Mass spectrometry-based quantitative proteomics has become an indispensable tool for tumor marker discovery.Stable isotope labeling with amino acid in cell culture(SILAC),as a representative of in vivo metabolic labeling strategy,is a simple and relatively quantitative assay for comparative proteomics.Two kinds of cultured cells are grown in the medium containing either a light or heavy isotope labeled essential amino acids.After several cell doublings,the heavy amino acids are introduced into the nascent polypeptides in a sequence-specific fashion and the natural amino acid is completely replaced by its isotopically labeled analog.Accuracy quantification would be feasible by analyzing the peak intensities of every same peptide pairs labeled with light or heavy isotopes by the mass spectrometry.Compared with chemical labeling,SILAC requires much less amount of labeled proteins,and it is an efficient,straightforward,reproducible and accurate approach in cell-based systems.This method can not only investigate the dynamics of protein abundance,but also monitor the variation of posttranslational modifications and protein-protein interactions qualitatively and quantitatively.It is a powerful and important quantitative proteomics tool for tumor marker discovery.

Objective:To investigate the clinical efficacy of different doses of budesonide/formoterol in the treatment of an acute exacerbation of chronic obstructive pulmonary disease in patients.Methods:A total of 200 inpatients with an acute exacerbation of chronic obstructive pulmonary disease graded C/D by global initiative for chronic obstructive lung disease (GOLD) staging system who received treatment in Jiuquan City People's Hospital, China from January to December in 2019 were included in this study. They were randomly divided into a control group and a treatment group ( n = 100/group). Based on anti-infection and expectorant treatment, the treatment group was given inhalation therapy (higher dose budesonide/formoterol, 320 μg/9 μg), while the control group was identically given inhalation therapy (lower dose budesonide/formoterol, 160 μg/4.5 μg), with a total course of 9 days in each group. Before treatment and at 5 and 9 days of treatment, procalcitonin (PCT), high-sensitivity C-reactive protein (hs-CRP), fractional exhaled nitric oxide (FeNO), percentage of eosinophils (EO%), partial pressure of oxygen (PaO 2), lactic acid, interleulin-6 (IL-6), forced expiratory volume in 1 second (FEV 1), the ratio of FEV 1/ forced vital capacity (FVC) were monitored in each group. COPD assessment test (CAT) score, modified Medical Research Council (mMRC) dyspnea score, 6-minute walking test (6MWT), and symptom improvement were determined in each group. Results:Before treatment, there were no significant differences in PCT and PaO 2 between the control and treatment groups (both P > 0.05). There were significant differences in PCT, PaO 2, FeNO, hs-CRP, E0 (%), IL-6, FEV 1, FEV 1/FVC, 6MWT, mMRC, cough, expectoration, shortness of breath and CAT score measured at 5 days of treatment between the treatment and control groups ( t = 2.416, 3.289, 3.982, 4.871, 3.332, 4.098, 5.253, 6.214, 3.843, 7.268, 5.387, 7.392, 5.398, 6.349, all P < 0.05). There were significant differences in PCT, PaO 2, FeNO, hs-CRP, E0 (%), IL-6, FEV 1/FVC, FEV 1, 6MWT, mMRC, cough, expectoration, shortness of breath and CAT score measured at 9 days of treatment between the treatment and control groups ( t = 2.508, 4.032, 2.948, 3.527, 3.118, 5.251, 5.325, 6.338, 2.907, 6.289, 3.246, 2.084, 2.151, 2.527, all P < 0.05). At 5 days of treatment, lactic acid level in the observation group was significantly lower than that in the control group ( t = 4.341, P < 0.05). At 9 days of treatment, there was no significant difference in lactic acid level between the control and observation groups ( t = 1.173, P > 0.05). There was no significant difference in the incidence of adverse reactions between the control and treatment groups [4%(4/100) vs. 5%(5/100), P > 0.05]. Conclusion:Inhalation of high doses of budesonide/formoterol can greatly improve pulmonary function, 6MWT performance, decrease mMRC and CAT scores, alleviate cough, expectoration, shortness of breath, and decrease serum levels of FeNO, hs-CRP, E0(%), IL-6 and other inflammatory factors. Inhalation of higher doses of budesonide/formoterol exhibits better efficacy in the treatment of an acute exacerbation of chronic obstructive pulmonary disease in patients than inhalation of lower doses of budesonide/formoterol.

Objective To analyze the infection situation and risk factors of Helicobacter pylori (Hp) in children in Yulin, Shaanxi province. Methods A total of 374 preschool children with digestive tract symptoms in Yulin area from December 2019 to December 2020 were selected. All the research object of personal data by using self-designed questionnaire (gender, age), personal experiences and health habits (common tableware, common koubei brushing your teeth, wash your hands before the rice then empress), the life habits (whether diet, koubei utilities, brushing your teeth regularly to suck finger), socioeconomic status, place of residence, with the number of living, family economic income), caregivers has a history of stomach problems (parents, nanny) And so on. The investigation method is the combination of telephone inquiry and on-site investigation. 3ml fasting venous blood was collected, and the supernatant was centrifuged. Serum IL-17 and IL-10 levels were determined by ENZYme-linked immunosorbent assay, and Treg and Th17 cell levels were determined by flow cytometry. Hp infection was detected by 14C urea breath test. Univariate analysis and logistic regression were used to analyze the independent risk factors of Hp infection in children. Results Eighty-three of the 374 children were infected with Hp, and the infection rate was 22.19%. The levels of Treg and IL-10 in peripheral blood of Hp infected children were significantly lower than those of non-hp infected children (P<0.05). The levels of Th17 and IL-17 in peripheral blood of children with Hp infection were significantly higher than those without Hp infection (P<0.05). In univariate analysis, there were statistically significant differences between the two groups in age, parental education level, per capita monthly income, sharing tableware, sharing toothbrushing cups, washing hands before and after meals, sucking fingers, parents' knowledge of Hp, and caregivers' history of stomach disease (P<0.05). Logistic regression analysis showed that sharing tableware, sharing toothbrushing cups, sucking fingers, parents' lack of knowledge about Hp, and caregivers' history of gastric diseases were independent risk factors for Hp infection in children (P<0.05). Conclusion The infection rate of Hp in children is high, and Hp infection can cause immune system dysfunction in children. It is necessary to take targeted and effective clinical measures to prevent Hp infection.
