ABSTRACT
Objective:To investigate the efficacy of atomization with budesonide, salbutamol, and acetylcysteine in the adjuvant treatment of bronchopneumonia in children.Methods:Seventy-two children with bronchopneumonia admitted to Huaiyuan Jingtu Hospital from July 2021 to June 2022 were retrospectively included in this study. These children were divided into BS and BSY groups according to different treatment methods. Based on conventional treatment, the BS group was given atomization treatment with budesonide and salbutamol, and the BSY group was given atomization treatment with budesonide, salbutamol, and acetylcysteine. After two courses of treatment, clinical efficacy, duration to improvements in symptoms and signs, adverse drug reactions, and changes in serum C-reactive protein and procalcitonin levels after treatment relative to those before treatment were compared between the two groups. The optimal medication plan was investigated.Results:The total response rate in the BSY group was 91.67% (33 cases/36 cases), which was significantly higher than 72.22% (26/36) in the BS group ( χ2 = 4.59, P = 0.032). The incidence of adverse drug reactions in the BSY group was 11.11% (4/36), which was significantly lower than 19.44% (7/36) in the BS group ( χ2 = 0.96, P = 0.326). After treatment, the levels of C-reactive protein and procalcitonin in the BSY group were (5.86 ± 5.66) mg/L and (2.59 ± 0.74) μg/L, respectively, which were lower than (15.64 ± 5.85) mg/L and (4.71 ± 0.93) μg/L in the BS group ( t = 7.20, 10.70, both P < 0.001). The durations to the disappearance of symptoms and signs including fever, cough, lung rales, and X-ray lung shadow in the BSY group were significantly shorter compared with the BS group ( t = 11.85, 4.19, 2.72, 2.39, all P < 0.05). Conclusion:Atomization with budesonide, salbutamol, and acetylcysteine in combination for the adjuvant treatment of bronchopneumonia in children can quickly relieve the clinical symptoms of children, improve the lung signs, reduce the degree of inflammation, and has a remarkable therapeutic effect on bronchopneumonia in children.
ABSTRACT
Objective@#To investigate the regulation of IL-25 on type Ⅱ innate lymphoid cells (ILC2s) activation in the pathogenesis of allergic fungal rhinosinusitis (AFRS).@*Methods@#Nasal mucosa tissues were collected from 16 AFRS patients and 12 patients, who underwent nasal endoscopic surgery for cerebrospinal rhinorrhea or skull base benign tumor during the period from June 2016 to June 2017 in Department of Rhinology, the First Affiliated Hospital of Zhengzhou University. Firstly, flow cytometry was used to detect ILC2s in nasal mucosa of both groups. Secondly, the expression of IL-25, IL-5 and IL-13 in nasal mucosa was detected by immunofluorescence and/or Western Blot assay. Finally, fungal extracts, IL-25 and glucocorticoids were used to stimulate nasal mucosal epithelial cells and tissues in vitro respectively to detect the regulatory effect of IL-25 on ILC2s. SPSS 16.0 software was used to analyze the data.@*Results@#The prevalence of ILC2s in nasal tissues was higher in patients with AFRS than those of the control group ((3.85±1.52)%(Mean±SD) vs (0.32±0.10)%, U=9.00, P<0.05). There was a positive correlation between the prevalence of ILC2s and the number of eosinophils in nasal mucosa of patients with ARFS (r=0.80, P<0.05). The expression of IL-25, IL-5 and IL-13 in nasal mucosa epithelium of AFRS group was significantly higher than that of the control group (0.49±0.13 vs 0.23±0.09, 0.23±0.05 vs 0.10±0.04, 0.31±0.08 vs 0.14±0.07, t value was 5.90, 7.21, 5.69, respectively, all P<0.05). Fungal stimulation enhanced the expression of IL-25 protein in nasal epithelial cells of both groups (0.67±0.19 vs 0.25±0.12 (AFRS group), 0.62±0.17 vs 0.27±0.16 (control group), q value was 8.65, 9.26, respectively, all P<0.05). In the IL-25 stimulated nasal mucosa at a concentration of 1, 10 and 100 ng/ml, the expression level of retinoid acid-related orphan receptor α (RORα) mRNA was 2.07±1.53, 5.06±0.93, 7.38±2.30, respectively; the expression level of GATA binding protein 3 (GATA3) mRNA was 3.58±1.29, 6.14±1.55, 7.64±2.28, respectively; the expression level of IL-5 protein was 0.21±0.06, 0.32±0.06, 0.38±0.10, respectively; the expression level of IL-13 was 0.52±0.13, 0.69±0.22, 0.82±0.21, respectively, which were significantly higher than that in the unstimulated nasal mucosa (1.00±0.00, 1.00±0.00, 0.11±0.05, 0.35±0.15, F value was 63.45, 59.27, 49.35, 20.20, respectively, all P<0.05). The up-regulation could be inhibited by dexamethasone (F value was 89.20, 92.47, 99.63, 49.82, respectively, all P<0.05).@*Conclusions@#Epithelial-derived IL-25 up-regulates the expression of IRC2s-dependent transcription factors RORα and GATA3 mRNA, which are positively correlated with elevated IL-13 and IL-5 expression levels in tissues, may be involved in AFRS inflammatory response, and are inhibited by glucocorticoids.
ABSTRACT
Objective To investigate the expression and clinical features of amplified in breast cancer 1 (AIB1) and epithelial mesenchymal transition (EMT) markers in human hepatocellular carcinoma and to observe the effect of AIB1 silencing by RNA interference (RNAi) on expression of EMT markers and invasiveness of HepG2 cells.Methods In this study,expression of AIB1,E-cadherin,Vimentin,ZO-1,and N-cadherin protein in 81 hepatocellular carcinomas were assessed through immunohistochemistry and clinicopathological significance was analyzed.After the lentiviral vector of AIB1 RNA interference was transfected into HepG2 cells,the expression of AIB1 and EMT markers was detected by real-time PCR and Western blot.The invasion and metastasis was evaluated by Transwell analysis.Results The expression of AIB1 protein was significantly up-regulated in the hepatocellular carcinoma tissue compared to the normal tumor adjacent tissue.The frequency of AIB1 overexpression in hepatocellular carcinomas with lymph node metastasis is 63％ (P ＜ 0.05).Correlation analysis demonstrated that the AIB1 protein expression was inversely correlated with E-cadherin,and positively correlated with Vimentin in hepatocellular carcinomas.After transfection with AIB1 targeting siRNA,the expression of AIB1 mRNA and protein decreased significantly (P ＜ 0.05).Knockdown of AIB1 expression increased the expression of E-cadherin and inhibited the expression of Vimentin.In addition,the invasion of HepG2 cells silenced AIB1 were significantly descented.Conclusion Above data suggests that overexpression of AIB1 might promote invasiveness and metastasis of cancer cells through regulation of E-cadherin and Vimentin expression in hepatocellular carcinomas.
ABSTRACT
Objective To investigate the influence of hospital-community integrated management mode on self behavior and blood glucose level in patients with typeⅡdiabetes .Method Three hundred and thirty-six patients with type II diabetes were treated with hospital-community integrated management. The index of biochemical indicators and self behaviors were compared between pre-and post-intervention.Result After intervention,the patients had improvements not only in medication compliance,rationale dieting,regular examination and self monitoring and physical exercises,but also in the indexes of biochemical indicators including fasting blood glucose(FBG),2 hour postprandial blood glucose(2 hBG), glycosylated hemoglobin(HbA1 c),(all P<0.05).Conclusion The hospital-community integrated management mode is helpful for the patients to form a right behavioral pattern and thus promoting the normalizations of biochemical indicators.
