研究设计:

病例对照研究 

Study design:

Case-Control study 

研究目的:

深入探究空气污染物影响银屑病发生发展的机制,明确二氧化氮体内代谢物与银屑病疾病的相关性,揭示空气污染物尤其是气态污染物二氧化氮促进银屑病发生发展的新机制,进而为避免空气污染物对银屑病疾病产生影响提供新的思路。  

Objectives of Study:

To explore the mechanism of air pollutants affecting the occurrence and development of psoriasis, to clarify the correlation between metabolites of nitrogen dioxide and psoriasis, and to reveal the new mechanism of air pollutants, especially gaseous pollutant nitrogen dioxide, promoting the occurrence and development of psoriasis, so as to provide new ideas for avoiding the impact of air pollutants on psoriasis.

主要指标

Outcome:

Psoriasis Area and Severity Index score

Type:

Primary indicator

测量时间点:

就诊时

测量方法:

PASI评分:根据PASI评分规则对银屑病患者进行疾病严重程度评分。

Measure time point of outcome:

All measurements were obtained at the time of the clinic visit

Measure method:

Peripheral blood samples were collected, with 5 mL venous blood drawn each time by professional nurses following standardized procedures. After whole blood centrifugation, serum nitrate levels were measured via ELISA. With patients’ informed consent, residual samples were stored at ?80?°C in the Dermatology Laboratory of Union Hospital for further research.After participants signed the informed consent form and completed preoperative examinations for biopsy, lesion and normal skin tissue samples

指标中文名:

游离脂肪酸水平

指标类型:

次要指标

Outcome:

Free fatty acid levels

Type:

Secondary indicator

测量时间点:

就诊时

测量方法:

采集外周血样本、由专业护士按规范化流程进行静脉采血一次,5 mL/次。全血离心取血清样本进行游离脂肪酸水平检测,剩余样本经患者的知情同意后,在协和医院皮肤科实验室-80℃冰箱冻存用于后续的研究。

Measure time point of outcome:

All measurements were obtained at the time of the clinic visit

Measure method:

Peripheral blood samples were collected and venous blood samples (5 mL/ time) were collected by professional nurses according to standardized procedures. The whole blood was centrifuged to obtain serum samples for the detection of free fatty acid levels. The remaining samples were frozen at -80℃ in the Dermatology laboratory of Peking Union Medical College Hospital for subsequent research after informed consent of the patients
