STAF score predict paroxysmal atrial fibrillation in patients with recurrent acute ischemic stroke / 国际脑血管病杂志

Objective:To investigate the predictive value of STAF (score for the targeting of atrial fibrillation) score for paroxysmal atrial fibrillation (PAF) in patients with recurrent acute ischemic stroke.Methods:Consecutive patients with recurrent acute ischemic stroke hospitalized in the Department of Neurology, Huizhou Municipal Central Hospital from January 2014 to January 2020 were enrolled retrospectively. All patients were divided into a sinus rhythm (SR) group and a PAF group. PAF was defined as no PAF during the last stroke hospitalization or after discharge, and PAF was found by routine ECG, ambulatory ECG or long-term ECG monitoring after this recurrent acute ischemic stroke. Multivariate logistic regression analysis was used to evaluate the independent related factors of PAF in patients with recurrent acute ischemic stroke. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of STAF for PAF in patients with recurrent acute ischemic stroke. Results:A total of 234 patients with recurrent acute ischemic stroke were enrolled, including 174 males (74.4%), aged 67.15±10.63 years, and 199 (85.0%) in the SR group and 35 (15.0%) in the PAF group. Univariate analysis showed that the proportion of patients in age >62 years old (94.3% vs. 63.8%; χ2=12.777, P<0.001) and left atrial enlargement (54.3% vs. 11.1%; χ2=40.379, P<0.001) of the PAF group was significantly higher than those of the SR group. Multivariate logistic regression analysis showed that age (odd ratio [ OR] 1.071, 95% confidence interval [ CI] 1.028-1.114; P=0.001) or age >62 years ( OR 17.512, 95% CI 2.881-106.453; P=0.002), left atrial enlargement ( OR 17.511, 95% CI 6.298-48.687; P<0.001), absence of vascular etiology ( OR 8.562, 95% CI 2.534-28.923; P=0.001), STAF score ( OR 2.715, 95% CI 1.969-3.744; P<0.001) and STAF score ≥5 ( OR 12.714, 95% CI 5.636-28.681; P<0.001) were independently associated with PAF. ROC curve analysis showed that the area under the curve of STAF for predicting PAF in patients with recurrent acute ischemic stroke was 0.848 (95% CI 0.779-0.917), and the sensitivity and specificity of STAF ≥5 for predicting PAF were 58.1% and 89.4%, respectively; the area under the curve for predicting PAF in patients with recurrent ischemic stroke of undetermined cause was 0.809 (95% CI 0.663-0.956), and the sensitivity and specificity of STAF ≥5 for predicting PAF were 53.8% and 91.3%, respectively. Conclusions:PAF is likely to exist in patients with recurrent acute ischemic stroke and aged >62 years, left atrial enlargement and absence of vascular etiology. STAF has medium predictive value for PAF in patients with recurrent acute ischemic stroke, but the sensitivity is not high.

Influence of Roy adaptation mode and resistance training on cardiac function and life quality of patients with chronic heart failure / 现代临床护理

Objective To explore the influence of Roy adaptation mode and resistance training on cardiac function and life quality of patients with chronic heart failure. Methods One hundred patients with chronic heart failure in our hospital cardiovascular department were enrolled in the study. All patients received conventional treatment of chronic heart failure. They were equally divided into the control group and the observation group using random digit grouping method. The control group received conventional nursing mode and observation group received Roy adaptation mode joint resistance training. The cardiac function and life quality of two groups were compared after two months. Result After three months′intervention, each index of cardiac function was significantly better than that of the control group ( P < 0 . 01 ) , 6 minutes waking distance of the observation group was significantly longer than that of the control group ( P < 0 . 01 ) , and the life quality score was significantly higher than that of the control group (P<0.01). Conclusion The Roy adaption mode and resistance training can improve heart function and the overall quality of life of the patients with chronic heart failure.

Analysis of OCRL gene mutation in a male infant with Lowe syndrome / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To identify pathological mutation in a Chinese male infant featuring oculocerebrorenal syndrome (also called Lowe syndrome).</p><p><b>METHODS</b>Clinical data of the patient were collected. DNA was extracted from peripheral blood of the infant and his parents. All of the 24 exons and intron-exon splice sites of OCRL gene were amplified with PCR. Mutations were detected by direct sequencing the PCR products.</p><p><b>RESULTS</b>The infant was found to have carried a c.1499G>A (p.R500Q) mutation in exon 15 of the OCRL gene, which was transmitted from his mother, who was heterozygous for the same mutation. The c.1499G>A mutation, discovered in Chinese population for the first time, has been reported to cause severe Lowe syndrome in other ethnic populations.</p><p><b>CONCLUSION</b>The c.1499G>A mutation of the OCRL gene is probably responsible for the disease in the patient. Further study of this mutation may facilitate delineation of the genotype-phenotype correlation of this disease.</p>

Effects of PI3K/Akt/NF-κB signal pathway on FSH facilitation on cell proliferation and invasion by human epithelial ovarian cancer / 中华妇产科杂志

ObjectiveTo explore the effects of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/nuclear factor-kappa B (NF-κB) signal pathway on the process of follicle-stimulating hormone (FSH) facilitating cell proliferation and invasion in human epithelial ovarian cancer. Methods Ovarian cancer cell lines SKOV3 and 3AO were cultured to exponential phase,then assigned to control group,FSH group,LY294002 group and FSH + LY294002 group,respectively.Cells were treated with different concentration of FSH and LY294002,respectively.The effects of FSH on cell proliferation were observed by methylthiazolyl tetrazolium (MTT).Morphological changes were observed by phase contrast microscope.The ability of cell invasion was investigated by transwell invasion assay.The expression of FSH receptor (FSHR),Akt1/2,phosphorylated-Akt (p-Akt) and NF-κB p65 protein were detected by western blot.Results( 1 ) FSH could promote the proliferation of SKOV3 and 3AO cells.When the cells were treated with 40 U/L FSH for 48 hours (SKOV3) and 24 hours (3AO),compared with those in control groups,they reached the highest proliferation rate (P ＜ 0.05 ),respectively.(2) The morphology of SKOV3 and 3AO cells in four groups:in control group,SKOV3 cells were short spindle and 3AO cells were long spindle,the nuclei of them were both roundness or oval,the cytoplasm were bright.In FSH group,the cells changed to slightly longer or polygonal,they were full in shape,meanwhile,the cell intensity were higher than control group.In LY294002 group,some cells changed from spindle to round,and began to shrink.The cell intensity diminished.The morphology of FSH + LY294002 group was similar with control group,but the cell intensity was lower than that in FSH group.(3)The number of SKOV3 cell that passed through the membrane in control group,FSH group,LY294002 group and FSH + LY294002 group was (26 ± 6),( 118 ± 19),( 18 ± 5) and ( 38 ± 7 ),respectively.The number of 3AO cell was ( 19 ± 4 ),( 134 ± 20),(12 ±3) and (58 ± 11 ),respectively.The results showed that the number of cells in FSH group was significantly higher than that in control group ( P ＜ 0.05 ),while the number of cell in FSH + LY294002 group was significantly fewer than that in FSH group (P ＜ 0.05 ).(4) There was no significant difference in the expression of FSHR and Akt1/2 between FSH group and control group (P ＞ 0.05 ),but FSH increased the expression of p-Akt and the ratio of NF-κB p65 in the nucleus versus cytoplasm in SKOV3 and 3AO cells,there were significant differences compared with control group ( P ＜ 0.05 ).LY294002 reversed the effects of FSH on increasing the expression of p-Akt and the ratio of NF-κB p65 in the nucleus versus cytoplasm,there were significant differences among LY294002 group,FSH + LY294002 group and FSH group (P ＜ 0.05 ).ConclusionThe effects of FSH on proliferation and invasion of ovarian cancer cell lines SKOV3 and 3AO may be realized by regulating the activity of NF-κB in PI3K/Akt signal pathway.
