In order to further promote psoriasis slow disease management, the standard diagnosis and treatment of patients with psoriasis by psoriasis skin venereology branch of Chinese medical association professional committee and health services in anhui province association of psoriasis refers to southern China in 2020 action and GPA online training session for speaking, dandelion 15th session on November 27, 2020, in optimal successfully convened a doctor online platform.

        The meeting was co-chaired by Professor Shi Yuling, vice President of Shanghai Dermatology Hospital and director of Psoriasis Research Institute of Tongji University Medical School, and Professor Zhang Chunlei, director of dermatology of Peking University Third Hospital and head of psoriasis group of Dermatology branch of Chinese Medical Association. Changhai hospital affiliated to second military medical university, associate chief physician, combine traditional Chinese and western medicine skin disease professional committee members finish new ridge, professor of dermatology hospital of Shanghai medical director, the deputy director of institute of tongji university, psoriasis skin yang-feng ding, a professor at Shanghai jiaotong university school of medicine ruijin hospital dermatologist lrsa professor, deputy director of the first affiliated hospital of anhui medical university associate professor of zheng-wei zhu, yueyang hospital affiliated to Shanghai university of traditional Chinese medicine, chief physician, associate professor of dermatology, fu-lun li, a professor at the national dermatologist fellow and enterprises on behalf of a total of more than 400 people attended the online meeting.

        The meeting was co-chaired by Professor Shi Yuling and Professor Zhang Chunlei. First of all, Professor Bi Xinling gave a detailed explanation of the 2018 Psoriasis Diagnosis and treatment Guidelines in China from the aspects of concept, epidemiological characteristics, etiology and pathogenesis, diagnosis and differential diagnosis, clinical classification, severity classification and treatment. Professor Bi combined his own clinical experience to make a comprehensive analysis of the diversity and individuality of treatment strategies, and at the same time, described the obstinacy of disease relapse and efficacy decline after treatment. Finally, Professor Bi also emphasized the importance of basic translational research for clinical treatment.

        Professor Yang Feng Ding gave a detailed interpretation of Expert Consensus on Biological therapy for Psoriasis in China (2019). Mainly includes the formation of consensus and statement, set the basis of this agreement, this agreement covering a range of biological agents, all kinds of biological agents of clinical application, the application of biological treatment of principles and recommendations, biological treatment before the screening and treatment of monitoring, biological agents, and other treatment methods in the process of joint application, the curative effect of biological treatment of attenuation phenomenon and countermeasures and the application of the biological preparation special people. It was revealed that biological agents, as a new method, are being used more and more widely in clinical practice, which can rapidly and safely control psoriasis and improve the quality of life of patients. Meanwhile, attention should also be paid to the risk of infection brought by biological agents, and systematic screening of patients should be carried out before treatment.

        With the title of "Exploration of the pathogenesis of Psoriasis", Professor Li Xia brought the latest advances in this year's EADV Conference, which mainly covered the overall pathogenesis of psoriasis, the specific pathogenesis of different types of psoriasis, and the mechanisms related to the recurrence and long-term efficacy of psoriasis. The main pathogenesis of psoriasis and the major cytokines involved in the pathogenesis of psoriasis were explained. Meanwhile, the biotherapy strategies based on the pathogenesis of psoriasis were introduced. In the future, individualized therapy may be more preferred for different types of psoriasis. So that the attending doctors have a deeper understanding of the molecular level of psoriasis.

        Meeting in the second half of 2020 China psoriasis by Dr Zheng-wei zhu first introduces the monitoring project (CGPA) project, GPA is a long-term project, is for the purpose of continuous improvement on psoriasis cognition, and reveal its affect how individuals and the society as a whole, the first phase focused on in the prevalence of psoriasis and epidemic situation, future plans to add including diagnosis and treatment of psoriasis, complications to rule and improve patients' quality of life, the economic burden, etc. The objective of CGPA is to understand the distribution, disease status, disease burden, economic burden and quality of life of psoriasis patients in China. The establishment of a psoriasis research cohort, long-term follow-up of patients, to improve the status of health care for psoriasis, reduce the burden on patients, improve the quality of life of patients, so as to provide information for China's research on the disease, policy and health care. At the present stage, GPA psoriasis patients are recruited to participate in psoriasis questionnaire nationwide based on GPA China monitoring site and psoriasis specialty clinic, and the epidemiological survey of GPA psoriasis patients is completed. Then Dr. Zhu Zhengwei introduced CGPA electronic system training in detail.

        Professor Li Fuluns title is "Revealing the magic weapon in the treatment of psoriasis" -- biological agents. The main content includes biological agents gradually becoming the magic weapon in the treatment of psoriasis and how to choose the appropriate biological agents for patients. Different biological agents were introduced and compared in detail in terms of target, applicable population and safety. Cytokines are key to psoriasis inflammation, mainly including TNF-, IL-12, IL-23, and IL-17, among which IL-23 plays a "regulatory role" in the most critical response pathway and is an important core cytokine. Compared with traditional systematic treatment drugs, biological agents have better efficacy and bring a higher quality of life to patients.

        In the ensuing discussion link, dear professor in plain language, according to the actual clinical experience, around early recurrence of psoriasis symptoms and how to identify patients with recurrence, what kind of suitable for biological agents and incubation period for second liver is small 3 this world or TB patients treated three aspects how to use biological agents for answering questions and discussion.

        Finally, Professor Shi Yuling and Zhang Chunlei made a summary of this meeting, I believe that through this meeting can make the treatment of psoriasis more standardized, so that more patients with psoriasis can get personalized, optimal treatment. With the joint efforts of the psoriasis professional Committee, psoriasis outpatient department, psoriasis Research Center and GPA member unit in China, Chinese data can be provided for the global epidemiological resources of psoriasis, so that the results can better guide clinical work.
