The aim of this study was to explore the associations of interleukin-1β (IL-1β) and IL-6 gene polymorphisms with the pathogenesis of Parkinson's disease.
A total of 200 patients with Parkinson's disease in our hospital were collected as the disease group. Meanwhile, 200 healthy subjects were taken as the control group. Peripheral blood samples were drawn from all research subjects. The polymorphic regions of IL-1β and IL-6 were amplified via polymerase chain reaction (PCR). Moreover, the polymorphisms were detected and analyzed, followed by further analysis based on the changes in gene expressions and Hoehn-Yahr grade of patients.
The allele distributions at IL-1β rs571556428 (p=0.015) and IL-6 rs543214973 (p=0.012) were statistically different between control group and disease group. In disease group, the G allele frequency at IL-1β rs571556428 and T allele frequency at IL-6 rs543214973 were significantly higher (p<0.05). Genotype distributions at IL-1β rs572292175 (p=0.017) and rs571556428 (p=0.000e polymorphism at IL-1β rs571556428 was significantly correlated with the grade of Parkinson's disease (p=0.000). Parkinson's disease was in a higher grade (grade 4-5) in patients with AA genotype, whereas in a lower grade (grade 1-2) in patients with GG and AG genotypes.
IL-1β and IL-6 gene polymorphisms are significantly associated with the pathogenesis of Parkinson's disease.

To explore the mechanism of TLR7 mediating NF-κB signaling pathway on the pathogenesis of bronchial asthma in mice and the intervention effect of IFN-γ in the process.
The experimental animals were 70 C57BL/6J female mice of clean grade, which were divided into 7 groups according to different treatment protocols, including Normal group, Asthma group, Model+1-MT group, Model+IFN-γ group, Model+TLR7 agonist group, TLR7 deficient group, and Model+TLR7 deficient group. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of lung tissues. The positive expression rates of TLR7, p-IKKα and NF-κBp65 were detected by immunohistochemistry. bronchoalveolar lavage fluid (BALF) cells were classified and counted. The contents of interleukin (IL)-4, IL-10, IL-12 and interferon (IFN)-γ in BALF supernatant were detected by enzyme-linked immunosorbent assay (ELISA). Following isolation, culture and plasmid construction of airway smooth muscle cells (ASMCS) from normal mice and asthmatic mice, cells es cell apoptosis in asthmatic mice. Besides, IFN-γ can exert a protective role in suppressing the progression of inflammation in asthma.
The incidence of SAP (stroke-associated pneumonia) is high in integrated ICU (Intensive Care Unit), and it might result in sepsis, which exacerbates the clinical outcome and increases mortality. It is necessary to investigate the epidemiological features of post-stroke infection and sepsis, identify the risk factors and analyze the prognosis.
We retrospectively analyzed the data of 329 patients with cerebral infarction or cerebral hemorrhage, from seven tertiary university hospitals in Suzhou, Jiangsu Province, between January 1, 2016, and December 31, 2016. Basic demographic and clinical data including common health evaluation, stroke severity, microbiological parameters, surgical interventions and treatments were recorded for the analysis. Daporinad SAP was diagnosed according to the criteria and recommendation from American Heart Association (AHA).
188 (66.4%) patients suffered pneumonia, 124 patients were diagnosed as SAP. Compared with SAP, patients with non-SAP pulmonary infection had prolonged mechanical vrm neurological function is relatively poor. The definition of stroke-associated pneumonia has implications for the classification of clinical infections, the prediction of possible pathogenic pathogens, and the guidance of anti-infective treatment.
The incidence of pulmonary infection after stroke in the integrated ICU is high, and it is easy to be complicated with sepsis, prolonging the mechanical ventilation time, central venous catheter indwelling time and hospitalization time, and the prognosis of long-term neurological function is relatively poor. The definition of stroke-associated pneumonia has implications for the classification of clinical infections, the prediction of possible pathogenic pathogens, and the guidance of anti-infective treatment.Anderson-Fabry disease (FD) is a rare genetic, progressive, and multi-systemic condition, with X-linked inheritance. This is caused by pathogenic variants in the GLA gene, coding for the lysosomal enzyme called alpha-galactosidase A (aGLA), responsible for the cleavage of globotriaosylceramide (Gb3). The reduced or absent activity of aGLA causes the intracellular accumulation of Gb3, particularly in smooth and endothelial muscle cells, which causes cellular dysfunction. The main organs involved are the central nervous system, heart, and kidneys. However, being a ubiquitous enzyme, FD disease must be considered a systemic disease involving the peripheral nervous system, ocular and audio-vestibular systems. Also, the vascular district is damaged but the pathophysiology of vasculopathy in FD is not yet entirely understood. In literature, many vascular diagnostic tests were used to evaluate this specific involvement in FD, i.e., carotid intima media thickness (cIMT), arterial stiffness (AS), flow-mediated dilation (FMD) and atherosclerotic plaques; evaluation of vascular calcifications in FD patients is not presently available. In this review, we examined the current available literature on vascular aspects in FD. Moreover, we presented our global vascular evaluation, based on Radio Frequency Duplex Ultrasound (RF-DU), plaques, and vascular calcifications, to apply to FD patients.
The current study investigates the effect of the innovative phosphorothioate modified backbone locked nucleic acid (LNA) of microRNA-103 (miR-103) specifically designed for systemic delivery in the silencing of miR-103 in experimentally induced myocardial infarction (MI). MicroRNA-103 is a small non-coding RNA which regulates Fas-associated protein with death domain (FADD) gene expression, which is a negative regulator for necroptosis occurs during the progression of MI.
Experimental male mice were allocated into three groups; the first group received normal saline, the second group was injected with isoprenaline and served as the infarcted control, while the third group was treated with LNA miR-103 power inhibitor before isoprenaline injection. Blood and heart samples were used for biochemical analysis of miR-103, FADD, receptor-interacting protein kinase (RIPK), nuclear factor-κβ, tumor necrosis factor-α, interleukin-6, troponin-I and creatine kinase-MB (CK-MB) as well as the histological examination of heart tissue.
The treated mice showed marked improvement in the troponin-I and CK-MB levels with almost normal histological structure of heart tissue. Significant inhibition of miR-103 accompanied by increased FADD expression and markedly decreased expression of the other biomarkers were observed in the hearts of the treated mice.
LNA miR-103 inhibitor is a potent cardioprotective agent and can be a promising treatment against MI through targeting FADD/RIPK pathway.

To explore the effect of integrin β3 (ITGB3) gene silencing mediated mitogen-activated protein kinase (MAPK) signaling pathway on myocardial ischemia-reperfusion injury (MIRI) in mice.
MIRI mice model was established, and myocardial tissues of MIRI mice and sham operation group mice were extracted. Hematoxylin-Eosin (HE) staining was used to observe the pathological changes of myocardial tissue; terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) staining was used to detect the apoptosis of myocardial cells; ELISA method was used to detect the levels of interleukin (IL)-1, IL-6, and tumor necrosis factor (TNF)-α in the two groups. The infarct size was measured by TTC staining. Myocardial cells of MIRI model mice were isolated and cultured, and then grouped and transfected. The cells were transfected with the grouping of MIRI group, negative control (NC) group, MAPK signal pathway agonist Anisomycin group, MAPK signal pathway inhibitor SB203580 group, ITGB3-siRNA group, SB2promote the proliferation of mouse myocardial cells, inhibit myocardial cell apoptosis and inflammatory reaction, and thus have protective effect on MIRI in mice.
Silencing ITGB3 gene expression can promote the activation of MAPK signaling pathway, elevate the phosphorylation of GSK-3β and Cx43 in the downstream, promote the proliferation of mouse myocardial cells, inhibit myocardial cell apoptosis and inflammatory reaction, and thus have protective effect on MIRI in mice.
The aim of this study was to explore the role of pioglitazone (PIO), a peroxisome proliferator-activated receptor-gamma (PPARγ) agonist, in cardiac fibrosis of diabetic mice.
A total of 60 adult male C57/B6 mice were divided into 3 groups using a random number table, namely, control group (Sham group, n=20), diabetic cardiomyopathy group (DCM group, n=20), DCM + PIO group (n=20). Streptozocin (STZ) was injected into mice at a dose of 125 mg/Kg to induce the model of diabetes in vivo. After successful induction, mice in DCM + PIO group were intragastrically given PIO at 10 mg/kg/d once a day for 6 weeks. Meanwhile, those in Sham group and DCM group were given the same volume of normal saline. After 6 weeks, ejection fraction % (EF%), fraction shortening % (FS%) and heart rate of mice in each group were examined via echocardiography. Picrosirius red (PSR) staining assay was conducted to detect collagen deposition in myocardial tissues of mice in each group. The protein expression level of PPARγ in mouse myocardial tissues in each group was measured through Western blotting and immunohistochemical staining assays.
