si-HOXC13-AS-1 group(13.689%±0.132%,39.358%±3.985%),and si-HOXC13-AS-2 group(23.335%±0.680%,35.526%±0.758%),with statistically significant differences(F12 h=138.1,F24 h=101.749,P<0.0001).CONCLUSION HOXC13-AS is significantly upregulated in head and neck squamous cell carcinoma tissues and cells,and is associated with the clinical pathological characteristics of patients.Silencing HOXC13-AS can significantly inhibit the proliferation and migration of head and neck tumor cells.

Metachromatic leukodystrophy (MLD) is an inherited disease caused by a deficiency of the enzyme arylsulfatase A (ARSA). Lentivirus-modified autologous hematopoietic stem cell gene therapy (HSCGT) has recently been approved for clinical use in pre and early symptomatic children with MLD to increase ARSA activity. Unfortunately, this advanced therapy is not available for most patients with MLD who have progressed to more advanced symptomatic stages at diagnosis. Patients with late-onset juvenile MLD typically present with a slower neurological progression of symptoms and represent a significant burden to the economy and healthcare system, whereas those with early onset infantile MLD die within a few years of symptom onset. We conducted a pilot study to determine the safety and benefit of HSCGT in patients with postsymptomatic juvenile MLD and report preliminary results. The safety profile of HSCGT was favorable in this long-term follow-up over 9 years. The most common adverse events (AEs) within 2 months of HSCGT were related to busulfan conditioning, and all AEs resolved. No HSCGT-related AEs and no evidence of distorted hematopoietic differentiation during long-term follow-up for up to 9.6 years. Importantly, to date, patients have maintained remarkably improved ARSA activity with a stable disease state, including increased Functional Independence Measure (FIM) score and decreased magnetic resonance imaging (MRI) lesion score. This long-term follow-up pilot study suggests that HSCGT is safe and provides clinical benefit to patients with postsymptomatic juvenile MLD.

To investigate the protective effects and underlying mechanisms of Qin-Zhu-Liang-Xue decoction (QZLX) in atopic dermatitis (AD) and glucocorticoid resistance, we conducted a single-blinded, randomized controlled clinical trial to evaluate the efficacy and safety of this concoction. Network pharmacology analysis was performed and validated through clinical studies. The efficacy, safety, and mechanism of action of QZLX and glucocorticoid receptor (GR) α recombinant protein were assessed in AD mice induced by 2,4-dinitrofluorobenzene (DNFB). Correlation analysis was performed to determine the clinical relevance of GRα. The trial demonstrated that patients who received QZLX showed considerable improvements in their Scoring Atopic Dermatitis (SCORAD) and Dermatology Life Quality Index (DLQI) scores compared with those who received mizolastine at week 4. Network pharmacological analysis identified GRα as a key target for QZLX in AD treatment. QZLX administration increased the serum GRα expression in AD patients, alleviated AD symptoms in mice, decreased inflammatory cytokine expression, and increased GRα expression without affecting liver or kidney function. In addition, GRα recombinant protein improved AD-like skin lesions in DNFB-induced mice. A negative correlation was observed between GRα expression and clinical parameters, including SCORAD, DLQI, and serum IgE levels. QZLX alleviates AD symptoms through the upregulation of GRα and thus presents a novel therapeutic strategy for the prevention of glucocorticoid resistance in AD management.

Exploring the variability of the intestinal flora of patients with hepatic blastocysticercosis and searching for members of the intestinal microflora that may play a role in the disease process by means of macro-genome sequencing technology. A case-control study was used to include fecal samples from patients with hepatic vesicular schistosomiasis admitted to Qinghai Provincial People′s Hospital between October 2023 and January 2024 and individuals attending health checkups. The experimental group (AE group) consisted of 10 patients with liver vesicular schistosomiasis and the control group (NC group) consisted of 9 individuals attending health checkups. Macrogenomic sequencing was performed on these two groups of samples using the Illumina Novaseq 6000 sequencing platform, using fastp (v0.20.1) to remove junctions, and bbmap (v38.93-0) to remove the hosted sequences, followed by sequence splicing using MEGAHIT (v1.2.9), and then using prodigal (v2.6.3) to The spliced scaffold was subjected to ORF prediction and translated into amino acid sequences, followed by the construction of a non-redundant gene set using MMSeqs2 (v13.45111), and finally compared with the non-redundant gene set using salmon (v1.8.0). Species were annotated by the non-redundant database, species abundance was calculated in each sample, and the two sets were tested using Wilcoxon rank sum test. Finally, the differences in intestinal flora between the two groups were statistically analyzed using linear discriminant analysis, and the correlation between the differential intestinal flora and clinical indicators was analyzed using redundancy analysis (RDA). The results showed that the effective data volume of each sample was distributed from 10.41 to 12.46 G. The number of ORFs in the de-redundantly constructed gene catalogue (non-redundant gene set) was 4 951 408, and the annotation rate of the non-redundant genes was 97.97% when compared with the NR database. The ages of the study subjects in the two groups were (44.78±4.58) years in the NC group and (42.90±10.44) years in the AE group, and the difference was not statistically significant ( t=0.530, P=0.476). The two groups were matched for body mass index (BMI) ( t=2.368, P=0.142), gender ( χ2=0.200, P=0.655), and dietary habits. There was no statistically significant difference in alpha diversity in the AE group (ACE index, t=0.942; chao1 index, t=0.947; shannon index, t=0.813, the simpson′s index, t=0.613, P>0.05), while beta diversity analysis showed significant differences in the overall structure of the two communities (Stress=0.054 5). A total of 120 species were annotated at the phylum level, of which two differed. While 1 736 species were annotated at the genus level, 69 were different, and 309 were different at the species level. The AE group ranked the top 6 in terms of abundance of Anaplasma, Escherichiaceae, Clostridium, Alternaria, Ruminalia, and Treponema spp. at the genus level; whereas, Segatella, Prevotella, E. faecalis, Rossella, and beneficial rod-shaped bacteria were more abundant in the NC group. There were differences in the abundance and diversity of intestinal flora between the two groups, and the structure of community composition was significantly different. Statistical results by linear discriminant analysis (LDA) showed that LDA scores >2 in the NC group included beneficial bacillus spp. and E. faecalis spp. in young infants, etc. LDA scores >2 in the AE group at the mid-species level included Clostridium polterococcus, unknown microorganisms in the genus Clostridium intestinalis, Hathaway′s Henkett′s bacillus, and Clostridium oryzae in the genus Clostridium refractory to culture and small Clostridium spp. in the AE group. Clostridium intestinalis. The RDA results showed a negative correlation between beneficial rod genera and liver function indices, and a positive correlation between Clostridium intestinalis genera and liver function indices. In conclusion, patients with hepatic blastomycosis have altered intestinal flora abundance and diversity, with significant structural changes in community composition and differences in several genera, including Mycobacterium anisopliae and Clostridium intestinalis, and imbalances in the intestinal flora may affect hepatic function by influencing intestinal metabolites and may have an impact on the development of hepatic blastomycosis, a finding that warrants further in-depth study.

Objective:To investigate the in vitro bacteriostatic effect of ethyl alcohol extract of Moutan Cortex (EAEMC) on Candida tropicalis and its effect on virulence factors, including aspartic protease, hemolysin, phospholipase, esterase, lipase activities and biofilm. Methods:EAEMC powder was obtained by ultrasonic extraction, decompression concentration and lyophilization; the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of EAEMC on 21 clinical strains and one standard strain of Candida tropicalis were determined by microdilution. Five extracellular enzyme activities of Candida tropicalis and the effect of EAEMC on them were detected by the plate assay, and the results were analyzed by ANOVA. The biofilm model of Candida tropicalis was constructed in vitro, and the inhibition rate of EAEMC on Candida tropicalis biofilm was evaluated using the thiazolyl blue (MTT) method. Results:The MIC of EAEMC against Candida tropicalis BNCC335988 was 12.5 g/L and the MBC value was 25 g/L, while for the clinical strains, the MIC was 12.5-25 g/L and the MBC was 25-50 g/L. Aspartic protease, esterase and hemolytic activities of Candida tropicalis were positive, but phospholipase and lipase showed negative activities. At a concentration of 1/2 MIC of EAEMC, the aspartic protease and hemolytic activities of Candida tropicalis were completely inhibited the aspartic protease and hemolytic activities of Candida tropicalis were completely inhibited and the esterase activity was completely inhibited at a concentration of MIC of EAEMC. The inhibition of Candida tropicalis BNCC335988 biofilm by EAEMC reached more than 70% at a concentration of 2MIC, more than 80% at a concentration of 4MIC, and more than 90% at a concentration of 8MIC. Conclusion:EAEMC can achieve bacteriostatic effects by reducing the aspartic protease, esterase and hemolysin activities of Candida tropicalis, as well as inhibiting biofilm formation.

Objective:To systematically evaluate studies validating the performance of the Global Leadership Initiative on Malnutrition (GLIM) in diagnosing malnutrition.Methods:Seven Chinese and English databases including Embase, Web of Science (WOS), PubMed, CINAHL, Cochrane Library, SinoMed, CNKI, Wanfang Data, and VIP Database were searched for articles on the validation of GLIM criteria published between September 2018 and September 2024. Two researchers independently performed literature screening and data extraction. The concurrent and predictive validity of the criteria was analyzed.Results:A total of 136 papers were included for analysis. The GLIM criteria for diagnosing malnutrition had a sensitivity of 77%, a specificity of 87%, and an area under the curve (AUC) of 0.90. Malnutrition diagnosed by the GLIM criteria predicted prolonged hospital and intensive care unit (ICU) stays, increased readmission and complication rates (both overall and infectious), reduced survivals (median, overall, and disease-free), and increased in-hospital and follow-up mortalities. Both moderate and severe malnutrition predicted decreased overall survival. However, only three studies analyzed the impact of nutritional therapy on the clinical outcomes of malnourished patients.Conclusions:The GLIM criteria accurately differentiate malnutrition and are a valid predictive tool of clinical outcomes. However, the validity criteria in these validation studies were questionable, along with high methodological heterogeneity. Furthermore, there is a lack of studies validating the role of nutritional therapy in improving the clinical outcomes of malnourished patients.
