Correlation analysis of asthma and prognosis in 148 children with low immune function / 公共卫生与预防医学

Objective To analyze the effect of immune function on the condition and prognosis of asthma in children with asthma. Methods A total of 148 children with asthma diagnosed in Qinghai women and children's Hospital from January 2018 to January 2021 were included in the analysis, the immune function of the children was determined, and the information of all children was followed up for 6 months after treatment; compared The condition and follow-up prognosis of children with immunocompromised and normal immune function were analyzed and discussed, and the correlation between the expression levels of immunoglobulins (IgG, IgA, IgM) and the condition and short-term recurrence prognosis (6 months) of children was analyzed and discussed, so as to guide Prevention and clinical work. Statistical analysis was done using SPSS19.0. Results The average age of 148 children with recurrent respiratory tract infection in the study was (8.94±3.65) years old, including 70 male children. The condition of the children was evaluated and classified into mild/severe cases: 148 children in this study included mild cases. There were 98 cases and 50 severe cases. There were more males and lower BMI levels in severe children (P<0.05) . The levels of IgG, IgA and IgM in children were all lower in severe children (P<0.05) . The follow-up found that the proportion of relapses in critically ill children was higher (P<0.05). Comparing the levels of IgG, IgA, and IgM in mild and severe children, the average levels of IgG, IgA, and IgM in severe children were lower than those in the mild group, and the difference was statistically significant (P<0.05); recurrence within 6 months of follow-up Prognostic evaluation showed that 19 of the 148 children had relapse, and the levels of IgG, IgA, and IgM in severe relapsed children were significantly lower than those without relapse (P<0.05). Analysis of the relevant factors potentially affecting the prognosis of recurrence showed that gender (female) (OR=1.726) , BMI level (weight loss) (OR=1.613) , IgG expression level factor (low expression) (OR=1.898) , IgA expression Level factor (low expression) (OR=3.509) , IgM expression level factor (low expression) (OR=3.217) and disease factor (severe) (OR=3.619) were potential risk factors, which would increase the risk of poor prognosis. Conclusion The asthma attack in children with immunocompromised immune function is relatively severe, and the short-term recurrence probability is higher, which deserves clinical attention and preventive intervention.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

miR-205 promotes proliferation and invasion of laryngeal squamous cell carcinoma by suppressing CDK2AP1 expression

BACKGROUND: The aberrant expression of microRNAs (miRNAs) has been found in various types of cancer. miR-205 was reported to be upregulated in laryngeal squamous cell carcinoma (LSCC) tissues, however, the mechanisms by which miR-205 functions as a regulator of LSCC are largely unknown. RESULTS: In this study, Real-time qPCR and Western blot assay showed that expression of miR-205 was upregulated and expression of cyclin-dependent kinase 2-associated protein 1 (CDK2AP1) was downregulated in LSCC tissues. The expression levels of miR-205 were negatively related to those of CDK2AP1 in LSCC tissues and cell lines. Moreover, we found that miR-205 was the upstream regulator of CDK2AP1 and could suppress the CDK2AP1 expression in LSCC cells. 3-(4,5-dimethylthiazal-2-yl)-2,5-diphenyl-tetrazolium bromide assays and transwell invasion assay were performed to test the proliferation and invasion of LSCC cells. Gelatin zymography was used to detect the activity of MMP2 and MMP9. CDK2AP1, c-Myc and CyclinD1 expression in cells was assessed with Western blotting. We found that miR-205 was the upstream regulator of CDK2AP1 and could suppress the expression of CDK2AP1 in LSCC cells. In addition, miR-205 significantly induced cell proliferation and invasion by suppressing CDK2AP1 expression. Consistent with miR-205 inhibitors, overexpressed CDK2AP1 suppressed the activity of MMP2 and MMP9 and c-Myc and CyclinD1 expression in LSCC cells. CONCLUSION: These findings help us to better elucidate the molecular mechanisms of LSCC progression and provide a new theoretical basis to further investigate miR-205 as a potential biomarker and a promising approach for LSCC treatment.

Analysis of the correlation of prevalence in allergic rhinitis and other allergic diseases / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To obtain the prevalence of allergic rhinitis (AR) in different regions of northern China, to analyze the correlation and interaction between AR and bronchial asthma (BA) or atopic dermatitis (AD), and to provide reference for the prevention and treatment of allergic diseases such as AR.</p><p><b>METHODS</b>To obtain the indexes including age, occupation, atopic physical fitness, smoking, alcohol, lifestyle and so on. To explore the correlation between AR and BA or AD. From April 2007 to May 2010, the serum specific IgE (sIgE) was investigated in different regions (rural areas of Qingxian, Hebei; coastal fishing village of Bohai Bay, Huanghua; area of Wuling Mountain, Chengde; urban areas of Tianjin) by randomly multi-stage and cluster sampling, with total population of 1524.</p><p><b>RESULTS</b>The prevalence of AR, BA and AD were 9.1%, 5.4% and 6.0%.
