Abstract
OBJECTIVE To evaluate the efficacy of platelet-rich plasma (PRP) in the treatment of androgenetic alopecia, as well as establish an effective treatment protocol and optimal PRP preparation procedure. METHODS We searched the PubMed, Scopus, Embase, Cochrane, CNKI, and Wanfang databases from inception to October 29, 2021, using PROSPERO's International Prospective Register of Systematic Reviews (registration ID: CRD42022295921). RESULTS The original literature search revealed 215 reviews; after duplication removal, 89 papers were eliminated, 95 were eliminated after reading the titles and abstracts, and eventually, 28 articles were included after reading the complete text. CONCLUSIONS PRP treatment for androgenetic alopecia is effective, and we recommend the following: (1) a PRP volume of at least 0.05 ml/cm(2) , preferably 0.1 ml/cm(2) ; (2) at least three consecutive treatments at an interval of 1 month; (3) intensive therapy is beneficial and can be provided from 3 to 6 months after continuous treatment; (4) objective indicators such as hair diameter, hair count; (5) long-term follow-up.

Abstract
BACKGROUND Chronic urticaria (CU) is a common and easily recurring skin disease in the world. Many trials have shown that autologous whole-blood or autologous serum acupoint injection therapy is effective in treating CU. There is currently no systematic review of this therapy. The program aims to evaluate the effectiveness and safety of this therapy in patients with CU. METHODS Literature search will be conducted at Medline, PubMed, Excerpt Medica Database, Springer, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Chinese Scientific Journal Database, and other databases. The search date is until May 2019. We will search for popular terms including CU and this therapy. Import the literature electronically. Duplicate documents will be deleted. The primary outcome is the urticaria activity score or other validated scales. Secondary outcomes included response rate, quality of life scale, recurrence rate, and adverse events. A systematic review and search for a randomized controlled trial of this therapy for CU. Implement the Cochrane RevMan V5.3 bias assessment tool to assess bias assessment risk, data integration risk, meta-analysis risk, and subgroup analysis risk (if conditions are met). The mean difference, standard MD, and binary data will be used to represent continuous results. RESULTS This study will provide a comprehensive review of the available evidence for the treatment of CU with this therapy. CONCLUSION This study will provide new evidence for assessing the effectiveness and side effects of this therapy for CU. Since the data is not individualized, there is no need for formal ethical approval. PROSPERO REGISTRATION NUMBER CRD42019128364.
