Objective To investigate the impact of simvastatin on blood lipid and the incidence of atrial fibrillation and ischemic-related events in patients with acute myocardial infarction accompanied by paroxysmal atrial fibrillation. Methods One hundred and three patients with acute myocardial infarction and paroxysmal atrial fibrillation were selected as subjects, and were divided into a simvastatin group and a control group. Forty-five patients were in the simvastatin group, who took simvastatin 20mg/d orally for 18 months; fifty-eight patients were in the control group, and received conventional therapy except for statins. All patients were followed up for 18months. The level of blood lipid, recurrence rate of paroxysmal atrial fibrillation, incidence rate of persistent or permanent atrial lipids did not change significantly in the control group (P＞0.05); concentrations of total cholesterol (TC) and low density lipoprotein five patients during 18 months follow-up in the simvastatin group (11.1%), whereas it occurred in 14 patients of the control group(24.1%, P＜0.05); the occurrence rate of persistent or permanent atrial fibrillation in the simvastatin group was 4.4%, which was lower than (6.6%), two rehospitalizations for deterioration of coronary heart diseases (4.4%), three cardiac deaths (6.6%), and one cerebral stroke (2.2%), which was lower evidently than in the control group (41.4%, P＜0.05). Conclusions Simvastatin can not only decrease the levels of serum TC and LDL-C but also prevent the occurrence of atrial fibrillation and ischemic-related events.

Objective:To investigate the efficacy and safety of cedilanid in the treatment of severe pneumonia in infants and the value of preventing heart failure.Methods:A total of 80 children with severe pneumonia admitted to Dezhou Maternal and Child Health Hospital from January 2019 to December 2020 were selected and randomly divided into the control group and the observation group, with 40 cases in each group. The control group received comprehensive treatment, while the observation group was treated with cedilanid (0.01 mg/kg, one-time intravenous injection) on the basis of the control group. The efficacy of both groups was observed after 5 d of treatment. The incidence of heart failure, correction time of heart failure, improvement time of symptoms and signs, and length of hospitalization time were compared between the two groups; the inflammatory markers, myocardial markers and arterial blood gas indexes were compared between the two groups before and after the treatment.Results:The total effective rate in the observation group was higher than that in the control group, and the incidence of heart failure in the observation group was lower than that in the control group: 90.0% (36/40) vs. 72.5% (29/40), 32.5%(13/40) vs. 10.0%(4/40), the differences were statistically significant ( &chi;2 = 4.02, 4.10, P<0.05). The improvement time of symptoms and signs (restlessness elimination, respiratory improvement, heart rate improvement and disappearance of rhonchus in lung) in the observation group were less than those in the control group ( P<0.05). The levels of procalcitonin (PCT) and N-terminal pro-brain natriuretic peptide (NT-ProBNP), myocardial troponin I(cTnI), and creatine kinase isoenzyme (CK-MB) in the observation group after treatment were lower than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. The levels of oxygen partial pressure (PaO 2), blood oxygen saturation (SaO 2) and oxygenation index (PaO 2/FiO 2) in the observation group after treatment were higher than those in the control group: (6.15 ± 1.03) μg/L vs. (10.85 ± 2.12) μg/L, (112.02 ± 30.09) ng/L vs. (215.39 ± 55.08) ng/L, (0.68 ± 0.17) μg/L vs. (1.12 ± 0.34) μg/L, (19.05 ± 6.11) U/L vs. (28.97 ± 7.82) U/L, P<0.05. Conclusions:Early application of small dose of cedilanid in infants with severe pneumonia can effectively reduce the occurrence of heart failure, improve the clinical symptoms and blood gas indicators, with significant curative effect, which is worthy of promotion.

Objective: To explore the relationship between visual acuity and physical fitness of university freshmen, so as to provide reference for myopia prevention and control for freshmen. Methods: From October to November 2022, 2 160 college freshman without majoring in public safety administration, selected from Guangxi Police College in 2022 by using the stratified cluster random sampling method, were reviewed for the results of visual acuity test and physical fitness scores. The physical fitness indices were evaluated by using the Z scores of physical fitness test scores, and the strength of association between the level of physical fitness index and myopia was analyzed by using Logistic regression model. Results: Among 2 160 college freshman without majoring in public safety administration, 917 (42.5%) students were diagnosed screening myopia, including 66 (3.1%) cases of high myopia, 383 (17.7%) cases of moderate myopia and 468 (21.7%) cases of mild myopia. The differences in the distribution of visual acuity tests among students with different physical fitness indices, body mass index, and gender were statistically significant ( Z/H=54.50, 49.53, 15.51, P <0.01). Low level and low middle level physical fitness indices were associated with screening myopia among freshmen[ OR (95% CI )=2.81(1.93-4.08),1.87(1.38-2.54)], and low level physical fitness indexes were associated with high myopia [ OR (95% CI )=7.22(2.33-22.32)] ( P <0.01). Conclusions Screening myopia among college freshman without majoring in public safety administration is related to physical fitness, and low level and low middle level physical fitness index are risk factors for myopia. Improving the level of physical fitness might be effective in preventing myopia.

Tree shrew is a novel and high-quality experimental animal model. In this study, the real-time polymerase chain reaction methods were established to detect infection-related cytokines interleukin-6 (IL-6), IL-8, IL-10, IL-17A, interferon-γ (IFN-γ) and housekeeping gene glyceraldehyde-phosphate dehydrogenase ( ) of tree shrew. The results indicated that the establised methods had good specificity. The high point of the linear range of these reagents reached 1 × 10 copies, and the low points ranged from 10 copies (IL-6, IL-17A), 100 copies (IL-10, ) to 1 000 copies (IL-8, IFN-γ). In this interval, the linear correlation coefficient of each reagent was greater than 0.99. The lowest detectable values of IL-6, IL-8, IL-10, IL-17A, IFN-γ and were 8, 8, 4, 8, 128 and 4 copies, respectively. The results showed that the established detection methods had good specificity, sensitivity and wide linear range. The methods were suitable for detection of multiple concentration range samples, and could be used for the subsequent studies of tree shrew cytokines.
