RESUMO
Objective:To investigate the correlation between EOS level and hormone therapy effect and prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:From January 2016 to June 2018, 120 patients with AECOPD were selected in the Fifth People's Hospital of Datong.According to EOS levels, all patients were divided into two groups, including EOS ≥2% group(56 cases) and EOS<2% group(64 cases). The general clinical data and treatment related indicators of patients with different EOS levels were compared, and the clinical value of EOS level in predicting the risk of severe AECOPD recurrence and death of patients were evaluated.Results:The levels of WBC, N%, NLR and CRP of the EOS≥2% group were significantly lower than those of the EOS<2% group[(6.89±1.16)×10 9/L, (69.08±12.79)%, (3.54±1.16), (5.30±1.18)mg/L vs.(8.45±1.85)×10 9/L, (76.42±16.58)%, (6.08±1.42), (7.43±1.77)mg/L]( t=5.27, 4.81, 4.65, 2.58, all P<0.05). The used time of antibiotics of the EOS≥2% group was significantly shorter than that of the EOS<2% group[8.0(6.0, 10.0)d vs.9.0(7.0, 11.0)d]( U=2.46, P<0.05). The time of hormone therapy and hospitalization time of the EOS≥2% group were significantly shorter than those of the EOS<2% group[9.0(7.0, 11.0)d, 10.0(9.0, 12.0)d vs.11.0(7.0, 13.0)d, 12.0(10.0, 13.0)d]( U=2.79, 2.56, all P<0.05). The proportion of CAT score decreased ≥2 points at 7d after treatment of the EOS≥2% group was significantly higher than that of the EOS<2% group[86.84% vs.68.18%](χ 2=2.84, P<0.05). Logistic regression analysis showed that EOS≥2% was the independent risk factor for severe AECOPD recurrence and death( OR=2.84, 95% CI: 1.49~5.03, P<0.05). There was no relationship between EOS level and death risk ( P>0.05). Conclusion:Serum EOS level can independently predict the clinical effect of hormone therapy and prognosis in patients with AECOPD, and clinicians can make more reasonable clinical treatment plan accordingly.
RESUMO
Oxidative stress is an important factor that can cause aging body, tissue damage and diseases.FoxO3a transcription factor is critical for the regulation of oxidative stress.Recently, there are some reports on the quite complex role of FoxO3a in regulating oxidative stress.Not only can it promote the survival of cells, but also induce cell apoptosis at some oxidative stress conditions.In this paper, the role of FoxO3a in oxidative stress, the possible signal pathway and the potential effect of target FoxO3a for oxidative stress diseases treatment are reviewed.
RESUMO
Objective To analyze the differences between the semi-quantitative RT-PCR and real time quantitative fluorescence RT-PCR assays for detecting XDH/XO mRNA expression in various organ tissues of rhesus monkey, and provide useful reference in methodology of experimental studies.Total RNA was extracted from the myocardium, kidney, testis, skin, and liver tissues, respectively, for detecting XDH/XO mRNA expression in rhesus monkey by semi-quantitative RT-PCR and real time quantitative fluorescence RT-PCR assays.The sensitivity and specificity of the two assays were compared with each other using the same primer sequences and reference genes.Results The expression of XDH/XO mRNA in different organ tissues were detected by both the two PCR assays.The sensitivity of quantitative fluorescence real-time RT-PCR for the XDH/XO mRNA expression in the liver tissue was 39 times higher than that by semi-quantitative RT-PCR.Conclusions Both the quantitative and semi-quantitative fluorescence RT-PCR assays can be used to detect the expression of XDH/XO mRNA in different organ tissues of rhesus monkey.The sensitivity of quantitative fluorescence real-time PCR assay is more sensitive than that of the semi-quantitative RT-PCR assay.
RESUMO
Ischemia-reperfusion injury is common in clinical treatment.Free radical induced oxidative stress plays an important role in this process.Recently,it is reported that hydrogen can selectively scavenging hydroxyl radical in rodents,thus alleviate ischemia-reperfusion injury.Since hydrogen is easy to penetrate the barriers in the body with littie adverse effects,it is hopefully to become a promising agent against ischemia-reperfusion injury in the future.
RESUMO
Through teaching on diving site,teachers can help students strengthen the un-derstanding and memory on theoretical knowledge,translate the knowledge into practical skills,and obtain primary medical supervisal capabilities. Scene teaching in diving unites can help students learn about the great achievements in the past and the present situations. Such understandings would be good for the students’fostering the responsibility and mission sense as a diving physician. In conclusion,it is very necessary to teach on diving site in the teaching of diving medicine,and such teaching should be kept as an essential part.
RESUMO
Objective To study the galactagogue effect of Maidang Rutong Granules on the lactation rats.Methods The milk volume,morphology of mammary gland,serum prolactin level and pituitary acidophil number in lactation rats and the growth improvement in suckling mice were observed after administrating various dosages of Maidang Rutong Granules to lactation rats by gastric gavage.Results Maidang Rutong Granules can promote the dilation and hyperplasia of acinus cavity and conduit in mammary gland,reduce the mammary interlobular fat connective tissue,significantly increase pituitary acidophil number and serum prolactin level,increase the milk volume of lactation rats and their offspring's body weight.Conclusion Maidang Rutong Granules exhibit significant galactagogue effect on lactation rats.
