ABSTRACT
Objective:To investigate the correlation between serum inflammatory markers and carotid plaque and its stability in patients with acute ischemic stroke (AIS).Methods:Patients with AIS admitted to Liaocheng Third People’s Hospital from June 2021 to April 2022 were prospectively enrolled. The demographic and relevant clinical data were collected. Color Doppler ultrasound was used to detect carotid artery plaques. The patients were divided into unstable plaque group, stable plaque group and non-plaque group according to plaque characteristics. The levels of serum hypersensitive C-reactive protein (hs-CRP), serum amyloid A (SAA) and interleukin (IL) -6 were detected and compared. Multivariate logistic regression analysis was used to determine the independent risk factors for carotid plaque and its stability. Results:A total of 201 patients with AIS were enrolled, including 87 patients (43.30%) in the non-plaque group, 57 (28.35%) in the stable plaque group, and 57 (28.35%) in the unstable plaque group. The proportion of patients with hypertension and previous stroke history, and hs-CRP, SAA and IL-6 levels in the unstable plaque group was significantly higher than those in the stable plaque group and the non-plaque group (all P<0.05). Multivariate logistic regression analysis showed that after adjusting for other confounding factors, the increased IL-6 level (odds ratio [ OR] 1.174, 95% confidence interval [ CI] 1.049-1.314; P=0.005) was an independent risk factor for the existence of stable plaques, while the previous stroke history ( OR 3.172, 95% CI 1.123-8.957; P=0.029) and the increased IL-6 level ( OR 1.367, 95% CI 1.107-1.687; P=0.004) were the independent risk factors for the existence of unstable plaques. Conclusion:The serum IL-6 level in patients with AIS increase significantly, which is closely associated with the formation and stability of carotid plaques.
ABSTRACT
A case of limbic encephalitis with positive anti-zinc finger protein 4 (ZIC4) antibody and anti-Hu antibody was reported. A middle-aged female was admitted to hospital for two months because of memory loss and unstable walking. The main manifestations were cognitive decline, ataxia and sensory disturbance of both lower extremities. The main diagnosis was limbic encephalitis, complicated with subacute cerebellar degeneration and subacute sensory neuron disease, which was consistent with paraneoplastic nervous system syndrome. Magnetic resonance imaging showed abnormal signals in bilateral temporal lobe and hippocampus, electromyography showed sensory nerve damage, blood and cerebrospinal fluid anti-ZIC4 antibody and Hu antibody were both positive, and no tumor was found. It is speculated that there may be potential tumors and need to be followed up and monitored. This rare case is reported to attract the attention of clinicians.
ABSTRACT
A case of late-onset methylmalonic aciduria combined with hyperhomocysteinemia (cblC type) is reported. The main manifestations were the reduction of intelligence,the instability of walking,and the inability to take care of oneself,with secondary cerebral hemorrhage. The effect of treatment was good. MMACHC gene mutation detection showed exon1 deletion, indicating that delExon1 is one of the causes of late onset methylmalonic aciduria, cblC type.
ABSTRACT
Objective To study the etiological agent of hand, foot and mouth disease ( HFMD) and the genetic characteristics of coxsackievirus A16 ( CVA16 ) strains isolated from clinical specimens of patients with HFMD in Liaocheng city in 2013.Methods Throat swab and stool specimens were collected from patients with HFMD in the disease surveillance hospitals in Liaocheng city from January to December 2013.Samples pos-itive for CVA16 strains were screened out for the isolation of virus strains with rhabdomyosarcoma ( RD) cells and Vero cells.The entire VP1 coding regions of 9 randomly selected CVA16 isolates were amplified and se-quenced.BioEdit and MEGA4 softwares were used for homology analysis.A phylogenetic tree among the 9 CVA16 isolates and 56 CVA16 representative strains of known genotypes and subgenotypes was constructed.Re-sults The results of PCR analysis showed that 747(77.73%) out of 961 specimens were positive for HFMD and among them, 74 samples (9.91%) were positive for EV71 strains, 130(17.40%) were CVA16 strains and 543(72.69%) were other enterovirus strains.The 9 CVA16 strains clustered into the B2b evolution branch of B genotype with the representative strains, sharing 97.7%to 100%homologies in nucleotide sequences and 99.3%to 100%in amino acid sequences.Conclusion Although EV71 and CVA16 strains were identified, other enteric viruses were the predominant pathogens causing HFMD in Liaocheng city in 2013.The CVA16 iso-lates belonged to B2b subgenotype.The pathogen spectrum of HFMD had already changed.It is necessary to strengthen the surveillance for EV71, CVA16 and other enteric viruses and understand their genetic characteriza-tions, which would be of great significance for the prevention and control of HFMD.
ABSTRACT
PURPOSE: Allergic rhinitis (AR) is an inflammatory disorder of the upper airway. Exosomes or extracellular vesicles are nanosized vesicles of endosomal origin released from inflammatory and epithelial cells that have been implicated in allergic diseases. In this study, we characterized the microRNA (miRNA) content of exosomes in AR. METHODS: Extracellular vesicles were isolated from nasal mucus from healthy control subjects (n=10) and patients with severe AR (n=10). Vesicle RNA was analyzed by using a TaqMan microRNA assays Human Panel-Early Access kit (Applied Biosystems, Foster City, CA, USA) containing probes for 366 human miRNAs, and selected findings were validated with quantitative RT-PCR. Target prediction and pathway analysis for the differentially expressed miRNAs were performed using DIANA-mirPath. RESULTS: Twenty-one vesicle miRNAs were up-regulated and 14 miRNAs were under-regulated significantly (P<0.05) in nasal mucus from AR patients when compared to healthy controls. Bioinformatic analysis by DIANA-mirPath demonstrated that 32 KEGG biological processes were significantly enriched (P<0.05, FDR corrected) among differentially expressed vesicle miRNA signatures. Among them, the B-cell receptor signaling pathway (P=3.709E-09), the natural killer cell-mediated cytotoxicity (P=8.466E-05), the T-cell receptor signaling pathway (P=0.00075), the RIG-I-like receptor signaling pathway (P=0.00127), the Wnt signaling pathway (P=0.00130), endocytosis (P=0.00440), and salivary secretion (P=0.04660) were the most prominent pathways enriched in quantiles with differential vesicle miRNA patterns. Furthermore, miR-30-5p, miR-199b-3p, miR-874, miR-28-3p, miR-203, and miR-875-5p, involved in B-cell receptor and salivary secretion signaling pathways, were selected for validation using independent samples from 44 AR patients and 20 healthy controls. MiR-30-5p and miR-199b-3p were significantly increased in extracellular vesicles from nasal mucus when compared to healthy controls, while miR-874 and miR-28-3p were significantly down-regulated. In addition, miRNA-203 was significantly increased in AR patients, while miRNA-875-5p was found to be significantly decreased in AR patients. CONCLUSIONS: This study demonstrated that vesicle miRNA may be a regulator for the development of AR.

Objective To assess the value of joint detection of serum cysteine proteinase inhibitors C (sCys-C),urinary kidney injury molecule 1 (uKIM-1),urinary neutrophil gelatinase-associated lipocalin(uNGAL) and urinary interleukin 18 (uIL-18) for early diagnosis of acute kidney injury (AKI) in critically ill patients.Methods A total of 256 adult patients who stayed Intensive Care Unit for 24 hours in the Third People's Hospital of Liaocheng between Aug 2011 and Dec 2012 were enrolled.According to Kidney Injury Net(AKIN) work,the patients were divided into non-AKI group and AKI group (including state 1,2 and 3).The concentrations of urine NGAL,KIM-1,IL-18 and serum sCys-C were measured.The diagnosis value of four biomarkers joint detection and single detection for AKI were analyzed with the receiver operating characteristic (ROC) curve and the area under curve (AUC).Results (1) The levels of uNGAL,uKIM-1,uIL-18 and sCys-C were higher in patients with AKI than the patients with no AKI (P ＜ 0.01).(2) The area under curves of uNGAL,uKIM-1,uIL-18,sCys-C and joint detection were 0.742,0.871,0.803,0.703,0.925 respectively.(3) The sensitivity and specificity of parallel tests and serial tests of four biomarkers were 97.9％,62.8％,64.3％ and 96.2％ respectively.There were significant differences of sensitivity or specificity between single test and joint tests.Conclusions The urine NGAL,KIM-1,IL-18 and serum Cys-C are sensitive indexes for the early diagnosis of acute kidney injury.Joint detection has high value for early diagnosis of AKI.
