【摘要】:研究目的: 本文通過應(yīng)用酶聯(lián)免疫吸附劑測定(enzyme linked immunosorbentassay,ELISA)檢測血清中的DcR3基因在IPF患者、類風(fēng)濕肺(RA-ILD)患者及健康體檢患者血清中的表達水平,進一步證實DcR3參與肺間質(zhì)纖維化形成。 研究方法: 1、實驗分組(共3組): 試驗組A:特發(fā)性肺纖維化(IPF)患者20例,年齡為53-74歲,平均年齡為62歲。 試驗組B:類風(fēng)濕肺(RA-ILD)患者20例,年齡為38-59歲,平均年齡為44歲。 對照組C:健康體檢患者20例,年齡為22-47歲,平均年齡為37歲。 2、入組標準: (1)A組:特發(fā)性肺間質(zhì)纖維化(IPF)患者20例,標本來源于靜脈血。標本均選自2011年10月——2012年6月期間在吉林大學(xué)第二醫(yī)院呼吸內(nèi)科治療的患者。IPF入組標準:1、符合2011年3月,美國胸科學(xué)會(ATS),歐洲呼吸學(xué)會(ERS)和拉丁美洲胸科學(xué)會在AMJ Respir critcare Med雜志聯(lián)合發(fā)表特發(fā)性肺間質(zhì)纖維化診治循證指南的診斷標準;2、患者除外惡性腫瘤疾。3、患者除外其他疫系統(tǒng)性疾病,如系統(tǒng)系紅斑狼瘡、風(fēng)濕性關(guān)節(jié)炎、硬皮病等。 (2)B組:類風(fēng)濕性關(guān)節(jié)炎合并肺間質(zhì)損傷(RA-ILD)患者20例:標本來源于靜脈血。標本均選自2011年10月——2012年6月期間在吉林大學(xué)第二醫(yī)院呼吸內(nèi)科治療的患者,RA-ILD入組標準:1、符合2010年4期出版的《中國類風(fēng)濕關(guān)節(jié)炎診治指南》中風(fēng)濕性關(guān)節(jié)炎的診斷標準,且伴有間質(zhì)性肺損傷的患者;2、患者除外惡性腫瘤疾病。 (3)C組:健康體檢患者20例,標本來源于靜脈血。標本均選自2011年10月——2012年6月期間在吉林大學(xué)第二醫(yī)院呼吸內(nèi)科門診體檢的健康患者,,設(shè)為陰性對照組。 3、收集標本: 取入組患者的外周血3ml,離心10分鐘(3000轉(zhuǎn)/分)后,取血清200ul備用,將其保存于-20℃或-70℃冰柜中,使用時應(yīng)注意避免反復(fù)凍融。 4、血清中DcR3蛋白檢測: 酶聯(lián)免疫吸附劑測定(ELISA) 5、統(tǒng)計方法: 所有實驗所得數(shù)據(jù)均應(yīng)用SPSS19.0統(tǒng)計軟件處理,計數(shù)資料比較用χ2檢驗,以P<0.05為差異有統(tǒng)計學(xué)意義。結(jié)果用均值±標準差(x±s)表示。 結(jié)果: 1、IPF組(A組)中DcR3表達水平明顯高于健康體檢組(C組),兩組之間存在顯著差異(P0.05),有統(tǒng)計學(xué)意義。 2、RA-ILD組(B組)中DcR3表達水平明顯高于健康體檢組(C組),兩組表達率之間存在顯著差異(#P0.05),有統(tǒng)計學(xué)意義。 3、IPF組(A組)與RA-ILD組(B組),兩組表達率之間不存在差異(△P>0.05),無統(tǒng)計學(xué)意義。 結(jié)論: 特發(fā)性肺間質(zhì)纖維化患者(A組)和類風(fēng)濕肺患者(B組)血清中DcR3基因表達水平,均高于健康體檢患者(C組),故進一步確定DcR3基因與IPF及RA-ILD的相關(guān)性,明確DcR3基因參與肺間質(zhì)纖維化的發(fā)生發(fā)展過程。但DcR3在其IPF及RA-ILD中的作用機理有待于進一步探索及研究。且實驗中采用OD結(jié)果進行統(tǒng)計分析比陽性百分率統(tǒng)計分析更敏感。
[Abstract]:Objectives of the study:The expression of DcR3 gene in serum of IPF patients, rheumatoid lung disease RA-ILD patients and healthy controls was detected by enzyme linked immunosorbent Elisa. It is further proved that DcR3 is involved in the formation of pulmonary interstitial fibrosis.Research methods:1. Experimental groups (3 groups):Group A: 20 patients with idiopathic pulmonary fibrosis (IPF), aged from 53 to 74 years, with an average age of 62 years.Group B: 20 patients with rheumatoid lung disease, aged 38 to 59 years, with an average age of 44 years.Control group C: 20 healthy physical examination patients, age 22-47 years old, the average age is 37 years old.2. Entry criteria:Group A: 20 patients with idiopathic pulmonary interstitial fibrosis (IPF).The specimens were collected from patients treated in Department of Respiratory Medicine, Jilin University second Hospital from October 2011 to June 2012.AMJ Respir critcare Med published the diagnostic criteria for the diagnosis and treatment of idiopathic pulmonary interstitial fibrosis with the exception of patients with malignant neoplasmsOther systemic diseases,Such as systemic lupus erythematosus, rheumatoid arthritis, scleroderma and so on.Group B: 20 patients with rheumatoid arthritis complicated with pulmonary interstitial injury (RA-ILD).The specimens were collected from patients who were treated in Department of Respiratory Medicine, Jilin University second Hospital from October 2011 to June 2012, according to the criteria for the diagnosis and treatment of rheumatoid arthritis published in 4 issues of 2010 in the Chinese guidelines for the diagnosis and treatment of Rheumatoid Arthritis.Patients with interstitial lung injury were excluded from malignant neoplasms.Group C: 20 healthy persons with venous blood.The specimens were collected from healthy patients who were examined in Department of Respiratory Medicine, Jilin University second Hospital from October 2011 to June 2012, and were set as negative control group.3. Collection of specimens:The peripheral blood of the patients was taken from 3 ml and centrifuged for 10 minutes. After centrifugation, serum 200ul was collected and stored in the freezer at -20 鈩
